Closing The Gap

AbstractDue to extreme shortages of personal protective equipment caused by the COVID-19 pandemic, many healthcare workers will be forced to recycle protective masks intended for disposal after a single use. We propose investigating the use of ultraviolet germicidal irradiation to sterilize masks of SARS-CoV-2 for safer reuse.

N95 Respirators

The unprecedented pandemic of SARS-CoV-2 has created worldwide shortages of personal protective equipment, in particular respiratory protection such as N95 respirators. SARS-CoV-2 transmission is frequently occurring in hospital settings, with numerous reported cases of nosocomial transmission highlighting the vulnerability of healthcare workers. In general, N95 respirators are designed for single use prior to disposal. Here, we have analyzed four readily available and often used decontamination methods: UV, 70% ethanol, 70C heat and vaporized hydrogen peroxide for inactivation of SARS-CoV-2 on N95 respirators. Equally important we assessed the function of the N95 respirators after multiple wear and decontamination sessions.

The COVID-19 pandemic has led to global shortages of personal protective equipment (PPE). Healthcare workers (HCW) have comprised a significant proportion of COVID-19 cases in many countries. The PPE-SAFE survey was conducted to study current practices, availability, shortages, training and confidence in PPE amongst intensive care HCWs around the world. Herein, we describe the results of the Australian respondents to the PPE-SAFE survey. 29% of respondents reported that at least one item of usually available PPE was missing, and 12% reported reuse of single-use items. Only 40% felt that the PPE available to them offered adequate protection. Fit-testing of respirators had never been performed for 47% of respondents, and 49% reported at least one adverse effect from the use of PPE.

The unprecedented pandemic of SARS-CoV-2 has created worldwide shortages of personal protective equipment, in particular respiratory protection such as N95 respirators. SARS-CoV-2 transmission is frequently occurring in hospital settings, with numerous reported cases of nosocomial transmission highlighting the vulnerability of healthcare workers. In general, N95 respirators are designed for single use prior to disposal. Several groups have addressed the potential for re-use of N95 respirators from a mechanical or from a decontamination perspective. Here, we analyzed four different decontamination methods – UV radiation (260 – 285 nm), 70ºC heat, 70% ethanol and vaporized hydrogen peroxide (VHP) – for their ability to reduce contamination with infectious SARS-CoV-2 and their effect on N95 respirator function.

Novel Coronavirus

As the global spread of novel coronavirus (SARS-CoV-2) escalates, the high demand for personal protective equipment (PPE) has created shortages of this equipment globally and prompted the need to ensure appropriate stewardship and develop strategies to conserve supply. Surgical masks have broad and commonplace applications as PPE, including in the care of suspected or confirmed COVID-19 patients, and for the care of the general patient population in areas where community spread of COVID-19 is of concern. Surgical mask rationing and conservation is therefore a priority to ensure adequate supply during a pandemic. Several methods have been considered to decontaminate and allow the reuse of single-use PPE, such as hydrogen peroxide vapour and ultraviolet germicidal irradiation, but to date this literature has not been comprehensively synthesized. The objective of this systematic review is to identify and synthesize data from published studies evaluating interventions used to decontaminate or treat surgical mask PPE for the purposes of reuse.

Healthcare Workers (HCWs) and public health professionals are playing a pivotal role in containing COVID-19. Personal Protective Equipment (PPEs) are a critical component in the hierarchy of primary infection controls to ‘break the chain of infection’ to protect patients, HCW’s, and public. As SARS-CoV-2 is highly contagious, and vaccine and prophylactics not yet available, understanding correct PPE usage is imperative. This study aims to: understand purpose, use, and quality standards of body-coveralls and gowns and how to use PPE’s for effective protection in COVID 19 in India. Types of PPE’s in healthcare, their purposes, materials used, and properties were reviewed. Gowns and Body-coveralls classification and standards in Europe, USA and India were studied.  While current stipulated test standards for coveralls in India are lower, as routine use of reusable gowns made of woven fabrics is more common in India, one could hypothesize that these coveralls provide a higher level of protection. As per current understanding of mode(s) of transmission of SARS-CoV-2 a properly fitted N95 respirator; goggles and splash resistant face shield; gloves; and single-use full body-coverall/gown preferably resistant to Synthetic Blood Penetration under pressure and made of non-woven Laminated SMS (Spunbond-Meltblown-Spunbond)_or Non Laminated SSMMS fabrics are advisable depending upon anticipated level of exposure. HCW’s should educated about transmission risks, correct principles of infection control, functional purpose of PPE’s and must be conscious that PPE’s alone will not protect them.  They must follow good practices of how to wear (don) and how to remove (doff) and ensure that they do not inadvertently contaminate their clothing/skin and self-inoculate.

