in a Family Practice Residency Training Program Adrienne Z. Ables, PharmD; Otis L. Baughman III, MD Background: According to a recent survey, 27% of 579 family practice residency programs in the UnitedStates employ a full-time clinical pharmacist. The majority of pharmacists’ time is spent teaching, usuallyat the point of care either on inpatient rounds or precepting in the outpatient clinic. This paper describesthe precepting activity of a full-time clinical pharmacist in a community-based family practice residencytraining program. Methods: A computer program written in Microsoft Access® captured the followingdata on each pharmacist-physician encounter: date, time, requestor, topic, therapeutic category, type ofquestion, summary of question and answer, resources used to answer the question, and time spent answer-ing the question. The database was updated daily to include all encounters. Results: Between February 1,1999, and January 31, 2001, we documented 2,260 precepting encounters. Almost half of the questionsrelated to general pharmacotherapeutic management of chronic or acute diseases. The most commontherapeutic categories encompassed cardiovascular, psychiatric, infectious disease, and neurologic dis-orders. Seventy-six percent of questions were answered using clinical knowledge and experience, while24% were based on published resources. Conclusions: Based on more than 2,000 precepting encountersbetween a faculty pharmacist and family practice residents, most encounters represented requests byresidents for information on general drug management of diseases. The pharmacist answered most ques-tions based on clinical knowledge and experience. Evaluations of the pharmacist by the residents indi-cated that she is an effective teacher and useful in helping take care of patients. With the increasing numbers of medications brought in 49% of the interventions, and there was an average to the US market every year and the publication of nu- cost avoidance of $154 per intervention. Mason and merous studies on those medications, attainment and Colley, in a study involving two general medicine clin- application of succinct pharmacotherapeutic informa- ics, showed that the number of potential drug problems tion is a challenge. Clinical pharmacists are in a unique identified per patient was significantly greater in a clinic position to complement physicians in the application without pharmacist intervention, while the number of of evidence-based pharmacotherapy and cost-effective beneficial interventions implemented was significantly greater in a pharmacist-staffed clinic.2 A cost savings The contribution of clinical pharmacists in ambula- of $185 per intervention was calculated. Finally, a ran- tory clinics has been described. Hatoum et al reported domized, controlled trial of elderly outpatients taking on 199 pharmacotherapeutic interventions made by four five or more chronic medications demonstrated that clinical pharmacists in 1 month.1 Types of recommen- inappropriate prescribing decreased significantly in dations included adding or changing a drug, changing patients whose regimens were reviewed by and inter- a dose, educating the prescriber, suggesting or discon- vened on by a clinical pharmacist, and the patients ex- tinuing laboratory orders, discontinuing a drug, clari- perienced fewer adverse drug events.3 In all three of fying or correcting a prescription, and changing a drug the aforementioned studies, physicians accepted the regimen. Positive patient outcomes were documented majority of the pharmacist’s recommendations. Indeed,in a study by Haxby et al, family physicians found 97%of pharmacist consultations useful, and 77% of the phy-sicians believed that the consultation enhanced the clini-cal outcome of their patients.4 Fro m t h e Sp art an b urg Fam i l y Med i ci n e Res i d en cy Pro g ram ,Spartanburg, SC.
