Advanced Surgical Skills for Exposure in Trauma (ASSET) course improves military surgeon confidence.

OBJECTIVE: Active duty military surgeons often have limited trauma surgery experience prior to deployment. Consequently, military-civilian training programs have been developed at high-volume trauma centers to evaluate and maintain proficiencies. Advanced Surgical Skills for Exposure in Trauma (ASSET) was incorporated into the predeployment curriculum at the Army Trauma Training Detachment in 2011. This is the first study to assess whether military surgeons demonstrated improved knowledge and increased confidence after taking ASSET. DESIGN: Retrospective cohort study. SETTING: Quaternary care hospital. PATIENTS AND PARTICIPANTS: Attending military surgeons who completed ASSET between July 2011 and October 2020. MAIN OUTCOME MEASURE(S): Pre- and post-course self-reported comfort level with procedures was converted from a five-point Likert scale to a percentage and compared using paired t-tests. RESULTS: In 188 military surgeons, the median time in practice was 3 (1-8) years, with specialties in general surgery (52 percent), orthopedic surgery (29 percent), trauma (7 percent), and other disciplines (12 percent). The completed self-evaluation response rate was 80 percent (n = 151). The self-reported comfort level for all body regions improved following course completion (p < 0.001): chest (27 percent), neck (23 percent), upper extremity (22 percent), lower extremity (21 percent), and abdomen/pelvis (19 percent). The overall score on the competency test improved after completion of ASSET, with averages increasing from 62 ± 18 percent pretest to 71 ± 13 percent post-test (p < 0.001). CONCLUSIONS: After taking the ASSET course, military surgeons demonstrated improved knowledge and increased confidence in the operative skills taught in the course. The ASSET course may provide sustainment of knowledge and confidence if used at regular intervals to maintain trauma skills and deployment readiness.

Coaching Program to Address Burnout, Well-Being, and Professional Development in Pediatric Surgery Trainees: A Randomized Controlled Trial.

OBJECTIVE: To assess impact of participation in a positive psychology coaching program on trainee burnout and well-being. BACKGROUND: Coaching using principles of positive psychology can improve well-being and reduce physician burnout. We hypothesized that participation in a coaching program would improve pediatric surgery trainee well-being. METHODS: With IRB approval, a coaching program was implemented during the COVID-19 pandemic (9/2020-7/2021) in the American Pediatric Surgical Association. Volunteer pediatric surgery trainees (n=43) were randomized to receive either one-on-one quarterly virtual coaching (n=22) from a pediatric surgeon trained in coaching skills or wellness reading materials (n=21). Participants completed pre- and post-study surveys containing validated measures including PERMA (positive emotion, engagement, relationships, meaning, accomplishment), professional fulfillment, burnout, self-valuation, gratitude, coping skills, and workplace experiences. Results were analyzed using Wilcoxon rank sum test, Kruskal-Wallis test, or chi-square test. RESULTS: Forty trainees (93%) completed both the baseline and year-end surveys and were included in the analysis. Twenty-five (64%) were female, mean age 35.7 (SD 2.3), 65% first-year fellows. Coached trainees showed an improved change in PERMA (P=0.034), burnout (P=0.024), and gratitude (P=0.03) scores from pre- to post-coaching compared to non-coached trainees. Coping skills also improved. More coaching sessions was associated with higher self-valuation scores (P=0.042), and more opportunities to reflect was associated with improved burnout and self-valuation. CONCLUSIONS: Despite the stress and challenges of medicine during COVID-19, a virtual positive psychology coaching program provided benefit in well-being and burnout to pediatric surgery trainees. Coaching should be integrated into existing wellness programs to support acquisition of coping skills that help trainees cope with the stressors they will face during their careers.

Improper Restraint Use in Fatal Pediatric Motor Vehicle Collisions.

