A survey of an organization for families of patients with serious mental illness in The Netherlands.

OBJECTIVES: Members of Ypsilon, a Dutch family organization for relatives of patients with schizophrenia or chronic psychosis, were surveyed to determine whether patients whose families were involved in the organization were representative of all patients with schizophrenia in the Netherlands and whether Ypsilon was similar to family organizations in other countries, to learn about members' experience of the course of their relatives' illness, to determine the kinds of mental health care received by the patients, and to discern members' opinions of that care. METHODS: An extended version of the Involvement Evaluation Questionnaire, which measures consequences of psychiatric disorders for patients' relatives, was sent to a random sample of 1,000 Ypsilon members. The response rate was 70 percent. RESULTS: Members of Ypsilon are mainly older mothers of young male patients with a long history of schizophrenia. The patients as a group appeared to be more severely ill than the overall population of patients with schizophrenia in the Netherlands. Many respondents reported dissatisfaction with the quality of mental health care for their relative, particularly with their lack of access to treatment professionals, lack of information about their relative's illness, and lack of family involvement in treatment planning. CONCLUSIONS: Members of Ypsilon represent patients with severe mental illness who do not benefit sufficiently from treatment. Members want a greater role in treatment planning and more information and support from mental health care professionals. Members of Ypsilon and of family organizations in other countries have much in common, even though the extent of deinstitutionalization varies between countries.

Speech rate in a pluricentric language: a comparison between Dutch in Belgium and the Netherlands.

This paper investigates speech rate in two standard national varieties of Dutch on the basis of 160 15 mins conversations with native speakers who belong to four different regions in the Netherlands and four in the Dutch-speaking part of Belgium (Flanders). Speech rate was quantified as articulation rate and speaking rate, both expressed as the number of syllables per second (syll/s). The results show a significant effect of speakers' country of origin: subjects in the Netherlands speak 16% faster than subjects in Belgium (articulation: 5.05 vs. 4.23 syll/s, speaking: 4.23 vs. 4.00 syll/s). In addition, the independent variable sex was also found to be significant: on average, men speak 6% faster than women (articulation: 4.79 vs. 4.50 syll/s, speaking: 4.23 vs. 4.01 syll/s). The independent variable age was significant too: younger subjects speak 5% faster than older ones (articulation: 4.78 vs. 4.52 syll/s, speaking: 4.23 vs. 4.01 syll/s). The findings of this study confirm the traditional view that speech rate is determined by extralinguistic variables, but also suggest that there may be intrinsic tempo differences between language varieties.

Trends in dental caries in The Netherlands.

Until 1985, epidemiological studies in The Netherlands were focused on school-age children. Up to that year, few caries prevalence data for (young) adults in selected groups were available. In 1986, the first National Dental Survey of the adult population was carried out in The Netherlands. Lack of information made it impossible for trends in dental caries in adults to be studied on a scientific basis. However, with use of cross-sectional studies conducted on selected adult populations between 1970 and 1989, an indication of a trend in dental caries is described. Evident changes in the age-specific average DMFT scores took place in the younger age groups. In the older age groups, the average DMFT score has not changed. Changes in percentages of edentates in the period 1980-1990 probably reflect part of the changes in oral health status of Dutch adults.

AIDS in The Netherlands: the effects of several years of campaigning.

One of the primary aims of acquired immunodeficiency syndrome (AIDS) prevention campaigns in the Netherlands has been to inform the public of the facts about AIDS, thereby stimulating informed, but voluntary action to prevent transmission of the human immunodeficiency virus (HIV). By conducting successive population surveys from April 1987 until October 1989, the effects of this approach were assessed. Twice a year, approximately 1000 respondents, a random sample from the general population, were interviewed about AIDS and safe sex. Additionally, condom sales figures and STD incidences were evaluated. It appears that knowledge about the prevention of HIV transmission with condoms has reached 98% of the sample. During the study, there was an increase in the number of people who expressed an intention to use condoms or who already used them. Behaviour, however, appeared to fall short of intention. The observations were confirmed by condom sales figures and STD incidences. We conclude that the AIDS policy in the Netherlands has had beneficial effects, reflected by several indices.

An ethical perspective on euthanasia and assisted suicide in The Netherlands from a nursing point of view.

