RESUMO
INTRODUCTION: One of the factors contributing to ED crowding is the lengthy delay in transferring an admitted patient from the ED to an inpatient department (ie, boarding time). An earlier start of the admission process using an automatic hospitalisation prediction model could potentially shorten these delays and reduce crowding. METHODS: Clinical, operational and demographic data were retrospectively collected on 80 880 visits to the ED of Rambam Health Care Campus in Haifa, Israel, from January 2011 to January 2012. Using these data, a logistic regression model was developed to predict patient disposition (hospitalisation vs discharge) at three progressive time points throughout the ED visit: within the first 10 min, within an hour and within 2 hours. The algorithm was trained on 50% of the data (n=40 440) and tested on the remaining 50%. RESULTS: During the study time period, 58 197 visits ended in discharge and 22 683 in hospitalisation. Within 1 hour of presentation, our model was able to predict hospitalisation with a specificity of 90%, sensitivity of 94% and an AUCof 0.97. Early clinical decisions such as testing for calcium levels were found to be highly predictive of hospitalisations. In the Rambam ED, the use of such a prediction system would have the potential to save more than 250 patient hours per day. CONCLUSIONS: Data collected by EDs in electronic medical records can be used within a progressive modelling framework to predict patient flow and improve clinical operations. This approach relies on commonly available data and can be applied across different healthcare settings.

PURPOSE: To evaluate compliance with a management strategy for use in emergency department (ED) patients with suspected deep vein thrombosis (DVT) based on Wells score (WS), D-dimer concentrations, and sonographic (US) examinations. METHODS: Retrospective and prospective data on risk factors, physical examination findings, D-dimer concentrations, and US results were collected and reviewed. The prevalence of DVT for each WS category and D-dimer level was calculated. RESULTS: In the retrospective part of the study, 475 consecutive patients were included. Patients' risk for DVT was scored as high (n = 129 [27.2%]), moderate (n = 95 [20%]), or low (n = 251 [52.8%]). D-Dimer test results were available for 34 (7.2%) of the patients. DVT was diagnosed in 105 (22.1%) patients: 99 (76.7%) at high, 4 (4.2%) at moderate, and 2 (0.8%) at low risk. The mean D-dimer concentration was 3,071.7 ng/ml in patients with DVT. In the prospective part of the study, 50 patients were enrolled. Their risk levels for DVT were scored as high (n = 23 [46%]), moderate (n = 7 [14%]), and low (n = 20 [40%]). D-Dimer testing was performed in all patients. The mean D-dimer concentration was 2,966.9 ng/ml in patients with DVT. DVT was diagnosed in 13 (26%) of these 50 patients: 12 (52.2%) at high and 1 (14.3%) at moderate risk for DVT. No patients in the low-risk group and with normal D-dimer concentrations had DVT. CONCLUSIONS: We identified significant correlation between WS, D-dimer concentration, and diagnosis of DVT on US examination. DVT can be excluded with certainty in patients admitted to the ED with a low-risk score for DVT and a negative D-dimer concentration, thus avoiding the need for performing US examinations. A low level of compliance with this management strategy was found in our ED.

INTRODUCTION: Boarding patients awaiting hospitalization in the emergency department increases mortality and complications, and stands in contrast to the recommendations of emergency medicine associations worldwide. Although Israel's Ministry of Health and the media are addressing the issue, boarding patients in emergency departments is common in hospitals throughout the country. There are no current studies that assess the influence of boarding in emergency departments on the patient's mortality and hospitalization. In 2011, a decision was made in our hospital to board patients in a separate section of the emergency department due to the lack of beds in the inpatient wards. AIMS: This study aimed to demonstrate the scale of boarding patients in a tertiary hospital in Israel and its influence on mortality and length of hospitalization. We examine effects of a deliberate boarding policy on mortality and describe the boarding phenomena, and its causes, to Israeli physicians. STUDY METHODS: This is a retrospective study, comparing patients hospitalized through the emergency department to internal medicine wards in a tertiary hospital during three consecutive years, and studying the effects of deliberate boarding policy in the emergency department on mortality and length of stay [LOS] in the hospital. RESULTS: Roughly half the patients stayed in the emergency department for more than 10 hours. The mortality of patients during the year they were deliberately boarded in a separate section in the emergency department was significantly higher than in other years, when such policy did not take place. A direct link was demonstrated between LOS in the emergency department and mortality. LOS of patients who died was significantly higher than that of patients who did not die. CONCLUSIONS: Boarding patients in the emergency department increases mortality and LOS. Ways to minimize the phenomena should be explored. DISCUSSION: For the first time, the effects of boarding patients in the emergency department in Israel are studied. The issue of boarding patients in emergency departments should be a central issue addressed by Israel's health system.

