A retrospective comparison of mechanical cardio-pulmonary ventilation and manual bag valve ventilation in non-traumatic out-of-hospital cardiac arrests: A study from the Belgian cardiac arrest registry

BACKGROUND

The optimal ventilation modalities to manage out-of-hospital cardiac arrest (OHCA) remain debated. A specific pressure mode called cardio-pulmonary ventilation (CPV) may be used instead of manual bag ventilation (MBV). We sought to analyse the association between mechanical CPV and return of spontaneous circulation (ROSC) in non-traumatic OHCA.

METHODS

MBV and CPV were retrospectively identified in patients with non-traumatic OHCA from the Belgian Cardiac Arrest Registry. We used a two-level mixed-effects multivariable logistic regression analysis to determine the association between the ventilation modalities and outcomes. The primary and secondary study criteria were ROSC and survival with a Cerebral Performance Category (CPC) score of 1 or 2 at 30 days. Age, sex, initial rhythm, no-flow duration, low-flow duration, OHCA location, use of a mechanical chest compression device and Rankin status before arrest were used as covariables.

RESULTS

Between January 2017 and December 2021, 2566 patients with OHCA who fulfilled the inclusion criteria were included. 298 (11.6%) patients were mechanically ventilated with CPV whereas 2268 were manually ventilated. The use of CPV was associated with greater probability of ROSC both in the unadjusted (odds ratio: 1.28, 95% confidence interval [CI]: 1.01-1.63; p = 0.043) and adjusted analyses (adjusted odds ratio [aOR]: 2.16, 95%CI 1.37-3.41; p = 0.001) but not with a lower CPC score (aOR: 1.44, 95%CI 0.72-2.89; p = 0.31).

CONCLUSIONS

Compared with MBV, CPV was associated with an increased risk of ROSC but not with improved an CPC score in patients with OHCA. Prospective randomised trials are needed to challenge these results.

Perceived Hospital Preparedness Is Negatively Associated With Pandemic-Induced Psychological Vulnerability in Primary Care Employees: A Multicentre Cross-Sectional Observational Study

OBJECTIVE

The COVID-19 pandemic had a profound negative impact on the psychological wellbeing of healthcare providers (HPs), but little is known about the factors that positively predict mental health of primary care staff during these dire situations.

METHODS

We conducted an online questionnaire survey among 702 emergency department workers across 10 hospitals in Switzerland and Belgium following the first COVID-19 wave in 2020, to explore their psychological vulnerability, perceived concerns, self-reported impact and level of pandemic workplace preparedness. Participants included physicians, nurses, psychologists and nondirect care employees (administrative staff). We tested for predictors of psychological vulnerability through both an exploratory cross-correlation with rigorous correction for multiple comparisons and model-based path modelling.

RESULTS

Findings showed that the self-reported impact of COVID-19 at work, concerns about contracting COVID-19 at work, and a lack of personal protective equipment were strong positive predictors of Depression, Anxiety, and Stress, and low Resilience. Instead, knowledge of the degree of preparedness of the hospital/department, especially in the presence of a predetermined contingency plan for an epidemic and training sessions about protective measures, showed the opposite effect, and were associated with lower psychological vulnerability. All effects were confirmed after accounting for confounding factors related to gender, age, geographical location and the role played by HPs in the hospital/department.

CONCLUSIONS

Difficult working conditions during the pandemic had a major impact on the psychological wellbeing of emergency department HPs, but this effect might have been lessened if they had been informed about adequate measures for minimizing the risk of exposure.

Severe vitamin D deficiency in patients admitted to the emergency department with severe sepsis is associated with an increased 90-day mortality

BACKGROUND

The role of vitamin D in the response to infection has been increasingly acknowledged. However, the influence of severe vitamin D deficiency on the outcome of patients admitted for severe sepsis is unknown. Hence, this study aimed to investigate the association between severe vitamin D deficiency and sepsis-related outcomes in patients presenting to the ED.

METHODS

This single centre prospective study included patients presenting to the ED with severe sepsis from April 2014 until December 2017. 25-Hydroxy vitamin D (25(OH)D) was measured in a blood sample drawn within 24 hours of admission to the ED, and severe vitamin D deficiency was defined as 25(OH)D <12 ng/mL. 90-day mortality was compared between patients with and without severe vitamin D deficiency by a multivariable analysis adjusting for confounders and according to a Kaplan-Meier survival analysis.

RESULTS

263 patients were initially screened and 164 patients with severe sepsis were included in this study, 18% of whom had septic shock. Severe vitamin D deficiency was present in 46% of patients. The overall 90-day mortality rate was 26.2% and the median length of stay was 14 days. In a logistic regression accounting for sepsis severity and age-adjusted comorbidities, severe vitamin D deficiency was associated with increased mortality (OR=2.69 (95% CI 1.03 to 7.00), p=0.043), and lower chances of hospital discharge (sub-HR=0.66 (95% CI 0.44 to 0.98)). In the subgroup of patients admitted to the intensive care unit, severe vitamin D deficiency was associated with an increased 28-day adjusted mortality (HR=3.06 (95% CI 1.05 to 8.94), p=0.04) and lower chances of discharge (sub-HR=0.51 (95% CI 0.32 to 0.81)).

CONCLUSIONS

Severe vitamin D deficiency at ED admission is associated with higher mortality and longer hospital stay in patients with severe sepsis.

Impact of treatment delays on outcome of acute testicular torsion: a 15-year retrospective study

INTRODUCTION

Preservation of the testicle is directly associated with the duration of torsion. The aim in this retrospective study was to identify factors that influence pre-and in-hospital times and measure the extent to which these times affect testicle survival.

PATIENTS AND METHODS

A retrospective review of 116 patients who underwent exploration for testicular torsion between 2000 and 2015. Patients were divided into orchiectomy and salvaged testicle groups. Times in patient management and clinical features were compared with Mann-Whitney, chi-squared, and Fisher exact tests. Multivariate logistical regression was used to identify independent factors associated with orchiectomy.

