  Abstract 


Background: Accurate decision-making in triage requires continuous education, so triage nurses should receive annual refresher courses. Identifying the most effective method can make the provision of practical education to triage staff in hospitals possible. This review was conducted with the aim to determine the effectiveness of triage education methods in Iran. Materials and Methods: In this systematic review on educational intervention studies, international and Iranian medical sciences databases were searched using a defined search strategy compatible with each database. PubMed, Scopus, Web of Science, Google Scholar, SID, Islamic Science Center (ISC), and IranDoc databases were searched for literature published from January 2010 to January 2020. The MeSH terms of “health care staff,” “triage,” “education,” and “Iran” in English and Persian were combined to develop a search strategy. Initially, 768 article titles were retrieved. Finally, 16 articles were selected for the review. Results: All conducted studies were quasi-experimental. Half of the studies had used a face-to-face approach for education (workshop, lecture, and simulation), and four studies had used lectures and pamphlets. All studies (except 1) reported that their educational intervention significantly improved nursing knowledge on triage. Conclusions: Almost all studies had reported the effectiveness of an educational intervention in improving nurses' triage knowledge. However, it seems that the non-face-to-face method is superior to the face-to-face method because of its learner-centeredness and cost-effectiveness. Moreover, providing educational content using a blended learning approach (simulation and games) can enhance the effectiveness of triage education.

  Introduction Top


Triage refers to the process of patients' prioritization for receiving health care in emergency departments without loss of time.[1] Lack of knowledge regarding triage is the main cause of the misclassification of patients.[2],[3],[4],[5] Moreover, enough knowledge is an important part of the triage process. Thus, the Iranian Emergency Medical Service Organization guideline emphasizes annual occupational training regarding triage, especially for nursing staff.[1],[6] As a result, in the last couple of years, numerous investigations have been conducted to assess the efficacy of different educational methods in improving the knowledge and practice of triage nurses in Iran.[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17] One study showed that education through lectures can enhance nurses' triage knowledge.[10] Furthermore, Rostampour et al. showed that combining several educational methods (such as lecture, hands-on training, and pamphlets) can effectively increase nurses' triage knowledge.[18]

Despite the implementation of these interventions and annual on-the-job training in all Iranian hospitals, the results of surveys have indicated that nurses have inadequate knowledge and the accuracy of their decision is low. Haghigh et al. reported that nurses of emergency departments in Ahvaz (southwest of Iran) had poor knowledge about triage.[5] Several studies have shown that the accuracy of triage decisions made by nurses was low.[4],[19] In addition, inadequate knowledge and poor practice regarding triage have been reported among Emergency Medical Technicians (EMTs) in Khuzestan Province, Iran.[20] Familiarity with triage systems leads to consistent decisions among triage nurses.[21],[22] Although medical authorities stress the importance of knowledge of triage nurses, they do not agree on the best educational method in respect to its effectiveness on the knowledge of nurses about triage.[2],[3],[4],[5] Identifying the most effective method can enable the provision of practical education to triage staff in hospitals. This review was conducted with the aim to determine the effectiveness of triage education methods in Iran.


  Materials and Methods Top


This systematic review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Scopus, Web of Science, Google Scholar, Scientific Information Database (SID), Islamic World Science Citation Center (ISC), and IranDoc databases were searched for literature published from January 2010 to January 2020. The number of articles in each database is shown in the PRISMA flowchart [Figure 1].

The study inclusion criteria included articles on triage training in Iran from January 2010 to January 2020, articles with qualitative and quantitative approaches, articles with full text access, written in English or Persian. The exclusion criteria included the articles presented at conferences and seminars, letters to editor, case reports, and book reviews, lack of access to the full text of articles, articles written in a language other than English or Persian. First, the titles of searched articles were imported into Endnote software. The duplicate titles were then removed. Titles and abstracts were screened by the first and second authors independently, and any disagreements were resolved by the third author. Articles with unclear abstracts were assessed according to their full text. The process of study selection is presented in the PRISMA flowchart [Figure 1].

