Inter-Hospital Transfer Is an Independent Risk Factor for Hospital-Associated Infection.

Background: Regionalization of surgical care shifts higher acuity patients to larger centers. Hospital-associated infections (HAIs) are important quality measures with financial implications. In our ongoing efforts to eliminate HAIs, we examined the potential role for inter-hospital transfer in our cases of HAI across a multihospital system. Hypothesis: Surgical patients transferred to a regional multihospital system have a higher risk of National Healthcare Safety Network (NHSN)-labeled HAIs. Patients and Methods: The analysis cohort of adult surgical inpatients was filtered from a five-hospital health system administration registry containing encounters from 2014 to 2021. The dataset contained demographics, health characteristics, and acuity variables, along with the NHSN defined HAIs of central line-associated blood stream infection (CLABSI), catheter-associated urinary tract infection (CAUTI), and Clostridioides difficile infection (CDI). Univariable and multivariable statistics were performed. Results: The surgical cohort identified 92,832 patients of whom 3,232 (3.5%) were transfers. The overall HAI rate was 0.6% (528): 86 (0.09%) CLABSI, 133 (0.14%) CAUTI, and 325 (0.35%) CDI. Across the three HAIs, the rate was higher in transfer patients compared with non-transfer patients (CLABSI: n = 18 (1.3%); odds ratio [OR], 4.79; CAUTI: n = 25 (1.8%); OR, 4.20; CDI: n = 37 (1.1%); OR, 3.59); p < 0.001 for all. Multivariable analysis found transfer patients had an increased rate of HAIs (OR, 1.56; p < 0.001). Conclusions: There is an increased risk-adjusted rate of HAIs in transferred surgical patients as reflected in the NHSN metrics. This phenomenon places a burden on regional centers that accept high-risk surgical transfers, in part because of the downstream effects of healthcare reimbursement programs.

Shifts in Attitudes and Intentions to Practice Following Medication-Assisted Treatment Training.

PURPOSE: The Idaho State University Physician Assistant (PA) program was one of the first PA programs in the country to incorporate medication-assisted treatment (MAT) into its curriculum. This manuscript documents the impact of the course. METHODS: In the spring and summer of 2018, 61 students and 12 local providers enrolled in an elective MAT course developed by Idaho State University. All completed the training. At the end of the course, only the students submitted reflective essays. RESULTS: A review and coding of the essays indicated that MAT education increased knowledge about addiction and resulted in self-reported decreases in negative attitudes towards people with addictions. CONCLUSION: PA programs can support communities' increased capacity to offer MAT. A widely available course appears to result in important gains in both knowledge and attitude.

The Effect of Antithrombotics on Hematoma Expansion in Small- to Moderate-Sized Traumatic Intraparenchymal Hemorrhages.

BACKGROUND: Although pre-injury antithrombotic agents, including antiplatelets and anticoagulants, are historically associated with expansion of traumatic intraparenchymal hemorrhage (tIPH), the literature has poorly elucidated the actual risk of hematoma expansion on repeat computed tomography (CT). The objective was to determine the effect of antithrombotic agents on hematoma expansion in tIPH by comparing patients with and without pre-injury antithrombotic medication. METHODS: The volume of all tIPHs over a 5-year period at an academic Level 1 trauma center was measured retrospectively. The initial tIPH was divided into 3 equally sized quantiles. The third tercile, representing the largest subset of tIPH, was then removed from the study population because these patients reflect a different pathophysiologic mechanism that may require a more acute and aggressive level of care with reversal agents and/or operative management. Per institutional policy, all patients with small- to moderate-sized hemorrhages received a 24-hour stability CT scan. Patients who received reversal agents were excluded. RESULTS: Of the 105 patients with a tIPH on the initial head CT scan, small- to moderate-sized hemorrhages were <5 cm3. The size of tIPH on initial imaging did not statistically significantly differ between the antithrombotic cohort (0.7 ± 0.1 cm3) and the non-antithrombotic cohort (0.5 ± 0.1 cm3) (P = 0.091). Similarly, the volume of tIPH failed to differ on 24-hour repeat imaging (1.0 ± 0.2 cm3 vs. 0.6 ± 0.1 cm3, respectively, P = 0.172). Following a multiple linear regression, only history of stroke, not antithrombotic medications, predicted increased tIPH on 24-hour repeat imaging. CONCLUSIONS: In small- to moderate-sized tIPH, withholding antithrombotic agents without reversal may be sufficient.

