The Utilisation, Application, and Quality of Videos of Clinical Interventions in Peer-Reviewed Literature: A Scoping Review

BACKGROUND

Videos of clinical interventions (VoCIs) demonstrating surgical and interventional procedures have become a mainstay in clinical practice and peer-reviewed academic literature. Despite the widespread availability of VoCI in the literature, there remain no established guidelines regarding the reporting of VoCI. We undertook a scoping review to investigate the current utilisation, application, and quality in VoCI reporting.

SUMMARY

A comprehensive literature search of Medline, Embase, Emcare, and CINAHL databases was performed to retrieve articles presenting VoCI, from January 2020 to December 2023. A customised data extraction tool assessed video characteristics (e.g., case presentation, outcomes), utility (e.g., target audience, reproducibility of procedure), and quality (subjective and objective). A total of 624 VoCIs were included (mean length 06:06), with over 62 h of VoCI reviewed. The most common VoCI perspectives were endoscopic (n = 153; 25%) and laparoscopic (n = 140; 22%). The clinical background and outcomes were described in 480 (76.9%) and 403 cases (64.6%), respectively, with disclosures (n = 23; 3.8%) rarely presented. VoCI primarily targeted trainees (n = 547; 87.7%) with most videos providing technical guidance (n = 394; 63.1%). In total, 248 videos (40%) were rated as medium or low quality on subjective assessment.

KEY MESSAGES

There are significant heterogeneity and notably poor-quality control in VoCI reporting in peer-reviewed literature resulting in the omission of critical procedural steps and suboptimal visual quality. VoCI reporting guidelines are therefore urgently required to provide a set of minimum items that should be reported by clinicians when uploading VoCI.

Video recording in GI endoscopy

The current approach to procedure reporting in endoscopy aims to capture essential findings and interventions but inherently sacrifices the rich detail and nuance of the entire endoscopic experience. Endoscopic video recording (EVR) provides a complete archive of the procedure, extending the utility of the encounter beyond diagnosis and intervention, and potentially adding significant value to the care of the patient and the field in general. This white paper outlines the potential of EVR in clinical care, quality improvement, education, and artificial intelligence-driven innovation, and addresses critical considerations surrounding technology, regulation, ethics, and privacy. As with other medical imaging modalities, growing adoption of EVR is inevitable, and proactive engagement of professional societies and practitioners is essential to harness the full potential of this technology toward improving clinical care, education, and research.

Advancing healthcare practice and education via data sharing: demonstrating the utility of open data by training an artificial intelligence model to assess cardiopulmonary resuscitation skills

Health professional education stands to gain substantially from collective efforts toward building video databases of skill performances in both real and simulated settings. An accessible resource of videos that demonstrate an array of performances - both good and bad-provides an opportunity for interdisciplinary research collaborations that can advance our understanding of movement that reflects technical expertise, support educational tool development, and facilitate assessment practices. In this paper we raise important ethical and legal considerations when building and sharing health professions education data. Collective data sharing may produce new knowledge and tools to support healthcare professional education. We demonstrate the utility of a data-sharing culture by providing and leveraging a database of cardio-pulmonary resuscitation (CPR) performances that vary in quality. The CPR skills performance database (collected for the purpose of this research, hosted at UK Data Service's ReShare Repository) contains videos from 40 participants recorded from 6 different angles, allowing for 3D reconstruction for movement analysis. The video footage is accompanied by quality ratings from 2 experts, participants' self-reported confidence and frequency of performing CPR, and the demographics of the participants. From this data, we present an Automatic Clinical Assessment tool for Basic Life Support that uses pose estimation to determine the spatial location of the participant's movements during CPR and a deep learning network that assesses the performance quality.

Study protocol for a Prospective Observational study of Safety Threats and Adverse events in Trauma (PrO-STAT): a pilot study at a level-1 trauma centre in Canada

INTRODUCTION

Traumatic injuries are a significant public health concern globally, resulting in substantial mortality, hospitalisation and healthcare burden. Despite the establishment of specialised trauma centres, there remains considerable variability in trauma-care practices and outcomes, particularly in the initial phase of trauma resuscitation in the trauma bay. This stage is prone to preventable errors leading to adverse events (AEs) that can impact patient outcomes. Prior studies have identified common causes of these errors, including delayed diagnostics, disorganisation of staff, equipment issues and communication breakdowns, which collectively contribute to AEs. This study addresses gaps in understanding the root causes of these errors by evaluating the most frequent AEs in trauma care through real-time video reviews of resuscitations in the trauma bay. Insights from this evaluation will inform targeted interventions to improve procedural adherence, communication and overall team performance, ultimately reducing preventable errors and improving patient safety.

METHODS AND ANALYSIS

A prospective observational study will be conducted at St. Michael's Hospital, a level-1 trauma centre, to evaluate resuscitations in the trauma bay. All consecutive trauma team activations over 12 months will be included, with data collected using audio-visual recordings and physiological monitoring. A synchronised data capture and analysis platform will comprehensively assess AEs, errors and human and environmental factors during trauma resuscitations. The study aims to detect recurring error patterns, evaluate practice variations and correlate trauma team performance with in-hospital outcomes. Statistical analyses will include descriptive statistics, logistic regression models and multivariable analyses to identify associations and predictors of AEs and patient outcomes.

