Cost-effectiveness of Two Painkillers for Treating Pain After Limb Injuries
Summary
Background: Paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are commonly used oral analgesics in emergency departments (ED) not only in Hong Kong but throughout the world. There are no large-scale (n\>100), prospective, randomised studies comparing paracetamol with ibuprofen in the management of acute soft tissue injury. As paracetamol is cheaper than most NSAIDs, may be as effective in the management of acute pain and possibly with fewer adverse effects, a large-scale, randomised, controlled trial is needed to answer questions of relative analgesic efficacy, safety and cost-effectiveness. Previous comparative studies on NSAIDS have been done in this unit and have suggested equivalence between two NSAIDs and paracetamol, but numbers were small and drug doses were modest. Objective: To compare the efficacy, safety and cost between oral ibuprofen and paracetamol in pain control for acute soft tissue injuries in an ED setting Design: Prospective, double-blind, randomised controlled trial with three arms: oral paracetamol with placebo; oral ibuprofen with placebo; paracetamol and ibuprofen in combination Participants: 783 subjects having sustained isolated soft tissue limb injury without significant fracture presenting to the ED of Prince of Wales Hospital Main outcome measures: Pain relief profiles of paracetamol, ibuprofen and the combination of both; adverse effect profiles of paracetamol, ibuprofen and the combination of both; overall cost effectiveness of paracetamol, ibuprofen and the combination of both from the perspective of the healthcare provider
