Abstract
In Alberta, Canada, pharmacists have been granted the ability to prescribe most medications independently after completing an additional authorization process. While there are data to support the use of pharmacists' prescribing in the community setting, little is known about its use in the inpatient hospital setting. To describe the prescribing patterns of pharmacists in an inpatient setting including the percentage of pharmacists using their prescribing authority, the care areas where prescribing occurred, and the frequency of prescribing. Secondary objectives included describing the medications prescribed, and to determine if pharmacists are documenting their prescribing interventions. A descriptive, retrospective, cross-sectional study of medications ordered by pharmacists through the electronic order entry system in Calgary, Alberta, Canada. Prescriptions were examined in the context of how often each pharmacist prescribed, the medications prescribed, and an audit of documentation practices was performed using patient charts. A total of 64,293 orders from 172 pharmacists were included in the analysis, of which 51% (n = 32,681) were discontinuation orders. It was found that 90% of pharmacists used their prescribing authority, ordering a median of 11.3 prescriptions monthly (interquartile range 4.3-32.8). Clinical areas with the most overall prescribing included critical care (854.8), oncology and palliative care (463.0), and surgery (409.3) prescriptions per pharmacist Full-Time Equivalent per year. This study demonstrates a broad range of prescribing from pharmacists within acute care practice and a wide variety of medication prescribed. Future areas for research include barriers and enablers to pharmacist prescribing and examination of where prescribing pharmacists have the greatest value.
