Predictors of Colorectal Cancer Screening Among African American Men Living with HIV.

African American men living with HIV are at high risk of colorectal cancer (CRC). Screening to detect CRC is associated with a reduced risk of CRC mortality. However, little is known about CRC screening predictors in this population. This study examined the relation of self-efficacy, a potential mediator of screening that interventions could target, to CRC screening. It also investigated several variables that might identify subpopulations of African American men non-adherent to CRC screening recommendations. We report a secondary analysis on baseline data from a randomized controlled trial of a health promotion intervention for African American men living with HIV. Before their intervention, they completed measures of CRC screening, self-efficacy, marital status, age, education, and adherence to physical activity guidelines and were assessed for obesity. A total of 270 African American men aged 45 to 88 (Mean = 55.07; SD = 6.46) living with HIV participated. About 30% reported CRC screening in the past six months. Multiple logistic regression revealed greater CRC screening self-efficacy and meeting physical activity guidelines were associated with receiving CRC screening. Obese men and men reporting higher education were less likely to report screening. Age and marital status were unrelated to screening. The results of this study suggest CRC screening rates may be low among African American men living with HIV, and interventions targeting self-efficacy may improve their screening uptake. Moreover, public-health efforts to increase screening should prioritize interventions with subpopulations of African American men living with HIV who are physically inactive and obese.

Increasing colorectal cancer in the young population and tailoring of the colorectal cancer screening recommendations in subpopulation: a retrospective single-center study.

The United States Preventive Services Task Force (USPSTF) newly drafted recommendations for colorectal cancer (CRC) screening age in average-risk individuals decreased to 45 years from 50 years. This study evaluates the change in the incidence of CRC, compares the demographic characteristics, characteristics of CRC, survival, and factors affecting the survival of younger (< 50 years) with the older (> 50 years) CRC-diagnosed population of Boston Medical Center (BMC). Also tailors the screening recommendations of CRC based on subpopulations. A retrospective cohort study was conducted from 2004 to 2019 at BMC who underwent colonoscopy, to see newly diagnosed CRC. The analysis was done in R studio version 1.2.5033. The incidence rate of CRC is increasing in the younger population. The CRC in younger population was 350 and older was 2019. The most prevalent site among the younger population was rectum (33.33%), and most of the CRC were diagnosed at an advanced stage. Hispanics were less likely to be diagnosed with CRC in older age group (OR= 0.468, 95% CI 0.285, 0.796). Lower BMI was associated with a higher risk of mortality (p= 0.012). There was no difference in survival in younger and older populations. CRC is increasing in the younger population, and Hispanics are diagnosed with CRC usually at a younger age. Early screening in young populations with average risk and even earlier screening in high-risk populations like Hispanics is warranted for timely recognition for prevention, early management, and reduction of mortality.

National disparities in colorectal cancer screening in patients with comorbid conditions: an analysis of the Behavioral Risk Factor Surveillance System.

