Healthcare risk stratification model for emergency departments based on drugs, income and comorbidities: the DICER-score.

BACKGROUND: During the last decade, the progressive increase in age and associated chronic comorbidities and polypharmacy. However, assessments of the risk of emergency department (ED) revisiting published to date often neglect patients' pharmacotherapy plans, thus overseeing the Drug-related problems (DRP) risks associated with the therapy burden. The aim of this study is to develop a predictive model for ED revisit, hospital admission, and mortality based on patient's characteristics and pharmacotherapy. METHODS: Retrospective cohort study including adult patients visited in the ED (triage 1, 2, or 3) of multiple hospitals in Catalonia (Spain) during 2019. The primary endpoint was a composite of ED visits, hospital admission, or mortality 30 days after ED discharge. The study population was randomly split into a model development (60%) and validation (40%) datasets. The model included age, sex, income level, comorbidity burden, measured with the Adjusted Morbidity Groups (GMA), and number of medications. Forty-four medication groups, associated with medication-related health problems, were assessed using ATC codes. To assess the performance of the different variables, logistic regression was used to build multivariate models for ED revisits. The models were created using a "stepwise-forward" approach based on the Bayesian Information Criterion (BIC). Area under the curve of the receiving operating characteristics (AUCROC) curve for the primary endpoint was calculated. RESULTS: 851.649 patients were included; 134.560 (15.8%) revisited the ED within 30 days from discharge, 15.2% were hospitalized and 9.1% died within 30 days from discharge. Four factors (sex, age, GMA, and income level) and 30 ATC groups were identified as risk factors and combined into a final score. The model showed an AUCROC values of 0.720 (95%CI:0.718-0.721) in the development cohort and 0.719 (95%CI.0.717-0.721) in the validation cohort. Three risk categories were generated, with the following scores and estimated risks: low risk: 18.3%; intermediate risk: 40.0%; and high risk: 62.6%. CONCLUSION: The DICER score allows identifying patients at high risk for ED revisit within 30 days based on sociodemographic, clinical, and pharmacotherapeutic characteristics, being a valuable tool to prioritize interventions on discharge.

Frailty and mortality: Utility of Frail-VIG index in ED short-stay units for older adults.

BACKGROUND: Frailty assessment allows the identification of patients at risk of death. The aim here was to study the ability of Frail-VIG Index (FI-VIG) in order to discriminate frailty groups of older adults and garner its correlation with mortality in an Emergency-Department Short-Stay Unit (ED-SSU). METHODS: Our observational, single-center, prospective study consecutively included patients over 65-years-old admitted between March 1, 2021, and April 30, 2021. RESULTS: 302 patients were included (56 % women), mean age 83 ± 8 years, and 39.1 % of them had a functional disability whilst 16.5 % of them had dementia. A total of 174 patients (58 %) met the frailty criteria (FI-VIG ≥ 0.2): 111 (63.8 %) had mild frailty (FI-VIG 0.2-0.36), 52 (29.9 %) had moderate frailty (FI-VIG 0.36-0.55), and 11 (6.3 %) had advanced frailty (FI-VIG > 0.55). Mortality at 30 days, 6 months, and 1 year was analyzed: no frailty was 6.3 %, 10.8 %, and 12.5 %, respectively; mild frailty was 10.8 %, 22.5 %, and 22.5 %, respectively; moderate frailty was 25 %, 34.6 %, and 42.3 %, respectively; advanced frailty was 36.4 %, 54.5 %, and 3.6 %, respectively. This shows the significant differences between the groups (1-year mortality p < 0.001). Mild frailty vs. non-frail HR was 2.47 (95 %CI 1.12-5.46), moderate frailty vs. non-frail HR was 6.93 (95 %CI 3.16-15.23), and advanced frailty vs. non-frail HR was 11.29 (95 %CI 3.54-36.03). The mean test time was 7 min. CONCLUSIONS: There was a strong correlation between frailty degree and mortality at 1, 6, and 12 months. FI-VIG is fast and easy-to-use in this setting. It is routine implementation in ED-SSUs could enable early risk stratification.