Necrotizing pancreatitis: A review for the acute care surgeon.

BACKGROUND: Necrotizing pancreatitis is a common condition with high mortality; the acute care surgeon is frequently consulted for management recommendations. Furthermore, there has been substantial change in the timing, approach, and frequency of surgical intervention for this group of patients. METHODS: In this article we summarize key clinical and research developments regarding necrotizing pancreatitis, including current recommendations for treatment of patients requiring intensive care and those with common complications. Articles from all years were considered to provide proper historical context, and most recent management recommendations are identified. RESULTS: Epidemiology, diagnosis, treatment in the acute phase, and complications (both short-term and long-term) are discussed. Images of surgical interventions are included from our institutional experience. CONCLUSION: Necrotizing pancreatitis management remains heavily based on clinical judgement, although technological advances and clinical trials have made decision making more straightforward.

Rib fractures in the elderly: physiology trumps anatomy.

INTRODUCTION: Rib fractures in elderly patients are associated with increased morbidity and mortality. Predicting which patients are at risk for complications is an area of debate. Current models use anatomic, physiologic or laboratory parameters in isolation to answer this question. The 'RibScore' is an anatomic model that assesses fracture severity. Given that frailty is a major driver of adverse outcomes in the elderly, we hypothesize that the combined analysis of fracture severity, physiologic reserve and current pulmonary function are better predictors of respiratory compromise in this population. METHODS: This is a retrospective chart review of 263 trauma patients age ≥55 from January 2014 to June 2017. Criteria included blunt mechanism and ≥ 1 rib fracture identified by CT. Variables indicating adverse pulmonary outcomes were defined by: pneumonia, respiratory failure and tracheostomy. Three models were assessed: (1) RibScore, (2) Modified Frailty Index (mFI) and (3) initial partial pressure of carbondioxide (PaCO2). RESULTS: A total of 263 patients met inclusion criteria. 13% developed pulmonary complications. Increased RibScore, mFI and PaCO2 were each statistically associated with risk of complications. Receiver operating characteristics area under the curve analysis of individual models predicted complications with the following concordance statistic (CS): anatomic (RibScore) yielded a CS of 0.79 (95% CI 0.69 to 0.89); physiologic (mFI) yielded a CS of 0.83 (95% CI 0.75 to 0.91) and laboratory (PaCO2) yielded a CS of 0.88 (95% CI 0.80 to 0.95). The PaCO2 had the highest discriminative ability of the three individual models. Combining all three models yielded the best performance with a CS of 0.90 (95% CI 0.81 to 0.97). DISCUSSION: The RibScore maintains discriminative ability in the elderly. However, models based on mFI and PaCO2 individually outperform the RibScore. A combination of all three models yields the highest discriminative ability. This combined approach is best for assessing the severity of rib fractures and prediction of complications in the elderly. LEVEL OF EVIDENCE: Prognostic Study, Level III.

Hyperglycemic Hyperosmolar State During Induction Chemotherapy for Acute Lymphoblastic Leukemia.

We present the case of a 16-year-old boy who presented with fatigue, polyuria, and polydipsia while on chemotherapy for his relapsed acute lymphoblastic leukemia (ALL). Blood gas examination confirmed the diagnosis of hyperosmolar hyperglycemic state. The etiology for his hyperglycemia was most likely a result of oral glucocorticoid therapy combined with asparaginase therapy-both are a cornerstone of induction chemotherapy for ALL. The patient was aggressively rehydrated with saline, and medications were administered to correct his hyperkalemia. He was then slowly brought to euglycemia with a continuous infusion of insulin. Although hyperosmolar hyperglycemic state is rare during the treatment of ALL, frontline providers should be aware of this diagnosis because of the significant risk of hypovolemic shock and death if correction of hyperglycemia occurs prior to complete fluid resuscitation.

Preperitoneal pelvic packing reduces mortality in patients with life-threatening hemorrhage due to unstable pelvic fractures.

