Cardiovascular Health and Colorectal Cancer Screening in Black Men: A Cross-Sectional Analysis.

African American/Black (henceforth Black) men face disproportionate risks of morbidity and mortality from both cardiovascular disease (CVD) and colorectal cancer (CRC). The American Heart Association's Life's Simple 7 (LS7) tool was designed to examine predictors of CVD with included behaviors also linked to CRC risk (i.e., smoking status, weight, diet, and physical activity). However, no studies have combined LS7 assessment alongside CRC screening history, which serves as a proxy for assessing CRC risk, in Black men. In this study, Black men aged 45-75 participating in annual community wellness events were screened for 6 of 7 LS7 measures (excluding diet, LS6) and self-reported CRC screening. Analyses conducted using R 4.0.5. revealed that Black men (N = 680), with an average age of 57.3 years (SD = 7.5), reported poor (39.7%), intermediate (34.6%), or ideal (25.7%) LS6 scores with higher scores corresponding to lower risk for CVD. However, for every 1-point increase in LS6 scores (0-6), there was a 26% lower odds of reported CRC screening (p = .001). In the fully adjusted model, men with 4+ ideal LS6 behaviors had a 60% lower odds of self-reported CRC screening compared to those with two ideal LS6 behaviors (p < .001). These findings underscore the need for culturally relevant interventions for Black men across all levels of cardiovascular health (CVH) to increase CRC screening uptake.

S255 Assessing the Impact of a Multi-Component Health System Intervention to Address Low Colorectal Cancer Screening Participation in Patients With a Family History of Colorectal Cancer

Introduction: In the United States, 3-10% of individuals have a family history of colorectal cancer (CRC). Population health strategies to increase CRC screening often exclude these individuals, and interventions to increase screening participation in this high-risk group are rare. We designed and implemented a multi-component health system intervention to increase CRC screening uptake among individuals with a family history of CRC that were excluded from mailed fecal immunochemical test (FIT) outreach in our health system. Methods: The study was performed in a large academic medical center with biannual mailed FIT outreach for individuals at average-risk for CRC. We included patients who did not receive mailed FIT outreach in 2021 due to a family history of CRC. We excluded patients with a personal history of inflammatory bowel disease, colectomy, or CRC. The intervention included both primary care provider (PCP) and patient components. The PCP component was sent via the electronic health record (EHR) and included CRC screening guidelines for patients with a family history of CRC and a pended colonoscopy order for each patient overdue for screening. The patient component was delivered via the EHR patient portal and a mailed letter and included education about familial risk and colonoscopy, and a prompt to schedule a colonoscopy. Preliminary outcomes were measured 2-months post-intervention and were whether: (1) the PCP signed the pended colonoscopy order and (2) the patient scheduled colonoscopy. We used descriptive statistics to describe the study cohort and paired t-tests to compare the study outcomes pre- and post-intervention. The primary outcome of colonoscopy completion will be measured 6 months post-intervention. Results: 152 patients received the intervention. The mean age was 61.3 years (s.d 7.0), 32.9% were male, and 42.1% were non-Hispanic White (Table). Colonoscopy orders increased from 32 (21.1%) to 92 (60.5%) from pre- to post-intervention (p< 0.0001) (Figure). Colonoscopies scheduled increased from 0 to 9 (5.9%) (p=0.002). Conclusion: We designed and evaluated the preliminary results of a health system intervention that aims to increase screening participation among individuals with a family history of CRC. There was a significant increase in both colonoscopies ordered and colonoscopies scheduled. This study demonstrates a successful population health strategy to increase provider and patient intention to screen in this high-risk population.Figure 1.: Screening colonoscopies ordered and screening colonoscopies scheduled pre- intervention versus post- intervention, n= 152 Table 1. - Intervention population characteristics, n= 152 Patient Characteristic Study Population (n=152) Age [years, mean (SD)] 61.3 (7.0) Male Sex [n (%)] 50 (32.9) White Race [n (%)] 72 (47.4) Non-Hispanic Ethnicity [n (%)] 116 (76.3) Private Insurance [n (%)] 149 (98.0) Married [n (%)] 83 (54.6) English Language Preference [n (%)] 147 (96.7) Social Vulnerability Index [median (IQR)] 25.9 (11.8-47.8) Current or Former Tobacco Use Disorder [n (%)] 38 (25.0) Current or Former Alcohol Use Disorder [n (%)] 13 (8.6) Body Mass Index ≥ 25 [n (%)] 100 (66.2) Hemoglobin A1c ≥ 5.7 [n (%)] 75 (52.8) Family Members with Documented CRC [median (IQR)] 1 (1-1) 1st Degree Family Members with Documented CRC [median (IQR)] 1 (1-1) Years since Last PCP Visit [median (IQR)] 1.01 (0.75-1.62) Years since Last GI Visit [median (IQR)] 2.3 (2.5-9.2) Breast Cancer Screening Up-To-Date [n (%)] 47 (47) Cervical Cancer Screening Up-To-Date [n (%)] 61 (83.6)

