Basic characteristics of the study participants.

It is important to establish the relationship between appropriate nutritional intake and improvements in activities of daily living (ADLs) in elderly hospitalized patients. This prospective observational study aimed to investigate diet order compliance (DOC) during 8 weeks of hospitalization and calculate the odds of improved functional independence measure (FIM) scores for high- and low-DOC groups using covariate-adjusted models in geriatric convalescent hospitals. The study subjects were elderly inpatients (>65 years old) with degenerative disease who consumed prescribed oral meals (Functional Oral Intake Scale (FOIS) = 6/7) and who did not receive physical/occupational therapy. The personalized diet order was prescript, and the DOC was calculated using dietitian-monitored daily intake data. The 73 patients were divided into a low-DOC group (