PURPOSE: Motor vehicle collisions (MVC) are the second leading cause of death in children and adolescents, but appropriate restraint use remains inadequate. Our previous work shows that about half of pediatric MVC victims presenting to our trauma center were unrestrained. This study evaluates restraint use among children and adolescents who did not survive after MVC. We hypothesize that restraint use is even lower in this population than in pediatric MVC patients who reached our trauma center. METHODS: We reviewed the local Medical Examiner's public records for fatal MVCs involving decedents <19 years old from 2010 to 2021. When restraint use was not documented, local Fire Rescue public records were cross-referenced. Patients were excluded if restraint use was still unknown. Age, demographics, and restraint use were compared using standard statistical methods. RESULTS: Of 199 reviewed cases, 92 met selection criteria. Improper restraint use was documented in 72 patients (78%). Most decedents were White (72% versus 28% Black) and male (74%), with a median age of 17 years [15-18]. Improper restraint use was more common among Black (92% vs 73% White, p = 0.040) and male occupants (85% vs 58% female, p = 0.006). Improper restraint use was lower in the Hispanic population (73%) compared to non-Hispanic individuals (89%), but this difference was not statistically significant (p = 0.090). CONCLUSION: Most pediatric patients who die from MVCs in our county are improperly restrained. While male and Black patients are especially high-risk, the overall dismal rates of restraint use in our pediatric population present an opportunity to improve injury prevention measures. TYPE OF STUDY: Retrospective Comparative Study. LEVEL OF EVIDENCE: Level III.

Admission to a Verified Pediatric Trauma Center is Associated With Improved Outcomes in Severely Injured Children.

BACKGROUND: Previous studies have shown improved survival for severely injured adult patients treated at American College of Surgeons verified level I/II trauma centers compared to level III and undesignated centers. However, this relationship has not been well established in pediatric trauma centers (PTCs). We hypothesize that severely injured children will have lower mortality at verified level I/II PTCs compared to centers without PTC verification. METHODS: All patients 1-15 years of age with ISS >15 in the 2017-2019 American College of Surgeons Trauma Quality Programs (ACS TQP) dataset were reviewed. Patients with pre-hospital cardiac arrest, burns, and those transferred out for ongoing inpatient care were excluded. Logistic regression models were used to assess the effects of pediatric trauma center verification on mortality. RESULTS: 16,301 patients were identified (64 % male, median ISS 21 [17-27]), and 60 % were admitted to verified PTCs. Overall mortality was 6.0 %. Mortality at centers with PTC verification was 5.1 % versus 7.3 % at centers without PTC verification (p < 0.001). After controlling for injury mechanism, sex, age, pediatric-adjusted shock index (SIPA), ISS, arrival via interhospital transfer, and adult trauma center verification, pediatric level I/II trauma center designation was independently associated with decreased mortality (OR 0.72, 95 % CI 0.61-0.85). CONCLUSIONS: Treatment at ACS-verified pediatric trauma centers is associated with improved survival in critically injured children. These findings highlight the importance of PTC verification in optimizing outcomes for severely injured pediatric patients and should influence trauma center apportionment and prehospital triage. LEVEL OF EVIDENCE: Level IV - Retrospective review of national database.

Immediate Versus Delayed Surgical Management of Infant Cryptorchidism With Inguinal Hernia.

INTRODUCTION: Cryptorchidism is commonly treated with orchiopexy at 6-12 months of age, often allowing time for undescended testicle(s) (UT) to descend spontaneously. However, when an inguinal hernia (IH) is also present, some surgeons perform orchiopexy and inguinal hernia repair (IHR) immediately rather than delaying surgery. We hypothesize that early surgical intervention provides no benefit for newborns with both IH and UT. METHODS: The Nationwide Readmissions Database was used to identify newborns with diagnoses of both IH and UT from 2010 to 2014. Patients were stratified by management: IHR performed on initial admission (Repair) or not (Deferral). Demographics, outcomes, and complications were compared. Results were weighted for national estimates. RESULTS: We analyzed 1306 newborns (64% premature) diagnosed with both IH and UT. IHR was performed at index admission in 30%. Repair was more common in premature babies (43% vs. 8% full-term, p < 0.001) and patients with congenital anomalies (33% vs. 27% without congenital anomaly, p = 0.012). There was no difference in readmission rates. Repair patients had higher rates of orchiectomy than did Deferral. No Deferral patients were readmitted for bowel resection, and <1% were readmitted for orchiectomy or hernia incarceration. CONCLUSION: In newborns with UT and IH, immediate repair is not associated with improved outcomes. Even with incarceration on initial presentation, rates of readmission with incarceration or bowel compromise for patients who undergo Deferral of surgery are minimal. Moreover, Repair newborns have higher rates of orchiectomy. We found no benefit to early operative intervention; thus, we recommend waiting until 6-12 months of age to reassess for surgery. LEVEL OF EVIDENCE: Level III TYPE OF STUDY: Retrospective Comparative Study.