RESULTS

The median prehospital time of 48 h (15.4-138 h) in the orchiectomy group was longer than the 2.4 h (1.6 h-5.2h) in the salvaged group. Patients examined by a general practitioner (GP) prior to presenting at hospital had a median prehospital time of 48 h, compared to 3 h for patients not examined before presentation at hospital. In-hospital times between admission and operation room, as well as times between ultrasonography and operation room, were also longer in the orchiectomy group. Previous GP consultation (OR = 27.26, 95% CI 2.32-320.59, p = .009), prehospital time (OR = 1.04, 95% CI 1.01-1.07, p = .003) and nausea (OR = 9.25, 95% IC 1.33-64.52, p = .025) were independent predictive factors associated with orchiectomy.

CONCLUSION

Prehospital time was a determining factor in orchiectomy. For each extra hour of prehospital delay, the risk of orchiectomy increased by 4%. The rate of orchiectomy was higher among patients who first consulted a GP.

The Automated External Defibrillator: Heterogeneity of Legislation, Mapping and Use across Europe. New Insights from the ENSURE Study

INTRODUCTION

The rapid use of an automated external defibrillator (AED) is crucial for increased survival after an out-of-hospital cardiac arrest (OHCA). Many factors could play a role in limiting the chance of an AED use. We aimed to verify the situation regarding AED legislation, the AED mapping system and first responders (FRs) equipped with an AED across European countries.

METHODS

We performed a survey across Europe entitled "European Study about AED Use by Lay Rescuers" (ENSURE), asking the national coordinators of the European Registry of Cardiac Arrest (EuReCa) program to complete it.

RESULTS

Nineteen European countries replied to the survey request for a population covering 128,297,955 inhabitants. The results revealed that every citizen can use an AED in 15 countries whereas a training certificate was required in three countries. In one country, only EMS personnel were allowed to use an AED. An AED mapping system and FRs equipped with an AED were available in only 11 countries. The AED use rate was 12-59% where AED mapping and FR systems were implemented, which was considerably higher than in other countries (0-7.9%), reflecting the difference in OHCA survival.

CONCLUSIONS

Our survey highlighted a heterogeneity in AED legislation, AED mapping systems and AED use in Europe, which was reflected in different AED use and survival.

Contribution of the FilmArray Respiratory Panel in the management of adult and pediatric patients attending the emergency room during 2015-2016 influenza epidemics: An interventional study

AIM

To evaluate the contribution of a multiplex PCR for respiratory viruses on antibiotic and antiviral prescription, ancillary test prescription, admission and length of stay of patients.

METHODS

Two hundred ninety-one adult and pediatric patients visiting the emergency department during the 2015-2016 influenza epidemic were prospectively included and immediately tested 24/7 using the FilmArray Respiratory Panel. The results were communicated to the practitioner in charge as soon as they became available. Clinical and biological data were gathered and analyzed.

FINDINGS

Results from the FilmArray Respiratory Panel do not appear to impact admission or antibiotic prescription, with the exception of a lower admission rate for children who tested positive for influenza B. Parameters that account for the clinical decisions evaluated are CRP level, white blood cell count, suspected or proven bacterial infection and, for adult patients only, signs of respiratory distress. Length of stay is also not significantly different between patients with a positive and a negative result. A rapid influenza test result permits a more appropriate prescription of oseltamivir.

Does endotracheal intubation increases chest compression fraction in out of hospital cardiac arrest: A substudy of the CAAM trial

BACKGROUND

Optimal out of hospital cardiac arrest (OHCA) airway management strategies remain unclear. We compared chest compression fraction (CCF) between patients receiving endotracheal intubation (ETI) versus bag mask ventilation (BMV).

METHODS

We studied adult OHCA enrolled from our center in the CAAM trial. Primary exposures were ETI or BMV. Primary outcome was whole intervention CCF, adjusted for Utstein confounders. Secondary outcomes were per cycle CCF, no flow time associated (NFT) with ventilation, rhythms checks and mechanical chest compression device placement.

RESULTS

Of 2040 OHCA enrolled in the CAAM trial we analyzed 112 cases recruited by our center. Unadjusted CCF was 0.89 for ETI and 0.88 for BMV (p = 0.19). Compared with BMV, ETI achieved lower NFT associated with ventilations (32 vs 127 s; p < 0.001). ETI cases experienced higher NFT associated with rhythm checks (69.5 vs 42.5 s p = 0.02) and with mechanical chest compression placement (29 vs 20 s; p = 0.04). CCF was higher during the first cycle in BMV than in ETI patients (0.81 vs 0.74; p = 0.02). After correction for confounders we observed no difference in global intervention CCF between the ETI and BMV (ΔCCF [ETI-BMV] 0.301; [95%CI: -1.9 to 2.51]; p = 0.79).

CONCLUSION

In our substudy whole intervention CCF among OHCA was not modified by ETI compared to BMV. In the ETI group we observed lower NFT associated with ventilations and higher NFT associated with mechanical chest compression devices placement. CCF was lower in the ETI group during the first cycle.

Prospective evaluation of diagnostic tools for respiratory viruses in children and adults

•

Molecular techniques have considerably improved sensitivity of viral diagnosis.

•

Interpretation of results can be delicate as DNA or RNA traces can be detected.

•

Their use is hindered by their cost and the difficulty to absorb high workloads.

•

Their impact in management of patients still has to be demonstrated.

•

Tertiary care hospitals should provide a testing algorithm to suit each case.

Aim

To compare the performances of molecular and non-molecular tests to diagnose respiratory viral infections and to evaluate the pros and contras of each technique.

Methods

Two hundred ninety-nine respiratory samples were prospectively explored using multiplex molecular techniques (FilmArray Respiratory Panel, Clart Pneumovir), immunological techniques (direct fluorescent assay, lateral flow chromatography) and cell cultures.

