Abstract
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia with serious potential consequences when left untreated. For timely treatment, early detection is imperative. We explored how new AF is detected in patients aged ≥ 65 years in Dutch healthcare. METHODS The study cohort consisted of 9526 patients from 49 Dutch general practices in the usual-care arm of the Detecting and Diagnosing Atrial Fibrillation study. We automatically extracted data from the electronic medical records and reviewed individual records of patients who developed AF. Patient selection started in 2015, and data collection ended in 2019. RESULTS We included 258 patients with newly diagnosed AF. In 55.0% of the patients, the irregular heartbeat was first observed in general practice and in 16.3% in the cardiology department. Cardiologists diagnosed most cases (47.3%), followed by general practitioners (GPs; 33.7%). AF detection was triggered by symptoms in 64.7% of the patients and by previous stroke in 3.5%. Overall, patients aged 65-74 years more often presented with symptoms than those aged ≥ 75 years (73.5% vs 60.6%; p = 0.042). In 31.5% of the patients, AF was diagnosed incidentally ('silent AF'). Silent-AF patients were on average 2 years older than symptomatic-AF patients. GPs less often diagnosed silent AF than symptomatic AF (21.0% vs 39.0%; p = 0.008), whereas physicians other than GPs or cardiologists more often diagnosed symptomatic AF than silent AF (34.6% vs 11.9%; p < 0.001). Most diagnoses were based on a 12-lead electrocardiogram (93.8%). CONCLUSION Diagnosing AF is a multidisciplinary process. The irregular heartbeat was most often detected by the GP, but cardiologists diagnosed most cases. One-third of all newly diagnosed AF was silent.

How do Dutch general practitioners detect and diagnose atrial fibrillation? Results of an online case vignette study. BMC FAMILY PRACTICE 2019; 20:175. [PMID: 31837709 PMCID: PMC6911277 DOI: 10.1186/s12875-019-1064-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Accepted: 11/29/2019] [Indexed: 11/10/2022]
Abstract
Background Detection and treatment of atrial fibrillation (AF) are important given the serious health consequences. AF may be silent or paroxysmal and remain undetected. It is unclear whether general practitioners (GPs) have appropriate equipment and optimally utilise it to detect AF. This case vignette study aimed to describe current practice and to explore possible improvements to optimise AF detection. Methods Between June and July 2017, we performed an online case vignette study among Dutch GPs. We aimed at obtaining at least 75 responses to the questionnaire. We collected demographics and asked GPs’ opinion on their knowledge and experience in diagnosing AF. GPs could indicate which diagnostic tools they have for AF. In six case vignettes with varying symptom frequency and physical signs, they could make diagnostic choices. The last questions covered screening and actions after diagnosing AF. We compared the answers to the Dutch guideline for GPs on AF. Results Seventy-six GPs completed the questionnaire. Seventy-four GPs (97%) thought they have enough knowledge and 72 (95%) enough experience to diagnose AF. Seventy-four GPs (97%) could order or perform ECGs without the interference of a cardiologist. In case of frequent symptoms of AF, 36–40% would choose short-term (i.e. 24–48 h) and 11–19% long-term (i.e. 7 days, 14 days or 1 month) monitoring. In case of non-frequent symptoms, 29–31% would choose short-term and 21–30% long-term monitoring. If opportunistic screening in primary care proves to be effective, 83% (58/70) will support it. Conclusions Responding GPs report to have adequate equipment, knowledge, and experience to detect and diagnose AF. Almost all participants can order ECGs. Reported monitoring duration was shorter than recommended by the guideline. AF detection could improve by increasing the monitoring duration.

