Evaluating Adherence to Guideline-Based Quality Indicators for Postpartum Hemorrhage Care in the Netherlands Using Video Analysis.

OBJECTIVE: To assess adherence to the national postpartum hemorrhage guideline and Managing Obstetric Emergencies and Trauma course instructions and its determinants in the Netherlands. METHODS: A prospective observational multicenter study in 16 Dutch hospitals analyzing data from medical records of 398 women at high risk for postpartum hemorrhage, of which 293 were supplemented with data from prospective video recordings. Adherence to guideline-based quality indicators for prevention, management, and organization of postpartum hemorrhage care was measured. Indicators for prevention and management of postpartum hemorrhage were categorized according to the amount of blood loss (less than 500, greater than 500, greater than 1,000, and greater than 2,000 mL). RESULTS: Overall, a lack of adherence was observed, particularly for the actions to be undertaken with blood loss greater than 1,000 mL (69 patients). Actions were not or only taken in a later stage when the blood loss had already increased to greater than 2,000 mL (21 patients). In almost 41% (n=119/293) of the deliveries, no active management was performed, and in almost 80% (n=89/112), vital signs were not monitored (blood loss greater than 500 mL) or monitored too late with respect to blood loss. The video recordings showed that in general the actual care given was considerably underreported in medical records. Postpartum hemorrhage care in the hospitals was well organized. Fifteen hospitals had a local postpartum hemorrhage protocol, and in 12 hospitals, team trainings were organized. Regarding the determinants, high-risk patient identification and type of hospital (university vs nonuniversity hospital) were mostly associated with better adherence. CONCLUSION: This study showed low adherence to the guideline-based quality indicators, indicating a problem with Dutch quality care. The unique video observations provided additional, valuable information at which level improvement can be made. A tailor-made implementation strategy to improve quality of postpartum hemorrhage care has been developed. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT00928863.

Pessary or Progesterone to Prevent Preterm delivery in women with short cervical length: the Quadruple P randomised controlled trial.

BACKGROUND: Preterm birth is in quantity and in severity the most important topic in obstetric care in the developed world. Progestogens and cervical pessaries have been studied as potential preventive treatments with conflicting results. So far, no study has compared both treatments. METHODS/DESIGN: The Quadruple P study aims to compare the efficacy of vaginal progesterone and cervical pessary in the prevention of adverse perinatal outcome associated with preterm birth in asymptomatic women with a short cervix, in singleton and multiple pregnancies separately. It is a nationwide open-label multicentre randomized clinical trial (RCT) with a superiority design and will be accompanied by an economic analysis. Pregnant women undergoing the routine anomaly scan will be offered cervical length measurement between 18 and 22 weeks in a singleton and at 16-22 weeks in a multiple pregnancy. Women with a short cervix, defined as less than, or equal to 35 mm in a singleton and less than 38 mm in a multiple pregnancy, will be invited to participate in the study. Eligible women will be randomly allocated to receive either progesterone or a cervical pessary. Following randomization, the silicone cervical pessary will be placed during vaginal examination or 200 mg progesterone capsules will be daily self-administered vaginally. Both interventions will be continued until 36 weeks gestation or until delivery, whichever comes first. Primary outcome will be composite adverse perinatal outcome of perinatal mortality and perinatal morbidity including bronchopulmonary dysplasia, intraventricular haemorrhage grade III and IV, periventricular leukomalacia higher than grade I, necrotizing enterocolitis higher than stage I, Retinopathy of prematurity (ROP) or culture proven sepsis. These outcomes will be measured up until 10 weeks after the expected due date. Secondary outcomes will be, among others, time to delivery, preterm birth rate before 28, 32, 34 and 37 weeks, admission to neonatal intensive care unit, maternal morbidity, maternal admission days for threatened preterm labour and costs. DISCUSSION: This trial will provide evidence on whether vaginal progesterone or a cervical pessary is more effective in decreasing adverse perinatal outcome in both singletons and multiples.

