Geographic and population-level disparities in colorectal cancer testing: A multilevel analysis of Medicaid and commercial claims data

Spatial Insights for Understanding Colorectal Cancer Screening in Disproportionately Affected Populations, Central Texas, 2019

INTRODUCTION

Colorectal cancer (CRC) screening can reduce morbidity and mortality; however, important disparities exist in CRC uptake. Our study examines the associations of distance to care and frequency of using primary care and screening.

METHODS

To examine the distribution of screening geographically and according to several demographic features, we used individual patient-level data, dated September 30, 2018, from a large urban safety-net health system in Central Texas. We used spatial cluster analysis and logistic regression adjusted for age, race, sex, socioeconomic status, and health insurance status.

RESULTS

We obtained screening status data for 13,079 age-eligible patients from the health system's electronic medical records. Of those eligible, 55.1% were female, and 55.9% identified as Hispanic. Mean age was 58.1 years. Patients residing more than 20 miles from one of the system's primary care clinics was associated with lower screening rates (odds ratio [OR], 0.63; 95% CI, 0.43-0.93). Patients with higher screening rates included those who had a greater number of primary care-related (nonspecialty) visits within 1 year (OR, 6.90; 95% CI, 6.04-7.88) and those who were part of the county-level medical assistance program (OR, 1.61; 95% CI, 1.40-1.84). Spatial analysis identified an area where the level of CRC screening was particularly low.

CONCLUSION

Distance to primary care and use of primary care were associated with screening. Priorities in targeted interventions should include identifying and inviting patients with limited care engagements.

Correlates of non-adherence to breast, cervical, and colorectal cancer screening among screen-eligible women: a population-based cohort study in Ontario, Canada

PURPOSE

Breast, cervical, and colorectal cancers are cancers that can be detected early through screening. Despite organized cancer screening programs in Ontario, Canada participation remains low among marginalized populations. Although extensive research has been done about factors contributing to under-screening by cancer site, the predictors of under/never screened conjointly for all three types of cancer remain unknown.

METHODS

Using provincial-level linked administrative data sets, we examined Ontario women who were screen-eligible for all three types of cancer over a 36-month period (i.e., April 2014-March 2017) and determined how many were up to date on 0, 1, 2, and all three types of screenings. Multivariate logistic regression was utilized to examine individual and structural predictors of screening with the group overdue for all screening being the reference group.

RESULTS

Of the 1,204,551 screen-eligible women, 15% were overdue for all. Living in the lowest income neighborhoods (AOR 0.46 [95% CI 0.45-0.47]), being recent immigrants (AOR 0.54 [95% CI 0.53-0.55]), having no primary care provider (AOR 0.17 [95% CI 0.16-0.17]), and having no contact with health care services (AOR 0.09 [95% CI 0.09-0.09]) significantly increased the likelihood of being overdue for all versus no screening type.

CONCLUSIONS

Considering that more than 15% of screen-eligible women in Ontario were overdue for all types of cancer screening, it is imperative to address structural barriers such as lack of a primary care provider. Innovative interventions like "one-stop shopping" where screening for different cancers can be offered at the same time could promote screening uptake.

Late-Stage Diagnosis and Cost of Colorectal Cancer Treatment in Two State Medicaid Programs

INTRODUCTION

To assess timing of Medicaid enrollment with late-stage colorectal cancer (CRC) diagnosis and estimate treatment costs by stage at diagnosis.

METHODS

We analyzed 2000-2009 California and Texas Medicaid data linked with cancer registry data. We assessed the association of Medicaid enrollment timing with late-stage colorectal cancer and estimated total and incremental 6-month treatment costs to Medicaid by stage using a noncancer comparison group matched on age group and sex.

RESULTS

Compared with Medicaid enrollment before diagnosis, enrolling after diagnosis was associated with late-stage diagnosis. Incremental per-person treatment costs were $31,063, $39,834, and $47,161 for localized, regional, and distant stage in California, respectively; and $28,701, $38,212, and $49,634 in Texas, respectively.

DISCUSSION

In California and Texas, Medicaid enrollment after CRC diagnosis was associated with later-stage disease and higher treatment costs. Facilitating timely and continuous Medicaid enrollment may lead to earlier stage at diagnosis, reduced costs, and improved outcomes.

Differences Related to Cancer Screening by Minority and Rural/Urban Status in the Deep South: Population-based Survey Results

Objective: Cancer mortality in the U.S. Deep South exceeds national levels. A cross-sectional survey was undertaken across Alabama to discern cancer beliefs and screening practices, and compare data from racial/ethnic minority versus majority and rural versus urban respondents. Methods: Using population-based methods, we approached 5,633 Alabamians (ages 50-80) to complete a 58-item survey (administered in-person, via telephone, or the web). Descriptive statistics were used to summarize findings; two-tailed, chi-square and t-tests (α<0.05) were used to compare minority-majority and rural-urban subgroups. Results: The response rate was 15.2%; respondents identified as minority (n=356) or majority (n=486), and rural (n=671) or urban (n=183). Mean (SD) age was 63.7 (10.2) and >90% indicated stable housing, and healthcare coverage and access. Rural and minority versus urban and majority respondents were significantly more likely to have lower education, employment, and income, respectively. Most respondents equated cancer as a "death sentence" and were unable to identify the age at which cancer screening should begin. Few rural-urban subgroup differences were noted, though significant differences were observed between minority versus majority subgroups for mammography (36.7% versus 49.6%, p<.001) and colorectal cancer screening (34.5% vs. 47.9%, p<0.001). Furthermore, while minorities were significantly more likely to report ever having a colonoscopy (82.1% versus 76.1%, p=0.041) and to have received fecal occult blood testing within the past year (17.2% versus 12.2%, p=0.046), routine adherence to screening was <20% across all subgroups. Discussion: Cancer early detection education is needed across Alabama to improve cancer screening, and particularly needed among racial/ethnic minorities to raise cancer awareness.

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

INTRODUCTION

This study examines individual- and practice-level predictors of screening modality among 1,484 Medicaid enrollees who initiated colorectal cancer screening (fecal immunochemical test/fecal occult blood tests or colonoscopy) within a year of turning age 50 years. Understanding screening modality patterns for patients and health systems can help optimize colorectal cancer screening initiatives that will lead to high screening completion rates.

METHODS

Multivariable logistic regression was conducted in 2019 to analyze Medicaid claims data (January 2013-June 2015) to explore predictors of colonoscopy screening (versus fecal testing).

RESULTS

Overall, 64% of enrollees received a colonoscopy and 36% received a fecal immunochemical test/fecal occult blood test. Male (OR=1.21, 95% CI=1.08, 1.37) compared with female enrollees and those with 4-6 (OR=1.57, 95% CI=1.15, 2.15), 7-10 (OR=2.23, 95% CI=1.64, 3.03), and ≥11 (OR=1.79, 95% CI=1.22, 2.65) primary care visits compared with 0-3 visits had higher odds of colonoscopy screening. Non-White, non-Hispanic enrollees (OR=0.71, 95% CI=0.58, 0.87) compared with White, non-Hispanics Whites had lower odds of colonoscopy screening. Practices with an endoscopy facility within their ZIP code (OR=1.50, 95% CI=1.08, 2.08) compared with practices without a nearby endoscopy facility had higher odds of colonoscopy screening.

