Background
Competency was first proposed by McLeland, which is defined as a personal trait or a group of habits, leading to more effective or better work performance. Competency is composed primarily of five components: knowledge, skills, self-concept and values, motives, and traits [
1]. American psychologists define competency as the personal characteristics that distinguish superior performers from mediocre performers in a particular environment. It can be knowledge, skill, social role, self-image, trait, motive, etc. [
2]. The Association of Operating Room Nurses (AORN) defines the competency of an operating room (OR) nurse as the knowledge, skills, and abilities required to perform the professional functions of a registered nurse (RN) in the OR [
3]. In China, the definition of OR nurse competency is similar to the above [
4].
In recent years, with the frequent occurrence of public health emergencies, conflicts and natural disasters worldwide, various forms of medical rescue teams are playing an increasingly prominent role. The mobile surgical team is a special team. In the turbulent and severe disaster rescue environment, mobile surgical teams can quickly rescue the wounded and perform simple operations (advanced life support, damage control surgery, damage control resuscitation), which can shorten the rescue time, reduce mortality and disability [
5,
6]. Mobile surgical teams can be deployed independently or as part of a mobile medical team or field hospital. They can provide advanced care with sufficient flexibility and versatility, and they are more convenient and suitable for surgery than field hospitals [
7]. So more and more countries and hospitals establish mobile surgery teams, including International Committee Of Red Cross (ICRC) mobile surgical teams [
8], U.S. Navy Fleet Surgical Team (FST) [
9], U.S. Army Forward Surgical Teams (FSTs) [
10], Army Forward Resuscitative Surgical Teams (FRST) [
11], French Forward Surgical Teams (FSTs), French Surgical Life-saving Module (SLM) [
12], Emergency medical rescue surgical team, China Naval forward surgical team (NFST) [
13].
OR nurse in the mobile surgical team plays a unique role. In China, the mobile surgical team is mainly composed of OR nurses, surgeons, and anesthesiologists [
14]. OR nurses in the surgical team comprise two roles: scrub (or instrument) nurse and circulating (or floor) nurse. The scrub (or instrument) nurse assists the surgeon, administrates the equipment, and drapes the patient. The circulating (or floor) nurse serves the surgical team, positions and disinfects the patient, manages activities outside the sterile field, supervises nursing care during the procedure and acts as the patient’s advocate [
15]. In China, an OR nurse needs to have the competencies of scrub nurse and circulation nurse to be able to perform either role at any time.
The competency of OR nurses is one of the most crucial indicators of patient safety and professional practice standards [
16,
17]. They are essential in the delivery of nursing care to meet the varying needs of injured patients, surgeons, anesthesiologists, and the demands of changing environments and circumstances. In order to maintain and improve a variety of competencies, they participate in surgery work in peacetime just like OR nurses in ordinary hospitals. When deployed, their work sites include battlefields, surgical tents, surgical vehicles, surgical cabins, aeroplanes, ships, or field hospitals [
18]. They need to care for patients with unusual injuries, including multiple injuries, puncture wounds, spinal cord injuries, traumatic amputations, crush injuries, head injuries, burns, infectious diseases, etc. [
19‐
21]. Different working environments, regions, service objects, etc., lead to the unique characteristics of the work. Therefore, OR nurses in mobile surgical teams have unique professional skills and comprehensive abilities that differ from OR nurses in ordinary hospitals.
Competency models have been used in job analysis, performance management, and human resources training and development [
22]. The American academic Boyatzis’ Onion Model, which has multiple interconnected layers and is an enriched competency model [
23]. The outer layer of the Onion Model contains knowledge and skills that can be easily seen and cultivated. The middle layer includes self-concepts and values. The core of the Onion Model encompasses traits and motivations that are difficult to assess, making training in this area also difficult [
2]. Boyatzis’ Onion Model can offer a thorough viewpoint on exploring competencies and competency-based nursing education [
23].
To our knowledge, many studies have reported on the competencies of OR nurses in hospitals. Few studies have explored the competencies of OR nurses in mobile surgical teams. The Onion Model can better explain the competencies of the OR nurses in the mobile surgical team at different levels. Qualitative research approaches can uncover deeper meanings of human experiences and behaviors [
24]. This research method can help us to deeply and extensively explore the competency of OR nurses in mobile surgical teams. In order to gain a better understanding of OR nurses’ competencies, we conducted a qualitative study on the theoretical basis of the Onion Model, which can provide enriched theoretical guidance for competency-based nursing education and competency building.
