RESUMEN

A decade on from the first positive thrombectomy trials, hyperacute therapies for ischemic stroke continue to rapidly advance. Effective treatments remain limited to reperfusion, although several cytoprotective approaches continue to be investigated. Intravenous fibrinolytics are now demonstrated to be beneficial up to 24 h in patients selected using perfusion imaging, but their role in patients with non-disabling symptoms appears very limited. Tenecteplase is superior to alteplase in meta-analysis of the latest trials, and adjuvant thrombolytics are an area of active investigation. Endovascular thrombectomy is beneficial in a wide range of anterior and posterior circulation large vessel occlusions up to 24 h after onset with the more distal occlusions, mild presentations, and >24 h window being the main frontiers to be tested in ongoing trials. Imaging parameters are prognostic but appear not to modify the relative treatment benefit of thrombectomy versus standard medical care. Therefore, deciding who not to treat with thrombectomy is a key clinical challenge that requires careful but rapid integration of clinical, imaging, and patient preference considerations. Systems of care to accelerate delivery of these highly effective therapies will maximize benefits for the greatest number of patients with stroke.

RESUMEN

Objectives: To develop an easy-to-use severity scoring tool for prehospital triage of patients infected by the coronavirus disease-2019 in resource-limited settings. METHODS: The cohort study was conducted at a tertiary care hospital in Karachi, from August to September 2020, and comprised adult patients of either gender who tested positive for coronavirus disease-2019 on real-time polymerase chain reaction. The scoring system and categorisation were based on validated scales for the detection of pneumonia and opinions from pulmonologists. Data was analysed using SPSS 19. RESULTS: Of the 206 participants, 100(48.5%) were in-patients and 106(51.5%) were out-patients. There were 144(69.9%) males and 62(30.1%) females with an overall mean age of 48.4±16.2 years. After categorisation based on severity, significantly higher number of in-patients were found to be in categories III and IV (p<0.05). CONCLUSIONS: The severity scoring tool could effectively help classify coronavirus disease-2019 patients into mild, moderate and severe cases.

RESUMEN

AIMS: Patients with suspected non-ST-segment elevation acute coronary syndrome (NSTE-ACS) are routinely transferred to the emergency department (ED). A clinical risk score with point-of-care (POC) troponin measurement might enable ambulance paramedics to identify low-risk patients in whom ED evaluation is unnecessary. The aim was to assess safety and healthcare costs of a pre-hospital rule-out strategy using a POC troponin measurement in low-risk suspected NSTE-ACS patients. METHODS AND RESULTS: This investigator-initiated, randomized clinical trial was conducted in five ambulance regions in the Netherlands. Suspected NSTE-ACS patients with HEAR (History, ECG, Age, Risk factors) score ≤3 were randomized to pre-hospital rule-out with POC troponin measurement or direct transfer to the ED. The sample size calculation was based on the primary outcome of 30-day healthcare costs. Secondary outcome was safety, defined as 30-day major adverse cardiac events (MACE), consisting of ACS, unplanned revascularization or all-cause death. : A total of 863 participants were randomized. Healthcare costs were significantly lower in the pre-hospital strategy (€1349 ± €2051 vs. €1960 ± €1808) with a mean difference of €611 [95% confidence interval (CI): 353-869; P < 0.001]. In the total population, MACE were comparable between groups [3.9% (17/434) in pre-hospital strategy vs. 3.7% (16/429) in ED strategy; P = 0.89]. In the ruled-out ACS population, MACE were very low [0.5% (2/419) vs. 1.0% (4/417)], with a risk difference of -0.5% (95% CI -1.6%-0.7%; P = 0.41) in favour of the pre-hospital strategy. CONCLUSION: Pre-hospital rule-out of ACS with a POC troponin measurement in low-risk patients significantly reduces healthcare costs while incidence of MACE was low in both strategies.