PREDICTION OF MULTIDRUG-RESISTANT BACTERIA IN URINARY TRACT INFECTIONS IN THE EMERGENCY DEPARTMENT.

BACKGROUND: Urinary tract infections (UTI) due to multidrug-resistant bacteria are a frequent reason for visiting the emergency department (ED). OBJECTIVES: The aim of this study was to evaluate the applicability of a predictive model of infection by multidrug-resistant microorganisms in UTIs treated in an ED. METHODS: This is a retrospective observational study. Adult patients admitted to an ED with a diagnosis of UTI and positive urine culture were included. The main objective was to evaluate the area under the curve of the receiver operating characteristic (AUC-ROC), the scale proposed by González-del-Castillo, considering infection by a resistant pathogen as the dependent variable and the scale score of the predictive model used as the independent variable. RESULTS: The study included 414 patients with UTIs, 125 (30.2%) of which were caused by multidrug-resistant microorganisms. A total of 38.4% of patients were treated with antibiotics during the previous 3 months and a multidrug-resistant pathogen was isolated from 10.4% of the total during the previous 6 months. The AUC-ROC of the scale for predicting UTIs due to multidrug-resistant microorganisms was 0.79 (95% confidence interval 0.76-0.83), the optimal cut-off point being 9 points, with a sensitivity of 76.8% and a specificity of 71.6%. CONCLUSIONS: The use of the predictive model evaluated is a useful tool in real clinical practice to improve the success of empirical treatment of patients presenting to the ED with a diagnosis of UTI and positive urine culture pending identification.

Pharmacist care in hospital emergency departments: a consensus paper from the Spanish hospital pharmacy and emergency medicine associations. / Atención farmacéutica en los servicios de urgencias: documento de posicionamiento de la Sociedad Española de Farmacia Hospitalaria (SEFH) y la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES).

OBJECTIVES: To draft a list of actions and quality indicators for pharmacist care in hospital emergency departments, based on consensus among a panel of experts regarding which actions to prioritize in this setting. MATERIAL AND METHODS: A panel of experts from the Spanish Society of Hospital Pharmacy (SEFH) and the Spanish Society of Emergency Medicine (SEMES) evaluated a preliminary list of potential actions and quality of care indicators. The experts used a questionnaire to assess the proposals on the basis of available evidence. In the first round, each expert individually assessed the importance of each proposed action based on 4 dimensions: evidence base, impact on clinical response and patient safety, ease of implementation, and priority. In the second round the experts attended a virtual meeting to reach consensus on a revised list of proposals; suggestions and comments that had been made anonymously in the first round were included. The group then prioritized each action as basic, intermediate, or advanced. RESULTS: The experts evaluated a total of 26 potential actions and associated quality indicators. No items were eliminated in the analysis of scores and comments from the first round. After the second round, 25 actions survived. Nine were considered basic, 10 intermediate, and 6 advanced. CONCLUSION: The expert panel's list of pharmacist actions and care quality indicators provides a basis for developing a pharmacist care program in Spanish emergency departments on 3 levels of priority. The list can serve as a guide to pharmacists, managers, physicians, and nurses involved in the effort to improve drug therapy in this hospital setting.

OBJETIVO: Desarrollar un conjunto de actividades e indicadores de atención farmacéutica en los servicios de urgencias hospitalarios mediante un consenso colectivo de un panel de expertos que permita priorizar las actividades a realizar por los farmacéuticos en estas unidades. METODO: Un comité formado por miembros de la Sociedad Española de Farmacia Hospitalaria (SEFH) y de la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES) evaluó una propuesta inicial de actividades e indicadores potenciales, basados en la evidencia científica disponible, en formato de cuestionario. En una primera ronda, cada uno de los expertos del panel clasificó de forma individual la relevancia de cada una de las actividades propuestas en cuatro dimensiones: evidencia científica, impacto en la respuesta clínica y seguridad para el paciente, facilidad de implementación y grado de prioridad. La segunda ronda se realizó mediante una reunión grupal de forma virtual, a partir del cuestionario modificado de acuerdo con las sugerencias planteadas, así como los comentarios vertidos por los participantes del panel de forma anónima. En esta ronda, cada actividad fue clasificada por consenso como básica, intermedia o avanzada en función del grado de prioridad de implantación considerado por el grupo de expertos. RESULTADOS: Se propusieron un total de 26 potenciales actividades a los expertos, con indicadores asociados. Tras el análisis de las puntuaciones y los comentarios realizados en la primera ronda, no se eliminó ninguna de las actividades propuestas. Tras la segunda ronda, se mantuvieron 25 actividades, de las cuales se puntuaron 9 como actividades básicas, 10 actividades como intermedias y 6 actividades como avanzadas. CONCLUSIONES: El desarrollo del conjunto de actividades e indicadores de atención farmacéutica en urgencias, priorizados por grado de relevancia para la unidad, es la base para el desarrollo de esta cartera de servicios en los hospitales españoles, y sirve como guía tanto para farmacéuticos como para gestores, médicos y enfermeros de la unidad a fin de mejorar la farmacoterapia los pacientes atendidos en los servicios de urgencias.

