The quantitative portion deals with a comparison between the knowledge and practice of the nurses from the acute care wards. Risks and complications like trauma, hypoxemia, cardiac arrest, and death have been associated with the procedure and hence the necessity to know whether the procedure is competently performed by nurses using a method of triangulation could be surmised as contributing to the problem statement. The nurses’ competence decides whether the aspect of proper tracheal suctioning ensures patient safety. The significance of the problem has thus been discussed. The authors are fairly clear in their study and exhibit the confidence to achieve their objective. The significance of the competence of the nurses in performing the procedure with the focus on patient safety is rightly expressed. Key research questions have not been identified but they could be the following:
The variables are knowledge and practice. The study does not have the potential to completely solve the issue of inexperienced nurses in the service. However, it has shown the depth of the issue and that the general population is being delivered health care by nurses who do not follow the current research recommendations. The literature review is very short and speaks mainly of only a few articles between the periods 1968 to 2001. The information in it is written in a sequence of potential complications. The review implies that not much research has been done on the subject of nursing practices of tracheal suctioning. The authors speak of gaps: tracheal suctioning has little been researched even though the significance of this procedure has potential hazards. The closest that research has reached this study is the study on endotracheal suctioning which showed a poor knowledge and practice level with no relationship between the two among intensive care nurses (Day et al, 2001). Celik and Elbas (2000) indicated that endotracheal suctioning was not done according to current recommended research practices.