ETHICS AND DISSEMINATION

Institutional research ethics approval was obtained (SMH REB # 21-009). A modified consent model will be employed for participants. Staff, physicians and learners will be provided with information regarding the study and will have the option to opt-out or withdraw consent. Similarly, trauma patients and their next of kin will be informed about the study, with provisions for opting out or withdrawing consent within 48 hours of recording. Measures will be implemented to ensure data confidentiality, anonymity and respect for participants' autonomy and privacy. The study results will be shared through peer-reviewed journal publications and conference presentations, and key institutional stakeholders will be informed about developing strategies to improve patient safety in trauma care.

Patient public perspectives on digital colorectal cancer surgery (DALLAS)

INTRODUCTION

The importance of patient perspectives is increasingly appreciated in clinical practice and academia with formal engagement processes developing worldwide. Digital surgery encompasses intraoperative patient data (including surgical video) analysis and so requires public-patient involvement (PPI).

METHODS

Engagement events were conducted based on NIHR and GRIPP2 LF guidelines. Following informative talks on digital surgery, invited patients and patient relatives were split into focus groups regarding 1) Research; 2) Data; 3) Industry Involvement; and 4) Artificial Intelligence in surgery. Scribed feedback was thematically analysed by two researchers independently. A pre and post event survey was sought voluntarily.

RESULTS

36 participant perspectives were analysed. In general, patients were enthusiastic about having a voice in surgical research and sharing their journey, with most groups concluding that capturing this was most appropriate after treatment recovery. The use of patient data for surgical development (i.e. research and education) was endorsed unanimously for the purpose of future patient benefit when responsibly and transparently managed and the value of industry was acknowledged. From 30 pre/post surveys (all p > 0.05), participants afforded the greatest data (including video) ownership claim to the surgical team (52 %/48 %) versus patients (32 %/24 %) and the hospital (12 %/24 %). While most (73 %/80 %) agreed that AI should be applied in surgical care, most felt the surgeon most valuable (93 %/80 %) with participants disagreeing that AI should make diagnoses (57 %/64 %) or treat patients (70 %/70 %) without human input.

CONCLUSION

Patients capably represent stable views and expectations that can strengthen modern and evolving surgical development involving data privacy, ownership and management.

Feasibility of Wearable Sensors to Assess Cognitive Load During Clinical Performance: Lessons Learned and Blueprint for Success

INTRODUCTION

Cognitive load (CogL) is increasingly recognized as an important resource underlying operative performance. Current innovations in surgery aim to develop objective performance metrics via physiological monitoring from wearable digital sensors. Surgeons have access to consumer technology that could measure CogL but need guidance regarding device selection and implementation. To realize the benefits of surgical performance improvement these methods must be feasible, incorporating human factors usability and design principles. This paper aims to evaluate the feasibility of using wearable sensors to assess CogL, identify the benefits and challenges of implementing devices, and develop guidance for surgeons planning to implement wearable devices in their research or practice.

METHODS

We examined the feasibility of wearable sensors from a series of empirical studies that measured aspects of clinical performance relating to CogL. Across four studies, 84 participants and five sensors were involved in the following clinical settings: (i) real intraoperative surgery; (ii) simulated laparoscopic surgery; and (iii) medical team performance outside the hospital.

RESULTS

Wearable devices worn on the wrist and chest were found to be comfortable. After a learning curve, electrodermal activity data were easily and reliably collected. Devices using photoplethysmography to determine heart rate variability were significantly limited by movement artifact. There was variable success with electroencephalography devices regarding connectivity, comfort, and usability.

CONCLUSIONS

It is feasible to use wearable sensors across various clinical settings, including surgery. There are some limitations, and their implementation is context and device dependent. To scale sensor use in clinical research, surgeons must embrace human factors principles to optimize wearability, usability, reliability, and data security.

The introduction of new technologies in current digestive surgical practice is progressively reshaping the operating room, defining the fourth surgical revolution. The implementation of black boxes and control towers aims at streamlining workflow and reducing surgical error by early identification and analysis, while augmented reality and artificial intelligence augment surgeons' perceptual and technical skills by superimposing three-dimensional models to real-time surgical images. Moreover, the operating room architecture is transitioning toward an integrated digital environment to improve efficiency and, ultimately, patients' outcomes. 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.

Characterizing nursing time with patients using computer vision

BACKGROUND

Compared to other providers, nurses spend more time with patients, but the exact quantity and nature of those interactions remain largely unknown. The purpose of this study was to characterize the interactions of nurses at the bedside using continuous surveillance over a year long period.

METHODS

Nurses' time and activity at the bedside were characterized using a device that integrates the use of obfuscated computer vision in combination with a Bluetooth beacon on the nurses' identification badge to track nurses' activities at the bedside. The surveillance device (AUGi) was installed over 37 patient beds in two medical/surgical units in a major urban hospital. Forty-nine nurse users were tracked using the beacon. Data were collected 4/15/19-3/15/20. Statistics were performed to describe nurses' time and activity at the bedside.

