Emergency department outcome of elderly patients assisted by professional home services, the EPIGER study.

BACKGROUND: For the elderly population living at home, the implementation of professional services tends to mitigate the effect of loss of autonomy and increases their quality of life. While helping in avoiding social isolation, home services could also be associated to different healthcare pathways. For elderly patients, Emergency Departments (EDs) are the main entrance to hospital where previous loss of autonomy is associated to worst hospital outcomes. Part of elderly patients visiting EDs are still admitted to hospital for having difficulties coping at home without presenting any acute medical issue. There is a lack of data concerning elderly patients visiting EDs assisted by home services. Our aim was to compare among elderly patients visiting ED those assisted by professional home services to those who do not in terms of emergency resources' use and patients' outcome. METHODS: A multicenter, prospective cohort study was performed in 124 French EDs during a 24-h period on March 2016.Consecutive patients living at home aged ≥80 years were included. The primary objective was to assess the risk of mortality for patients assisted by professional home services vs. those who were not. Secondary objectives included admission rate and specific admission rate for "having difficulties coping at home". The primary endpoint was in-hospital mortality. Cox proportional-hazards regression model was used to test the association between professional home services and the primary endpoint. Multi variables logistic regressions were performed to assess secondary endpoints. RESULTS: One thousand one hundred sixty-eight patients were included, median age 86(83-89) years old,32% were assisted by professional home services. The overall in-hospital mortality rate was 7%. Assisted patients had more investigations performed. Home services were not associated with increased in-hospital mortality (HR = 1.34;95%CI [0.68-2.67]), nor with the admission rate (OR = 0.92;95%CI [0.65-1.30]). Assisted patients had a lower risk of being admitted for "having difficulties coping at home" (OR = 0.59;95%CI [0.38-0.92]). CONCLUSION: Professional home services which assist one-third of elderly patients visiting EDs, were not associated to lower in-hospital mortality or to an increased admission rate. Assisted patients were associated to a lower risk of being admitted for «having difficulties coping at home¼.Professional home services could result in avoiding some admissions and their corollary complications.

Prognostic value of prehospital quick sequential organ failure assessment score among patients with suspected infection.

OBJECTIVE: After the third international consensus on sepsis released its new definitions, the prognostic value of quick sequential organ failure assessment (qSOFA) score has been confirmed in the emergency department. However, its validity in the prehospital setting remains unknown. The objective of the study was to assess its accuracy for prehospital patients cared by emergency physician-staffed ambulances (services mobiles d'urgence et de réanimation SMUR). PATIENTS AND METHODS: This was a prospective observational multicenter cohort study (N = 6). All consecutive patients with prehospital clinical suspicion of infection by the emergency physician of the SMUR emergency medical service were included. Components of qSOFA were collected, and the patients were followed until hospital discharge. The primary end point was in-hospital mortality, censored at 28 days. Secondary end points included ICU admission longer than 72 h and a composite of 'death or ICU stay more than 72 h'. RESULTS: We screened 342 patients and included 332 in the analysis. Their mean age was 73 years, 159 (48%) were women, and the most common site of infection was respiratory (73% of cases). qSOFA was at least 2 in 133 (40%) patients. The overall in-hospital mortality was 27%: 41% in patients with qSOFA of at least 2 versus 18% for qSOFA less than 2 (absolute difference 23%; 95% confidence interval: 13-33%, P < 0.001). The overall discrimination for qSOFA was poor, with an area under the receiver operating characteristic curve of 0.69 (95% confidence interval: 0.62-0.74). CONCLUSION: In this large multicenter study, prehospital qSOFA presents a strong association with mortality in infected patient, though with poor prognostic performances in our severely ill sample.

Effect of Bag-Mask Ventilation vs Endotracheal Intubation During Cardiopulmonary Resuscitation on Neurological Outcome After Out-of-Hospital Cardiorespiratory Arrest: A Randomized Clinical Trial.

