The impact of the Chaser application on the medical knowledge of cardiac patients


Background: Cardiological patients are frequently treated with anticoagulation therapy. There are benefits, but also an increased risk of bleeding, which may be life-threatening. Chaser is a mobile application, which was aimed to educate patients taking anticoagulants to improve patients’ knowledge and further adherence. Objective: The aim of this study was to evaluate Chaser in patients taking anticoagulant medica-tions, check the application’s usefulness, and whether it contributes to the increase of patients' knowledge of anticoagulant treatment. Methods: Consecutive 50 participants were recruited for the study and were access to the applica-tion. Inclusion criteria were being on anticoagulant therapy and being able to use a mobile phone with Internet access. All patients have had Chaser installed on their phones for at least 24 hours. The patients were given a questionnaire two times: before intervention and one day later. It was created by the study authors and tests the knowledge of patients in the field of cardiology - anticoagulation treatment, symptoms, and diseases. Results: There were 29 (58%) males and 21 (42%) females. The mean age of the patients was 66 years old. All patients suffered from at least one cardiological disease, which required anticoagu-lation. The majority (29 of 50 (62%)) participants improved their score and 18 of 50 (36%) oth-er participants had the same result. The rest had worse scores. Conclusions: The Chaser has the potential to increase patient education and self-care in the com-plex treatment of antiplatelet therapy. There is a possibility that this will contribute to the effec-tiveness and safety of the treatment.
