ABSTRACT

OBJECTIVE: To evaluate the association between ethnicity/insurance status and time to kidney stone surgery.

METHODS: We retrospectively assessed all patients with evaluation of nephrolithiasis in the emergency room (ED), followed by definitive stone surgery (ureteroscopy/percutaneous nephrolithotomy/ESWL) at our major academic health system consisting of 3 hospitals in a dense, urban center.

RESULTS: 682 patients were included. A total of 2.8% (n=19) were uninsured, 19.3% (n=132) were enrolled in Medicaid, 23.3% (n=159) were enrolled in Medicare and 54.5% (n=372) had commercial insurance. Uninsured patients had a short median time to surgery of only 21 days (IQR 6-49), while Medicare patients had a longer time at 39 days, (IQR 17-64), although these were not significantly different (p=0.12). Black race was associated with a higher percentage of uninsured and Medicaid patients (p = <.001). There was no difference in clinical or patient reported characteristics between the insurance groups (all p>0.05) 6.9%, 17.7%, 26.7%, and 48.6% of patients self-identified as Hispanic, Other, Black, and White, respectively. Hispanic patients had the shortest median time to surgery of 28 days (IQR 10-48), while Black patients the longest with a median of 38.5 days (18-72) (p=0.007). Clinical variables at presentation including nausea/vomiting, hydronephrosis and sepsis were not statistically significant between the patient groups (all p>0.05).

CONCLUSION: Our study illustrates persistent delays in surgery scheduling for Black patients regardless of insurance status. This should inform practice patterns for urology providers, highlighting our need to enact institutional safety nets to promote expedient follow up for a vulnerable population.
