Profiling the preterm or VLBW born adolescent; implications of the Dutch POPS cohort follow-up studies.

In 1983, data of a unique nationwide cohort of 1338 very preterm (<32 weeks of gestation) or VLBW (birth weight<1500g) infants in the Netherlands was collected and followed at several ages until they reached the age of 19 years. At 19 years of age a more extensive follow-up study was done, including questionnaires, tests on a computer and a full physical exam. These studies provide insight into how Dutch adolescents at 19 years of age, who were born very preterm or with a very low birth weight (VLBW), reach adulthood. At 19 years, 705 POPS participants participated (74% of 959 still alive). Outcome measures at 19 years included: physical outcomes (e.g. blood pressure), cognition, behavior, quality of life, and impact of handicaps. The POPS participants showed more impairments on most outcome measures at various ages, compared to norm data. Major handicaps remained stable as the children grew older, but minor handicaps and disabilities increased. At 19 years of age, only half (47.1%) of the survivors had no disabilities and no minor or major handicaps. Especially those born small for gestational age (SGA) seem most vulnerable. These long-term results help to support preterm and SGA born children and adolescents in reaching independent adulthood, and stress the need for long term follow-up studies and to promote prevention of disabilities and of preterm birth itself.

Intelligence of very preterm or very low birthweight infants in young adulthood.

OBJECTIVE: To examine the effect of intrauterine and neonatal growth, prematurity and personal and environmental risk factors on intelligence in adulthood in survivors of the early neonatal intensive care era. METHODS: A large geographically based cohort comprised 94% of all babies born alive in the Netherlands in 1983 with a gestational age below 32 weeks and/or a birth weight >1500 g (POPS study). Intelligence was assessed in 596 participants at 19 years of age. Intrauterine and neonatal growth were assessed at birth and 3 months of corrected age. Environmental and personal risk factors were maternal age, education of the parent, sex and origin. RESULTS: The mean (SD) IQ of the cohort was 97.8 (15.6). In multiple regression analysis, participants with highly educated parents had a 14.2-point higher IQ than those with less well-educated parents. A 1 SD increase in birth weight was associated with a 2.6-point higher IQ, and a 1-week increase in gestational age was associated with a 1.3-point higher IQ. Participants born to young mothers (<25 years) had a 2.7-point lower IQ, and men had a 2.1-point higher IQ than women. The effect on intelligence after early (symmetric) intrauterine growth retardation was more pronounced than after later (asymmetric) intrauterine or neonatal growth retardation. These differences in mean IQ remained when participants with overt handicaps were excluded. CONCLUSIONS: Prematurity as well as the timing of growth retardation are important for later intelligence. Parental education, however, best predicted later intelligence in very preterm or very low birthweight infants.

[Sensible family planning: pitfalls and dilemmas]. / Verstandige gezinsplanning: valkuilen en dilemma's.

In a recent article in this journal it was stated that Dutch women were sensible in having their first child between the ages of 25 and 35 years. One of the conclusions was that associated health risks increase after the age of 35 but are still acceptable even at the age of 40. We demonstrate that these conclusions were based on flawed assumptions. Postponing pregnancy until after the age of 30 increases the risks of infertility and breast cancer. Motherhood at a later age is associated with an increase in obstetrical complications, miscarriage and other adverse effects on the child. Therefore, for couples planning a family with 2 children or more, it would be sensible to have the first pregnancy not long after the mother reaches the age of 30 years, or even earlier. Couples should be informed on the risks of late parenthood in order to be able to take the right decisions concerning family planning.

Evaluation of 280,000 cases in Dutch midwifery practices: a descriptive study.

