Predictive and protective factors for failing first pass intubation in prehospital rapid sequence intubation: an aetiology and risk systematic review with meta-analysis.

BACKGROUND: Prehospital rapid sequence intubation first pass success rates vary between 59% and 98%. Patient morbidity is associated with repeat intubation attempts. Understanding what influences first pass success can guide improvements in practice. We performed an aetiology and risk systematic review to answer the research question 'what factors are associated with success or failure at first attempt laryngoscopy in prehospital rapid sequence intubation?'. METHODS: MEDLINE, EMBASE, CINAHL, and Cochrane Library were searched on March 3, 2023 for studies examining first pass success rates for rapid sequence intubation of prehospital live patients. Screening was performed via Covidence, and data synthesised by meta-analysis. The review was registered with PROSPERO and performed and reported as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Reasonable evidence was discovered for predictive and protective factors for failure of first pass intubation. Predictive factors included age younger than 1 yr, the presence of blood or fluid in the airway, restricted jaw or neck movement, trauma patients, nighttime procedures, chronic or acute distortions of normal face/upper airway anatomy, and equipment issues. Protective factors included an experienced intubator, adequate training, use of certain videolaryngoscopes, elevating the patient on a stretcher in an inclined position, use of a bougie, and laryngeal manoeuvres. CONCLUSIONS: Managing bloody airways, positioning well, using videolaryngoscopes with bougies, and appropriate training should be further explored as opportunities for prehospital services to increase first pass success. Heterogeneity of studies limits stronger conclusions. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42022353609).

A Guided Comparative Analysis of Fatigue Frameworks in Australasian Ambulance Services.

OBJECTIVE: Paramedics work in a complex, unpredictable environment, subject to many external stressors including critically unwell patients, dangerous driving conditions, and prolonged shift work. Paramedic fatigue from these and other occupational demands is well documented. Ambulance services attempt to safeguard paramedics from fatigue using internal policies or procedures - a type of Fatigue Risk Management Systems (FRMSs). This study reviews ambulance service fatigue frameworks to understand the current situation in fatigue management in paramedicine, and to identify fatigue monitoring tools, strategies, and other components of these frameworks that are designed to protect personnel. METHODS: This study involved a qualitative document thematic content analysis. All eleven statutory ambulance services across Australia, New Zealand, and Papua New Guinea, represented by the Council of Ambulance Authorities, were contacted and invited to participate. Fatigue frameworks were collated and entered into NVivo where data extraction occurred through three a priori areas (fatigue, fatigue mitigation tools & fatigue management). RESULTS: Nine of the eleven ambulance services provided fatigue documentation, with one declining to participate, and one did not respond to invitations. Through thematic analysis and abstraction, seven themes were identified: fatigue definition, consequences of fatigue, sources of fatigue, signs and symptoms of fatigue, fatigue-related incidents, fatigue monitoring tools, and fatigue mitigation. There was also poor alignment between provided frameworks and established FRMSs components. CONCLUSION: Our findings provide an initial insight into existing ambulance service fatigue frameworks across Australia, New Zealand, and Papua New Guinea. The many inconsistencies in frameworks between ambulance services highlight an opportunity to develop a more consistent, collaborative approach that follows evidence-based FRMSs guidelines.

Characteristics and Outcomes of Patients Referred to a General Practitioner by Victorian Paramedics.

