What are the costs of managing neck and low back pain in Brazil? Investigation of a ten-year period from the perspective of the Brazilian public health system.

Introduction: Considering the prospects of increased prevalence and disability due to neck and low back pain, it is relevant to investigate the care processes adopted, to assist future public policies and decision-making for a better allocation of resources. Objective: the aim of this study was to estimate the costs arising from inpatient and outpatient care of individuals with Neck Pain (NP) and Low Back Pain (LBP) in Brazil, between 2010 and 2019. Methods: This is a cost-of-illness study from the perspective of the Brazilian public health system, based on health conditions with high prevalence (neck and low back pain). Data were presented descriptively using absolute and relative values. Results: Between 2010 and 2019, the health system spent more than $600 million (R$ 2.3 billion) to treat NP and LBP in adults, and LBP accounted for most of the expenses. Female had higher absolute expenses in inpatient care and in the outpatient system. Conclusion: Our study showed that the costs with NP and LBP in Brazil were considerable. Female patients had higher outpatient costs and male patients had higher hospitalization costs. Healthcare expenses were concentrated for individuals between 34 and 63 years of age. Plain Language Summary: This study focused on understanding how much it cost to treat neck pain (NP) and low back pain (LBP) in Brazil between 2010 and 2019, from the point of view of the public health system (i.e. Unified Health System – SUS). The idea was to find out how much money was spent and where. It turned out that the SUS spent, in total, more than US$600 million (R$2.3 billion) with LBP responsible for most of these expenses. Furthermore, we noted that women had higher outpatient care costs, while men had higher hospitalization costs. Those costs were more concentrated in people aged between 34 and 63 years.
