title: Radiation oncologists in the United States.
abstract: OBJECTIVE
  To provide an extensive and detailed portrait of radiation oncologists, their professional activities, and the practices in which they work.
  
  
  METHODS
  We analyzed non-individually identified data from the American College of Radiology's 2003 Survey of Radiation Oncologists, a stratified random sample survey that guaranteed respondents' confidentiality and achieved a 68% response rate, with a total of 472 responses. Responses were weighted to make them representative of all radiation oncologists in the United States. We use two-tailed z tests of percentages and means to compare information from the current survey with those from a similar 1995 survey.
  
  
  RESULTS
  The number of posttraining, professionally active radiation oncologists grew from nearly 2900 in 1995 to nearly 3500 in 2003, an increase of approximately 21%. Twenty-three percent of posttraining, professionally active radiation oncologists were women. Among posttraining, professionally active radiation oncologists, 95% were board-certified. Forty-eight percent of radiation oncologists were in nonacademic, radiation-oncology-only private practices; 20% in academic practice; 14% in nonacademic, multispecialty practices; and 11% in solo practice. The largest percentage of radiation oncologists worked in the South (34%). The average annual number of patients treated (curative and palliative) per radiation oncologist was 264. On average, radiation oncologists preferred a 4% increase in their workload. The proportion of radiation oncologists planning a career change decreased from 8% in 1995 to 4% in 2003, and in 2003 34% said they were enjoying radiation oncology more than 5 years earlier, compared with 21% in 1995.
  
  
  CONCLUSIONS
  Despite concerns in 2003 about lower-than-optimal workload, professional satisfaction, if anything, increased since 1995.
