A gentamicin order form improves its use.

To assess the effects of implementing a standardized order form on the prescribing and monitoring of gentamicin sulfate at a nonteaching Veterans Affairs Medical Center, we prospectively evaluated the prescribing and monitoring of gentamicin for 14 months after the use of such a form was implemented. The data collected included dosing, initial serum gentamicin concentrations, and serum creatinine measurements. These data were compared with similar data obtained during a period of 6 months before the order form was used. A total of 76 patient records were reviewed, 39 before the use of the order form and 47 after the order form was implemented. Gentamicin peak concentrations were statistically higher in the group treated after the order form was implemented. No differences were seen in gentamicin trough concentrations. The timely measurement of serum gentamicin concentrations and serum creatinine levels was improved in the group for whom the order form was used. The order form was completed satisfactorily in 44 patients (94%). We conclude that implementing a standardized order form improved the use of gentamicin.
