[Variability in the control of oral anticoagulant therapy between primary care and hospital in Albacete (2009)].

Background: After taking control of oral anticoagulant therapy in our health center it became necessary to detect possible differences with regard to hospital monitoring. The aim of our study was to determine the variability in the International Normalized Ratio (INR) values of patients on oral anticoagulant therapy (OAT), and the possible relation to control in primary care or hospital.

Methods: We analyzed the last 6 controls of 291 patients in an urban health centre in routine control by OAT.
