Emergency Medical Services (EMS) is an institution and product of public health, health care, and public safety that is chopped and scattered across multiple jurisdictional deployment methodologies throughout Arizona. To fully-asses the EMS needs of the state, those jurisdictions are considered as a whole; for it is the whole that makes a system, and a system is what truly impacts patient outcomes. Evaluating the ""whole"" is the genesis and driver of the 2016 Arizona Statewide EMS Needs Assessment (ASENA). The primary objective of ASENA is to establish a current ""snap-shot"" of EMS in the state while simultaneously identifying needs and/or areas that can be targeted for further analysis and/or improvement as part of Population Health Management and Emergency Medical Services Integration under the AZ Flex Grant funded by the U.S. Health Resources and Services Administration (HRSA). In addition, the secondary objective of ASENA is to compare and contrast this current ""snap-shot"" with data obtained in a more narrow needs assessment conducted in 2001, allowing comparison of changes in Arizona's critical access EMS system over 15 years. To accomplish this, a 105-question needs assessment survey tool was developed and distributed to EMS agencies throughout the state. The fully-vetted survey tool collected information pertaining to sixteen core functional sections. Eighty-six agencies fully-completed the needs assessment survey tool, with respondents evenly distributed across the state's four EMS coordinating regions and representative of the various service-delivery methodologies. The combined service areas of the respondents cover over 85% of the state's population. Arizona's statewide EMS system is well organized and positioned to deliver advanced levels of prehospital care for the vast majority of its citizens and visitors, with some variation between urban and rural regions. Key needs identified relate to: patient care reporting between EMS providers, emergency departments and receiving hospitals; quality assurance activities; education and skills training programs; dispatch system capabilities; mass casualty and public health preparedness; equipment and supplies; and more robust use of data and analyses to inform continuous EMS system improvement.

Background: Comparing Full-Time (FT) and Part-Time (PT) staffing models for a mobile integrated health (MIH) program established by a local Fire Department. Objective: Determine if the program is sustainable and which staffing model is more effective at obtaining sustainability. Design: Quality Improvement project with retrospective data review. Setting: Green Valley Fire District in Green Valley, Arizona. A predominant retirement community. Target: The residents of the Green Valley Fire District. Interventions: Utilizing the RE-AIM framework, a retrospective review of the data collected by the previously implemented MIH Program in Green Valley was completed. The framework was utilized to review relevant data and determine if the program has achieved the expected outcomes, and maintained a sustainable and transferable MIH program. Measurement: Decrease in emergency medical (EM) calls for service with the implementation of the MIH program. Comparing staffing models for consistency in services. Results: The results showed a decline in EM calls for service with the MIH program, and more consistency in availability and patient services with the FT staffing model. Limitations: The demographics of the community limit the generalizability and transferability of the data obtained from the project. Additional data should be collected and analyzed both retrospectively and for successive years to substantiate the benefits and continue to improve the effectiveness of the MIH program. Conclusions: The program could be used as a model for other MIH programs, with adjustments made for the respective community. The value or sustainability of any MIH program cannot be limited to revenue solely. Other perspectives of value added service and cost savings must also be considered. Significance: This study highlights the effectiveness of an MIH program in a small retirement community and shows the benefit of a FT staffing model versus a PT staffing model for consistency of patient care and daily program operations. There are also multiple aspects of value to an MIH program, some of which are difficult to conceptualize and measure based on historical models of healthcare delivery and Fire Department Services. Further review of these types of programs is needed to establish the overall benefits of MIH.

This critical realist thesis seeks to understand how student, graduate and professional identities emerge in Emergency Medical Science (EMS) students at a South African University of Technology (UoT) as well as in professional paramedics in the Emergency Medical Care Services (EMCS). It further considers the construct of graduate attributes (GAs) and its relationship to emergence of identity and influence on curriculum design. The research design is that of a case study. The theoretical framework is critical realism whose depth ontology posits three domains of reality. Causal powers and generative mechanisms exist in the Real domain which cause events or phenomena to emerge in the Actual domain that are experienced in the Empirical domain. Using retroduction one may come to explore some of the causes for the event. Using Bhaskar’s concepts of identity, the self, absence and emergence, ontology and four-planar social being, a Bhaskarian explanatory framework of identity to explore the emergence of identity has been created. In exploring graduate attributes, a critical realist question is posed: “What must the world be like for GAs to exist” to explore the possibilities of the existence of GAs. It was found that student identity emerges diachronically in three moments, while professional paramedic identity starts to emerge during the third year of study mainly through the structure, culture and agency of workplace-based learning. In answer to the critical realist question it was found that GAs emerge from the neoliberalist commodification of universities. In seeking an alternative to GAs, traits and attitudes were explored. It was found that these emerge from curriculum, interplay of departmental structure, culture and agency of and from students’ being which makes them ontologically radically different from GAs. This study concludes that student, graduate and professional identities emerge from a person’s core constellational identity diachronically within four-planar social being and the interplay of structure, culture and agency. GAs cannot be related to the emergence of identity and curriculum design because of their ontology; however, if traits and attitudes are substituted for GAs, a close relationship does exist between emergence of identity, traits and attitudes and curriculum design.

