Improving Colorectal Cancer Screening in a Regional Safety-Net Health System over a 10-Year Period: Lessons for Population Health. J Gen Intern Med 2024; 39:978-984. [PMID: 37932541 PMCID: PMC11074086 DOI: 10.1007/s11606-023-08477-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 10/11/2023] [Indexed: 11/08/2023]
Abstract
BACKGROUND Despite national policy efforts to increase colorectal cancer (CRC) screening, rates in vulnerable populations remain suboptimal. Many types of interventions have been employed, but their impact on improving population-level rates of CRC screening over time is uncertain. OBJECTIVE Assess the impact of 10 years of different in-reach and outreach strategies to improve CRC screening and identify factors associated with being screen up-to-date (SUTD). DESIGN Observational cohort study. PARTICIPANTS Patients aged 50-74 years from 12 community-based primary care clinics in an integrated, regional safety-net health system. INTERVENTIONS Multiple system-level interventions were implemented over time (visit-based electronic health record [EHR] reminders, quality measurement, annual preventive service letters, and mailed fecal immunohistochemical stool tests [FIT]). MAIN MEASURES CRC SUTD rates by calendar year among those with a primary care (PC) visit in the prior 1 and 3 years and their multivariable correlates. KEY RESULTS The sample included 31,786-40,405 patients/year. In 2011, mean age was 58.9, 63.9% were women, 37.0% were Hispanic, 39.3% Black, 16.8% White, and 6.6% Asian/Other, and 60.5% were uninsured/Medicaid. Three-quarters of patients had ≥ 1 PC visit in the prior year. Lower-intensity interventions (EHR reminders, quality measurement, annual prevention letters) had limited impact on SUTD rates (2-3% rise). Implementing system-wide mailed FIT increased rates from 51.2 to 61.9% among those with a PC visit in the past year (40.5 to 46.8% with a PC visit ≤ 3 years). Stopping mailed FIT due to COVID wiped out these gains. Higher screening rates were associated with the following: older age; female; more comorbidities, PC clinic visits, and prior FITs; and better insurance coverage. Hispanics had the highest SUTD rates followed by Asians, Blacks, and Whites (p < 0.05). CONCLUSIONS Implementation of a system-wide mailed FIT program had the greatest impact on SUTD rates. Lower-intensity interventions (EHR reminders, quality measurement, and patient letters) had limited effects.

Clin Gastroenterol Hepatol 2023; 21:2759-2788.e6. [PMID: 36549469 PMCID: PMC10279803 DOI: 10.1016/j.cgh.2022.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 11/23/2022] [Accepted: 12/02/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND & AIMS Structural racism and discrimination (SRD) are important upstream determinants of health perpetuated by discriminatory laws and policies. Therefore, measuring SRD and its impact on health is critical to developing interventions that address resultant health disparities. We aimed to identify gastrointestinal (GI) or liver studies that report measures of SRD or interventions to achieve health equity in these domains by addressing upstream determinants of health. METHODS We conducted a scoping review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses scoping reviews guidelines. Studies that used an SRD measure or examined an upstream intervention in GI or liver disease were included. Studies that described health disparities in GI or liver conditions without mentioning SRD were excluded. Study characteristics, findings, and limitations were extracted. RESULTS Forty-six articles (19 studies using SRD measures and 27 studies of upstream interventions) were identified. Measures of residential racial segregation were reported most frequently. SRD was associated with poorer health outcomes for racial and ethnic minority populations. Although upstream intervention studies focused primarily on policies related to colon cancer screening and organ graft allocation, racial and ethnic disparities often persisted post-intervention. CONCLUSIONS To achieve health equity in GI and liver conditions, there is an urgent need for research that goes beyond describing health disparities to incorporating measures of SRD and implementing interventions that address this understudied determinant of health.

Abstract
Background: In Louisiana, colorectal cancer (CRC) incidence and mortality exceed national rates. Census tract, sex, and racial disparities across the state are well documented. This study examined whether there were subpopulation differences in associations between CRC screening, area deprivation index (ADI), and patient characteristics. Methods: This retrospective observational study included patients aged 50 to 75 years who received care within Ochsner Health in Louisiana between July 1, 2012, and December 31, 2020. Logistic regression models were used to generate adjusted odds ratios (95% CI). Results: A total of 75,344 patients met eligibility criteria for inclusion in the data analysis (60% female, 36% Black, 56% with spouse/partner, 42% Medicare/Medicaid,17% living in high deprivation areas, 41% with 2+ chronic conditions, 56% never smoked, 51% obese). Living in areas with less deprivation (state decile 1-3 vs 8-10: 1.19 [1.14-1.24]), number of comorbidities (3+ conditions: 1.15 [1.12-1.17]), and prior outpatient visits (1.63 [1.58-1.67]) increased odds of CRC screening. Male sex (0.82 [0.79-0.84]), age group 55 to 59 years (0.97 [0.95-0.99]), and Medicaid insurance (0.89 [0.86-0.92]) decreased odds of screening. ADI was collinear with sex, race, marital status, body mass index, and smoking status. In subgroup analyses, between-group differences in strength of associations of CRC screening with ADI and patient characteristics varied most prominently by race. Conclusion: There may be an unmeasured social context explaining persistent racial differences among factors associated with CRC screening. A combination of census tract and individual-level social determinants may guide population health management for at-risk subpopulations.

Abstract
Preventable differences in colorectal cancer (CRC) mortality across racial/ethnic, economic, geographic, and other groups can be eliminated by assuring equitable access and quality across the care continuum, but few interventions have been demonstrated to do so. Multicomponent strategies designed with a health equity framework may be effective. A health equity framework takes into account social determinants of health, multilevel influences (policy, community, delivery, and individual levels), screening processes, and community engagement. Effective strategies for increasing screening uptake include patient navigation and other interventions for structural barriers, reminders and clinical decision support, and data to continuously track metrics and guide targets for improvement. Community resource gaps should be addressed to assure high-quality services irrespective of racial/ethnic and socioeconomic status. One model combinespopulation-based proactive outreach screening with screening delivery at in-person or virtual points of contact, as well as community engagement. Patient- and provider-based behavioral interventions may be considered for increasing screening demand and delivery. Providing a choice of screening tests is recommended for CRC screening, and access to colonoscopy is required for completion of the CRC screening process.

Abstract
Super enhancers (SEs) are large clusters of adjacent enhancers that drive the expression of genes which regulate cellular identity; SE regions can be enriched with a high density of transcription factors, co-factors, and enhancer-associated epigenetic modifications. Through enhanced activation of their target genes, SEs play an important role in various diseases and conditions, including cancer. Recent studies have shown that SEs not only activate the transcriptional expression of coding genes to directly regulate biological functions, but also drive the transcriptional expression of non-coding RNAs (ncRNAs) to indirectly regulate biological functions. SE-derived ncRNAs play critical roles in tumorigenesis, including malignant proliferation, metastasis, drug resistance, and inflammatory response. Moreover, the abnormal expression of SE-derived ncRNAs is closely related to the clinical and pathological characterization of tumors. In this review, we summarize the functions and roles of SE-derived ncRNAs in tumorigenesis and discuss their prospective applications in tumor therapy. A deeper understanding of the potential mechanism underlying the action of SE-derived ncRNAs in tumorigenesis may provide new strategies for the early diagnosis of tumors and targeted therapy.

