RESUMEN
Introduction: Clinical decision tools have been shown to reduce imaging rates for clearance of suspected cervical spine injury (CSI). This review provides more comprehensive evidence on the diagnostic capabilities of National Emergency X-Radiography Utilization Study (NEXUS) and Canadian C-spine rule (CCR) in this regard. Method: A systematic review of the current literature was performed on studies published until Jan 26th, 2023, in databases of Medline, Scopus, Web of Science, and Embase, investigating the performance of NEXUS and CCR in blunt trauma patients. QUADAS-2 and GRADE guidelines were used to assess the quality and certainty of evidence. All analyses were performed using the STATA 14.0 statistical analysis software. Results: 35 articles comprising 70000 patients for NEXUS and 33000 patients for CCR were included in this review. NEXUS and CCR were evaluated to have a sensitivity of 0.94 (95% confidence interval (CI): 0.88 to 0.98) and 1.00 (95% CI: 0.98 to 1.00) in the detection of any CSI and 0.95 (95% CI: 0.89 to 0.98) and 1.00 (95% CI: 0.95 to 1.00) in the detection of clinically important CSI. The area under the curve (AUC) of NEXUS and CCR was 0.85 and 0.97 for any CSI and 0.78 (95% CI: 0.74 to 0.81) and 0.94 (95% CI: 0.91 to 0.96) for clinically important CSI. Conclusion: Our study demonstrates that both NEXUS and CCR can be used in ruling out patients with low risk of CSI, and CCR was shown to have superior performance. Even though these tools have low specificity, their application can still greatly reduce the number of radiographic imaging performed in emergency departments.
RESUMEN
Various severe acute respiratory syndrome coronavirus 2 vaccines with different platforms have been administered worldwide; however, their effectiveness in critical cases of COVID-19 has remained a concern. In this national cohort study, 24 016 intensive care unit (ICU) coronavirus disease-2019 (COVID-19) admissions were included from January to April 2022. The mortality and length of ICU stay were compared between the vaccinated and unvaccinated patients. A total of 9428 (39.25%) patients were unvaccinated, and 14 588 (60.75%) patients had received at least one dose of the vaccine. Compared with the unvaccinated, the first, second, and third doses of vaccine resulted in 8%, 20%, and 33% lower risk of ICU mortality in the adjusted model, with risk ratio (RR): 0.92, 95% confidence interval (CI): 0.84-1.001, RR: 0.80, 95% CI: 0.77-0.83, and RR: 0.67, 95% CI: 0.64-0.71, respectively. The mean survival time was significantly shorter in the unvaccinated versus the fully vaccinated patients (hazard ratio [HR]: 0.84, 95% CI: 0.80-0.88); p < 0.001). All vaccine platforms successfully decreased the hazard of ICU death compared with the unvaccinated group. The duration of ICU stay was significantly shorter in the fully vaccinated than in unvaccinated group (MD, -0.62, 95% CI: -0.82 to -0.42; p < 0.001). Since COVID-19 vaccination in all doses and platforms has been able to reduce the risk of mortality and length of ICU-stay, universal vaccination is recommended based on vaccine availability.

BACKGROUND: Witnessing or experiencing of incivility affected the nurses' perception of the ethical climate and quality of their work life. The aim of this study was to investigate the effectiveness of educational intervention and cognitive rehearsal on perceived incivility among emergency nurses. METHOD: This study was conducted as a randomized controlled parallel group clinical trial. Eighty emergency nurses participated in this study and were randomly assigned to intervention and control groups during December 2019-March 2020. Cognitive rehearsal program (include of definitions of incivility, ten common incivilities and appropriate practice methods for responding to each and role-plays) was delivered in five two-hour sessions over three weeks on different working days and shifts. The control group received only written information about what incivility is and how to deal with it before the implementation of intervention and one month after the completion of the training sessions, the demographic information form and the incivility scale were completed by the nurses. RESULTS: The results showed that there was a significant effect on overall incivility, general incivility, and supervisor incivility between the intervention and control groups. However, these significant reductions were seen in control group who received only written education. There were no significant differences in nurse's incivility towards other nurses, physician incivility, and patient/visitor incivility between the two groups. CONCLUSION: The cognitive rehearsal program did not decrease perceived incivility among emergency department nurses in the short term. TRIAL REGISTRATION: Our research was registered on clinicaltrials.gov. REGISTRATION NUMBER: IRCT20200714048104N1 , first registration 16/07/2020.
