ABSTRACT

BACKGROUND: Management of colon injuries has significantly evolved in the recent decades resulting in considerably decreased morbidity and mortality. We set out to investigate penetrating colon injuries in a high-volume urban academic trauma center in South Africa. METHODS: All patients with penetrating colon injuries admitted between 1/2015 and 1/2018 were prospectively enrolled. Data collection included demographics, injury profile and outcomes. Primary outcome was in-hospital mortality. Secondary outcome was morbidity. RESULTS: Two-hundred and five patients were included in the analysis. Stab and gunshot wounds constituted 18% and 82% of the cases, respectively. Mean age was 28.9 (10.2) years and 96.1% were male. Median injury severity score (ISS) and penetrating abdominal trauma index (PATI) were 16 (9-25) and 19 (10-26), respectively. A total of 47.8% of the patients had a complication per Clavien-Dindo classification. Colon leak rate was 2.4%. Wound and abdominal organ/space infection rate was 15.1 and 6.3%, respectively. Overall in-hospital mortality was 9.3%. Risk factors for mortality were higher ISS and PATI, shock on admission, need for blood transfusion, intra-abdominal vascular injury, damage control surgery, and extra-abdominal severe injuries. CONCLUSIONS: Contemporary overall complication rate remains high in penetrating colon injuries, however, anastomotic leak rate is decreasing. Colon injury associated mortality is related to overall injury burden and hemorrhage rather than to colon injuries.

ABSTRACT

BACKGROUND AND AIMS: Cardiac injuries are highly lethal lesions following trauma and most of the patients decease in pre-hospital settings. However, studies on cardiac trauma in Estonia are scarce. Thus, we set out to study cardiac injuries admitted to Estonian major trauma facilities during 23 years of Estonian independence. MATERIALS AND METHODS: After the ethics review board approval, all consecutive patients with cardiac injuries per ICD-9 (861.0 and 861.1) and ICD-10 codes (S.26) admitted to the major trauma facilities between 1 January 1993 and 31 July 2016 were retrospectively reviewed. Cardiac contusions were excluded. Data collected included demographics, injury profile, and in-hospital outcomes. Primary outcome was mortality. Secondary outcomes were cardiac injury profile and hospital length of stay. RESULTS: During the study period, 37 patients were included. Mean age was 33.1 ± 12.0 years and 92% were male. Penetrating and blunt trauma accounted for 89% and 11% of the cases, respectively. Thoracotomy and sternotomy rates for cardiac repair were 80% and 20%, respectively. Most frequently injured cardiac chamber was left ventricle at 49% followed by right ventricle, right atrium, and left atrium at 34%, 17%, and 3% of the patients, respectively. Multi-chamber injury was observed at 5% of the cases. Overall hospital length of stay was 13.5 ± 16.7 days. Overall mortality was 22% (n = 8) with uniformly fatal outcomes following left atrial and multi-chamber injuries. CONCLUSION: Overall, 37 patients with cardiac injuries were hospitalized to national major trauma facilities during the 23-year study period. The overall in-hospital mortality was 22% comparing favorably with previous reports. Risk factors for mortality were initial Glasgow Coma Scale < 9, pre-hospital cardiopulmonary resuscitation, and alcohol intoxication.

ABSTRACT

PURPOSE: Severe traumatic brain injury (TBI) is the predominant cause of death and disability following trauma. Several studies have observed improved survival in TBI patients exposed to ß-blockers, however, the effect on functional outcome is poorly documented. METHODS: Adult patients with severe TBI (head AIS ≥ 3) were identified from a prospectively collected TBI database over a 5-year period. Patients with neurosurgical ICU length of stay <48 h and those dying within 48 h of admission were excluded. Patients exposed to ß-blockers ≤ 48 h after admission and who continued with treatment until discharge constituted ß-blocked cases and were matched to non ß-blocked controls using propensity score matching. The outcome of interest was Glasgow Outcome Scores (GOS), as a measure of functional outcome up to 12 months after injury. GOS ≤ 3 was considered a poor outcome. Bivariate analysis was deployed to determine differences between groups. Odds ratio and 95% CI were used to assess the effect of ß-blockers on GOS. RESULTS: 362 patients met the inclusion criteria with 21% receiving ß-blockers during admission. After propensity matching, 76 matched pairs were available for analysis. There were no statistical differences in any variables included in the analysis. Mean hospital length of stay was shorter in the ß-blocked cases (18.0 vs. 26.8 days, p < 0.01). The risk of poor long-term functional outcome was more than doubled in non-ß-blocked controls (OR 2.44, 95% CI 1.01-6.03, p = 0.03). CONCLUSION: Exposure to ß-blockers in patients with severe TBI appears to improve functional outcome. Further prospective randomized trials are warranted.

