Introduction of a surgical Black Box system in a hybrid angiosuite: Challenges and opportunities

Lead the room: Impact of leadership style on team resilience among trainees in the trauma bay

BACKGROUND

Leadership is a crucial component to successful team functioning in high-acuity scenarios. However, literature addressing the potential impact of leadership style on team members during trauma resuscitations is scarce. We aim to assess the link between leadership type and team resilience among trainees in the trauma bay through video review and hypothesize that transformational leadership would be predominant and positively linked with team member behaviors.

METHODS

We performed a single-center cross-sectional study of adult patients (14 years or older) presenting at our Level I trauma center. Trainee performance was evaluated with Behavior Anchored Rating Scales through post hoc audiovisual review of captured trauma resuscitations. Statistical analysis was performed to explore possible correlations between leadership style (transformational, transactional, and passive) and three team resilience behaviors (speaking up, knowledge sharing, and cooperation).

RESULTS

A total of 118 Level I and II trauma activations were analyzed. The average age was 34 [26-47] years, with 23% (n = 27) penetrating injuries, and an average Injury Severity Score of 12.5 [5-23.5]. Trauma leads scored highest on passive leadership (M = 2.96, SD = 1.16), followed by transactional (M = 2.67, SD = 1.29) and transformational (M = 2.33, SD = 1.19). Team members scored highest on knowledge sharing (M = 3.67, SD = 0.78) but lower on cooperation (M = 3.10, SD = 0.70) and speaking up (M = 3.10, SD = 1.17). Transformational and transactional leaderships were both positively correlated to the capacity in which team members cooperate (r = 0.53, p < 0.001 and r = 0.53, p < 0.001, respectively), share knowledge (r = 0.47, p < 0.001 and r = 0.47, p < 0.001, respectively), and speak up (r = 0.52, p < 0.001 and r = 0.49, p < 0.001, respectively). Passive leadership was negatively correlated with all three trauma team behaviors (p < 0.001).

CONCLUSION

Both transactional and transformational leaderships were positively associated with team resilience behaviors during trauma resuscitations. Opportunities for improvement among trainees suggest adopting an active rather than passive leadership style to promote team performance.

This narrative review describes the most recent evidence regarding the role of these technologies in transforming the current digestive surgical practice, underlining their potential benefits and drawbacks in terms of efficiency and patients' outcomes, as an attempt to foresee the digestive surgical practice of tomorrow.

Editor's Choice - Development and Testing of Step, Error, and Event Frameworks to Evaluate Technical Performance in Peripheral Endovascular Interventions

OBJECTIVE

Tools for endovascular performance assessment are necessary in competency based education. This study aimed to develop and test a detailed analysis tool to assess steps, errors, and events in peripheral endovascular interventions (PVI).

METHODS

A modified Delphi consensus was used to identify steps, errors, and events in iliac-femoral-popliteal endovascular interventions. International experts in vascular surgery, interventional radiology, cardiology, and angiology were identified, based on their scientific track record. In an initial open ended survey round, experts volunteered a comprehensive list of steps, errors, and events. The items were then rated on a five point Likert scale until consensus was reached with a pre-defined threshold (Cronbach's alpha > 0.7) and > 70% expert agreement. An experienced endovascular surgeon applied the finalised frameworks on 10 previously videorecorded elective PVI cases.

RESULTS

The expert consensus panel was formed by 28 of 98 invited proceduralists, consisting of three angiologists, seven interventional radiologists, five cardiologists, and 13 vascular surgeons, with 29% from North America and 71% from Europe. The Delphi process was completed after three rounds (Cronbach's alpha; αsteps = 0.79; αerrors = 0.90; αevents = 0.90), with 15, 26, and 18 items included in the final step (73 - 100% agreement), error (73 - 100% agreement), and event (73 - 100% agreement) frameworks, respectively. The median rating time per case was 4.3 hours (interquartile range [IQR] 3.2, 5 hours). A median of 55 steps (IQR 40, 67), 27 errors (IQR 21, 49), and two events (IQR 1, 6) were identified per case.

CONCLUSION

An evaluation tool for the procedural steps, errors, and events in iliac-femoral-popliteal endovascular procedures was developed through a modified Delphi consensus and applied to recorded intra-operative data to identify hazardous steps, common errors, and events. Procedural mastery may be promoted by using the frameworks to provide endovascular proceduralists with detailed technical performance feedback.

