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.

Submitted in fulfillment of the requirements for the degree of Master of Health Sciences in Emergency Medical Care, Durban University of Technology, Durban, South Africa, 2017. / Introduction: Response times are considered to be one of the oldest and most popular indicators which are used to measure the efficiency of Emergency Medical Services (EMS), particularly to cases in which the patient’s condition is deemed to be life threatening. Purpose: To analyse emergency response times within the public sector Emergency Medical Services in KwaZulu-Natal and to compare these to the national norms. Methods: Using a mixed method approach, the study was conducted in two phases. The first phase involved collecting quantitative data for all the cases logged in the Umgungundlovu Health District Communications Centre over a period of one week (seven days). Phase Two involved the collection of qualitative data from focus group discussions which were conducted with three groups which had been identified. These groups included the communications centre staff, operational staff and supervisory staff. The aim of these focus group discussions was to identify factors that influenced response times as well as to propose strategies which would improve these response times. Content analysis was utilised to interpret the qualitative data which had been collected. Results: Quantitative data was collected from a total of 1 503 cases of which 680 were categorised as priority 1 (P1), 270 as priority 2 (P2) and 553 as inter facility transfer (IFT). The majority of the cases (895) had occurred in urban areas. A total of 406 cases were exempted as no patient was transported. The number of these cases was greater on days when the total case load was higher as compared to days with a lower total case load. The mean response time to cases in rural areas was 129 minutes and 110 minutes to cases in urban areas. All the time intervals were found to be longer for cases in rural areas as compared to those for cases in urban areas but with the exception of the EMD response interval. P1 cases had the shortest mean response times for both urban area cases (33 minutes) and rural area cases (95 minutes) as compared to the other case categories. Nevertheless, the national norm of 15 minutes in urban areas and 40 minutes in rural areas was not achieved in the majority of the cases. The mean Emergency Medical Dispatch (EMD) response interval was 41 minutes for P1 cases, 56 minutes for P2 cases and 96 minutes for IFT cases. The qualitative data revealed factors that impacted on the response times and helped to explain and account for the quantitative data results. Challenges regarding the availability of resources, including vehicles, staff and equipment, as well as the way in which such resources are managed, were highlighted. The high demand for services compared to the available resources was raised by the focus group participants with this high demand resulting in extended EMD response intervals. This was exacerbated by the overwhelming demand for IFT cases which are serviced by the same resources as emergency cases and which have a much longer mission time, thus delaying response times continuously. Exempt cases were also found to impact negatively on response times as, although operational vehicles are committed to these cases, services are not required. Inconsistencies with regards to case prioritisation and dispatch triage also emerged. External factors, including poor road infrastructure, lack of road names and house numbers, weather conditions and long distances between EMS bases, the patient or incident location and health care facilities were also identified as factors that resulted in extended response times. Strategies to improve the situation were explored. These strategies included the effective management of resources in order to ensure optimal availability, the introduction of a formal, computer aided, dispatch system, the adoption of demand pattern analysis and dynamic location/relocation models, standardised processes and procedures to guide all areas of EMS operations and the education of both the public and staff. Conclusion: South African EMS response time national norms for both rural and urban areas are unachievable under the majority of circumstances and, thus, they may be said to be unrealistic. Until these national norms, against which the efficiency of EMS in South Africa is measured, are revised, the service will be deemed to be incompetent. / M

