Testing behavioral economics messages to increase non-responders' participation in organized colorectal cancer-screening programs: A randomized controlled trial. Prev Med 2023; 174:107615. [PMID: 37453699 DOI: 10.1016/j.ypmed.2023.107615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 06/08/2023] [Accepted: 07/09/2023] [Indexed: 07/18/2023]
Abstract
This study aimed to evaluate the impact of behavioral economic-inspired messages on participation in colorectal cancer (CRC) screening programs. We conducted a randomized-controlled trial involving 11,505 non-responders to the CRC screening programs in Florence, Rome, and Turin in 2020. Participants aged 54-70 years were randomly assigned to four conditions. Individuals in the control conditions received a standard invitation letter while the three intervention groups included an additional paragraph featuring either i. normative feedback [F] message (giving feedback that invited subjects did not participate); ii. Minority norm [MN] message (only a minority did not participate); iii. F+ MN message (combining both messages). The primary outcome was the screening participation rate 90 days after the invitation was completed. A multivariate analysis was conducted adjusting for gender, age and birthplace. Overall, screening participation rates were 5.3% in the control condition, 7.0% in the F, 8.2% in the MN, and 7.4% in the F + MN arms (p = 0.002). Invited subjects in the MN arm were more likely to participate (adjusted Odds Ratio[aOR] = 1.38; 95% Confidence Interval [95%CI,1.13-1.68]), particularly those aged 54-59 years (aOR = 1.52; 95%CI:1.16-1.98), and 60-64 (aOR = 1.57; 95%CI:1.62-; 95%CI: 1.06-2.48). Additionally, individuals aged 60-64 invited in F and F + MN arms demonstrated a higher likelihood of participation (aOR for F arm = 1.60; 95%CI: 1.06-2.41; aOR for F + MN arm = 1.99; 95%CI: 1.35-2.92). The inclusion of MN and/or F messages in the invitation letter increased participation among previous non-responders <65 years. Behavioral economics is a promising area of interest for enhancing CRC screening participation. TRIAL REGISTRATION: ISRCTN registration number: ISRCTN11841256.

Abstract
This study aimed to determine the CRC screening coverage of people aged between 50 and 69 years who were living in Spain in 2017 and describe the factors associated with not having had a faecal occult blood test (FOBT). A cross-sectional study was performed using data from the Spanish National Health Survey 2017. We analysed 7568 individuals between the ages of 50 and 69 years. The proportion of respondents between 50 and 69 years old who had had an FOBT was 29.0% (n = 2191). The three autonomous communities with the lowest proportion of respondents who had had an FOBT were Extremadura (8.7%, n = 16), Ceuta-Melilla (10.4%, n = 3), and Andalucia (14.1%, n = 186). The variables associated with not having had an FOBT were being 50-54 years old (PR = 1.09; 95% CI 1.04-1.14), having been born outside of Spain (PR = 1.11; 95% CI 1.06-1.16), not having been vaccinated against the flu (PR = 1.09; 95% CI 1.04-1.15), never having had a colonoscopy (PR = 1.49; 95% CI 1.40-1.59), not having had an ultrasound scan in the last year (PR = 1.09; 95% CI 1.04-1.14), and not having seen a primary care physician in the last month (PR = 1.08; 95% CI 1.04-1.12). The factors associated with not getting an FOBT were young age, having been born outside of Spain, not having been vaccinated against the flu in the last campaign, and not making frequent use of healthcare services.

Abstract
BACKGROUND We sought to investigate intentions to undergo primary screening with colonoscopy in an attempt to predict future colorectal cancer screening behaviors and the feasibility of implementing colonoscopy as the primary screening modality for colorectal cancer in the National Cancer Screening Program (NCSP) of Korea. METHODS Data were obtained from a nationwide online survey conducted in 2018. The survey included a total of 800 eligible adults aged over 45 years. Study measures included the history of screening colonoscopy within the past 10 years and intentions to undergo primary screening with colonoscopy under the NCSP based on the five constructs of the Health Belief Model. Logistic regression analysis was conducted to examine factors associated with intentions to undergo primary screening with colonoscopy. RESULTS Approximately 77% of the participants expressed strong willingness to undergo primary screening with colonoscopy under the NCSP. Higher perceived severity and perceived benefits were significantly associated with stronger intentions to undergo screening with colonoscopy (adjusted odds ratio [aOR], 1.53; 95% confidence interval [CI], 1.10-2.14 and aOR, 2.74; 95% CI, 1.76-4.28, respectively). Greater perceived barriers (aOR, 0.65; 95% CI, 0.45-0.93) were significantly associated with weaker intentions. Cues to action elicited the strongest screening intentions (aOR, 8.28; 95% CI, 5.23-13.12). CONCLUSION The current study findings highlight the need for increasing awareness of the severity of CRC and the benefits of colonoscopy screening. Family-orientated recommendation strategies and reducing complications may boost an individual's intentions to undergo colonoscopy.

Abstract
AIMS Colorectal cancer (CRC) is one of the public health burdens that can be lowered by early detection. This study aims to examine the preferences and willingness-to-pay of a population at risk for CRC screening in Thailand. Understanding the preferences for these individuals at risk would help Thailand, as an example of LMICs, to design effective population-based CRC screening programs. MATERIALS AND METHODS A discrete choice experiment (DCE) was conducted among screening-naïve adults aged 50-75 years, who were at risk of CRC, in the out-patient department of a tertiary care hospital in Thailand. A DCE questionnaire was developed from six CRC screening attributes. Each questionnaire was composed of six choice sets and each contained two alternatives described by the different levels of attributes and an opt-out alternative. Participants were asked to choose one alternative from each choice set. A multinomial logit model was developed to determine the relative preference of each attribute. The willingness-to-pays for all attributes and screening modalities and the estimated preferred choices of the annual fecal immunochemical test (FIT), 10-yearly colonoscopy, 5-yearly double-contrast barium enema (DCBE), 5-yearly computed tomographic colonography (CTC), 5-yearly flexible sigmoidoscopy (FS), and no screening was calculated and compared. RESULTS Four hundred participants were included. All attributes, except pain and less bowel preparation, were statistically associated with the participants' preference (p < .05). They preferred screenings with a high-risk reduction of CRC-related mortality, no complication, 5-year interval, and lower cost. The estimated preferred choices of FIT, colonoscopy, DCBE, CTC, and FS were 38.2%, 11.4%, 14.6%, 9.2%, and 11.4%, respectively. The willingness-to-pays for each screening modality was US$251, US$189, US$183, US$154, and US$142 (8,107, 6,105, 5,911, 4,974, and 4,587 THB) per episode, respectively. CONCLUSIONS The risk reduction of CRC-related mortality, complication, screening interval, and cost influenced the CRC screening preferences of Thai adults. FIT was the most preferred. Policymakers can develop a successful CRC screening campaign using these findings, incorporating the perspective of the population at risk in policy formulation to accomplish their goals.

Abstract
Access to care varies by sex such that interactions with insurance status result in mixed patterns of preventive services utilization. We examined sex-specific effects of ACA Medicaid expansions on receipt of CRC screening. We used Behavioral Risk Factor Surveillance System data (2008-2016) for adults aged 50-64 years with household income ≤138% of federal poverty level to examine self-reported lifetime use of guideline-recommended CRC screening services overall and by screening modality. We employed difference-in-difference models comparing changes in CRC screening in 20 Medicaid expansion states before and after the ACA to changes in 18 states that did not expand Medicaid during our study period. We divided the expansion period into implementation (2014) and post-expansion (2016) periods to account for possible lagged effects. We observed time-varying effects of Medicaid expansion that revealed relative increases in CRC screening occurring during the post-expansion period. Heterogeneous effects by sex and by screening modality were also observed: there was a significant relative increase of 16.2 percentage points (95% CI [2.2, 30.2]; p-value = 0.023) in lifetime colonoscopy use among women in expansion states relative to non-expansion states in the post-expansion period. There were no significant effects of Medicaid expansion among men. Health insurance expansion had a lagged but significant effect on CRC screening among low-income non-elderly women in Medicaid expansion states, but no effect for men. The observed increase in CRC screening among women suggests that barriers to CRC screening may differ by sex, and tailored interventions to increase CRC screening improve outcomes.

