The original study&#x27;s authors suggest adding a field to death certificates where the hospital personnel would put additional information about the cause of death:<p><i>... death certificates could contain an extra field asking whether a preventable complication stemming from the patient’s medical care contributed to the death.</i><p>How could they do this and, at the same time, shield themselves from lawsuits which use that &quot;extra field&quot; as evidence against them?
