Background The Veterans’ Health Administration (VHA), currently mandates that every spinal cord injury and disorder (SCI/D) patient receives a screening urinalysis and urine culture (UC) during the annual evaluation (AE). Our pilot study at a single VHA center showed that 87% of the UCs obtained during the AE represented asymptomatic bacteriuria (ASB), and that 35% of those UC were treated with antibiotics unnecessarily. The objective of the current study is to determine the association between UC and antibiotic use using a national VHA sample of SCI/D patients. Methods Retrospective cohort of Veterans who presented to a VHA SCI/D clinic for their AE in FY18 or FY19. Demographic and clinical characteristics as well as information on primary outcomes (receipt of urine culture and antibiotics) were extracted from the VHA Corporate Data Warehouse. Associations between covariates and outcomes were assessed using logistic regression. P values &amp;lt; 0.05 were considered significant. Results 9447 veterans with SCI/D were included, of whom 5088 (54%) had a UC obtained. Of those with a UC, 2910 (57%) were classified as positive (Figure 1). 1054 (11%) veterans were prescribed antibiotics within 7 days of their AE. Of these, 515 had a positive UC, 202 had a negative UC, and 2878 did not have a UC obtained during the AE. Age, ethnicity, neurologic level of injury (NLI), comorbidity score, frequently identified organism on positive culture, and receipt of antibiotics within 7 days of AE were significantly associated with obtaining a UC during the AE. Race, NLI, bladder management strategy, comorbidity score, frequently identified organism on positive culture, and having a UC obtained during the AE were significantly associated with receipt of antibiotics within 7 days of AE. Flowchart of SCI/D Veterans who had a urine culture and/or received antibiotics during their FY18/19 AE Conclusion Over half of Veterans with SCI/D presenting for their AE receive a screening UC, contrary to other national guidelines recommending against this practice. Age and type or organism identified on UC drive antibiotic use, which was similar to our previous findings and reflect themes identified during our qualitative interviews with SCI/D providers. The knowledge gained from this national VA study will assist the development of interventions to reduce unnecessary urine testing and antibiotic use in the SCI/D population.
