The impact of emergency medical helicopters on prehospital care

Emergency medical helicopter services have grown exponentially over the past seventeen years. These services offer rapid transport by flight crews to tertiary care centers with a higher level of medical capabilities. An impact because of helicopters on survival has been well-documented for trauma patients. Assessing usage for other critical care patients remains to be delineated further.

Outcome in an urban pediatric trauma system with unified prehospital emergency medical services care

HYPOTHESIS: Pediatric mortality is predicted by age, presence of head trauma, head trauma with a low Glasgow Coma Scale (GCS) score, a low Pediatric Trauma Score (PTS), and transport directly to a pediatric trauma center. POPULATION: Studied were 1,429 patients younger than 16 years old admitted to or declared dead on arrival (DOA) in a pediatric trauma center from January through October, 1988. The trauma system, which served 3-million persons, included six pediatric trauma centers. METHODS: Data were obtained by a retrospective review of summary statistics provided to the Chicago Department of Health by the pediatric trauma centers. RESULTS: Overall mortality was 4.8% (68 of 1429); 32 of the patients who died (47.1%) were DOA. The in-hospital mortality rate was 2.6%. Head injury was the principal diagnosis in 46.2% of admissions and was a factor in 72.2% of hospital deaths. The mortality rate was 20.3% in children with a GCS < or = 10 and 0.4% when the GCS was > 10 (odds ratio [OR] = 67.0, 95% CI = 15.0-417.4). When the PTS was < or = 5, mortality was 25.6%; with a PTS > 5, the mortality was 0.2% (OR = 420.7, 95% CI = 99.3-2,520). Although transfers to a pediatric trauma center accounted for 73.6% of admissions, direct field triage to a pediatric trauma center was associated with a 3.2 times greater mortality risk (95% CI = 1.58-6.59). Mortality rates were equal for all age groups. Pediatric trauma center volume did not influence mortality rates. CONCLUSIONS: Head injury and death occur in all age groups, suggesting the need for broad prevention strategies. Specific GCS and PTS values that predict mortality can be used in emergency medical services (EMS) triage protocols. Although the high proportion of transfers mandates systemwide transfer protocols, the lower mortality in these patients suggests appropriate EMS field triage. These factors should be considered as states develop pediatric trauma systems.

Ethical conflicts in prehospital emergency care

This article analyses and presents a survey of ethical conflicts in prehospital emergency care. The results are based on six focus group interviews with 29 registered nurses and paramedics working in prehospital emergency care at three different locations: a small town, a part of a major city and a sparsely populated area. Ethical conflict was found to arise in 10 different nodes of conflict: the patient/carer relationship, the patient's self-determination, the patient's best interest, the carer's professional ideals, the carer's professional role and self-identity, significant others and bystanders, other care professionals, organizational structure and resource management, societal ideals, and other professionals. It is often argued that prehospital care is unique in comparison with other forms of care. However, in this article we do not find support for the idea that ethical conflicts occurring in prehospital care are unique, even if some may be more common in this context.     

Application of the emergency medical services trigger tool to measure adverse events in prehospital emergency care: a time series analysis

Background

Emergency Care has previously been identified as an area of significant concern regarding the prevalence of Adverse Events (AEs). However, the majority of this focus has been on the in-hospital setting, with little understanding of the identification and incidence of AEs in the prehospital environment.

Method

The early development and testing of Emergency Medical Services (EMS) specific triggers for the identification of AEs and Harm has been previously described. To operationalise the Emergency Medical Services Trigger Tool (EMSTT), the processes developed by the Institute for Healthcare Improvement for use with the Global Trigger Tool were adapted to a prehospital emergency care setting. These were then applied using a stepwise approach to the analysis of 36 consecutive samples of patient care records over an 18-month period (n =?710). Inter-rater reliability was measured for each trigger item and level of Harm classification. Total Triggers per 10,000 Patient Encounters, AEs per 10,000 Patient Encounters and Harm per 10,000 Patient Encounters were measured. All measures were plotted on Statistical Process Control Charts.

Results

There was a high level of inter-rater agreement across all items (range: 85.6–100%). The EMSTT found an average rate of 8.20 Triggers per 10,000 Patient Encounters, 2.48 AEs per 10,000 Patient Encounters and 0.34 Harm events per 10,000 Patient Encounters. Three triggers: Change in Systolic Blood Pressure Greater Than 20%; Temp?>?38 °C without subsequent reduction; and SpO₂ <?94% without supplemental Oxygen or SpO₂ <?85% without assisted ventilation accounted for 93% (n =?180) of the triggers found throughout the longitudinal analysis.