CONCLUSIONS

Among newly age-eligible Medicaid enrollees who received colorectal cancer screening, non-White, non-Hispanic individuals were less likely and male enrollees and those with ≥4 primary care visits were more likely to undergo colonoscopy versus fecal immunochemical test/fecal occult blood test. Colonoscopy also was the more common modality among adults whose primary care clinic had an endoscopy facility in the same ZIP code. Future research is needed to fully understand patient, provider, and practice preferences regarding screening modality.

Colorectal Cancer Screening Uptake: Differences Between Rural and Urban Privately-Insured Population

Earlier studies investigated rural-urban colorectal cancer (CRC) screening disparities among older adults or used surveys. The objective was to compare screening uptake between rural and urban individuals 50–64 years of age using private health insurance. Data were analyzed from 58,774 Blue Cross Blue Shield of Nebraska beneficiaries. Logistic regression was used to assess the association between rural-urban and CRC screening use. Results indicate that rural individuals were 56% more likely to use the Fecal Occult Blood Test (FOBT) compared with urban residents, but rural females were 68% less likely to use FOBT. Individuals with few Primary Care Physician (PCP) visits and rural-women are the least to receive screening. To enhance CRC screening, a policy should be devised for the training and placement of female PCP in rural areas. In particular, multilevel interventions, including education, more resources, and policies to increase uptake of colorectal cancer screening, are needed. Further research is warranted to investigate barriers to CRC screening in rural areas.

Rural-urban differences in health-related quality of life: patterns for cancer survivors compared to other older adults

PURPOSE

Health-related quality of life (HRQOL) among older cancer survivors can be impaired by factors such as treatment, comorbidities, and social challenges. These HRQOL impairments may be especially pronounced in rural areas, where older adults have higher cancer burden and more comorbidities and risk factors for poor health. This study aimed to assess rural-urban differences in HRQOL for older cancer survivors and controls.

METHODS

Data came from Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS), which links cancer incidence from 18 U.S. population-based cancer registries to survey data for Medicare Advantage Organization enrollees (1998-2014). HRQOL measures were 8 standardized subscales and 2 global summary measures. We matched (2:1) controls to breast, colorectal, lung, and prostate cancer survivors, creating an analytic dataset of 271,640 participants (ages 65+). HRQOL measures were analyzed with linear regression models including multiplicative interaction terms (rurality by cancer status), controlling for sociodemographics, cohort, and multimorbidities.

RESULTS

HRQOL scores were higher in urban than rural areas (e.g., global physical component summary score for breast cancer survivors: urban mean = 38.7, standard error [SE] = 0.08; rural mean = 37.9, SE = 0.32; p < 0.05), and were generally lower among cancer survivors compared to controls. Rural cancer survivors had particularly poor vitality (colorectal: p = 0.05), social functioning (lung: p = 0.05), role limitation-physical (prostate: p < 0.01), role limitation-emotional (prostate: p < 0.01), and global mental component summary (prostate: p = 0.02).

CONCLUSION

Supportive interventions are needed to increase physical, social, and emotional HRQOL among older cancer survivors in rural areas. These interventions could target cancer-related stigma (particularly for lung and prostate cancers) and/or access to screening, treatment, and ancillary healthcare resources.

What are the contextual risk factors for low colorectal cancer screening uptake in El Paso County, Texas? Spatial cross-sectional analysis

OBJECTIVE

This study examines the geographical and socioeconomic factors associated with uptake of colorectal cancer (CRC) screening (colonoscopies or faecal immunochemical test (FIT) testing).

DESIGN

Secondary data analysis.

SETTING

The Against Colorectal Cancer in our Community (ACCION) programme was implemented in El Paso County, Texas, to increase screening rates among the uninsured and underinsured.

PARTICIPANTS

We successfully geocoded 5777 who were offered a free colonoscopy or FIT testing kit.

PRIMARY OUTCOME MEASURE

Census-tract CRC screening uptake average.

RESULTS

Medicare recipient mortality (β=0.409, p-value=0.049) and % 65 years or older (β=-0.577, p value=0.000) were significant census tract contextual factors that were associated with the prevalence of CRC screening uptake in the geographically weighted Poisson regression. Neither Latino ethnicity nor immigrant concentration were significant predictors of CRC screening uptake in the ACCION programme. Hot spot analysis demonstrated that there was a significant low-value cluster in South Central El Paso. There was a similar hot spot for % 65 years or older in this same area, suggesting that uptake was lowest in an area that had the highest concentration of older adults.

CONCLUSION

The results from this study revealed not only feasibility of hot spot analysis but also its utility in geographically tracking successful CRC screening uptake in cancer prevention and intervention programmes.

Comparative cost-effectiveness of mailed fecal immunochemical testing (FIT)-based interventions for increasing colorectal cancer screening in the Medicaid population

BACKGROUND

Mailed reminders to promote colorectal cancer (CRC) screening by fecal immunochemical testing (FIT) have been shown to be effective in the Medicaid population, in which screening is underused. However, little is known regarding the cost-effectiveness of these interventions, with or without an included FIT kit.

METHODS

The authors conducted a cost-effectiveness analysis of a randomized controlled trial that compared the effectiveness of a reminder + FIT intervention versus a reminder-only intervention in increasing FIT screening. The analysis compared the costs per person screened for CRC screening associated with the reminder + FIT versus the reminder-only alternative using a 1-year time horizon. Input data for a cohort of 35,000 unscreened North Carolina Medicaid enrollees ages 52 to 64 years were derived from the trial and microcosting. Inputs and outputs were estimated from 2 perspectives-the Medicaid/state perspective and the health clinic/facility perspective-using probabilistic sensitivity analysis to evaluate uncertainty.

RESULTS

The anticipated number of CRC screenings, including both FIT and screening colonoscopies, was higher for the reminder + FIT alternative (n = 8131; 23.2%) than for the reminder-only alternative (n = 5533; 15.8%). From the Medicaid/state perspective, the reminder + FIT alternative dominated the reminder-only alternative, with lower costs and higher screening rates. From the health clinic/facility perspective, the reminder + FIT versus the reminder-only alternative resulted in an incremental cost-effectiveness ratio of $116 per person screened.

CONCLUSIONS

The reminder + FIT alternative was cost saving per additional Medicaid enrollee screened compared with the reminder-only alternative from the Medicaid/state perspective and likely cost-effective from the health clinic/facility perspective. The results also demonstrate that health departments and state Medicaid programs can efficiently mail FIT kits to large numbers of Medicaid enrollees to increase CRC screening completion.

