Impact of Adoption of Smart Pump System With Continuous Capnography Monitoring on Opioid-Related Adverse Event Rates: Experience From a Tertiary Care Hospital

摘要

Objectives The use of opioid analgesics for pain management in hospitalized patients is associated with a high risk of adverse events, including respiratory depression which may lead to respiratory arrest and death. Patients who experience opioid-related adverse drug reactions (ADRs) have been shown to experience longer and more costly hospital stays and have a higher risk of requiring a readmission after discharge. In this study, we report on the impact of the introduction of Wesley Medical Center's Safe Medication Practice Protocol on opioid-related ADRs. Methods A retrospective, pre-post cohort study using electronic health records combined with manual chart review was undertaken at the Wesley Medical Center, a 760-bed tertiary care facility. The Safe Medication Practice Protocol incorporating a smart infusion pump system with capnography monitoring was implemented in May 2010 hospital-wide. The number and severity of ADRs and the duration of opioid treatment were compared between the pre (2007-April 2010) and post (May 2010-2014) periods. Results A total of 139,734 (pre-period) versus 267,573 (post-period) patients received opioid treatment during the hospital stay. Compared with the pre-period, the post-period resulted in a 79.2% reduction in the number of severe adverse reactions (3.08 vs 0.64 per 10,000 patients treated with opioid,P< 0.0001) as well as a shorter duration of opioid treatment (average 2.05 vs 1.37 days,P< 0.0001). Conclusions Implementing education, revisions to patient-controlled analgesia policies and procedures, and capnography monitoring with patient-controlled analgesia pause is associated with significantly lower rates of severe ADRs and shorter opioid treatment duration.