OBJECTIVE: Many patients who are attended by paramedics do not require conveyance to an emergency department (ED). Our study focuses on comparing the characteristics and outcomes of patients who were advised to follow up with a general practitioner (GP) by an attending paramedic with those of patients who were discharged at scene or transported to hospital. METHODS: This was a retrospective data linkage cohort study of ambulance, ED, hospital admission, and death records for all adults attended by paramedics in Victoria, Australia between the 1st of January 2015 and 30th of June 2019. Patients were excluded if they presented in cardiac arrest, resided in a residential aged care facility, or were receiving palliative care services. Outcomes of interest included reattendance by ambulance, ED presentation; and, a high acuity outcome which we defined as a patient who (1) presented to ED and received an Australasian Triage Scale of category 1 (Resuscitation) or 2 (Emergency) AND was admitted to a ward OR (2) was admitted to an Intensive Care Unit, Coronary Care Unit or Catheter laboratory (regardless of triage category) OR (3) died. Outcomes of interest were considered within 48-h of initial EMS attendance. RESULTS: A total of 1,777,950 cases were included in the study of which 3.1% were referred to a GP, 9.0% were discharged at scene without a follow-up recommendation, and 87.9% were transported to hospital. Patients referred to a GP were more likely than those discharged at scene to subsequently present to an ED within 48 h of their attendance (5.3% vs 3.8%). However, GP referral was not associated with any change to high acuity outcome (0.3% vs 0.2%) or ambulance reattendance (6.0% vs 6.0%) compared to discharge at scene. The only factors that were associated with ambulance reattendance, ED presentation, and a high acuity outcome were male gender and elevated temperature. CONCLUSIONS: Despite increasing low and medium-acuity casework in this EMS system, paramedic referral to a GP is not common practice. Referring a patient to a GP did not reduce the likelihood of patients experiencing a high acuity outcome or recalling an ambulance within 48 h, suggesting opportunity exists to refine paramedic to GP referral practices.

Identifying the essential elements to inform the development of a research agenda for Paramedicine in Ireland: a Delphi Study.

BACKGROUND: Paramedicine is a dynamic profession which has evolved from a "treat and transport" service into a complex network of health professionals working in a diverse range of clinical roles. Research is challenging in the paramedicine context, and internationally, research capacity and culture has developed slowly. International examples of research agendas and strategies in paramedicine exist, however, research priorities have not previously been identified in Ireland. METHODS: This study was a three round electronic modified Delphi design which aimed to establish the key aspects of the research priorities via end-user consensus. Participants included interested stakeholders involved in prehospital care or research in Ireland. The first round questionnaire consisted of open-ended questions with results coded and developed into themes for the closed-ended questions used in the second and third round questionnaires. A consensus level of 70% was set a priori for second and third rounds. RESULTS: Research Priorities that reached consensus included Staff Wellbeing, Education and Professionalism and Acute Medical Conditions. Respondents indicated that these three areas should be a priority in the next 2 years. Education, Staffing and Leadership were imperative Key Resources that required change. Education was a Key Processes change deemed imperative to allow the future research to occur. Outcomes that should be included in the future research strategy were Patient Outcomes, Practitioner Development, Practitioner Wellbeing, Alternate Pathways, Evidence-based Practice and Staff Satisfaction. CONCLUSION: The results of this study are similar to previously published international studies, with some key differences. There was a greater emphasis on Education and Practitioner Wellbeing with the latter possibly attributed to the timing of the research in relation to the COVID-19 pandemic. The disseminated findings of this study should inform sustainable funding models to aid the development of paramedicine research in Ireland.

Developing a consensus-based definition of out-of-hospital clinical deterioration: A Delphi study.

BACKGROUND: Clinical deterioration is a time-critical medical emergency requiring rapid recognition and intervention. Deteriorating patients are seen across various healthcare settings, including the out-of-hospital (OOH) environment. OOH care is an evolving area of medicine where decisions are made regarding priority and timing of clinical interventions, ongoing management, and transport to appropriate care. To date, the literature lacks a standardised definition of OOH clinical deterioration. OBJECTIVE: The objective of this study was to create a consensus-based definition of OOH clinical deterioration informed by emergency medicine health professionals. METHODS: A Delphi study consisting three rounds was conducted electronically between June 2020 and January 2021. The expert panel consisted of 30 clinicians, including emergency physicians and paramedics. RESULTS: A consensus-based definition of OOH clinical deterioration was identified as changes from a patient's baseline physiological status resulting in their condition worsening. These changes primarily take the form of measurable vital signs and assessable symptoms but should be evaluated in conjunction with the history of events and pertinent risk factors. Clinicians should be suspicious that a patient could deteriorate when changes occur in one or more of the following vital signs: respiratory rate, heart rate, blood pressure, Glasgow Coma Scale, oxygen saturation, electrocardiogram, and skin colour. Almost all participants (92%) indicated an early warning system would be helpful to assist timely recognition of deteriorating patients. CONCLUSION: The creation of a consensus-based definition of OOH clinical deterioration can serve as a starting point for the development and validation of OOH-specific early warning systems. Moreover, a standardised definition allows meaningful comparisons to be made across health services and ensures consistency in future research. This study has shown recognition of OOH clinical deterioration to be a complex issue requiring further research. Improving our understanding of key factors contributing to deterioration can assist timely recognition and intervention, potentially reducing unnecessary morbidity and mortality.

