[Sexual contact between general practitioner and patient in the Netherlands: prevalence and risk factors].

OBJECTIVE: To obtain data on sexual contact between general practitioners (GPs) and their patients and to determine the relationship between sexual abuse and GP characteristics. DESIGN: Cross-sectional. METHOD: In February-May 2002, anonymous questionnaires were mailed to a randomized sample of 1250 general practitioners in the Netherlands. RESULTS: A total of 977 general practitioners responded (response: 80%). This number included relatively large numbers of women and GPs aged > or = 50. Out of the 977 GPs, 32 had had sexual contact with a patient at some time: 30/695 (4.3%) of the male GPs and 2/247 (0.8%) of the female GPs Coitus was reported by 24 (75%) of them. Of the 32 perpetrators 11 (34%) had had sexual contact with 2 or more patients. Of the 30 male GPs who engaged in sexual contact with patients, 20 (67%) afterwards felt positive about the sexual encounter for himself and 22 (73%) for the patient. Sexual contact with a patient occurred more often among men who at the time of the survey were aged < or = 50 [corrected]. The incidence was not related to the degree of urbanisation of the practice area or to the size of the practice partnership. CONCLUSION: Sexual contacts between general practitioners and their patients are not just incidents. It is not enough to be conscious of one's own sexual feelings towards patients. Implementation of a clear policy is needed.

[Less ethnic knowledge in the Dutch College of General Practitioner's practice guidelines on type 2 diabetes mellitus, hypertension and asthma in adults than in the supporting literature].

OBJECTIVE: To assess whether ethnic differences present in the scientific literature used as the basis for the Dutch College of General Practitioner's (NHG) practice guidelines were reflected in the ethnic-specific information the guidelines contained. DESIGN: Analysis of published information. METHOD: The scientific literature used as the basis for the guidelines about type 2 diabetes mellitus, hypertension and asthma in adults was collected and carefully screened. Relevant ethnic-specific information was compared to the content of the guidelines. RESULTS: Several relevant ethnic differences were stated in the scientific literature used as the basis for the guidelines. Differences in prevalence and clinical progress were stated for type 2 diabetes mellitus, differences in lung-volume were stated for asthma and differences in prevalence, onset, complications, response to pharmacological treatment and dietary salt restriction were stated for hypertension. The type 2 diabetes mellitus guideline stated a higher prevalence of diabetes in Hindustani people and recommended earlier screening in this group. The asthma guideline stated that the lung volume is dependent of ethnicity. The hypertension guideline did not state any ethnic-specific information. CONCLUSION: The guidelines on type 2 diabetes mellitus, hypertension and asthma in adults only adopted a limited number of the ethnic differences contained in the scientific literature on which they were based. Possible explanations are that information was only included if there was a clear scientific basis, and that ethnic distinctions were found to be politically and socially undesirable. However, this lack of information might lead to ineffective or sub-optimal care for ethnic minorities.

Cardiovascular risk detection and intervention in general practice: the patients' views.

OBJECTIVE: To assess patients' views on the organization of (cardiovascular) preventive care. DESIGN: Prospective questionnaire survey with measurements shortly after risk assessment (T1) and after 1 year of risk intervention (T2). SETTING: Twenty-seven general practices participating in a project to enhance systematic cardiovascular disease prevention in two regions in The Netherlands. STUDY PARTICIPANTS: Two-hundred and ninety-eight successive patients aged 30-60 years identified with an elevated cardiovascular risk. MAIN OUTCOME MEASURES: Organizational aspects such as the acceptability of the care provider, practicality of special clinics, accessibility of the practice for routine care. RESULTS: Most of the respondents (74%) had no preference for a care provider in cardiovascular preventive care and only a few patients (3%) reported having little confidence in the expertise of the practice assistant to provide such care. The vast majority (88%) considered special preventive clinics to be practical, especially at T1. Most of the respondents (76%) did not report a decline in the accessibility of their practice for routine care. These outcome measures were not affected by age, sex, educational level or the number of risk factors measured during 1 year of risk intervention. CONCLUSION: Most patients did not have any major objections against the organization of preventive care through opportunistic case finding and risk monitoring in special preventive clinics managed by the practice assistant.

Tailored outreach visits as a method for implementing guidelines and improving preventive care.

