Mental Illness as a Predictor of Subjective Happiness Among University Employees Working in Hawai'i.

The World Health Organization adopted happiness as an indicator of societal progress in addressing conditions that directly affect psychological well-being and recommended communities address the determinants and obstacles to subjective well-being. Therefore, we conducted an online survey, informed by the Sustainable Happiness Model, among university employees that measured life circumstances (sociodemographics) and intentional leisure-time moderate-to-vigorous physical activity as potential predictors of subjective happiness (assessed using the Subjective Happiness Scale [SHS]). The multiethnic sample (N = 85) primarily included those who identified as White (44%), Asian (33%), and Native Hawaiian and other Pacific Islander (16%). The most prevalent age range was 41 to 50 years (31%), and 55% of the sample identified as female, 78% as faculty, and 22% as staff. Reporting a current mental health condition had significantly lower SHS scores compared to all other factors. Future research should explore interventions to support and improve university employee's mental health and overall well-being.

Endovascular treatment of axillosubclavian arterial injuries is a safe alternative to open repair.

BACKGROUND: Injuries to the axillosubclavian arteries are rare, comprising 5% of all extremity trauma. This study aims to examine contemporary outcomes of traumatic axillosubclavian injuries. METHODS: A retrospective review was performed on patients admitted with innominate, subclavian, and/or axillary artery injuries to a level 1 trauma center from 2011 to 2021. Patients undergoing endovascular repair were compared to those with open repair. RESULTS: Thirty two patients met inclusion criteria. Injuries were approached open in 22 (59%) cases and endovascular in 10 (27%). There was no difference in 30-day mortality or hospital length of stay between endovascular and open repair. Endovascular repairs had shorter operative times (1.9 vs 3.1 h, p = 0.009) and lower blood loss (72 vs 1662 mL, p < 0.001). CONCLUSIONS: Endovascular repair of axillosubclavian arterial injuries demonstrate similar outcomes to open repair. Significantly shorter operative times and lower blood loss suggest potential decreased morbidity.

Does autotransfusion from a contaminated trauma laparotomy field increase the risk of complications?

BACKGROUND: Autotransfusion (AT) in trauma laparotomy is limited by concern that enteric contamination (EC) increases complications, including infections. Our goal was to determine if AT use increases complications in trauma patients undergoing laparotomy with EC. METHODS: Trauma patients undergoing laparotomy from October 2011-November 2020 were reviewed. Patients were excluded if they did not receive blood in the operating room, did not have a full thickness hollow viscus injury, or died <24 h from admission. AT and non-AT patients were matched. Outcomes were compared. RESULTS: 185 patients were included, 60 received AT, and 46 pairs were matched. After matching, demographics were similar. No differences were noted in septic complications (33 vs 41%, p = 0.39), overall complications (59% vs 54%, p = 0.67), or mortality (13 vs 6%, p = 0.29). CONCLUSIONS: AT use in contaminated trauma laparotomy fields was not associated with a higher rate of complications.

Mortality in hypotensive trauma patients requiring laparotomy is related to degree of hypotension and provides evidence for focused interventions.

BACKGROUND: Mortality in hypotensive patients requiring laparotomy is reported to be 46% and essentially unchanged in 20 years. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been incorporated into resuscitation protocols in an attempt to decrease mortality, but REBOA can have significant complications and its use in this patient group has not been validated. This study sought to determine the mortality rate for hypotensive patients requiring laparotomy and to evaluate the mortality risk related to the degree of hypotension. Additionally, this study sought to determine if there was a presenting systolic blood pressure (SBP) that was associated with a sharp increase in mortality to target the appropriate patient group most likely to benefit from focused interventions such as REBOA. METHODS: The trauma registry at a level I trauma center was reviewed for patients undergoing emergent laparotomy from January 2007 to June 2020. Data included demographics, mechanism of injury, physiological data, Injury Severity Score, blood products transfused, and outcomes. Group comparisons were based on initial SBP (0 to 50 mm Hg, 60 to 69 mm Hg, 70 to 79 mm Hg, 80 to 89 mm Hg, and ≥90 mm Hg). RESULTS: During the study period, 52 016 trauma patients were treated and 1174 required laparotomy within 90 min of arrival; 424 had an initial SBP of <90 mm Hg. The overall mortality rate was 18%, but mortality increased as SBP decreased (≥90=9%, 80 to 89=20%, 70 to 79=21%, 60 to 69=48%, 0 to 59=66%). Mortality increased sharply with SBP of <70 mm Hg. DISCUSSION: Mortality rate increases with worsening hypotension and increases sharply with an SBP of <70 mm Hg. Further study on focused interventions such as REBOA should target this patient group. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Descriptive exploration of overdose codes in hospital and emergency department discharge data to inform development of drug overdose morbidity surveillance indicator definitions in ICD-10-CM.

