Ethnic differences in antenatal care use in a large multi-ethnic urban population in the Netherlands (Article)

2011-02-01T00:00:00Z

Objective: to determine differences in antenatal care use between the native population and different ethnic minority groups in the Netherlands. Design: the Generation R Study is a multi-ethnic population-based prospective cohort study. Setting: seven midwife practices participating in the Generation R Study conducted in the city of Rotterdam. Participants: in total 2093 pregnant women with a Dutch, Moroccan, Turkish, Cape Verdean, Antillean, Surinamese-Creole and Surinamese-Hindustani background were included in this study. Measurements: to assess adequate antenatal care use, we constructed an index, including two indicators; gestational age at first visit and total number of antenatal care visits.Logistic regression analysis was used to assess differences in adequate antenatal care use between different ethnic groups and a Dutch reference group, taking into account differences in maternal age, gravidity and parity. Findings: overall, the percentages of women making adequate use are higher in nulliparae than in multiparae, except in Dutch women where no differences are present.Except for the Surinamese-Hindustani, all women from ethnic minority groups make less adequate use as compared to the native Dutch women, especially because of late entry in antenatal care. When taking into account potential explanatory factors such as maternal age, gravidity and parity, differences remain significant, except for Cape-Verdian women. Dutch-Antillean, Moroccan and Surinamese-Creole women exhibit most inadequate use of antenatal care. Key conclusions: this study shows that there are ethnic differences in the frequency of adequate use of antenatal care, which cannot be attributed to differences in maternal age, gravidity and parity. Future research is necessary to investigate whether these differences can be explained by socio-economic and cultural factors. Implications for practise: clinicians should inform primiparous women, and especially those from ethnic minority groups, on the importance of timely antenatal care entry.

Process evaluation of an intensified preventive intervention to reduce cardiovascular risk in general practices in deprived neighbourhoods (Article)

2008-12-01T00:00:00Z

Background: A RCT, conducted to examine the effectiveness of a structured collaboration in general practice to provide intensified preventive care in patients at high cardiovascular risk yielded no effect in the total group but differences across healthcare centres and ethnic groups become apparent. We conducted a process evaluation to explain these differences. Methods: We assessed the reach of the target group and whether key intervention components (individual educational sessions, structured team meetings, and risk assessments) were performed as planned (maximum score for protocol completion is 11). Results: The reach was initially 91%, but only a minority of patients completed the intervention activities as planned. The average score of the number of intervention components was low (5.66 out of 11 (sd 2.8)) and varied between centres (4.84 to 7.40) and ethnic groups (4.89 to 7.38), with team meetings as the least implemented activity conform plan. Conclusion: This study indicates that adding a practice nurse and a peer health educator to the general practice did not seem to result in the desired collaboration between the healthcare personnel. Further research is needed to investigate the reasons behind the low participation rate of the patients in the intervention.

Intensified preventive care to reduce cardiovascular risk in healthcare centres located in deprived neighbourhoods: A randomized controlled trial (Article)

2008-08-01T00:00:00Z

Background: We examined the effectiveness of a structured collaboration in general practice between a practice nurse, a peer health educator, the general practitioner (GP) and a GP assistant in providing intensified preventive care for patients at high risk of developing cardiovascular diseases. DESIGN: A randomized controlled trial in three healthcare centres (18 GPs) in deprived neighbourhoods of two major Dutch cities. Methods: Two hundred seventy-five high-risk patients (30-70 years) from various ethnic groups were randomized to intervention (n=137) or usual care group (n=138). We determined group differences in outcomes [10-year absolute risk (Framingham risk equation), blood pressure, lipids and body mass index] at 12-month follow-up. Results: The 10-year absolute risk was reduced by 1.76% (standard error: 0.81) in intervention and by 2.27% (standard error: 0.69) in usual care group; the difference in mean change was 0.88% [95% confidence interval: -1.16 to 2.93]. In both groups significant reductions were observed in the following individual risk factors: total cholesterol, total cholesterol/high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol, with no relevance between group differences. Conclusion: The cardiovascular risk profile of intervention and control patients improved after 1-year follow-up. However, no extra effect of the structured preventive care on the risk for cardiovascular diseases was achieved.

