Not exactly. They wouldn’t be at the hospital if they were perfectly healthy. 
What’s happening is errors in treatment are killing them when whatever was wrong with them wouldn’t have been considered potentially fatal in the first place. Giving wrong medicines, misdiagnosis, inappropriate surgical procedures, exposure to disease pathogens that go unchecked, etc.
I was a senior examiner for the National Quality Award (aka the Baldrige Award) for several years and specialized in the evaluation of hospitals. The really good ones are fanatics about patient outcomes and eliminating errors. There are incredibly detailed and we’ll articulated standards of treatment designed to keep people from getting sick or dying inappropriately due to the care they get in the hospital setting. Hospitals are audited and graded on how they perform and how they respond to failures.
Most hospitals don’t dedicate the resources necessary to be better than good. The really good ones measure in the dozens nationwide.
And yes, 1200 people die everyday from “oops, my bad”.
Henry probably has a lot of stories about the audits and the preventative procedures and the controls. But I bet he isn’t allowed to admit to any life-ending errors.
And a culture that expects risk-free lives.
