ABSTRACT
Background: Predicting the severity of COVID-19 infection in advance is the key to success of its treatment outcome. Various scoring systems are used to detect the severity of this disease but this study targets three simple scoring systems based on the vital parameters and basic routine laboratory tests. Aims and Objectives: The aim of the study was to assess the predictability of three scoring systems (Quick sequential organ failure assessment [q SOFA], CURB-65, and Early Warning scoring system) for disease severity at presentation in a rural-based tertiary care center. Materials and Methods: An observational, descriptive, retrospective, and cross-sectional study was conducted at Diamond Harbour Government Medical College Covid Hospital from January 2021 to January 2022 to assess the predictability of q SOFA, CURB-65, and Early Warning scoring system for disease severity at presentation. Results: The total number of participants was 561 among total admitted 1367 patients. A short descriptive analysis obtained from the variables to analyze the scorings howed among total sample collected, 57% were male and 43% were female. In this study, 87% of patients were survived and the rest 13% succumbed (death). There is no statistically significant difference in mortality between both genders. Age, pulse rate, and respiratory rate have a significant correlation with the outcome and altered sensorium is also highly associated with mortality. The accuracy was also found to be little higher for National Early Warning score (NEWS) score than CURB-65 scoring and q SOFA scoring (0.919, 0.914 and 0.907). Although all the scoring systems have high sensitivity (>90%) (CURB 65: Most sensitive [0.99]), the specificities of all three scoring systems are below 50%. Among these three-scoring systems, NEWS showed the highest specificity (0.492) than q SOFA (0.423) and CURB 65 (0.394). Conclusion: We suggest NEWS score and CURB-65 as a better predictor for in-hospital mortality in COVID-19 patients as it is significantly sensitive and reasonably specific. It can be recommended in less equipped hospitals where only basic laboratory facilities are available. qSOFA can be utilized where no laboratory facility is available like in safe home and isolation centers.
ABSTRACT
Objective To explore the value of thromboelastography (TEG) in patients with multiple trauma in emergency department. Methods The clinical data of 302 patients with multiple trauma hospitalized in the emergency department of Gansu Provincial People's Hospital from August 2015 to December 2018 were retrospectively analyzed. The general clinical data of the patients were collected. The patients were divided into three groups according to injury severity score (ISS): mild injury group (ISS ≤ 16), serious injury group (ISS 17-25), and severe injury group (ISS > 25). The results of vital signs, routine coagulation test, blood routine, blood biochemistry, and arterial blood gas analysis were recorded, and the National early warning score (NEWS) was calculated. TEG parameters were analyzed. Pearson correlation analysis and linear regression analysis were used to analyze the correlation between TEG indicators and NEWS score. Receiver operator characteristic (ROC) curve was plotted to analyze the diagnostic efficacy of TEG indicators for disseminated intravascular coagulation (DIC) in patients with severe injury. Results 299 patients were enrolled in the final analysis, including 92 patients in the mild injury group, 109 in the serious injury group and 98 in the severe injury group. With the increase in trauma severity, the NEWS score and TEG indicators including coagulation reaction time (R value) and blood clot generation time (K value) were gradually increased [NEWS score in mild, serious, and severe injury group was 3.46±0.89, 5.85±0.62, 9.75±1.76, R value (minutes) was 5.8±2.8, 7.8±2.6, 11.7±3.0, and K value (minutes) was 2.4±1.0, 4.2±1.4, 5.5±2.9, respectively], and blood clot generation rate (α angle), maximum width value (MA value) and coagulation index (CI) were gradually decreased [α angle (°) in mild, serious, and severe injury group was 66.9±13.5, 55.7±22.9, 46.8±26.3, MA value (mm) was 51.8±9.7, 48.1±17.0, 38.5±15.2, and CI was 2.0±3.6, -2.8±3.5, -6.7±2.9, respectively], the differences were statistically significant among the groups (all P < 0.05). Pearson correlation analysis showed that the NEWS score was positively correlated with R and K values (r value was 0.463,0.588, respectively, both P < 0.01), and it was negatively correlated with α angle, MA value and CI (r value was -0.622, -0.689, -0.902, respectively, all P < 0.01). Linear correlation analysis showed that for every 1 minute increase in R value, NEWS score increased by 0.882 [95% confidence interval (95%CI) = 0.691 to 1.073]; for every 1 minute increase in K value, NEWS score increased by 0.484 (95%CI = 0.408 to 0.559); for every 1°increase in α angle, NEWS score decreased by 2.910 (95%CI = -3.325 to -2.494); for every 1 mm increase in MA value, NEWS score decreased by 2.223 (95%CI = -2.488 to -1.958); for every 1 increase in CI, NEWS score decreased by 1.292 (95%CI =-1.362 to -1.221). The R and K values in DIC patients (n = 37) of the severe injury group were significantly higher than those in non-DIC patients [n = 61; R value (minutes): 15.8±5.6 vs. 9.8±2.6, K value (minutes): 7.6±3.1 vs. 4.3±2.2], and α angle, MA value and CI were significantly lowered [α angle (°): 48.7±19.8 vs. 59.6±26.2, MA value (mm):37.5±19.2 vs. 49.2±18.6, CI: -8.5±3.4 vs. -5.2±3.1], the differences were statistically significant between the two groups (all P < 0.05). ROC curve analysis showed that the area under ROC curve (AUC) of the R and K values for predicting DIC was 0.999 and 0.958, respectively. When the optimal cut-off value of R value was 12.3 minutes, the sensitivity and specificity were 97.5% and 100%; when the optimal cut-off value of K value was 5.7 minutes, the sensitivity and specificity were 92.5% and 82.0%. The AUC of α angle, MA value and CI were 0.084, 0.060 and 0.114, which had no predictive value. Conclusions TEG indicators have clinical value on predicting the severity of illness in patients with multiple trauma. The changes in R and K values are effective indicators to judge the risk of DIC in patients with severe multiple trauma.
