Institutions embarking on utilization endeavors require mechanisms to identify and quantitate institution-specific problems. This article describes, with examples, the application of a utilization hot line as a cost-effective tool to focus efforts and solve immediate problems.
The charts of 56 patients with chest pain who were admitted to the critical care units to rule out myocardial infarction were evaluated concurrently and retrospectively to compare the efficiency of cardiologists and internists. The number of unnecessary days used to rule out myocardial infarction, the number of unnecessary inhospital days used after ruling out myocardial infarction, the length of cardiac work-up, and the length of hospital stay were determined for 23 patients of cardiologists and 33 patients of internists. The cardiologists' patients had fewer unnecessary days after ruling out myocardial infarction (2.76 vs. 0.43 days, p less than .01) and a shorter length of hospital stay (5.15 vs. 2.91 days, p less than .02). We concluded that consideration should be given to increasing and refining the supplementary role of physician-experts to primary care physicians as one means of improved resource allocation.
Electrolyte (E) utilization by medical and surgical house staff in the critical care units of a community teaching hospital was audited over a two-month period. One hundred forty-five patients involved in 708 patient days had 924 sets of electrolytes (SE). Of the 581 SE that were ordered as an additional set within 24 h, 10% were considered unnecessary and 65% could have had a single E substituted for the complete set. The conclusion of this study and literature review are: (1) Electrolytes are excessively ordered in the management of critical care patients. (2) When additional electrolyte data is required within 24 h, a single electrolyte will usually suffice. (3) Misutilization is equally prevalent among medical house staff and surgical house staff. (4) The cost savings to be realized from improved laboratory utilization are only a small percentage of the potential savings in charges. (5) No single, proven modality has been identified which will consistently, continually, and appropriately decrease laboratory overutilization.