Since 1987, with the introduction of the first commercial energy drink in Europe, the level of sale of these drinks increased rapidly throughout the western world. These drinks are based on caffeine that is found in them ndependently, and in other ingredients. Other ingredients in these drinks potentiate the effects of caffeine. Caffeine acts in the organism through inhibition and activation of various receptors, and thus affects almost all the body systems. There is an increasing body of evidence about the medical hazards of uncontrolled use of these drinks, with neurologic, psychiatric, cardiovascular and metabolic complications. There is a direct link between use of energy drinks and abuse of alcohol and drugs. Due to the above, health authorities in Israel and around the world have started addressing the regulatory, medical and informative aspects of the issue. In spite all of the above, there is lack of awareness of the public and medical teams about the hazards of cousuming these drinks.

We report a case of left-sided perforated acute appendicitis in the patient with midgut malrotation. Embryology, clinical findings, and radiological presentation are discussed. Highly prevalent disease presents here in the unusual location and thus in the unusual presentation. The emergency room physician and radiologist should be aware of these unique clinical presentations so that appropriate surgical intervention may be initiated promptly.

PURPOSE: Creation of a temporary ostomy is a surgical tool to divert stool from a more distal area of concern (anastomosis, inflammation, etc). To provide a true benefit, the morbidity/mortality from the ostomy takedown itself should be minimal. The aim of our study was therefore to evaluate our own experience and determine the complications and mortality of stoma closure in relation to the type and location of the respective ostomy. METHODS: Patients undergoing an elective takedown of a temporary ostomy at our teaching institution between January 1999 and July 2005 were included in our analysis, and the medical records were retrospectively reviewed. Excluded were only patients with relevant chart deficiencies and nonelective stoma revisions/takedowns. Data collected included general demographics; the type and location of the stoma; the operative technique; and the type, timing, and impact of complications. Perioperative morbidity was defined as complications occurring within 30 days from the operation. RESULTS: 156 patients (median age 45 years, range 18-85) were included in the analysis: 31 loop and 59 end colostomy reversals and 56 loop and 10 end ileostomy takedowns. Mean follow-up was 6 months. The overall mortality rate was low (0.65%, 1/156 patients). However, the morbidity rate was 36.5% (57 patients), with 6 (3.8%) systemic complications and 51 (32.7%) local complications. Minor would infection (34 patients, 21.8%) and postoperative ileus (9 patients, 5.7%) were the most common surgery-related complications, but they generally resolved with conservative management. Anastomotic leak and formation/persistence of an enterocutaneous fistula (6 patients, 3.8%) were the most serious local complications and required reintervention in all of the patients. Closure of a loop colostomy accounted for half and Hartmann reversals for one third of these complications, as opposed to ileostomy takedowns, which accounted for only one sixth (1.8% absolute risk). CONCLUSION: Takedown of a temporary ostomy has a low mortality but a nonnegligible morbidity. The stoma location (large vs. small bowel) has a higher impact than the type of stoma construction (end vs. loop) on the incidence and severity of complications.

