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

Remoteness and socioeconomic status reduce access to specialist mental health care across Australia

Objective: Estimate impact of socioeconomic factors and remoteness from tertiary hospital on incidence/duration of Australian mental health admissions. Methods: Retrospective analysis of incidence/duration of public mental health unit admissions (2018–19). Covariates included Indigenous population, potentially preventable hospitalisations (PPH) and socioeconomic disadvantage. Results: Regional distance from hospital was correlated with socioeconomic disadvantage (ρ: p < 0.01). Population identifying as Aboriginal or Torres Strait Islander was associated with distance from hospital, socioeconomic disadvantage and PPH (ρ: p < 0.01). Bed days per capita was explained (R2adj: 0.48) by distance and socioeconomic disadvantage (p < 0.0001). A 1% increase in distance from hospital was associated with a 0.37% decrease in per capita bed days. Admission rate per capita across Queensland and WA was explained (R2adj: 0.36) by distance, education/occupation and state (p < 0.05). Across Queensland and WA a 1% increase in distance from hospital was associated with a 0.05% decreased incidence of admission. Conclusions: Rural Australians face high mental illness burden, socioeconomic disadvantage and limited service provision. Overcoming the additional disadvantages of reduced likelihood of admission to and reduced time in hospital with increasing distance from hospital will require increased outreach proportional to remoteness

A cohort comparison study on women in threatened preterm labor given nifedipine or nifedipine and salbutamol tocolysis in air medical retrieval

Objective: Women with threatened preterm labor in remote Australia often require tocolysis in the prevention of in-flight birth during air medical retrieval. However, debate exists over the tocolytic choice. Methods: A retrospective analysis was undertaken on data containing women who required air medical retrieval for threatened preterm labor within Western Australia between the years 2013 and 2018. Results: A total number of 236 air medical retrievals were deemed suitable for inclusion; 141 received nifedipine, and 95 women received salbutamol + nifedipine. Tocolytic efficaciousness was reported in 151 cases, proportionally more (P \u3c .05) from the women who received salbutamol + nifedipine (n = 68, 71.6%) compared with the women who received nifedipine only (n = 83, 58.9%). Those receiving salbutamol + nifedipine were more likely to suffer maternal tachycardia (n = 87 [91.6%] vs. n = 62 [44.0%]), fetal tachycardia (n = 26 [27.4%] vs. n = 13 [9.2%]), nausea (n = 17 [17.9] vs. n = 5 [3.55%]), and vomiting (n = 12 [12.6%] vs. n = 2 [1.4%]). Three women who received salbutamol + nifedipine had serious side effects including echocardiographic changes, chest pain, and metabolic and lactic acidosis. Conclusion: Salbutamol + nifedipine tocolysis was proven to be more effective than nifedipine only. Although salbutamol + nifedipine had increased temporary side effects, most were nonsevere and managed in-flight

Air medical retrieval of central Australian women in labor: A retrospective observational study

Objective: The aim of this study was to describe the characteristics and outcomes of remote-dwelling pregnant women with threatened labor referred for air medical retrieval to a regional birthing center as well as factors associated with birth within 48 hours. Methods: This was a retrospective observational study of all pregnant women in the remote Central Australian region referred to the Medical Retrieval Consultation and Coordination Centre for labor \u3e 23 weeks’ gestation between February 12, 2018, and February 12, 2020. Univariate and multivariate statistical analyses were performed. Results: There were 116 women referred for retrieval for labor. There were no births during transport, and less than half of the cases resulted in birth within 48 hours of retrieval. Tocolysis was frequently used. Predictors of birth within 48 hours were cervical dilatation ≥ 5 cm, preterm gestational age, and ruptured membranes in the univariate analysis. Nearly one third of this cohort required intervention or had complications during birth. Conclusion: Birth during transport for threatened labor did not occur in this cohort, and more than half of the retrievals did not result in birth within 48 hours; however, the high risk of birth complications may offset any benefit of avoiding air medical transport from remote regions. Retrieval clinicians should consider urgent transfer in cases of ruptured membranes, cervical dilatation of 5 cm or more, or gestational age less than 37 weeks