Interprofessional staff perspectives on the adoption of or black box technology and simulations to improve patient safety: a multi-methods survey

INTRODUCTION

Medical errors still plague healthcare. Operating Room Black Box (ORBB) and ORBB-simulation (ORBBSIM) are innovative emerging technologies which continuously capture as well as categorize intraoperative data, team information, and audio-visual files, in effort to improve objective quality measures. ORBB and ORBBSIM have an opportunity to improve patient safety, yet a paucity of implementation literature exists. Overcoming implementation barriers is critical. This study sought to obtain rich insights while identifying facilitators and barriers to adoption of ORBB and ORBBSIM in alignment with Donabedian's model of health services and healthcare quality. Enrichment themes included translational performance improvement and real-world examples to develop sessions.

METHODS

Interprofessional OR staff were invited to complete two surveys assessing staff's perceptions using TeamSTEPPS's validated Teamwork Perceptions Questionnaire (T-TPQ) and open-ended questions. Descriptive statistics were calculated for quantitative variables, and inductive phenomenological content analysis was used for qualitative.

RESULTS

Survey 1 captured 71 responses from 334 invited (RR 21%) while survey 2 captured 47 responses from 157 (RR 29.9%). The T-TPQ score was 65.2, with Communication (70.4) the highest construct and Leadership (58.0) the lowest. Quality Improvement (QI), Patient Safety, and Objective Case Review were the most common perceived ORBB benefits. Trends suggested a reciprocal benefit of dual ORBB and ORBBSIM adoption. Trends also suggested that dual implementation can promote Psychological Safety, culture, trust, and technology comfort. The need for an implementation plan built on change management principles and a constructive culture were key findings.

CONCLUSIONS

Findings supported ORBB implementation themes from previous literature and deepened our understanding through the exploration of team culture. This blueprint provides a model to help organizations adopt ORBB and ORBBSIM. Outcomes can establish an empirical paradigm for future studies.

Bias in artificial intelligence in vascular surgery

Application of artificial intelligence (AI) has revolutionized the utilization of big data, especially in patient care. The potential of deep learning models to learn without a priori assumption, or without prior learning, to connect seemingly unrelated information mixes excitement alongside hesitation to fully understand AI's limitations. Bias, ranging from data collection and input to algorithm development to finally human review of algorithm output affects AI's application to clinical patient presents unique challenges that differ significantly from biases in traditional analyses. Algorithm fairness, a new field of research within AI, aims to mitigate bias by evaluating the data at the preprocessing stage, optimizing during algorithm development, and evaluating algorithm output at the postprocessing stage. As the field continues to develop, being cognizant of the inherent biases and limitations related to black box decision making, biased data sets agnostic to patient-level disparities, wide variation of present methodologies, and lack of common reporting standards will require ongoing research to provide transparency to AI and its applications.

Surgeons' Leadership Style and Team Behavior in the Hybrid Operating Room: Prospective Cohort Study

OBJECTIVE

This study aimed to assess the relationship between surgeons' leadership style and team behavior in the hybrid operating room through video coding. Secondly, possible fluctuations possible fluctuations in leadership styles and team behavior during operative phases were studied.

BACKGROUND

Leadership is recognized as a key component to successful team functioning in high-risk industries. The 'full range of leadership' theory is commonly used to evaluate leadership, marking transformational, transactional, and passive. Few studies have examined the effects of these leadership styles on team behavior in surgery and/or their fluctuations during surgery.

METHODS

A single-center study included patients planned for routine endovascular procedures. A medical data capture system was used to allow post hoc video coding through Behavior Anchored Rating Scales. Multilevel statistical analysis was performed to assess possible correlations between leadership style and 3 team behavior indicators (speaking up, knowledge sharing, and collaboration) on an operative phase level.

RESULTS

Twenty-two cases were analyzed (47 hours recording). Transformational leadership is positively related to the extent to which team members work together (γ=0.20, P <0.001), share knowledge (γ=0.45, P <0.001), and speak up (γ=0.64, P <0.001). Passive leadership is significantly positively correlated with speaking up (γ=0.29, P =0.004). Leadership style and team behavior clearly fluctuate during a procedure, with similar patterns across different types of endovascular procedures.

