Qualitative investigation of military surgical resuscitation teams: what are the drivers of success of a rapid response team?

OBJECTIVES: This qualitative study explores the characteristics of a specialised military medical rapid response team (MRRT), the surgical resuscitation team (SRT). Despite mixed evidence of efficacy, civilian MRRTs are widely employed, with significant variation in structure and function. Recent increased use of these teams to mitigate patient risk in challenging healthcare scenarios, such as global pandemics, mass casualty events and resource-constrained health systems, mandates a reconceptualisation of how civilian MRRTs are created, trained and used. Here, we study the core functions and foundational underpinnings of SRTs and discuss how civilian MRRTs might learn from their military counterparts. DESIGN: Semistructured interview-based study using Descriptive Qualitative Research methodology and Thematic Analysis. SETTING: Remote audio interviews conducted via Zoom. PARTICIPANTS: Participants included 15 members of the United States Special Operations Command SRTs, representing all medical specialties of the SRT as well as operational planners. RESULTS: Adaptability was identified as a core function of SRTs and informed by four foundational underpinnings: mission variability, shared values and principles, interpersonal and organisational trust and highly effective teaming. Our findings provide three important insights for civilian MRRTs: (1) team member roles should not be defined by silos of professional specialisation, (2) trust is a key factor in the teaming process and (3) team principles and values result in and are reinforced by organisational trust. CONCLUSION: This study offers the first in-depth investigation of a unique military MRRT. Important insights that may offer benefit to civilian MRRT practices include enabling the breakdown of traditional division of labour, allowing for and promoting deep interpersonal and professional familiarity, and facilitating a cycle of positive reinforcement between teams and organisations. Future investigation of small team limitations, comparability to civilian MRRTs, and the team relationship to the larger organisation are needed to better understand how these teams function in a healthcare system and translate to civilian practice.

How do residents respond to uncertainty with peers and supervisors in multidisciplinary teams? Insights from simulations with epistemic fidelity.

BACKGROUND: Residents struggle to express clinical uncertainty, often exhibiting negative cognitive, behavioral, and emotional responses to uncertainty when engaging with patients or supervisors. However, the Integrative Model of Uncertainty Tolerance posits that individuals may have positive or negative responses to perceived uncertainty. Situational characteristics, such as interactions with other health professionals, can impact whether the response is positive or negative. The team context in which residents interact with resident peers and supervisors could represent varying situational characteristics that enable a spectrum of responses to uncertainty. Understanding the situational characteristics of multidisciplinary teams that allow residents to display positive responses to perceived uncertainty could inform strategies to foster positive responses to uncertainty in other contexts. We explored resident responses to perceived uncertainty in a simulated multidisciplinary team context. METHODS: A simulation-primed qualitative inquiry approach was used. Fourteen residents from Cardiology and Obstetrics and Gynecology participated in simulation scenarios involving pregnant patients with heart disease. We incorporated epistemic fidelity through the deliberate inclusion of ambiguity and complexity to prompt uncertainty. Audio recordings of debriefing sessions were analyzed using directed content analysis. RESULTS: Residents recognized that uncertainty is unavoidable, and positive responses to uncertainty are crucial to team dynamics and patient safety. While residents had positive responses to expressing uncertainty to peers, they had predominantly negative responses to expressing uncertainty to supervisors. Predominant negative response to supervisors related to judgement from supervisors, and impacts on perceived trustworthiness or independence. Although residents recognized expressing uncertainty to a supervisor could identify opportunities for learning and resolve their uncertainty, the negative responses overshadowed the positive responses. Residents highly valued instances in which supervisors were forthcoming about their own uncertainty. CONCLUSIONS: Through participation in simulations with epistemic fidelity, residents reflected on how they perceive and respond to uncertainty in multidisciplinary teams. Our findings emphasize the role of situational characteristics, particularly peers and supervisors, in moderating responses to perceived uncertainty. The productive discussions around responses to uncertainty in debriefing sessions suggest further studies of multidisciplinary simulations could enhance our understanding of how uncertainty is expressed, and potentially be used as an instructional intervention to promote positive responses to uncertainty.

