Abstract
IMPORTANCE Although screenings for breast and colorectal cancer are widely recommended, patient screening rates vary greatly and remain below public health targets, and primary care physicians' (PCPs') counseling and referrals play critical roles in patients' use of cancer screenings. Recent adverse events may influence PCPs' decision-making, but it remains unknown whether cancer screening rates of PCPs' patients change after PCPs are exposed to new cancer diagnoses. OBJECTIVE To investigate whether PCPs' exposures to patients with new diagnoses of breast or colorectal cancer were associated with changes in screening rates for other patients subsequently visiting the affected PCPs. DESIGN, SETTING, AND PARTICIPANTS This cohort study used stacked difference-in-differences analyses of all-payer claims data for New Hampshire and Maine in 2009 to 2015. Participants were PCPs caring for patients. Data analysis was performed from June 2020 to May 2022. EXPOSURES New diagnosis of a PCP's patient with breast cancer or colorectal cancer. MAIN OUTCOMES AND MEASURES Patients' breast and colorectal cancer screening rates within 1 year of a PCP visit. RESULTS The sample included 3158 PCPs (1819 male PCPs [57.6%]) caring for 1 920 189 patients (1 073 408 female patients [55.9%]; mean [SD] age, 41.0 [21.9] years) aged 18 to 64 years. During the study period, 898 PCPs had a patient with a new diagnosis of breast cancer and 370 PCPs had a patient with a new diagnosis of colorectal cancer. In the preexposure period, 68 837 female patients (37.3% of those visiting a PCP) underwent breast cancer screening within 1 year of the visit, and 13 137 patients (10.1% of those visiting a PCP) underwent colorectal cancer screening within 1 year of the visit. For both cancer types, after exposure to a new cancer diagnosis, PCPs' cancer screening rates displayed a rapid, sustained increase. Breast cancer screening rates increased by 4.5 percentage points (95% CI, 3.0-6.1 percentage points; P < .001). Colorectal cancer screening rates increased by 1.3 percentage points (95% CI, 0.3-2.2 percentage points; P = .01). Observed breast cancer screening increases were higher for male PCPs than for female PCPs (3.1 percentage points; 95% CI, 0.4-5.8 percentage points; P = .03). CONCLUSIONS AND RELEVANCE This study found significant, sustained increases in cancer screening rates for patients visiting PCPs recently exposed to new breast and colorectal cancer diagnoses. These findings suggest that PCPs may update practice patterns on the basis of recent patient diagnoses. Future work should assess whether salient cues to PCPs about patient diagnoses when clinically appropriate can improve screening practices.

Abstract
BACKGROUND Cancer prevention is a crucial challenge in preventive medicine. Several studies have suggested that voluntary health check-ups and recommendations from health professionals are associated with increased participation in cancer screening. In Japan, it is recommended that individuals aged 40-74 years should undergo annual health check-ups; however, the compliance to this recommendation is approximately <50%. According to the national survey, individuals who do not undergo annual health check-ups are at a higher risk for cancer. However, to the best of our knowledge, no previous study has investigated the association between the use of health check-ups and the incidence rate of cancer. We hypothesised that not undergoing periodic health check-ups and/or less use of outpatient medical services are predictors for advanced cancer. METHODS To explore the relationship between health check-up or outpatient service utilisation and cancer incidence, this retrospective cohort study used data at two time points-baseline in 2014 and endpoint in 2017-from the National Health Insurance (NHI) claims and cancer registry. A multivariable logistic regression analysis was performed to investigate whether cancer diagnosis was associated with health check-up or outpatient service utilisation. RESULTS A total of 72,171 participants were included in the analysis. The results of the multivariable logistic regression showed that individuals who skipped health check-ups had a higher risk of cancer diagnosis (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.04-1.40). Moreover, not undergoing health check-ups increased the risk of advanced-stage cancer (OR, 1.78; 95% CI, 1.29-2.44). Furthermore, increased rate of outpatient service utilisation was negatively associated with advanced cancer diagnosis. CONCLUSIONS This is the first study reporting that not undergoing health check-ups is a predictor of cancer diagnosis and advanced cancer stage. Primary prevention strategies for NHI members who do not undergo health check-ups must be reassessed. Moreover, future research should examine secondary prevention strategies, such as health education and recommendations from health professionals to facilitate adequate utilisation of preventive health services.

Abstract
OBJECTIVE Clinical decision support systems (CDDSs) in the electronic medical record (EMR) have been implemented in primary care settings to identify patients due for cancer screening tests, while functioning as a real time reminder system. There is little known about primary care providers (PCPs) perspective or user acceptance of CDSS. The purpose of this study was to investigate primary care provider perceptions of utilizing CDSS alerts in the EMR to promote increased screening rates for breast cancer, cervical cancer, and colorectal cancer. METHODS An electronic survey was administered to PCPs in a Midwest Health Institution community internal medicine practice from September 25, 2019 through November 27, 2019. RESULTS Among 37 participants (9 NP/Pas and 28 MD/DOs), the NP/PA group was more likely to agree that alerts were helpful (50%; P-value = .0335) and the number of alerts (89%; P = .0227) in the EMR was appropriate. The NP/PA group also was more likely to find alerts straightforward to use (78%, P = .0239). Both groups agreed about feeling comfortable using the health maintenance alerts (MD/DO = 79%; NP/PA = 100%). CONCLUSION CDSSs can promote and facilitate ordering of cancer screening tests. The use of technology can promptly identify patients due for a test and act as a reminder to the PCP. PCPs identify these alerts to be a beneficial tool in the EMR when they do not interrupt workflow and provide value to patient care. More work is needed to identify factors that could optimize alerts to be even more helpful, particularly to MD/DO groups.

Intention for Screening Colonoscopy among Previous Non-Participants: Results of a Representative Cross-Sectional Study in Germany. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18084160. [PMID: 33920001 PMCID: PMC8070986 DOI: 10.3390/ijerph18084160] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 04/11/2021] [Accepted: 04/13/2021] [Indexed: 12/27/2022]
Abstract
Early detection of colorectal cancer has the potential to reduce mortality at population level. Colonoscopy is the preferred modality for colon cancer screening and prevention, but attendance rates are low. To exploit colonoscopy's preventive potential, it is necessary to identify the factors influencing uptake, especially among previous non-participants. This analysis of cross-sectional data involved 936 non-participants in screening colonoscopy aged 55 years or older in Germany. Differences between non-participants with and without future participation intentions were investigated in terms of socio-demographic factors, health status, attitudes and beliefs, and medical counselling. Logistic regression models were fitted to estimate associations between intention to participate and selected factors. Intention to participate was lower among women than among men. For both genders, intention to participate was positively associated with younger age. For women, higher socioeconomic status and counselling were positively associated with intention to participate. Men showed a positive association with favouring joint decision-making. The results draw attention to starting points for improving acceptance of and participation in screening colonoscopy. This includes good medical counselling and successful physician-patient communication, for which the information and communication skills of both medical professions and the general public should be strengthened. Gender differences should be considered.

