Paramedic management of non-traumatic back pain in a large Australian ambulance service: a retrospective study

Introduction: Non-traumatic back pain commonly leads people to seek health care from paramedics via triple-zero (emergency phone number in Australia), yet the management approaches by providers of ambulance services remain unclear. Study Objectives: This study aims to investigate paramedic management of non-traumatic back pain in New South Wales (NSW), Australia, including the call characteristics, provisional diagnoses, and the clinical care being delivered by paramedics. Methods: This study is a retrospective analysis of NSW Ambulance computer-aided dispatch and electronic medical records from January 1, 2017 through December 31, 2022. Adults who sought ambulance service with a chief complaint of back pain, were triaged as non-traumatic back pain, and subsequently received treatment by paramedics were included. Multivariable logistic regression models were used to explore factors associated with primary outcomes; ambulance transport, opioid use, and use of medication combinations were reported as odds ratios (ORs). Results: There were 73,128 calls to NSW Ambulance with a chief complaint of back pain that were triaged as non-traumatic back pain. Of these, 54,444 (74.4%) were diagnosed with spinal pain, of which 52,825 (97.1%) were categorized by the paramedic as back or neck pain, 1,573 (2.9%) as lumbar radicular pain, and 46 (0.1%) as serious spinal pathology. Eight out of ten patients with spinal pain were transported to emergency departments. The medicine most administered by a paramedic was an opioid (37.4% of patients with spinal pain). Older patients (OR = 1.36; 95% CI, 1.30 to 1.44) were more likely to be transported to an emergency department. Patients with moderate (OR = 4.39; 95% CI, 4.00 to 4.84) and severe pain (OR = 18.90; 95% CI, 17.18 to 20.79) were more likely to be administered an opioid. Conclusions: Paramedic management of non-traumatic back pain in NSW typically results in the administration of an opioid and transport to an emergency department.