Team Stress and Its Impact on Interprofessional Teams: A Narrative Review.

Phenomenon: Interprofessional healthcare team (IHT) collaboration can produce powerful clinical benefits for patients; however, these benefits are difficult to harness when IHTs work in stressful contexts. Research about stress in healthcare typically examines stress as an individual psychological phenomenon, but stress is not only a person-centered experience. Team stress also affects the team's performance. Unfortunately, research into team stress is limited and scattered across many disciplines. We cannot prepare future healthcare professionals to work as part of IHTs in high-stress environments (e.g., emergency medicine, disaster response) unless we review how this dispersed literature is relevant to medical education. Approach: The authors conducted a narrative review of the literature on team stress experienced by interprofessional teams. The team searched five databases between 1 Jan 1990 and 16 August 2021 using the search terms: teams AND stress AND performance. Guided by four research questions, the authors reviewed and abstracted data from the 22 relevant manuscripts. Findings: Challenging problems, time pressure, life threats, environmental distractors, and communication issues are the stressors that the literature reports that teams faced. Teams reacted to team stress with engagement/cohesion and communication/coordination. Stressors impact team stress by either hindering or improving team performance. Critical thinking/decision-making, team behaviors, and time for task completion were the areas of performance affected by team stress. High-quality communication, non-technical skills training, and shared mental models were identified as performance safeguards for teams experiencing team stress. Insights: The review findings adjust current models explaining drivers of efficient and effective teams within the context of interprofessional teams. By understanding how team stress impacts teams, we can better prepare healthcare professionals to work in IHTs to meet the demands placed on them by the ever-increasing rate of high-stress medical situations.

Set Up to Fail? Barriers Impeding Resident Communication Training in Neonatal Intensive Care Units.

PURPOSE: Learning to navigate difficult clinical conversations is an essential feature of residency training, yet much of this learning occurs "on the job," often without the formative, multisource feedback trainees need. To generate insight into how on-the-job training influences trainee performance, the perspectives of parents and health care providers (HCPs) who engaged in or observed difficult conversations with Neonatal Intensive Care Unit (NICU) trainees were explored. METHOD: The iterative data generation and analysis process was informed by constructivist grounded theory. Parents (n = 14) and HCPs (n = 10) from 2 Canadian NICUs were invited to participate in semistructured interviews informed by rich pictures-a visual elicitation technique useful for exploring complex phenomena like difficult conversations. Themes were identified using the constant comparative approach. The study was conducted between 2018 and 2021. RESULTS: According to participants, misalignment between parents' and trainees' communication styles, HCPs intervening to protect parents when trainee-led communication went awry, the absence of feedback, and a culture of sole physician responsibility for communication all conspired against trainees trying to develop communication competence in the NICU. Given beliefs that trainees' experiential learning should not trump parents' well-being, some physicians perceived the art of communication was best learned by observing experts. Sometimes, already limited opportunities for trainees to lead conversations were further constricted by perceptions that trainees lacked the interest and motivation to focus on so-called "soft" skills like communication during their training. CONCLUSIONS: Parents and NICU staff described that trainees face multiple barriers against learning to navigate difficult conversations that may set them up to fail. A deeper understanding of the layered challenges trainees face, and the hierarchies and sociocultural norms that interfere with teaching, may be the start of breaking down multiple barriers trainees and their clinician supervisors need to overcome to succeed.

Unintended consequences of technology in competency-based education: a qualitative study of lessons learned in an OtoHNS program.