OBJECTIVE: To assess the nature and outcome of intrapartum referrals from primary to secondary care within the Dutch obstetric system. DESIGN: Descriptive study. SETTING: Dutch midwifery database (LVR1), covering 95% of all midwifery care and 80% of all Dutch pregnancies (2001-03). POPULATION: Low-risk women (280,097) under exclusive care of a primary level midwife at the start of labour either with intention to deliver at home or with a personal preference to deliver in hospital under care of a primary level midwife. METHODS: Women were classified into three categories (no referral, urgent referral and referral without urgency) and were related to maternal characteristics and to neonatal outcomes. MAIN OUTCOME MEASURES: Distribution of referral categories, main reasons for urgent referral, Apgar score at 5 minutes, perinatal death within 24 hours and referral to a paediatrician within 24 hours. RESULTS: In our study, 68.1% of the women completed childbirth under exclusive care of a midwife, 3.6% were referred on an urgency basis and 28.3% were referred without urgency. Of all referrals, 11.2% were on an urgency basis. The main reasons for urgent referrals were fetal distress and postpartum haemorrhage. The nonurgent referrals predominantly took place during the first stage of labour (73.6% of all referrals). Women who had planned a home delivery were referred less frequently than women who had planned a hospital delivery: 29.3 and 37.2%, respectively (P < 0.001). On average, the mean Apgar score at 5 minutes was high (9.72%) and the peripartum neonatal mortality was low (0.05%) in the total study group. No maternal deaths occurred. Adverse neonatal outcomes occurred most frequently in the urgent referral group, followed by the group of referrals without urgency and the nonreferred group. CONCLUSIONS: Risk selection is a crucial element of the Dutch obstetric system and continues into the postpartum period. The system results in a relatively small percentage of intrapartum urgent referrals and in overall satisfactory neonatal outcomes in deliveries led by primary level midwives.

Behavioural and emotional problems in very preterm and very low birthweight infants at age 5 years.

BACKGROUND: Children born very preterm (VP; <32 weeks' gestation) or with very low birth weight (VLBW, <1500 g; hereafter called VP/VLBW) are at risk for behavioural and emotional problems during school age and adolescence. At school entrance these problems may hamper academic functioning, but evidence on their occurrence at this age in VP/VLBW children is lacking. AIM: To provide information on academic functioning of VP/VLBW children and to examine the association of behavioural and emotional problems with other developmental problems assessed by paediatricians. DESIGN, SETTING AND PARTICIPANTS: A cohort of 431 VP/VLBW children aged 5 years (response rate 76.1%) was compared with two large national samples of children of the same age (n = 6007, response rate 86.9%). OUTCOME MEASURES: Behavioural and emotional problems measured by the Child Behavior Checklist (CBCL), and paediatrician assessment of other developmental domains among VP/VLBW children. RESULTS: The prevalence rate of a CBCL total problems score in the clinical range was higher among VP/VLBW children than among children of the same age from the general population (13.2% v 8.7%, odds ratio 1.60 (95% confidence interval 1.18 to 2.17)). Mean differences were largest for social and attention problems. Moreover, they were larger in children with paediatrician-diagnosed developmental problems at 5 years, and somewhat larger in children with severe perinatal problems. CONCLUSION: At school entrance, VP/VLBW children are more likely to have behavioural and emotional problems that are detrimental for academic functioning. Targeted and timely help is needed to support them and their parents in overcoming these problems and in enabling them to be socially successful.

Management of the neonate at the limits of viability: the Dutch viewpoint.

Due to ever-improving medical technology over the course of the last century, the limit of viability has been lowered from around 32 weeks of gestation, first to 28 weeks and, in recent decades, to as low as less than 24 weeks. Long-term follow-up studies (Project on Preterm and Small-for-Gestational-Age Infants, Leiden Follow-up Project on Prematurity, Epidemiological Project for ICU Research and Evaluation, Etude Epidémiologique sur les Petits Ages Gestationnels, Extremely Preterm Infants in Belgium), however, have shown high percentages of deaths and/or disabilities at lower gestational ages in surviving children. Many parents and children are burdened with lifelong iatrogenic disabilities. As a result, the Dutch Paediatric Association and the Dutch Society of Obstetrics and Gynaecology have laid down joint rules for the management of expected/threatened preterm delivery.

Nonresponse bias in a follow-up study of 19-year-old adolescents born as preterm infants.