RESUMEN
Introduction: Early decompression within the first 24 hours after spinal cord injury (SCI) is proposed in current guidelines. However, the possible benefits of earlier decompression are unclear. Thus, the present meta-analysis aims to investigate the existing evidence regarding the efficacy of ultra-early decompression surgery (within 12 hours after SCI) in improving patients' neurological status. Methods: A search was performed in Medline, Embase, Scopus and Web of Science electronic databases, until the end of August 2021. Cohort studies and clinical trials were included in the present study. Exclusion criteria were absence of an early or late surgery group, failure to report neurological status based on the American spinal injury association impairment scale (AIS) grade, failure to perform the surgery within the first 12 hours after SCI, and duplicate reports and review articles. Two independent reviewers performed data collection, and risk of bias and certainty of evidence assessments. The outcome was reported as odds ratio (OR) and 95% confidence interval (CI). Results: Data from 16 articles, which studied 868 patients, were included. Compared to early or late decompression surgery, ultra-early decompression surgery significantly improves patients' neurological status (OR = 2.25; 95% CI: 1.41 to 3.58). However, ultra-early surgery in thoracolumbar injuries is not significantly more effective than early to late surgery. Moreover, ultra-early surgery in patients with a baseline AIS A increases the chance of neurologic resolvent up to 3.86 folds (OR=3.86; 95% CI: 1.50 to 9.91). Contrastingly, ultra-early surgery does not result in significant improvement compared to early to late surgery in patients with AIS B (OR = 1.32; 95% CI: 0.51 to 3.45), AIS C (OR = 1.83; 95% CI: 0.72 to 4.64), and AIS D (OR = 0.99; 95% CI: 0.31 to 3.17). Conclusion: Current guidelines emphasize that spinal decompression should be performed within 24 hours after SCI, regardless of injury severity and location. However, results of the present study demonstrated that certain considerations may be taken into account when performing decompression surgery: 1) in patients with AIS A injury, decompression surgery should be performed as soon as possible, since its efficacy in neurological improvement is 3.86 folds higher in the first 12 hours after injury. 2) ultra-early decompression surgery in patients with cervical injury is more effective than in patients with thoracic or lumbar injuries. 3) postponing decompression surgery to 24 hours in SCI patients with AIS B to D does not significantly affect the neurological outcome.
RESUMEN
Seborrheic keratosis (SK) is a common benign skin epidermal lesion. Different treatment modalities have been proposed for this lesion. This study aimed to compare the efficacy and safety of electrodesiccation, cryotherapy, CO2 laser, and Er:YAG laser in the treatment of SK. The study was carried out on 30 patients each with four similar facial SKs. Each lesion was assigned to be treated with cryotherapy, electrodesiccation, CO2 laser, and Er:YAG laser in a random fashion. Therapeutic results were evaluated 8 weeks after the interventions through clinical and dermatoscopic assessment. Treatment improvement criteria for each lesion included the texture of the lesion, severity of the pigmentation, and an overall assessment of the healing. The severity of burning, pain, erythema, and the duration of the erythema after the procedures were documented. A survey of the patients' satisfaction with the treatments was also performed. In the assessment of overall lesion healing by two dermatologists, the improvement rate was significantly higher in the CO2, Er:YAG lasers and electrodesiccation group compared to the cryotherapy (p < 0.001). However, the CO2 and Er:YAG laser and the electrodesiccation groups showed no significant difference (p > 0.05). Moreover, no significant difference was observed in posttreatment pigmentation and texture between the groups (p > 0.05). The pain and burning severity after the interventions were negligible in all four groups. Prolonged erythema was not observed in any of the cases; however, the duration of erythema in the Er:YAG laser group was significantly longer (p < 0.001). Patient satisfaction in the cryotherapy group was significantly lower than the other three groups (p < 0.001). The efficacy of treatment and patient satisfaction rate is highly comparable between electrodesiccation, CO2 laser, and Er:YAG laser but significantly higher than cryotherapy.

