Use of a Bundle Checklist Combined With Physician Confirmation Reduces Risk of Nosocomial Complications and Death in Trauma Patients Compared to Documented Checklist Use Alone.

BACKGROUND: Bundle checklists are increasingly utilized in patient care, but data are inconsistent regarding their efficacy in reducing nosocomial complication rates. We examined whether checklist usage was associated with nosocomial complications; when documented, elements were verified by provider bedside rounds. METHODS: We performed a retrospective cohort study of trauma patients admitted to our hospital during a three-phase implementation of a quality improvement project. For this analysis, patients were categorized under predocumentation (PD), documentation only (DO), or documentation with provider review (PR) cohort based on temporal designations. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between documentation cohorts and nosocomial complications. RESULTS: No difference was observed in mean hospital stay, intensive care unit (ICU) days, or ventilator days. The DO cohort showed no significant differences in the risk of complications. Among ICU patients, when compared with the PD cohort, the PR cohort demonstrated a decreased risk of all complications OR 0.72 (95% CI 0.55-0.93), pulmonary embolus OR 0.29 (95% CI 0.11-0.73), pneumonia OR 0.66 (95% CI 0.50-0.88), and death OR 0.50 (95% CI 0.31-0.79). CONCLUSIONS: Bedside confirmation of bundle checklists during physician extender rounds reduces the risk of pulmonary embolus, pneumonia, and death when compared to chart documentation alone. This study underscores the importance of the team approach to the bundle checklist and it's ability to reduce morbidity and mortality.

Detailed description of all deaths in both the shock and traumatic brain injury hypertonic saline trials of the Resuscitation Outcomes Consortium.

OBJECTIVE: To identify causes and timing of mortality in trauma patients to determine targets for future studies. BACKGROUND: In trials conducted by the Resuscitation Outcomes Consortium in patients with traumatic hypovolemic shock (shock) or traumatic brain injury (TBI), hypertonic saline failed to improve survival. Selecting appropriate candidates is challenging. METHODS: Retrospective review of patients enrolled in multicenter, randomized trials performed from 2006 to 2009. Inclusion criteria were as follows: injured patients, age 15 years or more with hypovolemic shock [systolic blood pressure (SBP) ≤ 70 mm Hg or SBP 71-90 mm Hg with heart rate ≥ 108) or severe TBI [Glasgow Coma Score (GCS) ≤ 8]. Initial fluid administered was 250 mL of either 7.5% saline with 6% dextran 70, 7.5% saline or 0.9% saline. RESULTS: A total of 2061 subjects were enrolled (809 shock, 1252 TBI) and 571 (27.7%) died. Survivors were younger than nonsurvivors [30 (interquartile range 23) vs 42 (34)] and had a higher GCS, though similar hemodynamics. Most deaths occurred despite ongoing resuscitation. Forty-six percent of deaths in the TBI cohort were within 24 hours, compared with 82% in the shock cohort and 72% in the cohort with both shock and TBI. Median time to death was 29 hours in the TBI cohort, 2 hours in the shock cohort, and 4 hours in patients with both. Sepsis and multiple organ dysfunction accounted for 2% of deaths. CONCLUSIONS: Most deaths from trauma with shock or TBI occur within 24 hours from hypovolemic shock or TBI. Novel resuscitation strategies should focus on early deaths, though prevention may have a greater impact.

Advanced prehospital resuscitative care: Can we identify trauma patients who might benefit?