In the Netherlands, euthanasia and assisted suicide are formally forbidden by criminal law, but, under certain strictly formulated conditions, physicians are excused for administering these to patients on the basis of necessity. These conditions are bound up with a long process of criteria development. Therefore, physicians still live in uncertainty. Future court decisions may change the criteria. Apart from that, physicians can always be prosecuted. The position of nurses, however, is perfectly clear; they are never allowed to administer euthanasia or assisted suicide. Nevertheless, they should be involved in the decision-making process because they are an important source of information and have consultation skills. The openness of the discussion about these issues in the Netherlands may prevent an escalation of medical or nursing responsibility and falling victim to the 'slippery slope'.

Development of the role of the pediatric oncology nurse practitioner in the Netherlands.

The role of the nurse practitioner is rather new in the Netherlands. This is certainly applicable to the nurse practitioner in pediatric oncology (NPPO). Currently, 7 NPPOs are working in 4 different hospitals in the Netherlands. They all have relatively different roles within their own organization, which are dependent on the specific structure and culture of the organization. The NPPO role is not intended to fill a gap in medical care; rather, it is filling a gap in care for children and parents due to the shift of care to the home environment following early discharge. In the future, research will be necessary to ask children and parents about their experience with the NPPO.

Medication assistance: the development of drug surveillance and drug information in The Netherlands.

OBJECTIVE: To describe the development of drug surveillance and drug information in The Netherlands. DATA SYNTHESIS: Historically, the professions of medicine and pharmacy have existed separately with little contact between them. Since the 1960s, this situation has changed in The Netherlands. Both professions are cooperating to an ever-increasing degree, primarily in the areas of computerized drug surveillance and individualized patient drug information, resulting in greater patient benefit. CONCLUSIONS: Exchange of knowledge between physicians and pharmacists, greater cooperation among professionals, use of computerized patient medical records, and involvement of the patient in his own healthcare will have a positive influence on the development of drug assistance in the future.

Thirty years of hemophilia treatment in the Netherlands, 1972-2001.

Since the introduction of replacement therapy in the early 1960s by the infusion of plasma-derived factor VIII and IX preparations, important changes have occurred for hemophilia patients. We studied the medical and social developments over 30 years of hemophilia treatment. Since 1972, 5 cross-sectional national postal surveys among all hemophilia patients in the Netherlands were performed, the latest in 2001. The prestructured questionnaires included items on treatment, the presence of inhibitory antibodies against factor VIII or IX, the annual number of bleeding episodes, use of inpatient hospital care, and hepatitis C and HIV infections. Response rate in 2001 was 70%. Young patients (<16 years) with severe hemophilia showed the largest increase in use of prophylaxis, from 34% in 1972 to 86% in 2001. The occurrence of hemorrhages has gradually decreased. Hospital admissions decreased from 47% of all patients in 1972 to 18% in 2001. Our study shows that the treatment of patients with severe hemophilia in the Netherlands has focused on the use of prophylactic treatment, especially in children. This has resulted in a decrease in bleeding frequency and an improvement of the medical and social circumstances of patients.

Mortality among tuberculosis patients in The Netherlands in the period 1993-1995.

This study aimed to estimate excess mortality among tuberculosis patients in The Netherlands and identify risk factors for tuberculosis-associated mortality. The national tuberculosis register provided data on patients diagnosed in the period 1993-1995. Excess mortality in tuberculosis cases, according to age and sex, was determined by comparison with national mortality rates. Risk factors were identified and adjustment for confounders was carried out using Cox's proportional hazard analysis. Of 4,340 patients alive at diagnosis, 258 died within 1 yr while on treatment. The Kaplan-Meier survival probability after 1 yr was 93%. Tuberculosis patients had a standardized mortality ratio of 8.3. Independent risk factors for mortality were: gender; age; presence of a malignancy or human immunodeficiency virus (HIV) infection; addiction to alcohol or drugs; localization of tuberculosis; and the type of medical officer having made the diagnosis. Of all deaths, 83% occurred in two risk groups comprising 21% of tuberculosis patients: those aged > or =65 yrs and those having HIV infection or a malignancy. Tuberculosis patients in The Netherlands are at a considerably increased risk of death. However, the prognosis is very good for those aged less than 65 yrs and without human immunodeficiency virus infection or a malignancy.

