Racial Disparities in Sacral Neuromodulation for Idiopathic Fecal Incontinence

Sacral neuromodulation (SNM) is an effective treatment for fecal incontinence (FI). Previous studies found that Black women undergo SNM for urinary incontinence less than White women, but there is less known about racial disparities for FI.

This study assessed differences in Black and White patients' FI treatment; SNM counseling was the primary outcome.

This was a retrospective cohort study of adult non-Hispanic Black and White patients who received FI treatment at an academic institution from 2011 to 2021. Medical records were queried for treatments, testing, and treating specialties for a 2:1 age-matched cohort of White:Black patients.

Four hundred forty-seven women were included: 149 Black women and 298 age-matched White women. A total of 24.4% (109) of patients had documented SNM counseling, significantly fewer in Black patients (14.8% vs 29.2%, P < 0.001). A total of 5.1% (23) of patients received SNM, less frequent in Black patients (2.7% vs 6.4%, P = 0.003). Among patients with SNM counseling, there was no difference between cohorts. Black patients were less likely to be referred for physical therapy (59.7% vs 77.2%, P < 0.001), sphincter imaging (0.7% vs 5.7%, P = 0.011), and defecography (8.1% vs 17.1%, P = 0.009). Different specialties managed the 2 cohorts. Black patients were less likely to see urogynecology and colorectal surgery (21.5% vs 34.6%, P = 0.004; 9.4% vs 15.4%, P = 0.077). Patients seen by these surgeons were more likely to discuss SNM (48.6% vs 8.5%, P < 0.001).

There were differences between Black and White patients' FI treatment, including counseling about SNM. Multidisciplinary work is needed to provide equitable education for this life-altering condition.
