Aeromedical Retrieval for Stroke in Australia.

INTRODUCTION: Rural, remote, and Indigenous stroke patients have worse stroke outcomes than urban Australians. This may be due to lack of timely access to expert facilities. OBJECTIVES: We aimed to describe the characteristics of patients who underwent aeromedical retrieval for stroke, estimate transfer times, and investigate if flight paths corresponded with the locations of stroke units (SUs) throughout Australia. METHODS: Prospective review of routinely collected Royal Flying Doctor Service (RFDS) data. Patients who underwent an RFDS aeromedical retrieval for stroke, July 2014-June 2018 (ICD-10 codes: I60-I69), were included. To define the locations of SUs throughout Australia, we accessed data from the 2017 National Stroke Audit. The main outcome measures included determining the characteristics of patients with an in-flight diagnosis of stroke, their subsequent pickup and transfer locations, and corresponding SU and imaging capacity. RESULTS: The RFDS conducted 1,773 stroke aeromedical retrievals, consisting of 1,028 (58%) male and 1,481 (83.5%) non-Indigenous and 292 (16.5%) Indigenous patients. Indigenous patients were a decade younger, 56.0 (interquartile range [IQR] 45.0-64.0), than non-Indigenous patients, 66.0 (IQR 54.0-76.0). The most common diagnosis was "stroke not specified," reflecting retrieval locations without imaging capability. The estimated median time for aeromedical retrieval was 238 min (95% confidence interval: 231-244). Patients were more likely to be transferred to an area with SU and imaging capability (both p < 0.0001). CONCLUSION: Stroke patients living in rural areas were younger than those living in major cities (75 years, Stroke Audit Data), with aeromedically retrieved Indigenous patients being a decade younger than non-Indigenous patients. The current transfer times are largely outside the time windows for reperfusion methods. Future research should aim to facilitate more timely diagnosis and treatment of stroke.

Aeromedical retrievals for gastrointestinal disorders in rural and remote Australia: the need for improved access to specialist advice.

The Royal Flying Doctor Service (RFDS) provides medical care to populations without access to traditional health-care services. From 2014 to 2018 the RFDS conducted 6007 (≈1201/year) aeromedical retrievals for gastrointestinal (GI) disorders. More detailed research is needed to determine specific GI disorders that contributed to this caseload, and in particular inform whether the establishment of a GI specialist service is justified.

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 non-Royal 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%) non-Indigenous 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.

Royal Flying Doctor Service Coronavirus Disease 2019 Activity and Surge Modeling in Australia.

Objective: There is a coronavirus disease 2019 (COVID-19) pandemic. We aimed to describe the characteristics of patients transported by the Royal Flying Doctor Service (RFDS) for confirmed or suspected COVID-19 and to investigate the surge capacity of and operational implications for the RFDS in dealing with COVID-19. Methods: This was a prospective cohort study. To determine the characteristics of patients transported for confirmed or suspected COVID-19, we included patient data from February 2, 2020, to May 6, 2020. To investigate the surge capacity and operational implications for the RFDS in dealing with COVID-19, we built and validated an interactive operations area-level discrete event simulation decision support model underpinned by RFDS air medical activity data from 2015 to 2019 (4 years). This model was subsequently used in a factorial in silico experiment to systematically investigate both the supply of RFDS air medical services and the increased rates of demand for these services for diseases of the respiratory system. Results: The RFDS conducted 291 patient episodes of care for confirmed or suspected COVID-19. This included 288 separate patients, including 136 men and 119 women (sex missing = 33), with a median age of 62.0 years (interquartile range, 43.5-74.9 years). The simulation decision support model we developed is capable of providing dynamic and real-time support for RFDS decision makers in understanding the system's performance under uncertain COVID-19 demand. With increased COVID-19-related demand, the ability of the RFDS to cope will be driven by the number of aircraft available. The simulation model provided each aviation section with estimated numbers of aircraft required to meet a range of anticipated demands. Conclusion: Despite the lack of certainty in the actual level of COVID-19-related demand for RFDS services, modeling demonstrates that the robustness of meeting such demand increases with the number of operational and medically staffed aircraft.

Mental Health Crises in Rural and Remote Australia: An Assessment of Direct Medical Costs of Air Medical Retrievals and the Implications for the Societal Burden.

