Screening for colorectal cancer: the role of the primary care physician

Colon Cancer General Knowledge, Attitude and Awareness Channels: A Cross-Sectional Study

Background

Colon cancer is one of the most widespread cancers in Jordan. Screening of colon cancer aids in reducing its incidence and mortality rates. Awareness of colon cancer and its screening tools has a fundamental role in increasing screening participation. The information about Jordanians' awareness of colon cancer screening is inadequate.

Objective

This study aims to assess the Jordanian population's level of awareness about colon cancer, including basic knowledge, screening tools, attitudes toward early screening, and preferred methods for spreading awareness.

Methods

This is an analytical cross-sectional study. The study was conducted using both online and paper-based validated, and reliable questionnaires which were distributed throughout the entire community. Knowledge scores (KS range -10 to +10) and attitude scores (AS range -8 to +8) were calculated. Univariate analysis and logistic regression model were carried out. The nominal-by-nominal strength was also calculated.

Results

Information was collected from 1050 participants aged 18 to 70 years. with 63.6% being female responders. Participants with negative knowledge scores ''KS ≤ zero" were greater than good knowledge scores ''KS > 4 out of 10" (25.8% vs 11.4%). age, gender, insurance, working in the medical field, education, monthly income, smoking, and family history of cancer showed statistically significant associations with KS (p < 0.005, Cramer's V > 0.1). The strongest predictor for KS was the level of education (the postgraduate group showed OR = 4.64, p = 0.001, 95% CI = 1.96-11.0). Most participants (87.6%) had a positive attitude toward screening (AS ≥ 1). There were no associations between knowledge and attitude scores (p > 0.05). Unlike newspapers, social media was perceived as the most effective (70%) way to education.

Conclusion

One-quarter of the population is in crucial need for proper education, especially among young groups. This study forms a good basis and provides a solid foundation for health authorities to implement the necessary measures to address this issue.

Patient adherence to surveillance colonoscopy after endoscopic resection of colorectal polyps and factors associated with loss to follow-up

Background and study aims

Post-polypectomy surveillance colonoscopy (SC) plays an integral role in efforts to reduce colorectal cancer risk, but its effectiveness is invariably dependent on patient compliance. This study aimed to evaluate patient adherence to SC after endoscopic resection (ER) of polyps ≥ 20 mm and identify potential barriers associated with loss to follow-up.

Patients and methods

This was a single-center retrospective study evaluating adherence to SC after ER of polyps ≥ 20 mm between April 2018 to December 2021. Adherence to SC was defined as the proportion of patients who underwent follow-up colonoscopy. Multivariate logistic regression was performed to identify factors associated with loss to follow-up.

Results

A total of 959 patients (mean age 67 years; 47.9% women) underwent endoscopic resection of colorectal polyps ≥ 20 mm (mean size 33.2 ± 13.7 mm). Nearly half of the patients (n = 478; 49.8%) were lost to follow-up. On multivariate analysis, factors associated with a higher likelihood of SC non-adherence were: lack of a primary care physician (odds ratio [OR] 1.7;95% confidence interval [CI] 1.3- 2.3; P < 0.05), American Society of Anesthesiologists grade 3 or 4 (OR 1.4; 95% CI 1.1-1.9; P < 0.05), residence > 60 miles from the endoscopy suite (OR 1.6; 95% CI 1.2-2.3; P = 0.02), being referred by a physician outside of our healthcare system (OR 1.4; 95% CI 1.1-1.8; P = 0.01), and lack of written follow-up recommendations on the colonoscopy report (OR 3.6; 95% CI 1.4-10.2; P = 0.01).

Conclusions

Nearly half of patients undergoing ER of colorectal polyps ≥ 20 mm are lost to follow-up. We identified several patient- and healthcare-related factors as barriers to SC adherence. Strategies to address these issues and targeting of high-risk populations are urgently needed to enhance SC programs.

Current Progress in Clinical Research in Secondary Prevention and Early Detection of Colorectal Cancer

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths globally. The risk of disease increases with age, as most CRC patients are over 50 years old. Due to the progressive aging of societies in high-income countries, the problem of CRC will increase. This makes the development of new early detection methods and the implementation of effective screening programs crucial. Key areas of focus include raising population awareness about the importance of screening, educating high-risk populations, and improving and developing early diagnostic methods. The primary goal of this review is to provide a concise overview of recent trends and progress in CRC secondary prevention based on available information from clinical trials.

Explaining the Correlates of the Multi-Theory Model (MTM) of Health Behavior Change in Visual (Structural) Colorectal Cancer Screening Examinations

Colorectal cancer (CRC) ranks third in terms of global cancer prevalence and is the second most common cause of cancer-related mortality. Although CRC rates are decreasing in the United States, inequalities still exist despite the effectiveness of invasive screening methods, such as colonoscopy, flexible sigmoidoscopy, and computed tomography (CT) colonography in detecting colorectal cancer. Many current interventions promoting CRC screening do not utilize a modern theory-based approach, which has led to the low utilization of these screening methods. This cross-sectional study aims to address the lack of theory-based treatments for promoting visual CRC screening examinations by applying the multi-theory model (MTM) of health behavior change to explicate the health-related factors for individuals to seek visual colorectal cancer screening examinations for CRC screening. A 57-item validated questionnaire assessing MTM constructs and CRC screening was administered online. The survey questionnaire was administered to a sample of 640 adults from the United States. The participants were between the ages of 45 and 75 years. Hierarchical multiple regression was used to assess the relationship between MTM constructs with the initiation and sustenance of CRC screening behaviors. Out of the total participants in this nationwide sample, 71.4% (n = 457) reported that they had undergone a visual CRC screening examination. MTM subscales, specifically participatory dialogue, changes in the physical environment along with age, recommendation for CRC screening from a healthcare provider, and previous experience with colonoscopy, were found to be significant factors in predicting the initiation of visual CRC screening behavior. These factors accounted for 22% of the variation in initiation among this group (R2 = 0.222, F = 3.521, p < 0.001). The MTM can be a valuable framework for designing educational media, information media, social media platforms, and clinical interventions to promote visual colorectal cancer screening examinations.

Barriers and Facilitators to Colorectal Cancer Screening Among Health Fair Attendees in Utah

BACKGROUND

Colorectal cancer (CRC) screening uptake remains suboptimal despite the importance and effectiveness of various testing options. The purpose of our study was to identify barriers and facilitators to CRC screening in a community-based sample in Salt Lake County, Utah to inform future efforts to develop effective interventions to increase CRC screening.

METHODS

This study enrolled adults eligible for CRC screening at 6 community health events. Participants completed targeted questionnaires based on whether they had discussed screening with a provider and whether they had received screening. We identified participant-reported barriers to CRC screening using descriptive analysis. Univariate and multivariate analyses were used to identify participant characteristics associated with receipt of screening.

RESULTS

Of the 117 participants who completed the questionnaires, 43.6% were 50 to 60 years old, 36.8% identified as white, and 51.3% identified as non-Hispanic. The most common barrier to colonoscopy was the need for extensive bowel preparation (30.8%). For stool tests, common barriers included handling stool (20.5%) and not understanding how to do the test (20.5%). For virtual colonoscopy, barriers included the need for extensive bowel preparation (21.4%) and cost (21.4%). Most participants (67.5%) believed that they should know about all CRC screening options available, and their importance. The majority of participants (68.4%) preferred to learn about CRC screening from their doctor or healthcare provider. Younger age was associated with non-screening.

CONCLUSION

We observed that study participants faced procedural barriers to complete CRC screening and preferred to learn about CRC screening options through their providers. Younger age groups were less likely to receive screening within our study sample. Future, targeted interventions to increase CRC screening should focus on increasing the awareness of the importance of CRC screening and educating patients on the various screening options available and their benefits, especially as they pertain to less invasive tests and targeting younger individuals.

Association of county-level provider density and social vulnerability with colorectal cancer-related mortality

BACKGROUND

Health care providers play a crucial role in increasing overall awareness, screening, and treatment of cancer, leading to reduced cancer mortality. We sought to characterize the impact of provider density on colorectal cancer population-level mortality.

METHODS

County-level provider data, obtained from the Area Health Resource File between 2016 and 2018, were used to calculate provider density per county. These data were merged with county-level colorectal cancer mortality 2016-2020 data from the Centers for Disease Control and Prevention. Multivariable regression was performed to define the association between provider density and colorectal cancer mortality.

