Item Adenoma Detection Rate in Asymptomatic Patients with Positive Fecal Immunochemical Tests(Springer, 2018-05) Kligman, Eugene; Li, Wenfang; Eckert, George J.; Kahi, Charles; Medicine, School of MedicineBackground and Aims The adenoma detection rate (ADR) is a powerful measure of screening colonoscopy quality. Patients who undergo colonoscopy for the evaluation of a positive fecal immunochemical test (FIT) have increased prevalence of colorectal neoplasia, but it is not known whether separate quality benchmarks are required. The aim of this study was to compare the conventional ADR to the ADR of colonoscopies performed for the evaluation of positive FIT, in asymptomatic average-risk patients. Methods Patients ≥ 50 years old who underwent colonoscopy for the evaluation of a positive FIT between January 1, 2013, and July 31, 2014, at a tertiary Veterans Affairs Medical Center were identified. FIT performed for any indication other than average-risk screening was excluded. The comparison group included average-risk patients ≥ 50 years old undergoing screening colonoscopy during the same time frame. The two groups were compared for ADR, advanced neoplasm [adenoma ≥ 10 mm, tubulovillous, high-grade dysplasia, CRC, sessile serrated polyp (SSP) ≥ 10 mm], CRC, and SSP detection after propensity score adjustment using a logistic regression model adjusted for endoscopist. Results There were 207 patients in the FIT group and 601 in the screening colonoscopy comparison group. After propensity score adjustment, ADR (72.9 vs. 50.0%, p = 0.003), number of adenomas per colonoscopy (3.3 ± 3.6 vs. 1.4 ± 2.3, p = 0.033), and advanced neoplasm detection rate (32.4 vs. 11.0%, p < 0.0001) were significantly higher in the FIT group. There were no significant differences in the number of CRC and the SSP detection rate. Conclusions In this cohort of average-risk Veterans, the ADR of colonoscopies performed for the evaluation of a positive FIT was higher than the ADR of screening colonoscopies. Patients with a positive FIT also had significantly more adenomas per colonoscopy and advanced neoplasms. These findings suggest that the quality of colonoscopies performed for a positive FIT is insufficiently assessed by the conventional ADR and requires additional quality metrics.Item Advances in CRC prevention: screening and surveillance(Elsevier, 2018) Dekker, Evelien; Rex, Douglas K.; Medicine, School of MedicineColorectal cancer (CRC) is amongst the most commonly diagnosed cancers and causes of death from cancer across the world. CRC can, however, be detected in asymptomatic patients at a curable stage, and several studies have shown lower mortality among patients who undergo screening compared to those who do not. Using colonoscopy in CRC screening also results in the detection of precancerous polyps that can be directly removed during the procedure, thereby reducing the incidence of cancer. In the past decade, convincing evidence has appeared that the effectiveness of colonoscopy as CRC prevention tool is associated with the quality of the procedure. This review aims to provide an up-to-date overview of recent efforts to improve colonoscopy effectiveness of by enhancing detection and improving the completeness and safety of resection of colorectal lesions.Item AGA White Paper: Roadmap for the Future of Colorectal Cancer Screening in the United States(Elsevier, 2020) Melson, Joshua E.; Imperiale, Thomas F.; Itzkowitz, Steven H.; Llor, Xavier; Kochman, Michael L.; Grady, William M.; Schoen, Robert E.; Burke, Carol; Shaukat, Aasma; Rabeneck, Linda; Ladabaum, Uri; Bresalier, Robert; Spiegel, Brennan; Yee, Judy; Wang, Thomas; Lieberman, David; Komanduri, Srinadh; Muthusamy, V.

