Use of Log Data to Evaluate a Heart Failure Telemonitoring and Persuasive Coaching Technology

University of Twente Research Information

Use of Log Data to Evaluate a Heart FailureTelemonitoring and Persuasive Coaching Technology[ BACKGROUND ]Integrating persuasive coaching [1] in a telemonitoring technology is a potential solution to provide self-management support to patients living with Chronic Congestive Heart Failure.[ METHOD ]A pilot study was conducted to determine the use, usability, and usefulness for practice of iMediSense. Each patient (n=25) used iMediSense daily for 2 months. To evaluate the use of the system, log data was used within a mixed-methods approach, also including interviews with patients (n=25), caregivers (n=7; HF nurses, cardiologists, GP), and stakeholders (n=5; developer, product owner, nancer and facilitator), as wel as usability tests (think-aloud method) of the patients interface (n=10).[ CONCLUSION ]Log data can provide relevant evidence to understand the use of technologies, focusing on data that is useful to provide effective support [3]. The use of log data in research can be effective for evaluation purposes but also to guide development by alowing further understanding and improvement in terms of persuasiveness.[ RESULTS ]We observed that:a] adherence rate was very high (90%)d b] most common navigation route showed a tunneled and reduced way to self-monitorc] certain features of iMediSense were barely used by the patients, such as the message functiond] usage could notably vary and represent distinct patients’ needs and goalsFloor Sieverink1 , Robin Wesselink2, Roberto Rafael Cruz-Martínez1, and Lisette van Gemert-Pijnen1 1 Psychology, Health & Technology, University of Twente, Enschede, The Netherlands2 Cardiology, Heart Center, Academic Medical Center, Amsterdam, The Netherlands[ AIM ] In this poster we propose that log data analysis [2] is a method that facilitates the integration of persuasive coaching and telemonitoring, and present a case study based on Heart Failure and the iMediSense technology as an example.a]b]c] d]{f.sieverink; r.cruzmartinez; j.vangemert-pijnen}@utwente.nlr.wesselink@amc.uva.nlKey references1.
