Changing use patterns of plasma volume expanders through educational intervention.
Use patterns of the plasma volume expanders albumin and hetastarch were evaluated before and after an educational program promoting the preferential use of hetastarch was implemented in a 700-bed teaching hospital. The high acquisition cost and periodic shortages of 5% albumin injection prompted the implementation in March 1985 of a target drug program that would encourage the use of 6% hetastarch injection in place of albumin whenever possible. Purchases of albumin and hetastarch were monitored from August 1984 to March 1985 and again from April to November 1985 to determine how much and where these agents were being used. Criteria and guidelines for the use of plasma volume expanders were developed by the pharmacy with physician input. Senior attending physicians who had been identified as primary decision makers in the clinical use of albumin were asked to abide by the guidelines; also, pharmacists conducted inservice educational programs on the use of hetastarch. Patterns of albumin and hetastarch use changed significantly (p less than 0.05) after the educational program was implemented. From August 1984 to March 1985, the mean number of units of albumin and hetastarch purchased monthly were 325.5 and 0.4, respectively. These numbers changed to 195.3 and 163.1 units, respectively, from April to November 1985. The monthly cost avoidance associated with this change was $5127, which extrapolates to $61,526 annually. An educational program can be effective in controlling hospital expenditures for plasma volume expanders. However, clinicians should be aware of the potential adverse effects of hetastarch and should avoid using it in excessive amounts or in patients with underlying coagulopathies.