Abstract
BACKGROUND The electrocardiogram (ECG) has become a popular tool in primary care. The clinical value of the ECG depends on the appropriateness of the indication and the interpretation skills of the general practitioner (GP). OBJECTIVES To describe the use of electrocardiography in primary care and to assess the performance of GPs in interpreting ECGs and making subsequent management decisions. METHODS Three hundred ECGs, recorded during daily practice in symptomatic patients by 14 GPs who regularly perform electrocardiography, were selected. Corresponding data of the indications, interpretations and subsequent management actions were extracted from the associated medical records. A panel consisting of an expert GP and a cardiologist reviewed the ECGs and specified their agreement with the findings and actions of the study GPs. RESULTS The most common indications were suspicion of a rhythm abnormality (43.7%), ischaemic heart disease (42.7%) and patient reassurance (14.3%). The study GPs interpreted 53.3% of the ECGs as showing no (new or acute) abnormality, whereas supraventricular rhythm disorders (12.3%), conduction disorders (7.7%) and repolarisation disorders (7.0%) were the most frequently reported pathological findings. Overall, the expert panel disagreed with the interpretations of the study GPs in 16.2% of cases, and with the GPs' management actions in 11.7%. Learning goals for GPs performing electrocardiography could be formulated for acute coronary syndrome, rhythm disorders, pulmonary embolism, reassurance, left ventricular hypertrophy and premature ventricular complexes. CONCLUSION GPs who feel competent in electrocardiography performed well in the opinion of the expert panel. We formulated various learning objectives for GPs performing electrocardiography.

Abstract
BACKGROUND Performing electrocardiography is common in general practice, but the quality of indication setting and diagnostic accuracy have been disputed. OBJECTIVES To assess the competence of general practitioners (GPs) in their decision-making process with regard to recording and interpreting an electrocardiogram (ECG) and evaluating the relevance of the result for management. METHODS An online case vignette survey was performed among GPs and cardiologists (in 2015). Nine cases describing situations for which Dutch clinical guidelines recommend or advise against recording an ECG were presented. In each case, the participant had to make choices on recording an ECG, interpreting it, and using the result in a management decision. The reference standard for each ECG diagnosis was set by the expert author team. RESULTS Fifty GPs who interpret ECGs themselves, eight GPs who do not and 12 cardiologists completed the survey. Adherence to guidelines recommending an ECG was high for suspected atrial fibrillation, suspected arrhythmia present during consultation, including bradycardia, but much lower for progressive heart failure and stable angina. Diagnostic accuracy of GPs was best in atrial fibrillation (96%), sick sinus syndrome (85%) and old myocardial infarction (82%), but poor in left anterior fascicular block (16%) and incomplete right bundle branch block (10%). GPs often acknowledged the low relevance of the results of a non-indicated ECG. CONCLUSION GPs do not fully adhere to Dutch cardiovascular guidelines on indications for recording ECGs. Diagnostic accuracy was high for atrial fibrillation, sick sinus syndrome and old myocardial infarction and poor for left anterior fascicular block and incomplete right bundle branch block.

Abstract
OBJECTIVE To identify factors associated with appropriate knowledge about the indications for drugs prescribed to older patients on polypharmacy. DESIGN Cross-sectional study. METHOD In a primary care setting, patients aged 60 years and over who were taking five or more prescribed drugs simultaneously were asked about their medication by conducting home interviews and postal questionnaires. Multiple logistic regression analysis was used to evaluate the association between medication knowledge and explanatory variables such as medication use, sex, age, residential status and educational level. RESULTS Seven hundred and fifty-four participants, mean age 73.2 years, reported an average daily intake of nine (SD 3.0) prescribed drugs. Only 15% of the patients were able to recall the indication for each of their prescribed drugs. Variables that were negatively associated with correct reporting of all indications were: taking many prescribed drugs (≥ 10 vs. ≤ 5 drugs: odds ratio (OR) 0.05), age 80 years or over (vs. 60-69 years: OR 0.47) and male sex (vs. females: OR 0.53). Patients living with a partner were more knowledgeable than patients living alone (OR 2.11). We did not find an association with educational level. CONCLUSION Among older patients using five or more prescribed drugs, there was little understanding of the indications for their drugs, especially among patients taking the highest number of drugs, patients aged 80 years or over, and men. Patients living independently with a partner were more knowledgeable than others.

