Timing of previous heart failure hospitalization as a prognostic factor for emergency department heart failure patients.

To investigate whether the timing of a previous hospital admission for acute heart failure (AHF) is a prognostic factor for AHF patients revisiting the emergency department (ED) in the subsequent 12-month follow-up. All ED AHF patients enrolled in the previously described EAHFE registry were stratified by the presence or absence of an AHF hospitalization admission in the prior 12 months. The primary outcome was 12-month all-cause mortality post ED visit. Secondary end points were hospital admission, prolonged hospitalization (> 7 days), mortality during hospitalization and a 90-day post-discharge adverse composite event (ACE) rate, defined as ED revisits due to AHF, hospitalizations due to AHF, or all-cause mortality. Outcomes were adjusted for baseline and AHF episode characteristics.Of 5,757 patients included, the median age was 84 years (IQR 77-88); 57% were women, and 3,759 (65.3%) had an AHF hospitalization in the previous 12 months. The 12-month mortality was 37% (41.7% vs. 28.3% p < 0.001), hospital admission was 76.1% (78.8% vs. 71.1% p < 0.001) ACE was 60.2% (65.1% vs. 50.5% p < 0.001). In the adjusted analysis, patients with AHF hospitalization in the prior 12 months had a higher mortality (HR = 1.41; 95% CI 1.27-1.56), 90-day ACE rate (HR = 1.45: 95% CI 1.32-1.59), and more hospital admissions (OR = 1.32; 95% CI 1.16-1.51), with shorter times since the previous hospitalization being related to the outcomes analyzed. One-year mortality, adverse events at 90 days, and readmission rates are increased in ED AHF patients previously admitted within the last 12 months.

Use of digoxin in the emergency department to treat patients with acute heart failure and its impact on short-term outcomes. / Uso de digoxina endovenosa en urgencias para tratar pacientes con insuficiencia cardiaca aguda y su impacto en la evolución a corto plazo.

OBJECTIVES: To analyze factors related to the use of digoxin to treat patients with acute heart failure (AHF) in emergency departments (EDs) and the impact of digoxin treatment on short-term outcomes. MATERIAL AND METHODS: We included patients diagnosed with AHF in 45 Spanish EDs. The patients, who were not undergoing long-term treatment for heart failure, were classified according to whether or not they were given intravenous digoxin in the ED. Fifty-one patient or cardiac decompensation episode variables were recorded to profile ED patients treated with digoxin. Outcome variables studied were the need for hospital admission, prolonged stay in the ED (> 24 hours) for discharged patients, prolonged hospitalization (> 7 days) for admitted patients, and all-cause in-hospital or 30-day mortality. The associations between digoxin treatment and the outcomes were studied with odds ratios (ORs) adjusted for patient and AHF episode characteristics. RESULTS: Data for 15 549 patients (median age, 83 years; 55% women) were analyzed; 1430 (9.2%) were treated with digoxin. Digoxin was used more often in women, young patients, and those with better New York Heart Association (NYHA) classifications but more severe cardiac decompensation, especially if the trigger was atrial fibrillation with rapid ventricular response. Admissions were ordered for 75.4% of the patients overall (81.6% of digoxin-treated patients vs 74.8% of nontreated patients; P .001). The ED stay was prolonged in 38.3% of patients discharged from the ED (52.9% of digoxin-treated patients vs 37.2% of nontreated patients; P .001). The duration of hospital stay was prolonged in 48.1% (digoxin-treated, 49.3% vs 47.9%; P = .385). In-hospital mortality was 7.2% overall (6.9% vs 7.2%, P= .712), and 30-day mortality was 9.7% (9.3% vs 9.7%, P = .625). ED use of digoxin was associated with a prolonged stay in the department (adjusted OR, 1.883; 95% CI, 1.359-2.608) but not with hospitalization or mortality. CONCLUSION: Digoxin continues to be used in one out of ten ED patients who are not already on long-term treatment with the drug. Digoxin use is associated with cardiac decompensation triggered by atrial fibrillation with rapid ventricular response, younger age, women, and patients with better initial NYHA function status but possibly more severe decompensation. Digoxin use leads to a longer ED stay but is safe, as it is not associated with need for admission, prolonged hospitalization, or short-term mortality.

OBJETIVO: Analizar los factores relacionados con el uso de digoxina en urgencias en pacientes con insuficiencia cardiaca aguda (ICA) y el impacto pronóstico a corto plazo. METODO: Se incluyeron pacientes diagnosticados de ICA en 45 servicios de urgencias españoles sin tratamiento crónico con digoxina, los cuales se dividieron según recibiesen digoxina endovenosa en urgencias o no. Se recogieron 51 variables relativas al paciente o al episodio de descompensación y se investigó el perfil del paciente tratado con digoxina en urgencias. Como variables evolutivas se investigaron la necesidad de ingreso, la estancia en urgencias prolongada (> 24 horas) en dados de alta y la hospitalización prolongada (> 7 días) en ingresados, y la mortalidad intrahospitalaria y a 30 días por cualquier causa. Se analizó si el tratamiento con digoxina se asoció a diferencias evolutivas, de forma cruda y ajustada a las características del paciente y el episodio de ICA. RESULTADOS: Se analizaron 15.549 pacientes (mediana = 83 años, mujeres = 55%), de los que 1.430 (9,2%) fueron tratados con digoxina. La digoxina se utilizó más en mujeres, pacientes jóvenes, en mejor clase funcional de la New York Heart Association (NYHA), pero con descompensaciones más graves y, sobre todo, cuando existía una fibrilación auricular (FA) con respuesta ventricular rápida como desencadenante. Se hospitalizó el 75,4% de pacientes (más frecuente en tratados con digoxina; 81,6% vs 74,8%, p 0,001), tuvo estancia prolongada en urgencias el 38,3% (52,9% vs 37,2%, p 0,001), hospitalización prolongada el 48,1% (49,3% vs 47,9%, p = 0,385), mortalidad intrahospitalaria el 7,2% (6,9% vs 7,2%, p = 0,712) y a 30 días el 9,7% (9,3% vs 9,7%, p = 0,625). El modelo ajustado mostró que el uso de digoxina en urgencias sólo se asoció con estancia prolongada en urgencias (OR = 1,883, IC 95% = 1,359-2,608), pero no con la necesidad de ingreso, hospitalización prolongada o mortalidad. CONCLUSIONES: La digoxina continúa utilizándose en uno de cada 10 pacientes con ICA atendidos en urgencias que no utilizaban este fármaco de manera habitual. Su uso se relaciona con un paciente cuya ICA ha sido descompensada por una FA con respuesta ventricular rápida, más joven y más frecuentemente mujer, en mejor clase funcional de la NYHA basal y con una descompensación posiblemente más grave. El uso de digoxina conlleva una estancia en urgencias más prolongada, pero su uso es seguro, pues no se asocia a la necesidad de ingreso, hospitalización prolongada o mortalidad a corto plazo.

Impact of the MEESSI-AHF tool to guide disposition decision-making in patients with acute heart failure in the emergency department: a before-and-after study.

