A survey of medical quality assurance programs in Ontario hospitals.
OBJECTIVE: To determine the prevalence and types of medical quality assurance practices in Ontario hospitals. DESIGN: Survey. SETTING: All teaching, community, chronic care, rehabilitation and psychiatric hospitals that were members of the Ontario Hospital Association as of May 1990. PARTICIPANTS: The person deemed by the chief executive officer of each hospital to be most responsible for medical administration. INTERVENTION: A questionnaire to obtain information on each hospital's use of criteria audit, indicators inventory, occurrence screening and reporting, and utilization review and management (URM) activities. OUTCOME MEASURES: Prevalence of the use of the quality assurance activities, the people responsible for the activities and the relative success of the URM program in modifying physicians' performance. RESULTS: Of the 245 member hospitals participants from 179 (73%) responded. Criteria audits were performed in 136 (76%), indicators inventory in 43 (24%), occurrence screening in 44 (25%), occurrence reporting in 61 (34%) and URM in 123 (69%). In-hospital deaths were reviewed in 157 (88%) of the hospitals. In all, 87 (55%) of the respondents from hospitals that had a URM program or were developing one indicated that their program was successful in modifying physicians' practices, and 29 (18%) reported that it was not successful; 26 (16%) stated that the effect was still unknown, and 16 (10%) did not respond. Seventy (40%) stated that results of tissue reviews were reported at least 10 times per year and 94 (83%) that medical record reviews were reported at least as often. The differences in the prevalence of the quality assurance activities between the hospitals were not found to be significant. CONCLUSIONS: Many Ontario hospitals are conducting a wide variety of quality assurance activities. Further study is required to determine whether the differences in prevalence of these activities between hospitals would be significant in a larger, perhaps national, sample. Strategies are needed to ensure universal involvement and participation in the improvement of the quality of care and the assessment of the cost-effectiveness of health care treatments. Recommendations to achieve these objectives are suggested.