OBJECTIVE: To assess the effect of demographic and neonatal risk factors and outcome at the last available assessment on the probability of full responders, postal responders (those who only responded to the mailed questionnaire), or nonresponders in a follow-up study of 19-year-old adolescents who were born as preterm infants. DESIGN: The 19-year follow-up program was part of a large ongoing collaborative study in The Netherlands on the long-term effect of prematurity and dysmaturity on various medical, psychological, and social parameters. In the original cohort, 1338 infants (94%) with a gestational age of < 32 weeks and/or a birth weight of < 1500 g were enrolled. Neonatal mortality was 23% (n = 312), and another 67 children had died between the ages of 28 days and 19 years, leaving 959 survivors (72% of the original cohort) for follow-up at the present assessment. To study the effect of nonresponse, we divided the 959 survivors into 3 groups: full responders (596 [62.1%]), postal responders (109 [11.4%]), and nonresponders (254 [26.5%]). In the 3 groups we compared demographic and neonatal data, as well as outcome at the last available assessment. RESULTS: The odds ratios (ORs) for male versus female for the probabilities of nonresponse and postal response were statistically significant: 2.7 (95% CI: 1.9-3.9) and 1.6 (95% CI: 1.0-2.5), respectively. The same holds for the ORs for non-Dutch versus Dutch and low versus high maternal education for nonresponse: 2.0 (95% CI: 1.3-3.2) and 3.7 (95% CI: 2.0-6.7), respectively. Special education and severe handicap showed a statistically significant influence on nonresponse (OR: 1.6; 95% CI: 1.1-2.4 and OR: 2.6; 95% CI: 1.3-5.2) and postal response (OR: 2.0; 95% CI: 1.2-3.3 and OR: 4.4; 95% CI: 2.0-9.9), respectively. At the age of 19 years, primary school and special education were found significantly more frequent in the postal responders than in the full-response group (20% and 21% vs 6% and 12%). The full responders, on the other hand, were higher educated than were the postal responders. CONCLUSIONS: In this follow-up study at the age of 19 years, boys, non-Dutch adolescents, and low maternal education were overrepresented in the nonresponse and postal-response groups. Nonresponse decreased the proportion of infants with adverse outcome in assessed children. To be able to present reliable results for the total group of survivors in long-term follow-up studies, the nonresponse bias needs to be quantified. Therefore, it is evident that more research using statistical methods such as imputation of missing data is needed.

Is attrition bias a problem in neonatal follow-up?

AIM: To assess whether attrition rate influences outcome in the follow-up of very preterm infants. STUDY DESIGN: In a national follow-up study of infants born alive in 1983 in the Netherlands with a gestational age less than 32 weeks and/or a birth weight less than 1500 g, outcome was assessed separately for adolescents who responded early or late to a follow-up invitation at age 14 years. Neonatal data and outcome results of earlier assessments from early and late responders were compared to those of non-responders by univariate and nominal (polytomous logistic) regression analysis. SUBJECTS: There were 723 (76%) early responders, 130 (14%) late responders and 109 (11%) non-responders. RESULTS: We found significantly more non-Dutch origin and more disabilities and school problems at age 10 years in late- and especially in non-responders. At age 14 years, the health utility index was significantly lower in late responders compared to early responders. School outcome did not show difference in relation to the response groups. CONCLUSION: The results suggest that the incidence of adverse outcome in very preterm infants is underestimated when follow-up is incomplete and hence response rate is not a negligible problem in the assessment of late outcome. Therefore, follow-up studies should include a drop-out analysis to enable comparison to other studies.

Psychosocial problems among immigrant and non-immigrant children--ethnicity plays a role in their occurrence and identification.

