The application of augmented reality in plastic surgery training and education: A narrative review

Continuing problems with fewer training opportunities and a greater awareness of patient safety have led to a constant search for an alternative technique to bridge the existing theory-practice gap in plastic surgery training and education. The current COVID-19 epidemic has aggravated the situation, making it urgent to implement breakthrough technological initiatives currently underway to improve surgical education. The cutting edge of technological development, augmented reality (AR), has already been applied in numerous facets of plastic surgery training, and it is capable of realizing the aims of education and training in this field. In this article, we will take a look at some of the most important ways that AR is now being used in plastic surgery education and training, as well as offer an exciting glimpse into the potential future of this field thanks to technological advancements.

Perceptions About Augmented Reality in Remote Medical Care: Interview Study of Emergency Telemedicine Providers

BACKGROUND

Augmented reality (AR) and virtual reality (VR) have increasingly appeared in the medical literature in the past decade, with AR recently being studied for its potential role in remote health care delivery and communication. Recent literature describes AR's implementation in real-time telemedicine contexts across multiple specialties and settings, with remote emergency services in particular using AR to enhance disaster support and simulation education. Despite the introduction of AR in the medical literature and its potential to shape the future of remote medical services, studies have yet to investigate the perspectives of telemedicine providers regarding this novel technology.

OBJECTIVE

This study aimed to understand the applications and challenges of AR in telemedicine anticipated by emergency medicine providers with a range of experiences in using telemedicine and AR or VR technology.

METHODS

Across 10 academic medical institutions, 21 emergency medicine providers with variable exposures to telemedicine and AR or VR technology were recruited for semistructured interviews via snowball sampling. The interview questions focused on various potential uses of AR, anticipated obstacles that prevent its implementation in the telemedicine area, and how providers and patients might respond to its introduction. We included video demonstrations of a prototype using AR during the interviews to elicit more informed and complete insights regarding AR's potential in remote health care. Interviews were transcribed and analyzed via thematic coding.

RESULTS

Our study identified 2 major areas of use for AR in telemedicine. First, AR is perceived to facilitate information gathering by enhancing observational tasks such as visual examination and granting simultaneous access to data and remote experts. Second, AR is anticipated to supplement distance learning of both minor and major procedures and nonprocedural skills such as cue recognition and empathy for patients and trainees. AR may also supplement long-distance education programs and thereby support less specialized medical facilities. However, the addition of AR may exacerbate the preexisting financial, structural, and literacy barriers to telemedicine. Providers seek value demonstrated by extensive research on the clinical outcome, satisfaction, and financial benefits of AR. They also seek institutional support and early training before adopting novel tools such as AR. Although an overall mixed reception is anticipated, consumer adoption and awareness are key components in AR's adoption.

CONCLUSIONS

AR has the potential to enhance the ability to gather observational and medical information, which would serve a diverse set of applications in remote health care delivery and education. However, AR faces obstacles similar to those faced by the current telemedicine technology, such as lack of access, infrastructure, and familiarity. This paper discusses the potential areas of investigation that would inform future studies and approaches to implementing AR in telemedicine.

Mixed reality for extraction of maxillary mesiodens

BACKGROUND

Mesiodentes are the most common supernumerary teeth. The cause is not fully understood, although proliferations of genetic factors and the dental lamina have been implicated. Mesiodentes can cause delayed or ectopic eruption of permanent incisors, which can further alter occlusion and appearance. Careful attention should be paid to the position and direction of the mesiodentes because of possible damage to adjacent roots in the permanent dentition period, errant extraction in the deciduous and mixed dentition periods, and damage to the permanent tooth embryo. To avoid these complications, we applied mixed reality (MR) technology using the HoloLens® (Microsoft, California). In this study, we report on three cases of mesiodentes extraction under general anesthesia using MR technology.

RESULTS

The patients ranged in age from 6 to 11 years, all three were boys, and the direction of eruption was inverted in all cases. The extraction approach was palatal in two cases and labial in one case. The average operative time was 32 min, and bleeding was minimal in all cases. No intraoperative or postoperative complications occurred. An image was shared preoperatively with all the surgeons using an actual situation model. Three surgeons used Microsoft HoloLens® during surgery, shared MR, and operated while superimposing the application image in the surgical field.

CONCLUSIONS

The procedure was performed safely; further development of MR surgery support systems in the future is suggested.

Learners' Responses to a Virtual Cadaver Dissection Nerve Course in the COVID Era: A Survey Study

Background  Virtual education is an evolving method for teaching medical learners. During the coronavirus disease 2019 pandemic, remote learning has provided a replacement for conferences, lectures, and meetings, but has not been described as a method for conducting a cadaver dissection. We aim to demonstrate how learners perceive a virtual cadaver dissection as an alternative to live dissection.

Methods  A virtual cadaver dissection was performed to demonstrate several upper extremity nerve procedures. These procedures were livestreamed as part of an educational event with multimedia and interactive audience questions. Participants were queried both during and after the session regarding their perceptions of this teaching modality.

Results  Attendance of a virtual dissection held for three plastic surgery training institutions began at 100 and finished with 70 participants. Intrasession response rates from the audience varied between 68 and 75%, of which 75% strongly agreed that they were satisfied with the virtual environment. The audience strongly agreed or agreed that the addition of multimedia captions (88%), magnified video loupe views (82%), and split-screen multicast view (64%) was beneficial. Postsession response rate was 27%, and generally reflected a positive perspective about the content of the session.

Conclusions  Virtual cadaver dissection is an effective modality for teaching surgical procedures and can be enhanced through technologies such as video loupes and multiple camera perspectives. The audience viewed the virtual cadaver dissection as a beneficial adjunct to surgical education. This format may also make in-person cadaver courses more effective by improving visualization and allowing for anatomic references to be displayed synchronously.

