RESUMEN
BACKGROUND: Congenital anomalies represent an important global health issue. Data on the prevalence and pattern of congenital anomalies in the Caribbean region are scarce and lacking altogether in Aruba, Bonaire and Curaçao (ABC islands). METHODS: We performed a population-based surveillance study to determine the prevalence of structural congenital anomalies in the ABC islands, including all live births and stillbirths between January 1, 2008 and December 31, 2017 with major congenital anomalies according to EUROCAT guide 1.5. Terminations of pregnancy for fetal anomaly were included as well. Cases were identified by active case ascertainment, using multiple sources including pediatric patient files and discharge letters, delivery records, and clinical genetic patient files. Total and subgroup prevalence rates were compared between the three islands and to the French West Indies and Northern Netherlands. RESULTS: Total prevalence of congenital anomalies on the ABC islands was 242.97 per 10,000 births. Total prevalence of congenital anomalies in Bonaire (325.15 per 10,000 births) was higher compared to Aruba (233.29 per 10,000 births) and Curaçao (238.58 per 10,000 births), which was mainly attributable to a higher prevalence of limb anomalies, in particular polydactyly, in Bonaire. Total prevalence of congenital anomalies on the ABC islands was comparable to the French West Indies (248.69 per 10,000 births) but significantly lower compared to the Northern Netherlands (298.98 per 10,000 births). In the subgroup prevalence analysis, the prevalence of polydactyly and atrial septal defect on the ABC islands was significantly higher compared with the French West Indies and the Northern Netherlands, while the prevalence of congenital anomalies of the kidney and urinary tract and genetic disorders was significantly lower. CONCLUSIONS: This is the first study to establish the prevalence and pattern of congenital anomalies on the ABC islands, which is important to inform healthcare managers and policymakers and to provide a basis for continuous surveillance of congenital anomalies.

OBJECTIVE: Hazardous working conditions increase the risk of adverse pregnancy outcomes. In this study, we examine adherence to legislation and guidelines aimed at improving working conditions in pregnancy. METHODS: Between 2014 and 2016, we recruited a prospective cohort of low-risk nulliparous pregnant women in paid employment or self-employed in 16 community midwifery practices in The Netherlands. Participants completed two questionnaires concerning demographics, education, general health and working conditions between 10-16 and 20-24 weeks of pregnancy. We calculated the proportion of participants with work-related risk factors not in accordance with legislation and/or guidelines. RESULTS: Of 269 participants included, 214 (80%) completed both questionnaires. At 10-16 weeks 110 (41%) participants and at 20-24 weeks 129 (63%) participants continued to work under circumstances that did not meet recommendations. Employers provided mandated information on work adjustment to 37 (15%) participants and 96 (38%) participants received no information about the potential hazards while working with biological and chemical hazards. Participants with lower educational attainment (aOR 2.2 95%CI 1.3-3.9), or employment in healthcare (aOR 4.5, 95%CI 2.2-9.0), education/childcare and social service (aOR 2.6, 95%CI 1.1-6.0 2),, catering (aOR 3.6, 95%CI 1.1-12) and industry, construction and cleaning (aOR 3.3, 95%CI 1.1-10.3) more often continued work which did not meet recommendations. CONCLUSION: There is poor adherence to national legislation and guidelines for safe working in pregnancy in The Netherlands: 50% of the pregnant women worked under hazardous conditions. Given the impact on adverse pregnancy outcomes as well as on the public purse, action to improve compliance must be taken by all stakeholders.

