The HPRA is tasked with market surveillance and also seems to have a requirement to talk to patients and doctors to fill that requirement of market surveillance. HIQA has a requirement to oversee patient safety. What is the communication between HIQA and the HPRA and what are the interactions there? There seems to be an overlap in function and I am trying to understand where the lines are there.
