RESUMO
BACKGROUND: Hospital readmissions are considered to be a measure of quality of care, correlate with worse outcomes, and may soon lead to decreased reimbursement. The comorbidity-polypharmacy score (CPS) is the sum of the number of preinjury medications and comorbidities, and may estimate patient frailty more effectively than patient age. This study evaluates the association between CPS and readmission. METHODS: Medical records for trauma patients ≥45 y evaluated between January 1 and December 31, 2008, at our American College of Surgeons-verified level 1 trauma center were reviewed to obtain information on demographics, injuries, preinjury comorbidities, and medications, and occurrences of readmission to our facility within 30 d of discharge. Chi-square and Kruskal-Wallis testing was used to evaluate differences between readmitted and nonreadmitted patients, with multiple logistic regression used to evaluate the contribution of independent risk factors for readmission. RESULTS: A total of 879 patients were included; their ages ranged from 45-103 y (median 58), injury severity scores from 0-50 y (median 5), and CPS from 0-39 y (median 7). A total of 76 patients (8.6%) were readmitted to our facility within 30 d of discharge. The readmitted cohort had higher CPS (median, 9.5, range 0-32, P = 0.031) and injury severity score (median, 9, range 1-38, P = 0.045), but no difference in age (median, 59.5, range 47-99, P = 0.646). Logistic regression demonstrated independent association of higher CPS with increased risk of readmission, with each CPS point increasing readmission likelihood by 3.5% (P = 0.03). CONCLUSIONS: CPS appears to correlate well with readmissions within 30 d. Frailty defined by CPS was a significantly stronger predictor of readmission than was patient age. Early recognition of elevated CPS may improve discharge planning and help guide interventions to decrease readmission rates in older trauma patients.

BACKGROUND: Following the 2009 H1N1 Influenza pandemic, extracorporeal membrane oxygenation (ECMO) emerged as a viable alternative in selected, severe cases of ARDS. Acute Respiratory Distress Syndrome (ARDS) is a major public health problem. Average medical costs for ARDS survivors on an annual basis are multiple times those dedicated to a healthy individual. Advances in medical and ventilatory management of severe lung injury and ARDS have improved outcomes in some patients, but these advances fail to consistently "rescue" a significant proportion of those affected. DISCUSSION: Here we present a synopsis of the challenges, considerations, and potential controversies regarding veno-venous ECMO that will be of benefit to anesthesiologists, surgeons, and intensivists, especially those newly confronted with care of the ECMO patient. We outline a number of points related to ECMO, particularly regarding cannulation, pump/oxygenator design, anticoagulation, and intravascular fluid management of patients. We then address these challenges/considerations/controversies in the context of their potential future implications on clinical approaches to ECMO patients, focusing on the development and advancement of standardized ECMO clinical practices. SUMMARY: Since the 2009 H1N1 pandemic ECMO has gained a wider acceptance. There are challenges that still must be overcome. Further investigations of the benefits and effects of ECMO need to be undertaken in order to facilitate the implementation of this technology on a larger scale.

BACKGROUND: Intentional ingestion of foreign objects (IIFO) is common in the incarcerated population. This study was undertaken in order to better define clinical patterns of IIFO among prisoners. We sought to determine factors associated with the need for endoscopic and surgical therapy for IIFO. METHODS: After obtaining permission to conduct IIFO research in incarcerated populations, study patients were identified by ICD-9 codes. Patient charts were reviewed for demographics; past medical history; IIFO characteristics; and diagnostic, endoscopic, and surgical findings. Univariate and multivariate analyses were performed using statistical software. RESULTS: Thirty patients with 141 episodes of IIFO were identified. The mean number of ingested items per episode was 4.60. Endoscopy was performed in 97 of 141 IIFO instances, with failure to retrieve the ingested object in 21 of 97 cases (22%). Eleven instances (7.8%) required surgical intervention. On multivariate analyses, hospital admission was associated with elevated white blood cell count (odds ratio [OR] 1.4, P < 0.05) and number of items ingested (OR 1.3, P < 0.05). The need for endoscopy was independently associated with ingestion of multiple objects (OR 3.3, P < 0.05) and elevated white blood cell count (OR 1.3, P < 0.05). Surgical therapy was significantly associated with elevated white blood cell count (OR 1.6, P < 0.01) and with increasing number of ingested items (OR 1.07 per item, P < 0.05). Endoscopy is associated with significantly lower odds of surgery (OR 0.13, P < 0.01). CONCLUSIONS: Intentional ingestion of foreign objects continues to pose a significant human and economic burden. The need for admission or therapy is frequently associated with leukocytosis. Further investigation is warranted into resource-appropriate triage of patients who present with IIFO.