Trends in Mortality Due to Cancer in the United States by Age and County-Level Income, 1999-2015

Disparities in cancer mortality by county-level income have increased. It is unclear whether these widening disparities have affected older and younger adults equally. National death certificate data were utilized to ascertain cancer deaths during 1999-2015. Average annual percent changes in mortality rates and mortality rate ratios (RRs) were estimated by county-level income quintile and age (25-64 vs ≥65 years). Among 25- to 64-year-olds, cancer mortality rates were 30% higher (RR = 1.30, 95% confidence interval [CI] = 1.29 to 1.31) in the lowest-vs the highest-income counties in 1999-2001 and 56% higher (RR = 1.56, 95% CI = 1.55 to 1.57) in 2013-2015; the disparities among those 65 years and older were smaller but also widened over time (RR1999-2001 = 1.04, 95% CI = 1.03 to 1.05; RR2013-2015 = 1.14, 95% CI = 1.13 to 1.14). Widening disparities occurred across cancer sites. If all counties had the mortality rates of the highest-income counties, 21.5% of cancer deaths among 25- to 64-year-olds and 7.3% of cancer deaths in those 65 years and older would have been avoided in 2015. These results highlight an ongoing need for equity-focused interventions, particularly among younger adults.

Psychological and neighborhood factors associated with urban women's preventive care use

Women are more likely than men to forego care-including preventive care. Understanding which factors influence women's preventive care use has the potential to improve health. This study focuses on the largely understudied areas of psychological barriers (depression) and neighborhood factors (support and stressors) that may be associated with women's preventive care use through secondary analysis of the Chicago Community Adult Health Study. Across models, 30-40% of the variance in preventive care adherence was explained by the neighborhood. Depressive symptoms were not associated with preventive care use when neighborhood factors were included. However, stratified models showed that associations varied by race/ethnicity. Previous research has tended to focus on individual determinants of care, but this study suggests that barriers to care are far more complex. Efforts aimed at improving care utilization need to be multipronged and interventions need to take an individual's demographics, mental health, and context into account.

Colonoscopy videos on YouTube: Are they a good source of patient education?

Background and study aims  Colonoscopy is an effective tool to prevent colorectal cancer. Social media has emerged as a source of medical information for patients.YouTube (a video sharing website) is the most popular video informative source. Therefore, we aimed to assess the educational quality of colonoscopy videos available on YouTube. Methods  We performed a YouTube search using the keyword "colonoscopy" yielded 429 videos, of which 255 met the inclusion criteria. Colonoscopy Data Quality Score (C-DQS) was created to rate the quality of the videos (-10 to +40 points) based on a colonoscopy education video available on the Ameican Society of Gastrointestinal Endoscopy (ASGE) website. Each video was scored by six blinded reviewers independently using C-DQS. The Global Quality Score (GQS) was used for score validation. The intraclass correlation coefficient (ICC) was used to assess the similarity of the scores among reviewers. Results  Professional societies had the highest number of videos (44.3 %). Videos from professional societies (6.94) and media (6.87) had significantly higher mean C-DQS compared to those from alternative medicine providers (1.19), companies (1.16), and patients (2.60) ( P  < 0.05). Mean C-DQS score of videos from healthcare providers (4.40) was not statistically different than other sources. There was a high degree of agreement among reviewers for the videos from all sources (ICC = 0.934; P  < 0.001). Discussion  YouTube videos are a poor source of information on colonoscopy. Professional societies and media are better sources of quality information for patient education on colonoscopy. The medical community may need to engage actively in enriching the quality of educational material available on YouTube.

Variation of colorectal, breast and prostate cancer screening activity in Switzerland: Influence of insurance, policy and guidelines

Variation in utilization of healthcare services is influenced by patient, provider and healthcare system characteristics. It could also be related to the evidence supporting their use, as reflected in the availability and strength of recommendations in clinical guidelines. In this study, we analyzed the geographic variation of colorectal, breast and prostate cancer screening utilization in Switzerland and the influence of available guidelines and different modifiers of access. Colonoscopy, mammography and prostate specific antigen (PSA) testing use in eligible population in 2014 was assessed with administrative claims data. We ran a multilevel multivariable logistic regression model and calculated Moran's I and regional level median odds ratio (MOR) statistics to explore residual geographic variation. In total, an estimated 8.1% of eligible persons received colonoscopy, 22.3% mammography and 31.3% PSA testing. Low deductibles, supplementary health insurance and enrollment in a managed care plan were associated with higher screening utilization. Cantonal breast cancer screening programs were also associated with higher utilization. Spatial clustering was observed in the raw regional utilization of all services, but only for prostate cancer screening in regional residuals of the multilevel model. MOR was highest for prostate cancer screening (1.24) and lowest for colorectal cancer screening (1.16). The reasons for the variation of the prostate cancer screening utilization, not recommended routinely without explicit shared decision-making, could be further investigated by adding provider characteristics and patient preference information. This first cross-comparison of different cancer screening patterns indicates that the strength of recommendations, mediated by specific health policies facilitating screening, may indeed contribute to variation.

Public perception of predictive cancer genetic testing and research in Oregon

The potential for using widespread genetic testing to inform health care has become a viable option, particularly for heritable cancers. Yet, little is known about how to effectively communicate the benefits and risks of both personal genetic testing and participation in biorepositories that aid scientific advancements. Nationwide efforts are engaging communities in large genetic studies to better estimate the population-wide prevalence of heritable cancers but have been met with hesitance or declination to participate in some communities. To successfully engage an Oregon population in longitudinal research that includes predictive genetic testing for pathogenic or likely pathogenic variants associated with an increased risk for cancer, researchers conducted 35 focus groups (two of which were held in Spanish) in 24 of Oregon's 36 counties to better understand knowledge and attitudes related to genetic testing and willingness to participate in longitudinal genetic research. A total of 203 adults (mean = 45.6 years; range 18-88), representing a range of education levels and prior knowledge of genetic research, participated in the focus groups. The majority (85%) of participants reported personal or family diagnoses of cancer (e.g., self, family, friends). A majority (87%) also reported a strong interest in cancer genetic testing and receiving genetic information about themselves. Nearly all focus groups (94%, 33 of 35 sites) included participant discussion citing their families (e.g., children, close relatives, and extended family members) as key motivators for participation in genetic research. For example, participants reported interest in increasing personal knowledge about their own and their families' cancer risks in order to respond proactively, if a pathogenic variant was found. While most focus groups (94%, 33 of 35 sites) included participant discussion describing barriers to predictive genetic, testing such as concerns about outcomes, the desire to learn about health risks in oneself mitigated or outweighed those fears for many participants. Other commonly reported concerns were related to potential mistrust of insurance companies, researchers, or institutions, or lack of knowledge about genetics, genetic testing, or genetic research. Participants, particularly in rural areas, highlighted critical factors for research recruitment, such as trust, personal interaction, public education about genetic research, and clear communication about study goals and processes. Our statewide findings reflect that public interest in predictive cancer genetic testing and cancer genetic research can surpass lack of knowledge of the complex topics, particularly when benefits for self and family are emphasized and when study considerations are well articulated.

Predictive factors for non-participation or partial participation in breast, cervical and colorectal cancer screening programmes†

BACKGROUND

No study has investigated factors associated with non-participation or partial participation in the different combination patterns of screening programmes for all three cancers, that is, breast, colorectal and cervical cancer.

METHODS

In a retrospective cohort study, we sought to describe combinations of cancer screening participation rates among women in the Val-de-Marne area of France and to identify individual and contextual factors associated with non-participation or partial participation.

