To describe the hospital activities of radiology groups in the United States, including the characteristics of hospitals at which groups practice, workload and staffing at these hospitals, and groups' professional and business arrangements at these hospitals.
The American College of Radiology surveyed a stratified random sample of radiology groups, defining a radiology group as any practice with two or more radiologists or radiation oncologists, including private groups, academic or multispecialty groups, and staffs of government facilities. All groups were directed to complete a detailed, two-page hospital information sheet (HIS) for each hospital at which they practiced. Sixty-nine percent of groups responded, and we obtained HISs for 86% of their hospitals. These responses were weighted to make our results representative of all U.S. hospitals at which radiology groups practice.
Radiology groups reported performing on average 47,800 diagnostic procedures annually at hospitals. The average number of diagnostic procedures (inpatient plus outpatient) performed was 0.8 per inpatient day. This number varied greatly from hospital to hospital. A full-time equivalent (FTE) diagnostic radiologist at a hospital performed on average 11,400 procedures annually. Again, variation was large; the 25th percentile was 7000 procedures annually per FTE, and the 75th percentile was 14,100 procedures. Radiation oncology services were mainly provided at larger hospitals (more than 300 beds). On average, the annual number of new oncology patients at hospitals offering radiation oncology services was 380, and these patients received an average of 8435 fractions. Groups accepted nonreferred patients for mammography at 42% of hospitals at which they provided diagnostic services, and they provided 24-hr coverage for diagnostic radiology at 80% of the hospitals at which they provided diagnostic services.
Radiologists can use the findings from this survey to evaluate their hospital practice. The workload data show considerable variation, and averages should not be taken as standards.
描述美国放射科团队的医院活动，包括团队执业医院的特征、这些医院的工作量和人员配备，以及团队在这些医院的专业和业务安排。
美国放射学会对放射科团队进行了分层随机抽样调查，将放射科团队定义为任何由两名或更多放射科医生或放射肿瘤学家组成的执业机构，包括私人团队、学术或多专科团队以及政府设施的工作人员。所有团队都被要求为其执业的每家医院填写一份详细的两页医院信息表（HIS）。69%的团队做出了回应，我们获得了其86%的医院的HIS。对这些回复进行加权处理，以使我们的结果能够代表美国所有放射科团队执业的医院。
放射科团队报告称，其在医院每年平均进行47,800例诊断程序。诊断程序（住院加门诊）的平均执行数量为每住院日0.8例。这个数字在不同医院之间差异很大。医院一名全职等效（FTE）诊断放射科医生每年平均执行11,400例程序。同样，差异很大；第25百分位数是每年每FTE 7000例程序，第75百分位数是14,100例程序。放射肿瘤学服务主要在较大的医院（超过300张床位）提供。平均而言，提供放射肿瘤学服务的医院每年新肿瘤患者数量为380例，这些患者平均接受8435次分次治疗。在提供诊断服务的医院中，42%的医院团队接受未转诊的乳腺摄影患者，在提供诊断服务的医院中，80%的医院团队为诊断放射学提供24小时覆盖。
放射科医生可以利用本次调查结果评估其在医院的执业情况。工作量数据显示差异很大，不应将平均值作为标准。
