A2-1: Patterns of Colorectal Cancer Testing in Men and Women Newly Eligible for Screening.

ABSTRACT: Background/AimsSince 1993, the US Preventive Services Task Force has recommended screening to prevent colorectal cancer among average risk adults, beginning at age 50. Many studies over the past 20 years evaluated factors associated with screening uptake; however, few have focused on individuals who are newly eligible (i.e., those turning 50 years). We evaluated patient characteristics associated with uptake and time to initiation of colorectal cancer tests in a population newly-eligible for screening.MethodsThe study included 128,358 individuals who were members of an integrated care delivery system (Group Health) and enrolled on their 50th birthday from 1996–2011. We assessed receipt of colorectal cancer tests within 5 years of eligibility, and calculated the median time to first test. We examined patient characteristics associated with use of colorectal cancer tests overall using Cox proportional hazards models.ResultsStool-based tests were most commonly used, with uptake ranging from 35–40% of the cohort across the study period. The proportion of individuals initiating colorectal cancer testing via colonoscopy increased from 3% in members becoming eligible in 1996–1998 to 21% in 2005–2007. Time to first test varied across test types. Median time to the first test was 3 months shorter in members who chose stool-based tests (25.2 months) compared to those who chose colonoscopy (28.2 months) among members newly eligible in 2005–2007. However, we observed no temporal changes in median time to first test, conditional on test type. Characteristics associated with increased uptake included more recent enrollment at age 50 (e.g., 2008–2010:HR = 2.16, 95% CI 2.09–2.23) and Asian background (HR = 1.08, 95% CI 1.05–1.11). Factors associated with reduced uptake included being a woman (HR = 0.93, 95% CI 0.91–0.94), African-American (HR = 0.95, 95% CI 0.91–0.99) or Pacific Islander (HR = 0.86, 95% CI 0.76–0.96), diagnosed with diabetes (HR = 0.88, 95% CI 0.85–0.91) and being moderately or severely obese (HR = 0.83, 95% CI 0.81–0.85 and HR = 0.75, 95% CI 0.73–0.77, respectively).ConclusionsPatient characteristics associated with initiation of colorectal cancer testing in a newly eligible population are similar to previous findings among all-age eligible adults. Further, while the time to the first test remained stable, there was an increase in colorectal cancer testing during the study period.

Project description:BackgroundScreening is defined as the identification of unrecognized disease in an apparently healthy population. Symptomatic individuals are recommended to contact a physician instead of participating in screening. However, in colorectal cancer (CRC) screening this approach may be problematic as abdominal symptoms are nonspecific. This study aimed at identifying the prevalence of self-reported abdominal symptoms among screening-eligible men and women aged 50-74 years.MethodsThis cross-sectional survey study included 11,537 individuals aged 50-74 years invited for CRC screening from 9 to 23 September 2019. Descriptive statistics of responders experiencing alarm symptoms of CRC, Low Anterior Resection Syndrome Score (LARS) and the Patient Assessment of Constipation-Symptoms (PAC-SYM) were derived. The association between abdominal symptoms and demographic and socioeconomic variables were estimated by prevalence ratio (PR) using a Poisson regression model with robust variance.ResultsA total of 5488 respondents were included. The respondents were more likely women, of older age, Danish, cohabiting and had higher education and income level compared to non-respondents. Abdominal pain more than once a week was experienced by 12.0% of the respondents. Of these, 70.8% had been experiencing this symptom for >1 month. Fresh blood in the stool was experienced by 0.7% and of these 82.1% for >1 month. About one third of those experiencing alarm symptoms more than once a week for >1 month had not consulted a doctor. A total of 64.1% of the respondents had no LARS, 21.7% had minor LARS and 14.2% had major LARS. The median PAC-SYM score was 0.33 (Interquartile range (IQR): 0.17;0.75), the median abdominal score was 0.50 (IQR: 0.00;1.00), median rectal score 0.00 (IQR:0.00;0.33) and median stool score 0.40 (IQR: 0.00;0.80). Men and those aged 65-74 reported less symptoms than women and those aged 50-64 years, respectively.ConclusionsThis study illustrated that abdominal symptoms were frequent among screening-eligible men and women. This should be taken into account when implementing and improving CRC screening strategies. A concerning high number of the respondents experiencing alarm symptoms had not consulted a doctor. This calls for attention to abdominal symptoms in general and how those with abdominal symptoms should participate in CRC screening.