Abstract
Colorectal cancer (CRC) represents a global public health concern. CRC screening is associated with significant reductions in CRC incidence and mortality, however, uptake is suboptimal. This systematic review and meta-analysis of randomised controlled trials explored the effectiveness of interventions designed to increase screening uptake, plus the impact of various moderators. Data from 102 studies including 1.94 million participants were analysed. Results showed significant benefit of all interventions combined (OR, 1.49, 95% CI: 1.43, 1.56, p < 0.001). The effects were similar in studies using objective versus self-reported uptake measures and lower in studies judged to be at high risk of bias. Moderator analyses indicated significant effects for aspects of behaviour (effects lower for studies on non-endoscopic procedures), and intervention (effects higher for studies conducted in community settings, in healthcare systems that are not free, and that use reminders, health-professional providers, paper materials supplemented with in-person or phone contact, but avoid remote contact). Interventions that included behaviour change techniques targeting social support (unspecified or practical), instructions or demonstration of the behaviour, and that added objects to the environment produced stronger effects. The way in which findings can inform interventions to improve CRC screening uptake is discussed.

Associations between area-level deprivation, rural residence, physician density, screening policy and late-stage colorectal cancer in Canada. Cancer Epidemiol 2019; 64:101654.

Abstract
BACKGROUND Important social disparities in colorectal screening exist in Canada. Few studies have assessed disparities further along the cancer control continuum. Here we assess the associations between social and material deprivation, physician density, rural residence, and the absence of provincial mail-based screening programs and colorectal cancer (CRC) stage at diagnosis. METHODS Colorectal cancer cases and stage data ("local or regional" if stage 0, I, or II, "late" if stage III or IV) were obtained through the Canadian Cancer Registry (2011-2015, N = 54,745). Cases were linked to 2006 Canadian Census Dissemination Area-level data on rural/urban status, exposure to a provincial mail-based screening program, and social and material deprivation (Pampalon Index quintile groups); and to Scott's Medical Database 2011 physician density data (<7 vs. ≥ 7/10,000). Age, sex, and predictor-adjusted Generalized estimating equation (GEE) Poisson models were used to determine independent associations between predictors and late-stage at diagnosis. RESULTS Half of CRC cases are diagnosed at stage III or IV (51 %), with younger age groups experiencing higher late-stage prevalence (57 % among those aged 18-49). The covariate-adjusted late-stage prevalence was 2-percentage points higher in most materially- and socially-deprived areas (95 % CI: 1 %, 4 %, in both, respectively) and in provinces with no mail-based screening programs (95 % CI: 1 %, 2 %). No significant differences were observed according to rural residence or physician density. CONCLUSIONS Social disparities in late-stage CRC diagnosis are modest. Continued surveillance of these disparities may be warranted as provinces continue to promote early cancer detection through screening, and stage distributions may change overtime.

Abstract
Colorectal adenomas are precursor lesions of colorectal adenocarcinoma. The transition from adenoma to carcinoma in patients with colorectal cancer (CRC) has been associated with an accumulation of genetic aberrations. However, criteria that can screen adenoma progression to adenocarcinoma are still lacking. This present study is the first attempt to identify genetic aberrations, such as the somatic mutations, copy number variations (CNVs), and high-frequency mutated genes, found in Thai patients. In this study, we identified the genomic abnormality of two sample groups. In the first group, five cases matched normal-colorectal adenoma-colorectal adenocarcinoma. In the second group, six cases matched normal-colorectal adenomas. For both groups, whole-exome sequencing was performed. We compared the genetic aberration of the two sample groups. In both normal tissues compared with colorectal adenoma and colorectal adenocarcinoma analyses, somatic mutations were observed in the tumor suppressor gene APC (Adenomatous polyposis coli) in eight out of ten patients. In the group of normal tissue comparison with colorectal adenoma tissue, somatic mutations were also detected in Catenin Beta 1 (CTNNB1), Family With Sequence Similarity 123B (FAM123B), F-Box And WD Repeat Domain Containing 7 (FBXW7), Sex-Determining Region Y-Box 9 (SOX9), Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5), Frizzled Class Receptor 10 (FZD10), and AT-Rich Interaction Domain 1A (ARID1A) genes, which are involved in the Wingless-related integration site (Wnt) signaling pathway. In the normal tissue comparison with colorectal adenocarcinoma tissue, Kirsten retrovirus-associated DNA sequences (KRAS), Tumor Protein 53 (TP53), and Ataxia-Telangiectasia Mutated (ATM) genes are found in the receptor tyrosine kinase-RAS (RTK-RAS) signaling pathway and p53 signaling pathway, respectively. These results suggest that APC and TP53 may act as a potential screening marker for colorectal adenoma and early-stage CRC. This preliminary study may help identify patients with adenoma and early-stage CRC and may aid in establishing prevention and surveillance strategies to reduce the incidence of CRC.

Abstract
Background The overall aim of this study was to describe trends in participation rates and detection of lesions in a colorectal cancer (CRC) screening programme, during three rounds, using faecal immunochemical test (FIT). Methods National registers were used to collect data on invitations for CRC screening in the Basque Country (Spain) from 2009 to 2014. Information about participation, age, gender and lesions in each round were collected. Results A total of 961.533 individuals were included in the analysis; respectively, 584.950, 298.143 and 78.440 in the first, second and third rounds. The average participation rate was 68.4% (66.8, 70.4 and 72.3%, respectively by round; P < 0.001) and the positivity rate was 6.3% (7, 5.5 and 5.4%, respectively by round; P < 0.001). The participation rate increased significantly with age and was found to be higher in women versus men. A total of 15.144 advanced adenomas and 2.131 CRCs were diagnosed, leading to a detection rate of 23.9 and 3.4‰, respectively. Regarding gender, men had the highest rates in all periods and rounds. The detection rate of advanced neoplasia was lower in the regular when compared with irregular paricipants. Conclusions In a CRC screening, this organization obtained high FIT participation rates. Older participants and women were associated with a higher participation. The detection rate of lesions was higher in men, independent on age and round.

Abstract
Background Participation in colorectal screening remains low even in countries with universal health coverage. Area-level determinants of low screening participation in Canada remain poorly understood. Methods We assessed the association between area-level income and two indicators of colorectal screening (having never been screened, having not been screened recently) by linking census-derived local area-level income data with self-reported screening data from urban-dwelling respondents to the Canadian Community Health Survey (50-75 years of age, cycles 2005 and 2007, n = 18,362) who reported no known risk factors for colorectal cancer. Generalized estimating equation Poisson models estimated the prevalence ratios and differences for having never been screened and having not been screened recently, adjusting for individual-level income, education, marital status, having a regular physician, age, and sex. Results About 53% of the study population had never been screened. Among individuals who had ever been screened, 35% had been screened recently. Adjusting for covariates, lower area-level income was associated with having never been screened [covariate-adjusted prevalence ratios: 1.24 for quartile 1; 95% confidence limits (cl): 1.16, 1.34; 1.25 for quartile 2; 95% cl: 1.15, 1.33; 1.15 for quartile 3; 95% cl: 1.08, 1.23]. Among individuals who had been screened in their lifetime, area-level income was not associated with having not been screened recently. Conclusions Lower area-level income is associated with having never been screened for colorectal cancer even after adjusting for individual socioeconomic factors. Those findings highlight the potential importance of socioeconomic contexts for colorectal screening initiation and merit attention in both future research and surveillance efforts.

