<p>Inappropriate ambulance use can be defined broadly as the use of emergency medical services (EMS) transport for non-urgent medical conditions, or when the patient does not use alternate transportation available. It drains health system resources, contributes to low morale among paramedics, and can delay care for patients who may be appropriately treated in alternative settings. An increasing number of studies indicate <em>that</em> inappropriate EMS use occurs, but few studies investigate how perspectives of inappropriate use are constructed. This study explores the construct of appropriateness in the context of ambulance use, and examines the implications of varying perspectives on ambulance billing policies.</p> <p>We present a grounded theory on the construct of appropriate ambulance use from interviews with paramedics in Ontario, national media reports and online reader commentary. Findings show that the role of paramedics varies across regions, and includes various types of care (e.g., emergency response, primary care and preventative care), and transportation (e.g., to the emergency department or urgent care clinics). In turn, constructs of appropriateness vary. In ambiguous cases, paramedics use their perception of the patients’ ability or attempts to cope with the medical situation to evaluate the appropriateness of ambulance use. Unexpectedly, the most frustrating cases of inappropriate ambulance use tend to be initiated by organizations, such as long-term care facilities, rather than members of the general public. These findings raise questions about the potential for ambulance user fees conditional on ‘appropriateness’ to improve either the effectiveness or the efficiency of ambulance services.</p> / Doctor of Philosophy (PhD)

Introduktion: I den moderna prehospitala akutsjukvården kan ambulansens och ambulanshelikopterns samverkan ha stor betydelse för den svårt skadade eller sjuka patienten. Syfte: Syftet med studien var att undersöka vad sjuksköterskor inom ambulansen och sjuksköterska/läkare från helikoptern/akutbilen upplevde kunde påverka teamarbetet i den prehospitala miljön. Metod: En kvalitativ deskriptiv innehållsanalys med semistrukturerade intervjuer användes. 10 informanter från ett län i mellansverige inkluderades, fem kvinnor och fem män. Urvalet bestod i att informanterna skulle ha varit verksamma inom ambulansverksamheten i minst ett år samt ha erfarenhet av det prehospital samarbetet mellan ambulans och ambulanshelikopter. Intervjuerna spelades in, transkriberades till text och analyserades. Resultat: Studiens resultat presenterades i två teman med sju underkategorier. De två temana var: Ett dynamiskt teamarbete påverkas av tydliga roller och ett kontinuerligt förbättringsarbete och Teamarbete och kommunikation mellan kompetenserna i teamet. Konklusion: De olika rollerna vid teamarbetet har blivit tydligare med tiden och teamarbetet upplevdes ha blivit bättre med tiden. Hospitering och tid till övning beskrevs kunna optimera teamarbetet. Informanterna upplevde sig delaktiga i vården. Den prehospitala erfarenheten och bristen på den var av betydelse vid samverkan mellan enheterna. / Introduction: In the modern prehospital emergency care, ambulance and ambulance-helicopter's interactions play an important role for the severely injured or sick patients. Aim: The aim of the study is to examine what nurses in ambulance and nurse/doctor from the helicopter/emergency car experienced could affect the team work in the prehospital environment. Method: A qualitative descriptive content analysis of semi-structured interviews were used. 10 pieces of informants from a province in central Sweden were included five women and five men. The sample consisted of informants would have been active in the ambulance business for at least 1 year and have experience in the full spectrum of cooperation between ambulance and ambulance helicopter. The interviews were recorded, transcribed to text and analyzed. Results: The results of the study were presented in two themes with seven subcategories. The two themes were: A dynamic teamwork are influenced by clear roles and a continuous improvement and Team work and communication between the competencies of the team. Conclusion: The different roles in the cooperation has become clearer with time and team work was perceived to have become better with time. Site visits and time to exercise described to optimize teamwork. The informants perceived themselves involved in care. The prehospital experience and the lack of it was of importance to cooperation between units.

Prehospital management of patients who are traumatically injured within the state of Florida starts with the use of the Florida Adult Trauma Scorecard Methodology. The scorecard methodology may indicate that a patient is a Trauma Alert based on applied physiological and other judgment criteria. However, patients may be transported via Helicopter Emergency Medical Services (HEMS) without justified physiological needs. Rawls’ theory of justice posits that a fair and equal distribution of social resources is essential to public wellbeing. To evaluate this premise regarding prehospital trauma transports, archival 2015 data from the Florida Department of Health Trauma Registry was obtained. Using logistic regression, each trauma scorecard assessment criteria was individually and collectively evaluated regarding its predictive likelihood of a scene responder requesting HEMS versus ground ambulance transport. Controlling for trauma center locations, all five of the triage classifications illustrated a significant likelihood (p = 0.000) of HEMS transportation requests. Category 4 (EMS Judgment) predicted the highest likelihood of HEMS transport requests (b = 2.39, Wald X2(1) = 2026.88, OR = 10.9, p = .000, CI [9.83, 12.09]). Categories 4 (14.7%) and 6 (Local Criteria; [25.8%]) illustrated unexpectedly high percentages of emergency department discharge when Trauma Alert patients were HEMS transported. Over triage of patients to HEMS without meeting physiologic criteria provides less than an equal and fair distribution of public and private resources. State-level social change can be realized through HEMS transport criteria modifications applying more stringent application of physiologic patient condition scoring when determining the mode of prehospital scene response transport.

