Introduction: In general practice many patients present with emotional symptoms. Both patients and physicians desire effective non-pharmacological treatments.
Aim: To study the effectiveness of problem-solving treatment (PST) delivered by trained general practice registrars (GP registrars) for patients with emotional symptoms.
Purpose: In screening for type 2 diabetes, guidelines recommend targeting high-risk individuals. Our objectives were to assess the yield of opportunistic targeted screening for type 2 diabetes in primary care and to assess the diagnostic value of various risk factors.
Methods: In 11 family practices (total practice population = 49,229) in The Netherlands, we conducted a stepwise opportunistic screening program among patients aged 45 to 75 years by (1) identifying high-risk individuals (=1 diabetes risk factor) and low-risk individuals using the electronic medical record, (2) obtaining a capillary fasting plasma glucose measurement, repeated on a separate day if the value was greater than 110 mg/dL, and (3) obtaining a venous sample if both capillary fasting plasma glucose values were greater than 110 mg/dL and at least 1 sample was 126 mg/dL or greater.
Purpose: Because recognition and management of patients with somatoform disorders are difficult, we wanted to determine the specificity, sensitivity, and the test-retest reliability of the 15-symptom Patient Health Questionnaire (PHQ-15) for detection of somatoform disorders in a high-risk primary care population.
Methods: We studied the performance of the PHQ-15 in comparison with the Structured Clinical Interview for the Diagnostic and Statistical Manual-IV Axis I disorders (SCID-I) as a reference standard. From January through September 2006, we approached patients for participation.
Background: Currently only about half of the people who have major depressive disorder are detected during regular health care. Screening in high-risk groups might be a possible solution.
Aims: To evaluate the effectiveness of selective screening for major depressive disorder in three high-risk groups in primary care: people with mental health problems, people with unexplained somatic complaints and people who frequently attend their general practitioner.
Background: Fourty years of morbidity registration in general practice is a milestone urging to present an overview of outcomes. This paper provides insight into the infrastructure and methods of the oldest practice-based research network in the Netherlands and offers an overview of morbidity in a general practice population. Changes in morbidity and some striking trends in morbidity are presented.

Methods: From 2000 to 2001, in 11 Dutch general practices (n=49,229) we invited at-risk patients during usual care for a capillary fasting plasma glucose (cFPG1) measurement. If >6.
Purpose: Ongoing care for patients with skin diseases can be optimized by understanding the incidence and population prevalence of various skin diseases and the patient-related factors related to the use of primary, specialty, and alternative health care for these conditions. We examined the recent prevalence of skin diseases in a defined population of family medicine patients, self-reported disease-related quality of life, extent and duration of skin disease, and the use of health care by patients with skin diseases.
Methods: We undertook a morbidity registry-based epidemiological study to determine the prevalence of various skin diseases, using a patient questionnaire to inquire about health care use, within a network of family practices in the Netherlands with a practice population of approximately 12,000 citizens.
Objective: The efficacy of programmes to reduce long-term benzodiazepine use could be compromised by subsequent increases in contacts with the family practice. In this study the hypothesis was tested as to whether participation in a benzodiazepine discontinuation programme affects the frequency of contacts with the family practice.
Design: A controlled stepped-care intervention programme to decrease long-term benzodiazepine use.
Background: Early exposure of general practitioners to research is recommended to increase family medicine research capacity. However, vocational training programs encounter difficulties in engaging general practice registrars in research projects. The authors investigated registrars' opinions of research and their participation in research in daily practice.

However, when the periods are sufficiently spaced in time, sociodemographic changes may have occurred. The aim of this study is to examine in which respects the sociodemographic composition of lowest SES group changed between 1987 and 2001.

Objective: To assess the value of the GP's EMR in identifying patients at risk for undiagnosed type 2 diabetes and the feasibility to use this information in usual care to initiate screening.
Objective: To examine whether dieting--restriction of food intake for the purpose of weight control--suppresses or promotes excessive food intake and weight gain.
Design: A 4-year follow-up study of a dietary intervention in a sample of 97 patients with newly diagnosed Type 2 diabetes.
Main Outcome Measures: Weight gain, change in body mass index (measured weight in kilograms divided by measured height squared), and intake of energy, as measured with a food frequency questionnaire, were assessed in relation to dietary restraint and tendency to overeat (emotionally or externally induced overeating), as assessed with the Dutch Eating Behaviour Questionnaire.
Aim: To study the effects of a team-based model for continuous quality improvement (CQI) on primary care practice management.
Design Of Study: Randomised controlled trial.
Setting: Twenty-six intervention and 23 control primary care practices in the Netherlands.
Background: This study aims to examine the impact of women's characteristics (demographics, risk behaviour, and beliefs) on the uptake of cervical cancer screening, taking practice characteristics (demographic and organizational) into account.
Methods: Routinely collected data of screening status were sampled from electronic medical records of 32 Dutch general practices. Additionally, a questionnaire was sent to a sample of 2224 listed women-1204 screened, 1020 unscreened.
Background: The growing complexity of care with more professionals involved is a threat to the delivery of coherent and consistent care. Excellent exchange of information between professionals may be a way to maintain continuity of care. Relevant information to be passed over includes thoughts about future management for individual patients.

Objective: This study analyzed the long-term outcome of cardiovascular risk in a family practice population.
Introduction: The aim of this study was to investigate whether teenagers and adolescents (10-22 years) with asthma or asymptomatic bronchial hyperresponsiveness, were more likely to experience vocational or professional career limitations in the future, as compared to non-asthmatic contemporaries.
Methods: Data were used from a 14-year follow-up study in general practice, investigating the relationship between respiratory health in childhood and adolescence. At follow-up, the respiratory health status and information about career limitations were obtained.
Background: As morbidity registrations generally do not make distinct first and following myocardial infarctions, it is still unclear as to what extent the falling rates of myocardial infarctions are caused by lower incidences of first myocardial infarctions.
Aim: To investigate the incidence of first myocardial infarctions in a general practice population.
Method: Data were taken from the Continuous Morbidity Registration (CMR) Nijmegen, which has been collecting data from four general practices since 1971.
The aim of this exploratory study was to investigate associations between sick leave in workers with asthma or COPD and disease-related variables, psychosocial variables, and work characteristics. Hundred and eighty-nine patients with physician-diagnosed asthma (N=118) or COPD (n=71) who had paid work in the past 12 months completed questionnaires on sick leave, health complaints, functional limitations, work characteristics and psychosocial issues, and underwent a pulmonary function test (FEV1 and FVC before and after bronchodilation). Logistic regression analyses were performed to investigate variables independently associated with high sick leave (i.

The aim was to study whether combining frequency and age of onset of wheezing illness with respiratory and atopic morbidity at age 0-6 years and sociodemographic parameters for asthma might be helpful for the general practitioner to diagnose asthma early and accurately.
Methods: Birth cohort, mean follow-up 20 years (SD 4.
Objective: To assess the effects of stage-matched nutrition counseling on stages of change and fat intake.
Design: Controlled clinical trial.
Setting: 9 family practices in a family medicine practice network.
Background: The practice setting is, next to the GP and staff, an important determinant of the quality of care. Differences between single-handed practices and group practices in practice management and organization could therefore provide clues for improvement. An explorative, cross sectional survey was conducted in 766 general practices in The Netherlands comparing single-handed practices with group practices.