Pediatric Out-of-Hospital Cardiac Arrests: An Epidemiological Study.

OBJECTIVE: To identify the epidemiological patterns of pediatric out-of-hospital cardiac arrests (OHCA) in Queensland, Australia and to investigate associations between patient variables and prehospital outcome. METHODS: Included were pediatric (>4 days-18 years) OHCA patients attended by paramedics in the state of Queensland (Australia) between January 2009 and December 2019. Patient and arrest characteristics were described. Factors associated with return of spontaneous circulation (ROSC) on hospital arrival were investigated. RESULTS: A total of 1,612 pediatric patients were included; 611 were deceased prior to paramedic arrival and 1,001 received resuscitation attempts by paramedics. Approximately one quarter (26.8%) of resuscitation-attempted patients achieved ROSC on hospital arrival. Most arrests (49.7%) were due to medical causes. Arrests due to trauma had the lowest rate of ROSC on hospital arrival (9.6%), whereas those due to drug overdose had the highest rate (40%). Patients in rural areas had a lower rate of ROSC on hospital arrival than those in metropolitan areas (20.7% vs 32.5%, p < 0.001). The median response interval to all OHCA patients was 8 minutes. Trauma was considerably more prevalent in rural areas than in metropolitan areas, while all other etiologies were comparable. Older pediatric age groups had higher rates of ROSC on hospital arrival than infants, particularly early adolescents (39.4% vs. 14.9%, p = 0.001). Etiology, age, bystander witness, shockable initial rhythm, and geographic locality factors were independently associated with ROSC on hospital arrival. CONCLUSIONS: Approximately a quarter of pediatric prehospital OHCA achieved ROSC on hospital arrival. Prehospital outcome differs according to patient cohort and is associated with diverse patient demographic variables.

The Effect of Commencing Rotating Shift Work on Diet and Body Composition Changes in Graduate Paramedics: A Longitudinal Mixed Methods Study.

Objectives: Diet quality often changes as shift workers adjust to atypical work schedules, however, limited research exists examining the early effects of starting rotating shift work on diet and body composition. This study explored dietary behavior changes occurring in graduate paramedics during the first year of exposure to rotating shift work, and investigated dietary intake, diet quality and anthropometric changes over two years.Methods: Participants from a graduate paramedic cohort in Melbourne, Australia were approached after two years of shift work for study inclusion. Using a mixed method study approach, the qualitative component comprised individual in-depth interviews to explore perceived dietary behavior changes experienced over the first year of shift work. Interview transcripts were thematically analyzed and guided by the COM-B model (capability, opportunity, motivation, and behavior) and theoretical domains framework (TDF). Diet quality and dietary intake were quantitatively assessed by the Australian Eating SurveyTM at baseline, one year, and two years, along with body weight, waist circumference, and body mass index (BMI) to monitor changes.Results: Eighteen participants were included in the study. From the interviews, participants reported: 1. food choices are driven by wanting to fit in with coworker food habits, 2. food choices and mealtimes are unpredictable and 3. paramedics try to make healthy food choices but give in to less healthy options. While daily energy intake and diet quality scores did not differ in the first two years of shift work, daily energy from takeaway foods significantly increased (mean difference (MD): 2.96% EI; 95% CI: 0.44 - 5.48; p = 0.017) and increases in weight (MD: 2.96 kg; 95% CI: 0.89-5.04; p = 0.003), BMI (MD: 1.07 kg/m2; 95% CI: 0.26 - 1.87; p = 0.006) and waist circumference (MD: 5.07 cm; 95% CI: 1.25-8.89; p = 0.006) were also evident at two years.Conclusions: This study contributes new information on dietary changes and the current early trajectory of unintentional weight gain and takeaway reliance occurring within a graduate paramedic cohort over two years of shift work. To reduce the unintended metabolic consequences commonly observed with rotating shift schedules, workplaces could improve access to healthier food options and enable behavioral support/education to address nutrition-related health risks.

