The impact of mobilization training time during the first postoperative week on the length of hospital stay in postoperative patients admitted to an intensive care unit.

Abstract

To determine the impact of mobilization training time during the first postoperative week on the length of hospital stay for postoperative patients admitted to an intensive care unit. A retrospective cohort study. Consecutive patients who underwent elective surgery and stayed in the intensive care unit of a university hospital for more than 48 h between July 2017 and August 2020 were enrolled. The total duration of mobilization training during the first postoperative week and clinical variables, including demographic information, were collected from medical records. Multivariable regression analysis was used to investigate the impact of mobilization training time on the length of hospital stay, adjusting for potentially confounding variables. In total, 773 patients (504 males; median age, 70 years) were enrolled. Multivariable regression analysis showed that an increase in mobilization training time during the first postoperative week was associated with a shorter length of hospital stay (β = -0.067, 95% confidence interval: -0.120, -0.017, p = 0.010), with each 1-h increase in training time associated with a 4.02-day reduction in the length of hospital stay. Increased mobilization training during the first postoperative week significantly reduced the length of hospital stay in postoperative patients.
