description Objective To examine the oral health conditions and oral health behaviour of high-cost patients and evaluate oral health measures as predictors of future high-cost patients.Design A retrospective, population-based cohort study using administrative healthcare records.Setting The National Health Insurance Service (NHIS) medical check-up database (a.k.a. NHIS—national health screening cohort database) in South Korea.Participants 131 549 individuals who received biennial health check-ups including dental check-ups in 2011 or 2012, aged 49–88.Primary outcome measures Current and subsequent year high-cost patient status.Results High-cost patients, on average, incur higher dental costs, suffer more from periodontal disease, brush their teeth less and use secondary oral hygiene products less. Some of the self-reported oral health behaviours and oral symptom variables show statistically significant associations with subsequent year high-cost patient indicators, even after adjusting for demographic, socioeconomic, medical conditions, and prior healthcare cost and utilisation.Conclusions We demonstrate that oral health measures are associated with an increased risk of becoming a high-cost patient.