The Use of Live Streaming Technologies in Surgery: A Review of the Literature

BACKGROUND

Live streaming surgery is a developing communication platform in medicine. To maximize the technological advances that allow for the live streaming of surgery, it is crucial to have an understanding of the various video-capturing devices that are available and their pros and cons of implementation. Possible barriers to the widespread use of live streaming surgery include cost, concerns about patient safety and privacy, and limited understanding of the current available resources. In this article, we present the results of our literature review of techniques for live streaming of surgery as a means to inform readers and promote their implementation.

METHODS

We conducted a literature review of the literature to identify previous articles indexed in PubMed and Ovid. We used the following search terms: [Surgery AND Streaming], which generated 32 articles for initial review. References were reviewed within each document to find similar articles that were not captured by the initial search. The article selection criteria were peer-reviewed publications, case reports, and case series describing the use of live surgical streaming technologies.

RESULTS

Literature review showed enhanced surgeon interaction with viewers and improved anatomy scores with the widespread use of live streaming. Surgeons reported positive feedback and wished to engage in more sessions in the future. The largest barriers to implementation of streaming technology are video quality through the Internet and patient information protection.

CONCLUSIONS

Live streaming of surgery for educational purposes has not been widely accepted in surgical training programs to date. Streaming accessibility has advanced over the past 2 decades with the availability of handheld mobile devices. However, little has been done to allow for live streaming of surgery to trainees in a manner compliant with the Health Portability Insurance and Accountability Act.

How to Host a Virtual Educational Conference

SUMMARY

Virtual education is a promising tool for expanding surgical training and continuing education. The authors present their preferred platforms for virtual surgical education, and discuss security and privacy concerns. Maintaining communication and keeping sessions engaging require special consideration when education is done virtually. The limitations to virtual education may soon be mitigated by new technologies. In this article, the authors aim to describe the benefits, current modalities, tips for use, and future directions for virtual education as it pertains to plastic surgeons and trainees during the current coronavirus pandemic.

Compliance with the Surgery Safety Checklist: An Update on the Status

WHO has recommended the implementation of the Surgery Safety Checklist (SSC) to reign in often simple logistic errors that lead to numerous complications, some of them being fatal, in the perioperative period. This study aims to discuss doubts presented in the medical literature concerning the effectiveness of SSC in the currently existing form. The article is based on the literature search performed in PubMed using the command phrase "Surgery Safety Checklist". The search yielded 1,476 articles up to March 2021. Out of this group, we selected 811 articles for further detailed analysis. The selection was based on the meritorious SSC-related topicality and scrutinized content of the articles. Out of these articles, we identified 59 studies that specifically raised the issue of the effectiveness of SSC use in its current form, which we discussed herein in detail. The review distinctly indicates that the SSC reduces perioperative complications including fatalities. However, there are issues reported with the itemized content of the checklist that hardly corresponds to the diverseness of patients' conditions and operating room settings. Further, it is unclear if a reduction in the complications stems from the use of SSC or the algorithms for performing procedures it contains. The consensus arises that SSC should be periodically updated so that it would catch up with the advances in medical knowledge and the emerging technologies, which would safeguard the SSC from becoming just another paperwork nuisance for the operating room staff.

What Is Your Reality? Virtual, Augmented, and Mixed Reality in Plastic Surgery Training, Education, and Practice

SUMMARY

Virtual reality and other technological advancements both inside and outside the operating room have shown an exponential increase in the past two decades. Surgical technique and finesse in delicate procedures have become ever more important, and the onus is on plastic surgeons and plastic surgery residents to meet these needs to provide the best outcomes possible to patients. The ability to learn, simulate, and practice operating in a fashion that poses no harm to any patient is truly a gift from technology to surgery that any surgeon could benefit from, whether trainee or attending. This application of technology and simulation has been demonstrated in other fields such as in the airline industry with flight simulation. The ability to learn, synthesize, and incorporate learned materials and ideas through virtual, augmented, and mixed reality tools offers a great opportunity to put our field at the forefront of a paradigm shift in surgical education. The critical utility of digital education could not be further emphasized any more than in the unfortunate and infrequent situation of a worldwide pandemic. This article reviews some of the important recent technologies that have developed and their applications in plastic surgery education and offers a look into what we can expect in the future.

Osmo Pocket© vs VITOM®: comparison of surgical educational video recording means in head and neck reconstructive surgery

PURPOSE

To highlight the needs for better intraoperative educational video recording in head and neck reconstructive surgery and to provide some information to standardize camera positioning in operative room.

METHODS

The Authors compared the Osmo Pocket© and the VITOM® 0° Telescope, evaluating the faculty and trainees point of view through specific questionnaires. The study was performed during two Masterclasses on Head and Neck Reconstructive Surgery that took place in the Hospital Casa Sollievo della Sofferenza in 2018 e 2019. Camera positioning in the Operative Room was also assessed.

RESULTS

In the faculty group, Osmo Pocket© was reported as frequently interfering with surgical intervention; the need for repositioning was reported more frequently in recording with VITOM®, that was evaluated as better in keeping a good "recording flow". In trainees' group, the perceived image quality with VITOM® was more appreciated, while Osmo Pocket© was considered superior in surgical field vision. Regarding the systems' positioning in the OR, in all the surgical procedures it was observed the need for the first operator and the trainees to have the HD monitor placed in front of them. Only during forearm flap harvesting the HD monitor was placed laterally to the first operator and the trainees.

CONCLUSIONS

The Osmo Pocket© is a cheap solution and allows a stable and continuous vision of the operative field, without the needing for stop and repositioning. The Vitom®, despite its major costs and the needing for periodic repositioning, allows a better view of anatomical details with less discomfort for the surgeon. Moreover it's important a standardization of the video means positioning in the operative room to reduce the pre-operative times and to aid in the choice of the most useful method for educational video recording.