BACKGROUND: Formative feedback and entrustment ratings on assessments of entrustable professional activities (EPAs) are intended to support learner self-regulation and inform entrustment decisions in competency-based medical education. Technology platforms have been developed to facilitate these goals, but little is known about their effects on these new assessment practices. This study investigates how users interacted with an e-portfolio in an OtoHNS surgery program transitioning to a Canadian approach to competency-based assessment, Competence by Design. METHODS: We employed a sociomaterial perspective on technology and grounded theory methods of iterative data collection and analysis to study this OtoHNS program's use of an e-portfolio for assessment purposes. All residents (n = 14) and competency committee members (n = 7) participated in the study; data included feedback in resident portfolios, observation of use of the e-portfolio in a competency committee meeting, and a focus group with residents to explore how they used the e-portfolio and visualize interfaces that would better meet their needs. RESULTS: Use of the e-portfolio to document, access, and interpret assessment data was problematic for both residents and faculty, but the residents faced more challenges. While faculty were slowed in making entrustment decisions, formative assessments were not actionable for residents. Workarounds to these barriers resulted in a "numbers game" residents played to acquire EPAs. Themes prioritized needs for searchable, contextual, visual, and mobile aspects of technology design to support use of assessment data for resident learning. CONCLUSION: Best practices of technology design begin by understanding user needs. Insights from this study support recommendations for improved technology design centred on learner needs to provide OtoHNS residents a more formative experience of competency-based training.

Building Resilient Healthcare Teams: Insights from Analogy to the Social Biology of Ants, Honey Bees and Other Social Insects.

The resilience of a healthcare system hinges on the adaptability of its teams. Thus far, healthcare teams have relied on well-defined scopes of practice to fulfill their safety mandate. While this feature has proven effective when dealing with stable situations, when it comes to disruptive events, healthcare teams find themselves navigating a fine balance between safety and resilience. Therefore, a better understanding of how the safety vs resilience trade-off varies under different circumstances is necessary if we are to promote and better train for resilience in modern healthcare teams. In this paper, we aim to bring awareness to the sociobiology analogy that healthcare teams might find useful during moments when safety and adaptability have the potential to conflict. Three principles underpin the sociobiology analogy: communication, decentralization, and plasticity. Of particular interest in this paper is plasticity whereby swapping roles or tasks becomes an adaptive, rather than a maladaptive, response teams could embrace when facing disruptive situations. While plasticity has naturally evolved in social insects, infusing plasticity in healthcare teams requires intentional training. Inspired by the sociobiology analogy, such training must value the ability: a) to read each other's cues and miscues, b) to step aside when others had the necessary skills, even if outside their scope, c) to deviate from protocols, and d) to foster cross-training. If the goal is to increase a team's behavioural flexibility and boost their resilience, this training mindset should become second nature.

Professional identity struggle and ideology: A qualitative study of residents' experiences.

INTRODUCTION: To enter a profession is to take on a new identity. Professional identity formation can be difficult, with medical learners struggling to adopt professional norms. The role of ideology in medical socialisation may offer insight into these tensions experienced by medical learners. Ideology is the system of ideas and representations that dominates the minds of individuals or social groups and calls individuals into certain ways of being and acting in the world. In this study, we use the concept of ideology to explore residents' experiences with identity struggle during residency. METHODS: We conducted a qualitative exploration of residents in three specialties at three academic institutions in the United States. Participants engaged in a 1.5-hour session involving a rich picture drawing and one-on-one interview. Interview transcripts were coded and analysed iteratively, with developing themes compared concurrently to newly collected data. We met regularly to develop a theoretical framework to explain findings. RESULTS: We identified three ways that ideology contributed to residents' identity struggle. First was the intensity of work and perceived expectations of perfectionism. Second were tensions between the developing professional identity and pre-existing personal identities. Many residents perceived messages regarding the subjugation of personal identities, including the feeling that being more than physicians was impossible. Third were instances where the imagined professional identity clashed with the reality of medical practice. Many residents described how their ideals misaligned with normative professional ideals, constraining their ability to align their practice and ideals. CONCLUSION: This study uncovers an ideology that shapes residents' developing professional identity-an ideology that creates struggle as it calls them in impossible, competing or even contradictory ways. As we uncover the hidden ideology of medicine, learners, educators and institutions can play a meaningful role in supporting identity development in medical learners through dismantling and rebuilding its damaging elements.

