Quality of care received and patient‐reported regret in prostate cancer: Analysis of a population‐based prospective cohort

BACKGROUND Meeting quality of care standards in oncology is recognized as important by physicians, professional organizations, and payers. Data from a population‐based cohort of patients with prostate cancer were used to examine whether receipt of care was consistent with published consensus metrics and whether receiving high‐quality care was associated with less patient‐reported treatment decisional regret. METHODS Patients with incident prostate cancer were enrolled in collaboration with the North Carolina Central Cancer Registry, with an oversampling of minority patients. Medical record ion was used to determine whether participants received high‐quality care based on 5 standards: 1) discussion of all treatment options; 2) complete workup (prostate‐specific antigen, Gleason grade, and clinical stage); 3) low‐risk participants did not undergo a bone scan; 4) high‐risk participants treated with radiotherapy (RT) received androgen deprivation therapy; and 5) participants treated with RT received conformal or intensity‐modulated RT. Treatment decisional regret was assessed using a validated instrument. RESULTS A total of 804 participants were analyzed. Overall, 66% of African American and 73% of white participants received care that met all standards (P = .03); this racial difference was confirmed by multivariable analysis. Care that included “discussion of all treatment options” was found to be associated with less patient‐reported regret on univariable analysis (P = .03) and multivariable analysis (odds ratio, 0.59; 95% confidence interval, 0.37‐0.95). CONCLUSIONS The majority of participants received high‐quality care, but racial disparity existed. Participants who discussed all treatment options appeared to have less treatment decisional regret. To the authors' knowledge, this is the first study to demonstrate an association between a quality of care metric and patient‐reported outcome. Cancer 2017;138–143. © 2016 American Cancer Society. There is a move toward quality indicators in prostate cancer, but to the authors' knowledge little is known regarding how quality care affects patient outcomes. The authors believe this study is the first to demonstrate an association between quality indicators and patient‐reported outcomes.