Psychooncology 2020; 29:1237-1247. [PMID: 32539187 DOI: 10.1002/pon.5443] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 06/03/2020] [Accepted: 06/06/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To synthesise qualitative evidence related to barriers and facilitators of flexible sigmoidoscopy screening (FSS) intention and uptake, particularly within low socio-demographic uptake groups. FSS uptake is lower amongst women, lower socio-economic status (SES), and Asian ethnic groups within the United Kingdom (UK) and United States of America. METHODS A total of 12 168 articles were identified from searches of four databases: EMBASE, MEDLINE, PsycINFO and Web of Science. Eligibility criteria included: individuals eligible to attend FSS and empirical peer-reviewed studies that analysed qualitative data. The Critical Appraisal Skills Program tool evaluated the methodological quality of included studies, and thematic synthesis was used to analyse the data. RESULTS Ten qualitative studies met the inclusion criteria. Key barriers to FSS intention and uptake centred upon procedural anxieties. Women, including UK Asian women, reported shame and embarrassment, anticipated pain, perforation risk, and test preparation difficulties to elevate anxiety levels. Religious and cultural-influenced health beliefs amongst UK Asian groups were reported to inhibit FSS intention and uptake. Competing priorities, such as caring commitments, particularly impeded women's ability to attend certain FSS appointments. The review identified a knowledge gap concerning factors especially associated with FSS participation amongst lower SES groups. CONCLUSIONS Studies mostly focussed on barriers and facilitators of intention to participate in FSS, particularly within UK Asian groups. To determine the barriers associated with FSS uptake, and further understand how screening intention translates to behaviour, it is important that future qualitative research is equally directed towards factors associated with screening behaviour.

Abstract
Colorectal cancer (CRC) screening participation remains unacceptably low. This study investigated the emotion of disgust as a potential deterrent to intention to screen for CRC. The study utilised a convenience sample of individuals' 40-70 years of age to complete an online survey. Participants included 30 men and 118 women recruited between December 1, 2013 and March 31, 2014. Data on socio-demographics, health status, screening intentions and emotional barriers to bowel screening were collected via an on-line survey. Logistic regression analysis was utilised to investigate predictors of screening intention. Individuals were more likely to report intention to screen if they had prior screening experience, and reported fewer emotional concerns to screening for CRC. Results implicate disgust as a predictor of screening avoidance among participants. Specifically, higher reported faecal disgust was predictive of a 3% decrease in screening intention. This study was the first to empirically position disgust alongside other negative emotional states as an affective barrier to screening for CRC. Trait disgust sensitivity was not a reliable predictor of screening intention. This research suggests that anticipated faecal disgust may contribute to avoidance of screening for CRC.

Abstract
BACKGROUND Demand for a wide array of colorectal cancer screening strategies continues to outpace supply. One strategy to reduce this deficit is to dramatically increase the number of primary care physicians who are trained and supportive of performing office-based colonoscopies or flexible sigmoidoscopies. This study evaluates the clinical and economic implications of training primary care physicians via family medicine residency programs to offer colorectal cancer screening services as an in-office procedure. METHODS Using previously established clinical and economic assumptions from existing literature and budget data from a local grant (2013), incremental cost-effectiveness ratios are calculated that incorporate the costs of a proposed national training program and subsequent improvements in patient compliance. Sensitivity analyses are also conducted. RESULTS Baseline assumptions suggest that the intervention would produce 2394 newly trained residents who could perform 71,820 additional colonoscopies or 119,700 additional flexible sigmoidoscopies after ten years. Despite high costs associated with the national training program, incremental cost-effectiveness ratios remain well below standard willingness-to-pay thresholds under base case assumptions. Interestingly, the status quo hierarchy of preferred screening strategies is disrupted by the proposed intervention. CONCLUSIONS A national overhaul of family medicine residency programs offering training for colorectal cancer screening yields satisfactory incremental cost-effectiveness ratios. However, the model places high expectations on primary care physicians to improve current compliance levels in the US.

Abstract
Although health behavior theories postulate that risk perception should motivate colorectal cancer (CRC) screening, this relationship is unclear. This meta-analysis aims to examine the relationship between CRC risk perception and screening behavior, while considering potential moderators and study quality. A search of six databases yielded 58 studies (63 effect sizes) that quantitatively assessed the relationship between CRC risk perception and screening behavior. Most included effect sizes (75 %) reported a positive association between CRC risk perception and screening behavior. A random effects meta-analysis yielded an overall effect size of z = 0.13 (95 % CI 0.10-0.16), which was heterogeneous (I (2) = 99 %, τ(2) = 0.01). Effect sizes from high-quality studies were significantly lower than those from lower quality studies (z = 0.02 vs. 0.16). We found a small, positive relationship between CRC risk perception and reported screening behavior, with important identified heterogeneity across moderators. Future studies should focus on high quality study design.

Abstract
BACKGROUND Understanding the joint effects of insurance type and primary care physician density on stage at diagnosis is essential to elucidating the healthcare access and late-stage cancer relationship. PURPOSE To determine if the relationship between primary care physician density and odds of late-stage cancer are modified by insurance type at diagnosis. METHODS Case patients were Ohio adults diagnosed between 1996 and 2008 with cancer of one of the following sites: female breast, cervix, colon/rectum, lung/bronchus, melanoma of the skin, oral cavity and pharynx, or prostate (N=376,425). County-level physician density was obtained from the Ohio Department of Health. Multilevel logistic regression models estimated odds ratios of late-stage cancer diagnosis associated with increases in primary care physician density by insurance type. Analyses were conducted in 2014. RESULTS Decreases in late-stage diagnosis of cancers of the breast, prostate, melanoma of the skin, oral cavity and pharynx, or lung/bronchus associated with increases in primary care physician density were strongest among those with private insurance, whereas those with Medicare (prostate, oral cavity and pharynx, lung/bronchus), Medicaid (lung/bronchus), uninsured (prostate), and other/unknown (prostate, oral cavity and pharynx, lung/bronchus) did not benefit as greatly, or experienced significant increases in late-stage cancer diagnosis (other/unknown [female breast], Medicaid [melanoma of the skin], and uninsured [colon/rectum]). CONCLUSIONS As primary care physician density increases, those with private insurance consistently benefit the most in terms of late-stage cancer diagnosis, whereas those with several other insurance types experience flatter decreases or significantly higher odds of late-stage cancer diagnosis.

Abstract
BACKGROUND Limited data are available on the association between colorectal cancer (CRC) worry and CRC screening uptake, particularly in rural and underserved populations where there is an excess burden of CRC. METHODS Between September 2009 and March 2010, we conducted a cross-sectional study among a randomly selected sample of Appalachian Ohio residents aged 51-75 years (n= 1084). We also reviewed their medical records. Multivariable-adjusted models examined the association between CRC worry and screening by medical record review, assessed effect modification by CRC worry and determined the correlates of higher CRC worry. RESULTS Approximately 50% of participants were adherent to CRC screening guidelines. There was no significant association between higher CRC worry and screening adherence [odds ratio (OR) = 1.32, 95% confidence interval (CI): 0.86-2.02]. CRC worry did not modify the association between any covariate and screening adherence. Participants who were unemployed/disabled (OR = 2.15, 95% CI: 1.34-3.45) and had higher CRC risk perception (OR = 3.49, 95% CI: 2.19-5.56) had higher odds of moderate-to-extreme worry. CONCLUSIONS These findings highlight the need for meaningful exploration of why higher CRC worry is not associated with adherence to CRC screening, particularly in rural, medically underserved populations. Development and implementation of interventions to increase CRC screening in such areas is a significant public health priority.

Abstract
BACKGROUND Although the Centers for Medicare and Medicaid Services (CMS) denied coverage for screening computed tomography colonography (CTC) in March 2009, little is understood about whether CTC was targeted to the appropriate patient population prior to this decision. OBJECTIVE Evaluate patient characteristics and known relative clinical indications for screening CTC among patients who received CTC compared to optical colonoscopy (OC). DESIGN/PARTICIPANTS Cross-sectional study of all 10,538 asymptomatic Medicare beneficiaries who underwent CTC between January 2007 and December 2008, compared to a cohort of 160,113 asymptomatic beneficiaries who underwent OC, matched on county of residence and year of examination. MAIN MEASURES Patient characteristics and known relative appropriate and inappropriate clinical indications for screening CTC. KEY RESULTS CTC utilization was higher among women, patients > 65 years of age, white patients, and those with household income > 75 % (p = 0.001). Patients with relatively appropriate clinical indications for screening CTC were more likely to undergo CTC than OC including presumed incomplete OC (OR 80.7, 95 % CI 76.01-85.63); sedation risk (OR 1.11, 95 % CI 1.05-1.17); and chronic anticoagulation risk (OR 1.46, 95 % CI 1.38-1.54), after adjusting for patient characteristics and known clinical indications. Conversely, patients undergoing high-risk screening, an inappropriate indication, were less likely to receive CTC (OR 0.4, 95 % CI 0.37-0.42). Overall, 83 % of asymptomatic patients referred to CTC had at least one clinical indication relatively appropriate for CTC (8,772/10,538). CONCLUSION During the 2 years preceding CMS denial for screening, CTC was targeted to asymptomatic patients with relatively appropriate clinical indications for CTC/not receiving OC. However, CTC utilization was lower among certain demographic groups, including minority patients. These findings raise the possibility that future coverage of screening CTC might exacerbate disparities in colorectal cancer screening while increasing overall screening rates.

