The McGill Simulation Complexity Score (MSCS): a novel complexity scoring system for simulations in trauma.

BACKGROUND: In medical education, simulation can be defined as an activity in which an individual demonstrates skills, procedures and critical thinking using interactive mannequins in a setting closely resembling the clinical environment. To our knowledge, the complexity of trauma simulations has not previously been assessed. We aimed to develop an objective trauma simulation complexity score and assess its interrater reliability. METHODS: The McGill Simulation Complexity Score (MSCS) was designed to address the need for objective evaluation of the complexity of trauma scenarios. Components of the score reflected the Advanced Trauma Life Support approach to trauma. The score was developed to take into account the severity of trauma injuries and the complexity of their management. We assessed interrater reliability at 5 high-fidelity simulation events. Interrater reliability was calculated using the Pearson correlation coefficient (PCC) and the intraclass correlation coefficient (ICC). RESULTS: The MSCS has 5 categories: airway, breathing, circulation, disability, and extremities or exposure. The scale has 5 levels for each category, from 0 to 4; level increases with complexity, with 0 corresponding to normal or absent. Cases designed to lead to cardiac arrest, regardless of whether or not the trainee has the ability to resuscitate the simulated patient and regardless of the level of each category, are automatically assigned the maximum score. Between 3 and 9 raters used the MSCS to grade the level of complexity of 26 scenarios at the 5 events. The mean MSCS was 10.2 (range 3.0-20.0). Mean PCC and ICC values were both above 0.7 and therefore statistically significant. CONCLUSION: The MSCS for trauma is an innovative scoring system with high interrater reliability.

In-hospital mortality in SARS-CoV-2 stratified by gamma-glutamyl transferase levels.

BACKGROUND: This study investigates in-hospital mortality amongst patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its relation to serum levels of gamma-glutamyl transferase (GGT). METHODS: Patients were stratified according to serum levels of gamma-glutamyl transferase (GGT) (GGT<50 IU/L or GGT≥50 IU/L). RESULTS: A total of 802 participants were considered, amongst whom 486 had GGT<50 IU/L and a mean age of 48.1 (16.5) years, whilst 316 had GGT≥50 IU/L and a mean age of 53.8 (14.7) years. The chief sources of SARS-CoV-2 transmission were contact (366, 45.7%) and community (320, 40%). Most patients with GGT≥50 IU/L had either pneumonia (247, 78.2%) or acute respiratory distress syndrome (ARDS) (85, 26.9%), whilst those with GGT<50 IU/L had hypertension (141, 29%) or diabetes mellitus (DM) (147, 30.2%). Mortality was higher amongst patients with GGT≥50 IU/L (54, 17.1%) than amongst those with GGT<50 IU/L (29, 5.9%). More patients with GGT≥50 required high (83, 27.6%) or low (104, 34.6%) levels of oxygen, whereas most of those with GGT<50 had no requirement of oxygen (306, 71.2%). Multivariable logistic regression analysis indicated that GGT≥50 IU/L (odds ratio [OR]: 2.02, 95% confidence interval [CI]: 1.20-3.45, p=0.009), age (OR: 1.05, 95% CI: 1.03-1.07, p<0.001), hypertension (OR: 2.06, 95% CI: 1.19-3.63, p=0.011), methylprednisolone (OR: 2.96, 95% CI: 1.74-5.01, p<0.001) and fever (OR: 2.03, 95% CI: 1.15-3.68, p=0.016) were significant predictors of all-cause cumulative mortality. A Cox proportional hazards regression model (B = -0.68, SE =0.24, HR =0.51, p = 0.004) showed that patients with GGT<50 IU/L had a 0.51-times lower risk of all-cause cumulative mortality than patients with GGT≥50 IU/L. CONCLUSION: Higher levels of serum GGT were found to be an independent predictor of in-hospital mortality.

Risk Factors for Mortality in Patients with COVID-19: The Kuwait Experience.

