Their EMR is a major reason. Although I don’t think it works this well:

Most private hospitals can only dream of the futuristic medicine Dr. Divya Shroff practices today. Outside an elderly patient’s room, the attending physician gathers her residents around a wireless laptop propped on a mobile cart. Shroff accesses the patient’s entire medical history–a stack of paper in most private hospitals. And instead of trekking to the radiology lab to view the latest X-ray, she brings it up on her computer screen. While Shroff is visiting the patient, a resident types in a request for pain medication, then punches the SEND button. Seconds later, the printer in the hospital pharmacy spits out the order. The druggist stuffs a plastic bag of pills into what looks like a tiny space capsule, then shoots it up to the ward in a vacuum tube. By the time Shroff wheels away her computer, a nurse walks up with the drugs.
