Can the critically ill consent to participation in commercial television programmes? An Australian prehospital and emergency medicine perspective

The fly‐on‐the‐wall medical documentary is a popular television phenomenon. When patients can give appropriate consent to filming, the final product can be both educational for the public and rewarding for its subjects. However, in the dynamic world of emergency and prehospital medicine, consenting critically ill patients before filming is a significant challenge. The main barriers to gaining valid consent in the field and in the ED are limited time to inform the patient and the diminished capacity of the sick patient. Although there is an argument that involvement in a commercial film might be beneficial to several parties, including the patient, these benefits do not amount to therapeutic necessity if prior consent is not obtainable. Despite this, we still see acutely incapacitated patients featured in some television programmes. In these cases, the conventional process of consent might be being sidestepped in order to obtain permission for broadcast retrospectively. This alternative process fails to recognise that incapacitated patients require protection from an invasion of privacy that occurs when a crew is filming their resuscitations. This harm has already occurred by the time consent is sought. Ultimate responsibility for defending the patients' interests during their medical treatment rests with the medical practitioner. We argue that filming a patient without prior consent in both the prehospital and emergency environment is ethically unsound: it threatens trust in the healthcare relationship and might compromise the patient's dignity and privacy. Robust guidelines should be developed for all healthcare professionals who engage with commercial film crews.     

Ethical challenges in emergency medical services. A special contribution of the Ethics Committee, National Association of Emergency Medical Services Physicians

Patient autonomy, beneficence, and justice are the fundamental ethical principles of an emergency medical service. Ethical conflicts are present in the daily practice of prehospital care. These conflicts surround issues of resuscitation, futile therapy, consent, and refusal of care, duty, and confidentiality. Emergency medical services must remain fair and equitable, equally available to those it is designed to serve, regardless of the patient's social or economic status. Establishing priorities for patient care is dictated by medical and operational concerns. Education and information regarding ethical issues are important for the providers of prehospital medical care as well as the medical director. Policies and protocols must continue to be developed to address requests to limit resuscitation, such as refusal of care and patient confidentiality. Policies should be developed in conjunction with experienced legal advice. Current training does not equip even the most advanced prehospital care provider to deal easily with every potential situation. Many learn by experience, some are guided by clear policy. Ideally, medical control personnel will be educated, interested, and available to address dilemmas which arise. Where possible, policies and procedures should be developed to address ethical issues which are likely to be faced by EMS personnel.     

Management of an extremely premature infant in the out-of-hospital environment

The rate of premature infant mortality has decreased over the last several decades, with an accompanying decrease in the gestational age of premature infants who survive to hospital discharge. Emergency medical services (EMS) providers are sometimes called to provide prehospital care for infants born at the edge of viability. Such extremely premature infants (EPIs) present medical and ethical challenges. In this case report, we describe an infant born at 24 weeks into a toilet by a mother who thought she had miscarried. The EMS providers evaluated the infant as nonviable and placed him in a plastic bag for transport to a local emergency department (ED). The ED staff found the infant to have a bradycardic rhythm, initiated resuscitation, and admitted him to the neonatal intensive care unit. The infant died seven days later. We review the literature for recommendations in resuscitation of EPIs and discuss the ethics regarding their management in the prehospital setting.     

Intubation endotrachéale aux urgences par les urgentistes : contre

Considering that endotracheal intubations for emergency airway management in prehospital settings has mandatorily to be mastered by emergency physicians, indoor, in emergency departments and in non-immediatly life-threatening situations, this concept is less obvious. Nevertheless, it is worth being put in prospect with its medico-legal (who is the most experimented physician present in the hospital?), political (interface between different medical specialities, patients’outcome?) and ethical (indications of endotracheal intubations in some situations?) aspects. Training programs, abilities and collegiate human relationships are obviously the response to the asked question rather than professional claims.

An analysis of dilemmas posed by prehospital DNR orders

This article briefly recounts the development of the prehospital do-not-resuscitate (DNR) order and indicates certain situations, such as a choking episode or a suicide attempt, in which the presence of a DNR order may provoke a moral dilemma for the emergency medical technician as to whether or not the patient should be treated. An ethical analysis of this question is performed and concludes that resuscitative treatment is ethical and mandatory.     