Patient controlled analgesia with remifentanil versus epidural analgesia in labour: randomised multicentre equivalence trial.

OBJECTIVE: To determine women's satisfaction with pain relief using patient controlled analgesia with remifentanil compared with epidural analgesia during labour. DESIGN: Multicentre randomised controlled equivalence trial. SETTING: 15 hospitals in the Netherlands. PARTICIPANTS: Women with an intermediate to high obstetric risk with an intention to deliver vaginally. To exclude a clinically relevant difference in satisfaction with pain relief of more than 10%, we needed to include 1136 women. Because of missing values for satisfaction this number was increased to 1400 before any analysis. We used multiple imputation to correct for missing data. INTERVENTION: Before the onset of active labour consenting women were randomised to a pain relief strategy with patient controlled remifentanil or epidural analgesia if they requested pain relief during labour. MAIN OUTCOME MEASURES: Primary outcome was satisfaction with pain relief, measured hourly on a visual analogue scale and expressed as area under the curve (AUC), thus providing a time weighted measure of total satisfaction with pain relief. A higher AUC represents higher satisfaction with pain relief. Secondary outcomes were pain intensity scores, mode of delivery, and maternal and neonatal outcomes. Analysis was done by intention to treat. The study was defined as an equivalence study for the primary outcome. RESULTS: 1414 women were randomised, of whom 709 were allocated to patient controlled remifentanil and 705 to epidural analgesia. Baseline characteristics were comparable. Pain relief was ultimately used in 65% (447/687) in the remifentanil group and 52% (347/671) in the epidural analgesia group (relative risk 1.32, 95% confidence interval 1.18 to 1.48). Cross over occurred in 7% (45/687) and 8% (51/671) of women, respectively. Of women primarily treated with remifentanil, 13% (53/402) converted to epidural analgesia, while in women primarily treated with epidural analgesia 1% (3/296) converted to remifentanil. The area under the curve for total satisfaction with pain relief was 30.9 in the remifentanil group versus 33.7 in the epidural analgesia group (mean difference -2.8, 95% confidence interval -6.9 to 1.3). For who actually received pain relief the area under the curve for satisfaction with pain relief after the start of pain relief was 25.6 in the remifentanil group versus 36.1 in the epidural analgesia group (mean difference -10.4, -13.9 to -7.0). The rate of caesarean section was 15% in both groups. Oxygen saturation was significantly lower (SpO2 <92%) in women who used remifentanil (relative risk 1.5, 1.4 to 1.7). Maternal and neonatal outcomes were comparable between both groups. CONCLUSION: In women in labour, patient controlled analgesia with remifentanil is not equivalent to epidural analgesia with respect to scores on satisfaction with pain relief. Satisfaction with pain relief was significantly higher in women who were allocated to and received epidural analgesia. TRIAL REGISTRATION: Netherlands Trial Register NTR2551.

Foley catheter or prostaglandin E2 inserts for induction of labour at term: an open-label randomized controlled trial (PROBAAT-P trial) and systematic review of literature.

OBJECTIVE: To assess the safety and effectiveness of a transcervical Foley catheter compared to vaginal prostaglandin E2 inserts for term induction of labour. STUDY DESIGN: We conducted an open-label randomized controlled trial in five hospitals in the Netherlands. Women with a singleton term pregnancy in cephalic presentation, intact membranes, unfavourable cervix, and no prior caesarean section were enrolled. Participants were randomly allocated by a web-based randomization system to induction of labour with a 30 ml Foley catheter or 10mg slow-release vaginal prostaglandin E2 inserts in a 1:1 ratio. Due to the nature of the intervention this study was not blinded. The primary outcome was the caesarean section rate. Secondary outcomes were maternal and neonatal morbidity and time from intervention to birth. Additionally, we carried out a systematic review and meta-analysis of similar studies. RESULTS: We analyzed 226 women: 107 received a Foley catheter and 119 inserts. Caesarean section rates were comparable (20% versus 22%, RR 0.90, 95% CI 0.54-1.50). Secondary outcomes showed no differences. We observed no serious maternal or neonatal morbidity. Meta-analysis showed comparable caesarean section rates, but significantly fewer cases of hyperstimulation during the ripening phase when a Foley catheter was used. CONCLUSIONS: We found, in this relatively small study, no differences in effectiveness and safety of induction of labour with a Foley catheter and 10mg slow release vaginal prostaglandin E2 inserts. Meta-analysis confirmed a comparable caesarean section rate, and showed fewer cases of hyperstimulation when a Foley catheter was used.

