Responding to the COVID-19 pandemic materially amplified Northwell Health’s necessary speed from question to answer. At the peak of the pandemic, Northwell, one of the hardest hit healthcare systems in the United States, had to manage an evolving cohort definition for COVID-19, an additional 200 beds daily, and new healthcare professionals from across the country. Navigating this crisis required careful planning, communication, coordination, and research, which necessitated unprecedented collaboration, an extensive patient registry, access to key datasets, geocoding, and serology testing. Learn about the data-driven response Northwell Health implemented from day one of the pandemic, the successes and lessons learned, and how organizations can use technology and analytics for future infection tracking and patient care. During this webinar, Chris Hutchins, Vice President, Chief Data and Analytics Officer, Northwell Health, offers the following: - Share strategies to navigate COVID-19. - Identify how to use data marts to drive self-service analytics. - Delve into strategies to drive transformation. - Help you understand why you should design a flexible model for a cohort definition. - Explain how to align critical resources to enable rapid response.
