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.

Exploring Knowledge, Skills, and Abilities Needed for Army Pharmacist Readiness Using the Nominal Group Technique.

INTRODUCTION: The purpose of this study was to conduct a general educational needs assessment to identify deficiencies in current Army pharmacy education while projecting future educational requirements based on changes in pharmacy practice and evolving demands of military medicine. MATERIALS AND METHODS: Twelve pharmacists participated in a facilitated discussion using the nominal group technique. Data were analyzed using quantitative and qualitative methods to establish consensus. Member checking was used to verify and validate the findings. RESULTS: Participants generated 190 knowledge, skill, and ability (KSA) statements over 3 sessions. Twenty-one statements achieved consensus. Four consensus statements were skills, 7 were knowledge, and 10 were abilities. KSAs were categorized into pharmaceutical care, military, logistics, or legal domain based on a thematic analysis. CONCLUSIONS: With modernized, relevant KSAs, the Army can measure and train a ready pharmacy force. Individual Critical Tasks augmented with KSAs are one potential approach we recommend as a strategy to improve Army pharmacist health profession education.

Physiologic measurements of cognitive load in clinical reasoning.

OBJECTIVES: Cognitive load is postulated to be a significant factor in clinical reasoning performance. Monitoring physiologic measures, such as heart rate variability (HRV) may serve as a way to monitor changes in cognitive load. The pathophysiology of why HRV has a relationship to cognitive load is unclear, but it may be related to blood pressure changes that occur in a response to mental stress. METHODS: Fourteen residents and ten attendings from Internal Medicine wore Holter monitors and watched a video depicting a medical encounter before completing a post encounter form used to evaluate their clinical reasoning and standard psychometric measures of cognitive load. Blood pressure was obtained before and after the encounter. Correlation analysis was used to investigate the relationship between HRV, blood pressure, self-reported cognitive load measures, clinical reasoning performance scores, and experience level. RESULTS: Strong positive correlations were found between increasing HRV and increasing mean arterial pressure (MAP) (p=0.01, Cohen's d=1.41). There was a strong positive correlation with increasing MAP and increasing cognitive load (Pearson correlation 0.763; 95 % CI [; 95 % CI [-0.364, 0.983]). Clinical reasoning performance was negatively correlated with increasing MAP (Pearson correlation -0.446; 95 % CI [-0.720, -0.052]). Subjects with increased HRV, MAP and cognitive load were more likely to be a resident (Pearson correlation -0.845; 95 % CI [-0.990, 0.147]). CONCLUSIONS: Evaluating HRV and MAP can help us to understand cognitive load and its implications on trainee and physician clinical reasoning performance, with the intent to utilize this information to improve patient care.

Exploring Impostor Phenomenon During Onboarding Into a Military Medical School.

INTRODUCTION: Impostor phenomenon (IP) is an experience where an individual believes that their success was because of chance or luck and was not associated with the mastery of skills. There is a gap in the literature in understanding what role, if any, onboarding (e.g., orientation weeks) into a military medical school plays into student experiences with IP. For many, onboarding serves as the first exposure to the climate, culture, and learning environment of both medical school and the military. Prevention, or early intervention, of IP may reduce potential effects on a medical trainee's confidence and competence in their profession, which may ultimately enhance health care team performance and impact patient outcomes. This study explores if and why military medical students experience IP during a 2-week-long orientation into a military medical school. MATERIALS AND METHODS: The study participants were medical students at a military medical school. Researchers conducted semi-structured interviews in August 2022 to explore if and why students experienced IP and deployed the Clance IP Scale as a measure with validity evidence for ascertaining the presence and magnitude of IP. Researchers calculated total scores from the Clance IP Scale and thematically analyzed interview transcripts. RESULTS: Researchers interviewed 29 matriculating military medical students. Twenty-one (75%) students reported frequent or intense IP experiences on the Clance IP Scale indicating that IP was present in our study sample. Thematic analysis identified six themes that drove one's experience with IP: reevaluation of merit, individualized diversity and inclusion experiences, administrative and financial support, preconceived expectations, building relationships, and new community roles. CONCLUSIONS: Our identified themes provide us with a better understanding of if and why military medical students experience IP during onboarding. Our findings are also consistent with the situated learning theory, which places emphasis on the sense of belonging and may provide a unique and insightful lens through which IP can be further explored and studied, particularly at a military medical school where various identities, dynamics, and aspirations can converge simultaneously. Additionally, our findings suggest that existing practices may benefit from a number of improvements including, but not limited to, tailoring onboarding activities to entail more reflective discussion using small groups, especially for topics related to diversity and inclusion, revisiting areas where students may feel inadequately prepared to transition and perform well in a medical school, reevaluating administrative and financial support that can be roadblocks to a student's transition into the new environment and removing these barriers, and ensuring cultural coherence (organizational alignment of vision and mission) among faculty, staff, and upperclassmen. Future research directions include better understanding how developing single or multiple, identities can impact a medical students' experience with IP during onboarding, pre-clerkship, clerkship, or post-clerkship period, if at all.