BACKGROUND: A 2015 American Association for the Surgery of Trauma trial reported a 32% mortality for pelvic fracture patients in shock. Angioembolization (AE) is the most common intervention; the Maryland group revealed time to AE averaged 5 hours. The goal of this study was to evaluate the time to intervention and outcomes of an alternative approach for pelvic hemorrhage. We hypothesized that preperitoneal pelvic packing (PPP) results in a shorter time to intervention and lower mortality. METHODS: In 2004, we initiated a PPP protocol for pelvic fracture hemorrhage. RESULTS: During the 11-year study, 2,293 patients were admitted with pelvic fractures; 128 (6%) patients underwent PPP (mean age, 44 ± 2 years; Injury Severity Score (ISS), 48 ± 1.2). The lowest emergency department systolic blood pressure was 74 mm Hg and highest heart rate was 120. Median time to operation was 44 minutes and 3 additional operations were performed in 109 (85%) patients. Median RBC transfusions before SICU admission compared with the 24 postoperative hours were 8 versus 3 units (p < 0.05). After PPP, 16 (13%) patients underwent AE with a documented arterial blush.Mortality in this high-risk group was 21%. Death was due to brain injury (9), multiple organ failure (4), pulmonary or cardiac failure (6), withdrawal of support (4), adverse physiology (3), and Mucor infection (1). Of those patients with physiologic exhaustion, 2 died in the operating room at 89 and 100 minutes after arrival, whereas 1 died 9 hours after arrival. CONCLUSIONS: PPP results in a shorter time to intervention and lower mortality compared with modern series using AE. Examining mortality, only 3 (2%) deaths were attributed to the immediate sequelae of bleeding with physiologic failure. With time to death under 100 minutes in 2 patients, AE is unlikely to have been feasible. PPP should be used for pelvic fracture-related bleeding in the patient who remains unstable despite initial transfusion. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Expanded screening criteria for blunt cerebrovascular injury: a bigger impact than anticipated.

BACKGROUND: We implemented expanded screening criteria for blunt cerebrovascular injuries (BCVIs) in an attempt to capture the remaining 20% of patients not historically identified with earlier protocols. We hypothesized that these expanded criteria would capture the additional 20% of BCVI patients not previously identified. METHODS: Screening criteria for BCVI were expanded in 2011 after identifying new injury patterns. The study population included 4 years prior (2007 to 2010; classic) and following (2011 to 2014; expanded) implementation of expanded criteria. RESULTS: BCVIs were identified in 386 patients: 150 during the classic period (2.36% incidence) and 236 in the expanded period (2.99% incidence). In the expanded period, 155 patients were imaged based on classic screening criteria, 62 on expanded criteria (21 complex skull fractures, 20 upper rib fractures, 6 mandible fractures, 2 scalp degloving, 1 great vessel injury, and 12 combination), and 19 for other injuries and symptoms. CONCLUSIONS: There was a significant increase in the identification of BCVI following the adoption of expanded screening criteria, resulting in a substantial reduction of missed injuries. Expanded criteria should be adopted when screening for BCVI.

Goal-directed Hemostatic Resuscitation of Trauma-induced Coagulopathy: A Pragmatic Randomized Clinical Trial Comparing a Viscoelastic Assay to Conventional Coagulation Assays.

BACKGROUND: Massive transfusion protocols (MTPs) have become standard of care in the management of bleeding injured patients, yet strategies to guide them vary widely. We conducted a pragmatic, randomized clinical trial (RCT) to test the hypothesis that an MTP goal directed by the viscoelastic assay thrombelastography (TEG) improves survival compared with an MTP guided by conventional coagulation assays (CCA). METHODS: This RCT enrolled injured patients from an academic level-1 trauma center meeting criteria for MTP activation. Upon MTP activation, patients were randomized to be managed either by an MTP goal directed by TEG or by CCA (ie, international normalized ratio, fibrinogen, platelet count). Primary outcome was 28-day survival. RESULTS: One hundred eleven patients were included in an intent-to-treat analysis (TEG = 56, CCA = 55). Survival in the TEG group was significantly higher than the CCA group (log-rank P = 0.032, Wilcoxon P = 0.027); 20 deaths in the CCA group (36.4%) compared with 11 in the TEG group (19.6%) (P = 0.049). Most deaths occurred within the first 6 hours from arrival (21.8% CCA group vs 7.1% TEG group) (P = 0.032). CCA patients required similar number of red blood cell units as the TEG patients [CCA: 5.0 (2-11), TEG: 4.5 (2-8)] (P = 0.317), but more plasma units [CCA: 2.0 (0-4), TEG: 0.0 (0-3)] (P = 0.022), and more platelets units [CCA: 0.0 (0-1), TEG: 0.0 (0-0)] (P = 0.041) in the first 2 hours of resuscitation. CONCLUSIONS: Utilization of a goal-directed, TEG-guided MTP to resuscitate severely injured patients improves survival compared with an MTP guided by CCA and utilizes less plasma and platelet transfusions during the early phase of resuscitation.

