Item Baseline Features and Reasons for Nonparticipation in the Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) Study, a Colorectal Cancer Screening Trial(American Medical Association, 2023-07-03) Robertson, Douglas J.; Dominitz, Jason A.; Beed, Alexander; Boardman, Kathy D.; Del Curto, Barbara J.; Guarino, Peter D.; Imperiale, Thomas F.; LaCasse, Andrew; Larson, Meaghan F.; Gupta, Samir; Lieberman, David; Planeta, Beata; Shaukat, Aasma; Sultan, Shanaz; Menees, Stacy B.; Saini, Sameer D.; Schoenfeld, Philip; Goebel, Stephan; von Rosenvinge, Erik C.; Baffy, Gyorgy; Halasz, Ildiko; Pedrosa, Marcos C.; Kahng, Lyn Sue; Cassim, Riaz; Greer, Katarina B.; Kinnard, Margaret F.; Bhatt, Divya B.; Dunbar, Kerry B.; Harford, William V.; Mengshol, John A.; Olson, Jed E.; Patel, Swati G.; Antaki, Fadi; Fisher, Deborah A.; Sullivan, Brian A.; Lenza, Christopher; Prajapati, Devang N.; Wong, Helen; Beyth, Rebecca; Lieb, John G.; Manlolo, Joseph; Ona, Fernando V.; Cole, Rhonda A.; Khalaf, Natalia; Kahi, Charles J.; Kohli, Divyanshoo Rai; Rai, Tarun; Sharma, Prateek; Anastasiou, Jiannis; Hagedorn, Curt; Fernando, Ronald S.; Jackson, Christian S.; Jamal, M. Mazen; Lee, Robert H.; Merchant, Farrukh; May, Folasade P.; Pisegna, Joseph R.; Omer, Endashaw; Parajuli, Dipendra; Said, Adnan; Nguyen, Toan D.; Tombazzi, Claudio Ruben; Feldman, Paul A.; Jacob, Leslie; Koppelman, Rachel N.; Lehenbauer, Kyle P.; Desai, Deepak S.; Madhoun, Mohammad F.; Tierney, William M.; Ho, Minh Q.; Hockman, Heather J.; Lopez, Christopher; Carter Paulson, Emily; Tobi, Martin; Pinillos, Hugo L.; Young, Michele; Ho, Nancy C.; Mascarenhas, Ranjan; Promrat, Kirrichai; Mutha, Pritesh R.; Pandak, William M.; Shah, Tilak; Schubert, Mitchell; Pancotto, Frank S.; Gawron, Andrew J.; Underwood, Amelia E.; Ho, Samuel B.; Magno-Pagatzaurtundua, Priscilla; Toro, Doris H.; Beymer, Charles H.; Kaz, Andrew M.; Elwing, Jill; Gill, Jeffrey A.; Goldsmith, Susan F.; Yao, Michael D.; Protiva, Petr; Pohl, Heiko; Kyriakides, Tassos; CONFIRM Study Group; Medicine, School of MedicineImportance: The Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) randomized clinical trial sought to recruit 50 000 adults into a study comparing colorectal cancer (CRC) mortality outcomes after randomization to either an annual fecal immunochemical test (FIT) or colonoscopy. Objective: To (1) describe study participant characteristics and (2) examine who declined participation because of a preference for colonoscopy or stool testing (ie, fecal occult blood test [FOBT]/FIT) and assess that preference's association with geographic and temporal factors. Design, setting, and participants: This cross-sectional study within CONFIRM, which completed enrollment through 46 Department of Veterans Affairs medical centers between May 22, 2012, and December 1, 2017, with follow-up planned through 2028, comprised veterans aged 50 to 75 years with an average CRC risk and due for screening. Data were analyzed between March 7 and December 5, 2022. Exposure: Case report forms were used to capture enrolled participant data and reasons for declining participation among otherwise eligible individuals. Main outcomes and measures: Descriptive statistics were used to characterize the cohort overall and by intervention. Among individuals declining participation, logistic regression was used to compare preference for FOBT/FIT or colonoscopy by recruitment region and year. Results: A total of 50 126 participants were recruited (mean [SD] age, 59.1 [6.9] years; 46 618 [93.0%] male and 3508 [7.0%] female). The cohort was racially and ethnically diverse, with 748 (1.5%) identifying as Asian, 12 021 (24.0%) as Black, 415 (0.8%) as Native American or Alaska Native, 34 629 (69.1%) as White, and 1877 (3.7%) as other race, including multiracial; and 5734 (11.4%) as having Hispanic ethnicity. Of the 11 109 eligible individuals who declined participation (18.0%), 4824 (43.4%) declined due to a stated preference for a specific screening test, with FOBT/FIT being the most preferred method (2820 [58.5%]) vs