RESUMEN

BACKGROUND: Responsive and efficient emergency medical services (EMS) require accurate telephone triage. In Finland, such services are provided by Emergency Response Centre Agency (ERC Agency). In 2018, a new Finnish computer-assisted emergency dispatch system was introduced: the Emergency Response Integrated Common Authorities (ERICA). After the introduction of ERICA, the appropriateness of EMS dispatch has not been investigated yet. The study´s objective is to determine the consistency between the priority triage of the emergency medical dispatcher (EMD) and the on-scene priority assessment of the EMS, and whether the priority assessment consistency varied among the dispatch categories. METHODS: This was a prospective register-based study. All EMS dispatches registered in the Tampere University Hospital area from 1 August 2021 to 31 August 2021 were analysed. The EMD's mission priority triaged during the emergency call was compared with the on-scene EMS's assessment of the priority, derived from the pre-set criteria. The test performance levels were measured from the crosstabulation of true or false positive and negative values of the priority assessment. Statistical significance was analysed using the chi-square test and the Kruskal-Wallis H test, and p-values < 0.05 were considered significant. RESULTS: Of the 6416 EMS dispatches analysed in this study, 36% (2341) were urgent according to the EMD's dispatch priority, and of these, only 29% (688) were urgent according to the EMS criteria. On the other hand, 64% (4075) of the dispatches were non-urgent according to the EMD's dispatch priority, of which 97% (3949) were non-urgent according to the EMS criteria. Moreover, there were differences between the EMD and EMS priority assessments among the dispatch categories (p < 0.001). The overall efficiency was 72%, sensitivity 85%, specificity 71%, positive predictive value 29%, and negative predictive value 97%. CONCLUSION: While the EMD recognised the non-urgent dispatches with high consistency with the EMS criteria, most of the EMD's urgent dispatches were not urgent according to the same criteria. This may diminish the availability of the EMS for more urgent missions. Thus, measures are needed to ensure more accurate and therefore, more efficient use of EMS resources in the future.

RESUMEN

OBJECTIVE: To determine the influence of intoxication on the pre-hospital recognition of severely head-injured patients by Emergency Medical Services (EMS) professionals and to investigate the relationship between suspected alcohol intoxication and severe head injury. METHODS: This multi-center, retrospective, cohort study included trauma patients, aged ≥ 16 years, transported by an ambulance of the Regional Ambulance Facility Utrecht to any emergency department in the participating trauma regions. RESULTS: Between January 1, 2015 and December 31, 2017, 19,206 patients were included, of whom 1167 (6.0%) were suspected to have a severe head injury in the field, and 623 (3.2%) were diagnosed with such an injury at the hospital. These injuries were less frequently recognized in patients with a GCS ≥ 13 than in patients with a GCS < 13 (25.0% vs. 76.2%). Patients suspected to be intoxicated had a higher chance to suffer from severe head injury (OR 1.42, 95%-CI 1.22-1.65) and were recognized slightly more often (45.3% vs. 40.2%). CONCLUSION: Severe head injuries are difficult to recognize in the field, especially in patients without a decreased GCS. Suspicion of alcohol intoxication did not seem to influence pre-hospital injury recognition, as it possibly makes a severe head injury harder to recognize and simultaneously raises caution for a severe injury.

RESUMEN

BACKGROUND: The requirement concerning formal education for emergency medical dispatcher (EMD) is debated and varies, both nationally and internationally. There are few studies on the outcomes of emergency medical dispatching in relation to professional background. This study aimed to compare calls handled by an EMD with and without support by a registered nurse (RN), with respect to priority level, accuracy, and medical condition. METHODS: A retrospective observational study, performed on registry data from specific regions during 2015. The ambulance personnel's first assessment of the priority level and medical condition was used as the reference standard. Outcomes were: the proportion of calls dispatched with a priority in concordance with the ambulance personnel's assessment; over- and undertriage; the proportion of most adverse over- and undertriage; sensitivity, specificity and predictive values for each of the ambulance priorities; proportion of calls dispatched with a medical condition in concordance with the ambulance personnel's assessment. Proportions were reported with 95% confidence intervals. χ2-test was used for comparisons. P-levels < 0.05 were regarded as significant. RESULTS: A total of 25,025 calls were included (EMD n = 23,723, EMD + RN n = 1302). Analyses relating to priority and medical condition were performed on 23,503 and 21,881 calls, respectively. A dispatched priority in concordance with the ambulance personnel's assessment were: EMD n = 11,319 (50.7%) and EMD + RN n = 481 (41.5%) (p < 0.01). The proportion of overtriage was equal for both groups: EMD n = 5904, EMD + RN n = 306, (26.4%) p = 0.25). The proportion of undertriage for each group was: EMD n = 5122 (22.9%) and EMD + RN n = 371 (32.0%) (p < 0.01). Sensitivity for the most urgent priority was 54.6% for EMD, compared to 29.6% for EMD + RN (p < 0.01), and specificity was 67.3% and 84.8% (p < 0.01) respectively. A dispatched medical condition in concordance with the ambulance personnel's assessment were: EMD n = 13,785 (66.4%) and EMD + RN n = 697 (62.2%) (p = 0.01). CONCLUSIONS: A higher precision of emergency medical dispatching was not observed when the EMD was supported by an RN. How patient safety is affected by the observed divergence in dispatched priorities is an area for future research.

