Use of Unmanned Aerial Vehicles in Wilderness Search and Rescue Operations: A Scoping Review.

Wilderness Search and Rescue (WSAR) focuses on locating and extricating missing persons in remote settings. As unmanned aerial vehicle (UAV) or "drone" technology has evolved, so has the literature describing its application in WSAR operations. We conducted a scoping review of literature that describes the use of UAVs in WSAR contexts. The Joanna Briggs Institute Framework for scoping reviews was followed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews method. Additional individual databases, article reference lists, and relevant grey literature were also included in the search to provide an impartial scope. Seven hundred forty-seven articles were identified. Of these, 56 were found to be duplicates. The remaining 691 were further screened and checked for eligibility. Ultimately, 21 studies were found that met our inclusion criteria. This literature supports the use of UAVs to increase the safety and efficiency of a WSAR operation for locating victims, assessing risks, carrying equipment, and restoring communication systems. Unmanned aerial vehicles are a potentially useful adjunct in the management of WSAR operations. Their limitations include objects obscuring victims, weather changes, uneven terrain, battery-limited flight time, and susceptibility to environmental damage.

Prevalence of hypertension in a sample of community members in a low-income peri-urban setting in Gaborone, Botswana.

Background: Cardiovascular disease remains the leading cause of death worldwide. Hypertension is a primary risk factor for the development of cardiovascular disease and affects more than a quarter of the global adult population. Africa is a continent where the prevalence of non-communicable diseases including cardiovascular disease and hypertension, is increasing rapidly. Botswana is a developing country in Sub-Saharan Africa. In such contexts the early identification of hypertension, through community screening initiatives, is an important tool for the management of cardiovascular disease in the population. Objective: To investigate and describe the prevalence of hypertension in a sample of community members residing in a low-income peri-urban setting in Gaborone, Botswana. Method: 364 adult participants had their blood pressures measured during a community health screening exercise. The values were analysed and categorised using the American Heart Association classification scale as either being normal, elevated, hypertensive stage 1 or hypertensive stage 2. Results: 234/364 (64%) of participants were found to have blood pressures within normal limits. 53/364 (15%) had elevated blood pressures, 57/364 (16%) were in hypertensive stage 1 and 20/364 (5%) were in hypertensive stage 2. Conclusions: Hypertension in Africa is a growing concern. Botswana appears to be no exception with a 36% prevalence of abnormal blood pressures being recorded. However, the majority of these were classified as elevated or stage 1. Early identification and treatment of hypertension in these early stages can significantly decrease the risk of developing stage 2 hypertension and the related systemic complications.

Workplace violence against paramedic personnel: a protocol for a scoping review.

INTRODUCTION: There is evidence to suggest that violence against paramedic personnel is increasing. Several authors report adverse effects linked to exposure to workplace violence. There remain gaps in the knowledge related to specific aspects of workplace violence experienced by paramedics in the prehospital setting. METHODS AND ANALYSIS: This scoping review will consider evidence relating to workplace violence against paramedic personnel. All types of evidence will be considered, including quantitative and qualitative studies, systematic reviews, opinion papers, grey literature, text and papers as well as unpublished materials. This scoping review will be designed and conducted in accordance with the JBI methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews will guide the reporting process. Sources will include ERIC, Scopus, PubMed, CINAHL, Cochrane Library, ScienceDirect, Web of Science, Sabinet and the DOAJ as well as OpenGrey (https://opengrey.eu/). All sources published in English will be considered for inclusion and no date limit will be applied. The searching of the databases will begin 16 January 2023 and will be concluded by 30 January 2023. Three independent reviewers will conduct the study selection and data extraction process. In the event of disagreement related to a particular source, this will be resolved by discussion. The findings of the proposed review will be presented in a narrative style that uses diagrams and tables for reporting. ETHICS AND DISSEMINATION: This scoping review will use published literature available in the public domain and will involve no participants, meaning that ethical approval is not required. The findings of the proposed review will be published in topic relevant peer-reviewed journals and will be presented at associated conferences.

Doctors', nurses' and clinical associates' understanding of emergency care practitioners.