RESULTS

A total of n = 408,588 interactions were analyzed over 670 shifts, with >1.5 times more interactions during day shifts (n = 247,273) compared to night shifts (n = 161,315); the mean interaction time was 3.34 s longer during nights than days (p < 0.0001). Each nurse had an average of 7.86 (standard deviation [SD] = 10.13) interactions per bed each shift and a mean total interaction time per bed of 9.39 min (SD = 14.16). On average, nurses covered 7.43 beds (SD = 4.03) per shift (day: mean = 7.80 beds/nurse/shift, SD = 3.87; night: mean = 7.07/nurse/shift, SD = 4.17). The mean time per hourly rounding (HR) was 69.5 s (SD = 98.07) and 50.1 s (SD = 56.58) for bedside shift report.

DISCUSSION

As far as we are aware, this is the first study to provide continuous surveillance of nurse activities at the bedside over a year long period, 24 h/day, 7 days/week. We detected that nurses spend less than 1 min giving report at the bedside, and this is only completed 20.7% of the time. Additionally, hourly rounding was completed only 52.9% of the time and nurses spent only 9 min total with each patient per shift. Further study is needed to detect whether there is an optimal timing or duration of interactions to improve patient outcomes.

CLINICAL RELEVANCE

Nursing time with the patient has been shown to improve patient outcomes but precise information about how much time nurses spend with patients has been heretofore unknown. By understanding minute-by-minute activities at the bedside over a full year, we provide a full picture of nursing activity; this can be used in the future to determine how these activities affect patient outcomes.

Current trends and barriers to video management and analytics as a tool for surgeon skilling

BACKGROUND

The benefits of intraoperative recording are well published in the literature; however, few studies have identified current practices, barriers, and subsequent solutions. The objective of this study was to better understand surgeon's current practices and perceptions of video management and gather blinded feedback on a new surgical video recording product with the potential to address these barriers effectively.

METHODS

A structured questionnaire was used to survey 230 surgeons (general, gynecologic, and urologic) and hospital administrators across the US and Europe regarding their current video recording practices. The same questionnaire was used to evaluate a blinded concept describing a new intraoperative recording solution.

RESULTS

54% of respondents reported recording eligible cases, with the majority recording less than 35% of their total eligible caseload. Reasons for not recording included finding no value in recording simple procedures, forgetting to record, lack of access to equipment, legal concerns, labor intensity, and difficulty accessing videos. Among non-recording surgeons, 65% reported considering recording cases to assess surgical techniques, document practice, submit to conferences, share with colleagues, and aid in training. 35% of surgeons rejected recording due to medico-legal concerns, lack of perceived benefit, concerns about secure storage, and price. Regarding the concept of a recording solution, 74% of all respondents were very likely or quite likely to recommend the product for adoption at their facility. Appealing features to current recorders included the product's ease of use, use of AI to maintain patient and staff privacy, lack of manual downloads, availability of full-length procedural videos, and ease of access and storage. Non-recorders found the immediate access to videos and maintenance of patient/staff privacy appealing.

CONCLUSION

Tools that address barriers to recording, accessing, and managing surgical case videos are critical for improving surgical skills. Touch Surgery Enterprise is a valuable tool that can help overcome these barriers.

Enhancing surgical performance in cardiothoracic surgery with innovations from computer vision and artificial intelligence: a narrative review

When technical requirements are high, and patient outcomes are critical, opportunities for monitoring and improving surgical skills via objective motion analysis feedback may be particularly beneficial. This narrative review synthesises work on technical and non-technical surgical skills, collaborative task performance, and pose estimation to illustrate new opportunities to advance cardiothoracic surgical performance with innovations from computer vision and artificial intelligence. These technological innovations are critically evaluated in terms of the benefits they could offer the cardiothoracic surgical community, and any barriers to the uptake of the technology are elaborated upon. Like some other specialities, cardiothoracic surgery has relatively few opportunities to benefit from tools with data capture technology embedded within them (as is possible with robotic-assisted laparoscopic surgery, for example). In such cases, pose estimation techniques that allow for movement tracking across a conventional operating field without using specialist equipment or markers offer considerable potential. With video data from either simulated or real surgical procedures, these tools can (1) provide insight into the development of expertise and surgical performance over a surgeon's career, (2) provide feedback to trainee surgeons regarding areas for improvement, (3) provide the opportunity to investigate what aspects of skill may be linked to patient outcomes which can (4) inform the aspects of surgical skill which should be focused on within training or mentoring programmes. Classifier or assessment algorithms that use artificial intelligence to 'learn' what expertise is from expert surgical evaluators could further assist educators in determining if trainees meet competency thresholds. With collaborative efforts between surgical teams, medical institutions, computer scientists and researchers to ensure this technology is developed with usability and ethics in mind, the developed feedback tools could improve cardiothoracic surgical practice in a data-driven way.