Clinical Utility of Chest Computed Tomography in Patients with Rib Fractures CT Chest and Rib Fractures.

BACKGROUND: Chest CT is more sensitive than a chest X-ray (CXR) in diagnosing rib fractures; however, the clinical significance of these fractures remains unclear. OBJECTIVES: The purpose of this study was to determine the added diagnostic use of chest CT performed after CXR in patients with either known or suspected rib fractures secondary to blunt trauma. METHODS: Retrospective cohort study of blunt trauma patients with rib fractures at a level I trauma center that had both a CXR and a CT chest. The CT finding of ≥ 3 additional fractures in patients with ≤ 3 rib fractures on CXR was considered clinically meaningful. Student's t-test and chi-square analysis were used for comparison. RESULTS: We identified 499 patients with rib fractures: 93 (18.6%) had CXR only, 7 (1.4%) had chest CT only, and 399 (79.9%) had both CXR and chest CT. Among these 399 patients, a total of 1,969 rib fractures were identified: 1,467 (74.5%) were missed by CXR. The median number of additional fractures identified by CT was 3 (range, 4 - 15). Of 212 (53.1%) patients with a clinically meaningful increase in the number of fractures, 68 patients underwent one or more clinical interventions: 36 SICU admissions, 20 pain catheter placements, 23 epidural placements, and 3 SSRF. Additionally, 70 patients had a chest tube placed for retained hemothorax or occult pneumothorax. Overall, 138 patients (34.5%) had a change in clinical management based upon CT chest. CONCLUSIONS: The chest X-ray missed ~75% of rib fractures seen on chest CT. Although patients with a clinical meaningful increase in the number of rib fractures were more likely to be admitted to the intensive care unit, there was no associated improvement in pulmonary outcomes.

A prospective, controlled clinical evaluation of surgical stabilization of severe rib fractures.

BACKGROUND: Previous studies of surgical stabilization of rib fractures (SSRF) have been limited by small sample sizes, retrospective methodology, and inclusion of only patients with flail chest. We performed a prospective, controlled evaluation of SSRF as compared with optimal medical management for severe rib fracture patterns among critically ill trauma patients. We hypothesized that SSRF improves acute outcomes. METHODS: We conducted a 2-year clinical evaluation of patients with any of the following rib fracture patterns: flail chest, three or more fractures with bicortical displacement, 30% or greater hemithorax volume loss, and either severe pain or respiratory failure despite optimal medical management. In the year 2013, all patients were managed nonoperatively. In the year 2014, all patients were managed operatively. Outcomes included respiratory failure, tracheostomy, pneumonia, ventilator days, tracheostomy, length of stay, daily maximum incentive spirometer volume, narcotic requirements, and mortality. Univariate and multivariable analyses were performed. RESULTS: Seventy patients were included, 35 in each group. For the operative group, time from injury to surgery was 2.4 day, operative time was 1.5 hours, and the ratio of ribs fixed to ribs fractured was 0.6. The operative group had a significantly higher RibScore (4 vs. 3, respectively, p < 0.01) and a significantly lower incidence of intracranial hemorrhage (5.7% vs. 28.6%, respectively, p = 0.01). After controlling for these differences, the operative group had a significantly lower likelihood of both respiratory failure (odds ratio, 0.24; 95% confidence interval, 0.06-0.93; p = 0.03) and tracheostomy (odds ratio, 0.18; 95% confidence interval, 0.04-0.78; p = 0.03). Duration of ventilation was significantly lower in the operative group (p < 0.01). The median daily spirometry value was 250 mL higher in the operative group (p = 0.04). Narcotic requirements were comparable between groups. There were no mortalities. CONCLUSION: In this evaluation, SSRF as compared with the best medical management improved acute outcomes among a group of critically ill trauma patients with a variety of severe fracture patterns. LEVEL OF EVIDENCE: Therapeutic study, level II.

Screening for Ventilator-Associated Pneumonia in the Surgical Intensive Care Unit: A Single-Institution Analysis of 1,013 Lower Respiratory Tract Cultures.