Case-specific three-dimensional hologram with a mixed reality technique for tumor resection in otolaryngology

OBJECTIVE

We report our first experience of using a case-specific three-dimensional (3D) hologram for tumor resection in otolaryngology to show the proof of concept. In addition, a questionnaire was administered to assess the usefulness of the mixed reality technique in otolaryngology.

METHODS

A case-specific 3D hologram was developed from enhanced images of dynamic computed tomography, with reference to contrast-enhanced magnetic resonance images, and used for preoperative planning and intraoperative image reference. To evaluate the usefulness of the 3D hologram with head mount displays (HMDs), 18 attendings and resident otolaryngologists completed a questionnaire with the Likert scale.

RESULTS

The case-specific 3D hologram on HMDs was successfully used by means of easy gesture-handling without any monitors preoperatively and intraoperatively. The experience of picturing the tumor localization and evaluating the surgical approach was statistically better using the 3D hologram on HMDs than using the computer images (P < .01). Similarly, the holograms were observed to be better for intraoperative application and surgical education than computer images (P < .01).

CONCLUSION

We demonstrated the use of a case-specific 3D hologram for tumor resection in otolaryngology. The technology may be useful for preoperative planning and intraoperative image reference, especially for challenging cases, and surgical education.

Smart Glasses as a Surgical Pathology Grossing Tool

CONTEXT.—

Smart glasses are a wearable technology that enable hands-free data acquisition and entry.

OBJECTIVE.—

To develop a surgical pathology grossing application on a smart glass platform.

DESIGN.—

An existing logistics software for the Google Glass Enterprise smart glass platform was used to create surgical pathology grossing protocols. The 2 grossing protocols were developed to simulate grossing a complex (heart) and a simple (kidney) specimen. For both protocols, users were visually prompted by the smart glass device to perform each task, record measurements, or document the field of view. In addition to measuring the total time of the protocol performance, each substep within the protocol was automatically recorded. Subsequently, a report was generated that contained the dictation, images, voice recordings, and the timing of each step. The application was tested by 3 users using the 2 grossing protocols. The users were tracked across 3 grossing procedures for each protocol.

RESULTS.—

For the complex specimen grossing the average time across repeated procedures was not significantly different between users (P > .99). However, when grossing times of the complex specimen were compared for repeated performances of the same user, a significant reduction in grossing times was observed with each repetition (P = .002). For the simple specimen, the average grossing time across multiple attempts was different among users (P = .03); however, no improvement in grossing time was observed with repeated performance (P = .499).

CONCLUSIONS.—

Augmented reality based grossing applications can provide automated data collection to track the changes in grossing performance over time.

Feasibility of Wearable Display Glasses for Medical Students in the Endoscopy Room

Background/Aims

Several attempts have been made to incorporate smart glasses in the medical field. We applied wearable display glasses to show the position of an observer during endoscopy and compared students’ responses between the conventional and new methods.

Methods

We surveyed 28 medical students regarding the use of wearable display devices. The students used wearable display glasses to observe an endoscopic procedure and answered the prepared questionnaire. Their collected responses were analyzed for statistical correlations between each variable.

Results

The survey of medical students revealed disadvantages including dizziness (dissatisfied and very dissatisfied: 21.5%) and eye fatigue (25% dissatisfied) and advantages including concentration (satisfied and very satisfied: 57.2%) and securing patient rights (71.4%). The students showed more positive than negative reviews regarding the new devices (32.1% vs. 21.5%).

Conclusions

We investigated the advantages and disadvantages of viewing the endoscope image with new wearable display glasses compared to the conventional method using the survey to record user experience. The results revealed relatively positive responses from the medical students in the survey. If the new device compensates for some shortcomings, its use in the endoscopy room will be feasible.

Microsurgery in the era of COVID-19

The COVID-19 pandemic has presented new challenges to microsurgeons. The virus is highly transmissible, with increased risk during operations that involve the aerodigestive tract. It is important to be able to identify high-risk operations and scenarios to guide management decisions and selection of personal protective equipment. Preoperative testing is a key element in identifying high-risk scenarios, and preoperative testing protocols are essential to maintaining safety in the COVID-19 era. Because COVID-19 can be transmitted via the conjunctiva, adaptations to loupes and microscopes are necessary to safely perform microsurgery in high-risk scenarios. We outline a potential risk stratification algorithm, as well as precautions for each scenario. Potential areas for innovation are also discussed.

The Art of Teaching, Training, and Putting the Scalpel in Residents' Hands

Surgical education is under tremendous pressure due to ever-increasing medical knowledge and demands on trainees' time. They must continually learn more in less time due to work hour limitations, regulations, and electronic medical record demands. Surgical training must become more efficient. There is an unprecedented array of education and training opportunities for resident preparation. The preparation for each case has to be maximal. Preoperative, intraoperative, and postoperative simulation and discussions improve the educational benefit of the trainee experience. For the teaching surgeon, putting a scalpel in residents' hands requires patience, knowledge, judgment, and a leap of faith in the resident.

Plastic Surgery Lockdown Learning during Coronavirus Disease 2019: Are Adaptations in Education Here to Stay?

Summary: The novel coronavirus disease 2019 has had a major impact on human life and livelihood. The unprecedented challenges have expanded beyond just social and work life, and have grown to impact resident education. In this article, we review the structure of plastic surgery education before the pandemic, the different online learning opportunities for self-directed learning. A summary of the range of platforms and approaches of online remote access delivery of conferences and education that emerged or expanded as a result of the crisis has been reported. This article highlighted the rapid initiatives and efforts of programs and national and international societies to support continuing medical education in conjunction with the guidelines to “shelter at home” and maintain social distancing, and possible future for expanding the reach of online academic initiatives, in addition to the role of developing virtual technologies. The coronavirus disease 2019 crisis has created an opportunity to analyze and advance online learning options to overcome the associated challenges and continue as a reliable platform even following the resolution of the social distancing requirements.