ABSTRACT

BACKGROUND: Injuries result in 5.8 million global fatalities annually and are the leading cause of death in younger individuals. Nevertheless, population-based autopsy investigations on traumatic deaths are scarce. We set out to study all consecutive autopsies on traumatic fatalities performed in a 5-year time segment in Estonia. METHODS: After the ethics review board approval, all consecutive autopsies after blunt or penetrating deaths occurring in prehospital or in-hospital settings between January 1, 2009, and December 31, 2013, were retrospectively reviewed using the National Forensic Medicine Database. Fatalities due to suffocation, intoxication, burns, or freezing were excluded. Data collection included demographics, mechanism of injuries, cause of death, and a detailed injury profile. Primary outcome was cause of death. Secondary outcomes included injury patterns. RESULTS: Overall, 1344 autopsies were included. 75.7% of deaths were following blunt trauma. Mean age was 50.4 ± 18.5 years, and 77.1% were male. A total of 71.8% of deaths occurred in the prehospital setting. Accidents, assaults, and suicides constituted 64.4, 20.5, and 15.2% of deaths, respectively. A total of 51.1% of injury fatalities had a positive blood alcohol level (BAL). Mean injury severity score was 39.7 ± 23.9. Most common cause of death was due to head injuries at 50.5% followed by hemorrhage at 30.4%. Cardiac and aortic injuries were the predominant cause of hemorrhage-related fatalities. CONCLUSIONS: The current population-based investigation documented brain injury as the predominant cause of death followed by cardiac and aortic injuries. High incidence of positive BAL among injury fatalities requires national initiatives for alcohol harm reduction and law enforcement efforts.

ABSTRACT

PURPOSE: Trauma mechanisms and patterns of severe injuries during the Estonian independence have not been evaluated. The aim of the study was to compare the incidence and outcomes of severe injuries between time periods of early independence from the Soviet Union and the present time. METHODS: After the ethics review board approval, all adult trauma admissions to major trauma facilities in 1993-1994 and 2013-2014 with Injury Severity Score >15 were identified. Data collection included demographics, injury severity variables, interventions, and in-hospital outcomes. Primary outcome was in-hospital mortality. Secondary outcomes included incidence of penetrating trauma, hospital length of stay (HLOS), and in-hospital complications. Primary outcome difference comparing the two time segments was determined using logistic regression analysis. RESULTS: A total of 1064 patients were included, 593 and 471 from 1993-1994 to 2013-2014, respectively. Incidence of penetrating trauma during 1993-1994 was 11.1 % and in 2013-2014 at 6.4 % (p = 0.007). Gunshot injuries constituted 62.1 and 23.3 % of all penetrating trauma in 1993-1994 and 2013-2014, respectively (p < 0.001). The overall mean HLOS was 15.5 ± 19.8 days and did not differ between the periods. The rate of adjusted complications showed a trend for a decreased incidence (adj. p = 0.064). Adjusted mortality rate was 50.3 and 16.4 % during 1993-1994 and 2013-2014, respectively (adj. OR 7.01; 95 % CI 4.69-10.47; p < 0.001). CONCLUSIONS: Effective law enforcement, gun control, evolution of trauma system, and reduction of interpersonal violence have all contributed to a significant decrease in penetrating trauma incidence and all-cause adjusted mortality during the 20 years of Estonian independence.