Interventions to Increase Colorectal Cancer Screening Uptake in Primary Care: A Systematic Review

We systematically reviewed and summarized previous studies that examined facilitators and barriers to implementing interventions to increase CRCS uptake in primary care practice. We searched PubMed, Medline (EBSCO), and CINAHL databases, from the inception of these databases to April 2020. The search strategy combined a set of terms related to facilitators/barriers, intervention implementation, CRCS, and uptake/participation. A priori set inclusion and exclusion criteria were used during both title/abstract screening and full-text screening phases to identify the eligible studies. Quality of the included studies was appraised using quality assessment tools, and data were extracted using a predetermined data extraction tool. We classified facilitators and barriers according to the Consolidated Framework for Implementation Research domains and constructs and identified the common facilitators and barriers looking at how common they were across studies. A total of 12 studies were included in the review. Engagement of the clinic team, leadership team, and partners, clinics' motivation to improve CRCS rates, use of the EMR system, continuous monitoring and feedback system, and having a supportive environment for implementation were the most commonly reported implementation facilitators. Limited time for the clinic team to devote to a new project, challenges in getting accurate, timely data related to CRCS, limited capacity/support to use the EMR system, and disconnect between clinic team members were the most commonly reported implementation barriers. The synthesized findings improve our understanding of facilitators of and barriers to the implementation of interventions to increase CRCS participation in primary care practice, and inform the customized implementation strategies. Many of the included studies had limited use of rigorous implementation science frameworks to guide their implementation and evaluation, which precludes a comprehensive understanding of the implementation factors specific to CRCS interventions in primary care. Future studies assessing the CRCS intervention implementation factors would benefit from the use of implementation science frameworks.

Implementing Strategies at the Workplace Level to Increase Colorectal Cancer Screening Uptake in Argentina: A Controlled Interrupted Time-series Study.

Employee-facing multifaceted worksite cancer screening interventions are a valuable means to increase knowledge and utilization of workers. The controlled ITS showed that colorectal cancer screening mean uptake rates were 16 times higher in the intervened versus the control population during the intervention period, particularly among women aged 50 to 75.

Multilevel Pathways of Colorectal Cancer Screening Among Low-Income Vietnamese Americans: A Structural Equation Modeling Analysis.

