Optimal timing for early mobilization initiatives in intensive care unit patients: A systematic review and network meta-analysis.

Objectives: Analyse the effect of varying start times for early exercise interventions on the prevention of intensive care unit-acquired weakness.
Research Methodology: We conducted a comprehensive search on PubMed, Cochrane Library, Web of Science, Embase, China Biology Medicine Disc, China National Knowledge Infrastructure, Wan Fang Database, and reference lists up to May 2023.
Setting: We systematically searched the literature for all randomized controlled trials on the effect of early mobilization in patients with critical illness.
Main Outcome Measures: The primary outcome assessed was the incidence of intensive care unit-acquired weakness. The secondary outcomes included: the Medical Research Council Score, the Barthel Index, duration of mechanical ventilation, length of intensive care unit stay, total length of hospital stay, mortality and incidence of intensive care unit-related complications.
Results: The results of meta-analysis showed that compared with routine care, less than 24 hours after admission (RR = 0.44, 95 %CI: 0.28-0.68), more than 24 hours (RR = 0.33, 95 %CI: 0.16-0.67), less than 72 hours after admission (RR = 0.33, 95 %CI: 0.20-0.52) may lead to a lower incidence of intensive care unit-acquired weakness. The results of under surface cumulative ranking showed that early mobilization within 72 hours may have the lowest incidence of intensive care unit-acquired weakness (SUCRA = 81.9 %).
Conclusions: The current empirical evidence from intensive care unit patients suggests that initiating mobilization protocols within 24-72 hours timeframe following admission to the intensive care unit could potentially be the most beneficial strategy to reduce the incidence of intensive care unit-acquired weakness and the related medical complications. Moreover, this strategy seems to significantly improve rehabilitation and treatment outcomes for these patients.
Implications for Clinical Practice: According to this study, medical and nursing staff in the intensive care unit have the chance to identify the most suitable timing for the implementation of early rehabilitative measures for patients. This can potentially prevent intensive care unit-acquired weakness and enhance various clinical outcomes for patients.