RESUMEN
INTRODUCTION: Osteomyelitis is one of the complications of diabetic foot infection. The present study aimed to evaluate the diagnostic value of erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) in detection of osteomyelitis in patients with diabetic foot. METHODS: In this cross-sectional study, serum levels of ESR and CRP were measured for patients with diabetic foot referring to emergency department or endocrinology clinic and the screening performance characteristics of these markers in detection of osteomyelitis were calculated. The diagnosis of osteomyelitis was based on clinical examination and positive probe-to-bone test, which was confirmed by plain x-rays or MRI. RESULTS: 142 diabetic patients with an average age of 61.2 ± 11.8 years were evaluated (66.2 % male). The area under the ROC curve of ESR in detection of osteomyelitis in diabetic foot cases was 0.70 (95% CI: 0.62-0.79). The best ESR cut-off point in this regard was 49 mm/hour. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of ESR in 49 mm/Hour cut-point were 74.6% (95% CI: 62.9-83.9), 57.7% (95% CI: 45.5-69.2), 63.9% (95% CI: 52.5-73.9), 69.5 % (95% CI: 56.0-80.0), 1.8 (95% CI: 1.3-2.4) and 0.4 (95% CI: 0.3-0.7), respectively. The area under the ROC curve of CRP in detection of osteomyelitis was 0.67 (95% CI: 0.58-0.76). The best cut-off point for CRP in this regard was 35 mg/liter with sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios of 76% (95% CI: 64.2-85), 54.9% (95% CI: 42.7-66.6), 62.8% (95% CI: 51.6-72.8), 69.6% (95% CI: 51.7-80.8), 1.7 (95% CI, 1.3-2.2), and 0.4 (95% CI: 0.3-0.7), respectively. CONCLUSION: Based on the findings of ROC curve analysis, ESR and CRP had fair and poor accuracy, respectively, in detecting the diabetic foot cases with osteomyelitis.
RESUMEN
BACKGROUND: We aimed to examine the available evidence regarding the efficacy and safety of corticosteroids on the management of coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV). METHOD: An extensive search was conducted in Medline, Embase, and Central databases until the end of March 2020, using keywords related to corticosteroids, COVID-19, SARS-CoV and MERS-CoV. The main outcome was considered to be the mortality rate, length of stay, virus clearance time, symptom improvement, and lung function improvement. The findings are presented as odds ratio (OR) with 95% confidence interval (95% CI). RESULTS: Fifteen paper compromising 5 studies on COVID-19, 8 studies on SARS-CoV and 2 studies on MERS-CoV were included. One study was clinical trial and the rest were cohort. The analyses showed that corticosteroids were not reduce the mortality rate of COVID-19 (OR=1.08; 95% CI: 0.34 to 3.50) and SARS-CoV (OR=0.77; 95% CI: 0.34 to 1.3) patients, while they were associated with higher mortality rate of patients with MERS-CoV (OR = 2.52; 95% CI: 1.41 to 4.50). Moreover, it appears that corticosteroids administration would not be effective in shortening viral clearance time, length of hospitalization, and duration of relief symptoms following viral severe acute respiratory infections. CONCLUSION: There is no evidences that corticosteroids are safe and effective on the treatment of severe acute respiratory infection when COVID-19 disease is suspected. Therefore, corticosteroids prescription in COVID-19 patients should be avoided.
