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.
