Sleep disturbance affects Covid-19 medics

Almost 40% of paediatric healthcare workers in Wuhan experienced sleep disturbance during the Covid-19 pandemic and 25% reported symptoms of anxiety and depression, according to this survey-based study. Sleep disturbance was independently associated with being an only child, exposure to Covid-19 patients and depression. The authors call for more mental health services for frontline healthcare workers managing the outbreak.

Work quality and emotional exhaustion

Social integration at work, and the social relevance of work, can mitigate the impact of emotional exhaustion amongst nurses, according to this study of 432 Malaysian nurses. Other factors reducing the impact of emotional exhaustion included the way in which work is organised and the operation of effective safe and healthy working conditions, the authors find. They conclude that “by addressing the emotional exhaustion issue among the nursing staff, their work responsibilities and work performance can be enhanced.”

Covid-19 disinfection chambers: are they safe?

Human disinfection chambers are an example of how medical practice is rapidly innovating in response to the global burden of Covid-19. Most chambers being used in healthcare settings to disinfect healthcare staff have an entry and exit point, an enclosed chamber where the disinfection takes place, a solvent supply, chemical chamber, air supply and mixer. This article looks at the effectiveness, health hazards and safety aspects of disinfection chambers, particularly as the main routes of potential exposure are inhalation and absorption. It concludes: “When two or more chemicals are compounded together, the properties of the compound cannot be assumed to carry the same risk category as the individual chemicals. Assuming that a safe chemical plus safe chemical makes a safe compound is a dangerous assumption.” The authors add that changing the chemical’s formulation and route of administration may drastically affect its safety profile. A chemical may be safe when applied topically in liquid form, but extremely toxic when atomized and inhaled.

Carpal tunnel rehabilitation

Most patients with carpal tunnel syndrome (CTS) can return to work within a year of carpal tunnel decompression treatment, according to this occupational analysis of patients between 2014 and 2017. However, manual workers and patients with poorer pre-operative hand function have poorer return-to-work outcomes, the study suggests. Median return-to-work time amongst the 469 patients was four weeks after surgery; however, 15% of those undertaking manual labour were unable to return (compared with 5% of the total sample).

HPV and surgical smoke

Surgical smoke generated during the treatment of patients for HPV-related lesions should be treated as potentially infectious, according to this systematic review of 21 articles. The research literature demonstrates that surgical smoke can contain HPV-related DNA, and that this can contaminate the upper airways of operating theatre staff. Whether this corresponds to infectious virus is unknown, and there is no evidence showing an increased prevalence of HPV infection or disease in OT staff following exposure. The authors conclude, however, that “it would be safest to treat surgical smoke as potentially infectious”, advising that precautions should include local exhaust ventilation, general room ventilation and full PPE including fit-tested respirator use at a minimum of N95 grade.

Working from home: preserving occupational health

Employers have a duty to preserve the health of employees required to telework as a result of Covid-19, according to this postscript published in Occupational & Environmental Health. The authors argue that the current increase in home working has occurred in an anxiety-provoking context linked to the pandemic, which is likely to worsen telework-associated psychological and behavioural risks, “especially those associated with addictions”. Those with pre-existing mental health problems may face particular issues arising from isolation, so that taken together, “the covid-19 pandemic may exacerbate occupational hazards beyond the more obvious examples of healthcare settings or other jobs on the front line.”

Physical work and life expectancy

High physical work demands are a risk factor for a shortened working life and increased years of sickness absence and unemployment, according to this Danish study. Individuals with physical work had a significantly lower working life expectancy than those with low physical work demands. This is particularly the case for women. At age 30, women with high physical work demands can expect 3.1 years less working life, 11 months more sickness absence and 16 months more unemployment than low-exposed women. For men, the comparable differentials were two years, 12 months and eight months respectively. The authors conclude their results are important in the context of expanding the knowledge base for informed political decision-making concerning statutory retirement age.

Workplace yoga can be “convenient and low-cost” intervention

A group mindfulness-based yoga course may be a convenient and low-cost approach to support the health and wellbeing of healthcare workers, according to this study of 43 healthcare professionals. The study investigates if an eight-week intervention can help manage burnout amongst the group, concluding that at post-intervention follow-up members of the group had significantly better scores on personal accomplishment, depression, stress and anxiety, perceived resilience and compassion. They also had a positive perception of the intervention itself.
