BackgroundVaso-occlusive crises (VOCs) cause debilitating pain and are a common cause of emergency department (ED) visits, for people with sickle cell disease (SCD). Strategies for achieving optimal pain control vary widely despite evidence-based guidelines. We tested existing guidelines and hypothesized that a patient-specific pain protocol (PSP) written by their SCD provider may be more effective than weight-based (WB) dosing of parenteral opiate medication, in relieving pain.MethodsThis study was a prospective, randomized controlled trial comparing a PSP versus WB protocol for patients presenting with VOCs to six EDs. Patients were randomized to a PSP or WB protocol prior to an ED visit. The SCD provider wrote their protocol and placed it in the electronic health record for future ED visits with VOC exclusion criteria that included preexisting PSP excluding parenteral opioid analgesia or outpatient use of buprenorphine or methadone or highly suspected for COVID-19. Pain intensity scores, side effects, and safety were obtained every 30 min for up to 6 h post-ED bed placement. The primary outcome was change in pain intensity score from placement in an ED space to disposition or 6 h.ResultsA total of 328 subjects were randomized; 104 participants enrolled (ED visit, target n = 230) with complete data for 96 visits. The study was unable to reach the target sample size and stopped early due to the impact of COVID-19. We found no significant differences between groups in the primary outcome; patients randomized to a PSP had a shorter ED length of stay (p = 0.008), and the prevalence of side effects was low in both groups. Subjects in both groups experienced both a clinically meaningful and a statistically significant decrease in pain (27 mm on a 0- to 100-mm scale).ConclusionsWe found a shorter ED length of stay for patients assigned to a PSP. Patients in both groups experienced good pain relief without significant side effects.© 2023 Society for Academic Emergency Medicine.