Abstract
BACKGROUND General practitioners can safely exclude pulmonary embolism (PE) by using the Wells PE rule combined with D-dimer testing. OBJECTIVE To compare the accuracy of a strategy using the Wells rule combined with either a qualitative point-of-care (POC) D-dimer test performed in primary care or a quantitative laboratory-based D-dimer test. METHODS We used data from a prospective cohort study including 598 adults suspected of PE in primary care in the Netherlands. General practitioners scored the Wells rule and carried out a qualitative POC test. All patients were referred to hospital for reference testing. We obtained quantitative D-dimer test results as performed in hospital laboratories. The primary outcome was the prevalence of venous thromboembolism in low-risk patients. RESULTS Prevalence of PE was 12.2%. POC D-dimer test results were available in 582 patients (97%). Quantitative test results were available in 401 patients (67%). We imputed results in 197 patients. The quantitative test and POC test missed one (0.4%) and four patients (1.5%), respectively, with a negative strategy (Wells ≤ 4 points and D-dimer test negative) (P = 0.20). The POC test could exclude 23 more patients (4%) (P = 0.05). The sensitivity and specificity of the Wells rule combined with a POC test were 94.5% and 51.0% and, combined with a quantitative test, 98.6% and 47.2%, respectively. CONCLUSIONS Combined with the Wells PE rule, both tests are safe to use in excluding PE. The quantitative test seemed to be safer than the POC test, albeit not statistically significant. The specificity of the POC test was higher, resulting in more patients in whom PE could be excluded.

Abstract
BACKGROUND The ankle brachial index (ABI) is related to risk of cardiovascular events independent of the Framingham risk score (FRS). The aim of this study was to develop and evaluate a risk model for cardiovascular events incorporating the ABI and FRS. DESIGN An analysis of participant data from 18 cohorts in which 24,375 men and 20,377 women free of coronary heart disease had ABI measured and were followed up for events. METHODS Subjects were divided into a development and internal validation dataset and an external validation dataset. Two models, comprising FRS and FRS + ABI, were fitted for the primary outcome of major coronary events. RESULTS In predicting events in the external validation dataset, C-index for the FRS was 0.672 (95% CI 0.599 to 0.737) in men and 0.578 (95% CI 0.492 to 0.661) in women. The FRS + ABI led to a small increase in C-index in men to 0.685 (95% CI 0.612 to 0.749) and large increase in women to 0.690 (95% CI 0.605 to 0.764) with net reclassification improvement (NRI) of 4.3% (95% CI 0.0 to 7.6%, p = 0.050) and 9.6% (95% CI 6.1 to 16.4%, p < 0.001), respectively. Restricting the FRS + ABI model to those with FRS intermediate 10-year risk of 10 to 19% resulted in higher NRI of 15.9% (95% CI 6.1 to 20.6%, p < 0.001) in men and 23.3% (95% CI 13.8 to 62.5%, p = 0.002) in women. However, incorporating ABI in an improved newly fitted risk factor model had a nonsignificant effect: NRI 2.0% (95% CI 2.3 to 4.2%, p = 0.567) in men and 1.1% (95% CI 1.9 to 4.0%, p = 0.483) in women. CONCLUSIONS An ABI risk model may improve prediction especially in individuals at intermediate risk and when performance of the base risk factor model is modest.

Abstract
Background Open access echocardiography has been evaluated in the United Kingdom, but hardly in the Netherlands. The echocardiography service of the SHL-Groep in Etten-Leur was set up independently from the regional hospitals. Cardiologists not involved in the direct care of the participating patients evaluated the echocardiograms taken by ultrasound technicians. Aims We estimated the reduction in the number of referrals to regional cardiologists, the adherence of the general practitioners (GPs) to the advice of the evaluating cardiologist, GPs’ opinion on the benefit of the echocardiography service and GPs’ adherence to the diagnostic protocol advocated in the Dutch clinical guideline for heart failure. Methods A prospective cohort study was performed. Patients were included from April 2011 to April 2012 (N = 155). Data from application forms (N = 155), echocardiography results (N = 155) and telephone interviews with GPs (N = 138) were analysed. Results GPs referred less patients to the cardiologist than they would have done without echocardiography available (92 % vs. 34 %, p < 0.001). They treated more patients by themselves (62 % vs. 10 %, p < 0.001). Most GPs (81 %) followed the advice presented on the echocardiogram result. Most GPs (82 %) found the service had clinical benefit for the patient. Sixty two percent of echocardiography requests met the criteria of the Dutch clinical guideline for heart failure. Conclusion Open access echocardiography saved referrals to the cardiology department, saved time, and enabled GPs to treat more patients by themselves. Adherence to diagnostic guidelines for heart failure was suboptimal.