Use of Simulation in Plastic Surgery Training

The nationwide focus on patient safety and the health of residents has increased the demand for educational tools outside the operating room. Simulation is a valuable tool for assessing and developing surgical skills in a controlled and safe environment. The use of simulation as a formal component of training has been increasing in various surgical subspecialties. In general surgery, simulation examinations such as the Fundamentals of Laparoscopic Surgery and Fundamentals of Endoscopic Surgery have become a prerequisite to board certification. Although formal simulation examinations in plastic surgery are not universal, there has been an increase in the use of simulation to increase resident competency in the operating room. For now, we will review the current state of simulation in craniofacial, hand, microvascular, and esthetic surgery and discuss applications for the future. We will also discuss the evolving role of artificial intelligence, virtual reality, and augmented reality in plastic surgery training and testing.

Smart Glasses for Caring Situations in Complex Care Environments: Scoping Review

BACKGROUND

Anesthesia departments and intensive care units represent two advanced, high-tech, and complex care environments. Health care in those environments involves different types of technology to provide safe, high-quality care. Smart glasses have previously been used in different health care settings and have been suggested to assist health care professionals in numerous areas. However, smart glasses in the complex contexts of anesthesia care and intensive care are new and innovative. An overview of existing research related to these contexts is needed before implementing smart glasses into complex care environments.

OBJECTIVE

The aim of this study was to highlight potential benefits and limitations with health care professionals' use of smart glasses in situations occurring in complex care environments.

METHODS

A scoping review with six steps was conducted to fulfill the objective. Database searches were conducted in PubMed and Scopus; original articles about health care professionals' use of smart glasses in complex care environments and/or situations occurring in those environments were included. The searches yielded a total of 20 articles that were included in the review.

RESULTS

Three categories were created during the qualitative content analysis: (1) smart glasses as a versatile tool that offers opportunities and challenges, (2) smart glasses entail positive and negative impacts on health care professionals, and (3) smart glasses' quality of use provides facilities and leaves room for improvement. Smart glasses were found to be both a helpful tool and a hindrance in caring situations that might occur in complex care environments. This review provides an increased understanding about different situations where smart glasses might be used by health care professionals in clinical practice in anesthesia care and intensive care; however, research about smart glasses in clinical complex care environments is limited.

CONCLUSIONS

Thoughtful implementation and improved hardware are needed to meet health care professionals' needs. New technology brings challenges; more research is required to elucidate how smart glasses affect patient safety, health care professionals, and quality of care in complex care environments.

A Systematic Review of the Use of Google Glass in Graduate Medical Education

BACKGROUND

Graduate medical education (GME) has emphasized the assessment of trainee competencies and milestones; however, sufficient in-person assessment is often constrained. Using mobile hands-free devices, such as Google Glass (GG) for telemedicine, allows for remote supervision, education, and assessment of residents.

OBJECTIVE

We reviewed available literature on the use of GG in GME in the clinical learning environment, its use for resident supervision and education, and its clinical utility and technical limitations.

METHODS

We conducted a systematic review in accordance with 2009 PRISMA guidelines. Applicable studies were identified through a review of PubMed, MEDLINE, and Web of Science databases for articles published from January 2013 to August 2018. Two reviewers independently screened titles, abstracts, and full-text articles that reported using GG in GME and assessed the quality of the studies. A systematic review of these studies appraised the literature for descriptions of its utility in GME.

RESULTS

Following our search and review process, 37 studies were included. The majority evaluated GG in surgical specialties (n = 23) for the purpose of surgical/procedural skills training or supervision. GG was predominantly used for video teleconferencing, and photo and video capture. Highlighted positive aspects of GG use included point-of-view broadcasting and capacity for 2-way communication. Most studies cited drawbacks that included suboptimal battery life and HIPAA concerns.

CONCLUSIONS

GG shows some promise as a device capable of enhancing GME. Studies evaluating GG in GME are limited by small sample sizes and few quantitative data. Overall experience with use of GG in GME is generally positive.

Video Technologies for Recording Open Surgery: A Systematic Review

Video recording of surgical procedures is an important tool for surgical education, performance enhancement, and error analysis. Technology for video recording open surgery, however, is limited. The objective of this article is to provide an overview of the available literature regarding the various technologies used for intraoperative video recording of open surgery. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines using the MEDLINE, Cochrane Central, and EMBASE databases. Two authors independently screened the titles and abstracts of the retrieved articles, and those that satisfied the defined inclusion criteria were selected for a full-text review. A total of 2275 publications were initially identified, and 110 were included in the final review. The included articles were categorized based on type of article, surgical subspecialty, type and positioning of camera, and limitations identified with their use. The most common article type was primary-technical (29%), and the dominant specialties were general surgery (22%) and plastic surgery (18%). The most commonly cited camera used was the GoPro (30%) positioned in a head-mount configuration (60%). Commonly cited limitations included poor video quality, inadequate battery life, light overexposure, obstruction by surgical team members, and excessive motion. Open surgery remains the mainstay of many surgical specialties today, and technological innovation is absolutely critical to fulfill the unmet need for better video capture of open surgery. The findings of this article will be valuable for guiding future development of novel technology for this purpose.

Increasing Completion Rate and Benefits of Checklists: Prospective Evaluation of Surgical Safety Checklists With Smart Glasses

BACKGROUND

Studies have demonstrated that surgical safety checklists (SSCs) can significantly reduce surgical complications and mortality rates. Such lists rely on traditional posters or paper, and their contents are generic regarding the type of surgery being performed. SSC completion rates and uniformity of content have been reported as modest and widely variable.

OBJECTIVE

This study aimed to investigate the feasibility and potential of using smart glasses in the operating room to increase the benefits of SSCs by improving usability through contextualized content and, ideally, resulting in improved completion rates.

