We resolved to prescribe folic acid supplements for all women who atte
nded this practice during the first twelve weeks of pregnancy. Six mon
ths after this decision a prescription was recorded in only 13% of cas
es: this compared with 18% during the two months immediately following
the decision. It was resolved to improve this performance and observa
tions six months later revealed a prescription recorded in 63% of case
s. Subsequently a new form for recording an antenatal consultation was
devised and six months after its implementation, 100% recording of fo
late prescription for appropriate cases was observed. It was concluded
that these simple audit exercises prompted changes in practice which
helped to improve standards of patient care.