[Translated article] Usefulness of ICD-10 diagnostic triggers to identify adverse drug events in emergency care.

OBJECTIVES: To assess the usefulness of a tool based on ICD-10 diagnostic codes to identify patients who consult an emergency department for adverse drug events (ADE). METHODS: Prospective observational study, in which patients discharged from an emergency department during May to August 2022 with a diagnosis coded with one of the 27 ICD-10 diagnoses considered as triggers were included. ADE confirmation was carried out by analyzing drugs prescribed prior to admission, and through a discussion among experts and a phone interview with patients after hospital discharge. RESULTS: 1143 patients with trigger diagnoses were evaluated, of which 310 (27.1%) corresponded to patients whose emergency visit was attributed to an ADE. A 58.4% of ADE consultations were found with three diagnostic codes: K59.0-Constipation (n = 87; 28.1%), I16.9-Hypertensive Crisis (n = 72; 23.2%) and I95.1-Orthostatic hypotension (n = 22; 7.1%). The diagnoses with the highest degree of association with consultations attributed to ADE were E16.2-Hypoglycemia, unspecified (73.7%) and E11.65-Type 2 diabetes mellitus with hyperglycemia (71.4%), while diagnoses D62-Acute posthemorrhagic anemia and I74.3-Embolism and thrombosis of arteries of the lower limbs were not attributed to any case of ADE. CONCLUSIONS: The ICD-10 codes associated with trigger diagnoses are a useful tool to identify patients who consult the emergency services with ADE and could be used to apply secondary prevention programs to avoid new consultations to the health care system.

Association of sex and age and delay predictors on the time of primary angioplasty activation for myocardial infarction patients in an emergency department.

BACKGROUND: Time between Emergency Department (ED) and ST-segment elevation acute myocardial infarction (STEMI) activation time is a good indicator of ED quality. STEMI delays are of particular importance in some subgroups, such as women and the elderly. OBJECTIVE: To determine the association of sex and age with activation time in STEMI patients admitted to the ED. METHODS: An observational retrospective study was conducted including all patients admitted to the ED activated as a STEMI. The main variable was activation time. To evaluate the independent predictors of activation time, a multivariate logistic regression analysis was carried out, variables were sex, age, sex and age combined, chest pain, ST elevation in the electrocardiogram, and first medical contact (FMC) at the hospital's ED. RESULTS: A total of 330 patients were included. They were classified by sex: 23.9% (78) women and 76.1% (249) men; and age: 51.1% (167) <65 yo and 48.9% (160) ≥65 yo. Women and elderly patients exhibited a more atypical presentation. Multivariate analysis shows that showed that elderly age (OR=1.976 95%; CI=1.257-3.104; p = 0.003) and FMC prior to attending the ED (OR=1.762; 95% CI=1.117-2.779; p = 0.015) were associated with a longer activation time. Women older than 65 years old showed the longest activation time. CONCLUSION: STEMI delays are longer in women and the elderly with atypical presentation. Age ≥65 and FMC outside the ED were associated with an increase in the activation time. This highlights the need to develop strategies to improve activation time for these specific patient groups.

Anticholinergic burden and revisit risk in frail patients with pharmacological sleepiness.

