Determinants of clinically important pain severity reduction in the prehospital setting

This retrospective, electronic patient care record review examined a consecutive sample of patients presenting with pain to the metropolitan region of Ambulance Victoria over a 12 month period in 2008. Seven factors were found to be associated with the likelihood of clinically important pain reduction following multivariate analyses. These included age, time criticality of the patient, pain aetiology, initial pain severity, analgesic agent or combination administered to the patient and prehospital time.