RESULTS

Women aged between 50 and 65 and who were eligible for all three screening programmes (n = 102 219) were analysed in multilevel logistic models, with the individual as the Level 1 variable and the place of residence as the Level 2 variable. The women who did not participate in any of the screening programmes were 34.4%, whereas 30.1%, 24% and 11.5% participated in one, two or all three screening programmes, respectively. Age below 55, a previous false-positive mammography, prior opportunistic mammography only, no previous mammography, membership of certain health insurance schemes (all P < 0.05) and residence in a deprived area (P < 0.001) were independently associated with non-participation or partial participation. We observed a stronger effect of deprivation on non-participation in all three cancers than in combinations of screening programmes.

CONCLUSION

Our findings suggest that the health authorities should focus on improving cancer screenings in general rather than screenings for specific types of cancer, especially among younger women and those living in the most socially deprived areas.

Initiation of Colorectal Cancer Screening Among Medicaid Enrollees

INTRODUCTION

Few studies have explored how individual- and practice-level factors influence colorectal cancer screening initiation among Medicaid enrollees newly age eligible for colorectal cancer screening (i.e., turning 50 years). This study explored colorectal cancer screening initiation among newly age-eligible Medicaid enrollees in Oregon.

METHODS

Medicaid claims data (January 2013 to June 2015) were used to conduct multivariable logistic regression (in 2018 and 2019) to explore individual- and practice-level factors associated with colorectal cancer screening initiation among 9,032 Medicaid enrollees.

RESULTS

A total of 17% of Medicaid enrollees initiated colorectal cancer screening; of these, 64% received a colonoscopy (versus fecal testing). Colorectal cancer screening initiation was positively associated with turning 50 years in 2014 (versus 2013; OR=1.21), being Hispanic (versus non-Hispanic white; OR=1.41), urban residence (versus rural; OR=1.23), and having 4 to 7 (OR=1.90) and 8 or more (OR=2.64) primary care visits compared with 1 to 3 visits in the year after turning 50 years. Having 3 or more comorbidities was inversely associated with initiation (OR=0.75). The odds of screening initiation were also higher for practices with 3 to 4 (OR=1.26) and 8 or more (OR=1.34) providers compared with 1 to 2 providers, and negatively associated with percentage of Medicaid panel age eligible for colorectal cancer screening (OR=0.92).

CONCLUSIONS

Both individual- and practice-level factors are associated with disparities in colorectal cancer screening initiation among Oregon Medicaid enrollees. Future work promoting colorectal cancer screening might focus on additional barriers to the timely initiation of colorectal cancer screening and explore the effect of practice in-reach and population outreach strategies.

The potential impact of the Affordable Care Act and Medicaid expansion on reducing colorectal cancer screening disparities in African American males

Few investigations have explored the potential impact of the Affordable Care Act on health disparity outcomes in states that chose to forgo Medicaid expansion. Filling this evidence gap is pressing as Congress grapples with controversial healthcare legislation that could phase out Medicaid expansion. Colorectal cancer (CRC) is a commonly diagnosed, preventable cancer in the US that disproportionately burdens African American men and has substantial potential to be impacted by improved healthcare insurance coverage. Our objective was to estimate the impact of the Affordable Care Act (increasing insurance through health exchanges alone or with Medicaid expansion) on colorectal cancer outcomes and economic costs among African American and White males in North Carolina (NC), a state that did not expand Medicaid. We used an individual-based simulation model to estimate the impact of ACA (increasing insurance through health exchanges alone or with Medicaid expansion) on three CRC outcomes (screening, stage-specific incidence, and deaths) and economic costs among African American and White males in NC who were age-eligible for screening (between ages 50 and 75) during the study period, years of 2013–2023. Health exchanges and Medicaid expansion improved simulated CRC outcomes overall, though the impact was more substantial among AAs. Relative to health exchanges alone, Medicaid expansion would prevent between 7.1 to 25.5 CRC cases and 4.1 to 16.4 per 100,000 CRC cases among AA and White males, respectively. Our findings suggest policies that expanding affordable, quality healthcare coverage could have a demonstrable, cost-saving impact while reducing cancer disparities.

Estimating the impact of insurance expansion on colorectal cancer and related costs in North Carolina: A population-level simulation analysis

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 Medicaid expansion, and Medicare-for-all. The insurance expansion scenarios would increase percent up-to-date with screening by 0.3 and 7.1 percentage points for Medicaid expansion and Medicare-for-all, respectively, while insurance reduction would reduce percent up-to-date by 1.1 percentage points, compared to the status quo (51.7% up-to-date), at the end of the 5-year period. Throughout these individuals' lifetimes, this change in CRC screening/testing results in an estimated 498 CRC cases averted with Medicaid expansion and 6031 averted with Medicare-for-all, and an additional 1782 cases if health insurance gains associated with ACA are lost. Estimated cost savings - balancing increased CRC screening/testing costs against decreased cancer treatment costs - are approximately $30 M and $970 M for Medicaid expansion and Medicare-for-all scenarios, respectively, compared to status quo. Insurance expansion is likely to improve CRC screening both overall and in underserved populations while saving money, with the largest savings realized by Medicare.

Mailed FIT (fecal immunochemical test), navigation or patient reminders? Using microsimulation to inform selection of interventions to increase colorectal cancer screening in Medicaid enrollees

Colorectal cancer (CRC) can be effectively prevented or detected with guideline concordant screening, yet Medicaid enrollees experience disparities. We used microsimulation to project CRC screening patterns, CRC cases averted, and life-years gained in the population of 68,077 Oregon Medicaid enrollees 50-64 over a five year period starting in January 2019. The simulation estimated the cost-effectiveness of five intervention scenarios - academic detailing plus provider audit and feedback (Detailing+), patient reminders (Reminders), mailing a Fecal Immunochemical Test (FIT) directly to the patient's home (Mailed FIT), patient navigation (Navigation), and mailed FIT with Navigation (Mailed FIT + Navigation) - compared to usual care. Each intervention scenario raised CRC screening rates compared to usual care, with improvements as high as 11.6 percentage points (Mailed FIT + Navigation) and as low as 2.5 percentage points (Reminders) after one year. Compared to usual care, Mailed FIT + Navigation would raise CRC screening rates 20.2 percentage points after five years - averting nearly 77 cancer cases (a reduction of 113 per 100,000) and exceeding national screening targets. Over a five year period, Reminders, Mailed FIT and Mailed FIT + Navigation were expected to be cost effective if stakeholders were willing to pay $230 or less per additional year up-to-date (at a cost of $22, $59, and $227 respectively), whereas Detailing+ and Navigation were more costly for the same benefits. To approach national CRC screening targets, health system stakeholders are encouraged to implement Mailed FIT with or without Navigation and Reminders.

Correlates of colorectal cancer screening rates in primary care clinics serving low income, medically underserved populations

INTRODUCTION

Screening for colorectal cancer (CRC) is effective in reducing CRC burden. Primary care clinics have an important role in increasing screening. We investigated associations between clinic-level CRC screening rates of the clinics serving low income, medically underserved population, and clinic-level screening interventions, clinic characteristics and community contexts.