Abstract
INTRODUCTION The use of screening can prevent death from colorectal cancer, yet people without regular healthcare visits may not realize the benefits of this preventive intervention. The objective of this study was to determine the effectiveness of a mailed screening invitation or mailed fecal immunochemical test in increasing colorectal cancer screening uptake in veterans without recent primary care encounters. STUDY DESIGN Three-arm pragmatic randomized trial. SETTING/PARTICIPANTS Participants were screening-eligible veterans aged 50-75 years, without a recent primary care visit who accessed medical services at the Corporal Michael J. Crescenz Veteran Affairs Medical Center between January 1, 2017, and July 31, 2017. All data were analyzed from March 1, 2018, to July 31, 2018. INTERVENTION Participants were randomized to (1) usual opportunistic screening during a healthcare visit (n=260), (2) mailed invitation to screen and reminder phone calls (n=261), or (3) mailed fecal immunochemical test outreach plus reminder calls (n=61). MAIN OUTCOME MEASURES The main outcome under investigation was the completion of colorectal cancer screening within 6 months after randomization. RESULTS Of 782 participants in the trial, 53.9% were aged 60-75 years and 59.7% were African American. The screening rate was higher in the mailed fecal immunochemical test group (26.1%) compared with usual care (5.8%) (rate difference=20.3%, 95% CI=14.3%, 26.3%; RR=4.52, 95% CI=2.7, 7.7) or screening invitation (7.7%) (rate difference=18.4%, 95% CI=12.2%, 24.6%; RR=3.4, 95% CI=2.1, 5.4). Screening completion rates were similar between invitation and usual care (rate difference=1.9%, 95% CI= -2.4%, 6.2%; RR=1.3, 95% CI=0.7, 2.5). CONCLUSIONS Mailed fecal immunochemical test screening promotes colorectal cancer screening participation among veterans without a recent primary care encounter. Despite the addition of reminder calls, an invitation letter was no more effective in screening participation than screening during outpatient appointments. TRIAL REGISTRATION This study is registered at clinicaltrials.gov NCT02584998.

Abstract
Background: The Affordable Care Act (ACA) waived deductibles and eliminated coinsurance for colonoscopies for Medicare beneficiaries beginning in January 1, 2011. This study investigated the effect of the ACA’s directive to remove the financial barriers on the receipt of colonoscopies among the elderly insured, who are predominantly covered by Medicare. Methods: Data from the 2008–2016 Behavioral Risk Factor Surveillance System (BRFSS) were used to examine the receipt of colonoscopies in two years prior to the implementation of the ACA (2008 and 2010) and three years after the change (2012, 2014, and 2016). Multivariate logistic regressions were estimated to examine the change in colonoscopy use before and after the introduction of the ACA, adjusting for patient characteristics and availability of health care providers in the geographic region. Results: Of 349,899 eligible elderly insured in the age group 65 to 75 years, 236,275 (67.2%) had received a colonoscopy in the previous ten years. The receipt of colonoscopies increased from 63.5% in pre-ACA years to 69.2% in the post-ACA years (p < 0.001). Compared with the pre-ACA period, the odds ratio of colonoscopy uptake in post-ACA years was 1.15 (95% CI = 1.08–1.22). Conclusions: A statistically significant increase in colonoscopy use was observed in the post-ACA years. However, achieving the target coverage rate of 80% will require additional interventions to encourage higher levels of screenings.

Abstract
Colorectal cancer (CRC) disproportionately affects people from low socioeconomic backgrounds and some racial minorities. Disparities in CRC incidence and outcomes might result from differences in exposure to risk factors such as unhealthy diet and sedentary lifestyle; limited access to risk-reducing behaviors such as chemoprevention, screening, and follow-up of abnormal test results; or lack of access to high-quality treatment resources. These factors operate at the individual, provider, health system, community, and policy levels to perpetuate CRC disparities. However, CRC disparities can be eliminated. Addressing the complex factors that contribute to development and progression of CRC with multicomponent, adaptive interventions, at multiple levels of the care continuum, can reduce gaps in mortality. These might be addressed with a combination of health care and community-based interventions and policy changes that promote healthy behaviors and ensure access to high-quality and effective measures for CRC prevention, diagnosis, and treatment. Improving resources and coordinating efforts in communities where people of low socioeconomic status live and work would increase access to evidence-based interventions. Research is also needed to understand the role and potential mechanisms by which factors in diet, intestinal microbiome, and/or inflammation contribute to differences in colorectal carcinogenesis. Studies of large cohorts with diverse populations are needed to identify epidemiologic and molecular factors that contribute to CRC development in different populations.

Abstract
OBJECTIVE To identify patient, provider, and delivery system-level factors associated with colorectal cancer (CRC) screening and validate findings across multiple data sets. DESIGN A concurrent mixed-methods design using electronic health records, provider survey, and provider interview. SETTING Eight primary care accountable care organization clinics in Nebraska. MEASURES Patients' demographic/social characteristics, health utilization behaviors, and perceptions toward CRC screening; provider demographics and practice patterns; and clinics' delivery systems (eg, reminder system). ANALYSIS Quantitative (frequencies, logistic regression, and t tests) and qualitative analyses (thematic coding). RESULTS At the patient level, being 65 years of age and older (odds ratio [OR] = 1.34, P < .001), being non-Hispanic white (OR = 1.93, P < .001), having insurance (OR = 1.90, P = .01), having an annual physical examination (OR = 2.36, P < .001), and having chronic conditions (OR = 1.65 for 1-2 conditions, P < .001) were associated positively with screening, compared with their counterparts. The top 5 patient-level barriers included discomfort/pain of the procedure (60.3%), finance/cost (57.4%), other priority health issues (39.7%), lack of awareness (36.8%), and health literacy (26.5%). At the provider level, being female (OR = 1.88, P < .001), having medical doctor credentials (OR = 3.05, P < .001), and having a daily patient load less than 15 (OR = 1.50, P = .01) were positively related to CRC screening. None of the delivery system factors were significant except the reminder system. Interview data provided in-depth information on how these factors help or hinder CRC screening. Discrepancies in findings were observed in chronic condition, colonoscopy performed by primary doctors, and the clinic-level system factors. CONCLUSIONS This study informs practitioners and policy makers on the effective multilevel strategies to promote CRC screening in primary care accountable care organization or equivalent settings. Some inconsistent findings between data sources require additional prospective cohort studies to validate those identified factors in question. The strategies may include (1) developing programs targeting relatively younger age groups or racial/ethnic minorities, (2) adapting multilevel/multicomponent interventions to address low demands and access of local population, (3) promoting annual physical examination as a cost-effective strategy, and (4) supporting organizational capacity and infrastructure (eg, IT system) to facilitate implementation of evidence-based interventions.

Abstract
BACKGROUND Socioeconomic status (SES) disparities in colorectal cancer screening are persistent. Lower education and income are both associated with lower screening rates. Both cognitive (e.g., perceived barriers) and affective (e.g., disgust, fear) decision-making constructs are known determinants of colorectal cancer screening behavior. This study tests the hypotheses that SES may be related to decision-making constructs and that this SES-decision-making construct relation may contribute to explaining the SES-screening behavior disparity. METHOD Surveys assessing perceived benefits and barriers to screening, self-efficacy, positive and negative affective associations with colonoscopy, fear of colonoscopy, colorectal cancer knowledge, past screening behavior, and demographics including education and income were completed by 2,015 African American participants ages 50 and older. Both univariable and multivariable relations of SES to decision-making constructs were examined, as were univariable and multivariable models of the indirect effect of SES on screening via decision-making constructs. RESULTS Socioeconomic status was related to both screening compliance and the decision-making constructs. Bootstrap modeling of the indirect effect showed that the total effect of the SES-screening behavior relation included an indirect effect via social cognitive decision-making constructs. CONCLUSION These findings suggest that cognitive and affective decision-making constructs account for at least some of the SES disparities in colorectal cancer screening behavior. As such, more research is needed to explore the intra individual-level influences of disparities in colorectal cancer screening. In addition, work is needed to develop effective intervention approaches to address the relation of SES to decision-making constructs. (PsycINFO Database Record

Abstract
The purpose of this study was to assess family physicians' knowledge, attitudes, and practices toward colorectal cancer (CRC) screening. The population in this cross-sectional study consisted of 290 family physicians working in Samsun, Turkey, contacted between 15 June and 15 July 2015 and agreeing to participate. A questionnaire prepared by the authors on the basis of the relevant literature was applied at face-to-face interviews. The first part of the questionnaire inquired into sociodemographic information, while the second contained questions evaluating family physicians' knowledge, attitudes, and practices toward CRC screening. Physicians completed the questionnaire in approximately 10 min. 65.9 % of the family physicians in the study were men. Mean age of the participants was 43.40 ± 6.54 years, and mean number of years in service was 18.43 ± 6.42. The average number of patients seen by physicians on a daily basis was 51-99. CRC screening was performed by 83.1 % of physicians. The fecal occult blood test (FOBT) was recommended at the correct frequency by 30.7 % of physicians and colonoscopy by 11.7 %. A further 68.6 % of physicians followed no CRC guideline. Only 3.8 % of those reporting using a guideline were able to name it. The great majority of physicians in this study apply CRC screening. However, family physicians lack sufficient information concerning the ages at which screening tests should be started and concluded and how frequently they should be performed. They also do not attach sufficient importance to CRC guidelines. This results in excessive demand for screening tests.