Project description:INTRODUCTION:Despite healthcare reforms mandating expanded insurance coverage and reduced out-of-pocket costs for preventive care, cancer screening rates remain relatively static. No study has measured cancer screening rates for multiple tests among non-Medicare patients. METHODS:This retrospective, population-based claims analysis, conducted in 2016-2017, of commercially insured and Medicaid-insured women aged 30-59 years enrolled in IBM MarketScan Commercial and Medicaid Databases (containing approximately 90 and 17 million enrollees, respectively) during 2010-2015 describes screening rates for breast, cervical, and colorectal cancer. Key outcomes were (1) proportion screened for breast, cervical, and colorectal cancer among the age-eligible population compared with accepted age-based recommendations and (2) proportion with longer-than-recommended intervals between tests. RESULTS:One half (54.7%) of commercially insured women aged 40-59 years (n=1,538,444) were screened three or more times during the 6-year study period for breast cancer; for Medicaid-insured women (n=78,897), the rates were lower (23.7%). One third (43.4%) of commercially insured and two thirds (68.9%) of Medicaid-insured women had a >2.5-year gap between mammograms. Among women aged 30-59 years, 59.3% of commercially insured women and 31.4% of Medicaid-insured women received two or more Pap tests. The proportion of patients with a >3.5-year gap between Pap tests was 33.9% (commercially insured) and 57.1% (Medicaid-insured). Among women aged 50-59 years, 63.3% of commercially insured women and 47.2% of Medicaid-insured women were screened at least one time for colorectal cancer. Almost all women aged 30-59 years (commercially insured, 99.1%; Medicaid-insured, 98.9%) had at least one healthcare encounter. CONCLUSIONS:Breast and cervical cancer screenings remain underutilized among both commercially insured and Medicaid-insured populations, with lower rates among the Medicaid-insured population. However, almost all women had at least one healthcare encounter, suggesting opportunities for better coordinated care.

Project description:BackgroundCancer screening programmes in England are publicly-funded. Professionals' beliefs in the public health benefits of screening can conflict with individuals' entitlements to exercise informed judgement over whether or not to participate. The recognition of the importance of individual autonomy in decision making requires greater understanding of the knowledge, attitudes and beliefs upon which people's screening choices are founded. Until recently, the technology available required that cancer screening be confined to women. This study aimed to discover whether male and female perceptions of cancer and of screening differed.MethodsData on the public's cancer beliefs were collected by means of a postal survey (anonymous questionnaire). Two general practices based in Nottingham and in Mansfield, in east-central England, sent questionnaires to registered patients aged 30 to 70 years. 1,808 completed questionnaires were returned for analysis, 56.5 per cent from women.ResultsWomen were less likely to underestimate overall cancer incidence, although each sex was more likely to cite a sex-specific cancer as being amongst the most common cancer site. In terms of risk factors, men were most uncertain about the role of stress and sexually-transmitted diseases, whereas women were more likely to rate excessive alcohol and family history as major risk factors. The majority of respondents believed the public health care system should provide cancer screening, but significantly more women than men reported having benefiting from the nationally-provided screening services. Those who were older, in better health or had longer periods of formal education were less worried about cancer than those who had illness experiences, lower incomes, or who were smokers. Actual or potential participation in bowel screening was higher amongst those who believed bowel cancer to be common and amongst men, despite women having more substantial worries about cancer than men.ConclusionOur results suggest that men's and women's differential knowledge of cancer correlates with women's closer involvement with screening. Even so, men were neither less positive about screening nor less likely to express a willingness to participate in relevant screening in the future. It is important to understand gender-related differences in knowledge and perceptions of cancer, if health promotion resources are to be allocated efficiently.

Project description:Background:The long-term effects of sigmoidoscopy screening on colorectal cancer (CRC) incidence and mortality in women and men are unclear. Objective:To determine the effectiveness of flexible sigmoidoscopy screening after 15 years of follow-up in women and men. Design:Randomized controlled trial. (ClinicalTrials.gov: NCT00119912). Setting:Oslo and Telemark County, Norway. Participants:Adults aged 50 to 64 years at baseline without prior CRC. Intervention:Screening (between 1999 and 2001) with flexible sigmoidoscopy with and without additional fecal blood testing versus no screening. Participants with positive screening results were offered colonoscopy. Measurements:Age-adjusted CRC incidence and mortality stratified by sex. Results:Of 98 678 persons, 20 552 were randomly assigned to screening and 78 126 to no screening. Adherence rates were 64.7% in women and 61.4% in men. Median follow-up was 14.8 years. The absolute risks for CRC in women were 1.86% in the screening group and 2.05% in the control group (risk difference, -0.19 percentage point [95% CI, -0.49 to 0.11 percentage point]; HR, 0.92 [CI, 0.79 to 1.07]). In men, the corresponding risks were 1.72% and 2.50%, respectively (risk difference, -0.78 percentage point [CI, -1.08 to -0.48 percentage points]; hazard ratio [HR], 0.66 [CI, 0.57 to 0.78]) (P for heterogeneity = 0.004). The absolute risks for death from CRC in women were 0.60% in the screening group and 0.59% in the control group (risk difference, 0.01 percentage point [CI, -0.16 to 0.18 percentage point]; HR, 1.01 [CI, 0.77 to 1.33]). The corresponding risks for death from CRC in men were 0.49% and 0.81%, respectively (risk difference, -0.33 percentage point [CI, -0.49 to -0.16 percentage point]; HR, 0.63 [CI, 0.47 to 0.83]) (P for heterogeneity = 0.014). Limitation:Follow-up through national registries. Conclusion:Offering sigmoidoscopy screening in Norway reduced CRC incidence and mortality in men but had little or no effect in women.
