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.

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.

Factors associated with in-hospital mortality and adverse outcomes during the vulnerable post-discharge phase after the first episode of acute heart failure: results of the NOVICA-2 study.

OBJECTIVE: To identify patients at risk of in-hospital mortality and adverse outcomes during the vulnerable post-discharge period after the first acute heart failure episode (de novo AHF) attended at the emergency department. METHODS: This is a secondary review of de novo AHF patients included in the prospective, multicentre EAHFE (Epidemiology of Acute Heart Failure in Emergency Department) Registry. We included consecutive patients with de novo AHF, for whom 29 independent variables were recorded. The outcomes were in-hospital all-cause mortality and all-cause mortality and readmission due to AHF within 90 days post-discharge. A follow-up check was made by reviewing the hospital medical records and/or by phone. RESULTS: We included 3422 patients. The mean age was 80 years, 52.1% were women. The in-hospital mortality was 6.9% and was independently associated with dementia (OR = 2.25, 95% CI = 1.62-3.14), active neoplasia (1.97, 1.41-2.76), functional dependence (1.58, 1.02-2.43), chronic treatment with beta-blockers (0.62, 0.44-0.86) and severity of decompensation (6.38, 2.86-14.26 for high-/very high-risk patients). The 90-day post-discharge combined endpoint was observed in 19.3% of patients and was independently associated with hypertension (HR = 1.40, 1.11-1.76), chronic renal insufficiency (1.23, 1.01-1.49), heart valve disease (1.24, 1.01-1.51), chronic obstructive pulmonary disease (1.22, 1.01-1.48), NYHA 3-4 at baseline (1.40, 1.12-1.74) and severity of decompensation (1.23, 1.01-1.50; and 1.64, 1.20-2.25; for intermediate and high-/very high-risk patients, respectively), with different risk factors for 90-day post-discharge mortality or rehospitalisation. CONCLUSIONS: The severity of decompensation and some baseline characteristics identified de novo AHF patients at increased risk of developing adverse outcomes during hospitalisation and the vulnerable post-discharge phase, without significant differences in these risk factors according to patient age at de novo AHF presentation.

Worsening renal function during an episode of acute heart failure and its relation to short- and long-term mortality: associated factors in the Epidemiology of Acute Heart Failure in Emergency Departments- Worsening Renal Function study. / Factores asociados con el empeoramiento de la función renal durante un episodio de insuficiencia cardiaca aguda y su relación con la mortalidad a corto y largo plazo: estudio EAHFE - EFRICA.

OBJECTIVES: To identify factors associated with worsening renal function (WRF) and explore associations with higher mortality in patients with acute heart failure (AHF). MATERIAL AND METHODS: Seven emergency departments (EDs) in the EAHFE-EFRICA study (Spanish acronym for Epidemiology of AHF in EDs - WRF in AHF) consecutively included patients with AHF and creatinine levels determined in the ED and between 24 and 48 hours later. Patients with WRF were identified by an increase in creatinine level of 0.3 mg/dL or more. Forty-seven clinical characteristics were explored to identify those associated with WRF. To analyze for 30-day all-cause mortality we calculated odds ratios (ORs). To analyze mortality at the end of follow-up and by trimester, adjusted for between-group differences, we calculated hazard ratios (HRs). The data were analyzed by subgroups according to age, sex, baseline creatinine levels, AHF type, and risk group. RESULTS: A total of 1627 patients were included. The subgroup of 220 (13.5%) with WRF were older, had higher systolic blood pressure, were more often treated with morphine, and had chronic renal failure; there was also a higher rate of hypertensive crisis as the trigger for AHF in patients with WRF. However, only chronic renal failure was independently associated with WRF (adjusted OR, 1.695; 95% CI, 1.264-2.273). The rate of 30-day mortality was 13.1% overall but higher in patients with WRF (20.9% vs 11.8% in patients without WRF; adjusted OR, 1.793; 95% CI, 1.207-2.664). Accumulated mortality at 18 months (average follow-up time, 14 mo/patient) was 40.0% overall but higher in patients with WRF (adjusted HR, 1.275; 95% CI, 1.018-1.598). Increased risk was greater in the first trimester. Subgroup analyses revealed no differences. CONCLUSION: AHF with WRF in the first 48 hours after ED care is associated with higher mortality, especially in the first trimester after the emergency.