[Group counselling for the second trimester ultrasound: can group counselling be an alternative for individual counselling?]. / Counseling bij het structureel echoscopisch onderzoek: is groepscounseling een alternatief voor individuele counseling?

OBJECTIVE: To compare group counselling to individual counselling with respect to the second trimester ultrasound. DESIGN: A prospective cohort study at two hospitals. METHOD: At one hospital, 100 pregnant women were counselled on the risks and benefits of the second trimester ultrasound in groups of up to 15 patients. Shortly before the ultrasound they were asked to fill out a questionnaire. Results were compared to 100 women who were counselled individually at another hospital. The primary outcome was the level of informed choice whether or not to undergo the ultrasound, defined as sufficient knowledge and a value-consistent decision. The secondary outcome measures were level of understanding of the second trimester ultrasound and the degree of satisfaction with the counselling. RESULTS: The resulting level of informed choice was 87.0% after group counselling compared to 79.4% after individual counselling (p = 0.47). The mean knowledge score was 8.8 for the women who attended group counselling; women who were individually counselled had a mean score of 7.4 (p < 0.001). Satisfaction with counselling was 7.0 for group counselling and 6.2 for individual counselling (p < 0.001). CONCLUSION: Although there was no statistically significant difference in the level of informed choice, group counselling was associated with higher post-counselling knowledge and satisfaction scores. Group counselling should therefore be considered as an alternative counselling method.

Remifentanil patient controlled analgesia versus epidural analgesia in labour. A multicentre randomized controlled trial.

BACKGROUND: Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. METHODS/DESIGN: The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia.Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief.Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity), mode of delivery and maternal and neonatal side effects.The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. DISCUSSION: This study, considering cost effectiveness of remifentanil as first choice analgesia versus epidural analgesia, could strongly improve the care for 180.000 women, giving birth in the Netherlands yearly by giving them access to pain relief during labour, 24 hours a day.

Identification of cases with adverse neonatal outcome monitored by cardiotocography versus ST analysis: secondary analysis of a randomized trial.

OBJECTIVE: To evaluate whether correct adherence to clinical guidelines might have led to prevention of cases with adverse neonatal outcome. DESIGN: Secondary analysis of cases with adverse outcome in a multicenter randomized clinical trial. SETTING: Nine Dutch hospitals. POPULATION: Pregnant women with a term singleton fetus in cephalic position. METHODS: Data were obtained from a randomized trial that compared monitoring by STAN® (index group) with cardiotocography (control group). In both trial arms, three observers independently assessed the fetal surveillance results in all cases with adverse neonatal outcome, to determine whether an indication for intervention was present, based on current clinical guidelines. MAIN OUTCOME MEASURES: Adverse neonatal outcome cases fulfilled one or more of the following criteria: (i) metabolic acidosis in umbilical cord artery (pH < 7.05 and base deficit in extracellular fluid >12 mmol/L); (ii) umbilical cord artery pH < 7.00; (iii) perinatal death; and/or (iv) signs of moderate or severe hypoxic ischemic encephalopathy. RESULTS: We studied 5681 women, of whom 61 (1.1%) had an adverse outcome (26 index; 35 control). In these women, the number of performed operative deliveries for fetal distress was 18 (69.2%) and 16 (45.7%), respectively. Reassessment of all 61 cases showed that there was a fetal indication to intervene in 23 (88.5%) and 19 (57.6%) cases, respectively. In 13 (50.0%) vs. 11 (33.3%) cases, respectively, this indication occurred more than 20 min before the time of delivery, meaning that these adverse outcomes could possibly have been prevented. CONCLUSIONS: In our trial, more strict adherence to clinical guidelines could have led to additional identification and prevention of adverse outcome.