BACKGROUND: Uncontrolled truncal hemorrhage remains the most common cause of potentially preventable death after injury. The notion of earlier hemorrhage control and blood product resuscitation is therefore attractive. Some systems have successfully implemented prehospital advanced resuscitative care (ARC) teams. Early identification of patients is key and is reliant on rapid decision making and communication. The purpose of this simulation study was to explore the feasibility of early identification of patients who might benefit from ARC in a typical US setting. METHODS: We conducted a prospective observational/simulation study at a level I trauma center and two associated emergency medical service (EMS) agencies over a 9-month period. The participating EMS agencies were asked to identify actual patients who might benefit from the activation of a hypothetical trauma center-based ARC team. This decision was then communicated in real time to the study team. RESULTS: Sixty-three patients were determined to require activation. The number of activations per month ranged from 2 to 15. The highest incidence of calls occurred between 4 pm to midnight. Of the 63 patients, 33 were transported to the trauma center. The most common presentation was with penetrating trauma. The median age was 27 years (interquartile range, 24-45 years), 75% were male, and the median Injury Severity Score was 11 (interquartile range, 7-20). Based on injury patterns, treatment received, and outcomes, it was determined that 6 (18%) of 33 patients might have benefited from ARC. Three of the patients died en-route to or soon after arrival at the trauma center. CONCLUSION: The prehospital identification of patients who might benefit from ARC is possible but faces challenges. Identifying strategies to adapt existing processes may allow better utilization of the existing infrastructure and should be a focus of future efforts.

Prospective implementation of an algorithm for bedside intravascular ultrasound-guided filter placement in critically ill patients.

BACKGROUND: Although contrast venography is the standard imaging method for inferior vena cava (IVC) filter insertion, intravascular ultrasound (IVUS) imaging is a safe and effective option that allows for bedside filter placement and is especially advantageous for immobilized critically ill patients by limiting resource use, risk of transportation, and cost. This study reviewed the effectiveness of a prospectively implemented algorithm for IVUS-guided IVC filter placement in this high-risk population. METHODS: Current evidence-based guidelines were used to create a clinical decision algorithm for IVUS-guided IVC filter placement in critically ill patients. After a defined lead-in phase to allow dissemination of techniques, the algorithm was prospectively implemented on January 1, 2008. Data were collected for 1 year using accepted reporting standards and a quality assurance review performed based on intent-to-treat at 6, 12, and 18 months. RESULTS: As defined in the prospectively implemented algorithm, 109 patients met criteria for IVUS-directed bedside IVC filter placement. Technical feasibility was 98.1%. Only 2 patients had inadequate IVUS visualization for bedside filter placement and required subsequent placement in the endovascular suite. Technical success, defined as proper deployment in an infrarenal position, was achieved in 104 of the remaining 107 patients (97.2%). The filter was permanent in 21 (19.6%) and retrievable in 86 (80.3%). The single-puncture technique was used in 101 (94.4%), with additional dual access required in 6 (5.6%). Periprocedural complications were rare but included malpositioning requiring retrieval and repositioning in three patients, filter tilt >/=15 degrees in two, and arteriovenous fistula in one. The 30-day mortality rate for the bedside group was 5.5%, with no filter-related deaths. CONCLUSIONS: Successful placement of IVC filters using IVUS-guided imaging at the bedside in critically ill patients can be established through an evidence-based prospectively implemented algorithm, thereby limiting the need for transport in this high-risk population.

Duration of red cell storage influences mortality after trauma.

BACKGROUND: Although previous studies have identified an association between the transfusion of relatively older red blood cells (RBCs) (storage ≥ 14 days) and adverse outcomes, they are difficult to interpret because the majority of patients received a combination of old and fresh RBC units. To overcome this limitation, we compared in-hospital mortality among patients who received exclusively old versus fresh RBC units during the first 24 hours of hospitalization. METHODS: Patients admitted to a Level I trauma center between January 2000 and May 2009 who received ≥ 1 unit of exclusively old (≥ 14 days) vs. fresh (< 14 days) RBCs during the first 24 hours of hospitalization were identified. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated for the association between mortality and RBC age, adjusted for patient age, Injury Severity Score, gender, receipt of fresh frozen plasma or platelets, RBC volume, brain injury, and injury mechanism (blunt or penetrating). RESULTS: One thousand six hundred forty-seven patients met the study inclusion criteria. Among patients who were transfused 1 or 2 RBC units, no difference in mortality with respect to RBC age was identified (adjusted RR, 0.97; 95% CI, 0.72-1.32). Among patients who were transfused 3 or more RBC units, receipt of old versus fresh RBCs was associated with a significantly increased risk of mortality, with an adjusted RR of 1.57 (95% CI, 1.14-2.15). No difference was observed concerning the mean number of old versus fresh units transfused to patients who received 3 or more units (6.05 vs. 5.47, respectively; p = 0.11). CONCLUSION: In trauma patients undergoing transfusion of 3 or more RBC units within 24 hour of hospital arrival, receipt of relatively older blood was associated with a significantly increased mortality risk. Reservation of relatively fresh RBC units for the acutely injured may be advisable.

