Overview :
The
Sheffield Birth Score was developed by the Sheffield Intervention Programme,
which was intended to reduce the risk of unexpected infant death. This can be
used to identify neonates at increased risk of unexpected death during the first
year of life, so that interventions can be made to reduce the risk.
Parameters
(for the revised score II from 1977):
(1)
maternal age
(2) number
of previous pregnancies
(3)
duration of second stage of labor
(4)
maternal ABO blood type
(5)
birthweight in grams
(6) twin
status
(7) feeding
intentions
(8) urinary
tract infection during pregnancy

•
handling of maternal age > 50 is not mentioned
•
the number of previous pregnancies does not appear to be limited to
livebirths
•
if twins born, each would be assessed separately
•
handling of multiple births other
than twins is not mentioned