INTRODUCTION: Distal radius fractures (DRFs) are treated in the emergency department (ED) with a closed reduction in order to decrease neurovascular and soft tissue injury and as a first definitive step in conservative treatment. The type of anesthesia used may affect the ability to reduce the fracture and remains controversial. OBJECTIVE: The purpose of this study was to compare the quality of radiographic reduction achieved in the ED of DRF reduced using sedation anesthesia to those reduced with hematoma block anesthesia. METHODS: A retrospective case-control study of 240 DRF reductions, 30 treated with sedation and 210 with a hematoma block, was performed. Complications and time spent in the ED were documented. Pre- and postreduction radiographs were reviewed for volar tilt, radial angulation, radial height, and ulnar variance. RESULTS: Both groups were similar in gender, background illnesses, concomitant injuries, surgeon experience, and fracture radiographic classification. Postreduction values of volar tilt were better in the sedation group (P = .03). Volar tilt and ulnar variance improved more in the sedation group (P = .001). The sedation group spent more time in the ED (P = .001). DISCUSSION: Sedation seemed to be more efficient than hematoma block in supporting closed reduction of distal radius fractures in the ED. However, this method requires specialized personnel and more time spent in the ED. CONCLUSION: We suggest using this method when the patient is planned to continue with conservative treatment.
HISTORIQUE: Les fractures distales du radius (FDR) sont traitées en salle d'urgence (SU) au moyen d'une réduction fermée afin de réduire les lésions neurovasculaires et celles des tissus mous. Cette technique représente la première étape décisive d'un traitement prudent. Le type d'anesthésie privilégié demeure controversé, car il peut influer sur la capacité de réduire la fracture. OBJECTIF: La présente étude visait à comparer la qualité des réductions radiographiques des FDR par sédation obtenues en SU à celles effectuées sous anesthésie locorégionale. MÉTHODOLOGIE: Les chercheurs ont effectué une étude rétrospective cas-témoins de 240 réductions de FDR, dont 30 traitées sous sédation et 210, sous anesthésie locorégionale. Ils ont consigné les complications et le temps passé en SU. Ils ont examiné les radiographies avant et après la réduction pour déterminer l'inclinaison palmaire, la déviation radiale, la hauteur radiale et la variance ulnaire. RÉSULTATS: Le sexe, les maladies antérieures, les lésions concomitantes, l'expérience du chirurgien et la classification radiographique des fractures étaient semblables dans les deux groupes. Les valeurs de l'inclinaison palmaire après la réduction étaient supérieures dans le groupe sous sédation (p=0,03). L'inclinaison palmaire et la variance ulnaire s'amélioraient également davantage dans ce groupe (p=0,001), qui passait toutefois plus de temps en SU (p=0,001). EXPOSÉ: La sédation semblait plus efficace que l'anesthésie locorégionale lors de la réduction fermée des fractures distales du radius en SU. Cependant, cette méthode exige la présence de personnel spécialisé et une période plus longue en SU. CONCLUSION: Les chercheurs suggèrent d'utiliser la sédation lorsqu'il est prévu que le patient poursuive un traitement prudent.

BACKGROUND: Dyspnea is one of the most common complaints facing the emergency medicine physician. Some of the gastrointestinal causes of dyspnea are self-limited and not life-threatening, yet others are, and early diagnosis and treatment are crucial. METHODS: In this article we presented one of these life-threatening conditions through a clinical description of a patient presenting with acute respiratory distress that was finally diagnosed to be the result of a perforated gastric ulcer. RESULTS: An emergent thoracotomy revealed a small ulcer with perforation in the fundus of the stomach. The patient was transferred after the operation to the intensive care unit and after a prolonged hospitalization discharged home. Biopsies taken from the ulcer showed diffuse inflammation, with no evidence of microorganisms or malignancy. CONCLUSION: Perforation of gastric and duodenal ulcers is a rare yet existing cause of dyspnea and respiratory failure and should be kept in mind by the emergency physician, especially when other more common causes are ruled out.
RESUMO
Objectives. To evaluate the viability of the possibility to use a higher D-dimer value than the one used today in the clinical algorithms evaluating patients suspected to have pulmonary embolism. Methods. A retrospective analysis of 300 serial patients for whom D-dimer values were taken during a 10 month period in the emergency room of a tertiary medical center. Results. Our analysis showed that it may be safe and cost effective to use a D-dimer value of 900 ng/ml rather than the value of 500 ng/ml accepted today, with sensitivity of 94.4%. In younger patients [under 40 years] the sensitivity reached was even higher-100%. Conclusions. Raising cutoff values of D-dimer in screening for pulmonary embolism seems a viable option. There may be a place for "tailoring" cutoff values according individual patient characteristics, such as according age groups. More studies of the subject are warranted.
RESUMO
BACKGROUND: Caffeinated energy drinks are widely used worldwide. They are associated with a variety of adverse effects and are of concern to health authorities, yet there is still scarce information about their adverse effects and inadequate awareness among medical personnel. METHODS: Case description and discussion of a patient presenting to the emergency room after overdose of energy drinks in combination with 3,4-methylenedioxymethamphetamine (MDMA). RESULTS: Despite best medical efforts, the patient died of fatal cardiac arrhythmias. There is a paucity of information about adverse effects of energy drinks. CONCLUSION: Although energy drinks are widely used, there is a lack of awareness in the population and medical staff about their hazards.

