Something to ease our hospitals?

I was recently reading an article on relieving the overcrowded hospitals by giving elderly an alternative to hospitals. The solution was to allow certain specialist healthcare at home. The person, also a doctor, detailed an experience of an elderly in a hospital:

I called an ambulance and admitted him to the hospital, where we soon brought his urinary tract infection under control. But he developed a bedsore, which became infected with an antibiotic-resistant bacterium that bred in hospitals. He didn't survive the hospitalisation.

Do we always need to be hospitalised? Can we recuperate at home instead of in a hospital? Most important of all, is it cheaper to provide specialist healthcare at our own home, or to find the land to build a new hospital, especially in land-scarce places like Singapore?

Something to think about...
