Health services research.

The major barriers to the collection of primary population-based dental services data are: (1) Dentists do not use standard record systems; (2) few dentists use electronic records; and (3) it is costly to abstract paper dental records. The value of secondary data from paid insurance claims is limited, because dentists code only services delivered and not diagnoses, and it is difficult to obtain and merge claims from multiple insurance carriers. In a national demonstration project on the impact of community-based dental education programs on the care provided to underserved populations, we have developed a simplified dental visit encounter system. Senior students and residents from 15 dental schools (approximately 200 to 300 community delivery sites) will use computers or scannable paper forms to collect basic patient demographic and service data on several hundred thousand patient visits. Within the next 10 years, more dentists will use electronic records. To be of value to researchers, these data need to be collected according to a standardized record format and to be available regionally from public or private insurers.
