[Secondary cases of meningococcal disease in The Netherlands, 1989-1990; a reappraisal of chemoprophylaxis].

OBJECTIVE: To assess the secondary attack rate (SAR) of meningococcal disease among the household contacts of primary patients and to describe the use of chemoprophylaxis in the Netherlands. DESIGN: Descriptive, nation-wide survey. METHODS: Information was collected of patients with meningococcal disease, reported between April 1st, 1989 and April 30th, 1990, and their household contacts. A household contact suffering from meningococcal disease between 24 hours and 1 month after hospital admission of the primary patient, was considered to be a secondary case. Chemoprophylaxis was considered appropriate if rifampicin or minocycline had been prescribed to all household contacts within a maximum of one day after admission of the primary patient. RESULTS: There were 5 secondary cases (SAR: 0.3%). Chemoprophylaxis was prescribed to 627 of 1130 household contacts (55%). Of those the prophylaxis was considered appropriate in 46%. 2 secondary cases were not given any prophylaxis, 2 received penicillin and 1 rifampicin. Of the primary patients, 6% were given prophylaxis during their hospital stay. All meningococci, isolated from pairs of secondary and primary patients, were rifampicin sensitive. CONCLUSIONS: The SAR of meningococcal disease in the Netherlands is similar to that in other countries. Although prescription of chemoprophylaxis is not recommended by the government, it is prescribed to 55% of the household contacts, and in almost half of these instances it was considered to be appropriate. Chemoprophylaxis is rarely prescribed to primary patients. Recommendations concerning chemoprophylaxis in the Netherlands are in need of reappraisal. Based on the results from this study and the literature, the prescription of chemoprophylaxis to all household contacts of a patient with meningococcal disease, and to the index patient, is recommended.

Schizophrenia in Surinamese and Dutch Antillean immigrants to The Netherlands: evidence of an increased incidence.

BACKGROUND: Reports of an increased incidence of schizophrenia in Afro-Caribbean immigrants to the UK are a matter of much debate. It is of interest, therefore, that in the 1970s and 1980s many immigrants from Surinam and The Netherlands Antilles have settled in The Netherlands. The purpose of our study was to compare the risk of a first admission for schizophrenia for Surinamese- and Antillean-born persons aged 15-39 years to that for their Dutch-born peers in the period 1983-1992. METHODS: We used data from the Dutch psychiatric registry. Age-adjusted relative risks were calculated using Poisson regression analysis. RESULTS: The risk for the immigrants was found to be three to four times higher than that for the Dutch-born. Age-adjusted relative risks were significantly higher for male than for female immigrants. CONCLUSIONS: The results provide evidence of an increased incidence in these immigrant groups and support similar findings on Afro-Caribbeans in the UK. Migration from Surinam was on such a large scale that selective migration of persons at risk for the disorder is unlikely to account entirely for these findings.

Ethnic differences in total and cause-specific infant mortality in The Netherlands.

We examined ethnic differences in infant mortality and the contribution of several explanatory variables. Data of Statistics Netherlands from 1995 to 2000 were studied (1,178,949 live borns). Proportional hazard analysis was used to show ethnic differences in total and cause-specific infant mortality. Obstetric, demographic and -geographical variables, and socio-economic status were considered as possible determinants. The four major ethnic minority groups showed an elevated risk of infant mortality, ranging from 1.28 in Turkish infants to 1.50 in Antillean/Aruban infants. In the early neonatal period, risks were elevated for Surinamese (hazard ratio [HR] 1.48, 95% confidence intervals [CI] 1.23, 1.78) and Antilleans/Arubans (HR 1.43, 95% CI 1.06, 1.92). In the post-neonatal period, risks were only elevated for Turkish (HR 2.20, 95% CI 1.80, 2.69) and Moroccan infants (HR 2.06, 95% CI 1.67, 2.55). Surinamese and Antillean/Aruban infants had an elevated risk of dying from perinatal causes (HR 1.62, 95% CI 1.33, 1.98 and 1.69, 95% CI 1.24, 2.29 respectively), Turkish and Moroccan infants had an elevated risk of dying from congenital anomalies (HR 1.42, 95% CI 1.16, 1.73 and 1.46, 95% CI 1.20, 1.79 respectively). Inequalities as a result of socio-economic position and demographic factors, such as marital status and maternal age, partially explain the ethnic differences in infant mortality. We conclude that ethnic minority groups in The Netherlands have a higher infant mortality than the native population, which in part seems preventable by reducing inequalities in socio-economic status. Marital status and age of the mother are important other risk factors of infant mortality.