Dissertation submitted in fulfilment of the requirements for the Degree of Master in Technology: Emergency Medical Care, Durban University of Technology, 2010. / South Africa currently has 1631 registered Advanced Life Support (ALS) paramedics to tend to the pre-hospital advanced life support needs of just under 50 million people. Compared to the globally accepted ratio of 1:10 000, the number of ALS paramedics in South Africa is grossly inadequate. The current shortage of South African ALS paramedics may be ascribed to migration. However, although literature on health worker migration in general abounds, there is a marked lack of national or international statistics and information on migration of ALS paramedics and their migration. Current measures to manage migration appear to be ineffective. The success of future strategies is dependent on an understanding of the migration of South African ALS paramedics - an understanding that presently does not exist. Purpose The purpose of this study was to describe the migration of South African undergraduate Advanced Life Support paramedics who qualified between 2001 and 2006, and to then develop a framework of retention strategies. In particular, it determined the extent and nature of their migration, identified the factors that have contributed to their decision to work outside South Africa and identified strategies to retain or encourage the return of ALS paramedics to practice exclusively in South Africa. Methods The study consisted of a two-phase mixed method descriptive survey. Paramedics with ALS undergraduate diplomas who qualified in South Africa between 2001 and 2006 made up the study population. Quantitative data (Phase One) was obtained from a web-based survey distributed to the accessible population (N=97). Thereafter, qualitative data (Phase Two) was gathered through in-depth interviews with selected information rich participants (n=10) also from within the accessible population. Through methodological triangulation, data from Phase One and Phase Two were Page vi integrated to obtain an in-depth understanding of South African ALS paramedic migration. Results Significant differences existed in the distribution of age (p=0.035), and years of experience post-graduation (p=0.007) and the ALS paramedic deemed most likely to migrate were individuals between the ages of 21 – 30. 15 (55%) of the participants working outside the country were engaged in short term contracts while all 24 (100%) of participants working inside South Africa were permanently employed. 18 (75%) of respondents working inside South Africa intended migrating, 12 (67%) of which intended to do so within 0 to 2 years. Nine major factors or reasons for migration were identified by participants. Working conditions, physical security and economic considerations were ranked as the top three major factors most likely to contribute to the decision or intended decision to migrate. This study also found five primary decisions that likely emerge during the life of a South African ALS Paramedic. The outcome of each decision is a result of facilitators weighted against barriers. Facilitators are factors that supported each of the primary decisions while barriers weakened or rejected them. Findings indicated that many barriers existed which rejected or weakened the decision of ALS paramedics to work inside South Africa, return to South Africa or remain in South Africa. On the converse, a vast number of facilitators existed which spurred continued migration. Conclusions As the decision to migrate may be conceptualised as early on as when individuals decide to become ALS paramedics, the constructs of return and retention strategies have to extend as far as revising recruitment policies. Preference or places into training programmes should be given to individuals who are less inclined to migrate, these include: military personnel; those already employed in the EMS, older mature candidates; candidates with families that have already settled in SA; and recognition of prior learning (RPL) candidates who are predominately obligated by contract to remain in South African EMSs.

Clinical practicum should provide students with the opportunity to combine cognitive, psychomotor and affective skills to develop competencies to prepare the qualifying practitioner for demands of pre-hospital emergency care in the real world. The aim of this study was to explore the multidimensional aspects of the clinical practicum experience of ALS paramedic students in the Western Cape through the lens of a qualitative research design. The study involved exploring the experience of paramedic students in the clinical practice placement. In addition, the views of paramedic graduates were also explored, to ascertain whether the placement experience adequately prepared them for practice. An analysis of the clinical practice documents utilised in the training of ALS paramedic students was conducted with particular reference to identify correlations with relevant literature. In addition, it was necessary to identify how clinical practice manifested itself, not only in what students and graduates express but also how it was coordinated and conveyed in a professional work related context, against the backdrop of the work integrated learning framework. Using a case study design, focus group interviews were conducted with final year EMC students from CPUT and CCA students from the Western Cape CEC. This was followed with one on one interview with paramedic graduates. Further to this, clinical practice documents were analysed to triangulate the data. This study revealed that the clinical practice learning objectives for paramedic students were not adequately achieved and paramedic graduates felt ill prepared for independent practice. These discrepancies were attributed to the complex issues both in theory and practice. The study provided a number of recommendations for improving the clinical training experience, such that paramedic graduates who enter the complex and challenging world of EMC are better prepared. / M

