Glasgow coma scale compared to other trauma scores in discriminating in-hospital mortality of traumatic brain injury patients admitted to urban Indian hospitals: A multicentre prospective cohort study

BackgroundGlasgow Coma Scale (GCS) is one of the most commonly used trauma scores and is a good predictor of outcome in traumatic brain injury (TBI) patients. There are other more complex scores with additional physiological parameters. Whether they discriminate better than GCS in predicting mortality in TBI patients is debatable. The aim of this study was to compare the discrimination of GCS with that of MGAP, GAP, RTS and KTS for 24-hour and 30-day in-hospital mortality in adult TBI patients, in a resource limited LMIC setting. MethodWe analysed data from the multicentre, observational trauma cohort Towards Improved Trauma Care Outcome (TITCO) in India. We included all patients 18 years or older, admitted from the emergency department with TBI. The Area Under the Receiver Operating Characteristic (AUROC) curve was used to quantify and compare the discrimination of all scores: GCS; Revised Trauma Score (RTS); mechanism, GCS, age, systolic blood pressure (MGAP); GCS, age, systolic blood pressure (GAP) and Kampala Trauma Score (KTS) in the prediction of 24-hour and 30-day in-hospital mortality. ResultsA total of 3306 TBI patients were included in this study. The majority were within the GCS range 3-8. The commonest mechanism of injury was road traffic injuries [1907(58.0%)]. In-hospital mortality was 27.2% (899). There was no significant difference in discrimination in 24-hour in-hospital mortality when comparing GCS with MGAP and GAP. While GCS performed better than KTS, RTS performed better than GCS. For 30-day in-hospital mortality, GCS discriminated significantly better compared with KTS, but there was no significant difference when compared to MGAP and RTS. GAP discriminated significantly better when compared with GCS. ConclusionThis study shows that the discrimination of GCS is comparable to that of more complex trauma scores in predicting 24-hour and 30-day in-hospital mortality in adult TBI patients in a resource limited LMIC setting.

A cohort study of differences in trauma outcomes between females and males at four Indian Urban Trauma Centers

Background Studies from high income countries suggest improved survival for females as compared to males following trauma. However, data regarding differences in trauma outcomes between females and males is severely lacking from low- and middle-income countries. The objective of this study was to determine the association between sex and clinical outcomes amongst Indian trauma patients using the Australia-India Trauma Systems Collaboration database.Methods A prospective multicentre cohort study was performed across four urban public hospitals in India April 2016 through February 2018. Bivariate analyses compared admission physiological parameters and mechanism of injury. Logistic regression assessed association of sex with the primary outcomes of 30-day and 24-hour in-hospital mortality. Secondary outcomes included ICU admission, ICU length of stay, ventilator requirement, and time on a ventilator.Results Of 8,605 patients, 1,574 (18.3%) were females. The most common mechanism of injury was falls for females (52.0%) and road traffic injury for males (49.5%). On unadjusted analysis, there was no difference in 30-day in-hospital mortality between females (11.6%) and males (12.6%, p = 0.323). However, females demonstrated a lower mortality at 24-hours (1.1% vs males 2.1%, p = 0.011) on unadjusted analysis. Females were also less likely to require a ventilator (17.3% vs 21.0% males, p = 0.001) or ICU admission (34.4% vs 37.5%, p = 0.028). Stratification by age or by ISS demonstrated no difference in 30-day in-hospital mortality for males vs females across age and ISS categories. On multivariable regression analysis, sex was not associated significantly with 30-day or 24-hour in-hospital mortality.Conclusion This study did not demonstrate a significant difference in the 30-day trauma mortality or 24-hour trauma mortality between female and male trauma patients in India on adjusted analyses. A more granular data is needed to understand the interplay of injury severity, immediate post-traumatic hormonal and immunological alterations, and the impact of gender-based disparities in acute care settings.