OBJECTIVES: To determine the impact of risk stratification using the MEESSI-AHF (Multiple Estimation of risk based on the Emergency department Spanish Score In patients with acute heart failure) scale to guide disposition decision-making on the outcomes of ED patients with acute heart failure (AHF), and assess the adherence of emergency physicians to risk stratification recommendations. METHODS: This was a prospective quasi-experimental study (before/after design) conducted in eight Spanish EDs which consecutively enrolled adult patients with AHF. In the pre-implementation stage, the admit/discharge decision was performed entirely based on emergency physician judgement. During the post-implementation phase, emergency physicians were advised to 'discharge' patients classified by the MEESSI-AHF scale as low risk and 'admit' patients classified as increased risk. Nonetheless, the final decision was left to treating emergency physicians. The primary outcome was 30-day all-cause mortality. Secondary outcomes were days alive and out of hospital, in-hospital mortality and 30-day post-discharge combined adverse event (ED revisit, hospitalisation or death). RESULTS: The pre-implementation and post-implementation cohorts included 1589 and 1575 patients, respectively (median age 85 years, 56% females) with similar characteristics, and 30-day all-cause mortality was 9.4% and 9.7%, respectively (post-implementation HR=1.03, 95% CI=0.82 to 1.29). There were no differences in secondary outcomes or in the percentage of patients entirely managed in the ED without hospitalisation (direct discharge from the ED, 23.5% vs 24.4%, OR=1.05, 95% CI=0.89 to 1.24). Adjusted models did not change these results. Emergency physicians followed the MEESSI-AHF-based recommendation on patient disposition in 70.9% of cases (recommendation over-ruling: 29.1%). Physicians were more likely to over-rule the recommendation when 'discharge' was recommended (56.4%; main reason: need for hospitalisation for a second diagnosis) than when 'admit' was recommended (12.8%; main reason: no appreciation of severity of AHF decompensation by emergency physician), with an OR for over-ruling the 'discharge' compared with the 'admit' recommendation of 8.78 (95% CI=6.84 to 11.3). CONCLUSIONS: Implementing the MEESSI-AHF risk stratification tool in the ED to guide disposition decision-making did not improve patient outcomes.

Decisions to admit vs. discharge patients with acute heart failure from the emergency department: consistency with a measure of severity of decompensation and the impact on prognosis. / Decisión de hospitalización o alta en pacientes con insuficiencia cardiaca aguda en urgencias, su adecuación con la gravedad de la descompensación e impacto pronóstico.

OBJECTIVES: To analyze the consistency between decisions to discharge or admit patients with acute heart failure (AHF) treated in emergency departments (EDs) and the level of risk of adverse events, and to analyze the impact of decisions to discharge patients. MATERIAL AND METHODS: Prospective study of baseline clinical data collected from patients diagnosed with AHF in 16 Spanish emergency departments. Patients were stratified by severity of decompensated AHF based on MEESSI assessment (Multiple Estimation of Risk Based on the Spanish Emergency Department Score). The distribution of severity was described for patients who were hospitalized (overall and for departments receiving the largest number of admissions) and for discharged patients. We analyzed the data for discharged patients for associations with the following quality-of-care indicators: all-cause mortality of less than 2% at 30 days, revisits to the ED for AHF in less than 10% of patients within 7 days of discharge, and revisits to the ED or admission for AHF in less than 20% within 30 days of discharge. RESULTS: We included 2855 patients with a median (interquartile range) age of 84 (76-88) years. Fifty-four percent were women, 1042 (36.5%) were classified as low risk, 1239 (43.4%) as intermediate risk, 301 (10.5%) as high risk, and 273 (9.6%) as very high risk. Thirty-day mortality rates by level of low to very high risk were 1.9%, 9.3%, 15.3%, and 38.4%, respectively. One-year mortality rates by risk level were 15.4%, 35.6%, 52.0%, and 74.2%. Admission rates by risk level were 62.2%, 77.4%, 87.0%, and 88.3%. Overall, 47.1% o patients discharged from the ED were in the 3 higher-risk categories (intermediate to very high), and 30.7% were in the lowest risk category. The 5 hospital areas receiving the most admissions, in order of lowest-to-highest risk classification, were internal medicine, the short-stay unit, cardiology, intensive care, and geriatrics. Rates and 95% CIs for quality-of-care indicators in patients discharged from EDs were as follows: 30-day mortality, 4.3% (3.0%-6.1%); ED revisits within 7 days, 11.4% (9.2%-14.0%), and ED revisits or admissions within 30 days, 31.5% (28.0%-35.1%). In patients classified as low risk on ED discharge, these percentages were lower, as follows, respectively: 0.5% (0.1%-1.8%), 10.5% (7.6%-14.0%), and 29.5% (26.6%-32.6%). CONCLUSION: We detected disparity between severity of AHF decompensation and the decision to discharge or admit patients. Outcomes in patients discharged from EDs do not reach the recommended quality-of-care standards. Reducing inconsistencies between severity of decompensation and ED decisions could help to improve quality targets.

OBJETIVO: Analizar cómo se ajusta la decisión de ingreso o alta del paciente con insuficiencia cardiaca aguda (ICA) atendido en urgencias a su riesgo de evento adverso, así como su impacto en el pronóstico en aquellos dados de alta desde urgencias. METODO: Se recogieron datos basales y clínicos de pacientes diagnosticados de ICA en 16 servicios de urgencias españoles. Los pacientes se estratificaron según la gravedad de la descompensación mediante la escala MEESSI y se analizó la distribución de dicha gravedad en hospitalizados (en conjunto, e individualmente para los servicios con mayor número de hospitalizaciones) y dados de alta desde urgencias. En este último grupo, se analizó el cumplimiento de los siguientes indicadores de calidad: mortalidad por cualquier causa a 30 días ( 2%), reconsulta a urgencias por ICA a 7 días posalta ( 10%), y reconsulta a urgencias u hospitalización por ICA a 30 días posalta ( 20%). RESULTADOS: Se incluyeron 2.855 pacientes (edad mediana = 84 años, RIC = 76-88; mujeres = 54%): 1.042 pacientes (36,5%) de riesgo bajo, 1.239 (43,4%) intermedio, 301 (10,5%) alto y 273 (9,6%) muy alto. La mortalidad a 30 días por categorías de riesgo fue 1,9%, 9,3%, 15,3% y 38,4%, respectivamente; la mortalidad al año 15,4%, 35,6%, 52,0% y 74,2%; y la hospitalización 62,2%, 77,4%, 87,0% y 88,3%. El 47,1% de pacientes dados de alta de urgencias tenía un riesgo incrementado (intermedio, alto o muy alto) y el 30,7% de hospitalizados eran de bajo riesgo. La gravedad de la descompensación según el servicio de hospitalización se incrementaba en el siguiente orden: medicina interna, corta estancia, cardiología, intensivos y geriatría. El 4,3% de pacientes dados de alta de urgencias (IC 95%: 3,0-6,1) falleció a los 30 días, el 11,4% (9,2-14,0) reconsultó en urgencias a los 7 días, y el 31,5% (28,0-35,1) reconsultó en urgencias o se hospitalizó a los 30 días. Si sólo se consideran los pacientes dados de alta de bajo riesgo, estos porcentajes descienden al 0,5% (0,1-1,8), 10,5% (7,6-14,0) y 29,5% (26,6-32,6), respectivamente. CONCLUSIONES: Existe disparidad entre la gravedad de la descompensación y la decisión en urgencias de hospitalizar o dar de alta a los pacientes con ICA. Los resultados que se obtienen en los pacientes dados de alta desde urgencias no alcanzan los estándares de calidad recomendados. Disminuir las incongruencias entre gravedad de la descompensación y toma de decisión podría contribuir a cumplir con estos estándares.