Abstract
Background Colonoscopy is widely regarded to be the gold standard for colorectal cancer (CRC) detection. Recent studies, however, suggest that the effectiveness of colonoscopy is mostly confined to tumors on the left side of the colon (descending, sigmoid, rectum), and that the technology has poor tumor detection for right-sided (cecum, ascending, transverse) lesions. A minimally invasive test that can detect both left-sided and right-sided lesions could increase the effectiveness of screening colonoscopy by revealing the potential presence of neoplasms in the right-sided “blind spot”. Methods We previously reported on a seven-gene, blood-based biomarker panel that effectively stratifies a patient’s risk of having CRC. For the current study, we assessed the effectiveness of the seven-gene panel for the detection of left- and right-sided CRC lesions. Results were evaluated for 314 patients with CRC (left-sided: TNM I, 65; TNM II, 57; TNM III, 60; TNM IV, 17; unknown, 9. right-sided: TNM I, 28; TNM II, 29; TNM III, 38; TNM IV, 12; unknown, 1 and including two samples with both left and right lesions) and 328 control samples. Blood samples were obtained prior to clinical staging and therapy. Most CRC subjects had localized disease (stages I and II, 58%); regional (stage III) and systemic (stage IV) disease represented 32% and 9%, respectively, of the study population. Results The panel detected left-sided (74%, 154/208) and right-sided (85%, 92/108) lesions with an overall sensitivity of 78% (215/316) at a specificity of 66% (215/328). Treatable cancer (stages I to III) was detected with left-sided lesion sensitivity of 76% (138/182) and right-sided sensitivity of 84% (80/95). Conclusion This seven-gene biomarker panel detected right-sided CRC lesions across all cancer stages with a sensitivity that is at least equal to that for left-sided lesions. This study supports the use of this panel as the basis for a patient-friendly, blood-based test that can be easily incorporated into a routine physical examination in advance of colonoscopy to provide a convenient companion diagnostic and a pre-screening alert, ultimately leading to enhanced CRC screening effectiveness.

Abstract
Purpose to evaluate the proportion of self-referred screening participants having various psychological barriers and the factors associated with these barriers. Methods A territory-wide bowel cancer screening centre sent an invitation via the media to all Hong Kong residents aged 50–70 years who were asymptomatic of CRC to join a free screening programme. Upon attendance they were requested to complete self-administered surveys on their perceived barriers of screening. Binary logistic regression analyses were used to evaluate the factors associated with these barriers. Results From 10,078 consecutive screening participants (mean age 57.5 years; female 56.4%) completed the surveys between May 2008 to September 2012. There were high proportions who agreed or strongly agreed with the following barriers: financial difficulty (86.0%), limited service accessibility (58.2%), screening-induced bodily discomfort (55.2%), physical harm (44.4%), embarrassment (40.1%), apprehension (38.8%) and time constraints (13.9%). From regression models, older participants (aged ≥56) were less likely to have these barriers (Adjusted odds ratio [AOR] ranged from 0.738 to 0.952) but they encountered more difficulties to access to screening services (AOR ranged from 1.141 to 1.371). Female subjects were more likely to encounter most of these barriers (AOR ranged from 1.188 to 2.179). Participants who were uncertain of the necessity of CRC screening for people aged ≥50 were more likely to report these barriers (AOR ranged from 1.151 to 1.671). Conclusion The proportions of perceptual barriers of CRC screening were high among these participants. Those with these associated factors should receive more thorough explanation of the screening test procedures.

Abstract
We conducted a randomized controlled trial among African-American patients attending a primary-care provider visit to compare efficacy of a computer-delivered tailored intervention to increase colorectal cancer (CRC) screening (n = 273) with non-tailored print material-an American Cancer Society brochure on CRC screening (n = 283). Health Belief Model constructs were used to develop tailored messages and examined as outcomes. Analysis of covariance models were used to compare changes between CRC knowledge and health belief scores at baseline and 1 week post-intervention. At 1 week, patients who received the computer-delivered tailored intervention had greater changes in CRC knowledge scores (P < 0.001), perceived CRC risk scores (P = 0.005), FOBT barriers scores (P = 0.034) and colonoscopy benefit scores (P < 0.001). Findings show that computer-delivered tailored interventions are an effective adjunct to the clinical encounter that can improve knowledge and health beliefs about CRC screening, necessary precursors to behavior change.

Abstract
PURPOSE We used the Surveillance Epidemiology and End Results (SEER)-Medicare database to explore the association between primary care and breast cancer outcomes. METHODS Using a retrospective cohort study of 105,105 female Medicare beneficiaries with a diagnosis of breast cancer in SEER registries during the years 1994-2005, we examined the total number of office visits to primary care physicians and non-primary care physicians in a 24-month period before cancer diagnosis. For women with invasive cancers, we examined the odds of diagnosis of late-stage disease, according to the American Joint Commission on Cancer (AJCC) (stages III and IV vs stages I and II), and survival (breast cancer specific and all cause) using logistic regression and proportional hazards models, respectively. We also explored whether including noninvasive cancers, such as ductal carcinoma in situ (DCIS), would alter results and whether prior mammography was a potential mediator of associations. RESULTS Primary care physician visits were associated with improved breast cancer outcomes, including greater use of mammography, reduced odds of late-stage diagnosis, and lower breast cancer and overall mortality. Prior mammography (and resultant earlier stage diagnosis) mediated these associations in part, but not completely. Similar results were seen for non-primary care physician visits. Results were similar when women with DCIS were included in the analysis. CONCLUSIONS Medicare beneficiaries with breast cancer had better outcomes if they made greater use of a primary care physician's ambulatory services. These findings suggest adequate primary medical care may be an important factor in achieving optimal breast cancer outcomes.

Abstract
OBJECTIVE Colorectal cancer screening (CRCS) should be a necessary part of gynecology (GYN) providers' preventive practices. The purpose of our study is to examine CRCS recommendations and adherence in this population. METHODS A questionnaire was administered to a prospective cohort of patients awaiting health maintenance exams at six academic and private gynecology offices. Patients reported demographics, CRC/breast/cervical screening adherence, CRCS recommendations, and future likelihood of CRCS. RESULTS A total of 461 women aged 51 years and older completed the questionnaire. Sixty-six percent of respondents were compliant with CRCS compared to 93% and 86% for breast and cervical cancer screening, respectively (p < 0.001). GYN providers recommended CRCS in 43% of patients. Sixty-three percent were planning to undergo future CRCS. On multivariable analysis, characteristics associated with CRCS adherence included (odds ratio, 95% confidence interval): older age (1.1 per year, 1.1-1.2), previous mammography (3.7, 1.4-9.7), family history (FH) of CRC/polyps (1.9, 1.0-3.4), friend with CRC (2.6, 1.5-4.7), and any doctor recommending CRCS (8.2, 4.6-14.7). CRCS rates were higher among patients who received a recommendation from a PCP (primary care provider) than from a GYN provider. Factors associated with intention to undergo CRCS include previous mammography (1.4, 4.2-12.0), any doctor recommendation (6.4, 3.7-11.0), and FH of CRC/polyps (3.5, 1.9-6.3). CRCS recommendations by both GYNs and PCPs had a greater impact on CRCS contemplation than those from a PCP or GYN alone. CONCLUSION In gynecology patients, having multiple providers recommend CRCS increases the likelihood of patients' intentions to undergo CRCS. However, CRCS compliance is primarily driven solely by PCP recommendations. Regardless, strategies must be in place to prompt gynecologists and nurse practitioners to discuss CRCS in eligible patients.

