Career Trajectory After General Surgery Residency: Do Academic Program Graduates Pursue Academic Surgery?

OBJECTIVE: Determine the proportion of contemporary US academic general surgery residency program graduates who pursue academic careers and identify factors associated with pursuing academic careers. SUMMARY BACKGROUND DATA: Many academic residency programs aim to cultivate academic surgeons, yet the proportion of contemporary graduates who choose academic careers is unclear. The potential determinants that affect graduates' decisions to pursue academic careers remain underexplored. METHODS: We collected program and individual-level data on 2015 and 2018 graduates across 96 US academic general surgery residency programs using public resources. We defined those pursuing academic careers as faculty within US allopathic medical school-affiliated surgery departments who published two or more peer-reviewed publications as the first or senior author between 2020-2021. After variable selection using sample splitting LASSO regression, multivariable regression evaluated association with pursuing academic careers among all graduates, and graduates of top-20 residency programs. Secondary analysis using multivariable ordinal regression explored factors associated with high research productivity during early faculty years. RESULTS: Among 992 graduates, 166 (17%) were pursuing academic careers according to our definition. Graduating from a top-20 ranked residency program (OR[95%CI]: 2.34[1.40-3.88]), working with a longitudinal research mentor during residency (OR[95%CI]: 2.21[1.24-3.95]), holding an advanced degree (OR[95%CI]: 2.20[1.19-3.99]), and the number of peer-reviewed publications during residency as first or senior author (OR[95%CI]: 1.13[1.07-1.20]) were associated with pursuing an academic surgery career, while the number of peer-reviewed publications before residency was not (OR[95%CI]: 1.08[0.99-1.20]). Among top 20 program graduates, working with a longitudinal research mentor during residency (OR[95%CI]: 0.95[0.43-2.09]) was not associated with pursuing an academic surgery career. The number of peer-reviewed publications during residency as first or senior author was the only variable associated with higher productivity during early faculty years (OR[95%CI]: 1.12[1.07-1.18]). CONCLUSIONS: Our findings suggest programs that aim to graduate academic surgeons may benefit from ensuring trainees receive infrastructural support and demonstrate sustained commitment to research throughout residency. Our results should be interpreted cautiously as the impact of unmeasured confounders is unclear.

Management of Uncomplicated Appendicitis in Adults: A Nationwide Analysis From 2018 to 2019.

INTRODUCTION: Nonoperative management (NOM) of uncomplicated appendicitis (UA) has been increasingly utilized in recent years. The aim of this study was to describe nationwide trends of sociodemographic characteristics, outcomes, and costs of patients undergoing medical versus surgical management for UA. METHODS: The 2018-2019 National (Nationwide) Inpatient Sample was queried for adults (age ≥18 y) with UA; diagnosis, as well as laparoscopic and open appendectomy, were defined by the International Classification of Diseases, 10th Revision, Clinical Modification codes. We examined several characteristics, including cost of care and length of hospital stay. RESULTS: Among the 167,125 patients with UA, 137,644 (82.4%) underwent operative management and 29,481 (17.6%) underwent NOM. In bivariate analysis, we found that patients who had NOM were older (53 versus 43 y, P < 0.001) and more likely to have Medicare (33.6% versus 16.1%, P < 0.001), with higher prevalence of comorbidities such as diabetes (7.8% versus 5.5%, P < 0.001). The majority of NOM patients were treated at urban teaching hospitals (74.5% versus 66.3%, P < 0.001). They had longer LOS's (5.4 versus 2.3 d, P < 0.001) with higher inpatient costs ($15,584 versus $11,559, P < 0.001) than those who had an appendectomy. Through logistic regression we found that older patients had up to 4.03-times greater odds of undergoing NOM (95% CI: 3.22-5.05, P < 0.001). CONCLUSIONS: NOM of UA is more commonly utilized in patients with comorbidities, older age, and those treated in teaching hospitals. This may, however, come at the price of longer length of stay and higher costs. Further guidelines need to be developed to clearly delineate which patients could benefit from NOM.

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters.