Findings

Molecular techniques permitted the recovery of up to 50% more respiratory pathogens in comparison to non-molecular methods. FilmArray detected at least 30% more pathogens than Clart Pneumovir which could be explained by the differences in their technical designs. The turnaround time under 2 hours for the FilmArray permitted delivery of results when patients were still in the emergency room.

Can We Define Termination Of Resuscitation Criteria In Out-Of-Hospital Hanging?

OBJECTIVE

Survival rate of cardiac arrest due to hanging (H-CA) victims is low. Hence, this leads to the question of the utility of resuscitation in these patients. The objective was to investigate whether there are predictive criteria for survival with a good neurological outcome or predictive criteria for non-survival or survival with a poor neurological outcome enabling us to define the termination of resuscitation rules in these patients.

METHODS

Between July 1, 2011 and January 1, 2016, we included 1,689 out-of-hospital cardiac arrests due to hanging. We compared the characteristics of survivors with a good neurological outcome at day 30 with the others.

RESULTS

The study population was mainly composed of males with a median age of 48 [37-60]. The overall survival was 2.1%, among which 48.6% had a good neurological outcome. Survivors benefited more often from immediate basic life support than the rest of the subjects, which was corroborated by the shorter no-flow durations. We did not record any difference in terms of advanced cardiac life support initiation frequency and technique between survivors with a good neurological outcome and the rest. Nevertheless, ACLS duration was longer in survivors with a good neurological outcome than in others.

CONCLUSIONS

Basic life support (BLS) was the decisive criterion for 15/17 survivors. However, a detailed analysis showed 2 survivors presenting no BLS before the arrival of mobile medical teams and non-shockable rhythms who survived at day 30 with a good neurological outcome. These results lead us to consider that mobile medical team intervention and ACLS attempt are not futile, and the benefit justifies the cost. Thus, we cannot define any rule for the termination of resuscitation.

Traumatic cardiac arrest is associated with lower survival rate vs. medical cardiac arrest - Results from the French national registry

INTRODUCTION

The survival from traumatic vs. medical out-of-hospital cardiac arrest (OHCA) are not yet well described. The objective of this study was to compare survival to hospital discharge and 30-day survival of non-matched and matched traumatic and medical OHCA cohorts.

MATERIAL & METHODS

National case-control, multicentre study based on the French national cardiac arrest registry. Following descriptive analysis, we compared survival rates of traumatic and medical cardiac arrest patients after propensity score matching.

RESULTS

Compared with medical OHCA (n = 40,878) trauma victims (n = 3209) were younger, more likely to be male and away from home at the time and less likely to be resuscitated. At hospital admission and at 30 days their survival odds were lower (OR: respectively 0.456 [0.353;0.558] and 0.240 [0.186;0.329]). After adjustment the survival odds for traumatic OHCA were 2.4 times lower at admission (OR: 0.416 [0.359;0.482]) and 6 times lower at day 30 (OR: 0.168 [0.117;0.241]).

CONCLUSIONS

The survival rates for traumatic OHCA were lower than for medical OHCA, with wider difference in matched vs. non-matched cohorts. Although the probability of survival is lower for trauma victims, the efforts are not futile and pre-hospital resuscitation efforts seem worthwhile.

[Bleeding induced by Selective Serotonine Reuptake inhibitors (SSRI). Case report and review of literature]

Selective serotonin re-uptake inhibitors are widely prescribed on a daily basis due to their recognized efficiency and their few side effects as opposed to tricyclic antidepressants. The iatrogenic effect mainly causes benign hemorrhagic episodes however some cases could get serious. The Belgian centre of pharmacotherapeutical information warns prescribing physicians regarding the use of SSRIs. The existing risk of cutaneo-mucosal bleeding or other forms of hemorrhage due to SSRIs has been identified in the early 90s based on reported cases. Since then, cohort epidemiology studies or case studies have shown a correlation between the SSRIs intake and bleeding, linked to inhibition of the serotonin re-uptake (5HT). We report 2 clinical cases of patients who presented hemorrhages. One has been taking sertraline and the other fluoxetine. Through this literature review, we aim at discussing the impact of the different physiopathologic mechanisms.

Application of the Canadian C-Spine rule and nexus low criteria and results of cervical spine radiography in emergency condition

Introduction

The Canadian C Spine Rule (CCR) and the National Emergency X-Radiography Utilization Study (Nexus) low criteria are well accepted as guide to help physician in case of cervical blunt trauma.

Methods

We aimed to evaluate retrospectively the application of these recommendations in our emergency department. Secondly we analyzed the quality of cervical spine radiography (CSR) in an emergency setting.

Results

281 patients with cervical blunt trauma were analyzed retrospectively. The CCR and the NEXUS rules were respected in 91.2% and 96.8% of cases respectively. No lesions were found in 96.4% of patient. A lesion was present in 1.1% of patient and suspected in 2.5% of patient. The quality of CSR was adequate in only 37.7% of patient. The poor quality of CSR was due either to the lack of C7 vertebrae visualization in 64.6% or other lower vertebrae in 28%. Other causes included the absence of open mouth view (8%), the absence C1 vertebrae visualization (3.4%), artifact in 2.3% and the absence of lateral view in 0.6% of patient.

Conclusion

CCR and NEXUS are widely used in our emergency department. The high rate of inadequate CSR reinforces the debate about it’s utility in emergency condition.