RESULTS

Among 2,863 counties included in the analytic cohort, 1,132 (39.5%) and 1,731 (60.5%) counties were categorized as urban and rural, respectively. The colorectal cancer-related crude mortality rate was higher in counties with low provider density versus counties with moderate or high provider density (low = 22.9, moderate = 21.6, high = 19.3 per 100,000 individuals; P < .001). On multivariable analysis, the odds of colorectal cancer mortality were lower in counties with moderate and high provider density versus counties with low provider density (moderate odds ratio 0.97, 95% confidence interval 0.94-0.99; high odds ratio 0.88, 95% confidence interval 0.86-0.91). High provider density remained associated with a lower likelihood of colorectal cancer mortality independent of social vulnerability index (low social vulnerability index and high provider density: odds ratio 0.85, 95% confidence interval 0.81-0.89; high social vulnerability index and high provider density: odds ratio 0.93, 95% confidence interval 0.89-0.98).

CONCLUSION

Regardless of social vulnerability index, high county-level provider density was associated with lower colorectal cancer-related mortality. Efforts to increase access to health care providers may improve health care equity, as well as long-term cancer outcomes.

"Shared decision-making" for prostate cancer screening: Is it a marker of quality preventative healthcare?

BACKGROUND

"Shared decision-making" (SDM) is a cornerstone of prostate cancer (PCa) screening guidelines due to tradeoffs between clinical benefits and concerns for over-diagnosis and over-treatment. SDM requires effort by primary-care-providers (PCP) in an often busy clinical setting to understand patient preferences with the backdrop of patient risk factors. We hypothesized that SDM for PCa screening, given its prominence in guidelines and practical challenges, may be associated with quality preventative healthcare in terms of other appropriate cancer screening and encouragement of other preventative health behaviors.

METHODS

From the 2020 Behavioral Risk Factor Surveillance Survey, 50-75 year old men who underwent PSA screening were assessed for their participation in SDM, PCa and colorectal cancer (CRC) screening, and other preventative health behaviors, like vaccination, exercise, and smoking status. Adjusted odds ratio of likelihood of PSA testing as a function of SDM was calculated. Likelihoods of SDM and PSA testing as a function of preventative health behaviors were also calculated.

RESULTS

Screening rates were 62 % for PCa and 88 % for CRC. Rates of SDM were 39.1 % in those with PSA screening, and 16.2 % in those without. Odds of PSA screening were higher when SDM was present (AOR = 2.68). History of colonoscopy was associated with higher odds of SDM (AOR = 1.16) and PSA testing (AOR = 1.94). Health behaviors, like regular exercise, were associated with increased odds of SDM (AOR = 1.14) and PSA testing (AOR = 1.28). History of flu vaccination (AOR = 1.29) and pneumonia vaccination (AOR = 1.19) were associated with higher odds of SDM. Those who received the flu vaccine were also more likely to have PSA testing (AOR = 1.36). Smoking was negatively associated with SDM (AOR = 0.86) and PSA testing (AOR = 0.93). Older age was associated with higher rates of PSA screening (AOR = 1.03, CI = 1.03-1.03). Black men were more likely than white men to have SDM (AOR = 1.6, CI = 1.59 - 1.6) and decreased odds of PSA testing (AOR = 0.94, CI = 0.94 - 0.95).

CONCLUSIONS

SDM was associated with higher odds of PSA screening, CRC screening, and other appropriate preventative health behaviors. Racial disparities exist in both SDM and PSA screening usage. SDM may be a trackable metric that can lead to wider preference-sensitive care and improved preventative care.

Focusing on colorectal cancer in young adults (Review)

Colorectal cancer (CRC) ranks as the third leading cause of cancer-related mortality worldwide. Recent years have witnessed an increase in the incidence of CRC among adults <50 years old on a global scale. The increased incidence is associated with several modifiable risk factors, including obesity, type II diabetes, physical inactivity and frequent antibiotic use. In younger individuals, haematochezia and abdominal pain are the most common symptoms, predominantly affecting the left-side colon. While certain cases of early-onset CRC (eoCRC) are associated with a genetic predisposition, the majority result from sporadic mutations in the genes APC, KRAS, BRAF and TP53, which trigger uncontrolled cell proliferation and tumour formation. Colorectal carcinogenesis involves three major pathways: The chromosomal instability (CIN), microsatellite instability and CpG island methylator phenotype pathways. Dysregulation of the CIN pathway accounts for 85% of sporadic cases of eoCRC. Notably, eoCRC exhibits a distinctive molecular profile, characterized by a decreased prevalence of BRAF mutations, an increased prevalence of KRAS mutations and LINE-1 hypomethylation, and involvement of the Microsatellite and Chromosomal Stable pathway. Prevention strategies for eoCRC primarily centre on lifestyle modifications and the development of screening programs targeting younger populations. Further exploration into the molecular mechanisms involved in the identification of novel risk factors associated with eoCRC is imperative. These efforts, in conjunction with the development of specific screening strategies, hold the potential to reduce morbidity and mortality in the future.

Disparities in Late-Stage Breast and Colorectal Cancer Diagnosis Among Hispanic, Non-Hispanic White, and Non-Hispanic Black Patients: a Retrospective Cohort Study of Texas Medicare Beneficiaries

BACKGROUND

Disparities in late-stage breast or colorectal cancer diagnosis in younger populations are associated with social determinants of health (SDOH; education, poverty, housing, employment). We hypothesized that, in older Medicare beneficiaries, disparities in late-stage cancer diagnosis between Hispanic, non-Hispanic Black (NHB), and non-Hispanic White (NHW) patients would be associated with SDOH, comorbidities, and primary care physician (PCP) access.

METHODS

We analyzed 2005-2017 Texas Cancer Registry data linked with Medicare data for patients aged ≥ 66 (n = 86,501). Variables included age at diagnosis, sex, comorbidities, poverty level, education, PCP, and relevant cancer screening within 1 year.

RESULTS

For breast cancer in women (Hispanic, n = 6380; NHW, n = 39,225; NHB, n = 4055), a fully adjusted model showed significantly higher odds of late-stage cancer diagnosis only in NHB patients (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.01-1.22) compared with NHW; adjustment for comorbidities and SDOH partially decreased the odds of late-stage diagnosis relative to NHWs. Interaction terms between race-ethnicity and poverty were not significant. For colorectal cancer, a fully adjusted multivariate model showed significantly higher odds of late-stage diagnosis only among NHBs (n = 3318, OR 1.29, 95% CI 1.19-1.40) relative to NHWs (n = 27,470); adjustment for SDOH partially decreased the odds of late-stage diagnosis in NHB patients. Interaction terms between race-ethnicity and poverty were not significant.

CONCLUSION

Racial disparities in late-stage breast and colorectal cancer diagnoses remain after adjustment for SDOH and clinically relevant factors, underscoring the need to optimize access to screening and timely cancer treatment in racial/ethnic minorities.

Social Determinants of Health in Imaging-based Cancer Screening: A Case-based Primer with Strategies for Care Improvement

Health disparities, preventable differences in the burden of disease and disease outcomes often experienced by socially disadvantaged populations, can be found in nearly all areas of radiology, including emergency radiology, neuroradiology, nuclear medicine, image-guided interventions, and imaging-based cancer screening. Disparities in imaging-based cancer screening are especially noteworthy given the far-reaching population health impact. The social determinants of health (SDoH) play an important role in disparities in cancer screening and outcomes. Through improved understanding of how SDoH can drive differences in health outcomes in radiology, radiologists can effectively provide patient-centered, high-quality, and equitable care. Radiologists and radiology practices can become active partners in efforts to assist patients along their imaging journey and overcome existing barriers to equitable cancer screening care for traditionally marginalized populations. As radiology exists at the intersection of diagnostic imaging, image-guided diagnostic intervention, and image-guided treatment, radiologists are uniquely positioned to design these strategies. Cost-effective and socially conscious strategies that address barriers to equitable care can improve both public health and equitable health outcomes. Potential strategies include championing supportive health policy, reducing out-of-pocket costs, increasing price transparency, improving education and outreach efforts, ensuring that appropriate language translation services are available, providing individualized assistance with appointment scheduling, and offering transportation assistance and childcare. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

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.