Mechanical ventilation in adults who need respiratory assistance.

In the care of postoperative, acutely ill, or traumatically injured patients, hypoxemia and acute respiratory acidosis are commonly encountered life-threatening conditions that require intervention, often via mechanical ventilation. Knowing the indications for initiation of mechanical ventilation in adult patients, the various modes available, and the protocols for weaning and liberation will enable PAs to appropriately evaluate and treat these patients.

Early and prehospital trauma deaths: Who might benefit from advanced resuscitative care?

BACKGROUND: Recent civilian and military data from the United States and the United Kingdom suggest that further reductions in mortality will require prehospital or preoperating room hemorrhage control and blood product resuscitation. The aims of this study were to examine the potential preventability of prehospital and early in-hospital fatalities, and to consider the geographical location of such incidents, to contextualize how the use of advanced resuscitative techniques could be operationalized. METHODS: Retrospective analysis of prehospital and early in-hospital trauma deaths from January to December 2017. Data were obtained from the Coroner/ME's Office. Each death was reviewed by a panel of two trauma surgeons and a forensic pathologist. Anatomical and physiological survivabilities were evaluated separately, and then combined, leading to a holistic assessment of preventability. Incident locations were mapped and analyzed using ArcGIS. RESULTS: Three hundred sixteen trauma deaths were identified. Two hundred thirty-one (73%) were deemed anatomically not survivable; 29 (9%) anatomically survivable, but only with hospital care; 43 (14%) anatomically survivable with advanced prehospital care; and 13 (4%) anatomically survivable with basic prehospital care. Physiologically, 114 (36%) of the patients had been dead for some time when found; 137 (43%) had no cardiorespiratory effort on arrival of Emergency Medical Services (EMS) at the scene; 24 (8%) had cardiorespiratory effort at the scene, but not on arrival at the emergency department; and 41 (13%) had cardiorespiratory effort on arrival at the emergency department, but died shortly after. Combining the assessments, 10 (3%) deaths were deemed probably not preventable, 38 (12%) possibly preventable, and the remaining 278 (85%) not preventable. CONCLUSION: Twelve percent of trauma deaths were potentially preventable and might be amenable to advanced resuscitative interventions. Operationalizing this type of care will be challenging and will require either prehospital doctors, or very highly trained paramedics, nurses, or physician assistants. LEVEL OF EVIDENCE: Epidemiological, level III.

Traumatic brain injury is associated with the development of deep vein thrombosis independent of pharmacological prophylaxis.

INTRODUCTION: Deep venous thrombosis (DVT) is common among trauma patients. If left untreated it may result in lethal pulmonary thromboembolism. Previous studies have suggested that intracranial hemorrhage serves as an independent risk factor for the development of DVT. These studies were not able to exclude anticoagulation therapy as a confounding variable in their analysis. Our objective was to determine the association of traumatic brain injury (TBI) to the formation of DVT irrespective of the use of anticoagulation therapy. METHODS: All patients admitted to an academic level I Trauma Center between 2000 and 2007 with blunt or penetrating injuries were selected for inclusion in this study. Patients who died or who were discharged within 24 hours of admission were excluded in the analysis. TBI was defined as any intraparenchymal hemorrhage or extra-axial intracranial bleeding identified on radiographic imaging or both. Anticoagulation therapy was defined as the uninterrupted use of either subcutaneous lovenox or heparin. Risk ratios and 95% confidence intervals compared the risk of DVT among patients with and without TBI according to the initiation of anticoagulation therapy (no therapy, <24 hours, 24-48 hours, and >48 hours) adjusted for age, gender, race, injury severity, mechanism of injury, spinal injury, and lower extremity fracture. RESULTS: Irrespective of the time of initiation of pharmacologic prophylaxis, TBI is independently associated with the formation of DVT. A threefold to fourfold increased risk of DVT formation is consistent across all prophylaxis groups among patients with TBI. CONCLUSION: The incidence of DVT among injured patients with TBI is significantly higher than those patients without head injury independent of anticoagulation therapy. Rigorous surveillance to detect DVT among trauma patients with TBI should be undertaken and where appropriate alternate means for pulmonary thromboembolism prevention used.