In this second part of the series, we review into practical applications of video-based coaching, focusing on quality improvements in a team-based setting, such as the trauma bay. Additionally, we address the potential risks associated with surgical video recording, storage, and distribution, particularly regarding medicolegal aspects. We propose a comprehensive framework to facilitate the implementation of video coaching within individual healthcare institutions.

RESULTS

Our paper examines the legal and ethical framework and explores the potential benefits and challenges, offering insights into the real-world implications of this educational approach.

CONCLUSION

This paper contributes to the discourse on integrating video-based coaching into continuous professional development. It aims to facilitate informed decision-making in healthcare institutions, considering the adoption of this innovative educational quality tool.

Ethical perspectives on surgical video recording for patients, surgeons and society: systematic review

BACKGROUND

Operating-room audiovisual recording is increasingly proposed, although its ethical implications need elucidation. The aim of this systematic review was to examine the published literature on ethical aspects regarding operating-room recording.

METHODS

MEDLINE (via PubMed), Embase, and Cochrane databases were systematically searched for articles describing ethical aspects regarding surgical (both intracorporeal and operating room) recording from database inception to the present (the last search was undertaken in July 2022). Medical subject headings used in the search included 'operating room', 'surgery', 'video recording', 'black box', 'ethics', 'consent', 'confidentiality', 'privacy', and more. Title, abstract, and full-text screening determined relevance. The quality of studies was assessed using Centre for Evidence-Based Medicine grading and no formal assessment of risk of bias was attempted given the theoretical nature of the data collected.

RESULTS

From 1048 citations, 22 publications met the inclusion criteria, with three more added from their references. There was evident geographical (21 were from North America/Europe) and recency (all published since 2010) bias and an exclusive patient/clinician perspective (25 of 25). The varied methodology (including ten descriptive reviews, seven opinion pieces, five surveys, two case reports, and one RCT) and evidence level (14 level V and 10 level III/IV) prevented meaningful systematic grading/meta-analysis. Publications were narratively analysed for ethical thematic content (mainly education, performance, privacy, consent, and ownership) that was then grouped by the four principles of biomedical ethics of Beauchamp and Childress, accounting for 63 distinct considerations concerning beneficence (22 of 63; 35 per cent), non-maleficence (17 of 63; 27 per cent), justice (14 of 63; 22 per cent), and autonomy (10 of 63; 16 per cent). From this, a set of proposed guidelines on the use of operative data is presented.

CONCLUSION

For a surgical video to be a truly valuable resource, its potential benefits must be more fully weighed against its potential disadvantages, so that any derived instruments have a solid ethical foundation. Universal, ethical, best-practice guidelines are needed to protect clinicians, patients, and society.

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.

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.

Intraoperative video recording in otolaryngology for surgical education: evolution and considerations

BACKGROUND

Otolaryngology is a surgical speciality well suited for the application of intraoperative video recording as an educational tool considering the number procedures within the speciality that utilize digital technology. Intraoperative recording has been utilized in endoscopic surgeries and in evaluating technique in mastoidectomy, myringotomy and grommet insertion. The impact of intra-operative video recording in otolaryngology education is vast in creating access to surgical videos for preparation outside the operating room to individualized coaching and assessment. The purpose of this project is to highlight the role of intraoperative video recording in otolaryngology training and elucidate the challenges and considerations associated with implementation.

METHODS

Related publications between 1999 to 2022 were reviewed from PubMed and Embase databases utilizing search terms "intraoperative videography," "video recording surgery," "otolaryngology," and "surgical education." 109 articles were screened independently by HB and SK, by title and abstract then full text review. 28 articles from the original search and 6 from the secondary reference review were included.

RESULTS

The application of intraoperative video recording is evident in otolaryngology surgeries including endoscopic sinus surgery, laryngeal surgery, and other endoscopic procedures. There have been significant advancements in recording tools, including devices that can capture the surgeon's perspective. The considerations and challenges identified with utilizing this educational tool were categorized into different themes including ethics/consent, regulation, liability, data, technology, and human resources.

CONCLUSION

Intra-operative video recording has been demonstrated to have significant impact within otolaryngology education. It is critical to elucidate the challenges and considerations involved to utilize this educational tool effectively. Future directives will see video-based performance analytics providing comparative metrics to encourage precise coaching of surgical residents.

Feasibility of video assessment of operative skills in FCPS vascular surgery

Objective

To explore the feasibility of assessment of operative skills of FCPS vascular surgery trainees based on video recordings of the surgical procedures with a view to introduce it in the curriculum.

Methods

This qualitative study was carried out from 9th April 2021 - 15th July 2021 at Shifa Tameer e Millat University, Islamabad, Pakistan. It is a qualitative study based on constructivist grounded theory. Semi structured interviews of 16 participants, including five vascular surgical trainees, six vascular surgical consultants/supervisors/examiners, and five medical educationists were conducted, recorded and transcribed. Open and axial coding method was employed to identify recurring themes.

