Resident physician performance in a continuing education format. Does newly acquired knowledge improve patient care?

As part of an educational program in preventive dentistry for family medicine residents, we evaluated changes in systemic fluoride prescribing habits related to newly acquired knowledge. Residents, unaware of the study, were randomly assigned to one of two groups and shown a videotape describing preventive dental techniques. We supplemented the tape viewed by one group with specific instructions explaining the implementation of the information in patient care. Residents in both groups demonstrated the ability to learn and maintain their level of knowledge during a three-month period. Daily chart audits, however, revealed no substantial increase in correct prescribing of systemic fluoride to pediatric patients for either group. Only subsequent individual monitoring and reinforcement achieved the desired behavior. The acquisition of new knowledge by resident physicians under these circumstances did not lead to its application in daily patient care. This result parallels reported difficulties in altering physician behavior by continuing medical education, and suggests that residency programs are an appropriate setting to initiate improved physician performance in response to acquired knowledge.
