Assessment of the effect upon maternal knowledge of an information leaflet about pain relief in labour

Pregnant women were randomly assigned to receive, at booking, the usual written information pack either with or without the Obstetric Anaesthetists' Association's (OAA's) leaflet 'Pain Relief in Labour'. At 36 weeks' gestation, a structured interview was conducted at which we assessed the sources of information the women had used and their knowledge of specific aspects of obstetric analgesia and anaesthesia described in the OAA leaflet. The most useful sources of information overall were friends, family, midwives, books and information leaflets (no significant difference between the groups); 72% of all women felt they had received adequate information although 70% said they would have liked to have discussed methods of analgesia with an anaesthetist before delivery. Parturients allocated to receive the leaflet (n = 37) were more knowledgeable than those who received only standard booking information (n = 39) about all analgesic and anaesthetic techniques except for systemic pethidine, although this difference in knowledge only reached statistical significance for extending epidural analgesia for emergency Caesarean section. We conclude that the OAA leaflet improves women's knowledge of analgesic techniques and suggest that all information of this type be formally assessed in this manner; furthermore given the practical difficulties in conducting studies of this type, the latter should be adequately resourced, perhaps by the bodies that issue such leaflets.