Background:Colorectal cancer (CRC) disproportionately affects Vietnamese Americans, especially those with low income and were born outside of the United States. CRC screening tests are crucial for prevention and early detection. Despite the availability of noninvasive, simple-to-conduct tests, CRC screening rates in Asian Americans, particularly Vietnamese Americans, remain suboptimal. The purpose of this study was to evaluate the interplay of multilevel factors – individual, interpersonal, and community – on CRC screening behaviors among low-income Vietnamese Americans with limited English proficiency.Methods:This study is based on the Sociocultural Health Behavior Model, a research-based model that incorporates 6 factors associated with decision-making and health-seeking behaviors that result in health care utilization. Using a community-based participatory research approach, we recruited 801 Vietnamese Americans from community-based organizations. We administered a survey to collect information on sociodemographic characteristics, health-related factors, and CRC screening-related factors. We used structural equation modeling (SEM) to identify direct and indirect predictors of lifetime CRC screening.Results:Bivariate analysis revealed that a greater number of respondents who never screened for CRC reported limited English proficiency, fewer years of US residency, and lower self-efficacy related to CRC screening. The SEM model identified self-efficacy (coefficient = 0.092, P < .01) as the only direct predictor of lifetime CRC screening. Educational attainment (coefficient = 0.13, P < .01) and health beliefs (coefficient = 0.040, P < .001) had a modest significant positive relationship with self-efficacy. Health beliefs (coefficient = 0.13, P < .001) and educational attainment (coefficient = 0.16, P < .01) had significant positive relationships with CRC knowledge.Conclusions:To increase CRC screening uptake in medically underserved Vietnamese American populations, public health interventions should aim to increase community members’ confidence in their abilities to screen for CRC and to navigate associated processes, including screening preparation, discussions with doctors, and emotional complications.

Abstract PR13: Multilevel pathways of colorectal cancer screening among low-income Vietnamese Americans: A structural equation modeling analysis

Abstract Background: Colorectal cancer (CRC) disproportionately affects Vietnamese Americans, especially those of low economic standing and those who were born outside of the US. CRC screening tests are crucial for CRC prevention and early detection. Fecal immunochemical test (FIT) is non-invasive and easier to be done for low-resource settings. Yet screening rates in Vietnamese Americans were suboptimal. The purpose of this community-based study was to evaluate a heuristic model identifying the individual-, interpersonal, and community-level factors contributing to CRC screening among low-income Vietnamese Americans. Methods: This study uses the theoretical framework of the Sociocultural Health Behavior Model (SCHBM), a research-based model that suggests six factors associated with decision-making with health-seeking behaviors that result in health care utilization. For data collection, using the community-based participatory approach, we recruited a total of 801 Vietnamese men and women age 50 or older from community-based organizations. We conducted an assessment among all participants to collect information on their socio-demographic characteristics and health-related factors, as well as CRC screening related factors. We used structural equation modeling to identify direct and indirect predictors of lifetime CRC screening. Results: Bivariate analysis revealed that Vietnamese respondents who were never screened for CRC were significantly more likely to have limited English proficiency, fewer number of years US residency, and lower self-efficacy related to CRC screening. The final SEM model identified self-efficacy (coefficient= 0.092, z=3.00, p&amp;lt;.01) as the only direct predictor of lifetime CRC screening. Educational attainment (coefficient=0.13, z=2.76, p&amp;lt;.01) and health beliefs (coefficient=0.040, z=3.20, p&amp;lt;.001) had a modest significant positive relationship with self-efficacy. Health belief (coefficient=0.13, z=7.68, p&amp;lt;.001) and educational attainment (coefficient=0.16, z=2.59, p&amp;lt;.01) had significant positive relationships with CRC knowledge. Furthermore, educational attainment (coefficient= .13, z = 2.34, p &amp;lt;.01) had a significant positive relationship with the enabling factor, insurance coverage. Conclusions: The tested theoretical model shows promise in predicting lifetime CRC testing among low-income Vietnamese Americans. To increase CRC screening uptake in this medically underserved population, public health intervention should aim to increase community members’ confidence in their abilities to screen for CRC and handling the testing related protocols (preparation, discussion with doctor and handling emotional complications). Culturally sensitive and linguistically competent intervention materials are needed. Implementing community-based strategies like partnering with relevant community-based organizations are important for meeting CRC policy targets. Citation Format: Lin Zhu, Timmy R.