BACKGROUND: In October 2015, discharge data coding in the USA shifted to the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM), necessitating new indicator definitions for drug overdose morbidity. Amid the drug overdose crisis, characterising discharge records that have ICD-10-CM drug overdose codes can inform the development of standardised drug overdose morbidity indicator definitions for epidemiological surveillance. METHODS: Eight states submitted aggregated data involving hospital and emergency department (ED) discharge records with ICD-10-CM codes starting with T36-T50, for visits occurring from October 2015 to December 2016. Frequencies were calculated for (1) the position within the diagnosis billing fields where the drug overdose code occurred; (2) primary diagnosis code grouped by ICD-10-CM chapter; (3) encounter types; and (4) intents, underdosing and adverse effects. RESULTS: Among all records with a drug overdose code, the primary diagnosis field captured 70.6% of hospitalisations (median=69.5%, range=66.2%-76.8%) and 79.9% of ED visits (median=80.7%; range=69.8%-88.0%) on average across participating states. The most frequent primary diagnosis chapters included injury and mental disorder chapters. Among visits with codes for drug overdose initial encounters, subsequent encounters and sequelae, on average 94.6% of hospitalisation records (median=98.3%; range=68.8%-98.8%) and 95.5% of ED records (median=99.5%; range=79.2%-99.8%), represented initial encounters. Among records with drug overdose of any intent, adverse effect and underdosing codes, adverse effects comprised an average of 74.9% of hospitalisation records (median=76.3%; range=57.6%-81.1%) and 50.8% of ED records (median=48.9%; range=42.3%-66.8%), while unintentional intent comprised an average of 11.1% of hospitalisation records (median=11.0%; range=8.3%-14.5%) and 28.2% of ED records (median=25.6%; range=20.8%-40.7%). CONCLUSION: Results highlight considerations for adapting and standardising drug overdose indicator definitions in ICD-10-CM.

Interrupted time series analysis to evaluate the performance of drug overdose morbidity indicators shows discontinuities across the ICD-9-CM to ICD-10-CM transition.

INTRODUCTION: On 1 October 2015, the USA transitioned from the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) to the International Classification of Diseases, 10th Revision (ICD-10-CM). Considering the major changes to drug overdose coding, we examined how using different approaches to define all-drug overdose and opioid overdose morbidity indicators in ICD-9-CM impacts longitudinal analyses that span the transition, using emergency department (ED) and hospitalisation data from six states' hospital discharge data systems. METHODS: We calculated monthly all-drug and opioid overdose ED visit rates and hospitalisation rates (per 100 000 population) by state, starting in January 2010. We applied three ICD-9-CM indicator definitions that included identical all-drug or opioid-related codes but restricted the number of fields searched to varying degrees. Under ICD-10-CM, all fields were searched for relevant codes. Adjusting for seasonality and autocorrelation, we used interrupted time series models with level and slope change parameters in October 2015 to compare trend continuity when employing different ICD-9-CM definitions. RESULTS: Most states observed consistent or increased capture of all-drug and opioid overdose cases in ICD-10-CM coded hospital discharge data compared with ICD-9-CM. More inclusive ICD-9-CM indicator definitions reduced the magnitude of significant level changes, but the effect of the transition was not eliminated. DISCUSSION: The coding change appears to have introduced systematic differences in measurement of drug overdoses before and after 1 October 2015. When using hospital discharge data for drug overdose surveillance, researchers and decision makers should be aware that trends spanning the transition may not reflect actual changes in drug overdose rates.

