e19077 Background: More than 10 million Americans identify themselves as lesbian, gay, bisexual, and transgender (LGBT), and the majority of male-to-female (MTF) transgender individuals still have prostates even after surgical transitions. Guidelines on prostate specific antigen (PSA) screening for LGBT populations are limited, and informed and shared decision making are encouraged by various organizations. However, patterns of care for PSA screening in LGBT populations remains unclear. To address this knowledge gap, we conducted a cross sectional study to evaluate self-reported PSA screening and decision making among LGBT populations. Methods: The Behavioral Risk Factor Surveillance System database was queried for LGBT adults from 2014-2016 and 2018. Those with prior prostate cancer were excluded. Multivariable logistic regression was performed to evaluate the association of LGBT status with PSA screening, informed and shared decision making, after adjusting for demographic characteristics and survey weights. Results: A total of 164,370 participants were eligible for PSA screening (n = 156,548 for cisgender [CG]+straight, n = 156 for MTF+straight, n = 33 for MTF+gay, n = 52 for MTF+bisexual, n = 51 for MTF+other sexual orientation [SO], n = 3354 for CG+gay, n = 1641 for CG+bisexual, n = 2535 for CG+other SO), representing a weighted estimate of 1.2 million LGBT populations. When compared to CG+straight, CG+gay/bisexual cohorts were more likely to undergo PSA screening within the past 2 years (CG+gay: OR 1.08, p < 0.001; CG+bisexual: OR 1.06, p < 0.001), have ever received PSA screening (CG+gay: OR 1.30, p < 0.001; CG+bisexual: OR 1.12, p < 0.001), and be recommended for PSA screening by their physicians (CG+gay and bisexual: OR 1.16, p < 0.001). All other cohorts were less likely to do so (all OR < 1, p < 0.05). MTF+gay and CG+gay participants were more likely to make informed decision (MTF+gay: OR 3.13, p < 0.001; CG+gay: OR 1.09, p < 0.001), while all other cohorts were less likely to do so (all OR < 1, p < 0.05). CG+gay participants were also more likely to share decision (OR 2.51, p < 0.001), while there were no associations for all other cohorts (all p > 0.05). Conclusions: Select gay populations were more likely to undertake PSA screening recommended by their physicians and participate in informed and shared decision making. However, other LGBT populations were less likely to make informed decisions, and transgender participants were less likely to undergo PSA screening. Further research efforts are needed to improve informed and shared decision making for PSA screening in such underserved population.
Does shared decision making increase prostate screening uptake in countries with a low prevalence of prostate cancer?
