Elderly People With Drug-Related Problems Identified in the Emergency Department : Impact of Therapeutic Complexity on Consultations to the Health System

Different scales have been validated to assess the medication regimen complexity. However, the effect of this complexity on the risk of health care center consultations in patients with drug-related problems is unknown. This study's objective is to evaluate the association between the Medication Regimen Complexity Index (MCRI) and the number of drugs prescribed and new consultations to the health care system in patients who visit an emergency service due to drug-related problems. This is a retrospective observational study. We included patients >65 years who attended in an emergency service for drug-related problems. To identify variables associated with health care center reconsultation, a multivariate analysis was performed, including demographic and comorbidity variables, number of drugs prescribed, and MCRI value. Two hundred and one patients were included. A significant association was found between the prescription of more than five drugs (odds ratio [OR] = 2.50, 95% confidence interval [CI] = [1.08, 5.79]), an MCRI > 20 (2.98 [1.46-6.09]), and an increase in the number of drugs prescribed (2.87 [1.57-5.21]) and its MCRI (2.06 [1.13-3.77]) at discharge and a new visit to the emergency department. An association was found between the prescription of more than five drugs, an MCRI > 20, an increase in the number of drugs, and in MCRI value at discharge and a new visit to any other health care center. The number of prescribed drugs and the medication complexity of patients who visit the emergency department for drug-related problems was associated with an increase in the number of revisits to the emergency department and to other health care centers

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 > 70 min 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: NCT0433338

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.MethodsRetrospective 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.Results851.649 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%.ConclusionThe 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. Risk scores are often used to predict the clinical outcomes of patients in many healthcare settings.To the date, no prediction model of emergency department (ED) visits based on patients' pharmacotherapy, income level, and comorbidities have been developed.We have designed an ED risk score combined four risk factors (sex, age, comorbidity score and income level) and 30 drug categories to identify those patients at high risk of health-care visit

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

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). Our observational, single-center, prospective study consecutively included patients over 65-years-old admitted between March 1, 2021, and April 30, 2021. 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. 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

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 2 mmol/L, and estimated glomerular filtration 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

Cefepime Dosing Requirements in Elderly Patients Attended in the Emergency Rooms

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. 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. 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. 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

Emergency department admissions and economic costs burden related to ambulatory care sensitive conditions in older adults living in care homes

Este trabajo se llevó a cabo dentro del programa de doctorado en Metodología de Investigación Biomédica y Salud Pública de la Universitat Autònoma de Barcelona.Objectives: To assess the frequency of emergency department admissions (EDAs) for ambulatory care sensitive conditions (ACSC) and non-ACSC among older adults living in care homes (CH), to describe and compare their demographic and clinical characteristics, the outcomes of the hospitalization process and the associated costs. Method: This multicenter, retrospective and observational study evaluated 2444 EDAs of older adults ≥65 years old living in care homes in five emergency departments in Catalonia (Spain) by ACSC and non-ACSC, in 2017. Sociodemographic variables, prior functional and cognitive status, and information on diagnosis and hospitalization were collected. Additionally, the costs related with the EDAs were calculated, as well as a sensitivity analysis using different assumptions of decreased admissions due to ACSC. Results: A total of 2444 ED admissions were analyzed. The patients' mean (SD) age was 85.9 (7.2) years. The frequency of ACSC-EDA and non-ACSC-EDA was 56.6% and 43.4%, respectively. Severe dependency and cognitive impairment were present in 56.6% and 78%, respectively, with no differences between the two groups. The three most frequent ACSC were falls/trauma (13.8%), chronic obstructive pulmonary disease/asthma (11.4%) and urinary tract infection (7.4%). The average cost per ACSC-EDA was €1408.24. Assuming a 60% reduction of ACSC-EDA, the estimated cost savings would be €1.2 million. Conclusions: Emergency admissions for ACSC from care homes have a significant impact on both frequency and costs. Reducing these conditions through targeted interventions could redirect the avoided costs toward improving care support in residential settings
