Selecting performance assessment methods for experienced physicians.

BACKGROUND: While much is now known about how to assess the competence of medical practitioners in a controlled environment, less is known about how to measure the performance in practice of experienced doctors working in their own environments. The performance of doctors depends increasingly on how well they function in teams and how well the health care system around them functions. METHODS: This paper reflects the combined experiences of a group of experienced education researchers and the results of literature searches on performance assessment methods. CONCLUSION: Measurement of competence is different to measurement of performance. Components of performance could be re-conceptualised within a different domain structure. Assessment methods may be of a different utility to that in competence assessment and, indeed, of different utility according to the purpose of the assessment. An exploration of the utility of potential performance assessment methods suggests significant gaps that indicate priority areas for research and development.

Oral terbinafine in the treatment of toenail onychomycosis: North American multicenter trial.

BACKGROUND: Onychomycosis is an increasing problem with limited therapeutic options. OBJECTIVE: We evaluated the safety and efficacy, of oral terbinafine, a new fungicidal antimycotic, in patients with toenail onychomycosis. METHODS: A North American multicenter, double-blind, placebo-controlled study evaluated the mycologic and clinical efficacy of oral terbinafine 250 mg/day for 12 or 24 weeks in 358 patients with toenail onychomycosis. RESULTS: A total of 74% of patients treated with 12 or 24 weeks of terbinafine achieved a successful clinical outcome. Approximately 11% of terbinafine responders showed evidence of relapse 18 of 21 months after cessation of treatment. Terbinafine was well tolerated; most adverse events were transient and mild to moderate in severity. CONCLUSION: The results of this study confirm that oral terbinafine is a safe and effective therapy for the treatment of onychomycosis.
