New legislation in New Jersey reduced opioid use among trauma patients.

PURPOSE: In New Jersey, politicians have emphasized the need to attenuate the ongoing opioid epidemic as opioid use disorder can lead to addiction and, in many cases, mortality. New legislation (New Jersey Senate Bill 3) was enacted in 2017 to reduce opioid prescription from 30 days to 5 days for acute pain in both inpatient and outpatient healthcare settings. Therefore, we sought to evaluate if the enactment of the bill influenced the consumption of opioid pain medication at an American College of Surgeons-verified Level I Trauma Center. METHODS: Patients from 2016 to 2018 were compared for differences in average daily inpatient morphine milligram equivalents (MMEs) consumption and injury severity score (ISS), among other parameters. To ensure that changes in pain medication did not affect the quality of pain management, we compared their average pain ratings. RESULTS: Although the average ISS in 2018 was higher than that in 2016 (10.6 ± 0.2 vs 9.1 ± 0.2, p < 0.001), opioid consumption decreased in 2018 without increasing the average pain rating for patients with an ISS of 9 and 10. More specifically, the average daily inpatient MMEs consumption dropped from 14.1 ± 0.5 in 2016 to 8.8 ± 0.3 in 2018 (p < 0.001). Even among patients with an average ISS >15, the total MMEs consumed per person decreased in 2018 (116.0 ± 14.0 vs 59.4 ± 7.6, p < 0.001). CONCLUSION: Overall, opioid consumption was lower in 2018 without negatively affecting the quality of pain management. This suggests that the implementation of the new legislation has successfully reduced inpatient opioid use.

The impact of gender on clinical outcomes after sustaining a pelvic fracture.

INTRODUCTION: In trauma care, pelvic fractures contribute to morbidity and mortality. Since men and women have different pelvic structures and hormonal milieu, we studied if these gender differences affect clinical outcomes after pelvic fractures. METHODS: Using the 2016 American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) database, we stratified 24,425 patients with pelvic fractures by gender. Male and female patients were analyzed for differences in comorbidities,  mechanism of injury, complications, and other clinical parameters. RESULTS: Female patients were older (p < 0.001) and had more comorbidities (p < 0.001), such as bleeding disorder, congestive heart failure, chronic obstructive pulmonary disorder, dementia, chronic renal failure, diabetes mellitus, and hypertension. Although female patients were sicker before sustaining pelvic fractures, male patients had higher rates of post-trauma complications (p < 0.001), such as acute kidney injury, deep vein thrombosis, unplanned admission to the intensive care unit (ICU), and unplanned return to the operating room (OR). Multivariate logistic regression further supports this as male gender was independently associated with a 26.1% higher risk of developing at least one complication (p < 0.001), despite having a higher average Injury Severity Score (ISS) (21.91 ± 0.09 versus 20.71 ± 0.11, p < 0.001). Interestingly, male patients also had a longer hospital length of stay than female patients (13.36 ± 0.12 days versus 11.8 2± 0.14 days, p < 0.001). CONCLUSION: Even though female patients were older and had more pre-existing comorbidities, male patients developed more complications and had longer hospital stays.

Severe dysphagia requiring gastrostomy following cervical spine fracture fixation.

BACKGROUND: The incidence of severe dysphagia requiring gastrostomy tube (GT) placement following operative fixation of traumatic cervical spine fractures is unknown. Risk factors for severe dysphagia are not well identified and GT placement is often delayed due to the belief that it will resolve quickly. We hypothesized that patient and clinical factors could be used to predict severe dysphagia requiring GT placement in this population. METHODS: A retrospective multicenter review of all adult patients requiring operative fixation of cervical spine fractures was performed. Data on demographics, injury severity score, presence of spinal cord injury, operative approach, presence of severe traumatic brain injury, and the need and timing of tracheostomy and GT were collected. The timing, number and results of formal speech, and language pathology examinations were also recorded. RESULTS: 243 patients underwent cervical spine fixation for traumatic fractures, of which 72 (30%) required GT placement. Patients requiring gastrostomy were significantly older, 54 versus 45 years (p=0.002), and had higher injury severity scores at 24 versus 18 (p<0.0001). Tracheostomy was strongly associated with severe dysphagia; GT was required in 83% of patients who underwent tracheostomy versus 5% of those who did not require tracheostomy. 50% of patients underwent tracheostomy and GT on the same day after injury, with the remaining patients having an average of 9 days delay between procedures. The need for gastrostomy placement was also higher in patients undergoing combined operative approach versus anterior or posterior approach alone (p=0.02). There were no GT-related complications. CONCLUSIONS: Severe dysphagia requiring GT placement occurs commonly (30%) in patients who undergo operative fixation of cervical spine fractures. Gastrostomy placement was delayed in 50%. Tracheostomy was strongly associated with the need for GT placement. Earlier GT placement, especially in patients requiring tracheostomy, would improve patient care and disposition.

