Hospital-based utilization management: a cross-Canada survey.

Utilization management attempts to measure, understand and, when appropriate, reduce hospital use. We conducted a telephone survey to determine the status of utilization management in Canadian hospitals. The sample comprised a random selection of 30% of acute-care hospitals with over 100 beds for adults in Ontario and Quebec and all such hospitals in the other provinces. Of the 123 chief executive officers contacted 99 (80%) claimed to have a utilization management program. Of those, 90 (91%) agreed to participate in an in-depth survey or to designate a senior administrator to be interviewed who was most knowledgeable about the program. High occupancy rates and funding issues were the most common environmental triggers for the development of utilization management programs; funding issues were listed more frequently by respondents in Ontario than by those elsewhere (p = 0.0008). Retrospective review alone was used in half of the hospitals, concurrent review or some mixed approach being used in the other half. Ontario and the Atlantic provinces were more reliant than the rest of the country on retrospective review alone (p = 0.0032). Most of the hospitals used peer review and education to stimulate corrective action. Of the respondents 67% indicated that the medical staff supported the utilization management program, and 53% reported that the program had a positive impact on the relationship between administrative and medical staff. Most of the respondents were unsure of the program's impact on the quality of care or the rate of unnecessary hospital admission. However, retrospective review alone was found to be less successful in reducing inappropriate utilization than either concurrent review or combined review (p = 0.0048).
