Determinants of variations in self-reported barriers to colonoscopy among uninsured patients in a primary care setting

Disparities in Rates of Multitarget Stool DNA Test Completion for Colorectal Cancer Screening

GOALS

The aim was to assess patient adherence to multitarget stool DNA testing as well as factors associated with adherence.

BACKGROUND

In the United States, disparities in colorectal cancer screening exist along racial and socioeconomic lines. While some studies suggest that stool-based screening tests may help reduce the screening gap, the data for multitarget stool DNA testing is unclear.

STUDY

We conducted a single-center retrospective cohort study on multitarget stool DNA testing ordered between April 2020 and July 2021. We calculated the proportion of patients who completed testing and used multivariate logistic regression to identify covariates associated with test adherence.

RESULTS

Among 797 patients ordered for multitarget stool DNA testing, 481 patients (60.4%) completed testing. Adherence rates by patient subgroups ranged from 35.8% to 78.1%. Higher test adherence was found in Asian patients (odds ratio 2.65, 95% CI 1.36-5.18) and those who previously completed colorectal cancer screening (OR 1.45, 95% CI 1.01-2.09), while Black patients (OR 0.58, 95% CI 0.39-0.87), patients with resident primary care physicians (OR 0.34, 95% CI 0.21-0.56), and patients contacted through an outreach program (OR 0.47, 95% CI 0.25-0.87) had lower adherence.

CONCLUSIONS

A significant proportion of patients ordered for multitarget stool DNA testing did not complete testing. Differences in adherence rates among patient subgroups may be reflective of underlying disparities in health care access.

Colonoscopy Outreach for Rural Communities (CORC): A study protocol of a pragmatic randomized controlled trial of a patient navigation program to improve colonoscopy completion for colorectal cancer screening

BACKGROUND

Colonoscopy is one of the primary methods of screening for colorectal cancer (CRC), a leading cause of cancer mortality in the United States. However, up to half of patients referred to colonoscopy fail to complete the procedure, and rates of adherence are lower in rural areas.

OBJECTIVES

Colonoscopy Outreach for Rural Communities (CORC) is a randomized controlled trial to test the effectiveness of a centralized patient navigation program provided remotely by a community-based organization to six geographically distant primary care organizations serving rural patients, to improve colonoscopy completion for CRC.

METHODS

CORC is a type 1 hybrid implementation-effectiveness trial. Participants aged 45-76 from six primary care organizations serving rural populations in the northwestern United States are randomized 1:1 to patient navigation or standard of care control. The patient navigation is delivered remotely by a trained lay-person from a community-based organization. The primary effectiveness outcome is completion of colonoscopy within one year of referral to colonoscopy. Secondary outcomes are colonoscopy completion within 6 and 9 months, time to completion, adequacy of patient bowel preparation, and achievement of cecal intubation. Analyses will be stratified by primary care organization.

DISCUSSION

Trial results will add to our understanding about the effectiveness of patient navigation programs to improve colonoscopy for CRC in rural communities. The protocol includes pragmatic adaptations to meet the needs of rural communities and findings may inform approaches for future studies and programs.

COLORECTAL CANCER: ASSOCIATION BETWEEN SOCIODEMOGRAPHIC VARIABLES AND THE ADHERENCE TO CANCER SCREENING

BACKGROUND

Colorectal cancer (CRC) is a worldwide health problem whose control depends on public policy establishment and effective prevention and screening programs. In Brazil, there are few studies related to adherence to screening methods.

AIMS

The aim of this study was to evaluate the association between demographic and socioeconomic to adherence to CRC screening with fecal immunochemical test (FIT) among average-risk individuals for CRC.

METHODS

In this prospective cross-sectional study, conducted between March 2015 and April 2016, 1,254 asymptomatic individuals aged 50-75 years, participating in a hospital screening campaign in Brazil, were invited to participate in the study.

RESULTS

The adherence rate to FIT was 55.6% (697/1,254). In the multivariable logistic regression analysis, patients aged 60-75 years (odds ratio (OR)=1.30; 95% confidence interval (CI): 1.02-1.66; p=0.03), religious belief (OR=2.04; 95% CI: 1.34-3.11; p<0.01), previous fecal occult blood test (OR=2.07; 95% CI: 1.55-2.76; p<0.01), and full/part-time working status (OR=0.66; 95% CI: 0.49-0.89; p<0.01) were independently associated with adherence to CRC screening.

CONCLUSION

The results of the present study highlight the importance of considering the labor aspects when implementing screening programs, suggesting that campaigns conducted in the workplace and repeated over the years may be more effective.

Decreasing colorectal cancer screening disparities: A culturally tailored patient navigation program for Hispanic patients

BACKGROUND

Colorectal cancer (CRC) is the second leading cause of cancer-related death in Hispanic patients. Screening colonoscopy has been shown to reduce the incidence and mortality of CRC. However, utilization among Hispanic patients and other minority groups is low. The objective of this study was to evaluate colonoscopy utilization among Hispanic patients with a culturally tailored patient navigation program (CTPNP) in place.