RESUMEN

Effective triage is critical to ensure patients suffering major trauma are identified and access a pathway to definitive major trauma care, typically provided in a major trauma centre as part of an established major trauma system. The pre-hospital triage of trauma patients often relies upon the use of major trauma triage tools; this commentary critically appraises a recent systematic review which sought to evaluate and compare the accuracy of pre-hospital triage tools for major trauma.

RESUMEN

BACKGROUND: Pre-hospital identification of major trauma in elderly patients is key for delivery of optimal care, however triage of this group is challenging. Elderly-specific triage criteria may be valuable. This systematic review aimed to summarise the published pre-hospital elderly-specific trauma triage tools and evaluate their sensitivity and specificity and associated clinical outcomes. METHODS: MEDLINE and EMBASE databases were searched using predetermined criteria (PROSPERO: CRD42019140879). Two authors independently assessed search results, performed data extraction, risk of bias and quality assessments following the Grading of Recommendations, Assessment, Development and Evaluation system. RESULTS: 801 articles were screened and 11 studies met eligibility criteria, including 1,332,300 patients from exclusively USA populations. There were eight unique elderly-specific triage criteria reported. Most studies retrospectively applied criteria to trauma databases, with few reporting real-world application. The Ohio Geriatric Triage Criteria was reported in three studies. Age cut-off ranged from 55 to 70 years with ≥ 65 most frequently reported. All reported existing adult criteria with modified physiological parameters using higher thresholds for systolic blood pressure and Glasgow coma scale, although the values used varied. Three criteria added co-morbidity or anti-coagulant/anti-platelet use considerations. Modifications to anatomical or mechanism of injury factors were used by only one triage criteria. Criteria sensitivity ranged from 44 to 93%, with a median of 86.3%, whilst specificity was generally poor (median 54%). Scant real-world data showed an increase in patients meeting triage criteria, but minimal changes to patient transport destination and mortality. All studies were at risk of bias and assessed of "very low" or "low" quality. CONCLUSIONS: There are several published elderly-specific pre-hospital trauma triage tools in clinical practice, all developed and employed in the USA. Consensus exists for higher thresholds for physiological parameters, however there was variability in age-cut offs, triage criteria content, and tool sensitivity and specificity. Although sensitivity was improved over corresponding 'adult' criteria, specificity remained poor. There is a paucity of published real-world data examining the effect on patient care and clinical outcomes of elderly-specific triage criteria. There is uncertainty over the optimal elderly triage tool and further study is required to better inform practice and improve patient outcomes.

RESUMEN

BACKGROUND: A large proportion of patients who call 112 in Sweden do so because of pain. The purpose of this study was to compare three of the most common types of pain presented by the patients: chest pain, abdominal pain and hip injury, in terms of initial assessment, intensity, treatment and effect of treatment. The overall rationale was to evaluate whether the early assessment and treatment of pain in the pre-hospital setting is optimal or whether there is room for improvement. METHODS: Observational study during 2016 including 1234 patients triaged to chest pain, abdominal pain and hip injury by the Emergency Medical Services (EMS) in Gothenburg, Sweden. RESULTS: Severe pain on the arrival of the EMS was described by 39% of patients with a hip injury, 27% with abdominal pain and 15% with chest pain. Analgesics were given to 58% of patients with a hip injury, 35% with chest pain and 34% with abdominal pain. A lower intensity of pain at re-evaluation was observed in 80% of patients with a hip injury, 57% with chest pain and 43% with abdominal pain. Administration of analgesics increased with the duration of pre-hospital care time in all three groups. CONCLUSIONS: Patients with a hip injury had the most severe pain and they received most pain-relieving medication. Overall, a relatively small proportion of patients with pain received pain-relieving medication and there appears to be an extensive room for improvement.

