Fatigue in CHFFatigue in CHFFatigue: a significant predictor for developing Fatigue: a significant predictor for developing severe CHF severe CHF (Ekman, et al., 2005)(Ekman, et al., 2005)
Fatigue intervention requires attention Fatigue intervention requires attention
Currently CHF patients may receive fatigue Currently CHF patients may receive fatigue management education before discharge but management education before discharge but they may not have opportunity to access the they may not have opportunity to access the education after going home.education after going home.

Participants learned and used the strategy of how to pace themselves in daily life more than other strategies because of its immediate result.
The strategy to take more time to implement was least applied.
Use of assistive devices became common strategies – contradictory to other studies using younger patients– because the study participants were older and were
more disabled

Clinical ImplicationsClinical Implications
The use of a client-centered approach to OT practice The use of a client-centered approach to OT practice has developed rapidly during the last decadehas developed rapidly during the last decade
E-therapyE-therapy is an application of client-centered practice is an application of client-centered practice– Make services available to the client at the time of greatest need– Allow clients more flexibility in their daily schedule – The therapist as a facilitator enable the client to generate
strategies of coping
Therapists can efficiently deliver therapy through the internet after the initial personal evaluation and training with the clients.

ConclusionConclusion
The e-therapy program is feasible and effective in maintaining fatigue severity, overall fatigue impact on functions, level of activities & mental health among older adults with CHF, if they were motivated, have means, and skills. In this technology age, e-therapy may be actualized in the near future.
The further study is strongly needed to provide clear evidence of effectiveness of e-therapy including cost effectiveness.