Abstract
BACKGROUND Polypharmacy in older people should be addressed by an annual review of the chronic medication. In the PIL-study this was done by an integrated approach by GP, practice nurse, pharmacist, specialist and patient. All patients were first visited at home by the practice nurse. RESEARCH QUESTIONS What 'over the counter' (OTC) medications do polypharmacy patients use? Do they know the indications of the prescribed medication? Does medication use according to the patient match with medication use according to the records of GP and pharmacist? METHOD Inclusion criteria were: age 60 years or older, daily use of five or more chronic medications, mental competence, and adequate command of the Dutch language. All patients were visited at home by the practice nurse, who made an inventory of the actual drug use. RESULTS Five hundred fifty patients used a total of 5576 drugs, including 527 (9.4%) OTC medication. Patients knew the indication of 64% of the prescribed medication. The number of prescribed drugs that a patient actually used did not match the numbers known to GP and pharmacist. In 60.4% of all medication prescriptions there was complete agreement between GP, pharmacist and patient. On a patient level agreement was 18.7%. CONCLUSIONS Home visits by the nurse practitioner to make an inventory of the medication as reported by the patient seem to have an added value.

Abstract
BACKGROUND In patients initially suspected of deep venous thrombosis (DVT) the diagnosis can be confirmed in approximately 10 to 30% of cases. For the majority of patients this means that eventually an alternative diagnosis is assigned. OBJECTIVE To assess the frequency distribution of alternative diagnoses and subsequent management of patients in primary care after initial exclusion of DVT. In addition, assess the value of ultrasound examination for the allocation of alternative diagnoses. METHODS Data were recorded by general practitioners alongside a diagnostic study in primary care in the Netherlands (AMUSE). Additional data were retrieved from a three-month follow-up questionnaire. A descriptive analysis was performed using these combined data. RESULTS The most prevalent diagnoses were muscle rupture (18.5%), chronic venous insufficiency (CVI) (14.6%), erysipelas/cellulitis (12.6%) and superficial venous thrombosis (SVT) (10.9%). Alternative diagnoses were based mainly on physical examination; ultrasound examination (US) did not improve the diagnostic yield for the allocation of alternative diagnoses. In about 30% of all cases, a wait and see approach was used (27 to 41%). During the three-month follow-up nine patients were diagnosed with venous thromboembolic disease, three of which occurred in patients with the working diagnosis of SVT (p=0.026). CONCLUSIONS We found that after exclusion of DVT in general practice a wait and see policy in the primary care setting is uneventful for almost one third of patients, but with the alternative diagnosis of SVT, patients may require closer surveillance since we found a significant association with thrombosis in these patients.

Abstract
BACKGROUND Referral for ultrasound testing in all patients suspected of DVT is inefficient, because 80-90% have no DVT. OBJECTIVE To assess the incremental cost-effectiveness of a diagnostic strategy to select patients at first presentation in primary care based on a point of care D-dimer test combined with a clinical decision rule (AMUSE strategy), compared with hospital-based strategies. PATIENTS/METHODS A Markov-type cost-effectiveness model with a societal perspective and a 5-year time horizon was used to compare the AMUSE strategy with hospital-based strategies. Data were derived from the AMUSE study (2005-2007), the literature, and a direct survey of costs (2005-2007). RESULTS OF BASE-CASE ANALYSIS Adherence to the AMUSE strategy on average results in savings of euro138 ($185) per patient at the expense of a very small health loss (0.002 QALYs) compared with the best hospital strategy. The iCER is euro55 753($74 848). The cost-effectiveness acceptability curves show that the AMUSE strategy has the highest probability of being cost-effective. RESULTS OF SENSITIVITY ANALYSIS Results are sensitive to decreases in sensitivity of the diagnostic strategy, but are not sensitive to increase in age (range 30-80), the costs for health states, and events. CONCLUSION A diagnostic management strategy based on a clinical decision rule and a point of care D-dimer assay to exclude DVT in primary care is not only safe, but also cost-effective as compared with hospital-based strategies.