QT interval and short-term outcome in acute heart failure.

OBJECTIVE: To investigate the association of corrected QT (QTc) interval duration and short-term outcomes in patients with acute heart failure (AHF). METHODS: We analyzed AHF patients enrolled in 11 Spanish emergency departments (ED) for whom an ECG with QTc measurement was available. Patients with pace-maker rhythm were excluded. Primary outcome was 30-day all-cause mortality and secondary outcomes were need of hospitalization, in-hospital mortality and prolonged hospitalization (> 7 days). Association between QTc and outcomes was explored by restricted cubic spline (RCS) curves. Results were expressed as odds ratios (OR) and 95%CI adjusted by patients baseline and decompensation characteristics, using a QTc = 450 ms as reference. RESULTS: Of 1800 patients meeting entry criteria (median age 84 years (IQR = 77-89), 56% female), their median QTc was 453 ms (IQR = 422-483). The 30-day mortality was 9.7%, while need of hospitalization, in-hospital mortality and prolonged hospitalization were 77.8%, 9.0% and 50.0%, respectively. RCS curves found longer QTc was associated with 30-day mortality if > 561 ms, OR = 1.86 (1.00-3.45), and increased up to OR = 10.5 (2.25-49.1), for QTc = 674 ms. A similar pattern was observed for in-hospital mortality; OR = 2.64 (1.04-6.69), for QTc = 588 ms, and increasing up to OR = 8.02 (1.30-49.3), for QTc = 674 ms. Conversely, the need of hospitalization had a U-shaped relationship: being increased in patients with shorter QTc [OR = 1.45 (1.00-2.09) for QTc = 381 ms, OR = 5.88 (1.25-27.6) for the shortest QTc of 200 ms], and also increasing for prolonged QTc [OR = 1.06 (1.00-1.13), for QTc = 459 ms, and reaching OR = 2.15 (1.00-4.62) for QTc = 588 ms]. QTc was not associated with prolonged hospitalization. CONCLUSION: In ED AHF patients, initial QTc provides independent short-term prognostic information, with increasing QTc associated with increasing mortality, while both, shortened and prolonged QTc are associated with need of hospitalization.

The influence of comorbidities on the prognosis after an acute heart failure decompensation and differences according to ejection fraction: Results from the EAHFE and RICA registries.

OBJECTIVE: The role of comorbidities in heart failure (HF) outcome has been previously investigated, although mostly individually. We investigated the individual effect of 13 comorbidities on HF prognosis and looked for differences according to left-ventricular ejection fraction (LVEF), classified as reduced (HFrEF), mildly-reduced (HFmrEF) and preserved (HFpEF). METHODS: We included patients from the EAHFE and RICA registries and analysed the following comorbidities: hypertension, dyslipidaemia, diabetes mellitus (DM), atrial fibrillation (AF), coronary artery disease (CAD), chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), heart valve disease (HVD), cerebrovascular disease (CVD), neoplasia, peripheral artery disease (PAD), dementia and liver cirrhosis (LC). Association of each comorbidity with all-cause mortality was assessed by an adjusted Cox regression analysis that included the 13 comorbidities, age, sex, Barthel index, New York Heart Association functional class and LVEF and expressed as adjusted Hazard Ratios (HR) with 95% confidence intervals (95%CI). RESULTS: We analysed 8,336 patients (82 years-old; 53% women; 66% with HFpEF). Mean follow-up was 1.0 years. Respect to HFrEF, mortality was lower in HFmrEF (HR:0.74;0.64-0.86) and HFpEF (HR:0.75;0.68-0.84). Considering patients all together, eight comorbidities were associated with mortality: LC (HR:1.85;1.42-2.42), HVD (HR:1.63;1.48-1.80), CKD (HR:1.39;1.28-1.52), PAD (HR:1.37;1.21-1.54), neoplasia (HR:1.29;1.15-1.44), DM (HR:1.26;1.15-1.37), dementia (HR:1.17;1.01-1.36) and COPD (HR:1.17;1.06-1.29). Associations were similar in the three LVEF subgroups, with LC, HVD, CKD and DM remaining significant in the three subgroups. CONCLUSION: HF comorbidities are associated differently with mortality, LC being the most associated with mortality. For some comorbidities, this association can be significantly different according to the LVEF.

Emergency department direct discharge compared to short-stay unit admission for selected patients with acute heart failure: analysis of short-term outcomes.

Short stay unit (SSU) is an alternative to conventional hospitalization in patients with acute heart failure (AHF), but the prognosis is not known compared to direct discharge from the emergency department (ED). To determine whether direct discharge from the ED of patients diagnosed with AHF is associated with early adverse outcomes versus hospitalization in SSU. Endpoints, defined as 30-day all-cause mortality or post-discharge adverse events, were evaluated in patients diagnosed with AHF in 17 Spanish EDs with an SSU, and compared by ED discharge vs. SSU hospitalization. Endpoint risk was adjusted for baseline and AHF episode characteristics and in patients matched by propensity score (PS) for SSU hospitalization. Overall, 2358 patients were discharged home and 2003 were hospitalized in SSUs. Discharged patients were younger, more frequently men, with fewer comorbidities, had better baseline status, less infection, rapid atrial fibrillation and hypertensive emergency as the AHF trigger, and had a lower severity of AHF episode. While their 30-day mortality rate was lower than in patients hospitalized in SSU (4.4% vs. 8.1%, p < 0.001), 30-day post-discharge adverse events were similar (27.2% vs. 28.4%, p = 0.599). After adjustment, there were no differences in the 30-day risk of mortality of discharged patients (adjusted HR 0.846, 95% CI 0.637-1.107) or adverse events (1.035, 0.914-1.173). In 337 pairs of PS-matched patients, there were no differences in mortality or risk of adverse event between patients directly discharged or admitted to an SSU (0.753, 0.409-1.397; and 0.858, 0.645-1.142; respectively). Direct ED discharge of patients diagnosed with AHF provides similar outcomes compared to patients with similar characteristics and hospitalized in a SSU.

Impact of worsening renal function detected at emergency department arrival on acute heart failure short-term outcomes.

