Evaluación poblacional del impacto del nivel socioeconómico en los resultados clínicos en pacientes con insuficiencia cardiaca en entornos de atención integrada / Population-based evaluation of the impact of socioeconomic status on clinical outcomes in patients with heart failure in integrated care settings

Introduction and objectives: Low socioeconomic status (SES) is associated with poor outcomes in patients with heart failure (HF). We aimed to examine the influence of SES on health outcomes after a quality of care improvement intervention for the management of HF integrating hospital and primary care resources in a health care area of 209 255 inhabitants.MethodsWe conducted a population-based pragmatic evaluation of the implementation of an integrated HF program by conducting a natural experiment using health care data. We included all individuals consecutively admitted to hospital with at least one ICD-9-CM code for HF as the primary diagnosis and discharged alive in Catalonia between January 1, 2015 and December 31, 2019. We compared outcomes between patients exposed to the new HF program and those in the remaining health care areas, globally and stratified by SES.ResultsA total of 77 554 patients were included in the study. Death occurred in 37 469 (48.3%), clinically-related hospitalization in 41 709 (53.8%) and HF readmission in 29 755 (38.4%). On multivariate analysis, low or very low SES was associated with an increased risk of all-cause death and clinically-related hospitalization (all Ps <.05). The multivariate models showed a significant reduction in the risk of all-cause death (HR, 0.812; 95%CI, 0.723-0.912), clinically-related hospitalization (HR, 0.886; 95%CI, 0.805-0.976) and HF hospitalization (HR, 0.838; 95%CI, 0.745-0.944) in patients exposed to the new HF program compared with patients exposed to the remaining health care areas and this effect was independent of SES.ConclusionsAn intensive transitional HF management program improved clinical outcomes, both overall and across SES strata.

Introducción y objetivos: El nivel socioeconómico (NSE) bajo se asocia con malos resultados en pacientes con insuficiencia cardiaca (IC). Nuestro objetivo es examinar la influencia del NSE en los resultados de salud tras una intervención de mejora de la calidad en el abordaje de la IC en un área de salud integrada de 209.255 habitantes.MétodosSe efectuó una evaluación pragmática poblacional utilizando bases de datos administrativas y sanitarias. Se incluyó a todas las personas consecutivas hospitalizadas con un código CIE-9-CM de IC como diagnóstico principal y dadas de alta vivas en Cataluña entre el 1 de enero de 2015 y el 31 de diciembre de 2019. Se compararon los resultados entre los pacientes expuestos al nuevo programa de IC y los de las demás áreas asistenciales, en general y según su NSE.ResultadosSe incluyó a 77.554 pacientes. Los eventos adversos fueron: muerte en 37.469 (48,3%), hospitalización clínicamente relacionada en 41.709 (53,8%) y reingreso por IC en 29.755 (38,4%). El NSE bajo o muy bajo se asoció con un mayor riesgo de eventos clínicos adversos (p <0,05). Se observó una reducción significativa del riesgo de muerte (HR=0,812; IC95%, 0,723-0,912), hospitalización relacionada con la clínica (HR=0,886; IC95%, 0,805-0,976) y por IC (HR=0,838; IC95%, 0,745-0,944) en los pacientes expuestos al nuevo programa frente a los de las demás áreas sanitarias y este efecto fue independiente del NSE.ConclusionesUn programa de atención transicional para la IC mejoró los resultados clínicos, tanto en general como en todos los estratos de NSE.

Heart failure admission across glomerular filtration rate categories in a community cohort of 125,053 individuals over 60 years of age.

A reduced estimated glomerular filtration rate (eGFR) has been described as a predictor of heart failure (HF). However, the increased risk across eGFR categories has not been fully evaluated, which is especially relevant in older individuals in whom both the prevalence of HF and decreased eGFR are higher. Furthermore, this association has not been studied in Mediterranean populations, where coronary heart disease (CHD), a frequent cause of HF, has a low prevalence. We performed a retrospective cohort study using the electronic medical records from primary and hospital settings in northeastern Spain. We included 125,053 individuals ≥60 years old with the determination of creatinine and without diagnosis or previous admission due to HF. The eGFR was calculated according to the CKD-EPI formula and classified by clinical categories. The association between eGFR, as a continuous and categorical variable, and the risk of admission due to HF was assessed by Cox proportional risk analysis, considering death as a competitive risk. During a median follow-up of 38.8 months, 2,176 individuals (1.74%) were hospitalized due to HF. The unadjusted admission rates were 4.02, 13.0, 26.0, and 48.6 per 1000 person-years for eGFR > 60, 45-59, 30-44, and 15-29 ml/min/1.73 m2, respectively. The corresponding hazard ratios (95% confidence interval; reference eGFR 60-89) were 1.38 (95% CI 1.23-1.55), 2.02 (95% CI 1.76-2.32) and 3.46 (95% CI 2.78-4.31). In this Mediterranean community-based cohort of individuals ≥60 years old without previous HF, the risk of admission due to HF gradually increased with decreasing eGFR.