OBJECTIVES: Authors of successful outreach visit studies stress the importance of tailoring the intervention to the unique attributes and needs of each practice. For a better understanding of the outreach visit method, the tailoring mechanism is explored in this article. The variation among practices in preventive outreach visits to implement guidelines and characteristics that determine the variation (baseline adherence to organizational guidelines, practice and visitor characteristics) are described. We explored whether and how many visits were paid to practices that showed no increase in adherence to guidelines. SETTING AND STUDY PARTICIPANTS: For 18 months, six trained nurse visitors assisted 33 family practices in implementing a set of guidelines to organize a program for cardiovascular disease prevention. MEASURES: Visit and consultative action parameters (number and duration of visits, duration of training and of conferring) and increase in adherence to organizational guidelines after 18 months of assistance compared to baseline adherence. RESULTS: Practices differed considerably concerning the visit and consultative action parameters. Exploratory multiple regression analysis showed that baseline adherence to guidelines, and practice and visitor characteristics were related to the number of visits. Visitor characteristics were strongly related to the total time spent on visits, training, and conferring. DISCUSSION: Our findings confirm that, concerning the number of visits, assistance is primarily adapted to the unique attributes of each clinic. It may be useful, from the viewpoint of cost-effectiveness, to standardize the performance of visitors somewhat more with regard to the visit length. The tailoring mechanism resulted in time well spent in assisting practices. We hope that our results contribute to the further development of the outreach method.

Relationship between practice organization and cardiovascular risk factor recording in general practice.

BACKGROUND: Research findings suggest that the level of cardiovascular risk factor recording in general practice is not yet optimal. Several studies indicate a relation between the organization of cardiovascular disease prevention at practice level and cardiovascular risk factor recording. AIM: To explore the relation between the organization of cardiovascular disease prevention and risk factor recording in general practice. METHOD: A cross-sectional study was conducted using data on adherence to selected practice guidelines and on cardiovascular risk factor recording from 95 general practices. Practice guidelines were developed beforehand in a consensus procedure. Adherence was assessed by means of a questionnaire and practice observations. Risk factor recording was assessed by an audit of 50 medical records per practice. RESULTS: Factor analysis of risk factor recording revealed three dimensions explaining 76% of the variance: recording of health-related behaviour, recording of clinical parameters, and recording of medical background parameters. Adherence to the guideline 'proactively invite patients to attend for assessment of cardiovascular risk' was related to a higher recording level in all three dimensions. Practice characteristics did not show a consistent relationship to the level of risk factor recording. CONCLUSION: This study indicates that the presence of a system of proactive invitation was related to the recording of cardiovascular risk factors in medical records in general practice.

[Left ventricular hypertrophy; differences in the diagnostic and prognostic value of electrocardiography and echocardiography].

OBJECTIVE: To compare the electrocardiogram (ECG) and the echocardiogram for demonstration of left ventricular hypertrophy (LVH) and the prognostic values of these methods. DESIGN: Literature study. SETTING: Department of General Practice, Social and Nursing Home Medicine, R.C. University of Nijmegen, the Netherlands. METHOD: Using articles retrieved by means of a search action in Medline (1962-January 1996), a study was made of the differences between determination of LVH by ECG and by echocardiography with regard to the sensitivities and specificities for measuring anatomical LVH, and their predictive values concerning cardiovascular morbidity and mortality. RESULTS: The sensitivity of echocardiography for the prediction of anatomical LVH (88-93%) exceeded that of ECG (21-54%), while both methods had a high specificity (77-97%). ECG-LVH seemed a better predictor of cardiovascular complications than echo-LVH. CONCLUSION: Echocardiography is the better instrument for screening for LVH, but ECG should keep its place in the diagnostics of LVH in view of its high predictive value for morbidity and mortality and its availability to primary health care. In regard to LVH, echocardiography measures only morphological disorders, while ECG also detects functional disorders.

Persisting improvement in complaint-related cognitions initiated during medical consultations in functional abdominal complaints.

BACKGROUND: Previously it was shown that during a series of out-patient consultations dysfunctional complaint-related cognitions and anxiety diminished significantly in patients with functional abdominal complaints (IBS). The aim of the present study was to assess the maintenance of positive changes initiated during medical consultations in the patients' complaint-related cognitions and anxiety, as well as the influence of these cognitions on the severity of the complaints, 6 months after the first visit to the out-patient clinic. METHODS: One hundred and five consecutive patients with IBS referred by their general practitioners to the out-patient clinic for internal medicine completed questionnaires about their complaints and their complaint-related cognitions and anxiety before the first and after the last out-patient visit and again at follow-up, 6 months after the first out-patient consultation. RESULTS: Positive changes in the patients' complaint-related cognitions during the consulting period were found to persist during the follow-up period. Improvement in abdominal complaints at follow-up was found to be related to the level of the patients' state anxiety, fear of cancer, and catastrophizing cognitions at the last out-patient visit. CONCLUSIONS: Medical consultations can bring about long-lasting positive changes in prognostically unfavourable cognitions and anxiety. These changes appear to be related to a better outcome of IBS.

