What Multilevel Interventions Do We Need to Increase the Colorectal Cancer Screening Rate to 80%?

Factors Associated With Mailed Fecal Immunochemical Test Completion in an Integrated Academic-Community Healthcare System

INTRODUCTION

Mailed fecal immunochemical test (FIT) outreach is an effective strategy to increase colorectal cancer (CRC) screening. The aim of this study was to determine the patient-level, clinic-level, and geographic-level factors associated with CRC screening completion in a mailed FIT outreach program.

METHODS

This retrospective cohort study was conducted in the integrated healthcare system of University of Washington Medicine and included patients aged 50-75 years, who were due for CRC screening, and had a primary care encounter in the past 3 years. Eligible patients received mailed outreach that included a letter with information about CRC screening, FIT kit, and a prepaid return envelope. CRC screening and factors associated with completion were obtained from electronic health records and the CRC screening program database.

RESULTS

Of the 9,719 patients who received mailed outreach, 29.6% completed FIT mailed outreach. The median FIT return time was 27 days (interquartile range 14-54). On multivariate analysis, patients with a higher area deprivation index, insured through Medicaid, living without a partner, and whose last primary care visit was >12 months ago were less likely to complete a FIT compared with their counterparts. Over a 12-month period, overall CRC screening across the health system increased by 2 percentage points (68%-70%).

DISCUSSION

Mailed FIT outreach in an integrated academic-community practice was feasible, with 32% of invited patients completing CRC screening by FIT or colonoscopy, on par with published literature. Patient and geographic-level factors were associated with CRC screening completion. These data will inform additional interventions aimed to increase CRC screening participation in this population.

Trends in and factors associated with family physician-performed screening colonoscopies in the United States: 2016-2021

PURPOSE

Family physician (FP)-performed screening colonoscopies can serve as 1 strategy in the multifaceted strategy necessary to improve national colorectal cancer screening rates, particularly in rural areas where specialist models can fail. However, little research exists on the performance of this strategy in the real world. In this study, we evaluated trends in and factors associated with FP-performed screening colonoscopies in the United States between 2016 and 2021.

METHODS

Using national data from Merative's Marketscan insurance claims database, we estimate the proportion of screening colonoscopies performed by FPs. We use logistic regression models to evaluate factors independently associated with FP-performed colonoscopies.

RESULTS

The percentage of screening colonoscopies performed by FPs exhibited a downward trend from 11.32% in 2016 to 6.73% in 2021, with the largest decrease occurring among patients from the most rural areas. FPs were more likely to perform colonoscopies on slightly older patients, male patients, and rural patients. Patients were less likely to receive FP-performed colonoscopies in large metropolitan areas compared to lesser populated areas. Patients were more likely to receive FP-performed colonoscopies in the Midwest, South, and West, even after accounting for urban-rural classification.

CONCLUSION

Despite a downward trajectory, FPs perform a substantial proportion of screening colonoscopies in the United States. Changes to the business side of health care delivery may be contributing to the observed decreasing rate. Whether through spatial or relational proximity, FPs may be better positioned to provide colonoscopy to some rural, male, and older patients who otherwise may not have been screened. Policy changes to expand the FP workforce, particularly in rural areas, are likely necessary to slow or reverse the downward trend of FP-performed screening colonoscopies.

Longitudinal adherence to annual colorectal cancer screening among Black persons living in the United States enrolled in a community-based randomized trial

BACKGROUND

This study examined repeat colorectal cancer screening rates at 12 and 24 months as part of a randomized intervention trial among Black persons living in the United States and factors associated with screening adherence.

METHODS

Participants completed a survey assessing demographics and Preventive Health Model (PHM) factors (e.g., self efficacy, susceptibility) and received either a culturally targeted photonovella plus free fecal immunochemical test (FIT) kits (intervention group) or a standard educational brochure plus free FIT kits (comparison group). FIT return was assessed at 6, 12, and 24 months. Descriptive statistics summarized patterns of repeat screening. Logistic regression models assessed FIT uptake overtime, and demographic and PHM factors associated with screening adherence.