Management of hypertension and hypercholesterolaemia in primary care in The Netherlands.

OBJECTIVE: Screening, treatment and monitoring guidelines for hypertension and hypercholesterolaemia have been developed to assist physicians in providing evidence-based health care. We conducted a retrospective study to assess the management of patients with these single or combined conditions. RESEARCH DESIGN AND METHODS: This was a retrospective cohort study conducted using data from the Integrated Primary Care Information (IPCI) project based in The Netherlands. Management of hypertension and hypercholesterolaemia was assessed from 2000-2003 by measuring the numbers of patients screened for these conditions, treated pharmacologically and monitored for treatment success. RESULTS: Approximately 11%, 3% and 10% of participants were eligible for screening for hypertension alone, hypercholesterolaemia alone and both conditions, respectively. Blood pressure screening was high in patients eligible for both blood pressure and cholesterol screening (> 86%), whereas cholesterol screening was low (< 56%). Among patients newly identified with hypertension or hypercholesterolaemia who were eligible for pharmacotherapy, 29% and 43% respectively were not treated within one year of diagnosis. Undertreatment was significantly lower in patients with both conditions (24% and 37% for antihypertensive and lipid-lowering treatment, respectively and 28% were not treated for both). Among newly treated patients, in the first year of treatment there was no record of a blood pressure or cholesterol assessment, for 35% and 72%, respectively. CONCLUSION: Management was sub-optimal in patients with hypertension or hypercholesterolaemia as well as in those with both of these conditions. The results of this study are likely to be widely applicable, particularly to other European and industrialised countries that have similar free-access health care systems to The Netherlands.

Population prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in the Netherlands. Should asymptomatic persons be tested during population-based Chlamydia screening also for gonorrhoea or only if chlamydial infection is found?

BACKGROUND: Screening and active case finding for Chlamydia trachomatis (CT) is recommended to prevent reproductive morbidity. However insight in community prevalence of gonococcal infections and co-infections with Neisseria gonorrhoea (NG) is lacking. METHODS: Nested study within a large population-based Chlamydia Screening Pilot among 21.000 persons 15-29 year. All CT-positive (166) and a random sample of 605 CT-negative specimens were as well tested for gonococcal infection. RESULTS: Overall Chlamydia prevalence in the Pilot was 2.0% (95% CI: 1.7-2.3), highest in very urban settings (3.2%; 95% CI: 2.4-4.0) and dependent of several risk factors. Four gonococcal infections were found among 166 participants with CT infection (4/166 = 2.4%; 95% CI: 0.1%-4.7%). All four had several risk factors and reported symptoms. Among 605 CT-negative persons, no infection with NG could be confirmed. CONCLUSION: A low rate of co-infections and a very low community prevalence of gonococcal infections were found in this population based screening programme among young adults in the Netherlands. Population screening for asymptomatic gonococcal infections is not indicated in the Netherlands. Although co-infection with gonorrhoea among CT-positives is dependent on symptoms and well-known algorithms for elevated risks, we advise to test all CT-positives also for NG, whether symptomatic or asymptomatic.

Health and health care utilisation among asylum seekers and refugees in the Netherlands: design of a study.

BACKGROUND: This article discusses the design of a study on the prevalence of health problems (both physical and mental) and the utilisation of health care services among asylum seekers and refugees in the Netherlands, including factors that may be related to their health and their utilisation of these services. METHODS/DESIGN: The study will include random samples of adult asylum seekers and refugees from Afghanistan, Iran and Somali (total planned sample of 600), as these are among the largest groups within the reception centres and municipalities in the Netherlands. The questionnaire that will be used will include questions on physical health (chronic and acute diseases and somatization), mental health (Hopkins Symptoms Checklist-25 and Harvard Trauma Questionnaire), utilisation of health care services, pre- and post-migratory traumatic experiences, life-style, acculturation, social support and socio-demographic background. The questionnaire has gone through a translation process (translation and back-translation, several checks and a pilot-study) and cross-cultural adaptation. Respondents will be interviewed by bilingual and bicultural interviewers who will be specifically trained for this purpose. This article discusses the selection of the study population, the chosen outcome measures, the translation and cross-cultural adaptation of the measurement instrument, the training of the interviewers and the practical execution of the study. The information provided may be useful for other researchers in this relatively new field of epidemiological research among various groups of asylum seekers and refugees.

