Patient Preferences for Colorectal Cancer Screening Tests in Light of Lowering the Screening Age to 45 Years.

ABSTRACT:

Background & aims

In 2021, the US Preventive Services Task Force lowered the colorectal cancer (CRC) screening age to 45 years. We used conjoint analysis, a method that assesses complex decision making, to update our understanding on people's CRC screening test preferences in the context of new guidelines.

Methods

We conducted a conjoint analysis survey among unscreened individuals ≥40 years at average risk for CRC to determine the relative importance of screening test attributes in their decision making (eg, modality, effectiveness at reducing CRC risk, bowel prep). We also performed simulations to estimate the proportion of people who would prefer each US Multi-Society Task Force (MSTF) on CRC-recommended test. The analyses were stratified among those aged 40-49 years (newly or soon-to-be eligible for screening) and ≥50 years (have been eligible).

Results

Overall, 1000 participants completed the conjoint analysis (40-49 years, n = 456; ≥50 years, n = 544). When considering all 5 US MSTF-recommended tests, there were differences in test preferences between age groups (P = .019), and the most preferred test was a fecal immunochemical test (FIT)-fecal DNA every 3 years: 40-49 years, 34.6%; ≥50 years, 37.3%. When considering only the US MSTF tier 1 tests, most 40- to 49- (68.9%) and ≥50-year-olds (77.4%; P = .004) preferred an annual FIT over a colonoscopy every 10 years.

Conclusions

Our findings suggest that more than one-third of people may want to do a FIT-fecal DNA every 3 years for their CRC screening. When only considering US MSTF tier 1 tests, three-fourths of people may prefer an annual FIT over colonoscopy. Further research examining CRC screening test preferences among broader populations is warranted to inform and enhance screening programs.

Project description:Background and objectiveColorectal cancer (CRC) is one of the most common cancers in Europe. Recently, new data from the USA and Europe revealed an increase in the incidence of CRC in individuals aged <55 years and a reduction in those aged >65 years. Mortality rate was stable in patients aged <55 years and decreased after the age of 55 years. Based on the USA data, the American Cancer Society (ACS) published a qualified recommendation advocating the start of CRC screening at the age of 45 years. We aimed to evaluate if the changes in the CRC incidence/mortality observed in the USA and the rest of Europe also occur in Portugal, and then perform a cost-utility analysis of CRC screening that starts at 45 years of age.MethodsWe evaluated the incidence of CRC by age group using data from the National Cancer Registry, and the mortality rate according to the National Statistics Institute in the periods 1993-2010 and 2003-2016. A cost-utility analysis was performed with a decision tree from a societal perspective comparing biennial fecal immunochemical test (FIT) or a single colonoscopy screening versus nonscreening at the age of 45 years in Portugal.ResultsIn Portugal, in 1993-2010, there was an increase in CRC incidence of 17% (from 25 to 30/100,000), 35% (from 39 to 54/100,000), and 71% (from 52 to 97/100,000) in patients aged 45-49 years, 50-54 years, and 55-59 years, respectively. The mortality rate of patients aged 45-54 years remained stable between 2003 and 2016 (12/100,000) as a counterpoint to a moderate decrease in those aged 55-64 years (from 38 to 35/100,000) and a sharp reduction in those aged 65-75 years (from 93 to 75/100,000). Screening for CRC at the age of 45 years has no cost utility with the current incidence. FIT screening provided an ICUR of EUR 84,304/quality-adjusted life years (QALY) while colonoscopy provided an ICUR of EUR 3,112,244/QALY. On one-way sensitivity analysis, FIT screening would only have cost utility at the present cost of colonoscopy under sedation (EUR 150) and acceptance rates if the incidence rate rises above 47.5/100,000; colonoscopy at this age would have no cost utility despite changes in costs and/or incidence rates.ConclusionIn Portugal, the incidence of CRC in patients aged 45-55 years has been increasing with a stable mortality rate, in contrast to the decrease in mortality in the age groups covered by the current CRC screening program. However, at present, CRC screening in Portugal at the age of 45 years has no cost utility and will only have this if the incidence rate rises above 47.5/100,000 (vs. the actual incidence of 30/100,000).