Discussion

With sufficient focus on implementation and data collection, as well as the inclusion of a contextually relevant system for classifying AE/Harm, the EMSTT represents a potentially successful strategy towards identifying the rate of AEs within EMS across a large patient population with limited commitment of time and resources.

     

Few emergency medical services patients with lower-extremity fractures receive prehospital analgesia

Previous literature has identified prehospital pain management as an important emergency medical services (EMS) function, and few patients transported by EMS with musculoskeletal injuries receive prehospital analgesia (PA). Objectives. 1) To describe the frequency with which EMS patients with lower-extremity and hip fracture receive prehospital and emergency department (ED) analgesia; 2) to describe EMS and patient factors that may affect administration of PA to these patients; and 3) to describe the time interval between EMS and ED medication administrations. Methods. This was a four-month (April to July 2000) retrospective study of patients with a final hospital diagnosis of hip or lower-extremity fracture who were transported by EMS to a single suburban community hospital. Data including patient demographics, fracture type, EMS response, and treatment characteristics were abstracted from review of EMS and ED records. Patients who had ankle fractures, had multiple traumatic injuries, were under the age of 18 years, or did not have fractures were excluded. Results. One hundred twenty-four patients met inclusion criteria. A basic life support (BLS)-only response was provided to 20 (16.0%). Another 38 (38.4%) received an advanced life support (ALS) response and were triaged to BLS transport. Of all the patients, 22 (18.3%) received PA. Patients who received PA were younger (64.0 vs. 77.3 years, p < 0.001) and more likely to have a lower-extremity fracture other than a hip fracture (31.8% vs. 10.7%, p < 0.004). Of all patients, 113 (91.1%) received ED analgesia. Patients received analgesia from EMS almost 2.0 hours sooner that in the ED (mean 28.4 ± 36 min vs. 146 ± 74 min after EMS scene arrival, p < 0.001). Conclusion. A minority of the study group received PA. Older patients and patients with hip fracture are less likely to receive PA. It is unclear whether current EMS system design may adversely impact administration of PA. Further work is needed to clarify whether patient need or EMS practice patterns result in low rates of PA.

Predictors of demand for emergency prehospital care: an Australian study

INTRODUCTION: Determining the predictors of demand for emergency prehospital care can assist ambulance services in undertaking policy and planning activities. HYPOTHESIS: Demand for prehospital care can be explained by demographic, health status, and economic determinants. METHODS: The study used a cross-sectional design to investigate the association of demographic, health status, and insurance factors with the use of prehospital, ambulance care. Core data items including age, gender, marital status, country of origin, triage score, diagnosis, time of presentation, method of arrival, and patient disposition were collected for every patient who presented at the Emergency Department of the study hospital over a four-month period. Ambulance usage was analysed using Poisson regression. RESULTS: For the 10,229 patients surveyed, only a small number were triaged as having the highest level of urgent medical need (0.8%), but the majority of these used prehospital emergency medical care (90.2%). Predictors of ambulance use included age > 65 years (Prevalence Ratio [PR] = 2.92; 95% confidence interval [CI]: 2.35-3.63), being married or in a de-facto relationship (PR = 0.69; 95% CI: 0.60-0.79) or divorced, separated, or widowed (PR = 0.83; 95% CI: 0.70-0.98), triage score level 1 or 2 (PR = 1.95; 95% CI: 1.68-2.28), or triage score level 3 (PR = 1.54; 95% CI: 1.38-1.72), diagnosis involving either mental (PR = 4.29; 95% CI: 1.84-10.01), nervous (PR = 2.74; 95% CI: 1.19-6.31) or trauma (PR = 2.33; 95% CI: 1.03-5.27) conditions, and insurance status (PR = 1.54; 95% CI: 1.40-1.71). Ethnicity, gender, and time of day were not associated with usage. CONCLUSION: Demand for ambulance services can be predicted by a number of demographic, medical status, and insurance variables. Age and triage levels are key influences on demand for ambulance services. Ambulance insurance status provides an economic incentive to use ambulance services regardless of the urgency of the medical condition.     

Prehospital care: emergency medical services

Emergency medical services are becoming an increasingly important aspect of health care delivery. Prehospital care providers, termed paramedics, follow established protocols and work under a medical director in implementing treatment on the scene. Special problems include the physician on the scene, issues of consent and liability, and the treatment of terminally ill patients.
