Survey of Diagnostic and Management Practices in Small Bowel Obstruction: Individual and Generational Variation Despite Practice Guidelines.

Background: Small bowel obstruction (SBO) is a common disorder managed by surgeons. Despite extensive publications and management guidelines, there is no universally accepted approach to its diagnosis and management. We conducted a survey of acute care surgeons to elucidate their SBO practice patterns.Methods: A self-report survey of SBO diagnosis and management practices was designed and distributed by email to AAST surgeons who cared for adult SBO patients. Responses were analyzed with descriptive statistics and Chi-square test of independence at α = .05.Results: There were 201 useable surveys: 53% ≥ 50 years, 77% male, 77% at level I trauma centers. Only 35.8% reported formal hospital SBO management guidelines. Computed tomography (CT) scan was the only diagnostic exam listed as "essential" by the majority of respondents (82.6%). Following NG decompression, 153 (76.1%) would "always/frequently" administer a water-soluble contrast challenge (GC). There were notable age differences in approach. Compared to those ≥50 years, younger surgeons were less likely to deem plain abdominal films as "essential" (16.0% vs 40.2%; P < .01) but more likely to require CT scan (88.3% vs 77.6%; P = .045) for diagnosis and to "always/frequently" administer GC (84.0% vs 69.2%; P < .01). Younger surgeons used laparoscopy "frequently" more often than older surgeons (34.0% vs 21.5%, P = .05).Discussion: There is significant variation in diagnosis and management of SBO among respondents in this convenience sample, despite existing PMGs. Novel age differences in responses were observed, which prompts further evaluation. Additional research is needed to determine whether variation in practice patterns is widespread and affects outcomes.

Findings on Repeat Posttraumatic Brain Computed Tomography Scans in Older Patients With Minimal Head Trauma and the Impact of Existing Antithrombotic Use.

STUDY OBJECTIVE: Evaluate the utility of routine rescanning of older, mild head trauma patients with an initial negative brain computed tomography (CT), who is on a preinjury antithrombotic (AT) agent by assessing the rate of delayed intracranial hemorrhage (dICH), need for surgery, and attributable mortality. METHODS: Participating centers were trained and provided data collection instruments per institutional review board-approved protocols. Data were obtained from manual chart review and electronic medical record download. Adults ≥55 years seen at Level I/II Trauma Centers, between 2017 and 2019 with suspected head trauma, Glasgow Coma Scale 14 to 15, negative initial brain CT, and no other Abbreviated Injury Scale injuries >2 were identified, grouped by preinjury AT therapy (AT- or AT+) and compared on dICH rate, need for operative neurosurgical intervention, and attributable mortality using univariate analysis (α=.05). RESULTS: A total of 2,950 patients from 24 centers were enrolled; 280 (9.5%) had a repeat brain CT. In those rescanned, the dICH rate was 15/126 (11.9%) for AT- and 6/154 (3.9%) in AT+. Assuming nonrescanned patients did not suffer clinically meaningful dICH, the dICH rate would be 15/2001 (0.7%) for AT- and 6/949 (0.6%) for AT+. No surgical operations were done for dICH. All-cause mortality was 9/2950 (0.3%) and attributable mortality was 1/2950 (0.03%). The attributable death was an AT+, dICH patient whose family declined intervention. CONCLUSION: In older patients with an initial Glasgow Coma Scale of 14 to 15 and a negative initial brain CT scan, the dICH rate is low (<1%) and of minimal clinical consequence, regardless of AT use. In addition, no patient had operative neurosurgical intervention. Therefore, routine rescanning is not supported based on the results of this study.

Adherence to Antibiotic Recommendations and Infection Among Patients With Open Long-Bone Fractures: An Examination of Antibiotic Prioritization in Fracture Management.