BACKGROUND: Traditional methods for intravascular volume status assessment are invasive and are associated significant complications. While focused bedside sonography of the inferior vena cava (IVC) has been shown to be useful in estimating intravascular volume status, it may be technically difficult and limited by patient factors such as obesity, bowel gas, or postoperative surgical dressings. The goal of this investigation is to determine the feasibility of subclavian vein (SCV) collapsibility as an adjunct to IVC collapsibility in intravascular volume status assessment. METHODS: A prospective study was conducted on a convenience sample of surgical intensive care unit patients to evaluate interchangeability of IVC collapsibility index (IVC-CI) and SCV-CI. After demographic and acuity of illness information was collected, all patients underwent serial, paired assessments of IVC-CI and SCV-CI using portable ultrasound device (M-Turbo; Sonosite, Bothell, WA). Vein collapsibility was calculated using the formula [collapsibility (%) = (max diameter - min diameter)/max diameter × 100%]. Paired measurements from each method were compared using correlation coefficient and Bland-Altman measurement bias analysis. RESULTS: Thirty-four patients (mean age 56 y, 38% female) underwent a total of 94 paired SCV-CI and IVC-CI sonographic measurements. Mean acute physiology and chronic health evaluation II score was 12. Paired SCV- and IVC-CI showed acceptable correlation (R(2) = 0.61, P < 0.01) with acceptable overall measurement bias [Bland-Altman mean collapsibility difference (IVC-CI minus SCV-CI) of -3.2%]. In addition, time needed to acquire and measure venous diameters was shorter for the SCV-CI (70 s) when compared to IVC-CI (99 s, P < 0.02). CONCLUSIONS: SCV collapsibility assessment appears to be a reasonable adjunct to IVC-CI in the surgical intensive care unit patient population. The correlation between the two techniques is acceptable and the overall measurement bias is low. In addition, SCV-CI measurements took less time to acquire than IVC-CI measurements, although the clinical relevance of the measured time difference is unclear.

OBJECTIVE: Post-emergency department triage of older trauma patients continues to be challenging, as morbidity and mortality for any given level of injury severity tend to increase with age. The comorbidity-polypharmacy score (CPS) combines the number of pre-injury medications with the number of comorbidities to estimate the severity of comorbid conditions. This retrospective study examines the relationship between CPS and triage accuracy for older (≥45y) patients admitted for traumatic injury. METHODS: Patients aged 45y and older presenting to level 1 trauma center from 2005 to 2008 were included. Basic data included patient demographics, injury severity score, morbidity and mortality, and functional outcome measures. CPS was calculated by adding total numbers of comorbid conditions and pre-injury medications. Patients were divided into three triage groups: undertriage (UT), appropriate triage (AT), and overtriage (OT). UT criteria included initial admission to the floor or step-down unit followed by an unplanned transfer to intensive care unit (ICU) within 24h of admission. OT was defined as initial ICU admission for <1d without stated need for ICU level of care (i.e., lack of evidence for tracheal intubation or mechanical ventilation, injury-related hemorrhage, or other traditional ICU indications, such as intracranial bleeding). All other patients were presumed to be correctly triaged. The three triage groups were then analyzed looking for contributors to mistriage. RESULTS: Charts for 711 patients were evaluated (mean age, 63.5y; 55.7% male; mean ISS, 9.02). Of those, 11 (1.55%) met criteria for UT and 14 (1.97%) for OT. The remaining 686 patients had no evidence of mistriage. The three groups were similar in terms of injury severity and GCS. The groups were significantly different with respect to CPS, with UT CPSs (14.9±6.80) being nearly three times higher than OT CPSs (5.14±3.48). There were more similarities between AT and OT groups, with the UT group being characterized by greater number of complications and lower functional outcomes at discharge (all, P<0.05). The UT group had significantly higher mortality (27%) than the AT and OT groups (6% and 0%, respectively). CONCLUSIONS: In the era of medication reconciliation, CPS is easy to obtain and calculate in patients who are not critically injured. This study suggests that CPS may be a promising adjunct in identifying older trauma patients who are more likely to be undertriaged. The significance of our findings is especially important when considering that injury severity in the UT group was similar to that in the other groups. Further evaluation of CPS as a triage tool in acute trauma is warranted.

