Abstract
OBJECTIVE: To determine whether prior authorization of topical tretinoin for acne is in the best interest of health insurers and, if so, to determine the optimal prior authorization age for topical tretinoin. STUDY DESIGN: A retrospective, cross-sectional study of data from the National Ambulatory Medical Care Survey was performed. PATIENTS AND METHODS: We performed a sensitivity analysis using published data on the age distribution for topical tretinoin prescriptions for acne and nonacne indications to estimate the cost of topical tretinoin and the cost of performing prior authorizations as a function of the prior authorization age. RESULTS: A prior authorization age of 25 for topical tretinoin is not cost effective for health insurers. If prior authorization is required, an age threshold of 35 or older is most cost effective. The total cost of topical tretinoin (the sum of the drug costs plus the prior authorization costs) changes little with changes in the prior authorization age; if the prior authorization age is set too low, total costs increase (because the number of prior authorizations increase). CONCLUSIONS: Prior authorization for topical tretinoin is of no great benefit to insurers. As the prior authorization age decreases, the cost of requiring prior authorization increases. Eliminating prior authorization altogether would result in at most a small increase in costs and would be balanced by the benefits to both patients and physicians.