METHODS

Using data (2015-16) from the Centers for Disease Control and Prevention's (CDC) Colorectal Cancer Control Program, we linked clinic-level data with county-level contextual data from external sources. Analysis variables included clinic-level CRC screening rates, four different evidence-based interventions (EBIs) intended to increase screening, clinic characteristics, and clinic contexts. In the analysis (2018), we used weighted ordinary least square multiple regression analyses to associate EBIs and other covariates with clinic-level screening rates.

RESULTS

Clinics (N = 581) had an average screening rate of 36.3% (weighted. Client reminders had the highest association (5.6 percentage points) with screening rates followed by reducing structural barriers (4.9 percentage points), provider assessment and feedback (3.2 percentage points), and provider reminders (<1 percentage point). Increases in the number of EBIs was associated with steady increases in the screening rate (5.4 percentage points greater for one EBI). Screening rates were 16.4 percentage points higher in clinics with 4 EBIs vs. no EBI. Clinic characteristics, contexts (e.g. physician density), and context-EBI interactions were also associated with clinic screening rates.

CONCLUSIONS

These results may help clinics, especially those serving low income, medically underserved populations, select individual or combinations of EBIs suitable to their contexts while considering costs.

Breast, Cervical, and Colorectal Cancer Screening: Patterns Among Women With Medicaid and Commercial Insurance

INTRODUCTION

Despite healthcare reforms mandating expanded insurance coverage and reduced out-of-pocket costs for preventive care, cancer screening rates remain relatively static. No study has measured cancer screening rates for multiple tests among non-Medicare patients.

METHODS

This retrospective, population-based claims analysis, conducted in 2016-2017, of commercially insured and Medicaid-insured women aged 30-59 years enrolled in IBM MarketScan Commercial and Medicaid Databases (containing approximately 90 and 17 million enrollees, respectively) during 2010-2015 describes screening rates for breast, cervical, and colorectal cancer. Key outcomes were (1) proportion screened for breast, cervical, and colorectal cancer among the age-eligible population compared with accepted age-based recommendations and (2) proportion with longer-than-recommended intervals between tests.

RESULTS

One half (54.7%) of commercially insured women aged 40-59 years (n=1,538,444) were screened three or more times during the 6-year study period for breast cancer; for Medicaid-insured women (n=78,897), the rates were lower (23.7%). One third (43.4%) of commercially insured and two thirds (68.9%) of Medicaid-insured women had a >2.5-year gap between mammograms. Among women aged 30-59 years, 59.3% of commercially insured women and 31.4% of Medicaid-insured women received two or more Pap tests. The proportion of patients with a >3.5-year gap between Pap tests was 33.9% (commercially insured) and 57.1% (Medicaid-insured). Among women aged 50-59 years, 63.3% of commercially insured women and 47.2% of Medicaid-insured women were screened at least one time for colorectal cancer. Almost all women aged 30-59 years (commercially insured, 99.1%; Medicaid-insured, 98.9%) had at least one healthcare encounter.

CONCLUSIONS

Breast and cervical cancer screenings remain underutilized among both commercially insured and Medicaid-insured populations, with lower rates among the Medicaid-insured population. However, almost all women had at least one healthcare encounter, suggesting opportunities for better coordinated care.

Colorectal cancer knowledge and screening adherence among low-income Hispanic employees

Hispanics have the lowest colorectal cancer (CRC) screening rates of all racial/ethnic groups and comprise the largest proportion of low-income manual laborers in the nation. We partnered with businesses to implement a community health worker (CHW)-led intervention among Hispanic workers in service-related and manual labor occupations, which often pay low wages and do not provide health insurance. CHWs measured knowledge, screening adherence and perceptions of CRC risk before and after educational interventions via interview. CHWs provided fecal immunochemical tests (FITs) to participants aged ≥50 years. Chi-square tests and logistic regression identified pre-intervention predictors of CRC knowledge of all participants and adherence among eligible participants. Adherence among participants increased from 40% (n = 307) pre-intervention to 66% post-intervention. Knowledge about CRC was associated with age ≥50 years (OR = 8.90 [95% CI = 2.61-30.35]; ref = 18-30) and perceived personal risk for CRC (Likely, OR = 3.06 [95% CI = 1.40-6.67]; ref = Not likely). Insurance status was associated with screening adherence pre-intervention (OR = 3.00 [95% CI 1.10-8.12]; ref = No insurance). Improvement in adherence post-intervention was associated with income between $25 000 and ≥$55 000 (OR = 8.49 [95% CI 1.49-48.32]; ref = $5000-<$10 000). Community-based health programs can improve CRC screening adherence among Hispanic workers in service-related and manual labor positions, but lowest-income workers may need additional support.

Clinicopathologic and epidemiological characteristics of prognostic factors in post-surgical survival of colorectal cancer patients in Jiangsu Province, China

Poor survival among colorectal cancer (CRC) patients has been widely associated with clinico-epidemiological features and treatment regimen. In Jiangsu (China), however, it is not known which one of the prognostic factors explains the survival disparities among patients with CRC. This prospective study using 1078 patients (stages I-IV) that underwent surgery at Jiangsu Hospital, explored the relevant factors affecting the prognoses of right-side colon cancer (RCC), left-side colon cancer (LCC) and rectal cancer (ReC) patients. Of these cases, 234 (21.7%), 241 (22.4%) and 603 (55.9%) were found to have RCC, LCC and ReC respectively. Compared to LCC, RCC exhibited a greater proportion of older patients, poorly differentiated carcinomas, higher T-stage and higher TNM-stage. The overall survival (OS) for RCC was 60 vs.78 or 77 months for LCC or ReC respectively (P = 0.030). There were no significant differences in OS between LCC and ReC across the subgroups (P = 0.633). In multivariate analysis, RCC patients had age (>60 vs. ≤60 years, HR = 1.529, P = 0.019), N-stage (N1 vs. N0, HR = 4.056, P = 0.012) and M-stage (M1 vs. M0, HR = 3.442, P < 0.0001) as independent prognostic factors, whereas smoking status was found to be a predictor of mortality (smoker vs. nonsmoker, HR = 2.343, P = 0.017) for LCC. In addition, age (>60 vs. ≤60 years, HR = 2.199, P < 0.0001), alcohol consumption (drinker vs. nondrinker, HR = 0.510, P = 0.034), tumor grade (Poor vs. well/moderate, HR = 2.759, P = 0.031) and T-stage (T3-4 vs. T1-2, HR = 1.742, P < 0.0001) were found to be predictors of mortality for ReC. There were significant pairwise interactions across subgroups. Furthermore, significant differences were observed for LCC vs. RCC (OS, HR = 0.783, P = 0.039), but no statistically significant differences for ReC vs. RCC (P = 0.149) and LCC vs. ReC (P = 0.355). Nevertheless, significant differences remained between ReC vs. RCC for male (HR = 0.591, P = 0.009), drinker (HR = 0.396, P = 0.005), rural resident (HR = 0.437,P = 0.022), tumor grade (well/moderate, HR = 0.475, P = 0.022), T-stage (T1-2, HR = 0.362, P = 0.001), N-stage (N0, HR = 0.604, P = 0.011), M-stage(M0, HR = 0.401, P = 0.006) and TNM-stage (I-II, HR = 0.567, P = 0.005). Statistically significant differences were observed for LCC vs. RCC for gender (female, HR = 0.495, P = 0.003) and T-stage (T1-2, HR = 0.417, P = 0.010) as well as for LCC vs. ReC in patients with smoking habits (HR = 1.951, P = 0.002) and M-stage (M0, HR = 2.291, P = 0.003). These findings suggest that the variations in CRC post-surgical survival in China may be primarily explained with the clinicopathologic features and epidemiological characteristic of the patients. Patients with RCC had significantly worse OS compared to both LCC and ReC in several subgroups.