RESUMEN

BACKGROUND: In acute stroke, large vessel occlusion (LVO) should be promptly identified to guide patient's transportation directly to comprehensive stroke centers (CSC) for mechanical thrombectomy (MT). In many cases, prehospital multi-parameter scores are used by trained emergency teams to identify patients with high probability of LVO. However, in several countries, the first aid organization without intervention of skilled staff precludes the on-site use of such scores. Here, we assessed the accuracy of LVO prediction using a single parameter (i.e. complete hemiplegia) obtained by bystander's telephone-based witnessing. PATIENTS AND METHODS: This observational, single-center study included consecutive patients who underwent intravenous thrombolysis at the primary stroke center and/or were directly transferred to a CSC for MT, from January 1, 2015 to March 1, 2020. We defined two groups: patients with initial hemiplegia (no movement in one arm and leg and facial palsy) and patients without initial hemiplegia, on the basis of a bystander's witnessing. RESULTS: During the study time, 874 patients were included [mean age 73 years (SD 13.8), 56.7% men], 320 with initial hemiplegia and 554 without. The specificity of the hemiplegia criterion to predict LVO was 0.88, but its sensitivity was only 0.53. CONCLUSION: Our results suggest that the presence of hemiplegia as witnessed by a bystander can predict LVO with high specificity. This single criterion could be used for decision-making about direct transfer to CSC for MT when the absence of emergency skilled staff precludes the patient's on-site assessment, especially in regions distant from a CSC.

RESUMEN

BACKGROUND: Telemedicine has been a popular tool to overcome the lack of access to healthcare facilities, primarily in underprivileged populations. We aimed to describe and assess the implementation of a tele-electrocardiography (ECG) program in primary care settings in Indonesia, and subsequently examine the short- and mid-term outcomes of patients who have received tele-ECG consultations. METHODS: ECG recordings from thirty primary care centers were transmitted to Makassar Cardiac Center, Indonesia from January to July 2017. We cross-sectionally measured the performance of this tele-ECG program, and prospectively sent a detailed questionnaire to general practitioners (GPs) at the primary care centers. We performed follow-up at 30 days and at the end of the study period to assess the patient outcomes. RESULTS: Of 505 recordings, all (100%) ECGs were qualified for analysis, and about half showed normal findings. The mean age of participants was 53.3 ± 13.6 years, and 40.2% were male. Most (373, 73.9%) of these primary care patients exhibited manifested CVD symptom with at least one risk factor. Male patients had more ischemic ECGs compared to women (p < 0.01), while older age (> 55 years) was associated with ischemic or arrhythmic ECGs (p < 0.05). Factors significantly associated with a normal ECG were younger age, female gender, lower blood pressure and heart rate, and no history of previous cardiovascular disease (CVD) or medication. More patients with an abnormal ECG had a history of hypertension, known diabetes, and were current smokers (p < 0.05). Of all tele-consultations, GPs reported 95% of satisfaction rate, and 296 (58.6%) used tele-ECG for an expert opinion. Over the total follow-up (14 ± 6.6 months), seven (1.4%) patients died and 96 (19.0%) were hospitalized for CVD. Of 88 patients for whom hospital admission was advised, 72 (81.8%) were immediately referred within 48 h following the tele-ECG consultation. CONCLUSIONS: Tele-ECG can be implemented in Indonesian primary care settings with limited resources and may assist GPs in immediate triage, resulting in a higher rate of early hospitalization for indicated patients.

RESUMEN

Aim: The objective of this study was to determine and compare the effectiveness of two methods of role playing and lecture on knowledge, attitude and performance of nursing' students in the context of pre-hospital triage. Design: This was a pre-test-posttest quasi-experimental study. Methods: A total of 66 nursing students (third year) were assigned to two groups, the control group (N = 23) and intervention group (N = 23). START pre-hospital triage was taught to two groups by using a lecture (control group) and role playing (intervention group) method. Immediately before the intervention and 4 weeks after the training, students' knowledge, attitude and practice in both groups were assessed through a questionnaire and a checklist. Data were analysed using SPSS software version 21. Results: The results showed that the mean scores of knowledge, attitude and performance increased after intervention in both groups (p < .05). The mean (SD) difference of total performance score from baseline to follow-up in the experimental group and the control group was 23.91 (13.83) and 7.00 (13.20), respectively (p < .001). While there was no significant difference between the mean (SD) difference of knowledge and attitude scores in the experimental group and the control group before and after the intervention (p > .05).

