Early mobilization practices of mechanically ventilated patients: a 1-day point-prevalence study in southern Brazil

Abstract

OBJECTIVES: To assess early mobilization practices of mechanically ventilated patients in southern Brazilian intensive care units (ICUs) and to identify barriers associated with early mobilization and possible complications.

METHODS: A prospective, observational, multicenter, 1-day point-prevalence study was conducted across 11 ICUs and included all mechanically ventilated adult patients. Hospital and ICU characteristics and patients’ demographic data, the highest level of mobilization achieved in the 24 hours prior to the survey and related barriers, and complications that occurred during mobilization were collected in the hospital and the ICU.

RESULTS: A total of 140 patients were included with a mean age of 57±17 years. The median and interquartile range was 7 (3-17) days for the length of ICU stay to the day of the survey and 7 (3-16) days for the duration of mechanical ventilation (MV). The 8-level mobilization scale was classified into two categories: 126 patients (90%) remained in bed (level 1-3) and 14 (10%) were mobilized out of bed (level 4-8). Among patients with an endotracheal tube, tracheostomy, and noninvasive ventilation, 2%, 23%, and 50% were mobilized out of bed, respectively (p<0.001 for differences among the three groups). Weakness (20%), cardiovascular instability (19%), and sedation (18%) were the most commonly observed barriers to achieving a higher level of mobilization. No complications were reported.

CONCLUSIONS: In southern Brazilian ICUs, the prevalence of patient mobilization was low, with only 10% of all mechanically ventilated patients and only 2% of patients with an endotracheal tube mobilized out of bed as part of routine care.
