Prehospital care and transport costs of severely injured children in NSW Australia.

BACKGROUND: Injury is the leading cause of childhood death and disability in Australia. Prehospital emergency services in New South Wales (NSW) are provided by NSW Ambulance. The incidence, pre-hospital care provided and outcomes of children suffering major injury in NSW has not previously been described. METHODS: This retrospective study was conducted between July 2015 and September 2016 and included children <16 years with an injury severity score (ISS) >9, or requiring intensive care admission, or deceased following injury and treated in NSW. Children were identified through the three NSW Paediatric Trauma Centres, the NSW Trauma Registry, NSW Medical Retrieval Registry (AirMaestro, Avinet, Australia). RESULTS: There were 359 majorly injured children treated by NSW-based emergency service providers, the majority were male (73.3%) with a mean (SD) age of 8.0 (5.2) years. The median (IQR) injury severity score (ISS) for those transported via NSW emergency medical services was 10 (9-17), with almost half (44.1%) treated prehospital having an ISS >12. The most common documented interventions were intravenous access (44.1%) and oxygen therapy (39.6%). Intubation and chest decompression were recorded in 15.3% and 3.1% of cases respectively. The calculated median (IQR) transport charges for NSW Emergency Services was AUD $942 ($841.3-$1184.6). CONCLUSION: Critical interventions are performed infrequently in children with major injuries in the pre-hospital environment. The monitoring of the incidence and success rates for staff performing these interventions is not readily available from all prehospital emergency medical services operating in NSW. The capacity and processes to monitor and audit all critical interventions in the paediatric population should be resourced and clearly defined.

Toxicological analysis of serious drug-related harm among electronic dance music festival attendees in New South Wales, Australia: A consecutive case series.

BACKGROUND: A substantial increase in drug-related harm was observed during the 2018-2019 music festival season in New South Wales, Australia, including the deaths of five young people. As part of a rapid public health response, the New South Wales Ministry of Health referred samples from patients with suspected severe drug-related illness for forensic toxicological testing to identify the type and concentration of substances associated with the presentations. METHODS: Cases were identified through a variety of active and passive surveillance systems, and selected consecutively based on indicators of clinical severity. Comprehensive toxicology testing of blood and urine samples was expedited for all cases. Demographic and clinical characteristics were collated, together with quantitative toxicology results. Results were analysed using descriptive statistics. RESULTS: Forty cases from eleven different music festivals were included. The majority of cases (80.0%) were aged 25 years and under. There were five fatalities, and 62.5% of cases were admitted to intensive care units. MDMA was the most frequent substance, detected in 87.5% of cases. In 82.9% of cases with MDMA, blood concentrations were above thresholds that have been associated with toxicity. Multiple substances were detected in 60.0% of cases. Novel psychoactive substances were not detected. CONCLUSIONS: Our findings strongly suggest that MDMA-related toxicity was a major factor in the severity of the clinical presentations among these cases. Other substances may have enhanced MDMA toxicity but appear unlikely to have caused severe toxicity in isolation. These findings have important implications for harm reduction strategies targeted to music festival settings.

Determining the priorities for change in paediatric trauma care delivery in NSW, Australia.

BACKGROUND: Injury remains the leading cause of death and disability for Australian children. There is known variability in the quality of care delivered to injured children in Australia. This study prioritises recommendations developed from an expert review of paediatric trauma cases, for implementation with the aim of improving health service delivery to children sustaining severe injury. METHODS: A modified-Delphi study was conducted between October 2018 and February 2019. Two rounds of an online survey to rank the suitability and importance of each of the 26 recommendations was conducted. Final decisions on the priorities for change in the paediatric trauma system was determined by a consensus of ≥80% for importance and/or suitability. RESULTS: One hundred and one participants completed Round 1, and 60 participants completed Round 2 of the modified-Delphi. In Round 1, 13 recommendations reached ≥80% and in round 2, 11 recommendations reached ≥80%. Those ranked highest focussed on pre-hospital airway management, streamlining retrieval and transfer processes, improving hospital nursing ratios and radiology reporting. CONCLUSION: This modified-Delphi study identified the priority areas for recommended change to the NSW paediatric trauma system. Work to address these areas has the potential to provide more coordinated and timely care to children sustaining severe injury.

Identifying areas for improvement in paediatric trauma care in NSW Australia using a clinical, system and human factors peer-review tool.

