Hot of Not: Physiological versus Meteorological Heatwaves-Support for a Mean Temperature Threshold
The aim of this study was to determine whether a revised heat warning threshold provides an enhanced predictive tool for increases in Emergency Department heat-related presentations in Canberra, Australia. All Emergency Department triage records containing the word "heat", as well as those diagnosing a heat related illness for the summer periods 2013/2014, 2014/2015, and 2015/2016 were searched. Then a medical record review was conducted to confirm that the patient's presentation was related to environmental heat, which was defined by the final clinical diagnosis, presentation complaint and details of the patient's treatment. Researchers then compared this presentation data, to a mean threshold formula. The mean threshold formula included the past three consecutive daily mean temperatures and the last measured temperature upon presentation. This formula was designed to take into account the variance of night-time lows, with concurrent daily ambient temperatures, and was used to determine whether there was a correlation between heat-related presentations and increasing mean temperatures. Heat-related presentations appeared to occur when the mean threshold temperature reached 25 °C (77 °F), with significant increases when the mean threshold reached 30 °C (86 °F). These results confirm that a mean temperature of 30 °C corresponds to a relevant local public health heat-related threat
Childhood outcomes after low-grade intraventricular haemorrhage: A systematic review and meta-analysis
Aim: To undertake a systematic review and meta-analysis exploring school-age neurodevelopmental outcomes of children after low-grade intraventricular haemorrhage (IVH). Method: The published and grey literature was extensively searched to identify observational comparative studies exploring neurodevelopmental outcomes after IVH grades 1 and 2. Our primary outcome was neurodevelopmental impairment after 5 years of age, which included cognitive, motor, speech and language, behavioural, hearing, or visual impairments. Results: This review included 12 studies and over 2036 infants born preterm with low grade IVH. Studies used 30 different neurodevelopmental tools to determine outcomes. There was conflicting evidence of the composite risk of neurodevelopmental impairment after low-grade IVH. There was evidence of an association between low-grade IVH and lower IQ at school age (−4.23, 95% confidence interval [CI] –7.53, −0.92, I2 = 0%) but impact on school performance was unclear. Studies reported an increased crude risk of cerebral palsy after low-grade IVH (odds ratio [OR] 2.92, 95% CI 1.95, 4.37, I2 = 41%). No increased risk of speech and language impairment or behavioural impairment was found. Few studies addressed hearing and visual impairment. Interpretation: This systematic review presents evidence that low-grade IVH is associated with specific neurodevelopmental impairments at school age, lending support to the theory that low-grade IVH is not a benign condition
School-age outcomes of children after perinatal brain injury: a systematic review and meta-analysis
BACKGROUND: Over 3000 children suffer a perinatal brain injury in England every year according to national surveillance. The childhood outcomes of infants with perinatal brain injury are however unknown. METHODS: A systematic review and meta-analyses were undertaken of studies published between 2000 and September 2021 exploring school-aged neurodevelopmental outcomes of children after perinatal brain injury compared with those without perinatal brain injury. The primary outcome was neurodevelopmental impairment, which included cognitive, motor, speech and language, behavioural, hearing or visual impairment after 5 years of age. RESULTS: This review included 42 studies. Preterm infants with intraventricular haemorrhage (IVH) grades 3-4 were found to have a threefold greater risk of moderate-to-severe neurodevelopmental impairment at school age OR 3.69 (95% CI 1.7 to 7.98) compared with preterm infants without IVH. Infants with perinatal stroke had an increased incidence of hemiplegia 61% (95% CI 39.2% to 82.9%) and an increased risk of cognitive impairment (difference in full scale IQ -24.2 (95% CI -30.73 to -17.67) . Perinatal stroke was also associated with poorer academic performance; and lower mean receptive -20.88 (95% CI -36.66 to -5.11) and expressive language scores -20.25 (95% CI -34.36 to -6.13) on the Clinical Evaluation of Language Fundamentals (CELF) assessment. Studies reported an increased risk of persisting neurodevelopmental impairment at school age after neonatal meningitis. Cognitive impairment and special educational needs were highlighted after moderate-to-severe hypoxic-ischaemic encephalopathy. However, there were limited comparative studies providing school-aged outcome data across neurodevelopmental domains and few provided adjusted data. Findings were further limited by the heterogeneity of studies. CONCLUSIONS: Longitudinal population studies exploring childhood outcomes after perinatal brain injury are urgently needed to better enable clinicians to prepare affected families, and to facilitate targeted developmental support to help affected children reach their full potential
Aeromedical retrieval services characteristics globally: a scoping review
Background
Aeromedical emergency retrieval services play an important role in supporting patients with critical and often life-threatening clinical conditions. Aeromedical retrieval services help to provide fast access to definitive care for critically ill patients in under-served regions. Typically, fixed-wing aeromedical retrieval becomes the most viable transport option compared with rotary-wing aircraft when distances away from centres of definitive care extend beyond 200 kms. To our knowledge, there are no studies that have investigated fixed-wing aeromedical services in the member countries of the organisation for economic cooperation and development (OECD). A description of the global characteristics of aeromedical services will inform international collaboration to optimise clinical outcomes for patients.
