Colorectal cancer screening: prevalence among low-income groups with health insurance

The association of health insurance and race with treatment and survival in patients with metastatic colorectal cancer

Background

Black patients and underinsured patients with colorectal cancer (CRC) present with more advanced disease and experience worse outcomes. The study aim was to evaluate the interaction of health insurance status and race with treatment and survival in metastatic CRC.

Materials and methods

Patients diagnosed with metastatic CRC within NCDB from 2006–2016 were included. Primary outcomes included receipt of chemotherapy and 3-year all-cause mortality. Multivariable logistic regression and Cox-regression (MVR) including a two-way interaction term of race and insurance were performed to evaluate the differential association of race and insurance with receipt of chemotherapy and mortality, respectively.

Results

128,031 patients were identified; 70.6% White, 14.4% Black, 5.7% Hispanic, and 9.3% Other race. Chemotherapy use was higher among White compared to Black patients. 3-year mortality rate was higher for Blacks and lower for Hispanics, in comparison with White patients. By MVR, Black patients were less likely to receive chemotherapy. When stratified by insurance status, Black patients with private and Medicare insurance were less likely to receive chemotherapy than White patients. All-cause mortality was higher in Black patients and lower in Hispanic patients, and these differences persisted after controlling for insurance and receipt of chemotherapy.

Conclusion

Black patients and uninsured or under-insured patients with metastatic CRC are less likely to receive chemotherapy and have increased mortality. The effect of health insurance among Blacks and Whites differs, however, and improving insurance alone does not appear to fully mitigate racial disparities in treatment and outcomes.

Factors Influencing Recommended Cancer Screening in Low-Income African American Women in Tennessee

OBJECTIVE

This study examined the factors that predict recommended screening compliance to cervical, breast, and colorectal cancers in low-income African American women. It also examined obstacles to screenings by geographic region and screening status.

METHODS

As a part of the Meharry Community Networks Program (CNP) needs assessment, a 123-item community survey was administered to assess demographic characteristics, health care access and utilization, and screening practices for various cancers in low-income African Americans. For this study, only African American women 40 years and older (n = 308) were selected from the Meharry CNP community survey database.

RESULTS

There were several predictors to recommended screening such as being employed and having health insurance (P < 0.05). Additionally, the obstacles to screening posed a similar level of difficulty for participants from different geographic areas.

DISCUSSION

Sociodemographic differences and obstacles of screening need to be addressed in educational interventions aimed at improving cancer screenings.

Correlates of colorectal cancer screening rates in primary care clinics serving low income, medically underserved populations

INTRODUCTION

Screening for colorectal cancer (CRC) is effective in reducing CRC burden. Primary care clinics have an important role in increasing screening. We investigated associations between clinic-level CRC screening rates of the clinics serving low income, medically underserved population, and clinic-level screening interventions, clinic characteristics and community contexts.

METHODS

Using data (2015-16) from the Centers for Disease Control and Prevention's (CDC) Colorectal Cancer Control Program, we linked clinic-level data with county-level contextual data from external sources. Analysis variables included clinic-level CRC screening rates, four different evidence-based interventions (EBIs) intended to increase screening, clinic characteristics, and clinic contexts. In the analysis (2018), we used weighted ordinary least square multiple regression analyses to associate EBIs and other covariates with clinic-level screening rates.

RESULTS

Clinics (N = 581) had an average screening rate of 36.3% (weighted. Client reminders had the highest association (5.6 percentage points) with screening rates followed by reducing structural barriers (4.9 percentage points), provider assessment and feedback (3.2 percentage points), and provider reminders (<1 percentage point). Increases in the number of EBIs was associated with steady increases in the screening rate (5.4 percentage points greater for one EBI). Screening rates were 16.4 percentage points higher in clinics with 4 EBIs vs. no EBI. Clinic characteristics, contexts (e.g. physician density), and context-EBI interactions were also associated with clinic screening rates.

