Effectiveness of an anti-fog polymer coating in protective eyewear: a blinded, randomised controlled cross-over trial with healthcare providers in an emergency department setting

BackgroundEye protection is a mandatory component of the personal protective equipment in healthcare settings, especially for suspected or confirmed cases of COVID-19 and during aerosolising procedures. Fogging of protective eyewear is a frequent problem experienced by providers. The hydrophilic property of a sulfonated polymer, BiaXam, may be able to decrease fogging through wicking moisture from the lens. In this study, we tested the anti-fogging properties of this polymer when applied to protective eyewear. MethodsAn investigator-initiated prospective, randomised, single-blinded cross-over study was conducted in an emergency department in a large, tertiary care hospital. Participants were blinded and randomised first to either a pair of anti-fog coated or uncoated eyewear, and then to the alternative pair after 2 hours. Study participants completed an identical survey at the end of each 2-hour period. Results50 emergency medicine healthcare providers were enrolled and 48 completed the study. Results demonstrated a significant difference in fogging between the coated and uncoated eyewear, as 81% of the participants reported fogging of the uncoated lenses and only 55% of the participants reported fogging in the coated pair (p=0.0029). Participants reported that the uncoated lenses fogged two times as frequently on a 10-point Likert scale (4.5 +/- 3.3 vs 2.1 +/- 2.5;p<0.0001). Subgroup analysis of participants who wore only a surgical mask demonstrated even more efficacious results with coated eyewear. ConclusionOverall, sulfonated polymer-coated eyewear improved provider visualisation, user experience and perceived mitigation of potential medical errors.

Mobile app helps trainees manage emergencies at the bedside.

BACKGROUND: Although emergency departments (ED) have standardized guidelines for low-frequency, high-acuity diagnoses, they are not immediately accessible at the bedside, and this can cause anxiety in trainees and delay patient care. This problem is exacerbated during events like COVID-19 that require the rapid creation, iteration, and dissemination of new guidelines. METHODS: Physician innovators used design thinking principles to develop EM Protocols (EMP), a mobile application that clinicians can use to immediately view guidelines, contact consultants (e.g., cath lab activation), and access code-running tools. The project became an institutional high priority, because it helps EM trainees and off-service rotators manage low-frequency, high-acuity emergencies at the point of care, and its COVID-19 guidelines can be rapidly updated and disseminated in real time. RESULTS: This intervention was deployed across two academic medical centers during the COVID-19 surge. Nearly 300 ED clinicians have downloaded EMP, and they have interacted with the app over 5,400 times. It continues to be used regularly, over 12 months after the initial surge. Since the app was received positively, there are efforts to build in additional adult and pediatric guidelines. DISCUSSION: Digital health tools like EMP can serve as invaluable adjuncts for managing acute, life-threatening emergencies at the point of care. They can benefit trainees during normal day-to-day operations as well as scenarios that cause large-scale operational disruptions, such as natural disasters, mass casualty events, and future pandemics.

Home hospital as a disposition for older adults from the emergency department: Benefits and opportunities.

The $1 trillion industry of acute hospital care in the United States is shifting from inside the walls of the hospital to patient homes. To tackle the limitations of current hospital care in the United States, on November 25, 2020, the Center for Medicare & Medicaid Services announced that the acute hospital care at home waiver would reimburse for "home hospital" services. A "home hospital" is the home-based provision of acute services usually associated with the traditional inpatient hospital setting. Prior work suggests that home hospital care can reduce costs, maintain quality and safety, and improve patient experiences for select acutely ill adults who require hospital-level care. However, most emergency physicians are unfamiliar with the evidence of benefits demonstrated by home hospital services, especially for older adults. Therefore, the lead author solicited narrative inputs on this topic from selected experts in emergency medicine and home hospital services with clinical experience, publications, and funding on home hospital care. Then we sought to identify information most relevant to the practice of emergency medicine. We outline the proven and potential benefits of home hospital services specific to older adults compared to traditional acute care hospitalization with a focus on the emergency department.

Digital triage: Novel strategies for population health management in response to the COVID-19 pandemic.

The COVID-19 pandemic has created unique challenges for the U.S. healthcare system due to the staggering mismatch between healthcare system capacity and patient demand. The healthcare industry has been a relatively slow adopter of digital innovation due to the conventional belief that humans need to be at the center of healthcare delivery tasks. However, in the setting of the COVID-19 pandemic, artificial intelligence (AI) may be used to carry out specific tasks such as pre-hospital triage and enable clinicians to deliver care at scale. Recognizing that the majority of COVID-19 cases are mild and do not require hospitalization, Partners HealthCare (now Mass General Brigham) implemented a digitally-automated pre-hospital triage solution to direct patients to the appropriate care setting before they showed up at the emergency department and clinics, which would otherwise consume resources, expose other patients and staff to potential viral transmission, and further exacerbate supply-and-demand mismatching. Although the use of AI has been well-established in other industries to optimize supply and demand matching, the introduction of AI to perform tasks remotely that were traditionally performed in-person by clinical staff represents a significant milestone in healthcare operations strategy.
