We began providing comprehensive cardiac rehabilitation for congestive heart failure (CHF) in 2014 at our institution, using an original pamphlet and heart failure notebook to provide life guidance for CHF. However, the life guidance rate was lower in 2017 (61%) than it was in 2014 (77%). The objective of this study was to investigate the awareness of life guidance among nurses. We administered a questionnaire survey regarding life guidance to 28 nurses in December 2018. Among the 27 respondents, 26 nurses (96%) had high motivation and 21 (80%) felt a sense of accomplishment. Responses to the “most important point in life guidance” were “understanding living condition” by 14 nurses, “heart failure notebook” by 9 nurses, and “guidance using the pamphlet” by 6 nurses. Fifteen nurses (58%) felt that the guidance had become routine in nature, and 5 nurses (19%) were worried about their instruction. The nurses were motivated to provide life guidance, but they also felt that the guidance had become routine because they had been providing the same guidance for many years. We consider that the factors related to the lower life guidance rate are the routine/repetitive nature of the guidance and concerns about instruction. Going forward, we need to review the content of the guidance and the teaching approach.