INTRODUCTION: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs). METHODS: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes. Within this sample, we analyzed characteristics and outcomes of patients with firearm-related injuries. The primary outcome was mortality; secondary outcomes were ED charges and length of stay. RESULTS: Among the 25.2 million substance use disorder (SUD) patients in our analysis, 35,306 (0.14%) had a firearm-related diagnosis. Compared to other SUD patients, firearm-SUD patients were younger (33.3 versus 44.7 years, P < 0.001), primarily male (88.6% versus 54.2%, P < 0.001), of lower-income status (0-25th percentile income: 56.4% versus 40.5%, P < 0.001), and more likely to be insured by Medicaid or self-pay (71.6% versus 53.2%, P < 0.001). Firearm-SUD patients had higher mortality (1.4% versus 0.4%, P < 0.001), longer lengths of stay (6.5 versus 4.9 days, P < 0.001), and higher ED charges ($9269 versus $5,164, P < 0.001). Firearm-SUD patients had a 60.3% rate of psychiatric diagnoses. Firearm-SUD patients had 5.5 times greater odds of mortality in adjusted analyses (adjusted odds ratio: 5.5, P < 0.001). CONCLUSIONS: Opioid-substance abuse patients with firearm injuries have higher mortality rates and costs among these groups, with limited discharge to postacute care resources. All these factors together point to the urgent need for improved screening and treatment for this vulnerable group of patients.

Explainable Machine Learning to Bring Database to the Bedside: Development and Validation of the TROUT (Trauma fRailty OUTcomes) Index, a Point-of-Care Tool to Prognosticate Outcomes After Traumatic Injury Based on Frailty.

OBJECTIVE: Exemplify an explainable machine learning framework to bring database to the bedside; develop and validate a point-of-care frailty assessment tool to prognosticate outcomes after injury. BACKGROUND: A geriatric trauma frailty index that captures only baseline conditions, is readily-implementable, and validated nationwide remains underexplored. We hypothesized Trauma fRailty OUTcomes (TROUT) Index could prognosticate major adverse outcomes with minimal implementation barriers. METHODS: We developed TROUT index according to Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis guidelines. Using nationwide US admission encounters of patients aged ≥65 years (2016-2017; 10% development, 90% validation cohorts), unsupervised and supervised machine learning algorithms identified baseline conditions that contribute most to adverse outcomes. These conditions were aggregated into TROUT Index scores (0-100) that delineate 3 frailty risk strata. After associative [between frailty risk strata and outcomes, adjusted for age, sex, and injury severity (as effect modifier)] and calibration analysis, we designed a mobile application to facilitate point-of-care implementation. RESULTS: Our study population comprised 1.6 million survey-weighted admission encounters. Fourteen baseline conditions and 1 mechanism of injury constituted the TROUT Index. Among the validation cohort, increasing frailty risk (low=reference group, moderate, high) was associated with stepwise increased adjusted odds of mortality {odds ratio [OR] [95% confidence interval (CI)]: 2.6 [2.4-2.8], 4.3 [4.0-4.7]}, prolonged hospitalization [OR (95% CI)]: 1.4 (1.4-1.5), 1.8 (1.8-1.9)], disposition to a facility [OR (95% CI): 1.49 (1.4-1.5), 1.8 (1.7-1.8)], and mechanical ventilation [OR (95% CI): 2.3 (1.9-2.7), 3.6 (3.0-4.5)]. Calibration analysis found positive correlations between higher TROUT Index scores and all adverse outcomes. We built a mobile application ("TROUT Index") and shared code publicly. CONCLUSION: The TROUT Index is an interpretable, point-of-care tool to quantify and integrate frailty within clinical decision-making among injured patients. The TROUT Index is not a stand-alone tool to predict outcomes after injury; our tool should be considered in conjunction with injury pattern, clinical management, and within institution-specific workflows. A practical mobile application and publicly available code can facilitate future implementation and external validation studies.

TraumaICDBERT, A Natural Language Processing Algorithm to Extract Injury ICD-10 Diagnosis Code from Free Text.