colonoscopy (1958 [40.6%]; P < .001) or other screening tests (46 [1.0%] P < .001). Preference for FOBT/FIT was strongest in the West (963 of 1472 [65.4%]) and modest elsewhere, ranging from 199 of 371 (53.6%) in the Northeast to 884 of 1543 (57.3%) in the Midwest (P = .001). Adjusting for region, the preference for FOBT/FIT increased by 19% per recruitment year (odds ratio, 1.19; 95% CI, 1.14-1.25). Conclusions and relevance: In this cross-sectional analysis of veterans choosing nonenrollment in the CONFIRM study, those who declined participation more often preferred FOBT or FIT over colonoscopy. This preference increased over time and was strongest in the western US and may provide insight into trends in CRC screening preferences.Item Breast Cancer Screening, Diagnosis, and Surgery during the Pre- and Peri-pandemic: Experience of Patients in a Statewide Health Information Exchange(Springer Nature, 2023) Milgrom, Zheng Z.; Milgrom, Daniel P.; Han, Yan; Hui, Siu L.; Haggstrom, David A.; Fisher, Carla S.; Mendonca, Eneida A.; Pediatrics, School of MedicineBackground: Measures taken to address the COVID-19 pandemic interrupted routine diagnosis and care for breast cancer. The aim of this study was to characterize the effects of the pandemic on breast cancer care in a statewide cohort. Patients and methods: Using data from a large health information exchange, we retrospectively analyzed the timing of breast cancer screening, and identified a cohort of newly diagnosed patients with any stage of breast cancer to further access the information available about their surgical treatments. We compared data for four subgroups: pre-lockdown (preLD) 25 March to 16 June 2019; lockdown (LD) 23 March to 3 May 2020; reopening (RO) 4 May to 14 June 2020; and post-lockdown (postLD) 22 March to 13 June 2021. Results: During LD and RO, screening mammograms in the cohort decreased by 96.3% and 36.2%, respectively. The overall breast cancer diagnosis and surgery volumes decreased up to 38.7%, and the median time to surgery was prolonged from 1.5 months to 2.4 for LD and 1.8 months for RO. Interestingly, higher mean DCIS diagnosis (5.0 per week vs. 3.1 per week, p < 0.05) and surgery volume (14.8 vs. 10.5, p < 0.05) were found for postLD compared with preLD, while median time to surgery was shorter (1.2 months vs. 1.5 months, p < 0.0001). However, the postLD average weekly screening and diagnostic mammogram did not fully recover to preLD levels (2055.3 vs. 2326.2, p < 0.05; 574.2 vs. 624.1, p < 0.05). Conclusions: Breast cancer diagnosis and treatment patterns were interrupted during the lockdown and still altered 1 year after. Screening in primary care should be expanded to mitigate possible longer-term effects of these interruptions.Item Caregiver Perspectives on Cancer Screening for Persons with Dementia: “Why Put Them Through It?”(Wiley, 2013) Torke, Alexia M.; Schwartz, Peter H.; Holtz, Laura R.; Montz, Kianna; Sachs, Greg A.; Medicine, School of MedicineObjectives: To describe the perspectives of family caregivers toward stopping cancer screening tests for their relatives with dementia and identify opportunities to reduce harmful or unnecessary screening. Design: Focus group study. Setting: Alzheimer's Association support groups for family members of individuals with dementia. Participants: Four focus groups including 32 caregivers (25 female; 24 white, 7 African American, one American/Indian; mean age 65.5, range 49-85). Measurements: Focus group transcripts were transcribed and analyzed using methods of grounded theory. Results: Caregivers considered decisions to stop cancer screening in terms of quality of life and burden on the patient and caregiver. Many described having to intervene in the patient's care to stop unnecessary or harmful screening, and others met resistance when they advocated for stopping. Physicians varied widely in their knowledge of dementia care and willingness to consider cessation of screening. Conclusion: Many family caregivers wish to stop cancer screening tests as