Introduction: Bladder and ureteral injuries are uncommon in trauma patients but are associated with increased morbidity and mortality. Patients presenting with such injuries may undergo either open surgical repair or laparoscopic repair. We aimed to compare outcomes of open surgical approach and laparoscopy in trauma patients with isolated bladder and ureteral injury. We hypothesized that laparoscopy is associated with improved outcomes., Methods: We performed a 2017 review of American College of Surgeons Trauma Quality Improvement Program and identified trauma patients with bladder and ureteral injury who underwent open surgical repair or laparoscopy. A 1:1 propensity score matching was performed adjusting for demographics, emergency department vitals (systolic blood pressure, heart rate, Glasgow Coma Scale), mechanism of injury, Injury Severity Score, each body region Abbreviated Injury Scale score, and transfusion units. Outcomes were rates of in-hospital major complications and mortality., Results: Of the 1,004,440 trauma patients, 384 patients (open: 192 and laparoscopy: 192) were matched and included. The mean age was 36 ± 15 y, Injury Severity Score was 27 [27-48], 77% were males, and 56% of patients had a blunt mechanism of injury, and 44% had penetrating injuries. Overall mortality was 7.3%. On univariate analysis, mortality was lower in the open group as compared to the laparoscopy group (10.4% versus 4.2%, P = 0.019) and survivor-only hospital length of stay was longer in the open group (8 [8-9] versus 7 [5-11], P = 0.008). There was no difference in overall major complications (23% versus 21%, P = 0.621). On multivariate analysis, open surgical repair was independently associated with lower odds of mortality (adjusted odds ratio: 0.405, 95% confidence interval: [0.17-0.95], P-value = 0.038) CONCLUSIONS: In our analysis open surgical repair of bladder and ureteral injuries was associated with lower mortality with other outcomes being similar when compared to laparoscopy. Laparoscopic surgical repair may not have an advantage over the open surgical repair for bladder and ureteral injuries. Further prospective studies are needed to delineate the ideal surgical approach for these injuries., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: Efficient Emergency Department (ED) throughput depends on several factors, including collaboration and consultation with surgical services. The acute care surgery service (ACS) collaborated with ED to implement a new process termed "FASTPASS" (FP), which might improve patient-care for those with acute appendicitis and gallbladder disease. The aim of this study was to evaluate the 1-year outcome of FP., Methods: FASTPASS is a joint collaboration between ACS and ED. ED physicians were provided with a simple check-list for diagnosing young males (<50-year old) with acute appendicitis (AA) and young males or females (<50-year old) with gallbladder disease (GBD). Once ED deemed patients fit our FP check-list, patients were directly admitted (FASTPASSed) to the observation unit. The ACS then came to evaluate the patients for possible surgical intervention. We performed outcome analysis before and after the institution of the FP. Outcomes of interest were ED length of stay (LOS), time from ED to the operating room (OR) (door-to-knife), hospital LOS (HLOS), and cost., Results: During our 1-year study period, for those patients who underwent GBD/AA surgery, 56 (26%) GBD and 27 (26%) AA patients met FP criteria. Compared to the non-FP patients during FP period, FP halved ED LOS for GBD (7.4 ± 3.0 versus 3.5 ± 1.7 h, P < 0.001) and AA (6.7 ± 3.3 versus. 1.8 ± 1.6 h, P < 0.001). Similar outcome benefits were observed for door-to-knife time, HLOS, and costs., Conclusions: In this study, the FP process improved ED throughput in a single, highly-trained ER leading to an overall improved patient care process. A future study involving multiple EDs and different disease processes may help decrease ED overcrowding and improve healthcare system efficiency., (Copyright © 2020 Elsevier Inc.

Background: Failure to rescue (FTR) is becoming a ubiquitous metric of quality care. The aim of our study is to determine the type and number of complications associated with FTR after trauma., Methods: We reviewed the Trauma Quality Improvement Program including patients who developed complications after admission. Patients were divided as the following: "FTR" if the patient died or "rescued" if the patient did not die. Logistic regression was used to ascertain the effect of the type and number of complications on FTR., Results: A total of 25,754 patients were included with 972 identified as FTR. Logistic regression identified sepsis (odds ratio [OR] = 6.61 [4.72-9.27]), pneumonia (OR = 2.79 [2.15-3.64]), acute respiratory distress syndrome (OR = 4.6 [3.17-6.69]), and cardiovascular complications (OR = 24.22 [19.39-30.26]) as predictors of FTR. The odds ratio of FTR increased by 8.8 for every single increase in the number of complications., Conclusions: Specific types of complications increase the odds of FTR. The overall complication burden will also increase the odds of FTR linearly., Level of Evidence: Level III Prognostic., (Copyright © 2020. Published by Elsevier Inc.)

