An Assessment of Psychological Need in Emergency Medical Staff in the Northern Health and Social Care Trust Area

Setting: Psychological stress is increasingly recognised within emergency medicine, given the environmental and clinical stressors associated with the specialism. The current study assessed whether psychological distress is experienced by emergency medical staff and if so, what is the expressed need within this population? Participants: Participants included ambulance personnel, nursing staff, doctors and ancillary support staff within two Accident and Emergency (A&E) departments and twelve ambulance bases within one Trust locality in NI (N = 107). Primary and secondary outcome measures: The General Health Questionnaire (GHQ-12, Goldberg, 1972, 1978), Secondary Traumatic Stress Scale (STSS, Bride, 2004) and an assessment of need questionnaire were completed and explored using mixed method analysis. Results: Results showed elevated levels of psychological distress within each profession except ambulance service clinical support officers (CSOs). Elevated levels of secondary trauma symptomatology were also found; the highest were within some nursing grades and junior doctors. Decreased enjoyment in job over time was significantly associated with higher scores. Analysis of qualitative data identified sources of stress to include low morale. A total of 65% of participants thought that work related stressors had negatively affected their mental health. Participants explored what they felt could decrease psychological distress including improved resources and psychoeducation. Conclusion: There were elevated levels of distress and secondary traumatic stress within this population as well as an expressed level of need, on both systemic and support levels.

Optimization models and methods for real-time transportation planning in forestry

Lors du transport du bois de la forêt vers les usines, de nombreux événements imprévus peuvent se produire, événements qui perturbent les trajets prévus (par exemple, en raison des conditions météo, des feux de forêt, de la présence de nouveaux chargements, etc.). Lorsque de tels événements ne sont connus que durant un trajet, le camion qui accomplit ce trajet doit être détourné vers un chemin alternatif. En l’absence d’informations sur un tel chemin, le chauffeur du camion est susceptible de choisir un chemin alternatif inutilement long ou pire, qui est lui-même "fermé" suite à un événement imprévu. Il est donc essentiel de fournir aux chauffeurs des informations en temps réel, en particulier des suggestions de chemins alternatifs lorsqu’une route prévue s’avère impraticable. Les possibilités de recours en cas d’imprévus dépendent des caractéristiques de la chaîne logistique étudiée comme la présence de camions auto-chargeurs et la politique de gestion du transport. Nous présentons trois articles traitant de contextes d’application différents ainsi que des modèles et des méthodes de résolution adaptés à chacun des contextes. Dans le premier article, les chauffeurs de camion disposent de l’ensemble du plan hebdomadaire de la semaine en cours. Dans ce contexte, tous les efforts doivent être faits pour minimiser les changements apportés au plan initial. Bien que la flotte de camions soit homogène, il y a un ordre de priorité des chauffeurs. Les plus prioritaires obtiennent les volumes de travail les plus importants. Minimiser les changements dans leurs plans est également une priorité. Étant donné que les conséquences des événements imprévus sur le plan de transport sont essentiellement des annulations et/ou des retards de certains voyages, l’approche proposée traite d’abord l’annulation et le retard d’un seul voyage, puis elle est généralisée pour traiter des événements plus complexes. Dans cette ap- proche, nous essayons de re-planifier les voyages impactés durant la même semaine de telle sorte qu’une chargeuse soit libre au moment de l’arrivée du camion à la fois au site forestier et à l’usine. De cette façon, les voyages des autres camions ne seront pas mo- difiés. Cette approche fournit aux répartiteurs des plans alternatifs en quelques secondes. De meilleures solutions pourraient être obtenues si le répartiteur était autorisé à apporter plus de modifications au plan initial. Dans le second article, nous considérons un contexte où un seul voyage à la fois est communiqué aux chauffeurs. Le répartiteur attend jusqu’à ce que le chauffeur termine son voyage avant de lui révéler le prochain voyage. Ce contexte est plus souple et offre plus de possibilités de recours en cas d’imprévus. En plus, le problème hebdomadaire peut être divisé en des problèmes quotidiens, puisque la demande est quotidienne et les usines sont ouvertes pendant des périodes limitées durant la journée. Nous utilisons un modèle de programmation mathématique basé sur un réseau espace-temps pour réagir aux perturbations. Bien que ces dernières puissent avoir des effets différents sur le plan de transport initial, une caractéristique clé du modèle proposé est qu’il reste valable pour traiter tous les imprévus, quelle que soit leur nature. En effet, l’impact de ces événements est capturé dans le réseau espace-temps et dans les paramètres d’entrée plutôt que dans le modèle lui-même. Le modèle est résolu pour la journée en cours chaque fois qu’un événement imprévu est révélé. Dans le dernier article, la flotte de camions est hétérogène, comprenant des camions avec des chargeuses à bord. La configuration des routes de ces camions est différente de celle des camions réguliers, car ils ne doivent pas être synchronisés avec les chargeuses. Nous utilisons un modèle mathématique où les colonnes peuvent être facilement et naturellement interprétées comme des itinéraires de camions. Nous résolvons ce modèle en utilisant la génération de colonnes. Dans un premier temps, nous relaxons l’intégralité des variables de décision et nous considérons seulement un sous-ensemble des itinéraires réalisables. Les itinéraires avec un potentiel d’amélioration de la solution courante sont ajoutés au modèle de manière itérative. Un réseau espace-temps est utilisé à la fois pour représenter les impacts des événements imprévus et pour générer ces itinéraires. La solution obtenue est généralement fractionnaire et un algorithme de branch-and-price est utilisé pour trouver des solutions entières. Plusieurs scénarios de perturbation ont été développés pour tester l’approche proposée sur des études de cas provenant de l’industrie forestière canadienne et les résultats numériques sont présentés pour les trois contextes.

