A Clinical Vignette-Based Study of Physicians' Adherence to Guidelines for Dental Referrals of Young Children

The American Academy of Pediatrics (AAP) recommends an oral health risk assessment and referral to a dental home by a child's first birthday. We evaluated the adherence of primary care providers (PCPs) to AAP dental referral guidelines for children age <4 years and barriers to implementation of these guidelines.

A cross-sectional survey of PCPs randomly selected from the 435 practices in North Carolina identified as providing well-child visits for Medicaid children age <4 years was completed in 2013. The PCPs' referral recommendations were assessed using 4 vignettes of 18-month-old children at various risk of dental caries (low, moderate, high, or highest) and different levels of dentist supply (adequate or inadequate). Barriers to guideline adherence specified in the Cabana framework were analyzed for their associations with PCP adherence, using logistic regression models stratified by caries risk and dentist supply.

The survey yielded 219 (50%) usable responses from the sample of 435 PCPs. On average for all vignettes, 61% of providers chose a referral recommendation in agreement with guidelines. Underreferral averaged 40%. With adequate workforce, guideline-adherent responses varied from 26% for low-risk children to >90% for high-risk children. An inadequate workforce reduced adherence for most levels of risk. Generally, correct knowledge of risk status, barriers to risk assessment, and pediatric practice were associated with adherence, but not always in the hypothesized direction.

PCPs' adherence to referral guidelines varies according to caries risk and dentist supply, but generally they underrefer low- to moderate-risk patients by a significant degree.
