A qualitative exploration of decisions about dental recall intervals-Part 1: attitudes of NHS general dental practitioners to NICE guideline CG19 on the interval between oral health reviews

Introduction The National Institute for Health and Care Excellence (NICE) Guideline CG19 recommends that the intervals between oral health reviews should be tailored to patients' disease risk. However, evidence suggests that most patients still attend at six-monthly intervals. Aim To explore facilitators and barriers to the implementation of CG19 in general dental practice. Methods Semi-structured telephone interviews were conducted with 25 NHS general dental practitioners (GDPs) in Wales, UK. Transcripts were thematically analysed. Results Dentists described integrating information on clinical risk, patients' social and dental history, and professional judgement when making decisions about recall interval. Although most GDPs reported routinely using risk-based recall intervals, a number of barriers exist to recall intervals at the extremes of the NICE recommendations. Many practitioners were unwilling to extend recall intervals to 24 months, even for the lowest-risk patients. Conversely, dentists described how it could be challenging to secure the agreement of high-risk patients to three-month recalls. In addition, time and workload pressures, the need to meet contractual obligations, pressure from contracting organisations and the fear of litigation also influenced the implementation of risk-based recalls. Conclusions Although awareness of the NICE Guideline CG19 was high, there is a need to explore how risk-based recalls may be best supported through contractual mechanisms.