ABSTRACT

PURPOSE: The purpose of this study was to investigate epidemiology of severe injuries in Estonia while comparing outcomes at regional trauma facilities. METHODS: After the ethics review board approval, all consecutive trauma admissions with Injury Severity Score (ISS) > 15 to North Estonia Medical Center/Tallinn Children's Hospital (NEMC + TCH) and Tartu University Hospital (TUH) were identified between 1/1/2013 and 31/12/2013. Data collection included demographics, admission data, injury severity variables, interventions, and in-hospital outcomes. Primary outcome was in-hospital mortality. Secondary outcomes were complications per Clavien-Dindo and hospital length of stay (HLOS). Logistic regression analysis was used to compare adjusted mortality between the two regional hospitals. RESULTS: A total of 256 patients met inclusion criteria. The mean ISS for the cohort was 23.6 ± 7.8, 13.3 % were hypotensive on admission, and 44.1 % had a Glasgow Coma Scale < 9. Overall rate of complications was 40.2 % that did not differ between the facilities. The mean HLOS at the NEMC + TCH and the TUH were 20.1 ± 25.1 and 10.5 ± 11.2 days (p < 0.001), respectively. Overall mortality was 20.7 % (n = 53). Mortality was 25.4 and 14.9 % for the NEMC + TCH and the TUH, respectively (p = 0.04). Logistic regression analysis resulted in comparable mortality at the regional trauma facilities (adj. OR 1.38; 95 % CI 0.66-2.92; p value 0.39). CONCLUSIONS: The annual incidence of injuries with ISS > 15 was 256 cases with overall mortality at 20.7 % in Estonia. We observed comparable adjusted outcomes at the major regional trauma facilities. This study contains benchmarking data on severely injured patients in Estonia providing potential for future trauma care evaluation and regional outcome comparisons.

ABSTRACT

BACKGROUND: Recent studies have suggested that same-admission delayed cholecystectomy is a safe option. Patients with diabetes have been shown to have less favourable outcomes after cholecystectomy, but the impact of timing of operation for acute cholecystitis during the same admission is unknown. METHODS: This was a retrospective analysis of patients undergoing laparoscopic cholecystectomy for acute cholecystitis between 2004 and 2010, from the American College of Surgeons National Surgical Quality Improvement Program database. Patients with no significant co-morbidities (American Society of Anesthesiologists grade I or II) were included. Propensity score matching (PSM) was used to match patients with diabetes with those who did not have diabetes, in a ratio of 1:3, to ensure homogeneity of the two groups. Logistic regression models were applied to adjust for differences between early (within 24 h) and delayed (24 h or more) surgical treatment. The primary outcome was development of local and systemic infectious complications. Secondary outcomes were duration of operation and length of hospital stay. RESULTS: From a total of 2892 patients, 144 patients with diabetes were matched with 432 without diabetes by PSM. Delaying cholecystectomy for at least 24 h after admission in patients with diabetes was associated with significantly higher odds of developing surgical-site infections (adjusted odds ratio 4.11, 95 per cent confidence interval 1.11 to 15.22; P = 0.034) and a longer hospital stay. For patients with no diabetes, however, delaying cholecystectomy had no impact on complications or length of hospital stay. CONCLUSION: Patients with diabetes who undergo laparoscopic cholecystectomy 24 h or more after admission may have an increased risk of postoperative surgical-site infection and a longer hospital stay than those undergoing surgery within 24 h of admission.

ABSTRACT

INTRODUCTION: Coagulopathy after severe traumatic brain injury (sTBI) results in a ten-fold increased risk of death. Our aim was to investigate the effect of ETOH intoxication on admission coagulopathy after sTBI. METHODS: Patients with sTBI [Glasgow Coma Scale <9 or evidence of intracranial pathology on computed tomography (CT)] from 1/2010 to 12/2011 were prospectively enrolled. Demographics, clinical characteristics, laboratory values, head CT scan findings, physical examination, injury severity indices, and interventions were recorded. ETOH blood levels were obtained. The incidence of admission coagulopathy was compared between patients who were ETOH-positive (ETOH+) and those who were ETOH-negative (ETOH-). Logistic regression was performed to identify independent risk factors. RESULTS: A total of 216 patients were enrolled. 20.4 % were ETOH+. Admission coagulopathy was significantly lower for ETOH+ patients (15.9 vs. 39.0 %, adjusted p = 0.020). Prothrombin time (PT) and International Normalized Ratio (INR) on admission were significantly lower for ETOH+ patients (16.7 vs. 14.3, adjusted p = 0.016 and 1.35 vs. 1.13, adjusted p = 0.040, respectively). Injury Severity Score ≥25, hypotension, and loss of gray/white differential were identified as independent risk factors for the development of admission coagulopathy. ETOH intoxication was the only protective predictor [AOR (95 % CI): 0.32 (0.12, 0.84), adjusted p = 0.021]. CONCLUSIONS: ETOH intoxication is associated with a lower incidence of admission coagulopathy in patients with sTBI. Further research is warranted.

