This article, discussing family-witnessed resuscitation, is the first in a series providing nurses with information about essential aspects of critical care. Family-witnessed resuscitation is not common practice in healthcare settings, despite its well-documented benefits. Lack of implementation arises because of fear and anxiety among healthcare practitioners about the potential negative consequences for the patient, the family and themselves. However, research has suggested that addressing these concerns could positively affect practice and increase the number of cases of family-witnessed resuscitation. This article discusses the potential benefits of, and barriers to, family-witnessed resuscitation and how the practice could become increasingly adopted in healthcare settings.