Abstract
INTRODUCTION Recent studies report racial disparities among individuals in organized colorectal cancer (CRC) programs; however, there is a paucity of information on CRC screening utilization by race/ethnicity among newly age-eligible adults in such programs. METHODS This was a retrospective cohort study among Kaiser Permanente Northern California enrollees who turned age 50 years between 2007 and 2012 (N=138,799) and were served by a systemwide outreach and facilitated in-reach screening program based primarily on mailed fecal immunochemical tests to screening-eligible people. Kaplan-Meier and Cox model analyses were used to estimate differences in receipt of CRC screening in 2015-2016. RESULTS Cumulative probabilities of CRC screening within 1 and 2 years of subjects' 50th birthday were 51% and 73%, respectively. Relative to non-Hispanic whites, the likelihood of completing any CRC screening was similar in blacks (hazard ratio, 0.98; 95% CI=0.96, 1.00); 5% lower in Hispanics (hazard ratio, 0.95; 95% CI=0.93, 0.96); and 13% higher in Asians (hazard ratio, 1.13; 95% CI=1.11, 1.15) in adjusted analyses. Fecal immunochemical testing was the most common screening modality, representing 86% of all screening initiations. Blacks and Hispanics had lower receipt of fecal immunochemical testing in adjusted analyses. CONCLUSIONS CRC screening uptake was high among newly screening-eligible adults in an organized CRC screening program, but Hispanics were less likely to initiate screening near age 50 years than non-Hispanic whites, suggesting that cultural and other individual-level barriers not addressed within the program likely contribute. Future studies examining the influences of culturally appropriate and targeted efforts for screening initiation are needed.

Abstract
Yes-associated protein (YAP) is a downstream effector molecule of a newly emerging tumour suppressor pathway called the Hippo pathway. YAP is a transcriptional co-activator and mis-expressed in various cancers, including colorectal cancer (CRC). Accumulating studies show that the high expression of nuclear YAP is linked with tumour progression and decreased survival. Nuclear YAP can interact with other transcription factors to promote cancer cell proliferation, apoptosis, metastasis and maintenance of stemness. Therefore, YAP has the potential to be a tumour biomarker or therapeutic target for CRC. However, recently, a number of studies have supported a contradictory role for YAP as a tumour suppressor, demonstrating inhibition of the tumorigenesis of CRC, involvement in promoting cell apoptosis, and inhibiting the maintenance of intestinal stem cells and inflammatory activity. In these studies, high expression of YAP was highly correlated with worse survival in CRC. In this review, we will comprehensively summarize and analyse these paradoxical reports, and discuss both the oncogenic and tumour suppressor functions of YAP in the differential status of CRC progression. Further investigation into the mechanisms responsible for the dual function of YAP will be of great value in the prevention, early diagnosis, and therapy of CRC.

Abstract
BACKGROUND Colorectal cancer (CRC) is a deadly but largely preventable disease. Screening improves outcomes, but screening rates vary across healthcare coverage models. In the Veterans Health Administration (VA), screening rates are high; however, it is unknown how CRC screening rates compare for Veterans with other types of healthcare coverage. AIMS To determine whether Veterans with Veteran-status-related coverage (VA, military, TRICARE) have higher rates of CRC screening than Veterans with alternate sources of healthcare coverage. METHODS We conducted a cross-sectional analysis of Veterans 50-75 years from the 2014 Behavioral Risk Factor Surveillance System survey. We examined CRC screening rates and screening modalities. We performed multivariable logistic regression to identify the role of coverage type, demographics, and clinical factors on screening status. RESULTS The cohort included 22,138 Veterans. Of these, 76.7% reported up-to-date screening. Colonoscopy was the most common screening modality (83.7%). Screening rates were highest among Veterans with Veteran-status-related coverage (82.3%), as was stool-based screening (10.8%). The adjusted odds of up-to-date screening among Veterans with Veteran-status-related coverage were 83% higher than among Veterans with private coverage (adjusted OR = 1.83, 95% CI = 1.52-2.22). Additional predictors of screening included older age, black race, high income, access to medical care, frequent medical visits, and employed or married status. CONCLUSIONS CRC screening rates were highest among Veterans with Veteran-status-related coverage. High CRC screening rates among US Veterans may be related to system-level characteristics of VA and military care. Insight to these system-level characteristics may inform mechanisms to improve CRC screening in non-VA settings.

Abstract
Socioeconomic status (SES) is often considered a risk factor for health outcomes. SES is typically measured using individual variables of educational attainment, income, housing, and employment variables or a composite of these variables. Approaches to building the composite variable include using equal weights for each variable or estimating the weights with principal components analysis or factor analysis. However, these methods do not consider the relationship between the outcome and the SES variables when constructing the index. In this project, we used weighted quantile sum (WQS) regression to estimate an area-level SES index and its effect in a model of colonoscopy screening adherence in the Minnesota–Wisconsin Metropolitan Statistical Area. We considered several specifications of the SES index including using different spatial scales (e.g., census block group-level, tract-level) for the SES variables. We found a significant positive association (odds ratio = 1.17, 95% CI: 1.15–1.19) between the SES index and colonoscopy adherence in the best fitting model. The model with the best goodness-of-fit included a multi-scale SES index with 10 variables at the block group-level and one at the tract-level, with home ownership, race, and income among the most important variables. Contrary to previous index construction, our results were not consistent with an assumption of equal importance of variables in the SES index when explaining colonoscopy screening adherence. Our approach is applicable in any study where an SES index is considered as a variable in a regression model and the weights for the SES variables are not known in advance.

Abstract
OBJECTIVES Interventions for colorectal cancer (CRC) prevention among black adults are needed. Connections between CRC screening non-adherence and other health risk behaviors may inform intervention development. METHODS Associations between red meat (RM) and fruit and vegetable (FV) consumption, at-risk alcohol use, and CRC ever-screening were examined using adjusted logistic regressions among 520 church-going black adults in Houston, Texas, aged >50. RESULTS In the final adjusted model, being younger, uninsured, eating more RM and engaging in at-risk alcohol use were associated with lower likelihood of CRC ever-screening. CONCLUSIONS Church-based interventions to increase CRC screening among black adults might capitalize on associations with RM consumption and alcohol use behaviors as part of a broader wellness promotion initiative.

Abstract
BACKGROUND Population outreach strategies are increasingly used to improve colorectal cancer (CRC) screening. The influence of primary care on cancer screening in this context is unknown. OBJECTIVE To assess associations between primary care provider (PCP) visits and receipt of CRC screening and colonoscopy after a positive fecal immunochemical (FIT) or fecal occult blood test (FOBT). DESIGN Population-based cohort study. PARTICIPANTS A total of 968,072 patients ages 50-74 years who were not up to date with CRC screening in 2011 in four integrated healthcare systems (three with screening outreach programs using FIT kits) in the Population-Based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium. MEASURES Demographic, clinical, PCP visit, and CRC screening data were obtained from electronic health records and administrative databases. We examined associations between PCP visits in 2011 and receipt of FIT/FOBT, screening colonoscopy, or flexible sigmoidoscopy (CRC screening) in 2012 and follow-up colonoscopy within 3 months of a positive FIT/FOBT in 2012. We used multivariable logistic regression and propensity score models to adjust for confounding. RESULTS Fifty-eight percent of eligible patients completed a CRC screening test in 2012, most by FIT. Those with a greater number of PCP visits had higher rates of CRC screening at all sites. Patients with ≥1 PCP visit had nearly twice the adjusted-odds of CRC screening (OR = 1.88, 95 % CI: 1.86-1.89). Overall, 79.6 % of patients with a positive FIT/FOBT completed colonoscopy within 3 months. Patients with ≥1 PCP visit had 30 % higher adjusted odds of completing colonoscopy after positive FIT/FOBT (OR = 1.30; 95 % CI: 1.22-1.40). CONCLUSIONS Patients with a greater number of PCP visits had higher rates of both incident CRC screening and colonoscopy after positive FIT/FOBT, even in health systems with active population health outreach programs. In this era of virtual care and population outreach, primary care visits remain an important mechanism for engaging patients in cancer screening.

