| pubmed-article:2321658 | pubmed:abstractText | Medication prescribing patterns and costs of specific drug therapies in a trauma intensive-care unit (TICU) were studied. Demographic data and total drug use (scheduled, p.r.n., and single-dose medications) were recorded for all patients admitted to a TICU whose length of stay exceeded 24 hours. Scheduled and p.r.n. medications were categorized into major drug classes for purposes of analysis. Cost estimates were calculated for all scheduled medications. Correlations were made between demographic variables, injury severity indices, drug use, and length of stay by using simple linear regression. A one-way ANOVA was used to compare drug use between the trauma types. For the 278 patients who met the inclusion criteria, the mean +/- S.D. number of drugs prescribed was 9.1 +/- 6.5. Scheduled medications accounted for 58% of total drug use. Mean +/- S.D. duration of scheduled drug therapy was 5.0 +/- 4.8 days. Age (by decade), injury severity score, trauma score, and length of stay correlated with total and scheduled drug use per patient. Drug use (total, scheduled, and p.r.n.) did not differ significantly by trauma type. Antimicrobial therapy, stress ulcer prophylaxis, and bronchodilator therapy accounted for more than 66% of all scheduled drugs used; total cost estimates for these three drug categories exceeded $47,000 over the six-month study period. Analgesics, antipyretics, sedatives, and muscle relaxants constituted nearly 75% of all p.r.n. drug orders. Drug use in the TICU was extensive. The drug categories identified in this study may be useful in future cost containment efforts and initiation of drug use evaluations. | lld:pubmed |