Changing preventive practice: a controlled trial on the effects of outreach visits to organise prevention of cardiovascular disease.

OBJECTIVES: To assess the effects of outreach visits by trained nurse facilitators on the organisation of services used to prevent cardiovascular disease. To identify the characteristics of general practices that determined success. DESIGN: A non-randomised controlled trial of two methods of implementing guidelines to organise prevention of cardiovascular disease: an innovative outreach visit method compared with a feedback method. The results in both groups were compared with data from a control group. SETTING AND SUBJECTS: 95 general practices in two regions in The Netherlands. INTERVENTIONS: Trained nurse facilitators visited practices, focusing on solving problems in the organisation of prevention. They applied a four step model in each practice. The number of visits depended on the needs of the practice team. The feedback method consisted of the provision of a feedback report with advice specific to each practice and standardised instructions. MAIN OUTCOME MEASURES: The proportion of practices adhering to 10 different guidelines. Guidelines were on the detection of patients at risk, their follow up, the registration of preventive activities, and teamwork within the practice. RESULTS: Outreach visits were more effective than feedback in implementing guidelines to organise prevention. Within the group with outreach visits, the increase in the number of practices adhering to the guidelines was significant for six out of 10 guidelines. Within the feedback group, a comparison of data before and after intervention showed no significant differences. Partnerships and practices with a computer changed more. CONCLUSION: Outreach visits by trained nurse facilitators proved to be effective in implementing guidelines within general practices, probably because their help was practical and designed for the individual practice, guided by the wishes and capabilities of the practice team.

Barriers to preventive care in general practice: the role of organizational and attitudinal factors.

BACKGROUND: There are numerous barriers to preventive care. In this paper we focus on barriers related to the organization of preventive services and to the general practitioners' (GPs') attitudes and self-efficacy expectations. The prevention of cardiovascular disease was taken as a case study. AIM: To study the organization of cardiovascular services and the attitudes and self-efficacy expectations of GPs, the relationships that exist between these factors, and the influence of practice and provider characteristics. METHOD: A survey was conducted among 95 general practices with 195 GPs. RESULTS: Few practices were sufficiently well-organized to provide effective preventive services. Seventy per cent of the GPs had positive self-efficacy expectations. Thirty to fifty per cent had positive attitudes. Few relationships were found between the organization of services and positive attitudes or expectations. Moreover, few relationships were found between practice and provider characteristics and barriers studied. List size played some role in the presence of barriers. CONCLUSION: Barriers to prevention exist. Even a positive attitude or self-efficacy expectation does not automatically coincide with a practice organization equipped for prevention. Changing attitudes is probably not enough. Efforts have to be directed at the organization of services.

The relationship between complaint-related cognitions in referred patients with irritable bowel syndrome and subsequent health care seeking behaviour in primary care.

BACKGROUND: It is generally accepted that it is important to explore patients' beliefs and fears about the meaning of their symptoms during medical consultations. OBJECTIVE: To discover how referral behaviour of GPs and attention to dysfunctional cognitions of medical specialists affect the subsequent health care seeking behaviour of patients with irritable bowel syndrome. METHOD: Questionnaires were distributed to GPs and to doctors and patients at an outpatient clinic in the University Hospital of Nijmegen. RESULTS: The results of the present study indicate that doctors' attention to the complaint-related cognitions of IBS-patients is also related to a reduced use of medical health services in primary care. On the other hand, when referred IBS-patients continue to attribute their complaints to a somatic abnormality even after such an abnormality has been ruled out through extensive physical examinations, the subsequent use of medical health services in primary care is likely to increase. Moreover, GPs' referral behaviour appears to strengthen these dysfunctional somatic attributions in IBS-patients. CONCLUSION: These unfavorable consequences might be avoided by handling cognitions and anxiety more specifically during medical consultations in primary as well as secondary care.

Doctor-dependent changes in complaint-related cognitions and anxiety during medical consultations in functional abdominal complaints.

