Predictors of Colorectal Cancer Screening Modality Among Newly Age-Eligible Medicaid Enrollees

The Role of Health Information Technology on Colorectal Cancer Screening Participation Among Smokers In The United States

Background: Despite advances in its prevention and early detection, colorectal cancer (CRC) remains a leading cause of morbidity and mortality in the United States and smokers are at an increased risk. Health information technology (HIT) has shown promise in the uptake of preventive health services, including CRC, and may prove useful among smokers. Methods: We obtained data from 7,419 adults who completed the 2018-2020 Health Information National Trends Survey. Using multivariable logistic regression models, we examined the relationship between HIT use and CRC screening participation. Results: Over 20% of current smokers had no access to HIT tools, and those with access were less likely than never smokers to use HIT in checking test results (odds ratio [OR] 0.58; 95% confidence interval [CI] [0.42-0.80]). Among former smokers, using HIT to check test results (OR 3.41; 95% CI [1.86-6.25]), look up health information online (OR 2.20; 95% CI [1.15-4.22]), and make health appointments (OR 2.86; 95% CI [1.39-5.89]) was associated with increased participation in CRC screening. Among current smokers, the use of HIT was not associated with a change in CRC screening participation. Conclusion: HIT use is associated with higher levels of CRC screening among former smokers, which is reassuring given their increased risk of CRC. The low ownership and use of HIT among current smokers of CRC screening age presents a challenge that may limit the integration of HIT into routine CRC screening services.

Prevalence and predictors of colorectal cancer screening in the United States: evidence from the HINTS database 2018 to 2020

BACKGROUND

The incidence of colorectal cancer (CRC) and CRC-related mortality among young adults (< 50 years) has been on the rise. The American Cancer Society (ACS) reduced the CRC screening age to 45 in 2018. Few studies have examined the barriers to CRC screening among young adults.

METHODS

Analyses were conducted using data from 7,505 adults aged 45-75 years who completed the 2018 to 2020 Health Information National Trends Survey. We examined the sociodemographic characteristics associated with CRC screening overall and by age group using separate multivariable logistic regression models.

RESULTS

76% of eligible adults had received screening for CRC. Increasing age, Black racial group [OR 1.45; 95% CI (1.07, 1.97)], having some college experience, a college degree or higher [OR 1.69; 95% CI (1.24, 2.29)], health insurance coverage [OR 4.48; 95% CI (2.96, 6.76)], primary care provider access [OR 2.48; 95% CI (1.91, 3.22)] and presence of a comorbid illness [OR 1.39; 95% CI (1.12, 1.73)] were independent predictors of CRC screening. Current smokers were less likely to undergo CRC screening [OR 0.59; 95% CI (0.40, 0.87)]. Among adults aged 50-64 years, being of Hispanic origin [OR 0.60; 95% CI (0.39, 0.92)] was associated with a lower likelihood of CRC screening.

CONCLUSION

CRC screening rates among adults 45-49 years are low but are increasing steadily. Odds of CRC screening among Blacks is high which is encouraging while the odds among current smokers is low and concerning given their increased risk of developing CRC.

An observational study of workflows to support fecal testing for colorectal cancer screening in primary care practices serving Medicaid enrollees

Abstract

Background

Screening supports early detection and treatment of colorectal cancer (CRC). Provision of fecal immunochemical tests/fecal occult blood tests (FIT/FOBT) in primary care can increase CRC screening, particularly in populations experiencing health disparities. This study was conducted to describe clinical workflows for FIT/FOBT in Oregon primary care practices and to identify specific workflow processes that might be associated (alone or in combination) with higher (versus lower) CRC screening rates.

Methods

Primary care practices were rank ordered by CRC screening rates in Oregon Medicaid enrollees who turned age 50 years from January 2013 to June 2014 (i.e., newly age-eligible). Practices were recruited via purposive sampling based on organizational characteristics and CRC screening rates. Data collected were from surveys, observation visits, and informal interviews, and used to create practice-level CRC screening workflow reports. Data were analyzed using descriptive statistics, qualitative data analysis using an immersion-crystallization process, and a matrix analysis approach.

Results

All participating primary care practices (N=9) used visit-based workflows, and four higher performing and two lower performing used population outreach workflows to deliver FIT/FOBTs. However, higher performing practices (n=5) had more established workflows and staff to support activities. Visit-based strategies in higher performing practices included having dedicated staff identify patients due for CRC screening and training medical assistants to review FIT/FOBT instructions with patients. Population outreach strategies included having clinic staff generate lists and check them for accuracy prior to direct mailing of kits to patients. For both workflow types, higher performing clinics routinely utilized systems for patient reminders and follow-up after FIT/FOBT distribution.

Conclusions

Primary care practices with higher CRC screening rates among newly age-eligible Medicaid enrollees had more established visit-based and population outreach workflows to support identifying patients due for screening, FIT/FOBT distribution, reminders, and follow up. Key to practices with higher CRC screening was having medical assistants discuss and review FIT/FOBT screening and instructions with patients. Findings present important workflow processes for primary care practices and may facilitate the implementation of evidence-based interventions into real-world, clinical settings.

The impact of cumulative colorectal cancer screening delays: A simulation study

OBJECTIVE

Annual fecal immunochemical tests can reduce colorectal cancer incidence and mortality. However, screening is a multi-step process and most patients do not perfectly adhere to guideline-recommended screening schedules. Our objective was to compare the reduction in colorectal cancer incidence and life-years gained based on US guideline-concordant fecal immunochemical test screening to scenarios with a range of delays.

METHOD

The Colorectal Cancer Simulated Population model for Incidence and Natural history (CRC-SPIN) microsimulation model was used to estimate the effect of systematic departures from fecal immunochemical test screening guidelines on lifetime screening benefit.

RESULTS

The combined effect of consistent modest delays in screening initiation (1 year), repeated fecal immunochemical test screening (3 months), and receipt of follow-up or surveillance colonoscopy (3 months) resulted in up to 1.3 additional colorectal cancer cases per 10,000, 0.4 additional late-stage colorectal cancer cases per 10,000 and 154.7 fewer life-years gained per 10,000. A 5-year delay in screening initiation had a larger impact on screening effectiveness than consistent small delays in repeated fecal immunochemical test screening or receipt of follow-up colonoscopy after an abnormal fecal immunochemical test. The combined effect of consistent large delays in screening initiation (5 years), repeated fecal immunochemical test screening (6 months), and receipt of follow-up or surveillance colonoscopy (6 months) resulted in up to 3.7 additional colorectal cancer cases per 10,000, 1.5 additional late-stage colorectal cancer cases per 10,000 and 612.3 fewer life-years gained per 10,000.

CONCLUSIONS

Systematic delays across the screening process can result in meaningful reductions in colorectal cancer screening effectiveness, especially for longer delays. Screening delays could drive differences in colorectal cancer incidence across patient groups with differential access to screening.