Abstract
Assess whether receipt of tailored printouts generated by the Cancer Risk Intake System (CRIS) – a touch-screen computer program that collects data from patients and generates printouts for patients and physicians – results in more reported patient-provider discussions about colorectal cancer (CRC) risk and screening than receipt of non-tailored information. Cluster-randomized trial, randomized by physician, with data collected via CRIS prior to visit and 2-week follow-up telephone survey among 623 patients. Patients aged 25–75 with upcoming primary-care visits and eligible for, but currently non-adherent to CRC screening guidelines. Patient-reported discussions with providers about CRC risk and testing. Tailored recipients were more likely to report patient-physician discussions about personal and familial risk, stool testing, and colonoscopy (all p < 0.05). Tailored recipients were more likely to report discussions of: chances of getting cancer (+ 10%); family history (+ 15%); stool testing (+ 9%); and colonoscopy (+ 8%) (all p < 0.05). CRIS is a promising strategy for facilitating discussions about testing in primary-care settings. Cancer Risk Intake System (CRIS) intervention is a touch-screen computer program. Patients use CRIS to input CRC risk factor data before primary care appointments. CRIS generates tailored printouts with guideline-based screening recommendations. Our randomized trial compared receipt of CRIS tailored v. non-tailored printouts. CRIS tailored group reported more patient-MD discussion of CRC risk and testing.

Abstract
BACKGROUND Preventive service delivery, including cancer screenings, continues to pose a challenge to quality improvement efforts. Although many studies have focused on person-level characteristics associated with screening, less is known about organizational influences on cancer screening. OBJECTIVES This study aims to understand the association between organizational factors and adherence to cancer screenings. METHODS This study employed a cross-sectional design using organizational-level, patient-level, and area-level data. Dependent variables included breast, cervical, and colorectal cancer screening. Organizational factors describing resource sufficiency were constructed using factor analyses from a survey of 250 Veterans Affairs primary care directors. We conducted random-effects logistic regression analyses, modeling cancer screening as a function of organizational factors, controlling for patient-level and area-level factors. RESULTS Overall, 87% of the patients received mammograms, 92% received cervical and 78% had colorectal screening. Quality improvement orientation increased the odds of cervical [odds ratio (OR): 1.27; 95% confidence interval (CI), 1.03-1.57] and colorectal cancer screening (OR: 1.10; 95% CI, 1.00-1.20). Authority in determining primary care components increased the odds of mammography screening (OR: 1.23; 95% CI, 1.03-1.51). Sufficiency in clinical staffing increased the odds of mammography and cervical cancer screenings. Several patient-level factors, serving as control variables, were associated with achievement of screenings. CONCLUSIONS Resource sufficiency led to increased odds of screening possibly because they promote excellence in patient care by conveying organizational goals and facilitate goal achievement with resources. Complementary to patient-level factors, our findings identified organizational processes associated with better performance, which offer concrete strategies in which facilities can evaluate their capabilities to implement best practices to foster and sustain a culture of quality care.

Abstract
Dominant health care professional discourses on cancer take for granted high levels of individual responsibility in cancer prevention, especially in expectations about preventive screening. At the same time, adhering to screening guidelines can be difficult for lower income and under-insured individuals. Colorectal cancer (CRC) is a prime example. Since the advent of CRC screening, disparities in CRC mortality have widened along lines of income, insurance, and race in the United States. We used a community-engaged research method, Photovoice, to examine how people from medically under-served areas experienced and gave meaning to CRC screening. In our analysis, we first discuss ways in which participants recounted screening as a struggle. Second, we highlight a category that participants suggested was key to successful screening: social connections. Finally, we identify screening as an emotionally laden process that is underpinned by feelings of uncertainty, guilt, fear, and relief. We discuss the importance of these findings to research and practice.

Abstract
OBJECTIVES Although screening for colorectal cancer (CRC) is recommended for all adults aged 50 to 75 years in the United States, there are racial and ethnic disparities in who receives screening. Individuals lacking appropriate CRC screening cite various reasons for nonadherence, including lack of provider recommendation for screening. The purpose of this study is to evaluate the association between patient race and lack of provider recommendation for CRC screening as the primary reason for screening nonadherence. METHODS We conducted a cross-sectional observational study of individuals aged 50 to 75 years from the 2009 California Health Interview Survey who reported nonadherence to 2008 United States Preventive Service Task Force CRC screening guidelines. The outcome was self-report that the main reason for not undergoing CRC screening was lack of a physician recommendation ("non-recommendation") for screening. We performed logistic regression to determine significant predictors of non-recommendation, with particular attention to the role of race. RESULTS The study cohort included 5,793 unscreened subjects. Of the subjects, 19.1% reported that lack of a provider recommendation was the main reason for CRC nonscreening. African Americans (adjusted odds ratio (adj. OR) 1.46, 95% confidence interval (CI) 1.03-2.05) and English-speaking Asians (adj. OR 1.65, 95% CI 1.24-2.20) were more likely than whites to report physician non-recommendation as the main reason for lack of screening. Asian non-English speakers, however, were less likely to report physician non-recommendation (adj. OR 0.31, 95% CI 0.11-0.91). CONCLUSION Racial minorities are less likely than whites to receive a physician recommendation for CRC screening. Future research should evaluate why race appears to influence provider recommendations to pursue CRC screening; this is an important step to reduce disparities in CRC screening and lessen the burden of CRC in the United States.

Abstract
Colorectal cancer (CRC) is a complex disease that develops as a consequence of both genetic and environmental risk factors. A small proportion (3-5%) of cases arise from hereditary syndromes predisposing to early onset CRC as a result of mutations in over a dozen well defined genes. In contrast, CRC is predominantly a late onset 'sporadic' disease, developing in individuals with no obvious hereditary syndrome. In recent years, genome wide association studies have discovered that over 40 genetic regions are associated with weak effects on sporadic CRC, and it has been estimated that increasingly large genome wide scans will identify many additional novel genetic regions. Subsequent experimental validations have identified the causally related variant(s) in a limited number of these genetic regions. Further biological insight could be obtained through ethnically diverse study populations, larger genetic sequencing studies and development of higher throughput functional experiments. Along with inherited variation, integration of the tumour genome may shed light on the carcinogenic processes in CRC. In addition to summarising the genetic architecture of CRC, this review discusses genetic factors that modify environmental predictors of CRC, as well as examples of how genetic insight has improved clinical surveillance, prevention and treatment strategies. In summary, substantial progress has been made in uncovering the genetic architecture of CRC, and continued research efforts are expected to identify additional genetic risk factors that further our biological understanding of this disease. Subsequently these new insights will lead to improved treatment and prevention of colorectal cancer.

Patient navigation to increase colorectal cancer screening among Latino Medicare enrollees: a randomized controlled trial. Cancer Causes Control 2015; 26:1351-9. [PMID: 26109462 PMCID: PMC5215648 DOI: 10.1007/s10552-015-0620-6] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2014] [Accepted: 06/12/2015] [Indexed: 02/06/2023]
Abstract
PURPOSE Latino Medicare enrollees report suboptimal rates of colorectal cancer screening (CRCS) despite Medicare policies designed to improve CRCS access for older persons. Patient navigation (PN) may address many underlying barriers to CRCS, yet little is known about the effectiveness of PN to increase CRCS adherence among Latino Medicare enrollees. METHODS Using a randomized controlled trial study design, we evaluated tailored PN delivered outside of primary care settings as an intervention to increase CRCS adherence in this population. Intervention participants (n = 135) received tailored PN services which included education, counseling, and logistical support administered in their language of choice. Comparison participants (n = 168) received mailed cancer education materials. We compared CRCS rates between interventions and used multivariable logistic regression to assess the odds of CRCS adherence for PN versus comparison groups after adjusting for covariates of interest. RESULTS More navigated than non-navigated participants became CRCS adherent during the study period (43.7 vs. 32.1%, p = 0.04). The odds of CRCS adherence were significantly higher for PN relative to comparison participants before and after adjusting for covariates (unadjusted OR 1.64, p = 0.04; adjusted OR 1.82, p = 0.02). Higher CRCS adherence rates were observed primarily in the uptake of endoscopic screening methods. CONCLUSION This study demonstrates that PN delivered outside of the primary care environment is modestly effective in increasing CRCS adherence among Latino Medicare enrollees. This intervention strategy should be further evaluated as a complement to primary care-based PN and other care coordination strategies to increase adherence with CRCS and other evidence-based screenings among older Latinos.