Using intent to get ahead of pediatric cranial firearm injuries.

OBJECTIVE: Pediatric firearm injuries (PFI) are a public health crisis. Little is known about how injury intent may influence the outcome of pediatric cranial firearm injuries (PCFI). The current study sought to compare demographics and outcomes of PCFI based on intent of injury. METHODS: The Nationwide Readmission Database (2010-2014) was queried to identify patients <18 years old with PCFI. Demographics and outcomes were compared by injury intent (assault, self-inflicted, unintentional), and results were weighted for national estimates to create a population-based cohort study. RESULTS: There were 1,365 cases of PCFI identified for an incidence of 11% of all PFI. The majority of patients were male (83 %), >13 years (81 %), and had an injury severity score >15 (79 %). Overall PCFI mortality was 43 %, compared to 6 % for all PFI. Assault was the most common intent (51 %), followed by self-inflicted (25 %), and unintentional (24 %). Assault was more likely to occur in patients from low-income households (61 % vs. 31 % self-inflicted vs. 42 % unintentional), p < 0.001. Unintentional injuries occurred in those <13 years old (40 % vs. 12 % assault vs. 16 % self-inflicted) and more often resulted in facial fracture (19 % vs. 11 % vs. 13 %), all p < 0.001. Readmission rate within the year was 21 %. The majority (56 %) of readmissions were unplanned, and the rate was highest for assault (77 % vs. <1 % self-inflicted vs. 44 % unintentional, p < 0.001). CONCLUSIONS: PCFI are associated with significant morbidity and mortality. Demographics and outcomes vary by intent of injury; knowledge of these patterns can direct future interventions to reduce injuries and impact outcomes.

Timing of Pediatric Incarcerated Inguinal Hernia Repair: A Review of Nationwide Readmissions Data.

INTRODUCTION: In pediatric patients, incarcerated inguinal hernias are often repaired on presentation. We hypothesize that in appropriate patients, repair may be safely deferred. METHODS: The Nationwide Readmissions Database was used to identify pediatric patients (aged < 18 y) with incarcerated inguinal hernia from 2010 to 2014. Patients were stratified by management approach (Early Repair versus Deferral). Overall frequencies of these operative strategies were calculated. Propensity score matching was then performed to control for patient age, comorbidities, perinatal conditions, and congenital anomalies. Outcomes including complications, surgical procedures, and readmissions were compared. Outpatient surgeries were not assessed. RESULTS: Among 6148 total patients with incarcerated inguinal hernia, the most common strategy was to perform Early Repair (88% versus 12% Deferral). Following propensity score matching, the cohort included 1288 patients (86% male, average age 1.7 ± 4.1 years). Deferral was associated with equivalent rates of readmission within one year (13% versus 15%, P = 0.143), but higher readmissions within the first 30 days (7% versus 3%, P = 0.002) than Early Repair. Deferral patients had lower rates of orchiectomy (2% versus 5%, P = 0.001), wound infections (< 2% versus 2%, P = 0.020), and other infections (7% versus 15%, P < 0.001). The frequency of other complications including bowel resection, oophorectomy, testicular atrophy, sepsis, and pneumonia were equivalent between groups. Three percent of Deferrals had a diagnosis of incarceration on readmission. CONCLUSIONS: Deferral of incarcerated inguinal hernia repair at index admission is associated with higher rates of hospital readmissions within the first 30 days but equivalent readmission within the entire calendar year. These patients are at risk of repeat incarceration but have significantly lower rates of orchiectomy than their counterparts who undergo inguinal hernia repair at the index admission. We propose that prospective studies be performed to identify good candidates for Elective Deferral following manual reduction and overnight observation. Such studies must capture outpatient surgical outcomes.

Outcomes of Incidental Appendectomy During Ovarian Operations in a National Pediatric Cohort.