Introduction: Spontaneous preterm birth (sPTB) is a major contributor to neonatal morbidity and mortality worldwide. The pathophysiology of sPTB is poorly understood, in particular among nulliparous women without apparent medical or obstetric risk factors. Therefore, we aimed to identify risk factors for sPTB in healthy nulliparous women. Material and Methods: We performed a prospective cohort study. Recruitment took place from February 2014 to December 2016 in 16 community midwifery centers in the Netherlands. Eligibility criteria were: ≥18 years, no previous pregnancy >16 weeks of gestation, healthy singleton pregnancy, and antenatal booking <24 weeks of gestation. At study inclusion, participants completed a questionnaire, including details on lifestyle, work, and medical history. Cervical length was measured by vaginal ultrasound at the second-trimester anomaly scan. Detailed information concerning pregnancy and birth was collected via antenatal charts. We calculated the adjusted odds ratio (aOR) and 95% confidence intervals (CI) for various risk factors with correction for socioeconomic status (SES) using logistic regression and Firth's correction. Results: We included 363 women of whom pregnancy outcomes were available in 349 (96.1%) participants. The cervical length measurement was available for 225 (62.0%) participants. sPTB occurred in 26 women (7.5%). SES was associated with sPTB (OR: 3.7, 95% CI: 1.6-8.5) in univariate analysis. First or second trimester vaginal bleeding (aOR: 3.6, 95% CI: 1.4-9.0) and urinary tract infection during pregnancy (aOR: 4.9, 95% CI: 1.7-13.9) were associated with sPTB in multivariate analysis. Conclusions: This prospective cohort confirms established risk factors for sPTB in nulliparous women deemed at low risk of sPTB.
RESUMEN
OBJECTIVE: To study the impact of fetal gender on the risk of spontaneous preterm birth in various ethnicities. STUDY DESIGN: National cohort study in which all singleton live births from 25+0 weeks onwards without congenital anomalies were included of African, Asian, and Mediterranean women (1999-2010). Our primary outcome measure was preterm birth before 37 weeks. Per ethnic group, male and female neonates were compared. RESULT: In each ethnic group, male fetuses were at increased risk of preterm birth (adjusted odds ratio (aOR) 1.63 for African, aOR 1.71 for Asian, and aOR 1.84 for Mediterranean males). The population-attributable risk of male gender on spontaneous preterm birth is lower in African women (3.9%) than in Asian (10.3%) and Mediterranean women (9.0%). CONCLUSION: Male fetal gender is associated with spontaneous preterm birth in African, Asian, and Mediterranean women, but the total impact of ethnicity on spontaneous preterm birth rate is different.

RESEARCH QUESTION: What valid guideline-based quality indicators can measure quality of care in early pregnancy assessment units (EPAU)? DESIGN: The systematic RAND-modified Delphi method was used to develop an indicator set from four evidence-based guidelines. An international expert panel was assembled to extract recommendations from these guidelines to establish quality indicators. RESULTS: A total of 119 recommendations were extracted. Eleven recommendations received a high median score and top five score above the 75th percentile and were selected as key recommendations. The expert panel reassessed 15 high score recommendations and top five score between the 50th and 75th percentile as well as one high score recommendation without consensus. Eight of these 16 recommendations were selected in the second round as key recommendations. The key recommendations were formulated into a set of 19 quality indicators, summarized as follows: women referred to an EPAU could be seen within 24 h and receive a clear explanation on treatment options; designated senior staff members could be responsible for the unit and staff could have had ultrasound training; protocols could be available for daily practice covering all treatment options for miscarriage and ectopic pregnancy; and an EPAU could have access to urine pregnancy testing and serum HCG assays. CONCLUSIONS: Nineteen quality indicators to measure early pregnancy care provided by EPAU were identified.

OBJECTIVE: This systematic review aims to identify, critically appraise and summarize the results of studies examining the relationship between the vaginal microbiota and preterm birth (PTB). METHODS: We searched the electronic databases Medline, EMBASE and the Cochrane Controlled Register of Trials for studies in any language reporting on vaginal microbiota and PTB published from 1990 to November 29th, 2017. We included any study that performed lower genital tract microbiota assessment in asymptomatic pregnant women and reported on spontaneous preterm birth, with either intact or ruptured membranes. RESULTS: The search strategy yielded 2171 unique citations, of which nine studies were eligible for inclusion in this review. In six studies an association was found between the composition of the vaginal microbiota and PTB, but findings differed between subgroups, ethnicities and degree of risk of PTB. In three studies no association was found. Two of these studies found a significant difference in richness and Shannon diversity between term and PTB. CONCLUSIONS: We have demonstrated that there is a paucity of molecular based, culture-independent studies that analyse the relationship between the vaginal microbiota and PTB as an outcome. The heterogeneity precluded a meta-analysis. Studies provide contradictory evidence and the quality of the clinical information in the studies is poor. To improve quality of future studies we have provided a database of essential and desirable items of quality that are method and topic specific.