dementia progresses and are relieved when physicians bring it up. Caregivers are open to discussions of screening cessation that focus on quality of life, burdens, and benefits. Interventions are needed to increase caregiver and clinician discussion of screening cessation and to increase clinician awareness of the need to reconsider cancer screening in individuals with dementia.Item Colorectal Cancer Screening Programs in Latin America: A Systematic Review and Meta-Analysis(American Medical Association, 2024-02-05) Montalvan-Sanchez, Eleazar E.; Norwood, Dalton A.; Dougherty, Michael; Beas, Renato; Guranizo-Ortiz, Maria; Ramirez-Rojas, Miriam; Morgan, Douglas R.; Imperiale, Thomas F.; Medicine, School of MedicineImportance: Colorectal cancer (CRC) is a leading cause of cancer-related mortality globally, with increasing incidence and mortality in Latin America. CRC screening programs can reduce disease burden, but information on screening programs in Latin America is limited. Objective: To describe characteristics (eg, type of program, uptake, neoplastic yield) of CRC screening programs in Latin America. Data sources: PubMed, Ovid MEDLINE, EMBASE, Cochrane, PsycINFO, Web of Science Core Collection, LILACS, and SciELO were searched from inception to February 2023. Relevant references from bibliographies, conference proceedings, and gray literature were considered. The search strategy included English, Spanish, and Portuguese terms. Study selection: Included were studies of CRC screening programs in Latin America using fecal immunochemical test (FIT) or colonoscopy as the primary screening method. Four reviewers independently assessed study eligibility based on titles, with review of abstracts and full texts as needed. Data extraction and synthesis: Guidelines from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed for data abstraction and quality assessment. Descriptive information was extracted, and data were pooled using a random-effects model. Main outcomes and measures: Program performance indicators included rates of participation and FIT positivity, adenoma detection rate (ADR), advanced adenoma detection rate (AADR), CRC detection rate, and colonoscopy quality indicators. Results: There were 17 studies included from upper middle-income and high-income countries in Latin America with a total of 123 929 participants. Thirteen studies used FIT as the initial screening method, whereas 4 used screening colonoscopy. The participation rate in FIT-based programs was 85.8% (95% CI, 78.5%-91.4%). FIT positivity rates were 15.2% (95% CI, 9.6%-21.8%) for the 50-ng/mL threshold and 9.7% (95% CI, 6.8%-13.0%) for the 100-ng/mL threshold. For FIT-based studies, the pooled ADR was 39.0% (95% CI, 29.3%-49.2%) and CRC detection rate was 4.9% (95% CI, 2.6%-7.9%); for screening colonoscopy-based studies, the pooled ADR was 19.9% (95% CI, 15.5%-24.8%) and CRC detection rate was 0.4% (95% CI, 0.1%-0.8%). Conclusions and relevance: This systematic review and meta-analysis suggests that CRC screening in upper middle-income countries in Latin America is feasible, detecting rates of neoplasia comparable with those of high-income regions. Population-based screening programs should be developed or enhanced in these settings. There is a knowledge gap regarding feasibility and yield of screening programs in lower middle-income countries.Item Comparative Effectiveness of 2 Interventions to Increase Breast, Cervical, and Colorectal Cancer Screening Among Women in the Rural US: A Randomized Clinical Trial(American Medical Association, 2023-04-02) Champion, Victoria L.; Paskett, Electra D.; Stump, Timothy E.; Biederman, Erika B.; Vachon, Eric; Katz, Mira L.; Rawl, Susan M.; Baltic, Ryan D.; Kettler, Carla D.; Seiber, Eric E.; Xu, Wendy Y.; Monahan, Patrick O.; Biostatistics and Health Data Science, School of MedicineImportance: Women living in rural areas have lower rates of breast, cervical, and colorectal cancer screening compared with women living in urban settings. Objective: To assess the comparative