OBJECTIVE: To develop and validate TraumaICDBERT, a natural language processing algorithm to predict injury ICD-10 diagnosis codes from trauma tertiary survey notes. SUMMARY BACKGROUND DATA: The adoption of ICD-10 diagnosis codes in clinical settings for injury prediction is hindered by the lack of real-time availability. Existing natural language processing algorithms have limitations in accurately predicting injury ICD-10 diagnosis codes. METHODS: Trauma tertiary survey notes from hospital encounters of adults between January 2016 and June 2021 were used to develop and validate TraumaICDBERT, an algorithm based on BioLinkBERT. The performance of TraumaICDBERT was compared to Amazon Web Services Comprehend Medical, an existing natural language processing tool. RESULTS: A dataset of 3,478 tertiary survey notes with 15,762 4-character injury ICD-10 diagnosis codes was analyzed. TraumaICDBERT outperformed Amazon Web Services Comprehend Medical across all evaluated metrics. On average, each tertiary survey note was associated with 3.8 (standard deviation: 2.9) trauma registrar-extracted 4-character injury ICD-10 diagnosis codes. CONCLUSIONS: TraumaICDBERT demonstrates promising initial performance in predicting injury ICD-10 diagnosis codes from trauma tertiary survey notes, potentially facilitating the adoption of downstream prediction tools in clinical settings.

Racial/ethnic differences in acute and longer-term posttraumatic symptoms following traumatic injury or illness.

BACKGROUND: Racial/ethnic differences in mental health outcomes after a traumatic event have been reported. Less is known about factors that explain these differences. We examined whether pre-, peri-, and post-trauma risk factors explained racial/ethnic differences in acute and longer-term posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in patients hospitalized following traumatic injury or illness. METHODS: PTSD, depression, and anxiety symptoms were assessed during hospitalization and 2 and 6 months later among 1310 adult patients (6.95% Asian, 14.96% Latinx, 23.66% Black, 4.58% multiracial, and 49.85% White). Individual growth curve models examined racial/ethnic differences in PTSD, depression, and anxiety symptoms at each time point and in their rate of change over time, and whether pre-, peri-, and post-trauma risk factors explained these differences. RESULTS: Latinx, Black, and multiracial patients had higher acute PTSD symptoms than White patients, which remained higher 2 and 6 months post-hospitalization for Black and multiracial patients. PTSD symptoms were also found to improve faster among Latinx than White patients. Risk factors accounted for most racial/ethnic differences, although Latinx patients showed lower 6-month PTSD symptoms and Black patients lower acute and 2-month depression and anxiety symptoms after accounting for risk factors. Everyday discrimination, financial stress, past mental health problems, and social constraints were related to these differences. CONCLUSION: Racial/ethnic differences in risk factors explained most differences in acute and longer-term PTSD, depression, and anxiety symptoms. Understanding how these risk factors relate to posttraumatic symptoms could help reduce disparities by facilitating early identification of patients at risk for mental health problems.

A National Evaluation of Emergency General Surgery Outcomes Among Hospitalized Cardiac Patients.

INTRODUCTION: Emergency general surgery among cardiac surgery patients is increasingly common and consequential. We sought to characterize the true burden of emergency general surgery among hospitalized complex cardiac patients. METHODS: We performed a retrospective analysis of the 2016-2017 National Inpatient Sample. We included adult patients with a primary diagnosis of complex cardiac disease. We then compared patients who underwent emergency general surgery (GS-OR) with those who did not (non-GS-OR). The primary outcome was mortality; secondary outcomes included length of stay and hospitalization costs. RESULTS: We identified 10.2 million patients with a primary diagnosis of complex cardiac disease, of which 148,309 (1.4%) underwent GS-OR. Mortality rates were significantly higher in the GS-OR group (11.0% versus 5.0%, P < 0.001). Among all cardiac patients, GS-OR was associated with 2.2 times increased odds of death (aOR: 2.2, P < 0.001). GS-OR patients also had longer length of stays (14.1 versus 5.8 d, P < 0.001). Among all cardiac patients, GS-OR was associated with an 8.1-day longer length of stay (P < 0.001). GS-OR patients were less often routinely discharged home (31.7% versus 45.3%, P < 0.001) and incurred higher inpatient costs ($46,136 versus $16,303, P < 0.001). Among all cardiac patients, GS-OR patients incurred $30,102 higher hospitalization costs (P < 0.001). CONCLUSIONS: Emergency general surgery among cardiac surgery patients is associated with a greater than two-fold increase in mortality, longer length of stays, higher rates of nonroutine discharge, and higher hospitalization costs. Emergency general surgery complications account for 4.0% of total inpatient costs of cardiac surgery patients and merit further study.

Developing an Inpatient Relationship Centered Communication Curriculum (I-RCCC) rounding framework for surgical teams.

