  • Title: Prompting for cost-effective test ordering: a randomized controlled trial.

    Journal: Proc Annu Symp Comput Appl Med Care; 1995; ():635-9. PubMed ID: 8563364.
    Abstract:
    This randomized, controlled trial tests the efficacy of a computerized prompting system for test ordering. The system, makes use of the sensitivity, specificity, positive and negative predictive values of tests. It was tested using clinical vignettes in an academic family medicine center with first and second year residents. We found that there was a 38% decrease in the numbers of tests ordered (p < .01) and a 12% decrease in the costs of tests ordered by using the prompting system. We suggest that when used at the point of the patient encounter, this system has the potential for promoting more appropriate test ordering and for saving considerable health care dollars.
