Healthcare costs due to low back pain in the emergency department and inpatient setting in Sydney, Australia

Abstract

Summary Background Low back pain is the leading cause of disability worldwide and a common presentation to emergency departments, often resulting in subsequent admissions to hospital. There have been several studies investigating the cost of low back pain to society, but few specific to the emergency department and inpatient setting, especially in Australia. The aim was to describe the cost of low back pain in Australian public hospital emergency departments, and inpatient settings, and explore healthcare costs associated with different care pathways. Methods In this retrospective observational study, we explored the costs associated with an episode of care for low back pain in adults that attended three emergency departments in Sydney between 1 July 2014 and 30 June 2019. Systematised Nomenclature of Medicine—Clinical Terms (SNOMED) diagnosis codes were used to identify episodes of care where the patients had been diagnosed with non-specific low back pain or lumbosacral radicular syndromes. Serious spinal pathologies were excluded. We determined the costs for different treatment pathways involving the ambulance service, emergency department and inpatient ward care. Hospital costs were adjusted for inflation to 2019 Australian dollars (AUD). Findings There were 12,399 non-serious low back pain episodes of care during the study period. 4006 (32%) arrived by ambulance and 2067 (17%) were admitted for inpatient care. The total costs of inpatient and emergency department care across the 5-year period were AUD$36.7 million, with a mean of AUD$2959 per episode of care. The mean cost for a patient who had a non-ambulance presentation to the emergency department and was discharged was AUD$584. Patients presenting to the emergency department via ambulance and were discharged had a mean cost of AUD$1022. Patients who presented without the need of an ambulance and were admitted had a mean cost of $13,137. The most expensive care pathway was for patients arriving by ambulance with subsequent admission, with a mean cost of AUD$14,949. Interpretation The common practice of admitting patients with non-serious low back pain for inpatient care comes at great cost to the healthcare system. In a resource constrained environment, our data highlights the economic need to implement innovative, evidence-based strategies to reduce the inpatient management of these patients. Funding Nil.

Many people admitted to hospital with a provisional diagnosis of nonserious back pain are subsequently found to have serious pathology as the underlying cause

“…A total of 1129/1982 (57%) of admissions were identified as nonserious back pain, likely suitable for virtual care. These patients had a mean age of 70 [51-82], 41% were female, with 73.4% living in areas with a higher average socioeconomic index (6)(7)(8)(9)(10). Postcode data were missing for 30 admissions.…”

“…Two recent Australian studies reported that 18 [4] and 53% [5] were admitted as inpatients. The first study estimated that the cost of each admission was ~ AUD$15,000 [6].…”

“…Esto es importante ya que con un tema tan consultado y frecuente como lo es la lumbalgia se nota como los gastos aumentan cada vez más utilizando recursos que no son requeridos para su manejo ni evolución (14). Los gastos aumentan aún más cuando son trasladados en ambulancias o admitidos al hospital sin requerirlo (18).…”

Driving-induced lower back pain: Investigation of causes and recommendations with TRIZ

“…1 In Australia, the healthcare cost for LBP varies if the patient is admitted to the hospital (AUD$ 14,949) or discharged from an emergency department (AUD$ 584). 2 In addition, LBP also radically changes one's life and identity over time. 3,4 Driving-induced lower back pain (DLBP) While there are findings on the risk factors for DLBP, there is limited evidence supporting that whole-body vibrations directly increase DLBP risks.…”