Each year, approximately 53,200 people die in the U.S. from colorectal cancer (CRC), indicating a need to increase screening efforts. Some studies have suggested mammography use is higher in patients with comorbid conditions, a reflection of increased follow up. Another study found that patients with obesity were less likely to be screened for CRC than nonobese patients. However, no study has assessed the impact of multiple comorbidities on CRC screening. To analyze CRC screening rates in patients with comorbidities compared with healthy patients, and to assess whether the number of comorbid diagnoses impacted screening rates. A cross sectional analysis of patients who received CRC screening was performed using the 2018 and 2019 Behavioral Risk Factor Surveillance System (BRFSS). Respondents were classified as having had CRC screening if they answered "yes" to either of the following: "Have you ever had a blood stool test?" or "Have you ever had a sigmoidoscopy/colonoscopy?" Respondents younger than age 50 were excluded. A weighted multivariate logistic regression model was constructed to determine adjusted risk ratios (ARR). Confidence intervals (CI) were reported at 95%. We identified 279,784 respondents who met inclusion criteria. Of those, 79.7% (sample n=222,879; population N=46,304,360) of respondents had received CRC screening. Patients with diabetes, hypertension, skin cancer, chronic obstructive pulmonary disease (COPD), arthritis, depression, and chronic kidney disease were significantly more likely to be screened than those without comorbidities. There was no statistically significant difference in screening rates between patients with and without cardiovascular disease. Compared with patients with zero comorbidities, those with one were significantly more likely to receive screening (ARR, 1.11; CI, 1.09-1.12) as were those with two to four (ARR, 1.2; CI, 1.18-1.22). Patients with five or more comorbidities were significantly less likely to be screened than those with two to four (ARR, 1.12; CI, 1.1-1.14). Patients with one or more comorbidities were more likely to be screened than those without comorbidities, but those with five or more conditions were less likely to be screened than patients with two to four conditions. This indicates that physicians may be more fatigued and less likely to recommend CRC screening to patients with many comorbidities compared with patients diagnosed with only a few conditions. The results of this study add to the literature by identifying an interaction between the number of comorbidities and likelihood of being screened for CRC.

National Survey of Patient Factors Associated with Colorectal Cancer Screening Preferences

Recommended colorectal cancer screening modalities vary with respect to safety, efficacy, and cost. Better understanding of the factors that influence patient preference is, therefore, critical for improving population adherence to colorectal cancer screening. To address this knowledge gap, we conducted a panel survey focused on three commonly utilized colorectal cancer screening options [fecal immunochemical test or guaiac-based fecal occult blood test (FIT/gFOBT), multi-target stool DNA (mt-sDNA) test, and colonoscopy] with a national sample of U.S. adults, ages 40-75 years and at average risk of colorectal cancer, in November 2019. Of 5,097 panelists invited to participate, 1,595 completed the survey (completion rate, 31.3%). Our results showed that when presented a choice between two colorectal cancer screening modalities, more respondents preferred mt-sDNA (65.4%) over colonoscopy, FIT/gFOBT (61%) over colonoscopy, and mt-sDNA (66.9%) over FIT/gFOBT. Certain demographic characteristics and awareness of and/or experience with various screening modalities influenced preferences. For example, uninsured people were more likely to prefer stool-based tests over colonoscopy [OR, 2.53; 95% confidence interval (CI), 1.22-5.65 and OR, 2.73; 95% CI, 1.13-7.47]. People who had heard of stool-based screening were more likely to prefer mt-sDNA over FIT/gFOBT (OR, 2.07; 95% CI, 1.26-3.40). People who previously had a stool-based test were more likely to prefer FIT/gFOBT over colonoscopy (OR, 2.75; 95% CI, 1.74-4.41), while people who previously had a colonoscopy were less likely to prefer mt-sDNA or FIT/gFOBT over colonoscopy (OR, 0.39; 95% CI, 0.24-0.63 and OR, 0.40; 95% CI, 0.26-0.62). Our survey demonstrated broad patient preference for stool-based tests over colonoscopy, contrasting the heavy reliance on colonoscopy for colorectal cancer screening in clinical practice and highlighting the importance of considering patient preference in colorectal cancer screening recommendations. PREVENTION RELEVANCE: Our national survey demonstrated broad patient preference for stool-based tests over colonoscopy, contrasting the heavy reliance on colonoscopy for colorectal cancer screening in clinical practice and highlighting the importance of considering patient preference in colorectal screening recommendations.

An examination of socioeconomic and racial/ethnic disparities in the awareness, knowledge and utilization of three colorectal cancer screening modalities.