How many individuals will need to be screened to increase colorectal cancer screening prevalence to 80% by 2018? Cancer 2015; 121:4258-65. [PMID: 26308967 DOI: 10.1002/cncr.29659] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2015] [Revised: 07/20/2015] [Accepted: 07/21/2015] [Indexed: 11/09/2022]
Abstract
BACKGROUND A recent study estimates that 277,000 colorectal cancer (CRC) cases and 203,000 CRC deaths will be averted between 2013 and 2030 if the National Colorectal Cancer Roundtable goal of increasing CRC screening prevalence to 80% by 2018 is reached. However, the number of individuals who need to be screened (NNS) to achieve this goal is unknown. In this communication, the authors estimate the NNS to achieve 80% by 2018 nationwide and by state. METHODS The authors estimated the NNS by subtracting adults aged 50 to 75 years who would need to be screened to achieve an 80% CRC screening prevalence from the number who are currently guideline-compliant from population estimates for this age group. The 2013 National Health Interview Survey and the 2012 Behavioral Risk Factor Surveillance System were used to estimate CRC screening prevalence and data from the US Census Bureau were used to estimate population projections. The NNS were age-standardized and sex-standardized. RESULTS Nationwide, 24.39 million individuals (95% confidence interval, 24.37-24.41 million) aged 50 to 75 years will need to be screened to achieve 80% by 2018. By state, the NNS ranged from 45,400 in Vermont to 2.72 million in California. The majority of individuals who need to be screened are aged 50 to 64 years and the largest subgroup is privately insured. CONCLUSIONS The authors estimated that at least 24.4 million additional individuals in the United States will need to be screened to achieve the National Colorectal Cancer Roundtable goal of increasing CRC screening prevalence to 80% by 2018. To reach this goal, improving facilitators of CRC screening, including physician recommendation and patient awareness, is needed.

Abstract
BACKGROUND Although colorectal cancer death rates in the United States have declined by half since 1970, large geographic disparities persist. Spatial identification of high-risk areas can facilitate targeted screening interventions to close this gap. METHODS We used the Getis-Ord Gi* statistic within ArcGIS to identify contemporary colorectal cancer "hotspots" (spatial clusters of counties with high rates) based on county-level mortality data from the national vital statistics system. Hotspots were compared with the remaining aggregated counties (non-hotspot United States) by plotting trends from 1970 to 2011 and calculating rate ratios (RR). Trends were quantified using joinpoint regression. RESULTS Spatial mapping identified three distinct hotspots in the contemporary United States where colorectal cancer death rates were elevated. The highest rates were in the largest hotspot, which encompassed 94 counties in the Lower Mississippi Delta [Arkansas (17), Illinois (16), Kentucky (3), Louisiana (6), Mississippi (27), Missouri (15), and Tennessee (10)]. During 2009 to 2011, rates here were 40% higher than the non-hotspot United States [RR, 1.40; 95% confidence interval (CI), 1.34-1.46], despite being 18% lower during 1970 to 1972 (RR, 0.82; 95% CI, 0.78-0.86). The elevated risk was similar in blacks and whites. Notably, rates among black men in the Delta increased steadily by 3.5% per year from 1970 to 1990, and have since remained unchanged. Rates in hotspots in west central Appalachia and eastern Virginia/North Carolina were 18% and 9% higher, respectively, than the non-hotspot United States during 2009 to 2011. CONCLUSIONS Advanced spatial analysis revealed large pockets of the United States with excessive colorectal cancer death rates. IMPACT These well-defined areas warrant prioritized screening intervention.

Cancer 2015; 121:3272-80. [PMID: 26042576 DOI: 10.1002/cncr.29494] [Citation(s) in RCA: 79] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2015] [Revised: 04/20/2015] [Accepted: 05/07/2015] [Indexed: 11/06/2022]
Abstract
BACKGROUND The aim of the cost-sharing provision of the Patient Protection and Affordable Care Act (ACA) was to reduce financial barriers for preventive services, including screening for colorectal cancer (CRC) and breast cancer (BC) among privately and Medicare-insured individuals. Whether the provision has affected CRC and BC screening prevalence is unknown. The current study investigated whether CRC and BC screening prevalence among privately and Medicare-insured adults by socioeconomic status (SES) changed before and after the ACA. METHODS Data obtained from the National Health Interview Survey pertaining to privately and Medicare-insured adults from 2008 (before the ACA) and 2013 (after the ACA) were used. There were 15,786 adults aged 50 to 75 years in the CRC screening analysis and 14,530 women aged ≥40 years in the BC screening analysis. Changes in guideline-recommended screening between 2008 and 2013 by SES were expressed as the prevalence difference (PD) and 95% confidence interval (95% CI) adjusted for demographics, insurance, income, education, body mass index, and having a usual provider. RESULTS Overall, CRC screening prevalence increased from 57.3% to 61.2% between 2008 and 2013 (P<.001). Adjusted CRC screening prevalence during the corresponding period increased in low-income (PD, 5.9; 95% CI, 1.8 to 10.2), least-educated (PD, 7.2; 95% CI, 0.9 to 13.5), and Medicare-insured (PD, 6.2; 95% CI, 1.7 to 10.7) individuals, but not in high-income, most-educated, and privately insured respondents. BC screening remained unchanged overall (70.5% in 2008 vs 70.2% in 2013) and in the low SES groups. CONCLUSIONS Increases in CRC screening prevalence between 2008 and 2013 were confined to respondents with low SES. These findings may in part reflect the ACA's removal of financial barriers.

Abstract
Under the 1997 Balanced Budget Act, Medicare expanded coverage of colonoscopy and prostate-specific antigen tests from diagnostic and surveillance tests to preventive screenings. The preventive tests now are covered with no deductibles or copayments. Reducing out-of-pocket costs increases premiums, resulting in a subsidy to beneficiaries who use the service by nonusers, and by taxpayers who shoulder the bulk of Medicare's costs. Using Medicare fee-for-service claims and the Medicare Current Beneficiary Survey, we estimate the behavioral and financial consequences of these Balanced Budget Act coverage expansions. We find that fee-for-service Medicare-covered colonoscopies increased by 3.5 percentage points after the coverage expansion, and prostate-specific antigen tests increased by 6.8 percentage points. Beneficiaries with lower incomes, less education, and those lacking a usual source of care or supplemental insurance were less likely to use these tests. Therefore, they generally received much smaller net benefits from the coverage of colonoscopies than more advantaged beneficiaries.

Abstract
BACKGROUND Repeated qualitative fecal immunochemical test (qlFIT) is a clinical strategy widely used to detect lower gastrointestinal lesions, but its diagnostic power has not been assessed in opportunistic screening for colorectal neoplasia. OBJECTIVE This study aimed to determine the performance of three-sample qlFIT in screening for colorectal cancer and its precursors in high-risk participants. METHODS 513 gastrointestinal outpatients yielded three qlFITs before a standard colonoscopy. We evaluated the diagnostic value of one, two, and three positive qlFITs serving as the positivity threshold. The risk factors of colorectal neoplasia to yield positive qlFITs were also determined. RESULTS 52 patients were diagnosed with colorectal cancer and 70 with advanced adenomatous polyp. For colorectal cancer, the sensitivity and specificity of one positive qlFIT were 90.4% and 53.8%, of two were 80.8% and 75.1%, and of three were 53.9% and 88.5%, respectively. For advanced adenomatous polyp, the sensitivity and specificity of one positive qlFIT were 81.4% and 54.2%, of two were 50.0% and 72.5%, and of three were 28.6% and 86.2%. Left-sided location (OR 2.50, 95%CI 1.26-4.95) and advanced histology of tumors (OR 3.08, 95%CI 1.58-6.01) were independently associated with positive qlFITs. CONCLUSIONS Three-sample qlFIT is a reasonably good method to detect colorectal neoplasia in high-risk population. Tumors in the left side or with advanced pathological features are more likely to produce positive qlFITs.