METHODS

A CTPNP was designed to meet the needs of the authors' Hispanic patient population and their health care system characteristics. A CTPNP protocol was created, and a Spanish-speaking navigator/coordinator was hired. Enrolled patients received a Spanish-language introductory letter, an initial phone call for patient education, and follow-up calls to ensure that all potential barriers to colonoscopy were overcome. Colonoscopy completion (CC), colonoscopy cancellation (CN), and colonoscopy no-show (NS) rates were recorded and compared with historical rates in Rhode Island.

RESULTS

Over a 28-month period, 773 patients were referred to the CTPNP, and 698 (53% female and 47% male) were enrolled in the program. The overall CC rate was 85% (n = 592) with no difference between males and females. The CN rate was 9% (n = 62), and the NS rate was 6% (n = 44). The most common reasons for CN and NS were cost and an inability to contact the patient after referral. Within the CC group, 43% (n = 254) of patients underwent polypectomy, and 1.3% (n = 8) required colectomy. Ninety percent (n = 530) of the CC group reported that they would not have completed colonoscopy without the CTPNP.

CONCLUSIONS

Implementation of a CTPNP is an effective intervention to improve the CC rate and eliminate the historical gender gap in utilization among Hispanic patients.

Bridging the Gap: Patient Navigation Increases Colonoscopy Follow-up After Abnormal FIT

INTRODUCTION

Recent studies indicate low rates of follow-up colonoscopy after abnormal fecal immunochemical testing (FIT) within safety net health systems. A patient navigation (PN) program is an evidence-based strategy that has been shown to improve colonoscopy completion in private and public healthcare settings. The aim of this study was to evaluate the effectiveness of a PN program to encourage follow-up colonoscopy after abnormal FIT within a large safety net hospital system.

METHODS

We established an enterprisewide PN program at 5 tertiary care hospitals within the Los Angeles County Department of Health Services system in 2018. The PN assisted adult patients aged 50-75 years with an abnormal FIT to a follow-up colonoscopy within 6 months. PN activities included initiating referral for and scheduling of colonoscopy, performing reminder phone calls to patient for their upcoming colonoscopy, and following up with patients who did not attend their colonoscopy. We assess the effectiveness of the PN intervention by comparing follow-up colonoscopy rates with a period before the intervention.

RESULTS

There were 2,531 patients with abnormal FIT results (n = 1,214 in 2017 and n = 1,317 in 2018). A majority were women (55% in 2017 vs 52% in 2018) with a mean age of 60 ± 6.2 years. From a previous mean of 163 days without PN in 2017, the mean time from abnormal FIT to colonoscopy with PN improved to 113 days in 2018. The frequency of colonoscopy completion with PN increased from 40.6% (n = 493) in 2017 to 46% (n = 600) in 2018.

DISCUSSION

After the introduction of the PN program, there was a significant increase in patients undergoing follow-up colonoscopy after abnormal FIT and patients were more likely to undergo colonoscopy within the recommended 6 months.

Colorectal cancer screening among Hispanics in the United States: Disparities, modalities, predictors, and regional variation

Hispanics represent the largest and one of the fastest growing minority populations in the U.S. and have lower survival from colorectal cancer (CRC) than non-Hispanic Whites (NHW). We aimed to examine screening modalities, predictors, and regional disparities among Hispanics and NHW in the U.S. by conducting a cross-sectional analysis of Hispanic participants age 50 to 75 from the 2016 Behavioral Risk Factor Surveillance System (BRFSS) survey. The primary outcome was self-reported CRC screening status. We used the Rao-Scott Chi-square test to compare screening rates and modalities in NHWs and Hispanics. We also used univariable and multivariable logistic regression to determine predictors of screening among Hispanics and calculated Hispanic-NHW screening rate differences for each U.S. state/territory as a measure of regional screening disparities. The screening rate was 53.4% for Hispanics (N = 12,395), compared to 70.4% for NHWs (N = 186,331) (p < 0.001). Among Hispanics, colonoscopy was most common (75.9%). Uninsured status (aOR = 0.51; 95% CI = 0.38-0.70) and limited access to medical care (aOR = 0.38; 95% CI = 0.29-0.49) predicted lack of screening. States/territories with the largest screening disparities were North Carolina (33.9%), Texas (28.3%), California (25.1%), and Nebraska (25.6%). Disparities were smallest in New York (2.6%), Indiana (3.1%), and Delaware (4.0%). In Ohio and Guam, Hispanics had higher screening rates than NHWs. In conclusion, Hispanics have lower CRC screening rates than NHWs across most U.S. states/territories; however, the disparity varies by region. Future efforts must address multi-level barriers to screening among Hispanics and target regions with low rates to improve CRC outcomes in this growing population.