BACKGROUND: This study aims to examine a) the prevalence of psychosocial problems and b) the association between parent-reported problems and the identification by doctors and nurses (child health professionals, CHP) working in preventive child health care, among immigrant and non-immigrant children. METHODS: CHPs examined 4,098 children aged 5 through 15 years (response: 90.1%) and interviewed parents and children during their routine health assessments in 19 Child Healthcare Services across the Netherlands, serving nearly all school-aged children routinely. The Child Behavior Checklist (CBCL) was completed by the parents. We compared five ethnic groups: indigenous Dutch, economic immigrants, immigrants from (former) Dutch colonies, from other non-industrialised, and from other industrialised countries. RESULTS: The prevalence of parent-reported problems on the CBCL is higher among children from former Dutch colonies and economic immigrant children than among indigenous children, especially regarding internalizing problems (odds ratios (OR); 95% confidence interval: 1.84; 1.03 to 3.29, and 2.52; 1.46 to 4.34). CHPs identified more problems among economic immigrant children (OR: 1.62; 1.01 to 2.60). Regarding associations, rates of CHP-identified problems were higher among indigenous children with clinical compared with normal CBCL Total Problems scores (OR: 6.90; 5.27 to 9.03), but not among economic immigrant children (OR: 0.73; 0.16 to 3.21). CONCLUSIONS: Psychosocial problems occur more frequently among some immigrant groups. CHP identification of psychosocial problems is poorly associated with parent report regarding economic immigrant children. This needs to be improved in order to provide better care.

Nationwide age references for sitting height, leg length, and sitting height/height ratio, and their diagnostic value for disproportionate growth disorders.

AIMS: To obtain age references for sitting height (SH), leg length (LL), and SH/H ratio in the Netherlands; to evaluate how SH standard deviation score (SDS), LL SDS, SH/H SDS, and SH/LL SDS are related to height SDS; and to study the usefulness of height corrected SH/H cut-off lines to detect Marfan syndrome and hypochondroplasia. METHODS: Cross-sectional data on height and sitting height were collected from 14,500 children of Dutch origin in the age range 0-21 years. Reference SD charts were constructed by the LMS method. Correlations were analysed in three age groups. SH/H data from patients with Marfan syndrome and genetically confirmed hypochondroplasia were compared with height corrected SH/H references. RESULTS: A positive association was observed between H SDS, SH SDS, and LL SDS in all age groups. There was a negative correlation between SH/H SDS and height SDS. In short children with a height SDS <-2 SDS, a cut-off limit of +2.5 SD leads to a more acceptable percentage of false positive results. In exceptionally tall children, a cut-off limit of -2.2 SDS can be used. Alternatively, a nomogram of SH/H SDS versus H SDS can be helpful. The sensitivity of the height corrected cut-off lines for hypochondroplasia was 80% and for Marfan syndrome only 30%. CONCLUSIONS: In exceptionally short or tall children, the dependency of the SH/H ratio (SDS) on height SDS has to be taken into consideration in the evaluation of body proportions. The sensitivity of the cut-off lines for hypochondroplasia is fair.

Bullying: who does what, when and where? Involvement of children, teachers and parents in bullying behavior.

Bullying victimization is associated with several health issues. Prevention of bullying is therefore an important goal for health and education professionals. In the present study, 2766 children from 32 Dutch elementary schools participated by completing a questionnaire on bullying behavior, and the involvement of teachers, parents and classmates in bullying incidents. The results of this study show that bullying is still prevalent in Dutch schools. More than 16% of the children aged 9-11 years reported being bullied on a regular basis and 5.5% reported regular active bullying during the current school term. Almost half of the bullied children did not tell their teacher that they were being bullied. When teachers knew about the bullying, they often tried to stop it, but in many cases the bullying stayed the same or even got worse. With regard to active bullying, neither the majority of the teachers nor parents talked to the bullies about their behavior. Our results stress the importance of regular communication between children, parents, teachers and health care professionals with regard to bullying incidents. In addition, teachers need to learn effective ways to deal with bullying incidents. Schools need to adopt a whole-school approach with their anti-bullying interventions.

[Prevalence of parental behaviour to diminish the crying of infants that may lead to abuse]. / Prevalentie van gedragingen van ouders om het huilen van zuigelingen te verminderen die kunnen leiden tot mishandeling.

