Negative perceptions of the health system and racial inequities in PSA screening

Abstract

Background

Black individuals in the U.S. experience significantly higher prostate cancer mortality and are more likely to be diagnosed at younger ages with aggressive disease. This disparity may be influenced by negative healthcare perceptions and racial discordance between patients and providers, impacting lower rates of prostate-specific antigen (PSA) screening. We hypothesized that these factors would be associated with reduced PSA screening uptake, particularly among Black men.

Objectives

This study aimed to examine the association between negative healthcare perceptions and PSA screening, assess whether this relationship differs by race, and evaluate the role of racial discordance in influencing screening behavior.

Methods

We analyzed data from the 2018–2022 Medical Expenditure Panel Survey. The sample included 2373 men aged 45–70 who self-identified as non-Hispanic White or Black and had complete data on PSA screening, healthcare perceptions, and demographics. Negative healthcare perceptions were measured using a Health Perceptions Index (HePI), constructed from MEPS items (higher scores reflect more negative perceptions).

Results

Higher HePI scores were significantly associated with lower PSA screening rates (p < 0.01). Interaction models indicated that Black men with higher HePI scores were disproportionately less likely to undergo screening. Racial discordance with providers was independently associated with reduced screening likelihood (~10.2 percentage points; p < 0.01). Models including interaction terms (age, race, and discordance) showed that older Black men with high HePI scores and discordant providers were least likely to be screened.

Conclusions

PSA screening disparities are shaped by negative healthcare perceptions and racial discordance, particularly among older Black men. Addressing these barriers through culturally tailored education, improved workforce diversity, and strengthened provider–patient relationships may help close screening gaps. These findings highlight the relevance of healthcare system perceptions in understanding screening disparities and may inform future strategies to identify at-risk individuals.