Nonoperative management of both blunt and penetrating injuries can be challenging. During the past three decades, there has been a major shift from operative to increasingly nonoperative management of traumatic injuries. Greater reliance on nonoperative, or "conservative" management of abdominal solid organ injuries is facilitated by the various sophisticated and highly accurate noninvasive imaging modalities at the trauma surgeon's disposal. This review discusses selected topics in nonoperative management of both blunt and penetrating trauma. Potential complications and pitfalls of nonoperative management are discussed. Adjunctive interventional therapies used in treatment of nonoperative management-related complications are also discussed. REPUBLISHED WITH PERMISSION FROM: Stawicki SPA.

RESUMO
Integrated, multidisciplinary team approach to the multiply injured patient can help optimize care, minimize morbidity, and reduce mortality. It also provides a framework for accelerated postinjury rehabilitation course. The characteristics and potential benefits of this approach, including team dynamics and interactions, are discussed in this brief review. Emphasis is placed on synergies provided by specialty teams working together in the framework of care coordination, timing of surgical and nonsurgical interventions, and injury/physiologic considerations.

RESUMO
There is substantial evidence indicating that children who witness domestic violence (DV) have psychosocial maladaptation that is associated with demonstrable changes in the anatomic and physiological make up of their central nervous system. Individuals with these changes do not function well in society and present communities with serious medical, sociological, and economic dilemmas. In this focused perspective, we discuss the psychosocially induced biological alterations (midbrain, cerebral cortex, limbic system, corpus callosum, cerebellum, and the hypothalamic, pituitary, and adrenal axis) that are related to maladaptation (especially post-traumatic stress disorder) in the context of child-witnessed DV, and provide evidence for these physical alterations to the brain. Herein, we hope to stimulate the necessary political discourse to encourage legal systems around the world to make the act of DV in the presence of a child, including a first time act, a stand-alone felony.
RESUMO
BACKGROUND: Enteral access device malfunction and breakage results in significant morbidity and healthcare cost. In many healthcare systems, enteral nutrition care is fragmented and inefficient. We describe the development and validation of an enteral nutrition support clinic (NSC) with a focus on prevention of enteral access complications. A care protocol consisting of pre- and postplacement visits and subsequent weekly visits was developed. Competencies were established for dietitians to staff the NSC. METHODS: A retrospective quality analysis was performed in patients before and after the implementation of an enteral NSC. Enteral access complications, emergency room visits, readmissions, unplanned physician visits, and tube replacements were recorded for 90 days after tube placement. RESULTS: Thirty patients were evaluated in the NSC pilot and compared with 22 baseline patients with adequate follow-up. The NSC resulted in an 88.9% reduction in nutrition-related emergency room visits (P = .016) and 78.1% reduction in readmissions (P = .027). Estimated per-patient cost reductions amounted to $6831. Approximately 30% of patients were seen in the NSC at least once for a clogged tube and 43.3% for tube leakage. Only 1 NSC patient required a procedure for tube reinsertion. CONCLUSION: Implementation of a dietitian-led nutrition support clinic resulted in improved quality, as well as reductions in hospital readmissions, tube-related complications, and healthcare costs