OBJECTIVE: To estimate the prevalence of parental actions to stop infant crying that may threaten infant health, and to determine specific risk groups regarding these actions. DESIGN: Descriptive. METHOD: Before their visit to a well-baby clinic in the Netherlands, parents of 3345 infants aged 1-6 months (96.5% response) filled out an anonymous questionnaire on actions that they undertook to stop their child crying. RESULTS: At 6 months, 5.6% (95% confidence interval: 4.2-7.0%) of all the parents reported having smothered, slapped, or shaken their infant at least once because of its crying. The highest risks for detrimental parental actions were run by infants of parents from non-industrialised countries, of parents with no or only a part-time job, and of parents who had judged their infant's crying as excessive. CONCLUSION: Clinicians should be aware of the observed risk factors for abuse of young children known to cry a lot, in order to help parents to cope with this crying.

Height, weight, body mass index and pubertal development references for children of Moroccan origin in The Netherlands.

AIM: To provide growth and sexual maturation reference data for Moroccan children living in The Netherlands and to compare them with the reference data of children of Dutch origin. METHODS: Cross-sectional growth and demographic data were collected from 2880 children of Moroccan origin and 14,500 children of Dutch origin living in The Netherlands in the age range 0-20 y. Growth references for length, height, weight, weight-for-height, body mass index (BMI) and head circumference were constructed with the LMS method. Predictive variables for height and BMI were assessed by regression analyses. Reference curves for sexual maturation were estimated by a generalized additive model. RESULTS: Moroccan young adults were on average 9 cm shorter than their Dutch contemporaries. Mean final height was 174.7 cm for males and 161.3 cm for females. Height differences in comparison with Dutch children increase from 2 y onwards. Height SDS was predominantly associated with target height. Compared to Dutch children, maturation started 0.2 and 0.9 y later for girls and boys, respectively. Median age at menarche was 12.9 y, 3.6 mo earlier than in Dutch girls (p = 0.001). BMI of Moroccan children was above that of Dutch children, especially for girls. BMI SDS was associated with birthweight in the age group 0 - < or = 5 y. CONCLUSION: Moroccan children living in The Netherlands are substantially shorter than Dutch children. Girls have higher weight-for-height and BMI for age. Median age at menarche occurs earlier. Given these differences, separate growth charts for the Moroccan children are useful.

A cardiac-specific health-related quality of life module for young adults with congenital heart disease: development and validation.

This study represents the development and validation of a cardiac-specific module of the generic health-related quality of life (HRQoL) instrument, the TAAQOL (TNO/AZL Adult Quality Of Life), for young adults with congenital heart disease (CHD). Items were selected based on literature, an explorative previous study in CHD patients, interviews with patients, and the advice of experts. The newly developed Congenital Heart Disease-TNO/AZL Adult Quality of Life (CHD-TAAQOL) was tested in 156 patients with mild or complex CHD and consisted of three hypothesised subject scales: 'Symptoms' (9 items), 'Impact Cardiac Surveillance' (7 items), and 'Worries' (10 items). Cronbach's alpha for the three scales were 0.77, 0.78, and 0.82, respectively. Scale structure was confirmed by Principal Component Analysis, corrected item-scale and interscale correlations. Overall, 55% of reported health status problems were associated with negative emotions, which is an argument for assessing HRQoL as a concept distinct from health status. Convergent validity with validated generic instruments (TAAQOL and Short Form-36, SF-36) showed satisfactory coefficients. Discriminant validity was proven by significantly higher scores for mild CHD patients compared with those with complex CHD. In conclusion, the CHD-TAAQOL module together with the generic TAAQOL can be used to assess group differences for cardiac-specific HRQoL in young adults with CHD. Testing psychometric properties of the CHD-TAAQOL shows satisfactory results. However, to detect changes in HRQoL over time, further research is needed.

[Evaluation and validation of a perinatal death audit by means of feedback to the caregivers]. / Evaluatie en validatie van perinatale-sterfte-audit door terugkoppeling naar zorgverleners.

