Canadian nurse initiated analgesia protocol to reduce delays in the emergency department: A quality improvement study

Background

Australian literature supports nurse-initiated opioid analgesia protocols may be effective, but this practice is not yet widely adopted in Canada.

Local problem

Previous quality audits of Emergency Departments (EDs) in Victoria (Canada) indicate long delays to administration of analgesia.

Methods

Two tertiary care hospitals in a Canadian city of approximately 400,000 people were chosen for a quality improvement initiative. A manual retrospective chart review was conducted on a total of 122 patients which was compared to data from 125 patients from a previous audit in 2019.

Interventions

ED nursing staff both hospitals were provided education and daily reminders to document pain score at triage, and to flag an acute analgesia opioid order set on the charts of patients with moderate or severe pain (greater than 4 out of 10 in the Numerical Rating Scale (NRS) or by triage nurse’s clinical judgment). At Victoria General Hospital (VGH), nurses had the option of finding an emergency physician (EP) to sign the acute analgesia opioid order set, or independently administer IV opioids from a presigned order set without consulting an EP. At Royal Jubilee Hospital (RJH), nursing staff could only administer IV opioids from the order set after an EP was consulted. Median time to opioid analgesia after the intervention was compared to 2019 data for each hospital.

Results

Each hospital significantly reduced median time to administration of opioids: VGH achieved 45.6 % reduction (1 h 8 min improvement, p = 0.001) and RJH achieved a 62.5 % reduction (2 h 11 min improvement, p < 0.001). Secondary outcomes indicated patients may receive analgesia faster when the opioid protocol was nurse initiated (median 43 minutes) vs physician initiated (median 1 h 1 min) at VGH. Pain score documentation at triage improved from <10 % in 2019 to >50 % in 2020 at both sites. Approximately 95 % of EP and nursing staff thought nurse-initiated opioids are safe, effective, and should be supported by regulatory boards.

Conclusion

Implementing a new triage protocol to expedite initiation of an analgesic protocol was associated with significantly reduced time to analgesia for patients with moderate to severe pain. Time reductions may be greater with nurse-initiated analgesia before physician assessment.