INTRODUCTION: Fetal gender is associated with preterm birth; however, a proper subdivision by onset of labor and corresponding neonatal outcome by week of gestation is lacking. MATERIAL AND METHODS: Data from the Netherlands Perinatal Registry (1999-2010) were used to calculate relative risk ratios for gender by week of gestation and gender-related risk on adverse neonatal outcomes using a moving average technique. White European women with an alive fetus at onset of labor were included. Adverse neonatal outcomes were defined as neonatal mortality and a composite of neonatal morbidity. Onset of labor was categorized as spontaneous onset with intact membranes, premature rupture of membranes, and induction or elective cesarean section. RESULTS: The study population comprised 1 736 615 singleton deliveries (25(+0) -42(+6) weeks). Male fetuses were at increased risk of spontaneous preterm birth with intact membranes compared with a female fetus with a peak between 27 and 31 weeks [relative risk (RR) 1.5; 95% CI 1.4-1.6]. Male fetuses were also at increased risk of preterm premature rupture of membranes between 27 and 37 weeks (RR 1.2; 95% CI 1.16-1.23). No gender effect was seen for medically indicated preterm birth. No significant differences were seen for neonatal mortality. Males were at significantly increased risk of composite neonatal morbidity from 29 weeks onwards (RR 1.3; 95% CI 1.3-1.4). CONCLUSIONS: Male fetal gender is a relevant risk factor for spontaneous preterm birth, both for intact membranes and for preterm premature rupture of membranes in white European women. In addition, male infants are at increased risk of neonatal morbidity.

OBJECTIVE: To study the impact on health-related quality of life (HRQoL) of treatment with systemic methotrexate (MTX) or expectant management in women with ectopic pregnancy or pregnancy of unknown location (PUL) with low and plateauing serum hCG concentrations. STUDY DESIGN: HRQoL was assessed alongside a randomized clinical trial (RCT) with the use of standard self-administered psychometric measure questionnaires. PATIENTS AND SETTING: All women who participated in the multicenter RCT comparing treatment with systemic MTX to expectant management in women with ectopic pregnancy or persisting PUL were eligible for the HRQoL measurements. MAIN OUTCOME MEASURE: HRQoL measures of three standardized questionnaires (SF-36, RSCL, HADS). RESULTS: Data were available for 64 of 73 women (78%) randomized in the RCT. We found no difference in HRQoL between the two treatment groups. The need for additional treatment, i.e. additional MTX injections or surgical intervention, had no impact on HRQoL. CONCLUSION: Women treated with MTX or expectant management for an ectopic pregnancy or persisting PUL have comparable quality of life.

In this observational study, the effect of the introduction of the first Early Pregnancy Assessment Unit (EPAU) in a university hospital in The Netherlands in 2008 on early pregnancy care is analysed. Derivatives of quality of care were measured before and after the establishment of the EPAU, with the aim of reducing unnecessary care. Care within three time periods was measured: 2006, 2009 and 2012. In 2006, 14% of women who had experienced a miscarriage were admitted to the hospital, whereas in 2009 and 2012 no women were admitted. The surgical management rate for miscarriage decreased from 79% (2006) to 6% (2009) and 28% (2012). Karyotyping of couples who had experienced recurrent miscarriage decreased from 100% (2006) to 17% (2009) and 33% (2012). The surgical management rate for ectopic pregnancy decreased from 50% (2006) to 25% (2009) and 29% (2012). The mean total cost per woman treated in 2006 was 1111 (95% CI 808 to 1426), 436 (95% CI 307 to 590) in 2009 and 633 (95% CI 586 to 788) in 2012. We can therefore conclude that an EPAU results in higher quality and cost-effective care, and has a positive effect on early pregnancy care.

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.