OBJECTIVE: To evaluate a perinatal audit procedure by communicating the results to the caregivers (midwives and obstetricians) involved, in order to determine whether the audit led to specific suggestions for improving practice and whether evaluation of the panel assessments by caregivers leads to a different evaluation of the audit process. DESIGN: Descriptive evaluation study. METHOD: Because of privacy regulations, the results of a recently published audit concerning perinatal mortality were reported at an aggregated level. At their own request, two participating hospitals received panel assessment reports of their own cases. The audit procedure, the 77 panel assessments and the care provided were then evaluated during closed meetings with the caregivers affiliated to the respective hospitals. RESULTS: In two audited cases of mortality the caregivers judged the panel's assessments as being too light and as too severe in one other case (Cohen's kappa: 0.98). Detailed case description was considered essential to the audit procedure. While aggregated reporting of audit results provides a general understanding of substandard factors in the care provided, feedback of results on an individual practice level led to specific suggestions for improvement (in relation to medical aspects, patient-caregiver relationship and collaboration between caregivers). Lack of anonymity appeared not to be an issue for the caregivers. CONCLUSION: The feedback of perinatal audit results to the caregivers involved as well as discussion of these results led to specific starting points in the areas of collaboration, documentation and policymaking at both individual and institutional level.

Development and evaluation of a follow up assessment of preterm infants at 5 years of age.

BACKGROUND: Long term follow up shows a high frequency of developmental disturbances in preterm survivors of neonatal intensive care formerly considered non-disabled. AIMS: To develop and validate an assessment tool that can help paediatricians to identify before 6 years of age which survivors have developmental disturbances that may interfere with normal education and normal life. METHODS: A total of 431 very premature infants, mean gestational age 30.2 weeks, mean birth weight 1276 g, were studied at age 5 years. Children with severe handicaps were excluded. The percentage of children with a correctly identified developmental disturbance in the domains cognition, speech and language development, neuromotor development, and behaviour were determined. RESULTS: The follow up instrument classified 67% as optimal and 33% as at risk or abnormal. Of the children classified as at risk or abnormal, 60% had not been identified at earlier follow up assessments. The combined set of standardised tests identified a further 30% with mild motor, cognitive, or behavioural disturbances. The paediatrician's assessment had a specificity of 88% (95% CI 83-93%), a sensitivity of 48% (95% CI 42-58%), a positive predictive value of 85% (95% CI 78-91%), and a negative predictive value of 55% (95% CI 49-61%). CONCLUSIONS: Even after standardised and thorough assessment, paediatricians may overlook impairments for cognitive, motor, and behavioural development. Long term follow up studies that do not include detailed standardised tests for multiple domains, especially fine motor domain, may underestimate developmental problems.

Early detection of psychosocial problems in adolescents: how useful is the Dutch short indicative questionnaire (KIVPA)?

BACKGROUND: Psychosocial problems, such as behavioural, emotional, and educational problems, are highly prevalent among children and adolescents. Early treatment may reduce these problems, if accurately identified. Validated questionnaires may support identification. The aim of this study is to assess the psychometric qualities of such a questionnaire, the Short Indicative Questionnaire for Psychosocial problems among Adolescents (KIVPA,) and to determine whether it is suitable for and adds to the early detection of psychosocial problems among adolescents. METHODS: Data came from a national sample of 1,440 Dutch adolescents, using the KIVPA, the Child Behavior Checklist (CBCL), and the Youth Self-Report (YSR). Of these, 1,248 provided data on all questionnaires (77.8%). The scale structure of the KIVPA was assessed; its sensitivity and specificity using CBCL, YSR and referral for psychosocial problems as criteria; and its contribution to detecting CBCL and YSR problems. RESULTS: The KIVPA is mostly uni-dimensional but the variance explained by its main factor is relatively low. The total KIVPA score discriminates between adolescents with and without problems on the three criteria. Using a clinical YSR total problem score as criterion, sensitivity and specificity are 0.82 and 0.85, respectively, at the proposed cut-off (area under the ROC curve: 0.92; 95% confidence interval (CI) 0.90-0.95). The odds ratio of a clinical YSR score for an elevated KIVPA score is 29.1 (95% CI: 14.4-59.1), although the KIVPA mainly covers internalizing problems. CONCLUSION: The KIVPA has added value in the early detection of internalizing psychosocial problems, but is not sufficiently efficient.

[Youth health care: much prevention for little money]. / Jeugdgezondheidszorg: veel preventie voor weinig geld.

