Abstract

Oral anticoagulation self-control programs have demonstrated efficiency and cost-effectiveness over recent years. This study aimed to evaluate the effectiveness of a training intervention focused on patients with antivitamin K anticoagulants included in a self-care program. For this, we made a quasi-experimental study, pretest and post-test, using a validated questionnaire with 2 measures, before and after an educational intervention about oral anticoagulation focused on patients that will initiate the self-control program in consultation. To check the patient's adherence and coagulation level, we evaluated the Rosendaal time in therapeutic rank, both before and after the intervention. One hundred fifty patients were included since the start of the self-monitoring program in our center in 2016. The mean age was 49 years (standard deviation [SD] = 17.24). The distribution by gender was 76 women and 69 men (52.4%-47.6%). The mean score for the first test was 14.61 (SD = 3.26) and the mean score for the second test was 17.01 (SD = 2.14) (P <.001). We also measured Rosendaal time in therapeutic rank, a parameter that indicates stabilization in international normalized ratio determinations and quality of the anticoagulation management. Values before and after interventions were also statistically significant (67.46 vs 70.53, P <.001). Patients' knowledge improved after the training session, with statistical significance. Despite intentional sampling, the population was homogeneous. Scoring data dispersion in the second test was significantly lower than in the first one. Time on therapeutic rank values was better after the training. We intend to adapt its content to the rest of anticoagulated patients to enhance and improve their follow-up.
