Barriers and facilitators at pre-implementation of a type 2 diabetes screening program in dental care using the consolidated framework for implementation research and the theoretical domains framework.

Abstract

Screening and referral for type 2 diabetes mellitus (T2DM) during dental care visits has the potential for expanding preventive care. Using the consolidated framework for implementation research (CFIR) and the theoretical domains framework (TDF), we examined the barriers and facilitators at pre-implementation of a community-driven T2DM screening program in an urban dental clinic serving Alaska Native and American Indian (AN/AI) adults. This convergent mixed-methods parallel study was informed by the updated CFIR. Data were collected in 2023 through a 13-item survey of adult AN/AI potential recipients of the T2DM screening innovation/intervention, and individual in-person interviews with dental and primary care providers, staff, and operational leaders who were from the population of potential innovation deliverers. Univariate statistics and differences between strata were analyzed using R software. Interview transcripts were coded onto CFIR and TDF domains using template analysis then thematically analyzed. A convergent analysis identified areas of convergence, divergence, or complementarity. Two hundred and fifty potential innovation recipients provided survey responses. The majority of survey respondents agreed that the dental clinic is a good place to get T2DM screening, thought screening would be helpful, and had no concerns about the setting. Some respondents had concerns about T2DM screening in the dental setting or by dental staff due to T2DM screening not usually occurring in a dental visit. However, most survey respondents thought the dental clinic as a good place to get screened for diabetes and had low levels of concern about T2DM screening in dental settings. Primary care providers did not see the need for T2DM screening in dental settings; however, about half of potential innovation recipients thought the T2DM screening information would be helpful for their doctor and would be a good way to find if they were at risk for or currently had T2DM. Using CFIR and TDF, we identified barriers and facilitators to inform the design of a pilot process, development of pilot materials, and selection of innovation deliverers.