Patients' Expectations and Preferences for the Organizational Conditions of the Colorectal Cancer Screening Programme in Poland: A Qualitative Analysis

(1) Background: Colorectal cancer (CRC) is a serious health problem in Poland as well as many European Union countries. The study aimed to describe factors that, from the patient's perspective, could increase the attendance rate and regularity of participation in the colorectal cancer screening programme (SP); (2) Methods: The qualitative approach was applied. The study involved six focus interviews conducted with 24 respondents (12 women and 12 men) aged 40-49, who had at least one first-degree family member diagnosed with CRC and persons aged 50-65, living in five selected voivodships (provinces) of Poland. The collected data were thematically coded. Further, a comparative analysis was conducted, and aggregated statements were formulated; (3) Results: The inclusion of primary care clinics within the CRC SP organization was reported as a key factor in improving the attendance rate and regularity of patient participation in the programme. Particularly important factors included an invitation in the form of a personal letter or a phone call made by staff from primary care clinics; (4) Conclusions: Patients were confirmed to have clear expectations and preferences for the organizational conditions of the CRC SP. Preferences nature allows them to be treated as one of the potential criteria for selecting critical parameters of CRC SPs.

The effect of physician density on colorectal cancer stage at diagnosis: causal inference methods for spatial data applied on regional-level data

BACKGROUND

The early detection of colorectal cancer (CRC) through regular screening decreases its incidence and mortality rates and improves survival rates. Norway has an extremely high percentage of CRC cases diagnosed at late stages, with large variations across municipalities and hospital catchment areas. This study examined whether the availability of physicians related to CRC primary diagnosis and preoperative investigations, or physician density, contributes to the observed geographical differences in late-stage incidence rates.

METHOD

Municipality-level data on CRC stage at diagnosis were obtained from the Cancer Registry of Norway for the period 2012-2020. Physician density was calculated as the number of physicians related to CRC investigations, general practitioners (GPs) and specialists per 10,000 people, using physician counts per municipality and hospital areas from Statistics Norway. The relationship was examined using a novel causal inference method for spatial data-neighbourhood adjustment method via spatial smoothing (NA approach)-which allowed for studying the region-level effect of physician supply on CRC outcome by using spatially referenced data and still providing causal relationships.

RESULTS

According to the NA approach, an increase in one general practitioner per 10,000 people will result in a 3.6% (CI -0.064 to -0.008) decrease in late-stage CRC rates. For specialists, there was no evidence of a significant correlation with late-stage CRC distribution, while for both groups, GPs and specialists combined, an increase of 1 physician per 10,000 people would be equal to an average decrease in late-stage incidence rates by 2.79% (CI -0.055 to -0.001).

CONCLUSION

The study confirmed previous findings that an increase in GP supply will significantly improve CRC outcomes. In contrast to previous research, this study identified the importance of accessibility to both groups of physicians-GPs and specialists. If GPs encounter insufficient workforces in hospitals and long delays in colonoscopy scheduling, they will less often recommend colonoscopy examinations to patients. This study also highlighted the efficiency of the novel methodology for spatially referenced data, which allowed us to study the effect of physician density on cancer outcomes within a causal inference framework.

Colorectal Cancer Screening Knowledge and Practices Among Practicing Obstetrician-Gynecologists and Residents

BACKGROUND

Colorectal cancer (CRC) is the second leading cause of cancer death in the US, the third most diagnosed cancer in women, and the second leading cause of cancer death in women. The aims of our study are to (1) investigate knowledge of and adherence to CRC screening guidelines by obstetrician-gynecologists (Ob/Gyns) and (2) assess whether this knowledge/adherence vary by demographic and practice characteristics.

METHODS

An anonymous cross-sectional survey was distributed to a convenience sample of 142 practicing Obs/Gyns drawn from National Medical Association section members/conference attendees and hospital Ob/Gyn department members.

RESULTS

Most respondents (80.3%) viewed colorectal screening within the scope of Ob/Gyn practice, and 71.8% used the American College of Obstetricians and Gynecologists guidelines for screening. Most respondents were knowledgeable regarding CRC screening but not in all areas. On average they only identified half of the 10 risk factors listed and only one-quarter correctly identified the age when screening can stop. Residents were somewhat more knowledgeable about screening guidelines and risk factors than attendings. More than half of respondents (57.8%) reported always initiating CRC screening for the appropriate age and risk factors. Respondents identified education and awareness (56.3%) and patients' unwillingness to undergo an invasive procedure (75.4%) as barriers to screening.

CONCLUSIONS

Knowledge regarding CRC screening was less than optimal and differed by attending/resident status. Greater emphasis should be placed on CRC screening and guidelines training for primary care providers like Ob/Gyns. Some of this could be accomplished through maintenance of certification and continued integration into residency education.

Facilitators and barriers to colorectal cancer screening using the immunochemical faecal occult blood test among an average-risk population in semi-rural Malaysia: A qualitative study

BACKGROUND

Colorectal cancer (CRC) incidence in Malaysia is increasing, and most CRC patients are diagnosed at a late stage. This study investigated participant awareness of CRC and their perceptions and views about CRC screening, barriers, benefits, and facilitators towards CRC screening participation as well as health-seeking behaviour and the use of preventative health services.

METHOD

Eleven focus group discussions (FGDs) were conducted with a purposive sample of 89 participants aged > 50 from the major ethnic groups in the Segamat District, Johor State. FGDs were audiotaped, transcribed verbatim, and translated into English. Data were analysed using thematic analysis.

RESULTS

We identified trust in doctors as a key reason for whether or not to seek health care. Generally, the participants had low awareness of CRC sign/symptoms and screening. Emotional and logistic concerns about sending a stool sample to a clinic emerged as the main barriers to screening. Simplified illustrated instructions about stool collection in Malay, Chinese and Tamil, free screening at health clinics and reminders to complete the iFOBT test were perceived to facilitate engagement in screening, and posited as strategies that were likely to increase iFOBT uptake.

CONCLUSION

Primary care physicians play a crucial role in terms of reducing patient's misperceptions, recommending screening to patients, enhancing attendance, and improving uptake of CRC screening. There is a need for further research to investigate ways in which to reduce identified barriers and implement and test potential facilitative strategies as well as examine adherence by doctors to clinical guidelines about CRC screening.

Clinical Cancer and Direct-to-Consumer Genetic Test Result-Sharing Behavior: Findings from HINTS 2020

INTRODUCTION

Sharing genetic test results with different stakeholders such as family members, healthcare providers and genetic counselors (HCP/GCs), spouses/partners, and friends is a health behavior of clinical importance in genomic medicine.

METHODS

Using nationally representative population-based data collected from the Health Information National Trends Survey (HINTS 5, cycle 4), we identified the prevalence and factors associated with genetic test result-sharing behavior for high-risk cancer tests, genetic health risk tests, and ancestry tests within four groups: HCP/GCs, first-degree relatives (FDRs), spouse/partner, and friend/other.

RESULTS

Overall, 68.4% of those who underwent high-risk cancer genetic testing shared their results with FDRs, whereas 89.9% shared with HCP/GCs. In adjusted multivariable analyses, women were nine times more likely than men to share (p = 0.006), and those with a personal history of cancer were less likely to share with HCP/GCs (OR = 0.025, p ≤ 0.001). Of those tested for genetic health risk, 66.5% shared with HCP/GCs, 38.7% with FDRs, 66.6% with a spouse/partner, 12.8% with a friend, and 14.1% did not share results with anyone. Of those who underwent ancestry testing, very few shared results with HCP/GCs (2.6%), whereas modest sharing was reported with FDRs, spouses/partners, and friends.

DISCUSSION

These data add empirical evidence about the population prevalence of genetic information sharing and serve as a metric for public engagement with genetic testing.

Racial Disparities in Colorectal Cancer Care for Black Patients: Barriers and Solutions

Racial disparities in colorectal cancer for Black patients have led to a significant mortality difference when compared to White patients, a gap which has remained to this day. These differences have been linked to poorer quality insurance and socioeconomic status in addition to lower access to high-quality health care resources, which are emblematic of systemic racial inequities. Disparities impact nearly every point along the colorectal cancer care continuum and include barriers to screening, surgical care, oncologic care, and surveillance. These critical faults are the driving forces behind the mortality difference Black patients face. Health care systems should strive to correct these disparities through both cultural competency at the provider level and public policy change at the national level.

