Mobile Stroke: An Experience of Intravenous Thrombolysis Guided by Teleconsultation Based on Google Glass

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.

Use of Wearable Technology in Remote Evaluation of Acute Stroke Patients: Feasibility and Reliability of a Google Glass-Based Device

BACKGROUND

Telestroke is an efficient, cost-effective way to standardize care and improve access to immediate neurologic expertise for rural hospitals and other underserved areas. Hands-free wearable technology potentially allows for faster evaluations that fit easily within prehospital workflows and could improve prehospital triage of stroke patients to appropriate receiving stroke centers. The goal of this study is to assess the feasibility and inter-rater reliability of wearable eyeglass video technology in assessing stroke-related neurologic deficits in patients with suspected acute stroke.

METHODS

Consecutive patients with suspected stroke were evaluated concurrently by an on-site neurologist using wearable eyeglass video technology and a remotely located neurologist viewing the patient through an online platform. Inter-rater reliability in assigning National Institutes of Health Stroke Scale (NIHSS) scores was evaluated using inter-rater correlation coefficient (ICC) and weighted kappa scores.

RESULTS

Among 17 enrolled patients, mean age was 58 (SD ± 20) and 29% were female. There was a high degree of correlation in total NIHSS score (ICC .99 and weighted kappa .88) and across all NIHSS subitems (ICC .81-1 and weighted kappa .68-1) between the examiner evaluating remotely via wearable eyeglass video technology with access to the patient and the in-person examiner. The maximum difference between the 2 NIHSS scores was 3.

CONCLUSIONS

The use of wearable eyeglass video technology in telestroke is feasible and reliable. Use of this technology in the prehospital setting has the potential to improve early assessment of patients with acute stroke symptoms and to facilitate transfer to appropriate stroke centers in the regional systems of care.

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.

The progress of telestroke in China

Stroke remains the leading cause of death in China. The disparity of distribution in specialists and hospitals affects access to timely stroke care. Telestroke, the use of telemedicine for stroke, may be the solution to access to stroke care. Telestroke can improve the rate of successful intravenous thrombolysis and shorten the time to treatment. Here we review the progress of telestroke in China.