Admission base deficit is superior to lactate in identifying shock and resuscitative needs in trauma patients.

BACKGROUND: Base Deficit (BD) and lactate have been used as indicators of shock and resuscitation. This study was done to evaluate the utility of BD and lactate in identifying shock and resuscitative needs in trauma patients. METHODS: A prospective observational study was performed from 3/2014-12/2018. Data included demographics, admission systolic BP, ISS, BD, lactate, blood transfusion, and outcomes. BD and lactate were modeled continuously and categorically and compared. RESULTS: 2271 patients were included. BD and lactate were moderately correlated (r2 = 0.63 p < 0.001). On univariate regression, BD and lactate were associated with transfusion requirement and mortality (p < 0.001), but on multivariate regression, only BD was associated with transfusion requirement and mortality (OR = 1.2, p < 0.001; OR = 1.1, p < 0.001, respectively). BD discriminated better than lactate for hypotension, higher ISS, increased transfusion requirements and mortality. CONCLUSIONS: Admission BD and lactate levels are correlated following injury, but BD is superior to lactate in identifying shock, resuscitative needs and mortality in severely injured trauma patients.

Incidence of hyponatremia in patients given levetiracetam vs. phenytoin for early posttraumatic seizure prophylaxis.

BACKGROUND: Levetiracetam and phenytoin are comparable for acute posttraumatic seizure(PTS) prophylaxis. Levetiracetam-induced hyponatremia has been reported in non-trauma patients. We studied hyponatremia in posttraumatic intracranial hemorrhage(ICH) patients receiving either drug. METHODS: Retrospective review of patients with ICH receiving PTS prophylaxis was performed. Patients were categorized by degree of sodium nadir: normal, mild, moderate, or severe, and analyzed by levetiracetam versus phenytoin. Patients were matched 2:1 regarding age and injury severity score(ISS). Incidence and treatment for hyponatremia was examined. RESULTS: 1735 ICH patients received PTS prophylaxis over an 8-year period. After exclusions and matching, there were 282 phenytoin and 564 levetiracetam patients. Age, ISS and initial sodium were comparable between the matched cohorts. There was no clinically significant difference in the rate or degree of hyponatremia. Treatment was more common in levetiracetam patients. DISCUSSION: There was a small but clinically insignificant difference in the incidence of hyponatremia in traumatic ICH patients receiving levetiracetam vs. phenytoin for PTS prophylaxis. There was an increased rate of intervention for hyponatremia in the levetiracetam group, possibly due to a coincidental preventive paradigm shift.

Gastrobronchial Fistula after Robotic Repair of Traumatic Diaphragmatic Hernia.

Gastrobronchial fistulas are a rare occurrence in the literature. We report a case of a gastrobronchial fistula after robotic repair of a chronic traumatic diaphragmatic hernia. The patient had severe respiratory symptoms with multiple studies that were inconclusive. The fistula was ultimately discovered after an esophagogastroduodenoscopy (EGD). The patient underwent a left thoracotomy for takedown of his fistula and eventually recovered. Earlier EGD and a lower threshold for differential that included this diagnosis would have led to an earlier identification and treatment of a rare disease process.

Intercostal Nerve Block with Liposomal Bupivacaine vs Epidural Analgesia for the Treatment of Traumatic Rib Fracture.

