Utilisation des dispositifs de mesure de l’INR capillaire par les professionnels de santé en établissement d’hébergement pour personnes âgées dépendantes (EHPAD) pour la gestion des traitements antivitamine K par le médecin généraliste : une étude de faisabilité

摘要

Rationale. Surveillance of vitamin K antagonists (VKA) can be done by point-of-care INR testing.Methods. Prospective multicentric study assessing the feasibility of point-of-care INR testing performed by care givers in nursing homes for the elderly on VKA therapy.Results. During 9 months, 18 capillary INR have been performed in 9 patients (median age 90 years) in 3 different nrusing homes using the Coagucheck© XS Pro. Correlation between capillary and venous INR was good (r=0,959). All health care providers having used the device and general practitionners responsible for VKA prescription were in favour of capillary INR monitoringin nursing homes, thought to improve communication between them, patient comfort, INR surveillance and time in therapeutic range. The main impediment is the need for sufficient training of care givers in the use of the device.Conclusion. Point-of-care INR testing by care givers seems feasible in nursing homes for the elderly on VKA therapy.