Abstract
BACKGROUND Colorectal cancer screening participation is lower among recent immigrants than among Canadian-born individuals. We assessed whether this screening disparity is mediated by access to regular primary care physicians (PCP). METHODS Pooling years 2003 to 2014 of the Canadian Community Health Survey, lifetime screening in respondents aged 50 to 75 years of age who immigrated in the previous 10 years (n = 1,067) was compared with Canadian-born respondents (N = 102,366). Regression- and inverse probability weighting-based methods were used to estimate the total effect (TE) and controlled direct effect (CDE) of recent immigration on never having received either a stool- or endoscopic-based screening test. The proportion of the TE that would be eliminated if all had a PCP was computed using these estimates [proportion eliminated (PE) = (TE - CDE)/(TE - 1)]. Analyses were stratified by visible minority status and adjusted for income, rurality, age, sex, marital status, education, and exposure to a provincially organized colorectal screening program. RESULTS The prevalence of never having been screened was 71% and 57% in visible minority and white recent immigrants, respectively, and 46% in white Canadian-born respondents. If all had regular PCPs, there would be no reduction in the screening inequality between white recent immigrants and Canadian-born (null PE), and the inequality between visible minority immigrants and white Canadian-born may increase by 6% to 13%. CONCLUSIONS Ensuring all have regular PCPs may lead to greater screening gains among Canadian-born than recent immigrants. IMPACT Improving access to PCPs may increase colorectal screening overall, but not reduce immigration-based disparities screening. Alternative interventions to reduce this disparity should be explored.

Abstract
Background Colorectal cancer (CRC) screening is an important modifiable behaviour for cancer control. Regular screening, following recommendations for the type, timing and frequency based on personal CRC risk, contributes to earlier detection and increases likelihood of successful treatment. Methods To determine adherence to screening recommendations in a large provincial cohort of adults, participants in Alberta’s Tomorrow Project (n = 9641) were stratified based on increasing level of CRC risk: age (Age-only), family history of CRC (FamilyHx), personal history of bowel conditions (PersonalHx), or both (Family/PersonalHx) using self-reported information from questionnaires. Provincial and national guidelines for timing and frequency of screening tests were used to determine if participants were up-to-date based on their CRC risk. Screening status was compared between enrollment (2000–2006) and follow-up (2008) to determine screening pattern over time. Results The majority of participants (77%) fell into the average risk Age-only strata. Only a third of this strata were up-to-date for screening at baseline, but the proportion increased across the higher risk strata, with > 90% of the highest risk Family/PersonalHx strata up-to-date at baseline. There was also a lower proportion (< 25%) of the Age-only group who were regular screeners over time compared to the higher risk strata, though age, higher income and uptake of other screening tests (e.g. mammography) were associated with a greater likelihood of regular screening in multinomial logistic regression. Conclusions The low (< 50%) adherence to regular CRC screening in average and moderate risk strata highlights the need to further explore barriers to uptake of screening across different risk profiles.

Abstract
Introduction: This study aimed to investigate the factors associated with FOBT screening for colorectal cancer based on the components of Health Belief Model and social support in Fasa City, Fars Province, Iran. Materials and Methods: This was a cross-sectional study carried out on 240 subjects in people of Fasa city who had 50 years old and above. The subjects in this study were assigned to two groups of 120 patients. The first group included people over 50 years, who referred to the diagnostic laboratories for doing FOBT, but the second group included people aged 50 years and above who did not refer to a laboratory for doing FOBT and were assessed by questionnaires at home. Data were collected through a questionnaire based on health belief model and perceived social support. Results: The referring group included 61.3 percent women and 38.7 percent men, with a mean age of 65.24 ± 8.01. The non-referring group included 59.7 percent women and 40.3 percent men, with a mean age of 64.21 ±7.53 (p=0.24). In the referring group, 64.2 percent had undergone FOBT in the past year, while in the non-referring group only 12.72percent had done so (p=0.001). The results showed that the referring group obtained higher scores on awareness about CRC and ways to prevent it, and on HBM Model constructs, and social support compared to the non-referring group (p<0.001). In addition, the referring group reported significantly lower Perceived Barriers compared to the non-referring group (p<0.001). Conclusion: The results showed significant differences between the two groups in terms of HBM components and perceived social support for doing FOBT. Therefore, theory-based educational interventions can be used to increase individuals’ Perceived Severity, Perceived Susceptibility, and Perceived Benefits and reduce their Perceived Barriers in order to empower and encourage people to perform FOBT.

Abstract
Abstract The population-based Basque Colorectal Cancer (CRC) Screening Programme started in 2009 with a biennial immunochemical quantitative test (FIT) biennial and colonoscopy under sedation in positive cases. The population target of 586,700 residents was from 50 to 69 years old and the total coverage was reached at the beginning of 2014. The aim of our study was to determine possible scenarios in terms of incidence, mortality and reduction of Life-years-Lost (L-y-L) in the medium and long term of CRC. Methods Invitations were sent out by the Programme from 2009 to 2014, with combined organizational strategies. Simulation was done by MISCAN-colon (Microsimulation Screening Analysis) over 30 years comparing the results of screening vs no-screening, taking the population-based Cancer Registry into account. Lifetime population and real data from the Programme were used from 2008 to 2012. The model was run differentially for men and women. Results 924,416 invitations were sent out from 2009 to 2014. The average participation rate was 68.4%, CRC detection rate was 3.4% and the Advanced Adenoma detection rate was 24.0‰, with differences observed in sex and age. Future scenarios showed a higher decrease of incidence (17.2% vs 14.7%), mortality (28.1% vs 22.4%) and L-y-L (22.6% vs 18.4%) in men than women in 2030. Conclusions The Basque Country CRC Programme results are aligned to its strategy and comparable to other programmes. MISCAN model was found to be a useful tool to predict the benefits of the programme in the future. The effectiveness of the Programme has not been formally established as case control studies are required to determine long term benefits from the screening strategy.

Abstract
OBJECTIVE The global burden of colorectal cancer (CRC) is expected to increase by 60% to more than 2.2 million new cases and 1.1 million deaths by 2030. In this study, we aim to describe the recent CRC incidence and mortality patterns and trends linking the findings to the prospects of reducing the burden through cancer prevention and care. DESIGN Estimates of sex-specific CRC incidence and mortality rates in 2012 were extracted from the GLOBOCAN database. Temporal patterns were assessed for 37 countries using data from Cancer Incidence in Five Continents (CI5) volumes I-X and the WHO mortality database. Trends were assessed via the annual percentage change using joinpoint regression and discussed in relation to human development levels. RESULTS CRC incidence and mortality rates vary up to 10-fold worldwide, with distinct gradients across human development levels, pointing towards widening disparities and an increasing burden in countries in transition. Generally, CRC incidence and mortality rates are still rising rapidly in many low-income and middle-income countries; stabilising or decreasing trends tend to be seen in highly developed countries where rates remain among the highest in the world. CONCLUSIONS Patterns and trends in CRC incidence and mortality correlate with present human development levels and their incremental changes might reflect the adoption of more western lifestyles. Targeted resource-dependent interventions, including primary prevention in low-income, supplemented with early detection in high-income settings, are needed to reduce the number of patients with CRC in future decades.

Abstract
OBJECTIVE To determine the association between vasectomy and prostate cancer, adjusting for measures of health seeking behaviour. DESIGN Population based matched cohort study. SETTING Multiple validated healthcare databases in Ontario, Canada, 1994-2012. PARTICIPANTS 326 607 men aged 20 to 65 who had undergone vasectomy were identified through physician billing codes and matched 1:1 on age (within two years), year of cohort entry, comorbidity score, and geographical region to men who did not undergo a vasectomy. MAIN OUTCOMES MEASURES The primary outcome was incident prostate cancer. Secondary outcomes were prostate cancer related grade, stage, and mortality. RESULTS 3462 incident cases of prostate cancer were identified after a median follow-up of 10.9 years: 1843 (53.2%) in the vasectomy group and 1619 (46.8%) in the non-vasectomy group. In unadjusted analysis, vasectomy was associated with a slightly increased risk of incident prostate cancer (hazard ratio 1.13, 95% confidence interval 1.05 to 1.20). After adjustment for measures of health seeking behaviour, however, no association remained (adjusted hazard ratio 1.02, 95% confidence interval 0.95 to 1.09). Moreover, no association was found between vasectomy and high grade prostate cancer (adjusted odds ratio 1.05, 95% confidence interval 0.67 to 1.66), advanced stage prostate cancer (adjusted odds ratio 1.04, 0.81 to 1.34), or mortality (adjusted hazard ratio 1.06, 0.60 to 1.85). CONCLUSION The findings do not support an independent association between vasectomy and prostate cancer.