OBJECTIVE: Adequate mental health service provision in rural and remote Australian communities is problematic because of the tyranny of distance. The Royal Flying Doctor Service provides air medical retrieval for people in rural and remote areas. The economic impact on both the Royal Flying Doctor Service and the public hospital system for mental health-related air medical retrievals is unknown. We aimed to estimate the direct medical costs associated with air medical retrievals and subsequent hospitalizations for mental and behavioral disorders for the 2017 calendar year. METHODS: All patients with a primary working diagnosis of International Statistical Classification of Diseases and Related Health Problems, 10th Version, Australian Modification F00 to F99 (mental and behavioral disorders) who underwent an air medical retrieval were included in this cost analysis. International Statistical Classification of Diseases and Related Health Problems, 10th Edition, Australian Modification codes were mapped to Australian Refined Diagnosis Related Group codes, with hospital costs applied from the National Hospital Cost Data Collection (2016/2017). All costs are reported in 2017 Australian dollars (AUDs). RESULTS: One hundred twenty-two primary evacuations and 926 interhospital transfers occurred with an in-flight diagnosis of F00 to F99, most commonly psychotic disorders, including schizophrenia and schizotypal disorders. The total direct medical costs were estimated to be AUD $20,070,527. Costs for primary evacuations accounted for 13% (AUD $2,611,260), with the majority of this associated with the subsequent hospital admission (AUD $1,770,139). Similarly, the majority of the costs associated with interhospital transfers (total costs = AUD $17,459,267) were also related to hospital costs (AUD $13,569,187). CONCLUSION: Direct medical costs associated with air medical retrievals for people experiencing a mental health crisis are substantial. The majority of costs are associated with hospital admission and treatment; however, the indirect (loss of productivity) and intangible (quality of life) costs are likely to be far greater.

Mental Health Care for Rural and Remote Australians During the Coronavirus Disease 2019 Pandemic.

The aims of this article are to comment on pre-coronavirus disease 2019 (COVID-19) mental health activity in rural and remote Australia, including related air medical retrievals; to discuss how the current pandemic is likely to impact on this vulnerable population's mental health; and to provide potential solutions. The COVID-19 pandemic has resulted in significant air medical activity from rural and remote Australia. COVID-19 and the necessary public health and socioeconomic interventions are likely to significantly compound mental health problems for both the general public and the mental health workforce servicing rural and remote communities. However, the COVID-19 crisis provides a window of opportunity to develop, support, and build novel and sustainable solutions to the chronic mental health service vulnerabilities in rural and remote areas in Australia and other countries.

Aeromedical retrievals of people for mental health care and the low level of clinical support in rural and remote Australia.

OBJECTIVES: To characterise the people retrieved by the Royal Flying Doctor Service (RFDS) for treatment of mental and behavioural disorders, and to assess mental health care provision in rural and remote areas. DESIGN: Prospective review of routinely collected RFDS and Health Direct data. SETTING, PARTICIPANTS: RFDS aeromedical retrievals of patients from anywhere in Australia except Tasmania during 1 July 2014 - 30 June 2017 for the treatment of mental or behavioural disorders. MAIN OUTCOME MEASURES: Retrievals by ICD-10 mental and behavioural disorder diagnoses. RESULTS: 2257 patients were retrieved by the RFDS for treatment of mental or behavioural disorders, including 1394 males (62%) and 863 females (38%); 60% of patients were under 40 years of age, 35% identified as Indigenous Australians. The most frequent mental and behavioural disorders were schizophrenia (227 retrievals, 16.5% of retrievals with ICD diagnoses), bipolar affective disorder (185, 13.5%), and depressive episodes (153, 11.2%). Psychoactive substance misuse triggered 194 retrievals (14.2%), including misuse of multiple drugs (85, 6.2%), alcohol (61, 4.5%), and cannabinoids (25, 1.8%). The mean age of patients retrieved for treatment of substance misuse (29.6 years; SD, 11.6 years) was lower than for retrieved patients overall (37.0 years; SD, 19.3 years); 38 of 194 patients retrieved after psychoactive substance misuse (19.6%) were under 19 years of age. Most retrieval sites were rural and remote communities with low levels of mental health care support. CONCLUSION: Mental and behavioural disorders are an important problem in rural and remote communities, and acute presentations trigger a considerable number of RFDS retrievals.

A nurse-led structured education program improves self-management skills and reduces hospital readmissions in patients with chronic heart failure: a randomized and controlled trial in China.

INTRODUCTION: Patient self-management skills are an important part of heart failure (HF) management. However, there is a lack of knowledge about the effectiveness of nurse-led education on patient self-management and the associated clinical outcomes of rural Chinese patients with chronic heart failure (CHF). As such, this study was designed to evaluate the impact of a nurse-led education program on patient self-management and hospital readmissions in rural Chinese patients with CHF. METHODS: Ninety-six patients in the eastern Chinese province of Shandong with CHF were randomly divided into intervention and control groups. A structured education program was delivered to the intervention group during hospitalization and after discharge. Control group patients were managed as per clinical guidelines without structured education. Medication adherence, dietary modifications, social support, and symptom control were assessed 12 months after the educational intervention. RESULTS: The mean score of medication adherence, dietary modifications, social support and symptom control in the intervention group was higher than in the control group at the end of the study (p<0.01). The readmission rates for HF in the intervention and control group were 10.4% and 27.1%, respectively (p=0.036). CONCLUSIONS: This study has demonstrated that a structured education program was associated with a significant improvement in medication adherence, dietary modifications, social support, and symptom control in rural CHF patients. Furthermore, this program was associated with a significant reduction in hospital readmission. This study indicates that implementation of a nurse-led education program improves self-management and clinical outcomes of rural CHF patients, who may not have regular access to cardiac management services as per metropolitan populations.