While colorectal cancer (CRC) mortality rates have been decreasing, disparities by socioeconomic status (SES) and race/ethnicity persist. CRC screening rates remain suboptimal among low SES and racial/ethnic minority populations, despite the availability of multiple screening modalities. Understanding awareness, knowledge, and utilization of common screening modalities within different racial/ethnic and SES groups is critical to inform efforts to improve population screening uptake and reduce disparities in CRC-related health outcomes. Through the theoretical lenses of diffusion of innovation and fundamental cause theory, we examined the associations of race/ethnicity and SES with awareness, knowledge, and utilization of three guideline recommended CRC screening strategies among individuals at average risk for CRC. Data were obtained from a survey of a nationally representative panel of US adults conducted in November 2019. The survey was completed by 31.3% of invited panelists (1595 of 5097). Analyses were focused on individuals at average risk for CRC, aged 45–75 for awareness and knowledge outcomes (n = 1062) and aged 50–75 for utilization outcomes (n = 858). Analyses revealed racial/ethnic and SES disparities among the three CRC screening modalities, with more racial/ethnic and SES differences observed in the awareness, knowledge, and utilization of screening colonoscopy and mt-sDNA than FIT/gFOBT. Patterns of disparities are consistent with previous research showing that inequities in social and economic resources are associated with an imbalanced adoption of medical innovations. Our findings demonstrate a need to increase awareness, knowledge, and access of various CRC screening modalities in specific populations defined by race/ethnicity or SES indicators. Efforts to increase CRC screening should be tailored to the needs and social-cultural context of populations. Interventions addressing inequalities in social and economic resources are also needed to achieve more equitable adoption of CRC screening modalities and reduce disparities in CRC-related health outcomes.

Abstract P12: Colorectal cancer screening in Appalachian Kentucky primary care clinics during COVID-19

Abstract Background: Colorectal cancer (CRC) mortality is disproportionately higher in Appalachian counties of Kentucky than in non-Appalachian regions. Part of the mortality gap can be explained by lower screening rates in Appalachian counties. Researchers at Markey Cancer Center partnered with primary care clinics in eastern Kentucky to address this disparity by identifying strategies to implement evidence-based interventions (EBIs) to improve CRC screening and follow-up in Appalachian Kentucky. Methods: Members of the research team conducted formative research activities to identify multilevel barriers to CRC screening. A menu of EBIs was then created to address these barriers, and clinic champions selected EBIs that were feasible in their respective practices. However, because of restrictions during COVID-19, clinics experienced multiple changes to workflow and operations, necessitating modifications to program activities. Over a series of virtual meetings, clinic champions selected adaptations that could allow clinics to continue promoting CRC screening in their practices despite COVID-related limitations. Results: Changes in clinic staffing and workflow resulting from COVID-19 included provider furloughs, a state-mandated pause in elective procedures, mandatory parking lot visits for many in-person visits, and an increase in telehealth. Among our clinic partners, total in-person visits were reduced by nearly half from first to second quarter of 2020, whereas telehealth visits were 23 times higher, though telehealth visits were cut in half by third quarter. To match these changing modes of practice, clinics adapted creative strategies for communicating CRC screening recommendations to patients, including shifting from paper to digital educational tools, promoting screening via telehealth visits, and prioritizing recommendations for stool-based tests over colonoscopy for average-risk patients. As a result, orders for FIT and FIT-DNA were 2 and 3 times higher, respectively, from second to third quarter of 2020. Conclusion: Rural primary care clinics in Appalachia continue to promote CRC screening despite the multiple challenges related to COVID-19. One relevant reference for clinicians is the National Colorectal Cancer Roundtable’s playbook for reigniting CRC screening during COVID-19, a document that promotes stool-based screening for average-risk patients. While elective procedures remain backlogged in rural areas due to state regulations, research partners should emphasize the need to prioritize stool-based CRC screening for average-risk populations and reserve scheduling colonoscopies for high-risk individuals or those with abnormal stool-based test results. While our clinical partners had previously focused on a “colonoscopy first” approach to screening, our findings suggest that our clinic partners increased orders for stool-based CRC tests. Nevertheless, continued outreach is needed to ensure CRC screening rates remain optimal. Citation Format: Aaron J.

The influence of multi-morbidities on colorectal cancer screening recommendations and completion.