The Impact of Primary Care Physicians on the Surgical Presentation and Outcomes of Colorectal Cancer in Vulnerable Populations

BACKGROUND

Multiple socioeconomic and clinical factors have been implicated in the health disparities that exist amongst vulnerable populations with colorectal cancer. Efforts have been directed toward addressing these factors to improve outcomes. We evaluate the impact of primary care physicians (PCP) on the surgical presentation and outcomes of colorectal cancer at a safety-net hospital.

METHODS

A retrospective chart review of 331 patients diagnosed with colorectal adenocarcinoma between 2014 and 2020 at a single-institution urban county medical center.

RESULTS

The cohort was predominantly male (59%) and Hispanic (52.1%). Thirty-two percent of patients had a PCP at time of diagnosis. Patients with PCPs compared to those without PCPs had significantly lower rates of acute presentation (perforation or obstruction) (17.0 vs 38.1%, P < .001), higher rates of surgical resection (83.0 vs 70.7%, P = .016), and were less likely to have metastatic disease at presentation (20.4 vs 33.5%, P = .02). Overall, having a PCP also improved probability of survival (HR 1.36, P < .04).

CONCLUSION

Having a PCP at the time of colorectal cancer diagnosis is associated with improved outcomes in a safety-net population, with significant differences in surgical presentation and resection.

Endoscopic resection of superficial bowel neoplasia: The unmet needs in the Egyptian practice

BACKGROUND

Management of superficial bowel neoplasia (SBN) in early stages is associated with better outcomes. The last few decades experienced a paradigm shift in the management of SBN with the introduction of advanced endoscopic resection techniques (ERTs). However, there are no clear data about the aspects of ERTs in Egypt despite the growing gastroenterology practice.

AIM

To investigate the knowledge, attitude, and practice of ERTs toward management of SBN among Egyptian practitioners and the suitability of the endoscopy units' infrastructures toward these techniques.

METHODS

An online 2-pages questionnaire was used. The first page comprised demographic data, and questions for all physicians, about the knowledge (11 questions) of and attitude (5 questions) toward ERTs as a therapeutic option for SBN. The second page investigated the practice of ERTs by endoscopists (6 questions) and the infrastructures of their endoscopy units (14 questions). The survey was disseminated through July 2021 and the data were collected in an excel sheet and later analyzed anonymously.

RESULTS

The complete responses were 833/2300 (36.2%). The majority of the participants were males (n = 560, 67.2%), middle-aged (n = 366, 43.9%), consultants (n = 464, 55.7%), gastroenterologists (n = 678, 81.4%), spending ≥ 15 years in practice (n = 368, 44.2%), and were working in university hospitals (n = 569, 68.3%). The majority correctly identified the definition of SBN (88.4%) and the terms polypectomy, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD) (92.1%, 90.2%, and 89.1% respectively). However, 26.9%, 43.2% and 49.5% did not recognize the clear indication of polypectomy, EMR, and ESD respectively. Although 68.1% of physicians are convinced about the ERTs for management of SBN; only 8.9% referred all candidate cases for ERTs. About 76.5% of endoscopists had formal training in the basic polypectomy techniques while formal training for EMR and ESD was encountered only in 31.9% and 7.2% respectively. About 71.6% and 88.4% of endoscopists did not perform EMR or ESD in the last one year. Consequently, the complication rate reported by endoscopists was limited to 18.1% (n = 103) of endoscopists. Only 25.8% of endoscopists feel confident in the management of ERTs-related complications and a half (49.9%) were not sure about their competency. Regarding the endoscopy units' infrastructures, only 4.2% of the centers had their endoscopes 100% armed with optical enhancements and 54.4% considered their institutions ready for managing ERTs-related complications. Only 18.3% (n = 104) of endoscopists treated their complicated cases surgically because the most frequent ERTs-related complications were procedural bleeding (26.7%), and perforations (17%).

CONCLUSION

A significant deficiency was reported in the knowledge and attitude of Egyptian practitioners caring for patients with SBN toward ERTs. The lack of trained endoscopists in both EMR and ESD in part is due to unsuitable infrastructures of many endoscopy units.

Endoscopic resection of superficial bowel neoplasia: The unmet needs in the Egyptian practice

BACKGROUND

Management of superficial bowel neoplasia (SBN) in early stages is associated with better outcomes. The last few decades experienced a paradigm shift in the management of SBN with the introduction of advanced endoscopic resection techniques (ERTs). However, there are no clear data about the aspects of ERTs in Egypt despite the growing gastroenterology practice.

AIM

To investigate the knowledge, attitude, and practice of ERTs toward management of SBN among Egyptian practitioners and the suitability of the endoscopy units’ infrastructures toward these techniques.

METHODS

An online 2-pages questionnaire was used. The first page comprised demographic data, and questions for all physicians, about the knowledge (11 questions) of and attitude (5 questions) toward ERTs as a therapeutic option for SBN. The second page investigated the practice of ERTs by endoscopists (6 questions) and the infrastructures of their endoscopy units (14 questions). The survey was disseminated through July 2021 and the data were collected in an excel sheet and later analyzed anonymously.

RESULTS

The complete responses were 833/2300 (36.2%). The majority of the participants were males (n = 560, 67.2%), middle-aged (n = 366, 43.9%), consultants (n = 464, 55.7%), gastroenterologists (n = 678, 81.4%), spending ≥ 15 years in practice (n = 368, 44.2%), and were working in university hospitals (n = 569, 68.3%). The majority correctly identified the definition of SBN (88.4%) and the terms polypectomy, endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD) (92.1%, 90.2%, and 89.1% respectively). However, 26.9%, 43.2% and 49.5% did not recognize the clear indication of polypectomy, EMR, and ESD respectively. Although 68.1% of physicians are convinced about the ERTs for management of SBN; only 8.9% referred all candidate cases for ERTs. About 76.5% of endoscopists had formal training in the basic polypectomy techniques while formal training for EMR and ESD was encountered only in 31.9% and 7.2% respectively. About 71.6% and 88.4% of endoscopists did not perform EMR or ESD in the last one year. Consequently, the complication rate reported by endoscopists was limited to 18.1% (n = 103) of endoscopists. Only 25.8% of endoscopists feel confident in the management of ERTs-related complications and a half (49.9%) were not sure about their competency. Regarding the endoscopy units’ infrastructures, only 4.2% of the centers had their endoscopes 100% armed with optical enhancements and 54.4% considered their institutions ready for managing ERTs-related complications. Only 18.3% (n = 104) of endoscopists treated their complicated cases surgically because the most frequent ERTs-related complications were procedural bleeding (26.7%), and perforations (17%).

CONCLUSION

A significant deficiency was reported in the knowledge and attitude of Egyptian practitioners caring for patients with SBN toward ERTs. The lack of trained endoscopists in both EMR and ESD in part is due to unsuitable infrastructures of many endoscopy units.

Gastrointestinal Cancer Prevention Policies: A Qualitative Systematic Review and Meta-Synthesis

This qualitative systematic review was conducted to summarize the policies for prevention of common gastrointestinal cancers worldwide. This study was conducted using PubMed, Web of Science, SCOPUS, and ProQuest databases. Two independent reviewers assessed included studies for methodological quality and extracted data by using standardized tools from Joanna Briggs Institute (JBI). Primary study findings were read and reread to identify the strategies or policies used in the studies for prevention of gastrointestinal cancers. The extracted findings were categorized on the basis of their similarity in meaning. These categories were then subjected to a meta-synthesis. The final synthesized findings were graded according to the ConQual approach for establishing confidence in the output of qualitative research synthesis. From the nine included studies in this review, 39 findings were extracted and based on their relevance in meaning were aggregated into 12 categories. Four synthesized findings were developed from these categories. We used World Health Organization report on 2000 for synthesizing the findings. The four synthesized findings were "service provision", "resource generation", "financing", and "stewardship". In order to reach a comprehensive evidence informed policy package for the prevention of gastrointestinal cancers, there should be a great communication among the interventions conducted directly on patients, health system infrastructures, and resources.

Mail-out bowel cancer screening: Identifying the behavioural stumbling blocks

OBJECTIVE

To describe the actions taken by recipients of mail-out faecal occult blood test (FOBT) kits and to identify the points at which progress towards kit completion typically stops. Differences according to gender, age, and screening intention were also examined.

METHODS

1599 people completed an online survey identifying the actions they took upon receiving an FOBT kit. Latent class analysis was conducted to identify latent subgroups of participants that reported similar actions. Differences between gender, age, and intention status were assessed using non-invariance testing.