BACKGROUND AND IMPORTANCE: Deterioration of renal function with respect to baseline during an acute heart failure (AHF) episode is frequent, but impact on outcomes is still a matter of debate. OBJECTIVE: To investigate the association of creatinine deterioration detected at emergency department (ED) arrival and short-term outcomes in patients with AHF. DESIGN: Secondary analysis of a large multipurpose registry. SETTINGS AND PARTICIPANTS: Patients with AHF were diagnosed in 10 Spanish ED for whom a previous baseline creatinine was available. EXPOSURE: Difference between creatinine at ED arrival and at baseline was calculated (∂-creatinine). OUTCOME MEASURES AND ANALYSIS: Primary outcome was 30-day all-cause death, and secondary outcomes were inhospital all-cause death, prolonged hospitalization (>7 days) and 7-day postdischarge adverse events. Associations between ∂-creatinine and outcomes were explored using logistic regression by restricted cubic spline (RCS) curves and expressed as odds ratio (OR) with 95% confidence interval (CI), taking ∂-creatinine = 0 mg/dl as reference. Curves were adjusted by age, sex, comorbidities, patient baseline status, chronic treatments, and vitals and laboratory results at ED arrival. Interactions for the primary outcome also were investigated. MAIN RESULTS: We analyzed 3036 patients (median age = 82 years; IQR = 75-87; women = 55%), with ∂-creatinine ranged from -0.3 to 3 mg/dl. The 30-day mortality was 11.6%. Increments of ∂-creatinine were associated with progressive increase in risk of 30-day death, although adjustment attenuated this association: ∂-creatinine of 0.3/1/2/3 mg/dl were, respectively, associated with adjusted OR of 1.41 (1.02-1.95), 1.69 (1.02-2.80), 1.46 (0.56-3.80) and 1.27 (0.27-5.83). Distinctively significant higher risk was found for patients over 80 years old, female, nondiabetic, functionally disabled and on digoxin therapy. With respect to secondary outcomes, inhospital mortality was 8.1%, prolonged hospitalization was 33.6% and 7-day postdischarge adverse event was 9.7%. Inhospital death steadily increased with increments in ∂-creatinine [from 1.50 (1.04-2.17) with ∂-creatinine = 0.3 to 3.78 (0.78-18.3) with ∂-creatinine = 3], as well as prolonged hospitalization did [from 1.41 (1.11-1.77) to 2.24 (1.51-3.33), respectively]. Postdischarge adverse events were not associated with ∂-creatinine. CONCLUSION: WRF detected at ED arrival has prognostic value in AHF, being associated with increased risk of death and prolonged hospitalization. These associations showed different patterns of risk but, remarkably, risk started with increments as low as 0.3 mg/dl.

Effect of Flu Vaccination on Severity and Outcome of Heart Failure Decompensations.

OBJECTIVE: To investigate the relationship of seasonal flu vaccination with the severity of decompensation and long-term outcomes of patients with heart failure (HF). METHODS: We analyzed 6147 consecutively enrolled patients with decompensated HF who presented to 33 Spanish emergency departments (EDs) during January and February of 2018 and 2019, grouped according to seasonal flu vaccination status. The severity of HF decompensation was assessed by the Multiple Estimation of Risk Based on the Emergency Department Spanish Score in Patients With Acute Heart Failure (MEESSI-AHF) + MEESSI scale, need of hospitalization and in-hospital all-cause mortality. The long-term outcomes analyzed were 90-day postdischarge adverse events and 90-day all-cause death. Associations between vaccination, HF decompensation severity and long-term outcomes were explored by unadjusted and adjusted logistic and Cox regressions by using 14 covariables that could act as potential confounders. RESULTS: Overall median (IQR) age was 84 (IQR = 77-89) years, and 56% were women. Vaccinated patients (n = 1139; 19%) were older, had more comorbidities and had worse baseline status, as assessed by New York Heart Association class and Barthel index, than did unvaccinated patients (n = 5008; 81%). Infection triggering decompensation was more common in vaccinated patients (50% vs 41%; P < 0.001). In vaccinated and unvaccinated patients, high or very-high risk decompensation was seen in 21.9% and 21.1%; hospitalization occurred in 72.5% and 73.7%; in-hospital mortality was 7.4% and 7.0%; 90-day postdischarge adverse events were 57.4% and 53.2%; and the 90-day mortality rate was 15.8% and 16.6%, respectively, with no significant differences between cohorts. After adjusting, vaccinated decompensated patients with HF had decreased odds for hospitalization (OR = 0.823, 95%CI = 0.709-0.955). CONCLUSION: In patients with HF, seasonal flu vaccination is associated with less severe decompensations.

Influence of Meteorological Temperature and Pressure on the Severity of Heart Failure Decompensations.

OBJECTIVE: To investigate the relationship between ambient temperature and atmospheric pressure (AP) and the severity of heart failure (HF) decompensations. METHODS: We analysed patients coming from the Epidemioloy Acute Heart Failure Emergency (EAHFE) Registry, a multicentre prospective cohort study enrolling patients diagnosed with decompensated HF in 26 emergency departments (EDs) of 16 Spanish cities. We recorded patient and demographic data and maximum temperature (Tmax) and AP (APmax) the day before ED consultation. Associations between temperature and AP and severity endpoints were explored by logistic regression. We used restricted cubic splines to model continuous non-linear associations of temperature and AP with each endpoint. RESULTS: We analysed 16,545 patients. Daily Tmax and APmax (anomaly) of the day before patient ED arrival ranged from 0.8 to 41.6° and from - 61.7 to 69.9 hPa, respectively. A total of 12,352 patients (75.2%) were hospitalised, with in-hospital mortality in 1171 (7.1%). The probability of hospitalisation by HF decompensation showed a U-shaped curve versus Tmax and an increasing trend versus APmax. Regarding temperature, hospitalisation significantly increased from 20 °C (reference) upwards (25 °C: OR = 1.12, 95% CI = 1.04-1.21; 40 °C: 1.65, 1.13-2.40) and below 5.4 °C (5 °C: 1.21, 1.01-1.46). Concerning the mean AP of the city (anomaly = 0 hPa), hospitalisation increased when APmax (anomaly) was above + 7.0 hPa (atmospheric anticyclone; + 10 hPa: 1.14, 1.05-1.24; + 30 hPa: 2.02. 1.35-3.03). The lowest probability of mortality also corresponded to cold-mild temperatures and low AP, with a significant increased risk only found for Tmax above 24.3 °C (25 °C: 1.13, 1.01-1.27; 40 °C: 2.05, 1.15-3.64) and APmax (anomaly) above + 3.4 hPa (+ 10 hPa: 1.21, 1.07-1.36; + 30 hPa: 1.73, 1.06-2.81). Sensitivity analysis confirmed the main analysis results. CONCLUSION: Temperature and AP are independently associated with the severity of HF decompensations, with possible different effects on the need for hospitalisation and in-hospital mortality.

Impact of congestion and perfusion status in the emergency department on severity of decompensation and short-term prognosis in patients with acute heart failure.

