INTRODUCTION
There are 3.3 million men living with prostate cancer in the United States (US). About 300,000 men are diagnosed annually in the US. Prior literature suggests the prevalence of prostate cancer is similar across the different racial groups. However, it remains uncertain whether healthcare utilization, such as hospitalizations, is consistent across patients of different races.
METHODS
This study compared the prevalence of hospital admission for prostate cancer for Black and White men in the final 15 years of the National Hospital Discharge Survey (1996 – 2010). Hospital cases were included if patients were at least 18 years of age and had a primary ICD9 (diagnosis code) for prostate cancer. Analysis weights were applied to obtain national estimates. The U.S National Census Bureau was used to estimate the number of Black and White men living in the U.S. during the study period. The proportion of cases divided by those at-risk was multiplied by a base of 10,000 to calculate population prevalence rates. Chi-square was used to compare prevalence rates by year, and Wilcoxon for the overall study period and age distribution for the two patient groups. P-values less than an alpha level of 0.01 were considered statistically significant.
RESULTS
The NHDS contained 1,336,454 hospital cases with a primary diagnosis of prostate cancer; 144,335 (11%) were Black men and 801,682 (60%) were White men. The median age of the population was 65 years, with 63 years for Black men and 65 years for White men (p<0.0001). Overall there were more patients with hospital admissions from the South than other regions in U.S; more specifically an increase in Black men(Black men 49.5%, White men 36.4%). The prevalence rate for the entire study period was also statistically similar for Black and White men (p=0.0698). The annual prevalence rate remained relatively stable throughout the study period, ranging from 6.9 in 1996 to 6.0 in 2010 for Black, and White men from 5.2 in 1996 to 4.9 in 2010.
CONCLUSIONS
The prevalence of NHDS hospital cases with a primary diagnosis of prostate cancer for Black and White men was nearly identical to the expected proportion of the U.S population who are Black and White, as measured by the U.S Census Bureau. Furthermore, the annual prevalence rate remained similar and relatively stable for both groups throughout the study period. Therefore, there does not appear to be a health disparity in regards to the proportions of Black and White men admitted to U.S. hospitals for prostate cancer.