Perinatal mortality in a first generation immigrant population and its relation to unemployment in The Netherlands.

STUDY OBJECTIVE: To consider the association between biological and social risk factors and perinatal mortality in an ethnically mixed population in Amsterdam, The Netherlands. DESIGN: This was a matched case-control study. Cases included all registered stillborn infants and all registered liveborn infants who died within seven days of birth. Controls were selected from infants remaining alive. Each case was matched with two controls by date of registration. SETTING: Civil registry of births and deaths, Amsterdam, The Netherlands, 1975-80. PATIENTS: All 666 babies who died in the perinatal period and 1332 controls selected from the liveborn survivors. OUTCOME: Perinatal mortality. MAIN RESULTS: Perinatal mortality was independently associated with the father's and mother's employment status, maternal age, parity, and infant sex, but not with the father's or mother's country of birth. CONCLUSIONS: Employment status and not country of birth should be the main focus in studies of perinatal mortality in this population of mixed ethnicity. Future studies on selected behavioural, socio-economic, and cultural factors are needed to provide a better understanding of the causes of increased perinatal mortality among families in which the parents are unemployed.

Epidemiology of bacterial endocarditis in The Netherlands. I. Patient characteristics.

BACKGROUND: Studies of the epidemiology of bacterial endocarditis are usually based on a retrospective review of medical records from referral centers serving diverse patient populations. These studies are therefore likely to suffer from selection bias. We conducted a nationwide prospective epidemiologic study of endocarditis in the Netherlands. METHODS: During a 2-year period, all cases of consecutively hospitalized patients with suspected endocarditis in the Netherlands were reported to us. While hospitalized, patients were visited for an in-person interview and a review of the medical record. RESULTS: Of 559 episodes, 438 met the criteria for endocarditis; these included 89 episodes of prosthetic valve endocarditis and 349 episodes of native valve endocarditis. Adjusted for age- and sex-specific population figures, the incidence was 19 per million person-years. The incidence increased significantly with age, and men were more often affected than women (266 and 172 cases, respectively). Rheumatic and congenital cardiac lesions formed most of the underlying heart diseases. Mitral valve prolapse was present in only 29 patients with native valve endocarditis (8.3%). A history of intravenous drug abuse was present in 32 patients (7.3%). Viridans streptococci, staphylococci, and enterococci together constituted 86% of the isolated bacterial strains. Only 1.1% of the patients had culture-negative endocarditis. Overall case fatality was 19.7% and varied widely according to causative microorganism. CONCLUSION: The distribution of causal microorganisms, the case fatality rate, and the incidence rate of endocarditis are age related. Therefore, a meaningful comparison of data is only possible between population-based cohorts of patients with endocarditis.

Attitudes and practices concerning the end of life: a comparison between physicians from the United States and from The Netherlands.

