MEXICO, Missouri — When the new corporate owners of two rural hospitals suddenly announced they would stop admitting patients one Friday in March, Kayla Schudel, a nurse, stood resolute in the nearly empty lobby of Audrain Community Hospital: “You’ll be seen; the ER is open.”

The hospital — with 40 beds and five clinics — typically saw 24 to 50 emergency room cases a day, treating patients from the surrounding 1,000-plus acre farms and tiny no-stoplight towns, she said. She wouldn’t abandon them.
