Abstract
Projects of case management of older persons were implemented in Belgium. This type of long-term healthcare interventions presents many aspects of complexity including human interactions and contextual effects. Computer simulation enables to mix advantages of classic qualitative and quantitative analyses to assess why differences in the implementation of these projects led to failure or success. A simulation model of case management was designed using a Rule-Based Methodology. Based on the research material, variables and rules definitions were elicited into a simple conceptual frame. The simulation was then confronted to field experts. The rigorous formulation clarified the description of the interventions. Parametric analyses were performed with the experts. Problems and adaptation processes were reported. Eventually, a number of recommendations were addressed. The simulation model presented should be seen primarily as a tool for thinking and learning. The computer simulation can help to unfold causal mechanisms of complex interventions.