Mode of delivery in non-cephalic presenting twins: a systematic review.

PURPOSE: This systematic review aims to determine if there are evidence-based recommendations for the optimal mode of delivery for non-cephalic presenting first- and/or second twins. We investigated the impact of the mode of delivery on neonatal outcome for twin deliveries with (1) the first twin (twin A) in non-cephalic presentation, (2) the second (twin B) in non-cephalic presentation and (3) both twins in non-cephalic presentation. METHODS: A computer-aided search of Medline, Embase, Cinahl and Cochrane databases was carried out and quality of the studies was assessed with the Cochrane Collaboration's tool for assessing risk of bias and the GRADE approach. RESULTS: One high-quality clinical trial (60 twin pairs) and 16 moderate/low-quality observational studies (3,167 twin pairs) showed no difference in neonatal outcome between vaginal and caesarean delivery in twin A and/or B. CONCLUSION: Our results do not suggest benefit of caesarean over vaginal delivery for selected twin gestations with twin A and/or twin B in non-cephalic presentation. However, no final conclusion can be drawn due to the small sample sizes and statistic limitations of the included studies. Randomized studies with sufficient power are required to make a strong recommendation.

Prediction of neonatal metabolic acidosis in women with a singleton term pregnancy in cephalic presentation.

We sought to predict neonatal metabolic acidosis at birth using antepartum obstetric characteristics (model 1) and additional characteristics available during labor (model 2). In 5667 laboring women from a multicenter randomized trial that had a high-risk singleton pregnancy in cephalic presentation beyond 36 weeks of gestation, we predicted neonatal metabolic acidosis. Based on literature and clinical reasoning, we selected both antepartum characteristics and characteristics that became available during labor. After univariable analyses, the predictors of the multivariable models were identified by backward stepwise selection in a logistic regression analysis. Model performance was assessed by discrimination and calibration. To correct for potential overfitting, we (internally) validated the models with bootstrapping techniques. Of 5667 neonates born alive, 107 (1.9%) had metabolic acidosis. Antepartum predictors of metabolic acidosis were gestational age, nulliparity, previous cesarean delivery, and maternal diabetes. Additional intrapartum predictors were spontaneous onset of labor and meconium-stained amniotic fluid. Calibration and discrimination were acceptable for both models (c-statistic 0.64 and 0.66, respectively). In women with a high-risk singleton term pregnancy in cephalic presentation, we identified antepartum and intrapartum factors that predict neonatal metabolic acidosis at birth.

Predictive value of the baseline T-QRS ratio of the fetal electrocardiogram in intrapartum fetal monitoring: a prospective cohort study.

OBJECTIVE: To evaluate the added value of the baseline T/QRS ratio to other known risk factors in predicting adverse outcome and interventions for suspected fetal distress. DESIGN: Prospective cohort study. SETTING: Three academic and six non-academic teaching hospitals in the Netherlands. POPULATION: Laboring women with a high-risk cephalic singleton pregnancy beyond 36 weeks of gestation. METHODS: We obtained STAN(®) recordings (ST-analysis, Neoventa, Sweden) from two previous studies. Three patient groups were defined: cases with adverse outcome, cases with emergency delivery because of suspected fetal distress without adverse outcome, and a reference group of uncomplicated cases. Baseline T/QRS ratios among the adverse outcome and intervention for suspected fetal distress cases were compared to those of the uncomplicated cases. The ability of baseline T/QRS to predict adverse outcome and suspected fetal distress was determined using a multivariable logistic model. MAIN OUTCOME MEASURES: The added value of the baseline T/QRS to other known risk factors in the prediction of adverse outcome and interventions for suspected fetal distress. RESULTS: From 3462 recordings, 2459 were available for analysis. Median baseline T/QRS for uncomplicated cases, adverse outcome and interventions for suspected fetal distress were 0.12 (range 0.00-0.52), 0.12 (0.00-0.42) and 0.13 (0.00-0.39), respectively. There was no statistical difference between these groups. Multivariable analysis showed no added value of baseline T/QRS in the prediction of either adverse outcome or interventions for suspected fetal distress. CONCLUSION: Baseline T/QRS has no added value in the prediction of adverse neonatal outcome or interventions for suspected fetal distress.