BACKGROUND: Morning rounds by an acute care surgery (ACS) service at a level one trauma center are uniquely demanding, given the fast pace, high acuity, and increased patient volume. These demands notwithstanding, communication remains integral to the success of surgical teams. Yet there are limited published curricula that address trauma inpatient communication needs. Observations at our institution confirmed that the surgical team lacked a shared mental model for communication. We hypothesized that creating a relationship-centered rounding conceptual framework model would enhance the provider-patient experience. STUDY DESIGN: A mixed-methods approach was used for this study. A multi-pronged needs assessment was conducted. Provider communion items for Press Ganey and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys were used to measure patients' expressed needs. Faculty with experience in relationship-centered communication observed morning rounds and documented demonstrated behaviors. A five-hour workshop was designed based on the identified needs. A pre-and post-course Assessment and course evaluation were conducted. Provider-related patient satisfaction items were measured six months before the course and six months after the workshop. RESULTS: Needs assessment revealed a lack of a shared communication framework and a lack of leadership skills for senior trauma residents. Barriers included: time constraints, patient load, and interruptions during rounds. The curriculum was very well received. The self-reflected behaviors that demonstrated the most dramatic change between the pre and post-workshop surveys were: I listened without interrupting; I spoke clearly and at a moderate pace; I repeated key points; and I checked that the patient understood. All these changed from being performed by 50% of respondents "about half of the time" to 100% of them "always". Press Ganey top box likelihood to recommend (LTR) and provider-related top box items showed a trend towards improvement after implementing the training with a percentage difference of up to 20%. CONCLUSION: The Inpatient Relationship Centered Communication Curriculum (I-RCCC) targeting senior residents and Nurse Practitioners (NP) was feasible, practical, and well-received by participants. There was a trend of an increase in LTRs and provider-specific patient satisfaction items. This curriculum will be refined based on the study results and potentially scalable to other surgical specialties.

Financial Burden of Traumatic Injury Amongst the Privately Insured.

OBJECTIVE: We sought to evaluate the overall financial burden associated with traumatic injury amongst patients with private insurance and assess the effect of high deductible plans on out-of-pocket costs (OOPCs). SUMMARY OF BACKGROUND DATA: Traumatic injury can be a source of unexpected financial burden for households. However, the effect of increasing participation in higher cost-sharing private health insurance plans remains unknown. METHODS: We conducted a retrospective cohort observational study, using the Clinformatics Data Mart Database, a nationwide single-payer administrative claims database to identify US adults who required emergency department services or hospital admission for single traumatic injury from 2008 to 2018. A 2-part model using a logistic regression and a generalized linear model with gamma distribution and log link was used to evaluate 12-month OOPCs after traumatic injury. Multivariable logistic regression was used to evaluate the likelihood of catastrophic health expenditure (CHE) after injury. RESULTS: Of 426,945 included patients, 53% were male, 71% were white, and median age was 42 years. Patients faced monthly OOPC of $660 at the time of their injury. High deductible plan enrollment was associated with an increase of $1703 in 12-month OOPC after trauma, compared to those covered by traditional health plans. In addition to high deductible health plan enrollment, worsening injury severity and longer hospital stays were also associated with increased 12-month OOPC after trauma. Non-white minorities paid less 12-month OOPC after trauma compared to non-Hispanic white patients, but also used fewer services. Overall, the incidence of CHE was 5%; however high-deductible health plan enrollees faced a 13% chance of CHE. CONCLUSIONS: Privately insured trauma patients face substantial OOPCs at the time of their injuries. High-deductible health plans are associated with increased financial vulnerability after trauma.

Professionalism of Admitting and Consulting Services and Trauma Patient Outcomes.

OBJECTIVE: To determine whether trauma patients managed by an admitting or consulting service with a high proportion of physicians exhibiting patterns of unprofessional behaviors are at greater risk of complications or death. SUMMARY BACKGROUND DATA: Trauma care requires high-functioning interdisciplinary teams where professionalism, particularly modeling respect and communicating effectively, is essential. METHODS: This retrospective cohort study used data from 9 level I trauma centers that participated in a national trauma registry linked with data from a national database of unsolicited patient complaints. The cohort included trauma patients admitted January 1, 2012 through December 31, 2017. The exposure of interest was care by 1 or more high-risk services, defined as teams with a greater proportion of physicians with high numbers of patient complaints. The study outcome was death or complications within 30 days. RESULTS: Among the 71,046 patients in the cohort, 9553 (13.4%) experienced the primary outcome of complications or death, including 1875 of 16,107 patients (11.6%) with 0 high-risk services, 3788 of 28,085 patients (13.5%) with 1 high-risk service, and 3890 of 26,854 patients (14.5%) with 2+ highrisk services (P < 0.001). In logistic regression models adjusting for relevant patient, injury, and site characteristics, patients who received care from 1 or more high-risk services were at 24.1% (95% confidence interval 17.2% to 31.3%; P < 0.001) greater risk of experiencing the primary study outcome. CONCLUSIONS: Trauma patients who received care from at least 1 service with a high proportion of physicians modeling unprofessional behavior were at an increased risk of death or complications.