AIMS: To assess whether symptoms/signs of congestion and perfusion in acute heart failure (AHF) evaluated at patient arrival to the emergency department (ED) can predict the severity of decompensation and short-term outcomes. METHODS AND RESULTS: We included patients from the Epidemiology of AHF Emergency Registry (EAHFE Registry). We registered seven clinical surrogates of congestion and five of hypoperfusion. Patients were grouped according to severity of congestion/hypoperfusion. We assessed the need for hospitalization, in-hospital all-cause mortality for patients needing hospitalization, and prolonged hospitalization for patients surviving the decompensation episode. Outcomes were adjusted for patient characteristics and the coexistence of congestion and hypoperfusion. We analysed 18 120 patients (median = 83 years, interquartile range = 76-88; women = 55.7%). Seventy-two per cent presented >2 signs/symptoms of congestion and 18% had at least 1 sign/symptom of hypoperfusion. Seventy-five per cent were hospitalized with in-hospital death in 9% and prolonged hospitalization in 47% discharged alive. The presence of congestion/hypoperfusion was independently associated with poorer outcomes. An increase in the number of signs/symptoms of congestion was associated with increased risk of hospitalization (P < 0.001) and prolonged stay (P = 0.011), but not mortality (P = 0.06). Increased signs/symptoms of hypoperfusion were associated with hospitalization (P < 0.001) and mortality (P < 0.001), but not prolonged stay (P = 0.227). In the combined model, including congestion and hypoperfusion, both had additive effects on hospitalization, in-hospital mortality was driven by hypoperfusion and no differences were observed for prolonged hospitalization. CONCLUSION: The presence of congestion/hypoperfusion at ED arrival is a simple clinical marker associated with a higher risk of severity/adverse short-term outcomes.

Emergency department observation of patients with acute heart failure prior to hospital admission: impact on short-term prognosis. / Observación en urgencias previa a la hospitalización en pacientes con insuficiencia cardiaca aguda: impacto sobre el pronóstico a corto plazo.

OBJECTIVES: To analyze whether short-term outcomes are affected when patients diagnosed with acute heart failure (AHF) spend time in an emergency department observation unit (EDOU) before hospital admission. MATERIAL AND METHODS: Baseline and emergency episode data were collected for patients diagnosed with AHF in the EDs of 15 Spanish hospitals. We analyzed crude and adjusted associations between EDOU stay and 30-day mortality (primary outcome) and in-hospital mortality and a prolonged hospital stay of more than 7 days (secondary outcomes). RESULTS: A total of 6597 patients with a median (interquartile range) age of 83 (76-88 years) were studied. Fifty-five percent were women. All were hospitalized for AHF (50% in internal medicine wards, 23% in cardiology, 11% in geriatrics, and 16 in other specialties. Of these patients, 3241 (49%) had had EDOU stays and 3350 (51%) had been admitted immediately, with no EDOU stay. Having an EDOU stay was associated with female sex, dementia or chronic obstructive pulmonary disease, long-term treatment with certain drugs for heart failure, greater baseline deterioration in function, and a higher degree of decompensation. Patients in the EDOU group were more often admitted to an internal medicine ward and had shorter stays; cardiology, geriatric, and intensive care admissions were less likely to have had an EDOU stay. Overall, 30-day mortality was 12.6% (13.7% in the EDOU group and 11.4% in the no-EDOU group; P = .004). In-hospital mortality was 10.4% overall (EDOU, 11.1% and no-EDOU, 9.6%; P = .044). Prolonged hospitalization occurred in 50.0% (EDOU, 48.7% and no-EDOU, 51.2%; P = .046). After adjusting for between-group differences, the EDOU stay was not associated with 30-day mortality (hazard ratio, 1.14; 95% CI, 0.99-1.31). Odds ratios for associations between EDOU stay and in-hospital mortality and prolonged hospital stay, respectively, were 1.09 (95% CI, 0.92-1.29) and 0.91 (95% CI, 0.82-1.01). CONCLUSION: Although mortality higher in patients hospitalized for AHF who spend time in an EDO, the association seems to be accounted for by their worse baseline situation and the greater seriousness of the decompensation episode, not by time spent in the EDOU.

OBJETIVO: Analizar si la estancia en el área de observación de urgencias (AOU) de pacientes que han sido diagnosticados de insuficiencia cardiaca aguda (ICA) y que deben ingresar está asociada con algún cambio en la evolución a corto plazo. METODO: Se recogieron datos basales y clínicos de pacientes diagnosticados de ICA en el servicio de urgencias de 15 hospitales españoles. Se analizó la asociación cruda y ajustada de la estancia en el AOU previa a la hospitalización con mortalidad a 30 días (objetivo primario) y con mortalidad intrahospitalaria e ingreso prolongado (> 7 días) (objetivos secundarios). RESULTADOS: Se incluyeron 6.597 pacientes (mediana = 83 años, RIC = 76-88; mujeres = 55%) hospitalizados por ICA (50% en medicina interna, 23% en cardiología, 11% en geriatría y 16% en otros servicios); de ellos, 3.241 (49%) permanecieron en observación en urgencias (grupo AOU) y 3.350 (51%) hospitalizaron sin observación previa (grupo no-AOU). La observación en urgencias se asoció con ser mujer, tener demencia o enfermedad pulmonar obstructiva crónica, recibir crónicamente fármacos específicos para insuficiencia cardiaca, mayor deterioro funcional basal y mayor gravedad de la descompensación. El grupo AOU más frecuentemente hospitalizó en medicina interna y corta estancia, y menos frecuentemente en cardiología, geriatría y cuidados intensivos. La mortalidad a 30 días fue del 12,6% (AOU = 13,7%, no-AOU = 11,4%, p = 0,004); la mortalidad intrahospitalaria fue del 10,4% (AOU = 11,1%, no-AOU = 9,6%, p = 0,044) y el ingreso prolongado del 50,0% (AOU = 48,7%, no-AOU = 51,2%, p = 0,046). Tras ajustar por las diferencias entre grupos, la estancia en observación en urgencias no se asoció con mortalidad a 30 días (HR = 1,14, IC 95% = 0,99-1,31), mortalidad intrahospitalaria (OR = 1,09, IC 95% = 0,92-1,29) o estancia prolongada (OR = 0,91, IC 95% = 0,82-1,01). CONCLUSIONES: Aunque los pacientes hospitalizados por ICA que permanecen en observación en urgencias presentan mayor mortalidad, esta asociación parece explicarse por su peor situación de base y la mayor gravedad del episodio de descompensación y no por su paso por el AOU.

Ambient temperature and atmospheric pressure at discharge as precipitating factors in immediate adverse events in patients treated for decompensated heart failure.

To investigate the relationship of ambient temperature and atmospheric pressure (AP) at patient discharge after an episode of acute heart failure (AHF) with very early post-discharge adverse outcomes. We analyzed 14,656 patients discharged after an AHF episode from 26 hospitals in 16 Spanish cities. The primary outcome was the 7-day post-discharge combined adverse event (emergency department -ED- revisit or hospitalization due to AHF, or all-cause death), and secondary outcomes were these three adverse events considered individually. Associations (adjusted for patient and demographic conditions, and length of stay -LOS- during the AHF index episode) of temperature and AP with the primary and secondary outcomes were investigated. We used restricted cubic splines to model the continuous non-linear association of temperature and AP with each endpoint. Some sensitivity analyses were performed. Patients were discharged after a median LOS of 5 days (IQR = 1-10). The highest temperature at discharge ranged from - 2 to 41.6 °C, and AP was from 892 to 1037 hPa. The 7-day post-discharge combined event occurred in 1242 patients (8.4%), with percentages of 7-day ED-revisit, hospitalization and death of 7.8%, 5.1% and 0.9%, respectively. We found no association between the maximal temperature and AP on the day of discharge and the primary or secondary outcomes. Similarly, there were no significant associations when the analyses were restricted to hospitalized patients (median LOS = 7 days, IQR = 4-11) during the index event, or when lag-1, lag-2 or the mean of the 3 post-discharge days (instead of point estimation) of ambient temperature and AP were considered. Temperature and AP on the day of patient discharge are not independently associated with the risk of very early adverse events during the vulnerable post-discharge period in patients discharged after an AHF episode.

