It short-sighted to look at those reductions in heart attacks and cancer and claim that they are all the result of people not going to the hospital, I'm sure for some percentage is true but there are dozens more factors likely involved: Less going out means less exposure to smog/contamination, less car accidents, less commute-caused stress, less physical confrontations with coworkers and strangers (eg thieves), more homemade food over street food, less bar fights, less weekend nightlife (eg parties) means less likelihood to get a cold (and pneumonia et al), as well as less promiscuity, you get the point, and I'm sure I'm missing a lot more possible factors on this list.
I'm sure there's some truth in all those other factors but I'm not sure how much any of them have to do with heart attack rate, much less cancer.
People are absolutely putting off going to the doctor or hospital for symptoms and problems that they can at least convince themselves are "nothing" or which will get better on their own.
I did it myself in May for a probable pinched nerve. (I did talk to a doctor friend of mine admittedly and she didn't think it was something that needed urgent medical attention and it has largely subsided on its own for now.) But it was definitely at the point where I would normally have gone to see my doctor.