The Effects of the Nurse Navigation Program in Promoting Colorectal Cancer Screening Behaviors: a Randomized Controlled Trial

Although screening programs are known and recommended for the early detection of colorectal cancer (CRC), the screening rates for the fecal occult blood test (FOBT) and colonoscopy are very low among adult individuals. Navigation programs, also known as individualized counseling, have recently begun to be used for increasing screening rates. The purpose of this study was to compare the efficacy of the Nurse Navigation Program versus usual care on CRC screening participation and movement in stage of adoption for CRC screening and to examine perceived benefits of and barriers to CRC screening. This study was designed in line with a pre- and posttest two-group methodology. A total of 110 participants (55 nurse-navigated and 55 non-navigated patients) were studied. Data were collected using the following three tools: a sociodemographic information form, the Harvard Colorectal Cancer Risk Assessment Tool, and Instruments to Measure Colorectal Cancer Screening Benefits and Barriers. Following the Nurse Navigation Program, the FOBT (82 and 84%, respectively) and colonoscopy completion rates (15 and 22%, respectively) were significantly higher in the nurse-navigated group than in the non-navigated group at 3 and 6 months follow-up. Following the program, the benefit perceptions of the nurse-navigated group about CRC screening were improved, and their barrier perceptions were reduced. The results showed that the Nurse Navigation Program had significant effects on CRC screening behavior and health-related beliefs concerning CRC screening. Further assessment of the Nurse Navigation Program in different groups should be performed to observe its effects.

Predicting Colonoscopy Screening Behavior and Future Screening Intentions for African Americans Older than 50 Years

African Americans experience a disproportionate burden of morbidity and mortality from colorectal cancer, which may be due to low adherence to screening recommendations. Previous studies have found relationships between decision-making factors and screening behavior, but few have looked at both cognitive and affective factors or within a specifically African American sample. To better understand determinants that drive screening behavior, this study examines affective, cognitive, and social variables as predictors of colonoscopy in an age-eligible African American population. Participants completed surveys assessing affective associations with colonoscopy, perceived benefits and barriers, self-efficacy, knowledge, fear of colonoscopy, perceived risk, and colorectal cancer worry and fear. Regression analysis was used to model decision-making constructs as predictors of screening behavior/intentions. Affective, cognitive, and health care experience variables predicted colonoscopy completion and intentions. Provider-level factors and previous cancer screenings predicted prior screening only, but not intentions. Affective and cognitive components of perceived risk were associated with decreased likelihood of colonoscopy behavior, but increased likelihood of colonoscopy intentions. These findings suggest that colonoscopy decision making involves a complex array of both cognitive and affective determinants. This work extends our knowledge of colorectal cancer screening decision making by evaluating the effects of these multiple determinants on screening behavior in an African American sample. Future work exploring the interplay of affect and cognitions as influences on colonoscopy decision making and how health care experiences may moderate this effect is needed to develop effective intervention approaches and reduce screening disparities.

Utilization of Colorectal Cancer Screening among Saudi Elderly Population: A Study from the Saudi National Survey for Elderly Health

Objective: The goal of this study was to measure colorectal cancer screening (CRCS) utilization in Saudi Arabia ’s elderly population and to assess the factors associated with CRCS. Methods: The Saudi National Survey for Elderly Health was used to examine CRCS utilization. It is a nationally representative population-based cross-sectional survey that was conducted between 2006-2007. Utilization of CRCS was defined as any colonoscopy during the last five years or fecal occult blood test (FOBT) during the twelve months before the interview. Multivariable logistic regression was used to assess patients’ demographics, co-morbidities, number of visits to primary health clinics, and hospital availability and accessibility impact on CRCS. Results: The prevalence of CRCS utilization among Saudi elderly population was 5.64%. The fecal occult blood test was done in 4.4% of subjects while scope use was performed in 0.55%. In addition, 0.69% of patients have gone through both FOBT and scope use. Having blood in stools (OR=2.80; 95%CI: 1.3-6.00), Self-drivers (OR= 2.52) private driver (OR=2.1; 95%CI: 1.15-3.7) having 4 or more visits to primary care centers 1.81 (95%CI: 1.14-2.86) were positively associated with CRCS utilization. On the other hand, being single was negatively associated with CRCS utilization. Conclusion: In this nationally representative sample CRCS prevalence was very low. According to our findings and in the context of the burden of colorectal cancer on the population, we recommend developing national evidence-based policies and programs that take in consideration easiness of transportation and the availability of primary care centers near to Saudi elderly population.