RESULTS

Participants (N = 330) were U.S.-born (93%), non-Hispanic (97%), and male (52%). Initial FIT uptake within 6 months of enrollment was 86.6%, and subsequently dropped to 54.5% at 12 months and 36.6% at 24 months. Higher FIT return rates were observed for the brochure group at 24 months (51.5% vs 33.3% photonovella, p = .023). Multiple patterns of FIT kit return were observed: 37% completed FIT at all three time points (full adherence), 22% completed two of three (partial adherence), 29% completed one of three (partial adherence), and 12% did not return any FIT kits (complete nonadherence). Predictors of full adherence were higher levels of education and self-efficacy.

CONCLUSIONS

Full adherence to repeat screening was suboptimal. Most participants had partial adherence (one or two of three) to annual FIT screening. Future studies should focus on strategies to support repeat FIT screening.

Screening, awareness and challenges for colorectal cancer treatment in Saudi Arabia: an update

Colorectal cancer (CRC) is the second most common cancer in the world. In Saudi Arabia, CRC is the most common cancer in males and the third most common in females, and its incidence rate is rising as the country continues to develop. However, the country does not have a national CRC screening program for CRC. This review aims to review recent studies that have attempted to address and rectify this issue and discern the most notable and prevalent barriers. Despite these efforts, guidelines are still lacking. Two prospective studies have been conducted in recent years, one of which was a national pilot screening program conducted by the Ministry of Health (MOH). While both had a similar number of participants, the colonoscopy rate for patients with a positive fecal immunochemical test (FIT) in the MOH program was only 20% compared to 75.8% in the Al-Kharj program. Awareness of the Saudi population regarding CRC and its screening appears to be insufficient. The most common barriers to patients' willingness to undergo screening were embarrassment, fear, and pain. Barriers to physicians are mostly related to factors outside their hands, such as lack of equipment and time. We conclude that efforts should be made to establish a national screening program and improve awareness of the population and physicians.

Social Vulnerability Index and Survivorship after Colorectal Cancer Resection

BACKGROUND

Race and socioeconomic status incompletely identify patients with colorectal cancer (CRC) at the highest risk for screening, treatment, and mortality disparities. Social vulnerability index (SVI) was designed to delineate neighborhoods requiring greater support after external health stressors, summarizing socioeconomic, household, and transportation barriers by census tract. SVI is implicated in lower cancer center use and increased complications after colectomy, but its influence on long-term prognosis is unknown. Herein, we characterized relationships between SVI and CRC survival.

STUDY DESIGN

Patients undergoing resection of stage I to IV CRC from January 2010 to May 2023 within an academic health system were identified. Clinicopathologic characteristics were abstracted using institutional National Cancer Database and NSQIP. Addresses from electronic health records were geocoded to SVI. Overall survival and cancer-specific survival were compared using Kaplan-Meier and Cox proportional hazards methods.

RESULTS

A total of 872 patients were identified, comprising 573 (66%) patients with colon tumor and 299 (34%) with rectal tumor. Patients in the top SVI quartile (32%) were more likely to be Black (41% vs 13%, p < 0.001), carry less private insurance (39% vs 48%, p = 0.02), and experience greater comorbidity (American Society of Anesthesiologists physical status III: 86% vs 71%, p < 0.001), without significant differences by acuity, stage, or CRC therapy. In multivariable analysis, high SVI remained associated with higher all-cause (hazard ratio 1.48, 95% CI 1.12 to 1.96, p < 0.01) and cancer-specific survival mortality (hazard ratio 1.71, 95% CI 1.10 to 2.67, p = 0.02).

CONCLUSIONS

High SVI was independently associated with poorer prognosis after CRC resection beyond the perioperative period. Acknowledging needs for multi-institutional evaluation and elaborating causal mechanisms, neighborhood-level vulnerability may inform targeted outreach in CRC care.