Studies eligible for inclusion in the study included studies that performed an educational intervention regarding triage in hospital and pre-hospital settings in Iran and studies that taught triage in normal circumstances, mass-casualty incidents (MCIs), or disasters. Based on the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI), medium-quality and high-quality studies were included in the review. The JBI is an evidence-based healthcare institute, which provides professionals in nursing, midwifery, medicine, and allied health access to resources; it collaborates with over 80 centers in over 90 countries. This tool has a checklist containing nine questions. The reviewer analyzes different parts of the article using this checklist. Each question has four responses (Yes, No, Unclear, or Not Applicable). In the end, the reviewer selects one of the options of “include,” “exclude,” or “seek further info.” If the article is excluded, the reason should be mentioned.[23] Low quality studies and those the full text of which was unavailable were excluded from the review.

Using the JBI-MAStARI, the first and third authors independently assessed the quality of the articles. Any disagreements were resolved through discussion. A data extract form was developed based on the study goal. The data extracted from each article consisted of “the first author,” “year of publication,” “sample size,” “participants,” “study design,” teaching method,” “conclusion,” and “recommendations.” After data extraction, the papers were categorized into Face-to-Face (FTF), no-FTF, blended (FTF and no-FTF), and comparative (FTF with no-FTF) methods and analyzed.

Ethical considerations

The institutional review board in the School of Public Health, Tehran University of Medical Sciences, approved this study (IR.TUMS.SPH.REC.1395.508).


  Results Top


Of the 767 titles retrieved from the databases, 293 duplicates were removed. In addition, 457 titles were deleted because they were irrelevant or not related to the implementation of an educational intervention. Moreover, one article was removed because of lack of access to its full text despite emailing its corresponding author and requesting its full text.[24] Then, the remaining 17 full-text articles were reviewed for eligibility. Of these, two articles were removed because of their poor quality,[25],[26] and the remaining 15 articles were entered into the study. Next, one article was included as a result of hand-searching the reference list of the selected articles.[27] Finally, 16 articles (10 in English and 6 in Persian) were analyzed [Figure 1].

As seen in [Table 2], all studies had a quasi-experimental design. Moreover, seven articles had a single-group intervention, four articles had both intervention and control groups, three researches compared the FTF method and no-FTF method, and one study compared 2 FTF methods.{Table 1}

In all of the included studies, except for the study by Azhough et al.,[11] the intervention had a significant effect on the knowledge of participants in educational courses. In a review of 16 selected papers, a posttest was performed in 14 (87%) studies within 1 month after the intervention.[7],[8],[10],[11],[12],[13],[14],[15],[16],[27],[28],[29],[30],[31] In one study, researchers performed a posttest 6 weeks[9] and in another 3 months[17] after the intervention. In the reviewed papers, triage education was presented through lecture, multimedia software, simulation, workshop, booklet, video podcasting scenario, and role-playing separately or in combination.[7],[8],[10],[11],[12],[13],[14],[15],[16],[27],[28],[29],[30],[31]

The participants in 11 studies (69%) were emergency nurses,[7],[8],[11],[12],[13],[14],[16],[17],[18],[26],[27] in two studies (27,30) nursing students, in two studies (10,29) EMTs, and in one study emergency nurses and EMTs.[9] The educational content of seven studies (44%),[8],[9],[12],[15],[16],[27],[30] six studies,[7],[10],[13],[14],[17],[28], two studies,[18],[29] and pne study[11] was, respectively, related to hospital triage algorithm under normal situations [Emergency Severity Index (ESI)], disaster and mass casualty triage (START algorithm), pre-hospital disaster, and mass casualty triage, and both ESI and START algorithms.


  Discussion Top


Based on the results of the reviewed studies, there are different methods of triage training, each with its special benefits. The strong point of this research is the study of all Iranian educational interventions in the field of triage education and comparison of their effectiveness. Moreover, because all studies were quasi-experimental, there is a possibility of misstatement of study results. The present study was conducted with the aim to compare these methods in order to find the most effective methods.

