Antenatal prediction of urinary tract infection in pregnancy.

Prediction of urinary tract infection in pregnancy by bacteriuria testing is unsatisfactory; if resources are short, the taking of a careful history of previous urinary tract infection is almost as effective. Restriction of bacteriuria testing to the women with such a history would be more economical than routine testing and would give better specificity (but not sensitivity) than bacteriuria testing or history taking alone.

An audit of antenatal care: the value of the first antenatal visit.

A critical analysis of the events recorded at the first antenatal visits in a city where all pregnant women are seen by specialist obstetricians for booking for antenatal care and confinement showed that many women attended too late for optimal care. The selection of women for their risk of complications was not very effective, partly because of failure to take account of information that was available, but mainly because many obstetric complications cannot be predicted, except by classifying large proportions of pregnant women as high risk. Even with the greatest care, inappropriate bookings are made at the first visit, and reappraisal of booking for continuing care and confinement is necessary during pregnancy.

Is routine antenatal care worth while?

An analysis of the rate at which asymptomatic problems are diagnosed, missed, and overdiagnosed in a total population of pregnant women attending specialists and general practitioners for antenatal care indicated that detection of some problems is incomplete and that overdiagnosis is common. The productivity of routine antenatal care in respect of prediction and detection of obstetric problems is extremely low, and it is suggested that the number of visits for this purpose could be considerably reduced for women without special problems.
