In a prospective, randomized study, 110 adults receiving aminogly-cosides were randomized to follow-up by a clinical pharmacokinetic service (CPS). Of the 110 patients, 35 accepted pharmacokinetic recommendations less than 100% of the time. The two groups were similar in age, sex, height, APACHE II score, and initial creatinine clearance. A cost-to-charge ratio was used to derive direct costs of hospitalization and calculate cost-benefit. Patients whose physicians accepted pharmacokinetic recommendations 100% of the time had shorter hospitalizations (322.67 ± 270.28 h; CPS <100%, 699.54 ± 806.35; p = 0.001) and febrile periods (50.05 ± 79.38 h; CPS <100%, 120.00 ± 153.23; p = 0.002). Acceptance of CPS recommendations led to adequate peak levels. Acceptance of CPS recommendations led to lower direct costs (7,102.56 ± 9,898.19; CPS <100%, 19,629.94 ± 28,051.89; p <0.001). Calculated direct cost of the service was 85/patient.
