Blair E, et al. - Using survival analysis method, researchers characterized survival and mortality trends up to the sixth century in a geographically defined population of individuals with stratified cerebral palsy (CP) based on the clinical description of their early childhood impairments. Of the 3185 eligible individuals, 436 (13.7%) died. For 22% of the CP population with the mildest impairments, the length of survival to 58 years does not differ significantly from that of the population, but with increasingly severe impairments, as expected, the standardised mortality ratio increases. However, over 80% have a life expectancy beyond 58 years and longer follow-up of population-based samples with detailed descriptions of impairments is suggested in order to obtain a more complete picture of CP survival. Mortality has tended to change from infancy to early adulthood for those with severe CP in Western Australia since 1990.