OBJETIVO: Identificar los factores asociados con el empeoramiento de la función renal (EFR) y si este se asocia a mayor mortalidad en pacientes que presentan un episodio de insuficiencia cardiaca aguda (ICA). METODO: Participaron 7 servicios de urgencias (SU) que incluyeron consecutivamente pacientes con ICA con determinación de creatinina en urgencias y a las 24-48 horas, y se identificaron aquellos con EFR (incremento de creatinina $ 0,3 mg/dL). Entre 47 características clínicas, se identificó las asociadas a EFR. Se investigó la mortalidad por cualquier causa a 30 días (OR) y al final del seguimiento (HR), esta última global y por periodos trimestrales, que se ajustó por las diferencias entre grupos. Se analizaron subgrupos según edad, sexo, creatinina basal, tipo de ICA y grupo de riesgo. RESULTADOS: Se incluyeron 1.627 pacientes, 220 (13,5%) con EFR, los cuales presentaban mayor edad, presión arterial sistólica, crisis hipertensiva como precipitante, tratamiento con morfina e insuficiencia renal crónica, aunque solo esta última se asoció independientemente a EFR (ORajustada = 1,695, IC 95% = 1,264-2,273). La mortalidad a 30 días fue de 13,1% (mayor en pacientes con EFR: 20,9% vs 11,8%, ORajustada = 1,793, IC 95% = 1,207-2,664) y la mortalidad acumulada a 18 meses (tiempo medio de seguimiento 14 meses/paciente) fue del 40,0% (mayor en pacientes con EFR: HRajustada = 1,275, IC 95% = 1,018-1,598). Este incremento de riesgo fue durante el primer trimestre. El análisis de subgrupos no mostró diferencias. CONCLUSIONES: La ICA con EFR en las primeras 48 horas posteriores a la atención en el SU se asocia a mayor mortalidad, que se concentra durante el primer trimestre.

Iron deficiency and safety of ferric carboxymaltose in patients with acute heart failure. AHF-ID study.

INTRODUCTION: The presence of iron deficiency (ID) in patients with acute heart failure (AHF) is high. There are few studies on the characteristics of these patients and the safety of ferric carboxymaltose administration (FCM). OBJECTIVE: Study the differences among patients with AHF based on the presence and type of ID as well as the safety of FCM administration in these patients. METHOD: The AHF-ID study is a multicentre, analytical, prospective follow-up cohort including patients admitted to six Spanish hospitals for AHF. ID was defined as serum ferritin <100 µg/L (group A) or ferritin 100-299 µg/L with a TSAT <20% (group B). In cases receiving FCM the appearance of adverse events was analysed. Adjusted Cox regression was used to determine the association with 30-days reattendance for AHF after discharge. RESULTS: A total of 221 patients were recruited; 191 (86.4%) presented ID, 121 (63.4%) group A and 70 (36.6%) group B. There were scarce differences between the groups analysed. No differences were found in 30-days reattendance for AHF. FCM was administered to 158 (71.5%) patients, with 8 (5.1%) presenting adverse events, the most frequent being digestive alterations. Treatment was not discontinued in any case. CONCLUSIONS: There are scarce differences between the presence and the type of ID in patients with AHF. The administration of FCM in patients with ID and AHF is safe.

The CRAS-EAHFE study: Characteristics and prognosis of acute heart failure episodes with cardiorenal-anaemia syndrome at the emergency department.

BACKGROUND: The coexistence of other comorbidities confers poor outcomes in patients with acute heart failure. Our aim was to determine the characteristics of patients with acute heart failure and cardiorenal anaemia syndrome and the relationship between renal dysfunction and anaemia, alone or combined as cardiorenal anaemia syndrome, on short-term outcomes. METHODS: We analysed the Epidemiology of Acute Heart Failure in Emergency Departments registry (cohort of patients with acute heart failure in Spanish emergency departments). Renal dysfunction was defined by an estimated glomerular filtration rate <60 ml/min/m2, anaemia by haemoglobin values <12/<13 g/dl in women/men, and cardiorenal anaemia syndrome as the presence of both. Comparisons were made according to cardiorenal-anaemia syndrome positive (CRAS+) with respect to the rest of patients (CRAS-) and according the presence of renal dysfunction (RD+) and anaemia (A+), (alone, RD+/A-, RD-/A+) or in combination (RD+/A+; i.e. CRAS+) with respect to patients without renal dysfunction and anaemia (RD-/A-). The primary outcome was 30-day mortality, and the secondary outcomes were need for admission, prolonged hospitalisation (>10 days), in-hospital mortality during the index event, and reconsultation and the combination of 30-day post-discharge reconsultation/death. These short-term outcomes were compared and adjusted for differences among groups. RESULTS: Of the 13,307 patients analysed, CRAS+ (36.4%) was associated with older age, multiple comorbidities, chronic use of loop diuretics, oedemas and hypotension. The 30-day mortality in CRAS+ was greater than in CRAS- (hazard ratio = 1.46, 95% confidence interval = 1.26-1.68) and RD-/A- (hazard ratio = 1.83, 95% confidence interval = 1.46-2.28) control groups. The mortality level was also higher in RD+/A- (hazard ratio = 1.40, 95% confidence interval = 1.10-1.78) and higher, but not statistically significant, in RD-/A+ (hazard ratio = 1.28, 95% confidence interval = 0.99-1.63) with respect to RD-/A-. All of the secondary outcomes, when related to CRAS- and RD-/A- control groups, were worse for CRAS+ and to a lesser extent, RD+/A-, being more rarely observed in RD-/A+. CONCLUSIONS: Cardiorenal anaemia syndrome in acute heart failure is related to greater mortality and worse short-term outcomes, and the impact of renal dysfunction and anaemia seems to be additive.