RESULTS

Four latent subgroups of FOBT invitees were identified: those who complete and return their FOBT kit ('completers'); those who bring the kit into their house but go no further ('ignorers'); those who open the package and read the bowel cancer information materials but go no further ('readers'); and those who read the instructions but do not place the kit near the toilet and do not complete their FOBT kit ('leavers'). Non-completers who intended to use the kit were most likely to be in the 'leavers' class, while those who had no intention were most likely to be in the 'readers' class.

CONCLUSIONS

Distinct subgroups of non-responders exist among bowel cancer screening invitees, suggesting different behaviour change interventions are needed to facilitate participation. Some invitees, especially those with high participatory intention, are likely to benefit from prompts to take the kit into the toilet, while others, with little participatory intention, often read the invitation materials presenting an opportunity to intervene with health messages.

Screening Practices, Knowledge and Adherence Among Health Care Professionals at a Tertiary Care Hospital

Introduction

Screening, a routine procedure done on individuals with or without disease, results in the early detection of disease. The aim of this study was to assess healthcare professionals’ (HCPs) level of knowledge related to and the adherence to screening.

Methods

A survey was conducted in HCPs, using a self-administered questionnaire. Knowledge was defined based on the correct or incorrect responses to the questions. Adherence to screening was considered if a test was done at least once in the past one year.

Results

Of the 379 participants, 61% were nurses, 34% physicians, and 5% pharmacists. The majority 68.78% were female. The average age of pharmacists was 29.17±7.09, physicians 35.57±10.08, and nurses 35.46±8.63 years. The knowledge related to breast cancer screening ranged between 50% and 57% and of a Pap smear, 41–54%. 94% nurses and 90% pharmacists had recorded an incorrect response to the required age of colon cancer screening. The overall screening adherence to diabetes was 46%, hypertension 68%, liver profile 43%, lipid profile 50%, breast cancer 10.38%, Pap smear 26%, prostate cancer 33%, and colon cancer 2.37%. HCPs aged ≥45 years had good adherence to diabetes screening. Pharmacists (88%) had the highest level of adherence to hypertension screening. Female HCPs poorly adhered to breast 38% and cervical cancer 26% screening. Only a third 33% of males, aged > 50 years, were screened for prostate cancer. Among HCPs aged ≥50 years (n=32), only three were screened for colon cancer.

Conclusion

Despite the increased incidence of diabetes, breast and colon cancer in Saudi Arabia, HCPs displayed poor knowledge related to screening. The adherence to diabetes screening was good. However, HCPs in a high-risk group displayed poor adherence to screening, specifically for breast, cervical and colon cancer. The medical and cancer screening guidelines should be made available to all HCPs regardless of their specialty.

Impact of a colorectal cancer screening program implantation on delays and prognosis of non-screening detected colorectal cancer

BACKGROUND

The implementation of a colorectal cancer (CRC) screening programme may increase the awareness of Primary Care Physicians, reduce the diagnostic delay in CRC detected outside the scope of the screening programme and thus improve prognosis.

AIM

To determine the effect of implementation of a CRC screening programme on diagnostic delays and prognosis of CRC detected outside the scope of a screening programme.

METHODS

We performed a retrospective intervention study with a pre-post design. We identified 322 patients with incident and confirmed CRC in the pre-implantation cohort (June 2014 – May 2015) and 285 in the post-implantation cohort (June 2017 - May 2018) in the Cancer Registry detected outside the scope of a CRC screening programme. In each patient we calculated the different healthcare diagnostics delays: global, primary and secondary healthcare, referral and colonoscopy-related delays. In addition, we collected the initial healthcare that evaluated the patient, the home location (urban/rural), and the CRC stage at diagnosis. We determined the two-year survival and we performed a multivariate proportional hazard regression analysis to determine the variables associated with survival.

RESULTS

We did not detect any differences in the patient or CRC baseline-related variables. A total of 20.1% of patients was detected with metastatic disease. There was a significant increase in direct referral to colonoscopy from primary healthcare (25.5%, 35.8%; P = 0.04) in the post-implantation cohort. Diagnostic delay was reduced by 24 d (106.64 ± 148.84 days, 82.84 ± 109.31 d; P = 0.02) due to the reduction in secondary healthcare delay (46.01 ± 111.65 d; 29.20 ± 60.83 d; P = 0.02). However, we did not find any differences in CRC stage at diagnosis or in two-year survival (70.3%; P = 0.9). Variables independently associated with two-year risk of death were age (Hazard Ratio-HR: 1.06, 95%CI: 1.04-1.07), CRC stage (II HR: 2.17, 95%CI: 1.07-4.40; III HR: 3.07, 95%CI: 1.56-6.08; IV HR: 19.22, 95%CI: 9.86-37.44; unknown HR: 9.24, 95%CI: 4.27-19.99), initial healthcare consultation (secondary HR: 2.93, 95%CI: 1.01-8.55; emergency department HR: 2.06, 95%CI: 0.67-6.34), hospitalization during the diagnostic process (HR: 1.67, 95%CI: 1.17-2.38) and urban residence (HR: 1.44, 95%CI: 1.06-1.98).

CONCLUSION

Although implementation of a CRC screening programme can reduce diagnostic delays for CRC detected in symptomatic patients, this has no effect on CRC stage or survival.

Colorectal Cancer Screening Prevalence and Adherence for the Cancer Prevention Project of Philadelphia (CAP3) Participants Who Self-Identify as Black

INTRODUCTION

Colorectal cancer is the third leading cause of cancer-related deaths among Black men and women. While colorectal cancer screening (CRCS) reduces mortality, research assessing within race CRCS differences is lacking. This study assessed CRCS prevalence and adherence to national screening recommendations and the association of region of birth with CRCS adherence, within a diverse Black population.

METHODS

Data from age-eligible adults, 50-75 years, (N = 357) participating in an ongoing, cross-sectional study, was used to measure CRCS prevalence and adherence and region of birth (e.g., Caribbean-, African-, US-born). Prevalence and adherence were based on contemporaneous US Preventive Services Task Force guidelines. Descriptive statistics were calculated and adjusted prevalence and adherence proportions were calculated by region of birth. Adjusted logistic regression models were performed to assess the association between region of birth and overall CRCS and modality-specific adherence.

RESULTS

Respondents were 69.5% female, 43.3% married/living with partner, and 38.4% had <$25,000 annual income. Overall, 78.2% reported past CRCS; however, stool test had the lowest prevalence overall (34.6%). Caribbean (95.0%) and African immigrants (90.2%) had higher prevalence of overall CRCS compared to US-born Blacks (59.2%) (p-value <0.001). African immigrants were five times more likely to be adherent to overall CRCS compared to US-born Blacks (OR = 5.25, 95% CI 1.34-20.6). Immigrants had higher odds of being adherent to colonoscopy (Caribbean OR = 6.84, 95% CI 1.49-31.5; African OR = 7.14, 95% CI 1.27-40.3) compared to US-born Blacks.

CONCLUSIONS

While Caribbean and African immigrants have higher prevalence and adherence of CRCS when compared US-born Blacks, CRCS is still sub-optimal in the Black population. Efforts to increase CRCS, specifically stool testing, within the Black population are warranted, with targeted interventions geared towards US-born Blacks.

Recognising Colorectal Cancer in Primary Care

Colorectal cancer (CRC) is the third most common cancer worldwide. Primary care professionals can play an important role in both prevention and early detection of CRC. Most CRCs are attributed to modifiable lifestyle factors, which can be addressed within primary care, and promotion of population-based screening programmes can aid early cancer detection in asymptomatic patients. Primary care professionals have a vital role in clinically assessing patients presenting with symptoms that may indicate cancer, as most patients with CRC first present with symptoms. These assessments are often challenging—many of the symptoms of CRC are non-specific and commonly occur in patients presenting with non-malignant disease. The range of options for investigating symptomatic patients in primary care is rapidly growing. Simple tests, such as faecal immunochemical testing (FIT), are now being used to guide decisions around referral for more invasive tests, such as colonoscopy, while direct access to specialist investigations is also becoming more common. Clinical decision support tools (CDSTs) which calculate cancer risk based on symptomatology, patient characteristics and test results can provide an additional resource to guide decisions on further investigation. This article explores the challenges of CRC prevention and detection from the primary care perspective, discusses current evidence-based approaches for CRC detection used in primary care (with examples from UK guidelines), and highlights emerging research which may likely alter practice in the future.