BACKGROUND: There is known variability in the quality of care delivered to injured children. Identifying where care improvement can be made is critical. This study aimed to review paediatric trauma cases across the most populous Australian State to identify factors contributing to clinical incidents. METHODS: Medical records from three New South Wales Paediatric Trauma Centres were reviewed for children <16 years requiring intensive care; with an injury severity score of ≥9, or who died following injury between July 2015 and September 2016. Records were peer-reviewed by nurse surveyors who identified cases that might not meet the expected standard of care or where the child died following the injury. A multidisciplinary panel conducted the peer-review using a major trauma peer-review tool. Records were reviewed independently, then discussed to establish consensus. RESULTS: A total 535 records were reviewed and 41 cases were peer-reviewed. The median (IQR) age was 7 (2-12) years, the median ISS was 25 (IQR 16-30). The peer-review identified a combination of clinical (85%), systems (51%) and communication (12%) problems that contributed to difficulties in care delivery. In 85% of records, staff actions were identified to contribute to events; with medical task failure the most frequently identified cause (89%). CONCLUSION: The peer-review of paediatric trauma cases assisted in the identification of contributing factors to clinical incidents in trauma care resulting in 26 recommendations for change. The prioritisation and implementation of these recommendations, alongside a uniform State-wide trauma case review process with consistent criteria (definitions), performance indicators, monitoring and reporting would facilitate improvement in health service delivery to children sustaining severe injury.

Pre-hospital and retrieval medicine: Clinical governance and workforce models.

Pre-hospital and retrieval medicine (PHARM) has developed significantly in the past decade. This perspective article proposes that PHARM should develop with a clear focus on contemporary health governance principles, and that its workforce and models of care adopt modern interdisciplinary approaches. Many of the older systems of managing clinical standards, and outdated cultural approaches to professional 'turf', workforce and scope of practice have little place in high-performance organisations. This paper calls us to attention with a recommendation that best and safest systems of care, structured to optimise patient outcomes and system performance should be our goal.

Development of the major trauma case review tool.

BACKGROUND: As many as half of all patients with major traumatic injuries do not receive the recommended care, with variance in preventable mortality reported across the globe. This variance highlights the need for a comprehensive process for monitoring and reviewing patient care, central to which is a consistent peer-review process that includes trauma system safety and human factors. There is no published, evidence-informed standardised tool that considers these factors for use in adult or paediatric trauma case peer-review. The aim of this research was to develop and validate a trauma case review tool to facilitate clinical review of paediatric trauma patient care in extracting information to facilitate monitoring, inform change and enable loop closure. METHODS: Development of the trauma case review tool was multi-faceted, beginning with a review of the trauma audit tool literature. Data were extracted from the literature to inform iterative tool development using a consensus approach. Inter-rater agreement was assessed for both the pilot and finalised versions of the tool. RESULTS: The final trauma case review tool contained ten sections, including patient factors (such as pre-existing conditions), presenting problem, a timeline of events, factors contributing to the care delivery problem (including equipment, work environment, staff action, organizational factors), positive aspects of care and the outcome of panel discussion. After refinement, the inter-rater reliability of the human factors and outcome components of the tool improved with an average 86% agreement between raters. DISCUSSION: This research developed an evidence-informed tool for use in paediatric trauma case review that considers both system safety and human factors to facilitate clinical review of trauma patient care. CONCLUSIONS: This tool can be used to identify opportunities for improvement in trauma care and guide quality assurance activities. Validation is required in the adult population.

Paediatric trauma systems and their impact on the health outcomes of severely injured children: protocol for a mixed methods cohort study.

BACKGROUND: Injury is a leading cause of death and disability for children. Regionalised trauma systems have improved outcomes for severely injured adults, however the impact of adult orientated trauma systems on the outcomes of severely injured children remains unclear. The objective of this study is to review the processes of care and describe the impacts of a regionalised trauma system on the outcomes of severely injured children. METHODS: This article describes the design of a mixed methods cohort study evaluating the paediatric trauma system in New South Wales (NSW), the most populous state in Australia. Recommendations and an implementation strategy will be developed for aspects of the paediatric trauma care system that require change. All injured children (aged <16 years) requiring intensive care, or with an Injury Severity Score (ISS) ≥ 9 treated in NSW, or who died following injury in NSW in the 2015-16 financial year, will be eligible for participation. Injury treatment and processes will be examined via retrospective medical record review. Quality of care will be measured via peer review and staff interviews, utilising a human factors framework. Health service and cost outcomes will be calculated using activity based funding data provided by the Ministry of Health. Health-related quality of life (HRQoL) proxy measures will occur at baseline, 6 and 12 months to measure child HRQoL and functional outcomes. DISCUSSION: This will be the first comprehensive analysis undertaken in Australia of the processes and systems of care for severe paediatric injury. The collaborative research method will encourage clinician, consumer and clinical networks to lead the clinical reform process and will ultimately enable policy makers and service providers to ensure that children seriously injured in Australia have the best opportunity for survival, improved functional outcome and long-term quality of life.