This study proposed that such a mismatch presently exists among South African urban EMS systems resulting in unacceptably high levels of inappropriate emergency responses. The purpose of this study therefore, was to evaluate the appropriateness of EMS responses in comparison to patient needs in a South African urban EMS system. Methods: All emergency cases dispatched over a 72 hour period at the Emergency Medical Communication Centre (EMCC) of the eThekwini Emergency Medical and Rescue Service (EMRS), a public sector urban EMS system, were prospectively enrolled in a quantitative study employing a descriptive, comparative design. Computer generated Vehicle Control Forms (VCF) containing dispatch data were matched and compared with Patient Report Forms (PRF) containing epidemiological and clinical data to describe the nature and extent of inappropriate responses based on patient need. Data were subjected to simple descriptive analysis and comparisons were analysed with correlations and chi-square. The Pearson's г and Spearman's rho were used to establish significance between more than two variables. Results : A total of 1689 cases were enrolled in the study of which 1385 met the inclusion criteria; 304 cases were excluded due to incomplete or duplicated data. The demand for EMS resources fluctuated widely throughout the day with levels peaking at midday and declining sharply after midnight. The median response time across all priorities was 56 minutes (IQR 59min) with just under half (46.4%) of all cases having a response time of more than an hour and almost one in ten (9.5%) exceeding 2½ hours. Significant variations existed between dispatch and on-scene priority settings and category descriptors most notable of which was seen in the highest priority ‘red code’ category which constituted more than 56% of all cases dispatched yet accounted for less than 2% on-scene (p <0.001). Conversely, over 80% of ‘red code’ responses actually required a lower priority response. Similarly, significant discrepancies were seen in the allocation of resources compared to the interventional needs of patients where it was shown that more than 58% of all cases required no interventions and just under 36% required only basic life support (BLS) level interventions (p <0.001). Of those patients triaged as ‘red code’ on-scene, less than 12% were initially allocated an appropriate Advanced Life Support (ALS) level of response and, of particular concern, only 7% of patients found to be dead or ‘blue code’ on-scene were initially dedicated a ‘red code’ response. Conclusion: South African urban EMS systems are presently unable to meet the needs of patients in terms of demand and matching resources to patient needs with evidently high levels of inconsistent and inappropriate responses resulting in sub-optimal use of limited resources.

Submitted in fulfillment of the requirements for the degree of Master of Technology: Emergency Medical Care, Durban University of Technology, Durban, South Africa, 2015. / Introduction: A Helicopter Emergency Medical Service (HEMS) is a specialist flying emergency service where on-board medical personnel have both the knowledge and equipment to perform complicated medical procedures. There is an absence of literature describing the types of patients treated and the clinical outcome of these patients flown by Helicopter Emergency Medical Services within South Africa. The paucity of literature on this topic poses a challenge for current aeromedical services as there is no baseline information on which to base flight criteria, staffing and policy documents. This has the potential to hamper the advancement of HEMS within South Africa. Purpose of the study: The purpose of this study was to undertake a descriptive analysis of the patients flown by the Netcare 911 HEMS over a 12 month period in both Gauteng and KwaZulu-Natal and to assess the patients’ outcomes. The objectives of the study were to analyse the clinical demographics of patients transported by the Netcare 911 HEMS operation, determine the time frames from dispatch of the helicopter to delivery of the patient to the receiving hospital and undertake a correlational analysis of crew qualifications, clinical procedures performed and their outcomes at 24 hours and 72 hours. A further objective was to make recommendations regarding the refinement of current aeromedical policies as well as the education and training requirements. Methodology: The research study was conducted utilizing a retrospective quantitative, descriptive design to undertake an analysis of patients transported by a private helicopter emergency medical service within South Africa. The records of all patients transported by the Netcare 911 HEMS operations between 01 January 2011 and 31 December 2011 were included. Results: In the 12 month study period there were a total of 547 cases. However, the final study population was made up of 537 cases as 10 cases had to be excluded due to incomplete documentation. Of the 537 cases, 82 (15.3%) were managed by the KwaZulu-Natal HEMS and 455 (84.7%) were managed by the Gauteng HEMS. Findings revealed that the majority of patients flown in both Gauteng and KwaZulu-Natal were adult males: males (n=398; 74.1%) and adults (n=437; 81.4%). Motor vehicle accidents were the most common incident type for both operations (n=193; 36%). At the 24-hour follow up, 339 (63.1%) patients were alive and stable and at the 72-hour follow up, 404 (75.3%) were alive and stable. Conclusion and recommendations The findings of this study provide valuable information that may have an impact on the current staffing and authorization criteria of South African HEMS operations.

The purpose of this study is to investigate the preparedness at the prehospital emergency care unit in north-western Skåne. Measuring preparedness is important to ensure that the ability to respond on emergency calls is satisfactory. To do this for north-western Skåne historical data from 2015 was extracted from SOS Alarm’s database. It was used to calculate preparedness using workload and coverage as measurements. The workload was calculated by taking the busy periods and comparing them to the ambulances working times. The coverage was calculated by defining neighbouring stations to cover for each station and then finding the amount of hours when there was no ambulance at either station. These calculations show that two of the six stations in north-western Skåne are in need of improvement. To increase the preparedness to a good level resources will have to be added at the liable stations. These resources would be new ambulances. There is a possibility to relocate ambulances from stations within the district but that would lead to a worsened preparedness for the stations which these ambulances belonged to in the first place.
