DIALOZIC - Pilot Study of a Diagnostic Pathway for Heart Failure in Rural Areas: the Contribution of Telebiology and Telemedicine (DIALOZIC)

DIALOZIC - Pilot Study of a Diagnostic Protocol for Heart Failure in Rural Areas: The Role of Telebiology and Telemedicine

Heart failure is under-diagnosed, even though it is a highly prevalent pathology. The difficulties are accentuated in areas with low medical density. The aim of this project is to demonstrate the value, in terms of diagnosing heart failure, of a Nt-Pro-BNP point of care Test (POCT)in general practices. The aim of this pilot study is to evaluate the reliability of a diagnosis pathway adapted to a low medical density region.

Detaljeret beskrivelse

Heart failure is a frequent pathology, under-diagnosed specially in elderly patients due to sometimes non-specific clinical signs. Diagnosis requires coordination between primary care, biology platforms and cardiology teams for cross-disciplinary management. This is not easy to achieve in areas with a low medical density, and the challenge is to propose care pathways adapted to the region, to avoid patients losing out in these Brefterritoires. This multicentric study, using a "here/elsewhere" and "before/after" format, will examine the benefits of capillary NT-pro-BNP POCT directly available by the general practitioner on the basis of warning signs. A coordinated care pathway is set up with local resources. If the Nt-pro-BNP is above the age adapted exclusion cut-off value, the patient receives multi-professional support for the diagnosis and follow-up of diagnosed heart failure via local cardiologists. If an appointements with a cardiologist could not be obtained within 3 months, a fast-echo will be performed by a clinician trained in ultrasound methods. The fast echo, ECG and clinical data will be analyzed using teleexpertise support by a cardiologist of the Montpellier University Hospital. The patient follow-up will be performed by the general practician. A final evaluation will be performed at 1 year.
