The webinar outlines requirements for the model design proposal under the state innovation models initiative, focusing on the 'population health plan' segment, which aims to improve population health through a structured narrative. Applicants are expected to develop a close-to-final outline of this plan over a 12-month period, adhering to specific formatting and page limits across various components of the project narrative. Key deliverables include defining core population health metrics and collaboration with public and private health stakeholders to integrate strategies addressing significant health issues such as tobacco use, diabetes, and obesity.