RESUMEN
INTRODUCTION: Abdominal aortic aneurysm (AAA, triple A) is one of the less common but important causes of abdominal pain. This study aimed to evaluate the characteristics and outcome of patients presenting to emergency department with triple A. METHODS: In this retrospective cross-sectional study, all cases with confirmed triple A, who were presented to the emergency department of Shohadaye Tajrish Hospital, Tehran, Iran from 2006 to 2017 (10 years) were enrolled using census sampling method. RESULTS: 500 cases with the mean age of 68.11 ± 11.98 (25 - 94) years were studied (84% male). The mean duration of symptoms was 2.32 ± 9.58 months and mean aneurysmal size was 63.91 ± 20.08 mm. In 4 (0.8 %) cases, atrial fibrillation (AF) was found during cardiac monitoring. Patients stayed in the hospital for an average of 7.06 ± 6.32 days. Aneurysmal leak was seen in 130 (26%) cases based on abdominal computed tomography (CT) scan findings. 369 (73.8%) cases underwent aneurysmorrhaphy, 126 (25.2%) were treated with non-surgical approaches, and 5 (1%) underwent grafting. 104 (20.8%) died and 396 (79.2%) were treated successfully. Older age (p = 0.017), shock state at the time of presentation (p < 0.0001), leakage of aneurysm (p < 0.001), larger size of aneurysm (p = 0.024), and aneurysmorrhaphy (p < 0.001) were among the factors significantly associated with mortality. CONCLUSION: Based on the findings, the most frequent presenting symptom of patients was abdominal pain. The mortality rate of this series was 21% and older age, shock state, leakage of aneurysm, larger size of aneurysm, and performing aneurysmorrhaphy were among the factors significantly associated with mortality.
RESUMEN
INTRODUCTION: Endotracheal suctioning is a method commonly used to clean airway secretions in patients under mechanical ventilation (MV). This study aimed to compare the effects of open and closed suction methods on the occurrence of ventilator associated pneumonia (VAP). METHODS: This comparative study was carried out on adult intensive care unit (ICU) patients in need of MV for more than 48 hours, from October 2018 to January 2019. Patients were randomly allocated to either closed tracheal suction system (CTSS) group or open tracheal suction system (OTSS) group. Patients were monitored for developing VAP within 72 hours of intubation and the findings were compared between groups. RESULTS: 120 cases with the mean age of 57.91±19.9 years were randomly divided into two groups (56.7% male). The two groups were similar regarding age (p = 0.492) and sex (p = 0.713) distribution. 22 (18.3%) cases developed VAP (12 (20%) in OSST group and 10 (16.7%) in CSST; p = 0.637). The most prevalent bacterial causes of VAP were Acinetobacter_Baumannii (72.7%), Klebsiella pneumoniae (18.2%), and Methicillin-Resistant Staphylococcus aureus (9.1%), respectively. There was not any significant difference between groups regarding the mean duration of remaining under MV (p = 0.623), mean duration of hospitalization (p = 0.219), frequency of VAP (p = 0.637), and mortality (p = 0.99). CONCLUSION: It seems that type of endotracheal suction system (OSST vs. CSST) had no effect on occurrence of VAP and other outcomes such as duration of need for MV and ICU stay as well as mortality.
