Definition and Scope

Acute care encompasses a range of clinical health-care functions, including:

• Emergency medicine: Immediate treatment for sudden and severe illnesses or injuries.
• Trauma care: Specialized medical services for patients suffering from traumatic injuries.
• Critical care: Intensive care provided to patients with life-threatening conditions requiring comprehensive monitoring and support.
• Urgent care: Immediate outpatient services for conditions that require prompt attention but are not life-threatening.
• Short-term inpatient stabilization: Hospitalization for brief periods to stabilize acute medical conditions before transitioning to other levels of care.

Settings for Acute Care

Acute care services are typically provided in various healthcare settings, including:

• Hospitals: Facilities equipped with emergency departments, intensive care units, and specialized medical and surgical services.
• Ambulatory surgery centers: Outpatient facilities where surgeries not requiring prolonged hospital stays are performed.