Background: Statins have been shown to improve outcomes in traumatic brain injury (TBI) in animal models. The aim of our study was to determine the effect of preinjury statins on outcomes in TBI patients., Methods: We performed a 4-y (2014-2017) review of our TBI database and included all patients aged ≥18 y with severe isolated TBI. Patients were stratified into those who were on statins and those who were not and were matched (1:2 ratio) using propensity score matching. The primary outcome was in-hospital mortality. The secondary outcomes were skilled nursing facility disposition, Glasgow Outcome Scale-extended score, and hospital and intensive care unit length of stay (LOS)., Results: We identified 1359 patients, of which 270 were matched (statin: 90, no-statin: 180). Mean age was 55 ± 8y, median Glasgow Coma Scale was 10 (8-12), and median head-abbreviated injury scale was 3 (3-5). Matched groups were similar in age, mechanism of injury, Glasgow Coma Scale, Injury Severity Score, neurosurgical intervention, type and size of intracranial hemorrhage, and preinjury anticoagulant or antiplatelet use. The overall in-hospital mortality rate was 18%. Patients who received statins had lower rates of in-hospital mortality (11% versus 21%, P = 0.01), skilled nursing facility disposition (19% versus 28%; P = 0.04), and a higher median Glasgow Outcome Scale-extended (11 [9-13] versus 9 [8-10]; P = 0.04). No differences were found between the two groups in terms of hospital LOS (6 [4-9] versus 5 [3-8]; P = 0.34) and intensive care unit LOS (3 [3-6] versus 4 [3-5]; P = 0.09)., Conclusions: Preinjury statin use in isolated traumatic brain injury patients is associated with improved outcomes. This finding warrants further investigations to evaluate the potential beneficial role of statins as a therapeutic drug in a TBI., Level of Evidence: Level III Therapeutic., (Copyright © 2019 Elsevier Inc.

Background: Alcoholism is associated with variable effects on the coagulation system. Therefore, the aim of our study was to analyze the currently unknown association between chronic alcohol consumption and the risk of venous thromboembolism, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE)., Methods: We performed a 2-y (2013-2014) analysis of the American College of Surgeons Trauma Quality Improvement Program database. All trauma patients with an Injury Severity Score (ISS) > 16 were included. We excluded patients with acute alcohol intoxication, hematologic disorders, and cancer. Patients were divided into two groups (alcoholic and nonalcoholic) and were matched using propensity score matching (1:1) for demographics, ISS, injury location, and admission vitals. Outcomes measures were the prevalence of venous thromboembolism in each group., Results: Of the 91,066 trauma patients included in our analysis, 35,460 patients were matched (alcoholics: 17,730; nonalcoholics: 17,730). The mean was age 45 ± 18 y, and 81% were males. Matched groups were similar in age (P = 0.32), heart rate (P = 0.31), systolic blood pressure (P = 0.46), location of injury (P = 0.85), ISS (P = 0.76), and Glasgow Coma Scale (P = 0.38). Prevalence of DVT was lower in alcoholics compared with nonalcoholics (2.34% versus 5.12%, P = 0.01). The overall incidence of PE was 1.2%, and there was no difference between the two groups (1.1% versus 1.3%, P = 0.22). Similarly, there was no difference in mortality (14.8% versus 15.4%, P = 0.32) between the groups., Conclusions: Chronic alcohol consumption is associated with a low risk of DVT in trauma patients. This association warrants further investigation of the possible physiological effects of alcohol in trauma patients., Level of Evidence: Level III Prognostic., (Copyright © 2019 Elsevier Inc.

