COST-CONTAINMENT IN THE USE OF LOW-OSMOLAR CONTRAST AGENTS - EFFECT OF GUIDELINES, MONITORING, AND FEEDBACK MECHANISMS

PURPOSE: To describe a program for controlling intravenous use of low- osmolar contrast agents (LOCAs). MATERIALS AND METHODS: The department of radiology at the authors' institution adopted a policy of selectiv e use of intravenously administered LOCAs. Clinical indications for LO CA use were specified after consultation with the administration, risk managers, legal department, and ethics committee of the hospital. The guidelines were then publicized throughout the department and hospita l, and a contrast agent data form was developed to collect data on all cases. Monitoring mechanisms were instituted. RESULTS: Over the next 23 months, 11,373 patients received intravenous iodinated contrast age nts, of whom 28.1% were deemed to be at high risk and were given LOCAs . Monthly tracking showed no evidence of a trend toward increasing use of LOCAs. CONCLUSION: Clear definition of use guidelines, close monit oring, and feedback can stabilize LOCA use at acceptably low levels.