What do you mean, 'negotiating?': Patient, physician, and healthcare professional experiences of navigating hierarchy in networks of interprofessional care.

Interprofessional collaborative practice is a phenomenon that can be fraught with power dynamics between professions, within professions, and between professionals and patients. In the literature, the dominant notion is that conflicting viewpoints and interests arising from unequal power dynamics can be resolved through negotiation. This study examined COPD patients, health professionals, and physician experiences of negotiation within 10 interprofessional collaborative COPD care teams. Physicians, patients, and healthcare professionals each had strikingly different conceptions and experiences of negotiating their perspective with other team members. Our study suggests that negotiation is an idealized notion rather than a relational process embedded in interprofessional collaborative practice. Importantly, we found that the ability and opportunity to negotiate one's perspective is heavily influenced by one's position in the workplace division of labor and professional hierarchy. We conclude that "negotiation" is only one approach among many in navigating interprofessional relations. Further, the rhetorical and ideological appeal of "negotiation" may overstate its role in interactions in interprofessional care settings, and lead to a misunderstanding of the power dynamics at play. It may be naïve to assume team members can control their situation through the competitive assertion of their individual perspective in a rational debate. Unfortunately, adopting the language of negotiation uncritically may not offer relevant solutions to structural and collective problems within a healthcare workplace.

Residents, Responsibility, and Error: How Residents Learn to Navigate the Intersection.

PURPOSE: As a competency of Canadian postgraduate education, residents are expected to be able to promptly disclose medical errors and assume responsibility for and take steps to remedy these errors. How residents, vulnerable through their inexperience and hierarchical team position, navigate the highly emotional event of medical error is underexplored. This study examined how residents experience medical error and learn to become responsible for patients who have faced a medical error. METHOD: Nineteen residents from a breadth of specialties and years of training at a large Canadian university residency program were recruited to participate in semistructured interviews between July 2021 and May 2022. The interviews probed their experience of caring for patients who had experienced a medical error. Data collection and analysis were conducted iteratively using a constructivist grounded theory method with themes identified through constant comparative analysis. RESULTS: Participants described their process of conceptualizing error that evolved throughout residency. Overall, the participants described a framework for how they experienced error and learned to care for both their patients and themselves following a medical error. They outlined their personal development of understanding error, how role modeling influenced their thinking about error, their recognition of the challenge of navigating a workplace environment full of opportunities for error, and how they sought emotional support in the aftermath. CONCLUSIONS: Teaching residents to avoid making errors is important, but it cannot replace the critical task of supporting them both clinically and emotionally when errors inevitably occur. A better understanding of how residents learn to manage and become responsible for medical error exposes the need for formal training as well as timely, explicit discussion and emotional support both during and after the event. As in clinical management, graded independence in error management is important and should not be avoided because of faculty discomfort.

Expanding the advocacy lens: using photo-elicitation to capture patients' and physicians' perspectives about health advocacy.

Heath advocacy (HA) remains a difficult competency to train and assess, in part because practicing physicians and learners carry uncertainty about what HA means and we are missing patients' perspectives about the role HA plays in their care. Visual methods are useful tools for exploring nebulous topics in health professions education; using these participatory approaches with physicians and patients might counteract the identified training challenges around HA and more importantly, remedy the exclusion of patient perspectives. In this paper we share the verbal and visual reflections of patients and physicians regarding their conceptualizations of, and engagement in 'everyday' advocacy. In doing so, we reveal some of HA's hidden dimensions and what their images uncovered about the role of advocacy in patient care. Constructivist grounded theory guided data collection and analysis. Data was collected through semi-structured interviews and photo-elicitation, a visual research method that uses participant generated photographs to elicit participants knowledge and experiences around a particular topic. We invited patients living with chronic health conditions (n = 10) and physicians from diverse medical and surgical specialties (n = 14) to self-select photographs representing their experiences navigating HA in their personal and professional lives. Both groups found taking photographs useful for revealing the nuanced and circumstantial factors that either enabled or challenged their engagement in HA. While patients' photos highlighted their embodiment of HA, physicians' photos depicted HA as something quite elusive or as a complicated and daunting task. Photo-elicitation was a powerful tool in eliciting a diversity of perspectives that exist around the HA role and the work advocates perform; training programs might consider using visuals to augment teaching for this challenging competency.