The relationship of blood product ratio to mortality: survival benefit or survival bias?

BACKGROUND: Recent studies show an apparent survival advantage associated with the administration of higher cumulative ratios of fresh frozen plasma (FFP) to packed red blood cells (PRBC). It remains unclear how temporal factors and survival bias may influence these results. The objective of this study was to evaluate the temporal relationship between blood product ratios and mortality in massively transfused trauma patients. METHODS: Patients requiring massive transfusion (>10 units of PRBC within 24 hours of admission) between 2005 and 2007 were identified (n = 134). In-hospital mortality was compared between patients receiving high (>1:2) versus low (<1:2) FFP:PRBC ratios with a regression model, using the FFP:PRBC ratio as a fixed value at 24 hours (method I) and as a time-varying covariate (method II). RESULTS: The FFP:PRBC ratio for all patients was low early and increased over time. Sixty-eight percent of total blood products were given and 54% of deaths occurred during the first 6 hours. Using method I, patients receiving a high FFP:PRBC ratio (mean, 1:1.3) by 24 hours had a 63% lower risk of death (RR, 0.37; 95% CI, 0.22-0.64) compared with those receiving a low ratio (mean, 1:3.7). However, this association was no longer statistically significant (RR, 0.84; 95% CI, 0.47-1.50) when the timing of component product transfusion was taken into account (method II). CONCLUSIONS: Similar to previous studies, an association between higher FFP:PRBC ratios at 24 hours and improved survival was observed. However, after adjustment for survival bias in the analysis, the association was no longer statistically significant. Prospective trials are necessary to evaluate whether hemostatic resuscitation is clinically beneficial.

Management of colon wounds in the setting of damage control laparotomy: a cautionary tale.

BACKGROUND: Although colon wounds are commonly treated in the setting of damage control laparotomy (DCL), a paucity of data exist to guide management. The purpose of this study was to evaluate our experience with the management of colonic wounds in the context of DCL, using colonic wound outcomes after routine, single laparotomy (SL) as a benchmark. METHODS: Consecutive patients during a 7-year period with full-thickness or devitalizing colon injury were identified. Early deaths (<48 hour) were excluded. Colon-related complications (abscess, suture or staple leak, and stomal ischemia) were compared between those managed in the setting of DCL versus those managed by SL, both overall and as stratified by procedure (primary repair, resection and anastomosis, and resection and colostomy). RESULTS: One hundred fifty-seven patients met study criteria: 101 had undergone SL and 56 had undergone DCL. Comparison of DCL patients with SL patients was notable for a significant difference in colon-related complications (30% vs. 12%, p < 0.005) and suture/staple leak in particular (12% vs. 3%, p < 0.05). Stratification by procedure revealed a significant difference in colon-related complications among those that underwent resection and anastomosis (DCL: 39% vs. SL: 18%, p < 0.05), whereas no differences were observed in those who underwent primary repair or resection and colostomy. CONCLUSIONS: Management of colonic wounds in the setting of DCL is associated with a relatively high incidence of complications. The excessive incidence of leak overall and morbidity particular to resection and anastomosis, however, give us pause. Although stoma construction is not without its own complications in the setting of DCL, it may be the safer alternative.