Discussion
The competencies of OR nurses are conceived as the relationship between technical and non-technical skills [
17,
29]. In our study, technical skills consisted of knowledge and skills, and non-technical skills included professional ability, professional quality, and personal traits. Additionally, the Onion Model’s division of various elements into four layers gives this study a solid theoretical foundation, promotes a clear understanding of competency, and aids in competency-based nursing education and training.
The outermost layer of the onion competency model is technical skills, that is, knowledge and skills that can be easily seen and cultivated. As specialist nurses, the knowledge and skills of the OR nurses are the basis and necessary conditions for all work. The technical areas include operating room-specific nursing knowledge and skills [
30]. In Sweden, specialist OR nurses are responsible for surgical tools, instruments, equipment, aseptic techniques, infection and complication prevention, and biological specimen handling [
16,
31]. Surgical team members are considered accountable for adhering to asepsis guidelines and patient safety concerns in the OR [
32]. In the OR, controlling asepsis and hygiene is crucial for preventing postoperative wound infections [
33]. Wars, disasters, terrors, conflicts and other traumatic life events are unpredictable and often sudden events that cause great damage, destruction and human suffering. Psychological effects can be harmful and far-reaching [
34]. Psychological nursing knowledge is important and should not be ignored. Shin and Kim found that OR nurses had the highest educational demand for knowledge and skills to improve competency [
35].
For the OR nurses of the mobile surgery team, this study found that they also need to acquire unique knowledge and skills, including triage knowledge, self and mutual medical aid, and outdoor survival skills, which are necessary for OR nurses to master when they go out of the fixed hospital and perform rescue missions in the field. Triage is a crucial nursing skill for managing emergencies [
36]. The purpose of triage is to identify the severity of the injury and reduce the negative consequences through rapid evaluation. Triage decisions are often made quickly, independently, and under time constraints, so they can have a serious impact on patient outcomes and flow [
37]. Triage knowledge and professional abilities play important part in nurses’ decision-making. The first aid timeliness rule reveals that self-help and mutual aid have the highest first aid timeliness value (the highest success rate). Nurses should not only rescue the wounded, but also be able to save themselves if they are in danger. Nurses in large hospitals have less exposure to the wild, so they are less able to cope with nature and survive in harsh environments [
38]. Mobile surgical team nurses need outdoor survival skills so that they can better cope with severe situations where disaster, terror, conflict and even war occur frequently. These unique knowledge and skills enrich the competency content of OR nurses, and are also the focus and challenge of the future training and education of mobile surgical team nurses.
The mobile surgical team in China is mainly composed of surgeons, anaesthetists, and OR nurses, to provide the best care for the wounded and safe surgical care. OR nurses being the largest professional group represented play a variety of roles when working with professionals on the surgical team. They collaborate with surgeons, anesthesiologists and nurses to promote surgical performance and increase the likelihood of good patient outcomes [
39]. When an emergency occurs, a mobile surgical team is selected temporarily, and the team members are often not familiar with each other. Patient safety may be compromised if there is a lack of continuity and stability in team familiarity, which could lower individual and team performance [
40]. For such a team, communication skills, teamwork skills, and coordination abilities are crucial. Studies have found that communication in the OR has a considerable effect on the performance of the surgical team, and thus has a significant impact on patient safety and treatment outcomes [
41]. Communication skills, as a non-technical skill, complement technical skills to handle emergency deployment tasks efficiently and safely. Furthermore, effective communication can help wounded feel less anxious. Teamwork skills in the surgical team are associated with a reduction in adverse events, as well as improved patient outcomes, including reductions in mortality and complications [
42]. Good cooperation (i.e., team-based attitudes), communication (i.e., the exchange of information between members), and coordination (i.e., teamwork behaviours) among surgical team members create a tranquil workplace for the workforce, reducing medical errors and complications for patients [
39,
43].