'I knew I'd be taken care of': Exploring patient experiences in the Emergency Department.

AIMS: To explore adult Emergency Department patient experiences to inform the development of a new Emergency Department patient-reported experience measure. DESIGN: Descriptive, exploratory qualitative study using semi-structured individual interviews with adult Emergency Department patients. METHODOLOGY: Participants were recruited across two Emergency Departments in Southeast Queensland, Australia during September and October 2020. Purposive sampling based on maximum variation was used. Participants were recruited during their Emergency Department presentation and interviewed in 2-weeks via telephone. Inductive thematic analysis followed the approach proposed by Braun and Clarke (2012). RESULTS: Thirty participants were interviewed, and four themes were inductively identified: Caring relationships between patients and Emergency Department care providers; Being in the Emergency Department environment; Variations in waiting for care; and Having a companion in the Emergency Department. Caring relationships between patients and Emergency Department care providers included being treated like a person and being cared for, being informed about and included in care, and feeling confident in care providers. Being in the Emergency Department environment included being around other patients, feeling comfortable and having privacy. Variations in waiting for care included expecting a longer wait, waiting throughout the Emergency Department journey and receiving timely care. Having a companion in the Emergency Department included not feeling alone, and observing care providers engage with companions. CONCLUSION: Patient experiences in the Emergency Department are multifaceted, and themes are not mutually exclusive. These findings demonstrate consistency with the core experiential themes identified in the international literature. IMPACT: Strategies to improve patient engagement in shared decision-making, and communication between patients and care providers about wait times will be critical to optimizing Emergency Department patient experiences, and person-centred practice. These findings holistically conceptualize patient experiences in the Emergency Department which is the first step to developing a new Emergency Department patient-reported experience measure.

Outcomes of the First Virtual General Surgery Certifying Exam of the American Board of Surgery.

OBJECTIVE: To Study the Outcomes of the First Virtual General Surgery Certifying Exam of the American Board of Surgery. SUMMARY OF BACKGROUND DATA: The ABS General Surgery CE is normally an in-person oral examination. Due to the COVID-19 outbreak, the ABS was required to reschedule these. After 2 small pilots, the CE's October administration represented the first large-scale remote virtual exam. The purpose of this report is to compare the outcomes of this virtual and the previous in-person CEs. METHODS: CE candidates were asked to provide feedback on their experience via a survey. The passing rate was compared to the 1025 candidates who took the 2019-2020 in-person CEs. RESULTS: Of the 308 candidates who registered for the virtual CE, 306 completed the exam (99.4%) and 188 completed the survey (61.4%). The majority had a very positive experience. They rated the virtual CE as very good/excellent in security (90%), ease of exam platform (77%), audio quality (71%), video quality (69%), and overall satisfaction (86%). Notably, when asked their preference, 78% preferred the virtual exam. There were no differences in the passing rates between the virtual or in-person exams. CONCLUSIONS: The first virtual CE by the ABS was completed using available internet technology. There was high satisfaction, with the majority preferring the virtual platform. Compared to past in-person CEs, there was no difference in outcomes as measured by passing rates. These data suggest that expansion of the virtual CE may be desirable.

COVID-19 Impact on Surgical Resident Education and Coping.

