My lede:

About one in 50 patients leaves the hospital early, disregarding the doctor’s orders. These patients are three times more likely to be re-hospitalized within a month, according to a recent review of more than two dozen studies since 1970 that examined the phenomenon of “self-discharge.”

Patients who leave early after being admitted for a heart attack are 40% more likely to die or be readmitted with another heart attack or unstable angina in the next two years, said the study in the March Mayo Clinic Proceedings.

The whole shebang.