Lumbar Flexion During Driving: Establishing a Methodology for Characterising Real-Time Posture Data Collected by Innovative Technology.

OBJECTIVE: To determine a methodology for the analysis of real-time driving posture data in the low back pain population. BACKGROUND: The strength of the relationship between driving posture and low back pain is yet to be defined due to the lack of studies in the field using validated and repeatable posture measurement tools. Reliable and validated real-time measurement tools are now available, yet reliable methods of analysis of these data are yet to be established. METHOD: Ten occupational drivers completed a typical work shift while wearing an inertial motion sensor system (dorsaVi ViMove). Real-time lumbar flexion data were extracted, with test-retest reliability of mean lumbar flexion, peak lumbar flexion, and standard deviation of lumbar flexion analysed at different times across a work shift, and in different sections within a drive. RESULTS: Mean lumbar flexion was highly repeatable over numerous drives in one day, with greater test-retest reliability if the first five minutes of driving data were excluded. Peak lumbar flexion had acceptable test-retest reliability over numerous drives in one day, while standard deviation of lumbar flexion was not a repeatable measure. CONCLUSION: Mean lumbar flexion was a reliable outcome for characterising driving posture in drivers with low back pain. Peak lumbar flexion may be used if appropriate to the individual study. Standard deviation of lumbar flexion is not a reliable posture outcome. APPLICATION: This paper provides a reliable methodology for analysis of real-time driving posture data in occupational drivers with low back pain.

Assessment of Cardiometabolic Health, Diet and Physical Activity in Helicopter Rescue Paramedics.

Objective: Shift work is an established risk factor for weight gain, cardiovascular disease, Type II diabetes mellitus, and impaired health-related quality of life (HRQoL). Prolonged exposure to shift work is common in paramedics and other emergency medical service (EMS) providers. Sub-populations of EMS workers may have varying health outcomes when exposed to shift work, but the reasons for this have not been investigated. We sought to describe cardiometabolic health, dietary patterns, physical activity, and health-related quality of life (HRQoL) in a sample of experienced intensive care flight paramedics (ICFPs) working for a Helicopter Emergency Medical Service (HEMS).Methods: Fifteen paramedics (median age 45, IQR 42-48 years) were recruited to undertake a range of health assessments. These included a food frequency questionnaire to assess dietary patterns, sampling of biomarkers to determine cardiometabolic health risk, maximal aerobic capacity assessment via treadmill running and assessment of HRQoL via the SF-36 survey. In an extension of the study protocol, ten of the fifteen participants wore a physical activity monitor for one year.Results: Median (IQR) weight was 79.9 (72.3-89.3) kg, body fat percentage 23.3 (21.9-26.5) %, body mass index (BMI) 25.1 (21.9-27.4) kg.m2, and waist to height ratio 0.48 (0.45-0.54). Dietary analyses showed high discretionary food intake. Biomarkers of cardiometabolic health risk were all within normal range. HRQoL was 86.2/100 for physical health and 85.1/100 for mental health. V̇O2max was 47.0 (43.0-54.6) mL.kg-1.min-1. The ten participants that wore activity monitors completed 11,235 (8334-15,380) steps per day and undertook 50 (12-98) minutes per day/350 (84-686) minutes per week of moderate to vigorous physical activity. The least amount of physical activity was conducted on day shifts.Conclusions: For ICFPs included in this study, HRQoL, cardiometabolic and physical activity outcomes are representative of good health. Although shift work influences the amount of physical activity, ICFPs exceeded minimum recommendations even when rostered to duty. Despite lengthy careers in EMS, ICFPs demonstrate an excellent health profile that is likely due to high physical activity levels and healthy BMI. This information may be useful in guiding health interventions in the wider EMS workforce.

