Primary healthcare provider-perceived barriers to implementing an evidence-based pathway for undifferentiated lower gastrointestinal tract symptoms: A qualitative inquiry

Background Primary healthcare providers play a critical role in diagnosing and managing digestive disorders. Standardized clinical care guidelines have been developed, but with limited and inconsistent implementation. An evidence-based gastroenterology clinical care pathway (GUTLINK) has been proposed in one region of Canada; however, little is known in the medical literature about potential barriers to pathway implementation within primary care. We aimed to identify behavioral and environmental barriers and facilitators to implementation of evidence-based care pathways for undifferentiated lower gastrointestinal tract symptoms in primary care. Methods One-on-one semi-structured interviews were conducted with primary healthcare providers between September 2021 and May 2022. Interview script development was guided by the COM-B framework. Interviews were transcribed and data were analyzed using an inductive thematic analysis approach. Results A total of 15 primary healthcare provider interviews were conducted. Several key barriers to GUTLINK implementation were identified in all three domains of the COM-B framework. Key barriers included Capability (e.g., Physician Knowledge and Access to Allied Health), Opportunity (e.g., Access to diagnostic tools), and Motivation (e.g., Comfort with managing cases and optimism). Some of these barriers have not previously been identified in medical literature. Conclusions Evidence-based clinical care pathways have the potential to support access to quality gastroenterology care, yet primary healthcare providers in this study identified several barriers to implementation. Potential solutions exist at the individual and clinic levels (e.g., greater education, improved provider-specialist communication), but must be supported with systems-level changes (e.g., increased funding for gastrointestinal care and e-Health platforms) to support pathway implementation and improve quality of care.
