How good is ultrasound in the detection and evaluation of anterior abdominal wall defects?

The ability of routine obstetric ultrasound to detect and accurately describe fetuses with anterior abdominal wall defects has been examined in an unselected population using data from a regional abnormality survey. Examination between 16 and 22 weeks gestation detected 60% of defects with a false positive rate of 5.3%. Fetuses with gastroschisis were incorrectly assigned as exomphalos in 14.7% of cases recognized before 22 weeks gestation. The diagnosis, including description of associated detectable anomalies, was completely accurate in 71.6% of cases. Some of the problems of diagnostic accuracy need to be considered when counselling couples with a fetal anomaly. Cross-referral between obstetric ultrasound units should be encouraged to improve diagnostic accuracy. These results form the basis for audit of obstetric ultrasound in the diagnosis of fetal abnormality within a geographically defined population.

Northern Region Fetal Abnormality Survey results 1987.

The UK Northern Region Fetal Abnormality Survey was notified of 572 suspected fetal abnormalities in 1987. Of these, 265 (46%) had pediatric surgical implications. Because the registry traces the postnatal outcome of each notification and records congenital abnormalities diagnosed postnatally, it is possible to measure both sensitivity and selectivity of antenatal diagnosis of fetal abnormalities. Cases were divided into five groups: diaphragmatic hernia, abdominal wall defects, intestinal anomalies, neural tube defects, and urological anomalies. Each group comprised cases that were unsuspected, suspected but not confirmed, and suspected and confirmed. Sensitivity was highest in the urological group, but 30% of the notified cases were unconfirmed so selectivity was higher in the abdominal wall and neural tube groups. None of the diaphragmatic hernias and only 14.3% of the intestinal anomalies were correctly suspected. Only 13.5% of all neural tube defects were treated surgically. The Survey has improved cooperation and communication between specialists concerned with the management of fetal abnormalities and this in turn has improved patient care.

Quality assurance in Australian hospitals: who does it and how?

OBJECTIVE: To seek information on the type, method and extent of quality assurance being undertaken in all public and private hospitals within Australia. METHOD: Mailed questionnaire. RESULTS: There was a predominance of two types of review being undertaken. Some important deficiencies in the quality assurance process were identified. Far more private than public hospitals reviewed medical records and surveyed patient satisfaction.
