In a prospective cohort study the influence of self-monitoring of the International
Normalized Ratio (INR) was examined on 100 consecutive patients for a period of 6
months. Quality of life changed in a positive way. Independence and better organization
of vacation and spare time were the most frequently mentioned advantages of the new
method. Quality of anticoagulation by using a self-monitoring device was improved
compared to the values before using the self-monitoring device. For measuring the
INR, the usage of a portable monitor as the primary method can be recommended in selected
patients receiving oral long-term anticoagulation.
