Racial/Ethnic Disparities in Patient Experiences With Health Care in Association With Earlier Stage at Colorectal Cancer Diagnosis: Findings From the SEER-CAHPS Data.

Background Racial/ethnic minorities are more likely to be diagnosed at a later stage of colorectal cancer (CRC). Therefore, our objective was to identify whether racial/ethnic differences in patient experiences (PE) with health care are associated with stage at CRC diagnosis. Methods The authors used the National Cancer Institute Surveillance, Epidemiology and End Results registry data linked with the Consumer Assessment of Healthcare Providers and Systems to conduct a retrospective cohort analysis. They examined composite measures from surveys to assess 3 domains: patient-centeredness, timeliness, and realized access. Multivariable logistic regression was used to determine the association between PE with care and earlier stage at diagnosis. Results Of the 9211 patients, 31.1% non-Hispanic White, 27.2% non-Hispanic Black (NHB), 32.3% Hispanic, and 36.4% Asian were diagnosed with early stage cancer. Compared with non-Hispanic White patients, for the timeliness domain, Hispanic [β=-2.82; 95% confidence interval (CI), -5.42 to -0.39] and Asian (β=-6.65; 95% CI, -9.44 to -3.87) patients had significant lower adjusted mean score for getting care quickly. For the realized access domain, Asian (β=-5.78; 95% CI, -8.51 to -3.05) and NHB patients (β=-3.18; 95% CI, -5.50 to -0.87) had significantly lower adjusted mean score for getting needed prescription drugs compared with non-Hispanic White patients. Among NHB patients, a 5-Unit increase in getting needed care quickly was associated with higher odds of earlier CRC stage at diagnosis (odds ratio, 1.06; 95% CI, 1.01-1.10). Conclusion There are racial/ethnic disparities in PE with timeliness and realized access to care preceding a CRC diagnosis. Among NHB patients, poor experiences with timeliness and realized access of care may be associated with later stage at diagnosis.