Patients' evaluation of quality of care in general practice: What are the cultural and linguistic barriers? (Article)

2008-07-01T00:00:00Z

Objective: Increased migration implies increased contacts for physicians with patients from diverse cultural backgrounds who have different expectations about healthcare. How satisfied are immigrant patients, and how do they perceive the quality of care? This study investigated which patient characteristics (such as cultural views and language proficiency) are related to patients' satisfaction and perceived quality of care. Methods: Patients (n = 663) from 38 general practices in Rotterdam (The Netherlands) were interviewed. General satisfaction with the general practitioner (GP) was measured by a report mark. Perceived quality of care was measured using the 'Quote-mi' scale (quality of care through the patient's eyes-for migrants), which contains an ethnic-specific subscale and a communication process subscale. Using multilevel regression techniques, the relation between patient characteristics (ethnicity, age, education, Dutch language proficiency, cultural views) and satisfaction and perceived quality of care was analysed. Results: In general, patients seemed fairly satisfied. Non-Western patients perceived less quality of care and were less satisfied than Dutch-born patients. The older the patients and the more modern cultural views they had, the more satisfied they were about the GP in general, as well as about the communication process. However, non-Western patients holding more modern views were the most critical regarding the ethnic-specific quality items. The poorer patients' Dutch language proficiency, the more negative they were about the communication process. Conclusion: It is concluded that next to communication aspects, especially when the patient's proficiency in Dutch is poor, physician awareness about the patient's cultural views is very important during the consultation. This holds especially true when the immigrant patient seems to be more or less acculturated. Practice implications: Medical students and physicians should be trained to become aware of the relevance of patients' different cultural backgrounds. It is also recommended to offer facilities to bridge the language barrier, by making use of interpreters or cultural mediators.

Different distribution of cardiovascular risk factors according to ethnicity: A study in a high risk population (Article)

2008-05-16T00:00:00Z

This study compares the distribution of cardiovascular risk factors in different ethnic groups at high risk of developing cardiovascular diseases within general practices. A total of 430 patients (179 Dutch, 126 Turks, 50 Surinamese, 23 Moroccans, 23 Antilleans and 29 from other ethnic groups) were included in the study. Data collection consisted of questionnaires and physical and clinical examinations. 54% was female. The mean age was 53.1 (sd 9.9) years. There were important ethnic differences in the distribution of cardiovascular risk factors. Compared to the Dutch, ethnic minorities had significantly greater odds of being diabetic (OR = 3.2-19.4); but were less likely to smoke (OR = 0.10-0.53). Turkish individuals had a lower prevalence of hypercholesterolemia but were 2.4 times more likely to be obese than the Dutch. Hypertension was very common in all ethnic groups and no significant ethnic differences were found. These findings provide additional evidence of the need for tailored interventions for different ethnic groups in general practices.

No evidence for marked ethnic differences in accuracy of self-reported diabetes, hypertension, and hypercholesterolemia (Article)

2007-12-01T00:00:00Z

Objective: To assess whether the accuracy of self-reported diabetes, hypertension, and hypercholesterolemia in high-risk groups differs according to ethnicity. Study Design and Setting: We analyzed data of 430 patients at high risk of cardiovascular disease from different ethnic origin, including Turkish, Surinamese, and Dutch. Risk factors based on self-reports were compared with data from medical records and with a gold standard based on clinical measurements. Proportions of concordance between self-reports and other methods and kappa statistics (κ) were determined by ethnicity. Results: Concordance between self-reports and other data sources was highest in diabetes and lowest for hypercholesterolemia. Agreement of self-reports was substantial to almost perfect for diabetes (κ: 0.84-0.76), substantial to moderate for hypertension (κ: 0.63-0.51), and moderate for hypercholesterolemia (κ: 0.55-0.48). There was no statistically significant association between ethnicity and concordance, except for self-reporting of diabetes among Surinamese vs. Dutch indigenous patients (odds ratio = 0.37; 95% confidence interval: 0.14-0.97). Conclusion: There are no marked ethnic differences in the accuracy of self-reports of diabetes, hypertension, and hypercholesterolemia in high-risk populations. Larger studies including multiple ethnic groups are needed to confirm these findings.