Abstract C124: Interventions for increasing colorectal cancer screening uptake among African-American men: A systematic review

Abstract African-American men have the lowest 5-year survival rate for colorectal cancer (CRC) of any ethnic/racial group in the country, which may be due in part to poor screening rates. Evidenced-based interventions are needed to increase CRC screening (CRCS) uptake among this population, as screening is associated with increased survival. Using Rayyan QCRI, a systematic review was employed to synthesize the evidence from published studies evaluating interventions to increase CRCS uptake among African-American men. Potential studies were retrieved from MEDLINE, CINAHL, EMBASE, and Cochrane CENTRAL resulting in 960 initial results. Articles published before 1998 were excluded, as well as studies that were not explicitly about CRCS uptake, were not in English, did not take place in the U.S., and/or did not include African-American men. Only primary analyses and evaluations of CRCS uptake interventions, as opposed to interventions considering behaviors related to but not directly indicative of CRCS uptake, were considered. After an abstract screening and full-text review was conducted by two blinded team members, 41 publications ranging from 2000 – 2018 made up the final sample. These studies were then coded for study setting, geographic region, theory, intervention type, and limitations. The majority of studies were conducted in either a medical center or church in the southern U.S. Nearly half of the studies did not report a theoretical foundation, yet in those which did, the Health Belief Model, Preventative Health Model, and the Stages of Change Model were the most common. Reflecting recent screening guidelines endorsed by the American Cancer Society, studies had age ranges starting as early as age 45. The most common interventions of 122 types utilized were telephone education (18%), mailed/electronically-sent educational materials (14%), mailed or administered in person CRCS stool-based kits (12%), and patient navigation (11%), and printed materials given to individuals in person (11%). The most effective intervention types were patient navigation and free stool kits, but were limited due to sustainability cost. Such a finding indicates a need for more research to uncover effective interventions that are not cost-prohibitive. Print education materials that were culturally-tailored specifically for African-Americans often performed as well as control interventions (e.g., those utilizing the Centers for Disease Control and Prevention’s Screen for Life Campaign materials). Furthermore, given most of the interventions took place in the south, studies in other regions of the country may uncover different CRC screening uptake patterns, as there may be regional variation in intervention effectiveness among African-American men. A major weakness our review revealed was that only 2 of the 41 studies (5%) solely focused on African-American men, warranting the needed for intervention samples comprised exclusively of African-American men to eliminate CRC screening uptake inequities.

Association between colorectal cancer testing and insurance type: Evidence from the Swiss Health Interview Survey 2012.

Both colonoscopy and fecal occult blood test (FOBT) are commonly used for colorectal cancer (CRC) screening, but colonoscopy costs much more than FOBT. Swiss insurance offers high or low deductibles and choice of basic or private insurance. We hypothesized that high deductibles and basic insurance discourage colonoscopy, but do not change FOBT rates. We determined the proportion of patients tested for CRC in Switzerland (colonoscopy within 10years, FOBT within 2years), and determined associations with health insurance type. We extracted data on 50-75-year-olds from the Swiss Health Interview Surveys of 2012 to determine colonoscopy and FOBT testing rates (n=7335). Multivariate logistic regression models estimated prevalence ratios (PRs) of CRC testing associated with health insurance type (deductible and private insurance), adjusted for socio-demographic factors (age, gender, education, income) and self-rated health. The weighted proportion of individuals tested for CRC within recommended intervals was 39.5%. Testing with colonoscopy was significantly associated with private insurance (PR 1.85, 95% CI: 1.46-2.35) and low deductible (PR 2.00, 95% CI: 1.56-2.57). Testing with FOBT was significantly associated with deductible (PR 1.71, 95%CI:1.09-2.68) but not with private insurance. About 60% of the Swiss population was not current with CRC testing. After adjusting for covariates, private insurance and low deductible was significantly associated with higher prevalence of CRC testing, indicating that waiving the deductible could increase CRC screening uptake and reduce health inequality.