"A whole other competence story": exploring faculty perspectives on the process of workplace-based assessment of entrustable professional activities.

The centrality of entrustable professional activities (EPAs) in competency-based medical education (CBME) is predicated on the assumption that low-stakes, high-frequency workplace-based assessments used in a programmatic approach will result in accurate and defensible judgments of competence. While there have been conversations in the literature regarding the potential of this approach, only recently has the conversation begun to explore the actual experiences of clinical faculty in this process. The purpose of this qualitative study was to explore the process of EPA assessment for faculty in everyday practice. We conducted 18 semi-structured interviews with Anesthesia faculty at a Canadian academic center. Participants were asked to describe how they engage in EPA assessment in daily practice and the factors they considered. Interviews were audio-recorded, transcribed, and analysed using the constant comparative method of grounded theory. Participants in this study perceived two sources of tension in the EPA assessment process that influenced their scoring on official forms: the potential constraints of the assessment forms and the potential consequences of their assessment outcome. This was particularly salient in circumstances of uncertainty regarding the learner's level of competence. Ultimately, EPA assessment in CBME may be experienced as higher-stakes by faculty than officially recognized due to these tensions, suggesting a layer of discomfort and burden in the process that may potentially interfere with the goal of assessment for learning. Acknowledging and understanding the nature of this burden and identifying strategies to mitigate it are critical to achieving the assessment goals of CBME.

Ecological interchangeability: supporting team adaptive expertise in moments of disruption.

While undesirable, unexpected disruptions offer unique opportunities to enact adaptive expertise. For adaptive expertise to flourish, individuals and teams must embrace both efficiency and adaptation. While some industries do it readily, others continue to struggle with the tension between efficiency and adaptation, particularly when otherwise stable situations are unexpectedly disrupted. For instance, in healthcare settings, the efficiency mandate for strict compliance with scopes of practice can deter teams from using the adaptive strategy of making their members interchangeable. Yet, interchangeability has been hinted as a key capacity of today' teams that are required to navigate fluid team structures. Because interchangeability - as an adaptive strategy - can generate antagonistic reactions, it has not been well studied in fluid teams. Thus, in this exploratory qualitative study we sought to gain insights into how interchangeability manifests when fluid teams from five different contexts (healthcare, emergency services, orchestras, military, and business) deal with disruptive events. According to our participants, successful interchangeability was possible when people knew how to work within one's role while being aware of their teammates' roles. However, interchangeability included more than just role switching. Interchangeability took various forms and was most successful when teams capitalized on the procedural, emotional, and social dimensions of their work. To reflect this added complexity, we refer to interchangeability in fluid teams as Ecological Interchangeability. We suggest that ecological interchangeability may become a desired feature in the training of adaptive expertise in teams, if its underlying properties and enabling mechanisms are more fully understood.

"The Most Crushing Thing": Understanding Resident Assessment Burden in a Competency-Based Curriculum.

