Safety of Patient Mobilization and Rehabilitation in the Intensive Care Unit. Systematic Review with Meta-Analysis
Bibliographic record
Abstract
BACKGROUND: Early mobilization and rehabilitation of patients in intensive care units (ICUs) may improve physical function, and reduce the duration of delirium, mechanical ventilation, and ICU length of stay. However, safety concerns are an important barrier to widespread implementation. OBJECTIVES: To synthesize safety data regarding patient mobilization and rehabilitation in the ICU, including falls, removal of endotracheal tubes, removal or dysfunction of intravascular catheters, removal of other catheters/tubes, cardiac arrest, hemodynamic changes, and desaturation. DATA SOURCES: Systematic literature review, including searches of five databases. Eligible studies evaluated patients who received mobilization-related interventions in the ICU. Exclusion criteria included: (1) case series with fewer than 10 patients; (2) majority of patients under 18 years of age; and (3) data not reported to permit calculation of incidence of safety events. DATA EXTRACTION: Number of patients, mobilization/rehabilitation sessions, potential safety events, and events with negative consequences (e.g., requiring intervention or additional therapy). SYNTHESIS: statistics, and bias assessed by the Newcastle-Ottawa Scale and Cochrane risk of bias assessment. The literature search identified 20,660 titles. There were 48 eligible publications evaluating 7,546 patients, with 583 potential safety events occurring in 22,351 mobilization/rehabilitation sessions. There was a total of 583 (2.6%) potential safety events with heterogeneity in the definitions for these events. For the safety event types that could be meta-analyzed, pooled incidences per 1,000 mobilization/rehabilitation sessions (95% confidence interval), were: hemodynamic changes, 3.8 (1.3-11.4), and desaturation, 1.9 (0.9-4.3). A total of 24 studies of 3,404 patients reported on any consequences of potential safety events (e.g., needing to increase dose of vasopressor due to mobility-related hypotension), with a frequency of 0.6% in 14,398 mobilization/rehabilitation sessions. CONCLUSIONS: Patient mobilization and physical rehabilitation in the ICU appears safe, with a low incidence of potential safety events, and only rare events having any consequences for patient management. Heterogeneity in the definition of safety events across studies emphasizes the importance of implementing existing consensus-based definitions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