CONCLUSIONS

These results may help clinics, especially those serving low income, medically underserved populations, select individual or combinations of EBIs suitable to their contexts while considering costs.

Unraveling the Determinants to Colorectal Cancer Screening Among Asian Americans: a Systematic Literature Review

Colorectal cancer (CRC) is one of the top three cancers experienced among Asian American (AA) men and women. One effective way to decrease incidence and mortality from CRC is the adherence of regular CRC screening; however, AA continue to receive the lowest screening rates compared to other racial/ethnic groups. When disaggregating this heterogeneous population, further disparities exist between subgroups. Examination of facilitators and barriers to cancer screening among AA subgroups is fairly recent and the synthesis of this information is limited. As such, a systematic review was conducted examining the facilitators and the barriers among Chinese, Filipino, Korean, and Japanese Americans using a systematic literature review method. The Health Belief Model served as the primary theoretical framework for this study and used to organize and synthesize the facilitators and barriers to CRC screening. In total, 22 articles yielded 29 examinations of each of the AA subgroups. Different facilitators and barriers to screening uptake for each subgroup were revealed; however, consistent across all the subgroups was physician recommendation as a facilitator and participants' unawareness of screening tests and those stating having no problems/symptoms of CRC as a barrier across screening modalities. Tailored approach in outreach and intervention efforts are suggested when achieving to improve CRC screening in AA ethnic subgroups.

The Association Between Primary Source of Healthcare Coverage and Colorectal Cancer Screening Among US Veterans

BACKGROUND

Colorectal cancer (CRC) is a deadly but largely preventable disease. Screening improves outcomes, but screening rates vary across healthcare coverage models. In the Veterans Health Administration (VA), screening rates are high; however, it is unknown how CRC screening rates compare for Veterans with other types of healthcare coverage.

AIMS

To determine whether Veterans with Veteran-status-related coverage (VA, military, TRICARE) have higher rates of CRC screening than Veterans with alternate sources of healthcare coverage.

METHODS

We conducted a cross-sectional analysis of Veterans 50-75 years from the 2014 Behavioral Risk Factor Surveillance System survey. We examined CRC screening rates and screening modalities. We performed multivariable logistic regression to identify the role of coverage type, demographics, and clinical factors on screening status.

RESULTS

The cohort included 22,138 Veterans. Of these, 76.7% reported up-to-date screening. Colonoscopy was the most common screening modality (83.7%). Screening rates were highest among Veterans with Veteran-status-related coverage (82.3%), as was stool-based screening (10.8%). The adjusted odds of up-to-date screening among Veterans with Veteran-status-related coverage were 83% higher than among Veterans with private coverage (adjusted OR = 1.83, 95% CI = 1.52-2.22). Additional predictors of screening included older age, black race, high income, access to medical care, frequent medical visits, and employed or married status.

CONCLUSIONS

CRC screening rates were highest among Veterans with Veteran-status-related coverage. High CRC screening rates among US Veterans may be related to system-level characteristics of VA and military care. Insight to these system-level characteristics may inform mechanisms to improve CRC screening in non-VA settings.

Changes in colorectal cancer screening intention among people aged 18-49 in the United States

BACKGROUND

To determine whether exposure to a peer-led intervention focused on colorectal cancer (CRC) screening, physical activity, and multi-vitamin intake can lead to increased intentions to be screened for CRC once age eligible among adults under the age of 50.

METHODS

Participants were residents of low-income housing sites, and CRC screening intentions were assessed at baseline and at follow-up (approximately 2 years later) to determine changes in screening intentions and factors associated with changes in intentions.

RESULTS

Participants (n = 692) were 78.4% female, 42.6% Hispanic and 50.8% black. At follow-up, 51% maintained their intention to be screened and 14.6% newly intended to get screened. Individuals newly intending to get screened were more likely to have participated in the intervention, be older, male, and born in Puerto Rico or the United States compared to those who maintained their intention not to get screened (p < 0.05).