Body mass index affects time to definitive closure after damage control surgery.

BACKGROUND: A growing body of literature demonstrates that irrespective of the mechanism of injury, obesity is associated with significantly worse morbidity and mortality after trauma. Among patients requiring damage control laparotomy (DCL), clinical experience suggests that obesity affects time to definitive closure though this association has never been demonstrated quantitatively. METHODS: All patients at an academic Level I trauma center requiring a DCL between January 2002 and December 2006 (N = 148) were included. Information pertaining to demographic, injury, and clinical characteristics was abstracted from patient medical records. The risk of specific complications including pneumonia, renal failure, and sepsis was compared between normal and overweight/obese patients, as measured by body mass index (BMI). The lengths of intensive care unit (ICU) stay and mechanical ventilation as well as time to abdominal closure were also compared. RESULTS: The risk of pneumonia, sepsis, and renal failure was 2.05-times, 1.77-times, and 2.84-times higher among overweight patients compared with patients with a normal BMI. The risk of pneumonia, sepsis, and renal failure was 2.01-times, 4.24-times, and 1.85-times higher among obese patients compared with those with a normal BMI. Obese patients also had a significantly longer ICU length of stay (28.7 days vs. 15.1 days; p < 0.0001), longer hospitalization (39.3 days vs. 27.0 days; p = 0.008), and time to definitive closure (8.4 days vs. 3.9 days; p = 0.03) compared with patients with a normal BMI. CONCLUSIONS: Among patients requiring DCL, those who are overweight or obese have a prolonged time to definitive closure. These patients also experience a significantly longer ICU course and a higher risk of pneumonia.

Use of extracorporeal membranous oxygenation in the management of refractory trauma-related severe acute respiratory distress syndrome: a national survey of the Eastern Association for the Surgery of Trauma.

OBJECTIVE: To report results of a national survey of provider attitudes, observations, and opinions regarding the use of extracorporeal membranous oxygenation (ECMO) to manage severe acute respiratory distress syndrome (ARDS) in trauma patients. DESIGN: A survey was created to query providers on the use of ECMO in trauma, as well as general management principals related to care of the patient with refractory hypoxic respiratory failure. The survey was sent to all members of Eastern Association for the Surgery of Trauma (EAST). Once completed, the survey was returned to the University of Alabama at Birmingham and results were analyzed. SETTING/PATIENTS: Trauma patients with refractory ARDS. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Respondents were from 37 states, the District of Columbia, and Puerto Rico. 56.9% reported institutional ECMO capabilities, but only 45.2% reported using ECMO for trauma patients. Most respondents (90.2%) reported ECMO use in less than or equal to five trauma patients per year. 20.9% think there is not enough data to support its use in trauma but only 4.7% would absolutely not consider ECMO use for trauma patients. Ranking the preferred modality of treatments for refractory ARDS from most to least preferable is as follows: airway pressure release ventilation, bilevel ventilation, paralysis, prone positioning, inhaled nitric oxide, epoprostenol, high-frequency oscillatory ventilation, corticosteroids, surfactant. CONCLUSIONS: ARDS has a high mortality among trauma patients. Despite its utility in treating severe ARDS and other pulmonary disease processes, ECMO has not been universally embraced by the trauma community. There are an increasing number of studies that suggest that ECMO is a safe and viable treatment option for trauma patients with ARDS. Based on the results of this survey, ECMO use remains limited by trauma providers that care for patients with refractory hypoxic respiratory failure and ARDS, likely due to a combination of knowledge gaps and lack of access to ECMO. LEVEL OF EVIDENCE: Level V.

Transfusions in the less severely injured: does age of transfused blood affect outcomes?