Cardiometabolic, Dietary and Physical Health in Graduate Paramedics during the First 12-Months of Practice - A Longitudinal Study.

Objective: Shift work is an established risk factor for poor health yet is necessary for paramedics to provide continuous care to the public. It is unknown how early into a career shift work may begin to impact health. This study sought to identify changes in cardiometabolic health, diet, aerobic capacity, physical activity and health-related quality of life (HRQoL) in graduate paramedics during the first 12-months of their career.Methods: Fifty-six paramedics with no history of regular shift work (28 female, 28 male; median age 24.5, IQR 23-26 years) were recruited for this study. Dietary patterns (food frequency questionnaires) and HRQoL (36-Item Short Form Questionnaire) were assessed at baseline, 6- and 12-months. Body weight, body mass index (BMI) and blood samples (fasting lipids, glucose, insulin and C-reactive protein) were measured at baseline and 12-months to ascertain cardiometabolic health risk. A subset of participants (n = 19; 10 female, 9 male) wore a physical activity monitor for 12 months and completed baseline and 12-month maximal aerobic capacity assessments (V̇O2max).Results: Body weight and BMI decreased in males and increased in females (-0.7% versus 1.7%, p = 0.02). HRQoL and dietary intake did not change over 12-months, except for a small decrease in fat intake (-1%). Consumption of core/healthy foods was lower than recommended at all timepoints. Biomarkers of cardiometabolic health were within normal range and did not change over 12-months, excepting insulin where a small non-significant increase was seen (+0.5 mIU/L, p = 0.61). Baseline V̇O2max was 41.4 (37.1-49.1) ml.kg-1.min-1, with no change noted at 12-months. Comparison of quarterly physical activity data showed no difference in steps per day (p = 0.47) or moderate to vigorous physical activity (MVPA, p = 0.92) across the 12-months. Paramedics completed less MVPA on day shifts compared to rostered days off (-14.68 minutes, p = 0.04).Conclusions: Dietary patterns, HRQoL, cardiometabolic health, aerobic capacity and physical activity levels did not change meaningfully in the first year of practice. Some dietary behaviors and physical activity levels could be improved and may mitigate health effects of exposure to shift work. Long-term follow-up of this group may aid in developing programs to enhance health for paramedics and other health workers.

Describing Frequencies of Lower-Limb Apophyseal Injuries in Children and Adolescents: A Systematic Review.

OBJECTIVE: To describe the frequency with which children are affected by lower-limb apophyseal injuries, and subgroups at greater risk. DESIGN: Systematic review. SETTING: N/A. PARTICIPANTS: N/A. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Systematic review of Medline OVID, PsycINFO, Cinahl, and PubMed from inception until February 21st, 2020. Articles reporting prevalence and/or incidence of an apophyseal injury (eg, calcaneal apophysitis) or its eponym (Severs or Sever disease). Per person data relating to the incidence or prevalence. Subgroup comparisons were made between sex groups and between activity participant groups. RESULTS: There was wide variation in measurement approaches and follow-up timeframes with the majority of studies reporting on traction apophysitis of the tibial tubercle (Osgood-Schlatter disease). This condition had a point prevalence of 10% in the general population of children between the ages of 12 and 15 years, whereas the lifetime incidence has been reported as 13%. Point prevalence was higher among those who participated in sport compared with those who did not {relative risk [95% confidence interval (CI): 1.98 (1.31-2.99)]}, whereas lifetime incidence was higher among those who participated in sport at the age of 13 years compared with those who did not [relative risk (95% CI): 4.63 (2.31-9.26)]. Other apophyseal injuries did not report enough data to permit comparisons. CONCLUSION: Sports participation is likely to substantially increase the frequency of traction apophysitis of the tibial tubercle. Further research is required with standardized approaches to compare frequencies between different apophyseal injuries and subgroups of interest.

The physiological demands of helicopter winch rescue in water and over land.