The feasibility and acceptability of a population-level antenatal risk factor survey: Cross-sectional pilot study.

AIM: Australian data on the prevalence and distribution of antenatal risk factors are scarce. This study aimed to investigate (i) the feasibility and acceptability of an antenatal risk factor survey collected in public settings and (ii) whether the survey risk factors co-occur with more sensitive risk factors that are privately asked by clinicians. METHODS: Design and setting: study-designed survey linked with clinician-collected risk factors. PARTICIPANTS: pregnant women attending antenatal clinics at two Victorian hospitals. MEASURES: (i) study-designed survey: young pregnancy, no support, poor/fair/good general health, anxious mood, not finishing high school, no income, long-term illness, living without another adult, not employed, never had a job and proxy poverty measures; (ii) Clinician-collected data: smoking, alcohol/marijuana/drug use, domestic violence, social issues, history of mental health problems and depression symptoms. ANALYSES: (i) feasibility and acceptability were assessed through survey completion. Each item was assessed for whether they discriminated risk; dichotomised into risk versus no risk; with a total count calculated. (ii) Co-occurrence was assessed by examining how the risk factor count agreed with clinician-collected items. RESULTS: One hundred and sixty-six of 186 (89%) eligible women completed the survey; 139 of 166 (84%) consented to linking clinician-collected data. The high response and zero missing data demonstrated feasibility and acceptability. Of women with linked data, 92 of 139 (66%) had ≥1 survey risk factor and 30 of 139 (22%) had ≥3; 36 of 139 (26%) had at least one co-occurring clinician-collected risk factor. CONCLUSIONS: This survey provides a simple, rapid approach to gathering antenatal risk data publicly. It may be a helpful addition to clinicians' standard history collection.

Aeromedical retrieval for suspected appendicitis in rural and remote paediatric patients.

INTRODUCTION: The aim of this paper was to describe the characteristics of paediatric patients who underwent an aeromedical retrieval within Australia (gender and Indigenous status) for suspected appendicitis between 1 July 2014 and 30 June 2018 (4 years). By understanding these trends, we hope to further justify the need for point-of-care ultrasound training for clinicians working in rural and remote Australia. METHOD: Participants included Royal Flying Doctor Service (RFDS) patients aged 0-18 years (inclusive) who underwent an aeromedical retrieval for suspected appendicitis within Australia. Data were collected and coded on each patient's inflight working diagnosis, using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) coding method. A combination of descriptive statistics and chi-square analyses was used in data analysis, with significance considered at <0.05. RESULTS: There were 384 children with a working diagnosis of suspected appendicitis, including 191 (49.7%) males and 193 (50.3%) females, with 133 (34.6%) patients identifying as Aboriginal and/or Torres Strait Islander (hereafter referred to as Indigenous) Australians. The aeromedical retrievals were from rural and remote locations to inner-regional or metropolitan hospitals, with an average distance flown of 339.0 (SD = 206.4) kilometres. The RFDS most frequently retrieved for acute appendicitis (n = 159; 41.4%), acute abdominal pain (n = 127; 33.1%), and unspecified appendicitis (n = 84; 21.9%). There were non-significant (P = 0.9) diagnostic differences between genders. Non-Indigenous patients were overrepresented, compared with Indigenous patients, in relation to a transfer with a diagnosis of acute appendicitis (P = <0.01), whereas Indigenous patients were overrepresented, compared with non-Indigenous patients, in relation to transfers with diagnoses of acute abdomen pain and unspecified appendicitis (P = <0.01). CONCLUSION: A significant number of paediatric patients are aeromedically retrieved from rural and remote locations with a diagnosis of appendicitis or acute abdominal pain. Future research should consider whether training in abdominal point-of-care ultrasound reduces retrievals.

A brief survey to identify pregnant women experiencing increased psychosocial and socioeconomic risk.