An investigation into the cost, coverage and activities of Helicopter Emergency Medical Services in the state of New South Wales, Australia.

BACKGROUND AND CONTEXT: Helicopter Emergency Medical Services (HEMS) have been incorporated into modern health systems for their speed and coverage. In the state of New South Wales (NSW), nine HEMS operate from various locations around the state and currently there is no clear picture of their resource implications. The aim of this study was to assess the cost of HEMS in NSW and investigate the factors linked with the variation in the costs, coverage and activities of HEMS. METHODS: We undertook a survey of HEMS costs, structures and operations in NSW for the 2008/2009 financial year. Costs were estimated from annual reports and contractual agreements. Data related to the structure and operation of services was obtained by face-to-face interviews, from operational data extracted from individual HEMS, from the NSW Ambulance Computer Aided Despatch system and from the Aeromedical Operations Centre database. In order to estimate population coverage for each HEMS, we used GIS mapping techniques with Australian Bureau of Statistics census information. RESULTS: Across HEMS, cost per mission estimates ranged between $9300 and $19,000 and cost per engine hour estimates ranged between $5343 and $15,743. Regarding structural aspects, six HEMS were run by charities or not-for-profit companies (with partial government funding) and three HEMS were run (and fully funded) by the state government through NSW Ambulance. Two HEMS operated as 'hub' services in conjunction with three associated 'satellite' services and in contrast, four services operated independently. Variation also existed between the HEMS in the type of helicopter used, the clinical staffing and the hours of operation. The majority of services undertook both primary scene responses and secondary inter-facility transfers, although the proportion of each type of transport contributing to total operations varied across the services. INTERPRETATION: This investigation highlighted the cost of HEMS operations in NSW which in total equated to over $50 million per annum. Across services, we found large variation in the cost estimates which was underscored by variation in the structure and operations of HEMS.

Logistics and safety of extracorporeal membrane oxygenation in medical retrieval.

OBJECTIVE: This article reviews the logistics and safety of extracorporeal membrane oxygenation (ECMO) medical retrieval in New South Wales, Australia. METHODS: We describe the logistics involved in ECMO road and rotary-wing retrieval by a multidisciplinary team during the H1N1 influenza epidemic in winter 2009 (i.e., June 1 to August 31, 2009). Basic patient demographics and key retrieval time lines were analyzed. RESULTS: There were 17 patients retrieved on ECMO, with their ages ranging from 22 to 55 years. The median weight was 110 kg. Four critical events were recorded during retrieval, with no adverse outcomes. The retrieval distance varied from 20.8 to 430 km. There were delays in times from retrieval booking to both retrieval tasking and retrieval team departure in 88% of retrievals. The most common reasons cited were "patient not ready" 23.5% (4/17); "vehicle not available," 23.5% (4/17); and "complex retrieval," 41.2% (7/17). The median time (hours:minutes) from booking with the medical retrieval unit (MRU) to tasking was 4:35 (interquartile range [IQR] 3:27-6:15). The median time lag from tasking to departure was 1:00 (IQR 00:10-2:20). The median stabilization time was 1:30 (IQR 1:20-1:55). The median retrieval duration was 7:35 (IQR 5:50-10:15). CONCLUSION: The process of development of ECMO retrieval was enabled by the preexistence of a high-volume experienced medical retrieval service. Although ECMO retrieval is not a new concept, we describe an entire process for ECMO retrieval that we believe will benefit other retrieval service providers. The increased workload of ECMO retrieval during the swine flu pandemic has led to refinement in the system and process for the future.

The accuracy of external blood loss estimation by ambulance and hospital personnel.

OBJECTIVE: To determine if emergency personnel, either ambulance or hospital based, can estimate the volume of external blood loss accurately enough to be of potential clinical use in guiding fluid resuscitation. METHODS: A total of 61 ambulance and 35 hospital personnel viewed nine scenarios consisting of volumes of blood (100 mL, 400 mL and 700 mL) spilt onto three surfaces--carpet, vinyl and a clothed manikin. They were asked to estimate the blood loss in each case. RESULTS: Estimates of volumes of blood loss on all surfaces were generally inaccurate. Both ambulance and hospital groups were comparable in this regard. Hospital personnel had higher mean estimates than those of ambulance personnel. Of particular clinical relevance were the findings that blood loss on carpet was underestimated and small volumes on a clothed manikin were overestimated. CONCLUSION: External blood loss estimation by ambulance and hospital personnel is generally too inaccurate to be of clinical use.
