Colonoscopy utilization in the Black Women's Health Study

Acceptability of a Salon-Based Intervention to Promote Colonoscopy Screening Among African American Women

African American women have the highest colorectal cancer incidence and mortality rates among women of any race/ethnicity in the United States. Colonoscopy screening is an efficacious procedure for the prevention and early detection of colorectal cancer, making it a promising tool in the effort to eliminate colorectal cancer disparities. Toward that end, the present qualitative study sought to assess acceptability of and preferences for a beauty salon-based intervention to promote colonoscopy screening among African American women. A total of 11 focus groups were conducted: 6 with staff from African American-serving salons ( n = 3 with salon owners, n = 3 with salon stylists) and 5 with African American salon clients. Theory-guided focus group questions were used to explore participants' beliefs, interests, and preferences associated with the proposed intervention. Results indicated that, across all subgroups, participants were highly supportive of the idea of a salon-based intervention to promote colonoscopy screening among African American women, citing reasons such as the commonplace nature of health discussions in salons and the belief that, with proper training, stylists could effectively deliver colorectal cancer-related health information to their clients. The greatest differences between salon staff and clients were found with respect to the specifics of the intervention. Staff focused more heavily on content-related issues, such as the specific information that should be stressed in the intervention, whereas clients focused largely on process-related issues, such as the preferred intervention formats and how stylists should present themselves to clients. The findings from this study offer both encouragement and important groundwork for the development of a salon-based, stylist-delivered intervention to promote colonoscopy screening among African American women.

Ethnic differences and predictors of colonoscopy, prostate-specific antigen, and mammography screening participation in the multiethnic cohort

PURPOSE

Given the relation between screening and improved cancer outcomes and the persistence of ethnic disparities in cancer mortality, we explored ethnic differences in colonoscopy, prostate-specific antigen (PSA), and mammography screening in the Multiethnic Cohort Study.

METHODS

Logistic regression was applied to examine the influence of ethnicity as well as demographics, lifestyle factors, comorbidities, family history of cancer, and previous screening history on self-reported screening participation collected in 1999-2002.

RESULTS

The analysis included 140,398 participants who identified as white, African American, Native Hawaiian, Japanese American, US born-Latino, or Mexican born-Latino. The screening prevalences overall were mammography: 88% of women, PSA: 45% of men, and colonoscopy: 35% of men and women. All minority groups reported 10-40% lower screening utilization than whites, but Mexican-born Latinos and Native Hawaiian were lowest. Men were nearly twice as likely to have a colonoscopy (OR=1.94, 95% CI=1.89-1.99) as women. A personal screening history, presence of comorbidities, and family history of cancer predicted higher screening utilization across modalities, but to different degrees across ethnic groups.

CONCLUSIONS

This study confirms previously reported sex differences in colorectal cancer screening and ethnic disparities in screening participation. The findings suggest it may be useful to include personal screening history and family history of cancer into counseling patients about screening participation.

Disparities in endoscopy use for colorectal cancer screening in the United States

It is well established that disparities exist for colorectal cancer (CRC) incidence rates and death. With screening, death from CRC may be considered a preventable occurrence. Endoscopy (flexible sigmoidoscopy and colonoscopy) is the only modality with therapeutic benefit of removal of pre-cancerous polyps. The Patient Protection and Affordable Care Act mandated that preventive screening services be covered, which includes endoscopy for colon cancer screening. Recent federal rules have eliminated cost sharing for polyp removal during screening colonoscopy in privately insured patients; however, this has not been mandated for Medicare patients. Understanding the current state of disparities in endoscopy use is important, as these policy changes will affect millions of patients. The purpose of this literature review was to summarize the known research on disparities in endoscopy use for colon cancer screening in the United States and highlight areas for future research.

Shared decision-making about colorectal cancer screening: a conceptual framework to guide research

OBJECTIVE

To develop a conceptual framework to guide research on shared decision-making about colorectal cancer (CRC) screening among persons at average risk and their providers.