Abstract
Background Family history is a common risk factor for colorectal cancer (CRC), yet it is often underused to guide risk assessment and the provision of risk-appropriate CRC screening recommendation. The aim of this study was to identify from a patient perspective health care providers' current practice relating to: (i) assessment of family history of CRC; (ii) notification of "increased risk" to patients at "moderately/potentially high" familial risk; and (iii) recommendation that patients undertake CRC screening. Methods 1592 persons aged 56-88 years randomly selected from the Hunter Community Study (HCS), New South Wales, Australia were mailed a questionnaire. 1117 participants (70%) returned a questionnaire. Results Thirty eight percent of respondents reported ever being asked about their family history of CRC. Ever discussing family history of CRC with a health care provider was significantly more likely to occur for persons with a higher level of education, who had ever received screening advice and with a lower physical component summary score. Fifty one percent of persons at "moderately/potentially high risk" were notified of their "increased risk" of developing CRC. Thirty one percent of persons across each level of risk had ever received CRC screening advice from a health care provider. Screening advice provision was significantly more likely to occur for persons who had ever discussed their family history of CRC with a health care provider and who were at "moderately/potentially high risk". Conclusions Effective interventions that integrate both the assessment and notification of familial risk of CRC to the wider population are needed. Systematic and cost-effective mechanisms that facilitate family history collection, risk assessment and provision of screening advice within the primary health care setting are required.

Abstract
Colorectal cancer (CRC) is a major health problem worldwide. Although population-based CRC screening is strongly recommended in average-risk population, compliance rates are still far from the desirable rates. High levels of screening uptake are necessary for the success of any screening program. Therefore, the investigation of factors influencing participation is crucial prior to design and launches a population-based organized screening campaign. Several studies have identified screening behaviour factors related to potential participants, providers, or health care system. These influencing factors can also be classified in non-modifiable (i.e., demographic factors, education, health insurance, or income) and modifiable factors (i.e., knowledge about CRC and screening, patient and provider attitudes or structural barriers for screening). Modifiable determinants are of great interest as they are plausible targets for interventions. Interventions at different levels (patient, providers or health care system) have been tested across the studies with different results. This paper analyzes factors related to CRC screening behaviour and potential interventions designed to improve screening uptake.

Abstract
OBJECTIVE Compliance with colorectal cancer screening recommendations requires considerable conscious effort on the part of the individual patient, making an individual's decisions about engagement in screening an important contributor to compliance or noncompliance. The objective of this paper was to examine the effectiveness of individual-level behavior theories and their associated constructs in accounting for engagement in colorectal cancer screening behavior. METHODS We reviewed the literature examining constructs from formal models of individual-level health behavior as factors associated with compliance with screening for colorectal cancer. All published studies examining one or more constructs from the health belief model, theory of planned behavior, transtheoretical model, or social cognitive theory and their relation to screening behavior or behavioral intentions were included in the analysis. RESULTS By and large, results of studies supported the theory-based predictions for the influence of constructs on cancer screening behavior. However, the evidence base for many of these relations, especially for models other than the health belief model, is quite limited. CONCLUSIONS Suggestions are made for future research on individual-level determinants of colorectal cancer screening.

Abstract
Narratives from similar others may be an effective way to increase important health behaviors. In this study, we used a narrative intervention to promote colorectal cancer screening. Researchers have suggested that people may overestimate barriers to colorectal cancer screening. We recruited participants from the US, ages 49-60 who had never previously been screened for colorectal cancer, to read an educational message about screening for the disease. One-half of participants were randomly assigned to also receive a narrative within the message (control participants did not receive a narrative). The narrative intervention was developed according to predictions of affective forecasting theory. Compared to participants who received only the educational message, participants who received the message along with a narrative reported that the barriers to screening would have less of an impact on a future screening experience. The narrative also increased risk perception for colorectal cancer and interest in screening in the next year.

Abstract
Colorectal cancer (CRC) accounts for 9% of all new cancer cases worldwide and affects over 1 million people each year. Screening can reduce the mortality associated with the disease, yet participation rates are suboptimal. Compliers with CRC screening are less deprived; they have higher education than noncompliers and tend to be male, white and married. Likely reasons for nonparticipation encompass several 'modifiable' factors that could be targeted in interventions aimed at increasing participation rates. Successful intervention strategies include organizational changes, such as increasing access to fecal occult blood test (FOBT) kits, providing reminders to healthcare providers or users about screening opportunities, and educational strategies to improve awareness and attitudes towards CRC screening. Multifactor interventions that target more than one level of the screening process are likely to have larger effects. The biggest challenge for future research will be to reduce inequalities related to socio-economic position and ethnicity in the uptake of screening.

Abstract
OBJECTIVE We measured the perceived risk for developing gastric cancer and investigated how a range of socio-demographic, lifestyle, health, and psychological factors were associated with risk perception in a population-based sample in Korea. METHODS This study was based on the 2006 Korean National Cancer Screening Survey conducted by the National Cancer Center, in which trained interviewers met face-to-face with participants selected by a nationally representative random sampling. The participants included 1673 adults, aged 40 years or older, who had not previously been diagnosed with cancer. Simple and multiple ordinal regression were used to determine the associations between perceived risk and socio-demographic, lifestyle, health, and psychological factors. RESULTS Almost half of the subjects (48.3%) thought their chance of developing gastric cancer was lower than that of other men or women of the same age. A higher level of worry concerning gastric cancer was strongly associated with a higher perceived risk for gastric cancer development. Those who drink alcohol two or more days per week, and who are unmarried all perceived their risk as being higher. However, those without a previous gastric cancer screening, a personal history of gastric disease, or a good overall health status had a lower perceived risk for gastric cancer development. CONCLUSION This study found comparative optimism about the risk for developing gastric cancer in a Korean population. It is necessary to increase people's ability to accurately perceive their risk for cancer.

Provider recommendation for colorectal cancer screening: examining the role of patients' socioeconomic status and health insurance. Cancer Epidemiol 2009; 33:207-11.

Abstract
BACKGROUND Provider recommendation for colorectal cancer (CRC) screening test has been shown as a strong predictor of patients' decision to be screened. Evidence of factors associated with provider recommendation remains limited and inconsistent. The present study sought to examine the association between provider recommendation for colorectal cancer screening and patients' socioeconomic status (SES) and insurance status using national survey data for 2005. METHODS Analyses were based on 2948 adult aged 50 and older who participated in the 2005 Health Information National Trend Survey (HINTS). Multivariate logistic regression models were used to determine whether the indicators of SES (income and educational level) and insurance status have any impact on provider recommendation. RESULTS Our study found a strong association between recall of health care provider recommendation and reported recent screening testing after controlling for other patient characteristics. When all the study population were included in the analysis, those who had lower than high school education and high school graduates were less likely to have received provider recommendation than those with higher than high school education (OR=0.49; 95%CI=0.32-0.73 and OR=0.60; 95%CI=0.47-0.78 respectively). Income and insurance were not significant predictors. Education remained significantly associated with provider recommendation when only those who had made one or more medical visits in the past year were included in the analyses. CONCLUSIONS Patient's educational level--but not income or insurance status--was related to provider recommendation for CRC screening. To increase awareness of colorectal cancer risks and the benefit of screening, health care providers need to make a concerted effort to recommend colorectal cancer screening to all relevant patients, regardless of socioeconomic status and other personal characteristics.

