What are GPs' preferences for financial and non-financial incentives in cancer screening? Evidence for breast, cervical, and colorectal cancers.
General practitioners (GPs) play a key role in the delivery of preventive and screening services for breast, cervical, and colorectal cancers. In practice, GPs' involvement varies considerably across types of cancer and among GPs, raising important questions about the determinants of GPs' implication in screening activities: what is the relative impact of financial and non-financial incentives? Are GPs' preferences for financial and non-financial incentives cancer-specific? Is there preference heterogeneity and how much does it differ according to the screening context? This study investigates the determinants of GPs' involvement in cancer screening activities using the discrete choice experiment (DCE) methodology. A representative sample of 402 GPs' was recruited in France between March and April 2014. Marginal rates of substitution were used to compare GPs' preferences for being involved in screening activities across three types of cancers: breast, cervical, and colorectal. Variability of preferences was investigated using Hierarchical Bayes mixed logit models. The results indicate that GPs are sensitive to both financial and non-financial incentives, such as a compensated training and systematic transmission of information about screened patients, aimed to facilitate communication between doctors and patients. There is also evidence that the level and variability of preferences differ across screening contexts, although the variations are not statistically significant on average. GPs appear to be relatively more sensitive to financial incentives for being involved in colorectal cancer screening, whereas they have higher and more heterogeneous preferences for non-financial incentives in breast and cervical cancers. Our study provides new findings for policymakers interested in prioritizing levers to increase the supply of cancer screening services in general practice.