Open fractures are at high risk of infection because of exposure of bone and tissue to the environment. Initiation of intravenous antibiotics is recommended within 1 hour of hospital arrival, although the presence of other severe injuries may lead to delays in fracture management. This retrospective study of adult patients with open long-bone fractures admitted to six level 1 trauma centers between January 1, 2018, and December 31, 2019, aimed to examine adherence to antibiotic recommendations. Associations between receiving recommendation-adherent antibiotics and patient and injury characteristics were investigated univariately and in adjusted regression analyses. The most common fracture locations among the 404 patients included were the tibia (43%) and fibula (26%). Fifty-eight percent of patients received recommendation-adherent antibiotics. After adjustment, patient demographics, comorbidities, cause of injury, and overall injury severity did not show significant associations with adherence to recommendations. Concomitant serious abdominal (adjusted odds ratio [AOR]=0.44) and spinal injuries (AOR=0.23) were associated with lower odds of receiving recommendation-adherent antibiotics. Additionally, fractures of certain locations were associated with increased odds of adherence (humerus: AOR=2.78; fibula: AOR=1.64), as were type 3 fractures (AOR=1.55). The overall infection rate was 4%, and adherence to antibiotic recommendations was not associated with infection (3% vs 5% for nonadherent, P=.34). Results suggest that although full recommendation adherence was somewhat low among this patient population, certain injury characteristics were predictive of adherence rates. Current antibiotic recommendations may benefit from consideration of how antibiotic initiation may fit into the prioritization of injury management, especially in patients with polytrauma with other severe injuries.

Factors associated with delays in medical and surgical open facial fracture management.

Objectives: Open fractures are at risk of infection because of exposure of bone and tissue to the environment. Facial fractures are often accompanied by other severe injuries, and therefore fracture management may be delayed until after stabilization. Previous studies in this area have examined timing of multiple facets of care but have tended to report on each in isolation (eg, antibiotic initiation). Methods: This was a retrospective study of adult patients admitted to five trauma centers from January 1, 2017 to March 31, 2021 with open facial fractures. Variables collected included demographics, injury mechanism, details on facial and non-facial injuries, facial fracture management (irrigation and debridement (I&D), irrigation without debridement, open reduction internal fixation (ORIF), antibiotics), and other hospital events. The study hypothesized that the presence of serious non-facial injuries would be associated with delays in facial fracture management. The primary aims were to describe open facial fracture management practices and examine factors associated with early versus delayed fracture management. A secondary aim was to describe infection rates. Early treatment was defined as within 24 hours of arrival for I&D, irrigation without debridement, and ORIF and within 1 hour for antibiotics. Results: A total of 256 patients were included. Twenty-seven percent had major trauma (Injury Severity Score ≥16). The presence of serious head injury/traumatic brain injury was associated with delayed I&D (ORearly=0.04, p<0.01), irrigation without debridement (ORearly=0.09, p<0.01), and ORIF (ORearly=0.10, p<0.01). Going to the OR within 24 hours was associated with early I&D (ORearly=377.26, p<0.01), irrigation without debridement (ORearly=13.54, p<0.01), and ORIF (ORearly=154.92, p<0.01). The infection rate was 4%. Conclusions: In this examination of multiple aspects of open facial fracture management, serious injuries to non-facial regions led to delays in surgical fracture management, consistent with the study hypothesis. Level of evidence: Level III, prognostic/epidemiological.

Hyperglycemia in nondiabetic adult trauma patients is associated with worse outcomes than diabetic patients: An analysis of 95,764 patients.

BACKGROUND: The adverse impact of acute hyperglycemia is well documented but its specific effects on nondiabetic trauma patients are unclear. The purpose of this study was to analyze the differential impact of hyperglycemia on outcomes between diabetic and nondiabetic trauma inpatients. METHODS: Adults admitted 2018 to 2019 to 46 Level I/II trauma centers with two or more blood glucose tests were analyzed. Diabetes status was determined from International Classification of Diseases-10th Rev.-Clinical Modification, trauma registry, and/or hemoglobin A1c greater than 6.5. Patients with and without one or more hyperglycemic result >180 mg/dL were compared. Logistic regression examined the effects of hyperglycemia and diabetes on outcomes, adjusting for age, sex, Injury Severity Score, and body mass index. RESULTS: There were 95,764 patients: 54% male; mean age, 61 years; mean Injury Severity Score, 10; diabetic, 21%. Patients with hyperglycemia had higher mortality and worse outcomes compared with those without hyperglycemia. Nondiabetic hyperglycemic patients had the highest odds of mortality (diabetic: adjusted odds ratio, 3.11; 95% confidence interval, 2.8-3.5; nondiabetics: adjusted odds ratio, 7.5; 95% confidence interval, 6.8-8.4). Hyperglycemic nondiabetics experienced worse outcomes on every measure when compared with nonhyperglycemic nondiabetics, with higher rates of sepsis (1.1 vs. 0.1%, p < 0.001), more SSIs (1.0 vs. 0.1%, p < 0.001), longer mean hospital length of stay (11.4 vs. 5.0, p < 0.001), longer mean intensive care unit length of stay (8.5 vs. 4.0, p < 0.001), higher rates of intensive care unit use (68.6% vs. 35.1), and more ventilator use (42.4% vs. 7.3%). CONCLUSION: Hyperglycemia is associated with increased odds of mortality in both diabetic and nondiabetic patients. Hyperglycemia during hospitalization in nondiabetics was associated with the worst outcomes and represents a potential opportunity for intervention in this high-risk group. LEVEL OF EVIDENCE: Therapeutic/care management; Level III.