Stress e Emergência Médica: níveis e factores de stress em profissionais de emergência pré–hospitalar

O stress é a doença da actualidade, devido à exigência e à pressão emocional que o meio pode exercer sobre todas as pessoas, quer no seu ambiente pessoal quer no ambiente profissional. O termo stress serve cada vez mais como justificação ou forma de expressão de irritações, mal-estar físico e mental, cansaço, ansiedade e depressões. Todavia torna-se pertinente percebermos a evolução do stress enquanto conceito e enquanto doença. Neste trabalho contextualizamos o stress no âmbito da Emergência Pré – Hospitalar, explorando-o, avaliando-o e analisando-o, de modo a podermos perceber os níveis de stress e de que forma os Profissionais de Emergência a ele estão sujeitos. Considerando a base teórica deste estudo definimos, como objectivo geral do trabalho, a avaliação de níveis e factores de stress percepcionados pelos profissionais de emergência médica e como objectivos específicos do estudo a descrever e caracterizar, a nível da região centro, os indivíduos que desempenham funções na emergência préhospitalar, verificar a percepção dos mesmos no que respeita ao stress na sua vida profissional, conhecer como percepcionam os níveis de stress em situações profissionais de emergência e identificar a sua percepção no que concerne aos níveis de stress diário no seu quotidiano. Com estes objectivos, utilizamos uma amostra de 184 profissionais de Emergência Médica divididos por quatro profissões [Médicos, Enfermeiros, Técnicos de Ambulância de Emergência (TAE) e Operadores de Central de Emergência Médica(OPCEM)], com idades compreendidas entre os 20 e os 56 anos. Realizámos ainda um estudo descritivo explorando os questionários de stress no INEM (Instituto Nacional de Emergência Médica) e o Questionário de Vulnerabilidade do Stress com variáveis do estudo demográfico. Podemos concluir que o stress está presente nas actividades de emergência. A sua presença relaciona-se, por um lado, com uma maior ou menor discriminação dos factores stressantes e, por outro, numa maior ou menor centração no sujeito, nomeadamente, um maior perfeccionismo e intolerância à frustração que se apresentam como distressantes para a actividade profissional de emergência. Os aspectos estudados permitem-nos clarificar o sentido e a utilidade do conceito, a sua operacionalidade e a sua importância nos profissionais de emergência. / Stress is the disease of our time, due to the requirement and emotional pressure that the media can have on all people, both in their personal environment and in the professional environment. The word stress increasingly serves as a justification or form of expression of irritation, physical discomfort and mental fatigue, anxiety and depression. However it is pertinent to realize the evolution of stress as a concept and as a disease. In this work, we contextualize under the stress of the Pre - Hospital Emergency, exploring it, assessing it and analyzing it, so you can see the stress levels and how the Emergency Professionals are subject to it. Whereas the theoretical basis of this study as a strategic objective of the work, the assessment of levels and stress factors perceived by medical emergency professionals and specific objectives of the study description and characterization, the level of the center, individuals who perform functions in pre-hospital emergency, check their perception with regard to the stress in your life, know how they experience the stress levels of professionals in emergency situations and identify the perceptions of individuals regarding the levels of daily stress in their daily lives. For this we used a sample of 184 professionals of Medical Emergency divided by four professions [(Doctors, Nurses, Technicians Ambulance Emergency (TAE), Operators of Emergency Medical Center (OPCEM)], aged 20 to 56 years. We conducted a descriptive study also exploring the questionnaires of stress in INEM(National Institute of Medical Emergency) and Vulnerability Questionnaire Stress with variables of the study population. We can conclude that stress is present in emergency activities. Its presence is related to, first, with more or less stressful factors of discrimination and, secondly, a greater or lesser concentration on the subject, in particular, greater perfectionism and intolerance to frustration that stand as unstressed for the activity of emergency professionals. The areas studied will clarify the meaning and usefulness of the concept, its operation and its importance in day-to-day occupation of emergency.