Evaluation of the HEFESTOS scale to predict outcomes in emergency department acute heart failure patients.

The HEFESTOS scale was developed in 14 Spanish primary care centres and validated in 9 primary care centres of other European countries. It showed good performance to predict death/hospitalisation during the first 30 days after an episode of acute heart failure (AHF), with c-statistics of 0.807/0.730 in the derivation/validation cohorts. We evaluated this scale in the emergency department (ED) setting, comparing it to the EHMRG and MEESSI scales in the ED and the EFFECT and GWTG scales in hospitalised patients, to predict 30-day outcomes, including death and hospitalisation. Consecutive AHF patients were enrolled in 34 Spanish EDs in January-February 2016, 2018, and 2019 with variables needed to calculate outcome scores. Thirty-day hospitalisation/death (together and separately) and post-discharge combined adverse event (ED revisit or hospitalisation for AHF or all-cause death) were determined for patients discharged home after ED care. Predictive capacity was assessed by c-statistic with 95% confidence intervals. Of 10,869 patients, 4,044 were included (median age: 83 years, 54% women). The performance of HEFESTOS was modest for 30-day hospitalisation/death, c-statistic=0.656 (0.637-0.675), hospitalisation, 0.650 (0.631-0.669), and death, 0.610 (0.576-0.644). Of 1,034 patients with scores for the 5 scales, HEFESTOS had the numerically highest c-statistic for hospitalisation/death at 30 days, 0.666 (0.627-0.704), vs. MEESSI= 0.650 (0.612-0.687, p=0.51), EFFECT=0.633 (0.595-0.672, p=0.21), GWTG=0.618 (0.578-0.657, p=0.06) and EHMRG=0.617 (0.577-0.704, p=0.07). Similar modest performances were observed for predicting hospitalisation [ranging from HEFESTOS=0.656 (0.618-0.695) to GWTG=0.603 (0.564-0.643)]. Conversely, prediction of 30-day death was good with the MEESSI=0.787 (0.728-845), EFFECT=0.754 (0.691-0.818) and GWTG=0.749 (0.689-0.809) scales, and modest with EHMRG=0.649 (0.581-0.717) and HEFESTOS=0.610 (0.538-0.683). Although the HEFESTOS scale was numerically better for predicting 30-day hospitalisation/death in ED AHF patients, its modest performance precludes routine use. Only 30-day mortality was adequately predicted by some scales, with the MEESSI achieving the best results.

Short-term outcomes by chronic betablocker treatment in patients presenting to emergency departments with acute heart failure: BB-EAHFE.

AIMS: To evaluate the association between chronic treatment with betablockers (BB) and the severity of decompensation and short-term outcomes of patients with acute heart failure (AHF). METHODS AND RESULTS: We consecutively included all patients presenting with AHF to 45 Spanish emergency departments (ED) during six different time-periods between 2007 and 2018. Patients were stratified according to whether they were on chronic treatment with BB at the time of ED consultation. Those receiving BB were compared (adjusted odds ratio-OR-with 95% confidence interval-CI-) with those not receiving BB group in terms of in-hospital and 7-day all-cause mortality, need for hospitalization, and prolonged length of stay (≥7 days). Among the 17 923 recruited patients (median age: 80 years; 56% women), 7795 (43%) were on chronic treatment with BB. Based on the MEESSI-AHF risk score, those on BB were at lower risk. In-hospital mortality was observed in 1310 patients (7.4%), 7-day mortality in 765 (4.3%), need for hospitalization in 13 428 (75.0%), and prolonged length of stay (43.3%). After adjustment for confounding, those on chronic BB were at lower risk for in-hospital all-cause mortality (OR = 0.85, 95% CI = 0.79-0.92, P < 0.001); 7-day all-cause mortality (OR = 0.77, 95% CI = 0.70-0.85, P < 0.001); need for hospitalization (OR = 0.89, 95% CI = 0.85-0.94, P < 0.001); prolonged length of stay (OR = 0.90, 95% CI = 0.86-0.94, P < 0.001). A propensity matching approach yielded consistent findings. CONCLUSION: In patients presenting to ED with AHF, those on BB had better short-term outcomes than those not receiving BB.

Evaluation of the effect of intravenous nitroglycerine on short-term survival of patients with acute heart failure according to congestion and perfusion status at emergency department arrival.

OBJECTIVES: We investigated if the phenotypic classification of acute heart failure (AHF) based on the number of signs/symptoms of congestion and hypoperfusion at emergency department (ED) arrival identifies subgroups in which intravenous (IV) nitroglycerine (NTG) use improves short-term survival. METHODS: We included consecutive AHF patients diagnosed in 45 Spanish EDs, who were grouped according to phenotype severity. The main outcome was 30-day all-cause death. Propensity scores (PS) for NTG use were generated using variables associated with death. Analysis of interaction was performed in subgroups of patients based on congestion, hypoperfusion, age, sex, coronary artery disease (CAD), left ventricular ejection fraction (LVEF) and SBP. RESULTS: We analyzed 16 437 AHF patients (median = 83 years; women = 56%); 1882 received NTG (11.4%). In the whole cohort, the cumulative 30-day mortality in patients receiving NTG was higher (11.5% vs. 9.6%; unadjusted HR, 1.19; 95% CI, 1.04-1.36), but not in the PS-matched cohorts (1698 pairs of patients; 11.5% vs. 10.5%; HR, 1.10; 95% CI, 0.90-1.35). Mortality was increased in NTG-treated patients with mild congestion (HR, 2.09; 95% CI, 1.19-3.67), especially in those without hypoperfusion (HR, 2.51; 95% CI, 1.24-5.10). Interaction analysis of the PS-matched cohorts confirmed detrimental effects of NTG use in less congested patients, whereas beneficial effects were only observed in patients with decreased LVEF (<50% subgroup: HR, 0.59; 95% CI, 0.37-0.92; ≥50% subgroup: HR, 1.30; 95% CI, 0.66-2.56; P = 0.002). CONCLUSION: Phenotypical classification of AHF based on congestion/hypoperfusion at ED arrival does not identify subgroups of patients in whom IV-NTG would decrease mortality, although it could potentially be beneficial in those with LVEF of less than 50%. This hypothesis will have to be confirmed in the future. Conversely, our results suggest that IV-NTG may be harmful in patients with only mild clinical congestion.

Incidence, Clinical Characteristics, Risk Factors and Outcomes of Acute Coronary Syndrome in Patients With COVID-19: Results of the UMC-19-S1010.

