The hospital used to be an acute hospital with accident and emergency service. It was later converted to a chronic hospital to provide extended supportive care to patients from Queen Elizabeth Hospital. The hospital has specialist services in psychiatry, rehabilitation, respiratory medicine and geriatrics. The respiratory medicine unit provides teaching opportunities for medical students from the Li Ka Shing Faculty of Medicine, University of Hong Kong.
With 1,275 beds, the hospital was the first to establish a rehabilitation unit in Hong Kong.
