Elicitation of Preference and Shared Decision Making in Screening Programs
General context of the project:
It is currently accepted that screening programs or early detection programs, present not only benefits, but also adverse effects (e.g., overdiagnosis and false positives).
In these programs, there are several alternatives and high uncertainty about the best possible option. The shared decision-making model (SDM) between health professionals and patients can help to decrease the undesirable side effects of unilateral decisions.
Therefore, in order to increase the benefits of the screening programs, we should take into account:
a. The patient’s preferences, and
b. The collaboration of both, professionals and patients, in order to decide the participation or not of patients in the screening program.
a. The Stated preference approaches use hypothetical data to estimate preferences of health outcomes. The joint analysis methods can be used to assess and quantify the relative weights of the process and result attributes of the screening programs.
The stated preference methods have a conceptual basis in the neoclassical theory of consumer utility (ordinal utility), which assumes that utility associated with every alternative is a function of the observed and unobserved characteristics (attribute levels).
b. The SDM environment improves patients well-being. However, there are no clear results on how to encourage the participation of professionals in this process.
The barriers perceived by professionals are lack of time and training, and the patients’ emotional and cognitive abilities. Additionally, professionals may also need updated information about options and results of the different screening programs.
General: To improve the performance of the screening programs, by encouraging proactive participation of health professionals in SDM and by evaluating the diverse alternatives based on the preferences of the patients.
a. To apply joint analysis methods to elicit the preferences of the patients.
b. To use qualitative analysis techniques (e.g. focal groups, in depth interviews, deliberative juries) to identify the information needs of health professionals regarding the screening programs and to analyze their beliefs and attitudes regarding SDM.
