Background:
Prostate cancer screening guidelines recommend shared decision-making (SDM) regarding prostate-specific antigen (PSA) testing. However, it is unclear who undergoes SDM and whether any disparities exist.
Objective:
To examine sociodemographic differences in participation of SDM and its association with PSA testing in prostate cancer screening.
Design, Setting, And Participants:
A retrospective cross-sectional study was conducted among men aged 45-75 yr undergoing PSA screening, using the 2018 National Health Interview Survey database. The evaluated sociodemographic features included age, race, marital status, sexual orientation, smoking status, working status, financial difficulty, US geographic regions, and cancer history. Questions regarding self-reported PSA testing and whether respondents discussed its advantages and disadvantages with their healthcare provider were analyzed.
Outcome Measurements And Statistical Analysis:
Our primary outcome was to evaluate the possible associations between various sociodemographic factors and undergoing PSA screening and SDM. We used multivariable logistic regression analyses to detect potential associations.
Results And Limitations:
A total of 59596 men were identified, of whom 5605 answered the question regarding PSA testing, with 2288 (40.6%) undergoing PSA testing. Of these men, 39.5% (n = 2226) discussed the advantages and 25.6% (n = 1434) discussed the disadvantages of PSA testing. On a multivariable analysis, older (odds ratio [OR] 1.092; 95% confidence interval [CI] 1.081-1.103, p < 0.001) and married (OR 1.488; 95% CI 1.287-1.720, p < 0.001) men were more likely to undergo PSA testing. Although Black men were more likely to discuss PSA advantages (OR 1.421; 95% CI 1.150-1.756, p = 0.001) and disadvantages (OR 1.554; 95% CI 1.240-1.947, p < 0.001) than White men, this did not correlate with higher rates of PSA screening (OR 1.086; 95% CI 0.865-1.364, p = 0.477). The lack of important clinical data remains a limitation.
Conclusions:
Overall, SDM rates were low. Older and married men had an increased likelihood of SDM and PSA testing. Despite higher rates of SDM, Black men had similar rates of PSA testing to White men.
Patient Summary:
We evaluated sociodemographic differences in shared decision-making (SDM) in prostate cancer screening using a large national database. We found that SDM had varying results in different sociodemographic groups.