Abstract
BACKGROUND The utility of hyperbaric oxygen therapy (HBOT) in the treatment of necrotizing soft tissue infections (NSTIs) has not been proved. Previous studies have been subject to substantial selection bias because HBOT is not available universally at all medical centers, and there is often considerable delay associated with its initiation. We examined the utility of HBOT for the treatment of NSTI in the modern era by isolating centers that have their own HBOT facilities. METHODS We queried all centers in the University Health Consortium (UHC) database from 2008 to 2010 that have their own HBOT facilities (n=14). Cases of NSTI were identified by International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes, which included Fournier gangrene (608.83), necrotizing fasciitis (728.86), and gas gangrene (040.0). Status of HBOT was identified by the presence (HBOT) or absence (control) of ICD-9 procedure code 93.95. Our cohort was risk-stratified and matched by UHC's validated severity of illness (SOI) score. Comparisons were then made using univariate tests of association and multivariable logistic regression. RESULTS There were 1,583 NSTI cases at the 14 HBOT-capable centers. 117 (7%) cases were treated with HBOT. Univariate analysis showed that there was no difference between HBOT and control groups in hospital length of stay, direct cost, complications, and mortality across the three less severe SOI classes (minor, moderate, and major). However, for extreme SOI the HBOT group had fewer complications (45% vs. 66%; p<0.01) and fewer deaths (4% vs. 23%; p<0.01). Multivariable analysis showed that patients who did not receive HBOT were less likely to survive their index hospitalization (odds ratio, 10.6; 95% CI 5.2-25.1). CONCLUSION At HBOT-capable centers, receiving HBOT was associated with a significant survival benefit. Use of HBOT in conjunction with current practices for the treatment of NSTI can be both a cost-effective and life-saving therapy, in particular for the sickest patients.

Abstract
Annual fecal occult blood testing (FOBT) has the potential to reduce colorectal cancer mortality, but in practice it is challenging to complete FOBT every year. Repeat FOBT adherence may be especially low in community health center (CHC) settings, where many patients face barriers to annual FOBT completion. We conducted a retrospective cohort analysis to investigate adherence to annual FOBT in an urban CHC network that serves a predominantly Spanish-speaking, uninsured adult patient population. This study used data from the two-year period between January 2010 and December 2011, and included adults aged 50-74 who completed a screening FOBT with a negative result during the first 6 months of 2010. We examined whether each patient completed a second FOBT between 9 and 18 months after the initial negative FOBT, and tested whether repeat FOBT adherence was associated with patient characteristics or the number of clinic visits after the initial negative FOBT. Only 69 of 281 included patients completed repeat FOBT (24.6 % adherence), and none of 62 patients (0 %) with 0 clinic visits completed repeat FOBT. We detected no significant differences in adherence by age, sex, preferred language, insurance status, or number of chronic conditions. In multivariable regression, the adjusted relative risk of repeat FOBT was 1.66 (95 % CI 1.09-2.54; p = 0.02) among patients with 3 or more clinic visits (referent: patients with 1-2 visits). The observed low rate of adherence greatly diminishes the effectiveness of FOBT in reducing CRC mortality. Findings demonstrate the need for systems-based interventions that increase adherence without requiring face-to-face encounters.

Abstract
BACKGROUND Prior studies have shown racial/ethnic disparities in colorectal cancer (CRC) screening but have not provided a full national picture of disparities across all major racial/ethnic groups. PURPOSE To provide a more complete, up-to-date picture of racial/ethnic disparities in CRC screening and contributing socioeconomic and access barriers. METHODS Behavioral Risk Factor Surveillance System data from 2010 were analyzed in 2013. Hispanic/Latino participants were stratified by preferred language (Hispanic-English versus Hispanic-Spanish). Non-Hispanics were categorized as White, Black, Asian, Native Hawaiian/Pacific Islander, or American Indian/Alaska Native. Sequential regression models estimated adjusted relative risks (RRs) and the degree to which SES and access to care explained disparities. RESULTS Overall, 59.6% reported being up-to-date on CRC screening. Self-reported CRC screening was highest in the White (62.0%) racial/ethnic group; followed by Black (59.0%); Native Hawaiian/Pacific Islander (54.6%); Hispanic-English (52.5%); American Indian/Alaska Native (49.5%); Asian (47.2%); and Hispanic-Spanish (30.6%) groups. Adjustment for SES and access partially explained disparities between Whites and Hispanic-Spanish (final relative risk [RR]=0.76, 95% CI=0.69, 0.83); Hispanic-English (RR=0.94, 95% CI=0.91, 0.98); and American Indian/Alaska Native (RR=0.91, 95% CI=0.85, 0.97) groups. The RR of screening among Asians was unchanged after adjustment for SES and access (0.78, p<0.001). After full adjustment, screening rates were not significantly different among Whites, Blacks, or Native Hawaiian/Pacific Islanders. CONCLUSIONS Large racial/ethnic disparities in CRC screening persist, including substantial differences between English-speaking versus Spanish-speaking Hispanics. Disparities are only partially explained by SES and access to care. Future studies should explore the low rate of screening among Asians and how it varies by racial/ethnic subgroup and language.

Abstract
OBJECTIVE To examine whether having a primary care physician (PCP) is associated with reduced ethnic disparities for colorectal cancer (CRC) screening and whether clustering of minorities within PCPs contributes to the disparities. DATA SOURCES/STUDY SETTING Retrospective cohort study of Medicare beneficiaries age 66-75 in 2009 in Texas. STUDY DESIGN The percentage of beneficiaries up to date in CRC screening in 2009 was stratified by race/ethnicity. Multilevel models were used to study the effect of having a PCP and PCP characteristics on the racial and ethnic disparities on CRC screening. DATA COLLECTION/EXTRACTION METHODS Medicare data from 2000 to 2009 were used to assess prior CRC screening. PRINCIPAL FINDINGS Odds of undergoing CRC screening were more than twice as high in patients with a PCP (OR = 2.05, 95 percent CI 2.03-2.07). After accounting for clustering and PCP characteristics, the black-white disparity in CRC screening rates almost disappears and the Hispanic-white disparity decreases substantially. CONCLUSIONS Ethnic disparities in CRC screening in the elderly are mostly explained by decreased access to PCPs and by clustering of minorities within PCPs less likely to screen any of their patients.

Abstract
BACKGROUND On January 1, 2005, Medicare began covering a "Welcome to Medicare" visit (WMV) for new enrollees with fee-for-service (FFS) Medicare (Parts A and B). The new benefit was expected to increase demand for mammography and Pap tests among women transitioning onto Medicare. This study examined whether Medicare's coverage of a WMV influenced the use of mammography and Pap tests among women aged 65 and 66 years with FFS Medicare. METHODS Medicare Current Beneficiary Survey (MCBS) data from 2001 to 2007 were linked with Medicare claims. Utilization rates for preventive visits, mammography, and Pap tests were measured among women entering Medicare. Multivariate logistic regressions were estimated to quantify the effects of the new Medicare benefit on the use of these screening tests, controlling for patient characteristics. RESULTS Regression-adjusted mammography and Pap test rates did not increase after WMV coverage was introduced. The 2005 reform had nonsignificant trivial effects on the use of both tests, most likely because few of the women who were eligible for a WMV took advantage of it. CONCLUSIONS Medicare coverage of a WMV had no impact on mammography screenings or Pap tests among women who were eligible for the benefit.

Abstract
INTRODUCTION Lack of adherence to appointments wastes resources and portends a poorer outcome for patients. The authors sought to determine whether the type of scheduled endoscopic procedures affect compliance. METHODS The authors reviewed the final endoscopy schedule from January 2010 to August 2010 in an inner city teaching hospital that serves a predominantly African American population. The final schedule only includes patients who did not cancel, reschedule or notify the facility of their inability to adhere to their care plan up to 24 hours before their procedures. All patients had face to face consultation with gastroenterologists or surgeons before scheduling. The authors identified patients who did not show up for their procedures. They used Poisson regression models to calculate relative risks (RR) and 95% confidence intervals (CI). RESULTS Of 2183 patients who were scheduled for outpatient endoscopy, 400 (18.3%) patients were scheduled for Esophago-gastro-duodenoscopy (EGD), 1,335 (61.2%) for colonoscopy and 448 (20.5%) for both EGD and colonoscopy. The rate of noncompliance was 17.5%, 22.8% and 22.1%, respectively. When compared with those scheduled for only EGD, patients scheduled for colonoscopy alone (RR = 1.47; 95% CI: 1.13-1.92) and patients scheduled for both EGD and colonoscopy (RR = 1.36; 95% CI: 1.01-1.84) were less likely to show up for their procedures. CONCLUSIONS This study suggests a high rate of noncompliance with scheduled out-patient endoscopy, particularly for colonoscopy. Because this may be a contributing factor to colorectal cancer disparities, increased community outreach on colorectal cancer education is needed and may help to reduce noncompliance.

