Influence of process-focused patient care on clinical outcomes among hospitalized heart failure patients in the cardiology ward

Abstract Background The implementation of a process-oriented organizational structure in patient care allows for a comprehensive and optimized approach. In the context of heart failure (HF), it remains uncertain whether the establishment of a specialized hospitalisation team can contribute to improved major clinical outcomes. Purpose To analyse the rates of all-cause hospitalisation, cardiovascular hospitalization, HF hospitalization and overall mortality at 180 days among patients admitted to the Cardiology ward for HF, both prior to and after the implementation of a specialized HF hospitalisation team. Methods The study included all patients discharged from the Cardiology department with HF as the primary diagnosis and subsequent outpatient follow-up by the Community HF Unit in both 2019 and 2022. Clinical outcomes were compared between two distinct periods: the pre-implementation year of 2019 and the subsequent year of 2022, characterized by process-oriented HF care. Statistical analyses were performed using Kaplan-Meier and adjusted Cox proportional-hazards models. Results A total of 140 patients were enrolled in the study, comprising 55 individuals receiving care from a conventional ward team in 2019 and 85 under the specialized HF team in 2022. The mean age of the cohort was 69.4 years (+/-11.8), with a mean LVEF of 40.6%. The pre-implementation group showed a higher percentage of male patients (73% vs. 47%; p=0.003) and LVEF was lower in the HF team period (38.9% vs. 43.4%; p=0.045), with no statistically significant differences in other baseline variables. As shown in figure 1, over 180 days of follow-up, 15 patients (27.6%) were admitted to hospital in the conventional ward team period and 13 (15.3%) in the HF team period (hazard ratio [HR] 0.44; 95% confidence interval [CI] 0.19 to 0.99; P=0.047). Of these hospitalisations, 13 patients (23.6%) in pre-implementation period and 10 (11.8%) in post-implementation period were attributed to cardiovascular events (HR 0.40; 95% CI 0.16 to 0.99; P=0.049). Additionally, there was a reduction in the rate of heart failure admissions in the post-implementation period compared to the pre-implementation time (HR 0.30; 95% CI 0.09 to 0.94; P=0.039). Furthermore, a significant decline in all-cause of death was observed in patients treated by HF-team in 2022 compared to patients receiving care from the conventional ward team (log-rank test, p=0.015). Conclusions The implementation of a process-oriented organizational model within the Cardiology unit consisting in the provision of patient care by a team specialized in HF management, is associated with a statistically significant reduction in major clinical outcomes such as all-cause hospitalization, cardiovascular hospitalization and HF readmission, alongside a reduction in overall mortality rates at 180 days.
