This paper aims to determine whether racial disparities exist in hospitalization outcomes among African-American and White hospitalized prostate cancer patients in the United States. We evaluated racial differences among matched groups of patients in post-operative complications, hospital length of stay and in-hospital mortality.

We identified a total of 183,856 men aged 40 years and older with a primary diagnosis of prostate cancer, of which 58,701 underwent prostatectomy, through the Nationwide Inpatient Sample, and matched all African-American patients with White patients on: 1) Demographics, 2) Demographics+Clinical presentation and 3) Demographics+Clinical presentation+Treatment. Multivariable regression analyses were conducted in SAS and estimates were reported with 95% confidence intervals.
African-American patients were more likely to be admitted with metastatic disease (24.8%) compared with White patients matched on demographics (17.9%), and demographics+presentation (23.6%). However, 23.9% of African-American patients received surgery compared with 38.2% and 34.2% of Whites matched on demographics and demographics+presentation, respectively. White patients had lower in-hospital mortality compared with African-American patients matched on demographics (OR: 0.72, 95% CI: 0.66-0.79), demographics+presentation (OR: 0.88, 95% CI: 0.81-0.96), but was no longer significantly lower when matched on demographics, presentation and treatment (OR: 0.92, 95% CI: 0.85-1.00).
There were significant racial differences in outcomes among prostate cancer patients within the inpatient setting, even after accounting for demographic and presentation differences.