Abstract
OBJECTIVE This study examines the correlates of: (1) health care provider recommendation of CRC testing; (2) provider scheduling for recommended CRC testing using sigmoidoscopy, colonoscopy, or double-contrast barium enema; and (3) adherence to CRC scheduling among underserved minority populations. METHODS Medical record and schedule logbook reviews and interviewer-administered surveys. SETTING Large urban safety-net, outpatient primary care setting in Los Angeles County. PARTICIPANTS 306 African-American and Latino patients aged 50 years and older. RESULTS A vast majority of minority patients do not receive standard CRC testing in urban safety-net primary care settings. Of those patients who were actually scheduled for sigmoidoscopy or colonoscopy, almost half completed the procedure. Completing CRC testing was associated with marital status, co-morbid chronic physical conditions, number of risk factors for colorectal cancer, and lower perceived barriers to CRC testing. CONCLUSION Effective interventions to reduce CRC mortality among underserved minority populations require an integrated approach that engages patients, providers, and health care systems. PRACTICE IMPLICATIONS Designing interventions that (1) increase physician-patient communications for removing patients' perceived barriers for CRC testing and (2) promote a non-physician-based navigator system that reinforces physicians' recommendation are strongly recommended.

Abstract
BACKGROUND Consumer-directed health plans are increasingly common, yet little is known about their impact on physician decision-making and preventive service use. OBJECTIVE To determine how patients' deductible levels and socioeconomic status may affect primary care physicians' recommendations for colorectal cancer screening. DESIGN, SETTING, AND PARTICIPANTS Screening recommendations were elicited using hypothetical vignettes from a national sample of 1,500 primary care physicians. Physicians were randomized to one of four vignettes describing a patient with either low or high socioeconomic status (SES) and either low- or high-deductible plan. Bivariate and multivariate analyses were used to examine how recommendations varied as a function of SES and deductible. OUTCOME MEASURES Rates of recommendation for home fecal occult blood testing, sigmoidoscopy, colonoscopy, and inappropriate screening, defined as no screening or office-based fecal occult blood testing. RESULTS A total of 528 (49%) eligible physicians responded. Overall, 7.2% of physicians recommended inappropriate screening; 3.2% of patients with high SES in low-deductible plans received inappropriate screening recommendations and 11.4% of patients with low SES in high-deductible plans for an adjusted odds ratio of 0.22 (0.05-0.89). The odds of a colonoscopy recommendation were over ten times higher (AOR 11.46, 5.26-24.94) for patients with high SES in low-deductible plans compared to patients with low SES in high-deductible plans. Funds in medical savings accounts eliminated differences in inappropriate screening recommendations. CONCLUSIONS Patient SES and deductible-level affect physician recommendations for preventive care. Coverage of preventive services and funds in medical savings accounts may help to mitigate the impact of high-deductibles and SES on inappropriate recommendations.

Abstract
BACKGROUND Colorectal cancer screening (CRCS) has been demonstrated to be effective and is consistently recommended by clinical practice guidelines. However, only slightly over half of all Americans have ever been screened. Patients cite physician recommendation as the most important motivator of screening. This study explored the barriers of and facilitators to physician recommendation of CRCS. METHODS A 3-component qualitative study to explore the barriers of and facilitators to physician recommendation of CRCS: in-depth, semistructured interviews with 29 purposively sampled, community- and academic-based primary care physicians; chart-stimulated recall, a technique that utilizes patient charts to probe physician recall and provide context about the barriers of and facilitators to physician recommendation of CRCS during actual clinic encounters; and focus groups with 18 academic primary care physicians. Grounded theory techniques of analysis were used. RESULTS All the participating physicians were aware of and recommended CRCS. The overwhelmingly preferred test was colonoscopy. Barriers of physician recommendation of CRCS included patient comorbidities, prior patient refusal of screening, physician forgetfulness, acute care visits, lack of time, and lack of reminder systems and test tracking systems. Facilitators to physician recommendation of CRCS included patient request, patient age 50-59, physician positive attitudes about CRCS, physician prioritization of screening, visits devoted to preventive health, reminders, and incentives. CONCLUSION There are multiple physician, patient, and system barriers to recommending CRCS. Thus, interventions may need to target barriers at multiple levels to successfully increase physician recommendation of CRCS.

Abstract
Colorectal cancer (CRC) screening is strongly supported by evidence and widely recommended, but remains underutilized. This study reports the prevalence of CRC diagnostic testing and CRC screening in three racial/ethnic groups attending the same primary care clinic. A cross-sectional survey was conducted to elicit past history of CRC testing, including test type, indication and timing. A comparable number of African American, Hispanic and non-Hispanic white patients aged 50-80 were recruited. 560 surveys were completed: mean age was 63.4 years, 64% reported minority race/ethnicity, and 96.8% had insurance. Overall, 62.5% [95% CI: 58.5%, 66.5%] of patients were current with any type of CRC test, when diagnostic and screening procedures were included. However, 48.6% [95% CI: 44.5%, 52.7%] of the sample was current with CRC screening, when only procedures performed for screening in asymptomatic patients were included. Patients least likely to be current with testing were those of minority race/ethnicity (48.2% of Hispanics, 56.7% of African Americans and 67.5% of non Hispanic whites, p < 0.05), younger age, (57.6% of those aged 50-64, and 71.4% of those aged 65-80, p < 0.005), and those with private insurance alone (56.0% private, 67.7% public and 68.1% mixed, p < 0.05). Our findings indicate that racial/ethnic and age related disparities in CRC screening exist even in a patient population that has the same source of health care and no differences in insurance status. These results underline the need for providers to emphasize CRC screening in their practices to minority patients and those younger than 65 years of age.

Abstract
Since 1998 in Japan, guidelines for cancer screening programs have been developed and revised by a research group funded by the Ministry of Health, Labour and Welfare. However, little is known about health professionals' awareness of and adherence to the cancer screening guidelines. Surveys were conducted by mailing questionnaires to two target groups of health professionals: local government officers of municipal cancer screening programs of 3327 municipalities in 47 prefectures (local government officers group; n = 3327) and councilors of an academic society dealing with a mass survey of gastroenterological cancer (expert group; n = 195). The questionnaire contained questions dealing with: (1) awareness of and adherence to the cancer screening guidelines published in 2001, and (2) basic knowledge of and attitude towards cancer screening. We compared the responses of the two groups. The response rate in both groups was approximately 65%. Over 70% of the respondents were aware of the cancer screening guidelines. However, 20% of the local government officers and 35% of the experts thought that non-recommended methods could be used for population-based screening. Fifty-six percent of the local government officers and 76% of the experts responded that there was no problem with using non-recommended methods for opportunistic screening. Almost all health professionals believed that screening was 'almost always a good idea'. Although the two groups' backgrounds differed, both did not sufficiently understand the evidence-based approach for cancer screening. To properly conduct evidence-based cancer screening, it is necessary that health professionals have an appropriate understanding of the guidelines.

Abstract
BACKGROUND A few previous studies have shown that men were more likely than women to be screened for colorectal cancer (CRC). METHODS The 2000 National Health Interview Survey (NHIS) was administered to 32,374 adults > or = 18 years of age. Participants were asked if they ever had a sigmoidoscopy or colonoscopy and if they ever had a home fecal occult blood test (FOBT). Men and women > or = 50 years were eligible for analysis. Participants were considered to be current in testing if they reported sigmoidoscopy in the last 5 years, colonoscopy in the last 10 years, or home FOBT in the last 1 year. RESULTS Overall, 62.9% of adults had ever had CRC testing, and 37.1% were current for testing. Compared to older men, a greater proportion of older women were not current for testing (62.6% for women vs. 56.7% for men > 75 years). In multivariate analysis, women were not less likely than men to be current in CRC testing (OR 0.98, 95% CI 0.88-1.08). When compared with white women, black women were less likely to be current for CRC screening (OR 0.79, 95% CI 0.65-0.95). CONCLUSIONS CRC screening is underused. Targeting interventions to improve CRC screening for all appropriate patients will be important.