Assessing Colorectal Cancer Screening Barriers in Rural Appalachia

OBJECTIVES

The age-appropriate colorectal cancer (CRC) screening rate in the rural Appalachian area is low compared with the national rate, which may account for the overall higher incidence of CRC in this area. The purpose of this study was to explore potential barriers to CRC screening in the West Virginia Appalachian area.

METHODS

A cross-sectional survey was designed to identify patient-reported barriers to CRC screening using the health belief model to assess their attitudes and behaviors. Autonomous paper-based surveys were randomly handed to individuals older than 50 years at various locations, including healthcare and nonhealthcare facilities. All of the responses were then categorized into two groups: the screened group and the unscreened group. Differences among both groups were statistically analyzed.

RESULTS

There were three main areas that significantly accounted for the discrepancies between the screened and unscreened groups: perceptions of discomfort from screening tests, psychological and behavior deterrents in CRC screening and diagnosis, and limited resources for accessing care, especially transportation. In particular, psychological and behavioral deterrents in CRC screening appeared to play a role in promoting aversion to CRC screening.

CONCLUSIONS

Lack of CRC screening awareness and knowledge may be responsible for fatalism regarding CRC and aversion to screening. Thus, multidisciplinary interventions that provide education about CRC screening, early intervention prognosis, and treatment options, as well as addressing systemic barriers to screening, such as assistance with scheduling, prep instructions, and transportation, can improve the screening rate in Appalachia and eventually lead to better outcomes through the early diagnosis of CRC.

Identifying an association between socio-demographic factors and breast cancer screening adherence in a federally qualified health centre sample in the United States. A retrospective, cross-sectional study

Federally Qualified Health Centres (FQHC) are community-based centres in the United States, intended to fill a gap in care for underserved populations, including Medicaid patients and the homeless. Because of the Affordable Care Act, passed into law in 2010, there was a 29% increase in Medicaid enrolees nationally. One service offered at FQHCs is breast cancer screening. Breast cancer screening has been shown to have the lowest adherence levels among low-income women and homeless women. As they serve patients with socio-economic barriers, FQHCs are a vital resource in ensuring access to such screening. This study aimed to identity an association between socio-demographic factors and breast cancer screening adherence in FQHC patients that included the homeless. This exploratory, cross-sectional, retrospective study looked at encounter level data from a FQHC in a major metropolitan (Chicago, IL) area from January 1st, 2017 through December 31st, 2018. Data were collected in January of 2019. This was a convenience sample. Association was tested through bivariate chi-square tests and multivariate logistic regression analysis, investigating the association between socio-demographic characteristics and compliance (Yes/No) for breast cancer screening. Results showed age (55-59; 65-69) and homeless status (doubling-up, transitional) showed a positive association with breast cancer screening, while insurance status (self-pay) had a negative association. Age, homeless status and insurance type were significantly associated with adherence. Demographic characteristics in the homeless population can be used to identify nonadherence.

Insurance type impacts the economic burden and survival of patients with newly diagnosed glioblastoma

OBJECTIVE

Glioblastoma (GBM) carries a high economic burden for patients and caregivers, much of which is associated with initial surgery. The authors investigated the impact of insurance status on the inpatient hospital costs of surgery for patients with GBM.

METHODS

The authors conducted a retrospective review of patients with GBM (2010-2015) undergoing their first resection at the University of California, San Francisco, and corresponding inpatient hospital costs.

RESULTS

Of 227 patients with GBM (median age 62 years, 37.9% females), 31 (13.7%) had Medicaid, 94 (41.4%) had Medicare, and 102 (44.9%) had private insurance. Medicaid patients had 30% higher overall hospital costs for surgery compared to non-Medicaid patients ($50,285 vs $38,779, p = 0.01). Medicaid patients had higher intensive care unit (ICU; p < 0.01), operating room (p < 0.03), imaging (p < 0.001), room and board (p < 0001), and pharmacy (p < 0.02) costs versus non-Medicaid patients. Medicaid patients had significantly longer overall and ICU lengths of stay (6.9 and 2.6 days) versus Medicare (4.0 and 1.5 days) and privately insured patients (3.9 and 1.8 days, p < 0.01). Medicaid patients had similar comorbidity rates to Medicare patients (67.8% vs 68.1%), and both groups had higher comorbidity rates than privately insured patients (37.3%, p < 0.0001). Only 67.7% of Medicaid patients had primary care providers (PCPs) versus 91.5% of Medicare and 86.3% of privately insured patients (p = 0.009) at the time of presentation. Tumor diameter at diagnosis was largest for Medicaid (4.7 cm) versus Medicare (4.1 cm) and privately insured patients (4.2 cm, p = 0.03). Preoperative (70 vs 90, p = 0.02) and postoperative (80 vs 90, p = 0.03) Karnofsky Performance Scale (KPS) scores were lowest for Medicaid versus non-Medicaid patients, while in subgroup analysis, postoperative KPS score was lowest for Medicaid patients (80, vs 90 for Medicare and 90 for private insurance; p = 0.03). Medicaid patients had significantly shorter median overall survival (10.7 months vs 12.8 months for Medicare and 15.8 months for private insurance; p = 0.02). Quality-adjusted life year (QALY) scores were 0.66 and 1.05 for Medicaid and non-Medicaid patients, respectively (p = 0.036). The incremental cost per QALY was $29,963 lower for the non-Medicaid cohort.

CONCLUSIONS

Patients with GBMs and Medicaid have higher surgical costs, longer lengths of stay, poorer survival, and lower QALY scores. This study indicates that these patients lack PCPs, have more comorbidities, and present later in the disease course with larger tumors; these factors may drive the poorer postoperative function and greater consumption of hospital resources that were identified. Given limited resources and rising healthcare costs, factors such as access to PCPs, equitable adjuvant therapy, and early screening/diagnosis of disease need to be improved in order to improve prognosis and reduce hospital costs for patients with GBM.

Identifying potential DNA methylation markers in early-stage colorectal Cancer

Colorectal cancer (CRC) is the second leading malignancy worldwide. Accurate screening is pivotal to early CRC detection, yet current screening modality involves invasive colonoscopy while non-invasive FIT tests have limited sensitivity. We applied a DNA methylation assay to identify biomarkers for early-stage CRC detection, risk stratification and precancerous lesion screening at tissue level. A model of biomarkers SFMBT2, ITGA4, THBD and ZNF304 showed 96.1% sensitivity and 87.0% specificity in CRC detection, with 100.0% sensitivity for advanced precancerous lesion and stage I CRC. Performances were further validated with TCGA data set, which showed a consistent AUC of 0.99 and exhibited specificity against other cancer types. KCNJ12, VAV3-AS1 and EVC were further identified for stage stratification (stage 0-I versus stage II-IV), with AUC of 0.87, 83.0% sensitivity and 71.2% specificity. Additionally, dual markers of NEUROD1 and FAM72C showed 83.2% sensitivity and 77.4% specificity in differing non-advanced precancerous lesions from inflammatory bowel diseases.

Self-reported screening practices of family physicians participating in the colorectal cancer screening program of the canton of Vaud: a cross-sectional study

Background

The organized colorectal cancer (CRC) screening program in the canton of Vaud, Switzerland offers citizens the choice of the faecal immunochemical test (FIT) or colonoscopy via a visit with a family physician (FP). Given the central role of FPs in the program, this study aimed to compare their self-reported preventive practices with the objectives of the program, namely to inform patients about CRC screening and present the choice of colonoscopy and FIT, and to identify factors associated with presenting a choice of tests.

Methods

Mixed-methods study using an online survey and semi-structured interviews. Participants were FPs from the canton of Vaud who had included ≥1 patient in the screening program. We used multivariate logistic regression to compare FPs offering only colonoscopy to those who offered a choice of tests or FIT.

Results

The participation rate was 40% (177 respondents / 443 eligible). Most FPs (68%) reported informing more than 75% of eligible patients about the program. Lack of time (n = 86, 33%) was the principal reason cited for not informing patients. Regarding the screening methods, 20% (n = 36) of FPs prescribed only colonoscopy, 13% (n = 23) only FIT and 65% (n = 115) both screening methods. Predictors of offering only colonoscopy rather than a choice of screening tests included: first, FP reporting that they chose/would choose colonoscopy for themselves (OR 8.54 [95% CI 1.83–39.79, P < 0.01]); second, being > 20 years in practice (OR 4.8 [95% CI 1.3–0.17.66, P = 0.02]); and third, seeing 300 or more patients per month (OR 3.05 [95% CI 1.23–7.57, P = 0.02]). When asked what could improve the program, 17% (n = 31) wrote that patients should be informed in advance about the program by postal mail and a large-scale communication campaign.

