The San Antonio State Hospital (SASH) is one of ten state mental health facilities within the Texas Department of State Health Services (DSHS) system. SASH provides intensive inpatient diagnostic, treatment, rehabilitative, and referral services for seriously mentally ill persons from South Texas regardless of their financial status. Admission may be voluntary or involuntary depending on whether the patient is determined by a court to be seriously mentally ill, dangerous to self or others, or if left untreated would deteriorate to the point of becoming dangerous to self or others. SASH attempts to involve the patient's family in the treatment/rehabilitation process to the degree legally and clinically feasible.
The hospital's distinctions include the Seidel Learning Center, a partnership with the San Antonio Independent School District.
San Antonio State Hospital is accredited by the Joint Commission. The Joint Commission is an independent, not-for-profit organization, which set standards for, and evaluates health care organizations in accordance with nationally recognized guidelines. The standards include an organizations’ level of performance in key functional areas such as: patient rights, patient treatment, infection control, medical staff and environment of care. To earn and maintain accreditation, an organization must undergo an on-site survey by a Joint Commission survey team at least every three years. SASH was last accredited in 2010.