ABSTRACT
Objective To evaluate national early warning score (NEWS), quick sequential organ failure assessment (qSOFA) and systemic inflammatory response syndrome (SIRS) score in predicting of the severity in patients with heat stroke. Methods NEWS, qSOFA and SIRS score of patients with heat stroke in the Central Hospital of Shenyang Medical College from July 31st to August 5th, 2018 were analyzed retrospectively. Results The age of patients in death group was older than that in survival group significantly (P < 0.05). The scores of NEWS, qSOFA and SIRS of patients in death group was higher than that in survival group significantly (P < 0.05). The relativity study showed a positive correlation between the score of NEWS, qSOFA and SIRS. The AUC of NEWS, qSOFA, and SIRS were 0.884, 0.804 and 0.627 respectively for the predicting of admission into Intensive Care Unit (ICU). The AUC of NEWS, qSOFA and SIRS were 0.972, 0.898, and 0.673 respectively for the predicting death. Conclusions Both NEWS and qSOFA can be used to predicting the admission into ICU and death. The specificity of NEWS is better in predicting of admission into ICU and death, and qSOFA is better in the sensitivity of predicting death.
ABSTRACT
Objective To explore the value of national early warning score (NEWS) to assess the severity and prognosis of acute pancreatitis. Methods The clinical data of 110 patients with acute pancreatitis from March to November 2016 were retrospectively analyzed. The NWES, Rason score and acute physiology and chronic health evaluation Ⅱ score (APACHE Ⅱ score) were calculated respectively. Correlation analysis was carried out with Pearson linear regression, and the receiver operating characteristic (ROC) curve was analyzed.

The NEWS scores of mild cases, moderately severe cases and severe cases were (1.92 ± 1.86) scores, (4.25 ± 1.58) scores, and (5.94 ± 2.43) scores, and there was statistical difference (P<0.05). NEWS was positively correlated with Rason score and APACHE Ⅱ score (r = 0.653 and 0.794, P<0.05). The area under curve (AUC) of NEWS predicting moderately severe and severe cases was 0.866. The cut off was 3 scores, and the sensitivity and specificity were 77.8％and 79.5％;the AUC of NEWS predicting death was 0.872. The cut off was 5 scores, and the sensitivity and specificity were 71.4％ and 89.3％. Conclusions NEWS score can early predict the severity and prognosis of acute pancreatitis.
ABSTRACT
Objective To investigate the prognostic value of National Early Warning Scores (NEWS) combined with arterial lactate level in elderly patients with critical illness in emergency department.Methods A total of 413 elderly patients with critical illness randomly (random number) selected from resuscitation room in emergency department from September 2013 to July 2015 were enrolled in this study.NEWS system was employed to determine the patients' condition.Arterial lactate level was detected.The patients were followed for the 30-day death by telephone calls and patients were divided into survival group and death group.Multivariate logistic regression analysis and receiver operating characteristic curve (ROC) were used to evaluate the prognostic values of NEWS score,arterial lactate level,and NEWS score combined with arterial lactate level in patients without survival.Results There were significant differences in NEWS score and arterial lactate level between the death group and the survival group.The results of multiple factor regression showed that NEWS score,arterial lactate level,and NEWS score combined with arterial lactate level were all independent predictors of 30-day death (P ＜ 0.05,OR ＞ 1).The AUCs of the three evaluation modalities were 0.721,0.746 and 0.762,respectively.There was a significant difference in the area under the ROC curve between NEWS score and NEWS score combined with arterial lactate level.The optimal cut-off point of NEWS score was 7,and arterial lactate level was 2.7 mmol/L.Conclusions NEWS score,arterial lactate level,and NEWS score combined with arterial lactate level were independent predictors of 30-day death in elderly patients with critical illness in emergency department.They all had some predictive value,and NEWS score combined with arterial lactate level had higher capability to predict 30-day death in elderly patients with critical illness in emergency department than NEWS score alone.
