It is extremely ill or injured elders who need Critical care nursing services. Depending on the condition, the doctors decide whether the patient needs critical care services or not. It can be a stroke, cardiac arrest, cancer, or some neurology condition. And if the elder does need these services, the doctors check if they can be available at the elder’s home. At-home critical care services are usually the choice after the patient has received some intensive care at the ICU in the hospital. But further staying in the hospital can be problematic for the elder. Sometimes there are financial issues. Other times it is stress issues or even infections at the hospital that may need the elder's treatment to happen at their home.