The complex interplay between semantics and grammar in impression formation.

We sought to bridge findings showing that (a) describing a person's behavior with the perfective verb aspect (did), compared to the imperfective aspect (was doing), increases processing of semantic knowledge unrelated to the target's action such as stereotypes and (b) an increased recognition of stereotypical thoughts often promotes a judgment correction for the stereotypes. We hypothesized an interplay between grammar (verb conjugation) and semantic information (gender) in impression-formation. Participants read a resume, attributed to a male or female, for a traditionally masculine job. When the resume was written in the imperfective, people rated a male (vs. female) more positively. When the resume was in the perfective, this pattern reversed. Only these latter effects of gender were influenced by cognitive load. Further, people more quickly indicated the applicant's gender in the perfective condition, suggesting an enhanced focus on gender during processing.

Equestrian trauma: injury patterns vary among age groups.

Patients with equestrian injuries were identified in the trauma registry from 2004 to 2007. We a priori divided patients into three groups: 0 to 18 years, 19 to 49 years, and 50 years old or older. There were 284 patients identified with equestrian-related trauma. Injury Severity Score for the three major age categories 0 to 18 years, 19 to 49 years, and 50 years or older, were 3.47, 5.09, and 6.27, respectively. The most common body region injured among all patients was the head (26.1%). The most common injuries by age group were: 0 to 18 years, upper extremity fractures; 19 to 49 year olds, concussions; and 50 years or older, rib fractures. Significant differences were observed among the three age groups in terms of percent of patients with rib fractures: percent of patients with rib fractures was 2, 8, and 22 per cent in age groups 0 to 18, 19 to 49, and 50 years or older, respectively. We found different patterns of injuries associated with equestrian accidents by age. Head injuries were commonly seen among participants in equestrian activities and helmet use should be promoted to minimize the severity of closed head injuries. Injury patterns also seem to vary among the various age groups that ride horses. This information could be used to better target injury prevention efforts among these patients.

Standard computed tomography of the chest, abdomen, and pelvis is sensitive and cost-effective for the detection of fractures of the shoulder girdle.

Computed tomography of the chest, abdomen, and pelvis (CTCAP) has become the mainstay of diagnosis in stable blunt trauma patients. The purpose of this study was to investigate whether standard CTCAP has adequate sensitivity to identify fractures of the scapula, clavicle, and humeral head to replace routine radiographs of the shoulder. A retrospective chart review was carried out from January 1, 2004, to December 31, 2007, at Morristown Memorial Hospital. Inclusion criteria were all shoulder fracture patients in our trauma registry who underwent both a CTCAP and plain radiographs of the injured shoulder. Data were collected for patient age, sex, Injury Severity Score, mechanism of injury, and fracture location. Sensitivity was calculated for each diagnostic modality as well as hospital costs and radiation dose of plain radiographs. A total of 374 charts were reviewed and 98 patients were included in the study with a total of 117 fractures. The sensitivity of trauma CTCAP for scapula fractures was 100 per cent, clavicle fractures 98 per cent, and humeral head fractures 100 per cent. The sensitivity of the shoulder series for scapula fractures was 60 per cent, clavicle fractures 85 per cent, and humeral head fractures 100 per cent. The plain radiographs added $298 in hospital charges and 0.191 mSv of radiation per patient. CTCAP is a sensitive tool for identifying fractures in the shoulder girdle. Therefore, CTCAP can replace the routine radiographs of the shoulder resulting in less total radiation exposure of the trauma patients. This also would lead to lower healthcare cost and better diagnostic workflow.

Does patient age and height of fall alone require trauma team activation?

