Abstract

PURPOSE

To determine radiologists' workloads in 2006-2007, as measured by both procedures per full-time equivalent (FTE) radiologist and relative value units (RVUs) per FTE radiologist, and to discover trends since 1991-1992.

MATERIALS AND METHODS

Non-individually identifiable data from the American College of Radiology (ACR) 2007 Survey of Radiologists were compared with data from previous ACR surveys; all surveys were weighted to make them nationally representative. Under National Institutes of Health rules for protection of human subjects, studies based on anonymized surveys do not require approval by an institutional review board. Workload according to individual practice characteristics, such as type (eg, academic, private, multispecialty) and setting, was tested for statistically significant differences from the average for all radiologists. Time trends and the independent effect on workload of practice characteristics were measured with regression analyses. Changes in average procedure complexity were calculated in physician work RVUs per Medicare procedure.

RESULTS

In 2006-2007, the average annual workload per FTE radiologist was 14,900 procedures, an increase of 7% since 2002-2003 and 34.0% since 1991-1992. Annual RVUs per FTE radiologist were 10 200, an increase of 10% since 2002-2003 and 70.3% since 1991-1992. Academic practices performed about one-third fewer procedures per FTE radiologist than others. In most types of practice, radiologists in a 75th-percentile practice performed at least 65% more procedures annually than radiologists in a 25th-percentile practice. Regression analysis showed that practices that used external off-hours teleradiology services performed 27% more procedures than otherwise similar practices that did not use these services.

CONCLUSION

Radiologists' workload continued to increase in recent years. Because there is much unexplained variation, averages or medians should not be used as norms. However, such statistics can help practices to understand how they compare with other, similar practices.

摘要

目的

通过每位全职等效（FTE）放射科医生的检查程序数量以及每位FTE放射科医生的相对价值单位（RVU）来确定2006 - 2007年放射科医生的工作量，并发现自1991 - 1992年以来的趋势。

材料与方法

将美国放射学会（ACR）2007年放射科医生调查中的不可识别个人数据与ACR以往调查的数据进行比较；所有调查均经过加权处理，使其具有全国代表性。根据美国国立卫生研究院关于保护人类受试者的规定，基于匿名调查的研究无需机构审查委员会的批准。针对根据个体执业特征（如类型，例如学术型、私人型、多专科型）和环境的工作量，测试其与所有放射科医生平均水平的统计学显著差异。通过回归分析测量时间趋势以及执业特征对工作量的独立影响。根据医疗保险程序中每位医生工作RVU计算平均检查程序复杂性的变化。

结果

在2006 - 2007年，每位FTE放射科医生的年均工作量为14,900例检查程序，自2002 - 2003年以来增加了7%，自1991 - 1992年以来增加了34.0%。每位FTE放射科医生的年度RVU为10200，自2002 - 2003年以来增加了10%，自1991 - 1992年以来增加了70.3%。学术型执业机构每位FTE放射科医生的检查程序数量比其他机构少约三分之一。在大多数执业类型中，处于第75百分位的执业机构的放射科医生每年进行的检查程序比处于第25百分位的执业机构的放射科医生至少多65%。回归分析表明，使用外部非工作时间远程放射学服务的执业机构比未使用这些服务的类似执业机构多进行27%的检查程序。