BACKGROUND: Healthcare professionals' understanding of the knowledge, skills and training of their counterparts from other disciplines cultivates appreciation and respect within the workplace. This, in turn, results in better teamwork and improved patient care. Emergency departments are places where emergency care practitioners (ECPs) engage with doctors, nurses and clinical associates. Whilst the importance of inter-professional communication and teamwork between in-hospital professionals and pre-hospital emergency care providers is acknowledged, no literature could be found describing exactly how much these in-hospital professionals understand about the training and capabilities of their ECP colleagues. AIM: The aim of this study was to assess the level of understanding that prospective doctors, nurses and clinical associates have regarding the training and capabilities of ECPs. SETTING: The research was conducted in Johannesburg, South Africa, at two universities. METHODS: Seventy-seven participants completed a purpose-designed questionnaire assessing their understanding regarding the education and clinical capabilities of ECPs. RESULTS: In total, 64% of participants demonstrated a poor understanding of the level of education and clinical capabilities of ECPs. The remaining 36% showed only moderate levels of understanding. CONCLUSION: Medical, nursing and clinical associate graduates have a generally poor understanding of the education and clinical capabilities of their ECP colleagues who practise predominantly in the pre-hospital environment. This lack of understanding can become a barrier to effective communication between ECPs and in-hospital staff during patient handover in emergency departments. CONTRIBUTION: This research highlights a lack of understanding about the role and function of South African ECPs as pre-hospital emergency care providers and the need for more effective inter-professional education.

Barriers and facilitators to implementing coronary care networks in South Africa: a qualitative study.

BACKGROUND: ST-elevation myocardial infarction (STEMI) is on the rise in sub-Saharan Africa. South Africa consistently fails to deliver timely reperfusion to these patients, possibly due to under-developed coronary care networks (CCN). OBJECTIVES: To determine the current perceived state of CCNs, to determine the barriers to optimising CCNs and to suggest facilitators to optimising CCNs within the South African context. METHODS: A qualitative descriptive approach was employed, by performing two structured in-depth and two focus group interviews (n=4 and 5, respectively), inviting a purposely heterogeneous sample of 11 paramedics (n=4), doctors (n=5), and nurses (n=2) working within different settings in South African CCNs. Recorded interviews were transcribed verbatim and subjected to content analysis. RESULTS: Participants described an under-resourced, unprioritised and fragmented CCN with significant variation in performance. Barriers to CCN optimisation resided in recognition and diagnosis of STEMI, transport and treatment decisions, and delays. Participants suggested that thrombolysing all STEMI patients could facilitate earlier reperfusion and that pre-hospital thrombolysis should be considered. Participants highlighted the need for regionalised STEMI guidelines, and the need for further research. CONCLUSION: Numerous barriers were highlighted. Healthcare policy-makers should prioritise the development of CCNs that is underpinned by evidence and that is contextualised to each specific region within the South African health care system.

The cost-effectiveness of upfront point-of-care testing in the emergency department: a secondary analysis of a randomised, controlled trial.

BACKGROUND: Time-saving is constantly sought after in the Emergency Department (ED), and Point-of-Care (POC) testing has been shown to be an effective time-saving intervention. However, when direct costs are compared, these tests commonly appear to be cost-prohibitive. Economic viability may become apparent when the time-saving is translated into financial benefits from staffing, time- and cost-saving. The purpose of this study was to evaluate the cost-effectiveness of diagnostic investigations utilised prior to medical contact for ED patients with common medical complaints. METHODS: This was a secondary analysis of data from a prospective, randomised, controlled trial in order to assess the cost-effectiveness of upfront, POC testing. Eleven combinations of POC equivalents of commonly-used special investigations (blood tests (i-STAT and complete blood count (CBC)), electrocardiograms (ECGs) and x-rays (LODOX® (Low Dose X-ray)) were evaluated compared to the standard ED pathway with traditional diagnostic tests. The economic viability of each permutation was assessed using the Incremental Cost Effectiveness Ratio and Cost-Effectiveness Acceptability Curves. Expenses related to the POC test implementation were compared to the control group while taking staffing costs and time-saving into account. RESULTS: There were 897 medical patients randomised to receive various combinations of POC tests. The most cost-effective combination was the i-STAT+CBC permutation which, based on the time saving, would ultimately save money if implemented. All LODOX®-containing permutations were costlier but still saved time. Non-LODOX® permutations were virtually 100% cost-effective if an additional cost of US$50 per patient was considered acceptable. Higher staffing costs would make using POC testing even more economical. CONCLUSIONS: In certain combinations, upfront, POC testing is more cost-effective than standard diagnostic testing for common ED undifferentiated medical presentations - the most economical POC test combination being the i-STAT + CBC. Upfront POC testing in the ED has the potential to not only save time but also to save money. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03102216.

