Caesarean sections before and during the COVID-19 pandemic in western Sydney, Australia
To determine the changes in emergency and elective caesarean section (CS) rates since the COVID-19 pandemic, identify the groups most affected, and examine changes in the factors associated with CS rates, and reasons for CS. We conducted a retrospective cohort study using routinely collected data of 22,346 births from before the pandemic (January 2018-February 2020) and 18,597 births during the pandemic (March 2020-December 2021). Data were analysed using multinominal logistic regression. The CS rate increased by 4.1% (from 30.1% to 34.2%), reflecting increases of 2.3% in emergency CS (from 11.5% to 13.8%) and 1.7% in elective CS (from 18.7% to 20.4%). Large groups with notable increases were women who were nulliparous (7.2% increase), from South Asia (6.0%), obese (5.2%) and giving birth at a small hospital (6.1%). Compared to pre-pandemic, the relative risk of an emergency CS versus a vaginal delivery increased 1.36 times (adjusted relative risk ratio (aRRR) = 1.36; 95% CI = 1.27, 1.45) and the risk of having an elective CS increased 1.11 times (aRRR = 1.11; 95% CI = 1.04, 1.20). Factors associated with both emergency and elective CS were age, region of birth, reproductive history, body mass index, hypertension, diabetes, mode of antenatal care and hospital. Socio-Economic Indexes for Areas and antenatal care were only associated with elective CS. Baby gender was only associated with emergency CS. Preterm gestation at delivery was associated with reduced emergency but increased elective CS. Foetal compromise was the most common indication for emergency CS (43.2%) and increased the most (8.0%). Previous CS was the most common indication for elective CS (61.5%) and reduced the most (1.9%). Both emergency and elective CS rates increased significantly during the pandemic, with the former increasing at a higher rate. The persistent upward trend of CS rates, exacerbated by increasing proportions of nulliparous women undergoing CSs, is concerning.

Protecting workers' well-being in times of crisis: the first wave of COVID-19 in an Australian healthcare setting in 2020
The COVID-19 pandemic continues to challenge healthcare systems worldwide. The authors examined the lived experiences and perceptions of healthcare workers (HCWs) in managerial and senior positions to explore the pandemic's effects on well-being and valued organisational responses. Using purposive sampling, the authors conducted 39 semi-structured interviews with senior staff including health service administrators, heads of department and senior clinicians at a designated COVID-19 facility in New South Wales, Australia. Interviews were conducted from November 2020 to February 2021 to reflect on experiences during the height of the pandemic in 2020 (mid-March to the end of May 2020). Workplace experiences affecting HCWs' well-being included being shunned by others, fear of infecting family, fear of the unknown, concerns about personal protective equipment, lack of direction from above and increased workload. Organisational interventions to protect the health and safety of HCWs and their patients included redeployment, improved communication, effective management committees, education and mental health supports. Organisations can minimise worker-identified factors threatening their well-being during a health crisis by applying broad-ranging initiatives including inclusive and open communication, promoting flexible work practices, providing up-to-date guidelines and policies and fostering camaraderie between workers. The voices of senior clinical and managerial staff have been largely unheard during the COVID-19 pandemic. The authors addressed this deficit by describing their experiences and insights regarding the pandemic's impact on well-being and the organisation's responses to simultaneously safeguarding its staff and providing quality patient care.

Managing COVID-19 in an Australian designated isolation facility: Implications for current and future healthcare crises based on in-depth interviews
Health care workers’ (HCWs) lived experiences and perceptions of the pandemic can prove to be a valuable resource in the face of a seemingly persistent Novel coronavirus disease 2019 (COVID-19)–to inform ongoing efforts, as well as identify components essential to a crisis preparedness plan and the issues pertinent to supporting relevant, immediate change. We employed a phenomenological approach and, using purposive sampling, conducted 39 semi-structured interviews with senior healthcare professionals who were employed at a designated COVID-19 facility in New South Wales (NSW), Australia during the height of the pandemic in 2020. Participants comprised administrators, heads of department and senior clinicians. We obtained these HCWs’ (i) perspectives of their lived experience on what was done well and what could have been done differently and (ii) recommendations on actions for current and future crisis response. Four themes emerged: minimise the spread of disease at all times; maintain a sense of collegiality and informed decision-making; plan for future crises; and promote corporate and clinical agility. These themes encapsulated respondents’ insights that should inform our capacity to meet current needs, direct meaningful and in situ change, and prepare us for future crises. Respondents’ observations and recommendations are informative for decision-makers tasked with mobilising an efficacious approach to the next health crisis and, in the interim, would aid the governance of a more robust workforce to effect high quality patient care in a safe environment.

Using the Experiences and Perceptions of Health Care Workers to Improve the Health Care Response to the COVID-19 Pandemic
Background: We sought the opinions of health care workers (HCWs) at a designated COVID-19 facility receiving the first cases to identify workplace modifications and inform effective changes to maximize health and safety at the onset of a crisis. Methods: A cross-sectional study utilized open- and close-ended questions gathered demographic and work details, experiences and perspectives on infection control, communication, support, and the workplace. Qualitative data were analyzed thematically and quantitative were analyzed using descriptive statistics. Findings: Of 340 HCWs, most approved of the organization’s response to minimizing risk (81.0%), infection control training (81.1%), and supplies (74.3%). Key actions included up-to-date guidelines (93.6%) and specialized infectious diseases clinics (94.9%). Conclusions: HCWs rated the organization’s adaptive changes highly, noting areas for improvement such as transparency and timeliness of communication. Incorporating input from HCWs when responding to health crises was beneficial to maximize staff health and safety and consequently that of patients.

Detrimental changes to the health and well-being of healthcare workers in an Australian COVID-19 hospital
Background: Most studies examining the psychological impact of COVID-19 on healthcare workers (HCWs) have assessed well-being during the initial stages or the peak of the first wave of the pandemic. We aimed to measure the impact of COVID-19 and potential changes over time in its impact, on the health and well-being of HCWs in an Australian COVID-19 hospital. Methods: An online questionnaire assessed current and retrospective physical and mental health; psychological distress (Kessler Psychological Distress Scale); lifestyle behaviours; and demographics, providing measures of health and wellbeing at three phases of the pandemic. Targeted staff were invited to participate via email and in-person. Additional promotional activities were directed to all staff. Changes in general health, mental health and psychological distress were examined using McNemar’s Chi-square. Associations between other categorical variables were tested using Chi-Square or non-parametric equivalents as appropriate. Logistic regression explored risk factors for current distress. Results: Four hundred thirty-three eligible HCWs answered all (74 %) or part of the questionnaire. Current self-rated health and mental health were significantly better than during the height of the pandemic, but had not returned to pre-pandemic levels. Psychological distress was significantly more common during the height of the pandemic (34.2 %) than currently (22.4 %), and during the height of the pandemic distress was significantly more common among younger than older HCWs. Females were significantly more likely to be distressed that males currently, but not during the height of the pandemic. High distress during the height of the pandemic was more likely to be maintained by HCWs who were less physically active than usual during the height of the pandemic (OR = 5.5); had low self-rated mental health before the pandemic (OR = 4.8); and who had 10 or more years of professional experience (OR = 3.9). Conclusions: The adverse effects of the pandemic on HCWs have lessened with the easing of pandemic demands, but health and well-being have not reverted to pre-pandemic levels. This indicates continued exposure to elevated levels of stress and/or a sustained effect of earlier exposure. Initiatives that provide ongoing support beyond the pandemic are needed to ensure that HCWs remain physically and mentally healthy and are able to continue their invaluable work.