OBJECTIVE: Drug-induced sleepiness is a frequent cause of emergency department (ED) visits for frail patients. The aim of this study was to assess the impact of anticholinergic burden on 90-day revisitation risk for frail patients who visit the ED due to drug-induced sleepiness. METHODS: This was a retrospective study in which patients treated at a fragility care area of an ED who sought consultation for drug-associated sleepiness from June 2020 to June 2021 were included. To evaluate the 90-day revisitation risk factors, a multivariate analysis was performed, including those factors with a p<0.200 from a previous univariate model. A Cox regression model was performed to assess the impact of a high burden on the time until 90-day ED revisitation. RESULTS: One hundred and forty-eight patients were included (mean age 80.7±12.3 years). The median number of drugs that patients were currently on at emergency admission was eight (range 2-19), while at hospital discharge it was nine (range 2-20), with the median number of central nervous system (CNS) depressant drugs on admission being three (range 1-6). Thirty-five (23.6%) patients revisited the ED 90 days after discharge for sleepiness or agitation. In the multivariate model, a significant association was observed between a high anticholinergic burden during treatment at discharge (OR 3.74, 95% CI 1.36 to 9.71), chronic kidney disease (OR 2.87, 95% CI 1.19 to 6.81), and the risk of 90-day revisitation. Patients with high anticholinergic burden had a shorter time to revisit than those with medium or low anticholinergic burden (HR 1.96, 95% CI 1.05 to 3.99). CONCLUSIONS: Patients with pharmacological sleepiness and a high anticholinergic burden in their chronic treatment carry a greater risk of revisitation to EDs, and should be considered candidates for specific interventions after visiting these units.

Cefepime Dosing Requirements in Elderly Patients Attended in the Emergency Rooms.

OBJECTIVE: This study aimed to assess the probability of reaching an adequate pharmacokinetic/pharmacodynamic (pK/pD) index for different cefepime dosages in frail patients with bacteremia treated in the emergency room. METHODS: Simulation study based on Gram-negative bacterial strains that cause bacteremia. The probability of reaching a time above the minimum inhibitory concentration (MIC) at 50% and 100% dosing intervals (fT > 50 and fT > 80% MIC) was assessed for two different renal clearance intervals. RESULTS: One hundred twenty nine strains were collected, the predominant species being Escherichia coli (n = 83 [64.3%]). In patients with a ClCr of 30 mL/min, an fT > 50% MIC was reached in more than 90% of the simulations. However, a dose of at least 1 g every 12 h must be administered to reach an fT > 80% MIC. In patients with a ClCr of 30-60 mL/min, the probability of reaching an fT > 50% MIC was higher than 90% with doses of 1 g every 8 h or more, but this value was not reached in > 90% simulations for any of the doses tested in this study. CONCLUSIONS: Standard cefepime dosing can reach an adequate PK/PD index in frail patients. Nevertheless, a high dose or extended infusion is necessary to reach an fT > 80% MIC in patients with a ClCr > 60 mL/min.

Factors associated with short-term mortality after emergency department care of residents living in aged care homes: findings from the multicenter Caregency study. / Factores asociados con mortalidad a corto plazo en personas que viven en residencias atendidas en servicios de urgencias: resultados del estudio multicéntrico Caregency.

OBJECTIVES: To evaluate short-term mortality in people transferred from aged care homes for treatment in a hospital emergency department (ED) and to analyze factors associated with mortality. MATERIAL AND METHODS: Multicenter study of a random sample of retrospective data of patients treated in 5 EDs in Catalonia in 2017. The patients were over the age of 65 years and lived in residential care facilities. In addition to short-term mortality (in the ED or within 30 days of discharge), we analyzed sociodemographic characteristics, prior functional and cognitive status, multimorbidity, triage level on arrival, length of stay in the ED, and hospital admission. Odds ratios (ORs) for factors associated with short-term mortality were calculated by multivariate regression analysis. RESULTS: A total of 2444 ED admissions were analyzed. The patients' mean (SD) age was 85.9 (7.1) years, and 67.7% .were women. Short-term mortality (in 15.5%) was associated with age >90 years (OR, 1.50; 95% CI, 1.5-1.95 years), a Charlson index >2 (OR, 1.47; 95% CI, 1.14-1.90), and dependency assessed as moderate (OR, 1.50; 95% CI, 1.03- 2.20) or severe (OR, 2.56; 95% CI, 1.84-3.55). Other associated factors were a higher level of urgency on triage, duration of ED stay, and hospital admission. CONCLUSION: Aged residents with the characteristics associated with short-term mortality could benefit from interventions for potentially avoiding unnecessary transfers to an ED, and from the implementation of comprehensive geriatric care within the ED. This could be useful to support good quality of care at the end of life.

