Health care use by diabetic patients in the Netherlands: patterns and predicting factors.

AIMS: Diabetic patients require care from a variety of health care providers, but little is known about their actual use of health care. Aims of this study were to (1) obtain information on health care use by diabetic patients in the Netherlands, (2) distinguish patterns of health care utilisation among these patients, and (3) develop insight into the factors predicting these patterns. METHOD: Data on 388 diabetic patients were extracted from a nationally representative database of patients with chronic disease. Data on health care utilisation and background variables were collected in 1998 by means of a survey. Patients' GPs registered information about medical diagnosis, illness duration and co-morbidity. Analysis included descriptive statistics, as well as cluster and logistic analysis. RESULTS: Diabetic patients use a wide range of services, but large differences exist. Four patterns of health care utilisation could be distinguished: a pattern of low consumption, one of moderate consumption with a central role for internal medicine, one of more extensive diabetes care consumption, and one of high medical and home care consumption. Type 1 diabetes appeared to be an important determinant of the moderate, mainly internal medicine pattern and the more extensive diabetes care pattern. The pattern of high medical and home care was not predicted by diabetes type, but by the presence of co-morbidity and by poor self-rated health. CONCLUSION: Despite the fact that diabetic patients use a wide range of health care services, there seems to be a problem of under utilisation, especially among type 2 diabetic patients.

Psychometric properties of the RAND-36 among three chronic diseases (multiple sclerosis, rheumatic diseases and COPD) in The Netherlands.

OBJECTIVE: In this article, psychometric properties both of the total RAND-36 and of its subscales, such as unidimensionality, differential item functioning (DIF or item bias), homogeneity and reliabilities, are examined. METHODS: The data from populations with three chronic illnesses, multiple sclerosis (n = 448), rheumatism (n = 336) and COPD (n = 259), have been collected in different parts of the Netherlands. The main technique used was Mokken scale analysis for polytomous items. RESULTS: All subscales of the RAND-36 appeared to be unidimensional. For the subscales 'mental health' and general health perceptions' some minor indications of DIF for the different chronic illnesses were found. Reliabilities of almost all subscales in all subpopulations were higher than 0.80, while the homogeneities of almost all subscales in all subpopulations were higher than 0.50, indicating 'strong unidimensional, hierarchical scales'. CONCLUSIONS: In general, the subscales of the RAND-36 can be used to compare persons with different chronic illnesses. The subscale 'general health perceptions' did not function as well as would be preferred.

Stress in chronic disease: do the perceptions of patients and their general practitioners match?

OBJECTIVE: To compare the stressors accompanying chronic disease as perceived by patients and their GPs and to explore how incongruence in patients' and GPs' ideas influences patients' health status and use of health care. METHOD: A total of 580 patients with a diagnosis of diabetes or osteoarthritis and their GPs were interviewed by questionnaire about the stressors accompanying a patient's illness. In addition, information was obtained from each patient on health status and use of health care. RESULTS: The results show that patient and GP diverge in the way they think about chronic illness. Incongruence was larger in the case of osteoarthritis. In both diabetes and osteoarthritis, incongruence between patient and GP was associated with a worse health status of the patient and an increase in health-care use, although the pattern of correlation differed by type of disease. CONCLUSIONS: A chronic disease requires an ongoing relationship between patient and GP over years. Therefore, it is especially important that providers recognize the problems with which chronic disease patients are faced. Too often, providers are one-sided focused on the medical aspects of disease, neglecting the personal impact that a chronic disease has on the patient's life. In this way, successful treatment is complicated.

Which chronic conditions are associated with better or poorer quality of life?