OBJECTIVE: To estimate costs of preterm birth in singleton and multiple pregnancies. STUDY DESIGN: Cost analysis based on data from a prospective cohort study and three multicentre randomised controlled trials (2006-2012) in a Dutch nationwide consortium for women's health research. Women with preterm birth before 37 completed weeks were included for analysis. Direct costs were estimated from a health care perspective, from delivery until discharge or decease of the neonates. Costs and adverse perinatal outcome per pregnancy were measured. Adverse perinatal outcome comprised both perinatal mortality and a composite of neonatal morbidity defined as chronic lung disease, intraventricular haemorrhage≥grade 2, periventricular leukomalacia≥grade 1, proven sepsis or necrotising enterocolitis. Using a moving average technique covering three weeks per measurement, costs and adverse perinatal outcome per woman delivering for every week between 24 and 37 weeks are reported. RESULTS: Data of 2802 women were available of whom 1503 (53.6%) had a preterm birth; 501 in 1090 singleton (46%) and 1002 in 1712 multiple pregnancies (58.5%). The most frequent perinatal outcomes were perinatal mortality, chronic lung disease and sepsis. For singleton pregnancies the peak of total costs was at 25 weeks (88,052 per delivery), compared to 27 weeks for multiple pregnancies (169,571 per delivery). The total costs declined rapidly with increasing duration of pregnancy. Major cost drivers were length of stay on the NICU and airway treatments. The peaks seen in costs paralleled with the prevalence of adverse perinatal outcome. CONCLUSIONS: These data can be used to elaborate on the impact of preterm birth in case only data are available on duration of pregnancy.

BACKGROUND: Tubal ectopic pregnancy can be surgically treated by salpingectomy, in which the affected Fallopian tube is removed, or salpingotomy, in which the tube is preserved. Despite potentially increased risks of persistent trophoblast and repeat ectopic pregnancy, salpingotomy is often preferred over salpingectomy because the preservation of both tubes is assumed to offer favourable fertility prospects, although little evidence exists to support this assumption. We aimed to assess whether salpingotomy would improve rates of ongoing pregnancy by natural conception compared with salpingectomy. METHODS: In this open-label, multicentre, international, randomised controlled trial, women aged 18 years and older with a laparoscopically confirmed tubal pregnancy and a healthy contralateral tube were randomly assigned via a central internet-based randomisation program to receive salpingotomy or salpingectomy. The primary outcome was ongoing pregnancy by natural conception. Differences in cumulative ongoing pregnancy rates were expressed as a fecundity rate ratio with 95% CI, calculated by Cox proportional-hazards analysis with a time horizon of 36 months. Secondary outcomes were persistent trophoblast and repeat ectopic pregnancy (expressed as relative risks [RRs] with 95% CIs) and ongoing pregnancy after ovulation induction, intrauterine insemination, or IVF. The researchers who collected data for fertility outcomes were masked to the assigned intervention, but patients and the investigators who analysed the data were not. All endpoints were analysed by intention to treat. We also did a (non-prespecified) meta-analysis that included the findings from the present trial. This trial is registered, number ISRCTN37002267. FINDINGS: 446 women were randomly assigned between Sept 24, 2004, and Nov 29, 2011, with 215 allocated to salpingotomy and 231 to salpingectomy. Follow-up was discontinued on Feb 1, 2013. The cumulative ongoing pregnancy rate was 60·7% after salpingotomy and 56·2% after salpingectomy (fecundity rate ratio 1·06, 95% CI 0·81-1·38; log-rank p=0·678). Persistent trophoblast occurred more frequently in the salpingotomy group than in the salpingectomy group (14 [7%] vs 1 [<1%]; RR 15·0, 2·0-113·4). Repeat ectopic pregnancy occurred in 18 women (8%) in the salpingotomy group and 12 (5%) women in the salpingectomy group (RR 1·6, 0·8-3·3). The number of ongoing pregnancies after ovulation induction, intrauterine insemination, or IVF did not differ significantly between the groups. 43 (20%) women in the salpingotomy group were converted to salpingectomy during the initial surgery because of persistent tubal bleeding. Our meta-analysis, which included our own results and those of one other study, substantiated the results of the trial. INTERPRETATION: In women with a tubal pregnancy and a healthy contralateral tube, salpingotomy does not significantly improve fertility prospects compared with salpingectomy.