RESUMEN
BACKGROUND: Choosing a proper medication for pain management of patients with acute renal colic has been a challenge for physicians treating these patients. OBJECTIVES: The present study was performed with the aim of comparing intravenous (IV) ibuprofen and IV ketorolac in pain management of these patients. METHODS: In the present double-blind clinical trial study, patients suspected with renal colic presented to the emergency department were randomly divided into 2 groups receiving IV ibuprofen or IV ketorolac and were compared regarding effectiveness (pain reduction 15, 30, and 60 minutes after injection), treatment success, and possible side effects. RESULTS: In total, 240 patients suspected with renal colic with the mean age of 27.38 ± 12.32 years were randomly divided into 2 groups of 120 individuals treated with IV ketorolac or ibuprofen (66.4% male). The two groups were in a similar condition regarding age (P = 0.56), sex (P = 0.78) history of kidney stone (P = 0.40), vital signs (P > 0.05), stone size (P = 0.73), stone location (P = 0.13), and pain severity on admission (P = 0.32). 15, 30, and 60 minutes after drug injection, pain severity in the ketorolac group was significantly higher than the group receiving ibuprofen (P < 0.0001 for all comparisons), yet these differences were not clinically significant. Fifteen minutes after the injection, the rate of treatment success was significantly higher in the group receiving IV ibuprofen (P < 0.0001). After 60 minutes, the number of completely relieved cases reached 37 (30.8%) patients in the ketorolac group and 83 (69.1%) patients in the ibuprofen group. No significant difference was seen in side effects between the two groups (P = 0.35). CONCLUSIONS: The findings of the present study show that ibuprofen is a more rapid acting drug compared to ketorolac in controlling pain caused by renal colic. In addition, its rate of complete relief from pain was twice as much as that of ketorolac. Since the side effects observed for ibuprofen in the present study were very mild, it is suggested to use this drug in treatment and pain control of renal colic patients.
RESUMEN
INTRODUCTION: Elimination of preventable deaths due to acute kidney injury (AKI) in low-income countries by 2025 is an important healthcare goal at the international level. The present study was designed with the aim of evaluating the prevalence and outcome of AKI in patients presenting to emergency department. METHODS: The present cross-sectional, retrospective study was performed on patients that presented to the emergency departments of 3 major teaching hospitals, Tehran, Iran, between 2005 and 2015 and were diagnosed with AKI. Patient selection was done using consecutive sampling and required data for this study was extracted by referring to the medical profiles of the patients and filling out a checklist designed for the study. RESULTS: 770 AKI patients with the mean age of 62.72 ± 19.79 (1 - 99) years were evaluation (59.1% male). 690 (89.61%) cases of AKI causes were pre-renal or renal. Among the pre-renal causes, 74 (73.3%) cases were due to different types of shock (p < 0.001). The most common etiologic causes of AKI in pre-renal group were hypotension (57.3%) and renal vascular insufficiency (31.6%). In addition, regarding the renal types, rhabdomyolysis (35.0%), medication (17.5%) and chemotherapy (15.3%) and in post-renal types, kidney stone (34.5%) were the most common etiologic causes. 327 (42.5%) patients needed dialysis and 169 (21.9%) patients died. Sex (p = 0.001), age over 60 years (p = 0.001), blood urea nitrogen level (p < 0.001), hyperkalemia (p < 0.001), metabolic acidosis (p < 0.001), cause of failure (p = 0.001), and type of failure (p = 0.009) were independent risk factors of mortality. CONCLUSION: The total prevalence of AKI in emergency department was 315 for each 1000000 population and preventable mortality rate due to AKI was estimated to be 28.2 cases in each 1000000 population. The most important preventable AKI causes in the pre-renal group included shock, sepsis, and dehydration; in the renal group they included rhabdomyolysis and intoxication; and stones in the post-renal group.