Financial Incentives to Increase Colorectal Cancer Screening Uptake and Decrease Disparities

IMPORTANCEColorectal cancer screening rates are suboptimal, particularly among sociodemographically disadvantaged groups.OBJECTIVETo examine whether guaranteed money or probabilistic lottery financial incentives conditional on completion of colorectal cancer screening increase screening uptake, particularly among groups with lower screening rates.DESIGN, SETTING, AND PARTICIPANTSThis parallel, 3-arm randomized clinical trial was conducted from March 13, 2017, through April 12, 2018, at 21 medical centers in an integrated health care system in western Washington. A total of 838 age-eligible patients overdue for colorectal cancer screening who completed a questionnaire that confirmed eligibility and included sociodemographic and psychosocial questions were enrolled.INTERVENTIONSInterventions were (1) mail only (n = 284; up to 3 mailings that included information on the importance of colorectal cancer screening and screening test choices, a fecal immunochemical test [FIT], and a reminder letter if necessary), (2) mail and monetary (n = 270; mailings plus guaranteed $10 on screening completion), or (3) mail and lottery (n = 284; mailings plus a 1 in 10 chance of receiving $50 on screening completion).MAIN OUTCOMES AND MEASURESThe primary outcome was completion of any colorectal cancer screening within 6 months of randomization. Secondary outcomes were FIT or colonoscopy completion within 6 months of randomization. Intervention effects were compared across sociodemographic subgroups and self-reported psychosocial measures.RESULTSA total of 838 participants (mean [SD] age, 59.7 [7.2] years; 546 [65.2%] female; 433 [52.2%] white race and 101 [12.1%] Hispanic ethnicity) were included in the study. Completion of any colorectal screening was not significantly higher for the mail and monetary group (207 of 270 [76.7%]) or the mail and lottery group (212 of 284 [74.6%]) than for the mail only group (203 of 284 [71.5%]) (P = .11). For FIT completion, interventions had a statistically significant effect (P = .04), with a net increase of 7.7% (95% CI, 0.3%–15.1%) in the mail and monetary group and 7.1% (95% CI, −0.2% to 14.3%) in the mail and lottery group compared with the mail only group. For patients with Medicaid insurance, the net increase compared with mail only in FIT completion for the mail and monetary or the mail and lottery group was 37.7% (95% CI, 11.0%–64.3%) (34.2% for the mail and monetary group and 40.4% for the mail and lottery group) compared with a net increase of only 5.6% (95% CI, −0.9% to 12.2%) among those not Medicaid insured (test for interaction P = .03).CONCLUSIONS AND RELEVANCEFinancial incentives increased FIT uptake but not overall colorectal cancer screening. Financial incentives may decrease screening disparities among some sociodemographically disadvantaged groups.TRIAL REGISTRATIONClinicalTrials.gov identifier:

Promoting Colorectal Cancer Screening in Foreign-Born Chinese-American Women: Does Racial/Ethnic and Language Concordance Matter?

Chinese Americans are one of the fastest-growing and largest Asian-American subgroups. Approximately 70% of Chinese Americans are immigrants with 46% being of limited English proficiency. Despite colorectal cancer (CRC) being the second leading cause of cancer death in Chinese Americans, Chinese Americans have lower CRC screening rates than other Asian subgroups, and only 40% of CRC cases among Chinese Americans are diagnosed early. Furthermore, CRC is the second most common cancer among Chinese American women. Race/ethnicity concordant providers may process culturally specific knowledge, skills, and experience that may facilitate better communication. Although using an interpreter can help to overcome language barriers between providers and patients, it may not achieve the same level of communication as a language concordant provider. The purpose of this study was to test a community education intervention, taking into account the racial/ethnic and language concordance of the presenter, to increase CRC screening uptake among foreign-born Chinese American women. This study used a quasi-experimental design and a convenience sample of 198 foreign-born Chinese-American women. Logistic regression was used to examine the effect of racial/ethnic and language concordance of the presenter on the return of completed FOBT kits for testing. The Chinese/English-speaking presenter had the highest return rate (73%), followed by the White/English-speaking presenter (61%), and the Chinese/Chinese-speaking presenter (48%), and the differences were statistically significant. Post-education intention to screen was also a significant predictor for returning the FOBT kit for testing. The use of an interpreter did not decrease the effectiveness of the educational intervention.

