A model for dental workload measurement.

The primary purpose of the study was to develop a model that would provide an efficient and standardized approach to workload reporting in a non-fee (HMO-like) dental care system. The model was also designed to predict the dental personnel resource requirements in the system as the overall dental needs of the population were already known. To accomplish this, a set of 246 task/procedures representing the broad scope of dental practice was developed. For each task/procedure, a Best Time-weighted Estimate (BTE) in terms of average expected man-minutes of work required for accomplishment was developed from over 35,000 actual time measurements on patient visits to 29 US Army dental clinics located throughout the United States. Because of the nature of the specific task/procedure data, it was necessary to use four different mathematical models to produce statistically optimal BTEs. It was concluded that, cumulatively the BTEs developed for each task/procedure evaluated could be used as a basis for both the development of a Dental Care Composite Unit workload measure and the determination of overall dental personnel resource requirements in a non-free dental care system.