OBJECTIVES: To describe the baseline characteristics and to evaluate the risk factors for in-hospital mortality in patients admitted to hospitals with coronavirus disease (COVID-19) in Kuwait. SUBJECTS AND METHODS: This retrospective cohort study analyzed data of patients admitted to two hospitals in Kuwait with COVID-19. The outcome was assessed by using multivariable analysis of factors affecting survival and mortality. RESULTS: In 962 patients, the case fatality ratio was 9.04%. The mean age of nonsurvivors was 63.5 ± 14.8 years, and most deaths occurred in males (80.5%). For the whole sample, the source of transmission was significantly related to mortality and the median duration of in-hospital stay was 15 days (interquartile range: 2-52 days). In patients with high oxygen requirements, the case fatality rate was 96.6%. Multivariable analysis identified age, hypertension, cardiovascular disease (CVD), and dyspnea on presentation as independent risk factors for COVID-19 mortality. CONCLUSIONS: The mortality rate was higher in older patients with comorbidities such as hypertension and CVD. Early recognition of high-risk patients may help to improve care and reduce mortality.

In-hospital mortality in SARS-CoV-2 stratified by serum 25-hydroxy-vitamin D levels: A retrospective study.

This study is done to estimаte in-hоsрitаl mоrtаlity in раtients with severe асute resрirаtоry syndrоme соrоnаvirus 2 (SАRS-СоV-2) strаtified by Vitamin-D (Vit-D) levels. Раtients were strаtified ассоrding tо by serum 25-hydroxy-vitamin D (25(OH)Vit-D) levels intо twо grоuрs, that is, 25(OH)Vit-D less thаn 40 nmol/L аnd 25(OH)Vit-D greаter thаn 40 nmol/L. А tоtаl оf 231 раtients were inсluded. Оf these, 120 (50.2%) оf the раtients hаd 25(OH)Vit-D levels greаter thаn 40 nmol/L. The meаn аge wаs 49 ± 17 yeаrs, аnd 67% оf the раtients were mаles. The mediаn length оf оverаll hоsрitаl stаy wаs 18 [6; 53] dаys. The remаining 119 (49.8%) раtients hаd а 25(OH)Vit-D less thаn 40 nmol/L. Vitamin D levels were seen as deficient in 63% of patients, insufficient in 25% and normal in 12%. Оverаll mоrtаlity wаs 17 раtients (7.1%) but statistically not signifiсаnt among the grоuрs (p = 0.986). The Kарlаn-Meier survivаl аnаlysis shоwed no significance based on an alpha of 0.05, LL = 0.36, df = 1, p = 0.548, indicating Vitamin_D_Levels was not able to adequately predict the hazard of Mortality. In this study, serum 25(OH)Vit-D levels were found have no significance in terms of predicting the in-hоsрitаl mortality in раtients with SАRS-СоV-2.

The Association of Professional Burnout and Turnover Intentions Among Intensive Care Units Physicians: A Cross-Sectional Study.

Intensive Care Units (ICU) workers work in highly stressful conditions that make them prone to professional burnout, which can lead to high turnover rates. This study explores professional burnout levels among ICU workers in Kuwait general governmental hospitals (GGHs), their turnover intentions, and the correlation factors. A cross-sectional self-administered survey study was conducted. Professional burnout level was measured using the Copenhagen Burnout Inventory (CBI), while turnover intention was measured using the Turnover Intention Scale (TIS-6). Data were analyzed using STATA software, and descriptive, correlative, and comparative analyses were performed. Eighty-nine ICU physicians filled out the questionnaire. Most of the participants were males, married, non-Kuwaiti nationals, with 10 to 20 years of experience, and the mean age of respondents was 39.2. The total professional burnout score was high was 54.7 (17.6). There were high total average scores for the personal and work-related domains. Participants who were younger than 35 years of age and graduated before 5 to 10 years had higher levels of professional burnout compared to other groups. More than half of the sample expressed their intention to leave their current job as an ICU physician. However, no association was found between turnover intentions and levels of burnout. High levels of professional burnout of turnover intentions were seen among ICU physicians in Kuwait. Policies should be adopted to reduce and mitigate professional burnout among ICU physicians and increase their retention. Future research should further investigate professional burnout among ICU staff, the associated factors, and its relation to their turnover intention.

In-hospital mortality in SARS-CoV-2 stratified by the use of corticosteroid.