Retrospective observational case-control study comparing prehospital thrombolytic therapy for ST-elevation myocardial infarction with in-hospital thrombolytic therapy for patients from same area

Design: Retrospective observational case-control study comparing patients with suspected acute myocardial infarction (AMI) treated with thrombolytic therapy in the prehospital environment with patients treated in hospital. Setting: Wyre Forest District and Worcestershire Royal Hospital, UK. Participants: (A) All patients who received prehospital thrombolytic therapy for suspected AMI accompanied by electrocardiographic features considered diagnostic. (B) Patients who received thrombolytic therapy after arrival at hospital for the same indication, matched with group A by age, gender and postcode. Main outcome measures: 1. Call to needle time 2. Percentage of patients treated within one hour of calling for medical help 3. Appropriateness of thrombolytic therapy 4. Safety of thrombolytic therapy Results: 1. The median call to needle time for patients treated before arriving in hospital (n = 27) was 40 minutes with an inter-quartile range 25–112 (mean 43 minutes). Patients from the same area who were treated in hospital (n = 27) had a median time of 106 minutes with an inter-quartile range 50–285 (mean 126 minutes). This represents a median time saved by prehospital treatment of 66 minutes. 2. 60 minutes after medical contact, 96 % of patients treated before arrival in hospital had received thrombolytic therapy; this compares with 4% of patients from similar areas treated in hospital. 3. Myocardial infarction was confirmed in 92% (25/27) of patients who received prehospital thrombolytic therapy and similarly 92% (25/27) of those given in-hospital thrombolytic therapy. 4. No major bleeding occurred in either group. Group A suffered fewer in-hospital deaths than group B (1 versus 4). Cardiogenic shock (3 patients) and ventricular arrhythmia (5 patients) were seen only in group B. Conclusion: Paramedic-delivered thrombolytic therapy can be delivered appropriately, safely, and effectively. Time gains are substantial and can meet the national targets for early thrombolytic therapy in the majority of patients.     

Prehospital response to respiratory distress by the public ambulance system in a Ukrainian city

BACKGROUND: The capability of the public ambulance system in Ukraine to address urgent medical complaints in a prehospital environment is unknown. Evaluation using reliable sources of patient data is needed to provide insight into current treatments and outcomes. METHODS: We obtained access to de-identified computer records from the emergency medical services (EMS) dispatch center in Poltava, a medium-sized city in central Ukraine. Covering a five-month period, we retrieved data for urgent calls with a patient complaint of respiratory distress. We evaluated ambulance response and treatment times, field diagnoses, and patient disposition, and analyzed factors related to fatal outcomes. RESULTS: Over the five-month period of the study, 2,029 urgent calls for respiratory distress were made to the Poltava EMS dispatch center. A physician-led ambulance typically responded within 10 minutes. Seventy-seven percent of patients were treated and released, twenty percent were taken to hospital, and three percent died in the prehospital phase. On univariate analysis, age over 60 and altered mental status at the time of the call were strongly associated with a fatal outcome. CONCLUSION: The EMS dispatch center in a medium-sized city in Ukraine has adequate organizational infrastructure to ensure that a physician-led public ambulance responds rapidly to complaints of respiratory distress. That EMS system was able to manage most patients without requiring hospital admission. However, a prehospital fatality rate of three percent suggests that further research is warranted to determine training, equipment, or procedural needs of the public ambulance system to manage urgent medical conditions.

Do-not-resuscitate orders. Where are they in the prehospital setting?

Without a well-functioning, prehospital, do-not-resuscitate (DNR) system in place, emergency medical service (EMS) providers must resuscitate all patients who access the system, regardless of the patients' wishes and regardless of what makes ethical or economic sense. In lieu of valid documentation, it is not appropriate to withhold resuscitative measures in this critical, time-dependent situation. In order to help EMS systems implement functional prehospital DNR protocols, this paper reviews the state-of-the-art of prehospital DNR including the issues to consider when designing such a system and a discussion of the features of some of the existing systems. This review includes: 1) the basis and requirements of a DNR system; 2) legal and physical forms for DNR orders; 3) eligibility for DNR status; 4) reversal of DNR orders; and 5) inappropriate use of EMS systems for DNR patients. Finally, a more general discussion of overall resource utilization in prehospital resuscitations is presented to emphasize that implementing prehospital DNR systems is only one piece of a larger issue.     

Mass casualty incident. Integration with prehospital care

Mass casualty incident involves the use of limited resources for multiple casualties. The emergency physician must be familiar with both prehospital and hospital plans for mass casualty care in order to facilitate optimal care and to maintain the continuum from field care to definitive treatment. It is essential that the emergency physician become involved in the disaster planning processes to ensure that the victims receive the best care available under the circumstances and that the safety and emotional well-being of both prehospital and hospital personnel are assured. Emergency physicians involved in prehospital care should be certain that the local EMS system has adequate training and chances to update their skills and knowledge. Disaster drills of the EMS system are excellent ways to practice, to identify weaknesses, and for preplanning to enhance disaster medical care.     

