|Grading scale used to assess death certificate errors|
|Grade 0||No errors|
|Grade IA||incomplete/inaccurate demographics|
|Grade IB||Whether the signatory attended the patient could not be confirmed|
|Grade II||Co-morbidities list incomplete|
|Grade III||Co-morbidities not listed|
|Grade IV||Inappropriate immediate cause of death or only a mechanism(s) of death (or mode of dying) given *|
|Grade V||Underlying cause(s) of death was incorrectly attributed or placed in an improper sequence|
*Since multiple diseases can cause death by the same mechanism, mechanism of death usually provides little useful information .