Colonoscopy and Sigmoidoscopy Use among the Average-Risk Population for Colorectal Cancer: A Systematic Review and Trend Analysis

Monitoring population-level colonoscopy and sigmoidoscopy use is crucial to estimate the future burden of colorectal cancer and guide screening efforts. We conducted a systematic literature search on colonoscopy and sigmoidoscopy use, published between November 2016 and December 2018 in the databases PubMed and Web of Science to update previous reviews and analyze time trends for various countries. In addition, we used data from the German and European Health Interview Surveys and the National Health Interview Survey to explore recent time trends for Germany and the US, respectively. The literature search yielded 23 new articles: fourteen from the US and nine from Australia, Canada, England, Germany, Saudi Arabia, and South Korea. Colonoscopy use within 10 years was highest and, apart from the youngest age groups eligible for colorectal cancer screening, kept increasing to levels close to 60% in the US and Germany. A recent steep increase was also observed for South Korea. Limited data were available on sigmoidoscopy use; regional studies from the US suggest that sigmoidoscopy has become rarely used. Despite high uptake and ongoing increase in the US, Germany, and South Korea, use of colonoscopy and sigmoidoscopy has either remained low or essentially unknown for the majority of countries.

Changes in Breast and Colorectal Cancer Screening After Medicaid Expansion Under the Affordable Care Act

INTRODUCTION

Medicaid expansions following the Affordable Care Act have improved insurance coverage in low-income adults, but little is known about its impact on cancer screening. This study examined associations between Medicaid expansion timing and colorectal cancer (CRC) and breast cancer (BC) screening.

METHODS

Up-to-date and past 2-year CRC (n=95,400) and BC (women, n=43,279) screening prevalence were computed among low-income respondents aged 50-64 years in 2012, 2014, and 2016 Behavioral Risk Factor Surveillance System data. Respondents were grouped according to Medicaid expansion timing as: very early ([VE] six states expanding March 1, 2010-April 14, 2011), early (21 states expanding January 1, 2014-August 15, 2014), late (five states expanding January 1, 2015-July 1, 2016), and non-expansion states (19 states). Absolute adjusted difference-in-differences (aDDs) were computed in 2018-2019 (ref, non-expansion states).

RESULTS

Between 2012 and 2016, absolute up-to-date CRC screening increased by 8.8%, 2.9%, 2.4%, and 3.8% among low-income adults in VE, early, late, and non-expansion states, respectively. Past 2-year CRC screening increased by 8.0% in VE and 2.8% in non-expansion states, with an aDD of 4.9% (p=0.041). In 2012-2016, up-to-date BC screening increased by 5.1%, 4.9%, and 3.7% among low-income women in VE, early, and non-expansion states, respectively, but aDDs were not statistically significant.

CONCLUSIONS

Prevalence of CRC and BC screening among low-income adults rose in Medicaid expansion states, though increases were significantly higher than those in non-expansion states only for recent CRC screening in VE expansion states. Large-scale improvements in cancer screening may take several years following expansion in access to care.

Providing Higher Resolution Indicators of Rurality in the Surveillance, Epidemiology, and End Results (SEER) Database: Implications for Patient Privacy and Research

BACKGROUND

The burden of cancer is higher in rural areas than urban areas. The NCI's Surveillance, Epidemiology, and End Results (SEER) database currently provides county-level information on rurality for cancer patients in its catchment area, but more nuanced measures of rurality would improve etiologic and surveillance studies.

METHODS

We analyzed disclosure risk and conducted a sample utility analysis of census tract-level measures of rurality, using (1) U.S. Department of Agriculture's Rural Urban Commuting Area (RUCA) codes and (2) U.S. Census data on percentage of the population living in nonurban areas. We evaluated the risk of disclosure by calculating the percentage of census tracts and cancer cases that would be uniquely identified by a combination of these two rurality measures with a census tract-level socioeconomic status (SES) variable. The utility analyses examined SES disparities across levels of rurality for lung and breast cancer incidence and relative survival.

RESULTS

Risk of disclosure was quite low: <0.03% of census tracts and <0.03% of cancer cases were uniquely identified. Utility analyses demonstrated an SES gradient in lung and breast cancer incidence and survival, with relatively similar patterns across rurality variables.

CONCLUSIONS

The RUCA and Census rurality measures have been added to a specialized SEER 18 database. Interested researchers can request access to this database to perform analyses of urban/rural differences in cancer incidence and survival.

IMPACT

Such studies can provide important research support for future interventions to improve cancer prevention and control.

Factors Associated With Minimally Invasive Surgery for Colorectal Cancer in Emergency Settings

BACKGROUND

Minimally invasive surgery (MIS) is associated with improved colorectal cancer (CRC) outcomes, but it is used less frequently in emergency settings. We aimed to assess patient-level factors associated with emergency presentation for CRC and the use of MIS in emergency versus elective settings.

METHODS

This retrospective study examined the clinical data of patients who underwent emergency and elective resections for CRC from 2013 to 2015 using the Florida Inpatient Discharge Dataset. Multivariable analyses were performed to assess differences in gender, age, race, urbanization, region, insurance, and clinical characteristics associated with mode of presentation and surgical approach. In-hospital mortality and length of stay by mode of presentation were recorded.

RESULTS

Of 16,277 patients identified, 10,224 (61%) had elective surgery and 6503 (39%) had emergency surgery. Emergency presentations were more likely to be black (14.2% versus 9.5%), Hispanic (18.9% versus 15.4%), Medicaid-insured (9.7% versus 4.2%), and have metastatic cancer (34.4% versus 20.2%) or multiple comorbidities (12.6% versus 4.0%). MIS was the surgical approach in 31.8% of emergency cases versus 48.1% of elective cases. Factors associated with lower odds of MIS for emergencies include Medicaid (odds ratio (OR) 0.79, 95% confidence interval (CI) 0.63-0.99), metastases (OR 0.56, CI 0.5-0.63), and multiple comorbidities (OR 0.53, CI 0.4-0.7). Emergency cases experienced higher in-hospital mortality (3.7% versus 1.0%) and a longer median length of stay (10 d versus 5 d).

CONCLUSIONS

Emergency CRC presentations are associated with racial minorities, Medicaid insurance, metastatic disease, and multiple comorbidities. Odds of MIS in emergency settings are lowest for patients with Medicaid insurance and highest clinical disease burden.

