• Secondary – Acute care services, typically provided by medical personnel, through hospitals, using elaborate diagnostic and treatment procedures.
• Tertiary – Highly technical services, such as for psychiatric and chronic diseases, provided through specialty facilities and teaching hospitals.
• Restorative – Rehabilitative and follow-up acre, typically provided by home health agencies, nursing homes, and halfway houses.
• Continuing – Long-term, chronic care, typically provided by geriatric day care centers and
