ABSTRACT

ABSTRACT
<b>Background: </b>The current study aimed to investigate factors associated with the prognosis of activities of daily living (ADL) in elderly patients with pneumonia who had undergone rehabilitation during their hospitalization.<br><b>Methods: </b>The study included patients of age ≥65 years who were hospitalized due to pneumonia and had undergone rehabilitation for disuse syndrome at Tsukuba Memorial Hospital. The main outcome was measured using the functional independence measure (FIM) scores to assess ADL. The participants were divided into a high-recovery group (≥80%) and a low-recovery group (<80%) based on the FIM recovery rate score. Further, factors associated with the prognosis of ADL were evaluated using multivariate logistic regression analysis. Basic characteristics, consciousness, usual mode of transportation, FIM score, grip strength, range of motion, orthostatic hypotension, exercise tolerance (6-minutes walking distance), respiratory disorder (Hugh–Jones classification), constipation, malnutrition (mini-nutritional assessment), cognitive (mini-mental state examination), depression (geriatric depression scale), balance (functional balance scale), urinary incontinence, and pressure ulcers were included as the evaluation items.<br><b>Results: </b>Among the 51 elderly patients with pneumonia (average age ± SD; 82.0 ± 11.3), 34 patients were classified in the high-recovery group and 17 in the low-recovery group. In multivariate logistic regression analysis, it was revealed that the number of days from the onset until the initiation of rehabilitation (days of inactivity) and nutritional status were factors associated with a high-recovery FIM score.<br><b>Conclusions: </b>The study results suggest that days of inactivity and early management of nutritional status after hospitalization are important for elderly patients with pneumonia to return to their ADL.