CONCLUSIONS

Consistent with other professional fields, surgeons' transformational leadership enhances team behavior, especially during the most complex operative phases. This suggests that encouraging surgeons to learn and actively implement a transformational leadership style is meaningful to enhance patient safety and team performance.

Ethical and Legal Considerations for Recording in the Operating Room: A Systematic Review

INTRODUCTION

The integration of high-resolution video into surgical practice has fostered widespread interest in capturing surgical video recordings for the purposes of patient care, medical training, quality improvement, and documentation. The capture, analysis, and storing of such recordings inherently impact operating room (OR) activities and introduce potential harms to patients as well as members of the surgical team, which can be analyzed from both ethical and legal perspectives.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines, a systematic literature search of PubMed was conducted. The citations of included articles were then reviewed to find any articles not captured by our initial search.

RESULTS

62 Articles were included in the review (52 from PubMed search and 10 from citation review). Prevalent key issues in the literature at present include privacy, consent, ownership, legal use and discoverability, editing, data security, and recording's impact on the surgical team.

CONCLUSIONS

This review aims to spark proactive discussions of the ethical and legal implications of recording in the OR, which will guide transformation as the medical field adapts to new and innovative technologies without compromising its ideals or patient care.

Assessing endovascular team performances in a hybrid room using the Black Box system: a prospective cohort study

BACKGROUND

The hybrid room (HR) is a complex, high-risk environment, requiring teams (surgeons, anesthesiologists, nurses, technologists) to master various skills, including the 'As Low As Reasonably Achievable' principle of radiation safety. This prospective single center cohort reports the first use of the Operating Room Black Box (ORBB) in a HR. This medical data recording system captures procedural and audio-visual data to facilitate structured team performance analysis.

METHODS

Patients planned for endovascular repair of an infrarenal abdominal aortic aneurysm (EVAR) or treatment of symptomatic iliac-femoral-popliteal atherosclerotic disease (Peripheral Vascular Interventions or PVI) were included. Validated measures and established assessment tools were used to assess (non-)technical skills, radiation safety performance and environmental distractions.

RESULTS

Six EVAR and sixteen PVI procedures were captured. Technical performance for one EVAR was rated 19/35 on the procedure-specific scale, below the 'acceptable' score of 21. Technical skills were rated above acceptable in all PVI procedures. Shared decision making and leadership were rated highly in 12/22 cases, whereas surgical communication and nurses' task management were rated low in 14/22 cases. Team members rarely stepped back from the C-arm during digital subtraction angiography. Radiation safety behavior was scored below 'acceptable' in 14/22 cases. A median (interquartile range) number of 12 (6-23) auditory distractions was observed per procedure.

CONCLUSIONS

The ORBB facilitates holistic workplace-based assessment of endovascular performance in a HR by combining objective assessment parameters and rating scale-based evaluations. Strengths and weaknesses were identified in team members' (non-)technical and radiation safety practices. This technology has the potential to improve vascular surgical practice, though human input remains crucial. (NCT04854278).

Implementation of an Innovative Technology Called the OR Black Box: A Feasibility Study

Introduction. The operating room (OR) Black Box is an innovative technology that captures and compiles extensive real-time data from the OR, allowing identification and analysis of factors that influence intraoperative procedures and performances - ultimately improving patient safety. Implementation of this kind of technology is still an emerging research area and prone to face challenges. Methods. Observational study running from May 2017 to May 2021 conducted at Copenhagen University Hospital - Rigshospitalet, Denmark, involving 152 OR staff and 306 patients. Feasibility of the OR Black Box was assessed in accordance with Bowen's framework with 8 focus areas. Results. The OR Black Box had a high level of acceptability among stakeholders with 100% participation from management, 93% from OR staff, and 98% from patients. The implementation process improved over time, and an average of 80% of the surgeries conducted were captured. The practical aspects such as numerous formal and informal meetings, ethical and legal approval, recruitment of patients were acceptable, albeit time-consuming. The OR Black Box was adopted without any changes in scheduled surgery program, but capturing hours were adjusted to match the surgery program and relocation of OR staff declining to provide consent was possible. Conclusions. Implementation of the OR Black Box was feasible yet challenging. Management, nearly all staff, and patients embraced the initiative; however, ongoing evaluation, information meetings, and commitment from stakeholders are required and crucial to sustain momentum, continue implementation and expansion. Ideas from this study can be useful in the implementation of similar initiatives.