BACKGROUND: Rib fractures are common among trauma patients and analgesia remains the cornerstone of treatment. Intercostal nerve blocks provide analgesia but are limited by the duration of the anesthetic. This study compares outcomes of epidural analgesia with intercostal nerve block using liposomal bupivacaine for the treatment of traumatic rib fractures. METHODS: A retrospective chart review was used to identify patients who received either epidural analgesia or intercostal nerve block with liposomal bupivacaine for the treatment of traumatic rib fractures. Patients were matched in a 1:1 ratio on age, Injury Severity Score, and number of rib fractures. Outcomes included intubations, mechanical ventilation days, ICU length of stay (LOS), hospital LOS, and mortality. RESULTS: After matching, 116 patients were included in the study. Patients receiving intercostal nerve blocks with liposomal bupivacaine were less likely to require intubation (3% vs 17%; p = 0.015), had shorter hospital LOS (mean ± SD 8 ± 6 days vs 11 ± 9 days; p = 0.020) and ICU LOS (mean ± SD 2 ± 5 days vs 5 ± 6 days; p = 0.007). There were no differences in ventilator days or mortality. Minor complications occurred in 26% of patients that received an epidural catheter for rib fractures. No complications occurred in the patients receiving intercostal nerve block. CONCLUSIONS: Patients who received intercostal nerve blocks with liposomal bupivacaine required intubation less frequently and had shorter ICU and hospital LOS compared with epidural analgesia patients. These results suggest that intercostal nerve blocks with liposomal bupivacaine might be equal or superior to epidural analgesia.

Prospective evaluation of admission cortisol in trauma.

BACKGROUND: A low cortisol level has been shown to occur soon after trauma, and is associated with increased mortality. The purpose of this study was to investigate the impact of low cortisol levels in acute critically ill trauma patients. We hypothesized that patients would require increase vasopressor use, have a greater blood product administration, and increased mortality rate. METHODS: A blinded, prospective observational study was performed at an American College of Surgeons verified Level I trauma center. Adult patients who met trauma activation criteria, received initial treatment at Community Regional Medical Center and were admitted to the intensive care unit were included. Total serum cortisol levels were measured from the initial blood draw in the emergency department. Patients were categorized according to cortisol ≤15 µg/dL (severe low cortisol, SLC), 15.01-25 µg/dL (relative low cortisol, RLC), or >25 µg/dL (normal cortisol, NC) and compared on demographics, injury severity score, initial vital signs, blood product usage, vasopressor requirements, and mortality. RESULTS: Cortisol levels were ordered for 280 patients; 91 were excluded and 189 were included. Penetrating trauma accounted for 19% of injuries and blunt trauma for 81%. 22 patients (12%) had SLC, 83 (44%) had RLC, and 84 (44%) had NC. This study found patients with admission SLC had higher rates of vasopressor requirements, required more units of blood, and had a higher mortality rate than both the RLC and NC groups. CONCLUSION: Low cortisol level can be identified acutely after severe trauma. Trauma patients with SLC had larger blood product requirements, vasopressor use, and increase mortality. Initial cortisol levels are useful in identifying these high-risk patients. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

Changes in splenic capsule with aging; beliefs and reality.

BACKGROUND: Research describing the splenic capsule and its effect on non-operative management of splenic injuries is limited. The aim of this study is to identify the current beliefs about the splenic capsule thickness and investigate changes in the splenic capsule with age. METHODS: Trauma Medical Directors were surveyed on their beliefs regarding splenic capsule thickness changes with age. Thicknesses of cadaveric splenic capsule samples were measured. RESULTS: The majority of trauma medical directors (59%) believe the capsule thickness decreases with age. There were 94 splenic specimens obtained. The splenic capsules of infants were thin and had a uniform layer of elastin fibers. With aging, the capsule becomes thick and develops a collagen layer. CONCLUSION: Most trauma directors believe the splenic capsule thickness decreases with age. However, our results demonstrate that the splenic capsule thickness increases during childhood but remains constant in adulthood.

The impact of obesity on severity of solid organ injury in the adult population at a Level I trauma center.