Background: Competency-based medical education (CBME) was expected to increase the workload of assessment for graduate training programs to support the development of competence. Learning conditions were anticipated to improve through the provision of tailored learning experiences and more frequent, low-stakes assessments. Canada has adopted an approach to CBME called Competence by Design (CBD). However, in the process of implementation, learner anxiety and assessment burden have increased unexpectedly. To mitigate this unintended consequence, we need a stronger understanding of how resident assessment burdens emerge and function. Objective: This study investigates contextual factors leading to assessment burden on residents within the framework of CBD. Methods: Residents were interviewed about their experiences of assessment using constructivist grounded theory. Participants (n=21) were a purposive sample from operative and perioperative training programs, recruited from 6 Canadian medical schools between 2019 and 2020. Self-determination theory was used as a sensitizing concept to categorize findings on types of assessment burden. Results: Nine assessment burdens were identified and organized by threats to psychological needs for autonomy, relatedness, and competence. Burdens included: missed opportunities for self-regulated learning, lack of situational control, comparative assessment, lack of trust, constraints on time and resources, disconnects between teachers and learners, lack of clarity, unrealistic expectations, and limitations of assessment forms for providing meaningful feedback. Conclusions: This study contributes a contextual understanding of how assessment burdens emerged as unmet psychological needs for autonomy, relatedness, and competence, with unintended consequences for learner well-being and intrinsic motivation.

Faculty and resident perceptions of surgical resident workload in comparison to objective data.

BACKGROUND: Little is known of the way in which stakeholders in surgical education perceive trainee workload. METHODS: A web-based survey examining the perception of current resident workload (as a percentage of daytime activities) was distributed to the faculty and residents in a Canadian general surgery residency program. The analysis compared the trainee and faculty responses against a 660-hour resident workload observation dataset. RESULTS: A total of 17 residents and 16 faculty completed the survey (74%, 67% participation). The resident estimations of workload were accurate for task categories (r = 0.91) and individual tasks (r = 0.92). The faculty estimations were accurate for task category (r = 0.90) but less so for individual tasks (r = 0.78). The residents perceived that significantly less time was allocated toward educational activities than faculty. Both of the groups underestimated the amount of time spent on indirect patient care (IPC). CONCLUSION: The faculty overestimate educational tasks as a proportion of workload. Both of the groups underestimated IPC tasks. This information can guide resident training program design and be used to bridge gaps between resident and faculty perceptions of resident workload.

From distress to detachment: exploring how providing care for stigmatized patients influences the moral development of medical trainees.

In acute hospital settings, medical trainees are often confronted with moral challenges and negative emotions when caring for complex and structurally vulnerable patients. These challenges may influence the long term moral development of medical trainees and have significant implications for future clinical practice. Despite the importance of moral development to medical education, the topic is still relatively under-explored. To gain a deeper understanding of moral development in trainees, we conducted a qualitative exploration of how caring for a stigmatized population influences their moral development. Data were collected from 48 medical trainees, including observational field notes, supplemental interviews, and medical documentation from inpatient units of two urban teaching hospitals in a Canadian context. Utilizing a practice-based approach which draws on constructivist grounded theory, we conducted constant comparative coding and analysis. We found that caring for stigmatized populations appeared to trigger frustration in medical trainees, which often perpetuated feelings of futility as well as avoidance behaviours. Additionally, hospital policies, the physical learning environment, variability in supervisory practices, and perceptions of judgment and mistrust all negatively influenced moral development and contributed to apathy and moral detachment which has implications for the future. Recognizing the dynamic and uncertain nature of care for stigmatized patients, and addressing the influence of structural and material factors provide an opportunity to support moral experiences within clinical training, and to improve inequities.

Adapting despite "walls coming down": Healthcare providers' experiences of COVID-19 as an implosive adaptation.

INTRODUCTION: The COVID-19 pandemic has been a daunting exercise in adaptation for healthcare providers. While we are beginning to learn about the challenges faced by teams during the COVID-19 pandemic, what remains underexplored are the strategies team members used to adapt to these challenges. The goal of this study is therefore to explore how healthcare providers navigated and adapted to on-the-ground challenges imposed by COVID-19. METHODS: We interviewed 20 healthcare workers at various hospitals in Ontario, who provided care as part of clinical teams during the COVID-19 pandemic. Data were collected and analyzed following Constructivist Grounded Theory principles including iteration, constant comparison and theoretical sampling. RESULTS: Participants' accounts of their experiences revealed the process of 'implosive adaptation'. The 'reality check', the 'scramble' and the 'pivot' comprised this process. The reality check described the triggers, the scramble detailed the challenges they went through and the pivot prescribed the shifting of mindset as they responded to challenges. These stages were iterative, rather than linear, with blurred boundaries. DISCUSSION: According to our participants, not all adaptations have to be successful during a crisis. The language of reality check, scramble and pivot provides a framework for teams to talk about and make sense of their approaches to crisis, even beyond the COVID-19 pandemic.