What makes Indonesian government officials believe in and implement evidence-based policy: The mediating role of religion-science compatibility beliefs

This research is aimed at examining the relationship between religion-science compatibility belief (RSCB) and evidence-based policy (EBP) belief and implementation in Indonesia, a country with the biggest Muslim population in the world. A dataset containing responses to a questionnaire completed by 499 government officials in Indonesia was collected for the partial least square structural equation modeling (PLS-SEM). This study finds a relationship between RSCB and EBP belief and implementation. In addition, EBP belief also affected the implementation of EBP. The effect that RSCB has on EBP implementation was partially mediated by EBP belief. Studying how these beliefs relate to the attitude of policy makers toward science in a sociocultural context is important, considering that the focus of previous research is on different contexts pertaining to levels of education, industrialization, wealth, and democratization. This is important to encourage a more comprehensive understanding of the public about science globally. This study responds to the need for the literature to examine factors influencing EBP beliefs and implementation at the individual level in non-health contexts and developing countries.

Abnormal Colorectal Cancer Test Follow-Up: A Quality Improvement Initiative at a Federally Qualified Health Center

INTRODUCTION/OBJECTIVES

Colonoscopy completion rates after an abnormal fecal immunochemical test (FIT) are suboptimal, resulting in missed opportunities for early detection and prevention of colorectal cancer. Patient navigation and structured follow-up may improve colonoscopy completion, but implementation of these strategies is not widespread.

METHODS

We conducted a quality improvement study using a Plan-Do-Study-Act (PDSA) Model to increase colonoscopy completion after abnormal FIT in a large federally qualified health center serving a diverse and low-income population. Intervention components included patient navigation, and a checklist to promote completion of key steps required for abnormal FIT follow-up. Primary outcome was proportion of patients achieving colonoscopy completion within 6 months of abnormal FIT, assessed at baseline for 156 patients pre-intervention, and compared to 208 patients during the intervention period from April 2017 to December 2019. Drop offs at each step in the follow-up process were assessed.

RESULTS

Colonoscopy completion improved from 21% among 156 patients with abnormal FIT pre-intervention, to 38% among 208 patients with abnormal FIT during the intervention (P < .001; absolute increase: 17%, 95% CI: 6.9%-25.2%). Among the 130 non-completers during the intervention period, lack of completion was attributable to absence of colonoscopy referral for 7.7%; inability to schedule a pre-colonoscopy specialist visit for 71.5%; failure to complete a pre-colonoscopy visit for 2.3%; the absence of colonoscopy scheduling for 9.2%; failure to show for a scheduled colonoscopy for 9.2%.

CONCLUSIONS

Patient navigation and structured follow-up appear to improve colonoscopy completion after abnormal FIT. Additional strategies are needed to achieve optimal rates of completion.

Patient preferences for the design of a pharmacy-based colorectal cancer screening program

PURPOSE

To assess preferences for design of a pharmacy-based colorectal cancer (CRC) screening program (PharmFIT™) among screening-eligible adults in the United States (US) and explore the impact of rurality on pharmacy use patterns (e.g., pharmacy type, prescription pick-up preference, service quality rating).

METHODS

We conducted a national online survey of non-institutionalized US adults through panels managed by Qualtrics, a survey research company. A total of 1,045 adults (response rate 62%) completed the survey between March and April 2021. Sampling quotas matched respondents to the 2010 US Census and oversampled rural residents. We assessed pharmacy use patterns by rurality and design preferences for learning about PharmFIT™; receiving a FIT kit from a pharmacy; and completing and returning the FIT kit.

RESULTS

Pharmacy use patterns varied, with some notable differences across rurality. Rural respondents used local, independently owned pharmacies more than non-rural respondents (20.4%, 6.3%, p < 0.001) and rated pharmacy service quality higher than non-rural respondents. Non-rural respondents preferred digital communication to learn about PharmFIT™ (36% vs 47%; p < 0.001) as well as digital FIT counseling (41% vs 49%; p = 0.02) more frequently than rural participants. Preferences for receiving and returning FITs were associated with pharmacy use patterns: respondents who pick up prescriptions in-person preferred to get their FIT (OR 7.7; 5.3-11.2) and return it in-person at the pharmacy (OR 1.7; 1.1-2.4).

CONCLUSION

Pharmacies are highly accessible and could be useful for expanding access to CRC screening services. Local context and pharmacy use patterns should be considered in the design and implementation of PharmFIT™.

Trends in colorectal cancer screening in the United States, 2012 to 2020

OBJECTIVES

Despite recommendations to increase the uptake of colorectal cancer (CRC) screening, trends in CRC screening vary with sociodemographic status. We aimed to evaluate trends in CRC screening in the US population and subpopulations.