Conclusion

The majority of FPs reported CRC screening practices consistent with the objectives of the program. However, to ensure that patients are well informed and to save time, all patients need to be systematically informed about the program. Further, FPs should be encouraged to offer a choice of tests.

Associations with the Receipt of Colon Cancer Screening Among a Diverse Sample of Arab Americans in NYC

Arab Americans (AA) face increased risk for colorectal cancer (CRC), the third leading cause of cancer-related death in the US, due to low utilization of preventative care and socioeconomic disparities. This study explores associations with the receipt of CRC screening among AA in New York City. A cross-sectional survey was conducted among 100 individuals attending religious and community organizations with interviewer-administered surveys in Arabic and English. Results from 100 participants showed they were more likely to complete CRC screening with a doctor recommendation (74%) and were more likely to get a recommendation with a high school education or higher (86%). Uninsured participants and those with public insurance were the least likely to complete screening. Those with a higher mean score in Spiritual Life/Faith (13.34 vs. 11.67) were less likely to complete screening. Findings suggest the need for culturally sensitive interventions to increase CRC screening rates among AA.

Level and Factors Associated with Participation in Population-Based Cancer Screening in Safranbolu District of Karabuk, Turkey

BACKGROUND

Cervix, breast and colorectal cancers are included in the national population-based screening (PBS) program in Turkey. This study aimed to assess participation in PBSs for these cancers and to identify factors associated with participation in screenings in Safranbolu district of Karabuk, Turkey in 2016-2017.

METHODS

In this cross-sectional study, separate studying groups for cervix, breast and colorectal cancers were identified, taking into account the target age range specified in the national screening standards. The sample size was determined to be 374 for cervical cancer, 371 for breast cancer and 373 for colorectal cancer in the Epi-Info StatCalc program with a prevalence of 50%, a 95% Confidence Interval (CI) and a 5% error margin. The results of the data collected through face-to-face interview using questionnaires were evaluated with Chi-square tests (P<0.05) and included in the binary logistic regression model.

RESULTS

Participation in PBS at least once between 2011 and 2016 years was 26.2% for cervical cancer, 27.6% for breast cancer and 31.6% for colorectal cancer, whereas the level of PBS or opportunistic screening at least once was 51.1%, 42.7% and 32.2%, respectively. A 2.9-fold increase in participation for the cervical cancer screening was associated with informing women about cervical cancer by the family physicians. Being married and living in the district center showed associations with a higher rate of participation for colorectal cancer screening.

CONCLUSION

Participation in PBS was low for the 5.5-year period. More effort is needed to increase the effectiveness of the program.

Assessing knowledge on preventive colorectal cancer screening in Saudi Arabia: A cross-sectional study

Context

According to the Saudi Cancer Registry's 2014 Cancer Incidence Report, colorectal cancer (CRC) is the leading form of malignant cancer among Saudi men and ranks third among women. Raising awareness about CRC risk factors could lead to a significant decline in incidence of disease.

Aims

To assess CRC awareness and evaluate the main barriers that might prevent individuals' participation in screening.

Settings and Design

A self-administered survey was conducted over two days as part of a CRC awareness campaign in Jeddah, Saudi Arabia in March, 2018.

Methods and Materials

The survey addressed issues regarding knowledge of CRC and available screening methods. The survey also examined barriers that might make one reluctant to undergo preventative screening. Stata/SE 15.0 was used for all statistical analyses.

Statistical Analyses

Continuous variables were described with frequencies and percentages. Stepwise linear regression models were constructed to predict CRC knowledge and barriers.

Results

Out of 422 participants, 50.2% were men. Most respondents were between 15-35 years old (65.8%). Multivariate analysis revealed that gender was a significant predictor of CRC knowledge. Furthermore, the variables of education and family history of CRC significantly predicted subjects' awareness of colonoscopic screenings. The most common barriers for seeking screening included fear of the procedure, absence of clinical symptoms, and fear of the results.

Conclusions

Our results highlight deficits in public CRC knowledge and their awareness of preventative measures. These shortcomings were found to be mainly related to education level. Specific barriers affecting screening decisions were also identified; intensive efforts on awareness to overcome these obstacles will be required.

Disparities in health care determine prognosis in newly diagnosed glioblastoma

OBJECTIVE Glioblastoma (GBM) is an aggressive brain malignancy with a short overall patient survival, yet there remains significant heterogeneity in outcomes. Although access to health care has previously been linked to impact on prognosis in several malignancies, this question remains incompletely answered in GBM. METHODS This study was a retrospective analysis of 354 newly diagnosed patients with GBM who underwent first resection at the authors' institution (2007-2015). RESULTS Of the 354 patients (median age 61 years, and 37.6% were females), 32 (9.0%) had no insurance, whereas 322 (91.0%) had insurance, of whom 131 (40.7%) had Medicare, 45 (14%) had Medicaid, and 146 (45.3%) had private insurance. On average, insured patients survived almost 2-fold longer (p < 0.0001) than those who were uninsured, whereas differences between specific insurance types did not influence survival. The adjusted hazard ratio (HR) for death was higher in uninsured patients (HR 2.27 [95% CI 1.49-3.33], p = 0.0003). Age, mean household income, tumor size at diagnosis, and extent of resection did not differ between insured and uninsured patients, but there was a disparity in primary care physician (PCP) status-none of the uninsured patients had PCPs, whereas 72% of insured patients had PCPs. Postoperative adjuvant treatment rates with temozolomide (TMZ) and radiation therapy (XRT) were significantly less in uninsured (TMZ in 56.3%, XRT in 56.3%) than in insured (TMZ in 75.2%, XRT in 79.2%; p = 0.02 and p = 0.003) patients. Insured patients receiving both agents had better prognosis than uninsured patients receiving the same treatment (9.1 vs 16.34 months; p = 0.025), suggesting that the survival effect in insured patients could only partly be explained by higher treatment rates. Moreover, having a PCP increased survival among the insured cohort (10.7 vs 16.1 months, HR 1.65 [95% CI 1.27-2.15]; p = 0.0001), which could be explained by significant differences in tumor diameter at initial diagnosis between patients with and without PCPs (4.3 vs 4.8 cm, p = 0.003), and a higher rate of clinical trial enrollment, suggesting a critical role of PCPs for a timelier diagnosis of GBM and proactive cancer care management. CONCLUSIONS Access to health care is a strong determinant of prognosis in newly diagnosed patients with GBM. Any type of insurance coverage and having a PCP improved prognosis in this patient cohort. Higher rates of treatment with TMZ plus XRT, clinical trial enrollment, fewer comorbidities, and early diagnosis may explain survival disparities. Lack of health insurance or a PCP are major challenges within the health care system, which, if improved upon, could favorably impact the prognosis of patients with GBM.

Effect of financial incentives on breast, cervical and colorectal cancer screening delivery rates: Results from a systematic literature review

Preventive care, such as screening, is important for reducing the risk of cancer, a leading cause of death worldwide. Indeed, some type of cancers are detected through screening programs, which in most countries run for colorectal, breast, and cervical cancers. In this context, general practitioners play a key role in increasing the participation rate in cancer screening programs. To improve cancer screening delivery rates, performance incentives have increasingly been implemented in primary care by healthcare payers and organizations in different countries. The effects of these tools are still not clear. We conducted a systematic literature review in order to answer the following research question: What is the evidence in the literature for the effects of financial incentives on the delivery rates of breast, cervical and colorectal cancer screening in general practice? We performed a literature search in Web of Science, PubMed, Cochrane Library and Google Scholar, according to the PRISMA guidelines. 18 studies were selected, classified and discussed according to the health preventive services investigated. Most of studies showed partial or no effects of financial incentives on breast and cervical cancer screening delivery rates. Few positive or partial effects were found regarding colorectal cancer screening. Ongoing monitoring of incentive programs is critical to determining the effectiveness of financial incentives and their effects on the improvement of cancer screening delivery rates.

