The document discusses using the Unified Modeling Language (UML) to model the e-prescribing process in Italy. UML can help manage the complexity of modeling a prescribing process, which involves the transition from diagnosis to treatment and needs continuous monitoring. It allows formal specification of actors, interactions, and object properties. This can help control the full process, validate actions, and prevent errors and omissions, thereby improving safety. The presentation provides examples of how UML can be used to model different aspects of e-prescribing.