Patients' chronic disease burden can influence the likelihood that providers will recommend cancer screening and that patients will participate in it. Using data from the STOP CRC pragmatic study, we examined associations between chronic disease burden and colorectal cancer screening recommendation and use. Participating STOP CRC clinics (n = 26) received either usual care or training to implement a mailed fecal immunochemical test (FIT) outreach program. Selected clinic patients (n = 60,187 patients) were aged 50-74 and overdue for colorectal cancer screening. We used logistic regression to examine the associations between FIT recommendations and completion and patients' chronic disease burden, calculated using the Charlson Comorbidity Index and the Chronic Illness and Disability Payment System. For each index, FIT recommendation odds were 8-9% higher among individuals with minimal chronic disease burden and 13-23% lower among individuals with high chronic disease burden (inverted U-shaped association). Among adults who were ordered a FIT, FIT completion odds were 20% lower for individuals with any, versus no, chronic condition and diminished with increasing disease burden (inverse linear association). Analysis showed an inverted U-shaped association between patients' chronic disease burden and providers' recommendation of a FIT and an inverse linear association between patients' chronic disease burden and FIT completion.

A64 REVIEW OF PATIENTS REFERRED TO THE DIVISION OF DIGESTIVE CARE AND ENDOSCOPY AT DALHOUSIE UNIVERSITY FOR COLORECTAL CANCER SCREENING BASED ON A FAMILY HISTORY OF COLORECTAL CANCER: HOW MANY UNDERWENT COLONOSCOPY?

Abstract Background Nova Scotia has provincial colorectal cancer (CRC) screening for asymptomatic, average risk individuals age 50–74 using fecal immunochemical testing (FIT) every 2 years. However, individuals with 1 or more first degree relatives (FDR) diagnosed with CRC by age 60 have a 2–4 fold increased risk for developing CRC. For these high risk individuals, current guidelines recommend CRC screening with colonoscopy rather than FIT testing. Annually, the Division of Digestive Care &amp; Endoscopy (DCE) at Dalhousie University receives many referrals for patients with a family history of CRC but the percentage of patients who require this procedure is unclear. Aims The objectives of this quality assessment study were to review patients referred to DCE for a family history of CRC to (1) better understand the indication for referral; and (2) determine the percentage of patients undergoing colonoscopy Methods This was a retrospective cross sectional review of a prospectively updated database. The study population was patients referred to DCE from 2012–2019 based on a family history of CRC, as indicated on the referral. Family history of CRC was defined as 1 or more FDRs diagnosed with CRC. High risk patients were those with 2 or more FDRs with CRC or 1 FDR diagnosed by age 60. All patients were reviewed by a single gastroenterologist in clinic. Results A total of 107 referrals from 2012–2019 were reviewed. Of patients age 50 or older, 51/78 (65.4%) had performed at least 1 FIT. The indications for referral were 2 or more FDR diagnosed with CRC for 6/107 (5.6%) patients, 1 FDR diagnosed with CRC by age 60 for 37/107 patients (34.6%) and 1 FDR diagnosed with CRC over age 60 for 33/107 patients (30.8%). The remaining 31/107 patients (29.0%) had no FDR with CRC. Of the 43/107 patients (40.2%) considered high risk based on family history alone, 34/43 (79.1%) underwent colonoscopy and 8/43 (18.6%) opted for FIT testing. Of the 64/107 patients (59.8%) considered average risk based on family history alone, 26/64 (40.6%) had another indication for colonoscopy and 35/64 (54.7%) resumed FIT testing. Conclusions The majority of patients (71.0%) referred to the DCE for a family history of CRC had at least 1 FDR with CRC. Just over half of patients (55.1%) referred to the DCE for a family history of CRC underwent colonoscopy. Strategies to improve the referral process by better capturing high risk individuals are needed. Funding Agencies None

ACG Clinical Guidelines: Colorectal Cancer Screening 2021.