The Hanging/hanged Patient and Relevance to Pre-hospital Care

Death and injury from hanging is a complex situation, which requires careful and appropriate assessment and management in the pre-hospital environment. It is arguably an area of limited understanding and therefore may not be assessed and managed in the most effective manner. Most hanged/hanging patients will be found in their homes, rather than in institutions. It could be argued that due to prevalence as a suicide method, the majority of pre-hospital ambulance service staff will be responded to at least one hanged or hanging patient within their careers, thus a greater understanding will benefit both clinician and patient. Patients who attempt or achieve suicide will rarely achieve fracturing the spine and severing the spinal cord, bringing into question the requirement for the traditional cervical collar and spinal immobilisation techniques. Death from asphyxiation and carotid/vagal reflex require consideration and management as does raised ICP, which is likely to occur.

“Medical bag for General Practice” Just in Case: redesigning the doctor’s bag (2012)

This research addressed practice related problems from a medico-legal perspective and aims to provide a working tool that aids GPs to comply with best practice protocols. The resulting bag was developed in collaboration with General Practitioners, clinicians and members of the Medical Defense Union. Using proven methods developed within the Healthcare & Patient Safety Lab (e.g. DOME, Ambulance) to establish an evidence-based brief, this research used task, equipment and consumables analysis to determine minimum requirements and preferred layouts for task optimisation. The research established that clinicians require three distinct functions in their workspace: laying out, organisation and information retrieval. Feedback from clinicians indicates that this working tool allows them to access information and equipment wherever they may be and suggests an improvement from current practice. The research is now into a second year where the design of the bag will be refined and tested. Lifestyle and demographic changes such as the ageing population and increased prevalence of chronic diseases require more consistent standards of primary care, and care that is well coordinated and integrated (Imison, et al., 2011). Many guidelines exist relating to general practice and the doctor’s bag (NSLMC, 2008, RACGP, 2010, RCGP, 2008 and Hiramanek, 2004), however there is no standard in the UK that regulates the shape and materials of the bag or its contents. Doctors may use any sort of vessel to transport their equipment and consumables to a patient’s location. Furthermore, treating a patient in their own home, outside an ideal clinical environment, presents its own complications. A looks-like, works-like bag prototype and information system that will be used in clinical trials, the results of which will determine the manufacturing of a new, standardised bag for clinical treatment used by members of the Medical Defence Union.

Transportation of Children in Ground Ambulances: Professionals' Knowledge and Safety Measures

