Patients whose physicians recommend colonoscopy and those who follow through

A Retrospective Analysis of Gender-Based Difference in Adherence to Initial Colon Cancer Screening Recommendations

Background: Colorectal cancer (CRC) is the fourth leading cause of cancer-related death in the United States, despite being largely preventable and treatable. Improving overall screening rates among both men and women is considered an important and effective strategy toward reducing morbidity and mortality from CRC. In order to optimize screening strategies, factors associated with decreased compliance need to be understood. This study aimed to compare initial CRC screening rates between males and females in a population of patients who presented for an annual physical examination. Methods: A retrospective chart review study of 380 patients designed to compare rates of initial CRC screening between males and females was conducted. Patients who were seen at our institution for an annual physical examination and were between 51 and 60 years of age were included. Results: There was no evidence of a difference in the rate of initial colon cancer screening between females (83.0%) and males (80.9%) in either unadjusted analysis (odds ratio = 1.16, P = .59) or in multivariable analysis adjusting for potential confounding variables (odds ratio = 1.16, P = .61). Conclusions: There was no significant difference in the rate of initial CRC screening between males and females who presented for an annual physical examination. This suggests that designing interventions to improve screening specific to gender may not be needed in a population of patients who attend routine preventive health examinations. Further study is needed in the general population to examine for gender-based differences in initial CRC screening among patients who do not regularly follow up for preventive examinations.

Predicting Incongruence between Self-reported and Documented Colorectal Cancer Screening in a Sample of African American Medicare Recipients

Assessments of colorectal cancer (CRC) screening rates typically rely on self-reported screening data, which are often incongruent with medical records. We used multilevel models to examine health-related, socio-demographic and psychological predictors of incongruent self-reports for CRC screening among Medicare-insured African Americans (N = 3,740). Results indicated that living alone decreased, and income increased, the odds of congruently self-reporting endoscopic CRC screening. Being male and having greater number of comorbidities decreased, and having less than a high school education increased, the odds of congruently self-reported fecal occult blood tests. Living alone, age and income had the most robust effects across classifications into one of four mutually exclusive categories defined by screening status (screened/unscreened) and congruence of self-reports. The results underscore the clinical importance of gathering socio-demographic data via patient interviews, and the relevance of these data for judging the veracity of self-reported CRC screenings behaviors.

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

Colorectal cancer (CRC) is the third most common type of cancer among both males and females in the United States and the second leading cause of cancer-related deaths. Although largely preventable through screening, early detection and removal of polyps, screening rates are considered sub-optimal. Perceived barriers to screening have been reported to influence screening rates. This paper examines variations in the extent to which uninsured patients identified barriers to CRC screening using colonoscopy based on race/ethnicity, educational attainment, age, gender, marital status and prior colonoscopy. Multivariate analyses showed that compared to Caucasians, African Americans had an increased likelihood of identifying lack of transportation as a barrier [odds ratio (OR) 2.68; 95 % confidence interval (CI) 1.35-5.32] while Hispanics were more likely to identify fear of finding cancer as a barrier (OR 2.09; 95 % CI 1.19-3.66). Compared to those with more than a high school education, there was increased likelihood of identifying lack of knowledge as a barrier among individuals with high school education (OR 3.51; 95 % CI 1.94-6.36) or less than a high school education (OR 2.16; 95 % CI 1.04-4.50). Our findings suggest that strategies aimed at increasing colonoscopy screening rates among underserved populations should take into consideration race/ethnicity, educational attainment, age, and prior colonoscopy experience when developing education and outreach plans to reduce barriers to colonoscopy.

Physician use of persuasion and colorectal cancer screening

The impact of patient-physician communication on subsequent patient behavior has rarely been evaluated in the context of colorectal cancer (CRC) screening discussions. We describe physicians' use of persuasive techniques when recommending CRC screening and evaluate its association with patients' subsequent adherence to screening. Audio recordings of N = 414 periodic health examinations were joined with screening use data from electronic medical records and pre-/post-visit patient surveys. The association between persuasion and screening was assessed using generalized estimating equations. According to observer ratings, primary care physicians frequently use persuasive techniques (63 %) when recommending CRC screening, most commonly argument or refutation. However, physician persuasion was not associated with subsequent screening adherence. Physician use of persuasion may be a common vehicle for information provision during CRC screening discussions; however, our results do not support the sole reliance on persuasive techniques if the goal is to improve adherence to recommended screening.

Predicting Colonoscopy Completion Among African American and Latino/a Participants in a Patient Navigation Program

Patient navigation (PN) effectively increases screening colonoscopy (SC) rates, a key to reducing deaths from colorectal cancer (CRC). Ethnic minority populations have disproportionately low SC rates and high CRC mortality rates and, therefore, especially stand to benefit from PN. Adapting the Health Belief Model as an explanatory model, the current analysis examined predictors of SC rates in two randomized studies that used PN to increase SC among 411 African American and 461 Latino/a patients at a large urban medical center. Speaking Spanish but not English (odds ratio (OR), 2.192; p < 0.005), having a higher income (OR, 1.218; p < 0.005), and scoring higher on the Pros of Colonoscopy scale (OR, 1.535; p = 0.023) independently predicted colonoscopy completion. Health education and PN programs that increase awareness of the benefits of getting a colonoscopy may encourage colonoscopy completion. In the context of language-appropriate PN programs for African American and Latino/a individuals, those with lower incomes and English speakers may require additional education and counseling to support their decision-making around colonoscopy.

Pathways to colonoscopy in the South: seeds of health disparities

OBJECTIVES

We aimed to highlight sociodemographic differences in how patients access colonoscopy.

METHODS

We invited all eligible patients (n = 2500) from 2 academy-affiliated colonoscopy centers in Alachua County, Florida (1 free standing, 1 hospital based), to participate in a precolonoscopy survey (September 2011-October 2013); patients agreeing to participate (n = 1841, response rate = 73.6%) received a $5.00 gift card.

RESULTS

We found sociodemographic differences in referral pathway, costs, and reasons associated with obtaining the procedure. Patients with the ideal pathway (referred by their regular doctor for age-appropriate screening) were more likely to be Black (compared with other minorities), male, high income, employed, and older. Having the colonoscopy because of symptoms was associated with being female, younger, and having lower income. We found significant differences for 1 previously underestimated barrier, having a spouse to accompany the patient to the procedure.

CONCLUSIONS

Patients' facilitators and barriers to colonoscopy differed by sociodemographics in our study, which implies that interventions based on a single facilitator will not be effective for all subgroups of a population.

Public health and cooperative group partnership: a colorectal cancer intervention

OBJECTIVES

To describe the development of a multi-component colorectal cancer educational tool for female breast cancer survivors through a cooperative group and public health partnership.

DATA SOURCES

PubMed, World Wide Web, guidelines from professional organizations, surveys and focus groups with breast cancer survivors.

CONCLUSION

Collaboration is at the core of cooperative group and public health research. This partnership led to the development of a colorectal cancer educational tool for breast cancer survivors. Focus groups revealed that female breast cancer survivors were receptive to education on colorectal cancer screening.

IMPLICATIONS FOR NURSING PRACTICE

Nurses are instrumental in research collaborations between cooperative groups and public health. The colorectal educational intervention for breast cancer survivors serves as an exemplar of partnerships leading to innovative research planning and implementation outcomes.