Tailoring intervention procedures to routine primary health care practice; an ethnographic process evaluation (Article)

2007-09-06T00:00:00Z

Background. Tailor-made approaches enable the uptake of interventions as they are seen as a way to overcome the incompatibility of general interventions with local knowledge about the organisation of routine medical practice and the relationship between the patients and the professionals in practice. Our case is the Quattro project which is a prevention programme for cardiovascular diseases in high-risk patients in primary health care centres in deprived neighbourhoods. This programme was implemented as a pragmatic trial and foresaw the importance of local knowledge in primary health care and internal, or locally made, guidelines. The aim of this paper is to show how this prevention programme, which could be tailored to routine care, was implemented in primary care. Methods. An ethnographic design was used for this study. We observed and interviewed the researchers and the practice nurses. All the research documents, observations and transcribed interviews were analysed thematically. Results. Our ethnographic process evaluation showed that the opportunity of tailoring intervention procedures to routine care in a pragmatic trial setting did not result in a well-organised and well-implemented prevention programme. In fact, the lack of standard protocols hindered the implementation of the intervention. Although it was not the purpose of this trial, a guideline was developed. Despite the fact that the developed guideline functioned as a tool, it did not result in the intervention being organised accordingly. However, the guideline did make tailoring the intervention possible. It provided the professionals with the key or the instructions needed to achieve organisational change and transform the existing interprofessional relations. Conclusion. As tailor-made approaches are developed to enable the uptake of interventions in routine practice, they are facilitated by the brokering of tools such as guidelines. In our study, guidelines facilitated organisational change and enabled the transformation of existing interprofessional relations, and thus made tailoring possible. The attractive flexibility of pragmatic trial design in taking account of local practice variations may often be overestimated.

Coping with methodological dilemmas; about establishing the effectiveness of interventions in routine medical practice (Article)

2006-01-01T00:00:00Z

Background: The aim of this paper is to show how researchers balance between scientific rigour and localisation in conducting pragmatic trial research. Our case is the Quattro Study, a pragmatic trial on the effectiveness of multidisciplinary patient care teams used in primary health care centres in deprived neighbourhoods of two major cities in the Netherlands for intensified secondary prevention of cardiovascular diseases. Methods: For this study an ethnographic design was used. We observed and interviewed the researchers and the practice nurses. All gathered research documents, transcribed observations and interviews were analysed thematically. Results: Conducting a pragmatic trial is a continuous balancing act between meeting methodological demands and implementing a complex intervention in routine primary health care. As an effect, the research design had to be adjusted pragmatically several times and the intervention that was meant to be tailor-made became a rather stringent procedure. Conclusion: A pragmatic trial research is a dynamic process that, in order to be able to assess the validity and reliability of any effects of interventions must also have a continuous process of methodological and practical reflection. Ethnographic analysis, as we show, is therefore of complementary value.

