Neonatal Mortality Clusters: A New Tool For Classifying Neonatal Outcomes

Abstract

Background: A method for assessing general hospital neonatal care performance is needed that is simple, is easy to use, and requires minimal data.

Methods: All neonatal deaths in Washington State obstetric hospitals from 1980 to 1983 were assigned to 10 mutually exclusive neonatal mortality clusters, a new classification method derived from information available on the death certificate.

Results: More than one-third (35.3 percent) of all neonatal deaths fell within one of the seven clusters considered to represent potentially preventable causes of death. The rate of possibly preventable deaths was much higher in level III hospitals than in level II or level I hospitals, a finding similar to that observed in other states using different analytic approaches.

Conclusions: Neonatal mortality clusters offer a less complex method of classifying neonatal deaths and assessing hospital performance than other currently used techniques.
