Estimating treatment and treatment times for special and nonspecial patients in hospital ambulatory dental clinics

Increased time to treat the special patient is often cited as a barrier to dental care. The purpose of this study was to analyze the separate and combined effects of differences in dental services planned, services actually performed, and differences in treatment time requirements between special and nonspecial patients in a hospital ambulatory clinical setting. Data for this study were obtained from the UCLA evaluators of the RWJ-funded Hospital-Sponsored Ambulatory Dental Services Program (HSADSP). The results show that special patients require more dental treatment than nonspecial patients for advanced dental disease (i.e., periodontics, surgery, and removable prosthetics) and that they receive more of such services. The study also found that special patients should not be viewed as a homogeneous group when evaluating dental needs and required time resources for treatment. Three subgroups of special patients were identified: developmentally disabled, severely compromised, and moderately compromised. The developmentally disabled as compared to the nonspecial patients required significantly more (20 percent) provider time in completing a "representative" treatment plan.