Abstract
OBJECTIVES To compare completion rates of colorectal cancer screening tests within a health maintenance organization before and after widespread adoption of the fecal immunochemical test (FIT). STUDY DESIGN Retrospective cohort study. METHODS Using electronic medical records of 113,901 patients eligible for colorectal cancer screening, we examined test completion during 2 successive time periods among those who received an automated screening outreach call. The time periods were: 1) the "guaiac fecal occult blood test (gFOBT) era," a 15-month period during which only gFOBT was routinely offered, and 2) a 9-month "FIT era," when only a new FIT was routinely offered. In addition to analyzing completion rates, we analyzed the impact of practice-level variables and patient-level variables on overall screening completion during the 2 different observation periods. RESULTS The change from gFOBT to FIT in an integrated care delivery system increased the likelihood of screening completion by 7.7% overall, and the likelihood of screening with a fecal test by 8.9%. The greatest gains in screening completion using FIT were among women and elderly patients. Completion of FIT was not as strongly associated with medical office visits or with having a primary care provider as was screening with gFOBT. CONCLUSIONS Adoption of FIT within an integrated care system increased completion of colon cancer screening tests within a 9-month assessment period, compared with a previous 15-month gFOBT era. Higher completion rates of the FIT may allow for more effective dissemination of programs to increase colorectal cancer screening through centralized outreach programs.

Neighborhood socioeconomic status and use of colonoscopy in an insured population--a retrospective cohort study. PLoS One 2012; 7:e36392. [PMID: 22567154 PMCID: PMC3342210 DOI: 10.1371/journal.pone.0036392] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2011] [Accepted: 04/05/2012] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Low-socioeconomic status (SES) is associated with a higher colorectal cancer (CRC) incidence and mortality. Screening with colonoscopy, the most commonly used test in the US, has been shown to reduce the risk of death from CRC. This study examined if, among insured persons receiving care in integrated healthcare delivery systems, differences exist in colonoscopy use according to neighborhood SES. METHODS We assembled a retrospective cohort of 100,566 men and women, 50-74 years old, who had been enrolled in one of three US health plans for ≥1 year on January 1, 2000. Subjects were followed until the date of first colonoscopy, date of disenrollment from the health plan, or December 31, 2007, whichever occurred first. We obtained data on colonoscopy use from administrative records. We defined screening colonoscopy as an examination that was not preceded by gastrointestinal conditions in the prior 6-month period. Neighborhood SES was measured using the percentage of households in each subject's census-tract with an income below 1999 federal poverty levels based on 2000 US census data. Analyses, adjusted for demographics and comorbidity index, were performed using Weibull regression models. RESULTS The average age of the cohort was 60 years and 52.7% were female. During 449,738 person-years of follow-up, fewer subjects in the lowest SES quartile (Q1) compared to the highest quartile (Q4) had any colonoscopy (26.7% vs. 37.1%) or a screening colonoscopy (7.6% vs. 13.3%). In regression analyses, compared to Q4, subjects in Q1 were 16% (adjusted HR = 0.84, 95% CI: 0.80-0.88) less likely to undergo any colonoscopy and 30%(adjusted HR = 0.70, CI: 0.65-0.75) less likely to undergo a screening colonoscopy. CONCLUSION People in lower-SES neighborhoods are less likely to undergo a colonoscopy, even among insured subjects receiving care in integrated healthcare systems. Removing health insurance barriers alone is unlikely to eliminate disparities in colonoscopy use.

Abstract
PURPOSE Cancer disparities among racial and ethnic groups are major public health concerns. Our objective was to examine the impact of socioeconomic status (SES) on survival of colon cancer patients within major racial and ethnic groups. METHODS Patients with colon adenocarcinoma from Los Angeles County (LAC) were assessed. SES was utilized as an indicator of healthcare access and categorized by tertiles (high, middle, and low). Patient characteristics were compared and survival analyses were performed. RESULTS In our heterogeneous LAC cohort, we confirmed survival disparities. Asians had the best survival followed by Hispanics, whites, and blacks. For each stage of disease, Asians and Hispanics had better outcomes than whites and blacks. Then, we evaluated the impact of SES on survival within each racial and ethnic group. We observed significantly longer survival for high SES patients compared to middle and low SES patients for all racial/ethnic groups. CONCLUSIONS While disparities across racial/ethnic groups are well-documented, our study is the first to identify socioeconomic disparities in survival for patients within the same group. These novel findings demonstrate the complex role of SES on race and ethnicity and identify the need to improve healthcare access even within select populations.

Abstract
BACKGROUND The benefit of screening for decreasing the risk of death from colorectal cancer (CRC) has been shown, yet many patients in primary care are still not undergoing screening according to guidelines. There are known variations in delivery of preventive health care services among primary care physicians. This study compared self-reported CRC screening rates and patient awareness of the need for CRC screening of patients receiving care from family medicine (FPs) vs. internal medicine (internists) physicians. METHODS Nationally representative sample of non-institutionalized beneficiaries who received medical care from FPs or internists in 2006 (using Medicare Current Beneficiary Survey). The main outcome was the percentage of patients screened in 2007. We also examined the percentage of patients offered screening. RESULTS Patients of FPs, compared to those of internists, were less likely to have received an FOBT kit or undergone home FOBT, even after accounting for patients' characteristics. Compared to internists, FPs' patients were more likely to have heard of colonoscopy, but were less likely to receive a screening colonoscopy recommendation (18% vs. 27%), or undergo a colonoscopy (43% vs. 46%, adjusted odds ratios [AOR], 95% confidence interval [CI]-- 0.65, 0.51-0.81) or any CRC screening (52% vs. 60%, AOR, CI--0.80, 0.68-0.94). Among subgroups examined, higher income beneficiaries receiving care from internists had the highest screening rate (68%), while disabled beneficiaries receiving care from FPs had the lowest screening rate (34%). CONCLUSION Patients cared for by FPs had a lower rate of screening compared to those cared for by internists, despite equal or higher levels of awareness; a difference that remained statistically significant after accounting for socioeconomic status and access to healthcare. Both groups of patients remained below the national goal of 70 percent.

Abstract
BACKGROUND National surveys have reported declines in rates of home-based fecal occult blood test (FOBT) screening for colorectal cancer (CRC) in the last decade. However, socioeconomic status (SES) and racial/ethnic differences in FOBT trends and their changes relative to endoscopic CRC screening have not been evaluated. METHODS Data on adults ages 50 to 64 years from the 2000, 2005, and 2008 National Health Interview Surveys were used. Weighted analyses and multivariate logistic regression were used to study trends in the use of FOBT and endoscopic CRC screening during this period. RESULTS Between 2000 and 2008, significant declines in FOBT prevalence occurred in higher SES groups, but not in lower SES groups (uninsured and publicly insured, those without a usual source of care, lower educated, lower income, and immigrants to the United States) or Hispanics. Endoscopic CRC screening during the period studied consistently increased in all higher SES subgroups. In contrast, few lower SES subgroups (publicly insured, lower educated, near poor individuals, long-term immigrants) and Hispanics experienced increases in CRC endoscopic screening, and these increases were smaller than those observed in higher SES subgroups. CONCLUSIONS Socially and economically disadvantaged groups experienced little or no change in FOBT prevalence, and few of these groups experienced contemporaneous increases in CRC endoscopic screening. These trends suggest the continued availability and acceptance of FOBT in these groups. If national CRC screening goals are to be achieved in populations with lower access to colonoscopy, then annual high-sensitivity FOBT should be promoted as an immediately accessible and viable alternative.