Objective: To investigate COVID-19 related mоrtаlity according to the use of corticosteroid therapy. Design: Retrospective cohort study. Setting: Two tertiary hospitals in Kuwait. Participants: Overall, 962 patients with confirmed SARS-CoV-2 infection, were stratified according to whether they were treated with corticosteroids (dexamethasone or methylprednisolone). The mean age of the patients was 50.2 ± 15.9 years and 344/962 (35.9%) were female. Main outcome measures: In-hospital mortality and cumulative all-cause mortality. Results: Compared to non-corticosteroid therapy patients, corticosteroid therapy patients had a higher prevalence of hypertension, diabetes mellitus, cardiovascular disease, chronic lung disease, and chronic kidney disease; a longer hospital stay (median [IQR]: 17.0 [5.0-57.3] days vs 14.0 [2.0-50.2] days); and a higher in-hospital mortality (51/199 [25.6%] vs 36/763 [4.7%]). Logistic regression analysis showed a higher in-hospital mortality in the corticosteroid group (adjusted odds ratio [aOR]: 4.57, 95% confidence interval [CI]: 2.64-8.02, p < 0.001). Cox proportional hazards regression showed that corticosteroid use was a significant predictor of mortality (hazard ratio [HR]: 3.96, p < 0.001). Conclusions: In-hospital mortality in patients with SARS-CoV-2 on corticosteroid therapy was 4.6 times higher than in those without corticosteroid therapy.

In-hospital Mortality Rates in SARS-CoV-2 Patients Treated with Enoxaparin and Heparin.

OBJECTIVES: This study aimed to investigate in-hospital mortality rates in patients with coronavirus disease (COVID-19) according to enoxaparin and heparin use. METHODS: This retrospective cohort study included 962 patients admitted to two hospitals in Kuwait with a confirmed diagnosis of COVID-19. Cumulative all-cause mortality rate was the primary outcome. RESULTS: A total of 302 patients (males, 196 [64.9%]; mean age, 57.2 ± 14.6 years; mean body mass index, 29.8 ± 6.5 kg/m2) received anticoagulation therapy. Patients receiving anticoagulation treatment tended to have pneumonia (n = 275 [91.1%]) or acute respiratory distress syndrome (n = 106 [35.1%]), and high D-dimer levels (median [interquartile range]: 608 [523;707] ng/mL). The mortality rate in this group was high (n = 63 [20.9%]). Multivariable logistic regression, the Cox proportional hazards, and Kaplan-Meier models revealed that the use of therapeutic anticoagulation agents affected the risk of all-cause cumulative mortality. CONCLUSION: Age, hypertension, pneumonia, therapeutic anticoagulation, and methylprednisolone use were found to be strong predictors of in-hospital mortality. In elderly hypertensive COVID-19 patients on therapeutic anticoagulation were found to have 2.3 times higher risk of in-hospital mortality. All cause in-hospital mortality rate in the therapeutic anticoagulation group was up to 21%.

In-hospital mortality in SARS-CoV-2 stratified by sex diffrences: A retrospective cross-sectional cohort study.

Background: The aim of this study was to determine in-hospital mortality in patients presenting with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) and to evaluate for any differences in outcome according to sex differences. Methods: Patients with SRS-CoV-2 infection were recruited into this retrospective cohort study between February 26 and September 8, 2020 and strаtified ассоrding tо the sex differences. Results: In tоtаl оf 3360 раtients (meаn аge 44 ± 17 years) were included, of whom 2221 (66%) were mаle. The average length of hospitalization was 13 days (range: 2-31 days). During hospitalization and follow-up 176 patients (5.24%) died. In-hospital mortality rates were significantly different according to gender (p=<0.001). Specifically, male gender was associated with significantly greater mortality when compared to female gender with results significant at an alpha of 0.05, LL = 28.67, df = 1, p = 0.001, suggesting that gender could reliably determine mortality rates. The coefficient for the males was significant, B = 1.02, SE = 0.21, HR = 2.78, p < 0.001, indicating that an observation in the male category will have a hazard 2.78 times greater than that in the female category. Multivariate logistic regression confirmed male patients admitted with SARS-CoV-2had higher сumulаtive аll-саuse in-hоsрitаl mоrtаlity (6.8% vs. 2.3%; аdjusted оdds rаtiо (аОR), 2.80; 95% (СI): [1.61-5.03]; р < 0.001). Conclusions: Male gender was an independent predictor of in-hospital mortality in this study. The mortality rate among male SARS-CoV-2 patients was 2.8 times higher when compared with females.

Neutrophil to lymphocyte ratio and in-hospital mortality among patients with SARS-CoV-2: A retrospective study.