BACKGROUND: The obese (body mass index, BMI > 30) have been identified as a subgroup of patients in regards to traumatic injuries. A recent study found that high-grade hepatic injuries were more common in obese than non-obese pediatric patients. This study seeks to evaluate whether similar differences exist in the adult population and examine differences in operative versus non-operative management between the obese and non-obese in blunt abdominal trauma. METHODS: Patient with trauma evaluated at an American College of Surgeons verified Level I trauma center from February 2013 to November 2016 were retrospectively reviewed. All patients aged >18 years with blunt mechanism of injury and a BMI listed in the trauma registry were included. Patients were excluded for incomplete data, including BMI or inability to grade hepatic or splenic injury. Data collected included age, gender, BMI, injury severity score, hospital length of stay, procedures on liver or spleen, and mortality. Organ injuries were scored using the American Association for the Surgery of Trauma grading scales, and were determined by either imaging or intraoperative findings. Obesity was classified as BMI > 30 compared with non-obese with BMI < 30. RESULTS: During the study period, 9481 patients were included. There were 322 spleen injuries and 237 liver injuries, with 64 patients sustaining both liver and splenic injuries. No differences existed in the percentage of high-grade hepatic or splenic injuries between the obese and non-obese. Obese patients with liver injuries were more likely to have procedural intervention than non-obese liver injuries and had higher rates of mortality. No differences were found in intervention for splenic injury between obese and non-obese. CONCLUSIONS: Contrary to prior studies on adult and pediatric patients with trauma, this study found no difference between obese and non-obese patients in severity of solid organ injury after blunt abdominal trauma in the adult population. However, there was an increased rate of procedural intervention and mortality for obese patients with liver injuries. LEVEL OF EVIDENCE: 3.

A predictive grading scale for acute cholecystitis.

BACKGROUND: Acute cholecystitis presents in a spectrum of severity, where acute disease may be complicated by severe inflammation, gangrene, and perforation. The goal of this study is to outline an evidence-based grading scale that predicts patient outcomes after laparoscopic cholecystectomy (LC). METHODS: A retrospective review of all patients with a preoperative diagnosis of acute cholecystitis who underwent LC from August 2011 until June 2015 at a tertiary-level hospital was performed. Patients who underwent elective cholecystectomy, incidental cholecystectomy, a planned open cholecystectomy, had gallstone pancreatitis or choledocholithiasis, and those admitted to a non-surgical service were excluded. Severity of disease was obtained from operative and pathology reports, and patients were classified according to the following grading scale:Grade I: symptomatic cholelithiasis.Grade II: acute/chronic cholecystitis.Grade III: gangrenous/necrotizing cholecystitis.Grade IV: gallbladder perforation or abscess.The groups were compared on age, gender, body mass index, severity of gallbladder disease, presence of preoperative systemic inflammatory response syndrome, hospital length of stay, length of operation, complications within 30 days, conversion to open rate, and cost of hospitalization. RESULTS: During the study period, 1252 patients who underwent laparoscopic cholecystectomy were analyzed; 677 met inclusion criteria. The most common grade was grade 2, which was present in 80% of patients, followed by grade 3, which was found in 16% of patients. Grade 4 cholecystitis occurred in 1.2% of patients and grade 1 occurred in 3.2% of patients. There were statistically significant increases in age, presence of preoperative systemic inflammatory response syndrome, hospital length of stay, conversion to open rate, cost of hospitalization, and length of operation with increased cholecystitis grade. CONCLUSIONS: The proposed grading scale is an accurate predictor of duration of operation, conversion to open rate, hospital length of stay, and cost of hospitalization. LEVEL OF EVIDENCE: III. STUDY TYPE: Prognostic.

After the embo: predicting non-hemorrhagic indications for splenectomy after angioembolization in patients with blunt trauma.

