Effectiveness and Feasibility of Patient Controlled Analgesia in the ED

Study Summary

Background: Inadequate pain management is common in the Emergency Department (ED). Optimal treatment of pain necessitates titration to effective dose due to the large inter-individual variability in opioid requirement. However nurse administered titration is difficult to provide in this setting due to high patient to nurse and physician ratios and multiple urgent competing patient demands. Patient controlled analgesia (PCA) lets ED patients actively participate in pain management by allowing self-titration to their desired level of pain relief. A tightly controlled randomized clinical trial (RCT) funded by the National Institute of Nursing Research (NINR) recently completed by the investigators group provides promising preliminary support for the efficacy and safety of PCA for patients with abdominal pain at a single ED with a dedicated research nurse and standard loading dose given to all patients. Objective: The overall objective is to provide optimal pain management in the ED. Specific aims: 1)To compare the effectiveness and safety of PCA and non-PCA opioid analgesia when nurses involved in clinical care deliver the intervention to a broad group of ED patients with acute pain at multiple clinical centers. The primary hypothesis is that there will be a greater decline in pain over time and similar safety in patients randomized to receive PCA compared to patients receiving standard opioid analgesia. 2) To describe the feasibility of PCA in terms of patient and provider acceptance, resource utilization and cost associated with PCA. Innovation: PCA represents a novel shift from the current provider-driven model of ED pain management to one in which the patient is an active participant. Few prior studies have evaluated ED PCA and no systematic evaluation of time and resources exists. Methodology: An RCT will be performed at 3 clinical centers. 750 patients with acute pain warranting IV opioid administration will be randomized to receive usual opioid analgesia determi