METHODS

A total of 1,082,924 participants aged 50 to 75 from five cycles (2012, 2014, 2016, 2018, and 2020) of the Behavioral Risk Factor Surveillance System were involved. Multivariable logistic regression models were performed to evaluate linear trends in CRC screening utilization from 2012 to 2018. Rao-Scott chi-square tests were used to assess the differences in CRC screening utilization between 2018 and 2020.

RESULTS

The estimated percentage reporting up-to-date with CRC screening increased significantly (P for trend <0.001), from 62.8% (95% CI, 62.4%-63.2%) in 2012 to 66.7% (95% CI, 66.3%-67.2%) in 2018 and 70.4% (95% CI, 69.8%-71.0%) in 2020, in accordance with 2008 US Preventive Services Task Force recommendations. Trends followed similar patterns in most subgroups, although with different magnitudes in several subgroups, primarily those underweight showed a stable percentage over time (P for trend  =  0.170). In 2020, 72.4% of participants reported they were up to date with CRC screening, including the utilization of stool DNA tests and virtual colonoscopy. Colonoscopy was the most commonly used test in 2020 (64.5%), followed by FOBT (12.6%), stool DNA test (5.8%), sigmoidoscopy (3.8%), and virtual colonoscopy (2.7%).

CONCLUSIONS

In this nationally representative survey of the US population from 2012 through 2020, the percentage reporting up to date with CRC screening has increased, but not equally among all subgroups.

Addressing racial and ethnic disparities in US liver cancer care

HCC, the most common form of primary liver cancer, is the fastest rising cause of cancer-related death in the United States. HCC disproportionately affects racial and ethnic minorities in the United States. A practical framework is needed to organize the complex patient, provider, health system, and societal factors that drive these racial and ethnic disparities. In this narrative review, we adapted and applied the National Institute on Minority Health and Health Disparities (NIMHD) Research Framework to the HCC care continuum, as a step toward better understanding and addressing existing HCC-related disparities. We first summarize the literature on HCC-related disparities by race and ethnicity organized by the framework's 5 domains (biological, behavioral, physical/built environment, sociocultural environment, and health care system) and 4 levels (individual, interpersonal, community, and societal) of influence. We then offer strategies to guide future research initiatives toward promotion of health equity in HCC care. Clinicians and researchers may help mitigate further inequities and better address racial and ethnic disparities in HCC care by prioritizing the following in HCC research: (1) increasing racial and ethnic minority representation, (2) collecting and reporting HCC-related data by racial and ethnic subgroups, (3) assessing the patient experience of HCC care by race and ethnicity, and (4) evaluating HCC-specific social determinants of health by race and ethnicity. These 4 priorities will help inform the development of future programs and interventions that are tailored to the unique experiences of each racial and ethnic group.

A "sludge audit" for health system colorectal cancer screening services

OBJECTIVES

"Sludge," or the frictions or administrative burdens that make it difficult for people to attain what they want or need, is an unexplored health care delivery factor that may contribute to deficiencies in colorectal cancer (CRC) screening. We piloted a method to identify and quantify sludge in a southeastern US health system's delivery of CRC screening services.

STUDY DESIGN

Mixed methods sludge audit.

METHODS

We collected and analyzed quantitative (insurance claims, electronic health record, and administrative files) and qualitative (stakeholder interviews and process observations) data associated with CRC screening for instances of sludge. Because they contribute to sludge and reduce system capacity for high-value screening, we also evaluated low-value CRC screening processes.

RESULTS

Although specific results were likely amplified by effects of the COVID-19 pandemic, the sludge audit revealed important areas for improvement. A 60.4% screening rate was observed. Approximately half of screening orders were not completed. The following categories of sludge were identified: communication, time, technology, administrative tasks, paperwork, and low-value care. For example, wait times for screening colonoscopy were substantial, duplicate orders were common, and some results were not accessible in the electronic health record. Of completed screenings, 32% were low-value and 38% were associated with low-value preoperative testing. There was evidence of a differential negative impact of sludge to vulnerable patients.

CONCLUSIONS

Our sludge audit method identified and quantified multiple instances of sludge in a health system's CRC screening processes. Sludge audits can help organizations to systematically evaluate and reduce sludge for more effective and equitable CRC screening.