Background: Numerous factors contribute to advanced disease or increased complications in patients with acute appendicitis (AA). This study aimed to identify risk factors associated with AA perforation, including the effect of system time (ST) delay, after controlling for patient time (PT) delay. In this study, PT was controlled (to less than or equal to 24 h) to better understand the effect of ST delay on AA perforation., Methods: Medical records of patients who underwent surgery for AA at a tertiary referral hospital from October 2009 through September 2013 were reviewed. Data collected included demographics, body mass index, presence of fecalith, PT (i.e., duration of time from symptom onset to arrival in emergency department), and ST (i.e., duration of time from arrival in emergency department to operating room). AA was classified as simple (acute, nonperforated) versus advanced (gangrenous, perforated)., Results: Seven hundred forty-seven patients underwent surgery for AA. After excluding patients with PT > 24 h, 445 patients fit the study criteria, of which 358 patients with simple AA and 87 patients with advanced disease. Advanced appendicitis patients were older and had higher body mass index, longer PT, higher WBC, and higher incidence of fecaliths. Both groups had similar ST. Risk factors for advanced appendicitis after multiple regression analysis are age >50 y old, WBC >15,000, the presence of fecaliths, and PT delay >12 h., Conclusions: Once PT delay was limited to ≤24 h, the ST delay of >12 h did not adversely affect the incidence of advanced AA. Age >50 y, WBC >15,000, PT delay >12 h, and the presence of fecaliths were identified as risk factors associated with advanced AA., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: A significant portion of patients sustaining traumatic brain injury (TBI) are on antiplatelet medications. The reversal of P2Y12 agents after intracranial hemorrhage (ICH) remains unclear. The aim of our study is to evaluate outcomes after TBI in patients who are on preinjury P2Y12 inhibitors and received a platelet transfusion., Methods: We analyzed our prospectively maintained TBI database from 2013 to 2016 and included all patients with isolated ICH who were on P2Y12 inhibitors (Clopidogrel, Prasugrel, Ticagrelor). Regression analysis was performed adjusting for demographics and injury parameters. Outcome measures included progression of ICH, adverse discharge disposition (skilled nursing facility), and mortality., Results: A total 243 patients with ICH on preinjury P2Y12 inhibitor met our inclusion criteria and were analyzed. Mean age was 55 ± 18 y, 58% were males and 60% were white and median injury severity score was 13 [9-18]. 73.6% received platelet transfusion after admission. The median packs of platelet transfusion were 1 [1-2] units. After controlling for confounders, patients who received platelet transfusion had a lower rate of progression (OR: 0.68, P = 0.01) and decreased rate of neurosurgical intervention (OR: 0.80, P = 0.03). Overall mortality was 12.3%. Patients on P2Y12 inhibitors who received platelet transfusion had lower odds of discharge to a skilled nursing facility (OR: 0.75, P = 0.02) and mortality (OR: 0.85, P = 0.04)., Conclusions: Platelet transfusion after isolated traumatic ICH in patients on P2Y12 inhibitors is associated with improved outcomes. Platelet transfusion was associated with decreased risk of progression of ICH, neurosurgical intervention, and mortality. Further randomized studies to validate the use of platelet transfusion and define the optimal dose in patients on P2Y12 inhibitors are warranted., (Copyright © 2018 Elsevier Inc.

Background: Exsanguinating trauma patients often require massive blood transfusion (defined as transfusion of 10 or more pRBC units within first 24 h). The aim of our study is to assess the outcomes of trauma patients receiving massive transfusion at different levels of trauma centers., Methods: Two-y (2013-2014) retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program. We included all adult trauma patients who received massive transfusion (MT) of blood. Outcome measures were mortality, hospital length of stay, intensive care unit-free and ventilator-free days, blood products received, and complications., Results: We analyzed a total of 416,957 patients, of which 2776 met the inclusion criteria and included in the study. Mean age was 40.6 ± 20 y, 78.3% were males and 33.1% of the injuries were penetrating. Median injury severity score [IQR] was 29 [18-40], median [IQR] Glasgow Coma Scale 10[4-15]. Mean packed red blood cells transfusion in the first 24 h was 20 ± 13 units and mean plasma transfusion was 13 ± 11 units. Overall in-hospital mortality was 43.5%. Receiving MT in level I trauma center was independently associated with lower rates of mortality (odds ratio [OR]: 0.75 [0.46-0.96], P < 0.001). Higher injury