PROBLEM: Identifying pregnant women whose children are at risk of poorer development in a rapid, acceptable and feasible way. BACKGROUND: A range of antenatal psychosocial and socioeconomic risk factors adversely impact children's health, behaviour and cognition. AIM: Investigate whether a brief, waiting room survey of risk factors identifies women experiencing increased antenatal psychosocial and socioeconomic risk when asked in a private, in-home interview. METHODS: Brief 10-item survey (including age, social support, health, smoking, stress/anxious mood, education, household income, employment) collected from pregnant women attending 10 Australian public birthing hospitals, used to determine eligibility (at least 2 adverse items) for the "right@home" trial. 735 eligible women completed a private, in-home interview (including mental health, wellbeing, substance use, domestic violence, housing problems). Regression models tested for dose-response trends between the survey risk factor count and interview measures. FINDINGS: 38%, 31%, 15% and 16% of women reported a survey count of 2, 3, 4 and 5 or more adverse risk factors, respectively. Dose-response relationships were evident between the survey count and interview measures, e.g. of women with a survey count of 2, 8% reported ever having a drug problem, 4% experienced domestic violence in the last year and 10% experienced housing problems, contrasting with 31%, 31% and 26%, respectively, for women reporting a survey count of 5 or more. DISCUSSION/CONCLUSIONS: A brief, waiting room survey of psychosocial and socioeconomic risk factors concurs with a private antenatal risk factor interview, and could help health professionals quickly identify which women would benefit from more support.

Nurse Home Visiting for Families Experiencing Adversity: A Randomized Trial.

OBJECTIVES: Nurse home visiting (NHV) may redress inequities in children's health and development evident by school entry. We tested the effectiveness of an Australian NHV program (right@home), offered to pregnant women experiencing adversity, hypothesizing improvements in (1) parent care, (2) responsivity, and (3) the home learning environment at child age 2 years. METHODS: A randomized controlled trial of NHV delivered via universal child and family health services was conducted. Pregnant women experiencing adversity (≥2 of 10 risk factors) with sufficient English proficiency were recruited from antenatal clinics at 10 hospitals across 2 states. The intervention comprised 25 nurse visits to child age 2 years. Researchers blinded to randomization assessed 13 primary outcomes, including Home Observation of the Environment (HOME) Inventory (6 subscales) and 25 secondary outcomes. REULTS: Of 1427 eligible women, 722 (50.6%) were randomly assigned; 306 of 363 (84%) women in the intervention and 290 of 359 (81%) women in the control group provided 2-year data. Compared with women in the control group, those in the intervention reported more regular child bedtimes (adjusted odds ratio 1.76; 95% confidence interval [CI] 1.25 to 2.48), increased safety (adjusted mean difference [AMD] 0.22; 95% CI 0.07 to 0.37), increased warm parenting (AMD 0.09; 95% CI 0.02 to 0.16), less hostile parenting (reverse scored; AMD 0.29; 95% CI 0.16 to 0.41), increased HOME parental involvement (AMD 0.26; 95% CI 0.14 to 0.38), and increased HOME variety in experience (AMD 0.20; 95% CI 0.07 to 0.34). CONCLUSIONS: The right@home program improved parenting and home environment determinants of children's health and development. With replicability possible at scale, it could be integrated into Australian child and family health services or trialed in countries with similar child health services.

'right@home': a randomised controlled trial of sustained nurse home visiting from pregnancy to child age 2†years, versus usual care, to improve parent care, parent responsivity and the home learning environment at 2†years.

INTRODUCTION: By the time children start school, inequities in learning, development and health outcomes are already evident. Sustained nurse home visiting (SNHV) offers a potential platform for families experiencing adversity, who often have limited access to services. While SNHV programmes have been growing in popularity in Australia and internationally, it is not known whether they can improve children's learning and development when offered via the Australian service system. The right@home trial aims to investigate the effectiveness of an SNHV programme, offered to women from pregnancy to child age 2 years, in improving parent care of and responsivity to the child, and the home learning environment. METHODS AND ANALYSIS: Pregnant Australian women (n=722) are identified after completing a screening survey of 10 factors known to predict children's learning and development (eg, young pregnancy, poor mental or physical health, lack of support). Consenting women-surveyed while attending clinics at 10 hospitals in Victoria and Tasmania-are enrolled if they report having 2 or more risk factors. The intervention comprises 25 home visits from pregnancy to 2 years, focusing on parent care of the child, responsivity to the child and providing a good quality home learning environment. The standard, universal, Australian child and family health service provides the comparator (control). Primary outcome measures include a combination of parent-reported and objective assessments of children's sleep, safety, nutrition, parenting styles and the home learning environment, including the Home Observation of the Environment Inventory and items adapted from the Longitudinal Study of Australian Children. ETHICS AND DISSEMINATION: This study is approved by the Royal Children's Hospital Human Research Ethics Committees (HREC 32296) and site-specific HRECs. The investigators and sponsor will communicate the trial results to stakeholders, participants, healthcare professionals, the public and other relevant groups via presentations and publications. TRIAL REGISTRATION NUMBER: ISRCTN89962120, pre-results.