The goal of this study was to investigate in-hospital mortality in patients suffering from acute respiratory syndrome coronavirus 2 (SARS-CoV-2) relative to the neutrophil to lymphocyte ratio (NLR) and to determine if there are gender disparities in outcome. Between February 26 and September 8, 2020, patients having SARS-CoV-2 infection were enrolled in this retrospective cohort research, which was categorized by NLR levels ≥9 and < 9. In total, 6893 patients were involved included of whom6591 had NLR <9, and 302 had NLR ≥9. The age of most of the patients in the NLR<9 group was 50 years, on the other hand, the age of most of the NLR ≥9 group patients was between 50 and 70 years. The majority of patients in both groups were male 2211 (66.1%). The ICU admission time and mortality rate for the patients with NLR ≥9 was significantly higher compared to patients with NLR <9. Logistic regression's outcome indicated that NLR ≥9 (odds ratio (OR), 24.9; 95% confidence interval (CI): 15.5-40.0; p < 0.001), male sex (OR, 3.5; 95% CI: 2.0-5.9; p < 0.001) and haemoglobin (HB) (OR, 0.95; 95% CI; 0.94-0.96; p < 0.001) predicted in-hospital mortality significantly. Additionally, Cox proportional hazards analysis (B = 4.04, SE = 0.18, HR = 56.89, p < 0.001) and Kaplan-Meier survival probability plots also indicated that NLR>9 had a significant effect on mortality. NLR ≥9 is an independent predictor of mortality(in-hospital) among SARS-CoV-2 patients.

In-hospital mortality in SARS-CoV-2 stratified by hemoglobin levels: A retrospective study.

This study is to estimate in-hospital mortality in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients stratified by hemoglobin (Hb) level. Patients were stratified according to hemoglobin level into two groups, that is, Hb <100 g/L and Hb >100 g/L. A total of 6931 patients were included. Of these, 6377 (92%) patients had hemoglobin levels >100 g/L. The mean age was 44 ± 17 years, and 66% of the patients were males. The median length of overall hospital stay was 13 days [2; 31]. The remaining 554 (8%) patients had a hemoglobin level <100 g/L. Overall mortality was 176 patients (2.54%) but was significantly higher in the group with hemoglobin levels <100 g/L (124, 22.4%) than in the group with hemoglobin levels >100 g/L (52, 0.82%). Risk factors associated with increased mortality were determined by multivariate analysis. The Kaplan-Meier survival analysis showed hemoglobin as a predictor of mortality. Cox proportional hazards regression coefficients for hemoglobin for the HB ≤ 100 category of hemoglobin were significant, B = 2.79, SE = 0.17, and HR = 16.34, p < 0.001. Multivariate logistic regression showed Hb < 100 g/L had a higher cumulative all-cause in-hospital mortality (22.4% vs. 0.8%; adjusted odds ratio [aOR], 0.33; 95% [CI]: [0.20-0.55]; p < 0.001). In this study, hemoglobin levels <100 g/L were found to be an independent predictor of in-hospital mortality.

Ferritin level: A predictor of severity and mortality in hospitalized COVID-19 patients.

INTRODUCTION: This study aims to investigate in-hоsрitаl mоrtаlity in severe асute resрirаtоry syndrоme соrоnаvirus 2 Ñ€Ð°tients strаtified by serum ferritin levels. METHODS: Patients were stratified based on ferritin levels (ferritin levels ≤ 1000 or >1000). RESULTS: Approximately 89% (118) of the patients with ferritin levels > 1000 had pneumonia, and 51% (67) had hypertension. Fever (97, 73.5%) and shortness of breath (80, 61%) were two major symptoms among the patients in this group. Logistic regression analysis indicated that ferritin level (odds ratio [OR] = 0.36, 95% confidence interval [CI] = 0.21-0.62; p < .001), male sex (OR = 2.63, 95% CI = 1.43-5.06; p = .003), hypertension (OR = 4.16, 95% CI = 2.42-7.36; p < .001) and pneumonia (OR = 8.48, 95% CI = 3.02-35.45; p < .001) had significance in predicting in-hospital mortality. Additionally, the Cox proportional hazards analysis and Kaplan-Meier survival probability plot showed a higher mortality rate among patients with ferritin levels > 1000. CONCLUSION: In this study, higher levels of serum ferritin were found to be an independent predictor of in-hоsрitаl mоrtаlity.

Total Gastric Necrosis Due to Mucormycosis: A Rare Case of Gastric Perforation.