RESUMEN

BACKGROUND: Pre-hospital triage with ECG-transmission may reduce time to reperfusion in patients with ST-elevation acute myocardial infarction (STEMI). Less, however, is known on potential benefit of ECG-transmission triage in mountain areas, with complex orography. METHODS: Patients admitted for STEMI and primary coronary angioplasty (pPCI) in a mountain area served by a single cathlab and triaged with ECG-transmission were enrolled in the study and compared with controls: patients' demographics and time to coronary wire were recorded. RESULTS: Forty-seven consecutive patients were enrolled in the study: 23 patients following ECG transmission and 24 STEMI patients who presented directly to the Emergency Department. At multivariable regression analysis, pre-hospital ECG-transmission electrocardiogram was an independent predictor of shorter time-to-wire (beta -0.34, p < 0.05). In case of transport times >30 min, ECG-transmission triage achieved time-to-wire times 20% shorter. Excluding unreducible transport time, avoidable delay was reduced by 38% in the whole population, by 48% in case of peripheral areas (transport time > 30 min from cathlab) and elderly (>80 years) patients (p < 0.05 in all cases). CONCLUSIONS: Pre-hospital triage with ECG-transmission is associated with shorter ischemic time even in mountain areas with a complex orography profile. The benefit is greater in elderly patients and remote areas.

RESUMEN

Background Early triage is essential to improve outcomes in patients with suspected acute myocardial infarction (AMI). This study investigated whether cMyC (cardiac myosin-binding protein), a novel biomarker of myocardial necrosis, can aid early diagnosis of AMI and risk stratification. Methods and Results cMyC and high-sensitivity cardiac troponin T were retrospectively quantified in blood samples obtained by ambulance-based paramedics in a prospective, diagnostic cohort study. Patients with ongoing or prolonged periods of chest discomfort, acute dyspnoea in the absence of known pulmonary disease, or clinical suspicion of AMI were recruited. Discrimination power was evaluated by calculating the area under the receiver operating characteristics curve; diagnostic performance was assessed at predefined thresholds. Diagnostic nomograms were derived and validated using bootstrap resampling in logistic regression models. Seven hundred seventy-six patients with median age 68 [58;78] were recruited. AMI was the final adjudicated diagnosis in 22%. Median symptom to sampling time was 70 minutes. cMyC concentration in patients with AMI was significantly higher than with other diagnoses: 98 [43;855] versus 17 [9;42] ng/L. Discrimination power for AMI was better with cMyC than with high-sensitivity cardiac troponin T (area under the curve, 0.839 versus 0.813; P=0.005). At a previously published rule-out threshold (10 ng/L), cMyC reaches 100% sensitivity and negative predictive value in patients after 2 hours of symptoms. In logistic regression analysis, cMyC is superior to high-sensitivity cardiac troponin T and was used to derive diagnostic and prognostic nomograms to evaluate risk of AMI and death. Conclusions In patients undergoing blood draws very early after symptom onset, cMyC demonstrates improved diagnostic discrimination of AMI and could significantly improve the early triage of patients with suspected AMI.

RESUMEN

Background: Patients with acute ischemic stroke (AIS) and large vessel occlusion benefit from rapid access to mechanical thrombectomy in addition to intravenous thrombolysis. Prehospital triage algorithms to determine the optimal transport destination for AIS patients with unknown vessel status have so far only considered two alternatives: the nearest comprehensive (CSC) and the nearest primary stroke center (PSC). Objective: This study explores the importance of considering a larger number of PSCs during pre-hospital triage of AIS patients. Methods: Analysis was performed in random two-dimensional abstract geographic stroke care infrastructure environments and two models based on real-world geographic scenarios. Transport times to CSCs and PSCs were calculated to define sub-regions with specific triage properties. Possible transport destinations included the nearest CSC, the nearest PSC, and any of the remaining PSCs that are not closest to the scene, but transport to which would imply a shorter total time-to-CSC-via-PSC. Results: In abstract geographic environments, the median relative size of the sub-region where a triage decision is required ranged from 34 to 92%. The median relative size of the sub-region where more than two triage options need to be considered ranged from 0 to 56%. The achievable reduction in time-to-thrombectomy ("benefit") exceeded the increase in time-to-thrombolysis ("harm") by a factor of 2 in 30.5-37.0% of the sub-region where more than two triage options need to be considered. Results were confirmed in geographic environments based on real-world urban and rural stroke care infrastructures. Conclusion: Pre-hospital triage algorithms for AIS patients that only take into account the nearest CSC and the nearest PSC as transport destinations may be unable to identify the optimal transport destination for a significant proportion of patients.