Physically demanding water and over land winch rescues are critical tasks for helicopter paramedics. To assess the physiological demands of winch rescue, 14 intensive care flight paramedics (12 male, 2 female, mean (±SD) age 44.3 (±5.4) years, experience 7.1 (±5.2) years) completed land and water-based task simulations. For the land task, VO2 was 41.7 (±4.5) mL kg-1 min-1, or 86 (±11) % of VO2peak. Task duration was 7.0 (±3.6) min, or 53 (±27) % of maximal acceptable work duration (MAWD) (13.2 (±9.0) min). For the water task, VO2 was 36.7 (±4.4) mL kg-1 min-1, (81 (±12) % of VO2peak). Water task duration was 10.2 (±1.1) min, or 47.6 (±4.8) % of calculated MAWD (21.0 (±15.6) min). These results demonstrate that helicopter rescue paramedics work at very high physiological workloads for moderate durations, and these demands should be considered when developing selection tests and when deploying to rescues, to ensure staff are capable of task performance. Practitioner summary: Paramedics performed helicopter winch rescue task simulations in water and over land. Paramedics worked at 81% of VO2peak for 10.2 min and 86% of VO2peak for 7 min for swim and land tasks respectively. Rescue organisations should consider these demands when selecting and credentialing staff and when deploying to incidents.

The impact of shift work schedules on PVT performance in naturalistic settings: a systematic review.

OBJECTIVE: The Psychomotor Vigilance Test (PVT) is considered the gold standard for detecting sleep loss and circadian misalignment related changes in performance in laboratory and field settings. This short 3-, 5- or 10-min test appraises an individual's sustained vigilant attention on a visual stimulus through reaction time, false starts and performance lapses. The PVT has been widely used as a measure to assess vigilant attention among shift workers, but information evaluating the application and performance of this test in different naturalistic shift work settings is limited. The purpose of this review is to synthesise and evaluate existing literature which has used the PVT to assess and monitor psychomotor performance in response to shift work schedules and rosters performed in real-world settings. METHODS: A systematic search of studies examining PVT performance in response to 24/7 shift work schedules (e.g., day, afternoon, evening and night shifts) performed under naturalistic conditions was conducted. Articles were identified by searching Medline, Embase, CINHAL and PsycINFO databases in April 2020. RESULTS: The search yielded 135 results, of which 16 publications were suitable to be included in this review. Articles were grouped according to when the PVT was applied to a research cohort, which included (a) multiple instances per shift, (b) commencement and cessation of shift and (c) other varying times. CONCLUSIONS: This review suggests PVT performance is typically congruent across studies when the test is applied at generally consistent time intervals. The lack of research concerning the use of the PVT during extended duty shifts (e.g., shifts and on call work > 30 h) is an area for future research.

Sitting Posture During Occupational Driving Causes Low Back Pain; Evidence-Based Position or Dogma? A Systematic Review.

OBJECTIVE: In this review, we determine if there is evidence to demonstrate a relationship between occupational driving posture and low back pain. BACKGROUND: The burden of low back pain is increasing. An understanding of this relationship is required to enable the development of recommendations for clinicians and policy-makers for the driving industry. METHOD: Five databases were searched up to March 12, 2018. Study quality was assessed using the National Heart, Lung, and Blood Institute's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies, followed by a GRADE analysis to consider the evidence as a whole. A narrative, critical synthesis was completed that considered the methods by which driving posture and low back pain were measured and analyzed. RESULTS: There were 653 articles identified, with seven eligible for review. Four articles identified an association between occupational driving posture and low back pain, yet this was based on the use of measurement tools lacking validity. Although a relationship may exist, the specific driving postures associated with low back pain and the strength of this relationship have not been confirmed. CONCLUSION: Future research needs to employ validated and reliable, real-time qualitative methods for measuring occupational driving posture to advance our understanding of this relationship. APPLICATION: Clinical and policy recommendations regarding driving posture and low back pain should be used with caution, as they are guided by evidence incorporating bias. Future studies are required to confirm the specific postures assumed while occupational driving and their relationship with low back pain, before recommendations can be made.

Health care staff responses to disinvestment-A systematic search and qualitative thematic synthesis.

