Medical Record Alert Associated with Reduced Opioid and Benzodiazepine Co-prescribing
The 2014 VA Opioid Safety Initiative (OSI) prioritized reductions in opioid and benzodiazepine co-prescribing and other non-recommended opioid prescribing practices. This implementation project evaluated the effectiveness of an advanced medication alert designed to reduce opioid and benzodiazepine co-prescribing among Veterans with high-risk conditions (substance use disorder, sleep apnea, suicide risk, and age >e; 65) at one VA healthcare system (VA Puget Sound). Primary outcomes were population-level changes in the proportion of patients co-prescribed opioids and benzodiazepines in the 12 months before and after alert launch for each of the four risk conditions. Alert site trends were compared to those of a similar VA healthcare system without the alert. Secondary outcomes included: 1) change in proportion of patients with each risk condition prescribed opioids before and after alert launch; 2) change in proportion of patients with each risk condition prescribed benzodiazepines before and after alert launch; and 3) among patients activating the alert, changes in prescribing patterns in the 6 months after patients' initial alert activation.
- Proportions of patients with concurrent prescriptions decreased significantly post-alert launch among Veterans with substance use (25%), sleep apnea (39%), and suicide risk (62%), with greater decreases at the alert site relative to the comparison site in sleep apnea and suicide-risk cohorts. Significant decreases in benzodiazepine prescribing were observed at the alert site only.
- Over 12 months, the alert activated for 1,332 Veterans, activating a median of 3 times per patient, with the most common reason for activation being age, followed by sleep apnea and substance use disorder – and small numbers (<5%) for suicide risk.
- Most long-term users (≥ 90 days of both medications in prior 6 months) with an activated alert continued to be co-prescribed these medications six months later.
- Future work should examine whether combining medication alerts with other interventions (e.g. greater availability of behavioral supports for tapering and/or pain management, academic detailing) further decreases risky medication combinations.
- Efforts that involve multiple prescriber groups (e.g. primary care and mental health) may lead to greater reductions in co-prescribing than involvement of a single group.
- Investigators could not determine whether the medication alert resulted in cancelled benzodiazepine or opioid prescriptions, as these data were not available.
- Investigators were unable to capture all prescriptions received outside VA.