The OR is a complex, dynamic, and stressful work environment [
44], especially when dealing with emergency rescue deployments. In this setting, life-threatening circumstances and occurrences needing quick decisions frequently occur. Surgical team members need more than specialized knowledge and technical skills. To achieve safe, effective patient outcomes, OR teams must comprehend the complexity of clinical circumstances, coordinate patient care utilizing modern tools and procedural approaches while reacting to frequently quick patient conditions changes [
44]. von Vogelsang et al. found that OR nurses need to be able to synthesize knowledge and analyze, evaluate, and handle complex situations [
16]. Moreover, they should have the competencies common to other specialized nurses, such as disease observation ability, emergency response capability, and management ability, which are consistent with the research results of Wang et al. [
14]. To maintain wounded safety, infection prevention, psychological safety, environmental safety, and team safety, the OR nurse is responsible for the WHO checklist’s needle, sponge, and tool count as well as the management of specimens [
45‐
47]. OR nurses must know where everything is and monitor everything in the OR. Additionally, the OR nurse is in charge of directing traffic inside the OR [
48]. A scarcity of resources might occur during deployment for an OR nurse, thus managing supplies and adapting are crucial skills [
49]. The ability of an OR nurse also includes dispute resolution, resource organization, and prioritization in light of the constantly shifting and unpredictable needs of the surgical setting [
29]. The professional abilities excavated in this study mainly focus on the abilities required for team work, and provide a basis for the cultivation and formation of professional abilities of OR nurses in the future.
Quality is an essential quality of physical and mental development, which is relatively stable once formed. Professional quality is a comprehensive reflection of labourers’ understanding and adaptability to social occupation. It is the third layer of the onion competency model of OR nurses, which is not easy to find and cultivate. In our study, the professional quality of OR nurses includes physical abilities, psychological adaptation, sense of discipline, sense of responsibility, team spirit, patient-friendly consciousness, and aseptic consciousness. The OR has a large workload, high work intensity, high work pressure [
44,
50], irregular working hours, changing and fast-paced environment, unexpected situations, and uncertain demands [
29]. In addition, the mobile surgical team often face urgent rescue missions, which puts forward higher requirements on physical ability and psychological adaptation. Physical and mental health are fundamental conditions for working. And the professional attitude or quality of an OR nurse requires concern for others, service consciousness, a sense of responsibility, and team spirit [
51,
52]. During surgery, OR nurses ensure that the wounded receive perioperative care that is person-centred [
53]. Wang et al. study shows that OR nurses need to possess the essential competency characteristics of patient-friendly consciousness [
14]. Janatolmakan and Khatony found that nurses who lack teamwork spirit can lead missed nursing care [
54]. In our study, a sense of discipline is a particular competency. During deployment, a sense of discipline is essential for a team to ensure safety and completion of the mission. Although this part of the competencies is not easy to develop, they can help managers develop long-term training programs and appropriate educational methods to develop OR nurses’ competencies. At the same time, they provide a basis for managers to select suitable OR nurses for mobile surgical teams.
Personal traits are the innermost layer of the onion competency model of the OR nurses. They are the inner, difficult to measure, difficult to find and change aspects of people. Previous studies found that OR nurses have personal characteristics of agility, attention to detail, stress resistance, flexibility, endurance, persistence, and inclusiveness [
51,
52,
55,
56], consistent with our findings. With an operations tempo, mobile surgical teams must be small and agile [
57]. To rapidly locate any surgical supplies or medications, OR nurses must be agile and quick-thinking, especially in challenging or unexpected situations. This calls on them to exercise caution, to pay attention to both the big picture and the minute particulars, and to always be aware of the needs of the patient, the equipment, and the surgical team. While listening to the surgeon, the OR nurses can help with the process while keeping an eye on the patient, the equipment gauges, and other signs that everything is proceeding according to plan. Most surgical teams are set up ad hoc and may consist of different team members for each deployment. Team members may be unfamiliar with each other’s skills, abilities, work habits and styles. Lack of understanding of each further increases the likelihood of miscommunication and disruption during surgery [
40]. These conditions challenge the adaptive capacity, flexibility, and inclusiveness of team members. Higher and more modern standards are being set for nursing talent in quantity, quality, and structure as OR nursing continues to advance. Exploring personal traits will help managers select suitable and competent OR nurses for the mobile surgical team.
The study has its limitations. First, the deductive approach to data analysis and the usage of the Onion Model as a theoretical framework for interview outlines may introduce some biases. Second, the results are time- and context-specific, so they may not be applied to all OR nurses. Third, due to the limited experience of interviewees in different deployment tasks, the results will be biased. The last, interviews were conducted in Chinese, then analyzed and translated into English. Although the authors worked hard to ensure proper translation with the help of professional English editors, there was still a small risk that the process could affect the results of the study.