severity score (OR: 1.020 [1.010-1.030], P < 0.001) and increased units of packed red blood cells transfused (OR: 1.067 [1.041-1.093], P < 0.001) were independently associated with increased mortality. However, there was no association between teaching status, age, gender, emergency department vitals, and units of plasma transfused., Conclusions: Hemorrhage continues to remain one of the most common cause of death after trauma. Almost half of the patients who received massive transfusion died. Patients who receive massive blood transfusion in a level I trauma centers have improved survival compared with level II trauma centers., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: The aim of our study was to evaluate outcomes in patients who are admitted on weekend compared with those admitted on a weekday for acute gallstone pancreatitis., Methods: We performed a 3-y (2010-2012) analysis of the Nationwide Inpatient Sample database. Patients with acute gallstone pancreatitis who underwent endoscopic retrograde cholangiopancreatography (ERCP) were included and were divided into two groups: admission on the weekend versus the weekday. Primary outcome measures were time to ERCP, adverse events, and mortality. Secondary outcome measures were hospital length of stay and total cost., Results: A total of 5803 patients with acute gallstone pancreatitis who underwent ERCP were included in our study; of which 22.6% were admitted on the weekend, whereas 77.4% were admitted on a weekday. Mean age was 57 ± 18 y and 57.1% were female. Within 24 h, the rate of ERCP was higher in patients admitted on the weekday compared with those admitted on the weekend (40% versus 24%; P < 0.001). Similarly, by 48 h, the rate of ERCP was higher in the weekday group (69% versus 49%, P < 0.001). Patients admitted over the weekends had higher complications rate (P = 0.03), hospital length of stay (P < 0.001), and the total cost of hospitalization (P < 0.001) compared with the weekday group with no difference in in-hospital mortality., Conclusions: Patients admitted on weekends for acute gallstone pancreatitis experience a delay in getting ERCP and have higher complications, prolonged hospital stay, and increased hospital costs compared with those admitted on weekdays., (Copyright © 2018 Elsevier Inc.

Background: Thromboprophylaxis with oral Xa inhibitors (Xa-Inh) are recommended after major orthopedic operation; however, its role in spine trauma is not well-defined. The aim of our study was to assess the impact of Xa-Inh in spinal trauma patients managed nonoperatively., Methods: A 4-y (2013-2016) review of the Trauma Quality Improvement Program database. We included all patients with an isolated spine trauma (Spine-abbreviated injury scale ≥3 and other-abbreviated injury scale <3) who were managed nonoperatively and received thromboprophylaxis with either low molecular weight heparin (LMWH) or Xa-Inh. Patients were divided into two groups based on the thromboprophylactic agent received: Xa-Inh and LMWH and were matched in a 1:2 ratio using propensity score matching for demographics, vitals and injury parameters, and level of spine injury. Outcomes were rates of deep venous thrombosis, pulmonary embolism, and mortality., Results: We analyzed a total of 58,936 patients, of which 1056 patients (LMWH: 704, Xa-Inh: 352) were matched. Matched groups were similar in demographics, vital and injury parameters, length of hospital stay (P = 0.31), or time to thromboprophylaxis (P = 0.79). Patients who received Xa-Inh were less likely to develop a deep venous thrombosis (2.3% versus 5.7%, P < 0.01). There were no differences in the rate of pulmonary embolism (P = 0.73), postprophylaxis packed red blood cells transfusions (P = 0.79), postprophylaxis surgical decompression of spinal column (P = 0.75), and mortality rate (P = 0.77)., Conclusions: Oral Xa-Inh seems to be more effective as prophylactic pharmacologic agent for the prevention of deep venous thrombosis in patients with nonoperative spinal trauma compared to LMWH. The two drugs had similar safety profile. Further prospective trials should be performed to change current guidelines., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Management of colonic injuries (colostomy [CO] versus primary anastomosis [PA]) among pediatric patients remains controversial. The aim of this study was to assess outcomes in pediatric trauma patient with colonic injury undergoing operative intervention., Methods: The National Trauma Data Bank (2011-2012) was queried including patients with isolated colonic injury undergoing exploratory laparotomy with PA or CO with age ≤18 y. Missing value analysis was performed. Patients were stratified into two groups: PA and CO. Outcome measures were mortality, in-hospital complications, and hospital length of stay. Multivariate regression analysis was performed., Results: A total of 1151 patients