Background: The transport of children in ground ambulances is a rarely studied topic worldwide. The ambulance vehicle is a unique and complex environment with particular challenges for the safe, correct and effective transportation of patients. Unlike the well developed and readily available guidelines on the safe transportation of a child in motor vehicles, there is a lack on consistent specifications for transporting children in ambulances. Nurses are called daily to transfer children to hospitals or other care centers, so safe transport practices should be a major concern. Purpose: to know which are the safety precautions and specific measures used in the transport of children in ground ambulances by nurses and firefighters and to identify what knowledge these professionals had about safe modes of children transportation in ground ambulances. Methods: In this context, an exploratory - descriptive study and quantitative analysis was conducted. A questionnaire was completed by 135 nurses and firefighters / ambulance crew based on 4 possible children transport scenarios proposed by the NHTSA (National Highway Traffic Safety Administration) and covered 5 different children´s age groups (new born children, 1 to 12 months; 1 to 3 years old; 4 to 7 years old and 8 to 12 years old). Results: The main results showed a variety of safety measures used by the professionals and a significant difference between their actual mode of transportation and the mode they consider to be the ideal considering security goals. In addition, findings showed that achieved scores related to what ambulance crews do in the considered scenarios reflect mostly satisfactory levels of transportation rather than optimum levels of safety, according to NHTSA recommendations. Variables as gender, educational qualifications, occupational group and local where professionals work seem to influence the transport options. Female professionals and nurses from pediatric units appear to do a safer transportation of children in ground ambulances than other professionals. Conclusion: Several professionals refereed unawareness of the safest transportation options for children in ambulances and did not to know the existence of specific recommendations for this type of transportation. The dispersion of the results suggests the need for investment in professional training and further regulation for this type of transportation.

Use of Poppers (Amyl Nitrite): Unpleasant Side Effects in a Brothel

Introduction: Various agents can lead to an acquired methaemoglobinaemia (MHB) with potentially fatal consequences. There is a lack of literature on the formation of methaemoglobin (MH) in the blood after the intake of poppers (amyl nitrite). Poppers are a popular aphrodisiac agent. Case description: A 56-year-old diabetic called an ambulance after using poppers in a brothel with subsequent associated acrocyanosis, confusion and headache. The paramedics reported tachycardia and blood glucose of 3.8 mmol/l. The arterial blood gas analysis in the Emergency Department (ED) revealed a MHB of 23.1%. MH levels decreased rapidly without antidotal therapy. The patient was discharged the next day free of symptoms. Discussion: This case illustrates the potential risks of taking poppers. A wide spectrum of symptoms were present in our patient. For the differential diagnosis of acquired MHB, poppers should be considered.

Development, implementation and evaluation of an interprofessional graduate program for nursing-paramedicine double-degree graduates

Over the past decade, several Australian universities have offered a double degree in nursing and paramedicine. Mainstream employment models that facilitate integrated graduate practice in both nursing and paramedicine are currently lacking. The aim of the present study was to detail the development of the Interprofessional Graduate Program (IPG), the industrial and professional issues that required solutions, outcomes from the first pilot IPG group and future directions. The IPG was an 18-month program during which participants rotated between graduate nursing experience in emergency nursing at Northern Health, Melbourne, Australia and graduate paramedic experience with Ambulance Victoria. The first IPG with 10 participants ran from January 2011 to August 2012. A survey completed by nine of the 10 participants in March 2014 showed that all nine participants nominated Ambulance Victoria as their main employer and five participants were working casual shifts in nursing. Alternative graduate programs that span two health disciplines are feasible but hampered by rigid industrial relations structures and professional ideologies. Despite a 'purpose built' graduate program that spanned two disciplines, traditional organisational structures still hamper double-degree graduates using all of skills to full capacity, and force the selection of one dominant profession.

Initial destination hospital of paediatric prehospital patients in rural Victoria.

OBJECTIVE: The objective of this present study was to describe the initial destination hospital of paediatric patients transported by Ambulance Victoria paramedics within the South Western area of Victoria to determine the proportion of patients that bypassed their closest hospital. METHODS: All Ambulance Victoria primary ambulance transports for paediatric patients aged 1 month to 14 years in the Barwon South West region between 1 April 2008 and 28 February 2011 were reviewed. Each case was examined to determine the destination hospital location relative to the case scene location, and the overall nature of each case was grouped into one of seven categories (medical respiratory, medical cardiac, medical neurological, medical other, trauma time critical, and trauma non-time critical). RESULTS: There were 1191 cases identified, with 978 (82%) being taken to the closest hospital and 213 (18%) to a more distant facility. The average distance travelled from the scene to the destination hospital was 15.2 km, and almost 90% of patients transported to the nearest hospital were within 15 km of that hospital. Time critical trauma cases and respiratory-related medical cases had higher rates of transport to more distant hospitals as their initial destination (26% to non-closest and 23% to non-closest, respectively). CONCLUSION: The patient's condition and their location relative to the larger medical facilities appear to influence the decision of destination hospital. Uncertainty regarding the availability of 24 h hospital services and staffing details may contribute to longer transfers.