Colorectal cancer (CRC) is the third most common cancer in men and women in the United States. CRC screening efforts are directed toward removal of adenomas and sessile serrated lesions and detection of early-stage CRC. The purpose of this article is to update the 2009 American College of Gastroenterology CRC screening guidelines. The guideline is framed around several key questions. We conducted a comprehensive literature search to include studies through October 2020. The inclusion criteria were studies of any design with men and women age 40 years and older. Detailed recommendations for CRC screening in average-risk individuals and those with a family history of CRC are discussed. We also provide recommendations on the role of aspirin for chemoprevention, quality indicators for colonoscopy, approaches to organized CRC screening and improving adherence to CRC screening. CRC screening must be optimized to allow effective and sustained reduction of CRC incidence and mortality. This can be accomplished by achieving high rates of adherence, quality monitoring and improvement, following evidence-based guidelines, and removing barriers through the spectrum of care from noninvasive screening tests to screening and diagnostic colonoscopy. The development of cost-effective, highly accurate, noninvasive modalities associated with improved overall adherence to the screening process is also a desirable goal.

USPSTF update on sexually transmitted infections

The new draft recommendations from the US Preventive Services Task Force make a significant change to the previous colorectal cancer screening recommendations. This month, Dr. Campos-Outcalt describes that change and provides a look at the financial implications (as stipulated by the Affordable Care Act) of the screening method chosen.

Abstract PO-266: Factors affecting Appalachian Kentuckians' beliefs related to colorectal cancer and colorectal cancer screening

Abstract Background: Rural Appalachian Kentucky has much higher colorectal cancer (CRC) morbidity (50.6 per 100,00) and mortality (19.8 per 100,000) than the U.S. Appalachian Kentucky CRC screening rates are 36% compared with 27% statewide and 53% nationally. This study assessed factors affecting Appalachian Kentuckians’ beliefs related to CRC and CRC screening. Methods: Appalachian Kentuckians 50 years of age and older who were not up-to-date on CRC screening (N = 190) completed a survey including subscales measuring perceived CRC susceptibility and perceived benefits of CRC screening. Mann-Whitney U and Kruskal-Wallis tests compared differences in beliefs and Spearman’s Rho examined the correlation between variables. Results: Sixty-two percent were concerned about developing CRC, and 94.7% had completed CRC screening previously. Participants felt more susceptible to CRC if they had a family history of CRC (p &amp;lt; .01) and if their healthcare provider recommended CRC screening (13.03 versus 12.19, p &amp;lt; .01). Perceived benefits of CRC screening were not significantly associated with demographic or healthcare access variables. Conclusions: Although many participants were concerned about developing CRC, very few had completed CRC screening. These findings and those of previous research provide information to guide tailored interventions to promote CRC screening in Appalachian Kentuckians. Individuals with a family history of cancer may perceive a higher CRC susceptibility and be more likely to complete CRC screening. Healthcare providers’ recommendations for CRC screening can influence perceived CRC susceptibility and potentially influence completion of CRC screening in this population. Citation Format: Mollie E.

Abstract PO-255: A colorectal cancer screening intervention to help increase screening rate within the Harris Health safety-net health care system