Abstract
Objective. Guidelines on primary prevention of cardiovascular disease (CVD) emphasize identifying high-risk patients for more intensive management, but patients' misconceptions of risk hamper implementation. Insight is needed into the type of patients that general practitioners (GPs) encounter in their cardiovascular prevention activities. How appropriate are the risk perceptions and worries of patients with whom GPs discuss CVD risks? What determines inappropriate risk perception? Method. Cross-sectional study in 34 general practices. The study included patients aged 40 to 70 years with whom CVD risk was discussed during consultation. After the consultation, the GPs completed a registration form, and patients completed a questionnaire. Correlations between patients' actual CVD risk and risk perceptions were analyzed. Results. In total, 490 patients were included. In 17% of the consultations, patients were actually at high risk. Risk was perceived inappropriately by nearly 4 in 5 high-risk patients (incorrect optimism) and by 1 in 5 low-risk patients (incorrect pessimism). Smoking, hypertension, and obesity were determinants of perceiving CVD risk as high, whereas surprisingly, diabetic patients did not report any anxiety about their CVD risk. Men were more likely to perceive their CVD risk inappropriately than women. Conclusion. In communicating CVD risk, GPs must be aware that they mostly encounter low-risk patients and that the perceived risk and worry do not necessarily correspond with the actual risk. Incorrect perceptions of CVD risk among men and patients with diabetes were striking.

Abstract
OBJECTIVES In an urban region in the Netherlands, general practitioners (GPs) were offered an open access echocardiographic service. We report the outcomes of the first two years of this project. METHODS GPs were given a course on the indications and restrictions for diagnostic referral as well as the interpretation of echocardiographic results. Indications were restricted to `dyspnoea', `cardiac murmur' and `peripheral oedema'. A uniform request form was developed, using ticking boxes for quick completion. The echocardiogram was performed within one week after the request. Results were interpreted by the cardiologist according to the criteria of the Dutch, European and American Societies of Echocardiography. RESULTS Sixty GPs from 43 general practices participated, covering a practice population of 130,000 persons. During a period of 24 months, 198 patients were referred. Only 1.5% of the workload of the echocardiography department was due to requests from GPs. The GPs kept well to the agreements on indications for echocardiography (91% approved reasons). An abnormal echocardiographic outcome was found in 53% of all patients. For `cardiac murmur' this was 52%, for `dyspnoea' 63%, and for `peripheral oedema' 58%. Left ventricular dysfunction was present in 49 patients (25%); diastolic dysfunction was present in most of them (39 patients, 19%). Systolic dysfunction (LVEF < 40%) was found in 19 patients (10%). Twenty patients (10%) appeared to have relevant aortic or mitral valve disease. CONCLUSION GPs did not overuse the open access echocardiographic service; they possibly used it conservatively. To prevent underdiagnosis of left ventricular dysfunction, diagnostic strategies in which electrocardiogram, NT-pro-BNP and echocardiography are combined, should be developed.