BACKGROUND: This study compares attitudes and practices concerning the end-of-life decisions between physicians in the United States and in the Netherlands, using the same set of questions. METHODS: A total of 152 physicians from Oregon and 67 from the Netherlands were interviewed using the same questions about (1) their attitudes toward increasing morphine with premature death as a likely consequence, physician-assisted suicide (PAS), and euthanasia; and (2) their involvement in cases of euthanasia, PAS, or the ending of life without an explicit request from the patient. Odds ratios, with 95% confidence intervals, were calculated to investigate relation between attitudes and various characteristics of the respondents. RESULTS: American physicians found euthanasia less often acceptable than the Dutch, but there was similarity in attitudes concerning increasing morphine and PAS. American physicians found increasing morphine and PAS more often acceptable in cases where patients were concerned about becoming a burden to their family. There was a discrepancy between the attitudes and practices of Dutch physicians concerning PAS. The proportions of physicians having practiced euthanasia, PAS, or ending of life without an explicit request from the patient differ more between the countries than do their attitudes, with American physicians having been involved in these practices less often than the Dutch. CONCLUSIONS: In this study of American and Dutch physicians, 2 important differences emerge: different attitudes toward the patient who is concerned over being a burden, and different frequency of euthanasia and PAS in the two countries.

Income differences in persons seeking outpatient treatment for mental disorders: a comparison of the United States with Ontario and The Netherlands.

BACKGROUND: Variations in the relationships among income, use of mental health services, and sector of care are examined by comparing data from 3 countries that differ in the organization and financing of mental health services. METHODS: Data come from the 1990-1992 National Comorbidity Survey (n = 5,384), the 1990-1991 Mental Health Supplement to the Ontario Health Survey (n = 6,321), and the 1996 Netherlands Mental Health Survey and Incidence Study (n = 6031). Analysis of the association between income and use of mental health services was carried out for the population that was between ages 18 and 54 years. Differential use of mental health treatment was examined in 3 sectors: the general medical sector, the specialty sector, and the human services sector. RESULTS: No significant association between income and probability of any mental health treatment was observed for persons with psychiatric disorders in any of the 3 countries. However, there were significant differences among countries in the association between income and sector of mental health care treatment. In the United States, income is positively related to treatment being received in the specialty sector and negatively related to treatment being received in the human services sector. In the Netherlands, patients in the middle-income bracket are less likely to receive specialty care, while those in the high-income bracket are less likely to be seen in the human service sector. Income is unrelated to the sector of care for patients in Ontario. CONCLUSIONS: Future research should examine whether differential access to the specialty sector for low-income people in the United States is associated with worse mental health outcomes.

In-hospital mortality and disposition of diabetic amputees in The Netherlands.

The purpose of this study is to identify in-hospital mortality of diabetic amputees and the disposition of survivors in The Netherlands in 1991 and 1992. A database including all hospitalizations in The Netherlands was used. Amputees who died while in the hospital were analysed separately. Survivors were categorized according to different types of discharge: home, nursing home, rehabilitation facility, and other health care facilities. Overall 9.0% of diabetic amputees died while in hospital. The age-adjusted mortality incidence for the diabetic population was 36.3 per 1000 diabetic amputees (95% CI: 18.7-53.9) and 28.2 per 1,000 non-diabetic amputees (95% CI: 20.5-35.9). Non-diabetic amputees with PVD has proportionally more mortality than diabetic amputees with PVD (P < 0.01), diabetic amputees without PVD (P < 0.01), and non-diabetic amputees without PVD (P < 0.001). Using Cox regression analysis age (B(age) = 0.023, RR = 1.024) and the occurrence of multiple amputations during the hospitalization (Bmultiple = 0.325, RR = 1.383) were significant negative predictors for survival. As age and level of amputation increased, more diabetic and non-diabetic amputees were discharged to facilities other than home (P < 0.001).

Confirmation of high incidence of type 1 (insulin-dependent) diabetes mellitus in Moroccan children in The Netherlands.