BACKGROUND Spontaneous gastric perforation is usually a complication of peptic ulcer disease, or a postoperative complication resulting from gastric torsion. Mucormycosis (or zygomycosis) is an uncommon opportunistic fungal infection that is usually seen in immunocompromised patients and is associated with significant morbidity and mortality. This report is of a rare case of spontaneous gastric perforation due to mucormycosis infection. CASE REPORT A 52-year-old woman, with a past medical history of heroin abuse, diabetes mellitus, hypertension, and chronic kidney disease treated by dialysis, presented to the emergency department with cellulitis of the arms. Following hospital admission, her medical condition deteriorated, and she developed septic shock and multiorgan failure, requiring transfer to the intensive care unit (ICU), where she was diagnosed with a perforated hollow viscus as the cause. Surgical exploration showed that the mucosa of the stomach was necrotic and perforated, but the remaining bowel appeared normal. Total gastrectomy was performed, and a jejunostomy feeding tube was inserted. Histopathology of the gastric tissue confirmed infection with mucormycosis. The patient was treated with adjunctive liposomal amphotericin B, her condition improved, and she was extubated on postoperative day 2. However, the patient died on postoperative day 21 due to sepsis and multiorgan failure. CONCLUSIONS Mucormycosis is an opportunistic angioinvasive fungal infection, and gastric perforation is a rare clinical presentation. However, knowledge of the association between gastric necrosis and perforation and mucormycosis infection might lead to early diagnosis and treatment and reduce patient morbidity and mortality.

Management of hypertensive patients in primary health care setting, auditing the practice.

OBJECTIVE: To audit the medical care provided to hypertensive patients in a health care center in Riyadh, Kingdom of Saudi Arabia (KSA) and determine the efficient control of hypertension. METHODS: We carried out this cross-sectional study on all patients who visited the Health Care Specialty Center of King Abdul-Aziz Medical City, Riyadh, KSA for hypertension follow-up during the study period from October to December 2004. A representative sample of patients was allocated randomly using simple randomization method. All patient's records were reviewed for proper recording in a designed form. RESULTS: Out of the 242 records we reviewed, 201 were included in the study. The patients' mean age was 58.3 +/- 12.5 years. All were Saudis and 78.6% were females. Most of them (84.3%) received their management at primary care level only. Age, gender, presence of diabetes, level of medical care, blood glucose, lipid levels and drugs used for management of hypertension were sufficiently recorded. Smoking history, body mass index and family history of ischemic heart disease were poorly recorded. Quarter of the hypertensive patients was sufficiently controlled. The factors associated with poor blood pressure (BP) control were advanced age (p=0.008) and presence of diabetes, [odds ratio (95% CI)=2.98 (1.47-6.08)]. CONCLUSION: The study reflects the deficiencies in BP control and physicians practice. Introducing a checklist or electronic medical records may help the improvement of care. Frequent auditing is recommended to ensure the required development.

Factors associated with poor asthma control in the outpatient clinic setting.

BACKGROUND/OBJECTIVES: The goal of the study was to assess asthma control using asthma control test (ACT) and to explore the factors that effects asthma control among participants with bronchial asthma in the outpatient clinic setting. METHODS: This cross-sectional descriptive study was conducted in the outpatient primary care clinic at King Abdulaziz Medical City in Riyadh. Adult patients who were diagnosed with bronchial asthma by their primary treating physician were recruited over a 6-month period. Patients completed the ACT and questionnaires, which identified factors that affect asthma control. RESULTS: Four hundred asthmatic patients (n = 400) were enrolled, and 70% of these patients were women. Fifty-four percent of patients inappropriately used the inhaler device. The estimated prevalence of uncontrolled asthma at the time of the study was 39.8%. Inappropriate device use by the patient was more frequently associated with uncontrolled asthma (P-value = 0.001). Active smoking (P-value = 0.007), passive smoking (P-value = 0.019), unsealed mattress (P-value = 0.030), and workplace triggers (P-value = 0.036) were also associated with uncontrolled asthma. However, the extent of asthma control did not appear to be related to the existence of regular follow-ups, bedroom carpets, outpatient clinic visits, age, body mass index (BMI), or duration of asthma. CONCLUSIONS: The present study identified a high prevalence of uncontrolled asthma in the primary outpatient clinic setting and common risk factors that may contribute to poor asthma control.
