Ionizing radiation therapy in dermatology. Current use in the United States and Canada

Abstract

A comprehensive survey of the Task Force on Ionizing Radiation of the National Program for Dermatology was answered by 2,444 dermatologists in the United States and Canada (53.6% of 4,560 questionnaires). Computer analysis of the data showed that 55.5% of dermatologic offices are equipped with superficial x-ray machines and/or grenz ray units and that 44.3% of dermatologists use superficial x-ray or grenz rays regularly. Most respondents (65.8%) favor increased practical instruction in radiotherapy in training programs. A majority (63.4%) want examinations in radiation therapy by the American Board of Dermatology continued or increased. Data dealing with training in radiation therapy, reasons for non-utilization, alternate care, radiation safety, and economic considerations are presented in detail. Common indications for superficial x-ray therapy and grenz ray therapy are listed in order of frequency and percentage of use.