Determinants of daily smoking in Turkish young adults in the Netherlands.

BACKGROUND: As little is known about the determinants of smoking in large ethnic minorities in the Netherlands and other Western European countries, we studied the determinants of smoking young adult offspring of Turkish migrants to the Netherlands. METHODS: Cross-sectional survey of 439 Turkish adults (18-28 y) in 2003. Smokers were compared with never smokers for five groups of determinants: demographic and socioeconomic factors, behavioral and emotional problems, psychosocial factors, and cultural factors. Associations were measured by prevalence rate ratios. RESULTS: Prevalences for men were 51% for daily smoking, 12% for former smoking, and 38% for never smoking. For women they were 44%, 11%, and 47%, respectively. Without adjustment for other determinants, higher prevalence was associated with: emotional problems, boredom, life events, and being male; and, specifically among women, with low self-esteem and having children. The strongest determinants of daily smoking In multivariate models were alcohol use and demographic and socio-economic factors. Of the cultural factors only strong Muslim identification was associated with lower smoking prevalence. CONCLUSION: The high prevalence of smoking warrants action. Many of the well-known determinants of smoking in Western countries were also important among young adults from ethnic minorities. Women with children and people of a low educational level deserve special attention.

Patient satisfaction with out-of-hours primary care in the Netherlands.

BACKGROUND: In recent years out-of-hours primary care in the Netherlands has changed from practice-based to large-scale cooperatives. The purpose of this study is to determine patient satisfaction with current out-of-hours care organised in general practitioner (GP) cooperatives, and gain insight in factors associated with this satisfaction. METHODS: From March to June 2003, 2805 questionnaires were sent to patients within three weeks after they had contacted the GP cooperative in their region. The study was conducted in the province of Limburg in the South of the Netherlands. One-third of these questionnaires was sent to patients who had only received telephone advice, one-third to patients who attended the GP cooperative for consultation, and one-third to patients who received a home visit. Four weeks after the first reminder, a non-respondents telephone interview was performed among a random sample of 100 patients. Analyses were performed with respect to the type of consultation. RESULTS: The total response was 42.4% (1160/2733). Sixty-seven percent of patients who received telephone advice only reported to be satisfied with out-of-hours care. About 80% of patients who went to the GP cooperative for consultation or those receiving a home visit, reported to be satisfied. Factors that were strongly associated with overall satisfaction included, the doctor's assistant's attitude on the phone, opinion on GP's treatment, and waiting time. CONCLUSION: Patients seem generally satisfied with out-of-hours primary care as organised in GP cooperatives. However, patients who received telephone advice only are less satisfied compared to those who attended the GP cooperative or those who received a home visit.

Emergency psychiatry, compulsory admissions and clinical presentation among immigrants to the Netherlands.

BACKGROUND: Black individuals in the UK have higher rates of contact with psychiatric emergency services than their White counterparts. It is unknown whether this is also the case in other European countries. AIMS: To compare the risk of contact with psychiatric emergency services and of compulsory admission between immigrant groups to The Netherlands and Dutch natives, and to determine the unique contribution of ethnicity to compulsory admission. METHOD: Study of 720 people referred to emergency psychiatric services in Greater Rotterdam, The Netherlands. RESULTS: The relative risks (RRs) for contacts with psychiatric emergency services, for having a psychotic disorder and for compulsory admission were significantly higher in most immigrant groups. Moroccans, Surinamese and Dutch Antilleans had the highest risks of compulsory admission. After controlling for symptom severity, danger, motivation for treatment and level of social functioning, non-Western origin was no longer associated with compulsory admission. CONCLUSIONS: Non-Western immigrant groups were overrepresented in psychiatric emergency care and were admitted compulsorily more frequently, possibly owing to a different clinical presentation.

Continuing positive secular growth change in The Netherlands 1955-1997.