PURPOSE: Focused helical CT using rectal contrast material only has emerged recently as an accurate diagnostic tool for the evaluation of suspected acute appendicitis. This study was designed to prospectively compare the efficacy of rectal contrast CT to other commonly used contrast-enhanced and nonenhanced CT techniques for the detection of acute appendicitis. METHODS: A total of 232 patients with clinically suspected appendicitis were randomly assigned to one of three focused helical CT techniques: noncontrast enhanced CT, CT using rectal contrast material only, and dual-contrast CT using both oral and intravenous material. All scans were interpreted by the on-call residents and reported immediately to the surgeon. The sensitivity, specificity, predictive values, and overall accuracy rates were compared between the protocols. RESULTS: One hundred eleven patients (48 percent) had acute appendicitis. The sensitivity and specificity rates of rectal contrast CT were 93 and 95 percent, respectively, with overall accuracy of 94 percent. The sensitivity and specificity rates of dual-contrast CT were 100 and 89 percent, respectively, with overall accuracy of 94 percent. The sensitivity and specificity of noncontrast enhanced CT were 90 and 86 percent, respectively, but the overall accuracy was significantly lower (70 percent) compared with the other studies. CONCLUSIONS: Rectal contrast CT is as accurate, although less sensitive, compared with dual-contrast CT and significantly superior to noncontrast-enhanced CT for the diagnosis of acute appendicitis. Rectal contrast CT may be performed rapidly, saves resources, and may avoid the diagnostic delay and potential allergic reactions associated with oral and intravenous-enhanced studies, and, therefore, may be the preferred initial technique in the diagnostic workup of suspected acute appendicitis.

BACKGROUND: The management of penetrating abdominal stab wounds has been the subject of continued reappraisal and controversy. In the present study a novel method which combines the use of diagnostic laparoscopy and DPL, termed laparoscopic diagnostic peritoneal lavage (L-DPL) is described METHOD: Five trauma patients with penetrating injuries to the lower chest or abdomen were included. Standard videoscopic equipment is utilized for the laparoscopic trauma evaluation of the injured patient. When no significant injury is detected, the videoscope is withdrawn and 1000 mL of normal saline is infused through the abdominal trochar into the peritoneal cavity, and the effluent fluid studied for RBCs, WBC, amylase debry, bile as it is uced in regular diagnostic peritoneal lavage RESULTS: Laparoscopic peritoneal lavage (L-DPL) was then performed and proved to be negative in all 5 patients. RBC lavage counts above 100,000/mcrl were not considered as a positive lavage result, because the bleeding source was directly observed and controlled laparoscopically. All patients recovered uneventfully and were released within 3 days. This procedure combines the visual advantages of laparoscopy together with the sensitivity and specificty of DPL for the diagnosis of significant penetrating intra-abdominal injury, when the diagnostic strategy of selective consevatism for abdominal stab wounds is adopted. CONCLUSION: A method of laparoscopic diagnostic peritoneal lavage (L-DPL) in hemodynamically stable patients with penetrating lower thoracic or abdominal stab wounds is described. The method is especially applicable for trauma surgeons with only basic experience in laparoscopic technique. This procedure is used to obtain conclusive evidence of significant intra-abdominal injury, confirm peritoneal penetration, control intra-abdominal bleeding, and repair lacerations to the diaphragm and abdominal wall. The combination of laparoscopy and DPL afforded by the L-DPL method adds to the sensitivity and specificity of DPL, and avoids under or over sesitivty, that have limited the use of DPL in the hemodynamically stable trauma patients with suspicious or proven peritoneal penetration.