RESUMEN
PURPOSE: It is essential to adjust the responsibilities and function of medical education offices (MEOs) in regard to the current societal requirements. Therefore, it is a good idea to learn lessons from the experiences about the establishment and function of these offices around the world. The aim of the present study was to carry out a comparative study to investigate the function and structure of MEOs at some of the medical universities from America, Europe, and Asia. SUBJECTS AND METHODS: This is a comparative, descriptive study that was conducted in 2015. Eleven offices around the world (in America, Europe, and Asia) were selected for the study. Expert group discussion and literature review were used in order to select research sample. The data were gathered using self-constructed checklists. Content and face validity of the checklist was assessed by gathering feedback from experts. The Kappa coefficient was used to determine the inter-rater reliability. RESULTS: All the 11 offices in our study (100%) dealt with the issues of faculty development and research and scholarship activities. Only one out of the 11 offices (27%) dealt with the issues of society and patient education. Five out of the 11 offices (36%) dealt with the continuing medical education and continuing professional development. Consultation services are provided at seven of the 11 offices (64%). CONCLUSIONS: This study revealed both commonalities and differences in the function and structure of MEO among the 11 offices we examined. Based on this study, effective goals and strategies for MEO can be recommended.
RESUMEN
OBJECTIVE: This study was conducted to assess the correlation between central venous pressure (CVP) and venous blood gas (VBG) analysis parameters, to facilitate management of severe sepsis and septic shock in emergency department. MATERIAL AND METHODS: This diagnostic study was conducted from January 2014 until June 2015 in three major educational medical centers, Tehran, Iran. For patients selected with diagnosis of septic shock, peripheral blood sample was taken for testing the VBG parameters and the anion gap (AG) was calculated. All the mentioned parameters were measured again after infusion of 500 cc of normal saline 0.9% in about 1 h. RESULTS: Totally, 93 patients with septic shock were enrolled, 63 male and 30 female. The mean age was 72.53 ± 13.03 and the mean Shock Index (SI) before fluid therapy was 0.79 ± 0.30. AG and pH showed significant negative correlations with CVP, While HCO3 showed a significant positive correlation with CVP. These relations can be affected by the treatment modalities used in shock management such as fluid therapy, mechanical ventilation and vasopressor treatment. CONCLUSION: It is likely that there is a significant statistical correlation between VBG parameters and AG with CVP, but further research is needed before implementation of the results of this study.
RESUMEN
INTRODUCTION: Electrolyte imbalances are very common among crushed earthquake victims but there is not enough data regarding their trend of changes. The present study was designed to evaluate the trend of changes in sodium, calcium, and phosphorus ions among crush syndrome patients. METHODS: In this retrospective cross-sectional study, using the database of Bam earthquake victims, which was developed by Iranian Society of Nephrology following Bam earthquake, Iran, 2003, the 10-day trend of sodium, calcium, and phosphorus ions changes in > 15 years old crush syndrome patients was evaluated. RESULTS: 118 patients with the mean age of 25.6 ± 6.9 years were studied (57.3 male). On the first day of admission, 52.5% (95% CI: 42.7 - 62.3) of the patients had hyponatremia, which reached 43.9% (95% CI: 28.5 - 59.3) on day 10. 100.0% of patients were hypocalcemic on admission and serum calcium level did not change dramatically during the 10 days of hospitalization. The prevalence of hyperphosphatemia on the first day was 90.5% (95% CI: 81.5 - 99.5) and on the 10th day of hospitalization 66.7% (95% CI: 48.5 - 84.8) of the patients were still affected. CONCLUSION: The results of the present study shows the 52.5% prevalence of hyponatremia, 100% hypocalcemia, and 90.5% hyperphosphatemia among crush syndrome patients of Bam earthquake victims on the first day of admission. Evaluation of 10-day trend shows a slow decreasing pattern of these imbalances as after 10 days, 43.9% still remain hyponatremic, 92.3% hypocalcemic, and 66.7% hypophosphatemic.