effectiveness of (1) a mailed, tailored digital video disc (DVD) intervention; (2) a DVD intervention plus telephonic patient navigation (DVD/PN); and (3) usual care with simultaneously increased adherence to any breast, cervical, and colorectal cancer screening that was not up to date at baseline and to assess cost-effectiveness. Design, setting, and participants: This randomized clinical trial recruited and followed up women from rural Indiana and Ohio (community based) who were not up to date on any or all recommended cancer screenings. Participants were randomly assigned between November 28, 2016, and July 1, 2019, to 1 of 3 study groups (DVD, DVD/PN, or usual care). Statistical analyses were completed between August and December 2021 and between March and September 2022. Intervention: The DVD interactively assessed and provided messages for health beliefs, including risk of developing the targeted cancers and barriers, benefits, and self-efficacy for obtaining the needed screenings. Patient navigators counseled women on barriers to obtaining screenings. The intervention simultaneously supported obtaining screening for all or any tests outside of guidelines at baseline. Main outcomes and measures: Receipt of any or all needed cancer screenings from baseline through 12 months, including breast, cervical, and colorectal cancer, and cost-effectiveness of the intervention. Binary logistic regression was used to compare the randomized groups on being up to date for all and any screenings at 12 months. Results: The sample included 963 women aged 50 to 74 years (mean [SD] age, 58.6 [6.3] years). The DVD group had nearly twice the odds of those in the usual care group of obtaining all needed screenings (odds ratio [OR], 1.84; 95% CI, 1.02-3.43; P = .048), and the odds were nearly 6 times greater for DVD/PN vs usual care (OR, 5.69; 95% CI, 3.24-10.5; P < .001). The DVD/PN intervention (but not DVD alone) was significantly more effective than usual care (OR, 4.01; 95% CI, 2.60-6.28; P < .001) for promoting at least 1 (ie, any) of the needed screenings at 12 months. Cost-effectiveness per woman who was up to date was $14 462 in the DVD group and $10 638 in the DVD/PN group. Conclusions and relevance: In this randomized clinical trial of rural women who were not up to date with at least 1 of the recommended cancer screenings (breast, cervical, or colorectal), an intervention designed to simultaneously increase adherence to any or all of the 3 cancer screening tests was more effective than usual care, available at relatively modest costs, and able to be remotely delivered, demonstrating great potential for implementing an evidence-based intervention in remote areas of the midwestern US.Item Contribution of patient, physician, and environmental factors to demographic and health variation in colonoscopy follow-up for abnormal colorectal cancer screening test results(Wiley, 2017-09-15) Partin, Melissa R.; Gravely, Amy; Burgess, James F., Jr.; Haggstrom, David; Lillie, Sarah E.; Nelson, David B.; Nugent, Sean; Shaukat, Aasma; Sultan, Shahnaz; Walter, Louise C.; Burgess, Diana J.; Medicine, School of MedicineBACKGROUND: Patient, physician, and environmental factors were identified, and the authors examined the contribution of these factors to demographic and health variation in colonoscopy follow-up after a positive fecal occult blood test/fecal immunochemical test (FOBT/FIT) screening. METHODS: In total, 76,243 FOBT/FIT-positive patients were identified from 120 Veterans Health Administration (VHA) facilities between August 16, 2009 and March 20, 2011 and were followed for 6 months. Patient demographic (race/ethnicity, sex, age, marital status) and health characteristics (comorbidities), physician characteristics (training level, whether primary care provider) and behaviors (inappropriate FOBT/FIT screening), and environmental factors (geographic access, facility type) were identified from VHA administrative records. Patient behaviors (refusal, private sector colonoscopy use) were estimated with