A trial of the use of bar code technology to restructure a drug distribution and administration system.

As we move into the 1990s, the challenges we face are many. Our ever-changing health care industry is giving managers, directors, and administrators much to ponder: how do we reduce costs and improve patient care? One promising area that may help answer this question in pharmacy services is bar code technology. This article offers helpful advice about the development of bar code and drug delivery systems and discusses the future applications of bar code technology in pharmacy practice, based on 3 years of hands-on experience at Florida Medical Center.

Changing prescribing patterns: a program of physician education.

A drug utilization review identified significant inappropriate use of second-generation cephalosporins at a 700-bed community teaching hospital. As a result, an educational program designed to modify physician prescribing patterns was developed as a cost-containment measure. Educational guidelines listing indications and contraindications for cefamandole and cefoxitin and comparing their costs with those of first-generation cephalosporins were placed in patient records, and physician use of these agents was reviewed before, during, and after the intervention. The rate of combined appropriate use of cefamandole and cefoxitin increased from 30 to 58% during the study. A change from the second-generation cephalosporins to therapeutically equivalent, less-expensive drugs was noted in 28% of patients' medical records within 48 hours after placement of the guidelines. This educational program proved to be a low-cost method of successfully altering the prescribing patterns of physicians.

Ethanol, disulfiram, and pyrazole: effects on interferon production in mice.

The effects of ethanol alone or combined with pyrazole or disulfiram were studied in reference to interferon production. Saline, ethanol (2 g/kg), pyrazole (2 mg/kg), or disulfiram (2 mg/kg) were injected, intraperitoneally, 3 hr after poly I:C, an interferon inducer. Drugs were administered either by a single injection, or twice daily for 7 days, and the mice were sacrificed 6 hr after poly I:C. Sera from mice were pooled, dialyzed, and assayed for interferon by the microplaque reduction method. Administration of ethanol alone reduced interferon production 76% and 66% after the single and the multiple injections, respectively. A similar inhibition of interferon occurred after either pyrazole or disulfiram, with a greater potency for pyrazole. Treatment with pyrazole prior to ethanol reduced interferon production further, but only after the 7-day schedule. All drugs tested affected cellular immunity as measured by interferon production. Moreover, reduced interferon production by these agents was associated with a loss of splenic lymphoid tissue, suggesting that ethanol, pyrazole, and disulfiram could affect susceptibility to viral infection.