Risk of uterine rupture in women undergoing trial of labour with a history of both a caesarean section and a vaginal delivery.

PURPOSE: To determine the risk of uterine rupture for women undergoing trial of labour (TOL) with both a prior caesarean section (CS) and a vaginal delivery. METHODS: A systematic literature search was performed using keywords for CS and uterine rupture. The results were critically appraised and the data from relevant and valid articles were extracted. Odds ratios were calculated and a pooled estimate was determined using the Mantel-Haenszel method. RESULTS: Five studies were used for final analysis. Three studies showed a significant risk reduction for women with both a previous CS and a prior vaginal delivery (PVD) compared to women with a previous CS only, and two studies showed a trend towards risk reduction. The absolute risk of uterine rupture with a prior vaginal delivery varied from 0.17 to 0.46%. The overall odds ratio for PVD was 0.39 (95% CI 0.29-0.52, P < 0.00001). CONCLUSION: Women with a history of both a CS and vaginal delivery are at decreased risk of uterine rupture when undergoing TOL compared with women who have only had a CS.

Cerebrospinal fluid leakage, an uncommon complication of fetal blood sampling: a case report and review of the literature.

UNLABELLED: In a recently published randomized clinical trial on intrapartum fetal monitoring, fetal blood samples were obtained in 879 women. One serious complication of fetal blood sampling (FBS) was reported, a case in which physical examination of the neonate after delivery revealed clear fluid loss from the incision site. Four layers of the scalp appeared to be incised. The subarachnoid space was closed with 2 sutures, and antibiotics were started due to the risk of meningitis. The patient was discharged in good clinical condition. In this article, the case is presented and the literature reviewed. We found 12 articles reporting 37 cases of a complication due to FBS, none concerning leakage of cerebrospinal fluid. In conclusion, complications of FBS are rare but can be serious. Excessive fetal bleeding is most frequently reported and often associated with an underlying coagulopathy in the neonate. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES: After completion of this educational activity, the obstetrician/gynecologist should be better able to assess the chance of possible complications due to fetal blood sampling; select fetuses at risk for complications due to fetal blood sampling; and evaluate certain technical precautions when performing this procedure.

Cost-effectiveness of cardiotocography plus ST analysis of the fetal electrocardiogram compared with cardiotocography only.

OBJECTIVE: To assess the cost-effectiveness of addition of ST analysis of the fetal electrocardiogram (ECG; STAN) to cardiotocography (CTG) for fetal surveillance during labor compared with CTG only. DESIGN: Cost-effectiveness analysis based on a randomized clinical trial on ST analysis of the fetal ECG. SETTING: Obstetric departments of three academic and six general hospitals in The Netherlands. Population. Laboring women with a singleton high-risk pregnancy, a fetus in cephalic presentation, a gestational age >36 weeks and an indication for internal electronic fetal monitoring. METHODS: A trial-based cost-effectiveness analysis was performed from a health-care provider perspective. MAIN OUTCOME MEASURES: Primary health outcome was the incidence of metabolic acidosis measured in the umbilical artery. Direct medical costs were estimated from start of labor to childbirth. Cost-effectiveness was expressed as costs to prevent one case of metabolic acidosis. RESULTS: The incidence of metabolic acidosis was 0.7% in the ST-analysis group and 1.0% in the CTG-only group (relative risk 0.70; 95% confidence interval 0.38-1.28). Per delivery, the mean costs per patient of CTG plus ST analysis (n= 2 827) were €1,345 vs. €1,316 for CTG only (n= 2 840), with a mean difference of €29 (95% confidence interval -€9 to €77) until childbirth. The incremental costs of ST analysis to prevent one case of metabolic acidosis were €9 667. CONCLUSIONS: The additional costs of monitoring by ST analysis of the fetal ECG are very limited when compared with monitoring by CTG only and very low compared with the total costs of delivery.

