Abstract

Background: A controlled substance agreement (CSA) is a risk mitigation strategy for patients managed on controlled substance medications such as opioids and benzodiazepines. Limited literature exists to describe the role of the clinic pharmacy team to promote adherence to CSA monitoring parameters.  

Objective: The objective of this study is to evaluate the impact of interprofessional educational and clinical interventions led by an ambulatory care pharmacist on adherence to monitoring parameters within a CSA policy. 

Methods: This retrospective observational study included patients on long-term controlled substances who had a clinic visit every 3 months during the study period. The primary outcomes were the proportion of patients with a signed CSA in the electronic medical record (EMR), urine drug screen (UDS) completion, and documentation of review of the statewide prescription drug monitoring program (PDMP) in the EMR 8 months prior to as compared to 8 months after implementation of pharmacist interventions. 
Results: Among 79 patients (mean age 55.7 years, 65.8% female, 54.4% African American), 8.9% pre- vs 88.6% post-interventions had a signed CSA (p<0.001), 35.4% pre- vs 65.8% post-interventions had a UDS completed (p<0.001), and 32.9% pre- vs 57% post-interventions had documentation of PDMP review (p=0.002).

Conclusion: Adherence to monitoring parameters within a CSA policy significantly improved after educational and clinical interventions led by an ambulatory care pharmacist.