RESUMEN
INTRODUCTION: The prevalence of behavioral disorders is substantially higher in stressful working environments such as emergency departments. The present study aimed to evaluate the prevalence of personality disorders among emergency nurses. METHODS: In the present epidemiologic study, the prevalence of personality disorders among emergency nurses of three educational hospitals, Tehran, Iran, were evaluated based on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) test. After the questionnaires were filled, data were entered to a special software for MMPI-2 test and the final result was interpreted based on the opinion of a clinical psychologist. Findings were reported using descriptive statistics. RESULTS: 102 emergency nurses with the mean age of 30.2 ± 5.6 years were enrolled (100% female; 100% with master's degree in nursing). The mean working time and experience of studied nurses were 210.8 ± 47.9 hours/month (130-370) and 4.1 ± 3.6 years (1-20), respectively. 32 (31.4%) cases showed symptoms of personality disorders The most common personality disorder detected in this study was somatization with 8.8%, hysteria with 6.9% prevalence, and pollyannaish with 4.9%. Among the studied factors only recent history of unpleasant event has significant correlation with existence of personality disorders (p = 0.015). CONCLUSION: The present study showed that somatization, hysteria, and pollyannaish were the most common personality disorders among the emergency nurses. History of an unpleasant event in the past year was the only effective factor in existence of personality disorders in the studied nurses.
RESUMEN
INTRODUCTION: Road traffic injuries (RTI) are among the most important health problems worldwide as they cause more than 1.2 million deaths and 50 million injuries each year. Therefore, the present study aims to evaluate the outcome and aftermath of RTI in those who were injured and hospitalized due to a traffic accident. METHODS: In the present retrospective cohort study with a one-year follow-up, data were extracted from the profiles of the RTI hospitalized patients. Outcome of the patients was evaluated at the time of discharge and 1-year later including their living state, presence of a disability or complete recovery. RESULTS: 1471 patients were studied (mean age of 32.8±17.0; 80.3% male). 571 (38.8%) had mild disability, 684 (46.5%) moderate disability, and 85 (5.8%) had severe disability at the time of discharge. In the end, 53 (3.6%) died. In the 1-year follow-up, 194 (13.2%) had mild disability, 43 (2.9%) had moderate disability, 9 (0.6%) had severe disability, and 7 (0.5%) were in a vegetative state. Presence of an underlying disease (p=0.03), loss of consciousness for more than 24 hours (p=0.04), spinal injury (p=0.002), presence of multiple trauma (p=0.01), increased ISS (p<0.001), need for ventilator (p<0.001), and organ injuries during hospitalization (p<0.001) are independent factors that increase the risk of poor outcome in RTI patients. CONCLUSION: Based on the results of the present study, underlying illnesses, loss of consciousness for more than 24 hours, spinal injury, multiple trauma, increased ISS, need for ventilator, and organ injuries during hospitalization were independent factors that increased the probability of poor outcome in RTI injuries.
RESUMEN
BACKGROUND: Determining etiologic causes and prognosis can significantly improve management of syncope patients. The present study aimed to compare the values of San Francisco, Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL), Boston, and Risk Stratification of Syncope in the Emergency Department (ROSE) score clinical decision rules in predicting the short-term serious outcome of syncope patients. MATERIALS AND METHODS: The present diagnostic accuracy study with 1-week follow-up was designed to evaluate the predictive values of the four mentioned clinical decision rules. Screening performance characteristics of each model in predicting mortality, myocardial infarction (MI), and cerebrovascular accidents (CVAs) were calculated and compared. To evaluate the value of each aforementioned model in predicting the outcome, sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were calculated and receiver-operating curve (ROC) curve analysis was done. RESULTS: A total of 187 patients (mean age: 64.2 ± 17.2 years) were enrolled in the study. Mortality, MI, and CVA were seen in 19 (10.2%), 12 (6.4%), and 36 (19.2%) patients, respectively. Area under the ROC curve for OESIL, San Francisco, Boston, and ROSE models in prediction the risk of 1-week mortality, MI, and CVA was in the 30-70% range, with no significant difference among models (P > 0.05). The pooled model did not show higher accuracy in prediction of mortality, MI, and CVA compared to others (P > 0.05). CONCLUSION: This study revealed the weakness of all four evaluated models in predicting short-term serious outcome of syncope patients referred to the emergency department without any significant advantage for one among others.
