Under which type of health care services should subacute care be included?

• A. Quaternary care
• B. Primary care
• C. Secondary care
• D. Tertiary care (correct)

Answer: (D)

Subacute care sits in the post-acute phase, where patients no longer need full acute hospital care but still require substantial monitoring, rehabilitation, and complex medical management. This level of care involves a multidisciplinary team, advanced therapies, and specialized procedures that go beyond routine primary care or general inpatient treatment.

Why this fits tertiary care: tertiary care encompasses highly specialized, complex services and facilities that manage advanced medical conditions and rehabilitation needs. Subacute units—whether inside a hospital or in a dedicated post-acute facility linked to a tertiary center—provide stabilization, intensive rehabilitation, wound care, IV therapy, and coordinated care for patients transitioning from acute illness or surgery. These needs exceed what primary care or standard secondary care typically offers, but they are not the full, emergency-intensive care of the initial hospitalization. Therefore, subacute care is best categorized under tertiary care.

In contrast, primary care focuses on first-contact, routine, preventive, and ongoing health maintenance; secondary care covers more specialized inpatient or outpatient services for specific conditions but at a level below the highly specialized, complex management seen in subacute settings; quaternary care refers to even more specialized or experimental interventions beyond typical tertiary needs.