Aim
In this scoping review, we aimed to describe the features of government- and not-for-profit organisation-owned fixed-wing aeromedical retrieval services in some of the member countries of the OECD.
Methods
We followed scoping review methodology based on the grey literature search strategy identified in earlier studies. This mostly involved internet-based searches of the websites of fixed-wing aeromedical emergency retrieval services affiliated with the OECD member countries.
Results
We identified 460 potentially relevant records after searching Google Scholar (n = 24) and Google search engines (n = 436). After removing ineligible and duplicate information, this scoping review identified 86 government-and not-for-profit-operated fixed-wing aeromedical retrieval services as existing in 17 OECD countries. Concentrations of the services were greatest in the USA followed by Australia, Canada, and the UK. The most prevalent business models used across the identified OECD member countries comprised the government, not-for-profit, and hybrid models. Three-quarters of the not-for-profit and two-fifths of the hybrid business models were in the USA compared to other countries studied. The government or state-funded business model was most common in Australia (11/24, 46%), Canada (4/24, 17%), and the UK (4/24, 17%). The frequently used service delivery models adopted for patients of all ages included primary/secondary retrievals, secondary retrievals only, and service specialisation models. Of these service models, primary/secondary retrieval involving the transportation of adults and children from community clinics and primary health care facilities to centres of definitive care comprised the core tasks performed by most of the aeromedical retrieval services studied. The service specialisation model provided an extra layer of specialist health care dedicated to the transportation of neonates and paediatrics. At least eight aeromedical retrieval services catered solely for children from birth to 16 years of age. One aeromedical service, the royal flying doctor service in Australia also provided primary health care and telehealth services in addition to primary retrieval and interhospital transfer of patients. The doctor and registered nurse/paramedic (Franco-German model) and the nurse and/or paramedic (Anglo-American model) configurations were the most common staffing models used across the aeromedical services studied.
