IMMUNE GLOBULIN USE AT A MULTIHOSPITAL MEDICAL-CENTER

Use of i.v. immune globulin (IVIG) at four hospitals was audited to evaluate the need for therapeutic protocols and identify strategies for reducing drug expenditures. Charts and nursing notes for patients who received IVIG over a six-month period were reviewed retrospectively to obtain the following data: patient demographics, indication for IVIG use, product used, amount administered, and adverse reactions. Indications were categorized as to whether they are included in FDA-approved labeling, recognized in national guidelines, documented in published studies, or not documented. Expenditures were calculated from acquisition costs. At the first hospital (which offers oncology and other specialty services for adult patients), 71 patients received IVIG for 15 indications, with 89.5% of the orders for unlabeled uses. Of atl grams reconstituted, 17.8% were wasted. The rate of documented adverse reactions was 11.3%. At the second, a pediatric hospital, 34 patients received IVIG for six indications, with 65% of the orders for unlabeled uses. Of all grams reconstituted, 13% were wasted. At the third hospital (which specializes in emergency trauma and critical care medicine), two patients received IVIG for a labeled indication. At the fourth (a maternity hospital), no patients received IVIG. Three of four hospitals used IVIG during a six-month audit period. In most instances, the drug was used for indications not included in FDA-approved labeling. Audit information may be useful in creating guidelines for appropriate use of IVIG.