BACKGROUND: Health care services must deliver high-quality, evidence-based care that represents sound value. Disinvestment is the process of withdrawing resources from any existing health care practices that deliver low gain for their cost and reallocating these toward practices that are more effective, efficient, and cost-effective, thus benefiting patients and the community. PURPOSE: This is the first review to examine the responses of health care staff to disinvestment and investigate the factors that increase the likelihood of these staff accepting disinvestment or reallocation of resources from the health services they provide. METHODS: We conducted a systematic search of five electronic databases using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) framework. A critical appraisal process of the quality of the included studies was performed by two authors. We undertook a thematic synthesis of the qualitative data to develop an overarching narrative. RESULTS: Twelve studies were identified for synthesis and all found that the disinvestment process was challenging and controversial for those health care staff involved. Negative staff reactions to disinvestment identified were anxiety, disempowerment, distrust, and feelings of being dismissed and disrespected. Engagement with disinvestment was observed when staff were invited to participate in a process they considered transparent and in the best interests of the community. PRACTICE RECOMMENDATIONS: Health care staff have a strong professional identity associated with autonomy in their decision making in the provision of health care services. Disinvestment from a service that health care staff can usually choose to provide threatens this identity. Engaging clinical champions to lead change, using rigorous patient outcome data, and transparent decision-making processes may assist health care staff to embrace a new identity as innovators and accept disinvestment in low-value health care.

Comparison of swimming versus running maximal aerobic capacity in helicopter rescue paramedics.

Swimming is a critical task for helicopter rescue paramedics and aerobic capacity is assessed in this occupation to determine job suitability. We evaluated one treadmill-based and one pool-based assessment of maximal aerobic capacity (V̇O2peak) in 14 helicopter rescue paramedics. There was a small absolute difference (p = 0.11, d = 0.46) between V̇O2peak in the swim (45.5 ± 7.8 ml.kg-1.min-1) compared to the run (48.5 ± 5.5 ml.kg-1.min-1), with a moderate relationship noted (r = 0.74, 95% CI [0.35-, 0.91], p = 0.0023). Whilst not interchangeable, run V̇O2peak was a predictor of swim V̇O2peak. Maximal blood lactate was similar (p = 0.93) in swim (13.4 ± 3.8 mmol.L-1) and run (12.2 ± 3.0 mmol.L-1), and maximal heart rate 13% lower (p < 0.0001) in the swim (162 ± 11 bpm) versus the run (186 ± 10 bpm). To estimate swimming V̇O2peak in paramedics a treadmill test is sufficient but does not replace assessment of swimming proficiency. Practitioner Summary: We developed a swim protocol to assess maximal aerobic capacity in helicopter rescue paramedics. Compared to a treadmill-based test, our swim protocol generated 20% lower submaximal V̇O2 and 6% lower V̇O2peak. Although not interchangeable, a treadmill V̇O2peak test is indicative of maximal aerobic capacity in rescue paramedics whilst swimming.

Investigating first-year graduate paramedics' reason for current work location: A cross-sectional, data linkage study.

OBJECTIVE: This study aims to describe the demographic and employment characteristics of first-year graduates from a Victorian-based paramedicine course and investigate factors that influenced their choice in place of practice. DESIGN: Cross-sectional study using data from the Nursing and Allied Health Graduate Outcomes Tracking study. SETTING: Victoria, Australia. PARTICIPANTS: First-year graduates (2019) from the Monash University range of paramedicine programs. MAIN OUTCOME MEASURES: Variables of interest included principal place of practice and the reasons for working in the current location. RESULTS: Over half of the 2018 paramedicine course graduates responded to the 2019 Graduate Outcomes Survey. Nearly all were registered as paramedics (including double registrants as nurses), and over a fifth were from a rural background; however, less than that were working in a rural area. Of those with complete data, the most cited reasons for current work location were 'spouse/partner's employment or career', 'opportunity for career advancement' and 'scope of practice within the role'. CONCLUSION: This study provides important insight into the factors associated with rural practice location amongst paramedicine graduates, specifically rural origin or personal, lifestyle and professional influences. The study adds to the sparse literature about paramedic practice location decision-making and highlights the need for further systematic longitudinal research examining the 'where' and 'why'.