Project description:BackgroundEmerging blood-based multi-cancer early detection (MCED) tests can detect a variety of cancer types across stages with a range of sensitivity, specificity, and ability to predict the origin of the cancer signal. However, little is known about the general US population's preferences for MCED tests.ObjectiveTo quantify preferences for MCED tests among US adults aged 50-80 years using a discrete choice experiment (DCE).MethodsTo quantify preferences for attributes of blood-based MCED tests, an online DCE was conducted with five attributes (true positives, false negatives, false positives, likelihood of the cancer type unknown, number of cancer types detected), among the US population aged 50-80 years recruited via online panels and social media. Data were analyzed using latent class multinomial logit models and relative attribute importance was obtained.ResultsParticipants (N = 1700) were 54% female, mean age 63.3 years. Latent class modeling identified three classes with distinct preferences for MCED tests. The rank order of attribute importance based on relative attribute importance varied by latent class, but across all latent classes, participants preferred higher accuracy (fewer false negatives and false positives, more true positives) and screenings that detected more cancer types and had a lower likelihood of cancer type unknown. Overall, 72% of participants preferred to receive an MCED test in addition to currently recommended cancer screenings.ConclusionsWhile there is significant heterogeneity in cancer screening preferences, the majority of participants preferred MCED screening and the accuracy of these tests is important. While the majority of participants preferred adding an MCED test to complement current cancer screenings, the latent class analyses identified a small (16%) and specific subset of individuals who value attributes differently, with particular concern regarding false-negative and false-positive test results, who are significantly less likely to opt-in.

Project description:ImportanceIn May 2021, the US Preventive Services Task Force (USPSTF) issued a grade B recommendation encouraging colorectal cancer (CRC) screening among average-risk individuals aged 45 to 49 years. The patterns of screening uptake and possible socioeconomic disparities in screening in this age group remain unknown.ObjectiveTo evaluate changes in CRC screening uptake among average-risk individuals aged 45 to 49 years after the USPSTF recommendation was issued in 2021.Design, setting, and participantsThis retrospective cohort study used deidentified claims data from commercially insured Blue Cross Blue Shield beneficiaries aged 45 to 49 years across the US between January 1, 2017, and December 31, 2022.ExposurePublication of the May 2021 USPSTF CRC screening recommendation for adults aged 45 to 49 years.Main outcomes and measuresAbsolute and relative changes in screening uptake were compared between a 20-month period preceding (May 1, 2018, to December 31, 2019) and a 20-month period following (May 1, 2021, to December, 31, 2022) the USPSTF recommendation. Interrupted time-series analysis and autoregressive integrated moving average models were used to evaluate changes in screening rates, adjusting for temporal autocorrelation and seasonality.ResultsIn this cohort study of 10 221 114 distinct beneficiaries aged 45 to 49 years (mean [SD] age, 47.04 [1.41] years; 51.04% female), bimonthly mean (SD) numbers of average-risk beneficiaries were 3 213 935 (31 508) and 2 923 327 (105 716) in the prerecommendation and postrecommendation periods, respectively. Mean (SD) screening uptake increased from 0.50% (0.02%) to 1.51% (0.59%) between the 2 periods (P < .001), representing an absolute change of 1.01 percentage points (95% CI, 0.62-1.40 percentage points) but no significant relative change (202.51%; 95% CI, -30.59% to 436.87%). Compared with average-risk beneficiaries residing in areas with the lowest socioeconomic status (SES), those residing in areas with the highest SES experienced the largest absolute change in screening (1.25 [95% CI, 0.77-1.74] percentage points vs 0.75 [95% CI, 0.47-1.02] percentage points), but relative changes were not significant (214.01% [95% CI, -30.91% to 461.15%] vs 167.73% [95% CI, -16.30% to 352.62%]). After the recommendation was issued, the screening uptake rate also increased fastest among average-risk beneficiaries residing in the areas with highest SES (0.24 [95% CI, 0.23-0.25] percentage points every 2 months) and metropolitan areas (0.20 [95% CI, 0.19-0.21] percentage points every 2 months).Conclusions and relevanceThis study found that among privately insured beneficiaries aged 45 to 49 years, CRC screening uptake increased after the USPSTF recommendation, with potential disparities based on SES and locality.