INTRODUCTION: The utility of incidental appendectomy (IA) during many ovarian operations has not been evaluated in the pediatric population. This study sought to compare outcomes after ovarian surgery with IA in the pediatric population. METHODS: Females (≤20 y old) undergoing ovarian surgeries (oophorectomy, detorsion and/or drainage) were identified from the Nationwide Readmissions Database (2016-2018). Those with appendicitis were excluded. A propensity score-matched analysis (PSMA) with 46 covariates (demographics, comorbidities, hospitalization factors, etc.) was performed between those receiving ovarian surgery with or without IA. RESULTS: There were 13,202 females (median age 17 [IQR 14-20] y old) who underwent oophorectomy (90%), detorsion (26%), and/or ovarian drainage (13%). There were more episodes of torsion in the PSMA cohort receiving ovarian surgery alone (17% versus 10% IA; P = 0.016), while other indications (ovarian mass, cyst) were similar. Open (66% versus 34% laparoscopic) IAs were more frequent. Length of stay (LOS) was longer for those undergoing IA (3 [2-4] versus 2 [2-4] days ovarian surgery alone; P < 0.001). There was a higher rate of postoperative GI complications in the IA cohort. Subgroup analysis of those undergoing laparoscopic operations demonstrated no difference in LOS or postoperative complications between patients undergoing IA or not. CONCLUSIONS: These data indicate that IA in pediatric ovarian operations is associated with longer LOS and higher GI postoperative complications. However, laparoscopic IA was not associated with higher cost, complications, LOS, or readmissions. This suggests that IA performed during ovarian surgeries in select patients may be cost-effective and worthy of future study.

Nationwide Outcomes After Thoracoscopic Versus Open Resection of Congenital Pulmonary Airway Malformations in Newborns.

Purpose: Elective resection of congenital pulmonary airway malformations (CPAM) has been debated for decades and varies significantly between individual surgeons. However, few studies have compared outcomes and costs associated with thoracoscopic and open thoracotomy approaches on a national level. This study sought to compare nationwide outcomes and resource utilization in infants undergoing elective lung resection for CPAM. Materials and Methods: The Nationwide Readmission Database was queried from 2010 to 2014 for newborns who underwent elective surgical resection of CPAM. Patients were stratified by operative approach (thoracoscopic versus open). Demographics, hospital characteristics, and outcomes were analyzed using standard statistical tests. Results: A total of 1716 newborns with CPAM were identified. Elective readmission for pulmonary resection was performed in 12% (n = 198), with 63% of resections completed at a different hospital than the newborn stay. Most resections were thoracoscopic (75%), compared to only 25% via thoracotomy. Infants treated with thoracoscopic resection were more often male (78% versus 62% open, P = .040) and were older at the time of resection. Patients who had an open thoracotomy experienced a higher rate of serious complications (40% versus 10% thoracoscopic, P < .001), including postoperative hemorrhage, tension pneumothorax, and pulmonary collapse. Readmission costs were higher for infants treated via thoracotomy (P < .001). Conclusion: Thoracoscopic lung resection for CPAM is associated with lower cost and fewer postoperative complications than thoracotomy. Most resections are performed at different hospitals than the place of birth, which may affect long-term outcomes from single institutional studies. These findings may be used to address costs and improve future evaluations of elective CPAM resections.

Examination Scores but not Clinical Performance Correlate With Duration of Preclinical Didactic Time: A Synchronous Comparison of Second- Versus Third-Year Medical Students on the Surgery Clerkship.

OBJECTIVE: Numerous institutions have reduced preclinical didactic time to facilitate earlier clinical exposure during the second year of medical education. However, the effects that shortened preclinical education may have on performance in the surgery clerkship are unclear. This study aims to compare the clinical and examination performance of second- (MS2) and third-year (MS3) students synchronously completing an identical surgery clerkship. DESIGN: All students completing the surgery clerkship (identical didactics, examinations, clinical rotations, etc.) were included. MS3s received 24 months of preclinical education, whereas MS2s received 14 months. Performance outcomes included weekly quizzes based on lectures, NBME Surgery Shelf Exam, numeric clinical evaluations, objective structured clinical examination (OSCE) scores, and overall clerkship grades. SETTING: University of Miami Miller School of Medicine. PARTICIPANTS: All second- (MS2) and third-year (MS3) medical students completing the Surgery Clerkship over 1 year (n = 395). RESULTS: There were 199 MS3 (50%) and 196 MS2 (50%) students. MS3s demonstrated higher median shelf exams (77% vs 72% MS2s), weekly quiz score averages (87% vs 80% MS2s), clinical evaluations (96% vs 95% MS2s), and overall clerkship grades (89% vs 87% MS2s), all p < 0.020. There was no difference in median OSCE performance (both 92%; p = 0.499). A greater proportion of MS3 students performed in the highest 50% of weekly quiz scores (57% vs 43% MS2), NBME shelf exams (59% vs 39% MS2), and overall clerkship grades (45% vs 37% MS2), all p < 0.010. No significant difference in the proportion of students placing in the top 50% of clinical parameters including the OSCE (48% MS3 vs 46% MS2; p = 0.106) and clinical evaluations (45% MS3 vs 38%; p = 0.185) was observed. CONCLUSIONS: Although the duration of preclerkship education may correspond to examination scores, MS2s and MS3s perform similarly on clinical metrics. Future strategies to enhance available preclinical didactic time and preparation for examinations are needed.