Results

Six themes could be identified. (1) There was consensus among participants on deficiency in current assessment of surgical skills. (2) Most participants believed that this is a useful method, although four out of 16 participants believed that current methods were sufficient. (3) There was a unanimous opinion that its purpose should be initially formative assessment and later for summative assessment. (4) It was suggested that it is practical with logistic support; it can be made part of trainee's record to be reviewed later; maybe by independent observers. (5) Participants believed that the logistic issue in term of equipment and trained manpower will be a challenge in implementing this mode of assessment. Other barriers included medicolegal and ethical issue and acceptability by the stake holders. (6) Participants also suggested remedies for the barriers.

Conclusion

Video review of surgical procedures can improve assessment of operative skills of trainees provided it is used as formative tool initially with a need to overcome logistics, medicolegal and cultural barriers.

Health care workers' experiences of video-based monitoring of hand hygiene behaviors: a qualitative study

BACKGROUND

Hand hygiene is key to preventing health care-associated infections. Human observation is the gold standard for measuring compliance, but its utility is increasingly being questioned with calls for the use of video monitoring approaches. The utility of video-based systems to measure compliance according to the WHO 5 moments is largely unexamined, as is its acceptability amongst health care workers (HCW) and patients. This study examined HCW acceptability of video monitoring for hand hygiene auditing.

METHODS

Following trial of a video monitoring system (reported elsewhere), 5 participating HCW attended 2 in-depth group interviews where they reviewed the footage and explored responses to the approach. Transcripts were analyzed using thematic analysis.

RESULTS

Four themes were identified: 1) Fears; 2) Concerns for patients; 3) Changes to feedback; and 4) Behavioral responses to the cameras. HCWs expressed fears of punitive consequences, data security, and confidentiality. For patients, HCWs raised issues regarding invasion of privacy, ethics, and consent. HCWs suggested that video systems may result in less immediate feedback but also identified potential to use the footage for feedback. They also suggested that the Hawthorne Effect was less potent with video systems than human observation.

CONCLUSIONS

The acceptability of video monitoring systems for hand hygiene compliance is complex and has the potential to complicate practical implementation. Additionally, exploration of the acceptability to patients is warranted.

Computer vision in surgery: from potential to clinical value

Hundreds of millions of operations are performed worldwide each year, and the rising uptake in minimally invasive surgery has enabled fiber optic cameras and robots to become both important tools to conduct surgery and sensors from which to capture information about surgery. Computer vision (CV), the application of algorithms to analyze and interpret visual data, has become a critical technology through which to study the intraoperative phase of care with the goals of augmenting surgeons' decision-making processes, supporting safer surgery, and expanding access to surgical care. While much work has been performed on potential use cases, there are currently no CV tools widely used for diagnostic or therapeutic applications in surgery. Using laparoscopic cholecystectomy as an example, we reviewed current CV techniques that have been applied to minimally invasive surgery and their clinical applications. Finally, we discuss the challenges and obstacles that remain to be overcome for broader implementation and adoption of CV in surgery.

Analyzing and Discussing Human Factors Affecting Surgical Patient Safety Using Innovative Technology: Creating a Safer Operating Culture

INTRODUCTION

Surgical errors often occur because of human factor-related issues. A medical data recorder (MDR) may be used to analyze human factors in the operating room. The aims of this study were to assess intraoperative safety threats and resilience support events by using an MDR and to identify frequently discussed safety and quality improvement issues during structured postoperative multidisciplinary debriefings using the MDR outcome report.

METHODS

In a cross-sectional study, 35 standard laparoscopic procedures were performed and recorded using the MDR. Outcome data were analyzed using the automated Systems Engineering Initiative for Patient Safety model. The video-assisted MDR outcome report reflects on safety threat and resilience support events (categories: person, tasks, tools and technology, psychical and external environment, and organization). Surgeries were debriefed by the entire team using this report. Qualitative data analysis was used to evaluate the debriefings.

RESULTS

A mean (SD) of 52.5 (15.0) relevant events were identified per surgery. Both resilience support and safety threat events were most often related to the interaction between persons (272 of 360 versus 279 of 400). During the debriefings, communication failures (also category person) were the main topic of discussion.

CONCLUSIONS

Patient safety threats identified by the MDR and discussed by the operating room team were most frequently related to communication, teamwork, and situational awareness. To create an even safer operating culture, educational and quality improvement initiatives should aim at training the entire operating team, as it contributes to a shared mental model of relevant safety issues.

Perceptions of safety culture and recording in the operating room: understanding barriers to video data capture

OBJECTIVE

Recording in the operating room is an important tool to help surgical teams improve their performance. This is becoming more feasible using the Operating Room Black Box, a comprehensive data capture platform. Operating room (OR) staff, however, may voice reasonable concerns as recording initiatives are implemented. The objective of this study was to assess pre-implementation attitudes of OR staff toward operative recording and explore the relationship of these attitudes to the themes of (1) safety culture, (2) impostor syndrome, and (3) privacy concerns.

METHODS

This cross-sectional survey study measured staff members' beliefs and opinions of operative recording and used three previously validated tools (safety attitudes questionnaire, clance impostor phenomenon scale, and dispositional privacy concern) to assess personal and professional factors. Concepts were correlated using Pearson's correlation coefficient.