Facilities and regionalization--emergency medical services systems

Advanced life support and the modern EMS system were born out of the hope that by extending hospital emergency facilities outside the bounds of the hospital, earlier and more intensive care could be provided to those patients requiring it. EMS systems have since left the nest and only recently, following a turbulent adolescence, is prehospital care returning as a partner with the medical facilities and physicians that presided over their modern origins. The next decade will see the continuing trend toward hospitals and practitioners regaining some influence in the design and direction of prehospital care.     

Prehospital system delay in patients with ST-segment elevation myocardial infarction in Singapore

BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction(STEMI)improves outcomes. System delay is that between first medical contact and reperfusion therapy,comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore.METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services(EMS),ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique.RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5minutes(interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes(IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes(IQR=1.30, 22.13); between arrival-at- and departurefrom-patient-location was 13.12 minutes(IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes(IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulancedispatch and arrival-at-patient-location was shorter(5.75 vs. 9.37 minutes, P0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter(10.78 vs.14.37 minutes, P0.01).CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care.     

Successful Management of Excited Delirium Syndrome with Prehospital Ketamine: Two Case Examples

Abstract

Excited delirium syndrome (ExDS) is a medical emergency usually presenting first in the prehospital environment. Untreated ExDS is associated with a high mortality rate and is gaining recognition within organized medicine as an emerging public safety problem. It is highly associated with male gender, middle age, chronic illicit stimulant abuse, and mental illness. Management of ExDS often begins in the field when first responders, law enforcement personnel, and emergency medical services (EMS) personnel respond to requests from witnesses who observe subjects exhibiting bizarre, agitated behavior. Although appropriate prehospital management of subjects with ExDS is still under study, there is increasing awareness of the danger of untreated ExDS, and the danger associated with the need for subject restraint, whether physical or chemical. We describe two ExDS patients who were successfully chemically restrained with ketamine in the prehospital environment, and who had good outcomes without complication. These are among the first case reports in the literature of ExDS survival without complication using this novel prehospital sedation management protocol. This strategy bears further study and surveillance by the prehospital care community for evaluation of side effects and unintended complications.     

Analysis of Prehospital Documentation of Injury-Related Pain Assessment and Analgesic Administration on the Contemporary Battlefield

In addition to life-saving interventions, the assessment of pain and subsequent administration of analgesia are primary benchmarks for quality emergency medical services care which should be documented and analyzed. Analyze US combat casualty data from the Department of Defense Trauma Registry (DoDTR) with a primary focus on prehospital pain assessment, analgesic administration and documentation. Retrospective cohort study of battlefield prehospital and hospital casualty data were abstracted by DoDTR from available records from 1 September 2007 through 30 June 2011. Data included demographics; injury mechanism; prehospital and initial combat hospital pain assessment documented by standard 0-to-10 numeric rating scale; analgesics administered; and survival outcome. Records were available for 8,913 casualties (median ISS of 5 [IQR 2 to 10]; 98.7% survived). Prehospital analgesic administration was documented for 1,313 cases (15%). Prehospital pain assessment was recorded for 581 cases (7%; median pain score 6 [IQR 3 to 8]), hospital pain assessment was recorded for 5,007 cases (56%; median pain score5 [CI95% 3 to 8]), and 409 cases (5%) had both prehospital and hospital pain assessments that could be paired. In this paired group, 49.1% (201/409) had alleviation of pain evidenced by a decrease in pain score (median 4,, IQR 2 to 5); 23.5% (96/409) had worsening of pain evidenced by an increase in pain score (median 3, CI95 2.8 to 3.7, IQR 1 to 5); 27.4% (112/409) had no change; and the overall difference was an average decrease in pain score of 1.1 (median 0, IQR 0 to 3, p < 0.01). Time-series analysis showed modest increases in prehospital and hospital pain assessment documentation and prehospital analgesic documentation. Our study demonstrates that prehospital pain assessment, management, and documentation remain primary targets for performance improvement on the battlefield. Results of paired prehospital to hospital pain scores and time-series analysis demonstrate both feasibility and benefit of prehospital analgesics. Future efforts must also include an expansion of the prehospital battlefield analgesic formulary.     