CONCLUSION

Exposure to CRC prevention messages before the age of 50 can increase screening intentions among individuals who did not initially intend to get screened. Peer-led interventions to promote CRC screening should include individual less than 50 years of age, as this may contribute to increased screening at the recommended age threshold.

Looking for the uninsured in Massachusetts? Check opioid dependent persons seeking detoxification

BACKGROUND

We examined the rate of uninsurance among persons seeking detoxification at a large drug treatment program in Massachusetts in 2013, five years after insurance mandates.

METHODS

We interviewed three hundred and forty opioid dependent persons admitted for inpatient detoxification in Fall River, Massachusetts. Potential predictors of self-reported insurance status included age, gender, ethnicity, employment, homelessness, years of education, current legal status, and self-perceived health status.

RESULTS

Participants mean age was 32 years, 71% were male, and 87% were non-Hispanic Caucasian. Twenty-three percent were uninsured. In the multivariate model, the odds of being uninsured was positively associated with years of education (OR=1.22, 95% CI=1.03; 1.46, p<.05), higher among males than females (OR=2.63, 95% CI=1.33; 5.20, p<.01), and inversely associated with age (OR=0.94, 95% CI=0.90; 0.98, p<.01).

CONCLUSION

Opioid dependent persons recruited from a detoxification program in Massachusetts are uninsured at rates far above the state average. With the arrival of the Affordable Care Act, drug treatment programs in Massachusetts and nationally will be important sites to target to expand health coverage.

Using Adult Children to Enhance Participation in Colorectal Cancer Screening

We pre-tested if a new communication strategy addressed to adult children could be effective in helping to improve colorectal cancer screening (CRCS) participation rates. In a first study we used a sample of undergraduate students who participated in an experiment with six different conditions to analyze their risk perceptions regarding CRCS and their family role. A second study with a portion of that sample was also achieved to give robustness to the findings. In addition, we achieved a third study using the first sample to replicate previous findings. In a fourth study we used a sample of participants above 50 years old in order to test if the responses regarding how adult children advise their parents and their perceived influence regarding adopting healthy behaviour were similar to parents’ responses to the same questions. A final fifth study was achieved to inquire about the reasons why adult children would decide to advise their parents if a hypothetical marketing campaign was targeted at them. The results showed that designing a communication campaign addressed to adult children could help to increase rates. This result is mainly derived from the role adult children play in a parent’s decision about health behaviour, and the willingness to influence parents to participate in the screening. Adult children could also prescribe CRCS to their parents, as health services or celebrities do. Therefore, they might help to convince the at-risk population to comply with the screening, and consequently, to enhance participation rates.

Clinical update: colon, rectal, and anal cancers

OBJECTIVES

To present an updated review of the incidence, risk factors, staging, diagnosis, and treatment of colon, rectal, and anal cancers, as well as nursing care associated with managing patients diagnosed with these malignancies.

DATA SOURCES

Published research reports, epidemiologic data, published patient management guidelines, and institution-based clinical tools.

CONCLUSION

While significant advances in the management of colon, rectal, and anal cancers in the past decade have extended patient survival, there remain some unanswered questions. Further clinical and molecular research will help individualize patient care, refining current therapeutic strategies and treatment decision-making aids while minimizing symptoms of disease and treatment.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to be familiar with risk factors, disease course, and current and emerging therapies to assist patients with treatment decision-making, and to anticipate and intervene in managing disease and treatment-induced problems. Early identification and management of distressing symptoms can help to avoid life-threatening effects and promote patient adherence to prescribed therapies; timely patient/family education may minimize anxiety and promote self-management.

