Abstract

Objective: Compare time to pain relief (minimum of a 13 mm and 30% reduction) during an Emergency Department (ED) visit among patients with sickle cell disease (SCD) experiencing severe pain associated with a vaso-occlusive episode who were randomized to receive either an individualized or weight-based pain protocol. Methods: A randomized controlled trial in two EDs. Adults with sickle cell disease. Research staff recorded pain scores every 30 min during an ED visit (up to 6 h in the ED) using a 0–100 mm visual analogue scale. Analysis included 122 visits, representing 49 patients (individualized: 61 visits, 25 patients; standard: 61 visits, 24 patients). Results: Pain reduction across 6-h was greater for the individualized compared to the standard protocol (protocol-by-time: p =.02; 6-h adjusted pain score comparison: Individualized: M = 29.2, SD = 38.8, standard: M = 45.3, SD = 35.6; p =.03, Cohen d = 0.43). Hazards models indicated a greater probability of 13 mm (HR = 1.54, 95% CI = 1.05, 2.27, p =.03) and 30% (HR = 1.71, 95% CI = 1.11, 2.63, p =.01) reduction in the individualized relative to the standard protocol. Conclusions: Patients who received treatment with an individualized protocol experienced a more rapid reduction in pain, including a 13 mm and 30% reduction in pain scores when compared to those that received weight-based dosing.