Abstract
BACKGROUND Most studies examining factors associated with colorectal cancer (CRC) screening (CRCS) are cross-sectional and thus temporal relationships cannot be determined. Furthermore, less attention has been paid to psychosocial predictors of CRCS. We examined both cross-sectional correlates of prior CRCS and predictors of prospective CRCS initiation and maintenance during The Next Step Trial, a 2-year worksite behavioral intervention to promote regular CRCS and dietary change. METHOD The sample included 2,693 White male automotive workers at increased occupational risk for, but no history of, CRC who completed a baseline survey. Stratified analyses were conducted for three dependent variables (prior CRCS, CRCS initiation, and CRCS maintenance). We also assessed prior CRCS as a moderator in prospective analyses. Multivariable logistic regression analyses with generalized linear mixed models were used to adjust for cluster sampling. RESULTS Except for education, cross-sectional correlates of prior CRCS including older age, family history of CRC or polyps, personal history of polyps, self-efficacy, family support, and intention were also significant prospective predictors of increased CRCS during the trial. Despite differences in the patterns of association for CRCS initiation and maintenance in stratified analyses, the only associations with prospective CRCS that were significantly moderated by prior CRCS were family history and CRCS availability. CONCLUSIONS Correlates of prior CRCS that also were prospective predictors of CRCS may be suitable targets for intervention. Additionally, intervention messages addressing psychosocial constructs may be relevant for both CRCS initiation and maintenance. However, studies with more diverse samples are needed to replicate the results reported here.

Abstract
BACKGROUND AND STUDY AIM Flexible sigmoidoscopy (FS) is a feasible examination technique and a suitable tool for population-based screening, but very little is known about determinants of endoscopic screening participation. The aim of this study was to determine the acceptance rate and the factors influencing the decision of participating in a screening program for patients in an outpatient clinic. MATERIALS AND METHODS In this prospective study, a colorectal cancer screening by FS was offered to 631 patients older than 40 years. Three strategies were available, (1) to have the endoscopy on the same day, (2) to make an appointment for another day, or (3) to take time to think about if they wanted the procedure. The reasons for refusal of the FS were documented. RESULTS 419 of the 631 (66.4%) patients had no interest to take part in the screening program during their outpatient visit. Two hundred twelve (33.6%) patients were primarily interested on FS, but only 110 of them were finally examined. In total, 102 patients did not make an appointment for FS or did not appear for the endoscopy. The participation rate was therefore 17.4% (110/631) of all patients. Of the patients who agreed to receive an on-site examination, 78.3% were examined compared to 18.8% of patients who fixed the appointment for another day or after taking time to reflect upon the FS procedure. More male than female patients accepted the FS screening. Recommended colonoscopy was finally performed in 76%. Thirty-three polyps were found during the screening program of which 18 were larger than 0.5 cm. No CRC was detected. All patients agreed to repeat the FS every 5 years. CONCLUSIONS This study demonstrates that a screening examination will be most likely performed if it is done as an on-site examination. In contrast, the participation rate is low if the patient has to make an appointment by himself. Acceptance of FS screening is also dependent on the patient's gender and family history of cancer. Additional strategies are needed to further improve participation.

Abstract
BACKGROUND In 1998 the Veterans Administration mandated an externally monitored targeted colon cancer screening rate that was expected to result in earlier cancer detection and improved patient survival. The effectiveness of the protocol was evaluated in a retrospective case series at a tertiary care Veterans Administration Hospital that included all patients with the diagnosis of colon cancer between 1991 and 2003. METHODS Tumor stage, tumor location, and patient survival data were recorded and compared to National Cancer Data Base (NCDB) benchmarks. RESULTS The study facility had a greater percentage of early cancers and fewer later stage cancers than the NCDB benchmark. Overall survival was better for the VA cohort compared to NCDB (all-cause 5-year survival: VA, 0.72; NCDB, 0.47. p < or = .001). CONCLUSIONS The VA facility had a significantly greater percentage of early cancers and fewer stage III or IV cancers compared to a national benchmark and significantly improved survival compared to the national benchmark.

Abstract
BACKGROUND Colorectal cancer is the second leading cause of cancer-related death in the United States, yet recommended screenings are not delivered to most people. This assessment of colorectal cancer screening's value to the U.S. population is part of the update to a 2001 ranking of recommended clinical preventive services found in the accompanying article. This article describes the burden of disease prevented and cost-effectiveness as a result of offering patients a choice of colorectal cancer screening tools. METHODS Methods used were designed to ensure consistent estimates across many services and are described in more detail in the companion articles. In a secondary analysis, the authors also estimated the impact of increasing offers for colorectal cancer screening above current levels among the current cross-section of adults aged 50 and older. RESULTS If a birth cohort of 4 million were offered screening at recommended intervals, 31,500 deaths would be prevented and 338,000 years of life would be gained over the lifetime of the birth cohort. In the current cross-section of people aged 50 and older, 18,800 deaths could be prevented each year by offering all people in this group screening at recommended intervals. Only 58% of these deaths are currently being prevented. In year 2000 dollars, the cost effectiveness of offering patients aged 50 and older a choice of colorectal cancer screening options is $11,900 per year of life gained. CONCLUSIONS Colorectal cancer screening is a high-impact, cost-effective service used by less than half of persons aged 50 and older.

Abstract
BACKGROUND This study examined trends in the numbers of double contrast barium enemas, flexible sigmoidoscopies, and colonoscopies and trends in the choices of colorectal cancer screening service providers. METHODS Descriptive statistics were used to examine Medicare and Tricare data for the years 1999 to 2001. RESULTS The total volume of procedures increased 5% and 14%, respectively, in Tricare and Medicare. Tricare and Medicare, respectively, saw 32% and 33% reductions in barium enemas and 28% and 41% reductions in flexible sigmoidoscopies. Colonoscopies increased by 45% and 34% in Tricare and Medicare, respectively. Gastroenterologists provided the majority of colonoscopies for both groups each year. CONCLUSIONS The volume of colonoscopies increased from 1999 to 2001 for both groups while the volumes of barium enemas and flexible sigmoidoscopies decreased. Gastroenterologists appear to be the preferred providers of colonoscopies.

Abstract
Colorectal cancer (CRC) is the most commonly diagnosed cancer among Chinese Americans and is the third leading cause of cancer death in this population. The objectives of this study were to determine the rates of CRC screening (via fecal occult blood test (FOBT), flexible sigmoidoscopy (FSIG), and colonoscopy) among Chinese Americans and predictors of utilizing these screening procedures. Participants (N = 206) completed a self-administered questionnaire assessing cancer screening behaviors and beliefs about perceived risk of developing cancer and treatment efficacy. A series of logistic regressions indicated that physician recommendation to obtain CRC screening significantly predicted whether Chinese Americans undergo FOBT, FSIG, or colonoscopy screening (p < 0.001). Acculturation and perceived risk of developing CRC did not predict obtaining any of the screening procedures. FOBT was the most commonly reported screening method used by respondents (65%), followed by FSIG (54%) and colonoscopy (49%). These findings highlight the need to make physicians more aware of the impact their recommendations have in determining CRC screening behavior among Chinese Americans.