Second Wave

Frontline healthcare workers (HCWs) involved in the COVID-19 response have a higher risk of experiencing psychosocial distress amidst the pandemic. Between July and September 2020, a second wave of the COVID-19 pandemic appeared in Vietnam with Da Nang city being the epicenter. During the outbreak, HCWs were quarantined within the health facilities in a bid to limit the spread of COVID-19 to their respective communities. Using the stress component of the 21-item Depression, Anxiety and Stress Scale (DASS-21), we assessed the level of stress among HCWs in Da Nang city. Between 30 August and 15 September 2020, 746 frontline HCWs were recruited to fill in an online structured questionnaire. Overall, 44.6% of participants experienced increased stress and 18.9% severe or extremely severe stress. In multivariable analysis, increased stress was associated with longer working hours (OR = 1.012; 95% CI: 1.004–1.019), working in health facilities providing COVID-19 treatment (OR = 1.58, 95% CI: 1.04–2.39), having direct contact with patients or their bio-samples (physicians, nurses and laboratory workers; OR = 1.42, 95% CI: 1.02–1.99), low confidence in the available personal protective equipment (OR = 0.846; 95% CI: 0.744–0.962) and low knowledge on COVID-19 prevention and treatment (OR = 0.853; 95% CI: 0.739–0.986). In conclusion, many frontline HCWs experienced increased stress during the COVID-19 outbreak in Da Nang city. Reducing working time, providing essential personal protective equipment and enhancing the knowledge on COVID-19 will help to reduce this stress. Moreover, extra support is needed for HCWs who are directly exposed to COVID-19 patients.

New Strategies

In normal conditions, discarding single-use personal protective equipment after use is the rule for its users due to the possibility of being infected, particularly for masks and filtering facepiece respirators. When the demand for these protective tools is not satisfied by the companies supplying them, a scenario of shortages occurs, and new strategies must arise. One possible approach regards the disinfection of these pieces of equipment, but there are multiple methods. Analyzing these methods, Ultraviolet-C (UV-C) becomes an exciting option, given its germicidal capability. This paper aims to describe the state-of-the-art for UV-C sterilization in masks and filtering facepiece respirators. To achieve this goal, we adopted a systematic literature review in multiple databases added to a snowball method to make our sample as robust as possible and encompass a more significant number of studies. We found that UV-C’s germicidal capability is just as good as other sterilization methods. Combining this characteristic with other advantages makes UV-C sterilization desirable compared to other methods, despite its possible disadvantages.

ABSTRACT Objective: Bottlenecks in the personal protective equipment (PPE) supply chain have contributed to shortages of PPE during the COVID-19 pandemic, resulting in fractures in the functionality of healthcare systems. This study was conducted with the aim of determining the effectiveness of retrofitted commercial snorkel masks as an alternative respirator for healthcare workers during infectious disease outbreaks. Methods: A retrospective analysis was performed, analyzing qualitative and quantitative fit test results of the retrofitted Aria Ocean Reef® full-face snorkeling mask on healthcare workers at the McGill University Health Centre between April-June 2020. Historical fit test results, using medical-grade respirators, for healthcare workers were also analyzed. Results: During the study period, 71 participants volunteered for fit testing, 60.6% of which were nurses. The overall fit test passing rate using the snorkel mask was 83.1%. Of the participants who did not previously pass fit testing with medical-grade respirators, 80% achieved a passing fit test with the snorkel respirator. Conclusions: The results suggest that this novel respirator may be an effective and feasible alternative solution to address PPE shortages, while still providing healthcare workers with ample protection. Additional robust testing will be required to ensure that respirator fit is maintained, after numerous rounds of disinfection.

AbstractFacemasks are essential for healthcare workers but characteristics of the voice whilst wearing this personal protective equipment are not well understood. In the present study, we compared acoustic voice measures in recordings of sixteen adults producing standardised vocal tasks with and without wearing either a surgical mask or a KN95 mask. Data were analysed for mean spectral levels at 0–1 kHz and 1–8 kHz regions, an energy ratio between 0–1 and 1–8 kHz (LH1000), harmonics-to-noise ratio (HNR), smoothed cepstral peak prominence (CPPS), and vocal intensity. In connected speech there was significant attenuation of mean spectral level at 1–8 kHz region and there was no significant change in this measure at 0–1 kHz. Mean spectral levels of vowel did not change significantly in mask-wearing conditions. LH1000 for connected speech significantly increased whilst wearing either a surgical mask or KN95 mask but no significant change in this measure was found for vowel. HNR was higher in the mask-wearing conditions than the no-mask condition. CPPS and vocal intensity did not change in mask-wearing conditions. These findings implied an attenuation effects of wearing these types of masks on the voice spectra with surgical mask showing less impact than the KN95.