ABSTRACT

BACKGROUND: The use of low-molecular-weight heparin (LMWH) for the chemoprophylaxis of venous thromboembolism (VTE) in trauma patients is supported by Level-1 evidence. Because Enoxaparin was the agent used in the majority of studies for establishing the efficacy of LMWH in VTE, it remains unclear if Dalteparin provides an equivalent effect. OBJECTIVE: To compare Dalteparin to Enoxaparin and investigate their equivalence as VTE prophylaxis in trauma. PATIENTS/SETTING: Trauma patients receiving VTE chemoprophylaxis in the Surgical Intensive Care Unit of a Level-1 Trauma Center from 2009 (Enoxaparin) to 2010 (Dalteparin) were included. MEASUREMENTS: The primary outcome was the incidence of clinically significant VTE. Secondary outcomes included heparin-induced thrombocytopenia (HIT), major bleeding, and drug acquisition cost savings. Equivalence margins were set between -5 and 5 %. MAIN RESULTS: A total of 610 patient records (277 Enoxaparin, 333 Dalteparin) were reviewed. The two study groups did not differ significantly: blunt trauma 67 vs. 62 %, p = 0.27; mean Injury Severity Score (ISS) 17 ± 10 vs. 16 ± 10, p = 0.34; Acute Physiology and Chronic Health Evaluation (APACHE) II score 17 ± 9 vs. 17 ± 10, p = 0.76; time to first dose of LMWH 69 ± 98 vs. 65 ± 67 h, p = 0.57). The rates of deep venous thrombosis (DVT) (3.2 vs. 3.3 %, p = 1.00), pulmonary emboli (PE) (1.8 vs. 1.2 %, p = 0.74), and overall VTE (5.1 vs. 4.5 %, p = 0.85) did not differ. The absolute difference in the incidence of overall VTE was 0.5 % [95 % confidence interval (CI): -2.9, 4.0 %, p = 0.85]. The 95 % CI was within the predefined equivalence margins. There were no significant differences in the frequency of HIT or major bleeding. The total year-on-year cost savings, achieved with 277 patients during the switch to Dalteparin, was estimated to be $107,778. CONCLUSIONS: Dalteparin is equivalent to Enoxaparin in terms of VTE in trauma patients and can be safely used in this population, with no increase in complications and significant cost savings.

ABSTRACT

PURPOSE: The impact of anemia and restrictive transfusion strategies in traumatic brain injury (TBI) is unclear. The purpose of this study was to examine the outcome of varying degrees of anemia in patients who have sustained a TBI. METHODS: We performed a retrospective study of all adult patients with isolated blunt TBI admitted between January 2003 and June 2010. The impact of increasing severity of anemia (Hb ≤8, ≤9, or ≤10 g/dl measured on three consecutive draws within the first 7 days of admission) and transfusions on complications, length of stay, and mortality was examined using univariate and multivariate analysis. RESULTS: Of the 31,648 patients with blunt trauma admitted to the trauma service during the study period, 812 had an isolated TBI, among which 196 (24.1 %) met at least one of the anemia thresholds within the first 7 days [78 % male, mean age 47 ± 23 years, Injury Severity Score 16 ± 8, and head Abbreviated Injury Scale 3.3 ± 1.0]. Using a logistic regression model, anemia even as low as 8 g/dl was not associated with an increase in mortality [AOR8 = 0.8 (0.2, 3.2), p = 0.771; AOR9 = 0.8 (0.4, 1.6), p = 0.531; AOR10 = 0.6 (0.3, 1.3), p = 0.233] or complications. However, for all patients, the transfusion of packed red blood cells was associated with a significant increase in septic complications [AOR = 3.2 (1.5, 13.7), p = 0.030]. CONCLUSION: The presence of anemia in patients with TBI as low as 8 g/dl was not associated with increased mortality or complications, while the transfusion of red blood cells was associated with a significant increase in septic complications. Prospective evaluation of an optimal transfusion trigger in head-injured patients is warranted.