Quantifying Lumbar Movement Patterns of Allied Health Professionals in an Australian Health Care Facility.

Health professionals responsible for return to work plans have little data about allied health movement to guide recommendations following lower back injury. This study aimed to quantify the lumbar movement patterns of allied health professionals within a health care facility throughout a normal workday. An observational case study was undertaken at a public health care facility with 122 allied health professionals. The lumbar movements were recorded with the ViMove together with pain scale measurement. The mean (SD) recording time for allied health was 7.7 (0.7) hours. A mean (SD) 3 (1.4) hours total were spent in standing, 3.8 (1.7) hours in sitting, and 0.8 (0.4) hours in locomotion. Forty-nine flexions were recorded on average per session, most identified as short term (<30 s) within low range (0°-20°). Lumbar movement patterns differed among professions. Thirty-seven (31%) participants reported a history of lower back injury, and 57 (47%) reported low back pain at the end of their workday. This study provides an insight into allied health professionals' back movement in a hospital or community-based health care setting. These data may inform those who make return to work recommendations or provide rehabilitation services for allied health professionals working with a lower back injury.

Students as patients: A systematic review of peer simulation in health care professional education.

CONTEXT: Evidence supports the substitution of both clinical placement time and traditional educational activities with simulation-based education (SBE). However, lack of resources can be a barrier to SBE implementation. Peer simulation provides an alternative to simulated patient (SP)-based SBE by educating students to portray patient roles. This diversifies learning experiences for students using SBE and may decrease costs. OBJECTIVES: This study aimed to determine the impact of students portraying the roles of patients in a simulation-based learning environment (peer simulation) on learning outcomes in entry-level health care professional students. METHODS: Seven databases were searched (from inception to 8 May 2019) using terms including 'peer simulation,' 'role-play' and 'simulated/standardised patient.' The studies included described a health care professional student SBE interaction involving peer simulation. Data were extracted by two independent investigators. Study quality was assessed using the Medical Education Research Study Quality Instrument (MERSQI) and Critical Appraisal Skills Programme (CASP). A descriptive analysis was completed and meta-analysis conducted in instances in which outcomes could be pooled. RESULTS: A total of 12 studies met the inclusion criteria. Constructs measured by the studies included communication, empathy, self-efficacy and confidence. Five randomised controlled trials compared peer simulation with the use of SPs and demonstrated greater or equivalent patient empathy gains in peer simulation. Meta-analysis determined no difference in communication capabilities between the two groups. Students perceived peer simulation as comparably valuable and frequently superior to other forms of learning. This review was unable to determine effective design features of peer simulation initiatives. CONCLUSIONS: Students were positive about peer simulation, but there has been limited evaluation of learning outcome attainment. Significant heterogeneity was observed; studies were diverse in design, outcome measures and the training provided for peer patients. Peer simulation positively influences student communication and development of patient empathy and offers an alternative to learning with SPs. Further rigorous research is required to understand the impact of peer simulation for a broader range of learning outcomes and to confirm the impact of this developing educational approach.

Understanding the impact of age, gender, height and body mass index on children's balance.

AIM: This research aimed to understand the influence of age, gender, height and body mass index (BMI) on balance ability in children aged 4-12 years. The secondary aim was to develop normative values for three balance tests on the Balance Master system. METHODS: Children were recruited in 2017 through community advertising. Balance testing occurred at three recreational centres in Frankston, Victoria, Australia. Data were collected by the Rhythmic Weight Shift, modified Clinical Test of Sensory Integration and Limits of Stability balance tests of the Balance Master equipment. Multiple regression analysis determined associations between variables including age, gender, height and BMI. RESULTS: There were 91 children recruited and consented. Children were aged between 4 and 12 years old. Balance ability was shown to improve with age (P < .05), with girls demonstrating more mature balance strategies at earlier ages. Decreased BMI was associated with greater balance ability and postural control (P < .05). CONCLUSION: The normative values established may be used to support clinical paediatric assessment with this equipment. Findings of this study suggest that increased BMI may be associated with poorer balance ability in children. However, further research studies are needed to explore this assertion.
