We proposed that computerized diagnostic and prognostic predictions from statistical models would improve the ability of medical housestaff to estimate outcomes in patients with coronary artery disease (CAD). Interns made estimates of the likelihood of significant CAD, three-vessel or left main CAD, and left main CAD. Then, they received immediate feedback from computerized statistical models that had been developed from a data base of over 10,000 patients evaluated at Duke University Medical Center. A control group of interns made similar predictions without exposure to the computerized model estimates. In addition, all interns made predictions on a set of historical case summaries both before and after the rotation. Measures of discrimination of diagnostic estimates were compared between the control and experimental interns and between the interns and the statistical models. Despite the superior predictive ability of the models, the experimental and control groups were similar in all aspects of their predictive abilities. For the historical case summaries, both groups improved their predictions on the more prevalent outcome of significant disease, but did not improve their estimation of severe disease during their one month rotation on the cardiology service. |