Blood pressure patterns in rural, semi-urban and urban children in the Ashanti region of Ghana, West Africa. (Article)

2005-11-01T00:00:00Z

BACKGROUND: High blood pressure, once rare, is rapidly becoming a major public health burden in sub-Saharan/Africa. It is unclear whether this is reflected in children. The main purpose of this study was to assess blood pressure patterns among rural, semi-urban, and urban children and to determine the association of blood pressure with locality and body mass index (BMI) in this sub-Saharan Africa setting. METHODS: We conducted a cross-sectional survey among school children aged 8-16 years in the Ashanti region of Ghana (West-Africa). There were 1277 children in the study (616 boys and 661 females). Of these 214 were from rural, 296 from semi-urban and 767 from urban settings. RESULTS: Blood pressure increased with increasing age in rural, semi-urban and urban areas, and in both boys and girls. The rural boys had a lower systolic and diastolic blood pressure than semi-urban boys (104.7/62.3 vs. 109.2/66.5; p < 0.001) and lower systolic blood pressure than urban boys (104.7 vs. 107.6; p < 0.01). Girls had a higher blood pressure than boys (109.1/66.7 vs. 107.5/63.8; p < 0.01). With the exception of a lower diastolic blood pressure amongst rural girls, no differences were found between rural girls (107.4/64.4) and semi-urban girls (108.0/66.1) and urban girls (109.8/67.5). In multiple linear regression analysis, locality and BMI were independently associated with blood pressure in both boys and girls. CONCLUSION: These findings underscore the urgent need for public health measures to prevent increasing blood pressure and its sequelae from becoming another public health burden. More work on blood pressure in children in sub-Saharan African and other developing countries is needed to prevent high blood pressure from becoming a major burden in many of these countries.

The effect of educational intervention on intercultural communication: results of a randomised controlled trial (Article)

2005-01-01T00:00:00Z

BACKGROUND: Due to worldwide migration to Western countries, physicians are increasingly encountering patients with different ethnic backgrounds. Communication problems can arise as a result of differences in cultural backgrounds and poor language proficiency. AIMS: To assess the effectiveness of an educational intervention on intercultural communication aimed to decrease inequalities in care provided between Western and non-Western patients. DESIGN OF STUDY: A randomised controlled trial with randomisation at the GP level and outcome measurements at the patient level. SETTING: General practice in Rotterdam. METHOD: Thirty-eight Dutch GPs in the Rotterdam region, with at least 25% of inhabitants of non-Western origin, and 2407 visiting patients were invited to participate in the study. A total of 986 consultations were finally included. The GPs were educated about cultural differences and trained in intercultural communication. Patients received a videotaped instruction focusing on how to communicate with their GP in a direct way. The primary outcome measure was mutual understanding and the secondary outcomes were patient's satisfaction and perceived quality of care. The intervention effect was assessed for all patients together, for the 'Western' and 'non-Western' patients, and for patients with different cultural backgrounds separately. RESULTS: An intervention effect was seen 6 months after the intervention, as improvement in mutual understanding (and some improvement in perceived quality of care) in consultations with 'non-Western' patients. CONCLUSIONS: A double intervention on intercultural communication given to both physician and patient decreases the gap in quality of care between 'Western' and 'non-Western' patients.

Ethnic specific recommendations in clinical practice guidelines: a first exploratory comparison between guidelines from the USA, Canada, the UK, and the Netherlands (Article)

2003-01-01T00:00:00Z

OBJECTIVES: To investigate whether clinical practice guidelines in different countries take ethnic differences between patients into consideration and to assess the scientific foundation of such ethnic specific recommendations. DESIGN: Analysis of the primary care sections of clinical practice guidelines. SETTING: Primary care practice guidelines for type 2 diabetes mellitus, hypertension, and asthma developed in the USA, Canada, the UK, and the Netherlands. MAIN OUTCOME MEASURES: Enumeration of the ethnic specific information and recommendations in the guidelines, and the scientific basis and strength of this evidence. RESULTS: Different guidelines do address ethnic differences between patients, but to a varying extent. The USA guidelines contained the most ethnic specific statements and the Dutch guidelines the least. Most ethnic specific statements were backed by scientific evidence, usually arising from descriptive studies or narrative reviews. CONCLUSION: The attention given to ethnic differences between patients in clinical guidelines varies between countries. Guideline developers should be aware of the potential problems of ignoring differences in ethnicity.