Our American College of Surgeons Level I trauma center uses physiological data and injury patterns to identify fall patients at risk. We hypothesized that height of fall and patient age impacted injury severity and analyzed if they were significant predictors of the need for trauma team activation. Charts were reviewed from July 1, 2004, to June 30, 2007, for age; sex; Injury Severity Score (ISS); height of fall and admission to the intensive care unit, operating room, stepdown unit, floor; or death. Exclusion criteria were physiological, neurologic, or airway compromise and penetrating neck or torso injuries. ISS was used as a positive control. A total of 1865 fall patients were treated during the period of data collection, and 1348 patients were eliminated by exclusion criteria, leaving 517 patients for study. Although patient age did not correlate with the need for trauma team activation, there was a statistically significant association between age and admission to the hospital from the emergency room (P < 0.05; area under curve [AUC] = 0.713; 95% confidence interval [CI], 0.656 to 0.770). Similarly, although the height of fall alone did not have a significant predictive value for the need of trauma team activation, there was a clear association of the height of fall with hospital admission (AUC = 0.589; 95% CI, 0.519 to 0.658). Patient age and height of fall alone are not criteria for trauma team activation in the absence of physiological, neurologic, or airway compromise.

Effectiveness of prehospital wireless transmission of electrocardiograms to a cardiologist via hand-held device for patients with acute myocardial infarction (from the Timely Intervention in Myocardial Emergency, NorthEast Experience [TIME-NE]).

Percutaneous coronary intervention for patients with ST-segment elevation myocardial infarction (STEMI) decreases morbidity and mortality if performed within the first 2 hours of symptom onset. However, the American College of Cardiology/American Heart Association guideline for percutaneous coronary intervention door-to-balloon time (<90 minutes) in patients with STEMI is a infrequently accomplished goal. This study enrolled 277 patients with STEMI who were self-transported or transported by emergency medical services to NorthEast Medical Center for primary percutaneous coronary intervention. This study tested the hypothesis that prehospital wireless transmission of an electrocardiogram to a cardiologist's hand-held device results in shorter emergency department door-to-reperfusion time. A comparison was made between patients whose electrocardiogram was successfully transmitted during the intervention phase with (1) patients transported by the emergency medical services in the preintervention, (2) patients self-transported in the intervention phase, and (3) patients whose wireless transmission failed in the intervention phase. During the preintervention phase (2001 to 2003), 48 patients were enrolled. During the intervention phase (2003 to 2005), the following patients were enrolled: 101 self-transported patients, 24 patients with successful electrocardiographic transmission, and 19 patients for whom transmission failed. The median door-to-reperfusion time for patients with successful electrocardiographic transmission was 50 minutes, which was significantly shorter than a preintervention time of 101 minutes (p <0.0001), an intervention phase self-transport time of 96 minutes (p <0.0001), and a failed transmission time of 78 minutes (p <0.0001). In conclusion, prehospital wireless electrocardiographic transmission to a cardiologist's hand-held device significantly decreased emergency department door-to-reperfusion time, thus achieving the American College of Cardiology/American Heart Association guideline for patients with STEMI.

Lymph from a primate baboon trauma hemorrhagic shock model activates human neutrophils.

We have reported that toxic factors in intestinal lymph are responsible for acute lung injury and bone marrow suppression and that they contribute to a systemic inflammatory state based on studies in rodent models of trauma-hemorrhagic shock. Rodent models may not completely reflect the responses of injured patients. Thus, it is important to confirm these findings in primates before applying them to injured human patients with trauma. Thus, we have recently established baboon trauma-hemorrhagic shock (T/HS) and trauma-sham shock (T/SS) models that showed that gut-derived factors carried in the lymph potentiates lung injury and causes human endothelial dysfunction and suppresses human bone marrow progenitor cell growth. Here, we further investigated the effects of these primate lymph samples on human neutrophils. We hypothesized that toxic factors in baboon lymph may prime and/or activate human polymorphonuclear leukocyte (PMN) leading to overproduction of superoxide, thereby contributing to the development of adult respiratory distress syndrome and multiple organ failure. To this effect, we have examined the priming effect of baboon T/HS and T/SS lymph on PMN respiratory burst and expression of adhesion molecule in human neutrophils. The results of these studies indicate that PMN treated with baboon T/HS lymph showed significantly induced respiratory burst responses compared with PMN treated with T/SS lymph or medium when phorbol myristate acetate PMA was applied after lymph pretreatment. Secondly, we found that the expression of CD11b adhesion molecule was increased by incubation with T/HS lymph. These results suggest that baboon lymph from T/HS models can increase respiratory burst and adhesion molecule expression in human PMN, thereby potentially contributing to PMN-mediated organ injury.

Spinal clearance in the difficult trauma patient: a role for screening MRI of the spine.

