Examination of factors related to the performance index of patients with cardiovascular disease in a convalescent rehabilitation hospital. Jpn J Compr Rehabil Sci 2024; 15: 63-70.Objective: The purpose of this study was to identify the characteristics of patients with cardiovascular disease who received cardiac rehabilitation (CR) at a convalescent rehabilitation hospital (rehabilitation hospital) after treatment at an acute-care hospital and whose performance index was 40 or higher.Methods: A total of 43 patients with cardiovascular disease were admitted to two rehabilitation hospitals. Based on the performance index, which is an indicator of the effectiveness of rehabilitation in rehabilitation hospitals, patients were classified into two groups: a “high-performance index group” (performance index of 40 or higher) and a “low-performance index group” (performance index of less than 40). We then compared the patient characteristics of the two groups.Results: The high-performance group accounted for 62.8% of the total. Compared to patients in the low-performance group, high-performers were significantly younger at the time of admission to the rehabilitation hospital and had significantly higher physical function and exercise tolerance. The results of the effect size measurement showed that the effect size was 0.98 and 0.93 on the Short Physical Performance Battery (SPPB) at admission to the rehabilitation hospital and on the pre-illness Kihon checklist, respectively, which were related to the achievement of the performance index.Conclusions: This study suggests that the SPPB at admission to a rehabilitation hospital and the pre-illness Kihon checklist are associated with obtaining a performance index of 40 or higher in patients with cardiovascular disease.