BACKGROUND: There is a lack of knowledge about the real incidence of acute coronary syndrome (ACS) in patients with COVID-19, their clinical characteristics, and their prognoses. OBJECTIVE: We investigated the incidence, clinical characteristics, risk factors, and outcomes of ACS in patients with COVID-19 in the emergency department. METHODS: We retrospectively reviewed all COVID-19 patients diagnosed with ACS in 62 Spanish emergency departments between March and April 2020 (the first wave of COVID-19). We formed 2 control groups: COVID-19 patients without ACS (control A) and non-COVID-19 patients with ACS (control B). Unadjusted comparisons between cases and control subjects were performed regarding 58 characteristics and outcomes. RESULTS: We identified 110 patients with ACS in 74,814 patients with COVID-19 attending the ED (1.48% [95% confidence interval {CI} 1.21-1.78%]). This incidence was lower than that observed in non-COVID-19 patients (3.64% [95% CI 3.54-3.74%]; odds ratio [OR] 0.40 [95% CI 0.33-0.49]). The clinical characteristics of patients with COVID-19 associated with a higher risk of presenting ACS were: previous coronary artery disease, age ≥60 years, hypertension, chest pain, raised troponin, and hypoxemia. The need for hospitalization and admission to intensive care and in-hospital mortality were higher in cases than in control group A (adjusted OR [aOR] 6.36 [95% CI 1.84-22.1], aOR 4.63 [95% CI 1.88-11.4], and aOR 2.46 [95% CI 1.15-5.25]). When comparing cases with control group B, the aOR of admission to intensive care was 0.41 (95% CI 0.21-0.80), while the aOR for in-hospital mortality was 5.94 (95% CI 2.84-12.4). CONCLUSIONS: The incidence of ACS in patients with COVID-19 attending the emergency department was low, around 1.48%, but could be increased in some circumstances. Patients with COVID-19 with ACS had a worse prognosis than control subjects with higher in-hospital mortality.

Acute heart failure in subtropical climates: clinical characteristics, management, and outcomes in the Canary Islands versus continental Spain - the CANAR-ICA study results. / Características clínicas, asistenciales y evolutivas de la insuficiencia cardiaca aguda en el clima subtropical: resultados del estudio CANAR-ICA.

OBJECTIVES: To determine whether there are differences in the clinical characteristics, management, and outcome of episodes of acute heart failure (AHF) in residents of the Canary Islands, where the climate is subtropical, and episodes in continental Spain. MATERIAL AND METHODS: Cases were identified in the registry for Epidemiology of Acute Heart Failure in Emergency Departments and categorized as in the Canary Islands or continental Spain. Data for 38 demographic, baseline, clinical, and therapeutic variables were extracted. We analyzed statistics for in-hospital and 30-day mortality, long hospital stay (more than 7 days), and a composite outcome after discharge (revisits or death within 30 days). The results for island and continental patients were compared and adjusted for between-group differences. RESULTS: A total of 18 390 patients were studied, 697 islanders (3.8%) and 17 673 continental patients (96.2%). Comparisons showed that the islanders were younger; more often women; and more likely to have hypertension, diabetes, and a prior AHF episode. Their New York Heart Association functional class was also likely to be higher. However, their rates of dyslipidemia, valve disease, and functional dependence were lower, and they were also less likely to be on reninangiotensin system blockers. Although the severity of cardiac decompensation was similar in island and continental patients, the islanders received more intravenous treatments in the emergency department and were admitted less often. The adjusted risk of a long hospital stay was higher for the islanders (odds ratio [OR], 2.36; 95% CI, 1.52-3.02) but their risk for mortality and the composite outcome did not differ: in-hospital mortality, OR 0.97 (95% CI, 0.68-1.37); 30-day mortality, OR, 0.9 (95% CI, 0.67-1.27); and the post-discharge composite, OR, 1.19 (95% CI, 0.93-1.53). CONCLUSION: Baseline patient characteristics and clinical management of AHF episodes differ between the subtropical region and those in southern continental Europe. Hospitalization was required less often, but hospital stays were longer.

OBJETIVO: Investigar si existen diferencias clínicas, asistenciales y evolutivas entre los episodios de insuficiencia cardiaca aguda (ICA) desarrollados en residentes en las Islas Canarias (CAN), de clima subtropical, y en los del territorio español continental (CON). METODO: . Los pacientes con ICA incluidos en el registro EAHFE se dividieron en CAN o CON. Se recogieron 38 variables demográficas, de estado clínico basal, clínicas y terapéuticas. Se analizó la mortalidad intrahospitalaria y a los 30 días, la hospitalización prolongada (> 7 días) y el evento combinado post-alta (reconsulta o muerte a 30 días). Se compararon los pacientes CAN y CON, ajustando los resultados por las diferencias entre grupos. RESULTADOS: Se incluyeron 18.390 pacientes: CAN = 697 (3,8%), CON = 17.673 (96,2%). Tras el ajuste, los CAN eran más jóvenes, más frecuentemente mujeres, tenían más antecedentes de hipertensión, diabetes e ICA previa, y estaban en clase funcional más avanzada, pero tenían menos dislipemia, valvulopatías y dependencia funcional, y recibían menos frecuentemente inhibidores del eje renina-angiotensina. Aunque la gravedad del episodio de descompensación fue similar, los CAN recibían más tratamientos endovenosos en urgencias y se hospitalizaban menos. El riesgo ajustado de hospitalización prolongada en los CAN resultó incrementado (OR 2,36; IC 95%:1,52-3,02), pero no hubo diferencias en la mortalidad intrahospitalaria (OR 0,97; IC 95%: 0,68-1,37), a 30 días (OR 0,9; IC 95%: 0,67-1,27) o en los eventos combinados post-alta a los 30 días (OR 1,19; IC 95%: 0,93-1,53). CONCLUSIONES: Existen diferencias tanto en las características basales como en el manejo clínico de los episodios de insuficiencia cardiaca en los residentes de una región subtropical respecto a los de una zona meridional europea. Además, tienen menor necesidad de hospitalización, aunque estas son más prolongadas.

Reducing medication errors for adults in hospital settings.

