Shared help seeking behaviour within families: a retrospective cohort study.

OBJECTIVE: To examine the extent to which the family influences individual use of general practitioner care. DESIGN: Retrospective cohort study of all consultations in one calendar year. Multilevel modelling was used to analyse contact frequencies of individuals within families within practices. SETTING: General practice in the Netherlands. PARTICIPANTS: 42 262 families with children aged 2-21 years registered in 96 practices. MAIN OUTCOME MEASURES: Family influence on individual frequency of contact with general practice and correlation in frequency of contacts between parents and children. RESULTS: After correction for patients' age and sex, analysis of siblings indicates that 22% of the variance in frequencies of contact can be ascribed to influence of the family. This means that contact frequencies of family members within families resemble each other, whereas differences in contact frequencies exist between families. Almost 6% of the variance refers to differences between practices and 73% of the variance refers to individual differences. The strongest correlations were found between mothers and children and between children. CONCLUSIONS: The extent of shared help seeking behaviour within families has considerable implications in the context of the practice.

Monitoring health inequalities through general practice: the Second Dutch National Survey of General Practice.

BACKGROUND: For the second time a plan to monitor public health and health inequalities in the Netherlands through general practice was put into action: the Second National Survey of General Practice (DNSGP-2, 2001). The first aim of this paper is to describe the general design of DNSGP-2. Secondly, to describe self assessed health inequalities in the Netherlands. Thirdly, to present differences in prevalence of chronic conditions by educational attainment using both self-assessed health and medical records of GPs. Finally, inequalities in 1987 (DNSGP-1) and 2001 will be compared. METHODS: Data were collected from 96 (1987) and 104 (2001) general practices. The data include background information on patients collected via a census, approximately 12,000 health interview surveys per time point and more than one million recorded contacts of patients with their GPs in both years. The method of statistical analysis is logistic regression. RESULTS: The analyses shows that the lower educated have significantly higher odds of feeling unhealthy and having chronic conditions in 2001. Diabetes and myocardial infarction (GP data) showed the largest difference in prevalence between educational groups (OR 2.5 and 2.4, self-reported data). The way the data is collected (self-assessment versus GP registration) hardly affects the magnitude of the educational differences in the prevalence of chronic conditions. The pattern of health inequalities across chronic conditions in 1987 and 2001 hardly differs. Diabetes doubled in prevalence and health inequalities were not significant in 1987, but compared to the other conditions were largest in 2001 (OR 1.1 versus 2.5). CONCLUSION: Health inequalities were shown to be substantial in 2001 and persistent over time. Socio-economic differences were shown to be similar using self-assessed health data and GP data. Hence, a person's educational attainment did not appear to play a part in presenting health problems to the GP.

Vaccination of high-risk patients against influenza: impact on primary care contact rates during epidemics. Analysis of routinely collected data.

A general practice (GP) based retrospective cohort study was conducted to assess the effects of influenza vaccination on the primary care contact rate during influenza epidemics. Given the rising workload of family physicians, particularly due to ageing of the population, it is very relevant to know to whether influenza vaccination of high-risk patients reduces the contact rate during epidemics. No effect of vaccination was found on the contact rate of GP during a mild epidemic period. During a 'normal' influenza epidemic, the workload was reduced through fewer contacts by patients with cardiovascular or diabetic diseases. Epidemic periods severe enough to show contact rate reduction occurred approximately every other year.

Medical practice variations in hospital care; time trends of a spatial phenomenon.

A persistent finding in health services research is that health care delivery and hospital utilisation in the Western world varies widely between areas, both within and between countries. Most studies have concentrated on cross-sectional variations in medical practice. The aim of this article is to investigate whether or not small area variation changed through time. We used hospital discharge rates in the Netherlands for 12 diagnostic or surgical categories to indicate medical practice patterns. The data cover a time span of almost two decades: 1980-1997. First, it was found that in most cases regions are consistently above or below the national trend in the study period. Second, the analysis revealed a statistically significant decline of regional variation in hospital discharges in general during the 1980s and the 1990s. In all but one medical category the results of the separate analyses point towards a downward trend. In one-third of the medical categories this downward trend was statistically significant. Potential parallel changes in regional disparities in need for care, e.g. morbidity or age composition of regional populations or changes in regional differences in care supply are discussed.