High-sensitivity cardiac troponin T 30 days all-come mortality in patients with acute heart failure. A Propensity Score-Matching Analysis Based on the EAHFE Registry. TROPICA4 Study.

BACKGROUND: Acute heart failure (AHF) patients with high troponin levels have a worse prognosis. High-sensitive troponin T (hs-TnT) has been used as a tool to stratify prognosis in many scales but always as a qualitative and not as a quantitative variable. OBJECTIVES: The main objective of this study was to determine the best hs-TnT cut-off for prediction of 30-day all-cause mortality. METHODS: The EAHFE registry, a prospective follow-up cohort of patients with AHF, was analysed. We performed a propensity score analysis of the optimal hs-TnT cut-off point previously determined by receiver operating characteristic (ROC) curve analysis. RESULTS: Of the 13 791 patients in the EAHFE cohort, we analysed 3190 patients in whom hs-TnT determination was available. The area under the ROC curve for 30-day all-cause mortality was 0.70 (CI95% 0.68 to 0.71; P < .001), establishing an optimal cut-off of hs-TnT of 35 ng/L. The sensitivity and specificity of this cut-off were 76.2 and 55.5%, respectively, with a negative predictive value (NPV) of 95.3%. A propensity score was made with 34 variables showing differences based on the cut-off of 35 ng/L for hs-TnT. In the analysis of the population obtained with the propensity score, patients with hs-TnT > 35 ng/L showed a greater 30-day all-cause mortality, with a HR of 2.95 (CI95% 1.83-4.75; P < .001). External validation reported similar results. CONCLUSIONS: An hs-TnT value of 35 ng/L is an adequate cut-off to evaluate the prediction of 30-day all-cause mortality with a NPV of 95.3%.

Acute heart failure and adverse events associated with the presence of renal dysfunction and hyperkalaemia. EAHFE- renal dysfunction and hyperkalaemia.

OBJECTIVE: To study the outcomes of patients with acute heart failure (AHF) presenting renal dysfunction (RD) or hyperkalaemia (Hk) alone or in combination. METHOD: We analysed the data of the EAHFE registry, a multicentre, non interventionist cohort with prospective follow-up of patients with AHF. Four groups were defined based on the presence or not of RD or Hk alone or in combination. The primary endpoint was 30-day all-cause mortality. RESULTS: A total of 11,935 of the 13,791 patients included in the EAHFE registry were analysed. Of these, 5088 (42.6%) did not have RD or Hk (NoRD-NoHk), 150 (1.3%) had no RD but had Hk (NoRD-Hk), 6012 (50.4%) had RD but not Hk (RD-NoHk) and 685 (5.7%) had both RD and Hk (RD-Hk). Thirty-day all-cause mortality was greatest in the RD-Hk group with an adjusted Hazard Ratio (HR) of 2.44 (confidence interval 95% [CI95%] 1.67-3.55; p < 0.001) and in the RD-NoHk group with an adjusted HR of 1.34 (CI95% 1.04-1.71; p = 0.022). There were no significant differences in in-hospital mortality and reconsultation at 30 days for HF. For the combined endpoint of 30-day all-cause mortality the adjusted HR was 1.33 (CI95% 1.04-1.70); (p = 0.021) for the RD-Hk group. CONCLUSIONS: The association of 30-day all-cause mortality with the presence of RD and Hk in patients presenting AHF at admission is greater than in those without this combination.