included. Mean ± standard deviation age was 11.61 ± 2.8 y, and median [IQR] Injury Severity Score was 12 [8-16]; 39% (n = 449) of the patients had CO, and 35.6% (n = 410) were managed in pediatric trauma centers (PC). Patients with CO had a higher Injury Severity Score (P < 0.001), a trend toward lower blood pressure (P = 0.40), and an older age (P < 0.001). There was no difference in mortality between the PA and CO groups. However, patients who underwent PA had a shorter length of stay (P < 0.001) and lower in-hospital complications (P < 0.001). A subanalysis shows that, after controlling for all confounding factors, patients managed in PC were 1.2 times (1.2 [1.1-2.1], P = 0.04) more likely to receive a CO than those patients managed in adult trauma centers (AC). Moreover, there was no difference in mortality between the AC and the PC (P = 0.79)., Conclusions: Our data demonstrate no difference in mortality in pediatric trauma patients with colonic injury who undergo primary repair or CO. However, adult trauma centers had lower rates of CO performed as compared to a similar cohort of patients managed in pediatric trauma centers. Further assessment of the reasons underlying such differences will help improve patient outcomes., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Introduction: Early initiation of thromboprophylaxis is highly desired in pelvic fracture patients, but it is often delayed due to the fear of hemorrhage. Aim of our study was to assess the safety of early initiation of venous thromboprophylaxis in patients with pelvic trauma managed nonoperatively., Methods: Three-year (2010-2012) retrospective study of trauma patients with pelvic fractures who were managed nonoperatively and received thromboprophylaxis with low-molecular-weight heparin (LMWH). Patients were stratified in two groups based on the timing of initiation of prophylaxis; early (initiation within first 24 h) and late (after 24 h). Primary outcome measures included decrease in hemoglobin (Hb) levels, number of packed red blood cell (pRBC) units transfused, and the need for hemorrhage control (operative or angioembolization) after initiation of prophylaxis. Regression analysis was performed., Results: 255 patients were included (158 in early and 97 in late group). Mean ± standard deviation age was 48.2 ± 23.3 y, and 50.6% were male. After adjusting for confounders, there was no difference between the two groups in the decrease in Hb levels (b = 0.087, 95% confidence interval [CI] = -0.253 to 1.025; P = 0.23) or pRBC units transfused (b = -0.005, 95% CI = -0.366 to 0.364; P = 0.75).One patient required hemorrhage control postprophylaxis and belonged to the late group. Subanalysis of patients with signs of bleeding (n = 52) showed no difference between the two groups in the decrease in Hb levels or pRBC units transfused. Patients who received LMWH after 24 h had a higher incidence of symptomatic deep venous thrombosis and a longer hospital length of stay., Conclusions: Early initiation of thromboprophylaxis with LMWH in patients with pelvic fractures managed nonoperatively is safe and decreases the risk of symptomatic deep venous thrombosis., (Copyright © 2017 Elsevier Inc.

Background: As the population ages, increasing number of geriatric patients sustain traumatic brain injury (TBI). Communication of accurate prognostic information is crucial for making informed decisions on behalf of such patients. Therefore, the aim of our study was to develop a simple and clinically applicable tool that accurately predicts the prognosis in geriatric TBI patients., Methods: We performed a 1-y (2011) retrospective analysis of isolated geriatric TBI patients (age ≥65 y, head abbreviated injury score [AIS] ≥ 3, and other body AIS < 3) in the National Trauma Data Bank. We calculated a Glasgow Coma Scale (GCS)-age prognosis (GAP) score (age/GCS score) for all patients. Outcome measures were in-hospital adverse outcomes (mortality and Rehab/skilled nursing facility discharge disposition). Regression analysis and receiver operator characteristic curve analysis were performed to determine the discriminatory power of GAP score., Results: A total of 8750 geriatric patients with TBI were included. Mean age was 77.8 ± 7.1 y, the median (interquartile range) GCS was 15 (13-15), and the median (interquartile range) head AIS was 4 (3-4). The overall in-hospital mortality rate was 12.7%, and 34.2% of the patients were discharged home. As the GAP score increased, the mortality rate increased and discharge to-home decreased. Receiver operator characteristic curve analysis revealed excellent discriminatory power for mortality (area under the curve: 0.826). Above a GAP score of 12, the mortality rate was >50% and more than 45% of the patients were discharged to Rehab/skilled nursing facility., Conclusions: For geriatric patients with TBI, a simple GAP score reliably predicts