[About a cresol intoxication]

Cresols are phenol derivatives commonly used as surface disinfectants. Ingestion may cause local mucocutaneous damage and extensive systemic toxicity : central nervous, cardiovascular, hematological, hepatic, renal and pulmonary. We describe the case of a 33-year-old woman who swallowed, without suicidal intent, 50 to 70 cm3 of a 50% cresol solution. Coma occurred within 5 minutes of ingestion, she presented a bradypnea with desaturation, and the SMUR team performed on-site an orotracheal intubation. On arrival at the hospital, the patient had typical caustic lesions around her mouth. Immediate management consisted of ventilatory support, instillation of activated charcoal by nasogastric tube, empirical intravenous methylene blue and effective vascular filling. Within one hour of admission, she developed hypotension, ventricular arrhythmias, and acute renal failure. Toxic hepatitis occurred within 24 hours. The 24-hour gastroscopy showed erosive esophagitis and erythematous gastropathy and duodenopathy. No urine or blood dosage can be performed. The patient left the hospital on the fifth day and her liver function normalized after one month. The treatment of phenol poisoning consists primarily of rapid decontamination and the support of vital functions. Diagnostic assays are not available routinely and anamnesis, as well as some semiological cardinal points, is essential.

Development of an online, universal, Utstein registry-based, care practice report card to improve out-of-hospital resuscitation practices

RATIONALE, AIMS AND OBJECTIVES

Care quality is a primary concern in health field. In France, the care practice report card (CPRC) is compulsory for practitioners. It is the first step towards the culture of excellence. In this context, practitioners have to assess and improve their practices. Competent authorities define registries as reliable sources for CPRC. The first aim of this work is to describe how we designed and built a universally transposable CPRC model based on an Utstein-style cardiac arrest registry. The second aim is to measure the adherence of practitioners to this approach and to show how such a tool can be used in real situation.

METHODS

Our report card is adapted from in-hospital CA care quality and safety indicators. We built a 2-section grid. The first part described the quality and completeness of the analysed data. The second part distinguished medical and traumatic CA and assesses care practices. We analysed the practitioners' adherence thanks to a satisfaction survey. Finally, we presented a CPRC case study.

RESULTS

This tool was tested in 92 centres gathering 8433 patients. The satisfaction survey showed that this CPRC was well accepted by emergency professionals. We presented an implementation example of this tool in a centre in real-life situation.

CONCLUSIONS

We designed and implemented a fully automated CPRC tool routinely usable for Utstein-style CA registries. This CPRC is easily transferable in all other Utstein CA registries. The debriefing report source codes are freely distributed upon request. This tool enables the care assessment and improvement.

Hypoxemia after pneumothorax exsufflation: a case report

We describe a 36-year-old patient who was admitted to the emergency ward for acute dyspnea due to a spontaneous pneumothorax. He was successfully drained but shortly after presented a severe hypoxemia due to pulmonary oedema secondary to pulmonary re-expansion. The physiopathology behind this complication is still unknown. We will try to describe this complication and its predictive factors.

Adherence to HIV post-exposure prophylaxis: A multivariate regression analysis of a 5 years prospective cohort

BACKGROUND

Non-occupational post-exposure prophylaxis (nPEP) is a recommended public health intervention after a sexual or percutaneous exposure to human immunodeficiency virus (HIV).

METHODS

We conducted a prospective observational study recording consultations for nPEP at a reference HIV center in Brussels, Belgium from January 2011 to December 2015. We recorded attendance to follow-up, reported completion of nPEP and pharmacy records to measure adherence. Multivariate logistic regressions were performed to identify independent risk factors for adherence to nPEP and attendance to first follow-up visit at the STI clinic.

FINDINGS

Among 1881 patients receiving nPEP, 66.4% had a documented completion of a 28-day course of nPEP and 87.3% attended their first follow-up clinic visit. MSM (OR, 1.40; 95%CI, 1.04-1.90), being a native Belgian (OR, 1.50; 95%CI, 1.18-1.90), older age (OR, 1.02; 95%CI, 1.01-1.04), being a sexual assault survivor (OR, 0.59; 95%CI, 0.38-0.91), having had a previous nPEP treatment (OR, 1.44; 95%CI, 1.02-2.02), consultation during daytime (OR, 1.35; 95%CI, 1.07-1.70) and benefitting from a health insurance (OR, 2.11; 95%CI, 1.58-2.89) were significant independent predictors for adherence to nPEP. Patients whose initial treatment was AZT/3TC/IDV/r had similar adherence than patients on d4T/3TC/LPV/r (OR, 0.898; 95%CI, 0.68-1.20).

INTERPRETATION

Multiple independent risk factors for nPEP retention into care and adherence are present at treatment initiation and might be targeted by tailored interventions. Sexual assault victims are overexposed to deleterious consequences of the lack of health insurance on compliance.

Adrenaline in anaphylaxis treatment and self-administration: experience from an inner city emergency department

BACKGROUND

Anaphylaxis is a life-threatening emergency of which reliable epidemiological data are lacking. This study aimed to analyze how quickly patients presenting with anaphylaxis were treated in emergency and whether treatment followed the European Academy of Allergy and Clinical Immunology (EAACI) guidelines.

METHODS

Patient data were collected between April 2009 and April 2013. Emergency doctors completed a questionnaire for adult patients presenting at the emergency department (ED) of the St. Pierre hospital in Brussels with anaphylaxis. Inclusion criteria were based on the Sampson criteria of anaphylaxis. Data were analyzed using a Microsoft Excel database.

RESULTS

About 0.04% (100/230878) of all emergency visits in adults presented with anaphylaxis. 64% of patients received their first medical help later than 30 min after symptom onset. 67% of patients received adrenaline, 85% oral antihistamines, and 89% received IV glucocorticosteroids. 46/100 patients were discharged directly from the ED, of which 87% received further medical prescriptions for self-administration: 67% corticosteroids, 83% antihistamines, and 9% intramuscular adrenaline. 74% were instructed to consult an allergologist for adequate diagnosis. 54/100 patients were hospitalized.

CONCLUSION

The majority of patients were treated according to the EAACI guidelines for management of anaphylaxis, but only a minority received the recommended adrenaline auto-injector for self-administration at discharge. Because the majority of patients received medical help later than 30 min after symptom onset, adrenaline auto-injector prescription is a necessity. The low rate of doctors prescribing adrenaline auto-injectors in the ED setting underlines the need to train doctors of various backgrounds in prevention and treatment of anaphylaxis and the close collaboration with allergologists.