METHODS

Based upon a comprehensive review of empirical literature and relevant theories, a conceptual framework was developed that incorporated patient characteristics, cultural beliefs, provider/health care system variables, health belief/knowledge/stage of adoption variables, and shared decision-making between patients and providers that may predict behavior. Relationships among concepts in the framework, shared decision-making process and outcomes, and CRC screening behavior were proposed. Directions for future research were presented.

RESULTS

Many of the concepts in the proposed framework have been examined in prior research. However, these elements have not been combined previously to explain shared decision-making about CRC screening.

CONCLUSION

Research is needed to test the proposed relationships and hypotheses and to refine the framework.

PRACTICE IMPLICATIONS

Findings from future research guided by the proposed framework may inform clinical practice to facilitate shared decision-making about CRC screening.

Scheduled out-patient endoscopy and lack of compliance in a minority serving tertiary institution

INTRODUCTION

Lack of adherence to appointments wastes resources and portends a poorer outcome for patients. The authors sought to determine whether the type of scheduled endoscopic procedures affect compliance.

METHODS

The authors reviewed the final endoscopy schedule from January 2010 to August 2010 in an inner city teaching hospital that serves a predominantly African American population. The final schedule only includes patients who did not cancel, reschedule or notify the facility of their inability to adhere to their care plan up to 24 hours before their procedures. All patients had face to face consultation with gastroenterologists or surgeons before scheduling. The authors identified patients who did not show up for their procedures. They used Poisson regression models to calculate relative risks (RR) and 95% confidence intervals (CI).

RESULTS

Of 2183 patients who were scheduled for outpatient endoscopy, 400 (18.3%) patients were scheduled for Esophago-gastro-duodenoscopy (EGD), 1,335 (61.2%) for colonoscopy and 448 (20.5%) for both EGD and colonoscopy. The rate of noncompliance was 17.5%, 22.8% and 22.1%, respectively. When compared with those scheduled for only EGD, patients scheduled for colonoscopy alone (RR = 1.47; 95% CI: 1.13-1.92) and patients scheduled for both EGD and colonoscopy (RR = 1.36; 95% CI: 1.01-1.84) were less likely to show up for their procedures.

CONCLUSIONS

This study suggests a high rate of noncompliance with scheduled out-patient endoscopy, particularly for colonoscopy. Because this may be a contributing factor to colorectal cancer disparities, increased community outreach on colorectal cancer education is needed and may help to reduce noncompliance.

Examining the association between socioeconomic status and invasive colorectal cancer incidence and mortality in California

BACKGROUND

Colorectal cancer (CRC) incidence and mortality rates vary across race/ethnicity. Socioeconomic status (SES) also influences CRC rates; however, these associations might be inconsistent across racial/ethnic groups and tumor subsite. We examined associations between area-level SES and CRC incidence and mortality in a population-based registry study of non-Hispanic Whites, African Americans, Hispanics, and Asians/Pacific Islanders from California.

METHODS

Data on 52,608 incident CRC cases (1998-2002) and 14,515 CRC deaths (1999-2001) aged ≥50 years were obtained from the California Cancer Registry. Based on 2000 U.S. Census data, each cancer case and death was assigned a multidimensional census tract-level SES index. SES-specific quintiles of CRC incidence and mortality rates, incidence rate ratios (IRR) and mortality rate ratios, and 95% confidence intervals (CI) were estimated. Analyses were stratified by anatomical site, including left- versus right-sided tumors, race/ethnicity, and stage of disease.

RESULTS

Overall CRC incidence and SES did not show a clear association, yet patterns of associations varied across tumor subsite and race/ethnicity. Positive associations between SES and CRC incidence were found in Hispanics [SES Q5 v. Q1: IRR = 1.54, CI = 1.39-1.69], irrespective of the subsite. For Whites [SES Q5 v. Q1: IRR = 0.80, CI = 0.77-0.83], and African Americans [SES Q5 v. Q1: IRR = 0.83, CI = 0.70-0.97] inverse associations were observed, predominantly for left-sided tumors. Mortality rates declined with increasing SES in Whites, whereas in Hispanics mortality rates significantly increased with SES.