METHODS

We prospectively evaluated and compared 80 preoperative time-out events with SSCs at a major academic medical center between June 2016 and February 2017. Participants were assigned to either a conventional checklist approach (poster, memory, or both) or a smart glasses app running on Google Glass.

RESULTS

Four different surgeons conducted 41 checklists using conventional methods (ie, memory or poster) and 39 using the smart glasses app. The average checklist completion rate using conventional methods was 76%. Smart glasses allowed a completion rate of up to 100% with a decrease in average checklist duration of 18%.

CONCLUSIONS

Compared with alternatives such as posters, paper, and memory, smart glasses checklists are easier to use and follow. The glasses allowed surgeons to use contextualized time-out checklists, which increased the completion rate to 100% and reduced the checklist execution time and time required to prepare the equipment during surgical cases.

Feasibility of Telesimulation and Google Glass for Mass Casualty Triage Education and Training

Introduction

Our goal was to evaluate the feasibility and effectiveness of using telesimulation to deliver an emergency medical services (EMS) course on mass casualty incident (MCI) training to healthcare providers overseas.

Methods

We conducted a feasibility study to establish the process for successful delivery of educational content to learners overseas via telesimulation over a five-month period. Participants were registrants in an EMS course on MCI triage broadcast from University of California, Irvine Medical Simulation Center. The intervention was a Simple Triage and Rapid Treatment (START) course. The primary outcome was successful implementation of the course via telesimulation. The secondary outcome was an assessment of participant thoughts, feelings, and attitudes via a qualitative survey. We also sought to obtain quantitative data that would allow for the assessment of triage accuracy. Descriptive statistics were used to express the percentage of participants with favorable responses to survey questions.

Results

All 32 participants enrolled in the course provided a favorable response to all questions on the survey regarding their thoughts, feelings, and attitudes toward learning via telesimulation with wearable/mobile technology. Key barriers and challenges identified included dependability of Internet connection, choosing appropriate software platforms to deliver content, and intercontinental time difference considerations. The protocol detailed in this study demonstrated the successful implementation and feasibility of providing education and training to learners at an off-site location.

Conclusion

In this feasibility study, we were able to demonstrate the successful implementation of an intercontinental MCI triage course using telesimulation and wearable/mobile technology. Healthcare providers expressed a positive favorability toward learning MCI triage via telesimulation. We were also able to establish a process to obtain quantitative data that would allow for the calculation of triage accuracy for further experimental study designs.

Workflow efficiency pilot study of Surgery Viewer©: A secure hands-free intraoperative multimedia interface for Google Glass™

Background:

The Google Glass™ heads-up-display system has been adopted by the medical field for applications such as image capture, live streaming and decision support.

Methods:

We designed a custom application for Google Glass™ called Surgery Viewer^© to capture patient images and securely transfer them to the electronic medical record. Surgery Viewer^© was compared to a standard digital camera and an Apple iOS^© device using another image capture application. Comparative workflow metrics included timings of image capture and a usability survey.

Results:

Ten patients were studied in operating room and wound clinic settings. Average times to log in (Surgery Viewer^©, Image Capture™) or turn on (digital camera) were 18.39 s, 9.91 s and 2.11 s for Surgery Viewer^©, Image Capture™ and digital camera, respectively. In the operating room, the average times to select the correct patient were 3.06 s, 14.77 s and 4.45 s for Surgery Viewer^©, Image Capture™ and digital camera, respectively. Average image capture times were 8.67 s, 7.77 s and 7.60 s for Surgery Viewer^©, Image Capture™ and digital camera, respectively. Images captured by Surgery Viewer^© and Image Capture™ were instantaneously uploaded to the electronic medical record, but digital camera images took on average 1522 s to be uploaded. In the wound clinic, the average times to select the correct patient were 16.29 s, 7.35 s and 4.63 s for Surgery Viewer^©, Image Capture™ and digital camera, respectively. Image capture times were 9.55 s, 5.28 s and 3.47 s, respectively. Digital camera took on average 27,758 s to upload.

Conclusion:

Surgery Viewer^© performed equivalently with Image Capture™ while digital camera took longer to upload. Users found the application easy to learn with Surgery Viewer^© concerns, including log on procedure, ambient distraction from voice recognition, viewfinder perspective and battery life.

A Comparison of Predictive Spatial Augmented Reality Cues for Procedural Tasks

Previous research has demonstrated that Augmented Reality can reduce a user's task response time and mental effort when completing a procedural task. This paper investigates techniques to improve user performance and reduce mental effort by providing projector-based Spatial Augmented Reality predictive cues for future responses. The objective of the two experiments conducted in this study was to isolate the performance and mental effort differences from several different annotation cueing techniques for simple (Experiment 1) and complex (Experiment 2) button-pressing tasks. Comporting with existing cognitive neuroscience literature on prediction, attentional orienting, and interference, we hypothesized that for both simple procedural tasks and complex search-based tasks, having a visual cue guiding to the next task's location would positively impact performance relative to a baseline, no-cue condition. Additionally, we predicted that direction-based cues would provide a more significant positive impact than target-based cues. The results indicated that providing a line to the next task was the most effective technique for improving the users' task time and mental effort in both the simple and complex tasks.

Mixed Reality with HoloLens: Where Virtual Reality Meets Augmented Reality in the Operating Room

Virtual reality and augmented reality devices have recently been described in the surgical literature. The authors have previously explored various iterations of these devices, and although they show promise, it has become clear that virtual reality and/or augmented reality devices alone do not adequately meet the demands of surgeons. The solution may lie in a hybrid technology known as mixed reality, which merges many virtual reality and augmented realty features. Microsoft's HoloLens, the first commercially available mixed reality device, provides surgeons intraoperative hands-free access to complex data, the real environment, and bidirectional communication. This report describes the use of HoloLens in the operating room to improve decision-making and surgical workflow. The pace of mixed reality-related technological development will undoubtedly be rapid in the coming years, and plastic surgeons are ideally suited to both lead and benefit from this advance.