Well being of obstetric patients on minimal blood transfusions (WOMB trial).

BACKGROUND: Primary postpartum haemorrhage is an obstetrical emergency often causing acute anaemia that may require immediate red blood cell (RBC) transfusion. This anaemia results in symptoms such as fatigue, which may have major impact on the health-related quality of life. RBC transfusion is generally thought to alleviate these undesirable effects although it may cause transfusion reactions. Moreover, the postpartum haemoglobin level seems to influence fatigue only for a short period of time. At present, there are no strict transfusion criteria for this specific indication, resulting in a wide variation in postpartum policy of RBC transfusion in the Netherlands. METHODS/DESIGN: The WOMB trial is a multicentre randomised non-inferiority trial. Women with acute anaemia due to postpartum haemorrhage, 12-24 hours after delivery and not initially treated with RBC transfusion, are eligible for randomisation. Patients with severe physical complaints are excluded. Patients are randomised for either RBC transfusion or expectant management. Health related quality of life (HRQoL) will be assessed at inclusion, at three days and one, three and six weeks postpartum with three validated measures (Multi-dimensional Fatigue Inventory, ShortForm-36, EuroQol-5D). Primary outcome of the study is physical fatigue three days postpartum. Secondary outcome measures are general and mental fatigue scores and generic health related quality of life scores, the number of RBC transfusions, length of hospital stay, complications and health-care costs. The primary analysis will be by intention-to-treat. The various longitudinal scores will be evaluated using Repeated Measurements ANOVA. A costs benefit analysis will also be performed. The power calculation is based on the exclusion of a difference in means of 1.3 points or greater in favour of RBC transfusion arm regarding physical fatigue subscale. With missing data not exceeding 20%, 250 patients per arm have to be randomised (one-sided alpha = 0.025, power = 80%). DISCUSSION: This study will provide evidence for a guideline regarding RBC transfusion in the postpartum patient suffering from acute anaemia. Equivalence in fatigue score, remaining HRQoL scores and physical complications between both groups is assumed, in which case an expectant management would be preferred to minimise transfusion reactions and costs.

Cardiotocography plus ST analysis of fetal electrocardiogram compared with cardiotocography only for intrapartum monitoring: a randomized controlled trial.

OBJECTIVE: To estimate the effectiveness of intrapartum fetal monitoring by cardiotocography plus ST analysis using a strict protocol for performance of fetal blood sampling. METHODS: We performed a multicenter randomized trial among laboring women with a high-risk singleton pregnancy in cephalic presentation beyond 36 weeks of gestation. Participants were assigned to monitoring by cardiotocography with ST analysis (index) or cardiotocography only (control). Primary outcome was metabolic acidosis, defined as an umbilical cord artery pH below 7.05 combined with a base deficit calculated in the extracellular fluid compartment above 12 mmol/L. Secondary outcomes were metabolic acidosis in blood, operative deliveries, Apgar scores, neonatal admissions, and hypoxic-ischemic encephalopathy. RESULTS: We randomly assigned 5,681 women to the two groups (2,832 index, 2,849 control). The fetal blood sampling rate was 10.6% in the index compared with 20.4% in the control group (relative risk 0.52; 95% [CI] 0.46-0.59). The primary outcome occurred 0.7% in the index compared with 1.1% in the control group (relative risk 0.70; 95% CI 0.38-1.28; number needed to treat 252). Using metabolic acidosis calculated in blood, these rates were 1.6% and 2.6%, respectively (relative risk 0.63; 95% CI 0.42-0.94; number needed to treat 100). The number of operative deliveries, low Apgar scores, neonatal admissions, and newborns with hypoxic-ischemic encephalopathy was comparable in both groups. CONCLUSION: Intrapartum monitoring by cardiotocography combined with ST analysis does not significantly reduce the incidence of metabolic acidosis calculated in the extracellular fluid compartment. It does reduce the incidence of metabolic acidosis calculated in blood and the need for fetal blood sampling without affecting the Apgar score, neonatal admissions, hypoxic-ischemic encephalopathy, or operative deliveries. LEVEL OF EVIDENCE: I.