The clinicians and parents of 409 children with CH regionally identified in 2007 were invited to participate in a voluntary survey. Responses relating to treatment, monitoring practices, educational resources, genetic counseling, and services provided/received were collected from 214 clinicians and 77 parents. In total, 99% had undergone a confirmatory test following positive newborn screening and 55% had imaging at diagnosis, but only 50% were identified as having the etiology identified. Thyroid withdrawal challenge testing was the choice method for re-evaluating thyroid function, but the approach varied. Clinician and parent responses to education and genetic counseling also differed. Clinicians report face-to-face education as the most common method, with less than 50% providing handouts to patients. Only 14% of patients were referred to a genetics counselor. Of parents reporting on their educational experience, 86% received face-to-face education from a pediatric endocrinologist and 4% received education from a genetic counselor. Only 65%, however, were satisfied with their education. These survey data suggest a lack of a standardized approach to diagnosis, follow-up, education, and genetic counseling. This collaborative effort provides insight into developing three-year follow-up, education and genetic counseling guidelines for children diagnosed with CH.Item Does Increased Adenoma Detection Reduce the Risk of Colorectal Cancer, and How Good Do We Need to Be?(Springer, 2019-03) Dilly, Christen K.; Kahi, Charles J.; Medicine, School of MedicinePurpose of Review Colorectal cancer (CRC) is largely preventable with colonoscopy and other screening modalities. However, the effectiveness of screening and surveillance depends on the quality of the colonoscopy exam. Adenoma detection rate (ADR) is the best-validated metric by which we measure individual physicians’ performance. Recent Findings Recent evidence suggests that ADR benchmarks may be inappropriately low. There is proof that improving ADR leads to significant reductions in post-colonoscopy CRC (PCCRC). Two studies have demonstrated that when a colonoscopy is performed by physicians with higher ADRs, patients are less likely to have advanced adenomas on surveillance and less likely to develop or die from PCCRC. Finally, there is at least some evidence that higher ADRs do not lead to more cumulative surveillance exams. Summary The ADR is a useful outcome measure that can provide individual endoscopists and their patients with information about the likelihood of developing PCCRC. To achieve the lowest possible PCCRC rate, we should be striving for higher ADRs. While strategies and innovations may help a bit in improving ADRs, our efforts should focus on ensuring a complete mucosal exam for each patient. Behavioral psychology theories may provide useful frameworks for studying motivating factors that drive a careful exam.Item Economic Evaluation of Tailored Web versus Tailored Telephone-Based Interventions to Increase Colorectal Cancer Screening among Women(AACR, 2020-03) Lairson, David R.; Chung, Tong Han; Huang, Danmeng; Stump, Timothy E.; Monahan, Patrick O.; Christy, Shannon M.; Rawl, Susan M.; Champion, Victoria L.; School of NursingScreening for colorectal cancer is cost-effective, but many U.S. women are nonadherent, and the cost-effectiveness of web-based tailored screening interventions is unknown. A randomized controlled trial, COBRA (Increasing Colorectal and Breast Cancer Screening), was the source of information for the economic evaluation. COBRA compared screening among a Usual Care group to: (i) tailored Phone Counseling intervention; (ii) tailored Web intervention; and (iii) tailored Web + Phone intervention groups. A sample of 1,196 women aged 50 to 75 who were nonadherent to colorectal cancer screening were recruited from Indiana primary care clinics during 2013 to 2015. Screening status was obtained through medical records at recruitment with verbal confirmation at consent, and at 6-month follow-up via medical record audit and participant self-report. A "best sample" analysis and microcosting from the patient and provider perspectives were applied to estimate the costs and effects of the interventions. Statistical uncertainty was analyzed with nonparametric bootstrapping and net benefit regression analysis. The per participant cost of implementing the Phone Counseling, Web-based, and Web + Phone Counseling interventions was $277, $314, and $336, respectively. The incremental cost per person screened for the Phone Counseling compared with no intervention was $995, while the additional cost of Web and the Web + Phone compared with Phone Counseling did not yield additonal persons screened. Tailored Phone Counseling significantly increased colorectal cancer screening rates compared with Usual Care. Tailored Web interventions did not improve the screening rate compared with the lower cost Phone Counseling intervention.Item Epidemiology of colorectal cancer.