  1. Characteristics of radiology groups and of diagnostic radiologists and radiation oncologists in different types of practices.

    Article - En anglais


    To describe the characteristics of U.S. radiology groups and of radiologists in different types of practices in 1995.


    A survey was distributed to 3,024 radiologists ; the response rate was 75%. Responses were weighted to represent all U.S. groups or radiologists.


    There were 3,285 groups ; 340 were academic, and 356 were multispecialty.

    Fifty percent of groups had two to four members ; 39% of radiologists were in groups with fewer than eight members, and 8% were solo practitioners.

    Seventy percent of all radiologists were in practices owned entirely by physicians in the practice, and 80% of these were themselves owners.

    Eight percent of radiologists were in government-owned practices, and 15% (primarily academic) were in privately-owned practices in which all physicians were employees.

    Sixty-nine percent of academic diagnostic radiologists worked primarily in one field, but this was true of only 22% of those in nonacademic groups.

    Solo diagnostic practitioners also typically had a broad practice but excluded high-cost modalities.

    Radiologists in nonacademic groups averaged more vacation days (30 d/yr) than academic (19 d/yr) or solo (12 d/yr) practitioners.

    Solo and locum tenens practitioners were relatively old ; academic radiologists, relatively young.


    Through 1995, average group size has grown slowly.

    There are important differences among practice types, especially between academic and nonacademic practices.