BACKGROUND: Successful non-operative management (NOM) of blunt splenic trauma is enhanced with splenic angioembolization (SAE). Patients may still require splenectomy post-SAE for splenic infarction/necrosis. Prior studies have used white blood cell count (WBC), platelet count (PLT), and PLT:WBC ratio after splenectomy to predict complications, but none have evaluated these findings prior to splenectomy in patients who have undergone SAE. Changes in these values may indicate clinically significant splenic infarction, facilitating management of these patients. METHODS: Patients admitted to an American College of Surgeons verified level 1 trauma center from January 2007 to August 2017 who underwent SAE were identified. Patients with successful NOM after SAE (SAE/NOM) were compared with those requiring splenectomy (SAE/SPLEN). Data included demographics, splenic injury grade, Injury Severity Score (ISS), time to SAE and splenectomy, intensive care unit and hospital length of stay (LOS), and complete blood count. Lab values were analyzed immediately post-SAE (time 1) and day 5 post-SAE (or day of discharge) for SAE/NOM patients and day of SPLEN for SAE/SPLEN patients (time 2). Data were analyzed using Mann-Whitney U, χ2 tests, and receiver operating characteristic (ROC) curves with significance attributed to P<0.05. RESULTS: Of 124 patients undergoing SAE, 16 (13%) later required SPLEN for infarction/necrosis at a median of 5 days post-SAE (IQR: 3-10 days). SAE/SPLEN and SAE/NOM patients did not differ by age, gender, ISS, or grade of splenic injury. SAE/SPLEN patients had longer hospital LOS (23 vs. 10 days, P<0.001). WBC, PLT, and PLT:WBC ratio did not differ between the groups at time 1. At time 2, WBC was higher and PLT:WBC ratio was lower in SAE/SPLEN patients. Using ROC curves at time 2, the area under the curve was 0.90 (P<0.001) for WBC and 0.71 (P<0.007) for PLT:WBC ratio. DISCUSSION: Patients requiring splenectomy for clinically significant infarction/necrosis after SAE develop leukocytosis and decreased PLT:WBC ratio when compared with SAE/NOM patients. Monitoring these parameters allows more prompt diagnosis and operative intervention. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

A method for the long-term cultivation of mammalian cells in the absence of oxygen: Characterization of cell replication, hypoxia-inducible factor expression and reactive oxygen species production.

The center of tumors, stem cell niches and mucosal surfaces all represent areas of the body that are reported to be anoxic. However, long-term study of anoxic cell physiology is hindered by the lack of a sustainable method permitting cell cultivation in the complete absence of oxygen. A novel methodology was developed that enabled anoxic cell cultivation (17d maximum time tested) and cell passage. In the absence of oxygen, cell morphology is significantly altered. All cells tested exhibited morphologic changes, i.e., a combination of tethered (monolayer-like) and runagate (suspension-like) morphologies. Both morphologies replicated (Vero and HeLa cells tested) and could be passaged anaerobically. In the absence of exogenous oxygen, anoxic cells produced reactive oxygen species (ROS). Anaerobic runagate HeLa and Vero cells increased ROS production from day 3 to day 10 by 2- and 3-fold, respectively. In contrast, anoxic tethered HeLa and Vero cells either showed no significant change in ROS production between days 3 and 10 or exhibited a 3-fold decrease in ROS, respectively. Detection of ROS was inversely related to detection of hypoxia-inducible factor-1α (HIF1) mRNA and HIF-1 protein expression which cycled over a 10-day period. This methodology has broad applications for the study of tumor and stem cell physiology as well as gastrointestinal cell-microbiome interactions. In addition, sustainable anaerobic cell culture may lead to the identification of novel pathways and targets for chemotherapeutic drug development.

Base deficit is superior to lactate in trauma.

BACKGROUND: Base Deficit (BD) and lactate have been used as indicators of shock and resuscitation. This study was done to determine the association of BD and lactate and to determine if one is superior. METHODS: A retrospective review from 3/2014-12/2016 was performed. Data included demographics, systolic BP, ISS, BD, lactate, blood transfusion, and outcomes. BD and lactate were modeled continuously and categorically and compared. RESULTS: 1191 patients were included. BD and lactate correlated strongly (r = -0.76 p < 0.001). Higher lactate and more negative BD were associated with transfusion and mortality. On multivariate regression, only BD was associated with transfusion (OR = 0.8, p < 0.001). As a categorical variable, worsening BD was associated with decreased BP, higher ISS, increased transfusions and worse outcomes. CONCLUSIONS: BD and lactate are strongly related. BD was superior to lactate in assessing the need for transfusion. The BD categories discriminate high risk trauma patients better than lactate.

