Aeromedical retrievals in Queensland: A five-year review.

OBJECTIVE: Aeromedical services are an essential part of the healthcare system. Centralised coordination of aeromedical retrieval tasking offers benefits for safety, timeliness and efficiency in service delivery. The aim of the present study is to review aeromedical retrievals in Queensland exploring patient demographics, temporal patterns and usage characteristics. METHODS: This is a retrospective cases series for the period 1 January 2010 to 31 December 2014 incorporating data from Retrieval Services Queensland and Queensland Newborn Emergency Transport Service. Ethics approval was obtained (JCU-HREC H6137 and Public Health Act #RD005673). Descriptive analysis of the de-identified data was undertaken included patient demographics, referral and receiving locations, retrieval platform and acuity of transport request. RESULTS: There were 73 042 aeromedical retrievals undertaken during the period, with an average of 40 cases per day (range 16-89). The majority (95%) of retrievals were for Queensland residents. Overall 23.1% of cases were cardiology-related and 12.7% were injury-related. Older adults aged 75-84 years had the highest rate of retrievals relative to the population with a crude rate of 942.4 per 100 000 per annum. Overall 14.9% of cases were Priority 1, which represents the tasking with the highest acuity but majority were Priority 4 (41.6%). One third (37.6%) of all patients were from inner regional locations. CONCLUSIONS: Potential investments in health service planning may alleviate the burden on aeromedical services, particularly related to cardiology services in inner and outer regional Queensland. Aeromedical services are pivotal in enabling all sick and injured residents' access to the highest quality of care regardless of the remoteness of their residence.

Review article: Primary aeromedical retrievals in Australia: An interrogation and search for context.

Primary aeromedical retrievals are a direct scene response to patients with a critical injury or illness using a medically equipped aircraft. They are often high-acuity taskings. In Australia, information on primary retrieval taskings is housed by service providers, of which there are many across the country. This exploratory literature review aims to explore the contemporary peer-reviewed literature on primary aeromedical retrievals in Australia. The focus is on adult primary aeromedical retrievals undertaken in Australia and clinical tools used in this pre-hospital setting. Included articles were reviewed for research theme (clinical and equipment, systems and/or outcomes), data coverage and appraisal of the evidence. Of the 37 articles included, majority explored helicopter retrievals (n = 32), retrieval systems (n = 21), compared outcomes within a service (n = 10) and explored retrievals in the state of New South Wales (n = 19). Major topics of focus included retrieval of trauma patients and airway management. Overall, the publications had a lower strength of evidence because of the preponderance of cross-sectional and case-study methodology. This review provides some preliminary but piecemeal insight into primary retrievals in Australia through a localised systems lens. However, there are several areas for research action and service outcome improvements suggested, all of which would be facilitated through the creation of a national pre-hospital and retrieval registry. The creation of a registry would enable consideration of the frequency and context of retrievals, comparison across services, more sophisticated data interrogation. Most importantly, it can lead to service and pre-hospital and retrieval system strengthening.

A 3-year retrospective audit of the use of noninvasive positive pressure ventilation via the Oxylog 3000 transport ventilator during air medical retrievals.

INTRODUCTION: The purpose of this study was to describe the safety profile of noninvasive positive pressure ventilation (NIPPV) using the Oxylog 3000 transport ventilator (Drager Medical, Lübeck, Germany) by air medical retrieval teams from the Queensland Section of the Royal Flying Doctor Service of Australia. METHODS: Over a 3-year period, patients identified in clinical transport records to have NIPPV via the Oxylog 3000 transport ventilator during air medical transfer were systematically reviewed on the clinical indication and adverse effects. RESULTS: A total of 29 patients were identified to have had treatment with NIPPV during air medical retrieval. Three patients suffered serious adverse effects of cardiorespiratory arrest during treatment. The main reported adverse event was intolerance of the facemask. There were no documented episodes of vomiting or hypotension. CONCLUSION: The use of NIPPV via the Oxylog 3000 transport ventilator during air medical retrieval requires careful patient selection. The application and management do not differ from standard hospital-based practice.
