The contribution of developmental surveillance to early detection of cerebral palsy.

A retrospective study of the contribution of examinations at Child Health Centres (CHC) for early detection of cerebral palsy (CP) was performed in 23,924 children, born in 1986-90, in the south-western part of Stockholm County. The outcome assessed was age of referral to a habilitation unit. A total of 66 children with CP (2.76/1000) were identified through the register at the responsible habilitation unit. The age of referral was, median 8 months, mean 12.4 months and range 0.5-54 months. A peak of referrals at 8-9 months was produced by CHC checks at 6 months of age. No other examination at the CHC resulted in a significant number of referrals. Nineteen records from CHC concerning moderate and severe cases were reviewed. Out of all examinations with aberrant findings only 11/20 resulted in referrals or further examinations. No child with moderate or severe CP was referred due to developmental screening test findings only.
