Hospital Readmissions of Patients with Heart Failure: The Impact of Hospital and Primary Care Organizational Factors in Northern Italy

Abstract

BackgroundPrimary health care is essential for an appropriate management of heart failure (HF), a disease which is a major clinical and public health issue and a leading cause of hospitalization. The aim of this study was to evaluate the impact of different organizational factors on readmissions of patients with HF.MethodsThe study population included elderly resident in the Local Health Authority of Bologna (Northern Italy) and discharged with a diagnosis of HF from January to December 2010. Unplanned hospital readmissions were measured in four timeframes: 30 (short-term), 90 (medium-term), 180 (mid-long-term), and 365 days (long-term). Using multivariable multilevel Poisson regression analyses, we investigated the association between readmissions and organizational factors (discharge from a cardiology department, general practitioners’ monodisciplinary organizational arrangement, and implementation of a specific HF care pathway).ResultsThe 1873 study patients had a median age of 83 years (interquartile range 77–87) and 55.5% were females; 52.0% were readmitted to the hospital for any reason after a year, while 20.1% were readmitted for HF. The presence of a HF care pathway was the only factor significantly associated with a lower risk of readmission for HF in the short-, medium-, mid-long- and long-term period (short-term: IRR [incidence rate ratio]=0.57, 95%CI [confidence interval]=0.35–0.92; medium-term: IRR=0.70, 95%CI=0.51–0.96; mid-long-term: IRR=0.79, 95%CI=0.64–0.98; long-term: IRR=0.82, 95%CI=0.67–0.99), and with a lower risk of all-cause readmission in the short-term period (IRR=0.73, 95%CI=0.57–0.94).ConclusionOur study shows that the HF care specific pathway implemented at the primary care level was associated with lower readmission rate for HF in each timeframe, and also with lower readmission rate for all causes in the short-term period. Our results suggest that the engagement of primary care professionals starting from the early post-discharge period may be relevant in the management of patients with HF.

Development of a prediction model for 30-day acute readmissions among older medical patients: the influence of social factors along with other patient-specific and organisational factors

“…Studies have highlighted that readmission risk is influenced by both comorbidities treated outside hospital in the primary healthcare sector and organisational factors 8 42 43. To our knowledge, prediction studies have not previously included chronic condition information from non-hospital data sources.…”

Effectiveness of Mobile Phone-Based Interventions for Improving Health Outcomes in Patients with Chronic Heart Failure: A Systematic Review and Meta-Analysis

“…Despite advances in HF treatment, primary health outcomes, such as hospitalization rates and health-related quality of life (QoL), have not improved significantly [3,4]. According to recent studies, approximately 23%-58% of chronic HF patients at follow-up one year later were re-admitted to hospitals [5,6]. Chronic HF affects the elderly in particular, with 80% of HF-related hospitalizations and 90% of HF-related deaths occurring among patients aged 65 years or older [7].…”

The effect of primary care on potentially avoidable hospitalizations in France: a cross-sectional study

“…Inside the health system sector, the factors mostly pertain to the primary care sector. They include prevention, transitional care, patients' involvement, continuity of care, and access to and utilization of primary care [10][11][12][13][14]. Published evidence suggests a protective role of General Practitioners' (GP) density and of utilization of GP services [15].…”
