Abstract for: A System Dynamics Model to Scrutinize Underlying Reasons for Poor Prescription Adherence (Case Study: Antibiotic Consumption)

Poor prescription adherence is a common problem that can lessen the effectiveness of medications and increase health expenditures. Using the system dynamics approach, this paper investigates the underlying structure that causes poor prescription adherence. Literature review reveals that no research has been done in this regard, and this study (to the best of our knowledge) is the first step to bridge this theoretical gap. The research outcome is a qualitative causal loop diagram (CLD) including 12 loops that could be further examined and validated to understand their role in poor prescription adherence. Developing a quantitative model from a validated and thoroughly reviewed qualitative model will add value to this paper. The qualitative model then can be used to test the effectiveness of policies suggested to increase prescription adherence.