This study explored the changes in complaint-related cognitions and anxiety of 110 consecutive out-patients with functional abdominal complaints (irritable bowel syndrome), during a series of consultations. Patients' anxiety, fear of cancer, somatic attribution concerning intestines or stomach and catastrophizing cognitions appeared to diminish significantly during the consulting period. Positive changes in patients' psychological attribution and somatic attribution appeared to be related to doctors' correct perceptions of these attributions. Catastrophizing cognitions diminished significantly more when patients saw the same doctor throughout the consultations. As changes in attributions and catastrophizing cognitions appeared to be related to doctor-patient interaction, it is conceivable that doctors could learn to influence cognitions even more.

Doctors' perception of patients' cognitions and complaints in irritable bowel syndrome at an out-patient clinic.

Functional abdominal complaints (IBS) are widespread in the general population, especially among women. Non-organic dimensions of the complaint such as complaint-related cognitions and behaviour appear to be related to the prognosis. The prognosis could possibly be improved by changing these factors during medical consultations. Therefore, doctors have to perceive patients' cognitions and behaviour. But, do they perceive them correctly? One hundred and twenty patients with functional abdominal complaints referred to an out-patient clinic for internal medicine completed a questionnaire about their complaints and their complaint-related cognitions, behaviour, and anxiety prior to the first consultation. After the first consultation, doctors completed a similar questionnaire indicating their perceptions of patients' cognitions, anxiety, behaviour, and complaints. Complaints were perceived better than cognitions, anxiety, and behaviour. Doctors underestimated patients' expectations and secondary complaints and overestimated patients' pain-related attributions, and their catastrophizing and self-efficacy cognitions.

Prevalence of left ventricular hypertrophy as assessed by electrocardiogram in treated hypertensive persons in general practice.

Many studies have paid attention to the prevalence of left ventricular hypertrophy (LVH) as assessed by electrocardiogram (ECG) in hypertensive patients. Patients with ECG-LVH show a considerably higher risk of cardiovascular morbidity and mortality than patients without ECG-LVH. This paper describes the prevalence of LVH and the relation between LVH, age, sex and BP. ECG, BP, treatment, duration of hypertension, body mass index and total serum cholesterol were recorded. The dimension of LVH was computed in accordance with the Minnesota Code. One of five hypertensive patients (21%) had LVH with or without repolarisation abnormalities. LVH based on high QRS voltages only was found more often in men. LVH with repolarisation abnormalities was more frequent in elderly patients. LVH was found more often in the highest SBP categories (SBP > 160 mmHg) and in the highest DBP categories (DBP > 105 mmHg). A logistic regression analysis showed the influence on the occurrence of LVH of the following parameters: being male, age > 65 years, SBP > 160 mmHg and DBP > 105 mmHg.

Relationship between the working styles of general practitioners and the health status of their patients.

The aim of this study was to relate the working style of general practitioners to the health status of a sample of their patients. From a large regional sick fund forming part of the national health insurance system in the Netherlands a stratified sample was taken of general practitioners with at least 1000 patients on their list, taking into account the degree or urbanization of the area in which they practised and their annual referral rates to specialists. These 75 general practitioners were observed for two days in their surgeries by trained doctors and rated according to criteria defined beforehand. Taking into account these ratings and the annual figures from the sick fund for prescribing selected drugs and referrals to specialists, the general practitioners were classified into styles of practice - integrated, interventionist or minimal diagnostic. Twenty randomly selected women, aged 50-65 years, from each general practitioner's list, were interviewed and examined by independent doctors. The patients of general practitioners with the integrated practice style appeared to feel more healthy and to have more realistic expectations about the possibilities of professional help for common ailments. They tended to visit their doctor less frequently and to have fewer symptoms. The results showed an association between the quality of general practitioners and patients' health, and it may therefore be concluded that good general practitioners can further the health and well being of their patients.

Medical versus behavioural skills: an observation study of 75 general practitioners.

This study deals with a replication of a previous research project on the correlation between medical and behavioural skills of general practitioners. The PREVARA observation schedule was used to assess these skills of 75 general practitioners. Fifteen surgery contacts were tape-recorded for each GP and were rated by trained observers. The study shows that fundamental dimension underlies the surgery behaviour of the GP: the various skills appear to be equally developed. More specifically, a positive correlation was found between performing obligatory physical examination and paying attention to psychosocial aspects. The results are discussed in the context of the evaluation of the vocational training and medical audit of GPs.