Importance: Bag-mask ventilation (BMV) is a less complex technique than endotracheal intubation (ETI) for airway management during the advanced cardiac life support phase of cardiopulmonary resuscitation of patients with out-of-hospital cardiorespiratory arrest. It has been reported as superior in terms of survival. Objectives: To assess noninferiority of BMV vs ETI for advanced airway management with regard to survival with favorable neurological function at day 28. Design, Settings, and Participants: Multicenter randomized clinical trial comparing BMV with ETI in 2043 patients with out-of-hospital cardiorespiratory arrest in France and Belgium. Enrollment occurred from March 9, 2015, to January 2, 2017, and follow-up ended January 26, 2017. Intervention: Participants were randomized to initial airway management with BMV (n = 1020) or ETI (n = 1023). Main Outcomes and Measures: The primary outcome was favorable neurological outcome at 28 days defined as cerebral performance category 1 or 2. A noninferiority margin of 1% was chosen. Secondary end points included rate of survival to hospital admission, rate of survival at day 28, rate of return of spontaneous circulation, and ETI and BMV difficulty or failure. Results: Among 2043 patients who were randomized (mean age, 64.7 years; 665 women [32%]), 2040 (99.8%) completed the trial. In the intention-to-treat population, favorable functional survival at day 28 was 44 of 1018 patients (4.3%) in the BMV group and 43 of 1022 patients (4.2%) in the ETI group (difference, 0.11% [1-sided 97.5% CI, -1.64% to infinity]; P for noninferiority = .11). Survival to hospital admission (294/1018 [28.9%] in the BMV group vs 333/1022 [32.6%] in the ETI group; difference, -3.7% [95% CI, -7.7% to 0.3%]) and global survival at day 28 (55/1018 [5.4%] in the BMV group vs 54/1022 [5.3%] in the ETI group; difference, 0.1% [95% CI, -1.8% to 2.1%]) were not significantly different. Complications included difficult airway management (186/1027 [18.1%] in the BMV group vs 134/996 [13.4%] in the ETI group; difference, 4.7% [95% CI, 1.5% to 7.9%]; P = .004), failure (69/1028 [6.7%] in the BMV group vs 21/996 [2.1%] in the ETI group; difference, 4.6% [95% CI, 2.8% to 6.4%]; P < .001), and regurgitation of gastric content (156/1027 [15.2%] in the BMV group vs 75/999 [7.5%] in the ETI group; difference, 7.7% [95% CI, 4.9% to 10.4%]; P < .001). Conclusions and Relevance: Among patients with out-of-hospital cardiorespiratory arrest, the use of BMV compared with ETI failed to demonstrate noninferiority or inferiority for survival with favorable 28-day neurological function, an inconclusive result. A determination of equivalence or superiority between these techniques requires further research. Trial Registration: clinicaltrials.gov Identifier: NCT02327026.

Management of chest pain in the French emergency healthcare system: the prospective observational EPIDOULTHO study.

OBJECTIVE: The aim of this paper was to describe the epidemiology, and diagnostic and therapeutic strategies that emergency physicians use to manage patients presenting with chest pain at all three levels of the French emergency medical system - that is, dispatch centres (SAMUs: the medical emergency system), which operate the mobile intensive care units (MICUs), and hospitals' emergency departments (EDs), with a focus on acute coronary syndrome (ACS). PATIENTS AND METHODS: All patients with chest pain who contacted a SAMU and/or were managed by a MICU and/or were admitted into an ED were included in a 1-day multicentre prospective study carried out in January 2013. Data on diagnostic and therapeutic management and disposition were collected. An in-hospital follow-up was performed. RESULTS: In total, 1339 patients were included: 537 from SAMU, 187 attended by a MICU and 615 in EDs. Diagnosing ACS was the main diagnostic strategy of the French emergency care system, diagnosed in 16% of SAMU patients, 25% of MICU patients and 10% of ED patients. Among patients calling the SAMU, 76 (14%) received only medical advice, 15 (8%) patients remained at home after being seen by a MICU and 454 (74%) were discharged from an ED. CONCLUSION: Management of chest pain at the three levels of the French medical emergency system is mainly oriented towards ruling out ACS. The strategy of diagnostic management is based on minimizing missed diagnoses of ACS.

Long-term prognosis after out-of-hospital resuscitation of cardiac arrest in trauma patients: prehospital trauma-associated cardiac arrest.

