Abstract
BACKGROUND: The promotion of early mobilization following critical illness is tempered by national reports of patient and institutional barriers to this approach. We carried out a survey to assess current knowledge, perceptions and practices of Canadian physicians and physiotherapists with respect to acquired weakness and early mobilization in adults in the intensive care unit (ICU). METHODS: We conducted a cross-sectional, self-administered postal survey among critical care physicians and physiotherapists in all 46 academic ICUs in Canada in 2011-2012. To identify all physicians and physiotherapists working in the ICUs, we contacted division heads and senior physiotherapists by telephone or email. We designed, tested and administered a questionnaire with the following domains: knowledge of ICU-acquired weakness and early mobilization; personal views of, perceived barriers to and adequacy of technical skills for early mobilization; assessments for initiation of early mobilization and permissible activity levels by patient physiologic characteristics, diagnoses and therapies; staffing issues; and sedation practices. RESULTS: The overall response rate was 71.3% (311/436); it was 64.2% (194/302) among physicians and 87.3% (117/134) among physiotherapists. A total of 214 respondents (68.8%) underestimated the incidence of ICU-acquired weakness in the general medical-surgical ICU population, and 186 (59.8%) stated they had insufficient knowledge or skills to mobilize patients receiving mechanical ventilation. Excessive sedation, medical instability, limited staffing, safety concerns, insufficient guidelines and insufficient equipment were common perceived barriers to early mobilization. INTERPRETATION: Physicians and physiotherapists in the ICU underestimated the incidence of ICU-acquired weakness and felt inadequately trained to mobilize patients receiving mechanical ventilation. We identified multiple modifiable barriers to early mobilization at the institutional, health care provider and patient levels that need to be addressed when designing mobilization programs for critically ill adults.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