CONCLUSIONS

Our findings show that SES differences in CRC incidence and mortality vary considerably across anatomical subsite and race/ethnicity.

IMPACT

Studies combining area- and individual-level SES information are warranted.

Socioeconomic and physician supply determinants of racial disparities in colorectal cancer screening

PURPOSE

Causes of racial disparities in colorectal cancer (CRC) screening may extend beyond individual-level characteristics. We examined how physician density, beyond socioeconomic factors, affected observed racial disadvantages in recent CRC screening for blacks and Hispanics.

METHODS

We obtained socioeconomic and CRC screening information on adults age ≥ 50 years from the Behavioral Risk Factor Surveillance System (1997 to 2008) and information on the number of primary care physicians and gastroenterologists from the American Medical Association Masterfile (1997 to 2008). We used fixed-effect multivariate logistic regression to model the probability of receiving a fecal occult blood test within the past year or endoscopic screening within the past 5 years as a function of individual-level socioeconomic factors and state-level physician supply.

RESULTS

In 2008, 60.6% of whites were current on CRC screening (95% CI, 60.6% to 61.0%) compared with 57.9% of blacks (95% CI, 56.7% to 59.2%) and 42.9% of Hispanics (95% CI, 41.0% to 44.8%). Inclusion of socioeconomic variables reversed black-white disparities (odds ratio [OR], 1.17; 95% CI, 1.15 to 1.19) but did not explain disadvantage for Hispanics (OR, 0.89; 95% CI, 0.87 to 0.92). Once interaction of race and physician supply was considered, likelihood of recent CRC screening became statistically indistinguishable for Hispanics and whites of similar socioeconomic status residing in states with high physician supplies.

CONCLUSION

Socioeconomic factors and physician supply are key predictors of CRC screening. Adjustment for socioeconomic determinants explained black-white disparities; further adjustment for physician supply explained Hispanic-white disparities. Physician distribution is a potentially remediable contributor to ethnic/racial disparities in CRC screening. Whether the United States is able to equitably meet future demand for screening may depend on access, physician supply, and organization of the health care system.

Training community health workers about cancer clinical trials

Innovative projects to reduce disparities in cancer treatment and research include partnerships between academic and community cancer centers, patient navigation programs and strategies to promote community awareness, education and engagement. A 4 h training program about cancer clinical trials was developed through a needs assessment and in collaboration with community health workers who served as consultants and a larger advisory board comprised of community health workers, educators and clinical trialists. This program was delivered first as a collaboration between a phsycian who is experienced in the conduct of clinical research and two community health workers, and subsequently by the community health workers alone. We report on four workshops attended by a total of 61 community health workers recruited from Boston-area hospitals, community health centers and outreach programs. Support for and knowledge of clinical trials was measured in a pretest and post-test, which also included a satisfaction rating. Participants had a range of prior experience with clinical trials in the context of their personal and professional experience. Mean accuracy of knowledge about clinical trials increased from 72 to 84%, support for clinical trials improved considerably, and satisfaction with the training experience was high. Knowledge gaps and low levels of support for cancer clinical trials among community health workers can be improved with a short training program delivered by other community health workers. Further research is needed to identify the impact of this training on accrual to cancer clinical trials.

Obesity and Cancer Screening according to Race and Gender

The relationship between obesity and cancer screening varies by screening test, race, and gender. Most studies on cervical cancer screening found a negative association between increasing weight and screening, and this negative association was most consistent in white women. Recent literature on mammography reports no association with weight. However, some studies show a negative association in white, but not black, women. In contrast, obese/overweight men reported higher rates of prostate-specific antigen (PSA) testing. Comparison of prostate cancer screening, mammography, and Pap smears implies a gender difference in the relationship between screening behavior and weight. In colorectal cancer (CRC) screening, the relationship between weight and screening in men is inconsistent, while there is a trend towards lower CRC screening in higher weight women.