OBJETIVO: Evaluar la frecuencia y los factores asociados con la mortalidad a corto plazo de personas que viven en residencias tras ingreso en urgencias. METODO: Análisis retrospectivo multicéntrico de una muestra aleatoria de admisiones de personas $ 65 años que viven en residencias en cinco servicios de urgencias de Cataluña, a lo largo de 2017. Se analizaron características sociodemográficas, el estado funcional y cognitivo previo, multimorbilidad, nivel de triaje de las urgencias, duración de la estancia en urgencias, hospitalización y mortalidad a corto plazo (en urgencias o en los 30 días posteriores al alta). Se utilizó un análisis de regresión multivariante para investigar los factores asociados con la mortalidad a corto plazo. RESULTADOS: Se analizaron 2.444 admisiones en urgencias, con una edad media de 85,9 (DE 7,1) años, 67,7% mujeres. La mortalidad a corto plazo (15,5%) se asoció con una edad > 90 años (OR 1,50; IC 95%: 1,5-1,95), un índice de Charlson > 2 (OR 1,47; IC 95%: 1,14-1,90), y un grado de dependencia moderado (OR 1,50; IC 95%: 1,03-2,20) y grave (OR 2,56; IC 95%: 1,84-3,55). También se asoció con un mayor nivel de triaje de la urgencia, duración de la estancia en urgencias e ingreso en planta de hospitalización. CONCLUSIONES: Los ancianos residentes con las características descritas podrían beneficiarse especialmente de intervenciones dirigidas a la prevención de traslados potencialmente innecesarios a urgencias y a la implementación de una atención integral geriátrica dentro de los servicios de urgencias, a fin de garantizar una buena calidad de los cuidados en fases finales de la vida.

Development of an Emergency Revisit Score for Patients With Drug-Related Problems.

Background: Drug-related problems (DRPs) are a frequent reason for emergency departments (EDs) visits. However, data about the risk factors associated with EDs revisits are limited. Objective: To develop and validate a predictive model indicating the risk factors associated with EDs revisit within 30 days of the first visit. Methods: A retrospective cohort study was conducted involving patients who attended an ED for DRPs related to cardiovascular drugs. A 30-day prediction model was created in a derivation cohort by logistic regression. An integer score proportional to the regression coefficient was assigned to the variables with P < .100 in the multivariate analysis. Results: 581 patients (mean age: 80.0 [12.6] years) were included, 133 (22.9%) revisited the ED within 30 days from discharge. Six factors (chronic kidney disease, chronic heart failure, visit to an ED in the preceding 3 months, high anticholinergic burden, DRPs associated with heparin, and safety-related DRPs) were identified as risk factors and combined into a final score, termed the DREAMER score. The model reached an area under the receiver operating curve values of 0.72 (95% confidence interval [CI] = 0.67-0.77) in the referral cohort and 0.71 (95% CI = 0.65-0.74) in the validation cohort (P = .273). Three risk categories were generated, with the following scores and estimated risks: low risk (0-8 points): 11.6%; intermediate risk (9-14 points): 21.3%; and high risk (>14 points): 41.2%. Conclusion and Relevance: The DREAMER score identifies patients at high risk for ED revisit within 30 days from the first visit for a DRPs, being a useful tool to prioritize interventions on discharge.

The usefulness of measuring the anion gap in diagnosing metformin-associated lactic acidosis: a case series.

