Adults With Spina Bifida Fare Worse Than Young Adults: A Systemic Vulnerability in Urinary Tract Infection-Related Hospital Care.

Abstract

Purpose: We aim to estimate the odds of UTI-related hospital care in spina bifida (SB) patients aged 18 to 25 years as compared with patients with SB in adolescence (11-17 years) or adulthood (26-35 years). We hypothesize that patients with SB in the typical transitional age, 18 to 25 years, will have higher odds of UTI-related hospital care as compared to adolescent SB patients or adult SB patients.

Materials and methods: Using Cerner Real-World Data, we performed a retrospective cohort analysis comparing SB patients to age- and gender-matched controls. SB cases between 2015 and 2021 were identified and compared in 3 cohorts: 11 to 17 years (adolescents), 18 to 25 years (young adults [YA]), and 26 to 35 years (adults). Logistic regression analysis was used to characterize the odds of health care utilization.

Results: Of the 5497 patients with SB and 77,466 controls identified, 1839 SB patients (34%) and 3275 controls (4.2%) had at least 1 UTI encounter. UTI-related encounters as a proportion of all encounters significantly increased with age in SB patients (adolescents 8%, YA 12%, adult 15%; P < .0001). Adjusting for race, sex, insurance, and comorbidities, the odds of a UTI-related encounter in YA with SB were significantly higher than for adolescents with SB (adolescent odds ratio = 0.65, 95% CI: 0.57-0.75, P < .001). YA had lower odds of a UTI-related encounter as compared with adults with SB (adult odds ratio = 1.31, 95% CI: 1.16-1.49, P < .001).

Conclusions: YA with SB have higher odds of UTI-related hospital care than adolescents, but lower odds of UTI-related hospital care when compared with adults.
