Re-evaluating triage in the new millennium: A comprehensive look at the need for standardization and quality☆,☆☆

Emergency and mental health nurses are, in many countries, the designated professionals to conduct acute mental health triage. This review aimed to identify competencies these nurses need in major acute health care services such as emergency and accident departments and mental health crisis services for triage for psychiatric patients in crisis.

For familiarization and construction of an initial thematic framework, we have searched the databases MEDLINE, CINAHL, Academic Search Premier, and PsycINFO since 1975. For indexing and sorting, the web-based application Rayyan was used to identify relevant studies. ATLAS.ti 22 was used for data extraction, reviewing, summary, and display using labels relevant for our research questions: knowledge, skills, and attitude. For appraisal of the included studies, the Mixed Methods Appraisal Tool and the Scale of the Assessment for Narrative Reviews were used.

Thirty one studies were included and were overall rated as adequate, mostly published since 2000. Competencies needed by nurses in AMHT contain a high level of specialist knowledge (risk assessment, de-escalation, triage tools, psychopathology, law/regulations, care pathways), skills (clinical skills, communication, collaboration, coordinating care), and attitude (nonjudgmental, confidence).

Emergency and mental health nurses require a significant amount of competencies beyond basic nursing education in acute mental health triage. Most described competencies pertain both to knowledge and skills. Less is known about attitude. To integrate the several competencies knowledge, skills, and attitude, clinical reasoning is needed to organize chaos in unpredictable and complex patient situations.

This research was designed to examine if there is a difference in nurse attitudes and experience for those who assign Emergency Severity Index (ESI) scores accurately and those who do not assign ESI scores accurately. Studies that have used ESI scoring discussed the role of experience, but have not specifically addressed how the amount of experience and attitude towards patients in triage affect the triage nurse's decision-making capabilities.

A descriptive, exploratory study design was used. Data from 64 nurses and 1,644 triage events at 3 emergency departments was collected. Participants completed demographic data, attitude (Caring Nurse Patient Interaction, CNPI-23) survey, and triage data collection tools during the continuous 8-hour triage shift. Clinical nurse expert raters retrospectively reviewed the charts and assigned an ESI score to be compared with the nurse. Descriptive statistics were used to describe the nurse and Pearson's correlation was used to examine the relationship between experience and attitude.

In this study of 64 nurse participants, the ESI score assigned by nurse participants did not differ significantly based on years of experience or CNPI mean score. The Kappa statistic ranged from a high of 0.63 in the nurse participant with 1.00 to 1.99 years of experience to a low of 0.51 in the nurse participant with 15 to 19 years of experience. The nurse participants with an overall mean CNPI-23 score of 106 to 115 achieved the highest agreement compared with a single participant with a CNPI-23 overall mean score of less than 77 who had a Kappa agreement of 0.50. The nurse participants with a CNPI-23 overall mean score between 81 and 92 demonstrated agreement of 0.54 to 0.60.

Based on the high level of liability the triage area presents, special consideration needs to be made when deciding which nurse should be assigned to that area. The evidence produced from this study should provide some reassurance to ED managers and nurses alike that nurses with minimal ED experience and a working understanding of the ESI 5-level triage algorithm possess the knowledge and the capacity to safely and appropriately triage patients in the emergency department.