BACKGROUND: Medical treatment with misoprostol is a non-invasive and inexpensive treatment option in first trimester miscarriage. However, about 30% of women treated with misoprostol have incomplete evacuation of the uterus. Despite being relatively asymptomatic in most cases, this finding often leads to additional surgical treatment (curettage). A comparison of effectiveness and cost-effectiveness of surgical management versus expectant management is lacking in women with incomplete miscarriage after misoprostol. METHODS/DESIGN: The proposed study is a multicentre randomized controlled trial that assesses the costs and effects of curettage versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.Eligible women will be randomized, after informed consent, within 24 hours after identification of incomplete evacuation of the uterus by ultrasound scanning. Women are randomly allocated to surgical or expectant management. Curettage is performed within three days after randomization.Primary outcome is the sonographic finding of an empty uterus (maximal diameter of any contents of the uterine cavity < 10 millimeters) six weeks after study entry. Secondary outcomes are patients' quality of life, surgical outcome parameters, the type and number of re-interventions during the first three months and pregnancy rates and outcome 12 months after study entry. DISCUSSION: This trial will provide evidence for the (cost) effectiveness of surgical versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.

Nowadays ectopic pregnancy often can be diagnosed before the woman's condition has deteriorated, which has altered the former clinical picture of a life-threatening disease into a more benign condition. This review describes the historical developments in the diagnostic and therapeutic management of ectopic pregnancy leading up to current clinical practice. The first attempts to diagnose ectopic pregnancy originate from the beginning of the 20th century.

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.

OBJECTIVE: To study the association between patient-related risk factors and severe maternal morbidity in women with tubal ectopic pregnancy (EP). Furthermore, to identify substandard care factors in clinical care management of EP. DESIGN: Case-control study. SETTING: Not applicable. PATIENT(S): Case subjects were from the LEMMoN study, a prospective nationwide cohort study. Control subjects were from the ESEP study, an international multicenter randomized controlled trial. INTERVENTION(S): Case subjects were women with tubal EP complicated by severe intra-abdominal hemorrhage necessitating blood transfusion of ≥4 units of packed red blood cells peri- or postoperatively. Control subjects were women with tubal EP who were hemodynamically stable and surgically treated. MAIN OUTCOME MEASURE(S): Patient-related risk factors as: maternal age, gestational age, previous EP, Chlamydia infection, pelvic inflammatory disease, assisted reproductive techniques, and serum hCG level. Substandard care categories classified as unawareness of the clinician, misdiagnosis, and nonadherence to the guideline on EP. RESULT(S): Twenty-nine case subjects and 99 control subjects were included. The mean serum hCG level was significantly higher in case subjects compared with control subjects, but we found no reliable cutoff level of serum hCG to rule out maternal morbidity. Other risk factors did not differ significantly. Substandard care was scored more often in case subjects (43%) than in control subjects (14%), mainly concerning misdiagnosis. CONCLUSION(S): No patient-related risk factors for severe intra-abdominal hemorrhage in women with tubal EP were identified. Our findings underpin the importance of awareness of EP among young fertile women and care providers and clinical care management according to the guidelines to prevent severe maternal morbidity.

OBJECTIVE: To improve the interpretation of future studies in women who are initially diagnosed with a pregnancy of unknown location (PUL), we propose a consensus statement with definitions of population, target disease, and final outcome. DESIGN: A review of literature and a series of collaborative international meetings were used to develop a consensus for definitions and final outcomes of women initially diagnosed with a PUL. RESULT(S): Global differences were noted in populations studied and in the definitions of outcomes. We propose to define initial ultrasound classification of findings into five categories: definite ectopic pregnancy (EP), probable EP, PUL, probable intrauterine pregnancy (IUP), and definite IUP. Patients with a PUL should be followed and final outcomes should be categorized as visualized EP, visualized IUP, spontaneously resolved PUL, and persisting PUL. Those with the transient condition of a persisting PUL should ultimately be classified as nonvisualized EP, treated persistent PUL, resolved persistent PUL, or histologic IUP. These specific categories can be used to characterize the natural history or location (intrauterine vs. extrauterine) of any early gestation where the initial location is unknown. CONCLUSION(S): Careful definition of populations and classification of outcomes should optimize objective interpretation of research, allow objective assessment of future reproductive prognosis, and hopefully lead to improved clinical care of women initially identified to have a PUL.

