Key result
90-day HF readmission is linked to higher 90-day mortality in super-aged patients.
Why the study?
The increasing prevalence of HF in aging populations challenges healthcare systems, prompting examination of hospitalization incidence and the impact of physician experience on prognosis in an insular super-aged cohort.
Is physician experience or 90-day readmission associated with all-cause mortality in a super-aged heart failure cohort?
Observational (n=218)
Is physician experience or 90-day readmission associated with all-cause mortality in a super-aged heart failure cohort?
p-value: p=0.02
In a super-aged heart failure cohort, 90-day readmission, but not physician experience, was significantly associated with increased all-cause mortality.
90-day HF readmission marks higher short-term mortality in super-aged patients; leaves open whether prevention strategies improve outcomes.
Background: The increasing prevalence of heart failure (HF) in aging populations challenges healthcare systems, especially in rural and insular regions of super-aged societies. This study examines hospitalization incidence rates (IRs) and the association between physician experience and HF prognosis in an insular super-aged cohort. Methods and Results: We conducted a retrospective population-based observational study including patients first hospitalized for HF between 2015 and 2019. Among 218 patients, 30 in-hospital deaths were excluded and 188 patients were followed up. We estimated hospitalization and readmission IRs and analyzed the association between physician experience and HF prognosis. Additionally, we conducted a landmark analysis 90 days post-discharge for readmissions. The first hospitalization IR for HF was 135/100,000 person-years (112 men, 157 women), and both rates increased with age. The median age was 86 years; 33% were ≥90 years, and 58% were female. Landmark analysis showed that 90-day all-cause mortality was significantly higher in patients with readmission than in those without (P=0.02). The multivariate Cox model confirmed a significant association between 90-day readmissions and all-cause mortality. The physician experience was not significantly associated with HF prognosis. Conclusions: This study highlighted the hospitalization IR for HF in a super-aged society and the high risk of all-cause mortality associated with 90-day readmissions. No significant association was identified between physician experience and HF prognosis.

Mizuta et al. (2025) conducted an observational in Heart failure (n=218). Physician experience and 90-day readmission vs. No readmission was evaluated on 90-day all-cause mortality (p=0.02). In a super-aged cohort, 90-day readmission for heart failure was significantly associated with higher 90-day all-cause mortality (P=0.02), while physician experience was not associated with prognosis.
