Self-management of oral anticoagulation in children with congenital heart disease.
OBJECTIVE
The concept of self-management of oral anticoagulation has been shown to entail better quality of treatment than conventional management when assessed in selected adults. We have extended the concept of self-management to include children with congenital cardiac disease, hypothesizing self-management of oral anticoagulation is also possible in this subset of patients. Our aim was to assess the quality of self-management.


METHODS
We trained 14 children aged from 2.2 to 15.6 years, with a mean age of 9.7 years, and their parents, in domiciliary analysis of the International Normalized Ratio and necessary adjustment of dosage of coumarin. The curriculum for training lasted for 27 weeks, and the patients and their parents were followed for a period of up to 31 months by weekly measurement of the values obtained for the International Normalized Ratio.


RESULTS
The patients were observed over a mean of 547 days, with a range from 214 to 953 days. The patients were within the therapeutic targetted range of the International Normalized Ratio for a median of 65.5% of the time, with a range from 17.6% to 90.4%. None of the patients experienced thromboembolic or bleeding complications requiring doctoral intervention. All the patients and their parents expressed full satisfaction with the treatment.


CONCLUSIONS
Self-management of oral anticoagulation provides a good quality of treatment, which is feasible and safe in selected children with congenital cardiac disease.