Primary Spontaneous Pneumothorax Outcomes in Children: A National Analysis.

OBJECTIVE: Considerable variation in primary spontaneous pneumothorax (PSP) management exists in the pediatric population. This study aims to compare nationwide outcomes of children with PSP. METHODS: The Nationwide Readmissions Database (2016 to 2018) was used to identify patients 1 to 18 years old with PSP. Trauma, secondary pneumothoraces, and elective admissions were excluded. Demographics and complications were compared among patients undergoing initial nonoperative management (NOM; observation or percutaneous drainage) or operative resection using standard statistical tests. RESULTS: A total of 3,890 patients were identified with PSP (median age, 16 [interquartile range 14 to 17] years). Most (78%) underwent NOM, of which 17% failed requiring operative resection. Of the intent-to-treat cohort, 28% failed NOM during index admission or required repeat percutaneous drainage or operative resection on readmission. Patients treated by NOM had higher 30-day and overall readmission rates compared with operative resection (all P < 0.001). Ipsilateral recurrent pneumothorax was higher in those receiving NOM (13% vs 3%, P < 0.001). Patients from the lowest median household income quartile more frequently received NOM compared with the highest income quartile (82% vs 76%) with more readmissions. CONCLUSIONS: Patients with PSP who underwent initial NOM experienced higher readmission rates than those receiving operative resection. Furthermore, socioeconomic status was associated with the utilization of nonoperative versus operative management.

Burn excision within 48 hours portends better outcomes than standard management: A nationwide analysis.

BACKGROUND: Previous studies have debated the optimal time to perform excision and grafting of second- and third-degree burns. The current consensus is that excision should be performed before the sixth hospital day. We hypothesize that patients who undergo excision within 48 hours have better outcomes. METHODS: The American College of Surgeons Trauma Quality Programs data set was used to identify all patients with at least 10% total body surface area second- and third-degree burns from years 2017 to 2019. Patients with other serious injuries (any Abbreviated Injury Scale, >3), severe inhalational injury, prehospital cardiac arrest, and interhospital transfers were excluded. International Classification of Diseases, Tenth Revision , procedure codes were used to ascertain time of first excision. Patients who underwent first excision within 48 hours of admission (early excision) were compared with those who underwent surgery 48 to 120 hours from admission (standard therapy). Propensity score matching was performed to control for age and total body surface area burned. RESULTS: A total of 2,270 patients (72% male) were included in the analysis. The median age was 37 (23-55) years. Early excision was associated with shorter hospital length of stay (LOS), and intensive care unit LOS. Complications including deep venous thrombosis, pulmonary embolism, ventilator-associated pneumonia, and catheter-associated urinary tract infection were significantly lower with early excision. There was no significant difference in mortality. CONCLUSION: Performance of excision within 48 hours is associated with shorter hospital LOS and fewer complications than standard therapy. We recommend taking patients for operative debridement and temporary or, when feasible, permanent coverage within 48 hours. Prospective trials should be performed to verify the advantages of this treatment strategy. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Pediatric Pedestrian Injuries: Striking Too Close to Home.