Effect of risk of malnutrition on 30-day mortality among older patients with acute heart failure in Emergency Departments.

BACKGROUND: Little is known about the prevalence and impact of risk of malnutrition on short-term mortality among seniors presenting with acute heart failure (AHF) in emergency setting. The objective was to determine the impact of risk of malnutrition on 30-day mortality risk among older patients who attended in Emergency Departments (EDs) for AHF. MATERIAL AND METHODS: We performed a secondary analysis of the OAK-3 Registry including all consecutive patients ≥65 years attending in 16 Spanish EDs for AHF. Risk of malnutrition was defined by the Mini Nutritional Assessment Short Form (MNA-SF) < 12 points. Unadjusted and adjusted logistic regression models were used to assess the association between risk of malnutrition and 30-day mortality. RESULTS: We included 749 patients (mean age: 85 (SD 6); 55.8% females). Risk of malnutrition was observed in 594 (79.3%) patients. The rate of 30-day mortality was 8.8%. After adjusting for MEESSI-AHF risk score clinical categories (model 1) and after adding all variables showing a significantly different distribution among groups (model 2), the risk of malnutrition was an independent factor associated with 30-day mortality (adjusted OR by model 1 = 3.4; 95%CI 1.2-9.7; p = .020 and adjusted OR by model 2 = 3.1; 95%CI 1.1-9.0; p = .033) compared to normal nutritional status. CONCLUSIONS: The risk of malnutrition assessed by the MNA-SF is associated with 30-day mortality in older patients with AHF who were attended in EDs. Routine screening of risk of malnutrition may help emergency physicians in decision-making and establishing a care plan.

Characteristics and prognosis of patients with acute heart failure without troponin determination: The EAHFE-TROPICA3 study.

BACKGROUND: The absence of cardiac troponin (cTn) determination in an episode of acute heart failure (AHF) is frequent. The characteristics of these patients are not well known; nor is it known whether they have a better prognosis than patients in whom cTn is determined. AIM: The objective of the EAHFE-TROPICA3 study was to analyse the characteristics of patients consulting for AHF in whom cTn was not determined (nocTn), and to evaluate the relationship of cTn determination (wcTn) with patient outcomes. METHODS: This was an analysis of the multipurpose prospective EAHFE registry of patients with AHF consulting at the emergency departments of 34 Spanish hospitals. RESULTS: Data from 8850 patients with AHF were analysed; cTn was not determined in 4216 of these patients (47.6%), who had a lower prevalence of ischaemic heart disease, more frequent use of loop diuretics at baseline, a greater rate of oedema in the acute episode, more frequent history of heart failure, and less use of angiotensin-converting enzyme inhibitors or aldosterone receptor antagonists and beta-blockers at baseline. Compared with the wcTn group, the nocTn group had the same in-hospital mortality (adjusted odds ratio [OR] 1.21, 95% confidence interval [CI] 0.98-1.50), mortality at 30 days (adjusted OR 1.07, 95% CI 0.90-1.28) and reconsultation at 30 days (adjusted OR 0.90, 95% CI 0.80-1.02). CONCLUSIONS: Patients presenting with AHF with and without cTn determination have different characteristics. These differences are not related to a better prognosis.

The role of atrial fibrillation in the short-term outcomes of patients with acute heart failure.

AIMS: To investigate whether the presence of atrial fibrillation (AF) is independently associated with adverse short-term outcomes in patients diagnosed with acute heart failure (AHF) in the emergency department (ED). METHODS: We performed a secondary analysis of patients included in the EAHFE registries 4&5. Patients were divided by the presence of sinus rhythm (SR) or AF at ED arrival. The primary outcome was 30-day all-cause mortality. Secondary outcomes included the 30-day post-discharge combined endpoint of ED revisit or hospitalisation due to AHF and all-cause mortality. We recorded 54 independent variables that can affect outcomes. Cox regression was used to investigate adjusted significant associations between AF and outcomes. Analyses were repeated according to whether AF was previously known and whether AF was considered responsible for the AHF episode. RESULTS: We analysed 6045 ED visits (mean age 80.4 years, 55.9% women), 3644 (60.3%) with AF. The cumulative 30-day mortality was 9.4%, and the adverse combined endpoint (ACE) was 25.9% (ED revisit with and without hospitalisation were 16.5 and 8.9% and death occurred in 4.7%). No differences were found in outcomes of AHF patients with SR and AF, and among the latter group, no differences were found depending on whether AF was considered responsible for the AHF episode. Patients with previously known AF had significantly lower 30-day mortality and higher post-discharge ACE rates, although these differences disappeared after adjustment for confounders HR 0.782, 95% CI 0.590-1.037, p = 0.087; and HR 1.131, 95% CI 0.924-1.385, p = 0.234). CONCLUSION: The coexistence of AF does not impact the short-term outcomes of patients diagnosed with AHF in the ED.