This paper describes how the RESPECT approach to health education guided the conceptualization and implementation of physician-directed academic detailing (AD) to increase practice-wide CRC screening uptake. METHODS Physician-directed AD was one intervention component in a large educational randomized controlled trial to increase CRC screening uptake. Study participants, primarily urban minority, were aged 50 or older, insured for CRC screening with no out-of-pocket expense and out of compliance with current screening recommendations. The trial was conducted in the New York City metropolitan area. Participants identified their primary care physician; 564 individuals were recruited, representing 459 physician practices. Two-thirds of the physician practices were randomized to receive AD. The RESPECT approach, modified for AD, comprises: 1) Rapport, 2) Educate, but don't overwhelm, 3) Start with physicians where they are, 4) Philosophical orientation based on a humanistic approach to education, 5) Engagement of the physician and his/her office staff, 6) Care and show empathy, and 7) Trust. Feasibility was assessed as rate of AD delivery. RESULTS The AD was delivered to 283 (92.5%) of the 306 practices assigned to receive it; 222/283 (78.4%) delivered to the doctor. CONCLUSION The AD was feasible and acceptable to implement across a range of clinical settings. The RESPECT approach offers a framework for tailoring educational efforts, allowing flexibility, as opposed to strict adherence to a highly structured script or a universal approach.

Abstract
OBJECTIVE The current study aimed to identify the barriers to participation among high-risk individuals in the UK Lung Cancer Screening (UKLS) pilot trial. SETTING The UKLS pilot trial is a randomised controlled trial of low-dose CT (LDCT) screening that has recruited high-risk people using a population approach in the Cambridge and Liverpool areas. PARTICIPANTS High-risk individuals aged 50-75 years were invited to participate in UKLS. Individuals were excluded if a LDCT scan was performed within the last year, if they were unable to provide consent, or if LDCT screening was unable to be carried out due to coexisting comorbidities. OUTCOME MEASURES Statistical associations between individual characteristics and UKLS uptake were examined using multivariable regression modelling. In those who completed a non-participation questionnaire (NPQ), thematic analysis of free-text data was undertaken to identify reasons for not taking part, with subsequent exploratory linkage of key themes to risk factors for non-uptake. RESULTS Comparative data were available from 4061 high-risk individuals who consented to participate in the trial and 2756 who declined participation. Of those declining participation, 748 (27.1%) completed a NPQ. Factors associated with non-uptake included: female gender (OR=0.64, p<0.001), older age (OR=0.73, p<0.001), current smoking (OR=0.70, p<0.001), lower socioeconomic group (OR=0.56, p<0.001) and higher affective risk perception (OR=0.52, p<0.001). Among non-participants who provided a reason, two main themes emerged reflecting practical and emotional barriers. Smokers were more likely to report emotional barriers to participation. CONCLUSIONS A profile of risk factors for non-participation in lung screening has emerged, with underlying reasons largely relating to practical and emotional barriers. Strategies for engaging high-risk, hard-to-reach groups are critical for the equitable uptake of a potential future lung cancer screening programme. TRIAL REGISTRATION NUMBER The UKLS trial was registered with the International Standard Randomised Controlled Trial Register under the reference 78513845.

Abstract
Background: Mortality from colorectal cancer (CRC) can be reduced drastically by early detection and early treatment. However, uptake of CRC screening is relatively low, about 50% for those whom the test is highly recommended. Objectives: We examined the influence of and racial differences in depression, insomnia, alcohol use, and tobacco use on CRC screening uptake in the US. Patients and Methods: Analysis of the 2012 National Health Information Survey data was conducted. Both weighted univariate and multiple logistic regression analyses were performed in SAS to estimate the odds ratios (ORs) and their 95% confidence intervals (CIs). A total of 21511 participants were included in the analysis. Results: Prevalence of CRC screening in the participants was 19%. Adjusting for all factors, insomnia (OR = 1.18, 95%CI = 1.06 - 1.32), moderate alcohol drinking (OR = 1.16, 95%CI = 1.01 - 1.30), past smoking (OR = 1.17, 95%CI = 1.04 - 1.32), depression (OR = 1.37, 95%CI = 1.18 - 1.58), African American (AA) race, and cancer history were positively associated with CRC screening. Females and Single were inversely associated with CRC screening prevalence. In stratified analysis by races (White and AA), depression was associated with CRC screening in both races. Marital status, smoking, cancer history and insomnia were associated with CRC screening in Whites only; while alcohol use was associated with CRC screening in AAs only. Conclusions: We have found significant associations between lifestyle factors (alcohol consumption and smoking) and mental health problems (depression and insomnia) and CRC screening uptake. To improve overall CRC screening uptake in the US, it is important to consider racial differences in predictors and tailor appropriate interventions to each racial/ethnic group.

Abstract
Colorectal cancer (CRC) is one of the leading cancers and cause of cancer deaths in American women and men. Females and males share a similar lifetime cumulative risk of CRC however, substantial differences in risk factors, tumor biology, and effectiveness of cancer prevention services have been observed between them. This review distills the evidence documenting the unique variation observed between the genders relating to CRC risk factors, screening and prevention. Consistent evidence throughout the world demonstrates that women reach equivalent levels of adenomas and CRC as men but it occurs nearly a decade later in life than in their male counterparts. Women have a higher proportion of tumors which are hypermethylated, have microsatellite instability and located in the proximal colon suggesting the serrated pathway may be of greater consequence in them than in men. Other CRC risk factors such as smoking, diet and obesity have been shown to have disparate effects on women which may related to interactions between estrogen exposure, body fat distribution, and the biologic underpinnings of their tumors. There is data showing the uptake, choice, and efficacy of different CRC screening methods in women is dissimilar to that in men. The mortality benefit from FOBT, sigmoidoscopy, and protection from interval CRC by colonoscopy appears to be lower in women than men. A greater understanding of these gender idiosyncrasies will facilitate an personalized approach to CRC prevention and should ultimately lead to a reduced burden of disease.

Abstract
PURPOSE There is limited evidence for the effectiveness of pay for performance despite its widespread use. We assessed whether the introduction of a pay-for-performance scheme for primary care physicians in Ontario, Canada, was associated with increased cancer screening rates and determined the amounts paid to physicians as part of the program. METHODS We performed a longitudinal analysis using administrative data to determine cancer screening rates and incentive costs in each fiscal year from 1999/2000 to 2009/2010. We used a segmented linear regression analysis to assess whether there was a step change or change in screening rate trends after incentives were introduced in 2006/2007. We included all Ontarians eligible for cervical, breast, and colorectal cancer screening. RESULTS We found no significant step change in the screening rate for any of the 3 cancers the year after incentives were introduced. Colon cancer screening was increasing at a rate of 3.0% (95% CI, 2.3% to 3.7%) per year before the incentives were introduced and 4.7% (95% CI, 3.7% to 5.7%) per year after. The cervical and breast cancer screening rates did not change significantly from year to year before or after the incentives were introduced. Between 2006/2007 and 2009/2010, $28.3 million, $31.3 million, and $50.0 million were spent on financial incentives for cervical, breast, and colorectal cancer screening, respectively. CONCLUSIONS The pay-for-performance scheme was associated with little or no improvement in screening rates despite substantial expenditure. Policy makers should consider other strategies for improving rates of cancer screening.