The incidence of Type 1 (insulin-dependent) diabetes mellitus among Moroccan children aged (0-19 years) in The Netherlands was determined. Point of reference was the data derived from the second nationwide incidence study on Type 1 diabetes among children under 20 years of age. In that study the incidence among Dutch children was 13.2 100000(-1) year(-1). To scrutinize the data and to obtain more information a questionnaire was sent in 1993 to all specialists who had reported that they had diagnosed a patient with Type 1 diabetes during the years 1988-1990 whose parents originated from Morocco, Turkey or other foreign countries. The questionnaire requested information on origin and migration of child and parents. The response to the questionnaire was 86% for the Moroccan children, 75% for the Turkish children and 100% for the children from other countries. In only one case a wrong country had been recorded. None of the patients had been in The Netherlands for less than 6 months before the diagnosis. The incidence for Moroccan children was 20.0 (95% CI 14.6-26.9) and for Turkish children 4.5 (95% CI 2.2-8.0) 100,000(-1) year(-1). It is concluded that the incidence of Type 1 diabetes in Moroccan children (0-19 years) is 1.5 times higher than in Dutch children and 4.5 times higher than in Turkish children.

Trends in survival of prostate cancer in southeastern Netherlands, 1971-1989.

The increase in the incidence of prostate cancer observed over the past 2 decades is suggested to be largely due to increased detection of insignificant tumors. To explore this assumption, we investigated trends in survival of prostate cancer patients in southeastern Netherlands, an area with almost 1 million inhabitants, where the age-adjusted incidence of prostate cancer increased by 53% between 1971 and 1989, i.e., before the introduction of prostate-specific antigen testing. Survival was calculated for all patients registered in the Eindhoven Cancer Registry between 1971 and 1989 (n = 2,562). In spite of earlier diagnosis, survival barely changed during this time period. Five-year relative survival improved slightly from 53% [95% confidence interval (CI) 47%, 59%] in 1975-1979 to 56% (CI 51%, 61%) in 1985-1989. Stratified analyses suggested an improvement since 1980 for patients below 75 years with localized tumors but, despite possible stage migration, decreased survival for those with metastasized and/or poorly differentiated tumors. Patients below 75 years whose tumors were diagnosed unexpectedly during transurethral resection of the prostate (TURP) exhibited a relative survival of 85% 5 years and 68% 10 years after diagnosis. Less extensive application of TURP in The Netherlands might explain why our findings do not agree with those in Sweden and the United States. Inference from country-specific trends in survival appears not to be necessarily generalizable to other countries with a similar increase in the incidence of prostate cancer. We conclude from our results that earlier diagnosis of prostate cancer between 1971 and 1989 may be accompanied by an increased incidence of an aggressive variant.

Glucocerebrosidase genotype of Gaucher patients in The Netherlands: limitations in prognostic value.

Gaucher disease is a recessively inherited lysosomal storage disorder that is caused by a deficiency in glucocerebrosidase activity. The clinical expression is markedly heterogeneous with respect to age of onset, progression, severity, and neurological involvement. The relative incidence of glucocerebrosidase (GC) mutations has been studied extensively for Jewish but not for non-Jewish Caucasian patient populations. The present survey on mutant GC genotypes prevalent in Gaucher disease in The Netherlands was taken of 72 patients from different genetic backgrounds. This number is more than half the total number of affected Gaucher patients to be expected on the basis of the incidence of the disorder in this country. Analysis of nine GC mutations led to the identification of 74% of the mutant GC alleles in patients from 44 unrelated Dutch families (i.e., families that have lived in The Netherlands for at least several generations) and of 44% of the mutant GC alleles in patients from nine unrelated families that recently immigrated from both European and non-European countries. The N370S (cDNA 1226G) GC mutation proved to occur most frequently (41%) in the unrelated Dutch patients and less frequently (6%) in the unrelated immigrant patients and was always associated with the nonneuronopathic (Type 1) form of the disease. Apart from the association of the N370S mutation with Type 1 Gaucher disease, the prognostic value of GC genotyping was limited, since a particular GC genotype did not correlate closely to a specific clinical course, or to a specific relative responsiveness to enzyme-supplementation therapy.

Feasibility of mobile provision of health services: a study of child monitoring centres in The Netherlands.