Associations of On-arrival Vital Signs with 24-hour In-hospital Mortality in Adult Trauma Patients Admitted to Four Public University Hospitals in Urban India: A Prospective Multi-Centre Cohort Study.

In India, more than a million people die annually due to injuries. Identifying the patients at risk of early mortality (within 24 hour of hospital arrival) is essential for triage. A bilateral Government Australia-India Trauma System Collaboration generated a trauma registry in the context of India, which yielded a cohort of trauma patients for systematic observation and interventions. The aim of this study was to determine the independent association of on-arrival vital signs and Glasgow Coma Score (GCS) with 24-hour mortality among adult trauma patients admitted at four university public hospitals in urban India. We performed an analysis of a prospective multicentre observational study of trauma patients across four urban public university hospitals in India, between April 2016 and February 2018. The primary outcome was 24-hour in-hospital mortality. We used logistic regression to determine mutually independent associations of the vital signs and GCS with 24-hour mortality. A total of 7497 adult patients (18 years and above) were included. The 24-hour mortality was 1.9%. In univariable logistic regression, Glasgow Coma Score (GCS) and the vital signs systolic blood pressure (SBP), heart rate (HR), respiratory rate (RR) and peripheral capillary oxygen saturation (SpO2) had statistically significant associations with 24-hour mortality. These relationships held in multivariable analysis with hypotension (SBP<90mm Hg), tachycardia (HR>100bpm) and bradycardia (HR<60bpm), hypoxia (SpO2<90%), Tachypnoea (RR>20brpm) and severe (3-8) and moderate (9-12) GCS having strong association with 24-hour mortality. Notably, the patients with missing values for SBP, HR and RR also demonstrated higher odds of 24-hour mortality. The Injury Severity Scores (ISS) did not corelate with 24-hour mortality. The routinely measured GCS and vital signs including SBP, HR, SpO2 and RR are independently associated with 24-hour in-hospital mortality in the context of university hospitals of urban India. These easily measured parameters in the emergency setting may help improve decision-making and guide further management in the trauma victims. A poor short-term prognosis was also observed in patients in whom these physiological variables were not recorded.

Blood transfusion: In the air tonight?

The use of prehospital blood transfusion (PBT) in air medical transport has become more widespread. However, the effect of PBT remains unknown. The aim of this study was to examine the impact of PBT on 24-hour and overall in-hospital mortality. This is a retrospective cohort study of all trauma patients carried by air medical transport from the scene to a Level I trauma center from 2007 to 2013. We excluded patients who died on the helipad or in the emergency department. Primary outcomes measured were 24-hour and overall in-hospital mortality. Multivariable logistic regressions using all available patient data or the propensity score (for receiving PBT)-matched patient data were performed to study the effect of PBT on these outcomes. Of the 5,581 patients included in the study, 231 (4%) received PBT. Multivariable regression analyses did not show evidence of PBT effect on 24-hour in-hospital mortality (odds ratio [OR], 1.22; 95% confidence interval [CI], 0.61-2.44) and on overall in-hospital mortality (OR, 1.20; 95% CI, 0.55-1.79). In addition, using 1:1 propensity score-matched data, the analysis did not show evidence of PBT effect on 24-hour in-hospital mortality (OR, 1.04; 95% CI, 0.54-1.98) and on overall in-hospital mortality (OR, 1.05; 95% CI, 0.56-1.96). Factors associated with increased 24-hour mortality were advanced age, penetrating injury, increased blood transfusion requirement in the first 24 hours, and decreased Glasgow Coma Scale (GCS) score (p < 0.05). These factors were also associated with overall mortality, in addition to increased Injury Severity Score (ISS) (p < 0.05). This is the largest study to date of trauma patients who received PBT and were transported from the scene by air medical transport. Our results show no effect of PBT on 24-hour and overall in-hospital mortality. Previous studies also suggest no benefit of PBT, which is counterintuitive to damage-control resuscitation. Prospective data on PBT are needed to assess risk, cost, and benefit. Therapeutic study, level III.
