The basic characteristics of radiology practices in the United States are described. We defined radiology practices as diagnostic-radiology-only practices, either solo or multiradiologist practices. Findings were compared with those from other data sources.
In May 1999, the American College of Radiology surveyed 970 practices by mail using a 65-item questionnaire. A final response rate of 66% was achieved. Weighting was used to make responses representative of all radiology practices in the United States.
Approximately 4400 radiology practices existed in the country; 39% were located in nonmetropolitan or rural areas. The greatest percentage of practices (85%) was private nonacademic radiology practices. The greatest percentage of practices (43%) served only hospitals. However, solo practices were particularly likely (p < or = 0.01) to serve only nonhospital sites. Of all multiradiologist practices, 87% were completely owned by their members, but approximately two thirds of academic multiradiologist practices had outside owners. Seventy percent of multiradiologist practices interpreted images from outside clinics or groups; these averaged 3.2 outside clinics or groups for which they interpreted images.
The basic characteristics of radiology practices in 1999 are described. Good agreement was seen with findings obtained from other data sources.
描述美国放射科业务的基本特征。我们将放射科业务定义为仅从事诊断放射学的业务，包括单人执业或多名放射科医生共同执业。将研究结果与其他数据源的结果进行比较。
1999年5月，美国放射学会通过邮件向970家放射科业务机构发放了一份包含65个问题的调查问卷。最终回复率为66%。采用加权法使回复结果能够代表美国所有放射科业务机构。
美国约有4400家放射科业务机构；39%位于非大都市或农村地区。最大比例的业务机构（85%）为私立非学术性放射科业务机构。最大比例的业务机构（43%）仅服务于医院。然而，单人执业机构尤其可能（p≤0.01）仅服务于非医院场所。在所有多名放射科医生共同执业的机构中，87%完全由其成员所有，但约三分之二的学术性多名放射科医生共同执业机构有外部所有者。70%的多名放射科医生共同执业机构解读来自外部诊所或团体的影像；这些机构平均为3.2个外部诊所或团体解读影像。
描述了1999年放射科业务的基本特征。与从其他数据源获得的结果有良好的一致性。