ABSTRACT
Objective To analyze the comparation of national early warning score (NEWS), rapid emergency medicine score (REMS) and acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score in predicting prognosis of critically ill patients in emergency department (ED). Methods A retrospective study was conducted. Critically ill patients, aged > 16 years, hospitalized > 24 hours, and admitted to the ED of Nanhua Hospital Affiliated to South China University from January 2016 to June 2017 were enrolled. NEWS, REMS and APACHE Ⅱ score were calculated based on the worst value of each index within 24 hours after emergency admission. The primary endpoint was 28-day mortality. The relationship between the three scoring systems and the prognosis of patients was analyzed. The predictive value of three scoring systems for the prognosis of critically ill patients in ED was analyzed by receiver operating characteristic curve (ROC). Results A total of 119 emergency severe patients were enrolled in the study, and the 28-day mortality was 21.0%. The scores of NEWS, REMS and APACHE Ⅱ in the death group were significantly higher than those in the survival group (NEWS score: 9.40±3.19 vs. 5.72±2.35, REMS score: 12.64±4.46 vs. 7.97±3.28, APACHE Ⅱscore: 26.64±6.92 vs. 16.19±5.48, all P < 0.01). With the increase of NEWS, REMS and APACHE Ⅱ score, the 28-day mortality of patients gradually increased [28-day mortality of NEWS < 5, 5-6, ≥ 7 was 3.03% (1/34), 13.33% (4/34), 64.25% (20/51); 28-day mortality of REMS < 12, 12-16, ≥ 17 was 10.99% (10/91), 50.00% (11/22), 66.67% (4/6); 28-day mortality of APACHE Ⅱ < 15, 15-24, ≥ 25 was 2.33% (1/43), 15.09% (8/59), 69.57% (16/23), respectively, all P < 0.01]. The ROC curve analysis showed that the areas under the ROC curve (AUC)of NEWS, REMS and APACHE Ⅱ score for predicting the prognosis of emergency critically ill patients were 0.830 [95% confidence interval (95%CI) = 0.737-0.923], 0.782 (95%CI = 0.671-0.892) and 0.878 (95%CI = 0.800-0.956), respectively (all P = 0.000), and the accuracy of prediction was 57.4%, 48.6%, 65.4%, respectively. Conclusions The scores of NEWS, REMS and APACHE Ⅱ were useful in predicting prognosis of critically ill patients, with the highest accuracy of APACHE Ⅱ forecast, followed by NEWS, and the lowest of REMS. After comprehensive consideration of cost-effectiveness, NEWS is more reliable in ED.
ABSTRACT
Objective To verify the validity and feasibility of national early warning score (NEWS) in evaluation of death risk in elderly patients with critical illness,in order to find out which scoring method is more suitable for elderly critical illness patients.Methods A prospective case-control study was conducted.The critical illness patients aged over 60 years old with the length of hospital stay over 24 hours,and admitted to Department of Emergency of Qingdao Municipal Hospital from January to December 2015 were enrolled.The clinical data including in emergency and the actual outcome of patients were collected,and the patients were divided into death group and survival group according to 30-day outcome.Patients in the two groups were assessed by using NEWS and risk classification according to the first results of vital signs monitoring.Multivariate logistic regression model was used to analyze the relationship between the NEWS classification and the risk of death in elderly critical ill patients.Results 1 950 emergency elderly patients with critical illness were enrolled,with 78 cases (4.0％) dead within 30 days and 1 872 survived (96.0％).Compared with the survival group,patients in death group were older (years:79.8 ± 10.8 vs.75.3 ± 8.9,t =4.335,P ＜0.001),and had higher acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score (22.9± 4.6 vs.18.2 ± 4.8,t =8.487,P ＜ 0.001),lower Glasgow coma scale (GCS) score (12.2 ± 4.5 vs.13.4 ± 5.2,t =-2.007,P =0.045),higher incidence of respiratory system diseases (29.5％ vs.17.9％,x 2 =12.742,P =0.013),higher NEWS score (11.2 ± 5.5 vs.3.9 ± 2.7,t =22.063,P ＜ 0.001),as well as higher proportion of patients with NEWS classification of high risk and very high risk (65.4％ vs.15.8％,x 2 =263.125,P ＜ 0.001).With the increase of NEWS risk classification,mortality rate was also increased,and the mortality rate in the patients with low,medium,high and very high risk were 0.81％ (9/1 108),3.63％ (18/496),5.83％ (13/223),30.89％ (38/123),respectively,with statistically significant difference (x 2 =179.741,P ＜ 0.001).It was showed by logistic regression analysis that the NEWS score of elderly patients with critical illness were positively correlated with 30-day death.The 30-day death risk of patients with middle risk,high risk and very high risk was 4.600,9.052 and 54.598 folds of the patients with low risk respectively.Conclusion NEWS score can be used to assess the risk of death in emergency elderly patients with critical illness.NEWS risk classification can quantify and classify the risk of death in the elderly patients with critical illness.