Abstract Background: Colorectal Cancer (CRC) is often preventable through regular screening. CRC screening is an evidence-based intervention for early detection and prevention of CRC. However, screening rates are low among medically underserved, minority populations. In collaboration with a local safety-net healthcare system and community clinics, we are implementing a comprehensive, multi-modal CRC prevention program. Our CRC screening program includes community outreach, culturally and linguistically targeted educational point-of-care patient education videos, patient navigation services, and provider and staff training. In 2018, a new component was introduced that includes a CRC survivor led provider-targeted assessment intervention leveraging the American Cancer Society National Colorectal Roundtable’s “80% in Every Community” campaign. Methods: As part of the 80% in Every Community campaign, providers and clinical staff are trained by the CRC survivor staff member to employ strategies from the Roundtable’s toolkit to heighten clinic-level commitment to improving screening rates. Specific strategies include providing tips for evidence-based messaging to reach the unscreened, and training providers to consistently give a strong CRC screening recommendation. A baseline survey was administered ahead of the initial training to assess current clinical practices. Results: Survey data indicated 84.3% (N= 297, 14 clinics) of respondents identified patients not completing and returning FIT as a screening barrier (61.7%-Sometimes and 22.7%-Usually). When asked if they had mechanism to ensure patients given a FIT kit have completed and returned them -75.7 % said Yes and 24.3%-No. In the follow-up question, asking if they had a mechanism to ensure FIT were completed and returned, responses showed: 13.9 % said no mechanism, 43.0% reminder call, 8.1% mail reminder, and 28.6% said a chart reminder to return kit at next visit. 73 respondents wrote in various other mechanisms. Discussion: Respondents believed a systematic mechanism already existed to remind patients to complete their FIT and return it to their clinic. Our next steps are to present these findings to health system leadership and investigate the possibility to strengthen screening patient reminders in various forms of communication to increase FIT completion rate.

Colorectal Cancer Screening in Ghana: Physicians' Practices and Perceived Barriers.

IntroductionGhana has seen a rise in the incidence of colorectal cancer (CRC) over the past decade. In 2011, the Ghana National Cancer Steering Committee created a guideline recommending fecal occult blood testing (FOBT) for CRC screening in individuals over the age of 50. There is limited data available on current Ghanaian CRC screening trends and adherence to the established guidelines.MethodsWe conducted a survey of 39 physicians working at the Komfo Anokye Teaching Hospital in Kumasi, Ghana. The survey evaluates physician knowledge, practice patterns, and perceived personal-, patient- and system-level barriers pertaining to CRC screening.ResultsAlmost 10% of physicians would not recommend colorectal cancer screening for asymptomatic, average risk patients who met the age inclusion criteria set forth in the national guidelines. Only 1 physician would recommend FOBT as an initial screening test for CRC. The top reasons for not recommending CRC screening with FOBT were the lack of equipment/facilities for the test (28.1%) and lack of training (18.8%). The two most commonly identified barriers to screening identified by >85% of physicians, were lack of awareness of screening/not perceiving colorectal cancer as a serious health threat (patient-level) and high screening costs/lack of insurance coverage (system-level).ConclusionDespite creation of national guidelines for CRC screening, there has been low uptake and implementation. This is due to several barriers at the physician-, patient- and system-levels including lack of resources and physician training to follow-up on positive screening results, limited monetary support and substantial gaps in knowledge at the patient level.

Association of Patients’ Perception of Quality of Healthcare Received and Colorectal Cancer Screening Uptake: An Analysis of 2 National Surveys in the USA

Objective: It is not known whether patients’ ratings of the quality of healthcare services they receive truly correlate with the quality of care from their providers. Understanding this association can potentiate improvement in healthcare delivery. We evaluated the association between patients’ ratings of the quality of healthcare services received and uptake of colorectal cancer (CRC) screening. Subjects and Methods: We used 2 iterations of the Health Information National Trends Survey (HINTS) of adults in the USA. HINTS 2007 (4,007 respondents; weighted population = 75,397,128) evaluated whether respondents were up to date with CRC screening while HINTS 4 cycle 3 (1,562 respondents; weighted population = 76,628,000) evaluated whether participants had ever received CRC screening in the past. All included respondents from both surveys were at least 50 years of age, had no history of CRC, and had rated the quality of healthcare services that they had received at their healthcare provider’s office in the previous 12 months. Results: HINTS 2007 data showed that respondents who rated their healthcare as good or fair/poor were significantly less likely to be up to date with CRC screening compared to those who rated their healthcare as excellent. We found comparable results from analysis of HINTS 4 cycle 3 data with poorer uptake of CRC screening as the healthcare quality ratings of respondents reduced. Conclusion: Our study suggests that patients who reported receiving lower quality of healthcare services were less likely to have undergone and be compliant with CRC screening recommendations. It is important to pay close attention to patient feedback surveys in order to improve healthcare delivery.

