Abstract: This thesis explores triage code as a predictor of direct nursing care time, thus its potential usefulness in a model for calculating and allocating nurse requirements in emergency departments. A framework for nursing work is proposed. This framework is based on the works of O'Brien-Pallas, Irvine, Peereboom, and Murray (1997) and Houser (2003). It suggests that the structures of environmental complexity, nursing characteristics, patient nursing complexity, and patient medical condition and severity, impact on the processes of direct and indirect nursing care to affect patient outcomes. A prospective, non-experimental study was undertaken to examine the relationship between direct nursing care time and triage code. Six potential confounding variables were selected for this study: length of stay, age, ethnicity, sex, complaint type, and discharge category. Data were collected for 261 visits over a three day period in one New Zealand emergency department. Patient visits averaged 200 minutes. The mean direct nursing care time per visit was 49 minutes. On average, patients with more urgent triage codes, longer length of stay, or who were not discharged, received more direct nursing care. The model developed predicted 49% of variation in direct nursing care time (p < .05) related to triage code (16%), length of stay (31%) and disposition category (2%). The author suggests that further exploration of the proposed framework has potential to develop a model allowing managers to identify nurse staffing required for optimal nursing care in emergency departments.

Abstract: With the intention of decreasing emergency department demand, there has been a focus on determining those patients who do not require the services of the emergency department so they can be redirected away to an alternative health care provider or facility. Co-locating an after-hours primary health care facility near to the emergency department is a model under consideration in some district health boards. This model suggests that a substantial proportion of the patients currently managed in the emergency department can be assessed and managed in a general practice setting. It is envisaged that by redirecting the lower acuity patients away from the emergency department, overcrowding will be relieved. This is despite evidence demonstrating that low acuity patients are not the cause of emergency department overcrowding. Moreover, being treated at the emergency department is the only safety net for many people in the community who cannot afford alternative care. This research report discusses the literature regarding the practice of referring or redirecting patients away from the emergency department and the issues associated with this model. In doing this, it looks at the Australasian Triage Scale, the system used to ensure patients are seen in order of clinical urgency, because it has been suggested that this system could be used as a tool to refer patients away from the emergency department. The author concludes that even though some people could be seen by another health care provider, the triage system is not an appropriate tool for achieving this. While it is tempting to believe that patients in the lower triage categories are prime candidates for being referred away, there is evidence from hospital statistics that patients in these categories have a high number of hospital admissions and in-hospital death rates. Additionally, to complicate matters, there is no universal definition of what constitutes an 'appropriate' emergemcy department presentation and no consensus of opinion amongst health professionals in deciding patients' 'appropriateness'. For these reasons it is unethical to expect nurses who administer the triage system to use it for the purpose of referring people away from the emergency department.
