Abstract
To provide effective, comprehensive care to increasingly complex patients in Canadian communities, healthcare providers are shifting from solo providers of primary care to interprofessional, team-based primary healthcare services. Team-based care is considered one of the most effective means of caring for complex patients, including frail elders and individuals with chronic illness, mental health issues and addictions. Team-based care relies on effective team processes, the social or relational processes that enhance team collaboration and decision making. This realist review will highlight the team processes associated with high-performing teams and provide team development and sustainment strategies for providers and healthcare decision makers.