The public health burden of geriatric trauma: Analysis of 2,688,008 hospitalizations from Centers for Medicare and Medicaid Services inpatient claims.

BACKGROUND: Geriatric trauma care (GTC) represents an increasing proportion of injury care, but associated public health research on outcomes and expenditures is limited. The purpose of this study was to describe GTC characteristics, location, diagnoses, and expenditures. METHODS: Patients at short-term nonfederal hospitals, 65 years or older, with ≥1 injury International Classification of Diseases, Tenth Revision, were selected from 2016 to 2019 Centers for Medicare and Medicaid Services Inpatient Standard Analytical Files. Trauma center levels were linked to Inpatient Standard Analytical Files data via American Hospital Association Hospital ID and fuzzy string matching. Demographics, care location, diagnoses, and expenditures were compared across groups. RESULTS: A total of 2,688,008 hospitalizations (62% female; 90% White; 71% falls; mean Injury Severity Score, 6.5) from 3,286 hospitals were included, comprising 8.5% of all Medicare inpatient hospitalizations. Level I centers encompassed 7.2% of the institutions (n = 236) but 21.2% of hospitalizations, while nontrauma centers represented 58.5% of institutions (n = 1,923) and 37.7% of hospitalizations. Compared with nontrauma centers, patients at Level I centers had higher Elixhauser scores (9.0 vs. 8.8) and Injury Severity Score (7.4 vs. 6.0; p < 0.0001). The most frequent primary diagnosis at all centers was hip/femur fracture (28.3%), followed by traumatic brain injury (10.1%). Expenditures totaled $32.9 billion for trauma-related hospitalizations, or 9.1% of total Medicare hospitalization expenditures and approximately 1.1% of the annual Medicare budget. The overall mortality rate was 3.5%. CONCLUSION: Geriatric trauma care accounts for 8.5% of all inpatient GTC and a similar percentage of expenditures, the most common injury being hip/femur fractures. The largest proportion of GTC occurs at nontrauma centers, emphasizing their vital role in trauma care. Public health prevention programs and GTC guidelines should be implemented by all hospitals, not just trauma centers. Further research is required to determine the optimal role of trauma systems in GTC, establish data-driven triage guidelines, and define the impact of trauma centers and nontrauma centers on GTC mortality. LEVEL OF EVIDENCE: Therapeutic/care management, Level III.

WSES/GAIS/WSIS/SIS-E/AAST global clinical pathways for patients with skin and soft tissue infections.

Skin and soft-tissue infections (SSTIs) encompass a variety of pathological conditions that involve the skin and underlying subcutaneous tissue, fascia, or muscle, ranging from simple superficial infections to severe necrotizing infections.Together, the World Society of Emergency Surgery, the Global Alliance for Infections in Surgery, the Surgical Infection Society-Europe, The World Surgical Infection Society, and the American Association for the Surgery of Trauma have jointly completed an international multi-society document to promote global standards of care in SSTIs guiding clinicians by describing reasonable approaches to the management of SSTIs.An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting evidence was shared by an international task force with different clinical backgrounds.

WSES/GAIS/SIS-E/WSIS/AAST global clinical pathways for patients with intra-abdominal infections.

Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in hospitals worldwide. The cornerstones of effective treatment of IAIs include early recognition, adequate source control, appropriate antimicrobial therapy, and prompt physiologic stabilization using a critical care environment, combined with an optimal surgical approach. Together, the World Society of Emergency Surgery (WSES), the Global Alliance for Infections in Surgery (GAIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), and the American Association for the Surgery of Trauma (AAST) have jointly completed an international multi-society document in order to facilitate clinical management of patients with IAIs worldwide building evidence-based clinical pathways for the most common IAIs. An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting information was shared by an international task force from 46 countries with different clinical backgrounds. The aim of the document is to promote global standards of care in IAIs providing guidance to clinicians by describing reasonable approaches to the management of IAIs.