BACKGROUND: Pediatric pedestrian injuries (PPI) are a major public health concern. This study utilized geospatial analysis to characterize the risk and injury severity of PPI. METHODS: A retrospective chart review of PPI patients (age < 18) from a level 1 trauma center was performed (2013-2020). A geographic information system geocoded injury location to home and other public landmarks. Incidents were aggregated to zip codes and the Local Indicators of Spatial Association statistic tested for spatial clustering of injury rates per 10,000 children. Predictors for increased injury severity were assessed by logistic regression. RESULTS: PPI encompassed 6% (n = 188) of pediatric traumas. Most patients were black (54%), male (58%), >13 years (56%), and with Medicaid insurance (68%). Nine zip codes comprised a statistically significant cluster of PPI. Nearly half (40%) occurred within a quarter mile of home; 7% occurred at home. Most (65%) PPI occurred within 1 mile of a school, and 45% occurred within a quarter mile of a park. Nearly all (99%) PPI occurred within a quarter mile of a major intersection and/or roadway. Using admission to ICU as a marker for injury severity, farther distance from home (OR 1.060, 95% CI 1.001-1.121, p = 0.045) and age <13 years (3.662, 95% CI 1.854-7.231, p < 0.001) were independent predictors of injury severity. CONCLUSIONS: There are significant sociodemographic disparities in PPI. Most injuries occur near patients' homes and other public landmarks. Multidisciplinary injury prevention collaboration can help inform policymakers, direct local safety programs, and provide a model for PPI prevention at the national level. LEVEL OF EVIDENCE: Level IV.

Outcomes After Ladd Procedures for Intestinal Malrotation in Newborns with Heterotaxy Syndrome.

PURPOSE: Intestinal malrotation may be asymptomatic in patients with heterotaxy syndrome (HS), and whether these newborns benefit from prophylactic Ladd procedures is unknown. This study sought to uncover nationwide outcomes of newborns with HS receiving Ladd procedures. METHODS: Newborns with malrotation were identified from the Nationwide Readmission Database (2010-2014) and stratified into those with and without HS utilizing ICD-9CM codes for situs inversus (759.3), asplenia or polysplenia (759.0), and/or dextrocardia (746.87). Outcomes were analyzed using standard statistical tests. RESULTS: 4797 newborns with malrotation were identified, of which 16% had HS. Ladd procedures were performed in 70% overall and more common in those without heterotaxy (73% vs. 56% HS). Ladd procedures in newborns with heterotaxy were associated with higher complications compared to those without HS including surgical site reopening (8% vs. 1%), sepsis (9% vs. 2%), infections (19% vs. 11%), venous thrombosis (9% vs. 1%), and prolonged mechanical ventilation (39% vs. 22%), all p < 0.001. HS newborns were less frequently readmitted with bowel obstructions (0% vs. 4% without HS, p < 0.001) with no readmissions for volvulus in either group. CONCLUSION: Ladd procedures in newborns with heterotaxy were associated with increased complications and cost without differences in rates of volvulus and bowel obstruction on readmission. TYPE OF STUDY: Retrospective Comparative. LEVEL OF EVIDENCE: III.

Nationwide Outcomes of Immediate Versus Staged Surgery for Newborns with Rectosigmoid Hirschsprung Disease.

PURPOSE: Debate exists on whether patients with Hirschsprung Disease (HD) should undergo immediate resection during their newborn hospitalization or undergo a staged procedure. This study sought to compare postoperative outcomes among newborns receiving immediate versus staged surgery for rectosigmoid HD. METHODS: The Nationwide Readmission Database was queried (2016-2018) for newborns with HD who underwent surgical resection during their newborn hospitalization (immediate) versus planned readmission (staged). Those who did not receive rectal biopsy or had long-segment or total colonic HD were excluded. A propensity score-matched analysis (PSMA) of patients receiving either surgery was constructed utilizing >70 comorbidities. Outcomes were analyzed using standard statistical tests. RESULTS: 1,048 newborns with HD were identified (56% immediate vs. 44% staged). Staged resection was associated with higher total hospitalization cost ($56,642 vs. $50,166 immediate), p = 0.014. After PSMA, the staged cohort was more likely to require home healthcare at discharge and experience unplanned readmission (40% vs. 23%). These patients experienced more gastrointestinal complications (40% vs. 22%) on readmission, especially Hirschsprung-associated enterocolitis (35% vs. 20%). CONCLUSION: Newborns receiving staged procedures for HD experience higher rates of unplanned readmission complications and incur higher hospitalization costs. This information should be utilized to defray healthcare utilization costs for newborns with HD. TYPE OF STUDY: Retrospective Comparative. LEVEL OF EVIDENCE: III.

Examining the Definition of Ventilator-Associated Pneumonia in the Trauma Setting: A Single-Center Analysis.

