Recommendations From the International Colorectal Cancer Screening Network on the Evaluation of the Cost of Screening Programs.

ABSTRACT: Worldwide, colorectal cancer is the fourth leading cause of death from cancer and the incidence is projected to increase. Many countries are exploring the introduction of organized screening programs, but there is limited information on the resources required and guidance for cost-effective implementation. To facilitate the generating of the economics evidence base for program implementation, we collected and analyzed detailed program cost data from 5 European members of the International Colorectal Cancer Screening Network. The cost per person screened estimates, often used to compare across programs as an overall measure, varied significantly across the programs. In addition, there were substantial differences in the programmatic and clinical cost incurred, even when the same type of screening test was used. Based on these findings, several recommendations are provided to enhance the underlying methodology and validity of the comparative economic assessments. The recommendations include the need for detailed activity-based cost information, the use of a comprehensive set of effectiveness measures to adequately capture differences between programs, and the incorporation of data from multiple programs in cost-effectiveness models to increase generalizability. Economic evaluation of real-world colorectal cancer-screening programs is essential to derive valuable insights to improve program operations and ensure optimal use of available resources.

Project description:BACKGROUND: With 14.234 diagnoses and over 4047 deaths reported in 2007, colorectal cancer (CRC) is the second most common cancer and second most common cause of cancer-related mortality in Australia. The direct treatment cost has recently been estimated to be around AU$1.2 billion for the year 2011, which corresponds to a four-fold increase, compared the cost reported in 2001. Excluding CRCs due to known rare genetic disorders, 20% to 25% of all CRCs occur in a familial aggregation setting due to genetic variants or shared environmental risk factors that are yet to be characterised. A targeted screening strategy addressed to this segment of the population is a potentially valuable tool for reducing the overall burden of CRC. METHODS: We developed a Markov model to assess the cost-effectiveness of three screening strategies offered to people at increased risk due to a strong family history of CRC. The model simulated the evolution of a cohort of 10,000 individuals from age 50 to 90 years. We compared screening with biennial iFOBT, five-yearly colonoscopy and ten-yearly colonoscopy versus the current strategy of the Australian National Bowel Cancer Screening Programme (i.e. base case). RESULTS: Under the NBCSP scenario, 6,491 persons developed CRC with an average screening lifetime cost of AU$3,441 per person. In comparison, screening with biennial iFOBT, colonoscopy every ten years, and colonoscopy every five years reduced CRC incidence by 27%, 35% and 60%, and mortality by 15%, 26% and 46% respectively. All three screening strategies had a cost under AU$50,000 per life year gained, which is regarded as the upper limit of acceptable cost-effectiveness in the Australian health system. At AU$12,405 per life year gained and an average lifetime expectancy of 16.084 years, five-yearly colonoscopy screening was the most cost-effective strategy. CONCLUSION: The model demonstrates that intensive CRC screening strategies targeting people at increased risk would be cost-effective in the Australian context. Our findings provide evidence that substantial health benefits can be generated from risk-based CRC screening at a relatively modest incremental cost.

Project description:ImportanceGuidelines for colorectal cancer (CRC) screening recommend an individualized approach in older adults that is informed by consideration of life expectancy and cancer risk. However, little is known about how patients perceive individualized screening recommendations.ObjectiveTo assess veterans' attitudes toward and comfort with cessation of low-value CRC screening (defined as screening in a patient for whom the benefit is expected to be small based on quantitative estimates from hypothetical risk calculators).Design, setting, and participantsThis survey study included patients older than 50 years who had undergone prior screening colonoscopy with normal results at the Veterans Affairs Ann Arbor Healthcare System. A total of 1500 surveys were mailed to potential participants from November 1, 2010, to January 1, 2012. Survey data were analyzed from January 1, 2016, to December 31, 2017.Main outcomes and measuresResponse to the question, "If you personally had serious health problems that were likely to shorten your life and your doctor did not think screening would be of much benefit based on the calculator, how comfortable would you be with not getting any more screening colonoscopies?"ResultsOf the 1500 surveys mailed, 85 were returned to sender, leaving 1415 potential respondents; 1054 of these respondents (median age range, 60-69 years; 884 [85.9%] white and 965 [94.2%] male) completed the survey (response rate, 74.5%). A total of 300 (28.7%) were not at all comfortable with cessation of low-value CRC screening, and 509 (49.3%) thought that age should never be used to decide when to stop screening. In addition, 332 (31.7%) thought it was not at all reasonable to use life expectancy calculators, and 255 (24.3%) thought it was not at all reasonable to use CRC risk calculators to guide these decisions. In ordered logistic regression analysis, factors associated with more comfort with screening cessation were (1) higher trust in physician (odds ratio [OR], 1.19; 95% CI, 1.07-1.32), (2) higher perceived health status (OR, 1.41; 95% CI, 1.23-1.61), and (3) higher barriers to screening (OR, 1.20; 95% CI, 1.11-1.30). Factors that were associated with less comfort with screening cessation included (1) greater perceived effectiveness of screening (OR, 0.86; 95% CI, 0.80-0.94) and (2) greater perceived threat of CRC (OR, 0.81; 95% CI, 0.73-0.89).Conclusions and relevanceThe findings suggest that many veterans have strong preferences against screening cessation even when given detailed information about why the benefit may be low. Efforts to tailor screening recommendations may be met by resistance unless they are accompanied by efforts to address underlying perceptions about the benefit of screening.
