Treatment Fidelity in 94 Randomized Controlled Trials of… : Critical Care Medicine
with outcomes, we must first understand the extent of treatment fidelity reporting in ICU-based physical rehabilitation randomized controlled trials (RCTs). DATA SOURCES: Six electronic databases from inception to December 2022. STUDY SELECTION: We included RCTs enrolling adults or children admitted to the ICU, if greater than or equal to 50% were invasively mechanically ventilated greater than 24 hours, and underwent an ICU-based physical rehabilitation intervention, with no limitation to comparators or outcomes. DATA EXTRACTION: We screened and extracted data independently and in duplicate, with a third reviewer as needed. Extracted data included study characteristics, treatment descriptions, and the presence of National Institutes of Health Behaviour Change Consortium (NIH-BCC) treatment fidelity tool components. Treatment fidelity scores were calculated as the proportion of reported (numerator) out of total NIH-BCC components (denominator). We calculated scores across studies and b
