ABSTRACT 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.

A class of poly(ethylene- co -methacrylic acid) (EMAA) copolymers and ionomers has shown the unique ability to instantaneously self-heal following ballistic puncture. It is noteworthy that the thermomechanical healing process active in these materials appears to be significantly different in capability and mechanism than any of the other self-repairing systems studied. To better understand this phenomenon, the thermal response during EMAA self-healing was examined. Tests of various damage types, including sawing, cutting and puncture, revealed high-energy transfer damage modes to produce heat and store energy favourable to healing. DSC probed healed specimens revealing they had reached the viscoelastic melt believed requisite to healing response. Low-temperature ballistic experiments demonstrated films continue healing even when punctured at −30°C; analysis showed healing efficacy comparable to room temperature, holding significant pressures of approximately 3 MPa. At the lowest temperature, brittle fracture occurred in one material indicating insufficient heat transfer to store recoverable energy. In total, the results supported the defined healing model and provided additional information on the healing process in both its thermal dependence and general mechanism. Finally, a new DSC method was developed for probing the thermal history of healed films which may lead to a more complete mechanistic model.