Using Google Glass in Nonsurgical Medical Settings: Systematic Review

Background

Wearable technologies provide users hands-free access to computer functions and are becoming increasingly popular on both the consumer market and in various industries. The medical industry has pioneered research and implementation of head-mounted wearable devices, such as Google Glass. Most of this research has focused on surgical interventions; however, other medical fields have begun to explore the potential of this technology to support both patients and clinicians.

Objective

Our aim was to systematically evaluate the feasibility, usability, and acceptability of using Google Glass in nonsurgical medical settings and to determine the benefits, limitations, and future directions of its application.

Methods

This review covers literature published between January 2013 and May 2017. Searches included PubMed MEDLINE, Embase, INSPEC (Ebsco), Cochrane Central Register of Controlled Trials (CENTRAL), IEEE Explore, Web of Science, Scopus, and Compendex. The search strategy sought all articles on Google Glass. Two reviewers independently screened titles and abstracts, assessed full-text articles, and extracted data from articles that met all predefined criteria. Any disagreements were resolved by discussion or consultation by the senior author. Included studies were original research articles that evaluated the feasibility, usability, or acceptability of Google Glass in nonsurgical medical settings. The preferred reporting results of systematic reviews and meta-analyses (PRISMA) guidelines were followed for reporting of results.

Results

Of the 852 records examined, 51 met all predefined criteria, including patient-centered (n=21) and clinician-centered studies (n=30). Patient-centered studies explored the utility of Google Glass in supporting patients with motor impairments (n=8), visual impairments (n=5), developmental and psychiatric disorders (n=2), weight management concerns (n=3), allergies (n=1), or other health concerns (n=2). Clinician-centered studies explored the utility of Google Glass in student training (n=9), disaster relief (n=4), diagnostics (n=2), nursing (n=1), autopsy and postmortem examination (n=1), wound care (n=1), behavioral sciences (n=1), and various medical subspecialties, including, cardiology (n=3), radiology (n=3), neurology (n=1), anesthesiology (n=1), pulmonology (n=1), toxicology (n=1), and dermatology (n=1). Most of the studies were conducted in the United States (40/51, 78%), did not report specific age information for participants (38/51, 75%), had sample size <30 participants (29/51, 57%), and were pilot or feasibility studies (31/51, 61%). Most patient-centered studies (19/21, 90%) demonstrated feasibility with high satisfaction and acceptability among participants, despite a few technical challenges with the device. A number of clinician-centered studies (11/30, 37%) reported low to moderate satisfaction among participants, with the most promising results being in the area of student training. Studies varied in sample size, approach for implementation of Google Glass, and outcomes assessment.

Conclusions

The use of Google Glass in nonsurgical medical settings varied. More promising results regarding the feasibility, usability, and acceptability of using Google Glass were seen in patient-centered studies and student training settings. Further research evaluating the efficacy and cost-effectiveness of Google Glass as an intervention to improve important clinical outcomes is warranted.

Additional Visualization via Smart Glasses Improves Accuracy of Wire Insertion in Fracture Surgery

BACKGROUND

Smart glasses (SG) are a wearable device consisting of a small computer built into a head-mounted monitor (HMM) that can display various kinds of information. Lateral side visualization is displayed on the HMM of SG so the operator may also see it and the anteroposterior (AP) direction simultaneously. The present pilot study aimed to investigate the usefulness of SG in wire insertion for bone fracture.

METHODS

We marked both the front and lateral sides of the shaft of an artificial femur bone. From the tip of the greater trochanter, we inserted a 2.4-mm Kirschner wire (K-wire) so that it could be directed toward the marks in both planes. Three surgeons enrolled in the study each performed 10 trials, both with SG (SG arm) and without (direct vision arm). We defined the error angle as the angle between the K-wire and the line connecting the marking point from the insertion point in both the front and lateral view images. We also measured the time it took to insert the K-wire in both arms.

RESULTS

The SG had a significantly reduced (mean = 3.2°) error angle ( P = .02) when compared to the direct vision group (mean = 4.8°). However, no significant difference was found between direct vision (mean = 17.5 seconds) and SG arms (mean = 14.9 seconds) in the insertion time.

CONCLUSION

While keeping the AP image view in primary focus, simultaneously viewing the lateral side of the surgical field using SG helps achieve more accurate wire insertion in surgery.

Initial Assessment, Treatment, and Follow-Up of Minor Pediatric Burn Wounds in Four Patients Remotely: A Preliminary Communication

BACKGROUND

Close, multidisciplinary collaboration with burn experts is the essential strategy to achieve the best functional and esthetic outcomes in burn wound treatment. Management of minor burn injuries, where no specialized care is available, might be challenging. One concept to achieve a fast and timely result is the application of telemedicine. The objective of this study was to assess and develop a simple telemedicine protocol, which can be applied globally.

MATERIAL AND METHODS

We present a pilot study based on a pediatric population of four patients with minor burns. Based on the severity and burn area, two cases of ambulant pediatric patients (mean 1% total body surface area, superficial and deep 2° burn) with minor burn injuries met study criteria and were enrolled. A pediatrician performed the initial assessment, followed by plastic surgery video consultation, using telephone's digital camera. Treatment protocols were designed to optimize outcomes. After the initial treatment phase, which took place at a nonteaching local hospital in Poland from January 1, 2014, to December 31, 2014, clinical follow-up was performed by a plastic surgeon via smartphone in the United States.

RESULTS

We have achieved complete burn wound resolution, in all patients, with no scarring and only minor discoloration. A simple, reproducible treatment protocol was designed to include dressing changes and additional outpatient visits.