BACKGROUND: Healthcare systems and surgical residency training programs have been significantly affected by the novel coronavirus disease 2019 (COVID-19) pandemic. A shelter-in-place and social distancing mandate went into effect in our county on March 16, 2020, considerably altering clinical and educational operations. Along with the suspension of elective procedures, resident academic curricula transitioned to an entirely virtual platform. We aimed to evaluate the impact of these modifications on surgical training and resident concerns about COVID-19. MATERIALS AND METHODS: We surveyed residents and fellows from all eight surgical specialties at our institution regarding their COVID-19 experiences from March to May 2020. Residents completed the survey via a secure Qualtrics link. A total of 38 questions addressed demographic information and perspectives regarding the impact of the COVID-19 pandemic on surgical training, education, and general coping during the pandemic. RESULTS: Of 256 eligible participants across surgical specialties, 146 completed the survey (57.0%). Junior residents comprised 43.6% (n = 61), compared to seniors 37.1% (n = 52) and fellows 19.3% (n = 27). Most participants, 97.9% (n = 138), anticipated being able to complete their academic year on time, and 75.2% (n = 100) perceived virtual learning to be the same as or better than in-person didactic sessions. Participants were most concerned about their ability to have sufficient knowledge and skills to care for patients with COVID-19, and the possibility of exposure to COVID-19. CONCLUSIONS: Although COVID-19 impacted residents' overall teaching and clinical volume, residency programs may identify novel virtual opportunities to meet their educational and research milestones during these challenging times.

Prospectively Assigned AAST Grade versus Modified Hinchey Class and Acute Diverticulitis Outcomes.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) recently developed a classification system to standardize outcomes analyses for several emergency general surgery conditions. To highlight this system's full potential, we conducted a study integrating prospective AAST grade assignment within the electronic medical record. METHODS: Our institution integrated AAST grade assignment into our clinical workflow in July 2018. Patients with acute diverticulitis were prospectively assigned AAST grades and modified Hinchey classes at the time of surgical consultation. Support vector machine-a machine learning algorithm attuned for small sample sizes-was used to compare the associations between the two classification systems and decision to operate and incidence of complications. RESULTS: 67 patients were included (median age of 62 y, 40% male) for analysis. The decision for operative management, hospital length of stay, intensive care unit admission, and intensive care unit length of stay were associated with both increasing AAST grade and increasing modified Hinchey class (all P < 0.001). AAST grade additionally showed a correlation with complication severity (P = 0.02). Compared with modified Hinchey class, AAST grade better predicted decision to operate (88.2% versus 82.4%). CONCLUSIONS: This study showed the feasibility of electronic medical record integration to support the full potential of AAST classification system's utility as a clinical decision-making tool. Prospectively assigned AAST grade may be an accurate and pragmatic method to find associations with outcomes, yet validation requires further study.

Regionalization Patterns for Children with Serious Trauma in California (2005-2015): A Retrospective Cohort Study.

OBJECTIVE: Trauma centers provide coordinated specialty care and have been demonstrated to save lives. Many states do not have a comprehensive statewide trauma system. Variable geography, resources, and population distributions present significant challenges to establishing an effective uniform system for pediatric trauma care. We aimed to identify patterns of primary (field) triage and transfer of serious pediatric trauma throughout California. We hypothesized that pediatric primary triage to trauma center care would be positively associated with younger age, increased injury severity, and local emergency medical service (EMS) regions with increased resources. We hypothesized that pediatric trauma transfer would be associated with younger age, increased injury severity, and rural regions with decreased resources. Methods: We conducted a retrospective cohort study of the California Office of Statewide Health Planning and Development emergency department and inpatient discharge data (2005-2015). All patients with serious injury, defined as Injury Severity Score (ISS) >9 were included. Demographic, injury, hospital, and regional characteristics such as distances between patient residence and destination hospitals were tabulated. Univariate and multinomial logit analyses were conducted to analyze individual, hospital, and regional characteristics associated with the outcomes of location of primary triage and transfer. Estimates were converted into predicted probabilities for ease of data interpretation. Results: Primary triage to was to either a pediatric trauma center (37.8%), adult level I/II trauma center (35.0%), adult level III/IV trauma center (1.9%), pediatric non-trauma hospital (3.4%), or an adult non-trauma hospital (21.9%).Younger age, private non-HMO insurance, motor vehicle mechanism, and rural areas were the major factors influencing primary triage to any trauma hospital. Younger age, private non-HMO insurance, higher ISS, fall mechanism, <200 bed hospital, and rural areas were the major factors influencing transfer from a non-trauma hospital to any trauma center. Conclusions: We demonstrate statewide primary triage and transfer patterns for pediatric trauma in a large and varied state. Specifically we identified previously unrecognized individual, hospital, and EMS system associations with pediatric trauma regionalization. Knowledge of these de facto trauma care access patterns has policy and process implications that could improve care for all injured children in need.

