CHEYENNE, Wyo. (AP) — Serious problems persist at Wyoming's largest mental health facility four years after employees left an incapacitated woman on a couch without food, water or bathroom use for over 24 hours, according to two groups that provide legal and advocacy services to patients in need. They include a suicide, attempted suicides, the sexual assault of a patient by an employee, patient-on-patient and patient-on-staff assaults, incorrect medicine dosing and excessive patient restraint, said representatives of Wyoming Protection and Advocacy and Wyoming Guardianship Corp., which act as legal guardians for dozens of patients at Wyoming State Hospital. "There are systemic failures at the Wyoming State Hospital, some which have led to very serious and in some cases life-threatening conditions," Jeanne Thobro, director of Cheyenne-based Protection and Advocacy, told The Associated Press. Many of the problems stem from inadequate staffing, Thobro said.
