Although screening is effective in reducing incidence, mortality, and costs of treating colorectal cancer (CRC), it remains underutilized, in part due to limited insurance access. We used microsimulation to estimate the health and financial effects of insurance expansion and reduction scenarios in North Carolina (NC). We simulated the full lifetime of a simulated population of 3,298,265 residents age-eligible for CRC screening (ages 50-75) during a 5-year period starting January 1, 2018, including polyp incidence and progression and CRC screening, diagnosis, treatment, and mortality. Insurance scenarios included: status quo, which in NC includes access to the Health Insurance Exchange (HIE) under the Affordable Care Act (ACA); no ACA; NC

Purpose Previous analyses have found that insurance status is a strong predictor of survival among patients with colorectal cancer aged 18 to 64 years. We investigated whether differences in comorbidity level may account in part for the association between insurance status and survival. Methods We used 2003 to 2005 data from the National Cancer Data Base, a national hospital-based cancer registry, to examine the relationship between baseline characteristics and overall survival at 1 year among 64,304 white and black patients with colorectal cancer. In race-specific analyses, we used Cox proportional hazards models to assess 1-year survival by insurance status, controlling first for age, stage, facility type, and neighborhood education level and income, and then further controlling for comorbidity level. Results Comorbidity level was lowest among those with private insurance, higher for those who were uninsured or insured by Medicaid, and highest for those insured by Medicare. Surviv...
The Impact of Massachusetts Health Reform on Colorectal and Breast Cancer Stage at Diagnosis
Medical Care, 2020
Background: This study examines the expansion of health insurance coverage in Massachusetts under state health reform as a natural experiment to investigate whether expanded insurance coverage reduced the likelihood of advanced stage colorectal cancer (CRC) and breast cancer (BCA) diagnosis. Methods: Our study populations include CRC or BCA patients ages 50-64 observed in the Massachusetts Cancer Registry and Surveillance Epidemiology and End Results (SEER) registries *
Colon cancer treatment costs for Medicare and dually eligible beneficiaries
Health care financing review, 2010
To estimate the cost attributable to colon cancer treatment 1 year after diagnosis by cancer stage, comorbidity, treatment regimen, and Medicaid eligibility, we extracted an inception cohort of colon cancer patients aged 66 and older diagnosed between 1997 and 2000 from the Michigan Tumor Registry. Patients were matched to non-cancer control subjects in the Medicare Denominator file. We used the difference-in-differences method to estimate costs attributable to cancer, controlling for costs prior to diagnosis. The mean total colon cancer cost per Medicare patient was $29,196. The method can be applied to longitudinal data to estimate long term costs of cancer from inception where incident patients are identified from a tumor registry.

Recent health care reform debates have triggered substantial discussion on how best to improve access to insurance. Colorectal cancer (CRC) is an example of a largely preventable condition, if access to and use of healthcare is increased. Early and ongoing screening and intervention can identify and remove polyps before they become cancerous. We present the development of an individual-based discrete-event simulation model to estimate the impact of insurance expansion scenarios on CRC screening, incidence, mortality, and costs. A national repeated cross-sectional survey was used to estimate which individuals obtained insurance in North Carolina (NC) after the Affordable Care Act (ACA). The potential impact of expanding the state’s Medicaid program is tested and compared to no insurance reform and the ACA without Medicaid expansion. The model integrates a census-based synthetic population, national data, claims based statistical models, and a natural history module in which simulated...

Precision public health requires research that supports innovative systems and health delivery approaches, programs, and policies that are part of this vision. This study estimated the effects of health insurance mandate (HiM) variations and the effects of physician utilization on moderating colorectal cancer (CRC) screening rates. A time-series analysis using a difference-in-difference-in-differences (DDD) approach was conducted on CRC screenings (1997-2014) using a multivariate logistic framework. Key variables of interest were HiM, CRC screening status, and physician utilization. The adjusted average marginal effects from the DDD model indicate that physician utilization increased the probability of being "up-to-date" vs. non-compliance by 9.9% points (p = 0.007), suggesting that an estimated 8.85 million additional age-eligible persons would receive a CRC screening with HiM and routine physician visits. Routine physician visits and mandates that lower out-of-pocket exp...
Quality of colon cancer outcomes in hospitals with a high percentage of Medicaid patients
2008
BACKGROUND: There is evidence that patients with Medicaid insurance suffer worse outcomes from surgical conditions; but there is little research about whether this reflects clustering of such patients at hospitals with worse outcomes. We assess the outcomes of patients with colon and rectal cancers at hospitals with a high proportion of Medicaid patients. STUDY DESIGN: California Cancer Registry patient-level records were linked to discharge abstracts from California's Office of Statewide Health Planning and Development. All operative California Cancer Registry patients from 1998 and 1999 were included. Hospitals with Ͼ 40% Medicaid patients were labeled high Medicaid hospitals (HMH). We analyzed the odds of mortality at 30 days, 1, and 5 years for colon cancer and rectal cancer separately. Multilevel logistic regression models were constructed, using MLwiN 2.0, to include patient and hospital-level characteristics.

The purpose of the present paper was to examine patterns of surgical care and the likelihood of death within 5 years after a diagnosis of colorectal cancer, including the effects of demographic, locational and socioeconomic disadvantage and the possession of private health insurance. Methods: The Western Australian Data Linkage System was used to extract all hospital morbidity, cancer and death records for people with a diagnosis of colorectal cancer from 1982 to 2001. Demographic, hospital and private health insurance information was available for all years and measures of socioeconomic and locational disadvantage from 1991. A logistic regression model estimated the probability of receiving colorectal surgery. A Cox regression model estimated the likelihood of death from any cause within 5 years of diagnosis. Results: People were more likely to undergo colorectal surgery if they were younger, had less comorbidity and were married/ defacto or divorced. People with a first admission to a private hospital (odds ratio (OR) 1.31, 95% confidence interval (CI): 1.16-1.48) or with private health insurance (OR 1.27, 95% CI: 1.14-1.42) were more likely to undergo surgery. Living in a rural or remote area made little difference, but a first admission to a rural hospital reduced the likelihood of surgery (OR 0.76, 95% CI: 0.66-0.87). Residency in lower socioeconomic areas also made no difference to the likelihood of having surgical treatment. The likelihood of death from any cause was lower in those who were younger, had less comorbidity, were elective admissions and underwent surgery. Residency in lower socioeconomic status and rural areas, admission to a rural hospital or a private hospital and possession of private health insurance had no effect on the likelihood of death.
Cancer preventive services, socioeconomic status, and the Affordable Care Act
Cancer, 2017
Out-of-pocket expenditures are thought to be an important barrier to the receipt of cancer preventive services, especially for those of a lower socioeconomic status (SES). The Affordable Care Act (ACA) eliminated out-of-pocket expenditures for recommended services, including mammography and colonoscopy. The objective of this study was to determine changes in the uptake of mammography and colonoscopy among fee-for-service Medicare beneficiaries before and after ACA implementation. Using Medicare claims data, this study identified women who were 70 years old or older and had not undergone mammography in the previous 2 years and men and women who were 70 years old or older, were at increased risk for colorectal cancer, and had not undergone colonoscopy in the past 5 years. The receipt of procedures in the 2-year period before the ACA's implementation (2009-2010) and after its implementation (2011 to September 2012) was also identified. Multivariate generalized estimating equation m...