RESULTS

Forty-three staff members participated in this study, with a response rate of 45% (n = 43/96, 20/22 nurses, 9/11 gynecologists, 14/63 anesthesiologists). Opinions of operative data capture were generally positive (5-point Likert scale, mean = 3.81, SD = 0.91). Nurses tended to have more favorable opinions of the OR Black Box as compared to gynecologists and anesthesiologists, though this did not reach statistical significance (4.15 vs. 3.67 vs 3.43, p = 0.06). Impostor syndrome characteristics correlated with concerns about litigation related to recording (r =  - 0.32, p = 0.04).

CONCLUSION

There are personal and professional attributes of the OR team that impact perceptions of the OR Black Box and implications around privacy and litigation. Addressing these concerns may facilitate successful implementation of the OR Black Box and improve team communication and patient safety in the OR.

Hybrid Spatiotemporal Contrastive Representation Learning for Content-Based Surgical Video Retrieval

In the medical field, due to their economic and clinical benefits, there is a growing interest in minimally invasive surgeries and microscopic surgeries. These types of surgeries are often recorded during operations, and these recordings have become a key resource for education, patient disease analysis, surgical error analysis, and surgical skill assessment. However, manual searching in this collection of long-term surgical videos is an extremely labor-intensive and long-term task, requiring an effective content-based video analysis system. In this regard, previous methods for surgical video retrieval are based on handcrafted features which do not represent the video effectively. On the other hand, deep learning-based solutions were found to be effective in both surgical image and video analysis, where CNN-, LSTM- and CNN-LSTM-based methods were proposed in most surgical video analysis tasks. In this paper, we propose a hybrid spatiotemporal embedding method to enhance spatiotemporal representations using an adaptive fusion layer on top of the LSTM and temporal causal convolutional modules. To learn surgical video representations, we propose exploring the supervised contrastive learning approach to leverage label information in addition to augmented versions. By validating our approach to a video retrieval task on two datasets, Surgical Actions 160 and Cataract-101, we significantly improve on previous results in terms of mean average precision, 30.012 ± 1.778 vs. 22.54 ± 1.557 for Surgical Actions 160 and 81.134 ± 1.28 vs. 33.18 ± 1.311 for Cataract-101. We also validate the proposed method’s suitability for surgical phase recognition task using the benchmark Cholec80 surgical dataset, where our approach outperforms (with 90.2% accuracy) the state of the art.

Methodological and technical considerations for video-based auditing of hand hygiene compliance in clinical practice: an exploratory study

BACKGROUND

Direct observation is the gold standard method for measuring hand hygiene compliance but its utility is increasingly being questioned. Various alternative electronic methods have been proposed, yet there is a paucity of research examining the use of these according to the World Health Organization's (WHO) '5 Moments for Hand Hygiene'. As a part of the process of developing a video-based monitoring system (VMS) capable of measuring hand hygiene compliance against the 5 moments criteria this paper reports methodological and technical issues that might arise from the use of a VMS for auditing in clinical practice.

METHODS

In-depth semi-structured interviews were conducted with 27 Australian content experts in hand hygiene auditing and infection prevention to explore their responses to proposed VMS auditing approaches. Transcripts were analyzed using thematic and content analysis.

RESULTS

Technical and methodological considerations for the use of VMS were interrelated and included concerns surrounding privacy, footage security, fears of surveillance and the potential for medico-legal consequences. Additionally, possible detrimental impacts on healthcare worker (HCW) -patient relationships, issues of cost versus benefits, HCW and patient safety and changes to feedback were also identified.

CONCLUSIONS

The primary methodological and technical issues to overcome in order to implement VMS for hand hygiene auditing in clinical practice, centered upon issues of acceptability to patients and health professionals, privacy, consent and liability.

A Review on the Current Applications of Artificial Intelligence in the Operating Room

Background. Artificial intelligence (AI) is an era upcoming in medicine and, more recently, in the operating room (OR). Existing literature elaborates mainly on the future possibilities and expectations for AI in surgery. The aim of this study is to systematically provide an overview of the current actual AI applications used to support processes inside the OR. Methods. PubMed, Embase, Cochrane Library, and IEEE Xplore were searched using inclusion criteria for relevant articles up to August 25th, 2020. No study types were excluded beforehand. Articles describing current AI applications for surgical purposes inside the OR were reviewed. Results. Nine studies were included. An overview of the researched and described applications of AI in the OR is provided, including procedure duration prediction, gesture recognition, intraoperative cancer detection, intraoperative video analysis, workflow recognition, an endoscopic guidance system, knot-tying, and automatic registration and tracking of the bone in orthopedic surgery. These technologies are compared to their, often non-AI, baseline alternatives. Conclusions. Currently described applications of AI in the OR are limited to date. They may, however, have a promising future in improving surgical precision, reduce manpower, support intraoperative decision-making, and increase surgical safety. Nonetheless, the application and implementation of AI inside the OR still has several challenges to overcome. Clear regulatory, organizational, and clinical conditions are imperative for AI to redeem its promise. Future research on use of AI in the OR should therefore focus on clinical validation of AI applications, the legal and ethical considerations, and on evaluation of implementation trajectory.