Public trust in Dutch health care.

This article describes the development of a valid and reliable instrument to measure different dimensions of public trust in health care in the Netherlands. This instrument is needed because the concept was not well developed, or operationalized in earlier research. The new instrument will be used in a research project to monitor trust and to predict behaviour of people such as consulting "alternative practitioners". The idea for the research was suggested by economic research into public trust. In the study, a phased design was used to overcome the operationalization problem. In the first phase, a qualitative study was conducted; and, in the second, a quantitative study. In the first phase, more than 100 people were interviewed to gain insight into the issues they associated with trust. Eight categories of issues that were derived from the interviews were assumed to be possible dimensions of trust. On the basis of these eight categories and the interviews, a questionnaire was developed that was used in the second phase. In this phase, the questionnaire was sent to 1500 members of a consumer panel; the response was 70 percent. The analysis reveals that six of the eight possible dimensions appear in factor analysis. These dimensions are trust in: the patient-focus of health care providers; macro policies level will have no consequences for patients; expertise of health care providers; quality of care; information supply and communication by care providers and the quality of cooperation. The reliability of most scales is higher than 0.8. The validity of the dimensions is assessed by determining the correlation between the scales on the one hand, and people's experience and a general mark they would assign on the other. We conclude that public trust is a multi-dimensional concept, including not only issues that relate to the patient-doctor relationship, but also issues that relate to health care institutions. The instrument appears to be reliable and valid.

[State of the Dutch health care: need for more refined and specific indicators].

The 'World health report 2000' follows a trend towards the use of performance indicators in public services. The indicators used by WHO are in need of conceptual refinement and valid measurement, especially the more subjective ones. The use of indicators for final goals of health (care) systems makes it difficult to translate lack of performance into policy. Instrumental goals are also needed for the latter. It is concluded that the overall performance of the Dutch health care system is built up of the performance of its individual sections. The concrete areas for improvement within these sections need to be identified, while at the same time a performance paradox should be avoided.

Social democratic government and spatial distribution of health care facilities. The case of hospital beds in Germany.

BACKGROUND: In this paper, the hypothesis that the spatial distribution of hospital beds is more even in countries with socialist or social democratic governments than in countries with conservative or Christian democratic governments was tested. To avoid the confounding influences of historical and institutional differences between countries, we used the Federal Republic of Germany as a case study. The German federal states have their own governments who play an important role in creating structures for the planning of hospital facilities. METHODS: The test of the hypothesis was largely quantitative. At the level of federal states the rank correlation was computed between the weighted number of years of left-wing government participation and the coefficient of variation in the number of hospital beds per 1000 inhabitants. In addition to this, the hospital plans of two federal states were studied. RESULTS: The hypothesis was supported by the data, showing a positive association between the number of years of left-wing government participation and regional variation in the number of hospital beds. A comparison of the hospital plans of two contrasting federal states showed less government interference in hospital planning in the state with a tradition of right-wing government. CONCLUSION: There seems to be a relation between left-wing government participation in West German states and a more equal distribution of the number of hospital beds per 1,000 inhabitants.

Environmental and organizational determinants of quality management.

The aim of the study was to obtain more insight into the organizational and environmental determinants of the implementation of quality management in health care organizations. Primary survey data were collected in 1995 in a large nationwide study within 15 fields of health care and health care-related social services in The Netherlands. In general, there are more differences between health care organizations than between fields of health care. Environmental influence was found to be less important than was expected. Care-oriented organizations have a greater opportunity to involve their patients. It seems that apart from patients, the perceived pressure from other third parties has little influence on the implementation of quality management in health care organizations.

The effectiveness of quality systems in nursing homes: a review.