[Acute colonic diverticulitis : outcome according to general practice management prior to referral and criteria predictive of complications. A 10-year experience in a University Hospital]

INTRODUCTION

Ambulatory treatment of acute uncomplicated diverticulitis has been shown to be safe and effective by several recent studies. The aim of our study was to analyze the outcome of general practice management concerning the complications, the treatment modalities and the hospitalization duration during the first episode of acute diverticulitis.

MATERIEL AND METHODS

A total of 176 medical files of patient presenting between January 2000 and December 2010 at the emergency department with a first episode of acute diverticulitis confirmed by an abdominal CT scan were analyzed. Among the 160 patients fulfilling the inclusion criteria, 50 were referred by a general practitioner (GP). Data concerning admission modalities, clinical status, paraclinic investigations, complications, treatment and length of hospital stay were reviewed.

RESULTS

The patients referred by the GP were significantly older (p ⟨ 0.001) and were hospitalized significantly longer (p = 0.034) than the patients consulting directly the emergency department. There was a significant correlation between the 2 variables (R = 0.406). Complications and treatment modalities did not differ between the two groups. Complicated diverticulitis was associated with rebound (p = 0.049), tenderness (p = 0.005) and a time interval between initial symptoms onset and admission to the emergency department superior to 4 days (p = 0.027).

CONCLUSIONS

Ambulatory management of acute diverticulitis by the GP does not affect the outcome of the patients after their hospital admission in term of complications and treatment modalities. Ambulatory treatment of acute diverticulitis is safe but hospitalization is indicated in case of poor clinical tolerance, presence of rebound, tenderness and duration of symptoms for more than 4 days.

[Evaluations by hospital-ward physicians of patient care management quality for patients hospitalized after an emergency department admission]

BACKGROUND

patient management in the acute and sub-acute setting of an Emergency Department is challenging. An assessment of the quality of provided care enables an evaluation of failings. It contributes to the identification of areas for improvement.

OBJECTIVES

to obtain an analysis, by hospital-ward physicians, of adult patient care management quality, as well as of the correctness of diagnosis made during emergency admissions. To evaluate the consequences of inadequate patient care management on morbidity, mortality and cost and duration of hospitalization.

METHODS

prospective data analysis obtained between the 1/12/2009 and the 21/12/2009 from physicians using a questionnaire on adult-patient emergency admissions and subsequent hospitalization.

RESULTS

questionnaires were completed for 332 patients. Inadequate management of patient care were reported for 73/332 (22 %) cases. Incorrect diagnoses were reported for 20/332 (6 %) cases. 35 cases of inadequate care management (10.5 % overall) were associated with morbidity (34 cases) or mortality (1 case), including 4 cases (1.2 % ) that required emergency intensive-care or surgical interventions.

CONCLUSION

this quality study analyzed the percentage of patient management cases and incorrect diagnoses in the emergency department. The data for serious outcome and wrong diagnosis are comparable with current literature. To improve performance, we consider the process for establishing a diagnosis and therapeutic care.

[Genesis of specific multisite Medical Intervention Plans in the Brussels Capital Region]

After the november 19th 2015 Paris terrorist attacks, there was a clear need to update the Medical Intervention Plans (MIP) for Mass Casualty Events (MCE) in the Brussels Capital Region (BCR), because they only offered a response to single-site MCE in a peace-time context. We compared the organisation and the resources of the BCR and cities like Paris and Lille, we discussed with our french colleagues and formed a Multisite Attack Task-force that produced a specific multisite MIP, which had to be put to use only a few days after its creation.

[Pseudotumor cerebri due to taking minocycline]

The cerebral pseudotumor (PTC) is defined by the increase in cerebrospinal fluid (CSF) pressure, a normal composition of the latter in the absence of identified intracranial structural abnormalities, in particular by neuroimaging. The pathophysiology of PTC is poorly understood although its diagnostic criteria are well established. Drugs such as minocycline, tetracycline and doxycycline have been repeatedly implicated as a causative factor in PTC. The prognosis of PTC related to minocycline, reported in the literature is quite variable. Some authors suggest a benign condition with spontaneous healing by stopping the antibiotic, while others report permanent loss of vision. A 12-year-old girl is admitted to the emergency room for progressively progressive pulsatile temporal headaches associated with diplopia. The patient reported the use of minocycline 50 mg / d for five months, prescribed by her attending physician as part of an acne treatment. PTC will be demonstrated by severe papillary edema and cerebral NMR will demonstrate an enlargement of the subarachnoid space around the optic nerves. After three lumbar punctures, the condition of the patient stabilized and there was a marked improvement in headache despite the persistence of bilateral papillary edema. This work describes a clinical case of PTC induced by the use of minocycline and reviews the physiopathology, the diagnosis and the management of this one.

Cannabis body packing: a case report

Drug traffic is a major concern worldwide. We report a case of a 27-year old male who presented with a diffuse abdominal plain to the emergency department. Abdominal X-ray demonstrated multiple foreign bodies along the intestinal tract, which were found to be cannabis packets. The patient was treated conservatively with a good result.

[Legionnaires' disease complicated by rhabdomyolysis and acute renal failure: about a case]

La légionellose est une maladie respiratoire bactérienne due à un germe gram négatif dont la présentation clinique peut être bénigne se limitant à un syndrome grippal ou plus sévère se caractérisant par une pneumonie pouvant se compliquer d'atteinte multisystémique pouvant conduire au décès. Nous rapportons le cas d'un patient de 48 ans ayant présenté une rhabdomyolyse compliquée d'une insuffisance rénale aigue au décours d'une pneumonie à Legionella pneumophila. Nous revoyons la physiopathologie et le traitement de cette complication rare de la légionellose.

