Abstract

Abstract: Background: Orthopaedic sequelae such as skin and soft-tissue abscesses are frequent complications of intravenous drug use (IVDU) and comprise many of the most common indications for emergency room visits and hospitalizations within this population. Urban tertiary-care and safety-net hospitals frequently operate in challenging economic healthcare environments and are disproportionately tasked with providing care to this largely underinsured patient demographic. Although many public health initiatives have been instituted in recent years to understand the health impacts of IVDU and the spreading opioid epidemic, few efforts have been made to investigate its economic impact on healthcare systems. The inpatient treatment of orthopaedic sequelae of IVDU is a high-cost healthcare element that is critically important to understand within the current national context of inflationary healthcare costs. Questions/purposes: (1) What were the total healthcare costs incurred and total hospital reimbursements received in the treatment of extraspinal orthopaedic sequelae of IVDU? (2) What were the total healthcare costs incurred and total hospital reimbursements received in the treatment of spinal orthopaedic sequelae of IVDU? (3) How did patient insurance status effect the economic burden of orthopaedic sequelae of IVDU? Methods: An internal departmental record of all successive patients requiring inpatient treatment of orthopaedic sequelae of IVDU was initiated at Boston Medical Center (Boston, MA, USA) in 2012 and MetroHealth Medical Center (Cleveland, OH, USA) in 2015. A total of 412 patient admissions between 2012 to 2017 to these two safety-net hospitals (n = 236 and n = 176, respectively) for orthopaedic complications of IVDU were included in the study. These sequelae included cellulitis, cutaneous abscess, bursitis, myositis, tenosynovitis, septic arthritis, osteomyelitis, and epidural abscess. Patients were included if they were older than 18 years of age, presented to the emergency department for management of a musculoskeletal infection secondary to IVDU, and required inpatient orthopaedic treatment during their admission. Exclusion criteria included all patients presenting with a musculoskeletal infection not directly secondary to active IVDU. Patients presenting with an epidural abscess (Boston Medical Center, n = 36) were evaluated separately to explore potential differences in costs within this subgroup. A robust retrospective financial analysis was performed using internal financial databases at each institution which directly enumerated all true hospital costs associated with each patient admission, independent of billed hospital charges. All direct, indirect, variable, and fixed hospital costs were individually summed for each hospitalization, constituting a true "bottom-up" micro-costing approach. Labor-based costs were calculated through use of time-based costing; for instance, the cost of nursing labor care associated with a patient admission was determined through ascription of the median hospital cost of a registered nurse within that department (that is, compensation for salary plus benefits) to the total length of nursing time needed by that patient during their hospitalization. Primary reimbursements reflected the true monetary value received by the study institutions from insurers and were determined through the total adjusted payment for each inpatient admission. All professional fees were excluded. A secondary analysis was performed to assess the effect of patient insurance status on hospital costs and reimbursements for each patient admission. Results: The mean healthcare cost incurred for the treatment of extraspinal orthopaedic sequelae of IVDU was USD 9524 ± USD 1430 per patient admission. The mean hospital reimbursement provided for the treatment of these extraspinal sequelae was USD 7678 ± USD 1248 per patient admission. This resulted in a mean financial loss of USD 1846 ± USD 1342 per patient admission. The mean healthcare cost incurred at Boston Medical Center for the treatment of epidural abscesses secondary to IVDU was USD 44, 357 ± USD 7384 per patient. Hospital reimbursements within this subgroup were highly dependent upon insurance status. The median (range) reimbursement provided for patients possessing a unique hospital-based nonprofit health plan (n = 4) was USD 103, 016 (USD 9022 to USD 320, 123), corresponding to a median financial gain of USD 24, 904 (USD 2289 to USD 83, 079). However, the mean reimbursement for all other patients presenting with epidural abscesses (n = 32) was USD 30, 429 ± USD 5278, corresponding to a mean financial loss of USD 5768 ± USD 4861. A secondary analysis demonstrated that treatment of extraspinal orthopaedic sequelae of IVDU for patients possessing Medicaid insurance (n = 309) resulted in a financial loss of USD 2813 ± USD 1593 per patient admission. Conversely, treatment of extraspinal orthopaedic sequelae for patients possessing non-Medicaid insurance (n = 67) generated a mean financial gain of USD 2615 ± USD 1341 per patient admission. Conclusions: Even when excluding all professional fees, the inpatient treatment of orthopaedic sequelae of IVDU resulted in substantial financial losses driven primarily by high proportions of under- and uninsured people within this patient population. These financial losses may be unsustainable for medical centers operating in challenging economic healthcare landscapes. The development of novel initiatives and support of existing programs aimed at mitigating the health-related and economic impact of IVDU must remain a principal priority of healthcare providers and policymakers in coming years. Advocacy for the expansion of Medicaid accountable care organizations and national syringe service programs (SSPs), and the development of specialized outpatient wound and abscess clinics at healthcare centers may help to substantially alleviate the economic burden of the orthopaedic sequelae of IVDU.