statistical text mining conducted on clinic notes, and follow-up predictors and adjusted rates were estimated using hierarchical logistic regression. RESULTS: Roughly 50% of individuals completed a colonoscopy at a VHA facility within 6 months. Age and comorbidity score were negatively associated with follow-up. Blacks were more likely to receive follow-up than whites. Environmental factors attenuated but did not fully account for these differences. Patient behaviors (refusal, private sector colonoscopy use) and physician behaviors (inappropriate screening) fully accounted for the small reverse race disparity and attenuated variation by age and comorbidity score. Patient behaviors (refusal and private sector colonoscopy use) contributed more to variation in follow-up rates than physician behaviors (inappropriate screening). CONCLUSIONS: In the VHA, blacks are more likely to receive colonoscopy follow-up for positive FOBT/FIT results than whites, and follow-up rates markedly decline with advancing age and comorbidity burden. Patient and physician behaviors explain race variation in follow-up rates and contribute to variation by age and comorbidity burden. Cancer 2017;123:3502-12. Published 2017.

Materials and methods: In this retrospective time-trend analysis, we obtained the numbers of colonoscopies and non-invasive tests performed monthly during the pandemic and the year prior to it. We obtained colonoscopy data from five endoscopy units with the indication determined by dual independent review. Monthly numbers of completed fecal immunochemical (FIT) and FIT-DNA tests were obtained from the electronic medical records of both health systems. Trends in testing, numbers, and stage of incident CRCs diagnosed during the 30-month interval were examined using Poisson regression and logistic regression, respectively. Results: From January 2019 to June 2021, we identified 16,939 FIT tests, 2,942 FIT-DNA tests, and 38,332 colonoscopies from the two health systems, and 368 colorectal cancers (105 early stage, 263 advanced stage) from the private hospital system. Overall colonoscopy volume declined by 18.7% (from 16,483 to 13,393) in 2020 compared to 2019 in both health systems, returning to baseline in 2021. Non-invasive tests declined by 21.9% in 2020, but increased in 2021 due to greater use of FIT/DNA. Compared to 2019, incident CRCs declined in 2020 but rebounded in 2021, with no difference in early versus late-stage cancers. Conclusions: These trends in CRC screening tests may be useful for modeling the effects of the pandemic on the longer-term outcomes of CRC incidence and mortality.Item Health Literacy among Medically Underserved: The Role of Demographic Factors, Social Influence, and Religious Beliefs(Taylor & Francis, 2017-11) Christy, Shannon M.; Gwede, Clement K.; Sutton, Steven K.; Chavarria, Enmanuel; Davis, Stacy N.; Abdulla, Rania; Ravindra, Chitra; Schultz, Ida; Roetzheim, Richard; Meade, Cathy D.; Psychology, School of ScienceThe current study examined the sociodemographic and psychosocial variables that predicted being at risk for low health literacy among a population of racially and ethnically diverse patients accessing primary care services at community-based clinics. Participants (N = 416) were aged 50-75 years, currently not up-to-date with colorectal cancer (CRC) screening, at average CRC risk, and enrolled in a randomized controlled trial (RCT) aimed at promoting CRC screening. Participants completed a baseline interview that assessed health literacy as measured by Rapid Estimate of Adult Literacy in Medicine-Revised, sociodemographic factors, and psychosocial variables (e.g., health beliefs) prior to randomization and receipt of an intervention. Thirty-six percent of the participants were found to be at risk for low health literacy. Sociodemographic and psychosocial variables were assessed as predictors of being at risk for low health literacy using logistic regression. In the final model, predictors were male gender, being from a racial/ethnic minority group, being