Measuring the cost, effectiveness, and cost-effectiveness of orthodontic care.
OBJECTIVE
To determine the relative effectiveness and cost-effectiveness of orthodontic treatment per case in one "fee for item" and two different types of salaried orthodontic clinics.


METHODS
This prospective study recruited a random sample of six self-employed orthodontists (fee-for-item) and six orthodontists from both hospital and community clinics (salaried services). One hundred patients were followed to completion of orthodontic care. Questionnaires were employed to determine cost of treatment from the clinicians' and patients' points of views. Four cost-effectiveness models were developed.


RESULTS
Complete records of outcome were available for 1,087 patients, but only 789 had complete data on costing. Three of the four cost-effectiveness models indicated similar rankings for the 18 clinicians. The most cost-effective service was provided by clinicians working in community clinics, followed by clinicians working in hospitals, then self-employed clinicians. The preferred cost-effective model takes into consideration the initial need and successful outcome of orthodontic treatment.


CONCLUSIONS
Cost-effectiveness models have been developed to quantify the performance of individual clinicians working in self-employed and salaried clinics. Costs and effectiveness of the clinicians in each clinical setting show considerable variation.