BACKGROUND: Prior studies have demonstrated that transfusion of older stored blood is associated with an increased risk of multiple organ failure, infection, and death. These reports were primarily comprised of severely injured patients, and it remains unknown whether this phenomenon is observed in relatively less injured patients. The purpose of this study was to evaluate the association between the age of stored blood and the morbidity and mortality in a mild to moderately injured patient cohort. METHODS: Blunt trauma patients with Injury Severity Score <25 admitted to a Trauma Intensive Care Unit during 7.5 years who received no blood during the first 48 hours of hospitalization were selected for inclusion. Patients who died within 48 hours of admission were excluded from analysis. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for the association between morbidity or mortality and the age and amount of blood transfused (>48 hours postadmission), adjusted for age, sex, injury severity, thoracic injury, mechanical ventilation, and transfusion volume. RESULTS: During 7.5 years, 1,624 patients met the study criteria. The mean Injury Severity Score was 14.4. Receipt of blood stored beyond 2 weeks was associated with mortality (OR 1.12 [CI 1.02-1.23]), renal failure (OR 1.18 [CI 1.07-1.29]), and pneumonia (OR 1.10 [CI 1.04-1.17]). No such associations were identified, however, concerning the transfusion of blood with a lesser storage age. CONCLUSION: In a mild to moderately injured intensive care unit patient cohort, the receipt of blood stored beyond 2 weeks was independently associated with mortality, renal failure, and pneumonia. The deleterious effect of older blood on patient outcome does not appear to be limited to the severely injured.

Age of transfused blood: an independent predictor of mortality despite universal leukoreduction.

BACKGROUND: The transfusion of relatively older stored blood has been associated with an increased risk of multiple organ failure, infection, and death. It remains unknown whether this phenomenon is mitigated by transfusion of leukoreduced red cell units. The purpose of this study was to evaluate the influence of stored blood age on mortality in injured patients who universally received leukoreduced blood. METHODS: Trauma patients who received > or = 1 unit of blood during the first 24 hours after hospital arrival were selected for inclusion. Patients were stratified both according to total units and "old" units (> or = 14 days) versus "young" units (< 14 days) received in the initial 24 hours. Odds ratios and 95% confidence intervals (CIs) were calculated for the association between mortality and the age and amount of blood transfused, adjusted for age, sex, injury severity, injury mechanism, number of units transfused, and length of stay. RESULTS: Over 7.5 years, 1,813 patients met study criteria. Among patients who received a total of 1 to 2 or 3 to 5 units in the first 24 hours, there was no association between the amount and age of transfused blood and mortality. For patients who received a total of > or = 6 units, the presence of > or = 3 units of young blood was associated with a 3.8-fold increased odds of death (CI: 1.1-12.7), compared with a 7.8-fold (CI: 2.3-26.3) increased odds of death associated with the presence of > or = 3 units of old blood (p = 0.0024). CONCLUSION: Although larger volumes of blood, irrespective of age, are associated with increased odds of mortality, the transfusion of blood stored beyond 2 weeks appears to potentiate this association despite a practice of universal leukoreduction. For patients who receive relatively smaller transfusion volumes, blood age appears to have no effect on mortality.

Closing the open abdomen: improved success with Wittmann Patch staged abdominal closure.

BACKGROUND: Although the "open abdomen" has likely contributed to improved outcomes in trauma patients, the challenge of subsequent fascial closure has emerged. Since mid 2004, we have incorporated Wittmann Patch staged abdominal closure into our management of the open abdomen. The purpose of this study was to evaluate the impact of this device on our incidence of fascial closure versus planned ventral hernia. METHODS: Patients managed by open abdomen from 2001 through 2006 were identified from the trauma registry. Fascial closure immediately after definitive repair of injuries was defined as "early fascial closure." Continuation of the open abdomen beyond the definitive repair of injuries with subsequent fascial closure was defined as "delayed fascial closure." Since April 2004, the Wittmann Patch was uniformly employed in open abdomen management. Patients managed before the use of this device ("pre-Patch") were compared with those managed in the "Patch" era. RESULTS: Fifty-six open abdomens were managed in the pre-Patch era and 103 were managed in the Patch era. In the pre-Patch era, 33 (59%) underwent early fascial closure, compared with 67 (65%) in the Patch era (p NS). For the remaining patients, the incidence of delayed fascial closure was significantly higher in those managed with the Wittmann Patch compared with those managed in the pre-Patch era (78% vs. 30%, p < 0.001). Planned ventral hernia was performed in 8 (8%) patients in the Patch era versus 16 (29%) patients in the pre-Patch era (p < 0.001). Abdominal complications were similar between groups (11% vs. 9%, p NS). CONCLUSIONS: Incorporating the Wittmann Patch into a clinical pathway for management of the open abdomen has contributed to an increased incidence of delayed fascial closure. Abdominal complications were similar in both groups, suggesting that the device is not only efficacious, but also relatively safe.