BACKGROUND: Although prehospital cardiac arrest (CA) remains associated with poor long-term outcome, recent studies show an improvement in the survival rate after prehospital trauma associated CA (TCA). However, data on the long-term neurological outcome of TCA, particularly from physician-staffed Emergency Medical Service (EMS), are scarce, and results reported have been inconsistent. The objective of this pilot study was to evaluate the long-term outcome of patients admitted to several trauma centres after a TCA. METHODS: This study is a retrospective database review of all patients from a multicentre prospective registry that experienced a TCA and had undergone successful cardiopulmonary resuscitation (CPR) prior their admission at the trauma centre. The primary end point was neurological outcome at 6 months among patients who survived to hospital discharge. RESULTS: 88 victims of TCA underwent successful CPR and were admitted to the hospital, 90% of whom were victims of blunt trauma. Of these 88 patients, 10 patients (11%; CI 95% 6% to 19%) survived to discharge: on discharge, 9 patients displayed a GCS of 15 and Cerebral Performance Categories (CPC) 1-2 and one patient had a GCS 7 and CPC of 3. Hypoxia was the most frequent cause of CA among survivors. 6-month follow-up was achieved for 9 patients of the 10 surviving patients. The 9 patients with a good outcome on hospital discharge had a CPC of 1 or 2 6 months post discharge. All returned to their premorbid family and social settings. CONCLUSIONS: Among patients admitted to hospital after successful CPR from TCA, hypoxia as the likely aetiology of arrest carried a more favourable prognosis. Most of the patients successfully resuscitated from TCA and surviving to hospital discharge had a good neurological outcome, suggesting that prehospital resuscitation may not be futile.

Tracheal intubation related complications in the prehospital setting.

BACKGROUND: Prehospital tracheal intubation (TI) is associated with morbidity and mortality, particularly in cases of difficult intubation. The goal of the present study was to describe factors associated with TI related complications in the prehospital setting. METHODS: This was a prospective cohort study including all patients intubated on scene in a prehospital emergency medical service over a 4 year period. TI related complications included oxygen desaturation, aspiration, vomiting, bronchospasm and/or laryngospasm, and mechanical complications (mainstem intubation, oesophageal intubation and airway lesion- that is, dental or laryngeal trauma caused by the laryngoscope). Difficult intubation was defined as >2 failed laryngoscopic attempts, or the need for any alternative TI method. A multivariate logistic regression was used to identify the risk factors for TI related complications. RESULTS: 1251 patients were included; 208 complications occurred in 165 patients (13.1%). Among the 208 complications, the most frequent were oesophageal intubation (n=69, 29.7%), desaturation (n=58, 25.0%) and mainstem intubation (n=37, 15.9%). In multivariate analysis, difficult intubation (OR=6.13, 3.93 to 9.54), Cormack and Lehane grades 3 and 4 (OR=2.23, 1.26 to 3.96 for Cormack and Lehane grade 3 and OR=2.61, 1.28 to 5.33 for Cormack and Lehane grade 4 compared with Cormack and Lehane grade 1) and a body mass index >30 kg/m(2) (OR=2.22, 1.38 to 3.56) were significantly associated with TI related complications. CONCLUSIONS: Despite specific guidelines, TI related complications are more frequent in the prehospital setting when intubation is deemed difficult, the Cormack and Lehane grade is greater than grade 1 and the patient is overweight. In such situations, particular attention is needed to avoid complications.

Evaluation of the performance of French physician-staffed emergency medical service in the triage of major trauma patients.

