OBJECTIVE

Our objectives were to describe the characteristics of "mixed practices"-that is, practices performing both diagnostic radiology and radiation oncology services-and to compare mixed practices with multiradiologist diagnostic radiology-only practices.

MATERIALS AND METHODS

In 1999, the American College of Radiology surveyed 970 practices by mail, using a 65-item questionnaire. A response rate of 66% was achieved. Responses were weighted such that they were representative of all the radiology practices in the United States. The estimates cited in this article were primarily drawn from this 1999 survey.

RESULTS

Mixed practices were nearly evenly divided between large (area population, > or = 1 million) and small metropolitan areas (area population, from 50,000 to 1 million). We found that 63% of mixed practices were nonacademic private practices; 27% were academic. Approximately 50% contained 15 or more members. Mixed practices were predominantly owned by members of the practice and predominantly served both hospitals and nonhospital settings. At least 90% of mixed practices performed mammography, imaging-guided breast biopsy, sonography, and nuclear medicine. We found that compared with multiradiologist diagnostic radiology-only practices, mixed practices were larger and were more likely to be academic, to serve both hospital and nonhospital settings, and to perform interventional and nuclear medicine procedures.

CONCLUSION

The characteristics of a mixed practice differ from those of a multiradiologist diagnostic radiology-only practice.

目的

我们的目的是描述“混合业务”的特征，即同时提供诊断放射学和放射肿瘤学服务的业务，并将混合业务与仅由多名放射科医生组成的诊断放射学业务进行比较。

材料与方法

1999年，美国放射学会通过邮件向970家业务机构发放了一份包含65个条目的问卷。回复率为66%。对回复进行了加权处理，使其能够代表美国所有的放射学业务机构。本文引用的估计数据主要来自于这项1999年的调查。

结果

混合业务在大城市（地区人口≥100万）和小都市地区（地区人口5万至100万）之间的分布几乎均匀。我们发现，63%的混合业务是非学术性私人业务；27%是学术性的。大约50%的混合业务包含15名或更多成员。混合业务主要由业务机构的成员所有，主要服务于医院和非医院机构。至少90%的混合业务开展乳房X线摄影、影像引导下乳房活检、超声检查和核医学检查。我们发现，与仅由多名放射科医生组成的诊断放射学业务相比，混合业务规模更大，更有可能是学术性的，服务于医院和非医院机构，并且开展介入和核医学程序。
