An educational program for hospital pharmacists in and near Vermont is described and its impact on departmental clinical practice evaluated. Pharmacists were instructed by practitioners from a single institution in basic pharmacokinetics, practice guidelines for aminoglycoside therapy, and use of a computer program for aminoglycoside dosage determination. Participants completed a multiple-choice precourse test, a similar postcourse test, and a third test six months after class completion. Test scores were compared with those from a control group of pharmacists. Pharmacy directors from study group hospitals completed questionnaires measuring aminoglycoside clinical services before and six months after the program. Compared with the control group, participants scored higher on the postcourse tests. Results from the questionnaire indicate that the program affected clinical practice in almost all participating pharmacy departments. A consistent pharmacokinetic strategy for reviewing aminoglycoside dosages and evaluating serum aminoglycoside concentrations is now practiced in most Vermont hospitals. An educational program originating in one hospital can expand pharmacists' knowledge and influence departmental clinical practice throughout a region.

The relationship between creatinine clearance changes during gentamicin therapy and several patient and therapeutic variables was studied in a prospective, multicenter trial. Adult patients in three hospitals who were receiving gentamicin in doses based on lean body weight and creatinine clearance were studied. Pre- and post-therapy serum creatinine measurements were obtained for 62 patients (Group 1); only 45 of the patients had both pre- and post-therapy creatinine clearance measurements (Group 2). Other data collected for correlation with creatinine clearance changes were: body temperature, age, sex, blood pressure, albumin level, previous and concomitant therapy with nephrotoxic drugs, hematocrit, peak and trough gentamicin levels, and duration of therapy. In Group 2 patients, only peak gentamicin level, concomitant therapy, sex, and previous furosemide therapy correlated significantly (p less than or equal to 0.05) with change in creatinine clearance during gentamicin therapy. The first two variables decreased creatinine clearance, the last variable increased creatinine clearance, and women tended to have more of a decrease in clearance than did men. Sex, peak gentamicin level, prior furosemide therapy and concomitant cephalothin therapy explain about 50% of the renal function changes during gentamicin therapy, and should be considered in monitoring gentamicin therapy.
