This study uses self-reports from a nationwide sample of 5447 physicians in ten medical and surgical specialties to assess the impact of on-site facilities on the use of radiologic examinations by non-radiologists. Data from 169,559 patient visits show that when on-site radiologic facilities are available to non-radiologists, radiographs increase by a factor of 1.2 (internal medicine) to 1.7 (pediatrics). Use of radiologic examinations is up to four times greater for hospitalized compared with nonhospitalized patients and is slightly higher for hospital-based physicians and for younger physicians.
本研究采用了来自全国范围内10个医学和外科专业的5447名医生的自我报告，以评估现场设施对非放射科医生使用放射检查的影响。来自169559次患者就诊的数据显示，当非放射科医生可以使用现场放射设施时，X光片的使用量在内科增加了1.2倍，在儿科增加了1.7倍。与非住院患者相比，住院患者的放射检查使用量高出四倍，并且对于医院医生和年轻医生来说，使用量略高。