BACKGROUND: Medication errors are preventable events that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of the healthcare professional or patient. Medication errors in hospitalised adults may cause harm, additional costs, and even death. OBJECTIVES: To determine the effectiveness of interventions to reduce medication errors in adults in hospital settings. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers on 16 January 2020.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) and interrupted time series (ITS) studies investigating interventions aimed at reducing medication errors in hospitalised adults, compared with usual care or other interventions. Outcome measures included adverse drug events (ADEs), potential ADEs, preventable ADEs, medication errors, mortality, morbidity, length of stay, quality of life and identified/solved discrepancies. We included any hospital setting, such as inpatient care units, outpatient care settings, and accident and emergency departments. DATA COLLECTION AND ANALYSIS: We followed the standard methodological procedures expected by Cochrane and the Effective Practice and Organisation of Care (EPOC) Group. Where necessary, we extracted and reanalysed ITS study data using piecewise linear regression, corrected for autocorrelation and seasonality, where possible.  MAIN RESULTS: We included 65 studies: 51 RCTs and 14 ITS studies, involving 110,875 participants. About half of trials gave rise to 'some concerns' for risk of bias during the randomisation process and one-third lacked blinding of outcome assessment. Most ITS studies presented low risk of bias. Most studies came from high-income countries or high-resource settings. Medication reconciliation -the process of comparing a patient's medication orders to the medications that the patient has been taking- was the most common type of intervention studied. Electronic prescribing systems, barcoding for correct administering of medications, organisational changes, feedback on medication errors, education of professionals and improved medication dispensing systems were other interventions studied. Medication reconciliation Low-certainty evidence suggests that medication reconciliation (MR) versus no-MR may reduce medication errors (odds ratio [OR] 0.55, 95% confidence interval (CI) 0.17 to 1.74; 3 studies; n=379). Compared to no-MR, MR probably reduces ADEs (OR 0.38, 95%CI 0.18 to 0.80; 3 studies, n=1336 ; moderate-certainty evidence), but has little to no effect on length of stay (mean difference (MD) -0.30 days, 95%CI -1.93 to 1.33 days; 3 studies, n=527) and quality of life (MD -1.51, 95%CI -10.04 to 7.02; 1 study, n=131).  Low-certainty evidence suggests that, compared to MR by other professionals, MR by pharmacists may reduce medication errors (OR 0.21, 95%CI 0.09 to 0.48; 8 studies, n=2648) and may increase ADEs (OR 1.34, 95%CI 0.73 to 2.44; 3 studies, n=2873). Compared to MR by other professionals, MR by pharmacists may have little to no effect on length of stay (MD -0.25, 95%CI -1.05 to 0.56; 6 studies, 3983). Moderate-certainty evidence shows that this intervention probably has little to no effect on mortality during hospitalisation (risk ratio (RR) 0.99, 95%CI 0.57 to 1.7; 2 studies, n=1000), and on readmissions at one month (RR 0.93, 95%CI 0.76 to 1.14; 2 studies, n=997); and low-certainty evidence suggests that the intervention may have little to no effect on quality of life (MD 0.00, 95%CI -14.09 to 14.09; 1 study, n=724).  Low-certainty evidence suggests that database-assisted MR conducted by pharmacists, versus unassisted MR conducted by pharmacists, may reduce potential ADEs (OR 0.26, 95%CI 0.10 to 0.64; 2 studies, n=3326), and may have no effect on length of stay (MD 1.00, 95%CI -0.17 to 2.17; 1 study, n=311).  Low-certainty evidence suggests that MR performed by trained pharmacist technicians, versus pharmacists, may have little to no difference on length of stay (MD -0.30, 95%CI -2.12 to 1.52; 1 study, n=183). However, the CI is compatible with important beneficial and detrimental effects. Low-certainty evidence suggests that MR before admission may increase the identification of discrepancies compared with MR after admission (MD 1.27, 95%CI 0.46 to 2.08; 1 study, n=307). However, the CI is compatible with important beneficial and detrimental effects. Moderate-certainty evidence shows that multimodal interventions probably increase discrepancy resolutions compared to usual care (RR 2.14, 95%CI 1.81 to 2.53; 1 study, n=487). Computerised physician order entry (CPOE)/clinical decision support systems (CDSS) Moderate-certainty evidence shows that CPOE/CDSS probably reduce medication errors compared to paper-based systems (OR 0.74, 95%CI 0.31 to 1.79; 2 studies, n=88).  Moderate-certainty evidence shows that, compared with standard CPOE/CDSS, improved CPOE/CDSS probably reduce medication errors (OR 0.85, 95%CI 0.74 to 0.97; 2 studies, n=630). Low-certainty evidence suggests that prioritised alerts provided by CPOE/CDSS may prevent ADEs compared to non-prioritised (inconsequential) alerts (MD 1.98, 95%CI 1.65 to 2.31; 1 study; participant numbers unavailable). Barcode identification of participants/medications Low-certainty evidence suggests that barcoding may reduce medication errors (OR 0.69, 95%CI 0.59 to 0.79; 2 studies, n=50,545). Reduced working hours Low-certainty evidence suggests that reduced working hours may reduce serious medication errors (RR 0.83, 95%CI 0.63 to 1.09; 1 study, n=634). However, the CI is compatible with important beneficial and detrimental effects. Feedback on prescribing errors Low-certainty evidence suggests that feedback on prescribing errors may reduce medication errors (OR 0.47, 95%CI 0.33 to 0.67; 4 studies, n=384). Dispensing system Low-certainty evidence suggests that dispensing systems in surgical wards may reduce medication errors (OR 0.61, 95%CI 0.47 to 0.79; 2 studies, n=1775). AUTHORS' CONCLUSIONS: Low- to moderate-certainty evidence suggests that, compared to usual care, medication reconciliation, CPOE/CDSS, barcoding, feedback and dispensing systems in surgical wards may reduce medication errors and ADEs. However, the results are imprecise for some outcomes related to medication reconciliation and CPOE/CDSS. The evidence for other interventions is very uncertain. Powered and methodologically sound studies are needed to address the identified evidence gaps. Innovative, synergistic strategies -including those that involve patients- should also be evaluated.

Outcomes of patients with heart failure with preserved ejection fraction discharged on treatment with neurohormonal antagonists after an episode of decompensation.

AIMS: To analyze the frequency with which patients with heart failure with preserved ejection fraction (HFpEF) discharged after an acute heart failure (AHF) episode are treated with antineurohormonal drugs (ANHD), the variables related to ANHD prescription and their relationship with outcomes. METHODS: We included consecutive HFpEF patients (left ventricular ejection fraction ≥50%) discharged after an AHF episode from 45 Spanish hospitals whose chronic medications and treatment at discharge were available. Patients were classified according to whether they were discharged with or without ANHD, including beta-blockers (BB), renin-angiotensin-aldosterone-system inhibitors (RAASi) and mineralcorticosteroid-receptor antagonists (MRA). Co-primary outcomes consisted of 1-year all-cause mortality and 90-day combined adverse event (revisit to emergency department -ED-, hospitalization due to AHF or all-cause death). Secondary outcomes were 90-day adverse events taken individually. Adjusted associations of ANHD treatment with outcomes were calculated. RESULTS: We analyzed 3,305 patients with HFpEF (median age: 83, 60% women), 2,312 (70%) discharged with ANHD. The ANHD most frequently prescribed was BB (45.8%). The 1-year mortality was 26.9% (adjusted HR for ANHD patients:1.17, 95%CI=0.98-1.38) and the 90-day combined adverse event was 54.4% (HR=1.14, 95%CI=0.99-1.31). ED revisit was significantly increased by ANHD (HR=1.15, 95%CI=1.01-1.32). MRA and BB were associated with worse results in some co-primary or secondary endpoints, while RAASi (alone) reduced 90-day hospitalization (HR=0.73, 98%CI=0.56-0.96). CONCLUSION: 70% of HFpEF patients are discharged with ANHD after an AHF episode. ANHD do not seem to reduce mortality or adverse events in HFpEF patients, only RAASi could provide some benefits, reducing the risk of hospitalization for AHF.
