Ciprofloxacin drug utilization review and prospective drug use evaluation.

Ciprofloxacin is a fluoroquinolone antimicrobial with activity against both gram-negative and -positive bacteria including pseudomonal and staphylococcal species. It is the only available oral agent possessing this unique spectrum of activity that achieves serum concentrations adequate to treat a variety of systemic infections. A retrospective drug utilization review and a prospective drug use evaluation of ciprofloxacin were performed to determine if the agent was being used for appropriate indications, to ensure correct dosing and appropriate monitoring, and to determine whether its use is cost effective at the Veterans Administration Medical Center, Cleveland (VAMCC). For the retrospective review, 40 patients' charts were randomly chosen for review from computerized inpatient and outpatient prescription records. Drug use review criteria were developed by the Pharmacy Service and Infectious Disease Section. For the prospective evaluation, data were collected for all inpatient and outpatient requests for ciprofloxacin during a six-month period (May to November 1988) using the same criteria as in the retrospective study. Cost analysis was performed by identification and cost comparison of alternative therapy and by estimating the number of days saved by using appropriate oral therapy. All charts from the retrospective review were found to meet criteria for appropriate use. All patients for whom documented follow-up was performed had microbiologic or clinical cures. In the prospective evaluation, 168 patients were started on ciprofloxacin. Ninety-five percent of patients had appropriate justification for use according to criteria. Drug cost savings for the six-month period was +14,962.54 or +29,925.08/year. This covered drug and minibag acquisition costs only. An estimated 127 hospital days were saved (shortened length of +71,717.00 or +143,434.00/year.(ABSTRACT TRUNCATED AT 250 WORDS)

Cost containment through P & T committee drug utilization review.

Provoked by changes that are occurring in health care, hospitals are currently formulating and implementing strategies to identify and control costs while maintaining the highest quality of care. Because drug costs account for a significant proportion of the hospital supply budget (5 to 10%), there is an increased need for the P & T Committee to become involved in the cost containment effort. This article will demonstrate how an existing program of drug utilization review (DUR) has reduced drug expenses without sacrificing the quality of care or imposing unnecessary restrictions on formulary items. Furthermore, implementation of the DUR program has not resulted in conflict between pharmacy, medical, nursing or administrative staffs within the institution.

The use of an antibiotic order form for antibiotic utilization review: influence on physicians' prescribing patterns.

An antibiotic order form was implemented for all inpatient antibiotic orders at an 800-bed hospital in April 1981 to provide an ongoing, concurrent audit of antibiotic use. The prescribing physician provided the clinical indication for the antibiotic order, and individual patient treatment courses were identified. During the 25-month study period, cephalosporins, penicillin plus ampicillin, and aminoglycosides accounted for 44%, 22%, and 17% of all treatment courses, respectively. Sixty-nine percent of first-generation cephalosporin treatment courses were for prophylaxis, whereas the remaining antibiotics were used for either empirical therapy or documented infection in 56%-79% of cases. After the introduction of the antibiotic order form, there was a significant decline in both the number of antibiotic treatment courses (P = .025) and the percentage of patients receiving any antibiotic (P = .007). We conclude that a specialized antibiotic order form is an effective method for antibiotic utilization review and can have a significant impact on a physician's prescribing patterns.

A utilization review of digoxin assays: sampling patterns and use.

A review of digoxin assay utilization concurrent with patient hospitalization was conducted at the University of Texas Medical Branch. An interdepartmental committee of clinicians adapted audit criteria for the collection and use of digoxin assays. This included rational indications, correct performance (i.e., collection and processing of serum sample) and appropriate dose adjustment. The charts of all patients receiving digoxin were examined daily, whether or not the physician had ordered a drug assay. Contributory data were collected and analyzed, including serum electrolyte concentrations, arterial blood gases, renal function tests, vital signs, physician assessments, and other information relating to pertinent and concomitant diseases or drug therapy. The 2-month review included 104 hospital inpatients who received 245 evaluations. Only 38.4% of the evaluations were determined to be compliant with all criteria. When the audit categories of rational indication, correct performance, and appropriate dosage adjustment were evaluated independently, compliance rates were 66%, 73% and 86%, respectively. In 108 cases (52%), the physicians provided inadequate instructions in their request for the digoxin assay to insure proper collection time by the phlebotomist. Approximately 94% of all assay results were verbally communicated to the physician or returned to the patients' charts for use in patient management within a minimum of 24 hours. Hospital laboratory charges for unnecessary, incorrectly performed, or inappropriately used digoxin assays were estimated to exceed $100,900 annually. The audit was used to demonstrate the need for changes in hospital procedures and house staff training. A collaborative pharmacokinetics service was organized with reimbursement accomplished through the physician billing charge.
