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.
描述1995年美国放射学团体以及不同执业类型放射科医生的特征。
向3024名放射科医生发放调查问卷，回复率为75%。对回复进行加权处理以代表所有美国团体或放射科医生。
共有3285个团体，其中340个是学术性团体，356个是多专业团体。50%的团体有两至四名成员；39%的放射科医生所在团体成员少于八名，8%为个体执业者。所有放射科医生中，70%受雇于完全由执业医生拥有的医疗机构，其中80%的人本身就是所有者。8%的放射科医生受雇于政府所有的医疗机构，15%（主要是学术性的）受雇于所有医生均为雇员的私立医疗机构。69%的学术诊断放射科医生主要从事一个领域的工作，但在非学术团体中这一比例仅为22%。个体诊断执业者通常业务范围也较广，但不包括高成本的检查方式。非学术团体的放射科医生平均休假天数（每年30天）多于学术团体（每年19天）或个体执业者（每年12天）。个体执业者和临时代理执业者年龄相对较大，学术放射科医生年龄相对较小。
截至1995年，团体平均规模增长缓慢。不同执业类型之间存在重要差异，尤其是学术性和非学术性执业之间。