Abstract
BACKGROUND Colorectal cancer is an important public health problem in Spain. Over the last decade, several regions have carried out screening programmes, but population participation rates remain below recommended European goals. Reminders on electronic medical records have been identified as a low-cost and high-reach strategy to increase participation. Further knowledge is needed about their effect in a population-based screening programme. The main aim of this study is to evaluate the effectiveness of an electronic reminder to promote the participation in a population-based colorectal cancer screening programme. Secondary aims are to learn population's reasons for refusing to take part in the screening programme and to find out the health professionals' opinion about the official programme implementation and on the new computerised tool. METHODS/DESIGN This is a parallel randomised trial with a cross-sectional second stage. PARTICIPANTS all the invited subjects to participate in the public colorectal cancer screening programme that includes men and women aged between 50-69, allocated to the eleven primary care centres of the study and all their health professionals. The randomisation unit will be the primary care physician. The intervention will consist of activating an electronic reminder, in the patient's electronic medical record, in order to promote colorectal cancer screening, during a synchronous medical appointment, throughout the year that the intervention takes place. A comparison of the screening rates will then take place, using the faecal occult blood test of the patients from the control and the intervention groups. We will also take a questionnaire to know the opinions of the health professionals. The main outcome is the screening status at the end of the study. Data will be analysed with an intention-to-treat approach. DISCUSSION We expect that the introduction of specific reminders in electronic medical records, as a tool to facilitate and encourage direct referral by physicians and nurse practitioners to perform colorectal cancer screening will mean an increase in participation of the target population. The introduction of this new software tool will have good acceptance and increase compliance with recommendations from health professionals.

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.

Gender differences in attitudes impeding colorectal cancer screening. BMC Public Health 2013; 13:500.

Abstract
Background Colorectal cancer screening (CRCS) is the only type of cancer screening where both genders reduce risks by similar proportions with identical procedures. It is an important context for examining gender differences in disease-prevention, as CRCS significantly reduces mortality via early detection and prevention. In efforts to increase screening adherence, there is increasing acknowledgment that obstructive attitudes prevent CRCS uptake. Precise identification of the gender differences in obstructive attitudes is necessary to improve uptake promotion. This study randomly sampled unscreened, screening - eligible individuals in Ontario, employing semi-structured interviews to elicit key differences in attitudinal obstructions towards colorectal cancer screening with the aim of deriving informative differences useful in planning promotions of screening uptake. Methods N = 81 participants (49 females, 32 males), 50 years and above, with no prior CRCS, were contacted via random-digit telephone dialing, and consented via phone-mail contact. Altogether, N = 4,459 calls were made to yield N = 85 participants (1.9% response rate) of which N = 4 participants did not complete interviews. All subjects were eligible for free-of-charge CRCS in Ontario, and each was classified, via standard interview by CRCS screening decision-stage. Telephone-based, semi-structured interviews (SSIs) were employed to investigate gender differences in CRCS attitudes, using questions focused on 5 attitudinal domains: 1) Screening experience at the time of interview; 2) Barriers to adherence; 3) Predictors of Adherence; 4) Pain-anxiety experiences related to CRCS; 5) Gender-specific experiences re: CRCS, addressing all three modalities accessible through Ontario’s program: a) fecal occult blood testing; b) flexible sigmoidoscopy; c) colonoscopy. Results Interview transcript analyses indicated divergent themes related to CRCS for each gender: 1) bodily intrusion, 2) perforation anxiety, and 3) embarrassment for females and; 1) avoidant procrastination with underlying fatalism, 2) unnecessary health care and 3) uncomfortable vulnerability for males. Respondents adopted similar attitudes towards fecal occult blood testing, flexible sigmoidoscopy and colonoscopy, and were comparable in decision stage across tests. Gender differences were neither closely tied to screening stage nor modality. Women had more consistent physician relationships, were more screening-knowledgeable and better able to articulate views on screening. Men reported less consistent physician relationships, were less knowledgeable and kept decision-making processes vague and emotionally distanced (i.e. at ‘arm’s length’). Conclusions Marked differences were observed in obstructive CRCS attitudes per gender. Females articulated reservations about CRCS-associated distress and males suppressed negative views while ambiguously procrastinating about the task of completing screening. Future interventions could seek to reduce CRCS-related stress (females) and address the need to overcome procrastination (males).

Abstract
BACKGROUND Despite evidence of the effectiveness of cancer preventive services and the increasing development of guidelines, actual rates of delivery of cancer prevention activities remain low. Due to their frequent front-line contact with the public, family physicians (GPs) have the potential to play an important role in the primary prevention of cancer. However, there is a lack of information about their actual role in cancer prevention. The aim of this study was to investigate the actual and potential roles of general practitioners (GP) in the prevention of cancer. METHODS A sequential exploratory mixed methods approach was used. The sample included all the General Practice (GP) practices in a region in the UK (n=345). Postal questionnaires were administered to GPs (n=1249); following 290 returns (response rate 23%), semi-structured interviews were undertaken with GPs (n=14). RESULTS The majority of the GP respondents (66.4%, n=184) considered that they routinely provided cancer prevention information. This was specifically focusing on smoking cessation as almost all GPs (96.8%, n=270) enquired about a patient's smoking status. Overall, 47.2% (n=128) of GP respondents indicated that they felt they did not have time to perform a cancer prevention role; however, 88.3% (n=242) still felt that they had the 'opportunity' to do so. Over half the sample (61.3%, n=168) indicated that imposed health priorities and targets militated against providing cancer prevention activities. Almost all the GP respondents (98.9%, n=273) agreed with empowering individuals to take responsibility for their health issues. The GPs identified the need for alternative models for cancer prevention beyond current face to face patient care, including other health and non-health professionals. Whilst lack of time was identified as a critical factor, the GPs indicated that significant efforts were made to encourage patients to take personal responsibility for lifestyle choices. CONCLUSIONS The GPs indicated a need for training around behavioural change and theories of motivation and action. This has implications for primary care and family physicians worldwide. While doctor-patient consultations and the physicians' credibility offer great potential for cancer prevention, time pressures and imposed government targets often mean that their actual cancer prevention role is reduced.

Abstract
In Malaysia, colorectal cancer is the most common cancer in males and the third most common in females. Mortality due to colorectal cancer can be effectively reduced with early diagnosis. This study was designed to look into colorectal cancer screening participation and its barriers among average risk individuals in Malaysia. A cross sectional study was conducted from August 2009 till April 2010 involving average risk individuals from 44 primary care clinics in West Malaysia. Each individual was asked whether they have performed any of the colorectal cancer screening methods in the past five years. The barrier questions had three domains: patient factors, test factors and health care provider factors. Descriptive analysis was achieved using Statistical Program for Social Sciences (SPSS) version 12.0. A total of 1,905 average risk individuals responded making a response rate of 93.8%. Only 13 (0.7%) respondents had undergone any of the colorectal cancer screening methods in the past five years. The main patient and test factors for not participating were embarrassment (35.2%) and feeling uncomfortable (30.0%), respectively. There were 11.2% of respondents who never received any advice to do screening. The main reason for them to undergo screening was being advised by health care providers (84.6%). The study showed that participation in colorectal cancer screening in Malaysia is extremely low and multiple factors contribute to this situation. Given the importance of the disease, efforts should be made to increase colorectal cancer screening activities in Malaysia.

