Abstract

This study investigated the relationship between the activities of daily living and the length of hospitalization to determine the optimal length of hospitalization for patients with schizophrenia. We collected information from all schizophrenia patients discharged in Peking University Huilongguan Clinical Medical School from January 1, 2015 to December 31, 2015. A total of 1967 patients were enrolled in this study. The Chinese version of the modified Barthel index (MBI-C) was used to assess patients’ actual performance on activities of daily living. We used the paired samples t-test to compare MBI-C scores at admission and discharge and performed correlation analysis to find the trend of MBI-C change with length of hospitalization. The average length of hospitalization was 73.3 ± 42.2 days. There were significant differences between the MBI-C scores at the time of discharge from hospital compared with those at the time of admission to the hospital (93.4 ± 11.2 vs. 88.7 ± 11.8; P < 0.001). Taking the length of hospitalization as the grouping boundary value, the correlation analysis of the subgroup found that below a minimum of 20 days, the improvement in the MBI-C scores increased with the increase of length of hospitalization, and above a maximum of 50 days, the improvement in the MBI-C scores decreased with the increase of length of hospitalization. The optimal length of hospitalization for patients with schizophrenia may lie between 20 and 50 days, with regard to the recovery of daily living function.