Abstract
BACKGROUND Few studies have examined lack of physician recommendation and other reasons for under-utilization of colorectal cancer (CRC) screening in the Medicare population. METHODS Data from a telephone survey conducted in 2001 in a random sample of Medicare consumers residing in North and South Carolina were used to examine barriers to CRC screening, focusing on consumers' reports of receiving a physician's recommendation to obtain CRC screening and reasons for not being screened. Analyses were restricted to respondents with no history of CRC (n = 1901). Descriptive statistics were used to characterize respondents' CRC screening status, receipt of a physician's recommendation for screening, and reasons for not being screened. Logistic regression modeling was used to examine factors associated with receiving a physician recommendation for fecal occult blood test, sigmoidoscopy, colonoscopy, any endoscopy, and any CRC test. RESULTS Thirty-one percent of Medicare consumers had never been tested for CRC, and 18% had been tested but were not current with Medicare-covered intervals. Overall, 28% reported not receiving a physician recommendation for screening. Predictors of receiving a physician recommendation included sociodemographic (younger age, white race, more education), health status (increased CRC risk, comorbidity), and healthcare access (had a routine/preventive care visit in the past 12 months) factors. Lack of knowledge/awareness and the physician not ordering the test were commonly cited reasons for not having CRC tests. CONCLUSIONS Colorectal cancer screening was under-utilized by Medicare consumers in two states, and lack of physician recommendation was an important contributing factor. Providing a benefit under the Medicare program does not ensure its widespread use by consumers or their physicians.

Abstract
BACKGROUND Psychosocial constructs are widely used to predict colorectal cancer screening and are targeted as intermediate outcomes in behavioral intervention studies. Reliable and valid instruments for measuring general colorectal cancer screening psychosocial constructs are needed; yet, few studies have conducted psychometric analyses. This study replicated a five-factor structure for 16 theory-based, general colorectal cancer screening items measuring salience and coherence, cancer worries, perceived susceptibility, response efficacy, and social influence. In addition, we examined factorial invariance across race and sex. METHODS African American and Caucasian patients (n = 1,413) attending an urban, primary care clinic were included in this study. These individuals completed a baseline survey as part of a colorectal cancer screening intervention trial. Single and multigroup confirmatory factor analyses using maximum-likelihood estimation were done. RESULTS The five-factor general colorectal cancer screening model provided excellent fit and was invariant across race-sex subgroups. CONCLUSIONS The findings of invariance across sex and race subgroups support the use of these scales to measure group differences.

Abstract
BACKGROUND Colorectal cancer (CRC) ranks third of all cancer mortalities in Hong Kong. CRC screening can reduce mortality. However, participation in the CRC screening program depends on the knowledge and attitude of the population. The aim of this study is to investigate the knowledge and attitude towards CRC screening in the Hong Kong population. METHODS One thousand and thirty-three patients were interviewed by telephone survey. Knowledge and attitudes were assessed by using questionnaires. RESULTS Only 8.9% of the respondents were able to mention that CRC was the second commonest cancer cause of death; 4.5% believed they would have a higher chance of developing CRC as compared to other cancers, and 7.4% could mention one of the screening methods. Approximately half (50.3%) were unable to identify any available screening venue. Approximately one-third (29.5%) indicated that they would definitely join a free CRC screening program, but the percentage dropped to 7.9% when a paid screening program was offered. Some (30.4%) of the respondents had the wrong impression that they did not require CRC screening because they were asymptomatic. Multivariate analysis showed that the independent predictor for participating in free screening was the concern level of getting CRC, while that for a paid screening program was a positive family history of CRC and the concern level. The concern level was dependent on a positive family history and knowledge of CRC. CONCLUSION The general population in Hong Kong had deficient knowledge of CRC and screening. Education on the impact of CRC and beneficial effects of CRC screening should be offered before launching a CRC screening program.

Abstract
BACKGROUND Barriers to colorectal cancer (CRC) screening are not well understood. OBJECTIVES We sought to compare barriers to CRC screening reported by primary care physicians (PCPs) and by average-risk adults, and to examine characteristics of average-risk adults who identified lack of provider recommendation as a major barrier to CRC screening. RESEARCH DESIGN This was a comparative study using data from the 1999-2000 Survey of Colorectal Cancer Screening Practices and the 2000 National Health Interview Survey (NHIS). SUBJECTS We recruited nationally representative samples of PCPs (n= 1235) from the SCCSP and average-risk adults (n = 6497) from the NHIS. MEASURES We measured barriers to CRC screening identified by PCPs and average-risk adults who were not current with screening. RESULTS Both PCPs and average-risk adults identified lack of patient awareness and physician recommendation as key barriers to obtaining CRC screening. PCPs also frequently cited patient embarrassment/anxiety about testing and test cost/lack of insurance coverage, but few adults identified these as major barriers. Of adults not current with testing, those who had visited a doctor in the past year or had health insurance were more likely to report lack of physician recommendation as the main reason they were not up-to-date compared with their counterparts with no doctor visit or health insurance. Only 10% of adults not current with testing and who had a doctor visit in the past year reported receiving a screening recommendation. CONCLUSIONS A need exists for continued efforts to educate the public about CRC and the important role of screening in preventing this disease. Practice-based strategies to systematically prompt health care providers to discuss CRC screening with eligible patients also are required.

Abstract
This cross-sectional survey explored the association between functional health literacy and knowledge of, beliefs and attitudes about, and reported usage of colorectal cancer screening tests. The results indicate that functional health literacy, as assessed by the Short Test of Functional Health Literacy in Adults (STOFHLA), is not an independent predictor of colorectal cancer screening knowledge, beliefs, attitudes, or behavior. Latino ethnicity and education, however, often predicted screening responses, suggesting that efforts to improve communication about colorectal cancer screening with Latino patients and patients with low education clearly are needed to reduce the disparities in awareness and utilization of colorectal cancer screening tests. This study also explored influences on intended screening behavior. Physician recommendation was found to be a powerful motivator of intention to undergo colorectal cancer screening regardless of literacy level, indicating that interventions aimed at increasing physician recommendation of colorectal cancer screening may be an effective way of increasing screening rates.

Abstract
BACKGROUND In comparison to the United States, Maryland is facing a significantly higher burden of colorectal cancer incidence and mortality. The primary objective of this study was to determine the predictors of colorectal cancer screening use in Maryland. METHODS We performed secondary analyses on Maryland Cancer Survey 2002 data from 2994 respondents to investigate important predictors for individual colorectal cancer screening tests. CRC screening outcomes were defined as (1) FOBT within the past year, (2) sigmoidoscopy within the past 5 years, or (3) colonoscopy within the past 10 years. RESULTS We found that clinician recommendation for a screening test is the best predictor in both age categories (50-64 years and 65+ years); it is a very strong indicator and consistently improves the odds of use by a factor of at least 8 for any screening test. CONCLUSIONS There remains a great need for improved colorectal cancer screening in Maryland. According to our results, it is clear that the most influential way to improve overall colorectal cancer screening for each test and both age groups is to increase clinician recommendation for these tests.

Abstract
BACKGROUND The prevalence of colon cancer screening is nationally low. The relative contribution of patient factors and physician counseling patterns to the low prevalence of screening is unclear. METHODS We used multivariable analysis to examine the prevalence of colon cancer screening nationally and the reasons for this low prevalence using data from the 2000 National Health Interview Survey, a nationally generalizable survey of US households. RESULTS Among 11,427 respondents to the Cancer Control Supplement, 16% reported annual fecal occult blood testing (FOBT) and 29% reported having undergone a sigmoidoscopy in the last 5 years or a colonoscopy in the last 10 years. After adjusting for age, sex, body mass index (BMI), healthcare access, and region of the country, Hispanics were less likely to undergo FOBT [OR 0.7 (95% CI 0.6-0.9)] and sigmoidoscopy or colonoscopy [OR 0.8 (95% CI 0.7-0.9)] compared to Whites. Respondents with lower education levels were also less likely to undergo screening. These factors were not associated with being less adherent to physician recommendations for screening. Nevertheless, non-Whites and those less educated were less likely to receive counseling from their health provider about colon cancer screening. Among respondents who did not undergo FOBT, 64% were unaware they needed the test; only 2% cited pain and discomfort as a deterrent, but 94% were not counseled by their physician about the test. Among those who did not undergo sigmoidoscopy or colonoscopy, 72% were unaware that they needed the test and only 1% was deterred by pain and discomfort; 92% were not counseled by their physician. CONCLUSION The low prevalence of screening for colorectal cancer appears to be due to lack of awareness and inadequate provider counseling rather than poor patient acceptance for screening. Systematic counseling about colorectal cancer screening will likely improve screening rates and reduce disparities by race/ethnicity and education.