The objective of the present study is to compare the QL of a wide range of chronic disease patients. Secondary analysis of eight existing data sets, including over 15,000 patients, was performed. The studies were conducted between 1993 and 1996 and included population-based samples, referred samples, consecutive samples, and/or consecutive samples. The SF-36 or SF-24 were employed as generic QL instruments. Patients who were older, female, had a low level of education, were not living with a partner, and had at least one comorbid condition, in general, reported the poorest level of QL. On the basis of rank ordering across the QL dimensions, three broad categories could be distinguished. Urogenital conditions, hearing impairments, psychiatric disorders, and dermatologic conditions were found to result in relatively favorable functioning. A group of disease clusters assuming an intermediate position encompassed cardiovascular conditions, cancer, endocrinologic conditions, visual impairments, and chronic respiratory diseases. Gastrointestinal conditions, cerebrovascular/neurologic conditions, renal diseases, and musculoskeletal conditions led to the most adverse sequelae. This categorization reflects the combined result of the diseases and comorbid conditions. If these results are replicated and validated in future studies, they can be considered in addition to information on the prevalence of the diseases, potential benefits of care, and current disease-specific expenditures. This combined information will help to better plan and allocate resources for research, training, and health care.

Hormone replacement therapy: changes in frequency and type of prescription by Dutch GPs during the last decade of the millennium.

OBJECTIVE: The present study was conducted in order to determine the change of frequency and type of hormone replacement therapy (HRT) regimen newly prescribed by Dutch GPs. METHODS: A comparison was made of two data sets (multi-stage random samples) collected in 1987/88 and from 1995 to 1998 concerning women 40 years and older who were newly prescribed HRT. RESULTS: Compared with 1987/88, 50% more patients were newly prescribed HRT in 1998 (2.0 in 1987/88 and 3.0 in 1998 per 1000 registered women, P < 0.01). The age distribution remained about the same, with a peak between 50 and 54 years in each year of registration. Unopposed oestrogens (including plasters) were prescribed less frequently (1.3 per thousand in 1987/88 versus 0.7 per thousand in 1998, P < 0.001), and combinations of oestrogen and progestogen more frequently in 1998 (0. 2 per thousand in 1987/88 versus 1.8 per thousand in 1998, P < 0. 01). Sequential therapy was prescribed slightly more frequently than continuous therapy (65% sequential therapy in 1995; 55% in 1998). The most frequent reason for starting HRT in 1995-1998 was climacteric symptoms (89-98%), followed by osteoporosis prevention (16-28%) and early menopause (13-25%). Rarely were preventive goals the only reason (6%) for prescribing HRT. CONCLUSIONS: The number of HRT prescriptions increased by 50% over the last decade of the millennium. The age distribution remained the same. There was a tendency to shift from prescribing unopposed oestrogens to combinations of oestrogens and progestogens. Alleviation of climacteric symptoms was the main reason for prescribing HRT throughout the registration period. Prescription of HRT for prevention of osteoporosis and/or cardiovascular disease has so far not been adopted on a large scale by Dutch GPs.

Trends in HIV-related consultation in Dutch general practice.

New medicine against AIDS and a possible changing attitude towards AIDS will affect the role of the general practitioner (GP). We aim to explore and assess the changing role of the GP in preventing and detecting AIDS, which will be done by providing insight into the changing numbers and content of HIV-related consultations in the general practice. Since 1988 a representative sample of 63 Dutch GPs have participated in a network. They recorded all face-to-face consultations with non HIV-infected patients in which the subject of AIDS was brought up. Timetrend analysis is used to investigate variations over time in the number and content of the consultations, GPs' actions and patients' characteristics. The influence of a rural or urban setting and the characteristics of the patients who are involved are also taken into account. Until 1994 a significant increase was found in the number of consultations. In highly urban areas the number of consultations is higher and still growing, whereas physicians in rural areas see fewer patients every year. The most important topic of conversation was the request for an HIV test (74%). This figure grew over the years, as did the number of tests performed. GPs became less passive and restrictive in advising tests. The group of patients has also changed, e.g. patients do not mostly belong to traditional risk groups anymore, and are significantly younger. AIDS seems to have become more familiar to patients and doctors. A lot of general information is available from different sources. Because of this change in attitude and knowledge of patients, the GPs' role as it relates to AIDS is becoming more specific in tracing infected patients and giving customized information to individuals. Patients visit their physicians less often because of concerns about AIDS, but the GP continues to fulfil a very important role in the prevention and detection of AIDS.

