Prevention of unexpected infant death. A review of risk-related intervention in six centers.

Over seventy percent of unexpected infant deaths are registered as SIDS. Over 85,000 infants have been screened at birth and one month of age for risk of unexpected death using the Sheffield Score system. Scores range from below 400 to over 800 points. Infants with scores over 800 are at more than 16 times greater risk than infants with scores below 400. Family doctors and health visitors were alerted to high-risk infants, who were examined at home and weighed naked at home five times in the first six months. Mortality in the high-risk group was reduced by more than 50% (p less than 0.02 in one area and p less than 0.05 in another). It is concluded that with few extra resources unexpected infant mortality can be reduced by 25% by this approach.