Abstract
BACKGROUND Flexible sigmoidoscopy (FS) is an effective method to prevent and reduce mortality from colorectal carcinoma (CRC). Incomplete depth of insertion (IDI) during FS may result in missed polyps and carcinomas. To determine whether it is possible to predict IDI, the authors analyzed factors that affected the depth of insertion in FS. METHODS For the current study, FS results were recorded prospectively over a 5-year period. A questionnaire was administered to the patient by the investigator prior to FS to collect data, including age, gender, weight, comorbid illnesses, history of prior abdominal and pelvic surgeries, family history of colon carcinoma or polyps, and prior FS or colonoscopies. The depth of insertion of the flexible sigmoidoscope from the anal verge, which was defined as the reading on the outside of the instrument at its maximal insertion, was measured in centimeters. IDI was defined as a depth of insertion < 50 cm. Classification and regression tree analysis was used to develop a model that included variables predictive of IDI. RESULTS The best classification tree included gender, age < 69 years (in women), and a history of hysterectomy. Men had a < 5% risk of an IDI and women age < 69 years without a hysterectomy fared as well (6.6%). Older women and younger women who underwent hysterectomy had higher rates of IDI (29.2% and 22.3%, respectively.) CONCLUSIONS The authors developed a model based on age, gender, and hysterectomy status that, after further validation, may be useful for predicting which patients likely will have an incomplete examination. In those patients who have a high probability of IDI, the choice can be made to offer colonoscopy or perform FS under sedation, with analgesia, or with the help of distraction techniques.

Abstract
BACKGROUND AND AIMS Periodic colonoscopy is an effective means of reducing the incidence and mortality of colorectal cancer in individuals with a family history of the disease. The aims of this study were to determine the degree of compliance and to identify the factors related significantly to noncompliance with periodic screening in this high-risk population. METHODS A total of 178 individuals who had undergone genetic counseling for colorectal cancer between 1986 and 1998 and who had been advised to undergo periodic screening because of familial colorectal cancer (FCRC) or hereditary nonpolyposis colorectal cancer (HNPCC) were invited to complete a self-report questionnaire on psychosocial issues and screening experiences. Compliance data were derived from medical records and via self-report. RESULTS A total of 149 individuals (84%) participated in the study. Noncompliance with screening advice was rare (in 3% of cases), but significant delays (more than 1 year) in undergoing screening were observed in approximately 25% of the cases. The number of perceived barriers to screening (eg, discomfort, embarrassment) was the only variable related significantly to noncompliance/screening delay (odds ratio, 1.2; 95% confidence interval, 1.1-1.3). Use of sedatives during the procedure and receipt of a reminder letter seemed to facilitate better compliance. CONCLUSIONS Although few high-risk individuals abstain from screening entirely, approximately one in 4 deviates significantly from the recommended frequency of screening. Increased compliance may be achieved by reducing the discomfort and embarrassment associated with the procedure and by the use of reminder letters.

Abstract
This study explored: (1) patient characteristics associated with physician recommendation for colorectal cancer (CRC) screening and patient adherence to recommendation, and (2) the combined effect of recommendation and adherence on CRC testing, broadly defined. Data were from the 1999 MA BRFSS and a call-back survey of 869 BRFSS participants, age 50 and older. Logistic regression was used to identify correlates of recommendation, adherence, and testing. Patient-physician factors were positively associated with recommendation, adherence and testing. Inadequate health insurance was negatively associated with recommendation (OR = 0.45, 95% CI = 0.27-0.78) and testing (OR = 0.64, 95% CI = 0.38-1.1). Men were not more likely to be recommended (OR = 1.1, 95% CI = 0.78-1.5), but were more likely to adhere (OR = 1.9, 95% CI = 1.2-2.0) and to be tested (OR = 1.4, 95% CI = 1.0-1.9). There were gender differences in recommendation when considering health and risk factor measures. Research is needed to understand differences in recommendation and adherence. Greater encouragement and follow-through may be needed for groups less likely to adhere.

Abstract
The expectation of pain is a statistically significant factor negatively affecting patient compliance with current screening flexible sigmoidoscopy recommendations. Numerous pain reduction modalities have been studied with limited success. Transcutaneous electrical nerve stimulation (TENS) has been used to treat pain of various origins. The purpose of this pilot study was to determine the efficacy of TENS in reducing discomfort experienced during screening flexible sigmoidoscopy.A double-blind study was conducted in which 90 subjects were randomized to receive TENS, sham TENS, or control (standard care). The same pulse frequency and intensity were used for all subjects in the TENS group. Subjects completed preprocedural and postprocedural questionnaires, and the endoscopist completed a postprocedural questionnaire. A slight, but statistically insignificant (p =.526) reduction in the mean pain score reported by the TENS group was noted when compared with the sham TENS and control groups (2.00, 2.27, and 2.23 respectively). In light of the fact that only one pulse frequency and intensity of the TENS intervention were used in this study, further study with this safe and cost-effective modality is warranted.

Abstract
The primary objective of this study was to determine the prevalence of colorectal cancer (CRC) screening among eligible patients in a large medical practice. A secondary objective was to compare CRC screening rates obtained from medical records with physician self-reported CRC screening recommendation. We conducted a retrospective record review of 214 patients ages > or = 50 years of a large multispecialty medical organization in Houston, Texas, for receipt of fecal occult blood test (FOBT), flexible sigmoidoscopy (SIG), and/or colonoscopy (COL). We estimated prevalence using two definitions: (a) FOBT in past year or SIG in past 5 years or COL in past 10 years; and (b) FOBT in past year and SIG in past 5 years or COL in past 10 years. Age, gender, race/ethnicity, family history, number of chronic conditions, and index visit were independent variables. Contingency table and logistic regression analysis were used to test for associations between outcomes and independent variables. Our study population was 48% male with a mean age of 63 years (range: 53-84 years). One-quarter of the records showed FOBT by 3-day kit (51 of 214) and 27% by digital rectal exam (57 of 214). SIG was recorded in 32% of records. Half (54%) of the records had documentation of CRC screening according to definition no. 1 and 19% according to definition no. 2. Screening rates from medical record review were lower than those derived from physician self-report. Our findings underscore the need for interventions to improve CRC screening in primary care settings.

Abstract
Colorectal cancer (CRC) is the third leading cause of cancer mortality among women. Screening can prevent the development of CRC or diagnose early disease when it can effectively be cured, however existing screening methods are underutilized. In this study, we examined the utility of an updated Health Belief Model to explain CRC screening adherence. The present study included 280 older women seeking routine mammography at a large, urban breast diagnostic facility. Overall, 50% of women were adherent to CRC screening guidelines. Multiple regression indicated that self-efficacy, physician recommendation, perceived benefits of and perceived barriers to screening accounted for 40% of variance in CRC screening adherence. However, there was no evidence for two mediational models with perceived benefits and perceived barriers as the primary mechanisms driving adherence to CRC screening. These findings may inform both future theoretical investigations as well as clinical interventions designed to increase CRC screening behavior.