FTF and no-FTF methods

In all reviewed studies, except for the study by Azhough et al.[11] significant changes in participants' knowledge were reported after training courses.[28],[29],[30] Rouleau et al.[31] concluded that if more attention was paid to e-learning as a form of no-FTF education in nursing, this method could play an important role in enhancing the quality of nursing care. Moradi and Dideban.[32] Ghezeljeh et al.,[33] and Rostamnia et al.[34] also reported that mobile learning as a kind of no-FTF education method has positive and useful features such as its accessibility and learner-centeredness. FTF and no-FTF have nearly similar effects on enhancing nurses' knowledge regarding evidence-based practice. However, no-FTF is a preferred training method for nurses as it is more cost-effective.[35] Researchers reported that an effective educational method must be student-centered and based on class discussion.[36],[37] It seems that these features are in accordance with the no-FTF educational method. Thus, applying these methods in triage training could yield longer and more cost-effective results for learners and hospital managers.

Blended and non-blended approaches

In eight studies, lecture was used as the only educational method the effect of which was significant,[7],[8],[9],[10],[11],[12],[13],[14] except in one study.[11] Even though pedagogical educational method, lecturing, has emphasized the role of learners in education,[37] this method neglects the role of learners in their education.[38] Although using lecture alone for the training of triage might have a significant effect on enhancing nurses' knowledge, this effect only remains for a short time. Therefore, the use of a combination of educational methods allowing for the participation of learners in training courses is recommended. In four studies, blended techniques, including lecture, scenario, and educational pamphlets, had been used and the effectiveness of this approach was reported.[8],[15],[16],[17] This can be because of the benefit of using several different teaching methods. Other benefits of a blended learning approach were the opportunity to review e-content for the learner, reduction of the feeling of isolation, an increase of pervasive interest in the subject under discussion,[39] mental imagery, self-motivation, and maintaining grades.[40]

Using lectures along with other methods such as educational software and group discussion is more effective compared to using lectures alone because learners are more actively engaged in the learning process.[39] A review study reported that a blended approach had a consistently positive effect compared to non-blended learning (pure e-learning or pure FTF method).[40] In another review study, it was reported that, in nursing education, the blended learning approach enhances learners' knowledge and skills. This method enables profound and active learning and is preferred to traditional and FTF methods.[41] As a result, the blended learning method may be suitable in the field of triage for scholars and teachers.

Consolidation of memory

In all of the included studies, except for one,[11] the intervention had a significant effect on the knowledge of participants in educational courses. Moreover, the results of surveys indicated that nurses have inadequate knowledge and the accuracy of their decision is low.[4],[5],[19],[20] There are various reasons for this contradiction. One of these reasons may be the forgetting of information due to the long interval between training.

Memories are stored in the brain through variation in the basic sensitivity of synaptic transmission between neurons as a result of previous neural activity. There are three different types of memory, which include short-term memory that lasts seconds or at most minutes, intermediate-term memory that lasts days to weeks, and long-term memory that can be recalled up to years or even a lifetime later. Short-term memory can be converted into long-term memory through being recalled weeks or years later.[42] The limitations of this study included restriction on full access to some databases such as Ovid, and lack of access to the full text of some articles.


  Conclusion Top


All education methods, including FTF, no-FTF, non-blended, and blended methods, are effective in triage learning. The results indicate that no-FTF and blended methods have many interesting features versus FTF and non-blended methods in triage training. In all studies, researchers performed posttests up to three months after the intervention. Therefore, regular training of triage content is necessary. Because of the easy access to devices such as mobile phones, virtual networks can be used for the repetition of content and long-term memory consolidation. However, deciding on the most effective educational method requires further studies and the comparison of different learning methods. In conclusion, it can be stated that triage training can be made more effective and efficient through the utilization of the potential capacity of virtual education platforms available in medical sciences universities, social networks, games, and mobile applications.