outcomes. A score above 12 results in a drastic increase in mortality and an adverse discharge disposition. This simple tool may help clinicians provide accurate prognostic information to patients' families., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Studies have proposed a neuroprotective role for alcohol (ETOH) in traumatic brain injury (TBI). We hypothesized that ETOH intoxication is associated with mortality in patients with severe TBI., Methods: Version 7.2 of the National Trauma Data Bank (2007-2010) was queried for all patients with isolated blunt severe TBI (Head Abbreviated Injury Score ≥4) and blood ETOH levels recorded on admission. Primary outcome measure was mortality. Multivariate logistic regression analysis was performed to assess factors predicting mortality and in-hospital complications., Results: A total of 23,983 patients with severe TBI were evaluated of which 22.8% (n = 5461) patients tested positive for ETOH intoxication. ETOH-positive patients were more likely to have in-hospital complications (P = 0.001) and have a higher mortality rate (P = 0.01). ETOH intoxication was an independent predictor for mortality (odds ratio: 1.2, 95% confidence interval: 1.1-2.1, P = 0.01) and development of in-hospital complications (odds ratio: 1.3, 95% confidence interval: 1.1-2.8, P = 0.009) in patients with isolated severe TBI., Conclusions: ETOH intoxication is an independent predictor for mortality in patients with severe TBI patients and is associated with higher complication rates. Our results from the National Trauma Data Standards differ from those previously reported. The proposed neuroprotective role of ETOH needs further clarification., (Copyright © 2014 Elsevier Inc.

Background: Geriatric patients are at higher risk for adverse outcomes after injury because of their altered physiological reserve. Mortality after trauma laparotomy remains high; however, outcomes in geriatric patients after trauma laparotomy have not been well established. The aim of our study was to identify factors predicting mortality in geriatric trauma patients undergoing laparotomy., Methods: A retrospective study was performed of all trauma patients undergoing a laparotomy at our level 1 trauma center over a 6-y period (2006-2012). Patients with age ≥55 y who underwent a trauma laparotomy were included. Patients with head abbreviated injury scale (AIS) score ≥ 3 or thorax AIS ≥ 3 were excluded. Our primary outcome measure was mortality. Significant factors in univariate regression model were used in multivariate regression analysis to evaluate the factors predicting mortality., Results: A total of 1150 patients underwent a trauma laparotomy. Of which 90 patients met inclusion criteria. The mean age was 67 ± 10 y, 63% were male, and median abdominal AIS was 3 (2-4). Overall mortality rate was 23.3% (21/90) and progressively increased with age (P = 0.013). Age (P = 0.02) and lactate (P = 0.02) were the independent predictors of mortality in geriatric patients undergoing laparotomy., Conclusions: Mortality rate after trauma laparotomy increases with increasing age. Age and admission lactate were the predictors of mortality in geriatric population undergoing trauma laparotomies., (Published by Elsevier Inc.)

Background: Variability exits in the ability to predict overall recovery after trauma and inpatient rehabilitation. The aim of this study was to identify factors predicting functional improvement in trauma patients undergoing inpatient rehabilitation., Methods: We performed a 3-y retrospective cohort analysis on a prospectively collected database of all trauma patients discharged from a level I trauma center to a single inpatient rehabilitation center. Patient's Functional Independence Measures (FIM) scores on hospital discharge and on discharge from the rehabilitation center were collected. Delta FIM was defined as the difference in FIM between rehabilitation center discharge and hospital discharge. Multiple linear regressions were performed to identify hospital admission factors associated with delta FIM., Results: We included 160 patients, 69% were male, mean age 54.6 ± 22 y, and median Injury Severity Score 14 [10-50]. Based on rehabilitation admission FIM scores, 29 were totally dependent and 131 were partially dependent. The mean change in FIM was 39.4 ± 13. Age, gender, Glasgow Coma Scale on presentation, Injury Severity Score, systolic blood pressure on presentation, and intensive care unit length of stay were not predictive of delta FIM. Hospital length of stay and head Abbreviated Injury Score on hospital admission were negative predictors of delta FIM., Conclusions: In our study, age as an independent factor was not predictive of functional outcome after injury. The extent of head injury continues to negatively affect the overall functional improvement based on FIM., (Copyright © 2013 Elsevier Inc. All rights reserved.)