unable to work, having higher social influence scores, and having higher religious belief scores. These findings suggest several patient characteristics that may be associated with low health literacy, and highlight the importance of supporting all patients through simplified and clear communications and information to improve understanding of CRC screening information.Item Higher Serrated Polyp Detection Rates are Associated with Lower Risk for Post Colonoscopy Colorectal Cancer: Data From the New Hampshire Colonoscopy Registry(Wolters Kluwer, 2023) Anderson, Joseph C.; Rex, Douglas K.; Mackenzie, Todd A.; Hisey, William; Robinson, Christina M.; Butterly, Lynn F.; Medicine, School of MedicineIntroduction: We used New Hampshire Colonoscopy Registry data to examine the association between postcolonoscopy colorectal cancer (PCCRC) and sessile serrated detection rates (SSLDRs). Methods: We included patients with either a colonoscopy or a CRC diagnosis in the NH State Cancer Registry. PCCRC was any CRC diagnosed ≥ 6 months after index examination. Results: Of 26,901 patients, 162 were diagnosed with PCCRC. The hazard ratio for PCCRC was lowest for patients whose endoscopists had the highest SSLDR quintile (≥6%) (hazard ratio 0.29; 95% confidence interval 0.16-0.50). Discussion: Endoscopists with higher SSLDRs had lower risks of PCCRC. These data validate SSLDR as a clinically relevant quality measure.Item Low Rates of Lung and Colorectal Cancer Screening Uptake Among a Safety-net Emergency Department Population(Department of Emergency Medicine, School of Medicine, University of California, Irvine, 2022-08-11) Pettit, Nicholas; Ceppa, DuyKhanh; Monahan, Patrick; Emergency Medicine, School of MedicineIntroduction: A suspected diagnosis of cancer through an emergency department (ED) visit is associated with poor clinical outcomes. The purpose of this study was to explore the rate at which ED patients attend cancer screenings for lung, colorectal (CRC), and breast cancers based on national guidelines set forth by the United States Preventive Services Task Force (USPSTF). Methods: This was a prospective cohort study. Patients were randomly approached in the Eskenazi Hospital ED between August 2019-February 2020 and were surveyed to determine whether they would be eligible and had attended lung, CRC, and breast cancer screenings, as well as their awareness of lung cancer screening with low-dose computed tomography (LDCT). Patients who were English-speaking and ≥18 years old, and who were not critically ill or intoxicated or being seen for acute decompensated psychiatric illness were offered enrollment. Enrolled subjects were surveyed to determine eligibility for lung, colorectal, and breast cancer screenings based on guidelines set by the USPSTF. No cancer screenings were actually done during the ED visit. Results: A total of 500 patients were enrolled in this study. More participants were female (54.4%), and a majority were Black (53.0%). Most participants had both insurance (80.2%) and access to primary care (62.8%). Among the entire cohort, 63.0% identified as smokers, and 62.2% (140/225) of the 50- to 80-year-old participants qualified for lung cancer screening. No patients were screened for lung cancer in this cohort (0/225). Only 0.6% (3/500) were aware that LDCT was the preferred method for screening. Based on pack years, 35.5% (32/90) of the patients who were 40-49 years old and 6.7% (6/90) of those 30-39 years old would eventually qualify for screening. Regarding CRC screening, 43.6% (218/500) of the entire cohort was eligible. However, of those patients only 54% (118/218) had been screened. Comparatively, 77.7% (87/112) of the eligible females had been screened for breast cancer, but only 54.5% (61/112) had been screened in the prior two years. Conclusion: Many ED patients are not screened for lung/colorectal/breast cancers even though many are eligible and have reported access to primary care. This study demonstrates an opportunity and a need to address cancer screening in the ED.
