Facilitators and Barriers to the Implementation of BETTER WISE, a Chronic Disease and Prevention Intervention in Canada: A Qualitative Study

The aim of the BETTER WISE intervention is to address cancer and chronic disease prevention and screening (CCDPS) and lifestyle risks in patients aged 40–65. The purpose of this qualitative study is to better understand facilitators and barriers to the implementation of the intervention. Patients were invited for a 1-h visit with a prevention practitioner (PP), a member of a primary care team, with specific skills in prevention, screening, and cancer survivorship. We collected and analyzed data from 48 key informant interviews and 17 focus groups conducted with 132 primary care providers and from 585 patient feedback forms. We analyzed all qualitative data using a constant comparative method informed by grounded theory and then employed the Consolidated Framework for Implementation Research (CFIR) in a second round of coding. The following key elements were identified: (1) Intervention characteristics—relative advantage and adaptability; (2) Outer setting—PPs compensating for increased patient needs and decreased resources; (3) Characteristics of individuals—PPs (patients and physicians described PPs as compassionate, knowledgeable, and helpful); (4) Inner setting—network and communication (collaboration and support in teams or lack thereof); and (5) Process—executing the implementation (pandemic-related issues hindered execution, but PPs adapted to challenges). This study identified key elements that facilitated or hindered the implementation of BETTER WISE. Despite the interruption caused by the COVID-19 pandemic, the BETTER WISE intervention continued, driven by the PPs and their strong relationships with their patients, other primary care providers, and the BETTER WISE team.
