The majority of research investigating healthcare workers’ (HCWs) willingness to work during public health emergencies, asks participants to forecast their perceptions based on hypothetical emergencies, rather than in response to the actual public health emergencies they have experienced. This research explored frontline HCWs willingness to work during Australia’s first wave of the COVID-19 pandemic among frontline HCWs.

Participants (n = 580) completed an online questionnaire regarding their willingness to work during the pandemic.

A total of 42% of participants reported being less willing to work during the pandemic compared to before. Availability of personal protective equipment (PPE), concern expressed by family members, and viral exposure were significant barriers. A third of participants disagreed that some level of occupational risk for exposure to infectious disease was acceptable while a quarter of participants had received communications from their workplace concerning obligations to work during COVID-19.

The COVID-19 pandemic has impacted Australian frontline HCWs’ willingness to work. Scarcity of PPE and exposure to the virus were the most cited reasons impacting on willingness to work. Appropriate policies and practices should be implemented and communicated efficiently to frontline HCW’s. This research provides insight into the lived experiences of Australian healthcare professionals’ willingness to work during a pandemic.

Coronavirus disease 2019 personal protective equipment has been reported to affect communication in healthcare settings. This study sought to identify those challenges experimentally.

Bamford–Kowal–Bench speech discrimination in noise performance of healthcare workers was tested under simulated background noise conditions from a variety of hospital environments. Candidates were assessed for ability to interpret speech with and without personal protective equipment, with both normal speech and raised voice.

There was a significant difference in speech discrimination scores between normal and personal protective equipment wearing subjects in operating theatre simulated background noise levels (70 dB).

Wearing personal protective equipment can impact communication in healthcare environments. Efforts should be made to remind staff about this burden and to seek alternative communication paradigms, particularly in operating theatre environments.

Chitosan (CS) is currently used as a hemostatic agent in emergencies and in military settings. However, its application is limited owing to its poor hydrophilia at neutral pH. Carboxymethyl chitosan (CMCS) is an important, water-soluble derivative of CS. In this study, we prepared CS and CMCS microspheres (CSMs and CMCSMs, respectively) and evaluated their hemostatic effect.

To prepare the microspheres of various sizes, we used the emulsion cross-linking technique. CMCSMs were also loaded with etamsylate (DIC). Clotting time in vitro and in a hepatic injury model was examined to evaluate the hemostatic effect.

CMCSMs swelled more and clotted faster than did CSMs. CMCSMs loaded with DIC had no effect on hemostasis.

Both increasing material hydrophilicity and expanding the contact area promoted clotting, whereas chemical cross-linking hampered it because of decreased swelling. CMCSMs are promising candidates for the production of effective hemostatic agents. (Disaster Med Public Health Preparedness. 2017;11:660–667)
