OBJECTIVES:To assess whether the joint review of radiologic studies by the primary care physician and the radiologist affects patient care and health care costs. DESIGN:Prospective study. SETTING:Student health clinic at a university hospital. PATIENTS:University students seen during acute care visits. INTERVENTION:Joint weekly review of all radiologic studies ordered at the student health clinic between July 1992 and June 1993 by a staff radiologist and internist. MEASUREMENTS AND MAIN RESULTS:The outcome measures were: (1) change of radiologic diagnosis after review process and its effect on patient management; (2) expenses saved or incurred by the review process. Of 323 films ordered, 305 were reviewed, resulting in revisions of 23 (8%) of the initial readings. Sixteen revisions (5%) led to a change in patient management; the remainder were clinically insignificant. In these 16 cases, cancellation or simplification of further workup resulted in savings of $1,967. The cost for extra physician time was $5,499. Thus, the review process incurred a net cost of $3,532. Except for the reduction in diagnostic studies, no therapeutic benefit for the patients could be identified. Film readings in our radiology department were conservative, with a positive predictive value of 85% and a negative predictive value of 99.7%. CONCLUSIONS:Routinely reviewing every radiologic study did not affect patient outcome in an outpatient clinic with low prevalence of disease. Given our radiologists' conservative film-reading practice, a review of only abnormal studies may prove more cost-effective in a healthy population. This type of assessment has implications for improving the efficiency of a changing health care system.