Systematic review of colorectal cancer screening guidelines for average-risk adults: Summarizing the current global recommendations.

AIMTo summarize and compare worldwide colorectal cancer (CRC) screening recommendations in order to identify similarities and disparities.METHODSA systematic literature search was performed using MEDLINE, EMBASE, Scopus, CENTRAL and ISI Web of knowledge identifying all average-risk CRC screening guideline publications within the last ten years and/or position statements published in the last 2 years. In addition, a hand-search of the webpages of National Gastroenterology Society websites, the National Guideline Clearinghouse, the BMJ Clinical Evidence website, Google and Google Scholar was performed.RESULTSFifteen guidelines were identified. Six guidelines were published in North America, four in Europe, four in Asia and one from the World Gastroenterology Organization. The majority of guidelines recommend screening average-risk individuals between ages 50 and 75 using colonoscopy (every 10 years), or flexible sigmoidoscopy (FS, every 5 years) or fecal occult blood test (FOBT, mainly the Fecal Immunochemical Test, annually or biennially). Disparities throughout the different guidelines are found relating to the use of colonoscopy, rank order between test, screening intervals and optimal age ranges for screening.CONCLUSIONAverage risk individuals between 50 and 75 years should undergo CRC screening. Recommendations for optimal surveillance intervals, preferred tests/test cascade as well as the optimal timing when to start and stop screening differ regionally and should be considered for clinical decision making. Furthermore, local resource availability and patient preferences are important to increase CRC screening uptake, as any screening is better than none.

Testing the Effectiveness of a Primary Care Intervention to Improve Uptake of Colorectal Cancer Screening: A Randomized Controlled Trial Protocol.

BackgroundScreening for colorectal cancer (CRC) significantly reduces mortality associated with this disease. In Australia, the National Bowel Cancer Screening Program provides regular fecal occult blood tests (FOBT) for those aged 50 to 74 years, however, participation rates in the program have plateaued at 36%. Given low uptake in the National Bowel Cancer Screening Program, it is necessary to explore alternate methods to increase CRC screening rates. Primary care is a promising adjunct setting to test methods to increase CRC screening participation. Primary care guidelines support the recommendation and provision of CRC screening to primary care patients. Those in the National Bowel Cancer Screening Program target age range frequently present to their primary care provider.ObjectiveThis study tests the effect that a multicomponent primary care–based intervention has on CRC screening uptake when compared to usual care.MethodsPrimary care patients presenting for an appointment with their primary care provider complete a touchscreen survey to determine eligibility for the trial. Those aged 50 to 74 years, at average risk of CRC, with no history of CRC or inflammatory bowel disease, who have not had an FOBT in the past 2 years or a colonoscopy in the past 5 years are eligible to participate in the trial. Trial participants are randomized to the intervention or usual care group by day of attendance at the practice. The intervention consists of provision of an FOBT, printed information sheet, and primary care provider endorsement to complete the FOBT. The usual care group receives no additional care.ResultsThe primary outcome is completion of CRC screening 6 weeks after recruitment. The proportion of patients completing CRC screening will be compared between trial groups using a logistic regression model.ConclusionsCRC screening rates in Australia are suboptimal and interventions to increase screening participation are urgently required. This protocol describes the process of implementing a multicomponent intervention designed to increase CRC screening uptake in a primary care setting.Trial RegistrationAustralian New Zealand Clinical Trials Registry ACTRN12616001299493; https://anzctr.org.au/Trial/Registration/TrialReview.aspx?id=371136&isReview=true (Archived by WebCite at http://www.webcitation.org/6pL0VYIj6).

Colorectal cancer screening in the familial risk population: Is colonoscopy still the strategy of choice?