Abstract
BACKGROUND Our objective was to investigate whether a region in the south of the Netherlands (Heerlen/Kerkrade) had a high burden of cardiovascular disease in comparison with a nearby region (Maastricht) and the average Dutch population, respectively. We also wanted to determine if there are interregional differences in cardiovascular risk factor profile. DESIGN Cross-sectional study. METHODS Data from a nationwide registry (CBS) were used to analyse cardiovascular mortality in the two regions and the average in the Netherlands. Data from a primary care morbidity registration network (RNH) were used to compare cardiovascular morbidity and cardiovascular risk factors in both regions. A standardisation procedure was carried out for age and sex. Data were analysed using logistic regression analyses. RESULTS The overall cardiovascular mortality rate was higher in the Heerlen/Kerkrade region (7.8 per thousand) compared with Maastricht (6.1 per thousand, OR=1.3, 95% CI 1.2-1.5) and the average in the Netherlands (5.7 per thousand). Similarly, most cardiovascular morbidity rates for Heerlen/Kerkrade were more elevated compared with the RNH overall and with Maastricht. Prevalence rates of risk factors such as diabetes mellitus (7.2%, OR=1.5, 95% CI 1.3-1.7) and overweight (10.8%, OR= 2.0, 95% CI 1.8-2.2) were significantly higher in the Heerlen/Kerkrade region compared with Maastricht. There were no differences with regard to hypertension (15.2%, OR=1.0, 95% CI 0.9-1.1). CONCLUSION Heerlen/Kerkrade is indeed a region with a high burden of cardiovascular disease. Differences in morbidity between Heerlen/Kerkrade and Maastricht cannot be fully explained by differences in cardiovascular risk factor profile.

Abstract
BACKGROUND In spring 2002, WONCA Europe, the European Society of General Practice/Family Medicine and its Network organizations reached consensus on a 'new' European definition of general practice. Subsequently, the European General Practice Research Workshop (EGPRW) started working on a European General Practice Research Agenda. This topic was addressed during the 2002 EGPRW autumn meeting. OBJECTIVE Our aim was to explore the views of European general practice researchers on needs and priorities as well as barriers for general practice research in Europe. METHODS In seven discussion groups, 43 general practice researchers from 18 European countries had to answer the following questions. (i) What major topics should be included in a research agenda for general practice in your country? (ii) What are the barriers to adequate implementation of general practice research in your country? Group answers were listed and subsequently categorized by two authors. RESULTS Research on 'clinical issues' (common diseases, chronic diseases, etc.), including diagnostic strategies, was considered to be the core content of general practice research, with primary care-based morbidity registration essential for surveillance of disease, clinical research and teaching in general practice. There was also consensus on the need for research on education and teaching. 'Insufficient funding opportunities' was perceived to be the major barrier to the development of general practice research. CONCLUSIONS These findings could be used as a basis for national checklists of 'content of' and 'conditions for' general practice research. European general practice research training programmes should be developed further.

Abstract
Peripheral vascular disease is a manifestation of atherosclerosis and may occur with or without signs or symptoms. The local prognosis is worse with signs or symptoms. The concomitant atherosclerosis in heart and brain is responsible for long-term morbidity and mortality. Absence of signs and symptoms almost excludes peripheral vascular disease, but for the diagnosis an ankle-brachial index is mandatory. This implies a protocol in general practice. Treatment of peripheral vascular disease consists of advice on cardiovascular risk factors, stopping smoking, walking exercises, and foot care. For peripheral vascular disease, anti-thrombotic medication is advised.

Abstract
OBJECTIVE Asymptomatic peripheral arterial occlusive disease (PAOD) is a common atherosclerotic disorder among the elderly population. Scarce data are available on the risk of nonfatal and fatal cardiovascular diseases in these subjects. We investigated cardiovascular morbidity and mortality of asymptomatic PAOD subjects. STUDY DESIGN AND SETTING A sample of 3649 subjects (40-78 years of age) was selected in collaboration with 18 general practice centers and followed up after the initial screening (mean follow-up time 7.2 years). Asymptomatic PAOD was determined by means of the ankle-brachial pressure index (ABPI). Main outcome measures were nonfatal cardiovascular events and mortality. RESULTS Cox proportional hazard models showed that asymptomatic PAOD was significantly associated with cardiovascular morbidity (hazard ratio [HR] 1.6, 95% confidence interval [CI] 1.3-2.1), total mortality (HR 1.4, 95% CI 1.1-1.8), and cardiovascular mortality (HR 1.5, 95% CI 1.1-2.1). CONCLUSION Asymptomatic PAOD is a significant predictor of cardiovascular morbidity and mortality. In high-risk subjects, measurement of the ABPI provides valuable information on future cardiovascular events.
