Modelling the Medication Management System for Resource Limited Settings: A Formal Representation of the Prescribing and Dispensing Phases.

We propose a conceptual data model for relational databases targeting the prescribing and dispensing phases of the medication management system. The model was developed using recommendations from existing standards and guidelines, with necessary modifications made to suit adoption in resource-limited settings. We present the model as an entity-relationship diagram with 10 entities, 12 relationships and 48 attributes. It is our hope that this work will help mitigate barriers in the implementation of electronic prescribing and dispensing standards in the developing world.