Identifying spinal injuries in trauma patients with altered mental status can be difficult. CT scanning and clinical examination are the basis of our spinal clearance, but screening "trauma protocol" spinal MRI is used to exclude occult injuries. We sought to evaluate the sensitivity of CT scanning for spinal injuries compared with our MRI protocol. Ninety-seven patients underwent MRI cervical spine trauma protocol during 2004. Twenty-nine patients were obtunded, 29 had neurologic symptoms, and 39 had spine pain. MRI confirmed the initial CT findings without new injuries in 83 cases. MRI reclassified fractures as degenerative changes in 12 cases. In 2 cases, the MRI identified new injuries: one a stable partial ligament tear, the second a T7 Chance fracture with ligamental disruption requiring operative fixation. There was no morbidity or mortality documented in obtaining the MRI studies. Overall negative predictive value of CT scanning of the spine was 98 per cent, the positive predictive value was 78 per cent, and the sensitivity and specificity was 94 per cent and 91 per cent, respectively. CT scanning of the cervical and axial spine is sensitive for spinal trauma but not specific. MRI trauma protocol should be reserved for cases when initial CT scanning is suggestive of traumatic injury.

Ceramide content is increased in skeletal muscle from obese insulin-resistant humans.

Increased intramyocellular lipid concentrations are thought to play a role in insulin resistance, but the precise nature of the lipid species that produce insulin resistance in human muscle are unknown. Ceramides, either generated via activation of sphingomyelinase or produced by de novo synthesis, induce insulin resistance in cultured cells by inhibitory effects on insulin signaling. The present study was undertaken to determine whether ceramides or other sphingolipids are increased in muscle from obese insulin-resistant subjects and to assess whether ceramide plays a role in the insulin resistance of Akt in human muscle. Lean insulin-sensitive and obese insulin-resistant subjects (n = 10 each) received euglycemic-hyperinsulinemic clamps with muscle biopsies basally and after 30, 45, or 60 min of insulin infusion. The rate of glucose infusion required to maintain euglycemia (reflecting glucose uptake) was reduced by >50%, as expected, in the obese subjects at each time point (P < 0.01). Under basal conditions, total muscle ceramide content was increased nearly twofold in the obese subjects (46 +/- 9 vs. 25 +/- 2 pmol/2 mg muscle, P < 0.05). All species of ceramides were increased similarly in the obese subjects; in contrast, no other sphingolipid was increased. Stimulation of Akt phosphorylation by insulin in the obese subjects was significantly reduced after 30 min (0.96 +/- 0.11 vs. 1.84 +/- 0.38 arbitrary units) or 45-60 min (0.68 +/- 0.17 vs. 1.52 +/- 0.26) of insulin infusion (P < 0.05 for both). Muscle ceramide content was significantly correlated with the plasma free fatty acid concentration (r = 0.51, P < 0.05). We conclude that obesity is associated with increased intramyocellular ceramide content. This twofold increase in ceramide may be involved in the decrease in Akt phosphorylation observed after insulin infusion and could theoretically play a role in the reduced ability of insulin to stimulate glucose uptake in skeletal muscle from obese subjects.

Inflammatory chemoreceptor cross-talk suppresses leukotriene B4 receptor 1-mediated neutrophil calcium mobilization and chemotaxis after trauma.

G protein-coupled chemoattractants recruit neutrophils (PMN) to sites of injury and infection. The leukotrienes (LT) and CXC chemokines (CXC) and their receptors (BLT1/BLT2 and CXCR1/CXCR2) are all known to play roles in these responses. Each system has been studied separately in vitro, but in vivo they act concurrently, and the clinical interactions between the two systems are unstudied. We prospectively studied calcium mobilization and chemotactic responses to LTB(4) in PMN from major trauma patients. The responses of the high affinity BLT1 receptor were suppressed at the 3-day postinjury time point, but recovered by 1 wk. Trauma patients had transient elevations of plasma LT and CXC levels. Functional deficits identical with those in trauma PMN were reproduced in vitro by exposing healthy PMN to CXCs at the elevated plasma concentrations found. Functional responses to LTB(4) were suppressed by cross-talk with CXC and BLT2 receptors that desensitize BLT1. Since the suppression of intracellular calcium mobilization was prominent, we also studied the role of suppressed cell calcium mobilization in the defective chemotactic responses to LTB(4). We noted that PMN chemotaxis to LTB(4) showed far more dependence on store-operated calcium entry than on the release of cellular calcium stores, and that store-operated calcium responses to BLT1 activation were markedly inhibited during the same time period as was chemotaxis. The intermittent release of inflammatory mediators after injury can blunt PMN responses to LTs by suppressing BLT1 as well as downstream calcium entry. Diminished LT receptor activity due to cross-talk with CXC receptors can inhibit PMN recruitment to infective sites. This may predispose injured patients to septic complications.