The age of surgical operative video big data - My bicycle or our park?

BACKGROUND

Surgery is a major component of health-care provision. Operative intervention often employs minimally invasive approaches incorporating digital cameras creating a 'digital twin' of both intracorporeal appearances and operative performance. Video recordings provide richer detail than the traditional operative note and can couple with advanced computer technology to unlock new analytic capabilities capable of driving surgical advancement via quality improvement initiatives and new technology design. Surgical video is however an under-utilized technology resource, in part, because ownership along with broader issues including purpose, privacy, confidentiality, copyright and inclusion in outputs have been poorly considered using outdated categorisation.

METHOD

A first principles perspective on operative video classification as a useful public interest resource enshrining fundamental stakeholder (patients, physicians, institutions, industry and society) rights, roles and responsibilities.

RESULT

A facility of noble purpose, understandable to all, for fair, accountable, safe and transparent access to large volumes of anonymised surgical videos of intracorporeal operations that enables advances through cross-disciplinary research is proposed. Technology can be exploited to protect all relevant parties respecting both citizen data-rights and the special status doctor-patient relationship. Through general consensus, the capability can be understood, established and iterated to perfection.

CONCLUSION

Overall we argue that new and specific classification of surgical video enables responsible curation and serves the public good better than the current model. Rather than being thought of as a bicycle where discrete ownership is ascribed, such data are better viewed as being more like a park, a regulated amenity we should preserve for better human life.

Video is better: why aren't we using it? A mixed-methods study of the barriers to routine procedural video recording and case review

INTRODUCTION

Video-based case review for minimally invasive surgery is immensely valuable for education and quality improvement. Video review can improve technical performance, shorten the learning curve, disseminate new procedures, and improve learner satisfaction. Despite these advantages, it is underutilized in many institutions. So far, research has focused on the benefits of video, and there is relatively little information on barriers to routine utilization.

METHODS

A 36-question survey was developed on video-based case review and distributed to the SAGES email list. The survey included closed and open-ended questions. Numeric responses and Likert scales were compared with t-test; open-ended responses were reviewed qualitatively through rapid thematic analysis to identify themes and sub-themes.

RESULTS

642 people responded to the survey for a response rate of 11%. 584 (91%) thought video would improve the quality of educational conferences. 435 qualitative responses on the value of video were analyzed, and benefits included (1) improved understanding, (2) increased objectivity, (3) better teaching, and (4) better audience engagement. Qualitative comments regarding specific barriers to recording and editing case video identified challenges at all stages of the process, from (1) the decision to record a case, (2) starting the recording in the OR, (3) transferring and storing files, and (4) editing the file. Each step had its own specific challenges.

CONCLUSION

Minimally invasive surgeons want to increase their utilization of video-based case review, but there are multiple practical challenges to overcome. Understanding these barriers is essential in order to increase use of video for education and quality improvement.

Deep learning for surgical phase recognition using endoscopic videos

BACKGROUND

Operating room planning is a complex task as pre-operative estimations of procedure duration have a limited accuracy. This is due to large variations in the course of procedures. Therefore, information about the progress of procedures is essential to adapt the daily operating room schedule accordingly. This information should ideally be objective, automatically retrievable and in real-time. Recordings made during endoscopic surgeries are a potential source of progress information. A trained observer is able to recognize the ongoing surgical phase from watching these videos. The introduction of deep learning techniques brought up opportunities to automatically retrieve information from surgical videos. The aim of this study was to apply state-of-the art deep learning techniques on a new set of endoscopic videos to automatically recognize the progress of a procedure, and to assess the feasibility of the approach in terms of performance, scalability and practical considerations.

METHODS

A dataset of 33 laparoscopic cholecystectomies (LC) and 35 total laparoscopic hysterectomies (TLH) was used. The surgical tools that were used and the ongoing surgical phases were annotated in the recordings. Neural networks were trained on a subset of annotated videos. The automatic recognition of surgical tools and phases was then assessed on another subset. The scalability of the networks was tested and practical considerations were kept up.

RESULTS

The performance of the surgical tools and phase recognition reached an average precision and recall between 0.77 and 0.89. The scalability tests showed diverging results. Legal considerations had to be taken into account and a considerable amount of time was needed to annotate the datasets.

CONCLUSION

This study shows the potential of deep learning to automatically recognize information contained in surgical videos. This study also provides insights in the applicability of such a technique to support operating room planning.

