Clinical pharmacist impact on parenteral cephalosporin prescribing

A study was undertaken to evaluate clinical pharmacist influence on parenteral cephalosporin prescribing patterns. Two intervention methods were evaluated: (1) publication of pharmacy newsletter for physicians containing specific recommendations and emphasizing the primary use of cefazolin, and (2) personal interaction between the clinical pharmacy staff and physicians promoting the recommendations outlined in the newsletter. These two methods were compared with each other as well as with an initial time span during which no influencing efforts were made. The effect of the pharmacy newsletter as a sole means of influencing physician prescribing of parenteral cephalosporins was minimal. The effect of pharmacist-physician interaction, either as a sole means of in conjunction with a pharmacy newsletter, resulted in an increased use of cefazolin. An annual cost savings of up to $11,265.88 was projected. The results indicate that physicians can be influenced in their prescribing of parenteral cephalosporins, leading to significant cost savings.