EAHFE - TROPICA2 study. Prognostic value of troponin in patients with acute heart failure treated in Spanish hospital emergency departments.

OBJECTIVE: Evaluate the use of different cardiac troponin (cTn) immunoassays and the prognostic value of increased cTn values in patients diagnosed with acute heart failure (AHF) in the emergency department (ED). METHOD: The epidemiology acute heart failure emergency-TROPonin in acute heart failure2 (EAHFE-TROPICA2) is a retrospective study including patients with AHF admitted in 34 Spanish EDs with cTn values determined in the ED. We studied the prevalence of elevated troponin (value above the established reference limit) for the different types of troponin. We also assessed crude and adjusted primary (1-year all-cause death) and secondary (30 d ED revisit due to AHF) outcomes for every type of cTn and different magnitudes of troponin elevation. RESULTS: We analysed 4705 episodes of AHF. Troponin was elevated in 48.4% of the cases (25.3% in cTnI, 37.9% in cTnT and 82.2% in hs-cTnT). Mortality at one year was higher in patients with elevated troponin (adjusted HR 1.61; CI 95% 1.38-1.88) regardless of the type of cTn determined. Elevated troponin was not related to ED revisit within 30 d after discharge (1.01; 0.87-1.19). CONCLUSIONS: The use of conventional troponin in the ED is useful to predict one-year mortality in patients with AHF. Highly sensitive cTnT (hs-cTnT) elevations less than double the reference value have no impact on patient outcome.

Neumonía asociada al ámbito sanitario (NAAS) / No disponible

Propósito de esta revisión: Recientemente se ha propuesto una nueva categoría de neumonía que engloba a aquellos pacientes con un contacto estrecho con el ámbito sanitario, llamada neumonía asociada al sistema sanitario (NAAS). El propósito de este capítulo es revisar los criterios de NAAS, la epidemiología, microorganismos causales y su susceptibilidad antibiótica, diagnóstico, tratamiento, pronóstico y prevención de la NAAS. Hallazgos recientes: La incidencia de NAAS en pacientes que requieren hospitalización oscila entre el 17 y el 67% según los diversos estudios. La hospitalización en los 90 días previos a la neumonía, recibir hemodiálisis o vivir en un centro sociosanitario son los criterios más frecuentes de relación con el ámbito sanitario. Comparados con la neumonía comunitaria, los pacientes con NAAS tienen una edad más avanzada, presentan más comorbilidades asociadas, mayor riesgo de neumonía aspirativa y de neumonía por gérmenes multirresistentes. Estos pacientes presentan más frecuentemente una antibioterapia inicial inapropiada, mayor tasa de mortalidad y estancias hospitalarias más prolongadas. Conclusiones: Muchos de los pacientes hospitalizados desde el servicio de urgencias tienen NAAS. Es importante identificar los pacientes con neumonía espirativa y aquellos con mayor riesgo de infección por microorganismos multirresistentes, para individualizar el tratamiento antibiótico (AU)

Purpose of review: Pneumonia developing before hospital admission in patients in close contact with the health system was recently termed "healthcare-associated pneumonia" (HCAP). We focus in the recent literature concerning the epidemiology, causative organisms, antibiotic susceptibilities, and outcomes of and empirical antibiotic therapy for this condition. Recent findings: The reported incidence of HCAP among patients requiring hospitalization for pneumonia ranges from 17% to 67%. Hospitalization with in 90 days before pneumonia, attending a dialysis clinic and residing in a nursing home were the most common criteria for HCAP. Compared with patients with community-acquired pneumonia, those with HCAP are older, have greater co-morbidity, and are more likely to have aspiration pneumonia and pneumonia caused by antibiotic-resistant pathogens. Patients with HCAP also more frequently initially receive an inappropriate antibiotic therapy, have higher case fatality rates and have longer hospital stay. Conclusions: Many patients hospitalized with pneumonia via the emergency department haveHCAP. Physicians should identify patients at increased risk of aspiration pneumonia or infection by multidrug-resistant pathogens to promote a targeted approach when selecting initial antibiotic therapy (AU)
