Evaluation of oral chemotherapy prescribing at an outpatient oncology clinic.

Abstract

191 Background: Oral chemotherapy’s exponentially increasing role in the treatment of malignancies continues to pose unique challenges to oncology. The American Society of Clinical Oncology (ASCO) and Oncology Nursing Society (ONS) drafted measures in the Chemotherapy Administration Safety Standards that help address some of these issues concerning oral chemotherapy. There is a lack of data describing the prescribing process for oral chemotherapy. In a retrospective chart review, prescriptions at a hospital-based outpatient oncology center were evaluated for completeness of prescribing and follow up measures. Methods: A retrospective chart review of ten oral chemotherapy medications from May 2012 to July 2012 was conducted. The primary outcome measure was compliance with ASCO and ONS Chemotherapy Administration Safety Standards. A secondary outcome was frequency of pharmacist interventions on oral chemotherapy prescriptions. Results: 412 prescriptions were evaluated. Prescriptions were graded on a scale from 1 to 8. One point was given for inclusion of each of the following: prescribing physician, patient name, drug name, dose, dosing methodology, quantity, refills, and accurate directions. Of all the prescriptions, 23% contained all aspects of a complete prescription. The most common reasons for point deductions were contradictory or unclear directions and allowing refills for oral chemotherapy which should not be refillable. Four percent of prescriptions had a documented pharmacist intervention. Conclusions: This study revealed areas for improvement in the prescribing process of oral chemotherapy. Targeting directions and refill fields within prescription templates will improve compliance with ASCO and ONS standards. This can be accomplished by implementing customized oral chemotherapy prescription templates within treatment plans in the electronic medical record system. Unlike chemotherapy administered in the clinic setting, oral chemotherapy prescriptions are not generally reviewed by oncology trained pharmacists. With the collaboration of medical and nursing staff, a new work flow was implemented which includes pharmacist review of electronic oral chemotherapy prescriptions.
