PORTALS study: similar status with eHealth and usual care
Objectives: To analyse the effect on therapeutic control and self-management skills of the implementation of self- management programmes, including eHealth by e-learning versus group training. Setting ans participants: Primary Care Thrombosis Service Center. Of the 247 oral anticoagulation therapy (OAT) patients, 63 started self-management by e-learning, 74 self-management by group training and 110 received usual care. Intervention and methods: Parallel cohort design with two randomised self-management groups (e-learning and group training) and a group receiving usual care. The effect of implementation of self-management on time in therapeutic range (TTR) was analysed with multilevel linear regression modelling. Usage of a supporting eHealth platform and the impact on self-ef cacy (Generalised Self- Ef cacy Scale (GSES)) and education level were analysed with linear regression analysis. After intervention, TTR was measured in three time periods of 6 months.
Main outcome measures: (1) TTR, severe complications,(2) usage of an eHealth platform,(3) GSES, education level.
Results: Analysis showed no significant differences in TTR between the three time periods (p=0.520), the three groups (p=0.460) or the groups over time (p=0.263). Comparison of e-learning and group training showed no signi cant differences in TTR between the time periods (p=0.614), the groups (p=0.460) or the groups over time (p=0.263). No association was found between GSES and TTR (p=0.717) or education level and TTR (p=0.107). No significant difference was found between the self- management groups in usage of the platform (0–6 months p=0.571; 6–12 months p=0.866; 12–18 months p=0.260). The percentage of complications was low in all groups (3.2%; 1.4%; 0%).
Conclusions: No differences were found between OAT patients trained by e-learning or by a group course regarding therapeutic control (TTR) and usage of a supporting eHealth platform. The TTR was similar in self-management and regular care patients. With adequate e-learning or group training, self-management seems safe and reliable for a selected proportion of motivated vitamin K antagonist patients.