A Community-Based Survey of Colorectal Cancer Screening Behaviors in Chinese Immigrants Residing in a Major Metropolitan Area

Background

Colorectal cancer is a common cause of screening preventable death in Chinese immigrants, but colorectal cancer screening rates remain low in this population. This study evaluated factors associated with colorectal cancer screening behaviors in Chinese Americans living in New York City.

Methods

Participants were foreign-born Chinese Americans, aged 50 years or older, who completed internet surveys between November 2020 and May 2021 regarding their colorectal cancer screening behaviors. Data were collected on demographics, health care utilization, participants' levels of health literacy, English proficiency, colorectal cancer perceptions and current colorectal cancer screening behaviors. Bivariate analyses using chi-square or t-tests were performed to examine associations between colorectal cancer screening behaviors and participant characteristics.

Results

103 participants were surveyed with a mean age of 71.3 years. Most participants experienced high rates of socioeconomic disadvantage (i.e., less than a high school education, annual household income <$20,000, limited health literacy, and poor English proficiency). 92% were ever screened, 81% were up-to-date on screening, and 85% expressed intention to screen in the future. Almost all participants had a primary care provider and a language concordant provider. Individuals who intended to screen were more fearful of developing colorectal cancer (3.2 vs 2.8, p=0.02) and perceived a colorectal cancer diagnosis with greater severity (3.0 vs 2.7, p=0.07) than those without intention to screen.

Conclusions

In our sample, Chinese immigrants were adversely impacted by multiple social determinants of health but reported high colorectal cancer screening rates. Community-based outreach is critical to ensuring cancer-screening engagement in medically vulnerable populations.

Association between the colorectal cancer screening status of primary care physicians and their patients: Evidence from the Swiss Sentinella practice-based research network

Swiss health insurance reimburses screening for colorectal cancer (CRC) with either colonoscopy or fecal occult blood test (FOBT). Studies have documented the association between a physician's personal preventive health practices and the practices they recommend to their patients. We explored the association between CRC testing status of primary care physicians (PCP) and the testing rate among their patients. From May 2017 to September 2017, we invited 129 PCP who belonged to the Swiss Sentinella Network to disclose their CRC test status and whether they had been tested with colonoscopy or FOBT/other methods. Each participating PCP collected demographic data and CRC testing status from 40 consecutive 50- to 75-year-old patients. We analyzed data from 69 (54%) PCP 50 years or older and 2623 patients. Most PCP were men (81%); 75% were tested for CRC (67% with colonoscopy and 9% with FOBT). Mean patient age was 63; 50% were women; 43% had been tested for CRC (38%, 1000/2623 with colonoscopy and 5%, 131/2623, with FOBT or other non-endoscopic test). In multivariate adjusted regression models that clustered patients by PCP, the proportion of patients tested for CRC was higher among PCP tested for CRC than among PCP not tested (47% vs 32%; OR 1.97; 95% CI 1.36 to 2.85). Since PCP CRC testing status is associated with their patients CRC testing rates, it informs future interventions that will alert PCPs to the influence of their health decisions and motivate them to further incorporate the values and preferences of their patients in their practice.

Factors associated with colorectal cancer screening adherence and the impact of COVID-19 on screening patterns in Connecticut, USA

Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide. Many communities remain under the 80% CRC screening goal. We aimed to identify factors associated with non-adherence to CRC screening and to describe the effect of the COVID-19 pandemic in CRC screening patterns. A retrospective review of patients aged 50-75 years seen at the Griffin Faculty Physicians primary care offices between January 2019 and December 2020 was performed. Logistic regression models were used to identify factors associated with CRC screening non-adherence. Of 12,189 patients, 66.2% had an updated CRC screen. On univariable logistic regression, factors associated with CRC screening non-adherence included age ≤ 55 years [odds ratio (OR) 2.267, p < 0.001], White/Caucasian race (OR 0.858, p = 0.030), Medicaid insurance (OR 2.097, p < 0.001), morbid obesity (OR 1.436, p < 0.001), current cigarette smoking (OR 1.849, p < 0.001), and elevated HbA1c (OR 1.178, p = 0.004). Age, Medicaid insurance, morbid obesity, current smoking, and HbA1c ≥ 6.5% remained significant in the final multivariable model. Compared to 2019, there was an 18.2% decrease in the total number of CRC screening tests in 2020. The proportion of colonoscopy procedures was lower in 2020 compared to the proportion of colonoscopy procedures conducted in 2019 (65.9% vs 81.7%, p < 0.001), with a concurrent increase in stool-based tests. CRC screening rates in our population are comparable to national statistics but below the 80% goal. COVID-19 affected CRC screening. Our results underscore the need to identify patient groups most vulnerable to missing CRC screening and highlight the importance of stool-based testing to bridge screening gaps.