Patients with irritable bowel syndrome: health status and use of health care services.

BACKGROUND: The reason for consulting a physician is more related to illness behaviour than to the severity of complaints. Yet, little is known about the course of complaints, the health care seeking behaviour, and psychosocial factors influencing these items in patients with irritable bowel syndrome (IBS) attending the general practitioner (GP). AIM: To study health status, lifestyle, and use of health care services of patients with IBS in order to indicate problem areas accessible for intervention strategies. METHOD: Structured interviews of 53 patients with IBS aged 15 years and older compared with a general population of 12,975 in the same age range, all drawn from the Dutch National survey of Morbidity and Intervention in General Practice. RESULTS: Patients with IBS revealed a lower grade of education (P < 0.001), poorer health (P < 0.001), a higher mean complaint score (8.3 versus 4.0, P < 0.001), a higher score on the General Health Questionnaire (P < 0.001), a higher score on the biographic problem list (BIOPRO, 2.3 versus 1.4, P < 0.001), and more absence from work (32% versus 18% in two months, P < 0.01). Patients with IBS consulted the family physician (1.6 versus 0.8 in three months, P < 0.001), the physical therapist (30% versus 15% in one year, P < 0.001), and the alternative therapist (32% versus 15% in five years, P < 0.001) more often than those without. CONCLUSIONS: The study shows an excess of comorbidity, psychosocial problems, use of health care services, and absence owing to disease in patients with IBS. Special guidelines and training of GPs to apply a more integral approach may reduce the cost of health care and may lead to a more favourable course in patients with IBS.

[Migrants in family practice: their symptoms and diagnoses differ from the Dutch].

OBJECTIVE: To determine to what extent Turks, Moroccans and Surinamese differ from the Dutch in health problems, while taking the impact of relevant background characteristics into account. DESIGN: Secondary analysis. SETTING: Dutch Institute for health care research, Utrecht, the Netherlands. PATIENTS AND METHODS: In 1987/'88, 161 general practitioners and their assistants in 103 general practices recorded all patient contacts during three months in four consecutive periods for the Dutch National Survey on Morbidity and Interventions in General Practice. Data on 1165 Turkish, 853 Moroccan, 1355 Surinamese and 1471 Dutch persons (a 1% sample) between 18 and 65 years of age were used. Differences in health problems (complaints and diagnoses) between groups were tested by means of logistic regression analysis. Sex, age, educational level, working situation, marital status, health insurance, region and urbanisation were included in the analyses as covariates, for which the data were corrected. RESULTS: The pattern of complaints and diagnoses of ethnic minorities agreed with that of the Dutch in many respects, but there were also clear differences. Surinamese differed the most. Digestive problems, acute and chronic, eye problems, acute musculoskeletal problems, especially muscle pain or fibrositis, respiratory infections and eczema occurred more often in all three minority groups. Surinamese had more diagnoses in the categories of blood and endocrine/metabolic disorders (diabetes mellitus), Moroccanshad fewer diagnoses of the circulatory system (hypertension). Turks and Surinamese had more general and social problems, while Surinamese also had more psychological problems. CONCLUSION: In some areas ethnic minorities have more health problems than Dutch patients who are comparable with them in background characteristics. This clearly suggests an 'ethnic' factor.

[Management of psoriasis in family practice is now in closer agreement with the guidelines of the Netherlands Society of Family Physicians].

