Objective: This study aimed to examine the relationship between systemic inflammation and changes in activities of daily living (ADLs) in elderly patients with heart failure (HF) during their admission to convalescent rehabilitation wards.

Method: This study included 90 elderly patients with HF admitted to the convalescent rehabilitation wards. Data were collected on basic attributes, medical attributes, and functional independence measured using the functional independence measure (FIM) at both admission and discharge. Systemic inflammation was assessed using the modified Glasgow Prognostic Score (mGPS). Patients were classified into two groups based on their mGPS scores: low inflammation and high inflammation. Furthermore, these groups were compared according to the mGPS.

Result: The high inflammation group showed significantly lower motor FIM scores at admission as well as lower motor and cognitive FIM scores at discharge. Additionally, the high inflammation group showed lower motor FIM gain, motor FIM efficiency, and performance index compared to the low inflammation group.

Conclusion: Systemic inflammation in elderly patients with HF in convalescent rehabilitation wards may associated with changes in ADLs during hospitalization.