Indirect maternal mortality increases in the Netherlands.

OBJECTIVE: To assess causes, trends, and substandard care in indirect maternal mortality in the Netherlands. DESIGN: Confidential enquiry into causes of maternal death. SETTING: Nationwide in the Netherlands. POPULATION: A total of 2,557,208 live births. METHODS: Data analysis of indirect maternal deaths in the period 1993-2005. MAIN OUTCOME MEASURES: Indirect maternal mortality. RESULTS: Of the study subjects, 97 were classified as indirect deaths, representing a maternal mortality ratio of 3.3/100,000 live births, a significant increase compared to the preceding enquiry in the period 1983-1992 (MMR 2.4, OR 1.5, 95%CI 1.0-2.1). The percentage of cases not directly reported to the Maternal Mortality Committee decreased from 15 to 5%. Cardiovascular disorders were the leading cause of indirect maternal mortality, followed by cerebrovascular disorders. Vascular dissection (n = 19) was the most frequent specified cause of death. Risk factors were advanced maternal age, non-indigenous origin (Surinam and Dutch Antilles), and medical health risks before pregnancy. Substandard care was present in 35%, mainly being misjudgment of the severity of the condition and delay in initiating therapy. CONCLUSION: The rise of mortality due to indirect causes is considered a reflection of the change in risk profile of women of childbearing age and the result of demographic alterations concerning ethnicity and maternal age. The identification of high risk groups, preferably by programs of preconception care, should lead to improved care for these women, with a multidisciplinary approach when needed.

Maternal mortality and severe morbidity from sepsis in the Netherlands.

OBJECTIVE: To assess incidence and risk factors of maternal mortality and severe morbidity from sepsis in the Netherlands. DESIGN: A nationwide confidential enquiry into maternal mortality from 1993 to 2006 and severe maternal morbidity from 2004 to 2006. SETTING: All 98 Dutch maternity units in the Netherlands. POPULATION: All pregnant women in the Netherlands from 1993 to 2006. METHODS: All reported cases of maternal death from sepsis during 1993-2006 were reported to the Maternal Mortality Committee. Cases of severe maternal morbidity from sepsis from 2004 to 2006 were collected in a nationwide design. Main outcome measures. Incidence, case fatality rates, and possible risk factors. RESULTS: The maternal mortality ratio from direct maternal mortality from sepsis was 0.73 per 100,000 live births (20/2,742,265). The incidence of severe maternal morbidity from sepsis was 21 per 100,000 deliveries (78/371,021), of which 79% was admitted to the intensive care unit. High age, multiple pregnancies, and the use of artificial reproduction techniques were significant risk factors for developing sepsis in univariate analysis. The overall case fatality rate for sepsis during 2004-2006 was 7.7% (6/78). Group A streptococcal infection was in 42.9% (9/21), the cause of direct maternal mortality from sepsis (1993-2006). In 31.8% (14/44), Group A streptococcal infection was the cause of obstetric morbidity from sepsis (2004-2006). CONCLUSIONS: With a case fatality rate of 7.7%, sepsis is a life threatening condition for women during pregnancy, childbirth, and puerperium.

Maternal death after oocyte donation at high maternal age: case report.