Cervical Cancer Screening Barriers and Risk Factor Knowledge Among Uninsured Women

A steady decline in cervical cancer incidence and mortality in the United States has been attributed to increased uptake of cervical cancer screening tests such as Papanicolau (Pap) tests. However, disparities in Pap test compliance exist, and may be due in part to perceived barriers or lack of knowledge about risk factors for cervical cancer. This study aimed to assess correlates of cervical cancer risk factor knowledge and examine socio-demographic predictors of self-reported barriers to screening among a group of low-income uninsured women. Survey and procedure data from 433 women, who received grant-funded cervical cancer screenings over a span of 33 months, were examined for this project. Data included demographics, knowledge of risk factors, and agreement on potential barriers to screening. Descriptive analysis showed significant correlation between educational attainment and knowledge of risk factors (r = 0.1381, P < 0.01). Multivariate analyses revealed that compared to Whites, Hispanics had increased odds of identifying fear of finding cancer (OR 1.56, 95% CI 1.00–2.43), language barriers (OR 4.72, 95% CI 2.62–8.50), and male physicians (OR 2.16, 95% CI 1.32–3.55) as barriers. Hispanics (OR 1.99, 95% CI 1.16–3.44) and Blacks (OR 2.06, 95% CI 1.15–3.68) had a two-fold increase in odds of agreeing that lack of knowledge was a barrier. Identified barriers varied with age, marital status and previous screening. Programs aimed at conducting free or subsidized screenings for medically underserved women should include culturally relevant education and patient care in order to reduce barriers and improve screening compliance for safety-net populations.

A statewide program providing colorectal cancer screening to the uninsured of South Carolina

BACKGROUND

Cancer screening rates are lowest in those without insurance or a regular provider. Since 2008, the Colorectal Cancer Prevention Network (CCPN) has provided open access colonoscopy to uninsured residents of South Carolina through established, statewide partnerships and patient navigation. Herein, we describe the structure, implementation, and clinical outcomes of this program.

METHODS

The CCPN provides access to colonoscopy screening at no cost to uninsured, asymptomatic patients aged 50-64 years (African Americans age 45-64 years are eligible) who live at or below 150% of the poverty line and seek medical care in free medical clinics, federally qualified health centers, or hospital-based indigent practices in South Carolina. Screening is performed by board-certified gastroenterologists. Descriptive statistics and regression analysis are used to describe the population screened, and to assess compliance rates and colonoscopy quality metrics.

RESULTS

Out of >4000 patients referred to the program, 1854 were deemed eligible, 1144 attended an in-person navigation visit, and 1030 completed a colonoscopy; 909 were included in the final sample. Nearly 90% of participants exhibited good-to-excellent bowel preparation. An overall cecal intubation rate of 99% was measured. The polyp detection rate and adenoma detection rate were 63% and 36%, respectively, with male sex and urban residence positively associated with adenoma detection. Over 13% of participants had an advanced polyp, and 1% had a cancer diagnosis or surgical intervention.

CONCLUSION

The CCPN program is characterized by strong collaboration with clinicians statewide, low no-show rates, and high colonoscopy quality. Future work will assess the effectiveness of the navigation approach and will explore the mechanisms driving higher adenoma detection in urban participants.

Colorectal cancer screening at US community health centers: Examination of sociodemographic disparities and association with patient-provider communication

BACKGROUND

Colorectal cancer (CRC) screening rates are low among underserved populations. High-quality patient-physician communication potentially influences patients' willingness to undergo CRC screening. Community health centers (HCs) provide comprehensive primary health care to underserved populations. This study's objectives were to ascertain national CRC screening rates and to explore the relations between sociodemographic characteristics and patient-provider communication on the receipt of CRC screening among HC patients.

METHODS

Using 2014 Health Center Patient Survey data, bivariate and multivariate analyses examined the association of sociodemographic variables (sex, race/ethnicity, age, geography, preferred language, household income, insurance, and employment status) and patient-provider communication with the receipt of CRC screening.

RESULTS

Patients between the ages of 65 and 75 years (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.33-4.64) and patients not in the labor force (aOR, 2.32; 95% CI, 1.37-3.94) had higher odds of receiving CRC screening, whereas patients who were uninsured (aOR, 0.33; 95% CI, 0.18-0.61) and patients who were non-English-speaking (aOR, 0.42; 95% CI, 0.18-0.99) had lower odds. Patient-provider communication was not associated with the receipt of CRC screening.

CONCLUSIONS

The CRC screening rate for HC patients was 57.9%, whereas the rate was 65.1% according to the 2012 Behavioral Risk Factor Surveillance System and 58.2% according to the 2013 National Health Interview Survey. The high ratings of patient-provider communication, regardless of the screening status, suggest strides toward a patient-centered medical home practice transformation that will assist in a positive patient experience. Addressing the lack of insurance, making culturally and linguistically appropriate patient education materials available, and training clinicians and care teams in cultural competency are critical for increasing future CRC screening rates.