Abstract
PURPOSE Since the early 1980s, colorectal cancer (CRC) mortality rates for whites and blacks in the United States have been diverging as a result of earlier and larger reductions in death rates for whites. We examined whether this mortality pattern varies by stage at diagnosis. METHODS The Incidence-Based Mortality database of the Surveillance, Epidemiology, and End Results (SEER) Program was used to examine data from the nine original SEER regions. Our main outcome measures were changes in stage-specific mortality rates by race. RESULTS From 1985 to 1987 to 2006 to 2008, CRC mortality rates decreased for each stage in both blacks and whites, but for every stage, the decreases were smaller for blacks, particularly for distant-stage disease. For localized stage, mortality rates decreased 30.3% in whites compared with 13.2% in blacks; for regional stage, declines were 48.5% in whites compared with 34.0% in blacks; and for distant stage, declines were 32.6% in whites compared with 4.6% in blacks. As a result, the black-white rate ratios increased from 1.17 (95% CI, 0.98 to 1.39) to 1.41 (95% CI, 1.21 to 1.63) for localized disease, from 1.03 (95% CI, 0.93 to 1.14) to 1.30 (95% CI, 1.17 to 1.44) for regional disease, and from 1.21 (95% CI, 1.10 to 1.34) to 1.72 (95% CI, 1.58 to 1.86) for distant-stage disease. In absolute terms, the disparity in distant-stage mortality rates accounted for approximately 60% of the overall black-white mortality disparity. CONCLUSION The black-white disparities in CRC mortality increased for each stage of the disease, but the overall disparity in overall mortality was largely driven by trends for late-stage disease. Concerted efforts to prevent or detect CRC at earlier stages in blacks could improve the worsening black- white disparities.

Abstract
OBJECTIVES To assess barriers to colorectal cancer screening among urban publicly insured women and to evaluate how barriers among underscreened urban women have changed between 2001 and 2007-2008. METHODS Eligible women were selected using Medicaid Managed Care Organization (MMCO) administrative data. MMCO outreach staff interviewed women by phone between October 2007 and February 2008, and assessed their barriers to colorectal cancer screening. We compared the results of these interviews with interviews conducted in 2001 with women in community health center waiting rooms. RESULTS Thirty percent of overdue women had never heard of either colonoscopy or sigmoidoscopy, and 55% had never heard of home fecal occult blood testing (FOBT). Among overdue women who had heard of colonoscopy or sigmoidoscopy, 33% reported misconceptions and 28% reported worry as a barrier. No clinician recommendation was the most commonly reported barrier to home FOBT (44%) and was also reported as a barrier to endoscopy by 22% of women. Between 2001 and 2007-2008, the proportion of women reporting that they had not received a clinician's recommendation for endoscopy or home FOBT increased significantly. CONCLUSIONS A lack of information, no clinician recommendation, misconceptions, and worry persist as barriers to colon cancer screening among this underscreened urban population. An increased focus on clinician recommendation and patient education about stool-based as well as endoscopic screening methods could lead to greater screening compliance.

Abstract
BACKGROUND Early-stage diagnosis of colorectal cancer is associated with high survival rates; screening prevalence, however, remains suboptimal. PURPOSE This study seeks to test the hypothesis that participants receiving telephone-based tailored education or motivational interviewing had higher colorectal cancer screening completion rates compared to usual care. METHODS Primary care patients not adherent with colorectal cancer screening and with no personal or family history of cancer (n = 515) were assigned by block randomization to control (n = 169), tailored education (n = 168), or motivational interview (n = 178). The response rate was 70%; attrition was 24%. RESULTS Highest screening occurred in the tailored education group (23.8%, p < .02); participants had 2.2 times the odds of completing a post-intervention colorectal cancer screening than did the control group (AOR = 2.2, CI = 1.2-4.0). Motivational interviewing was not associated with significant increase in post-intervention screening. CONCLUSIONS Tailored education showed promise as a feasible strategy to increase colorectal cancer screening.

Abstract
OBJECTIVE To determine whether Medicare managed care penetration impacted the diffusion of endoscopy services (sigmoidoscopy, colonoscopy) among the fee-for-service (FFS) Medicare population during 2001-2006. METHODS We model utilization rates for colonoscopy or sigmoidoscopy as impacted by both market supply and demand factors. We use spatial regression to perform ecological analysis of county-area utilization rates over two time intervals (2001-2003, 2004-2006) following Medicare benefits expansion in 2001 to cover colonoscopy for persons of average risk. We examine each technology in separate cross-sectional regressions estimated over early and later periods to assess differential effects on diffusion over time. We discuss selection factors in managed care markets and how failure to control perfectly for market selection might impact our managed care spillover estimates. RESULTS Areas with worse socioeconomic conditions have lower utilization rates, especially for colonoscopy. Holding constant statistically the socioeconomic factors, we find that managed care spillover effects onto FFS Medicare utilization rates are negative for colonoscopy and positive for sigmoidoscopy. The spatial lag estimates are conservative and interpreted as a lower bound on true effects. Our findings suggest that managed care presence fostered persistence of the older technology during a time when it was rapidly being replaced by the newer technology.

Abstract
BACKGROUND Primary medical care may improve colorectal cancer (CRC) outcomes through increased use of CRC screening tests and earlier diagnosis. We examined the association between primary care utilization and CRC screening, stage at diagnosis, CRC mortality, and all-cause mortality. METHODS We conducted a retrospective cohort study of patients, aged 67 to 85 years, diagnosed as having CRC between 1994 and 2005 in the Surveillance, Epidemiology, and End Results-Medicare-linked database. Association of the number of visits to primary care physicians (PCPs) in the 3- to 27-month period before the CRC diagnosis and CRC screening, early-stage diagnosis, CRC mortality, and all-cause mortality were examined using multivariable logistic regression and Cox proportional hazards models. RESULTS The odds of CRC screening and early-stage diagnosis increased with increasing number of PCP visits (P < .001 for trend). Compared with persons having 0 or 1 PCP visit, patients with 5 to 10 visits had increased odds of ever receiving CRC screening at least 3 months before diagnosis (adjusted odds ratio, 2.60; 95% CI, 2.48-2.72) and early-stage diagnosis (1.35; 1.29-1.42). Persons with 5 to 10 visits had 16% lower CRC mortality (adjusted hazard ratio [AHR], 0.84; 95% CI, 0.80-0.88) and 6% lower all-cause mortality (0.94; 0.91-0.97) compared with persons with 0 or 1 visit. CONCLUSIONS Medicare beneficiaries with CRC have better outcomes if they have greater utilization of primary care before diagnosis. Revitalization of primary care in the United States may help strengthen the national efforts to reduce the burden of CRC.

Abstract
Colorectal cancer is an important global health problem. Randomized trials have shown that screening programs can reduce both colorectal cancer incidence and mortality, and guidelines strongly support screening. Nevertheless, screening rates are relatively low and concerted efforts are being made to increase screening uptake. Many guidelines and practitioners have come to view colonoscopy as the optimal screening strategy. Colonoscopy provides both a gold-standard diagnostic test and, with polypectomy, a therapeutic intervention that can prevent cancer. However, from a public-health perspective, emphasizing colonoscopy is problematic. The efficacy of colonoscopy has not been supported with randomized trial data, accuracy is imperfect, procedural quality is variable, complications are not uncommon, endoscopic capacity is limited, procedure costs are high, and many patients prefer alternative tests. Successful screening programs will need to provide a range of screening modalities and ensure that endoscopic resources are used efficiently.

Abstract
BACKGROUND Evaluating trends in colorectal cancer (CRC) screening use is critical for understanding screening implementation, and whether population groups targeted for screening are receiving it, consistent with guidelines. This study examines recent national trends in CRC test use, including among vulnerable populations. METHODS We used the 2000, 2003, 2005, and 2008 National Health Interview Survey to examine national trends in CRC screening use overall and for fecal occult blood test (FOBT), sigmoidoscopy, and colonoscopy. We also assessed trends by race/ethnicity, educational attainment, income, time in the United States, and access to health care. RESULTS During 2000 to 2008, significant declines in FOBT and sigmoidoscopy use and significant increases in colonoscopy use and in the percentages of adults up-to-date with CRC screening occurred overall and for most population subgroups. Subgroups with consistently lower rates of colonoscopy use and being up-to-date included Hispanics; people with minimal education, low income, or no health insurance; recent immigrants; and those with no usual source of care or physician visits in the past year. Among up-to-date adults, there were few subgroup differences in the type of test by which they were up-to-date (i.e., FOBT, sigmoidoscopy, or colonoscopy). CONCLUSIONS Although use of CRC screening and colonoscopy increased among U.S. adults, including those from vulnerable populations, 45% of adults aged 50 to 75-or nearly 35 million people-were not up-to-date with screening in 2008. IMPACT Continued monitoring of CRC screening rates among population subgroups with consistently low utilization is imperative. Improvement in CRC screening rates among all population groups in the United States is still needed.
