Building a safety culture for infection prevention and control adherence at Howard Springs: A workplace survey.

BACKGROUND: Building a safety culture is essential to facilitate infection prevention and control (IPC) adherence in workplaces. We aimed to explore perceptions, barriers and facilitators to IPC procedures by the Australian Medical Assistance Team (AUSMAT) at Howard Springs International Quarantine Facility (HSIQF). METHODS: We performed a descriptive analysis of a cross-sectional survey administered to the AUSMAT employed at HSQIF from October 2020 to April 2021. We described motivation, training and compliance to IPC adherence and Likert scales described the level of agreement to the success of IPC procedures across the domains of communication, risk, trust, safety and environment, from the individual, team and organisational perspective. RESULTS: There were 101 participants (response rate 59%, 101/170) and 70% (71/101) were clinical. There was strong agreement to the success of IPC procedures, with a median 4 (agree) or 5 (strongly agree) across each domain and perspective of the 67 Likert items. Clinical staff reported slightly higher agreement than non-clinical staff across Likert items. To improve IPC compliance, most reported that daily training should be provided (77/97, 79%) and daily training was very or extremely effective (91/97, 93%). Participants were motivated by protecting self, friends, family and the community rather than workplace pressures. Barriers to IPC compliance were the ambient environment and fatigue. CONCLUSIONS: A safety culture was successfully built at HSQIF to optimise IPC adherence whilst managing multiple hazards including prevention of COVID-19 transmission. Strategies implemented by AUSMAT at the quarantine facility may inform the development of safety culture in other settings.

Rapid SARS-CoV-2 Seroprevalence Survey in Central and Western Divisions of Fiji, 2021.

During November-December 2021, we performed a SARS-CoV-2 seroprevalence survey in Central and Western Divisions of Fiji. A total of 539 participants 8-70 years of age were 95.5% (95% CI 93.4%-97.1%) seropositive, indicating high community levels of immunity. Seroprevalence studies can inform public health responses to emerging SARS-CoV-2 variants.

Electronic monitoring of doffing using video surveillance to minimise error rate and increase safety at Howard Springs International Quarantine Facility.

BACKGROUND: Safe donning and doffing of personal protective equipment (PPE) are critical to prevent transmission of infectious diseases. Novel strategies to improve infection prevention and control (IPC) adherence can optimise safety. We describe and quantify video surveillance of doffing at an outdoor hotel quarantine facility led by the Australian Medical Assistance Team in the Northern Territory, Australia. METHODS: Motion-activated video cameras were installed in seven areas where personnel doffed PPE upon exit from an area dedicated to quarantined residents. Video footage was reviewed daily and compliance issues were identified using a standardised checklist and risk graded to initiate feedback. We collated audit data from 1 February to 18 April 2021 to describe trends by month, staff group, doffing component and risk. RESULTS: In 235 h of video footage, 364 compliance issues were identified, of which none were considered high-risk compromising to PPE integrity. Compliance issues were low risk (55/364, 15%) or moderate risk (309/364, 85%) and the most common issue was missed or inadequate hand hygiene (156/364, 43%). Compliance issues per minute of video footage reviewed decreased following introduction of the activity, from 24 per 1000 in February to 7 per 1000 in March and April. CONCLUSION: Video surveillance with feedback supported rapid response to improve IPC adherence in a challenging ambient environment. The activity focused on perfection to identify compliance issues that would go unreported in most healthcare settings and contributed to a suit of activities that prevented any high-risk PPE breaches or compromises to safety.

An outdoor hotel quarantine facility model in Australia: best practice with optimal outcomes.

OBJECTIVE: To describe the operationalisation of a novel outdoor quarantine facility managed by the Australian Medical Assistance Team, the Howard Springs International Quarantine Facility (HSIQF) at the Centre for National Resilience in the Northern Territory, Australia. METHODS: We collated documentation and data from HSIQF to describe policies and procedures implemented and performed a descriptive analysis of key procedures and outcomes. RESULTS: From 23 October 2020 to 31 March 2021, 2.2% (129/5,987) of residents were confirmed COVD-19 cases. On average per day, 82 [Interquartile Range (IQR): 29-95] staff completed personal protective equipment (PPE) training, 94 [IQR: 90-104] staff completed antigen testing and 51 [IQR: 32-136] staff completed polymerase chain reaction testing. The operation focused on building a safe environment with infection prevention and control adherence and workforce sustainability. There was no leakage of SARS-CoV-2 to staff or the community and no PPE compromises requiring staff to quarantine for 14 days. CONCLUSION: HSIQF demonstrates the operationalisation of an effective, safe and replicable quarantine system. IMPLICATIONS FOR PUBLIC HEALTH: Quarantine is a critical public health tool for pandemic control. The HSIQF operations may be useful to inform the establishment and management of quarantine facilities for future and current disease outbreaks.

An evaluation of enhanced surveillance of hospitalised COVID-19 patients to inform the public health response in Victoria.

BACKGROUND: Public health surveillance is crucial for supporting a rapid and effective response to public health emergencies. In response to the coronavirus disease (COVID-19) pandemic, an enhanced surveillance system of hospitalised COVID-19 patients was established by the Victorian Department of Health and Human Services (DHHS) and the Victorian Healthcare Associated Infection Surveillance System Coordinating Centre. The system aimed to reduce workforce capacity constraints and increase situational awareness on the status of hospitalised patients. METHODS: The system was evaluated, using guidelines from the United States Centers for Disease Control and Prevention, against eight attributes: acceptability; data quality; flexibility; representativeness; simplicity; stability; timeliness; and usefulness. Evidence was generated from stakeholder consultation, participant observation, document review, systems review, issues log review and audits. Data were collected and analysed over a period of up to three months, covering pre- and post-implementation from March to June 2020. RESULTS: This system was rapidly established by leveraging established relationships and infrastructure. Stakeholders agreed that the system was important but was limited by a reliance on daily manual labour (including weekends), which impeded scalability. The ability of the system to perform well in each attribute was expected to shift with the severity of the pandemic; however, at the time of this evaluation, when there were an average 23 new cases per day (0.3 cases per 100,000 population per day), the system performed well. CONCLUSION: This enhanced surveillance system was useful and achieved its key DHHS objectives during the COVID-19 public health emergency in Victoria. Recommendations for improvement were made to the current and future systems, including the need to plan alternatives to improve the system's scalability and to maintain stakeholder acceptability.
