Definition of abbreviations: EM = early mobilization; NS = not significant; PT = physical therapist or physiotherapist.

Factors associated with EM practice and EM protocol in multivariate analyses are listed. Analyses also included the following variables not found to be significantly associated with EM practice or EM protocol: academic affiliation, hospital size, intensive care unit type, a high-intensity staffing model for physicians, a written protocol for sedation administration, and a written protocol for mechanical ventilation weaning.

Data are presented as odds ratio (95% confidence interval), P value.
