Observational, Retrospective Evaluation of a New Nurse-Initiated Emergency Department Pain Management Protocol

Background: Triage nurses are important in pain management and in early relief of pain among patients admitted to the emergency department (ED).

Aims: To assess a new nurse-initiated pain management protocol, without the requirement for medical prescription, wich was implemented in October 2016 for patients with moderate or severe pain in the ED. It allows the administration of oral acetaminophen and oral oxycodone chlorydrate during the first evaluation of the patient by a nurse and eliminates the use of codeine or tramadol.

Methods: We conducted a comparative, single-center, retrospective study that looked at the outcomes of a new nursing protocol for patients aged ≥16 years with moderate to severe pain. The primary outcome was the percentage of increase of analgesics delivered by the nurse.

Results: A total of 756 patients were included: 377 before and 379 after protocol implementation. Oral analgesic use on admission increased from 44.3% to 57.8% (p < .001), and from 50.2% to 76.6% among patients with severe pain (p < .001). Strong opioid analgesic administration increased from 2.1% to 41.2%. This increase was also observed among those with moderate pain (1.4% to 13.3%; p < .001) and those with severe pain (2.6% to 62.6%; p < .001). Analgesic prescriptions added by the clinician decreased from 28.6% to 21.4% (p = .028).

Conclusions: We observed an increase in analgesic administration after the implementation of a new nurse-initiated pain treatment protocol, especially an increase in oral opioid analgesics, for patients with moderate to severe pain.
