Impact of a pharmacist-directed pain management service on inpatient opioid use, pain control, and patient safety.

Purpose: To evaluate the impact of a pharmacy-directed pain management service (PPMS) designed to optimize analgesic pharmacotherapy, minimize adverse events, and improve patients' experience of pain management.
Methods: A retrospective analysis was conducted to evaluate the PPMS consisting of 3 dedicated pain management clinical pharmacists who perform both consult-based and stewardship functions. Multiple measures of opioid use and associated patient satisfaction outcomes during 3-year periods before and after implementation of the PPMS were compared.
Results: Significant decreases in use of institutionally defined high-risk opioid medications (e.g., parenteral hydromorphone, fentanyl, transdermal fentanyl patches), a decrease in total institutional opioid use, increased coanalgesic and adjunctive medication use, and a decrease in rapid response team (RRT) and code blue events associated with opioid-induced oversedation were seen after service implementation. Despite decreased opioid use, available patient satisfaction data suggested ongoing improvement in associated Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey domains.
Conclusion: Our data highlights the impact of a pharmacy directed pain management service on institutional opioid use with available data suggesting improved patient satisfaction scores and indirect cost savings. Despite decreased opioid use, available patient satisfaction data suggested ongoing improvement in associated HCAHPS survey pain management domains.