COVID-19 and trauma: how social distancing orders altered the patient population using trauma services during the 2020 pandemic.

BACKGROUND: Recent studies have reported changes in trauma volumes resulting from the COVID-19 pandemic and social distancing orders (SDOs) implemented by federal and state governments. However, literature is lacking on demographic, injury and outcome patterns. METHODS: This retrospective, cross-sectional study included patients aged ≥18 years at six US level 1 trauma centers. Patients not discharged by the date of data acquisition were excluded. Demographic, injury and outcome variables were assessed across four time periods: period 1 (January 1, 2019-December 31, 2019); period 1b (March 16, 2019-June 30, 2019); period 2 (January 1, 2020-March 15, 2020); and period 3 (March 16, 2020-June 30, 2020). Patients admitted in period 3 were compared with patients presenting during all other periods. Categorical data were compared with χ2 and Fisher's exact tests, and continuous data were assessed with Student's t-tests and Wilcoxon rank-sum tests. RESULTS: We identified 18 567 patients: 12 797 patients in period 1 (including 3707 in period 1b), 2488 in period 2 and 3282 in period 3. Compared with period 1, period 3 had a statistically significant decrease in mean patient volume, increase in portion of penetrating injuries, increase in higher levels of trauma activation, change in emergency department discharge disposition locations, increase in in-hospital mortality and a shorter hospital length of stay. Comparison between period 1b and period 3 demonstrated a decrease in mean patient volume, increase in penetrating injuries, increase in high acuity trauma activations and increase in in-hospital mortality rate. From period 2 to period 3, the penetrating injuries rose from 6.7% to 9.4% (p=0.004), injury severity scale ≥25 increased from 5.9% to 7.7% (p=0.002), full trauma team activations increased from 13.7% to 16.4% (p<0.001), interhospital transfers decreased from 36.7% to 31.6% (p<0.001) and the in-hospital mortality rate increased from 3.3% to 4.2% (p=0.003). DISCUSSION: Beyond altering social interactions among people, the federal SDO is associated with changes in trauma volumes, demographics and injury patterns among patients seeking care at six level 1 hospitals during the pandemic. LEVEL OF EVIDENCE: IV, prognostic and epidemiological.

Effect of the COVID-19 pandemic on health insurance coverage among trauma patients: a study of six level I trauma centers.

BACKGROUND: Increased unemployment during the COVID-19 pandemic has likely led to widespread loss of employer-provided health insurance. This study examined trends in health insurance coverage among trauma patients during the COVID-19 pandemic, including differences in demographics and clinical characteristics by insurance type. METHODS: This was a retrospective study on adult patients admitted to six level 1 trauma centers between January 1, 2018 and June 30, 2020. The primary exposure was hospital admission date: January 1, 2018 to December 31, 2018 (Period 1), January 1, 2019 to March 15, 2020 (Period 2), and March 16, 2020 to June 30, 2020 (Period 3). Covariates included demographic and clinical variables. χ² tests examined whether the rates of patients covered by each insurance type differed between the pandemic and earlier periods. Mann-Whiney U and χ² tests investigated whether patient demographics or clinical characteristics differed within each insurance type across the study periods. RESULTS: A total of 31 225 trauma patients admitted between January 1, 2018 and June 30, 2019 were included. Forty-one per cent (n=12 651) were admitted in Period 1, 49% (n=15 258) were from Period 2, and 11% (n=3288) were from Period 3. Percentages of uninsured patients increased significantly across the three periods (Periods 1 to 3: 15%, 16%, 21%) (ptrend=0.02); however, there was no accompanying decrease in the percentages of commercial/privately insured patients (Periods 1 to 3: 40%, 39%, 39%) (ptrend=0.27). There was a significant decrease in the percentage of patients on Medicare during the pandemic period (Periods 1 to 3: 39%, 39%, 34%) (p<0.01). DISCUSSION: This study found that job loss during the COVID-19 pandemic resulted in increases of uninsured trauma patients. However, there was not a corresponding decrease in commercial/privately insured patients, as may have been expected; rather, a decrease in Medicare patients was observed. These findings may be attributable to a growing workforce during the study period, in combination with a younger overall patient population during the pandemic. LEVEL OF EVIDENCE: Retrospective, level III study.

