Organization formed to protect patient access to quality long-term hospital care; formerly known as Long Term Acute Care Hospital Association of America (LTACHA). Long Term Acute Care Hospitals (LTACHs) are hospitals that provide patients with acute care for extended inpatient stays (defined by federal statute as an average of 25 days or more).