First-degree relatives of patients with colorectal cancer (CRC) are at high risk of this disease. For this reason, medical organizations and clinical guidelines recommend more intensive screening and surveillance for such first-degree relatives than for the average-risk population. Colonoscopy has been the cornerstone of CRC screening in this setting. Although colonoscopy is the most sensitive technique for the detection of neoplastic lesions (especially non-advanced adenomas), its role is less clear for CRC. In addition, screening colonoscopy has several limitations that may affect the success of a screening campaign, such as poor participant acceptance, the need for skilled endoscopists, participant access to screening colonoscopy, overburdened endoscopy units, potential complications, and procedure-related costs. In addition, recent evidence has cast doubt on the advantage of colonoscopy over other strategies for the detection of advanced neoplastic lesions. Despite being less sensitive in general, other screening methods frequently recommended in the average-risk population may be more acceptable and thus help increase CRC screening uptake. This review discusses recent evidence on the risk of CRC in first-degree relatives, the advantages and disadvantages of each screening technique, participation rates depending on the technique, patient preferences, and barriers to screening.

Acceptability of Physician Directed Academic Detailing to Increase Colorectal Cancer Screening: an Application of the RESPECT Approach.

Background: In developing effective interventions to increase colorectal cancer (CRC) screening in at risk populations, a necessary first requirement is feasibility. This paper describes how the RESPECT approach to health education guided the conceptualization and implementation of physician-directed academic detailing (AD) to increase practice-wide CRC screening uptake. Methods: Physician-directed AD was one intervention component in a large educational randomized controlled trial to increase CRC screening uptake. Study participants, primarily urban minority, were aged 50 or older, insured for CRC screening with no out-of-pocket expense and out of compliance with current screening recommendations. The trial was conducted in the New York City metropolitan area. Participants identified their primary care physician; 564 individuals were recruited, representing 459 physician practices. Two-thirds of the physician practices were randomized to receive AD. The RESPECT approach, modified for AD, comprises: 1) Rapport, 2) Educate, but don’t overwhelm, 3) Start with physicians where they are, 4) Philosophical orientation based on a humanistic approach to education, 5) Engagement of the physician and his/her office staff, 6) Care and show empathy, and 7) Trust. Feasibility was assessed as rate of AD delivery. Results: The AD was delivered to 283 (92.5%) of the 306 practices assigned to receive it; 222/283 (78.4%) delivered to the doctor. Conclusion: The AD was feasible and acceptable to implement across a range of clinical settings. The RESPECT approach offers a framework for tailoring educational efforts, allowing flexibility, as opposed to strict adherence to a highly structured script or a universal approach.

Decisional stage distribution for colorectal cancer screening among diverse, low-income study participants.

Colorectal cancer (CRC) screening uptake among minorities and those with lower incomes is suboptimal. Behavioral interventions specifically tailored to these populations can increase screening rates and save lives. The Precaution Adoption Process Model (PAPM) allows assignment of a decisional stage for adoption of a behavior such as CRC screening. Here, we characterize the PAPM decisional stage distribution among 470 low income, racially and ethnically diverse study participants at intake into a behavioral intervention study designed to increase CRC screening uptake. We staged participants for stool blood test (SBT) and colonoscopy separately and used the highest stage for the two tests as the 'overall' stage for CRC screening. For SBT, sex, language (English versus Spanish) and doctor recommendation were significantly related to PAPM stage for CRC screening. For colonoscopy, language, education level, doctor recommendation and self-efficacy were related to stage. For overall CRC screening stage, all the variables associated with either SBT or colonoscopy, with the exception of language were significant. This study suggests attending to these key variables in designing interventions to promote CRC screening, particularly with respect to medically underserved populations.

