Changing to AIS 2005 and agreement of injury severity scores in a trauma registry with scores based on manual chart review

Traumatic diaphragmatic injuries are uncommon events but are associated with a high mortality. We hypothesize that injury pattern has changed over time with increasing prevalence of blunt injuries. A retrospective chart review was performed of 124 patients who sustained traumatic diaphragmatic injuries over the 20-year period between January 1,1986 and December 31, 2005. Penetrating trauma accounted for 65 per cent (80/124) of all diaphragm injuries, and blunt trauma for 35 per cent (44/124). Mean Injury Severity Scores of 19 ± 9 and 34 ± 13 were observed for the penetrating and blunt trauma groups, respectively ( P = 0.001). Blunt traumatic diaphragm injuries increased from 13 per cent in the first 10-year period to 66 per cent in the second 10-year period ( P = 0.001). The overall mortality was 9 per cent (11/124) with 10 deaths resulting from blunt trauma and one resulting from penetrating trauma ( P < 0.001). The mortality rate increased from 3 to 17 per cent over the two decades ( P = 0.007). Our data suggests that over the last 20 years, the increase in mortality associated with traumatic diaphragmatic injury is primarily related to an increase in the proportion of patients with blunt trauma as a cause of their diaphragmatic injury and associated injuries.

Conversion Tool

Although the Abbreviated Injury Scale (AIS) is the most widely used severity scoring system for traumatic injuries, hospitals are required to document and bill based on the International Classification of Diseases (ICD). An expert panel recently developed a map between ICD-9-CM and ICD-10-CM to AIS 2005 Update 2008. This study aimed to validate the recently developed map using a large trauma registry. The map demonstrated moderate to substantial agreement for maximum AIS (MAIS) scores per body region based on expert chart review versus map-derived values (range: 44%–86%). Injury Severity Scores (ISSs) calculated from expert coders versus map-derived values were also compared and demonstrated moderate agreement (ICD-9-CM: 48%, ICD-10-CM: 54%). Although not a perfect conversion tool, the new ICD-AIS map provides a systematic method to assign injury severity for datasets with only ICD-9-CM and ICD-10-CM codes available and can be used for future injury-related research and data analysis.

Severity Scores

In the past, injuries to the adrenal glands due to blunt trauma were considered rare, and were reported to be associated with high Injury Severity Scores (ISSs) and high mortality. Recent reports have reported a much high incidence associated with lower ISS and lower mortality. The purpose of this study was to assess the incidence of adrenal gland injuries due to blunt trauma in a large state trauma registry and determine whether these injuries are associated with a higher ISS and increased risk for mortality. A retrospective review was performed on the New York State Trauma Registry comparing blunt injured adults with adrenal injuries to those who did not. Concurrent organ injuries, ISS, and inhospital mortality were compared. Three hundred thirty-nine patients with adrenal gland injuries were identified. Concurrent liver and kidney injuries were more prevalent in the adrenal injured group, and concurrent injuries to the small and large intestine and spleen were more prevalent in the nonadrenal injured group. There was no difference in ISS or mortality between the adrenal injured and nonadrenal injured populations. The results of this study are consistent with recent smaller studies which identified incidence rates which were higher than previously reported and that ISS and mortality risk were unchanged by the presence of blunt adrenal gland injuries. Adrenal gland injuries due to blunt trauma are not uncommon, with an incidence rate of 0.61 per cent. Adrenal gland injuries are not associated with higher ISS or an increased risk of mortality.

