Heart Failure Activity Coach Study

Brief Summary

Detailed Description

Study design: ---------------- The activity coach is to be developed using a scientific approach based on the Medical Research Council guidelines, including a small pilot (ethical approval Dnr 2020-01444) which is to be published separately. This is the first step and the second step is the randomized controlled pilot study (pilot-RCT), to be performed in a primary care setting in Sweden (ethical approval Dnr 2021-05366-01). The purpose is to test the newly developed application (app) called the activity coach, to see if it can improve physical activity, health and quality of life in physically inactive hert failure (HF) patients, but more importantly test the study design and recruitment process, as well as outcomes for a future efficacy RCT. The patients included will already be equipped with the mHealth tool Optilogg, and then screened for physical inactivty through a self-report question (Blomqvist, 2020, ESC Heart Fail, Utility of single-item questions to assess physical inactivity in patients with chronic heart failure), and then randomized to either receive or not receive the activity coach app. After randomization the patients will be equipped with an accelerometer for one week. The intervention will go on for 12 weeks, and week twelve the patients will once again carry an acceleroemter. At baseline demographical data will be recorded, as well as data on co-morbidities and pharmacological treatment. Patients will from a pre-specified list select two goals relating to physical activity that they wish to attain. After 12 weeks they will evaluate the subjective goal attainment on a five level ordinal scale ranging from -2 to 2. At weeks 1 and 12 they will also report health related quality of life using the Kansas City Cardiomyopathy Questionnaire. Intervention --------------- The Optilogg system is based around a touch screen computer (tablet), and the activity coach app runs on this screen. During the first week the patient receives specific education about physical activity and HF on the screen After the first week the patient is expected to be motivated to engage in physical activity and a short slideshow on the screen of the activity coach illustrates how the person using the system can manually register physical activity on the tablet interface. The registered activity trends can be viewed on the screen.At the end of every week the user will receive a weekly summary on screen with the option to set a goal for next week. The goal functionality is optional so that anyone who feels negative stress from the goal, can simply select to not have a goal. All patients will have access to telephone support during office hours for technical assistance with Optilogg and/or the activity coach.