Attempting to validate the overtriage/undertriage matrix at a Level I trauma center.

BACKGROUND: The Optimal Resources Document mandates trauma activation based on injury mechanism, physiologic and anatomic criteria and recommends using the overtriage/undertriage matrix (Matrix) to evaluate the appropriateness of trauma team activation. The purpose of this study was to assess the effectiveness of the Matrix method by comparing patients appropriately triaged with those undertriaged. We hypothesized that these two groups are different, and Matrix does not discriminate the needs or outcomes of these different groups of patients. METHODS: Trauma registry data, from January 2013 to December 2015, at a Level I trauma center, were reviewed. Overtriage and undertriage rates were calculated by Matrix. Patients with Injury Severity Score (ISS) of 16 or greater were classified by activation level (full, limited, consultation), and triage category by Matrix. Patients in the limited activation and consultation groups were compared with patients with full activation by demographics, injuries, initial vital signs, procedures, delays to procedure, intensive care unit admission, length of stay, and mortality. RESULTS: Seven thousand thirty-one patients met activation criteria. Compliance with American College of Surgeons tiered activation criteria was 99%. The Matrix overtriage rate was 45% and undertriage was 24%. Of 2,282 patients with an ISS of 16 or greater, 1,026 were appropriately triaged (full activation), and 1,256 were undertriaged. Undertriaged patients had better Glasgow Coma Scale score, blood pressure, and base deficit than patients with full activation. Intensive care unit admission, hospital stays, and mortality were lower in the undertriaged group. The undertriaged group required fewer operative interventions with fewer delays to procedure. CONCLUSION: Despite having an ISS of 16 or greater, patients with limited activations were dissimilar to patients with full activation. Level of activation and triage are not equivalent. The American College of Surgeons Committee on Trauma full and tiered activation criteria are a robust means to have the appropriate personnel present based on the available prehospital information. Evaluation of the process of care, regardless of level of activation, should be used to evaluate trauma center performance. LEVEL OF EVIDENCE: Therapeutic and care management, level III.

Examining Factors Associated With Nonadherence And Identifying Providers Caring For Nonadherent Subgroups.

OBJECTIVES: To examine racial/ethnic and regional differences in medication adherence in patients with diabetes taking oral anti-diabetic, anti-hypertensive, and cholesterol lowering medications and to identify the pharmacies and prescribers who serve these communities. METHODS: Administrative claims data was analyzed for members enrolled in a large health plan in Hawaii (2008-2010) with diabetes mellitus who were taking three types of medications: 1) oral anti-diabetic medications; 2) anti-hypertensive medications; 3) cholesterol lowering medications (n=5136). The primary outcome was medication adherence based on medication possession ratios. Multivariable logistic regression models were estimated to examine the association between race/ethnicity and region to adherence to each drug class separately, followed by non-adherence to all three. Covariates included age, gender, education level, chronic conditions, copayment level, and number of prescribers and pharmacies from which the patients received their medications. KEY FINDINGS: After adjustment for other factors, Filipinos [OR=0.58, 95%CI(0.45,0.74)], Native Hawaiians [OR=0.74, 95%CI(0.56,0.98)], and people of other race [OR=0.67, 95%CI(0.55,0.82)] were significantly less adherent to anti-diabetic and anti-hypertensive medications than Japanese. For cholesterol-lowering medications, all racial and ethnic groups were significantly less adherent than Japanese, except mixed race. We also found that different racial/ethnic groups tended to use different pharmacies and prescribers, particularly in rural areas. CONCLUSION: Adherence differed by race/ethnicity as well as age and region. Qualitative research involving subgroups (e.g. Filipinos, Native Hawaiians, people under age 50) is needed to identify how to adapt and enhance the effects of interventions shown to be efficacious in prior studies.