Hereditary colorectal cancer screening: A 10-year longitudinal cohort study following an educational intervention.

Family history (FH) of a first-degree relative with colorectal cancer (CRC) is associated with two to fourfold increased risk, yet screening uptake is suboptimal despite proven mortality reduction. We developed a FH-based CRC Risk Triage/Management tool for family physicians (FPs), and educational booklet for patients with CRC FH. This report describes physician referral and patient screening behavior 5 and 10 years post-educational intervention, and factors associated with screening.Longitudinal cohort study. FPs/patients in Ontario and Newfoundland, Canada were sent questionnaires at baseline (2005), 5 and 10 years (2015) following tool/booklet receipt. FPs were asked about CRC screening, patients about FH, screening type and timing. “Correct” screening was concordance with tool recommendations.Results reported for 29/121 (24%) FPs and 98/297 (33%) patients who completed all 3 questionnaires. Over 10 years 2/3 patients received the correct CRC screening test at appropriate timing (baseline 75%, 5-year 62%, 10-year 65%). About half reported their FP recommended CRC screening (5-year 51%, 10-year 63%). Fewer than half the patients correctly assessed their CRC risk (44%, 40%, 41%). Patients were less likely to have correct screening timing if female (RR 0.78; 95% CI 0.61, 0.99; p = 0.045). Patients were less likely to have both correct test and timing if moderate/high CRC risk (RR 0.66; 95% CI 0.47, 0.93; p = 0.017) and more likely if their physician recommended screening (RR1.69; 95% CI 1.15, 2.49; p = 0.007).Physician discussion of CRC risk and screening can positively impact patient screening behavior. Efforts are particularly needed for women and patients at moderate/high CRC risk.

Colorectal cancer mortality after spinal cord injury

Context: Colorectal cancer (CRC) is the second leading cause of cancer related deaths in the US. There is paucity of data regarding CRC and the spinal cord injury (SCI) community. Persons with SCI have suboptimal rates of colonoscopies and face extensive barriers to care. The aim of our study was to compare CRC mortality in persons with SCI to CRC mortality in the general population. Design: A prospective follow-up study. Setting: Analysis of the National SCI database. Participants: 54,965 persons with SCI. Interventions: Not applicable. Outcome Measures: Current survival status and causes of death were determined. The expected number of CRC deaths was calculated for the general US population, using ICD-10 codes. Standardized mortality ratios (SMR) were calculated as the ratio of observed to expected CRC deaths stratified by current age, sex, race, time post-injury and neurologic group. Results: The CRC mortality was 146 persons out of 54,965 persons with SCI. The overall SMR was determined to be 1.11 (95% CI [0.94, 1.31]). Among subgroups, one finding was significant and this was for patients with injury level C1-4 with an American Spinal Injury Association Impairment Scale Grade of A, B or C with an SMR of 1.68 ([95% CI [1.03–2.61]). Conclusion: Although persons with SCI receive suboptimal rates of preventative care screenings and report extensive barriers to care, overall, they are not at an increased risk of CRC mortality. The current recommendations for CRC screening should be continued for these individuals while reducing barriers to care.

Hemochromatosis risk genotype is not associated with colorectal cancer or age at its diagnosis.

SummaryHomozygotes for the higher penetrance hemochromatosis risk allele, HFE c.845G>A (p.Cys282Tyr, or C282Y), have been reported to be at a 2- to 3-fold increased risk for colorectal cancer (CRC). These results have been reported for small sample size studies with no information about age at diagnosis for CRC. An association with age at diagnosis might alter CRC screening recommendations. We analyzed two large European ancestry datasets to assess the association of HFE genotype with CRC risk and age at CRC diagnosis. The first dataset included 59,733 CRC or advanced adenoma cases and 72,351 controls from a CRC epidemiological study consortium. The second dataset included 13,564 self-reported CRC cases and 2,880,218 controls from the personal genetics company, 23andMe. No association of the common hereditary hemochromatosis (HH) risk genotype and CRC was found in either dataset. The odds ratios (ORs) for the association of CRC and HFE C282Y homozygosity were 1.08 (95% confidence interval [CI], 0.91–1.29; p = 0.4) and 1.01 (95% CI, 0.78–1.31, p = 0.9) in the two cohorts, respectively. Age at CRC diagnosis also did not differ by HFE C282Y/C282Y genotype in either dataset. These results indicate no increased CRC risk in individuals with HH genotypes and suggest that persons with HH risk genotypes can follow population screening recommendations for CRC.