BACKGROUND: Refinement of criteria for both screening and initiation of empiric therapy in ventilator-associated pneumonia (VAP) will minimize antibiotic overuse. We hypothesized that variables within the commonly used Clinical Pulmonary Infection Score (CPIS) have unfavorable test performance characteristics. METHODS: Consecutive bronchoalveolar lavage (BAL) cultures obtained from surgical intensive care unit patients were abstracted (2009-2012). Ventilator-associated pneumonia was defined as ≥10(5) cfu/mL. The CPIS both without (CPISclinical) and with (CPISclinical+GS) the result of gram stain (GS) was calculated. Test performance characteristics for the sample, as well as several subgroups, were compared. RESULTS: One thousand thirteen lower respiratory tract cultures from 492 patients were analyzed; 438 (43.2%) of cultures were classified as VAP, and 310 of 492 patients (62.4%) had ≥1 episode of VAP. Both CPISclinical and CPISclinical+GS had poor discrimination for VAP (Receiver-operating characteristic area under the curve=0.55 and 0.66, respectively). Sensitivity of CPISclinical using a threshold of >6 was 21%; the lowest threshold for CPISclinical for which the sensitivity was at least 85% was 3. The highest sensitivity among the individual CPIS components was new CXR infiltrate (91.1%). Among the subset of cultures sent during the early VAP window (days intubated 2-5), organisms on GS had a sensitivity of 93.3%. The CPISclinical, CPISclinical+GS, organisms, and neutrophils on GS parameters all became less accurate in both the late VAP window and when screening for recurrent VAP. Every case of VAP had at least one of the following: 1) fever; 2) new CXR infiltrate, or 3) organisms on GS. CONCLUSION: In this series of BALs, traditional screening tools for VAP missed the majority of microbiological confirmed cases. Screening based on either new CXR infiltrate or fever yielded an acceptably high sensitivity. The only scenario identified in which empiric antibiotics could be withheld safely was the absence of organisms on GS in the early VAP window.

White matter disruption in moderate/severe pediatric traumatic brain injury: advanced tract-based analyses.

Traumatic brain injury (TBI) is the leading cause of death and disability in children and can lead to a wide range of impairments. Brain imaging methods such as DTI (diffusion tensor imaging) are uniquely sensitive to the white matter (WM) damage that is common in TBI. However, higher-level analyses using tractography are complicated by the damage and decreased FA (fractional anisotropy) characteristic of TBI, which can result in premature tract endings. We used the newly developed autoMATE (automated multi-atlas tract extraction) method to identify differences in WM integrity. 63 pediatric patients aged 8-19 years with moderate/severe TBI were examined with cross sectional scanning at one or two time points after injury: a post-acute assessment 1-5 months post-injury and a chronic assessment 13-19 months post-injury. A battery of cognitive function tests was performed in the same time periods. 56 children were examined in the first phase, 28 TBI patients and 28 healthy controls. In the second phase 34 children were studied, 17 TBI patients and 17 controls (27 participants completed both post-acute and chronic phases). We did not find any significant group differences in the post-acute phase. Chronically, we found extensive group differences, mainly for mean and radial diffusivity (MD and RD). In the chronic phase, we found higher MD and RD across a wide range of WM. Additionally, we found correlations between these WM integrity measures and cognitive deficits. This suggests a distributed pattern of WM disruption that continues over the first year following a TBI in children.

Predictors of the necessity for early tracheostomy in patients with acute cervical spinal cord injury: a 15-year experience.

BACKGROUND: The need for mechanical ventilation (MV) after spinal cord injury (SCI) is a risk factor for prolonged critical care. The "purpose" of this study was to identify the level of cervical SCI that requires MV, thereby defining candidates for tracheostomy. METHODS: Patients with cervical SCI over a 15-year period were reviewed. RESULTS: One hundred sixty-three patients sustained cervical SCI. Of 76 complete injuries, 91% required MV for greater than 48 hours. By injury level, MV incidence was 100% for C2-4, 91% for C5, 79% for C6, and 80% for C7. Only one quarter of patients with incomplete SCI required MV for greater than 48 hours; Glascow Coma Score and Injury Severity Score were significantly worse compared with patients not requiring MV. CONCLUSIONS: Factors influencing the decision for tracheostomy in cervical SCI patients include the presence of a complete SCI, anatomic level of injury, Glascow Coma Score, Injury Severity Score, and associated thoracic injury. Patients with complete cervical SCI often require prolonged MV. Conversely, the minority of incomplete SCI required MV; the need for tracheostomy was likely performed for associated injuries. Utilizing identified factors permits a thoughtful approach to tracheostomy in this patient population.