BACKGROUND: Proper prehospital triage of trauma patients is a cornerstone for the process of care of trauma patients. In France, emergency physicians perform this process according to a national triage algorithm called Vittel Triage Criteria (VTC), introduced in 2002 to help the triage decision-making process. The aim of this two-center study was to evaluate the performance of the triage process based on the VTC to identify major trauma patients in the Paris area. METHODS: This was a retrospective analysis of two cohorts. The first cohort consisted of all patients admitted between January 2011 and September 2012 in two trauma referral centers in the region of Paris (Ile de France) and allowed estimation of overtriage. Undertriage was assessed in a second cohort made up of all prehospital trauma interventions from one emergency medicine sector during the same period. Adequate triage was defined by a direct admission of patients with an Injury Severity Score (ISS) greater than 15 into one of the regional trauma centers, and undertriage was defined as an initial nonadmission to a trauma center. Overtriage was defined by an admission of patients with an ISS of 15 or lower to a trauma center. The performance of the VTC was evaluated according to a strict to-the-letter application of the VTC and termed as theoretical triage. Logistic regression was performed to identify VTC criteria able to predict major trauma. RESULTS: Among 998 admitted patients of the first cohort, 173 patients (17%) were excluded because they were not directly admitted in the first 24 hours. In the first cohort (n = 825), adequate triage was 58% and overtriage was 42%. In the second cohort (n = 190), adequate triage was 40%, overtriage was 60%, and undertriage was less than 1%. Theoretical triage generated a nonsignificantly lower overtriage and a higher undertriage compared with observed triage. The most powerful predictors of major trauma were paralysis (odds ratio [OR,] 0.09; 95% confidence interval [CI], 0.03-0.22), flail chest (OR, 0.1; 95% CI, 0.01-0.03), and Glasgow Coma Scale (GCS) score of less than 13 (OR, 0.28; 95% CI, 0.17-0.45), whereas global assessments of speed and mechanism alone were poor predictors (positive likelihood ratio, 0.92-1.4). CONCLUSION: In the Paris area, the French physician-based prehospital triage system for patients with suspicion of major trauma showed a high rate of overtriage and a low rate of undertriage. Criteria of global assessment of speed and mechanism alone were poor predictors of major trauma.

Nonurgent commercial air travel after nonhemorrhagic cerebrovascular accident.

Nonurgent commercial air travel in patients who have experienced a nonhemorrhagic cerebrovascular accident (CVA) may occur, particularly in the elderly traveling population. A recent CVA, particularly occurring during a person's travel, presents a significant challenge to the patient, companions, family, and health care team. Specific medical recommendation, based on accumulated scientific data and interpreted by medical experts, is needed so that travel health care professionals can appropriately guide the patient. Unfortunately, such recommendations are almost entirely lacking despite the relative frequency of CVA and air travel. This article reviews the existing recommendations with conclusions based on both these limited data and rationale conjecture.

Air travel of patients with abdominal aortic aneurysm: urgent air medical evacuation and nonurgent commercial air repatriation.

Abdominal aortic aneurysm (AAA) presents across a spectrum of severity. Although some resources suggest a theoretic risk for rupture related to air travel, this claim remains unproven. In fact, there are little data from which to make evidence-based recommendations. Air medical evacuation of a patient with either an AAA at risk of imminent rupture or status post recent rupture can be performed, assuming that local surgical care is not available and that transfer is taking the patient to a higher level of medical intervention. Furthermore, medical opinion suggests that patients with asymptomatic and/or surgically corrected AAA can safely travel by commercial aircraft for nonurgent reasons, assuming that other issues including postoperative needs are appropriately addressed. In this discussion, answers to the following issues are sought: flight safety for urgent evacuation and nonurgent repatriation scenarios, waiting time to fly nonurgently after AAA diagnosis, and the need for medical accompaniment.

Use of bispectral index to monitor the depth of sedation in mechanically ventilated patients in the prehospital setting.

BACKGROUND: Sedative drug administration is a challenging aspect of the management of mechanically ventilated patients in the out-of-hospital critical care medicine. We hypothesised that the bispectral index of the EEG (BIS) could be a helpful tool in evaluating the depth of sedation in this difficult environment. The main objective of the present study was to assess the agreement of BIS with the clinical scales in the out-of-hospital setting. METHODS: This prospective study included mechanically ventilated patients. BIS values were blindly recorded continuously. A Ramsay score was performed every 5 min. The main judgement criterion was the correlation between BIS values and the Ramsay score. RESULTS: 72 patients were included, mostly presenting with toxic coma (36%) or neurological coma (21%). The median (IQR) BIS value was 85 (84-86) when the Ramsay score was 3, 80 (76-84) when the Ramsay score was 4, 61 (55-80) when the Ramsay score was 5 and 45 (38-60) when the Ramsay score was 6. According to Receiver operating characteristic (ROC) curves, BIS was categorised into three classes (BIS<54 corresponding to Ramsay score 6, 54≤BIS<72 for Ramsay score 5 and BIS≥73 for Ramsay score ≤4). Based on these categories, the proportion of appropriate BIS values was 67% (217/323). The concordance correlation coefficient for repeated measurements was 0.54 (0.43-0.64). The agreement between BIS and the Ramsay score is moderate. CONCLUSIONS: Prehospital measured BIS values appear poorly correlated with clinical assessment of the depth of sedation. For this reason, the use of BIS to guide prehospital sedation cannot be recommended.