Colorectal cancer screening in newly insured Medicaid members: a review of concurrent federal and state policies

BACKGROUND

Colorectal cancer (CRC) screening is underutilized by Medicaid enrollees and the uninsured. Multiple national and state policies were enacted from 2010 to 2014 to increase access to Medicaid and to promote CRC screening among Medicaid enrollees. We aimed to determine the impact of these policies on screening initiation among newly enrolled Oregon Medicaid beneficiaries age-eligible for CRC screening.

METHODS

We identified national and state policies affecting Medicaid coverage and preventive services in Oregon during 2010-2014. We used Oregon Medicaid claims data from 2010 to 2015 to conduct a cohort analysis of enrollees who turned 50 and became age-eligible for CRC screening (a prevention milestone, and an age at which guideline-concordant screening can be assessed within a single year) during each year from 2010 to 2014. We calculated risk ratios to assess whether first year of Medicaid enrollment and/or year turned 50 was associated with CRC screening initiation.

RESULTS

We identified 14,576 Oregon Medicaid enrollees who turned 50 during 2010-2014; 2429 (17%) completed CRC screening within 12 months after turning 50. Individuals newly enrolled in Medicaid in 2013 or 2014 were 1.58 and 1.31 times more likely, respectively, to initiate CRC screening than those enrolled by 2010. A primary care visit in the calendar year, having one or more chronic conditions, and being Hispanic was also associated with CRC screening initiation.

DISCUSSION

The increased uptake of CRC screening in 2013 and 2014 is associated with the timing of policies such as Medicaid expansion, enhanced federal matching for preventive services offered to Medicaid enrollees without cost sharing, and formation of Medicaid accountable care organizations, which included CRC screening as an incentivized quality metric.

Data-Powered Participatory Decision Making: Leveraging Systems Thinking and Simulation to Guide Selection and Implementation of Evidence-Based Colorectal Cancer Screening Interventions

A robust evidence base supports the effectiveness of timely colorectal cancer (CRC) screening, follow-up of abnormal results, and referral to care in reducing CRC morbidity and mortality. However, only two-thirds of the US population is current with recommended screening, and rates are much lower for those who are vulnerable because of their race/ethnicity, insurance status, or rural location. Multiple, multilevel factors contribute to observed disparities, and these factors vary across different populations and contexts. As highlighted by the Cancer Moonshot Blue Ribbon Panel working groups focused on Prevention and Early Detection and Implementation Science inadequate CRC screening and follow-up represent an enormous missed opportunity in cancer prevention and control. To measurably reduce CRC morbidity and mortality, the evidence base must be strengthened to guide the identification of (1) multilevel factors that influence screening across different populations and contexts, (2) multilevel interventions and implementation strategies that will be most effective at targeting those factors, and (3) combinations of strategies that interact synergistically to improve outcomes. Systems thinking and simulation modeling (systems science) provide a set of approaches and techniques to aid decision makers in using the best available data and research evidence to guide implementation planning in the context of such complexity. This commentary summarizes current challenges in CRC prevention and control, discusses the status of the evidence base to guide the selection and implementation of multilevel CRC screening interventions, and describes a multi-institution project to showcase how systems science can be leveraged to optimize selection and implementation of CRC screening interventions in diverse populations and contexts.

Does a transition to accountable care in Medicaid shift the modality of colorectal cancer testing?

BACKGROUND

Health care reform is changing preventive services delivery. This study explored trajectories in colorectal cancer (CRC) testing over a 5-year period that included implementation of 16 Medicaid Accountable Care Organizations (ACOs, 2012) and Medicaid expansion (2014) - two provisions of the Affordable Care Act (ACA) - within the state of Oregon, USA.

METHODS

Retrospective analysis of Oregon's Medicaid claims for enrollee's eligible for CRC screening (50-64 years) spanning January 2010 through December 2014. Our analysis was conducted and refined April 2016 through June 2018. The analysis assessed the annual probability of patients receiving CRC testing and the modality used (e.g., colonoscopy, fecal testing) relative to a baseline year (2010). We hypothesized that CRC testing would increase following Medicaid ACO formation - called Coordinated Care Organizations (CCOs).

RESULTS

A total of 132,424 unique Medicaid enrollees (representing 255,192 person-years) met inclusion criteria over the 5-year study. Controlling for demographic and regional factors, the predicted probability of CRC testing was significantly higher in 2014 (+ 1.4 percentage points, p < 0.001) compared to the 2010 baseline but not in 2012 or 2013. Increased fecal testing using Fecal Occult Blood Tests (FOBT) or Fecal Immunochemical Tests (FIT) played a prominent role in 2014. The uptick in statewide fecal testing appears driven primarily by a subset of CCOs.

CONCLUSIONS

Observed CRC testing did not immediately increase following the transition to CCOs in 2012. However increased testing in 2014, may reflect a delay in implementation of interventions to increase CRC screening and/or a strong desire by newly insured Medicaid CCO members to receive preventive care.

Predictors of palliative treatment in stage IV colorectal cancer

BACKGROUND

Palliative treatment may be associated with prolonged survival and improved quality of life, but remains underutilized in stage IV colorectal (CRC). We examined a national cohort of stage IV CRC patients to determine the factors associated with palliative treatment.

METHODS

Stage IV CRC patients, classified based on their survival length (<6 months, 6-24 months, and 24 + months), were analyzed using the American College of Surgeons National Cancer Data Base (2004-2013). Multivariable analysis was performed to evaluate factors associated with palliative treatment.

RESULTS

Of 85,981 patients analyzed, 10.9% received palliative treatment. For 6-24 months survival, a more recent year of diagnosis, Medicaid, uninsured status, Mountain and Pacific regions were associated with higher odds of palliative treatment. For those who survived < 6months, older patients had lower odds, while academic centers and residence > 20 miles from treating institutions were associated with increased likelihood of palliative treatment.

CONCLUSIONS

Palliative treatment in stage IV CRC is associated with a more recent year of diagnosis, Medicaid, academic centers, Mountain and Pacific regions of the US.

Disparities in minimally invasive surgery for colorectal cancer in Florida

BACKGROUND

The cost of minimally invasive surgery (MIS) raises potential for racial and social disparities. The aim of this study was to identify the racial, socioeconomic and geographic disparities associated with MIS for colorectal cancer (CRC) in Florida.

METHODS

Using the Florida Inpatient Discharge Dataset, we examined the clinical data of patients who underwent elective resections for CRC during 2013-2015. Multivariable analysis was performed to identify differences in gender, age, race, urbanization, region, insurance and clinical characteristics associated with the surgical approach.

RESULTS

Of the 10,224 patients identified, 5308 (52%) had open surgery and 4916 (48%) had MIS. Females (p = 0.012), Medicare-insured patients (p = 0.001) and residents of South Florida were more likely to undergo MIS. Patients with Medicaid (p = 0.008), metastasis (p < 0.001) or 3-5 comorbidities (p = 0.004) had reduced likelihood of MIS. Hispanic patients in Southwest Florida had reduced likelihood of receiving MIS than whites (p < 0.017). Patients who underwent MIS had significantly reduced LOS (p < 0.001).

CONCLUSIONS

Consistent with national studies, MIS for CRC in Florida is associated with insurance status and geographic location. There are patient-level regional differences for racial disparities in MIS for CRC in Florida.

