Accuracy of death certificates in neonatal deaths.

Death certificates of neonates were compared with detailed clinical and pathological information provided for a national neonatal mortality survey. The systematic method of assigning the cause of death to one of seven broad categories in the survey found complete agreement with the underlying cause of death on the death certificate in 83 per cent of cases (274/330). There was only a minor disagreement involving clinical opinion in a further 6.7 per cent (22). The reasons for disagreement in the remaining 10.3 per cent (34) were examined. In the majority of instances, 6.0 per cent (20), the fault lay with the certifying doctor who provided inadequate or inaccurate information on the death certificate or who, in providing all the information, appeared to be ignorant of coding rules. In 1.2 per cent (4) the fault lay with coding inaccuracies or misapplication of coding rules in failing to select the underlying cause in a correct sequence of clinical events. In the remaining 3.0 per cent (10) of cases the rules governing the survey did not follow the WHO coding rules.