Increasing Fecal Immunochemical Test Return Rates by Implementing Effective “Reminder to Complete Kit” Communication With Participants: A Quality Improvement Study

Background

The incidence of colorectal cancer (CRC) in the United States is increasing. It remains the second leading cause of cancer death in the United States for men and women combined, mainly due to underutilization of screening methods. The American Cancer Society now recommends that adults aged 45 years and older with an average risk of CRC undergo regular screening with either a high-sensitivity stool-based test or structural (visual) examination, depending on patient preference and test availability. The primary objective of this quality improvement project was to determine if reminder methods, such as telephone or letter reminders, increased the return rate of fecal immunochemical tests (FIT) for CRC screening.

Methodology

At public outreach events and daily clinics in the West Texas Panhandle area, participants in the GET FIT program were provided with FIT kits after completing the education on CRC. Participants who fit the inclusion criteria and had received a FIT kit from the program were included. They were instructed on how to perform the test and mail it back. Participants who did not return the completed kits within two weeks were reminded either through (1) a reminder letter, (2) telephone, or (3) a combination of letter reminder and telephone call every two weeks (±three days) for 60 days or five attempts to contact. We de-identified and analyzed the FIT kit return data from April-September 2019 before analyzing these reminder methods. We then calculated the change in return rates from October 2019 to March 2020. Our goal was to increase the FIT return rates by 25% compared to the baseline return rate.

Results

The pre-intervention return rate of kits for April-September 2019 was 61.52%, and the post-intervention return rate for October 2019-March 2020 was 71.85%. This rate was equal to an approximately 16.79% increase in return rates that was statistically significant (p < 0.01). There was a significant difference in the method of reminder between the two groups, but no significant differences in gender and race/ethnicity between the two groups. There was a significant difference in return rates between race/ethnicities in the October-March cohort with black and Hispanic participants having the highest return rates of 82.3% and 77.25%, respectively.

Conclusions

FIT remains one of the primary options for CRC screening. Due to its lower cost and noninvasiveness, FIT was offered to patients at average risk. We demonstrated an increase in return rates, although we did not meet our target return rate goal for this project. This study was limited due to a gradual increase in coronavirus disease 2019 (COVID-19) cases and a subsequent shift and conversation of ongoing research into COVID-19.

Colorectal cancer surveillance by colonoscopy in a prospective, population-based long-term Swiss screening study - outcomes, adherence, and costs

Background The success of colorectal cancer (CRC) screening depends mainly on screening quality, patient adherence to surveillance, and costs. Consequently, it is essential to assess the performance over time.

Methods In 2000, a closed cohort study on CRC screening in individuals aged 50 to 80 was initiated in Uri, Switzerland. Participants who chose to undergo colonoscopy were followed over 18 years. We investigated the adherence to recommended surveillance and collected baseline characteristics and colonoscopy data. Risk factors at screening for the development of advanced adenomas were analyzed. Costs for screening and follow-up were evaluated retrospectively.

Results 1278 subjects with a screening colonoscopy were included, of which 272 (21.3%; 69.5% men) had adenomas, and 83 (6.5%) had advanced adenomas. Only 59.8% participated in a follow-up colonoscopy, half of them within the recommended time interval. Individuals with advanced adenomas at screening had nearly five times the risk of developing advanced adenomas compared to individuals without adenomas (24.3% vs. 5.0%, OR 4.79 CI 2.30–9.95). Individuals without adenomas developed advanced adenomas in 4.9%, including four cases of CRC; three of them without control colonoscopy. The villous component in adenomas smaller than 10 mm was not an independent risk factor. Costs for screening and follow-up added up to CHF 1’934’521 per 1’000 persons screened, almost half of them for follow-up examinations; 60% of these costs accounted for low-risk individuals.

