Abstract: This dissertation considers the implications of the relationship between nurses and the patient's family, when family members visit intensive care units (ICUs) following the acute admission of a relative there. In particular it explores the issues of power and control, nurses might have in this setting, the culture that supports that, and the implications this has for practice in the New Zealand context. A comprehensive literature review on the perspective of nurses in relation to relatives visiting adult intensive care units was conducted. The author concludes that nurses modify policies related to visiting access for family members to suit themselves, and the needs of their patient. Nurses use a variety of tactics to maintain a position of power and control by looking out for themselves first, their patient second, and relatives third. The need of the patient and their families is not well understood by nurses, and nurses feel they have inadequate skills to cope with the needs and stresses of visiting relatives. The author suggests that for nurses to provide family focused care in ICU they must develop a therapeutic relationship with all concerned. ICU nursing culture affects nurses ability to focus on caring for their patients and their families. Nurses in ICU appear to need to maintain power and control over their environment but further research is needed to identify the current situation in New Zealand ICUs.
