Table: DETH
Short description: Wigglesworth code. Death of LS member (1993 onwards).
Full description: This field is a code that indicates the degree of severity involved in a Neonatal death (death at 27 days or under) based on the ICD codes identified for that death. Since the new death certificate was introduced in January 1986, making information available about both the child's and mother's condition, it has been more problematic to derive a single underlying cause, based on the assumption of a chain of events leading to the death. This variable is derived by an algorithm based on the work of Jonathan Wigglesworth which uses a hierarchical procedure to atttempt to find the most accurate way of categorising the underlying cause.
Coding notes: 1993 onwards:
1=Congenital Malformation or Defect
2=Antepartum Infection
3=Immaturity related conditions
4=Asphyxia, Anoxia or Trauma
5=External Conditions
7=Other Specific Conditions
8=(Not applicable for Neonates)
9=Sudden Infant Death Syndrome (SIDS)