Abstract 2354: Multilevel analysis of colorectal cancer screening in southeastern Pennsylvania

Abstract Background: Colorectal cancer (CRC) is a leading cause of mortality in the US. There are racial and socioeconomic disparities in CRC incidence and mortality, in part due to underuse of CRC screening. The goal of this cross-sectional study was to examine multilevel factors associated with CRC screening in Southeastern PA. Methods: We conducted a cross-sectional study using the Public Health Management Corporation's Community Health Database household survey (2010-2015) and American Community Survey data (2010-2014) to examine multilevel factors related to CRC screening via sigmoidoscopy and colonoscopy. We compared adults age 50+ that received CRC screening within 10 years (N=12963) to non-compliant individuals (N=4585), according to American Cancer Society guidelines. We conducted descriptive analyses to compare individual and residential census tract characteristics of the compliant and non-compliant groups. Multilevel regression models including random intercepts for census tracts (CTs) and CT-level socioeconomic status (SES) were used to examine independent associations with CRC screening compliance. P-values &amp;lt;0.05 were considered statistically significant. Results: In bivariate analysis, we observed that individuals that did not comply with CRC screening recommendations were more likely to be younger, male, non-black, unmarried, less educated, uninsured, and current smokers than those in compliance. Non-compliant individuals were also more likely to live in areas with lower SES, shorter distance to public transportation, lower educational attainment, lower median income, and higher percentages of uninsured, unemployed, poverty and households on public assistance compared to those in compliance. In multilevel regression analysis, being unmarried (OR=1.49, 95% CI=1.34-1.65), uninsured (OR=1.65, 95% CI=1.30-2.10), or living in lower SES census tracts (below the first SES quartile: OR=1.48, 95% CI=1.30-1.69 and between the 2nd and 3rd quartile: OR=1.51, 95% CI=1.29-1.75 vs. above the highest quartile) were associated with non-compliance in CRC screening recommendations. There were no interactions detected between race and census tract SES in these models. Conclusions: We identified multilevel factors (marital status, health insurance status, and residential SES) significantly associated with non-compliance to CRC screening recommendations. Individuals and CTs with low levels of compliance can be identified and targeted for tailored interventions, such as peer support and community education about CRC in future studies. Future studies might examine how the availability and location of screening facilities may relate to CRC screening recommendation compliance rates in different neighborhoods.

How nurse practitioners can advocate for local, state, and federal policy to promote colorectal cancer prevention and screening.

Colorectal cancer (CRC) is the second most common cause of cancer deaths for men and women, combined, even though it is the most preventable, treatable, and beatable cancer. Polyp removal during colonoscopy is one major way to help prevent CRC, but it can also be prevented by modifiable risk factor reduction. The National Colorectal Cancer Roundtable's campaign "80% in Every Community" is an effort to address disparities in the less-screened populations and communities. The nurse practitioner (NP) can assist health care organizations to develop policies for high-quality screening programs and create system changes to promote CRC prevention and screening. Professional organizations provide an easy way to become involved in policy change at the health system, local, state, and federal levels. State and federal policies affect patient access to care and adherence to the CRC prevention and screening recommendations. Fourteen states have not yet elected to expand Medicaid. Every NP has the knowledge, skills, and ability to advocate for the expansion of Medicaid in these remaining states to reduce this access to care barrier for underserved patients and communities.