BACKGROUND: The need for quality improvement and increasing concern about the costs and appropriateness of health care has led to the implementation of quality systems in healthcare organisations. In addition, nursing homes have made significant investments in their development. The effects of the implementation of quality systems on health related outcomes are not yet clear. OBJECTIVE: To examine evidence in the literature on whether quality systems have an impact on the care process and the satisfaction and health outcomes of long term care residents. METHODS: Review of the literature. RESULTS: The 21 empirical studies identified concerned quality system activities such as the implementation of guidelines; providing feedback on outcomes; assessment of the needs of residents by means of care planning, internal audits and tuition; and an ombudsman for residents. Only four articles described controlled studies. The selected articles were grouped according to five focal areas of quality. The opinion of residents was seldom used to evaluate the effectiveness of quality systems. The effects on care processes and the health outcomes of long term care residents were inconsistent, but there was some evidence from the controlled studies that specific training and guidelines can influence the outcomes at the patient level. CONCLUSIONS: The design of most of the studies meant that it was not possible to attribute the results entirely to the newly implemented quality system. As it is difficult in practice to design a randomised controlled study, future research into the effectiveness of quality systems should not only focus on selected correlates of quality, but should also include a qualitative and quantitative (multivariate and multilevel) approach. The methods used to measure quality need to be improved.

All rights reserved, or can we just copy? Cost sharing arrangements and characteristics of health care systems.

In most European countries cost sharing has been introduced in order to reduce the demand for care. Different forms of cost sharing are available, but because of historically grown system characteristics and prevailing values countries differ in the application of specific forms. This review focuses on eighteen European countries, and on the combinations of health system characteristics and present forms of cost sharing. We found that some combinations are more present: different payment systems for primary care physicians go together with different forms of cost sharing, different services have different forms of cost sharing. In countries with a GP as gatekeeper no charges are in use for the GP. No distinct relationship could be found between the financing system (tax-based or insurance-based) and the form of cost sharing or the exclusion of vulnerable populations. It is concluded that there are two ways of filtering 'unnecessary' demand. One is by introducing cost sharing for directly accessible services such as GPs. The second way is by having GPs act as gatekeepers to more specialized, and more costly care.

Science in practice: can health care reform projects in central and eastern Europe be evaluated systematically?

Since the beginning of the 1990s, health care reform projects have taken place in many of the former Communist countries, but these projects are rarely evaluated systematically. Evaluation, however, is an important tool for increasing their rationality and continuity. The aim of this paper is to identify the difficulties in the efforts towards systematic evaluation and draw lessons for the future. For this aim, the requirements for a more rigorous, controlled evaluation are compared with our experiences of evaluating a health care reform project in the Slovak republic. From this comparison a number of discrepancies arise: it was difficult to set clear and realistic goals at the start of the project; the outcomes of the project could not always be measured, nor could 'the process' always be distinguished from the outcomes. Systematic evaluation was further hampered by an insufficient degree of structuration of the project, in advance and during the implementation, and by the absence of a tradition and infrastructure for data collection. On the basis of the experiences and relevant literature, recommendations for future evaluations are formulated. The main lesson is that, given the context, often it will not be possible to use an ambitious evaluation design, and concessions need to be made. At the same time, continuous efforts towards more systematic evaluation procedures should be made, but it is wise and more sustainable to do this in an incremental way.

[Effect of competition-oriented reform in the Netherlands health care system on the relationship between primary care physicians, insurance groups and insured patients].

The German health care policy debate is affected by proposals demanding the introduction of competitive elements. Analysis of the effects of regulated competition in the Netherlands health care system shows that actual behavioural changes of the key actors of the system differ considerably from expected changes, although incentives within the system have been substantially changed. Sickness funds are not selectively linked with providers and insured patients do not change their insurance company very often. From the point of view of the original reform targets, this preliminary result is quite disappointing. It can be explained by the fact that the relations between sickness funds, general practitioners and insured persons or patients are within a broader framework of health care. Thus, competition does not seem attractive to either of them. If regulated competition became more dominant, several undesirable effects on the so far well-appreciated primary care may be expected.

Regional disparities in health care supply in eleven European countries: does politics matter?

