New York City health officials have reinstated an indoor mask advisory for all residents, regardless of vaccination status—in today's bite-sized hospital and health industry news from Minnesota, New York, and Ohio.

• Minnesota: UnitedHealth Group has appointed Margaret-Mary Wilson as executive vice president and CMO. Wilson—who has been with UnitedHealthcare since 2008—previously served as associate professor of internal and geriatric medicine at St. Louis University. This year, the National Diversity Council recognized Wilson as one of the top 100 most influential African Americans in business, and Diversity Journal recognized her as one of its top 100 "elite women." "I'm honored to be named the next CMO of UnitedHealth Group," Wilson said. "This is an incredible time to be in health care and I look forward to working with my 340,000 colleagues to address some of the health system's critical needs and most exciting opportunities."

• New York: Amid concerns over the spread of the new omicron variant, New York City health officials on Monday issued a mask advisory—urging both vaccinated and unvaccinated residents to wear a mask in public indoor settings. Currently, there are no confirmed cases of omicron in the United States. However, New York City health officials said they expect to see cases of the new variant within the next few days. According to New York City health commissioner Dave Chokshi, "We do anticipate detecting omicron in New York City in the coming days based on what we know about its global spread." While studies on the variant are still ongoing, early evidence has suggested that it could increase the likelihood of reinfection. (Carbajal, Becker's Hospital Review, 11/29)

• Ohio: Akram Boutros on Monday announced that he will retire as president and CEO of MetroHealth at the end of 2022. Boutros joined the health system in 2013 to oversee its transformation and help establish long-term sustainability. According to MetroHealth board chair Vanessa Whiting, Boutros has since "exceeded the board's, employees' and the community's expectations." During his tenure, the health system has opened two additional hospitals, three EDs, ten community health centers, nine pharmacies, and seen an annual revenue growth from $785 million to over $1.5 billion.