OBJECTIVE: To assess changes in incidence of psoriasis and to study changes in the management of psoriasis in general practice after the sending of guidelines on management of psoriasis to general practitioners (GPs) by the NHG. DESIGN: Secondary data analysis. SETTING: Netherlands Institute for Health Care Research (NIVEL), Utrecht, the Netherlands. METHOD: Data on the incidence of psoriasis and its management by general practitioners were collected from a file predating the publication of the NHG guideline 'Psoriasis' in 1994, namely the 'Dutch National Survey of General Practice' (NS; 1987/'88), and from a subsequent file, the 'Registration Network Groningen' (RNG; 1995). RESULTS: In the NS there were 106 new patients with psoriasis (incidence: 1.3/1000/year; 95% confidence interval (95% CI): 1.2-1.4) while in the RNG there were 24 (incidence: 1.2/1000/year; 95% CI: 0.7-1.9). In all, there were 466 psoriasis patients in the NS and 125 in the RNG. The number of referrals to dermatologists was halved in 1995 (7.2%) compared with 1987/'88 (14.4%; p < 0.05). The most frequently prescribed dermatologica in psoriasis was in 1995 corticosteroid group 3 (32.8%; in 1987/'88: 28.5%), but the rise was stronger in corticosteroid group 2 (29.6%; in 1987/'88: 16.0%; p < 0.001) and group 4 (16.0%; in 1987/'88: 8.8%; p < 0.05). CONCLUSION: The incidence of psoriasis in general practice had not changed between 1987/'88 en 1995. Referral pattern and prescription shifted towards the guidelines issued by the NHG.

Measuring morbidity of children in the community: a comparison of interview and diary data.

BACKGROUND: Little is known about the validity of estimates of morbidity experienced at home. METHODS: In the Dutch National Survey of Morbidity and Interventions in General Practice mothers of 1630 children answered a health interview and kept a health diary for 3 weeks (only the first 2 weeks were used). Children's symptoms were recorded during the interview using a check list and monitored in the health diary through open-ended questions. RESULTS: In the interview parents reported symptoms for 65% of their children and in the diary for 54% of children. Ear problems, colds, fever and weakness and anxiety were reported more often in the interview. Mother's mental health was assessed by the General Health Questionnaire; those scoring >4 were assessed as having impaired mental health and these parents reported symptoms for more children in the interview (81%) than in the diary (65%). For similar reference periods, the least educated mothers reported fewer children with symptoms in the diary (45%) than in the interview (66%). More highly educated mothers reported similarly in the diary (67%) and the interview (70%). CONCLUSION: Both data collection methods yield different estimates of community morbidity. Explanations such as telescoping, the seriousness of the symptoms, the amount of psychological distress of the respondent, forgetfulness and literacy limitations are discussed. We recommend that diaries should not be used in less educated populations.

Validity and accuracy of interview and diary data on children's medical utilisation in The Netherlands.

STUDY OBJECTIVE: To assess the validity and accuracy of children's medical utilisation estimates from a health interview and diary and the possible consequences for morbidity estimates. The influence of recall bias and respondent characteristics on the reporting levels was also investigated. DESIGN: Validity study, with the medical record of the general practitioner (GP) as gold standard. In a health interview and three week diary estimates of medical utilisation of children were asked and compared with a GP's medical record. SETTING: General community and primary care centre in the Netherlands. PARTICIPANTS: Parents of 1,805 children and 161 GPs. MAIN RESULTS: The sensitivity of the interview (0.84) is higher than the diary (0.72), while specificity and kappa are higher in the diary (0.96; 0.64) than in the interview (0.91; 0.5-8). Recall bias, expressed as telescoping and heaping, is present in the interview data. Prevalence estimates of all morbidity are much higher in the interview, except for skin problems. Compared with a parental diary more consultations are reported exclusively by the GP for children from ethnic minorities (OR 1.6), jobless (OR 2.3), and less educated mothers (OR 2.6). CONCLUSIONS: Estimates of medical utilisation rates of children are critically influenced by the method of data collection used. Interviews are prone to introduce recall bias, while diaries should only be used in populations with an adequate level of literacy. It is recommended that medical records are used, as they produce most consistent estimates.

Everyday symptoms in childhood: occurrence and general practitioner consultation rates.

