Systematic reviews: gatekeepers of nursing knowledge

Accompanying critically ill relatives in emergency departments

BACKGROUND

Family members are a crucial part of the holistic approach to care in emergency departments. In particular, they are a group who are vulnerable, yet have been overlooked when considering care options.

AIM

The primary aim of this systematic review was to appraise research relevant to identifying and meeting the needs of family members who accompany a critically ill person into the Emergency Department (ED). The information was intended to inform future research into the care of these people.

METHOD

A quality assessment strategy was specifically developed to evaluate the various research designs used. The outcomes of the highest quality studies were used to develop evidence-based clinical practice guidelines to inform clinicians caring for family members who accompany a critically ill person into the ED.

RESULTS

Recommendations for family care drawn from this review provide the foundation for more rigorous methodologies in future research into this topic. Key findings concern family needs for communication, proximity, support, comfort, assurance and to locate meaning in the event.

CONCLUSION

The review has revealed current knowledge about the care of family members who accompany a critically ill person into the ED that provides guidelines for practice. Despite significant limitations, the knowledge can lead to recommendation to guide and inform future intervention research.

Evidence-based practice in Hong Kong: issues and implications in its establishment

Evidence-based practice has been widely discussed in the literature, but it is not common or well adopted in nursing practice, both in Hong Kong and other countries. This article aims to examine the relationships between three important elements of evidence-based practice: systematic reviews, clinical guidelines and protocols. Current issues associated with evidence-based practice in Hong Kong are explored. Specific suggestions are given to researchers, practitioners, managers and academics so that the current situation can be advanced.

Developing best practice in critical care nursing: knowledge, evidence and practice

Because the current drive towards evidence-based critical care nursing practice is based firmly within the positivist paradigm, experimentally derived research tends to be regarded as 'high level' evidence, whereas other forms of evidence, for example qualitative research or personal knowing, carry less weight. This poses something of a problem for nursing, as the type of knowledge nurses use most in their practice is often at the so-called 'soft' end of science. Thus, the 'Catch 22' situation is that the evidence base for nursing practice is considered to be weak. Furthermore, it is argued in this paper that there are several forms of nursing knowledge, which critical care nurses employ, that are difficult to articulate. The way forward requires a pragmatic approach to evidence, in which all forms of knowledge are considered equal in abstract but are assigned value according to the context of a particular situation. It is proposed that this can be achieved by adopting an approach to nursing in which practice development is the driving force for change.
