Abstract

Background/Objectives: Early detection of undiagnosed prediabetes (PD) and type 2 diabetes (T2D) could prevent or delay the onset of diabetes and its complications. The dental setting has been suggested as a location for expanding diabetes screening in primary care. This study aimed to investigate behavioural factors that influence an oral healthcare professional’s (OHP) participation in diabetes screening and their decision to refer individuals at a high risk of diabetes for medical follow-up and confirmatory diagnosis. These factors provide targets for future interventions to encourage screening implementation and increase referral guideline compliance. Methods: This qualitative study utilised OHPs who had participated in a diabetes screening trial in Victoria, Australia. Qualitative, semi-structured interviews were conducted by telephone or videoconferencing and transcribed and analysed thematically. The themes identified were deductively mapped onto the Capability, Opportunity, Motivation, and Behaviour (COM-B) model and the Theoretical Domains Framework (TDF). Results: In total, eight interviews were conducted (seven dentists and one oral health therapist). Five COM-B domains were identified: reflective motivation, automatic motivation, social opportunity, physical opportunity, and psychological capability. Nine TDF domains were associated with issues related to knowledge, the environmental context and resources, memory, attention and decision processes, skills, social influences, beliefs about consequences, emotion, beliefs about capability, and social influence. Conclusions: This is the first study to investigate the factors influencing an OHP’s participation and decision making in diabetes screening and referral processes in the dental setting. The results demonstrate that OHPs need more education and training to screen for diabetes in dental clinics. This study represents the first step in developing interventions to target these factors and improve the effectiveness of diabetes screening in the dental setting.