Multilevel factors affecting quality: examples from the cancer care continuum

The complex environmental context must be considered as we move forward to improve cancer care and, ultimately, patient and population outcomes. The cancer care continuum represents several care types, each of which includes multiple technical and communication steps and interfaces among patients, providers, and organizations. We use two case scenarios to 1) illustrate the variability, diversity, and interaction of factors from multiple levels that affect care quality and 2) discuss research implications and provide hypothetical examples of multilevel interventions. Each scenario includes a targeted literature review to illustrate contextual influences upon care and sets the stage for theory-informed interventions. The screening case highlights access issues in older women, and the survivorship case illustrates the multiple transition challenges faced by patients, families, and organizations. Example interventions show the potential gains of implementing intervention strategies that work synergistically at multiple levels. While research examining multilevel intervention is a priority, it presents numerous study design, measurement, and analytic challenges.

Screening prevalence and incidence of colorectal cancer among American Indian/Alaskan natives in the Indian Health Service

BACKGROUND

Studies on colorectal cancer (CRC) screening and incidence among American Indian/Alaska Natives (AI/AN) are few.

AIMS

Our aim was to determine CRC screening prevalence and to calculate CRC incidence among AI/AN receiving care within the Indian Health Service (IHS).

METHODS

A retrospective cohort study of AI/AN who utilized IHS from 1996 to 2004. AI/AN who were average-risk for CRC and received primary care within IHS were identified by searching the IHS Resource Patient Management System for selected ICD-9/CPT codes (n = 142,051). CRC screening prevalence was calculated and predictors of screening were determined for this group. CRC incidence rates were ascertained for the entire AI/AN population ages 50-80 who received IHS medical care between 1996 and 2004 (n = 283,717).

RESULTS

CRC screening was performed in 4.0% of average-risk AI/AN. CRC screening was more common among women than men (RR = 1.6, 95% CI 1.4-1.7) and among AI/AN living in the Alaska region compared to the Pacific Coast region (RR = 2.5, 95% CI 2.2-2.8) while patients living in the Northern Plains (RR = 0.4, 95% CI 0.3-0.4) were less likely to have been screened. CRC screening was less common among patients with a greater number of primary care visits. The age-adjusted CRC incidence among AI/AN ages 50-80 was 227 cancers per 100,000 person-years.

CONCLUSIONS

CRC was common among AI/AN receiving medical care within IHS. However, CRC screening prevalence was far lower than has been reported for the U.S. population.

Massachusetts health reform and disparities in coverage, access and health status

BACKGROUND

Massachusetts health reform has achieved near-universal insurance coverage, yet little is known about the effects of this legislation on disparities.

OBJECTIVE

Since racial/ethnic minorities and low-income individuals are over-represented among the uninsured, we assessed the effects of health reform on disparities.

DESIGN

Cross-sectional survey data from the Behavioral Risk Factor Surveillance Survey (BRFSS), 2006-2008.

PARTICIPANTS

Adults from Massachusetts (n = 36,505) and other New England states (n = 63,263).

MAIN MEASURES

Self-reported health coverage, inability to obtain care due to cost, access to a personal doctor, and health status. To control for trends unrelated to reform, we compared adults in Massachusetts to those in all other New England states using multivariate logistic regression models to calculate adjusted predicted probabilities.

KEY RESULTS

Overall, the adjusted predicted probability of health coverage in Massachusetts rose from 94.7% in 2006 to 97.7% in 2008, whereas coverage in New England remained around 92% (p < 0.001 for difference-in-difference). While cost-related barriers were reduced in Massachusetts, there were no improvements in access to a personal doctor or health status. Although there were improvements in coverage and cost-related barriers for some disadvantaged groups relative to trends in New England, there was no narrowing of disparities in large part because of comparable or larger improvements among whites and the non-poor.

CONCLUSIONS

Achieving equity in health and health care may require additional focused intervention beyond health reform.

Impact of insurance type on survivor-focused and general preventive health care utilization in adult survivors of childhood cancer: the Childhood Cancer Survivor Study (CCSS)

BACKGROUND

Lack of health insurance is a key barrier to accessing care for chronic conditions and cancer screening. The influence of insurance type (private, public, none) on survivor-focused and general preventive health care in adult survivors of childhood cancer was examined.