Conclusion Our findings suggest that follow-up of screening colonoscopy should be reconsidered in Switzerland; in particular, long-term adherence is critical. Costs for follow-up could be substantially reduced by adopting less expensive long-term screening methods for low-risk individuals.

Optimal Strategies for Colorectal Cancer Screening

OPINION STATEMENT

Colorectal cancer (CRC) imposes significant morbidity and mortality, yet it is also largely preventable with evidence-based screening strategies. In May 2021, the US Preventive Services Task Force updated guidance, recommending screening begin at age 45 for average-risk individuals to reduce CRC incidence and mortality in the United States (US). The Task Force recommends screening with one of several screening strategies: high-sensitivity guaiac fecal occult blood test (HSgFOBT), fecal immunochemical test (FIT), multi-target stool DNA (mt-sDNA) test, computed tomographic (CT) colonography (virtual colonoscopy), flexible sigmoidoscopy, flexible sigmoidoscopy with FIT, or traditional colonoscopy. In addition to these recommended options, there are several emerging and novel CRC screening modalities that are not yet approved for first-line screening in average-risk individuals. These include blood-based screening or "liquid biopsy," colon capsule endoscopy, urinary metabolomics, and stool-based microbiome testing for the detection of colorectal polyps and/or CRC. In order to maximize CRC screening uptake in the US, patients and providers should engage in informed decision-making about the benefits and limitations of recommended screening options to determine the most appropriate screening test. Factors to consider include the invasiveness of the test, test performance, screening interval, accessibility, and cost. In addition, health systems should have a programmatic approach to CRC screening, which may include evidence-based strategies such as patient education, provider education, mailed screening outreach, and/or patient navigation, to maximize screening participation.

Colorectal Cancer Prevalence and Survival in Cuenca (Spain)

BACKGROUND

Colorectal cancer is the most commonly diagnosed cancer type and the second cause of cancer death in Spain. The primary risk factor for colorectal cancer is age, with 90% of all diagnosed patients aged over 50 years. Prognosis mainly depends on tumour stage.

AIM

Conduct a colorectal cancer prevalence and survival study in Cuenca (Spain) since there are almost no studies based on small populations. This is the first study about survival in screening of colorectal cancer carried out in hospitals in Castilla-La Mancha.

METHODS

Retrospective descriptive cohort study was performed to include patients with colorectal cancer diagnosed by colonoscopy between May 2015 and April 2016, and who were followed up for 48 months. The study considered sociodemographic and clinical data of the patients. Survival curves were estimated using the Kaplan-Meier method. The proportional hazard rate associated with age, gender, stage, and presence of metastasis was calculated using the Cox regression method.

RESULTS

Fifty-seven patients were included in the study. The mean follow-up was 45.5 months. Ten patients died during the study; in seven cases, the cause was colorectal cancer. The percentage of patients alive at a 48-month follow-up was 82.4%.

CONCLUSION

Colon cancer is a high-prevalence pathology, with adenocarcinoma being the most common histology. The results seem to indicate that it affects men more frequently, mortality rises with tumour stage at diagnosis and declines with use of chemotherapy. We present a study that could justify large-scale epidemiological studies for the regional surveillance and evolution of colorectal cancer in Spain.

Operationalizing a Rideshare Intervention for Colonoscopy Completion: Barriers, Facilitators, and Process Recommendations

INTRODUCTION

Transportation is a common barrier to colonoscopy completion for colorectal cancer (CRC) screening. The study aims to identify the barriers, facilitators, and process recommendations to implement a rideshare non-emergency medical transportation (NEMT) intervention following colonoscopy completion within a safety-net healthcare setting.

METHODS

We used informal stakeholder engagement, story boards - a novel user-centered design technique, listening sessions and the nominal group technique to identify the barriers, facilitators, and process to implementing a rideshare NEMT program following colonoscopy completion in a large safety-net healthcare system.