Body mass index affects the need for and the duration of mechanical ventilation after thoracic trauma.

BACKGROUND: A higher body mass index (BMI) is associated with hypoxia, hypercarbia, and reduced functional residual capacity. The current study evaluates the association between BMI and the need for mechanical ventilation (MV) among patients who have sustained chest trauma. METHODS: Demographic and clinical outcome data were collected from patients suffering blunt or penetrating thoracic traumatic injury admitted to a Level I academic trauma center between January 2001 and June 2006 (n = 3,649). Using logistic regression, the odds of being placed on MV were estimated according to BMI adjusting for the potentially confounding effects of age, mechanism of injury, severity of thoracic, head and overall injury, and pneumonia. RESULTS: Compared with those with a normal BMI (18.5-24.9 kg/m), the odds of MV were not significantly different for underweight (BMI < 18.5 kg/m) patients (odds ratio [OR] 0.98, 95% confidence interval [CI] 0.53-1.80), but were elevated for overweight (BMI 25.0-29.9 kg/m) and obese (BMI 30+ kg/m) patients (OR 1.40, 95% CI 1.08-1.81 and OR 1.53, 95% CI 1.17-1.99, respectively). CONCLUSIONS: Higher BMI values were positively associated with the initiation of MV. Among those patients on MV, an elevated BMI was significantly associated with a longer duration of MV. The field of acute trauma care would benefit from further evaluation of the association between BMI and MV so as to improve ventilation strategies for obese trauma patients.

Echocardiographic correlates are associated with in-hospital mortality in trauma and burn patients.

BACKGROUND: The role of echocardiographic indices of preload and contractility in predicting outcomes is unknown. We report the association of end diastolic area (EDA) and fractional area of change (FAC) with mortality in a cohort of trauma and burn patients. METHODS: Data on 86 patients admitted to a tertiary care center between July 2013 and July 2015 were reviewed. The association between abnormal EDA and FAC and adverse clinical outcomes was tested using exact logistic regression analysis. RESULTS: 31 patients had abnormal EDA (<10 cm2) and 13 had low FAC (<40%). Those with low FAC had higher blood pressure on admission, and lower urine output and higher lactic acid (p= < 0.01) on echocardiography day. Abnormal EDA was associated with in-hospital death (OR 4.20, 95% CI 1.45-12.17). CONCLUSIONS: Echocardiographic measurements can predict outcome in trauma and burn patients. Further studies are needed to confirm these findings.

Gender differences in mortality following burn injury.

Clinical and experimental studies have demonstrated higher mortality following nonthermal trauma among males compared with females. To date, few clinical retrospective studies have focused on gender differences in outcome following burn injury with respect to age. All patients admitted to the University of Alabama at Birmingham (UAB) Burn Center between January 1994 and December 2000 were selected for inclusion in the study. Gender differences in demographic, clinical, and outcome characteristics were compared. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for the association between mortality and gender, both overall and stratified by age. Over the 7-year study period, 1229 males and 382 females were admitted to the UAB Burn Center, and mortality rates were 7.2% and 13.4%, respectively (P = 0.0002). Female patients were more likely to be older, of the black race, and in poorer health. In addition, females were more likely to suffer flame and scald burns. The association between mortality and gender was modified by age. Up to age 60, mortality rates among females were over twice that of males (OR 2.3, 95% Cl 1.4-3.8); however, no difference was noted among those 60 and older (OR 0.9, 95% Cl 0.5-1.6). These associations persisted following adjustment for potentially confounding variables. Causes and timing of death were similar for males and females. Women less than 60 years of age who sustain burn injuries have an increased risk of death compared with males. Differences in the natural history of nonthermal trauma and burn injury may provide insight regarding these divergent findings.