METHODS

The Childhood Cancer Survivor Study is a retrospective cohort study of childhood cancer survivors diagnosed between 1970 and 1986. Among 8425 adult survivors, the relative risk (RR) and 95% confidence interval (CI) of receiving survivor-focused and general preventive health care were estimated for uninsured (n = 1390) and publicly insured (n = 640), compared with for the privately insured (n = 6395)

RESULTS

Uninsured survivors were less likely than those privately insured to report a cancer-related visit (adjusted RR, 0.83; 95% CI, 0.75-0.91) or a cancer center visit (adjusted RR, 0.83; 95% CI, 0.71-0.98). Uninsured survivors had lower levels of utilization in all measures of care in comparison with privately insured. In contrast, publicly insured survivors were more likely to report a cancer-related visit (adjusted RR, 1.22; 95% CI, 1.11-1.35) or a cancer center visit (adjusted RR, 1.41; 95% CI, 1.18-1.70) than were privately insured survivors. Although publicly insured survivors had similar utilization of general health examinations, they were less likely to report a Papanicolaou test or a dental examinations

CONCLUSIONS

Among this large, socioeconomically diverse cohort, publicly insured survivors utilize survivor-focused health care at rates at least as high as survivors with private insurance. Uninsured survivors have lower utilization of both survivor-focused and general preventive health care.

Colorectal cancer: national and international perspective on the burden of disease and public health impact

Colorectal cancer is a significant cause of morbidity and mortality in the United States and throughout the world. The importance of this disease to gastroenterologists cannot be understated, given that screening and surveillance colonoscopy are dominant segments of clinical practice. The United States is the only country in the world where incidence and mortality rates from colorectal cancer are reported to be decreasing significantly, but health disparities in cancer screening, treatment, and survival persist. Health disparities are also evident worldwide, where the impact of this disease is staggering. In fact, rates of cancer are increasing in many parts of the world. Eliminating barriers to cancer screening and treatment could lead to substantial gains in quality and quantity of life and decrease the burden of colorectal cancer on public health. Programmatic and opportunistic screening programs have already had a measurable impact on disease burden, although the optimal screening strategy remains a matter of debate. Screening programs vary throughout the world, and further refinement will require a tailored approach because of differences in politics and fiscal reality among individual countries. Despite the strong impact of colorectal cancer on public health, there is cause for optimism and room for hope.

Colorectal cancer prevention for low-income, sociodemographically-diverse adults in public housing: baseline findings of a randomized controlled trial

BACKGROUND

This paper presents the study design, intervention components, and baseline data from Open Doors to Health, a study designed to address social contextual factors in colorectal cancer (CRC) prevention for low-income, racial/ethnic minority populations.

METHODS

A cluster randomized design with 12 housing sites as the primary sampling units was used: 6 sites were assigned to a "Peer-led plus Screening Access" (PL) condition, and 6 were assigned to "Screening Access only" (SCR) condition. Study-related outcomes were CRC screening, physical activity (measured as mean steps/day), and multivitamin use.

RESULTS

At baseline (unweighted sample size = 1554), two-thirds self-reported that they were current with screening recommendations for CRC (corrected for medical records validation, prevalence was 52%), with half having received a colonoscopy (54%); 96% had health insurance. Mean steps per day was 5648 (se mean = 224), and on average 28% of the sample reported regular multivitamin use. Residents reported high levels of social support [mean = 4.40 (se = .03)] and moderately extensive social networks [mean = 2.66 (se = .02)].

CONCLUSION

Few studies have conducted community-based studies in public housing communities; these data suggest areas for improvement and future opportunities for intervention development and dissemination. Findings from the randomized trial will determine the effectiveness of the intervention on our health-related outcomes as well as inform future avenues of research.