RESUMEN

BACKGROUND: The first study of the FamouS Triage project investigates the feasibility of ruling out a myocardial infarction in pre-hospital chest pain patients without electrocardiographic ST-segment elevation by using the modified HEART score at the patient's home, incorporating only a single highly sensitive troponin T measurement. METHODS: A venous blood sample was drawn in the ambulance from 1127 consecutive chest pain patients for measurement of the pre-hospital highly sensitive troponin T levels, in order to establish a pre-hospital HEART score (i.e. the modified HEART score) and evaluate the possibility of triage at the patient's home. The primary endpoint was the occurrence of a major adverse cardiac event (MACE) i.e. acute myocardial infarction, percutaneous coronary intervention, coronary artery bypass grafting or death within 30 days after initial presentation. RESULTS: Two hundred and six patients (18%) developed a MACE during 30 days of follow-up. Thirty-six per cent of the patients ( n=403) had a low modified HEART score (0-3 points) and none of them developed a MACE during follow-up. Forty-four per cent of the patients ( n=494) had an intermediate modified HEART score (4-6 points) and 18% of them developed a MACE. Twenty per cent of the patients ( n=230) had a high modified HEART score (7-10 points) of which 52% developed a MACE during follow-up. CONCLUSION: It seems feasible to rule out a myocardial infarction at home in chest pain patients without ST-segment elevation by using the modified HEART score. TRIAL ID: NTR4205. Dutch Trial Register [ http://www.trialregister.nl ]: trial number 4205.

RESUMEN

As patient numbers continue to rise Emergency Department's (ED's) are struggling to not only control patient wait times but also to maintain the quality of patient care. Improving patient flow through the ED has been a priority for many years with techniques such as Lean Six-Sigma being implemented specifically to help alleviate the problem. The Institute for Healthcare Improvement recently stated that the best opportunities to improving patient flow relate to the front-end of the ED, namely triage. This contribution examines the use of Telehealth initiatives at the front-end of the ED, specifically tele-consultation, to reduce patient loading, provide timelier healthcare (with improved patient outcomes) and reduce costs.

RESUMEN

BACKGROUND: We sought to determine if our regional program for pre-hospital STEMI diagnosis and direct transfer for primary PCI (PPCI) was associated with shorter ischaemic times and improved survival compared with ED diagnosis. METHODS: STEMI diagnosis was made at the scene by pre-hospital ECG or in local EDs depending on patient presentation. Ambulance ECGs were transmitted to our ED for cath lab activation. Patient variables and outcomes at 12 months were recorded. RESULTS: We treated 782 consecutive patients with PPCI during January 2008-June 2013. Cath lab activation was initiated prior to hospital arrival (pre-hospital) in 24% of cases and by ED in 76% of cases. Median total ischaemic time was 154 min for pre-hospital and 211 minutes for ED patients (p<0.0001). Mortality at 12 months was 7.9% in the ED group compared with 3.7% in the pre-hospital group (p=0.036). On multivariate Cox regression analysis including baseline and procedural variables, pre-hospital activation remained an independent predictor of mortality (HR 0.45, 95% CI 0.20-1.0, p=0.03). CONCLUSIONS: Pre-hospital diagnosis of STEMI and direct transfer to the cath lab reduced total ischaemic time by 57 minutes and mortality by >50% following PPCI. Further efforts are needed to increase the proportion of STEMI patients treated using this strategy.

RESUMEN

Core temperature (T core) measurement is the only diagnostic tool to accurately assess the severity of hypothermia. International recommendations for management of accidental hypothermia encourage T core measurement for triage, treatment, and transport decisions, but they also recognize that lack of equipment may be a limiting factor, particularly in the field. The aim of this nonsystematic review is to highlight the importance of field measurement of T core and to provide practical guidance for clinicians on pre-hospital temperature measurement in accidental and therapeutic hypothermia. Clinicians should recognize the difference between alternative measurement locations and available thermometers, tailoring their decision to the purpose of the measurement (i.e., intermittent vs. continual measurement), and the impact on management decisions. The importance of T core measurement in therapeutic hypothermia protocols during early cooling and monitoring of target temperature is discussed.