Surgical Infection Society 2020 Updated Guidelines on the Management of Complicated Skin and Soft Tissue Infections.

Background: The Surgical Infection Society (SIS) Guidelines for the treatment of complicated skin and soft tissue infections (SSTIs) were published in October 2009 in Surgical Infections. The purpose of this project was to provide a succinct update on the earlier guidelines based on an additional decade of data. Methods: We reviewed the previous guidelines eliminating bite wounds and diabetic foot infections including their associated references. Relevant articles on the topic of complicated SSTIs from 2008-2020 were reviewed and graded individually. Comparisons were then made between the old and the new graded recommendations with review of the older references by two authors when there was disparity between the grades. Results: The majority of new studies addressed antimicrobial options and duration of therapy particularly in complicated abscesses. There were fewer updated studies on diagnosis and specific operative interventions. Many of the topics addressed in the original guidelines had no new literature to evaluate. Conclusions: Most recommendations remain unchanged from the original guidelines with the exception of increased support for adjuvant antimicrobial therapy after drainage of complex abscess and increased data for the use of alternative antimicrobial agents.

Where Did All the Appendicitis Go? Impact of the COVID-19 Pandemic on Volume, Management, and Outcomes of Acute Appendicitis in a Nationwide, Multicenter Analysis.

Objective: The study objective was to evaluate effects of the COVID-19 pandemic on rates of emergency department (ED) acute appendicitis presentation, management strategies, and patient outcomes. Summary Background Data: Acute appendicitis is the most commonly performed emergency surgery in the United States and is unlikely to improve without medical or surgical intervention. Dramatic reductions in ED visits prompted concern that individuals with serious conditions, such as acute appendicitis, were deferring treatment for fear of contracting COVID-19. Methods: Patients from 146 hospitals with diagnosed appendicitis and arrival between March 2016 and May 2020 were selected. Electronic medical records data were retrospectively reviewed to retrieve patient data. Daily admissions were averaged from March 2016 through May 2019 and compared with March 2020. April-specific admissions were compared across the 5-year pre-COVID-19 period to April 2020 to identify differences in volume, demographics, disease severity, and outcomes. Results: Appendicitis patient admissions in 2020 decreased throughout March into April, with April experiencing the fewest admissions. April 2020 experienced a substantial decrease in patients who presented with appendicitis, dropping 25.4%, from an average of 2030 patients (2016-2019) to 1516 in 2020. An even greater decrease of 33.8% was observed in pediatric patients (age <18). Overall, 77% of the 146 hospitals experienced a reduction in appendicitis admissions. There were no differences between years in percent of patients treated nonoperatively (P = 0.493) incidence of shock (P = 0.95), mortality (P = 0.24), or need for postoperative procedures (P = 0.81). Conclusions: Acute appendicitis presentations decreased significantly during the COVID-19 pandemic, while overall management and patient outcomes did not differ from previous years. Further research is needed focusing on putative explanations for decreased hospital presentations unrelated to COVID-19 infection and possible implications for surgical management of uncomplicated acute appendicitis.Keywords: acute appendicitis, COVID-19, decreasing volumes, multicenter study.

Prehospital Blood Product and Crystalloid Resuscitation in the Severely Injured Patient: A Secondary Analysis of the Prehospital Air Medical Plasma Trial.