Extending the role of lactate measurement into the prehospital environment

Early identification of haemodynamic shock is widely acknowledged as a vital step towards improving survival. A report in the previous issue of Critical Care describes the relationship between lactate concentrations in blood samples analysed in the prehospital environment and subsequent hospital mortality. These preliminary data indicate a promising avenue of research into the treatment of haemodynamic shock. Larger observational and interventional trials are needed to confirm the clinical value of serum lactate measurement in the prehospital environment.     

Prehospital triage in emergency medical services system: A scoping review

BackgroundDuring the prehospital phase, paramedics consider patients’ condition according to illness, injury, disease and decide on transport to an appropriate hospital according to severity. This can affect patient survival and treatment prognosis, because despite intervention at this early stage, problems such as incorrect triage of severity and inappropriate hospital selection may occur, indicating a need for improvement in the process.PurposeThe aim of this review is to identify the overall trend of research conducted on prehospital triage by analyzing the emergency medical services system and presenting future studies to practitioners and researchers.MethodsA scoping review was conducted of existing literature on research trends in relation to prehospital triage. The studies reviewed were identified using electronic databases such as PubMed, CINAHL, Cochrane Library, Web of Science, and Scopus.ResultsNinety-eight documents were finally selected and analyzed that focused on prehospital triage status, process accuracy, tools, guidelines, and protocols.ConclusionResearch is proposed that focuses on various non-traumatic patient types, prehospital triage education, and development of training programs to reduce errors in the emergency patient handover process between prehospital and hospital health professionals and to improve patient health and quality of life.     

The prehospital treatment of status epilepticus (PHTSE) study: design and methodology

Status epilepticus is a neurological emergency that is typically first encountered and managed in the prehospital environment. Although aggressive pharmacological treatment of status epilepticus is well established in the emergency department and hospital settings, the relative risks and benefits of active therapy for status epilepticus in the prehospital setting are not known. The Prehospital Treatment of Status Epilepticus (PHTSE) study is a prospective, randomized, double-blind, placebo-controlled study designed to address the following aims: (1) to determine whether administration of benzodiazepines by paramedics is an effective and safe means of treating status epilepticus in the prehospital setting and whether this therapy influences longer-term patient outcome, (2) to determine whether lorazepam is superior to diazepam for the treatment of status epilepticus in the prehospital setting, and (3) to determine whether control of status epilepticus prior to arrival to the emergency department influences patient disposition. The initial phase of the PHTSE study began in January 1994 and was completed in February 1999 after the successful enrollment of 205 patients into the three treatment arms. In this paper, we describe the rationale for the conceptualization of the study and details of the study design and methodology, and emphasize some aspects of study implementation that are unique to research involving the emergency medical system.     

Prehospital intravenous access and fluid resuscitation in severe sepsis: an observational cohort study

Introduction

Prompt treatment of severe sepsis in the Emergency Department reduces deaths, but the role of prehospital fluid resuscitation is unknown. We sought to determine the risk-adjusted association between prehospital fluid administration and hospital mortality among emergency medical services (EMS) patients admitted with severe sepsis.

Methods

We performed a prospective, observational study of patients hospitalized with severe sepsis on admission among 45,394 adult EMS encounters taken to 15 hospitals from 11/2009 to 12/2010 by a two-tier EMS system in King County, Washington. The region mandated recording of prehospital intravenous catheter and fluid administration in prehospital records, along with detailed demographic, incident, physiologic, and hospital adjustment variables. We determined the effect of prehospital intravenous catheter or fluid versus no catheter or fluid on all-cause mortality using multivariable logistic regression.

Results

Of all encounters, 1,350 met criteria for severe sepsis on admission, of whom 205 (15%) died by hospital discharge, 312 (23%) received prehospital intravenous fluid, 90 (7%) received a prehospital catheter alone and 948 (70%) did not receive catheter or fluid. EMS administered a median prehospital fluid volume of 500 mL (interquartile range (IQR): 200, 1000 mL). In adjusted models, the administration of any prehospital fluid was associated with reduced hospital mortality (Odds ratio =0.46; 95% Confidence interval: 0.23, 0.88; P =0.02) compared to no prehospital fluid. The odds of hospital mortality were also lower among severe sepsis patients treated with prehospital intravenous catheter alone (Odds ratio =0.3; 95% Confidence interval: 0.17 to 0.57; P <0.01).

Conclusions

In a population-based study, the administration of prehospital fluid and placement of intravenous access were associated with decreased odds of hospital mortality compared with no prehospital catheter or fluid.
