Towards Accurate Prediction of Healthcare Choices: The INTERSOCIAL Project
Accurate prediction of choices is needed to avoid poor policy decisions, trial-and-error implementation, and demand-supply imbalance. This is especially valuable for healthcare, since health systems are under pressure due to rising expenditures, an ageing population, high prices of new medical treatments, and substantial medication waste occurring every year. However, current models of individual decision-makers (e.g., patients, healthcare professionals) analyse their choices as if they are independent of other people’s influences. This hampers accurate ex-ante evaluation of healthcare policies, as most healthcare choices are not made in a social vacuum!
Moving towards a social interdependent choice paradigm is crucial to reach accurate choice-modelling in healthcare (not to mention other areas of policy interest). This important, urgent and challenging step is at the heart of this project entitled INTERSOCIAL, the acronym for the project ‘Towards a Social Interdependent Choice Paradigm for Ex-Ante Evaluation of Healthcare Policies’, a five-year research project funded by the Dutch Research Council (NWO).
INTERSOCIAL develops and validates a social-interdependent choice paradigm to integrate social influences into choice models in healthcare. This project takes this step by undertaking three interrelated phases:
- Phase I develops a theory of socially interdependent decision-making, primarily to achieve accurate predictions of choice behaviour in healthcare;
- Phase II translates this theory into a methods paradigm: how to measure and model stated choices for socially interdependent decisions to improve prediction of real-world choice behaviour;
- Phase III validates the paradigm developed in four different medical areas to establish generalisability of the results.
INTERSOCIAL has the potential to deliver a range of ground-breaking contributions to the fields of choice modelling, choice behaviour prediction, and decision-making in healthcare.