Submitted in fulfillment of the requirements for the degree of Master of Technology: Emergency Medical Care, Durban University of Technology, Durban, South Africa, 2013. / Background In the Emergency Medical Services (EMS), paramedics play a vital role in the treatment of critically ill or injured patients, as they are often the first link or point of contact for the patient in the healthcare setting. They may therefore also play a vital role in the prevention and control of the transmission of communicable diseases, provided that proper infection control measures are in place. The objectives of the study There is presently no national policy on communicable diseases and infection control that is specifically designed for use in the South African prehospital environment. Given the paucity of research in the area, qualitative multiple case studies were conducted to develop an ambulance specific disinfection protocol and to evaluate its effectiveness in the public sector EMS in the eThekwini District of KwaZulu-Natal. Methodology The study comprised of three phases. In the first phase focus group discussions were conducted to identify the factors needed to develop a disinfection protocol. The study population consisted of both operational and management staff from the EMS under study. The first four focus groups consisted of eight to ten EMS operational staff each and the fifth focus group consisted of five EMS management staff. Thereafter, the information gathered was used in conjunction with internationally accepted guidelines to develop an ambulance specific disinfection protocol (Phase Two). The third phase entailed the implementation of the protocol at seven ambulance bases in the eThekwini health district and the evaluation of the protocol with the use of an open-ended questionnaire at two weeks and four weeks after implementation. A single ambulance crew and their immediate supervisor from each base were utilized in this phase. Conclusion and recommendations An ambulance specific disinfection protocol was developed and implemented in the EMS under study. During the development, implementation and evaluation of the protocol, many themes with regard to infection control in EMS were identified. These themes were used to better understand the present situation in EMS in relation to infection control and in the formulation of recommendations to assist in the improvement of the present situation. The researcher recommended that all EMS staff require training and education with regard to infection control and prevention. The development and implementation of a protocol and policy document for infection control specifically for EMS is required. There is a need for the deployment of more ambulances and the employment of more operational EMS staff together with the appointment of Infection Control Supervisors at all ambulance bases. Without adequate infrastructure needed to meet infection control and prevention requirements, there may be a serious risk to both staff and the patients they serve. / M

A call taker is the first point of contact in the emergency service system and thus the interface between the caller and ambulance dispatch. Misunderstandings in an emergency call have implications for the survival of patients. Using an applied conversation analytic approach this study examined participants’ use of conversational repair as an interactional strategy. Data included 101 calls from a South African emergency medical services call centre. The data set was comprised of two distinct subsets, namely: the 107 and public corpora. The 107 corpus (53 calls) contained calls from a general emergency call centre. The 107 caller thus served as a mediating party on behalf of the public caller. The public corpus (48 calls) comprised calls received directly from members of the public. The data subsets afforded a unique opportunity to analyse ways in which participants to an emergency call manage asymmetries of knowledge. Differential patterns of the type and purpose of repair were tracked across both data sets and similarities and differences were explored. Both data sets showed that participants’ choice of interactional strategies was customized based on an ongoing assessment of knowledge asymmetries. However, whilst knowledge asymmetries posed some constraints an overriding interactional constraint, inherent within the institutional nature of the emergency call, was a rigid adherence to routinized protocols. The call taker’s dilemma was thus identified as the management of these constraints through the frequent use of conversational repair. Although a level of responsiveness is required to glean quality information from callers, high volumes of emergency calls would not be possible without routinized protocols. However, increased orientation to routinized protocols led to a decreased orientation to responsiveness. This research therefore showed that knowledge symmetry is not necessarily more advantageous but that successful call trajectory is reliant on the call taker’s ability to maximize the collaborative nature of the interaction and effectively negotiate through the judicious use of repair and other relevant interactional strategies. This has important implications for call taker training.

The theoretical research combined with practitioner-based fieldwork, shows the direct and deplorable effects of xenophobic policies coupled with a demonstrable failure to enforce healthcare access rights.

Triage assessment of patients on arrival at the emergency unit is an essential function in quality emergency care provision. Triage is the process of sorting and prioritising patients according to their level of acuity. This study was performed within an emergency unit that experienced serious problems with the sorting of patients on their arrival. After implementation of the Cape Triage Score, a questionnaire was distributed amongst staff utilising the new triage system. The investigation sought to answer specific questions concerning the triage nurse's roles, competencies required and strengths and weaknesses of the implemented system. The study also suggests guidelines to improve the triage system within the unit. The triage system was received well by participants. The roles of the triage nurse are multifaceted and extensive competencies are required. The strengths of the implemented triage system outweighed the weaknesses as perceived by the respondents. Guidelines for implementing triage in emergency units are provided. / Health Studies / M.A. (Health Studies)