BACKGROUND: Metformin-associated lactic acidosis (MALA) is a widely documented adverse event of metformin. Despite being considered one of the main causes of metabolic acidosis, the association between an anion gap and MALA diagnosis is still uncertain. CASE PRESENTATION: Cases involving six Caucasian patients with suspected MALA who were admitted to the emergency department were analysed. All these patients presented with pH values < 7.35, lactate levels > 2 mmol/L, and estimated glomerular filtration < 30 mL/min. Metformin plasma concentrations were > 2.5 mg/L in all the patients. The highest metformin concentrations were not found in the patients with the highest lactate levels. The anion gap values ranged from 12.3 to 39.3, with only two patients exhibiting values > 14. CONCLUSIONS: In patients with MALA, there is a significant variability in the anion gap values, which is not related to the level of metformin accumulation, and therefore, it is doubtful whether measuring anion gaps is useful as an approach for MALA diagnosis.

The importance of organizational variables in treatment time for patients with ST-elevation acute myocardial infarction improve delays in STEMI.

BACKGROUND: The time between arrival at the emergency department (ED) and balloon (D2B) in STEMI is one of the best indicators of the quality of care. Our aim is to describe treatment times and evaluate the causes of delay. METHODS: This is an observational retrospective study, including all consecutive STEMI code patients ≥18 years old treated in the ED from 2013 to 2016.All the patients were stratified into two groups: delayed group with D2B>70min and non-delayed ≤70. The primary variable was D2B time. FINDINGS: In total 327 patients were included, stratified according to their D2B as follows: 166 (67·48%) in the delayed group and 80 (32·52%) in the non-delayed group. The delayed group was older (p=0·005), with more females (p=0·060) and more atypical electrocardiogram (ECG) STEMI signs or symptoms (p=0·058) (p=0·087). Predictors of shorter D2B time were: typical STEMI ECG signs and short training sessions for nurses on identifying STEMI patients. INTERPRETATION: There are delays particularly in specific groups with atypical clinical presentations. Short training sessions aimed at emergency nurses correlate with shorter delay. This suggests that continuing training for emergency nurses, along with organizational strategies, can contribute to increasing the quality of care. CLINICAL TRIAL NUMBER: NCT04333381.

Anticholinergic burden in patients treated for constipation in an emergency department. / Carga anticolinérgica en pacientes atendidos por estreñimiento en un servicio de ugencias.

OBJECTIVES: To evaluate the anticholinergic burden on discharge of patients treated for constipation in an emergency department (ED) and to assess the effect on emergency revisiting within 30 days. MATERIAL AND METHODS: Observational retrospective cohort study. We collected cases with a discharge diagnosis of constipation after ED treatment between September 2018 and June 2019 and recorded information on all drugs taken and the anticholinergic burden of treatment. A revisit to the ED within 30 days was the primary outcome. RESULTS: We included 104 patients. A high anticholinergic burden of treatment was identified in 47 (56.6%), an intermediate burden in 30 (36.1%), and a low burden in 6 (7.2%). Twenty-nine (27.9%) patients revisited the ED within 30 days of discharge. An intermediate anticholinergic burden (23 patients [31.1%] vs 4 [13.3%]; P = .061) and high burden (19 [40.4%] vs 8 [14.1%]; P = .002] was associated with revisiting within 30 days in the univariate analysis. On multivariate analysis, a high anticholinergic burden was independently associated with a higher rate of revisiting than a low burden: adjusted odds ratio (aOR), 4.21; 95% CI, 1.07-16.5; P = .039. An intermediate load was not associated with more revisits, however: aOR, 1.27; 95% CI, 0.25-6.41; P = .776. Prescription of long-term treatment with laxatives on discharge did not reduce revisiting withing 30-days in the group with a high anticholinergic load (OR, 0.86; 95% CI, 0.48-3.27; P = .526), but it did have an effect in patients an intermediate burden (OR, 0.13; 95% CI, 0.02-0.99; P = .049). CONCLUSION: The prescription of drugs leading to a high anticholinergic burden was a factor associated with ED revisits within 30 days in patients treated for constipation.

