Acute Long Term Hospital Association (ALTHA)

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). ALTHA works to protect the rights of medically complex patients and the hospitals that treat them by educating federal and state regulators, members of Congress, and health care industry colleagues. ALTHA also works to increase quality of care by sharing and improving best practices among its hospital members.
