Abstract PO-249: Prostate screening & patient knowledge on PSA testing among males: Analysis of the 2019 NHIS

Abstract

Abstract Intro: Prostate cancer, one of the most common cancers for males, continues to have non-standardized screening with Prostate Specific Antigen (PSA) due to the potential risks and uncertainties that PSA screening can pose. Methods: The purpose of this study is to investigate the knowledge base of participants regarding the advantages and disadvantages of PSA screening. Using the 2019 National Health Interview Survey, we performed descriptive statistics on participant demographics and prostate screening questions. Bivariate and multivariable logistic regression was utilized to highlight variables that were associated with whether or not a doctor explained to a participant the advantages and disadvantages of PSA testing. Results: Overall, we gathered answers from 10,165 respondents aged 40 years or older, from a total of 31,997 participants in the 2019 NHIS survey. Nearly half of respondents (5004, 49.2%) reported that they had undergone a PSA test in the past and 38.6% of respondents reported that a doctor had discussed the advantages of a PSA test. On the other hand, only 25.8% reported that a doctor had discussed possible disadvantages of PSA testing. Our stratified analyses found that Asians were less likely to report that a doctor had discussed the advantages of a PSA test (OR = 0.59, P < 0.05). We also found that the higher the educational status of a participant, the more likely a participant would report that a doctor talked about the advantages of a PSA test (high school graduates, OR = 1.83, P<0.05; college degrees, OR = 2.48, P < 0.05). Those without any form of health insurance coverage were less likely to be told about the advantages of PSA testing (OR = 0.60, P< 0.05). Similar values in each of these covariates were also found to be statistically significant when participants were asked if a doctor had talked to them about the disadvantages of a PSA test. Conclusions: We found disparities of prostate cancer screening education based on social factors, which reinforce concerns of disparate access of information provided by physicians on the advantages and disadvantages of a PSA testing. Our findings support a call for the improvement of adequate patient-doctor discussions that fully address the risks and benefits of PSA testing. Citation Format: Isabela M. Bumanlag, Humberto R.
