A cost-benefit analysis of a population screening programme for neural tube defects

Abstract
Population screening for neural tube defects is possible by measuring maternal serum alpha‐fetoprotein levels with appropriate follow‐up as required. British Columbia has approximately 39 000 births annually and the incidence of neural tube defects is 1–55 per 1000 births (0–94 per 1000 livebirths). Results from a cost‐benefit analysis suggest that the outlined screening programme would be cost‐beneficial for British Columbia. Other important factors essential to consider before instituting a population screening programme are discussed.
