Barriers to Improving Pain Management in the Emergency Department: Lessons from a Lean-Driven Quality Improvement...

Background/Objectives: Pain remains as a prevailing cause, prompting patients to seek medical attention, comprising approximately 40% of all emergency department (ED) visits annually. Timely and effective pain management is crucial for patient comfort, satisfaction, and optimal recovery. However, there is increasing evidence highlighting the concern that patients often receive inadequate pain management in both emergency departments and prehospital settings. Despite the simplicity and potential for the repetitive use of pain scales throughout a patient's stay, it appears that a greater emphasis is often placed on monitoring hypotension or low saturation values rather than addressing pain levels above 7 on the numeric rating pain scale. Methods: This article represents an ambitious attempt to implement process improvement methodologies such as Lean Management and SixSigma, both which have been well established in service and industrial fields, within the hospital environment to improve the process of pain management in the emergency department. Results: The implementation of pain management improvement processes in the emergency department led to a statistically significant but clinically modest increase in the administration of analgesics and improved pain reporting practices. The percentage of patients receiving no analgesia decreased from 96.6% to 94.8% (p = 0.008), and the documentation of pain characteristics during triage improved. However, the escalation of pain therapy remained limited, and strong analgesics were still underutilized. Conclusions: Despite partial improvements, the lean management-based interventions did not sufficiently address the problem of oligoanalgesia in the emergency setting. Sustainable change requires enhanced clinical engagement, ongoing staff training, and the broader adoption of structured analgesia protocols across prehospital and hospital care.
