Objective: Maternal morbidity, either pregnancy related or pre-existent, can become life threatening and of such severity as to warrant termination of pregnancy (TOP). In this situation, chances of fetal survival are usually poor, either because of low gestational age and/or because of the fetal effects of the maternal condition. Examples include severe growth restriction in pre-eclampsia and intrauterine infection due to the very early preterm prelabour rupture of membranes. There are very few reports on the prevalence of TOP for maternal indication at the limits of fetal viability. We investigated the prevalence of and indications for TOP on maternal indication in the 10 tertiary care centres in the Netherlands during the past decade., Study Design: We conducted a retrospective review of the medical records of all women who underwent TOP for maternal indications between 22 and 27 completed weeks of gestation in all 10 tertiary care centres from 2000 to 2009., Results: During the study period, there were 1 929 470 deliveries; 163 052 (8.4%) of these took place in one of the 10 tertiary care centres and 177 pregnancies were terminated for severe maternal disease, 131 for hypertensive disorders, 29 for intrauterine infection and 17 for other reasons. The mean gestational age at TOP was 171 days (24(3/7))±10 days. No maternal deaths were recorded. The overall perinatal mortality was 99.4%., Conclusions: Over a 10-year period, TOP for maternal indications was performed in 1 in 1000 deliveries in the 10 Dutch tertiary care centres. Hypertensive disorders comprised three-quarters of the cases., (Published by the BMJ Publishing Group Limited.

Objective: The central aim of this study was to assess the feasibility of the developed adverse outcome registration method. Furthermore, it was tested whether the information gathered through the registration system allowed for comparative analyses., Design: Prospective observational multicentre study., Setting: The obstetrics and gynaecology departments of three Dutch university and three general hospitals. Population Every consecutive admission to these departments during the 12-month study period., Methods: All complications, during admission and up to 6 weeks after discharge, were registered using a standardised form. The complication type and origin were noted and the severity of the complications were graded., Main Outcome Measures: The differences in relative frequencies of complications between the participating university and general hospitals., Results: A total of 10 470 admissions were observed at the obstetrics and gynaecology departments of the six hospitals combined. The standard complication registration form was completed for approximately 90% of these admissions. A total of 351 gynaecological (9.1%) and 960 obstetrical (14.5%) complications were reported. There was no significant difference in the percentage of complications between general hospitals and university hospitals. The severity of complications, however, varied significantly between the participating hospitals., Conclusions: A feasible framework for complication registration in the field of obstetrics and gynaecology has been developed. Before comparing frequencies of adverse events between hospitals, such outcome measures first need to be risk-adjusted to overcome the problem of patient variation and acuity between hospitals as a source of difference, leaving quality of care as a primary source of variation.