BACKGROUND: Fewer than 20% of all illnesses that occur in the home require the attention of a general practitioner (GP). Whether specific illnesses in children are more likely to need the attention of a GP is poorly understood, as is the influence of various other factors. Health diaries are the most suitable method of collecting comprehensive information about children's health problems at home and in general practice simultaneously. AIM: To investigate the occurrence of, and consultation rates for, specific symptoms in childhood in relation to age, sex, birth order, and place of residence of the child, and season of the year. METHOD: The parents of 1805 children kept a health diary over three weeks and recorded symptoms and consultation behaviour. The symptoms were later combined into illness episodes. RESULTS: Over three weeks, colds/flu (157/1000 children) and respiratory symptoms (114/1000 children) occurred most frequently. More young children (0-4 years) suffered from illness generally. Eleven per cent of all illness episodes required the attention of a GP. Consultation rates differed greatly according to symptoms. A GP was consulted most often for ear (36%) and skin (28%) problems, and least often for headaches (2%) and tiredness (1%). Regardless of symptoms, young children (0-4 years) were taken to a GP twice as often as older children (10-14 years). CONCLUSIONS: This study emphasizes the enormous amount of illness that occurs in children and the fact that more than 80% of all illnesses are dealt with by parents without reference to the professional health care system.

Epilepsy patients: health status and medical consumption.

OBJECTIVE: To study the health status and medical consumption of outpatients with active epilepsy in comparison with the general population. DESIGN: Descriptive population study (multi-stage random sample). SETTING: Structured questionnaire. PATIENTS: Thirty-nine epilepsy patients compared with a general population of 12,975. RESULTS: Epilepsy patients revealed poorer health, a higher mean complaint score (5.3 versus 3.7, P < 0.05), a higher score on the General Health Questionnaire (P < 0.05), a somewhat higher score on the bio-logical problem list (BIOPRO) (1.8 versus 1.4, P > 0.05), less active sports engagement (16% versus 39%, P < 0.01), more fatigue (46 vs 29%, P < 0.05), dizziness (33 vs 10%, P < 0.01), nervousness (28 vs 18%, P > 0.05), sleep disturbance (23 vs 15%, P > 0.05) and excitability (33 vs 15%, P < 0.01) when compared with the general population. The BIOPRO showed problems in epilepsy patients on specific items related to self-confidence (P < 0.001) Epileptic patients do not show more absence due to illness, from work, school or at home (15 vs 18%, P > 0.05) and/or more problems at work or in the family when compared with the general population. Almost half of epilepsy patients had consulted a specialist in the past 2 months (46 vs 23% of the general population, P < 0.001). Epilepsy patients consulted the family physician slightly more often than other responders (3.0 versus 2.3, P > 0.05) and contacted the family physician's assistant considerably more often (2.3 versus 0.7, P < 0.001). One-third of epilepsy patients consulted an alternative healer in the past 5 years versus 14% in the general population (P < 0.001). CONCLUSIONS: The study shows an excess of psychosocial problems and medical consumption in epilepsy patients, but not more absence from work or problems at work or in the family. Further development of a quality of life instrument specific to epilepsy is advised.

[Little recognition of mental problems in children by parents and family physicians].

OBJECTIVE: To determine the prevalence of psychic problems in children in the Dutch GP-practice and to determine how often parents and general practitioners (GPs) recognize psychic problems in children. DESIGN: Descriptive. SETTING: World Health Organisation Collaborating Centre for Primary Health Care (NIVEL) and Academic Hospital, Department of Child and Adolescent Psychiatry, Utrecht, the Netherlands. METHOD: In 810 children presence or absence of emotional and behavioural problems was studied by means of the Child Behaviour Checklist (CBCL) filled out by a parent at the moment of contact with a GP. The GPs findings in these were also recorded. RESULTS: 7.7% of all children obtained a total CBCL score indicating presence of emotional and behavioural problems (> P90). These children had problems at school, had repeated a school year, and followed special education more often. Nevertheless most of their parents (86%) did not experience problems with their children and 40% of the parents did not report any psychic problem in the preceding 2 weeks. Only 15% of these children were completely free of signs and symptoms, however, as against 40% of children with low scores. The percentages of children with high scores consulting a GP, social work or mental health care agency were somewhat higher than the percentages of children without these problems, but only the last-mentioned difference was significant. Children saw the GP rarely because of psychosocial problems (n = 7; less than 1%; 1 had a high CBCL score). Regardless of the presence of emotional and behavioural problems, as assessed by the CBCL, the GP seldom diagnosed psychological or social problems in children (n = 11; 1.4%; 2 had a high CBCL score) and rarely suspected the complaints had a psychosocial background. CONCLUSION: Children with a high CBCL score did not visit their GPs more often. The perception by the parent appears to be crucial in the help-seeking process. In many children in whom the screening instrument indicated the presence of emotional and behavioural problems, parents did not consider their children as problematic and did not seek the help of a GP.