Prescription of Non-Occupational Post-Exposure HIV Prophylaxis by Emergency Physicians: An Analysis on Accuracy of Prescription and Compliance

We conducted a retrospective analysis of data from a prospective nPEP (non-Occupational Post Exposure Prophylaxis) registry based on patients consulting at one academic Emergency department located in Brussels, Belgium. We review here 1,357 cases consulting from January 2011 to December 2013.The objective of the study is to determine whether emergency physicians prescribe nPEP according to national guideline with support from IDS (infectious disease specialists). As this intervention has a high cost we wanted to verify correct allocation of treatment to high risk patients. Moreover we wanted to determine whether compliance to nPEP when prescribed by an Emergency Physician was different from literature reports. Finally we wanted to describe the population consulting for nPEP at our center. Emergency physicians prescribed nPEP more frequently in high risk exposures (98.6%) compared to intermediate risk exposures (53.2%); adequately allocating resources from a public health perspective. Appropriateness of prescription when evaluated according to nPEP Belgian guidelines was 98.8%.Compliance with nPEP prescribed by Emergency physicians was 60% in our study. Compliance was the highest in MSM (Men who have Sex with Men) while sexual assault victims showed the lowest compliance. Altogether this study suggests that Emergency physicians can safely and adequately prescribe nPEP when supported by a comprehensive guideline. Recognizing intrinsic differences within heterogeneous populations consulting for nPEP may improve compliance to this high-cost public health intervention.

Anaphylaxis in an urban Belgian emergency department: epidemiology and aetiology

OBJECTIVES

Anaphylaxis is an emergency condition of which reliable epidemiological data are lacking. This study focusses on epidemiology and aetiology of anaphylactic reactions in an urban Belgian emergency department (ED).

METHODS

Patient data were collected from 04/2009 to 04/2013.During this period, emergency doctors completed a questionnaire for adult patients (>15 years) with anaphylaxis presenting at the ED. Inclusion criteria were based on the Sampson criteria of anaphylaxis. Data were analysed using a Microsoft Excel database.

RESULTS

Anaphylaxis accounted for 0.04% of all emergency visits in this 4-year period. In both women and men, dyspnoea and urticaria were noted most frequently. 51.7% of cases were possibly elicited by foods, 46.1% by drugs and 3.4% by hymenoptera stings. Women more often reported allergic diseases in their personal history. 55.7% of patients, who had a history of allergy, reported a suspected food-related allergy, 24.6% a drug-related allergy and 8.2% a hymenoptera venom-related allergy. In 76.5% of patients who reported a history of food allergy, food was the presumed elicitor of anaphylaxis. For patients with history of drug allergy, 88.2% had a presumed drug anaphylaxis at the time of presentation at the ED. 81% of cases presented with grade 4 or 5 anaphylaxis. With increasing age, the severity of anaphylaxis increased. Higher tryptase levels correlated with a higher grade of anaphylaxis.

CONCLUSION

In this Belgian urban population, foods and drugs were by far the most common suspected elicitors of anaphylaxis. Personal history of allergic diseases was present in more than half of the cases.

[Furuncular myiasis: Case report of a cutaneous parasitosis usually considered as an abscess]

Furuncular myiasis is a wel l established cutaneous parasitosis in tropical area. In Europe, most of cases have been described in patients returning from risk areas. We report a case of a 4-year old child with a furuncular lesion on his left thigh considered as an abscess and who was send to emergency department for surgical drainage.

The implementation of preventive devices is always a difficult task to anticipate. It is also difficult to verify the adequacy of resources used to the needs. For this purpose, the Belgian Red Cross created the computer tool collecting administrative information, diagnostic codes, destination of the patient, triage, level of emergency as well as kinetics of admission to the preventive care station. Data analysis in the various types of events confirms the usefulness of prevention devices. Although it can be improved, the tool is reliable and permits a great extent the adaptative means to the needs.

[Aneurysm of the thoracic aorta of traumatic origin: a suspected clinical case]

Dans ce travail nous rapportons le cas d'un homme d'origine africaine du nord, âgé de 51 ans, qui s'est présenté à l'urgence pour des douleurs thoraciques constantes depuis un jour. Dans son anamnèse on note un enrouement de la voix depuis deux mois, une notion d'accident de circulation il y a environ dix ans. Patient sportif, fait de la boxe et travaille comme agent de sécurité dans une boite de nuit. La radiographie du thorax et l'angio-scanner thoracique montrent un volumineux anévrisme non compliqué de la crosse et du tiers distal de l'aorte thoracique descendante (7cmx7.8cm en vue axiale). Le patient a bénéficié d'une cure chirurgicale de ce volumineux anévrisme de l'aorte thoracique. Nous discutons des étiologies, des mesures cliniques et para cliniques qui permet le diagnostic de cette entité clinique rare pouvant être une erreur diagnostique pour un médecin urgentiste.

[Rational approach and management of the dyspnoeic patient in general medical practice]

Dyspnea represents 3-4 % of consultations at primary care medicine (general medicine, emergency medicine) and is found in 14 % of the interviewed general population. It is defined as an abnormal and uncomfortable breathing and can be classified according to the mode of appearance, the breathing pattern or the rhythm. Different classifications are used to specify the severity of the situation: visual analog scale, functional classification of the New York Heart Association, dyspnea modified scale from the Medical Research Council, ... Rare among young people, dyspnea often hides asthma; more prevalent among seniors, it is often secondary to chronic lung or heart disease. The rational approach is the same in general medicine and in the emergency room. The management starts with an assessment of the severity of the patient's clinical situation, via the early warning score. The critical patient requires to be managed according to the progressive and cyclical ABCDE approach. For non-critical patients, a traditional approach and a reasoned method are needed. In patients suffering from chronic obstructive pulmonary disease (COPD), the use of the Anthonissen criteria allows to orient toward a pulmonary superinfection or another cause of worsening dyspnea (cardiac, ...). In case of suspected pulmonary embolism, the Geneva score and the modified Wells score help to separate low, intermediate or high probability cases of pulmonary embolism. D-dimers have a very good negative predictive value in the low and middle risk group and pulmonary CT angiography applies only to a smaller group of dyspnoeic patients with a high probability of pulmonary embolism. Echocardiography has a prominent role to assess the LV systolic function, the search for pulmonary artery hypertension, the vascular filling state, etc. We speak of psychogenic dyspnea after having excluded the potentially serious pathologies.