BACKGROUND: In search of a standardized noninvasive assessment of intravascular volume status, we prospectively compared the sonographic inferior vena cava collapsibility index (IVC-CI) and central venous pressures (CVPs). Our goals included the determination of CVP behavior across clinically relevant IVC-CI ranges, examination of unitary behavior of IVC-CI with changes in CVP, and estimation of the effect of positive end-expiratory pressure (PEEP) on the IVC-CI/CVP relationship. METHODS: Prospective, observational study was performed in surgical/medical intensive care unit patients between October 2009 and July 2013. Patients underwent repeated sonographic evaluations of IVC-CI. Demographics, illness severity, ventilatory support, CVP, and patient positioning were recorded. Correlations were made between CVP groupings (<7, 7-12, 12-18, 19+) and IVC-CI ranges (<25, 25-49, 50-74, 75+). Comparison of CVP (2-unit quanta) and IVC-CI (5-unit quanta) was performed, followed by assessment of per-unit ΔIVC-CI/ΔCVP behavior as well as examination of the effect of PEEP on the IVC-CI/CVP relationship. RESULTS: We analyzed 320 IVC-CI/CVP measurement pairs from 79 patients (mean [SD] age, 55.8 [16.8] years; 64.6% male; mean [SD] Acute Physiology and Chronic Health Evaluation II, 11.7 [6.21]). Continuous data for IVC-CI/CVP correlated poorly (R = 0.177, p < 0.01) and were inversely proportional, with CVP less than 7 noted in approximately 10% of the patients for IVC-CIs less than 25% and CVP less than 7 observed in approximately 85% of patients for IVC-CIs greater than or equal to 75%. Median ΔIVC-CI per unit CVP was 3.25%. Most measurements (361 of 320) were collected in mechanically ventilated patients (mean [SD] PEEP, 7.76 [4.11] cm H2O). PEEP-related CVP increase was approximately 2 mm Hg to 2.5 mm Hg for IVC-CIs greater than 60% and approximately 3 mm Hg to 3.5 mm Hg for IVC-CIs less than 30%. PEEP also resulted in lower IVC-CIs at low CVPs, which reversed with increasing CVPs. When IVC-CI was examined across increasing PEEP ranges, we noted an inverse relationship between the two variables, but this failed to reach statistical significance. CONCLUSION: IVC-CI and CVP correlate inversely, with each 1 mm Hg of CVP corresponding to 3.3% median ΔIVC-CI. Low IVC-CI (<25%) is consistent with euvolemia/hypervolemia, while IVC-CI greater than 75% suggests intravascular volume depletion. The presence of PEEP results in 2 mm Hg to 3.5 mm Hg of CVP increase across the IVC-CI spectrum and lower collapsibility at low CVPs. Although IVC-CI decreased with increasing degrees of PEEP, this failed to reach statistical significance. While this study represents a step forward in the area of intravascular volume estimation using IVC-CI, our findings must be applied with caution owing to some methodologic limitations. LEVEL OF EVIDENCE: Diagnostic study, level III. Prognostic study, level III.

Despite our decades of experience with Kaposi Sarcoma its true nature remains elusive. This angioproliferative disease of the vascular endothelium has a propensity to involve visceral organs in the immunocompromised population. There are four variants of the disease and each has its own pathogenesis and evolution. While the common sources of upper gastrointestinal bleeding are familiar to surgeons and critical care physicians, here we present the exceedingly rare report of upper gastrointestinal bleeding attributable to this malady, explore its successful management, and review the various forms of Kaposi Sarcoma including the strategies in regard to their management.

Amniotic fluid embolism (AFE) is an unpredictable and as-of-yet unpreventable complication of maternity. With its low incidence it is unlikely that any given practitioner will be confronted with a case of AFE. However, this rare occurrence carries a high probability of serious sequelae including cardiac arrest, ARDS, coagulopathy with massive hemorrhage, encephalopathy, seizures, and both maternal and infant mortality. In this review the current state of medical knowledge about AFE is outlined including its incidence, risk factors, diagnosis, pathophysiology, and clinical manifestations. Special attention is paid to the modern aggressive supportive care that resulted in an overall reduction in the still alarmingly high mortality rate of this devastating entity. The key factors for successful management and resolution of this disease process continue to be sharp vigilance, a high level of clinical suspicion, and rapid all-out resuscitative efforts on the part of all clinicians involved in the medical care of the parturient.
RESUMO
We evaluated a neural network model for prediction of glucose in critically ill trauma and post-operative cardiothoracic surgical patients. A prospective, feasibility trial evaluating a continuous glucose-monitoring device was performed. After institutional review board approval, clinical data from all consenting surgical intensive care unit patients were converted to an electronic format using novel software. This data was utilized to develop and train a neural network model for real-time prediction of serum glucose concentration implementing a prediction horizon of 75 minutes. Glycemic data from 19 patients were used to "train" the neural network model. Subsequent real-time simulated testing was performed in 5 patients to whom the neural network model was naive. Performance of the model was evaluated by calculating the mean absolute difference percent (MAD%), Clarke Error Grid Analysis, and calculation of the percent of hypoglycemic (≤70 mg/dL), normoglycemic (>70 and <150 mg/dL), and hyperglycemic (≥150 mg/dL) values accurately predicted by the model; 9,405 data points were analyzed. The models successfully predicted trends in glucose in the 5 test patients. Clark Error Grid Analysis indicated that 100.0% of predictions were clinically acceptable with 87.3% and 12.7% of predicted values falling within regions A and B of the error grid respectively. Overall model error (MAD%) was 9.0% with respect to actual continuous glucose modeling data. Our model successfully predicted 96.7% and 53.6% of the normo- and hyperglycemic values respectively. No hypoglycemic events occurred in these patients. Use of neural network models for real-time prediction of glucose in the surgical intensive care unit setting offers healthcare providers potentially useful information which could facilitate optimization of glycemic control, patient safety, and improved care. Similar models can be implemented across a wider scale of biomedical variables to offer real-time optimization, training, and adaptation that increase predictive accuracy and performance of therapies.