A prehospital randomised controlled trial in South Africa: Challenges and lessons learnt.

The incidence of cardiovascular disease and STEMI is on the rise in sub-Saharan Africa. Timely treatment is essential to reduce mortality. Internationally, prehospital 12 lead ECG telemetry has been proposed to reduce time to reperfusion. Its value in South Africa has not been established. The aim of this study was to determine the effect of prehospital 12 lead ECG telemetry on the PCI-times of STEMI patients in South Africa. A multicentre randomised controlled trial was attempted among adult patients with prehospital 12 lead ECG evidence of STEMI. Due to poor enrolment and small sample sizes, meaningful analyses could not be made. The challenges and lessons learnt from this attempt at Africa's first prehospital RCT are discussed. Challenges associated with conducting this RCT related to the healthcare landscape, resources, training of paramedics, rollout and randomisation, technology, consent and research culture. High quality evidence to guide prehospital emergency care practice is lacking both in Africa and the rest of the world. This is likely due to the difficulties with performing prehospital clinical trials. Every trial will be unique to the test intervention and setting of each study, but by considering some of the challenges and lessons learnt in the attempt at this trial, future studies might experience less difficulty. This may lead to a stronger evidence-base for prehospital emergency care.

The cost of time: A randomised, controlled trial to assess the economic impact of upfront, point-of-care blood tests in the Emergency Centre.

INTRODUCTION: Time and cost constraints abound in the Emergency Centre (EC). These resource-constraints are further magnified in low- and middle-income countries (LMIC). Almost half of all patients presenting to the EC require laboratory tests. Unfortunately, access to laboratory services in LMIC is commonly inadequate. Point-of-Care (POC) tests may assist to avert this shortcoming. The aims of this study were to evaluate the cost effectiveness of upfront POC blood tests performed prior to doctor assessment compared to the standard EC workflow. METHODS: A secondary analysis was performed on data from a prospective, randomised, controlled trial where patients with abdominal/chest symptoms or generalised body pain/weakness followed either the normal EC workflow pathway or one of two enhanced workflow pathways with POC tests (i-STAT with and without a complete blood count (CBC)) prior to doctor evaluation. The incremental cost effectiveness ratio (ICER) was used to perform the cost effectiveness analysis. RESULTS: There were 248 patients enrolled in the study. The use of the two upfront, POC test pathways significantly exceeded the primary outcome measure of a 20% reduction in treatment time. In the i-STAT + CBC group, the 31 min. time-saving translated into cost-saving of US$14.96 per patient (IECR 0.27) whereas the 21 min. time-saving in the i-STAT only group only had an additional net cost of US$3.11 per patient (IECR 0.90). CONCLUSION: Upfront, POC blood tests can be utilised in the resource-constrained EC to manage patients more efficiently by saving time. This time-saving can, in fact, be more cost effective than traditional EC workflow making it an economically viable option for implementation in LMIC.

Doctors' perceptions of the impact of upfront point-of-care testing in the emergency department.