CONCLUSIONS

Implementation of a telemedicine protocol allows for easy access to burn consultations, helps multidisciplinary collaboration, eases follow-ups, and shortens specialists' consult wait times. Real-time evaluation provides fast and flexible treatment, without long distance travels, for patients and their families. Telemedicine increases the frequency of follow-up, contributes to the esthetic outcome, and together with improved cost-effectiveness is beneficial for both the patient and healthcare system.

Assessment of Google Glass as an adjunct in neurological surgery

Background:

We assess Google Glass (“Glass”) in improving postoperative review (“debriefing”) and augmenting education in Neurological Surgery at a tertiary academic medical center.

Methods:

This was a prospective study. Participants were patients of Neurological Surgery physicians at a Tertiary Care Level 1 Academic Trauma Center. Resident physicians received a pre-questionnaire immediately following surgery. Next, the resident and attending physicians debriefed by reviewing the Glass operative recording. Then, residents completed a 4-part post-questionnaire. Questions 1–3 assessed: (1) the residents’ comfort level with the procedure, (2) the quality of education provided by their superiors, and (3) their comfort level in repeating the operation. Question 4 assessed: (4) the perceived benefit of debriefing using Glass.

Results:

Twelve surveys were collected. Scores were based on a 5-point Likert scale, with a higher score corresponding to a more positive response. For Questions 1–3, the average pre- and post-questionnaire scores were 3.75 and 4.42, respectively (P <.05). For Question 4, the average post-questionnaire score was 4.63, suggesting that postoperative Glass review improved their technical understanding of the procedure.

Conclusions:

Glass significantly improved neurosurgery residents’ comfort level and quality of training, and provided a high fidelity, reliable, and modifiable tool that enhanced residents’ understanding, expertise, and educational experience. Of note, certain limitations such as variable battery life, variable image quality, and subpar compatibility with surgeon loupes must still be overcome for Glass to become a realistic addition to neurosurgical education.

Augmented reality assisted surgery: a urologic training tool

Augmented reality is widely used in aeronautics and is a developing concept within surgery. In this pilot study, we developed an application for use on Google Glass^® optical head-mounted display to train urology residents in how to place an inflatable penile prosthesis. We use the phrase Augmented Reality Assisted Surgery to describe this novel application of augmented reality in the setting of surgery. The application demonstrates the steps of the surgical procedure of inflatable penile prosthesis placement. It also contains software that allows for detection of interest points using a camera feed from the optical head-mounted display to enable faculty to interact with residents during placement of the penile prosthesis. Urology trainees and faculty who volunteered to take part in the study were given time to experience the technology in the operative or perioperative setting and asked to complete a feedback survey. From 30 total participants using a 10-point scale, educational usefulness was rated 8.6, ease of navigation was rated 7.6, likelihood to use was rated 7.4, and distraction in operating room was rated 4.9. When stratified between trainees and faculty, trainees found the technology more educationally useful, and less distracting. Overall, 81% of the participants want this technology in their residency program, and 93% see this technology in the operating room in the future. Further development of this technology is warranted before full release, and further studies are necessary to better characterize the effectiveness of Augmented Reality Assisted Surgery in urologic surgical training.

Feasibility Study of Utilization of Action Camera, GoPro Hero 4, Google Glass, and Panasonic HX-A100 in Spine Surgery

STUDY DESIGN

Study for feasibility of commercially available action cameras in recording video of spine.

OBJECTIVE

Recent innovation of the wearable action camera with high-definition video recording enables surgeons to use camera in the operation at ease without high costs. The purpose of this study is to compare the feasibility, safety, and efficacy of commercially available action cameras in recording video of spine surgery.

SUMMARY OF BACKGROUND DATA

There are early reports of medical professionals using Google Glass throughout the hospital, Panasonic HX-A100 action camera, and GoPro. This study is the first report for spine surgery.

METHODS

Three commercially available cameras were tested: GoPro Hero 4 Silver, Google Glass, and Panasonic HX-A100 action camera. Typical spine surgery was selected for video recording; posterior lumbar laminectomy and fusion. Three cameras were used by one surgeon and video was recorded throughout the operation. The comparison was made on the perspective of human factor, specification, and video quality.

RESULTS

The most convenient and lightweight device for wearing and holding throughout the long operation time was Google Glass. The image quality; all devices except Google Glass supported HD format and GoPro has unique 2.7K or 4K resolution. Quality of video resolution was best in GoPro. Field of view, GoPro can adjust point of interest, field of view according to the surgery. Narrow FOV option was the best for recording in GoPro to share the video clip. Google Glass has potentials by using application programs. Connectivity such as Wi-Fi and Bluetooth enables video streaming for audience, but only Google Glass has two-way communication feature in device.

CONCLUSION

Action cameras have the potential to improve patient safety, operator comfort, and procedure efficiency in the field of spinal surgery and broadcasting a surgery with development of the device and applied program in the future.

The Use of Smart Glasses for Surgical Video Streaming

Observation of surgical procedures performed by experts is extremely important for acquisition and improvement of surgical skills. Smart glasses are small computers, which comprise a head-mounted monitor and video camera, and can be connected to the internet. They can be used for remote observation of surgeries by video streaming. Although Google Glass is the most commonly used smart glasses for medical purposes, it is still unavailable commercially and has some limitations. This article reports the use of a different type of smart glasses, InfoLinker, for surgical video streaming. InfoLinker has been commercially available in Japan for industrial purposes for more than 2 years. It is connected to a video server via wireless internet directly, and streaming video can be seen anywhere an internet connection is available. We have attempted live video streaming of knee arthroplasty operations that were viewed at several different locations, including foreign countries, on a common web browser. Although the quality of video images depended on the resolution and dynamic range of the video camera, speed of internet connection, and the wearer's attention to minimize image shaking, video streaming could be easily performed throughout the procedure. The wearer could confirm the quality of the video as the video was being shot by the head-mounted display. The time and cost for observation of surgical procedures can be reduced by InfoLinker, and further improvement of hardware as well as the wearer's video shooting technique is expected. We believe that this can be used in other medical settings.

