A retrospective observational study of vCare: a virtual emergency clinical advisory and transfer service in rural and remote Australia.

BACKGROUND: Provision of critical care in rural areas is challenging due to geographic distance, smaller facilities, generalist skill mix and population characteristics. Internationally, the amalgamation telemedicine and retrieval medicine services are developing to overcome these challenges. Virtual emergency clinical advisory and transfer service (vCare) is one of these novel services based in New South Wales, Australia. We aim to describe patient encounters with vCare from call initiation at the referring site to definitive care at the accepting site. METHODS: This retrospective observational study reviewed all patients using vCare in rural and remote Australia for clinical advice and/or inter-hospital transfer for higher level of care between February and March 2021. Data were extracted from electronic medical records and included remoteness of sites, presenting complaint, triage category, camera use, patient characteristics, transfer information, escalation of therapeutic intervention and outcomes. Data were summarised using cross tabulation. RESULTS: 1,678 critical care patients were supported by vCare, with children (12.5%), adults (50.6%) and older people (36.9%) evenly split between sexes. Clinicians mainly referred to vCare for trauma (15.1%), cardiac (16.1%) and gastroenterological (14.8%) presentations. A referral to vCare led to an escalation of invasive intervention, skill, and resources for patient care. vCare cameras were used in 19.8% of cases. Overall, 70.5% (n = 1,139) of patients required transfer. Of those, 95.1% were transferred to major regional hospitals and 11.7% required secondary transfer to higher acuity hospitals. Of high-urgency referrals, 42.6% did not receive high priority transport. Imaging most requested included CT and MRI scans (37.2%). Admissions were for physician (33.1%) and surgical care (23.3%). The survival rate was 98.6%. CONCLUSION: vCare was used by staff in rural and remote facilities to support decision making and care of patients in a critical condition. Issues were identified including low utilisation of equipment, heavy reliance on regional sites and high rates of secondary transfer. However, these models are addressing a key gap in the health workforce and supporting rural and remote communities to receive care.

Flooding and Arboviral Disease: Predicting Ross River Virus Disease Outbreaks Across Inland Regions of South-Eastern Australia.

Flood frequency is expected to increase across the globe with climate change. Understanding the relationship between flooding and arboviral disease can reduce disease risk and associated costs. South-eastern Australia is dominated by the flood-prone Murray-Darling River system where the incidence of Australia's most common arboviral disease, Ross River virus (RRV), is high. This study aimed to determine the relationship between riverine flooding and RRV disease outbreaks in inland south-eastern Australia, specifically New South Wales (NSW). Each study month from 1991 to 2013, for each of 37 local government areas (LGAs) was assigned 'outbreak/non-outbreak' status based on long-term trimmed-average age-standardized RRV notification rates and 'flood/non-flood' status based on riverine overflow. LGAs were grouped into eight climate zones with the relationship between flood and RRV outbreak modeled using generalized estimating equations. Modeling adjusted for rainfall in the previous 1-3 mo. Spring-summer flooding increased the odds of summer RRV outbreaks in three climate zones before and after adjusting for rainfall 1, 2, and 3 mo prior to the outbreak. Flooding at any time of the year was not predictive of RRV outbreaks in the remaining five climate zones. Predicting RRV disease outbreaks with flood events can assist with more targeted mosquito spraying programs, thereby reducing disease transmission and mosquito resistance.

Implementing an anti-smoking program in rural-remote communities: challenges and strategies.

INTRODUCTION: Rural-remote communities report higher smoking rates and poorer health outcomes than that of metropolitan areas. While anti-smoking programs are an important measure for addressing smoking and improving health, little is known of the challenges faced by primary healthcare staff implementing those programs in the rural-remote setting. The aim of this study was to explore the challenges and strategies of implementing an anti-smoking program by primary healthcare staff in rural-remote Australia. METHODS: Guided by a phenomenological approach, semi-structured interviews and focus groups were conducted with health service managers, case managers and general practitioners involved in program implementation in Australian rural-remote communities between 2008 and 2010. RESULTS: Program implementation was reported to be challenged by limited primary and mental healthcare resources and client access to services; limited collaboration between health services; the difficulty of accessing staff training; high levels of community distress and disadvantage; the normalisation of smoking and its deleterious impact on smoking abstinence among program clients; and low morale among health staff. Strategies identified to overcome challenges included appointing tobacco-dedicated staff; improving health service collaboration, access and flexibility; providing subsidised pharmacotherapies and boosting staff morale. CONCLUSIONS: Findings may assist health services to better tailor anti-smoking programs for the rural-remote setting, where smoking rates are particularly high. Catering for the unique challenges of the rural-remote setting is necessary if anti-smoking programs are to be efficacious, cost-effective and capable of improving rural-remote health outcomes.

Ross River Virus Disease Activity Associated With Naturally Occurring Nontidal Flood Events in Australia: A Systematic Review.

Ross River virus (RRV) disease is the most common and widespread mosquito-borne disease in Australia, resulting in considerable health and economic cost to communities. While naturally occurring nontidal flood events may enhance mosquito abundance, little is known about the impact of such events on RRV transmission. This article critically reviews the existing evidence for an association between naturally occurring nontidal flood events and RRV transmission. A systematic literature search was conducted on RRV transmission related to flooding and inundation from rain and riverine overflow. Overall, the evidence to support a positive association between flooding and RRV outbreaks is largely circumstantial, with the literature mostly reporting only coincidental occurrence between the two. However, for the Murray River, river flow and height (surrogates of flooding) were positively and significantly associated with RRV transmission. The association between nontidal flooding and RRV transmission has not been studied comprehensively. More frequent flood events arising from climate change may result in increased outbreaks of RRV disease. Understanding the link between flood events and RRV transmission is necessary if resources for mosquito spraying and public health warnings are to be used more effectively and efficiently.

Ross River virus disease in inland NSW: higher than average notifications in 2007-08.

This study showed that Ross River virus notifications in the Greater Western Area Health Service of NSW were higher in 2007-08 than any other financial year for the 1997-2009 period. The study also examined the epidemiology of those notifications. Notification and population data were retrieved from the NSW Health Notifiable Diseases Database and HOIST Populations Library respectively. Age-standardised notification rates were highest in Bogan, Bourke, Brewarrina, Gilgandra, Narromine, Walgett and Warren. Notifications peaked for the 35-39-year age group and were evenly distributed between the sexes. Notifications peaked in February. Aboriginal status was under-reported.
