OBJECTIVES: To investigate the provision of adult dental extraction under general anaesthesia (DGA) at the Royal Cornwall Hospitals NHS Trust (RCHT)-- specifically adult single tooth DGA episodes in regards to numbers, demographics, justifications, and appropriateness regarding the use of resources.
METHOD: Data were collected retrospectively from the patient case notes and electronic records for the complete study cohort. This study included all episodes of adult single tooth DGA in all RCHT sites during 2014, except for mandibular third molar and impacted teeth. Each case was tested against the DGA case selection criteria empirically devised for this study.
RESULTS: In 2014, 106 episodes of adult single tooth DGA were carried out in RCHT that met the inclusion criteria. Younger females from more socio-economically deprived areas of Cornwall were increasingly likely to have this procedure. Mental disorders were the most prevalent co-morbidity (21.7%) in this cohort. The vast majority of patients (93.4%) had previously tolerated dental treatment without the need for general anaesthesia (GA). Many referrals (46.2%) and listings (30.2%) specifically stated patient demand-driven reasons. None of the cohort had DGA due to failure of sedation. There were potentially 11 episodes that met the DGA case selection criteria. patients waited for 126 days (median) from the referral date for an operation which took seven minutes (median) to complete. The majority (83%) of the cases were simple exodontia. Twenty patients (18.9%) had previous DGA.
CONCLUSION: Potentially a considerable proportion of GA prescription appeared to be driven by patient demand rather than clinical need. This study poses a fundamental question--what drives the demand for DGA? National data collection and specific DGA case selection criteria are recommended.
