Barriers and facilitators to health visiting teams delivering oral health promotion to families of young children: a mixed methods study with vignettes

Objective: To explore the potential barriers and facilitators to health visiting (HV) teams delivering oral health promotion during the 9-12-month old child mandated visit in Ealing, England. Background: HV schemes and their counterparts worldwide share similar priorities to discuss oral health at 6-12 months of age. The HV programme in England stipulates at 9-12 months old, diet and dental health should be discussed. HVs believe dental decay is important however oral health knowledge is varied. Further, little is understood about what drives HVs to deliver oral health advice. An appropriate theoretical model to explore these factors is the Theoretical Domains Framework (TDF). Methods: An opportunistic sample of HV team members was drawn from three hubs to allow for maximum variation. First, participants completed a questionnaire to establish baseline knowledge. Secondly, participants were invited to take part in focus groups (FGs) with vignettes. Thirdly, face-to-face interviews were conducted. FGs were subject to thematic analysis and the interviews to framework analysis. Results: Thirty-six participants provided written informed consent and completed baseline questionnaires. Three FGs were conducted with an average of seven participants (n=21) followed by 13 interviews. Perceived facilitators: good levels of knowledge and skills, sense of professional role, emotions, belief in capability, organisational structure and resources. Perceived barriers: gaps in knowledge, conflicting advice from other professionals, conflicting issues for parents/carers, use of interpreters. Conclusions: These findings can be harnessed to support oral health promotion delivered by HV teams.
