Nursing intervention studies on patients and family members: a systematic literature review.

The development of evidence-based practice is a major current challenge in the fields of nursing practice and nursing research. A concerted effort is needed to develop and test interventions and to assess their impacts. The illness of one family member inevitably affects other family members and the whole family. Nursing interventions should be so designed that they support and enhance the life situation of both patients and their families. The aim of this study is to undertake a systematic review of nursing intervention studies on patients and family members published in international databases in 2001-2006. The main focus was on the targets, methods and impacts of interventions. The articles for the review were searched from Medline and Cinahl (n = 31) and analysed by content analysis and the RE-AIM evaluation model. The results showed that the interventions were targeted at patients with chronic diseases and individual family members. In addition to support components, the interventions included elements of teaching, counselling and education. The preliminary evidence indicated that the interventions were effective in relieving the burden of care and depressive symptoms of family members of Alzheimer, cancer, stroke and schizophrenia patients as well as in promoting their quality of life and coping. Nursing interventions are still in the development and testing phase. The challenge for the future is to broaden the scope and application of interventions in different nursing environments. Assessments of the efficacy of interventions should also consider their adaptation, implementation and maintenance in practical nursing.