ABSTRACT

INTRODUCTION: The purpose of this study was to analyze the epidemiology and outcomes after traumatic amputation of the upper (UEA) and lower (LEA) extremities. METHODS: The Los Angeles County + University of Southern California Medical Center trauma registry was utilized to identify all patients sustaining traumatic amputation during the years 1996-2007. The demographics, mechanism of injury, clinical characteristics, associated injuries, surgical procedures, complications, and outcomes were obtained for these patients. RESULTS: During the 12-year study period, 130 patients suffered limb amputation, accounting for 0.25% of all trauma admissions. Thirteen patients (10%) were excluded because they were transferred from another facility after amputation or died in the emergency department. Of the remaining 117 patients, mean age was 38.1 ± 16.4 years and 77.8% were male. The predominant mechanism of injury was automobile versus pedestrian (27.4%), followed by work-related accidents (23.9%). Patients struck by vehicles were more likely to suffer LEA (93.8% versus 6.2%, p < 0.001), while patients with work-related accidents were more likely to sustain UEA (81.5% versus 18.5%, p < 0.001). Only nine patients underwent reattachment, all of which were for UEA and unsuccessful. Overall, 24.8% developed a complication during their hospital course, 55.2% of which were extremity related. Overall mortality was 3.4%, primarily attributed to associated severe traumatic brain injuries and thoracic injuries. Patients with LEA had longer hospital and intensive care unit (ICU) length of stay; however, after adjusting for confounders, this difference did not reach statistical significance (adjusted mean difference: 2.1 and 1.2 days, p = 0.69 and 0.79, respectively). A higher percentage of patients with LEA required discharge to a skilled nursing facility or rehabilitation center when compared with patients with UEA (29.6% versus 4.8%, p = 0.001). CONCLUSIONS: Traumatic limb amputation is a rare consequence of civilian trauma. Amputation is rarely the primary cause of death; however, these devastating injuries are associated with significant intensive care unit and hospital lengths of stay. Although no mortality difference was detected, when compared with patients with upper extremity amputations, patients with lower extremity amputations were more severely injured, required revision extremity surgery more often, had a higher complication rate, and more frequently required discharge to a long-term facility.

ABSTRACT

BACKGROUND AND AIMS: The aim of this study was to investigate the epidemiology of liver injuries and to grade injuries according to the Organ Injury Scale in a population-based study in Stockholm County comprising 1.75 million inhabitants. MATERIAL AND METHODS: Cases were retrieved from the National Board of Forensic Medicine and Public Health and Medical Services Committee Register. Autopsy reports and patients files were studied for liver injuries, associated injuries, age, sex, trauma mechanism, location of the injury, description of the injury, diagnostic and treatment modalities when available. RESULTS: The incidence of traumatic liver injury in 1996 and 1997 was 2.95/100 000 annually. Seventy seven autopsies with liver injuries revealed injury pattern of grade I in 6 cases (8%), grade II in 10 cases (13%), grade III in 21 cases (27%), grade IV in 15 cases (19%), grade V in 16 cases (21%) and grade VI in 9 cases (12%). Twenty four patients revealed injury pattern of grade II in 13 cases (46%), grade III in 4 cases (14%), grade IV in 5 cases (18%) and grade V in 2 cases (7%). CONCLUSIONS: The results demonstrate a low incidence of liver injuries in the studied population. Grade II and III injuries prevail. Surgical management of liver injuries is an infrequent treatment option in Stockholm County and simple operative measures were applied. No complex hepatic injuries were operated upon.