Conclusions
The development and composition of fixed-wing aeromedical emergency retrieval services operated by not-for-profit organisations and governments in the OECD countries showed diversity in terms of governance arrangements, services provided, and staffing models used. We do not fully understand the impact of these differences on the quality of service provision, including equitable service access, highlighting a need for further research.publishedVersio
A novel COVID-19 program, delivering vaccines throughout rural and remote Australia
BackgroundThe Royal Flying Doctor Service of Australia (RFDS) established a unique SARS-CoV-2 vaccination program for vaccinating Australians that live in rural and remote areas. This paper describes the preparation and response phases of the RFDS response.MethodsThis study includes vaccinations conducted by the RFDS from 01 January 2021 until 31 December 2021 when vaccines were mandatory for work and social activities. Prior to each clinic, we conducted community consultation to determine site requirements, patient characteristics, expected vaccination numbers, and community transmission rates.FindingsNinety-five organizations requested support. The majority (n = 60; 63.2%) came from Aboriginal Community Controlled Health Organizations. Following consultation, 360 communities were approved for support. Actual vaccinations exceeded expectations (n = 70,827 vs. 49,407), with a concordance correlation coefficient of 0.88 (95% CI, 0.83, 0.93). Areas that reported healthcare workforce shortages during the preparation phase had the highest population proportion difference between expected and actual vaccinations. Areas that reported high vaccine hesitancy during the preparation phase had fewer than expected vaccines. There was a noticeable increase in vaccination rates in line with community outbreaks and positive polymerase chain reaction cases [r (41) = 0.35, p = 0.021]. Engagement with community leaders prior to clinic deployment was essential to provide a tailored response based on community expectations
Poor access to kidney disease management services in susceptible patient populations in rural Australia is associated with increased aeromedical retrievals for acute renal care
Background
Inequalities in access to renal services and acute care for rural and remote populations in Australia have been described but not quantified.
Aim
To describe: the coverage of renal disease management services in rural and remote Australia; and the characteristics of patients who had an aeromedical retrieval for renal disease by Australia's Royal Flying Doctor Service (RFDS).
Methods
Data from the RFDS, the Australian Bureau of Statistics, and Health Direct were used to estimate provision of renal disease management services by geographic area. RFDS patient diagnostic data were prospectively collected from 2014 to 2018.
Results
Many rural and remote areas have limited access to regular renal disease management services. Most RFDS retrievals for renal disease are from regions without such services. The RFDS conducted 1636 aeromedical retrievals for renal disease, which represented 1.6% of all retrievals. Among retrieved patients, there was a higher proportion of men than women (54.6% vs 45.4%, P < 0.01), while indigenous patients (n = 546, 33.4%) were significantly younger than non‐indigenous patients (40.9 vs 58.5, P < 0.01). There were significant differences in underlying diagnoses triggering retrievals between genders, with males being more likely than females to be transferred with acute renal failure, calculus of the kidney and ureter, renal colic, obstructive uropathy, and kidney failure (all P < 0.01). Conversely, females were more likely to have chronic kidney disease, disorders of the urinary system, acute nephritic syndrome, tubulo‐interstitial nephritis, and nephrotic syndrome (all P < 0.01).
Conclusion
Aeromedical retrievals for acute care were from rural areas without regular access to renal disease prevention or management services
Rural and remote dental care: Patient characteristics and health care provision
Objective: To describe the characteristics of patients who used the Royal Flying Doctor Service dental clinics and determine Royal Flying Doctor Service and nonRoyal Flying Doctor Service dental service provision in mainland Australia. Design: A prospective cohort study. Setting: All Royal Flying Doctor Service dental clinics located throughout rural and remote Australia. Participants: All patients who accessed an Royal Flying Doctor Service dental clinic from April 2017 to September 2018. Interventions: Royal Flying Doctor Service mobile dental clinics. Main outcome measures: Patient demographics and dental procedures conducted (by age, sex and Indigenous status); and the dental service provision and coverage (Royal Flying Doctor Service and non-Royal Flying Doctor Service) within mainland rural and remote Australia. Results: There were 8992 patient episodes comprising 3407 individual patients with 27 897 services completed. There were 920 (27%) Indigenous and 1465 (43%) nonIndigenous patients (n = 1022 missing ethnicity data). The mean (SD) age was 31.5 (24.8) years; the age groups 5-9 years and 10-14 years received 17.6% and 15.1% of the services, respectively. There were 1124 (33%) men and 1295 (38%) women (n = 988 with missing sex data). Women were more likely (all P < .05) to receive preventive services, diagnostic services, restorative services, general services, endodontics and periodontics. Men were more likely (both P < .05) to receive oral surgery and prosthodontics. There are many rural and remote people required to travel more than 60 minutes by vehicle to access dental care. Conclusion: Without increasing dental provision and preventive services in rural areas, it seems likely that there are and will be unnecessary oral emergencies and hospitalisations
