Title: Health Services Research Poster I

Session Type: ACR Poster Session A

Session Time: 9:00AM-11:00AM

Background/Purpose: Back pain is a very prevalent complaint affecting two-thirds of population, and accounts for 90.7 billion dollars annually in healthcare expenditure. The occurrence of depression is reported in existing literature among patients with back pain, but there is limited information regarding healthcare expenditures among patients with back pain and concurrent depression. To assess excess total and subtypes of healthcare expenditures among adults with spondylosis, intervertebral disc disorders and other back problems who reported having depression compared to those without depression in the United States (US).

Methods: We utilized a cross-sectional design pooling MEPS data from 2010-2012. The eligible study sample comprised of adults (age ≥ 18 years), who were alive during the calendar year and reported positive healthcare expenditure. Total and subtypes of healthcare expenditures constituted the dependent variable. Ordinary least square (OLS) regressions on logged expenditures were performed. Three models were developed to assess the influence of demographics, functional ability, and concurrent diagnoses on healthcare expenditures. All expenditure data are presented in terms of 2012 US dollars.

Results: A total of 6,559 adults with spondylosis, intervertebral disc disorders, and other back problems were assessed, 20.2% of which had concurrent depression. Adults with concurrent depression had significantly higher healthcare expenditures ($13,153) compared to the non-depression group ($7,477), p<0.001. Inpatient, outpatient, prescription, and home health agency expenditures showed similar findings. There was no difference in emergency room and other expenditures between the two groups. The excess total expenditure was higher (119%) among depression group when adjusted for demographic characteristics. After adjusting for healthcare and functional disabilities, and comorbidities excess cost remained higher in depression group (53%).

Conclusion: This study demonstrates that presence of depression in the adults with spondylosis, intervertebral disc disorders, and other back problems significantly influence the economic burden. These findings remained consistent despite adjusting for all independent level variables (demographic characteristics, functional status, comorbidities). The study findings suggest that interventions resulting in better control of depression have the potential to significantly reduce the economic burden in this population.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
