Radiosurgery patterns of practice.

We distributed a questionnaire on radiosurgery patterns of practice to members of the International Stereotactic Radiosurgery Society (ISRS). Responses were obtained from physicians at 52 facilities, who had treated more than 13,000 patients. Most respondents were found to work within a multidisciplinary team, and averaged 17.3 specialist-hours devoted per patient on the day of radiosurgery. These results will enable radiosurgeons to determine if their practice differs from the norm and to adjust their practice standards, if appropriate.