Predictors of Low Colorectal Cancer Screening in an Urban Academic Family Practice

Purpose: The primary objective was to describe the specific socio-demographic variables that are associated with colorectal cancer (CRC) under-screening in an urban, inner city population. The secondary objective was to determine the overall proportion of eligible patients who are not appropriately screened. Methods: A retrospective chart review of patients eligible for average-risk CRC screening as per Ontario’s ColonCancerCheck program guidelines was conducted at an academic, inner city family health practice associated with St. Michael’s Hospital in Toronto, Ontario. Simple measures of association, including t-tests and chi-square tests, were used to determine the relationships between screening and demographic characteristics. Based on a type I error rate of 0.05 and an appropriate sample size, the calculated power for this study was 0.82. Results: A total of 200 patients were randomly selected; 54% were male; the majority were non-immigrants (77.5%) and were employed or retired (76.5%). Fifty-five percent of screened patients were up to date as per guidelines; 29.5% and 31% were up to date with a fecal occult blood test or a colonoscopy respectively. Individuals with psychiatric illness (p = 0.0005), with no history of prior cancer screening for other cancers (p = 0.0001), on disability or unemployed (p = 0.0010), or who were younger (p = 0.0062) were significantly less likely to undergo CRC screening. Conclusion: Colorectal cancer screening rates at this academic, urban family practice were very similar to province wide screening rates. Future studies should focus on group specific interventions to increase CRC screening uptake in low CRC screened populations.

Colonoscopy and fecal occult blood test use in Germany: results from a large insurance-based cohort

Colonoscopy and guaiac-based fecal occult blood tests (FOBT) are recommended and offered for colorectal cancer (CRC) screening in Germany. We aimed to explore their utilization in a large insurance-based cohort. Claims data from between 2000 and 2008 were collected for 170493 individuals who were insured by a large health insurance plan in the federal state of Hesse, Germany. The percentages of individuals who had recently utilized CRC screening-related procedures were calculated. Additionally, multiple test use and identification of CRC screening providers were ascertained. Following the inception of the current CRC screening program in 2002, colonoscopy utilization rates varied only slightly and FOBT use decreased in individuals aged ≥50 years. At the end of 2008, the age-standardized percentages of individuals who had undergone colonoscopy within ≤10 years were 23% for men and 26% for women. The proportions of individuals who had used FOBT within ≤1 year were 14% for men and 22% for women. Patient education had been utilized by 38% of eligible persons and was increasingly followed by screening colonoscopy. For women, practices that specialized in gynecology were the main providers of FOBT (93%) and patient education (61%). This study provides new insights into the inter-related utilization of colonoscopy, FOBT, and patient education in Germany, and may be particularly informative for the design of strategies to increase CRC screening uptake. It indicates that sex differences in CRC screening test use could result to a large extent from general visits to different types of specialist physicians involved in the CRC screening process.

Nonmedical Costs of Colorectal Cancer Screening With the Fecal Occult Blood Test and Colonoscopy

The nonmedical costs of colorectal cancer screening are unknown. However, they might influence screening uptake and impact the cost-effectiveness of colorectal cancer screening modalities. Consecutive individuals presenting for colorectal cancer screening in the Calgary Health Region were recruited from 4 community laboratory collection sites (fecal occult blood test) and 2 endoscopy units (colonoscopy). Subjects completed a questionnaire including items on time off work for the subject and any accompanying caregiver, travel details, and direct out-of-pocket expenses (bowel prep). Time costs were valued at Government of Canada wage rates. Travel costs included estimated costs for travel by car and actual parking costs and taxi and public transportation fares. Car users' costs were calculated by using a Canadian Automobile Association estimate of motoring costs per kilometer. Costs are in 2006 Canadian dollars. The final sample included 604 subjects who underwent fecal occult blood test (mean age, 62 years; 51% male; 43% employed) and 723 who underwent colonoscopy (mean age, 56; 49% male; 66% employed). Eighty percent of colonoscopy subjects required an accompanying caregiver, compared with only 5% for fecal occult blood test. The nonmedical costs (subject +/- caregiver) averaged $308 for colonoscopy and $36 for fecal occult blood test. The nonmedical costs of colorectal cancer screening are substantial, especially for colonoscopy. However, the costs are similar with repeated fecal occult blood tests. These costs might be one factor accounting for low colorectal cancer screening uptake rates. Nonmedical costs should be incorporated into economic analyses of colorectal cancer screening.