The relationship among traumatic injury, the associated metabolic/physiologic responses, and mortality is well established. Tissue hypoperfusion and metabolic derangement may not universally correlate with initial clinical presentation. We hypothesized that anion gap (AG) could be a useful gauge of trauma-related physiologic response and mortality in older patients with relatively lower injury acuity. We retrospectively analyzed data from 711 trauma patients older than 45 years. Parameters examined included demographics, injury characteristics, laboratories, morbidity, and mortality. Univariate and survival analyses were performed using PASW 18. A stepwise correlation exists between increasing Injury Severity Score and AG. Although AG less than 8 to 15 was not associated with a significant increase in mortality, greater mortality was seen for AG greater than 16 with further stepwise increases for AGs greater than 22. Anion gap correlated moderately with serum lactate and poorly with base excess. Increasing AG also correlated with morbidity and greater incidence of intensive care admissions. The presence of any complication increased from 28.6 per cent for patients with AG 12 or less to 45.5 per cent for patients with AG 22 or greater (P < 0.04). These findings support the contention that "low acuity" trauma patients with high AGs may not appear acutely ill but may harbor significant underlying metabolic and physiologic disturbances that could contribute to morbidity and mortality. Higher AG values (i.e., greater than 16) may be associated with worse clinical outcomes.

Wind disasters are responsible for tremendous physical destruction, injury, loss of life and economic damage. In this review, we discuss disaster preparedness and effective medical response to wind disasters. The epidemiology of disease and injury patterns observed in the early and late phases of wind disasters are reviewed. The authors highlight the importance of advance planning and adequate preparation as well as prompt and well-organized response to potential damage involving healthcare infrastructure and the associated consequences to the medical response system. Ways to minimize both the extent of infrastructure damage and its effects on the healthcare system are discussed, focusing on lessons learned from recent major wind disasters around the globe. Finally, aspects of healthcare delivery in disaster zones are reviewed.
RESUMO
BACKGROUND: Retained surgical items (RSI) continue to occur. Large RSI studies are few due to low RSI frequency in single institutions and the medicolegal implications. Consequently, RSI risks are not fully defined, with discrepancies persisting among published studies. The goals of this study were to better define risk factors for RSI, to clarify previously discrepant risk factors, and to evaluate other potential contributors to RSI occurrence, such as trainee presence during an operation. STUDY DESIGN: Multicenter case-match study of RSI risk factors was conducted between January 2003 and December 2009. Cases complicated by RSI were identified at participating centers using clinical quality improvement and adverse event reporting data. Case match controls (non-RSI) were selected from same or similar-type cases performed at each respective institution. Retained surgical item risk factors were evaluated by univariate and multivariate conditional logistic regression. RESULTS: Fifty-nine RSIs and 118 matched controls were analyzed (RSI incidence 1 in 6,975 or 59 in 411,526). Retained surgical items occurred despite use of confirmatory x-rays (13 of 27 instances) and/or radiofrequency tagging (2 of 32 instances). Among previously discrepant results, we confirmed that body mass index, unexpected intraoperative events, and procedure duration were associated with increased RSI risk. The occurrence of any safety variance, and specifically an incorrect count at any time during the procedure, was associated with elevated RSI risk. Trainee presence was associated with 70% lower RSI risk compared with trainee absence. CONCLUSIONS: Longer duration of surgery, safety variances, and incorrect counts during the procedure result in elevated RSI risk. The possible positive influence of trainee presence on RSI risk deserves additional study. Our findings highlight the need for zero tolerance for safety omissions, continued study and development of novel approaches to RSI reduction, and establishing anonymous RSI reporting systems to better track both the incidence and risks associated with this problem, which has yet to be solved.

Negative pressure pulmonary edema (NPPE) following the use of the laryngeal mask airway (LMA) is an uncommon and under-reported event. We present a case of a 58-year-old male, who developed NPPE following LMA use. After biting vigorously on his LMA, the patient developed stridor upon emergence, with concurrent appearance of blood-tinged, frothy sputum and pulmonary edema. He subsequently required three days of mechanical ventilation. After discontinuation of mechanical ventilation the patient continued to require additional pulmonary support using continuous positive airway pressure, with a full facemask, to correct the persistent hypoxemia. His roentgenographic findings demonstrated an accelerated improvement with judicious administration of intravenous furosemide.
