Examination of prostate-specific antigen (PSA) screening in military and civilian men: analysis of the 2018 behavioral risk factor surveillance system

Purpose To determine whether military men report different prostate-specific antigen (PSA) screening rates than civilian men and if shared decision-making (SDM) is associated with PSA screening. Methods We used data from the 2018 Behavioral Risk Factor Surveillance System and included 101,901 men (26,363 military and 75,538 civilian men) in the analysis conducted in 2021. We conducted binomial logistic regression analyses to determine covariate-adjusted associations between military status and receiving a PSA test in the last 2 years. We then added patient reports of SDM to the model. Finally, we looked at the joint effects of military status and SDM on the receipt of a PSA test in the last 2 years. Results Military men had 1.1 times the odds of PSA testing compared to civilian men (95% CI 1.1, 1.2) after adjusting for SDM and sociodemographic and health covariates. When examining the joint effect of military status and SDM, military and civilian men had over three times the odds of receiving a PSA test in the last 2 years if they had reported SDM (OR 3.5 and OR 3.4, respectively) compared to civilian men who did not experience SDM. Conclusion Military men are slightly more likely to report receiving a PSA test in the last 2 years compared to civilian men. Additionally, results show SDM plays a role in the receipt of a PSA test in both populations. These findings can serve as a foundation for tailored interventions to promote appropriate SDM for PSA screening in civilian, active duty, and veteran healthcare systems.
