Quality assurance in perinatal and obstetrical care: the Norwegian approach.

OBJECTIVE: To review the structure of all obstetrical units in Norway and to monitor the performance of care in terms of perinatal mortality, ultrasound examination and selected clinical events in routine obstetrical care. METHOD: I. Audit of all perinatal deaths (270) in five Norwegian counties during one year. II. Consensus conference to review the practice and distribution of all antenatal diagnostic ultrasounds performed country-wide over one week. III. Statistical review of quality indicators or flag events in routine obstetrical care. RESULTS: I. Identification of a significant percentage of "avoidable" perinatal deaths, most frequently related to antenatal and neonatal care rather than to obstetrical care--resulting in official guidelines for antenatal care and the routine audit of perinatal deaths. II. 96% of women surveyed had ultrasonography, an average of 2.5 examinations each. An investigational procedure already established practice, it was recommended that one ultrasound performed in week 17-20 should be offered each pregnant woman. III. Clinical obstetrical practice varied significantly and it was noted that junior obstetricians had not adhered to established routines. Short and long term monitoring of clinical trends is considered.

Fetal and maternal aortic flow in two different maternal positions. An investigation with combined Doppler-velocimetry and ultrasonic multiple array.

To study aortic velocities in the fetus, a newly developed multirangegated Doppler velocimeter was combined with a commercial B-mode linear-array apparatus. Spectrum analysis of the Doppler shift signals was performed. The signals with the highest frequencies were selected for hard-copy, and integrated with a digitizer. In the first part of the study, the reproducibility of the method was established by serial measurements of aortic velocity in 7 near-term fetuses. It proved sufficient to evaluate 5 successive heart-cycles. The mean coefficient of variation was 5% (mean number of recordings evaluated 7.5). In the second part of the study, possible influence of aortocaval compression on fetal aortic velocity indicative of changes in fetal cardiac output, was investigated in 10 pregnant women with no symptoms of supine hypotension. Doppler monitoring of the material cardiac output from the suprasternal notch was added to the set-up described to study the supine reduction of cardiac output frequently described in pregnant women. No significant change was found either in the maternal or in the fetal circulation.

Interpersonal conflict and physical abuse in relation to pregnancy and infant birth weight.

Women's experiences of different kinds of abusive behavior by their partners were studied in relation to birth weight of the women's infants and other pregnancy outcome measures. Eighty-four women who delivered a low-birth-weight (< 2500 g) infant (cases) and 90 women who delivered an infant with higher birth weight (controls) were interviewed in a case-control study. Information about the partners' behavior during conflicts were obtained by use of a modified Conflict Tactics Scale. Different interpersonal conflict behaviors were categorized as negative verbal interaction or moderate or severe physical abuse. Women who had experienced moderate or severe violence in a relationship also had experienced negative verbal interaction from their partner. Low birth weight was not associated with experiences of any interpersonal conflict behavior in the total sample (OR 0.75, 95% CI 0.42-1.37). Among women with a low birth weight infant, mean birth weight was 261 g lower among those who reported any interpersonal conflict behavior during pregnancy. Birth of a low-birth-weight infant was not associated with abuse in a wide sense. Also, such abuse was unassociated with a variety of other complications during pregnancy, lifestyle characteristics, or pregnancy outcome measures.