Background: Ventilator associated pneumonia (VAP) is defined by the American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) using laboratory findings, pathophysiologic signs/symptoms, and imaging criteria. However, many critically ill trauma patients meet the non-specific laboratory and sign/symptom thresholds for VAP, so the TQIP designation of VAP depends heavily upon imaging evidence. We hypothesized that physician opinions widely vary regarding chest radiograph findings significant for VAP. Patients and Methods: The TQIP Spring 2021 Benchmark Report (BR) was used to identify 14 patients with VAP at an academic Level 1 Trauma Center. Critically ill trauma patients (n = 7) who spent at least four days intubated and met TQIP's laboratory and sign/symptom thresholds for VAP but did not appear as VAPs on the BR comprised the control group. For each deidentified patient, four successive chest radiographic images were compiled and arranged chronologically. Cases and controls were randomly arranged in digital format. Blinded physicians (n = 27) were asked to identify patients with VAP based solely on imaging evidence. Results: Radiographic evidence of VAP was highly subjective (Krippendorff α = 0.134). Among physicians of the same job description, inter-rater reliability remained low (α = 0.137 for trauma attending physicians; α = 0.141 for trauma fellows; α = 0.271 for radiologists). When majority judgment was compared to the TQIP BR, there was disagreement between the two tests (Cohen κ = -0.071; sensitivity, 64.3%; specificity, 28.6%). Conclusions: Current definitions of VAP rely on subjective imaging interpretation and ignore the reality that there are numerous explanations for opacities on CXR. The inconsistency of physicians' imaging interpretation and protean physiologic findings for VAP in trauma patients should preclude the current definition of VAP from being used as a quality improvement metric in TQIP.

Underutilization of laparoscopy for ovarian surgeries in the pediatric population: A nationwide analysis.

PURPOSE: Oophorectomy and ovarian detorsion are some of the most frequent operations performed in the female pediatric population. Despite the advent of laparoscopy, many surgeons continue to utilize open surgical approaches in these patients. This study sought to compare nationwide trends and postoperative outcomes in laparoscopic and open ovarian operations in the pediatric population. METHODS: Females less than 21 years old who underwent ovarian operations (oophorectomy, detorsion, and/or drainage) from 2016 to 2017 were identified from the Nationwide Readmissions Database. Patients were stratified by surgical approach (laparoscopic or open). Hospital characteristics and outcomes were compared using standard statistical tests. RESULTS: There were 13,202 females (age 17 [14-20] years) who underwent open (59%) or laparoscopic (41%) ovarian operations. The most common indications for surgery were ovarian mass (48%), cyst (36%), and/or torsion (19%) for which oophorectomy (88%), detorsion (26%), and drainage (13%) were performed most frequently. The open approach was utilized more frequently for oophorectomy (95% vs. 77% laparoscopic) and detorsion (33% vs. 16% laparoscopic), both p < 0.001. A greater proportion of laparoscopic procedures were performed at large (67% vs. 61% open), teaching (82% vs. 76% open) hospitals in patients with private insurance (47% vs. 42% open), all p < 0.001. Patients undergoing open procedures had significantly higher index length of stay (LOS) and rates of wound infections. Thirty-day and overall readmission rates, as well as overall readmission costs, were higher in patients who received open surgeries. CONCLUSIONS: Despite fewer overall complications, decreased cost, fewer readmissions, and shorter LOS, laparoscopic approaches are underutilized for pediatric ovarian procedures. TYPE OF STUDY: Retrospective Comparative. LEVEL OF EVIDENCE: Level III.

Improved survival for severely injured patients receiving massive transfusion at US teaching hospitals: A nationwide analysis.

BACKGROUND: Previous studies have shown improved survival for patients treated at American College of Surgeons (ACS)-verified level I trauma centers compared with level II, level III, and undesignated centers. This mortality difference is more pronounced in severely injured patients. However, a survival benefit for severely injured trauma patients has not been established at teaching institutions compared with nonteaching centers. Because massive transfusion (MT) is associated with high mortality, we hypothesize that patients receiving MT have lower mortality at teaching hospitals than at nonteaching hospitals. METHODS: All adult ACS Trauma Quality Improvement Program-eligible patients who underwent MT, defined as >10 U of packed red blood cells in the first 4 hours after arrival, in the 2019 ACS Trauma Quality Programs participant use file were eligible. Patients with severe head injury (head Abbreviated Injury Scale score, ≥3), prehospital cardiac arrest, and interhospital transfers were excluded. Logistic regression models were used to assess the effects of trauma center hospital teaching status on the adjusted odds of 3-hour, 6-hour, and 24-hour mortality. RESULTS: A total of 1,849 patients received MT (81% male; median Injury Severity Score, 26 [18-35]), 72% were admitted to level I trauma centers, and 28% were admitted to level II centers. Overall hospital mortality was 41%; 17% of patients died in 3 hours, 25% in 6 hours, and 33% in 24 hours. Teaching hospitals were associated with decreased 3-hour (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.27-0.75), 6-hour (OR, 0.37; 95% CI, 0.24-0.56), 24-hour (OR, 0.50; 95% CI, 0.34-0.75), and overall mortality (OR, 0.66; 95% CI, 0.44-0.98), compared with nonteaching hospitals, controlling for sex, age, heart rate, injury severity, injury mechanism, and trauma center verification level. CONCLUSION: Severely injured patients requiring MT experience significantly lower mortality at teaching hospitals compared with nonteaching hospitals, independently of trauma center verification level. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Nationwide outcomes of newborns with rectosigmoid versus long-segment Hirschsprung disease.