Computer tomography imaging of an unusual cause of appendicitis: a case report

Foreign body occlusion of appendices lumen is a quite rare cause of appendicitis due to foreign body. We present a case of a 63-year-old male who presented with right lower quadrant pain since 24 hours. Computed tomography (CT) demonstrated an acute appendicitis due to a metallic foreign body which was found to be a bullet.

Autre cause de mort subite du nourrisson: à propos d’un cas clinique de syndrome du QT long congénital

Le syndrome du QT long congénital est une maladie rythmique liée à une mutation génétique et caractérisée par un espace QT allongé sur l’électrocardiogramme, des arythmies malignes type torsade de pointe et fibrillation ventriculaire entraînant une mort subite. Les gènes impliqués dans ces mutations codent pour des sous unités des canaux ioniques responsables de l'activité électrique cardiaque. Le diagnostic est basé sur l’électrocardiogramme, une enquête familiale et l’étude génétique. Le traitement repose sur les bêtabloquants, la sympathectomie et le stimulateur cardiaque. Nous rapportons le cas d'un nourrisson de 2 ans retrouvé en état de mort apparente. Nous discutons de sa prise en charge initiale, de l'enquête familiale et de son suivi ultérieur.

[Prospective study of waiting time delays in a university hospital emergency department with a physician triage model]

To measure waiting time delays of patients and to evaluate if the waiting time before the first physician contact is inversely correlated to the illness severity. During the period of 26/02/2007 through 3/03/2007, we prospectively studied the waiting times before the first contact with a physician (WTP) and the length of stay (LS) in 473 patients (0.8% of the annual patient volume) evaluated in our emergency department, which has a physician triage model. The WTP was correlated to a severity score "Clinical Classification of Patients in Emergency (CCPE)". The median WTP was: 48 (22-79) min. (minutes) (median, P25, P75). This time was 33 (14-47), 16 (3-28) and 3 (0-3) min. for patients having a CCPE score of 3, 4 and 5. The median LS was 119 (76-186) min. In conclusion, the waiting times are comparable to those measured in similar studies. The waiting time evaluated according to CCPE is adequate.

Chemical submission to commit robbery: a series of involuntary intoxications with flunitrazepam in Asian travellers in Brussels

Between January 17, 2003 and August 29, 2003, the Emergency Department admitted a patient who had been surreptitiously intoxicated and robbed of his valuables every Friday. The first cases were considered anecdotal, but criminal activity was rapidly suspected. The cohort includes 16 male Asian patients aged 28-50 years. All the victims had just arrived in Brussels through one of the main rail station of the town and were admitted via the emergency ambulance service from different locations in the centre of Brussels around the CHU Saint-Pierre Hospital. Haemodynamic parameters upon admission were within normal limits. The Glasgow Coma Scale was equal or higher than 9/15 in 14 of the 16 victims. Toxicology screening obtained in 12 patients revealed the presence of flunitrazepam, which was further quantified at levels ranging from 21 to 75 μg/l. One of the Japanese patients, who returned to Belgium afterwards for professional reasons, was approached by the police and accepted to press charges. This allowed the police to investigate and send undercover agents to the railway station on Friday afternoons and evenings. They found a person who was offering welcome cookies to Asian travellers. He arrived from Amsterdam and returned once his crime was committed. Flunitrazepam is well known as a rape drug. We report a series of victims in whom flunitrazepam was used to facilitate robbery.

Penetrating cardiac injuries in Belgium: 20 years of experience in university hospitals in Brussels

BACKGROUND

Cardiac wounds remain as highly lethal lesions in which their prognosis depends on the emergency management.

OBJECTIVES

The aim of this study is to analyse experiences of cardiac surgeons in different hospitals in Brussels and compare it with the findings in the literature.

METHODS

From 1st January 1990 till 1st December 2010, all penetrating cardiac wounds in three Brussels hospitals were retrospectively reviewed. Data recorded included clinical parameters, surgical constatation and outcome.

RESULTS

A total of fourteen (12 male/2 female) patients sustained penetrating cardiac injuries. There were thirteen patients (93%) with stabs wounds and, one patient (7%) with gunshot wound. Wound locations are as follows: ten patients (71%) right ventricle, three patients (22%) the pericardium, and one patient (7%) the left ventricle. The hemodynamic status was unstable in nine patients (64%), in-extremis in two patients (14%) and stable in three patients (22%). The mean Abbreviate Injury Score was 4.6 and the mean New Injury Severity Score was 31. Thirteen patients (93%) had operations (11 sternotomie, 2 thoracotomies). Two patients required cardiopulmonary bypass. Three patients (22%) died.

CONCLUSION

Penetrating cardiac wounds are relatively rare in Belgium, which is mainly due to stabs and with consequent mortality. The implementation of clear guidelines is necessary to improve survival.

[Implementation of the therapeutic hypothermia recommendation after resuscitated cardiac arrest caused by ventricular fibrillation and tachycardia without pulse: a retrospective study in Saint-Pierre Hospital]

INTRODUCTION

Therapeutic hypothermia is an essential step for the neurological protection of comatose individuals after cardiorespiratory arrest (CA) and ventricular fibrillation (VF). The evaluation of the application of the Protocol thereto within the C.H.U. Saint-Pierre (SPH) is the subject of this study.

METHOD

Retrospective analyzes of the SPH computerized records from 01/01/2005 to 31/12/2010 whose inclusion criteria are out-of-hospital CA admitted alive to the hospital with VF as initial rythm. Transferred patients or NTBR status are excluded.