As part of government policy, the 'Youth healthcare' prevention programme is offered free of charge to all children aged 0 to 19 years who are resident in the Netherlands. It consists of a programme of primary prevention (including vaccinations, information and advice) and secondary prevention (screening, surveillance, early diagnosis) and individual prevention and care. Many elements from the programme package have been shown to have a favourable cost-effectiveness relationship, in terms of health benefits and financially. Other elements have a social priority. The present government expenditure for the total youth healthcare package is about 380 million euros per year, that is 1900 euros per child. In terms of conditions prevented or years of life gained, this is cheaper than accepted prevention programmes for adults. The present approach can only be maintained and strengthened, if the expenditure is increased so that new programme elements can be investigated and--if found effective--implemented.

Women's interest in GP-initiated pre-conception counselling in The Netherlands.

BACKGROUND: Pre-conception counselling has the potential to reduce pregnancy complications and congenital disorders. The timing of counselling, before conception, is crucial to maximize the benefit. As many couples are unaware of their risk status and the fact that the first period of pregnancy is crucial, they do not seek information before pregnancy occurs. To reach couples with timely information, it seems that a health care worker needs to take the initiative. In The Netherlands, the GP is in an ideal position to offer pre-conception counselling. OBJECTIVE: The aim of this study was to determine the interest of women aged 18-40 in pre-conception counselling if this is offered to them by their own GP. METHOD: A cohort of women (n = 1206) received a personal letter from their own GP with an offer of pre-conception counselling. The women were requested to fill in a reply form, indicating if they were interested, might be interested (if they decided to become pregnant) or were not interested in an invitation for pre-conception counselling. When interested, they were asked to give an indication as to when they were planning a pregnancy. Women who were not interested were requested to give a reason. RESULTS: Almost 70% of the women returned the reply form. Up to the age of 29 years, at least 80% of the respondents were interested or might be interested should they decide to have children. Most women, especially the younger women, do not know exactly when they wish to become pregnant. Regardless of age, >70% of the respondents were interested. Only 11% of the respondents indicated specifically that they were not interested in advice. CONCLUSION: Women are interested in GP-initiated pre-conception counselling. Further research is needed to assess the effect of programmed and systematic pre-conception counselling, offered by GPs, on pregnancy outcome and the health of the children. A randomized controlled trial to assess these effects currently is being conducted at the Department of General Practice in Leiden.

Suboptimal care and perinatal mortality in ten European regions: methodology and evaluation of an international audit.

BACKGROUND: A European concerted action (the EuroNatal study) investigated differences in perinatal mortality between countries of Europe. This report describes the methods used in the EuroNatal international audit and discusses the validity of the results. METHODS: Perinatal deaths between 1993 and 1998 in regions of ten European countries were identified. The categories of death chosen for the study were singleton fetal deaths at 28 or more weeks of gestational age, all intrapartum deaths at 28 or more weeks of gestational age and neonatal deaths at 34 or more weeks of gestational age. Deaths with major congenital anomalies were excluded. An international audit panel used explicit criteria to review all cases, which were blinded for region. Subjective interpretation was used in cases of events or interventions where explicit criteria did not exist. Suboptimal factors were identified in the antenatal, intrapartum and neonatal periods, and classified as 'maternal/social', due to 'infrastructure/service organization', or due to 'professional care delivery'. The contribution of each suboptimal factor to the fatal outcome was listed and consensus was reached on a final grade using a procedure that included correspondence and plenary meetings. RESULTS: In all regions combined, 90% of all known or estimated cases in the selected categories were included in the audit. In total, 1619 cases of perinatal death were audited. Consensus was reached in 1543 (95%) cases. In 75% of all cases, the grade was based on explicit criteria. In the remaining cases, consensus was reached within subpanels without reference to predefined criteria. There was reasonable to good agreement between and within subpanels, and within panel members. CONCLUSIONS: The international audit procedure proved feasible and led to consistent results. The results that relate to suboptimal care will need to be studied in depth in order to reach conclusions about their implications for assessing the quality of perinatal care in the individual regions.