AbstractBackgroundInjury and death involving all-terrain vehicles (ATV) has been reported in a number of Canadian provinces. The objective of this study is to describe the frequency, nature, severity, population affected, immediate health costs, efficacy of related legislation, and helmet use in ATV related injuries and deaths in Newfoundland and Labrador (NL).MethodsA retrospective review of injured or deceased ATV riders of all ages entered in the Newfoundland and Labrador Trauma Registry from 2003 to 2013 was conducted. Variables studied included demographics, injury type and severity, use of helmets, admission/discharge dates, and referring/receiving institution. Data was also obtained from the Newfoundland and Labrador Center for Health Information (NLCHI) and included all in-hospital deaths and hospitalizations due to ATVs between 1995 and 2013.ResultsThere were a total of 298 patients registered in the trauma registry, resulting in 2759 admission days, nine deaths, and a total estimated immediate healthcare system cost in excess of $1.6 million. More males (N=253, 84.9%) than females (N=45, 15.1%) were injured in ATV related incidents, t(20)=7.12, p<.0001. Head and thorax injuries were the most serious. 38.6% of patients were confirmed to be wearing helmets. Mean injury severity scores are as follows: head injury (M=11, SD=9.51), thorax (M=10, SD=8.3), abdominal/pelvis (M=9, SD=7.62), upper extremity (M=9, SD=8.53), other injuries (M=9, SD=10.56) lower extremity (M=8, SD=8.34), and spine (M=8, SD=6.52).ConclusionsThis study describes ATV related injuries and deaths in NL. Information from this study may guide physician practice, public education, and future legislation.

The Impact

Abstract Background Treatment of blunt splenic injury has changed over the past decades. Nonoperative management (NOM) is the treatment of choice. Adequate patient selection is a prerequisite for successful NOM. Impaired mental status is considered as a relative contra indication for NOM. However, the impact of altered consciousness in well-equipped trauma institutes is unclear. We hypothesized that impaired mental status does not affect outcome in patients with splenic trauma. Methods Our prospectively composed trauma database was used and adult patients with blunt splenic injury were included during a 14-year time period. Treatment guidelines remained unaltered over time. Patients were grouped based on the presence (Group GCS: < 14) or absence (Group GCS: 14–15) of impaired mental status. Outcome was compared. Results A total of 161 patients were included, of whom 82 were selected for NOM. 36% of patients had a GCS-score < 14 (N = 20). The median GCS-score in patients with reduced consciousness was 9 (range 6–12). Groups were comparable except for significantly higher injury severity scores in the impaired mental status group (19 vs. 17, p = 0.007). Length of stay (28 vs. 9 days, p < 0.001) and ICU-stay (8 vs. 0 days, p = 0.005) were longer in patients with decreased GCS-scores. Failure of NOM, total splenectomy rates, complications and mortality did not differ between both study groups. Conclusion This study shows that NOM for blunt splenic trauma is a viable treatment modality in well-equipped institutions, regardless of the patients mental status. However, the presence of neurologic impairment is associated with prolonged ICU-stay and hospitalization. We recommend, in institutions with adequate monitoring facilities, to attempt nonoperative management for blunt splenic injury, in all hemodynamically stable patients without hollow organ injuries, also in the case of reduced consciousness.

Abstract Background Resuscitative emergency thoracotomy is a potential life-saving procedure but is rarely performed outside of busy trauma centers. Yet the intervention cannot be deferred nor centralized for critically injured patients presenting in extremis. Low-volume experience may be mitigated by structured training. The aim of this study was to describe concurrent development of training and simulation in a trauma system and associated effect on one time-critical emergency procedure on patient outcome. Methods An observational cohort study split into 3 arbitrary time-phases of trauma system development referred to as ‘early’, ‘developing’ and ‘mature’ time-periods. Core characteristics of the system is described for each phase and concurrent outcomes for all consecutive emergency thoracotomies described with focus on patient characteristics and outcome analyzed for trends in time. Results Over the study period, a total of 36 emergency thoracotomies were performed, of which 5 survived (13.9%). The “early” phase had no survivors (0/10), with 2 of 13 (15%) and 3 of 13 (23%) surviving in the development and mature phase, respectively. A decline in ‘elderly’ (>55 years) patients who had emergency thoracotomy occurred with each time period (from 50%, 31% to 7.7%, respectively). The gender distribution and the injury severity scores on admission remained unchanged, while the rate of patients with signs on life (SOL) increased over time. Conclusion The improvement over time in survival for one time-critical emergency procedure may be attributed to structured implementation of team and procedure training. The findings may be transferred to other low-volume regions for improved trauma care.