RESULTS

Of the 72 patients studied, 68% were discharged alive from the hospital, 84% of which has no neurologic sequelae. Hypothermia was used for 44 people, unduly in 5 cases and there were also 5 other cases for which it was needed, but not applied. Hypothermia (32-34 degrees C) was reached in 11 h 23 (+/- 144 min) and lasted an average of 19 h 51 (+/- 249 min). Hypothermic patient survival amounted to 72.4%, including 81% with good neurological outcome.

CONCLUSION

The results of the protocol application are superior to those of several other studies. Few errors of inclusion and exclusion are present. The implementing of a common protocol for IC--Emergency Units--EMS to accelerate obtaining the target temperature and improve performance seems beneficial. The creation and implementation of a specific register with patients who had AC and were cooled seem interesting for a better medical follow-up, an assessment of the management and an enhancement of the current knowledge related to this technique.

[Patient complaints in a hospital emergency department in Belgium]

Patients express their dissatisfaction through complaints. This study analyzed the frequency and chief complaints of patients presenting to the emergency department (ED). The end point was find ways to improve patient satisfaction after their ED visit. In this retrospective, seven years study, we reviewed 155 chief complaints of patients presenting to the ED of a university hospital. The chief complaints were either from the patients or a family member. One hundred and fifty five chief complaints collected from 496.816 patients presenting to the ED were reviewed over a period of seven years. Complaints case rate was 3.1 per 10.000 visits. Complaints came from patients between the age of 20 to 60 years old (75.0 percent). Complains involved a physician (79.0 percent). The complaints were related a lack of communication (39.0 percent), long waiting time (14.0 percent), wrong diagnosis (22.0 percent), wrong treatment (13.0 percent) and ED disposition of the patient (12.0 percent). Two types of pathology represented more than 15 percent of the complaints: the traumatology (22.0 percent) and the psychiatry (17.0 percent). The traumatology and psychiatry represented respectively 30.0 percent and 10.0 percent of ED visits. Most complaints were addressed and resolved through a hospital mediator, Chief of service or Chief of staff. The rate of complains is low. Most complaints can be prevented if the physician improves communication with patients.

Intra-arrest transnasal evaporative cooling: a randomized, prehospital, multicenter study (PRINCE: Pre-ROSC IntraNasal Cooling Effectiveness)

BACKGROUND

Transnasal evaporative cooling has sufficient heat transfer capacity for effective intra-arrest cooling and improves survival in swine. The aim of this study was to determine the safety, feasibility, and cooling efficacy of prehospital transnasal cooling in humans and to explore its effects on neurologically intact survival to hospital discharge.

METHODS AND RESULTS

Witnessed cardiac arrest patients with a treatment interval <or=20 minutes were randomized to intra-arrest cooling with a RhinoChill device (treatment group, n=96) versus standard care (control group, n=104). The final analysis included 93 versus 101 patients, respectively. Both groups were cooled after hospital arrival. The patients had similar demographics, initial rhythms, rates of bystander cardiopulmonary resuscitation, and intervals to cardiopulmonary resuscitation and arrival of advanced life support personnel. Eighteen device-related adverse events (1 periorbital emphysema, 3 epistaxis, 1 perioral bleed, and 13 nasal discolorations) were reported. Time to target temperature of 34 degrees C was shorter in the treatment group for both tympanic (102 versus 282 minutes, P=0.03) and core (155 versus 284 minutes, P=0.13) temperature. There were no significant differences in rates of return of spontaneous circulation between the groups (38% in treated subjects versus 43% in control subjects, P=0.48), in overall survival of those admitted alive (44% versus 31%, respectively, P=0.26), or in neurologically intact survival to discharge (Pittsburgh cerebral performance category scale 1 to 2, 34% versus 21%, P=0.21), although the study was not adequately powered to detect changes in these outcomes.

CONCLUSIONS

Prehospital intra-arrest transnasal cooling is safe and feasible and is associated with a significant improvement in the time intervals required to cool patients.

[Impact of the mode of arrival in the emergency department for patients with a STEMI and the clinical outcomes in terms of ejection fraction and survival]

Emergency Medical Services (EMSs) play a key role in the recognition and treatment of ST-segment elevation myocardial infarction (STEMI). This study evaluates patient outcome according to his mode of arrival in the care unit dealing with acute coronary syndromes.

METHODS

Retrospective analysis of STEMI infarctions registered by the Belgian Interdisciplinary Working Group on Acute Cardiology (BIWAC) at Saint-Pierre University Hospital, Brussels (C.H.U. Saint-Pierre), between 01/01/2005 and 31/12/2006. Comparison of two groups according to their arrival in the care system: group 1: brought in following an emergency call by mobile medical team (SMUR) or normal ambulance ; group 2: arrived at the hospital by their own means and classic admission to Emergency Service.

STUDIED PARAMETERS

descriptive patient characteristics, localisation of the infarction and survival to the end of hospitalization, to six months and to one year.

RESULTS

Among 136 patients, 56.6 % arrived by EMS and 43.4 % by their own means. Patients who arrived by EMS were older (p = 0.008) and had a higher Killip score (p < 0.05). Pain-to-Angiography and Door-to-Angiography intervals were shorter in patients who arrived by EMS (222 vs 416 mins, p < 0.0001 and 62.6 vs 147 mins, p < 0.0001, respectively). There were no differences in the left ventricular ejection fraction (LVEF) and survival. However, for patients suffering an IVA attack, survival to six months and one year was better in the EMS group (88.9% vs 78.3%, p < 0.05 and 80.5 % vs 69.6 %, p = 0.05). In conclusion, dealing with STEMI infarctions is quicker by EMS admission. The infarctions admitted by this way are more serious. Wherever STEMI infarctions were localised, no improvement of LV function and survival was observed according to the mode of arrival, contrary to the subgroup with an IVA attack where survival is better at six months and one year by EMS admission.