PURPOSE: Hirschsprung Disease (HD) is a common congenital intestinal disorder. While aganglionosis most commonly affects the rectosigmoid colon (rectosigmoid HD), outcomes for patients in which aganglionosis extends to more proximal segments (long-segment HD) remain understudied. This study sought to compare postoperative outcomes among newborns with rectosigmoid and long-segment HD. METHODS: The Nationwide Readmission Database was queried from 2016 to 2018 for newborns with HD. Newborns were stratified into those with rectosigmoid or long-segment HD. Those who received no rectal biopsy or pull-through procedure during their newborn hospitalization were excluded. A propensity score-matched analysis (PSMA) of newborns with either type of HD was constructed utilizing 17 covariates including demographics, comorbidities, and congenital-perinatal conditions. RESULTS: There were 1280 newborns identified with HD (82% rectosigmoid HD, 18% long-segment HD). Patients with rectosigmoid HD had higher rates of laparoscopic resections (35% vs. 12%) and less frequently received a concomitant ostomy (14% vs. 84%), both p < 0.001. Patients with long-segment HD were more likely to have a delayed diagnosis (12% vs. 5%) and require multiple bowel operations (19% vs. 4%), both p < 0.001. They experienced higher rates of complications, including small bowel obstructions (10% vs. 1%), infections (45% vs. 20%), and Hirschsprung-associated enterocolitis (11% vs. 5%), all p < 0.001. After PSMA, newborns with long-segment HD were found to have a longer length of stay and higher hospitalization costs. CONCLUSION: Newborns with long-segment HD experience significant delays in diagnosis, surgery, and complications compared to those with rectosigmoid HD. This information should be utilized to improve healthcare delivery for this patient population. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: III.

Operative versus percutaneous drainage with fibrinolysis for complicated pediatric pleural effusions: A nationwide analysis.

PURPOSE: Management of complicated pleural effusions and empyema using tube thoracostomy with intrapleural fibrinolysis versus surgical drainage has been debated for decades. However, there remains considerable variation in management with these approaches in the pediatric population. This study aims to compare the nationwide outcomes of pediatric patients with complicated pleural effusions. METHODS: Patients <18 years old with a diagnosis of pleural effusion or empyema associated with pneumonia were identified from the Nationwide Readmissions Database (2016-2018). Demographics, hospital characteristics, and complications were compared among patients undergoing isolated percutaneous drainage (PD), percutaneous drainage with intrapleural fibrinolysis (PDF), or operative drainage (OD) using standard statistical tests. RESULTS: 5424 patients (age 4 [IQR 1-11] years) were identified with a pleural effusion or empyema who underwent percutaneous or surgical intervention. PD (22%) and OD (24%) were utilized more frequently than PDF (3%). Index complications, including bleeding and postprocedural air leak, were similar between groups. Those receiving PDF had lower index length of stay (LOS) and admission costs. Thirty-day and overall readmission rates were highest in patients receiving PD (15% and 24%) and OD (12% and 23%) versus PDF, all p < 0.001. Those receiving OD had fewer readmission complications including recurrent effusion or empyema, pneumonia, and bleeding. Overall readmission cost was highest in those receiving PD (p = 0.005). CONCLUSION: In this nationwide cohort, PDF was associated with lower index admission cost, shorter LOS and lower rates of readmissions compared to OD. This knowledge should be used to improve selection of these treatments in this patient population. TYPE OF STUDY: Retrospective Comparative LEVEL OF EVIDENCE: III.