[Multiple sclerosis in family practice].

OBJECTIVE: To study the family physician's role in the diagnosis and treatment of multiple sclerosis (MS) patients. DESIGN: Descriptive. SETTING: Nederlands Instituut voor Onderzoek van de Gezondheidszorg, Utrecht, The Netherlands. METHOD: In the Dutch National survey of morbidity and intervention in general practice, data were collected by 161 general practices throughout the Netherlands (161 family physicians) regarding contacts with patients during three months. These data were examined for contacts which resulted in the diagnosis of MS and for comorbidity. RESULTS: MS patients (n = 118) had 4.3 encounters per 3 months with their family physician and (or) the practice assistant. In 5 patients MS was diagnosed for the first time. Apart from neurological complaints characteristic of MS the family physician was consulted most frequently for sleeping disorders, urinary tract infections and urine incontinence. One-third of patients depended on social security and 26% had a paid job. CONCLUSION: The family physician was consulted relatively frequently by MS patients. Apart from sleeping disorders remarkably few psychic complaints were noted.

Multiple sclerosis: management in Dutch general practice.

BACKGROUND AND OBJECTIVES: A descriptive study on 118 MS patients in general practice, to describe the family physician's role in diagnosis, treatment and follow-up of patients. METHOD: Random sample of 103 general practices (161 family physicians) throughout The Netherlands with a total list of 335,000 patients. RESULTS: MS patients had on average 5.7 encounters with general practice in 3 months compared to 2.3 in all other patients (P < 0.001). Home visits counted for 38.7% of all family physician's encounters in MS patients compared to 16.6% in all other patients (P < 0.01). The average encounter lasted 12.9 minutes per MS patient compared to 7.8 in all other patients (P < 0.01). Counselling by the family physician took place in all new patients and in 53% of known patients. Follow-up appointments were made with all new patients and 65.9% of all MS patients. Fifteen patients (12.7%) were newly referred to a specialist and 28 patients (24%) were still treated by specialists. No medication was prescribed to almost 40% of patients. Vitamin B, benzodiazepines, laxatives, antibiotics for treatment of urinary tract infections and muscle relaxants are the most frequently prescribed drugs. The average dose of vitamin B complex was 1.94 times the defined daily dose. CONCLUSIONS: The family physician spends more time than average on MS patients, carries out more home visits and takes care of treatment of symptoms and complications of MS. Counselling and follow-up of patients takes an important place in family physician's management of MS. Vitamin B complex is being prescribed (too) frequently in a (too) high dose.

Social support and stressful events in two dimensions: life events and illness as an event.

Previous research on the buffering effects of social support focused mainly on life events as stressors, and mental illness as outcome. Furthermore, the question as to why support influences illness has not been subjected to theoretical or empirical study much. In this article we develop a hypothesis on the basis of the theory of social capital. We hypothesize that specific types of social resources are more relevant to the consequences of some events than of others. We test this hypothesis in two ways: (1) by taking life events as stressor and occurrence of illness as outcome, and, which is somewhat unusual, (2) by taking illness as stressor and duration and disabilities of illness as the outcome. Analyses of a representative sample of the Dutch population (N = 10,110) reveal that receiving specific types of support does not lead to better health or less illness in cases of stress. On the contrary, people who are under stress and receive more support, also appear to report more illness, more disabilities and a longer duration. We suggest that in an open sample like ours, the disease level measured is not severe enough to assess buffer effects of social support.