(IJMEG, 2016) Marley, Andrew R.; Nan, Hongmei; Department of Epidemiology, Richard M. Fairbanks School of Public HealthColorectal cancer is currently the third deadliest cancer in the United States and will claim an estimated 49,190 U.S. lives in 2016. The purpose of this review is to summarize our current understanding of this disease, based on nationally published statistics and information presented in peer-reviewed journal articles. Specifically, this review will cover the following topics: descriptive epidemiology (including time and disease trends both in the United States and abroad), risk factors (environmental, genetic, and gene-environment interactions), screening, prevention and control, and treatment. Landmark discoveries in colorectal cancer risk factor research will also be presented. Based on the information reviewed for this report, we suggest that future U.S. public health efforts aim to increase colorectal cancer screening among African American communities, and that future worldwide colorectal cancer epidemiology studies should focus on researching nutrient-gene interactions towards the goal of improving personalized treatment and prevention strategies.Item Evaluation of Race and Ethnicity Across a Statewide System of Early Autism Evaluation(Elsevier, 2023-03) Martin, Ann Marie; Ciccarelli, Mary R.; Swigonski, Nancy; McNally Keehn, Rebecca; Pediatrics, School of MedicineWe evaluated racial and ethnic disparities across the Early Autism Evaluation Hub system, a statewide network for autism diagnosis. Our findings suggest that this system has the potential to reduce longstanding disparities in autism spectrum disorder diagnosis for children from racial and ethnic minority backgrounds.Item Follow-up of Mothers with Suspected Postpartum Depression from Pediatrics Clinics(Frontiers, 2017-10-03) Bauer, Nerissa S.; Ofner, Susan; Pottenger, Amy; Carroll, Aaron E.; Downs, Stephen M.; Pediatrics, School of MedicinePurpose Pediatric providers are increasingly screening for postpartum depression (PD), yet, it is unknown how often mothers comply with recommendations to seek treatment. The objectives were to describe the rate at which mothers with suspected PD seek treatment and explore factors that predict help-seeking behavior. Design and methods Mothers were recruited from four pediatric clinics after identification using the Child Health Improvement through Computer Automation (CHICA) system. Mothers with a positive screen were invited to participate in a telephone interview between January 2012 and December 2014. Mothers reported if they sought treatment or called a community resource. Results 73 of 133 eligible mothers participated (55% response rate). Fifty women recalled a recommendation to seek help. Only 43.8% (32/73) made a follow-up appointment with an adult provider and even fewer kept the appointment. Conclusion A majority of mothers suspected of having PD recalled a referral for further intervention; yet, less than half took action. Further investigation of barriers of help-seeking behavior is warranted.Item GA White Paper: Challenges and Gaps in Innovation for the Performance of Colonoscopy for Screening and Surveillance of Colorectal Cancer(Elsevier, 2022) Komanduri, Srinadh; Dominitz, Jason A.; Rabeneck, Linda; Kahi, Charles; Ladabaum, Uri; Imperiale, Thomas F.; Byrne, Michael F.; Lee, Jeffrey K.; Lieberman, David; Wang, Andrew Y.; Sultan, Shahnaz; Pohl, Heiko; Muthusamy, V. Raman; Medicine, School of MedicineIn 2018 the American Gastroenterological Association’s (AGA) Center for GI Innovation and Technology (CGIT) convened a consensus conference, entitled, “Colorectal Cancer Screening and Surveillance: Role of Emerging Technology and Innovation to Improve Outcomes.” The conference participants, which included more than 60 experts in colorectal cancer (CRC), considered recent improvements in CRC screening rates and polyp detection, persistent barriers to colonoscopy uptake, and opportunities for performance improvement and innovation. This white paper originates from that conference. It aims to summarize current patient- and physician-centered gaps and challenges in colonoscopy, diagnostic and therapeutic challenges affecting colonoscopy uptake, and the potential use of emerging technologies and quality metrics to improve patient outcomes.