There are large differences both among and within European countries in the supply of health care facilities and personnel. In 1979 Smith posed the hypothesis that spatial disparities in health care supply will be smaller in countries with socialist (or social-democratic) governments. The aim of this paper is to examine this hypothesis by analysing whether or not regional disparities in health care supply within countries are smaller in countries that have been governed predominantly by socialist governments. We have collected regional data on the number of hospital beds and the number of physicians for 211 regions in 11 European countries for 1970 and 1990. Countries were classified according to the political composition of governments in the post-war era. It is concluded that: (1) the amount of regional variation is greater for hospital beds than for doctors; (2) for both aspects of supply, regional disparities decreased over time; (3) the decrease in regional disparities between 1970 and 1990, both for beds and for doctors in hospitals, was stronger for countries that had more years of socialist government in that period and (4) there is no relation between the number of years of socialist government between 1945 and 1990 and regional variation in health care supply in 1970, nor for government participation between 1970 and 1990 and variation in supply in 1990.

Neighbourhood characteristics and use of benzodiazepines in The Netherlands.

This paper analyses the relationship between individual and neighbourhood characteristics and the use of benzodiazepines within a Dutch city. It is hypothesized that the proportion of users is lower in more socially integrated and less deprived neighbourhoods. Hypotheses have been tested by using multi-level analysis to distinguish between composition and context effects. Age and gender have a clear relation to the use of benzodiazepines and neighbourhood differences in the proportion of users are partly the effect of population composition by age and gender. The proportion of users is higher in neighbourhoods with a higher percentage of one-parent families, with a lower percentage of social rented housing and with a larger number of rooms per person. The strength of the relation between age and use is influenced by neighbourhood characteristics. Neighbourhood variation in the amount used only depends on population composition.

Is there a geography of alternative medical treatment in The Netherlands?

An increasing number of people are using alternative medical care. The literature suggests that there are important between place variations, however. This paper tries to assess the extent of these variations and mechanisms behind them for the utilization of homeopathy, paranormal healing and manual therapy. Are these variations a matter of level of supply, degree of urbanization, GP characteristics or simply a matter of composition of populations? Data are derived from the Dutch National Surgery of General Practice and analyzed using multilevel logistic regression models. Between place variation in utilization of homeopathy is mainly a matter of composition of populations with respect to health locus of control and religion. With respect to paranormal healing, it is exclusively a matter of religion. With respect to manual therapy, place variations are a matter of individual, GP, as well as area characteristics, but a relatively large amount remains unexplained.

A measuring instrument for evaluation of quality systems.

OBJECTIVE: To develop an instrument for provider organizations, consumers, purchasers, and policy makers to measure and compare the development of quality systems in provider organizations. DESIGN: Cross-sectional study of provider organizations using a structured questionnaire to survey managers. SETTING: The Netherlands. STUDY PARTICIPANTS: Provider organizations of six health care fields: primary health care, care for the disabled, mental health care, care for the elderly, hospital care and welfare care. MAIN MEASURES: Existence of quality assurance and quality improvement activities. RESULTS: The study presents a survey instrument for assessing the quality assurance and improvement activities of health care provider organizations and the developmental stage of quality systems. The survey instrument distinguishes five focal areas for quality improvement activities and four developmental stages. The study also reports data on the reliability and validity of the survey instrument. CONCLUSION: The instrument is reliable, easy to administer, and useful across health care fields as well as different kinds of organizations. Developing quality systems provide a common language across all parts of the health care sector. By assigning the activities to focal areas and developmental stages the instrument gives insight into the implementation of quality systems in health care. Comparable information on quality assurance activities increases the accountability of providers. Because of the efficient (not time consuming) approach, the instrument complements existing accreditation reviews.

Medical practice variations: changing the theoretical approach.

Variations in medical practice are well documented, but there has been less progress in explaining these variations. This paper discusses the existing theories and hypotheses and concludes that a change in theoretical approach is required, to one that more directly highlights the social context influencing the behaviour of doctors in their daily practice. An initial alternative model for explaining variation in practice style is presented. The paper illustrates how (combinations of) important structural factors, such as the availability of hospital resources, the way the doctor is reimbursed, the availability of patients, professional uncertainty, and the way the hospital is financed, lead to hypotheses about when different local standards of medical care emerge. It is concluded that theoretical progress in research on variations in medical practice is possible and that empirical research needs to be driven by hypotheses that emphasize the role of social contexts in the doctor's decision behaviour. Some suggestions for future lines of research are outlined.