Analysis of the impact of limitation of medical treatment orders during unplanned transfers from sub-acute care to emergency departments

BACKGROUND: The impact of limitation of medical treatment orders (LOMT) on patient outcomes following transfer from sub-acute care to the Emergency Department remains unclear.

METHODS: Retrospective medical record review of 431 adult in-patients who required ambulance transfer following clinical deterioration during a sub-acute care admission during 2010.

RESULTS: Common reasons for transfer were respiratory (18.9%) or neurological (19.0%) conditions; 35.7% (154/431) were transferred within one week of sub-acute care admission. LOMT orders were in place for 37.8% (n=163) patients who were older (p<0.001), with more comorbidities (p<0.005), specifically cardiac, renal and pulmonary disease than patients without LOMT. Patients with LOMT orders had more physiological abnormalities before transfer; tachypnoea (43.7% vs 28.6%), hypoxaemia (63.5% vs 48.4%) and severe hypoxaemia (27.6% vs 14.5%). There were no differences in rates of admission, cardiac arrest, Medical Emergency Team activation or ICU admission. For admitted patients, those with LOMT orders had significantly (p≤0.005) higher mortality: in-hospital (21.9% vs 11.3%); 30 days (23.9% vs 12.3%) and 60 days (28.2% vs 13.4%).

CONCLUSIONS: Patients with LOMT had higher levels of comorbidity and were more acutely ill during their sub-acute care admission. Once transferred those with a LOMT had similar rates of cardiac arrest, MET activation and unplanned ICU admission, but higher mortality.

Health extension workers' and mothers' attitudes to maternal health service utilization and acceptance in Adwa Woreda, Tigray Region, Ethiopia.

BACKGROUND: The maternal health system in Ethiopia links health posts in rural communities (kebeles) with district (woreda) health centres, and health centres with primary hospitals. At each health post two Health Extension Workers (HEWs) assist women with birth preparedness, complication readiness, and mobilize communities to facilitate timely referral to mid-level service providers. This study explored HEWs' and mother's attitudes to maternal health services in Adwa Woreda, Tigray Region. METHODS: In this qualitative study, we trained 16 HEWs to interview 45 women to gain a better understanding of the social context of maternal health related behaviours. Themes included barriers to health services; women's social status and mobility; and women's perceptions of skilled birth attendant's care. All data were analyzed thematically. FINDINGS: There have been substantial efforts to improve maternal health and reduce maternal mortality in Adwa Woreda. Women identified barriers to healthcare including distance and lack of transportation due to geographical factors; the absence of many husbands due to off-woreda farming; traditional factors such as zwar (some pregnant women are afraid of meeting other pregnant women), and discouragement from mothers and mothers-in-law who delivered their children at home. Some women experienced disrespectful care at the hospital. Facilitators to skilled birth attendance included: identification of pregnant women through Women's Development Groups (WDGs), and referral by ambulance to health facilities either before a woman's Expected Due Date (EDD) or if labour started at home. CONCLUSION: With the support of WDGs, HEWs have increased the rate of skilled birth attendance by calling ambulances to transfer women to health centres either before their EDD or when labour starts at home. These findings add to the growing body of evidence that health workers at the community level can work with women's groups to improve maternal health, thus reducing the need for emergency obstetric care in low-income countries.

Changing the place of birth from home to health facilities in Kafa Zone, Ethiopia

Women in rural and semi-urban Kafa Zone, Ethiopia are being encouraged to give birth in health facilities rather than at home. Using an earlier 2007 study as a comparison point, this study explored the role of Health Extension Workers (HEWs) in referring women to health centres for birth. Semi-structured interviews were conducted with 11 HEWs and 6 health workers in May and June 2014. The results show that women prefer birth attendants they know, including HEWs, and not to go to health centres or the hospital except for emergencies. The ambulance service linking rural communities with health facilities works better in some areas than others. To improve maternal health, HEWs need better support at the community level. Inefficiencies in the referral system should be addressed.