Commercial air travel after pneumothorax: a review of the literature.

Because of the physiological stresses of commercial air travel, the presence of a pneumothorax has long been felt to be an absolute contraindication to flight. Additionally, most medical societies recommend that patients wait at least 2 weeks after radiographic resolution of the pneumothorax before they attempt to travel in a nonurgent fashion via commercial air transport. This review sought to survey the current body of literature on this topic to determine if a medical consensus exists; furthermore, this review considered the scientific support, if any, supporting these recommendations. In this review, we found a paucity of data on the issue and noted only a handful of prospective and retrospective studies; thus, true evidence-based recommendations are difficult to develop at this time. We have made recommendations, when possible, addressing the nonurgent commercial air travel for the patient with a recent pneumothorax. However, more scientific research is necessary in order to reach an evidence-based conclusion on pneumothoraces and flying.

Commercial aircraft repatriation of patients with pneumothorax.

The transfer of patients with a pneumothorax via a commercial airline involves many medical, aeronautic, and regulatory considerations. In an attempt to further investigate these issues, we reviewed the medical records of 32 patient cases with a pneumothorax who were repatriated on commercial aircrafts. Sixteen patients were transferred with the thoracostomy tube in place and were escorted by medical personnel at an average of 5 days (interquartile range [IQR], 4-7 days) from diagnosis. Five patients without initial intercostal drainage (who either showed very limited air collection or underwent immediate surgical treatment) were all escorted by a physician at an average of 24 days (IQR, 18-25 days) of diagnosis. Eleven patients were transferred without medical escort aboard a commercial flight after removal of the chest tube at an average of 15 days (IQR, 9-17 days) of the diagnosis. This case review suggests that physicians recommend and follow markedly different management plans for the patient with a pneumothorax who is being transferred nonurgently by a commercial airliner. This differing practice management also is noted in the various existing specialty and industry guidelines, which are not evidence based; our review shows that poor agreement exists not only in these various guidelines but also among medical practitioners.

Multidrug-resistant bacteria among patients treated in foreign hospitals: management considerations during medical repatriation.

BACKGROUND: The repatriation of patients from foreign hospitals can foster the emergence and spread of multidrug-resistant bacteria (MRB). We aimed to evaluate the incidence of MRB in patients treated in foreign hospitals and repatriated by international inter-hospital air transport in order to better manage these patients and adjust our procedures. METHODS: The records from all consecutive aeromedical evacuations and overseas repatriations carried out by Mondial Assistance France between December 2010 and November 2011 were reviewed for this study. Only inter-hospital transfers with inpatient destination of an acute care unit were considered. Patients were allocated to one of two groups: those identified as MRB carriers at their arrival in France and those who were not identified as such (either negative for MRB or not tested). Data were compared between the two groups. RESULTS: Analysis was performed on 223 patients: 16 patients (7%) were identified as MRB carriers. Compared with confirmed non-MRB patients, MRB carriers came more frequently from a high-risk unit (88% vs 59%, p = 0.05) and had a longer foreign hospital stay [13 (3-20) vs 8 (6-14) d, p = 0.01]. CONCLUSIONS: The occurrence of MRB among patients repatriated from foreign hospitals is noted in a significant minority of such individuals transferred back to their home country. The typical MRB patient was admitted to a high-risk unit in a foreign hospital prior to repatriation with longer foreign hospital admissions. The prospective identification of these patients prior to transport is difficult. While these factors are associated with MRB presence, their absence does not rule out highly resistant bacterial colonization. A systematic review of this important medical issue is warranted with the development of guidelines.

Response time evaluation for emergency medical service as a part of its performance.

The study aimed to evaluate the response time (RT) of a French physician-staffed emergency medical service unit in both first-line and second-line service zones a part of its performance and how best to integrate it into its geographical specificity and showed acceptable RTs (mostly <10 min). Interestingly, because of the particular location next to other districts, RTs are in the same range for some municipalities that are adjacent to the first-line and area. In a new system in which catching areas would not only be based on administrative criteria anymore but also on performance evaluation, RTs for emergency medical service might be optimised.