Comparative effectiveness of mailed reminders with and without fecal immunochemical tests for Medicaid beneficiaries at a large county health department: A randomized controlled trial

BACKGROUND

Colorectal cancer (CRC) screening is effective but underused. Screening rates are lower among Medicaid beneficiaries versus other insured populations. No studies have examined mailed fecal immunochemical testing (FIT)-based outreach programs for Medicaid beneficiaries.

METHODS

In a patient-level randomized controlled trial, a mailed CRC screening reminder plus FIT, sent from an urban health department to Medicaid beneficiaries, was compared with the same reminder without FIT. The reminder group could request FIT. Completed FIT kits were processed by the health department laboratory. Respondents were notified of normal results by mail. Abnormal results were given via phone by a patient navigator who provided counselling and assistance with follow-up care. The primary outcome was FIT return.

RESULTS

In all, 2144 beneficiaries at average CRC risk were identified, and there was no evidence of screening with Medicaid claims data. To the reminder+FIT group, 1071 were randomized, and 1073 were randomized to the reminder group; 307 (28.7%) in the reminder+FIT group and 347 (32.3%) in the reminder group were unreachable or ineligible (previous screening). The FIT return rate was significantly higher in the reminder+FIT group than the reminder group (21.1% vs 12.3%; difference, 8.8%; 95% confidence interval, 3.7%-13.9%; P < .01). Eighteen individuals (7.2%) who completed FIT tests had abnormal results, and 15 were eligible for follow-up colonoscopy; 66.7% (n = 10) completed follow-up colonoscopy.

CONCLUSIONS

A health department-based, mailed FIT program targeting Medicaid beneficiaries was feasible. Including a FIT kit resulted in greater screening completion than a reminder letter alone. Further research is needed to understand the comparative cost-effectiveness of these interventions.

Regionalization and Its Alternatives

This article begins by introducing the historical background surrounding the volume-outcomes relationship literature, particularly in complex cancer surgery. The state of evidence surrounding mortality, as well as other outcomes, in relation to both hospital and surgeon procedure volume is synthesized. Where it is understood, the level of adoption of regionalization of various complex surgeries in the United States is also presented. Various controversies are weighed and discussed. Finally, various models of regionalization and proposed alternatives to regionalization from the peer-reviewed literature are presented.

A systematic review of clinic and community intervention to increase fecal testing for colorectal cancer in rural and low-income populations in the United States - How, what and when?

BACKGROUND

Interventions to improve fecal testing for colorectal cancer (CRC) exist, but are not yet routine practice. We conducted this systematic review to determine how implementation strategies and contextual factors influenced the uptake of interventions to increase Fecal Immunochemical Tests (FIT) and Fecal Occult Blood Testing (FOBT) for CRC in rural and low-income populations in the United States.

METHODS

We searched Medline and the Cochrane Library from January 1998 through July 2016, and Scopus and clinicaltrials.gov through March 2015, for original articles of interventions to increase fecal testing for CRC. Two reviewers independently screened abstracts, reviewed full-text articles, extracted data and performed quality assessments. A qualitative synthesis described the relationship between changes in fecal testing rates for CRC, intervention components, implementation strategies, and contextual factors. A technical expert panel of primary care professionals, health system leaders, and academicians guided this work.

RESULTS

Of 4218 citations initially identified, 27 unique studies reported in 29 publications met inclusion criteria. Studies were conducted in primary care (n = 20, 74.1%), community (n = 5, 18.5%), or both (n = 2, 7.4%) settings. All studies (n = 27, 100.0%) described multicomponent interventions. In clinic based studies, components that occurred most frequently among the highly effective/effective study arms were provision of kits by direct mail, use of a pre-addressed stamped envelope, client reminders, and provider ordered in-clinic distribution. Interventions were delivered by clinic staff/community members (n = 10, 37.0%), research staff (n = 6, 22.2%), both (n = 10, 37.0%), or it was unclear (n = 1, 3.7%). Over half of the studies lacked information on training or monitoring intervention fidelity (n = 15, 55.6%).

CONCLUSIONS

Studies to improve FIT/FOBT in rural and low-income populations utilized multicomponent interventions. The provision of kits through the mail, use of pre-addressed stamped envelopes, client reminders and in-clinic distribution appeared most frequently in the highly effective/effective clinic-based study arms. Few studies described contextual factors or implementation strategies. More robust application of guidelines to support reporting on methods to select, adapt and implement interventions can help end users determine not just which interventions work to improve CRC screening, but which interventions would work best in their setting given specific patient populations, clinical settings, and community characteristics.

TRIAL REGISTRATION

In accordance with PRISMA guidelines, our systematic review protocol was registered with PROSPERO, the international prospective register of systematic reviews, on April 16, 2015 (registration number CRD42015019557 ).

"Finding the Right FIT": Rural Patient Preferences for Fecal Immunochemical Test (FIT) Characteristics

PURPOSE

Colorectal cancer (CRC) is the third leading cause of cancer death in the United States, yet 1 in 3 Americans have never been screened for CRC. Annual screening using fecal immunochemical tests (FITs) is often a preferred modality in populations experiencing CRC screening disparities. Although multiple studies evaluate the clinical effectiveness of FITs, few studies assess patient preferences toward kit characteristics. We conducted this community-led study to assess patient preferences for FIT characteristics and to use study findings in concert with clinical effectiveness data to inform regional FIT selection.

METHODS

We collaborated with local health system leaders to identify FITs and recruit age eligible (50 to 75 years), English or Spanish speaking community members. Participants completed up to 6 FITs and associated questionnaires and were invited to participate in a follow-up focus group. We used a sequential explanatory mixed-methods design to assess participant preferences and rank FIT kits. First, we used quantitative data from user testing to measure acceptability, ease of completion, and specimen adequacy through a descriptive analysis of 1) fixed response questionnaire items on participant attitudes toward and experiences with FIT kits, and 2) a clinical assessment of adherence to directions regarding collection, packaging, and return of specimens. Second, we analyzed qualitative data from focus groups to refine FIT rankings and gain deeper insight into the pros and cons associated with each tested kit.

FINDINGS

Seventy-six FITs were completed by 18 participants (Range, 3 to 6 kits per participant). Over half (56%, n = 10) of the participants were Hispanic and 50% were female (n = 9). Thirteen participants attended 1 of 3 focus groups. Participants preferred FITs that were single sample, used a probe and vial for sample collection, and had simple, large-font instructions with colorful pictures. Participants reported challenges using paper to catch samples, had difficulty labeling tests, and emphasized the importance of having care team members provide verbal instructions on test completion and follow-up support for patients with abnormal results. FIT rankings from most to least preferred were OC-Light, Hemosure iFOB Test, InSure FIT, QuickVue, OneStep+, and Hemoccult ICT.

CONCLUSIONS

FIT characteristics influenced patient's perceptions of test acceptability and feasibility. Health system leaders, payers, and clinicians should select FITs that are both clinically effective and incorporate patient preferred test characteristics. Consideration of patient preferences may facilitate FIT return, especially in populations at higher risk for experiencing CRC screening disparities.
