Racial/ethnic disparities in patient experiences with care and Gleason score at diagnosis of prostate cancer: a SEER-CAHPS study.

To determine whether racial/ethnic differences in patient experiences with care, potentially leading to underutilization of necessary care, are associated with disparities in Gleason score at diagnosis.

We used the SEER-CAHPS linked dataset to identify Medicare beneficiaries who completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey prior to diagnosis of prostate cancer. Independent variables included aspects of patient experiences with care captured by CAHPS surveys. We conducted survey weighted multivariable multinomial logistic regression analyses, stratified by patient race/ethnicity, to estimate associations of CAHPS measures with Gleason score at diagnosis.

Of the 4,245 patients with prostate cancer, most were non-Hispanic white (NHW) (77.6%), followed by non-Hispanic black (NHB) (8.4%), Hispanic (8.4%), and Asian (5.6%). Excellent experience with getting needed prescription drugs was associated with lower odds of Gleason scores of 7 and 8-10 in NHBs (7: OR = 0.19, 95% CI = 0.05-0.67; 8-10: OR = 0.04, 95% CI = 0.01-0.2) and lower odds of 8-10 in NHWs (OR = 0.61, 95% CI = 0.40-0.93). For NHBs, excellent primary physician ratings were associated with greater odds of a Gleason score of 8-10 (OR = 13.28, 95% CI = 1.53-115.21).

Patient experiences with access to care and physician relationships may influence Gleason score in different ways for patients of different racial/ethnic groups. More research, including large observational studies with greater proportions of racial/ethnic minority patients, is necessary to understand these relationships and target interventions to overcome disparities and improve patient outcomes.
