Introduction:

it recommends the prediction of the risk of bleeding during the therapeutic anticoagulation.

Objective:

design a predictive model of the control of the anticoagulant in patients treated with warfarina sódica.

Method:

it realised an explanatory and prospective study in 50 patients treated with warfarina sódica in the Educational General Hospital “Dr. Agostinho Neto” during the period 2015-2016. These grouped in a group control (n=25, those with suitable anticoagulation, INR between 2.0-3.0) and a group study (n=25, with unsuitable anticoagulation, INR < 2.0).

Results:

The most predictive factors of the effect unsatisfactory anticoagulant were: live alone and the use of drugs that interfere with more proof and intensity in the effect of the drug.

Conclusions:

it designed a predictive model of the control of the anticoagulation with warfarina, adjusted to the services of the Hospital “Dr. Agostinho Neto”