Abstract Background Endothelial glycocalyx (EG) abnormal degradation were widely found in critical illness. However, data of EG degradation in multiple traumas is limited. We performed a study to assess the EG degradation and the correlation between the degradation and organ functions in polytrauma patients. Methods A prospective observational study was conducted to enroll health participants (control group) and polytrauma patients (trauma group) at a University affiliated hospital between Feb 2020 and Oct 2020. Syndecan1 (SDC1) and heparin sulfate (HS) were detected in serum sample of both groups. In trauma group, injury severity scores (ISS) and sequential organ failure assessments (SOFA) were calculated. Occurrences of acute kidney injury (AKI), trauma-induced coagulopathy (TIC) within 48 h and 28-day all-cause mortality in trauma group were recorded. Serum SDC1 and HS levels were compared between two groups. Correlations between SDC1/HS and the indicators of organ systems in the trauma group were analyzed. ROC analyses were performed to assess the predictive value of SDC1 and HS for AKI, TIC within 48 h, and 28-day mortality in trauma group. Results There were 45 polytrauma patients and 15 healthy participants were collected, totally. SDC1 and HS were significantly higher in trauma group than in control group (69.39 [54.18–130.80] vs. 24.15 [13.89–32.36], 38.92 [30.47–67.96] vs. 15.55 [11.89–23.24], P < 0.001, respectively). Trauma group was divided into high degradation group and low degradation group according to SDC1 median. High degradation group had more severe ISS, SOFA scores, worse organ functions (respiratory, kidney, coagulation and metabolic system), and higher incidence of hypothermia, acidosis and shock. The area under the receiver operator characteristic curves (AUC) of SDC1 to predict AKI, TIC occurrence within 48 h and 28-day mortality were 0.838 (95%CI: 0.720–0.957), 0.700 (95%CI: 0.514–0.885) and 0.764 (95%CI: 0.543–0.984), respectively. Conclusions EG degradation was elevated significantly in polytrauma patients, and the degradation was correlated with impaired respiratory, kidney, coagulation and metabolic systems in early stage. Serum SDC1 is a valuable predictive indicator of early onset of AKI, TIC, and 28-day mortality in polytrauma patients.

Score Inflation

Introduction Extensive research relying on Injury Severity Scores (ISS) reports a mortality benefit from routine non-selective thoracic CTs (an integral part of pan-computed tomography (pan-CT)s). Recent research suggests this mortality benefit may be artifact. We hypothesized that the use of pan-CTs inflates ISS categorization in patients, artificially affecting admission rates and apparent mortality benefit. Methods Eight hundred and eleven patients were identified with an ISS >15 with significant findings in the chest area. Patient charts were reviewed and scores were adjusted to exclude only occult injuries that did not affect treatment plan. Pearson chi-square tests and multivariable logistic regression were used to compare adjusted cases vs non-adjusted cases. Results After adjusting for inflation, 388 (47.8%) patients remained in the same ISS category, 378 (46.6%) were reclassified into 1 lower ISS category, and 45 (5.6%) patients were reclassified into 2 lower ISS categories. Patients reclassified by 1 category had a lower rate of mortality ( P < 0.001), lower median total hospital LOS ( P < .001), ICU days ( P < .001), and ventilator days ( P = 0.008), compared to those that remained in the same ISS category. Conclusion Injury Severity Score inflation artificially increases survival rate, perpetuating the increased use of pan-CTs. This artifact has been propagated by outdated mortality prediction calculation methods. Thus, prospective evaluations of algorithms for more selective CT scanning are warranted.
