Racial/ethnic disparities in colorectal cancer treatment utilization and phase-specific costs, 2000-2014.

ABSTRACT: BACKGROUND:Our study analyzed disparities in utilization and phase-specific costs of care among older colorectal cancer patients in the United States. We also estimated the phase-specific costs by cancer type, stage at diagnosis, and treatment modality. METHODS:We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify patients aged 66 or older diagnosed with colon or rectal cancer between 2000-2013, with follow-up to death or December 31, 2014. We divided the patient's experience into separate phases of care: staging or surgery, initial, continuing, and terminal. We calculated total, cancer-attributable, and patient-liability costs. We fit logistic regression models to determine predictors of treatment receipt and fit linear regression models to determine relative costs. All costs are reported in 2019 US dollars. RESULTS:Our cohort included 90,023 colon cancer patients and 25,581 rectal cancer patients. After controlling for patient and clinical characteristics, Non-Hispanic Blacks were less likely to receive treatment but were more likely to have higher cancer-attributable costs within different phases of care. Overall, in both the colon and rectal cancer cohorts, mean monthly cost estimates were highest in the terminal phase, next highest in the staging phase, decreased in the initial phase, and were lowest in the continuing phase. CONCLUSIONS:Racial/ethnic disparities in treatment utilization and costs persist among colorectal cancer patients. Additionally, colorectal cancer costs are substantial and vary widely among stages and treatment modalities. This study provides information regarding cost and treatment disparities that can be used to guide clinical interventions and future resource allocation to reduce colorectal cancer burden.

Project description:BackgroundAlthough Asian Americans are at high risk for type 2 diabetes, it is not known whether they are appropriately screened for this disease.ObjectiveTo assess racial and ethnic disparities in diabetes screening between Asian Americans and other adults.DesignAnalysis of pooled cross-sectional data from 45 U.S. states and territories using the 2012-2014 Behavioral Risk Factor Surveillance System. We calculated the weighted proportions of adults in each racial and ethnic group who received recommended diabetes screening. To assess for racial and ethnic disparities, we used multivariable logistic regression to model receipt of recommended diabetes screening as a function of race and ethnicity, adjusting for demographics, healthcare access, survey year, and state.ParticipantsA total of 526,000 adults who were eligible to receive diabetes screening according to American Diabetes Association guidelines from 2012 to 2014 (age ≥ 45 years or age < 45 years with a body mass index [BMI] ≥ 25 kg/m2).Main measuresSelf-reported receipt of diabetes screening (defined as a test for high blood sugar or diabetes within the past 3 years) and self-reported race/ethnicity (non-Hispanic white, non-Hispanic Asian, non-Hispanic Pacific Islander, non-Hispanic American Indian or Alaskan Native, non-Hispanic black, Hispanic or Latino, and non-Hispanic multiracial or other).Key resultsAsian Americans were the least likely racial and ethnic group to receive recommended diabetes screening. Overall, Asian Americans had 34% lower adjusted odds of receiving recommended diabetes screening compared to non-Hispanic whites (95 % CI: 0.60, 0.73). In subgroup analyses by age and weight status, disparities were widest among obese Asian Americans ≥ 45 years (AOR = 0.56; 95 % CI: 0.39, 0.81). Disparities persisted among Asian Americans who completed other types of preventive cancer screening.ConclusionsDespite their high risk of diabetes, Asian Americans were the least likely racial and ethnic group to receive recommended diabetes screening.

Project description:Background:Interval colorectal cancer (CRC) accounts for 3% to 8% of all cases of CRC in the United States. Data on interval CRC by race/ethnicity are scant. Objective:To examine whether risk for interval CRC among Medicare patients differs by race/ethnicity and whether this potential variation is accounted for by differences in the quality of colonoscopy, as measured by physicians' polyp detection rate (PDR). Design:Population-based cohort study. Setting:Medicare program. Participants:Patients aged 66 to 75 years who received colonoscopy between 2002 and 2011 and were followed through 2013. Measurements:Kaplan-Meier curves and adjusted Cox models were used to estimate cumulative probabilities and hazard ratios (HRs) of interval CRC, defined as a CRC diagnosis 6 to 59 months after colonoscopy. Results:There were 2735 cases of interval CRC identified over 235 146 person-years of follow-up. A higher proportion of black persons (52.8%) than white persons (46.2%) received colonoscopy from physicians with a lower PDR. This rate was significantly associated with interval CRC risk. The probability of interval CRC by the end of follow-up was 7.1% in black persons and 5.8% in white persons. Compared with white persons, black persons had significantly higher risk for interval CRC (HR, 1.31 [95% CI, 1.13 to 1.51]); the disparity was more pronounced for cancer of the rectum (HR, 1.70 [CI, 1.25 to 2.31]) and distal colon (HR, 1.45 [CI, 1.00 to 2.11]) than for cancer of the proximal colon (HR, 1.17 [CI, 0.96 to 1.42]). Adjustment for PDR did not alter HRs by race/ethnicity, but differences between black persons and white persons were greater among physicians with higher PDRs. Limitation:Colonoscopy and polypectomy were identified by using billing codes. Conclusion:Among elderly Medicare enrollees, the risk for interval CRC was higher in black persons than in white persons; the difference was more pronounced for cancer of the distal colon and rectum and for physicians with higher PDRs.
