Factors related to longitudinal adherence in colorectal cancer screening:qualitative research findings

Background: The effectiveness of screening in colorectal cancer prevention depends on sustained participation rates. The objective of this study was to explore factors related to the longitudinal adherence of screening behavior in the context of a biennial population-based cancer screening program. Methods: Eight focus groups were conducted with individuals who were invited two or three consecutive times to a population-based colorectal cancer screening program using a fecal occult blood test and who agreed to participate in the program at least once (n = 45). The criteria used to select the study members included adherence to fecal occult blood test maintenance, factors regarding their initial participation in the colorectal cancer screening, sex, and contextual educational level. Results: The participants expressed a high level of satisfaction with the program; however, they showed a low level of understanding with respect to cancer screening. Consulting a general practitioner was cited by all participants as an important factor that mediated their final decision or influenced their behavior as a whole with regard to the program. Fear played a different role in the screening behavior for regular and irregular adherent participants. In the adherent participants, fear facilitated their continued participation in the screening program, whereas for the irregular participants, fear led them to avoid or refuse further screening. Having a close person diagnosed with colorectal cancer was a facilitator for the regular adherent participants. The irregular adherent participants showed some relaxation with respect to screening after a negative result and considered that further screening was no longer necessary. Conclusion: Considering the importance of primary healthcare professionals in the decision regarding sustained participation, it is important to better engage them with cancer screening programs, as well as improve the communication channels to provide accurate and balanced information for both health professionals and individuals.</p

Interpersonal influences on patients’ surgical decision making: the role of close others

Patients make medical decisions in consultation with their partner, family, and friends. However, little is known about the ways in which these close others influence their decisions, particularly with respect to discrete decisions such as those related to medical treatments. This cross-sectional study investigated their influence on the surgical decisions of inflammatory bowel disease patients referred for surgery to remove their colon (N = 91). Guided by research on social control and classic research on power and influence in close relationships, we identified four types of close other decision influence: persuasion, assistance with understanding, indirect influence, and negative influence. Linear logistic and regression analyses showed that patients were more likely to have surgery when their close other used persuasion, and they reported lower decisional conflict when their close other helped them understand the decision. Patients were less likely to have surgery and reported greater decisional conflict when their close other used negative influence tactics. Findings demonstrate the importance of considering social context when investigating patient decision making

Organizational characteristics conducive to the implementation of health programs among Latino churches

Background Faith-based organizations (FBOs) can be effective partners in the implementation of health interventions to reach underserved audiences. However, little is known about the capacity they have or need to engage in these efforts. We examined inner-setting organizational characteristics hypothesized to be important for program implementation by the Consolidated Framework for Implementation Research (CFIR). Methods This cross-sectional study involved 34 churches with predominantly Latino congregations in Massachusetts. FBO leaders completed a survey assessing inner-setting CFIR organizational characteristics, including organizational readiness, implementation climate, organizational culture, and innovation “fit” with organizational mission. Results There was limited variability in CFIR organizational characteristics, with scores on a scale from 1 to 5 skewed toward higher values, ranging from 3.27 (SD 0.94) for implementation climate to 4.58 (SD 0.54). Twenty-one percent of the FBOs had offered health programs in the prior year. Conclusions FBOs had high scores on most of the organizational factors hypothesized to be important for the implementation of health programs, although relatively few FBOs offered them. While this suggests that FBOs have favorable characteristics for health programming, prospective studies are needed to understand relative salience of inner-setting organizational characteristics versus factors external to the organization (e.g., policies, incentives), as well as the potential direction of relationships between internal organizational characteristics and health program offerings.

Conducting Molecular Epidemiological Research in the Age of HIPAA: A Multi-Institutional Case-Control Study of Breast Cancer in African-American and European-American Women

Breast cancer in African-American (AA) women occurs at an earlier age than in European-American (EA) women and is more likely to have aggressive features associated with poorer prognosis, such as high-grade and negative estrogen receptor (ER) status. The mechanisms underlying these differences are unknown. To address this, we conducted a case-control study to evaluate risk factors for high-grade ER- disease in both AA and EA women. With the onset of the Health Insurance Portability and Accountability Act of 1996, creative measures were needed to adapt case ascertainment and contact procedures to this new environment of patient privacy. In this paper, we report on our approach to establishing a multicenter study of breast cancer in New York and New Jersey, provide preliminary distributions of demographic and pathologic characteristics among case and control participants by race, and contrast participation rates by approaches to case ascertainment, with discussion of strengths and weaknesses

A multilevel intervention to promote colorectal cancer screening among community health center patients: results of a pilot study

<p>Abstract</p> <p>Background</p> <p>Colorectal cancer screening rates are low among poor and disadvantaged patients. Patient navigation has been shown to increase breast and cervical cancer screening rates, but few studies have looked at the potential of patient navigation to increase colorectal cancer screening rates.</p> <p>Methods</p> <p>The objective was to determine the feasibility and effectiveness of a patient navigator-based intervention to increase colorectal cancer screening rates in community health centers. Patients at the intervention health center who had not been screened for colorectal cancer and were designated as "appropriate for outreach" by their primary care providers received a letter from their provider about the need to be screened and a brochure about colorectal cancer screening. Patient navigators then called patients to discuss screening and to assist patients in obtaining screening. Patients at a demographically similar control health center received usual care.</p> <p>Results</p> <p>Thirty-one percent of intervention patients were screened at six months, versus nine percent of control patients (p < .001).</p> <p>Conclusion</p> <p>A patient navigator-based intervention, in combination with a letter from the patient's primary care provider, was associated with an increased rate of colorectal cancer screening at one health center as compared to a demographically similar control health center. Our study adds to an emerging literature supporting the use of patient navigators to increase colorectal cancer screening in diverse populations served by urban health centers.</p

Variants in the vitamin D pathway, serum levels of vitamin D, and estrogen receptor negative breast cancer among African-American women: A case-control study

Introduction: American women of African ancestry (AA) are more likely than European Americans (EA) to have estrogen receptor (ER)-negative breast cancer. 25-hydroxyvitamin D (25OHD) is low in AAs, and was associated with ER-negative tumors in EAs. We hypothesized that racial differences in 25OHD levels, as well as in inherited genetic variations, may contribute, in part, to the differences in tumor characteristics.Methods: In a case (n = 928)-control (n = 843) study of breast cancer in AA and EA women, we measured serum 25OHD levels in controls and tested associations between risk and tag single nucleotide polymorphisms (SNPs) in VDR, CYP24A1 and CYP27B1, particularly by ER status.Results: More AAs had severe vitamin D deficiency ( twofold increased risk of ER-negative breast cancer among AAs (OR = 2.62, 95% CI = 1.38-4.98), but had no effect in EAs. rs2209314 decreased risk among EAs (OR = 0.38, 95% CI = 0.20-0.73), with no associations in AAs. The increased risk of ER-negative breast cancer in AAs compared to EAs was reduced and became non-significant (OR = 1.20, 95% CI = 0.80-1.79) after adjusting for these two CYP24A1 SNPs.Conclusions: These data suggest that genetic variants in the vitamin D pathway may be related to the higher prevalence of ER-negative breast cancer in AA women. © 2012 Yao et al.; licensee BioMed Central Ltd
