Comparative evaluation of the effect of a high yield criteria list upon skull radiography.
Based on results of studies using high yield criteria to determine the need for skull radiography, the Utilization Review Committee of the University Hospital (UH), University of Washington, Seattle implemented a policy encouraging use of the criteria in ordering skull radiology. The Bureau of Radiologic Health of the FDA supported a project comparing skull radiology use patterns at UH, with the high yield criteria policy, and Harborview Medical Center (HMC), without a policy. Results showed an increase of around 60% at HMC since the 1972--73 academic year. At UH, there was a decrease of 40% since the 1972--73 academic year. At HMC a medical record review showed only 51 positive reports that significantly contributed to patient care, about the same rate observed in 1967. At the UH, only nine positive reports significantly contributed to patient care, with 62% compliance with the high yield criteria. A current demonstration project under the auspices of the Washington State Professional Standards Review Organization and Bureau of Radiologic Health involves implementing the high yield criteria list at both HMC and UH. After three months, out of 6,003 patient visits, skull radiography was deemed necessary in 518 cases. Of this total 181 had high yield criteria checked. There were 37 positive reports out of these and 23 examinations that made a documented significant contribution to patient care. In the group without high yield criteria, 434 cases, there were 22 positive reports but no significant contribution to patient care documented after four weeks.