Evaluation of Google Glass Technical Limitations on Their Integration in Medical Systems

Google Glass is a wearable sensor presented to facilitate access to information and assist while performing complex tasks. Despite the withdrawal of Google in supporting the product, today there are multiple applications and much research analyzing the potential impact of this technology in different fields of medicine. Google Glass satisfies the need of managing and having rapid access to real-time information in different health care scenarios. Among the most common applications are access to electronic medical records, display monitorizations, decision support and remote consultation in specialties ranging from ophthalmology to surgery and teaching. The device enables a user-friendly hands-free interaction with remote health information systems and broadcasting medical interventions and consultations from a first-person point of view. However, scientific evidence highlights important technical limitations in its use and integration, such as failure in connectivity, poor reception of images and automatic restart of the device. This article presents a technical study on the aforementioned limitations (specifically on the latency, reliability and performance) on two standard communication schemes in order to categorize and identify the sources of the problems. Results have allowed us to obtain a basis to define requirements for medical applications to prevent network, computational and processing failures associated with the use of Google Glass.

Feasibility and safety of augmented reality-assisted urological surgery using smartglass

PURPOSE

To assess the feasibility, safety and usefulness of augmented reality-assisted urological surgery using smartglass (SG).

METHODS

Seven urological surgeons (3 board urologists and 4 urology residents) performed augmented reality-assisted urological surgery using SG for 10 different types of operations and a total of 31 urological operations. Feasibility was assessed using technical metadata (number of photographs taken/number of videos recorded/video time recorded) and structured interviews with the urologists on their use of SG. Safety was evaluated by recording complications and grading according to the Clavien-Dindo classification. Usefulness of SG for urological surgery was queried in structured interviews and in a survey.

RESULTS

The implementation of SG use during urological surgery was feasible with no intrinsic (technical defect) or extrinsic (inability to control the SG function) obstacles being observed. SG use was safe as no grade 3-5 complications occurred for the series of 31 urological surgeries of different complexities. Technical applications of SG included taking photographs/recording videos for teaching and documentation, hands-free teleconsultation, reviewing patients' medical records and images and searching the internet for health information. Overall usefulness of SG for urological surgery was rated as very high by 43 % and high by 29 % of surgeons.

CONCLUSIONS

Augmented reality-assisted urological surgery using SG is both feasible and safe and also provides several useful functions for urological surgeons. Further developments and investigations are required in the near future to harvest the great potential of this exciting technology for urological surgery.

A telemedicine wound care model using 4G with smart phones or smart glasses: A pilot study

To assess the feasibility of a wound care model using 4th-generation mobile communication technology standards (4G) with smart phones or smart glasses for wound management.This wound care model is an interactive, real-time platform for implementing telemedicine changing wound dressings, or doing operations. It was set up in March 2015 between Jinhua in Zhejiang province and Shanghai, China, which are 328 km apart. It comprised of a video application (APP), 4G net, smart phones or smart glasses, and a central server.This model service has been used in 30 patients with wounds on their lower extremities for 109 times in 1 month. Following a short learning curve, the service worked well and was deemed to be user-friendly. Two (6.7%) patients had wounds healed, while others still required wound dressing changes after the study finished. Both local surgeons and patients showed good acceptance of this model (100% and 83.33%, respectively).This telemedicine model is feasible and valuable because it provides an opportunity of medical service about wound healing in remote areas where specialists are scarce.

Surgical Vision

Google Glass is, in essence, a smartphone in the form of a pair of spectacles. It has a display system, a bone conduction “speaker,” video camera, and connectivity via WiFi or Bluetooth technologies. It can also be controlled by voice command. Seizing Google Glass’ capabilities as windows of opportunity, surgeons have been the first group of doctors trying to incorporate the technology into their daily practices. Experiences from different groups have demonstrated Google Glass’ potential in improving perioperative care, intraoperative communication and documentation, surgical outcome as well as surgical training. On the other hand, the device has technical limitations, notably suboptimal image qualities and a short battery life. Its operational functions also bring forth concerns on the protection of patient privacy. Nonetheless, the technological advances that this device embodies hold promises in surgical innovations. Further studies are required, and surgeons should explore, investigate, and embrace similar technologies with keen and informed anticipation.

Patient monitoring with Google Glass: a pilot study of a novel monitoring technology

BACKGROUND

Head-mounted devices (HMDs) are of significant interest for applications within medicine, including in anesthesia for patient monitoring. Previous devices trialed in anesthesia for this purpose were often bulky, involved cable tethers, or were otherwise ergonomically infeasible. Google Glass is a modern HMD that is lightweight and solves many of the issues identified with previous HMDs.

AIM

To examine the acceptance of Google Glass as a patient monitoring device in a pediatric anesthesia context at Princess Margaret Hospital for Children, Perth, Australia.

METHODS

We developed a custom-designed software solution for integrating Google Glass into the anesthesia environment, which enabled the device user to continuously view patient monitoring parameters transmitted wirelessly from the anesthesia workstation.

RESULTS

A total of 40 anesthetists were included in the study. Each anesthetist used the device for the duration of a theater list. We found 90% of anesthetists trialing the device agreed that it was comfortable to wear, 86% agreed the device was easy to read, and 82.5% agreed the device was not distracting. In 75% of cases, anesthetists reported unprompted that they were comfortable using the device in theater. Anesthetists reported that they would use the device again in 76% of cases, and indicated that they would recommend the device to a colleague in 58% of cases.

CONCLUSION

Given the pilot nature of this study, we consider these results highly favorable. Anesthetists readily accepted Google Glass in the anesthetic environment, with further enhancements to device software, rather than hardware, now being the barrier to adoption. There are a number of applications for HMDs in pediatric anesthesia.