Introduction: Trauma is one of the leading causes of premature death and disability in South Africa. There is a paucity of data describing the prehospital trauma burden in sub-Saharan Africa. The aim of this study was to describe the epidemiology and common trauma emergencies managed by the Western Cape Government emergency medical service (WCG EMS) in South Africa. Methods: The WCG EMS call centre registry was retrospectively analysed for all trauma patients managed between 01 July 2017 to 30 June 2018. A descriptive analysis of the data was performed using standard procedures for all variables. To date, this was the first analysis of this dataset or any prehospital trauma burden managed in the Western Cape of South Africa. Results: The WCG EMS managed 492 303 cases during the study period. Of these cases, 168 980 (34.3%) or 25.9 per 1000 population were trauma related. However, only 91 196 met the inclusion criteria for the study. The majority of patients (66.4%) were males and between the socio-economically active ages of 21-40 years old (54.0%). Assaults were the most common cause of trauma emergencies, accounting for 50.2% of the EMS case load managed. The patient acuity was categorised as being urgent for 47.5% of the cases, and 74.9% of the prehospital trauma burden was transported to a secondary level health care facility for definitive care. Conclusion: This is the first report of the prehospital trauma burden managed in the Western Cape of South Africa. The Western Cape suffers a unique trauma burden that differs from what is described by the WHO or any other LMIC. It also provides the foundation for further research towards understanding the emergency care needs in South Africa and to support Afrocentric health care solutions to decrease this public health crisis.

Introduction: Adequate post-intubation sedation and analgesia (PISA) practices are important in the pre-hospital setting where vibration and noise of the transport vehicle may contribute to anxiety and pain in the patient. Inadequate post-intubation practices may lead to long-term detrimental effects in patients. Despite this, these practices are poorly described in the prehospital setting. This study aims to describe the current pre-hospital PISA practices in a private South African emergency medical service. Methodology: Patient report forms (PRF) of intubated patients between 1 Jan 2017 and 31 Dec 2017 from a single private ambulance service were reviewed. Data was analysed descriptively. Correlations were calculated with Spearman's Rank correlations and group differences were calculated with Independent T tests and Mann-Whitney U tests. Significant correlations were entered into a binomial regression model to determine predictive value of receiving PISA. Results: The number of PRFs included for analysis was 437. Of these, 69% of patients received some type of PISA. The estimated time from intubation to 1st PISA ranged from 9 to 12 minutes. There were statistically significantly more PISA interventions in patients who had received Rocuronium (p< 0.01). There was weak but significant correlation between the number of interventions and the mean arterial pressure, (rs = 0.17, p< 0.01) and Glasgow Coma Scale (rs = -0.15, p< 0.01) prior to intubation, along with the transport time to hospital (rs = 0.23, p< 0.01). Conclusion: The PISA practices in the South African pre-hospital setting is comparable to international pre-hospital settings. The time to 1st PISA appears to be shorter in the SA setting. There is an increased number of interventions in the patients who received Rocuronium, which may indicate practitioners being mindful of wakeful paralysis. Practitioners also take the level of consciousness and blood pressure prior to intubation into account when administering PISA. Longer transport times attribute to patients receiving more PISA interventions.

Sepsis is a complicated disorder in which an infection has reached the bloodstream and caused a cascade of events that in time will lead to death. Interventions aimed at identifying sepsis early in its progression are imperative to stopping the process. The purpose of this study is to examine the current state of the literature regarding sepsis screening tools utilized by emergency medical services. A literature review exploring the various tools in place was conducted to see their value in predicting sepsis and secondary what the initiation of a sepsis alert has on the patients’ outcome. Results found included that sepsis screening tools when in place decrease time to identification, decrease time to antibiotics, increase amount of fluid administration, and overall reduce hospital stay and mortality rate. With these findings educational training for EMS providers and the introduction of generalized protocols are of the upmost importance. Further research is needed to be done to create a consistent tool to be used by all EMS agencies that has a validated predictive value of sepsis.