OBJETIVO: Evaluar la frecuencia e impacto de la carga anticolinérgica del tratamiento en la reconsulta a los 30 días en los pacientes atendidos por estreñimiento en un servicio de urgencias (SU). METODO: Estudio observacional de cohortes retrospectivo. Se incluyeron por oportunidad pacientes que fueron dados de alta con diagnóstico de estreñimiento desde un SU entre septiembre 2018 y junio 2019. Se recogieron los fármacos y su carga anticolinérgica. La variable de resultado fue la reconsulta por cualquier causa a los 30 días. RESULTADOS: Se incluyeron 104 pacientes, 47 (56,6%) se clasificaron como tratamiento con alta carga colinérgica, 30 (36,1%) intermedia y 6 (7,2%) baja. Veintinueve (27,9%) pacientes sufrieron una reconsulta a urgencias en los primeros 30 días tras el alta. Los pacientes con fármacos con una carga anticolinérgica alta tuvieron una mayor frecuencia de reconsultas a 30 días [19/47 (40,4%) vs 8/57 (14,1%); p = 0,002]. Tras el análisis multivarible, en comparación con aquellos con tratamiento con baja carga anticolinérgica, el tener una alta carga (ORa = 4,21; IC 95% 1,07-16,5; p = 0,039), pero no intermedia (ORa = 1,27; IC 95% 0,25-6,41; p = 0,776), se asoció de forma independiente con una mayor reconsulta a los 30 días. La prescripción de laxantes crónicos al alta no redujo la reconsulta a 30 días en el grupo con alta carga anticolinérgica (OR = 0,86; IC 95% 0,48-3,27; p = 0,526), pero sí en aquellos con carga intermedia (OR = 0,13; IC 95% 0,02-0,99; p = 0,049). CONCLUSIONES: La prescripción de fármacos con alta carga anticolinérgica fue un factor asociado con reconsulta a los 30 días en los pacientes atendidos por estreñimiento en urgencias.

Learn, unlearn, and learn again: the secret to changing how elderly patients are attended in the emergency department. / Aprender, desaprender y reaprender para asistir ancianos en urgencias: el secreto del cambio.

The demographic shift toward ever greater numbers of older patients with multiple conditions and functional dependency has increased pressure on emergency departments (EDs). The traditional approach to emergency treatment does not resolve problems in this population, creates risk, leads to high admission rates, and collapses the ED itself. Medical associations recommend that multidisciplinary teams incorporate geriatric assessment strategies and procure safe care enviroments. Implementing such recommendations will require profound changes in ED processes and staff and in connections between the ED and the community the patient is discharged to. This paper describes the processes we used in our tertiary-care hospital to achieve the necessary level of change. Our aims were to ensure that the ED staff provides correct diagnoses and treatments for elderly patients; bases decisions on the patients' clinical, social and functional needs and the preferences of both patient and family; and arranges for the most appropriate treatment environment in each case. All these changes were essential for properly addressing new care demands while achieving optimal patient outcomes and contributing to better ED and hospital performance.

El importante cambio demográfico, con el incremento de personas ancianas con multimorbilidad y dependencia funcional, conlleva un aumento de presión sobre los servicios de urgencias (SUH). En esta población, la atención clásica desarrollada en los SUH no es resolutiva, comporta riesgos para las personas, implica tasas altas de ingreso y contribuye a aumentar la saturación del propio SUH. Las sociedades científicas recomiendan incorporar estrategias de valoración geriátrica en el SUH a cargo de equipos multidisciplinares, y procurar entornos seguros. Una organización de este estilo requiere de un profundo cambio del propio servicio, de sus profesionales y de las conexiones con el entorno post-hospitalario. Exponemos la experiencia del SUH de un hospital terciario y los mecanismos utilizados para conseguir ese cambio. El objetivo es garantizar que el equipo del SUH lleve a cabo unos cuidados y un diagnóstico y tratamiento correctos de los procesos urgentes en la población anciana, tome decisiones ajustadas a las necesidades clínicas, sociales, funcionales, a los deseos del paciente y su familia, y elija el entorno de tratamiento mejor en cada caso. Todo ello son cambios imprescindibles para atender adecuadamente una nueva demanda, conseguir resultados óptimos para los pacientes y para el funcionamiento del SUH y del hospital.