OBJECTIVES: Special investigations (e.g. blood tests, electrocardiograms, x-rays) play an integral role in patient management in the emergency department (ED). Having results immediately available prior to assessing a patient may lead to improved efficiency. This could be instituted by utilizing point-of-care (POC) testing with an alternative ED workflow, but the implementation would be dependent on acceptance by the end-users. The aim of this study was to assess doctors' perceptions of POC testing in the ED when the normal treatment pathway was modified to use upfront POC tests performed prior to doctor evaluation in an effort to decrease treatment times. METHODS: A prospective, randomized, controlled trial was performed in the ED where medical patients received either the normal ED workflow pathway or one of the enhanced workflow pathways with POC tests in various combinations prior to doctor evaluation. At the end of the study period, doctors were invited to participate in an anonymous survey to gauge their opinions on the implementation of the early POC testing. RESULTS: Overall, the doctors surveyed were very satisfied with use of upfront POC in the ED. One hundred per cent of the 28 doctors surveyed found it helpful to assess patients who already had test results available and would want it to be permanently available. Normalized satisfaction scores were more favorable for combinations of 3 or more tests (0.7-1.0) as opposed to combinations with 2 or less tests (0.3-0.7). There was a preference for combinations that included comprehensive blood results. CONCLUSION: The implementation of workflow changes to assist doctors in the ED can potentially make them more productive. End-user buy-in is essential in order for the change to be successful. Upfront, protocolised, POC testing is a low-input, high-yield intervention that decreased treatment time and satisfied doctors.

Views of emergency care providers about factors that extend on-scene time intervals.

INTRODUCTION: Rapid response, patient care and transportation remain recognised goals of the Emergency Medical Services (EMS). Spending more time on-scene may delay the initiation of definitive care interventions. This study focused on describing the perceptions of a sample of emergency care providers regarding the impact of environmental, clinical and systemic factors with respect to their on-scene time intervals. METHOD: The study was descriptive and prospective in nature making use of a self-designed questionnaire. Basic descriptive methods were used during the analysis of the participants' responses to 16 close-ended questions. A further review of the limited narrative elicited by two open-ended questions allowed for the reporting of additional views and opinions. RESULTS: Thirty-three (92%) participants agreed that extended time on-scene may negatively affect patient outcome. Twenty-three (64%) agreed that spending longer than 20 min on-scene may be considered excessive for medical emergencies and 28 (77%) felt the same for trauma cases. Respondents felt that many of the environmental, clinical and systemic factors mentioned in the questionnaire do have the potential to extend on-scene time intervals. The factors that were seen to have the greatest effect included waiting for fire, rescue and police services, patient acuity, the use of an air ambulance, patient extrication and multi-casualty incidents. DISCUSSION: There are a number of environmental, clinical and systemic factors that emergency care providers indicate have the potential to extend on-scene time intervals. Acknowledging and attempting to address these factors is important for EMS as limiting the time spent on-scene is not only clinically desirable but may also lead to improved efficiency and availability of resources.

Paediatric weight estimation practices of advanced life support providers in Johannesburg, South Africa.

INTRODUCTION: The choice of weight estimation method to use during prehospital paediatric emergency care is important because it needs to be both accurate and easy to use. Accuracy is important to ensure optimum drug dosing while ease-of-use is important to minimise user errors and the cognitive load experienced by healthcare providers. Little is known about which weight estimation systems are used in the prehospital environment anywhere in the world. This knowledge is important because if the use of inappropriate weight estimation practices is identified, it could be remedied through education and institutional policies. METHODS: This was a prospective questionnaire study conducted in Johannesburg, South Africa, which obtained information on the knowledge, attitude and practice of weight estimation amongst advanced life support (ALS) paramedics. RESULTS: Forty participants were enrolled, from both the public and private sectors. The participants' preferred method of weight estimation was visual estimation (7/40; 18%), age-based formulas (16/40; 40%), parental estimation (3/40; 8%), the Broselow tape (2/40; 5%) and the PAWPER tape (11/40; 28%). No participant was familiar with or used the Mercy method. All participants were very confident in the accuracy of their selected system. DISCUSSION: The knowledge and understanding of weight estimation systems by many advanced life support paramedics was poor and the use of inappropriate weight estimation systems was common. Further education and intervention is needed in order to change the sub-optimal weight estimation practices of ALS paramedics in Johannesburg.

A Randomized Controlled Trial to Assess the Impact of Upfront Point-of-Care Testing on Emergency Department Treatment Time.

