The answer depends on the goals that have medical personnel. Well, in any case these goals will be related to keeping people healthier by curating medical problems and respective preventive actions, but the formulation of this goals and how they are aligned with overall strategy of medical organization are important, including for the definition of the KPIs.
Here is what I can recommend:
