Building and Landing the Plane While Flying: How New York State Addressed the Needs of People With Serious Mental Illness During the COVID-19 Pandemic.

New York State was the epicenter for COVID-19 in Spring 2020 when little was known about the pandemic. Dire circumstances necessitated New York State's (NYS) public mental health system to rapidly pivot, adapt, and innovate its policies and procedures to ensure continuous high-level care to individuals with serious mental illness (SMI), a population especially vulnerable to both the physical and psychosocial sequelae of COVID-19. NYS rapidly adopted emergency measures to support community providers, expanded the capacity of its State-Operated facilities, created policies to promote improved infection control access, collaborated to enhance the public-private continuum of service to support people with SMI, and broadened the use of new technologies to ensure continued engagement of care.