OBJECTIVE: The aim of this study was to determine whether prehospital blood products reduce 30-day mortality in patients at risk for hemorrhagic shock compared with crystalloid only resuscitation. SUMMARY OF BACKGROUND DATA: Hemorrhage is the primary cause of preventable death after injury. Large volume crystalloid resuscitation can be deleterious. The benefits of prehospital packed red blood cells (PRBCs), plasma, or transfusion of both products among trauma patients is unknown compared with crystalloid. METHODS: Secondary analysis of the multicenter PAMPer trial was performed on hypotensive injured patients from the scene. The trial randomized 27 helicopter bases to prehospital plasma or standard resuscitation. Standard resuscitation at the sites was equally divided between crystalloid and crystalloid + PRBC. This led to 4 prehospital resuscitation groups: crystalloid only; PRBC; plasma; and PRBC+plasma. Cox regression determined the association between resuscitation groups and risk-adjusted 30-day mortality. The dose effect of resuscitation fluids was also explored. RESULTS: Four hundred seven patients were included. PRBC+plasma had the greatest benefit [hazard ratio (HR) 0.38; 95% confidence interval (95% CI) 0.26-0.55, P < 0.001], followed by plasma (HR 0.57; 95% CI 0.36-0.91, P = 0.017) and PRBC (HR 0.68; 95% CI 0.49-0.95, P = 0.025) versus crystalloid only. Mortality was lower per-unit of PRBC (HR 0.69; 95% CI 0.52-0.92, p = 0.009) and plasma (HR 0.68; 95% CI 0.54-0.88, P = 0.003). Crystalloid volume was associated with increased mortality among patients receiving blood products (HR 1.65; 95% CI 1.17-2.32, P = 0.004). CONCLUSION: Patients receiving prehospital PRBC+plasma had the greatest mortality benefit. Crystalloid only had the worst survival. Patients with hemorrhagic shock should receive prehospital blood products when available, preferably PRBC+plasma. Prehospital whole blood may be ideal in this population.

2020 update of the WSES guidelines for the management of acute colonic diverticulitis in the emergency setting.

Acute colonic diverticulitis is one of the most common clinical conditions encountered by surgeons in the acute setting. An international multidisciplinary panel of experts from the World Society of Emergency Surgery (WSES) updated its guidelines for management of acute left-sided colonic diverticulitis (ALCD) according to the most recent available literature. The update includes recent changes introduced in the management of ALCD. The new update has been further integrated with advances in acute right-sided colonic diverticulitis (ARCD) that is more common than ALCD in select regions of the world.

Necrotizing Soft Tissue Infections: A Focused Review of Pathophysiology, Diagnosis, Operative Management, Antimicrobial Therapy, and Pediatrics.

Background: Necrotizing fasciitis is a major health problem throughout the world. The purpose of this review is to assist providers with the care of these patients through a better understanding of the pathophysiology and management options. Methods: This is a collaborative review of the literature between members of the Surgical Infection Society of North America and World Society of Emergency Surgery. Results: Necrotizing fasciitis continues to be difficult to manage with the mainstay being early diagnosis and surgical intervention. Recognition of at-risk populations assists with the initiation of treatment, thereby impacting outcomes. Conclusions: Although there are some additional treatment strategies available, surgical debridement and antimicrobial therapy are central to the successful eradication of the disease process.

Role of Empiric Anti-Fungal Therapy in the Treatment of Perforated Peptic Ulcer Disease: Review of the Evidence and Future Directions.

Background: Peptic ulcer disease (PUD) affects four million people worldwide. Perforated peptic ulcer (PPU) occurs in less than 15% of cases but is associated with significant morbidity and mortality rates. Administration of antibiotics is standard treatment for gastrointestinal perforations, including PPU. Although fungal growth is common in peritoneal fluid cultures from patients with PPU, current data suggest empiric anti-fungal therapy fails to improve outcomes. To examine the role of anti-fungal agents in the treatment of PPU, the Surgical Infection Society hosted an Update Symposium at its 37th Annual Meeting. Here, we provide a synopsis of the symposium's findings and a brief review of prospective and retrospective reports on the subject. Methods: A search of Pubmed/MEDLINE, EMBASE, and the Cochrane Library was performed between January 1, 2000, and November 1, 2018, comparing outcomes of PPU following empiric anti-fungal treatment versus no anti-fungal therapy. We used the search terms "perforated peptic ulcer," "gastroduodenal ulcer," "anti-fungal," and "perforated" or "perforation." Results: There are no randomized clinical trials comparing outcomes specifically for patients with PPU treated with or without empiric anti-fungal therapy. We identified one randomized multi-center trial evaluating outcomes for patients with intra-abdominal perforations, including PPU, that were treated with or without empiric anti-fungal therapy. We identified one single-center prospective series and three additional retrospective studies comparing outcomes for patients with PPU treated with or without empiric anti-fungal therapy. Conclusion: The current evidence reviewed here does not demonstrate efficacy of anti-fungal agents in improving outcomes in patients with PPU. As such, we caution against the routine use of empiric anti-fungal agents in these patients. Further studies should help identify specific subpopulations of patients who might derive benefit from anti-fungal therapy and help define appropriate treatment regimens and durations that minimize the risk of resistance, adverse events, and cost.

