In one study [Sander 2012] it was observed that patients could easily misinterpret the information given to them in verbally description, especially when using ”modern” terms like ”bluetooth” or ”broadband” to older people. Seto  asked the patients what they know, and „most“ of the patients perceived that monitoring their blood pressure and weight helps them to manager their HF condition, but there were also patients who questioned the necessity of daily monitoring because their blood pressure had been stable [Seto 2010].
Boehme  measured different modules of HF-management like medication adherence, fluid intake or physical activity separately. They concluded that those patients who completed those modules had an increase in perceived health (+ 12=0.03; p=.045), but this observation was not significant for the modulenutrition“. [Boehme 2012]
To be active in their own care of HF increased the self-care activities and the feeling of being save and well cared with a better understanding of the own body [Lynga 2013]
