Alexandra AC Boudreau: Caregiver Characteristics Associated with Physician-Based Preventive Oral Health Services (PB-POHS) (Under the direction of Jessica Lee) BACKGROUND: Most states have adopted Physician-Based Preventive Oral Health Services (PB-POHS) to address challenges related to the oral health care for young children. Our aims were to describe caregiver and child characteristics of children who received PB-POHS versus those who did not, while comparing characteristics of children receiving the optimal number of PB-POHS to those not. METHODS: We examined a cohort of 1,405 child-caregiver dyads enrolled in the Carolina Oral Health Literacy (COHL) Study. Caregivers completed a structured interview and each child's Medicaid medical, dental and hospital claims for the three-year period of study was evaluated. RESULTS: Our analytical sample included 831 children. Sixty-four percent received PB-POHS; only 11% received the optimal number of visits. Other than county of residence, there were no significant differences in caregiver characteristics among recipients and non-recipients of PB-POHS. CONCLUSIONS: PB-POHS programs may overcome the traditional barriers to dental care noted in the literature.