Actinomyces turicensis Necrotizing Soft-Tissue Infection of the Thigh in a Diabetic Male.

Background: Necrotizing soft-tissue infections are a devastating infection that is rarely caused by Actinomyces spp. Case Report: A 45-year-old obese previously healthy male presented to the emergency department with diabetic ketoacidosis. The patient developed systemic signs of infections and right medial thigh pain subsequently diagnosed as a necrotizing soft-tissue infection. Successful treatment included prompt surgical intervention and initiation of broad-spectrum antimicrobial drugs. Conclusion: Actinomyces turicensis may be the pathogen causing certain necrotizing soft-tissue infections. Clinicians should consider the possibility that this organism represents a true pathogen and not colonization/contamination.

The EGS grading scale for skin and soft-tissue infections is predictive of poor outcomes: a multicenter validation study.

INTRODUCTION: Over the last 5 years, the American Association for the Surgery of Trauma has developed grading scales for emergency general surgery (EGS) diseases. In a previous validation study using diverticulitis, the grading scales were predictive of complications and length of stay. As EGS encompasses diverse diseases, the purpose of this study was to validate the grading scale concept against a different disease process with a higher associated mortality. We hypothesized that the grading scale would be predictive of complications, length of stay, and mortality in skin and soft-tissue infections (STIs). METHODS: This multi-institutional trial encompassed 12 centers. Data collected included demographic variables, disease characteristics, and outcomes such as mortality, overall complications, and hospital and ICU length of stay. The EGS scale for STI was used to grade each infection and two surgeons graded each case to evaluate inter-rater reliability. RESULTS: 1170 patients were included in this study. Inter-rater reliability was moderate (kappa coefficient 0.472-0.642, with 64-76% agreement). Higher grades (IV and V) corresponded to significantly higher Laboratory Risk Indicator for Necrotizing Fasciitis scores when compared with lower EGS grades. Patients with grade IV and V STI had significantly increased odds of all complications, as well as ICU and overall length of stay. These associations remained significant in logistic regression controlling for age, gender, comorbidities, mental status, and hospital-level volume. Grade V disease was significantly associated with mortality as well. CONCLUSION: This validation effort demonstrates that grade IV and V STI are significantly predictive of complications, hospital length of stay, and mortality. Though predictive ability does not improve linearly with STI grade, this is consistent with the clinical disease process in which lower grades represent cellulitis and abscess and higher grades are invasive infections. This second validation study confirms the EGS grading scale as predictive, and easily used, in disparate disease processes. LEVEL OF EVIDENCE: Prognostic/Epidemiologic retrospective multicenter trial, level III.

Role of ED crowding relative to trauma quality care in a Level 1 Trauma Center.

OBJECTIVE: Trauma Quality Improvement Program participation among all trauma centers has shown to improve patient outcomes. We aim to identify trauma quality events occurring during the Emergency Department (ED) phase of care. METHODS: This is a single-center observational study using consecutively registered data in local trauma registry (Jan 1, 2016-Jun 30, 2017). Four ED crowding scores as determined by four different crowding estimation tools were assigned to each enrolled patient upon arrival to the ED. Patient related (age, gender, race, severity of illness, ED disposition), system related (crowding, night shift, ED LOS), and provider related risk factors were analyzed in a multivariate logistic regression model to determine associations relative to ED quality events. RESULTS: Total 5160 cases were enrolled among which, 605 cases were deemed ED quality improvement (QI) cases and 457 cases were ED provider related. Similar percentages of ED QI cases (10-12%) occurred across the ED crowding status range. No significant difference was appreciated in terms of predictability of ED QI cases relative to different crowding status after adjustment for potential confounders. However, an adjusted odds ratio of 1.64 (95% CI, 1.17-2.30, p < 0.01) regarding ED LOS ≥2 h predictive of ED related quality issues was noted when analyzed using multivariate logistic regression. CONCLUSION: Provider related issues are a common contributor to undesirable outcomes in trauma care. ED crowding lacks significant association with poor trauma quality care. Prolonged ED LOS (≥2 h) appears to be linked with unfavorable outcomes in ED trauma care.
