Incorporation of pharmacist pre-surgical calls to improve medication history completion rates.

Abstract

The accuracy and timeliness of documenting a medication history is an important aspect to ensure appropriate medication reconciliation during transitions of care. Surgical patients often have their medication history recorded just moments before surgery which may be rushed, incomplete or missed entirely. Between January and May 2020, 76.7% of surgical patients admitted to our institution had a medication history completed by a pharmacist prior to surgery. The objective of this work is to improve the pharmacist medication history completion rates for pre-surgical patients before surgery by integrating pharmacist-led medication histories into the pre-operative pathway. Through interdisciplinary collaboration, the pre-operative pathway for surgical patients was evaluated for opportunities to complete medication histories days prior to their scheduled procedure. Plan-Do-Study-Act (PDSA) cycles were utilized to make incremental improvements in practice. Through an iterative process, the pathway for cardiovascular surgery (CVS) patients was modified to include a scheduled pharmacist phone appointment in the days leading up to their surgical procedure. Utilizing these phone appointments, pharmacists complete patient medication history reviews and share a feedback loop to cardiovascular and peri-operative health care providers. The iterative PDSA cycles revealed challenges to completing pre-surgical medication history calls without advance notice. Patient responsiveness to pre-surgical medication history calls improved with the incorporation of scheduled phone appointments. Between January 18 and May 31, 2021, pharmacists completed 359 of 376 scheduled CVS appointments (95.5%), improving the medication history completion rates for cardiovascular surgery patients from 84.8 to 93.0% (p = 0.000025). The completion rate for all surgical patients also improved from 76.7 to 85.1% (p<0.00001). Incorporating scheduled pharmacist medication history appointments as a part of the pre-operative pathway was shown to expand the capacity for pharmacists to complete medication histories for patients prior to surgery. By reducing pharmacist workload on the morning of surgery, fewer patients were admitted to surgery without having their medication history reviewed by pharmacy. Future investigation should be considered to evaluate the impact on patient outcomes.