Identification of Meaningful Data for Providing Real-Time Intraoperative Feedback in Laparoscopic Surgery Using Delphi Analysis

Background. Surgeons are at risk of being overwhelmed with information while performing surgery. Initiatives focusing on the use of medical data in the operating room are on the rise. Currently, these initiatives require postprocessing of data. Although highly informative, data cannot be used to influence preventable error in real time. Ideally, feedback is provided preemptive. Aims. First, to identify which information is considered to be relevant for real-time feedback during laparoscopic surgery according to surgeons. Second, to identify the optimal routing for providing such feedback, and third, to decide on optimal timing for feedback to alarm users during laparoscopic surgery. Methods. A Delphi study of 3 iterations was conducted within the Amsterdam UMC, location AMC. A total of 25 surgeons and surgical residents performing laparoscopy were surveyed using 5-point Likert scales. Consensus was obtained when 80% of answers fitted the same answering category. Results. Delphi round 1 resulted in 198 unique ideas within 5 scenarios. After round 3, consensus was obtained on 102 items. Feedback most relevant during laparoscopic surgery refers to equipment like the gas insufflator, diathermy, and suction device. Feedback should be delivered via an additional monitor. Surgeons want to be instantly alarmed about aberrations in patients' vital parameters or combinations of vital parameters, preferably via a designated section on a monitor in their field of vision. Conclusions. Surgeons performing laparoscopy are uniform in their opinion that they need to be alarmed immediately when patients' vital parameters are becoming aberrant. Surgeons state that information regarding supporting equipment is best displayed on an additional monitor.

Pushing boundaries of video review in trauma: using comprehensive data to improve the safety of trauma care

Adverse events and lapses in safety are identified after the fact and often discussed through postevent review. These rounds rely on personal recollection, information from patient charts and incident reports that are limited by retrospective data collection. This results in recall bias and inaccurate or insufficient detail related to timeline, incidence and nature adverse events. To better understand the interplay of the complex team and task-based challenges in the trauma bay, we have developed a synchronized data capture and analysis platform called the Trauma Black Box (Surgical Safety Technologies, Toronto). This system continuously acquires audiovisual, patient physiological and environmental data from a sophisticated array of wall-mounted cameras, microphones and sensors. Expert analysts and software-based algorithms then populate a data timeline of case events from start to finish, retaining a handful of anonymized video clippings to supplement the review. These data also provide a consistent and reliable method to track specific quality metrics, such as time to trauma team assembly or time to blood product arrival. Furthermore, data can also be linked to patients’ electronic medical records to explore relationships between initial trauma resuscitation and downstream patient-oriented outcomes. A video capture and data analysis system for the trauma bay overcomes the inherent deficiencies in the current standard for evaluating patient care in the trauma bay and offers exciting potential to enhance patient safety through a comprehensive data collection system.

Implementing structured team debriefing using a Black Box in the operating room: surveying team satisfaction

Background

Surgical safety may be improved using a medical data recorder (MDR) for the purpose of postoperative team debriefing. It provides the team in the operating room (OR) with the opportunity to look back upon their joint performance objectively to discuss and learn from suboptimal situations or possible adverse events. The aim of this study was to investigate the satisfaction of the OR team using an MDR, the OR Black Box®, in the OR as a tool providing output for structured team debriefing.

Methods

In this longitudinal survey study, 35 gastro-intestinal laparoscopic operations were recorded using the OR Black Box® and the output was subsequently debriefed with the operating team. Prior to study, a privacy impact assessment was conducted to ensure alignment with applicable legal and regulatory requirements. A structured debrief model and an OR Back Box® performance report was developed. A standardized survey was used to measure participant’s satisfaction with the team debriefing, the debrief model used and the performance report. Factor analysis was performed to assess the questionnaire’s quality and identified contributing satisfaction factors. Multivariable analysis was performed to identify variables associated with participants’ opinions.

Results

In total, 81 team members of various disciplines in the OR participated, comprising 35 laparoscopic procedures. Mean satisfaction with the OR Black Box® performance report and team debriefing was high for all 3 identified independent satisfaction factors. Of all participants, 98% recommend using the OR Black Box® and the outcome report in team debriefing.

Conclusion

The use of an MDR in the OR for the purpose of team debriefing is considered to be both beneficial and important. Team debriefing using the OR Black Box® outcome report is highly recommended by 98% of team members participating.

Audio and panoramic video recording in the operating room: legal and ethical perspectives

INTRODUCTION

The idea of video recording (VR) in the operating room (OR) with panoramic cameras and microphones is a new concept that is changing the approach to medical activities in the OR. However, VR in the OR has brought up many concerns regarding patient privacy and has highlighted legal and ethical issues that were never previously exposed.

AIM

To review the literature concerning these aspects and provide a better ethical and legal understanding of the new challenges concerning VR in the OR.

CONCLUSIONS

There is a disparity between the two main legal models concerning VR in the OR, namely the European legal system (General Data Protection Regulation (GDPR)) and the American legal framework (Health Insurance Portability and Accountability Act (HIPAA)). This difference mainly deals with two distinct bioethical paradigms: GDPR places a strong emphasis on protecting patients' privacy to improve the public health system, whereas HIPAA indicates the need to generate protocols to safeguard the risks connected to medical activity and patient privacy. Following from this point, we may argue that, at the ethical and bioethical level, GDPR and HIPAA depend mainly on two different ethical models: a perspective based on moral acquaintances and weak proceduralism, respectively. It is worth noting the importance of developing additional guidelines concerning different world regions to avoid the ethical problems that may emerge when simply applying a foreign paradigm to a very different culture.