BACKGROUND: The percentage of women giving birth after the age of 35 increased in many western countries. The number of women remaining childless also increased, mostly due to aging oocytes. The method of oocyte donation offers the possibility for infertile older women to become pregnant. Gestation after oocyte-donation-IVF, however, is not without risks for the mother, especially at advanced age. CASE PRESENTATION: An infertile woman went abroad for oocyte-donation-IVF, since this treatment is not offered in The Netherlands after the age of 45. The first oocyte donation treatment resulted in multiple gestation, but was ended by induced abortion: the woman could not cope with the idea of being pregnant with twins. During the second pregnancy after oocyte donation, at the age of 50, she was mentally more stable. The pregnancy, again a multiple gestation, was uneventful until delivery. Immediately after delivery the woman had hypertension with nausea and vomiting. A few hours later she had an eclamptic fit. HELLP-syndrome was diagnosed. She died due to cerebral haemorrhage. CONCLUSION: In The Netherlands, the age limit for women receiving donor oocytes is 45 years and commercial oocyte donation is forbidden by law. In other countries there is no age limit, the reason why some women are going abroad to receive the treatment of their choice. Advanced age, IVF and twin pregnancy are all risk factors for pre-eclampsia, the leading cause of maternal death in The Netherlands.Patient autonomy is an important ethical principle, but doctors are also bound to the principle of 'not doing harm', and do have the right to refuse medical treatment such as IVF-treatment. The discussion whether women above 50 should have children is still not closed. If the decision is made to offer this treatment to a woman at advanced age, the doctor should counsel her intensively about the risks before treatment is started.

A randomised clinical trial on cardiotocography plus fetal blood sampling versus cardiotocography plus ST-analysis of the fetal electrocardiogram (STAN) for intrapartum monitoring.

BACKGROUND: Cardiotocography (CTG) is worldwide the method for fetal surveillance during labour. However, CTG alone shows many false positive test results and without fetal blood sampling (FBS), it results in an increase in operative deliveries without improvement of fetal outcome. FBS requires additional expertise, is invasive and has often to be repeated during labour. Two clinical trials have shown that a combination of CTG and ST-analysis of the fetal electrocardiogram (ECG) reduces the rates of metabolic acidosis and instrumental delivery. However, in both trials FBS was still performed in the ST-analysis arm, and it is therefore still unknown if the observed results were indeed due to the ST-analysis or to the use of FBS in combination with ST-analysis. METHODS/DESIGN: We aim to evaluate the effectiveness of non-invasive monitoring (CTG + ST-analysis) as compared to normal care (CTG + FBS), in a multicentre randomised clinical trial setting. Secondary aims are: 1) to judge whether ST-analysis of fetal electrocardiogram can significantly decrease frequency of performance of FBS or even replace it; 2) perform a cost analysis to establish the economic impact of the two treatment options. Women in labour with a gestational age > or = 36 weeks and an indication for CTG-monitoring can be included in the trial. Eligible women will be randomised for fetal surveillance with CTG and, if necessary, FBS or CTG combined with ST-analysis of the fetal ECG. The primary outcome of the study is the incidence of serious metabolic acidosis (defined as pH < 7.05 and Bdecf > 12 mmol/L in the umbilical cord artery). Secondary outcome measures are: instrumental delivery, neonatal outcome (Apgar score, admission to a neonatal ward), incidence of performance of FBS in both arms and cost-effectiveness of both monitoring strategies across hospitals. The analysis will follow the intention to treat principle. The incidence of metabolic acidosis will be compared across both groups. Assuming a reduction of metabolic acidosis from 3.5% to 2.1 %, using a two-sided test with an alpha of 0.05 and a power of 0.80, in favour of CTG plus ST-analysis, about 5100 women have to be randomised. Furthermore, the cost-effectiveness of CTG and ST-analysis as compared to CTG and FBS will be studied. DISCUSSION: This study will provide data about the use of intrapartum ST-analysis with a strict protocol for performance of FBS to limit its incidence. We aim to clarify to what extent intrapartum ST-analysis can be used without the performance of FBS and in which cases FBS is still needed. TRIAL REGISTRATION NUMBER: ISRCTN95732366.
