Hospital admissions have become less and less over time. Most medical care can be done on an ambulatory set-up, or so-called daycare setting. In fact, many conditions can now be managed remotely wherever you are.
Being ambulatory roughly equates to moving around. Hence ambulatory care revolves around outpatient services, with hardly any need for hospital admission. At its most basic, you get yourself to a medical facility, have all your interventions done during the day, then head back home. Many medical conditions, ranging from emergencies to chronic conditions, easily render themselves to appropriate management in an ambulatory set-up.