A 100% departmental mortality review improves observed-to-expected mortality ratios and University HealthSystem Consortium rankings.

BACKGROUND: Public reporting of mortality, Patient Safety Indicators (PSI) and hospital-acquired conditions (HACs) is the reality of quality measurement. A review of our department's data identified opportunities for improvement. We began a surgeon-led 100% review of mortality, PSIs, and HACs to improve patient care and surgeon awareness of these metrics. STUDY DESIGN: From December 2012 through August 2013, there were 11,899 patients cared for on 12 surgical services. A surgeon from each service led monthly reviews of all mortality, PSIs, or HACs with central reporting of preventability and coding accuracy. We compared the University HealthSystem Consortium observed-to-expected (OE) mortality ratios (mean <1 fewer observed than expected deaths) and University HealthSystem Consortium relative rankings (lower number is better) before and after implementation. Statistical significance was p < 0.05 by Poisson regression. RESULTS: Of the 11,899 patients in the study period, there were 235 deaths, 290 PSIs, and 26 HACs identified and reviewed. The most common PSIs were postoperative deep vein thrombosis/pulmonary thromboembolism (n = 75), respiratory failure (n = 61), hemorrhage/hematoma (n = 33), and accidental puncture/laceration (n = 33). Before December 20, 2012, the OE ratio for mortality was consistently >1, then fell and remained <1 during the study period (p < 0.05). The OE mortality ratio in the fourth quarter of 2012 was 1.14 and fell to 0.88, 0.91, and 0.75 in the first, second, and third quarters of calendar year 2013 (p < 0.05). The overall Inpatient Quality Indicators #90 (composite postoperative mortality rank) rankings increased from 109 of 118 in the third quarter of 2012 to 47 of 119 in the third quarter of 2013. CONCLUSIONS: A surgeon-led systematic review of mortality, PSIs, and HACs improved our OE ratio and University HealthSystem Consortium postsurgical relative rankings. Surgeon engagement and ownership is critical for success.

Effectiveness of an early mobilization protocol in a trauma and burns intensive care unit: a retrospective cohort study.

BACKGROUND: Bed rest and immobility in patients on mechanical ventilation or in an intensive care unit (ICU) have detrimental effects. Studies in medical ICUs show that early mobilization is safe, does not increase costs, and can be associated with decreased ICU and hospital lengths of stay (LOS). OBJECTIVE: The purpose of this study was to assess the effects of an early mobilization protocol on complication rates, ventilator days, and ICU and hospital LOS for patients admitted to a trauma and burn ICU (TBICU). DESIGN: This was a retrospective cohort study of an interdisciplinary quality-improvement program. METHODS: Pre- and post-early mobility program patient data from the trauma registry for 2,176 patients admitted to the TBICU between May 2008 and April 2010 were compared. RESULTS: No adverse events were reported related to the early mobility program. After adjusting for age and injury severity, there was a decrease in airway, pulmonary, and vascular complications (including pneumonia and deep vein thrombosis) post-early mobility program. Ventilator days and TBICU and hospital lengths of stay were not significantly decreased. LIMITATIONS: Using a historical control group, there was no way to account for other changes in patient care that may have occurred between the 2 periods that could have affected patient outcomes. The dose of physical activity both before and after the early mobility program were not specifically assessed. CONCLUSIONS: Early mobilization of patients in a TBICU was safe and effective. Medical, nursing, and physical therapy staff, as well as hospital administrators, have embraced the new culture of early mobilization in the ICU.
