Abstract Number: PB2427
Meeting: ISTH 2020 Congress
Background: Warfarin is an oral anticoagulant widely used for primary and secondary thromprophylaxis. It has a narrow therapeutic index and wide variability in dose-response, requiring frequent monitoring and assistance. Anticoagulation control with warfarin remains a challenge. Patients on warfarin could benefit from educational strategies focusing on changing behavior, to improve individual’s active participation in self-care and adherence to drug therapy.
Aims: To elaborate and validate the EmpoderACO, a protocol for behavioral change in patients on warfarin.
Methods: The instrument was developed as following: elaboration of the initial version of the protocol by specialists; multiple rounds of corrections of the instrument; pre-testand adaptations before releasing its final version. The relevance, adequacy and clarity of each item of the instrument were evaluated by a multiprofessional committee of judges using the E-Surv platform. The internal reliability was calculated using the content validity coefficient (CVC) of the evaluation of the judge’s committee. The pre-test involved 30 patients on warfarin assisted at an anticoagulation clinic of a university hospital in Brazil. At this phase, patients made a comprehensive evaluation of the protocol items.
Results: The self-care domains covered in the protocol were: understanding and satisfaction of treatment, reduction of adverse events; and promoting well-being and healthy habits. Overall, 34 professionals participated of the committee of judges, including: physicians, nurses, pharmacists, nutritionists, linguistsand a pedagogue. The CVC was considered satisfactory with a compliance CVC>0.91 of the items for relevance, adequacy and clarity. The clarity of the instrument assessed by the patients, in the pre-test, obtained an average CVC of 0.96.
Conclusions: The protocol EmpoderACO may contribute to the design of educational strategies to improve patients´ understanding of their own health problem and drug therapy, communication process between professionals and patients, and decision-making process.
