OBJECTIVE:To determine whether a brief, multicomponent intervention could improve the skin cancer diagnosis and evaluation planning performance of primary care residents to a level equivalent to that of dermatologists.
PARTICIPANTS:Fifty-two primary care residents (26 in the control group and 26 in the intervention group) and 13 dermatologists completed a pretest and posttest.
DESIGN:A randomized, controlled trial with pretest and posttest measurements of residents' ability to diagnose and make evaluation plans for lesions indicative of skin cancer.
INTERVENTION:The intervention included face-to-face feedback sessions focusing on residents' performance deficiencies; an interactive seminar including slide presentations, case examples, and live demonstrations; and the Melanoma Prevention Kit including a booklet, magnifying tool, measuring tool, and skin color guide.
MEASUREMENTS AND MAIN RESULTS:We compared the abilities of a control and an intervention group of primary care residents, and a group of dermatologists to diagnose and make evaluation plans for six categories of skin lesions including three types of skin cancer-malignant melanoma, squamous cell carcinoma, and basal cell carcinoma. At posttest, both the intervention and control group demonstrated improved performance, with the intervention group revealing significantly larger gains. The intervention group showed greater improvement than the control group across all six diagnostic categories (a gain of 13 percentage points vs 5, p Ͻ .05), and in evaluation planning for malignant melanoma (a gain of 46 percentage points vs 36, p Ͻ .05) and squamous cell carcinoma (a gain of 42 percentage points vs 21, p Ͻ .01). The intervention group performed as well as the dermatologists on five of the six skin cancer diagnosis and evaluation planning scores with the exception of the diagnosis of basal cell carcinoma. I n the United States, managed care organizations currently rely on primary care physicians to triage for many specialized areas of medicine, including dermatology. Successful triaging involves screening, making correct initial diagnosis and evaluation planning decisions, and appropriately referring to specialists. Because many of these managed care organizations use financial incentives and administrative mechanisms to encourage generalists to limit referrals to specialists, 1 we must ensure that primary care physicians can screen, diagnose, and evaluate effectively with reduced access to specialists. In dermatology, primary care physicians may not need to be as skilled as dermatologists at diagnosing and planning treatment for the approximately 2,000 named skin diseases, 2 but, at a minimum, they need to proficiently screen, diagnose, and evaluate lesions indicative of skin cancer. 3 In this study, we focused on improving primary care residents' performance on diagnosing and making evaluation plans for lesions indicative of skin cancer.
CONCLUSIONS:Primary care physicians have the opportunity to play a major role in the early detection of skin cancer. Up...