OBJECTIVE: The incidence of ectopic pregnancy (EP) was reported to rise during the 1970s and 1980s; thereafter it remained stable or even declined. We studied whether changes in the incidence of pelvic inflammatory disease (PID) have had an impact on the incidence of EP and we hypothesise about the incidence of EP in the near future. STUDY DESIGN: EP and PID hospital admissions from 1980 to 2005 were derived from Dutch Medical Registries and incidence trends were calculated and analysed by joinpoint regression. RESULTS: The peak incidence of EP in 1988 (11/1000 live births) was preceded by a peak incidence of admissions for PID in 1983 (0.6/1000 women of all ages). The EP rate declined towards 2005 (7.3/1000 live births) mainly due to a decrease in EP in urban regions and in older aged women (> or =35 years). Presently, women <25 years and born between 1985 and 1990 are again at an increased risk of EP (12/1000 live births) but this rise was not preceded by a peak incidence of admissions for PID. CONCLUSION: On a population level, the peak incidence of EP in The Netherlands was preceded by a peak incidence of PID. A renewed rise in the incidence of EP is observed for young women. This may be related to the significant increase in positive tests for genital Chlamydia trachomatis during recent years.

Problems in the first trimester of pregnancy frequently occur. Examples are miscarriage, ectopic pregnancy and recurrent miscarriage. In Dutch hospitals there is a growing interest in the setting up of 'early pregnancy units' (EPUs). The aim of these EPUs is to improve the quality of care for women with early pregnancy problems by centralising the care and knowledge available. This centralisation could prevent over- and underdiagnosis and over- and undertreatment. Moreover, EPUs could improve the logistics of clinical research. The potential effectiveness of these units in the Netherlands still needs to be investigated.

BACKGROUND: Patients with ectopic pregnancy (EP) and low serum hCG concentrations and women with a pregnancy of unknown location (PUL) and plateauing serum hCG levels are commonly treated with systemic methotrexate (MTX). However, there is no evidence that treatment in these particular subgroups of women is necessary as many of these early EPs may resolve spontaneously. The aim of this study is whether expectant management in women with EP or PUL and with low but plateauing serum hCG concentrations is an alternative to MTX treatment in terms of treatment success, future pregnancy, health related quality of life and costs. METHODS/DESIGN: A multicentre randomised controlled trial in The Netherlands. Hemodynamically stable patients with an EP visible on transvaginal ultrasound and a plateauing serum hCG concentration < 1,500 IU/L or with a persisting PUL with plateauing serum hCG concentrations < 2,000 IU/L are eligible for the trial. Patients with a viable EP, signs of tubal rupture/abdominal bleeding, or a contra-indication for MTX will not be included. Expectant management is compared with systemic MTX in a single dose intramuscular regimen (1 mg/kg) in an outpatient setting. Serum hCG levels are monitored weekly; in case of inadequately declining, systemic MTX is installed or continued. In case of hemodynamic instability and/or signs of tubal rupture, surgery is performed. The primary outcome measure is an uneventful decline of serum hCG to an undetectable level by the initial intervention. Secondary outcomes are (re)interventions (additional systemic MTX injections and/or surgery), treatment complications, health related quality of life, financial costs, and future fertility. Analysis is performed according to the intention to treat principle. Quality of life is assessed by questionnaires before and at three time points after randomisation. Costs are expressed as direct costs with data on costs and used resources in the participating centres. Fertility is assessed by questionnaires after 6, 12, 18 and 24 months. Patients' preferences will be assessed using a discrete choice experiment. DISCUSSION: This trial will provide guidance on the present management dilemmas in women with EPs and PULs with low and plateauing serum hCG concentrations.