Abstract
BACKGROUND AND AIMS In France, participation in organized colorectal cancer screening remains low. The objective of this study was to identify the determinants of participation in colorectal cancer screening in Isère, a French administrative entity. METHODS This study examined the target population invited for screening between 2007 and 2008 in Isère. The statistical analysis method was based on a two-level logistic regression model: the first was the individual level relative to the individuals invited for screening and the second was an aggregate level corresponding to the socioeconomic level of an invited person's residence area (IRIS: "Ilot regroupé pour l'Information Statistique"; Regrouped statistical information block). The evaluation of the socioeconomic level was based on the Townsend deprivation. RESULTS Participation varied depending on sex, age, and health insurance plan. The people residing in the least deprived IRISes participated more than individuals residing in the most deprived IRISes. The multilevel analysis showed a 24% difference in participation between the least and the most deprived IRISes. CONCLUSIONS The use of socioeconomic data on the IRIS geographical unit has identified, socially and geographically, the populations that participate the least, although this reflects "mean" behaviors. These results could be used to set up targeted actions to encourage participation in these populations.

Abstract
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. Many, if not most, cases arise from premalignant lesions (adenomas) which may be identified and removed prior to becoming frankly malignant. For over a decade, colonoscopy has been the preferred modality for both CRC screening and prevention in the US. Early reports suggested that colonoscopic screening imparted a 90% risk reduction for colorectal cancer. Subsequent studies showed that estimate to be overly optimistic. While still an outstanding CRC screening and detection tool, colonoscopy has several important limitations. Some of these limitations relate to the mechanics of the procedure such as the risk of colonic perforation, bleeding, adverse consequences of sedation, and the inability to detect all colonic polyps. Other limitations reflect issues with patient perception regarding colonoscopy which, at least in part, drive patient non-adherence to recommended testing. This review examines the literature to address several important issues. First, we analyze the effect of colonoscopy on CRC incidence and mortality. Second, we consider the patient-based, periprocedural, and intraprocedural factors which may limit colonoscopy as a screening modality. Third, we explore new techniques and technologies which may enhance the efficacy of colonoscopy for adenoma detection. Finally, we discuss the short and long-term future of colonoscopy for CRC screening and the factors which may affect this future.

Abstract
BACKGROUND Despite the positive conclusions of several randomized controlled trials and the publication of national recommendations on colorectal cancer (crc) screening, uptake remained low. The inauguration of the National Colorectal Cancer Screening Network in 2007, the same year that the first screening program was announced in Canada, provided an opportunity for integrated knowledge translation to accelerate the processes of program implementation and screening uptake. AIM Two primary aims were identified. The first focused on means to monitor the effects of various implementation plans in delivering high-quality population-based crc screening. The second focused on identifying and addressing knowledge gaps that may impair screening participation. METHOD The methods used are described in the context of the knowledge-to-action cycle and demonstrate that the initiative itself dictates the point in the cycle at which to start. RESULTS The identified need to monitor various implementation plans resulted in the shared development of a quality determinants document. All programs committed to designing data collection so that core components could be measured and compared; 6 operating programs have conducted the first data collection, which will allow for monitoring and for new knowledge creation as the process develops further. The knowledge gap identification project started with new knowledge creation, which identified a higher-than-expected willingness of Canadians to discuss crc screening with physicians, but a low level of understanding of screening as a wellness-related behaviour. Knowledge translation interventions have been developed with the stakeholders to address those gaps, and ongoing surveys to be carried out later in 2011 will help to gauge progress in the understanding and acceptance of crc screening by the population. CONCLUSIONS A national network that engaged all programs, policymakers, experts, and lay representatives successfully used knowledge translation principles to enhance the trajectory of crc screening in Canada.

Abstract
BACKGROUND Colorectal cancer (CRC) is the third most common cancer in Canada. Screening guidelines recommend that first-time screening should occur at 50 years of age for average-risk individuals and at 40 years of age for those with a family history of CRC. OBJECTIVE To examine whether persons with a positive CRC family history were achieving screening at 40 years of age and whether average-risk persons were achieving screening at 50 years of age. METHODS The present study was a cross-sectional analysis of subjects who entered a colon cancer screening program and were undergoing CRC screening for the first time. RESULTS A total of 778 individuals were enrolled in the present study: 340 (174 males) with no family history of CRC, and 438 (189 males) with a positive family history of CRC. For the group with a positive family history, the mean (± SD) age for primary screening was 54.4 ± 8.5 years, compared with 58.2 ± 6.4 years for the group with no family history. On average, those with a positive family history initiated screening 3.8 years (95% CI 2.8 to 4.8; P<0.05) earlier than those without. Adenoma polyp detection rate for the positive family history group was 20.8% (n=91) compared with 23.5 % (n=80) for the group with no family history. CONCLUSIONS Individuals with a positive CRC family history are initiating screening approximately four years earlier than those without a family history; nevertheless, both groups are undergoing screening well past current guideline recommendations.

Abstract
OBJECTIVES To identify barriers to and facilitators of colorectal cancer (CRC) screening participation among different cultural subgroups in South Australia, and to describe how these might be shared or be distinct across these groups. DESIGN, PARTICIPANTS AND SETTING Qualitative study using individual interviews in Adelaide, South Australia, between July 2009 and December 2010. Participants were recruited from five culturally distinct groups in SA (Greek, Vietnamese, Iranian, Indigenous and Anglo-Australian) and included people who had participated in CRC screening and people who had not. MAIN OUTCOME MEASURES Factors that may act as barriers to or enablers of CRC screening. RESULTS We interviewed 121 people. Members of all groups expressed positive attitudes towards cancer screening. However, we also noted a lack of knowledge about bowel cancer and its screening tests across all groups, and that the tests were viewed as unpleasant. Issues that differed across groups included language barriers, fatalistic views about cancer, embarrassment, the importance of privacy, the significance of a doctor's recommendation, moral obligations, and culture-specific concerns. CONCLUSIONS This study suggests that population-based screening programs may need to be modified to facilitate access and participation among minority populations and Indigenous people if equity in screening is to be achieved.

Abstract
BACKGROUND Fertility is a priority for many young women with breast cancer. Women need to be informed about interventions to retain fertility before chemotherapy so as to make good quality decisions. This study aimed to prospectively evaluate the efficacy of a fertility-related decision aid (DA). METHODS A total of 120 newly diagnosed early-stage breast cancer patients from 19 Australian oncology clinics, aged 18-40 years and desired future fertility, were assessed on decisional conflict, knowledge, decision regret, and satisfaction about fertility-related treatment decisions. These were measured at baseline, 1 and 12 months, and were examined using linear mixed effects models. RESULTS Compared with usual care, women who received the DA had reduced decisional conflict (β=-1.51; 95%CI: -2.54 to 0.48; P=0.004) and improved knowledge (β=0.09; 95%CI: 0.01-0.16; P=0.02), after adjusting for education, desire for children and baseline uncertainty. The DA was associated with reduced decisional regret at 1 year (β=-3.73; 95%CI: -7.12 to -0.35; P=0.031), after adjusting for education. Women who received the DA were more satisfied with the information received on the impact of cancer treatment on fertility (P<0.001), fertility options (P=0.005), and rated it more helpful (P=0.002), than those who received standard care. CONCLUSION These findings support widespread use of this DA shortly after diagnosis (before chemotherapy) among younger breast cancer patients who have not completed their families.

