This may be both due a data quality issue or practice change. The incidence of cord pH less than 7.00 recorded as 0 is probably a data quality issue. The incidence of caesarean section at VE =10 at 0.9% is a little low and may be a data quality issue as is admissions to the neonatal unit which has been lower this year.
