Implementation of interprofessional team-based care: A cross-case analysis

Two out of five Canadians have at least one chronic disease and four out of five are at risk of developing a chronic disease. Successful disease management relies on interprofessional team-based approaches, yet lack of purposeful cultivation and patient engagement has led to systematic inefficiencies. Two primary care teams in Southwestern Ontario implementing interprofessional chronic care programs for patients with chronic obstructive pulmonary disease were compared. A mixed-methods cross-case analysis was conducted including interviews, focus groups, observations and document analysis. Cases (n = 2) were chosen based on intrinsic and unique value. Participants (n = 46) were sampled using a combination of purposive and multi-level sampling. Data was analyzed using an iterative process; inductive coding was used to gain a sense of context followed by a deductive cross-case analysis to compare and contrast themes across sites. Kompier's five-step framework was used to assess factors contributing to successful implementation and to provide insight into interactions between teams, providers and patients. Both cases satisfied all five factors (systemic and gradual approach, identification of risk factors, theory-driven, participatory approach and sustained committed support). However, one case was more successful at fully implementing their model, attributed to a flexible implementation, plans to mitigate risks, theory use, a supportive team and continued buy-in from leadership. By better understanding key facilitators and barriers, we can support the implementation of chronic disease management programs, foster sustainability of high-performing interprofessional teams, and engage patients in the development and maintenance of team-based chronic disease management.