OBJECTIVES: To compare standard emergency department (ED) workflow to a protocolized pathway using upfront point-of-care (POC) tests performed prior to doctor evaluation to determine if this could produce a significant reduction in treatment time. METHODS: We performed a prospective, randomized, controlled trial. Patients were randomized to receive the standard of care or one of the enhanced workflow pathways with POC tests. RESULTS: There were 1,044 patients enrolled. All workflows, except electrocardiogram and low-dose x-ray (LODOX), exceeded the outcome measure (20% reduction in treatment time). It was significantly shorter compared with the control workflow if the patient received any (i-STAT + CBC)-containing workflows (P = .0001, P = .020, P = .0009, P = .011), as well as the i-STAT + LODOX workflows (P = .0001, P = .034). CONCLUSIONS: The full benefit of POC testing can be realized if it is implemented prior to doctor evaluation, as part of a standardized procedure in the ED. This allows for a more rapid availability of investigation results subsequently leading to decreased treatment times.

The proportion of South Africans living within 60 and 120 minutes of a percutaneous coronary intervention facility.

INTRODUCTION: Timely reperfusion, preferably via percutaneous coronary intervention (PCI) following myocardial infarction, improves mortality rates. Emergency medical services play a pivotal role in recognising and transporting patients with ST-elevation myocardial infarction directly to a PCI facility to avoid delays to reperfusion. Access to PCI is, in part, dependant on the geographic distribution of patients around PCI facilities. The aim of this study was to determine the proportion of South Africans living within 60 and 120 minutes of a PCI facility. METHODS: PCI facility and population data were subjected to proximity analysis to determine the average drive times from municipal ward centroids to PCI facilities for each province in South Africa. Thereafter, the population of each ward living within 60 and 120 minutes of a PCI facility was extrapolated. RESULTS: Approximately 53.8 and 71.53% of the South African population live within 60 and 120 minutes of a PCI facility. The median (IQR, range) drive times and distances to a PCI facility are 100 minutes (120.4 min, 0.7-751.8) across 123.6 km (157.6 km, 0.3-940.8). CONCLUSION: Based on the proximity of South Africans to PCI facilities, it seems possible that most patients could receive timely PCI within 120 minutes of first medical contact. However, this may be unlikely for some due to a lack of medical insurance, under-developed referral networks or other system delays. Coronary care networks should be developed based on the proximity of communities to 12-lead ECG and reperfusion therapies (such as PCI facilities). Public and private healthcare partnerships should be fortified to allow for patients without medical insurance to have equal accesses to PCI facilities.

Hypothermia in trauma patients arriving at an emergency department by ambulance in Johannesburg, South Africa: a prospective study.

INTRODUCTION: Normal body temperature is considered to be between 36 and 38°C. Temperatures that are too low may negatively affect physiological functions. In trauma cases, factors that promote the development of hypothermia include concomitant hypoxia, hypotension, decreased levels of consciousness, contact with cold surfaces, exposure to low ambient temperatures and the administration of cold fluids. Studies on emergency department related hypothermia in Africa are sparse. This study investigated instances of hypothermia in a sample of trauma cases arriving by ambulance to an emergency department in Johannesburg, South Africa. METHODS: Core body temperatures of 140 trauma cases were measured upon arrival and 30 minutes later. Ambient temperatures outside the hospital, inside the ED and in the resuscitation areas were also recorded. Additional information was gathered describing the equipment available to the ambulance crews for temperature, control and rewarming. RESULTS: Seventy-two (51%) of the cases were found to have core body temperatures less than 36°C upon arrival. Twenty-nine (21%) the cases were considered clinically hypothermic (core temperatures of less than <35°C). After 30 minutes, 79 (56%) of the participants had core body temperatures of less than 36°C and 39 (28%) remained lower than 35°C. Patients were not warming up in the ED as expected. Rather, some had become colder. The study also found that the ambient temperature in the triage area fluctuated and was recorded as less than the recommended 21°C in 95 (68%) of the cases. In addition, the majority of ambulances that transported these cases lacked appropriate equipment on board to properly facilitate temperature control and rewarming. CONCLUSION: Fifty-one percent of the trauma cases arriving by ambulance had core temperature <36°C. Many became even colder in the ED. Attention needs to be given to the early identification of hypothermia, the regulation of ambient temperatures inside the ED including the provision of appropriate heating and rewarming devices on ambulances.