Integrated people-centred primary health care in Greece: unravelling Ariadne's thread

The 40th anniversary of the World Health Organization Alma-Ata Declaration in Astana offered the impetus to discuss the extent to which integrated primary health care (PHC) has been successfully implemented and its impact on research and practice. This paper focuses on the experiences from Greece in implementing primary health care reform and lessons learned from the conduct of evidence-based research. It critically examines what appears to be impeding the effective implementation of integrated PHC in a country affected by the financial and refugee crisis. The key challenges for establishing integrated people-centred primary care include availability of family physicians, information and communication technology, the prevention and management of chronic disease and migrant and refugees' health. Policy recommendations are formulated to guide the primary health care reform in Greece, while attempting to inform efforts in other countries with similar conditions.

Viewpoints of the target population regarding barriers and facilitators of colorectal cancer screening in the Czech Republic

BACKGROUND

Public awareness of colorectal cancer (CRC) and uptake of CRC screening remain challenges. The viewpoints of the target population (asymptomatic individuals older than 50) regarding CRC screening information sources and the reasons for and against participation in CRC screening are not well known in the Czech Republic. This study aimed to acquire independent opinions from the target population independently on the health system.

AIM

To investigate the viewpoints of the target population regarding the source of information for and barriers and facilitators of CRC screening.

METHODS

A survey among relatives (aged 50 and older) of university students was conducted. Participants answered a questionnaire about sources of awareness regarding CRC screening, reasons for and against participation, and suggestions for improvements in CRC screening. The effect of certain variables on participation in CRC screening was analyzed.

RESULTS

Of 498 participants, 478 (96%) respondents had some information about CRC screening and 375 (75.3%) had participated in a CRC screening test. General practitioners (GPs) (n = 319, 64.1%) and traditional media (n = 166, 33.3%) were the most common information sources regarding CRC screening. A lack of interest or time and a fear of colonoscopy or positive results were reported as reasons for non-participation. Individuals aged > 60 years [adjusted odds ratio (aOR) = 2.30, 95% confidence interval (CI) (1.42-3.71), P = 0.001], females (aOR = 1.95, 95%CI (1.26-3.01) P = 0.003), and relatives of CRC patients (aOR = 4.17, 95%CI (1.82-9.58) P = 0.001) were more likely to participate in screening. Information regarding screening provided by physicians - GPs: (aOR = 8.11, 95%CI (4.90-13.41), P < 0.001) and other specialists (aOR = 4.19, 95%CI (1.87-9.38), P = 0.001) increased participation in screening. Respondents suggested that providing better explanations regarding screening procedures and equipment for stool capturing could improve CRC screening uptake.

CONCLUSION

GPs and other specialists play crucial roles in the successful uptake of CRC screening. Reduction of the fear of colonoscopy and simple equipment for stool sampling might assist in improving the uptake of CRC screening.

A motivational phone call improves participation to screening colonoscopy for those with a positive FIT in a national screening programme (NCT 03276091)

BACKGROUND

A large proportion of individuals with a positive faecal immunologic test (FIT) will never undergo the recommended colonoscopy despite a full sequence of reminders.

AIMS

This prospective study aimed to recruit refractory individuals by a motivational personalised phone call given by a screening physician.

METHODS

We evaluated the impact of a motivational phone call given by a physician of the screening organisation in order to convince patients with positive FIT to undergo a colonoscopy.

RESULTS

115 individuals with a positive FIT were targeted. After GP phone call, it was ascertained that 15 had had a colonoscopy, one died, one moved outside the region, and the GP refused the study phone call for 13. Finally, we attempted to call 85 individuals; 24 could not be reached, 5 colonoscopies had been performed, and thus 56 individuals were included. The main reason for colonoscopy refusal (33.9%) was wrong advice from the GP or the gastroenterologist. Among those included, 33.9% (19/56) underwent the colonoscopy within 22.7 months after FIT; 1 invasive cancer, 18 adenomas and 9 serrated sessile lesions were found.

CONCLUSION

Motivational phone call performed by a physician from the screening organisation is effective to recruit a third of refractory individuals. Education for GPs and gastroenterologists is necessary to increase participation to colonoscopy and to avoid the performance of an inappropriate secondary FIT.

Impact of comorbid conditions on participation in an organised colorectal cancer screening programme: a cross-sectional study

Background

There is controversy regarding how comorbidity impacts on colorectal cancer screening, especially in the context of organised programmes. The aim of this study is to assess the effect of comorbidities on participation in the Barcelona population-based colorectal cancer screening programme (BCCSP).

Methods

Cross-sectional study carried out in ten primary care centres involved in the BCCSP. Individuals aged 50 to 69, at average risk of colorectal cancer, who were invited to participate in the first round of the faecal immunochemical test-based BCCSP were included (2011–2012). The main variable was participation in the BCCSP. Comorbidity was assessed by clinical risk group status. Other adjusting variables were age, sex, socioeconomic deprivation, visits to primary care, smoking, alcohol consumption and body mass index. Logistic regression models were used to test the association between participation in the programme and potential explanatory variables. The results were given as incidence rate ratios (IRR) and their 95% confidence intervals (CI).

Results

Of the 36,208 individuals included, 17,404 (48%) participated in the BCCSP. Participation was statistically significantly higher in women, individuals aged 60 to 64, patients with intermediate socioeconomic deprivation, and patients with more medical visits. There was a higher rate of current smoking, high-risk alcohol intake, obesity and individuals in the highest comorbidity categories in the non-participation group. In the adjusted analysis, only individuals with multiple minor chronic diseases were more likely to participate in the BCCSP (IRR 1.14; 95% CI [1.06 to 1.22]; p < 0.001). In contrast, having three or more dominant chronic diseases was associated with lower participation in the screening programme (IRR 0.76; 95% CI [0.65 to 0.89]; p = 0.001).

Conclusions

Having three or more dominant chronic diseases, was associated with lower participation in a faecal immunochemical test-based colorectal cancer screening programme, whereas individuals with multiple minor chronic diseases were more likely to participate. Further research is needed to explore comorbidity as a cause of non-participation in colorectal cancer screening programmes and which individuals could benefit most from colorectal cancer screening.

Approaching the Hard-to-Reach in Organized Colorectal Cancer Screening: an Overview of Individual, Provider and System Level Coping Strategies

BACKGROUND

Despite the proven effectiveness of colorectal cancer (CRC) screening on reduction of CRC mortality, the uptake of CRC screening remains low. Participation rate is one of determinants for the success of organized population-based screening program. This review aims to identify those who are hard-to-reach, and summarize the strategies to increase their screening rate from individual, provider and system levels.

METHODS

A systematic search of electronic English databases was conducted on the factors and strategies of uptake in CRC screening for the hard-to-reach population up to May 2017.

DISCUSSION

The coverage rate and participation rate are two indexes to identify the hard-to-reach population in organized CRC screening program. However, the homeless, new immigrants, people with severe mental illness, the jail intimates, and people with characteristics including lower education levels and/or low socioeconomic status, living in rural/remote areas, without insurance, and racial minorities are usually recognized as hard-to-reach populations. For them, organized screening programs offer a better coverage, while novel invitation approaches for eligible individuals and multiple strategies from primary care physicians are still needed to enhance screening rates among subjects who are hard-to-reach. Suggestions implied the effectiveness of interventions at the system level, including linkages to general practice; use of decision making tools; enlisting supports from coalition; and the continuum from screening to diagnosis and treatment.

CONCLUSION

Organized CRC screening offers a system access to approach the hard-to-reach populations. To increase their uptake, multiple and novel strategies from individual, provider and system levels should be applied. For policymakers, public healthcare providers and community stakeholders, it is a test to tailor their potential needs and increase their participation rates through continuous efforts to eliminate disparities and inequity in CRC screening service.

Disparities in Cancer Screening Practices among Minority and Underrepresented Populations

OBJECTIVES

To review current evidence about cancer screening challenges that lead to cancer health disparities in minority populations.

DATA SOURCES

Research reports, published journal articles, web sites, and clinical practice observations.

CONCLUSION

There are significant disparities that exist in cancer screening practices among racial and ethnic minority and underrepresented populations, resulting in disproportionately higher cancer mortality rates in these populations.

IMPLICATIONS FOR NURSING PRACTICE

Nurses are positioned to lead in educating, promoting, and bringing awareness to cancer screening recommendationsand current cancer prevention guidelines for at-risk individuals, and help them to implement these guidelines to reduce incidence and mortality.

Trends in breast and colorectal cancer screening among U.S. adults by race, healthcare coverage, and SES before, during, and after the great recession

The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.
