Update of the Situation-specific Theory for health management in heart failure: Delphi study

the updated theory offers a better understanding of the factors that can influence the health control of individuals with heart failure and, although the focus of the theory is in the outpatient setting, it assumes the possibility of its application in other settings. The Delphi technique proved to be useful for theoretical validation, considering the specificity of the theme; however, the response time of the experts can be slow, which tends to impact the time to complete the study.