Measuring morbidity of children in the community: a comparison of interview and diary data (Article)

1998-01-01T00:00:00Z

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 (Article)

1998-01-01T00:00:00Z

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 (Article)

1998-01-01T00:00:00Z

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.

Illness in Children and Parental Response (Doctoral Thesis)

1997-06-18T00:00:00Z

Most children suffer from illnesses from time to time. In only a small part of these ill children parents decide to seek professional help. So, most child health care is carried out by parents. In general, this phenomenon is called the iceberg of symptoms. The part of the iceberg under the surface is the illness that is experienced but not brought to the attention of a health care provider. Often this illness is of a self-limiting nature and medical attention is not necessary. The part above the surface consists of the illnesses brought to the attention of a health care professional, which In The Netherlands is the general practitioner (GP) for adults as well as for children.

Children referred for specialist care: a nationwide study in Dutch general practice (Article)

1997-01-01T00:00:00Z

BACKGROUND: Insight into referral patterns provides general practitioners (GPs) and specialists with a frame of reference for their own work and enables assessment of the need for secondary care. Only approximate information is available. AIM: To determine how often, to which specialties and for what conditions children in different age groups are referred, as well as how often a condition is referred given the incidence in general practice. METHOD: From data of the Dutch National Survey of Morbidity and Interventions in General Practice, 63,753 new referrals (acute and non-acute) were analysed for children (0-14 years) from 103 participating practices (161 GPs) who registered. Practices were divided into four groups. Each group of practices participated for three consecutive months covering a whole year altogether. We calculated referral rates per 1000 children per year and referability rates per 100 episodes, which quantifies the a priori chance of a condition being referred for specialist care. RESULTS: The referral rate varied by age from 231 for children under 1 year old to 119 for those aged 10-14 years (mean 159). The specialties mainly involved were ENT, paediatrics, surgery, ophthalmology, dermatology and orthopaedics. Referrals in the first year of life were most frequently to paediatricians (123); among older children the referral rate to paediatricians decreased (mean 36). Referrals to ENT specialists were seen particularly in the age groups 1-4 (71) and 5-9 (53). For surgery, the referral rate increased by age from 19 to 34. Differences between boys and girls were small, except for surgery. The highest referral rates were for problems in the International Classification of Primary Care (ICPC) chapters: respiratory (28); musculoskeletal (25); ear (24) and eye (21). Referability rates were, in general, low for conditions referred to paediatrics and dermatology and high for surgery and ophthalmology. The variation in problems presented to each specialty is indicated by the proportion of all referrals constituted by the 10 most frequently referred diagnoses: from 35% for paediatrics to 81% for ENT; for ophthalmology, five diagnoses accounted for 83% of all referrals. CONCLUSIONS: The need for specialist care in childhood is clarified with detailed information for different age categories, specialties involved and variation in morbidity presented to specialists, as well as the proneness of conditions to be referred.

Molluscum contagiosum in Dutch general practice (Article)

1994-01-01T00:00:00Z

BACKGROUND: While molluscum contagiosum is considered to be a frequently encountered disease, few data on its incidence are known. AIM: The objective of this study was to describe the incidence of molluscum contagiosum in Dutch general practice and to assess the importance of venereal molluscum contagiosum. METHOD: Data were taken from the national survey of morbidity and interventions in general practice, drawn from 103 practices across the Netherlands, with a study population of 332300. RESULTS: The infection appeared to be common in childhood (cumulative incidence 17% in those aged under 15 years); the adult, sexually transmitted, form was rare. Incidence was higher between January and June than between July and December. Cases were unequally divided between recording practices, which is though to have been caused by the occurrence of small epidemics. CONCLUSION: The incidence of molluscum contagiosum in Dutch general practice was found to be 2.4 per 1000 person years. Molluscum contagiosum should still be considered as a mainly paediatric disease.