Abstract
BACKGROUND Several jurisdictions attempting to reform primary care have focused on changes in physician remuneration. The goals of this study were to compare the delivery of preventive services by practices in four primary care funding models and to identify organizational factors associated with superior preventive care. METHODS In a cross-sectional study, we included 137 primary care practices in the province of Ontario (35 fee-for-service practices, 35 with salaried physicians [community health centres], 35 practices in the new capitation model [family health networks] and 32 practices in the established capitation model [health services organizations]). We surveyed 288 family physicians. We reviewed 4108 randomly selected patient charts and assigned prevention scores based on the proportion of eligible preventive manoeuvres delivered for each patient. RESULTS A total of 3284 patients were eligible for at least one of six preventive manoeuvres. After adjusting for patient profile and contextual factors, we found that, compared with prevention scores in practices in the new capitation model, scores were significantly lower in fee-for-service practices (β estimate for effect on prevention score = -6.3, 95% confidence interval [CI] -11.9 to -0.6) and practices in the established capitation model (β = -9.1, 95% CI -14.9 to -3.3) but not for those with salaried remuneration (β = -0.8, 95% CI -6.5 to 4.8). After accounting for physician characteristics and organizational structure, the type of funding model was no longer a statistically significant factor. Compared with reference practices, those with at least one female family physician (β = 8.0, 95% CI 4.2 to 11.8), a panel size of fewer than 1600 patients per full-time equivalent family physician (β = 6.8, 95% CI 3.1 to 10.6) and an electronic reminder system (β = 4.6, 95% CI 0.4 to 8.7) had superior prevention scores. The effect of these three factors was largely but not always consistent across the funding models; it was largely consistent across the preventive manoeuvres. INTERPRETATION No funding model was clearly associated with superior preventive care. Factors related to physician characteristics and practice structure were stronger predictors of performance. Practices with one or more female physicians, a smaller patient load and an electronic reminder system had superior prevention scores. Our findings raise questions about reform initiatives aimed at increasing patient numbers, but they support the adoption of information technology.

Abstract
AIMS To describe and compare attendance rates and the proportions of people identified with Type 2 diabetes mellitus in people with previously unknown diabetes who participated in screening programmes undertaken in general practice in the UK, Denmark and the Netherlands as part of the ADDITION-Europe study. METHODS In Cambridge, routine computer data searches were conducted to identify individuals aged 40-69 years at high risk of Type 2 diabetes using the Cambridge Diabetes Risk Score. In Denmark, the Danish Diabetes Risk Score was mailed to individuals aged 40-69 years, or completed by patients visiting their general practitice. In the Netherlands, the Hoorn Symptom Risk Questionnaire was mailed to individuals aged 50-69 years. In these three centres, high-risk individuals were invited to attend subsequent steps in the screening programme, including random blood glucose, HbA(1c) , fasting blood glucose and/or oral glucose tolerance test. In Leicester, eligible people aged 40-69 years were invited directly for an oral glucose tolerance test. In all centres, Type 2 diabetes was defined according to World Health Organization 1999 diagnostic criteria. RESULTS Attendance rates ranged from 20.2% (oral glucose tolerance test in Leicester without pre-stratification) to 95.1% (random blood glucose in opportunistic screening in Denmark in high-risk people). The percentage of people with newly detected Type 2 diabetes from the target population ranged from 0.33% (Leicester) to 1.09% (the Netherlands). CONCLUSIONS Screening for Type 2 diabetes was acceptable and feasible, but relatively few participants were diagnosed in all participating centres. Different strategies may be required to increase initial attendance and ensure completion of screening programmes.

Abstract
BACKGROUND Our aims were to determine clinical factors associated with colorectal cancer (CRC) screening and to evaluate the relative role of patient contact with physicians and the quality of these patient-physician interactions in affecting screening. METHODS Screening-eligible patients were identified from the Health Information National Trends Survey. Determinants of CRC screening were assessed with logistic regression, and a joint effects model that considered the frequency and quality of contact with physicians was developed to explore their influence on screening. RESULTS There were 4,615 respondents of whom only 66% reported receiving CRC screening. Older age, personal history of non-CRC, family history of any cancer, high-income earners, individuals who visited their physicians ≥5 times per year, and those who rated the interactions with their physicians highly were more likely to be screened (all p < 0.05). The joint effects model revealed that quality rather than frequency of physician contact was a stronger predictor of CRC screening, but the odds of screening was highest for those who experienced both frequent and high-quality interactions with their physicians. CONCLUSIONS Contact with physicians and the quality of this interaction are associated with screening behavior. Interventions to improve these provider-related factors may promote CRC screening.

Abstract
Background It is unclear if all persons in Ontario have equal access to colonoscopy. This research was designed to describe long-term trends in the use of colonoscopy by primary care physicians (PCPs) in Ontario, and to determine whether PCP characteristics influence the use of colonoscopy. Methods We conducted a population-based retrospective study of PCPs in Ontario between the years 1996-2005. Using administrative data we identified a screen-eligible group of patients aged 50-74 years in Ontario. These patients were linked to the PCP who provided the most continuous care to them during each year. We determined the use of any colonoscopy among these patients. We calculated the rate of colonoscopy for each PCP as the number of patients undergoing colonoscopies per 100 screen eligible patients. Negative binomial regression was used to identify factors associated with the rate of colonoscopy, using generalized estimating equations to account for clustering of patients within PCPs. Results Between 7,955 and 8,419 PCPs in Ontario per year (median age 43 years) had at least 10 eligible patients in their practices. The use of colonoscopy by PCPs increased sharply in Ontario during the study period, from a median rate of 1.51 [inter quartile range (IQR) 0.57-2.62] per 100 screen eligible patients in 1996 to 4.71 (IQR 2.70-7.53) in 2005. There was substantial variation between PCPs in their use of colonoscopy. PCPs who were Canadian medical graduates and with more years of experience were more likely to use colonoscopy after adjusting for their patient characteristics. PCPs were more likely to use colonoscopy if their patient populations were predominantly women, older, had more illnesses, and if their patients resided in less marginalized neighborhoods (lower unemployment, fewer immigrants, higher income, higher education, and higher English/French fluency). Conclusions There is substantial variation in the use of colonoscopy by PCPs, and this variation has increased as the overall use of colonoscopy increased over time. PCPs whose patients were more marginalized were less likely to use colonoscopy, suggesting that there are inequities in access.

Abstract
BACKGROUND Increasing demand combined with limited capacity has resulted in long wait times for average-risk adults referred for screening colonoscopy for colorectal cancer. Management of patients on these growing wait lists is an emerging clinical issue. OBJECTIVE To inform the content and design of a mailed targeted invitation for patients to undergo annual fecal occult blood testing (FOBT) while awaiting colonoscopy. METHODS Focus groups (FGs) with average-risk patients on a wait list for screening colonoscopy at a high-throughput academic outpatient colonoscopy facility were conducted. During each FG session, feedback regarding a range of materials under consideration for the planned intervention was elicited using a semistructured facilitator guide. The FG sessions were recorded and transcribed verbatim, and analyzed using the constant comparative method to identify key themes. RESULTS Findings from the three FGs (n=28) suggested that average risk patients on a wait list for screening colonoscopy would be receptive to a targeted intervention recommending they undergo FOBT while waiting. Participants indicated that the invitation to undergo FOBT was an important acknowledgement that they were on an actively managed list, and that a mechanism to ensure that they were correctly triaged while waiting was in place. Several specific suggestions to improve the design of the targeted intervention were obtained. CONCLUSIONS Results of the present study provide useful information for developing effective strategies to manage average-risk individuals facing long wait times for screening colonoscopy.

Abstract
BACKGROUND When performed competently, colonoscopy screening can reduce colorectal cancer rates, especially in high-risk groups such as African Americans. Training primary care physicians (PCPs) to perform colonoscopy may improve screening rates among underserved high-risk populations. METHODS The authors compared colonoscopy screening rates and computed adjusted odds ratios for colonoscopy-eligible patients of trained African American PCPs (study group) versus untrained PCPs (comparison group), before and after initiating colonoscopy training. All colonoscopies were performed at a licensed ambulatory surgery center with specialist standby support. Retrospective chart review was conducted on 200 consecutive, established outpatients aged ≥50 years at each of 12 PCP offices (7 trained African American PCPs and 5 untrained PCPs, practicing in the same geographic region). There were a total of 1244 study group and 923 comparison group patients. RESULTS Post-training colonoscopy rates in both groups were higher than pretraining rates: 48.3% versus 9.3% in the study group, 29.6% versus 9.8% in the comparison group (both P < .001). African American patients in the study group showed a >5-fold increase (8.9% pretraining vs 52.8% post-training), with no change among whites (18.2% vs 25.0%). Corresponding pretraining and post-training rates among comparison patients were 10.4%% and 38.7%, respectively, among African Americans (P < .001), and 13.3% versus 13.2%, respectively, among whites. After adjusting for demographics, duration since becoming the PCP's patient, and health insurance, the study group had a 66% higher likelihood of colonoscopy in the post-training period (odds ratio, 1.66; 95% confidence interval, 1.30-2.13), and African Americans had a 5-fold increased likelihood of colonoscopy relative to whites. CONCLUSIONS Colonoscopy-trained PCPs may help reduce colorectal cancer disparities.