In the Netherlands children up to the age of 4 years are regularly monitored. Several demographic and economic developments have led to the idea of using mobile child monitoring centres. Mobile units are expected to be flexible, effective and efficient but little information is available about the implications for the organization, the clients and other third parties involved. This paper outlines an approach for assessing the feasibility of mobile child monitoring centres. The focus is on the area Midden-Gelderland in the Netherlands and the implications of alternative options are compared on the basis of feasibility criteria or performance measures. The implementation of mobile units for child monitoring appears to be feasible with respect to most performance measures but there are also disadvantages. The approach taken proved to be a valuable exercise since it provided detailed information on all implications. It was decided that the mobile units would not be purchased but that some child monitoring centres could be closed without replacing them.

Clear cell adenocarcinoma of the vagina and cervix. A report of the Central Netherlands Registry with emphasis on early detection and prognosis.

The Central Netherlands Registry (CNR) of women with vaginal or cervical clear cell adenocarcinoma (CCAC) was established in 1985. An overview is presented of clinical and pathologic data of 55 patients who were registered at the CNR until July 1, 1988. All Netherlands Departments of Pathology (NDP) maintain a patient registry and 95% of the Institutes are connected with a Central Archive via a computer network. The histologic slides and clinical status were reviewed at the CNR. Twenty-five tumors were classified as vaginal carcinoma and 30 as cervical carcinoma. The mean age of the patients was 22 years. Fifty-five percent of patients (63% of patients with known maternal history) were exposed to diethylstilbestrol (DES) in utero. The majority of cases was initially diagnosed after 1980. Cytologic examination before the initial histologic diagnosis indicated that cervical tumors were detected in 80% of cases, but vaginal tumors were detected only in 33% of cases. It was concluded that an examination of DES-exposed women should consist of colposcopic inspection of the cervix and vagina, cytologic examination of the cervix and four quadrants of the vagina, and careful palpation of the cervix and the entire vaginal wall. The most important prognostic parameter for patients with CCAC was stage and grade of nuclear atypia. The results of a statistical analysis showed that these features were the most effective to distinguish between nonsurvivors and patients surviving more than 5 years.

The prevalence and manifestations of hereditary hemorrhagic telangiectasia in the Afro-Caribbean population of the Netherlands Antilles: a family screening.

Hereditary hemorrhagic telangiectasia (HHT) has been reported rarely in people of African descent. The prevalence in the Afro-Caribbean population of the Netherlands Antilles is suspected to be high. A family screening in this population was done to arrive at a point prevalence and to identify patients with pulmonary involvement. By clinical history and physical examination, 219 persons over age twelve with a first-degree relative with HHT were screened. The diagnosis was based on the new diagnostic criteria [Shovlin et al., 2000]. Chest-roentgenogram and pulse-oximetry or measurement of arterial oxygen pressure were used to detect pulmonary involvement. HHT was diagnosed in 112 individuals (51%), with at least a point prevalence of 1 in 1,331 inhabitants of Curaçao and Bonaire older than twelve years. The diagnosis was uncertain in 27; this was partly due to the new stringent criteria. Epistaxis was present in 98% and telangiectases in 99%. Facial telangiectases were relatively rare due to pigmented skin. Pulmonary involvement was found in 28% with serious-mainly neurological-complications in 48%. The point-prevalence of HHT in the Afro-Caribbean population of the Netherlands Antilles is the highest known in the world. Pulmonary involvement in this population is not rare and causes serious complications.

Laparoscopic cholecystectomy in The Netherlands.

