REGRESSION
A total of 757 patients were admitted to the department of Pulmonology or Internal Medicine and were screened for eligibility, resulting in 289 eligible patients. Among them, 78 patients were included in this study, with 39 patients randomly allocated to the intervention group and 39 to the control group (Participants had a median (IQR) age of 63 (56–68) years and 44 (56%) of them were male. Characteristics of the study participants are presented in Of the included patients, two (3%) dropped out due to a decline in health. Data of 76 (97%) patients were used in the analysis, of which 38 patients (50%) were in the intervention group and 38 (50%) were in the control group (PA data were collected for a median (IQR) of 4 (2–6) valid measurement days. On day two, PA data were available for 76 patients (100%). On day three, eight patients were discharged, and PA data were available for 68 patients (90%), with 33 in the control group and 35 in the intervention group. During the following days, more patients were discharged and the available PA data per day continued to decrease until day seven (The results of the univariate linear regression analyses showed that time spent walking ranged between 32.5 and 40.6 min in the control group and between 35.9 and 45.5 min in the intervention group. Time spent upright ranged between 58.4 and 69.9 min in the control group and between 64.8 and 77.4 min in the intervention group. Hospital Fit use did not result in a significant increase in time spent walking per day, time spent standing per day, time spent upright per day, or the number of postural transitions from a sedentary to an active position from day two to seven (Next, multiple linear regression analyses were conducted to correct for the potential influence of functional independence (independence on dichotomized mILAS) on the association between Hospital Fit use and PA behavior. The results of the multiple linear regression analyses of the association between Hospital Fit and time spent walking per day are shown in The multiple linear regression analyses of the association between Hospital Fit use and time spent upright per day also showed an increase in time spent upright per day with Hospital Fit use (The sensitivity analysis demonstrated comparable findings between the imputed and the original non-imputed datasets, leading us to conclude that imputation did not lead to large differences.