Abstract
Metabolomics represents one of the new omics sciences and capitalizes on the unique presence and concentration of small molecules in tissues and body fluids to construct a 'fingerprint' that can be unique to the individual and, within that individual, unique to environmental influences, including health and disease states. As such, metabolomics has the potential to serve an important role in diagnosis and management of human conditions. Colorectal cancer is a major public health concern. Current population-based screening methods are suboptimal and whether metabolomics could represent a new tool of screening is under investigation. The purpose of this systematic review is to summarize existing literature on metabolomics and colorectal cancer, in terms of diagnostic accuracies and distinguishing metabolites. Eight studies are included. A total of 12 metabolites (taurine, lactate, choline, inositol, glycine, phosphocholine, proline, phenylalanine, alanine, threonine, valine and leucine) were found to be more prevalent in colorectal cancer and glucose was found to be in higher proportion in control specimens using tissue metabolomics. Serum and urine metabolomics identified several other differential metabolites between controls and colorectal cancer patients. This article highlights the novelty of the field of metabolomics in colorectal oncology.

Abstract
The National Bowel Cancer Screening Program (NBCSP) offers population-based screening for colorectal cancer (CRC) across Australia. The aims of this paper were to highlight the inequities in CRC screening in South Australia (SA) and the system-related barriers and enablers to CRC screening from the perspective of participants identified as having inequitable participation. First, de-identified data for the SA population of the NBCSP were statistically analysed and then mapped. Second, 117 in-depth interviews were conducted with culturally and linguistically diverse (CALD) groups, Indigenous and Anglo-Saxon Australians. Participation rates in the NBCSP were geographically and statistically significantly different (P < 0.0001) on the basis of gender (higher for women), age (higher for older people) and socioeconomic status (higher for more affluent people). The main system-related barriers were the lack of awareness of CRC or CRC screening within these groups, the problems with language due to most of the information being in English and the lack of recommendation by a doctor. This study revealed that inequity exists in the NBCSP participation in SA, and we identified both barriers and facilitators to CRC screening that require action at the level of both policy and practice. There is a large role in primary health care of both recommending CRC screening and facilitating equitable participation.

Abstract
Colorectal cancer (CRC) represents a major cause of morbidity and mortality. Although it is widely accepted that CRC screening in average risk populations lowers CRC incidence and mortality, a disappointedly low adherence rate to both faecal occult blood testing and colonoscopy-based screening programs has been observed in Italy and in other European countries. Main reasons for the low acceptance of colonoscopy-based CRC screening has been ascribed to lack of recommendations given by general practitioners, fear of discomfort or complications, embarrassment, and avoidance of unpleasant preparation. New advances in endoscopic technology such as colon capsule and robotic colonoscopy might represent the ideal tool for CRC screening since they reduce or eliminate procedure-related pain and discomfort. Moreover, no disinfection between procedures is required. Motion of the new probes along the gastrointestinal tract is achieved either in passive modality by utilizing the gut peristalsis (colon capsule) or in active "intelligent" modality by means of computer-assisted propulsion (robotic colonoscopy). In this review, the preliminary clinical results obtained with the new devices are summarized. It is expected that the new instruments will be soon available in clinical practice with the hope of increasing adherence to CRC screening programs.

Abstract
AIMS One of the factors influencing the cost-effectiveness of population screening for Type 2 diabetes may be uptake. We examined attendance and practice- and individual-level factors influencing uptake at each stage of a diabetes screening programme in general practice. METHODS A stepwise screening programme was undertaken among 135, 825 people aged 40-69 years without known diabetes in 49 general practices in East England. The programme included a score based on routinely available data (age, sex, body mass index and prescribed medication) to identify those at high risk, who were offered random capillary blood glucose (RBG) and glycosylated haemoglobin tests. Those screening positive were offered fasting capillary blood glucose (FBG) and confirmatory oral glucose tolerance tests (OGTT). RESULTS There were 33 539 high-risk individuals invited for a RBG screening test; 24 654 (74%) attended. Ninety-four per cent attended the follow-up FBG test and 82% the diagnostic OGTT. Seventy per cent of individuals completed the screening programme. Practices with higher general practitioner staff complements and those located in more deprived areas had lower uptake for RBG and FBG tests. Male sex and a higher body mass index were associated with lower attendance for RBG testing. Older age, prescription of antihypertensive medication and a higher risk score were associated with higher attendance for FBG and RBG tests. CONCLUSIONS High attendance rates can be achieved by targeted stepwise screening of individuals assessed as high risk by data routinely available in general practice. Different strategies may be required to increase initial attendance, ensure completion of the screening programme, and reduce the risk that screening increases health inequalities.

What is most important to patients when deciding about colorectal screening? J Gen Intern Med 2010; 25:688-93. [PMID: 20309740 PMCID: PMC2881957 DOI: 10.1007/s11606-010-1318-9] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2009] [Revised: 10/20/2009] [Accepted: 02/16/2010] [Indexed: 12/16/2022]
Abstract
BACKGROUND Colorectal cancer (CRC) screening can be administered through tests with varied characteristics and is a preference-sensitive decision. OBJECTIVE To assess patient experiences with a Maximum Differences Scaling (MDS) tool for eliciting values about CRC screening test characteristics and determine whether patients vary in how they prioritize test characteristics and whether this variation relates to test preferences. DESIGN MDS survey to elicit patients' values for characteristics related to fecal occult blood testing, sigmoidoscopy, colonoscopy, CT colonography and colon capsule endoscopy. PARTICIPANTS 92 patients enrolled in primary care clinics at a VA hospital and associated university. RESULTS Patients reported that the tool was easy to use (95%). On completion 62% would choose colonoscopy, 23% colon capsule endoscopy and 10% CT colonography. Of the attributes evaluated, patients valued sensitivity, risk of tear and need for a second test most. Sensitivity was more important to those choosing colonoscopy than those choosing other tests (median importance = 21.5 versus 19.6, p < 0.01). Concern with complications and sedation was positively associated with age (p < 0.001 and p < 0.001), whereas concern with colon preparation and missing work was negatively associated with age (p < 0.009 and p < 0.03). Patients with fair or poor health status were less concerned with sensitivity than patients in good to excellent health (median importance = 19.3 versus 21.4, p < 0.008). CONCLUSIONS This pilot study suggests that patients vary in how they prioritize colorectal cancer screening test attributes; this variation is associated with test preferences, and this MDS tool is feasible to use and may help patients construct their preferences.

Abstract
OBJECTIVE To examine the coverage of colorectal cancer on Australian television news over a 3 year period commencing May 2005, and compare it with that given to other cancers. METHODS News reports on colorectal cancer broadcast on Sydney's five free-to-air television channels between 3 May 2005 and 30 May 2008 were reviewed for statements by news actors. The frequency of coverage was compared with that for other cancers. RESULTS Colorectal cancer news reports accounted for 4.1% (95% CI 2.9-5.1%) of all cancer news reports while the cancer represents 13.5% of cancer incidence and 11.5% of cancer deaths. Compared to cancers receiving greater television news coverage, there was a near total absence of reports of celebrity diagnoses, and of representations by colorectal advocacy groups. A national colorectal screening programme received limited coverage. CONCLUSIONS Media neglect of colorectal cancer may be an important factor in explaining low participation in the Australian colorectal screening programme. Those advocating for colorectal cancer screening face ingrained cultural challenges in gaining broad media coverage, but investment in efforts to generate news and commentary would appear to be overdue.

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