In a previously published study of this multi-professional programme (Lofvenmark et al. 2011) we showed that the knowledge about CHF increased in family members in both IG and CG, but significantly more in IG, which is consistent with other studies (Duhamel et al. 2007, Franzen-Dahlin et al. 2008). Other studies have shown that lack of knowledge may lead to anxiety (Stewart et al. 2000) and cause worries (Pihl et al. 2010).