Repeated use of rich pictures to explore changes in subjective experiences over time of patients with advanced cancer.

BACKGROUND: The combination of verbal and visual tools may help unravel the experiences of advanced cancer patients. However, most previous studies have focused on a specific symptom, at only one moment in time. We recently found that a specific visual tool, originating from systems thinking, that is, rich pictures (RPs), could provide a more comprehensive view of the experiences of patients with advanced cancer. AIMS: To examine whether the repeated use of RPs can make changes in subjective experiences of patients living with advanced cancer visible over time. METHODS AND RESULTS: We performed a prospective study with a generic qualitative approach that was mostly informed by the process of grounded theory. We invited patients to make an RP twice, at the start of the study, and again after 2 months. Both RP drawing sessions were directly followed by a semi-structured interview. Patients with all types of solid tumors, above the age of 18, and with a diagnosis of advanced, incurable cancer, were eligible. Eighteen patients participated and 15 patients were able to draw an RP twice. In eight RP-sets, considerable differences between the first and second RP were noticeable. Two patterns were distinguished: (1) a change (decline or improvement) in physical health (five patients), and/or (2) a change in the way patients related to cancer (three patients). CONCLUSION: RPs are a valuable qualitative research method that can be used to explore the experiences of patients with advanced cancer, not only at a single point in time but also over time.

Interchangeability in Military Interprofessional Health Care Teams: Lessons Into Collective Self-healing and the Benefits Thereof.

INTRODUCTION: Interchangeability-i.e., the capacity to change places with another-is necessary for military interprofessional health care teams (MIHTs) to provide around-the-clock patient care. However, while interchangeability is clearly a necessity for modern health care delivery, it raises uncomfortable questions for civilian health care teams where it is usually labeled as unsafe. This perception surfaces because interchangeability runs counter to some of health care's cultural beliefs including those around patient ownership and professional scopes of practice. It is, therefore, not surprising that little is known about whether and how some level of interchangeability can be harnessed to improve the productivity of health care teams overall. In this article, we explore the notion of interchangeability in the particular context of MIHTs given that these health care teams are familiar with it. This exploration will offer insights into how interchangeability could maximize civilian health care teams' capacity to adapt. MATERIALS AND METHODS: We conducted a secondary analysis of interview data as an analytic expansion: "the kind of study in which the researcher makes further use of a primary data set in order to ask new or emerging questions that derive from having conducted the original analysis but were not envisioned within the original scope of the primary study aims". Within our secondary analysis approach, we used thematic analysis as our analytical tool to describe (1) what interchangeability looks like in MIHT teams, (2) how it is fostered in MIHTs, and (3) how it is enacted in MIHTs. RESULTS: Interchangeability was realized in MIHTs when individual team members adapted to take on roles and/or tasks that were not clearly niched in their specific areas of expertise but instead drew on the broad foundation of their clinical skill set. Cross-training and distributed leadership were ways in which MIHT members described how interchangeability was fostered. Furthermore, five features of working within MIHT teams were identified as key conditions to enact interchangeability: knowing your team members; being able to work with what/who you have; actively seeking others' expertise; situating your role within the broader picture of the mission; and maintaining a learning/teaching mindset. CONCLUSIONS: Interchangeability can be understood through the theoretical lens of Swarm Intelligence and more specifically, the principle of collective self-healing-which is the ability of collectives to continue to successfully perform despite disruption, challenges, or the loss of a team member. Our findings highlight how MIHTs have adopted interchangeability in a wide array of contexts to realize collective self-healing. Despite the discomfort it provokes, we suggest that interchangeability could be a powerful asset to civilian health care teams.
