Policies were analyzed using content analysis to systematically identify common practices and differences across key areas, including risk identification, clinical criteria, leadership roles, early discharge planning, and patient engagement. A coding framework was developed based on Ontario Health guidelines and used as a comprehensive guiding document for comparison.