Laparoscopic cholecystectomy was introduced into the Netherlands in the Spring of 1990. The aim of this study was to evaluate the results of the procedure in Dutch hospitals over the first 2 years to obtain some insight into its safety and efficacy in general surgical practice. A written questionnaire was sent to all 138 Dutch surgical institutions enquiring about conversion rate, complications (with emphasis on mortality rate and common bile duct injuries), operating time and hospital stay. The surgeons' opinions were also sought on possible contraindications such as previous operation, bile duct stones and cholecystitis, as were their estimations of the percentage of patients in their practice eligible for laparoscopic cholecystectomy. Data were obtained for 6076 laparoscopic cholecystectomies; the response rate was 100 per cent. Conversion to open cholecystectomy was necessary in 413 patients (6.8 per cent), mostly because of adhesions, cholecystitis, haemorrhage and unclear anatomy. Postoperative complications were reported in 260 patients (4.3 per cent). There were seven deaths (0.12 per cent) and 52 (0.86 per cent) bile duct injuries, of which 20 were recognized during laparoscopy. The mean operating time for the ten most recent patients in each institute was 70 (range 30-180) min and the mean hospital stay 4.5 (range 2-8) days. Previous lower abdominal operations were not considered to be a contraindication by 96 per cent of surgeons, whereas previous upper abdominal procedures were regarded as a contraindication by 66 per cent. After successful clearance of the bile duct at endoscopic retrograde cholangiopancreatography, only 12 per cent would perform an open procedure. Moderate cholecystitis was not considered a contraindication to laparoscopic cholecystectomy by 71 per cent of surgeons, but severe cholecystitis was a reason for open cholecystectomy for 83 per cent. In most surgical practices 70-80 per cent of patients were considered to be eligible for the laparoscopic procedure. In conclusion, laparoscopic cholecystectomy has gained rapid acceptance in the Netherlands. Although the number of bile duct injuries is high, the findings of this general survey are similar to those from highly specialized centres and match the overall results of conventional cholecystectomy.

Operative mortality after colorectal resection in the Netherlands.

BACKGROUND: The aim of this study was to quantify factors related to operative mortality after colorectal resection in the Netherlands. METHODS: Multilevel logistic regression modelling was used. Institutional effects were calculated with and without adjustment for specific patient (age, sex, urgency of operation) and hospital (number of procedures, type of hospital) characteristics. All adult Dutch patients who underwent primary colorectal resection between 1994 and 1999 were included, except those who had (sub)total colectomy or local rectal resection. RESULTS: A total of 67 594 patients underwent colorectal resection. The in-hospital mortality rate was 7.0 per cent (elective 3.9 per cent, acute 14.3 per cent). Acute operation (odds ratio 3.89) and age (odds ratios 2.63, 5.23 and 10.13 for patients aged 50-69, 70-79 and 80 or more years respectively compared with those aged less than 50 years) had the strongest effects, followed by male sex (odds ratio 1.48) and type of hospital. There was no difference in operative mortality rate between low-, medium- and high-volume hospitals. CONCLUSION: In the Netherlands, advanced age and acute operation are by far the most important factors related to operative mortality after colorectal resection. Male sex and type of hospital have only a modest effect, and there is no discernible effect of hospital volume.

Adults with learning disabilities: differences between The Netherlands and Flanders.

In this paper, similarities and differences are outlined between adults with self reported learning disabilities (SRLD) drawn from the International Adult Literacy Survey (IALS) data on adult literacy in The Netherlands and Flanders. These results are discussed in terms of striking differences in the educational context within which the adults developed. The literacy skills of SRLD adults in The Netherlands are superior to SRLD adults in Flanders. This is interpreted in terms of societal acceptance of disability.

Obstetric care in the Netherlands: manpower substitution and differential costs.

Trends in the Netherlands show an expanded role for obstetricians in hospital-based prenatal and natal care, as well as a shift in postnatal care away from hospitals to domiciliary care. While general practitioners attend a steadily declining share of total births, midwives continue to play a central role in supporting over 40 per cent of all births and in attending nearly two thirds of all home births, which, in the Netherlands, is the preferred option for more than a third of childbearing women. As shown in the figures, shifts of births into hospitals and of postnatal care out of hospitals produce opposite effects on obstetric expenditures. Cost differences are primarily associated with variation in location of care, and only secondarily with variation in provider of care, underscoring the importance of contrasting styles of obstetric management and their influence on costs. In the context of these observed transitions, the increasing popularity of policlinical deliveries constitutes a pivotal force whose impact to date appears to have been neglected by planners and health care decision makers.