Challenges relating to the inter-facility transport of high acuity paediatric cases.

INTRODUCTION: The motivation for this study came from anecdotal reports and observations that there was a potential need for improvement to the systems that support inter-facility transfers of high acuity paediatric cases between referring and receiving facilities in Johannesburg, South Africa. In this exploratory study, we formally document and describe challenges being experienced by members of the healthcare team in facilitating the inter-facility transport of high acuity paediatric cases. METHODS: A qualitative, explorative design was applied, making use of interviews with purposefully-identified role players involved in paediatric transportation and care. Verbatim transcripts from audio recorded interviews underwent content analysis to allow for the identification of common categories. RESULTS: Participants described a number of challenges, which included time delays, lack of qualified ambulance personnel, poor communication between role players, and lack of appropriate equipment. DISCUSSION: There are significant challenges experienced by members of the healthcare team with regard to inter-facility transport of high acuity paediatric and neonatal cases in Johannesburg, South Africa. Whilst we acknowledge the African context and resource constrained setting, health systems managers need to explore the feasibility of establishing dedicated and suitably resourced retrieval teams who specialise in the transfer of high acuity paediatric and neonatal patients in order to improve quality of care and overall patient outcomes in this population.

Use of morphine sulphate by South African paramedics for prehospital pain management.

BACKGROUND: Evidence in the literature highlights the fact that acute pain in the prehospital setting remains poorly managed. Morphine remains the most commonly used analgesic agent in the South African prehospital emergency care setting. Although guidelines and protocols relating to the dosage and administration of morphine exist, little data are available describing its use by South African paramedics. OBJECTIVES: To document and describe the way in which morphine is administered by a sample of South African paramedics for the management of acute pain in the prehospital setting. METHODS: An Internet-based survey was conducted. Sixty South African paramedics responded by completing the online questionnaire documenting and describing their use of morphine for management of acute pain. RESULTS: Results revealed that participants appeared to be overly cautious of potential adverse effects associated with administration of morphine. Although the majority of participants calculated the dose of morphine to be administered correctly according to the patient's weight, the majority do not appear to be administering this as a bolus; rather, they administer the calculated loading dose in a titrated manner over time. This method may result in a delay and or failure to adequately achieve therapeutic serum levels. CONCLUSION: Failure to administer an appropriate bolus or 'loading dose' when administering morphine intravenously may result in ineffective and delayed pain management. The authors recommend more clearly defined protocols be developed to guide the use of morphine sulphate by paramedics in the local emergency medical services environment.

Factors affecting the frequency of vascular access via intraosseous cannulation performed by paramedics in Johannesburg.

PURPOSE: In an emergency, the administration of fluids and medications remains a vital component of patient care. Although this is usually achieved via an intravenous line, intraosseous (IO) cannulation is accepted as a useful alternative for the administration of fluids and medications in situations where intravenous cannulation is difficult or impossible. Despite this, IO cannulation appeared to be infrequently performed by paramedics in Johannesburg (JHB). This study investigated factors that may be affecting the frequency with which IO cannulation is performed by paramedics in JHB. METHODS: A qualitative design was utilized making use of one-on-one interviews with 12 purposefully selected operational paramedics from emergency medical services in JHB. The interviews were recorded and transcribed. Introspective analysis and interpretive phenomenological analysis were conducted to identify emerging themes and patterns. RESULTS: IO cannulation is infrequently performed by paramedics in JHB. Factors identified that reduce the likelihood of the procedure being performed included "Negative Perceptions Relating to the Procedure"; "Practitioner Success at Intravenous Cannulation"; "Close Proximity of Hospitals"; "Patient Profile, Presentation and Case Load"; "Lack of Appropriate Equipment"; and "Lack of Appropriate Training." CONCLUSION: Procedures are more inclined to move from the in-hospital to the prehospital environment if they are seen to be commonly performed, safe and effective. It would appear that paramedics infrequently witness IO cannulation being performed in emergency departments. This together with a lack of appropriate equipment, training and retraining including the perceived invasiveness and pain associated with the procedure appears to be dissuading paramedics from regularly performing IO cannulation.
