Adverse events, negligence in hospitalized patients: results from the Harvard Medical Practice Study

Perspect Healthc Risk Manage. 1991 Spring;11(2):2-8. doi: 10.1002/jhrm.5600110202.


In summary, we reviewed a random sample of 30,000 medical records from New York State in 1984, analyzing them for the presence of adverse events and substandard care. We believe that our findings indicate that there are certain risk factors, many definable, for the occurrence of adverse events and negligence.