RESULTS

Barriers to implementing a rideshare NEMT intervention for colonoscopy completion included: inability to expand an existing NEMT program beyond Medicaid patients and lack of patient chaperones with rideshare NEMT programs. Facilitators included: commercially available rideshare NEMT platforms that were lower cost and had shorter wait times than the alternative of taxis. Operationalizing and implementing a rideshare NEMT intervention in our healthcare system required the following steps: 1) identifying key stakeholders, 2) engaging stakeholder groups in discussion to identify barriers and solutions, 3) obtaining institutional sign-off, 4) developing a process for reviewing and selecting a rideshare NEMT program, 5) executing contracts, 6) developing a standard operating procedure and 7) training clinic staff to use the rideshare platform.

DISCUSSION

Rideshare NEMT after procedural sedation is administered may improve colonoscopy completion rates and provide one solution to inadequate CRC screening. If successful, our rideshare model could be broadly applicable to other safety-net health systems, populations with high social needs, and settings where procedural sedation is administered.

Impact of Health Insurance, Poverty, and Comorbidities on Colorectal Cancer Screening: Insights from the Medical Expenditure Panel Survey

BACKGROUND

Despite national campaigns and other efforts to improve colorectal cancer (CRC) screening, participation rates remain below targets set by expert panels. We hypothesized that availability and practice patterns of healthcare providers may contribute to this gap.

METHOD

Using data of the Medical Expenditure Panel Survey for the years between 2000 and 2016, we extracted demographic, socioeconomic, and health-related data as well as reported experiences about barriers to care, correlating results with answers about recent participation in colorectal cancer screening. As CRC screening guidelines recommend initiation of testing at age 50, we focused on adults 50 years or older.

RESULTS

We included responses of 163,564 participants for the period studied. There was a significant increase in CRC screening rates over time. Comorbidity burden, poverty, race, and ethnicity independently predicted participation in screening. Lack of insurance coverage and cost of care played an important role as reported barrier. Convenient access to care, represented by availability of appointments beyond typical business hours, and frequency of provider interactions, correlated with higher rates of screening.

CONCLUSION

Our data show a positive effect of educational efforts and healthcare reform with coverage of screening. Easy and more frequent access to individual providers predicted a higher likelihood of completed screening tests. This finding could translate into more widespread implementation of screening programs, as the increasingly common virtual care delivery offers a new and convenient option to patients.

What Is Organized Screening and What Is Its Value?

Most screening in the United States occurs in an opportunistic fashion, although organized screening occurs in some integrated health care systems. Organized colorectal cancer (CRC) screening consists of an explicit screening policy, defined target population, implementation team, health care team for clinical care delivery, quality assurance infrastructure, and method for identifying cancer outcomes. Implementation of an organized screening program offers opportunities to systematically assess the success of the program and develop interventions to address identified gaps in an effort to optimize CRC outcomes. There is evidence of that organized screening is associated with improvements in screening participation and CRC mortality.

Perceived Deterrence Towards Colonoscopy for Colorectal Cancer Screening among Northern Malaysia Population: A Qualitative Study

BACKGROUND

Patients with positive immunochemical faecal occult blood test results were found to have poor compliance for a subsequent colonoscopy procedure. This study was conducted to explore patients' perceived deterrence for colonoscopy following a positive stool test.

METHODS

Using qualitative study method, a phone interview was conducted with 16 patients to elicit their views on the reasons for failure to attend the colonoscopy procedure following a positive stool test. The interviews were audio recorded, transcribed verbatim and translated before proceeded with the data analysis. Content analysis was made on the translated interview, followed by systematic classification of data by major themes.

RESULTS

Reasons for nonattendance were categorized under five main themes; unnecessary test, fear of the procedure, logistic obstacles (subthemes; time constraint, transportation problem), social influences, and having other health priority. Lacking in information about the procedure during the referral process was identified to cause misperception and unnecessary worry towards colonoscopy. Fear of the procedure was commonly cited by female respondents while logistic issues pertaining to time constraint were raised by working respondents.

CONCLUSIONS

More effective communication between patients and health care providers are warranted to avoid misconception regarding colonoscopy procedure. Support from primary care doctors, customer-friendly appointment system, use of educational aids and better involvement from family members were among the strategies to increase colonoscopy compliance.
