Assessing Stated Preferences for Colorectal Cancer Screening: A Critical Systematic Review of Discrete Choice Experiments

Abstract

Understanding and incorporating individuals' preferences in decision making is increasingly considered essential in the health field. Data from DCEs can provide valuable insights into the trade-offs individuals are willing to undertake in respect to CRC screening. Such insights can be used by decision makers to identify screening tests that could maximize informed uptake. It is likely that, with better reporting and evolving methodology, the contribution that DCEs can make to such debates will increase.

Colorectal cancer screening in the familial risk population: Is colonoscopy still the strategy of choice?

“…A recent systematic review about preferences in the averagerisk population failed to conclude which test was preferred because of a high heterogeneity across the studies. 73 However, most studies agree that the preferred test should be sufficiently sensitive, it should last a short time, it should not require bowel preparation and it should entail no risk of complications. As this type of test does not exist, there was no single strategy that was unanimously preferred.…”

Public Preferences for Lung Cancer Screening Policies

“…Understanding the preferences of the eligible population with regard to attributes of screening policies may help policymakers to further design the screening by selecting those attribute levels that maximize screening attendance. In addition, it will help policymakers to tailor information provision for people targeted for the screening [9]. Achieving high attendance (particularly of high-risk subpopulations) is important to realize the reduction in cancer-related mortality suggested in cancer screening trials.…”

“…Studies performed alongside lung cancer screening trials reported that smoking status, perceived risk of lung cancer, and result of baseline computed tomography scan were indicative of adherence to the screening protocol [10][11][12][13][14]. To obtain quantitative insights into the relative importance of attributes of lung cancer screening, stated preference methods can be used [9,15,16]. Stated preference questionnaires present respondents with direct questions about their preferences or have respondents make hypothetical decisions from which preferences are subsequently inferred.…”

“…These types of methods are increasingly used in health care [15,17], but no results from stated preference studies for lung cancer screening are known [18]. There have, however, been stated preference studies in the context of screening for other types of cancer, namely, breast [16], colorectal [9,[19][20][21][22], and prostate [23][24][25] cancer. Common findings in these studies were that the most important attribute according to respondents was test accuracy, and that respondents indicated a higher willingness to attend if they had a higher self-perceived risk of cancer.…”