Intra-abdominal injury following blunt trauma becomes clinically apparent within 9 hours.

BACKGROUND: The diagnosis of blunt abdominal trauma can be challenging and resource intensive. Observation with serial clinical assessments plays a major role in the evaluation of these patients, but the time required for intra-abdominal injury to become clinically apparent is unknown. The purpose of this study was to determine the amount of time required for an intra-abdominal injury to become clinically apparent after blunt abdominal trauma via physical examination or commonly followed clinical values. METHODS: A retrospective review of patients who sustained blunt trauma resulting in intra-abdominal injury between June 2010 and June 2012 at a Level 1 academic trauma center was performed. Patient demographics, injuries, and the amount of time from emergency department admission to sign or symptom development and subsequent diagnosis were recorded. All diagnoses were made by computed tomography or at the time of surgery. Patient transfers from other hospitals were excluded. RESULTS: Of 3,574 blunt trauma patients admitted to the hospital, 285 (8%) experienced intra-abdominal injuries. The mean (SD) age was 36 (17) years, the majority were male (194 patients, 68%) and the mean (SD) Injury Severity Score (ISS) was 21 (14). The mean (SD) time from admission to diagnosis via computed tomography or surgery was 74 (55) minutes. Eighty patients (28%) required either surgery (78 patients, 17%) or radiographic embolization (2 patients, 0.7%) for their injury. All patients who required intervention demonstrated a sign or symptom of their intra-abdominal injury within 60 minutes of arrival, although two patients were intervened upon in a delayed fashion. All patients with a blunt intra-abdominal injury manifested a clinical sign or symptom of their intra-abdominal injury, resulting in their diagnosis within 8 hours 25 minutes of arrival to the hospital. CONCLUSION: All diagnosed intra-abdominal injuries from blunt trauma manifested clinical signs or symptoms that could prompt imaging or intervention, leading to their diagnosis within 8 hours 25 minutes of arrival to the hospital. All patients who required an intervention for their injury manifested a sign or symptom of their injury within 60 minutes of arrival. LEVEL OF EVIDENCE: Therapeutic study, level IV. Epidemiologic study, level III.

Temporal trends of postinjury multiple-organ failure: still resource intensive, morbid, and lethal.

BACKGROUND: While the incidence of postinjury multiple-organ failure (MOF) has declined during the past decade, temporal trends of its morbidity, mortality, presentation patterns, and health care resources use have been inconsistent. The purpose of this study was to describe the evolving epidemiology of postinjury MOF from 2003 to 2010 in multiple trauma centers sharing standard treatment protocols. METHODS: "Inflammation and Host Response to Injury Collaborative Program" institutions that enrolled more than 20 eligible patients per biennial during the 2003 to 2010 study period were included. The patients were aged 16 years to 90 years, sustained blunt torso trauma with hemorrhagic shock (systolic blood pressure < 90 mm Hg, base deficit ≥ 6 mEq/L, blood transfusion within the first 12 hours), but without severe head injury (motor Glasgow Coma Scale [GCS] score < 4). MOF temporal trends (Denver MOF score > 3) were adjusted for admission risk factors (age, sex, body max index, Injury Severity Score [ISS], systolic blood pressure, and base deficit) using survival analysis. RESULTS: A total of 1,643 patients from four institutions were evaluated. MOF incidence decreased over time (from 17% in 2003-2004 to 9.8% in 2009-2010). MOF-related death rate (33% in 2003-2004 to 36% in 2009-2010), intensive care unit stay, and mechanical ventilation duration did not change over the study period. Adjustment for admission risk factors confirmed the crude trends. MOF patients required much longer ventilation and intensive care unit stay, compared with non-MOF patients. Most of the MOF-related deaths occurred within 2 days of the MOF diagnosis. Lung and cardiac dysfunctions became less frequent (57.6% to 50.8%, 20.9% to 12.5%, respectively), but kidney and liver failure rates did not change (10.1% to 12.5%, 15.2% to 14.1%). CONCLUSION: Postinjury MOF remains a resource-intensive, morbid, and lethal condition. Lung injury is an enduring challenge and should be a research priority. The lack of outcome improvements suggests that reversing MOF is difficult and prevention is still the best strategy. LEVEL OF EVIDENCE: Epidemiologic study, level III.