Since 1858, an increase of mean stature has been observed in the Netherlands, reflecting the improving nutritional, hygienic, and health status of the population. In this study, stature, weight, and pubertal development of Dutch youth, derived from four consecutive nationwide cross-sectional growth studies during the past 42 y, are compared to assess the size and rate of the secular growth change. Data on length, height, weight, head circumference, sexual maturation, and demographics of 14,500 boys and girls of Dutch origin in the age range 0-20 y were collected in 1996 and 1997. Growth references for height and weight were constructed with a method that summarizes the distribution by three smooth curves representing skewness (L curve), the median (M curve), and coefficient of variation (S curve). The relationship between height and demographic variables was assessed by multivariate analysis. Reference curves for menarche and secondary sex characteristics were estimated by a generalized additive model using a logit transformation. A positive secular growth change has been present in the past 42 y for children, adolescents, and young adults of Dutch origin, although at a slower rate in the last 17 y. Height differences according to region, educational level of child and parents, and family size have remained. In girls, median age at menarche has decreased by 6 mo during the past four decades to 13.15 y. Environmental conditions have been favorable for many decades in the Netherlands, and the positive secular change in height has not yet come to a halt, in contrast to Scandinavian countries. Main contributors to the increase in height may be improved nutrition, child health, and hygiene, and a reduction of family size.

Pubertal development in The Netherlands 1965-1997.

We investigated pubertal development of 4019 boys and 3562 girls >8 y of age participating in a cross-sectional survey in The Netherlands and compared the results with those of two previous surveys. Reference curves for all pubertal stages were constructed. The 50th percentile of Tanner breast stage 2 was 10.7 y, and 50% of the boys had reached a testicular volume of 4 mL at 11.5 y of age. Median age at menarche was 13.15 y. The median age at which the various stages of pubertal development were observed has stabilized since 1980. The increase of the age at stage G2 between 1965 and 1997 is probably owing to different interpretations of its definition. The current age limits for the definition of precocious are close to the third percentile of these references. A high agreement was found between the pubic hair stages and stages of pubertal (genital and breast) development, but slightly more in boys than in girls. Menarcheal age was dependent on height, weight, and body mass index. At a given age tall or heavy girls have a higher probability of having menarche compared with short or thin girls. A body weight exceeding 60 kg (+1 SDS), or a body mass index of >20 (+1 SDS), has no or little effect on the chance of having menarche, whereas for height such a ceiling effect was not observed. In conclusion, in The Netherlands the age at onset of puberty or menarche has stabilized since 1980. Height, weight, and body mass index have a strong influence on the chance of menarche.

Spinocerebellar ataxias in the Netherlands: prevalence and age at onset variance analysis.

BACKGROUND: International prevalence estimates of autosomal dominant cerebellar ataxias (ADCA) vary from 0.3 to 2.0 per 100,000. The prevalence of ADCA in the Netherlands is unknown. Fifteen genetic loci have been identified (SCA-1-8, SCA-10-14, SCA-16, and SCA-17) and nine of the corresponding genes have been cloned. In SCA-1, SCA2, SCA3, SCA6, SCA7, SCA-12 and SCA-17 the mutation has been shown to be an expanded CAG repeat. Previously, the length of the CAG repeat was found to account for 50 to 80% of variance in age at onset. Because of heterogeneity in encoded proteins, different pathophysiologic mechanisms leading to neurodegeneration could be involved. The relationship between CAG repeat length and age at onset would then differ accordingly. METHOD: Based on the results of SCA mutation analysis in the three DNA diagnostic laboratories that serve the entire Dutch population, the authors surveyed the number of families and affected individuals per SCA gene, as well as individual repeat length and age at onset. Regression analysis was applied to study the relationship between CAG repeat length and age at onset per SCA gene. The slopes of the different regression curves were compared. RESULTS: On November 1, 2000, mutations were found in 145 ADCA families and 391 affected individuals were identified. The authors extrapolated a minimal prevalence of 3.0 per 100,000 (range 2.8 to 3.8/100,000). SCA3 was the most frequent mutation. CAG repeat length contributed to 52 to 76% of age at onset variance. Regression curve slopes for SCA-1, SCA2, SCA3, and SCA7 did not differ significantly. CONCLUSIONS: The estimated minimal prevalence of ADCA in the Netherlands is 3.0 per 100,000 inhabitants. Except for SCA6, the relationship between age at onset and CAG repeat expansion does not differ significantly between SCA-1, SCA2, SCA3, and SCA7 patient groups in our population, indicating that these SCA subtypes share similar mechanisms of polyglutamine-induced neurotoxicity, despite heterogeneity in gene products.