Situating Artificial Intelligence in Surgery: A Focus on Disease Severity.

OBJECTIVES: Artificial intelligence (AI) has numerous applications in surgical quality assurance. We assessed AI accuracy in evaluating the critical view of safety (CVS) and intraoperative events during laparoscopic cholecystectomy. We hypothesized that AI accuracy and intraoperative events are associated with disease severity. METHODS: One thousand fifty-one laparoscopic cholecystectomy videos were annotated by AI for disease severity (Parkland Scale), CVS achievement (Strasberg Criteria), and intraoperative events. Surgeons performed focused video review on procedures with ≥1 intraoperative events (n = 335). AI versus surgeon annotation of CVS components and intraoperative events were compared. For all cases (n = 1051), intraoperative-event association with CVS achievement and severity was examined using ordinal logistic regression. RESULTS: Using AI annotation, surgeons reviewed 50 videos/hr. CVS was achieved in ≤10% of cases. Hepatocystic triangle and cystic plate visualization was achieved more often in low-severity cases (P < 0.03). AI-surgeon agreement for all CVS components exceeded 75%, with higher agreement in high-severity cases (P < 0.03). Surgeons agreed with 99% of AI-annotated intraoperative events. AI-annotated intraoperative events were associated with both disease severity and number of CVS components not achieved. Intraoperative events occurred more frequently in high-severity versus low-severity cases (0.98 vs 0.40 events/case, P < 0.001). CONCLUSIONS: AI annotation allows for efficient video review and is a promising quality assurance tool. Disease severity may limit its use and surgeon oversight is still required, especially in complex cases. Continued refinement may improve AI applicability and allow for automated assessment.

Traumatic Injuries Due to Interpersonal and Domestic Violence in the United States.

BACKGROUND: Domestic and intimate partner violence (DV) are under-reported causes of injury. We describe the health care utilization of DV patients, hypothesizing they are at increased risk of mortality. METHODS: We queried the 2014 Nationwide Emergency Department Sample for adult patients (18 y and older) with a primary diagnosis of trauma. DV was abstracted using International Statistical Classification of Diseases, ninth Revision codes for partner or spouse intimate violence, abuse, or neglect. The primary outcome was mortality; secondary outcomes included admission rates and charges. RESULTS: Among 14 million trauma patients, 654,356 (5.0%) had a diagnosis of DV. Compared with other trauma patients, DV patients were younger (34.6 versus 46.8 y, P < 0.001), more often male (69.5% versus 50.1%, P < 0.001), and more likely to be uninsured (31.5% versus 15.6%, P < 0.001). 9154 (1.4%) were injured because of intimate partner violence, of which 90.2% were female. Drug and alcohol abuse (22.2%), anxiety (1.8%), and depression (1.3%) were high among all DV trauma patients. DV emergency department charges were higher ($4462 versus $2,871, P < 0.001). In adjusted analyses, DV trauma patients had 2.1 higher odds of mortality (aOR: 2.31, P < 0.001). DV trauma patients were also associated with a $1516 increase in emergency department charges compared with non-DV trauma patients (95% CI: $1489-$1,542, P < 0.001). CONCLUSIONS: Injuries related to all types of DV are emerging as a public health crisis among both genders. To mitigate under-reporting, it is important to identify at-risk patients and provide them with appropriate resources.

Mortality After General Surgery Among Hospitalized Patients With Hematologic Malignancy.

BACKGROUND: Hospitalized patients with hematologic malignancies (HMs) may require abdominal operations for complications of malignancy, treatment sequelae, or unrelated abdominal pathology. We determined predictors of mortality after emergency general surgery for patients with HM using national-level data. MATERIALS AND METHODS: We analyzed the 2010-2014 National Inpatient Sample for International Classification of Disease, Ninth Revision, Clinical Modification codes for HM and abdominal operations, comparing adult patient encounters with abdominal operations with HM to those without HM. Multivariate logistic regression was performed to identify predictors of mortality. RESULTS: Of the 7.9 million adult inpatient encounters where abdominal surgery was performed, 82,187 (1%) had concomitant diagnoses of HM. Mortality among patient encounters with HM was significantly higher than without HM (9.0% versus 2.0%; P < 0.0001). Patient encounters with HM and surgery and a diagnosis of acute abdominal pain had mortality rates as high as 41%. The median standardized risk ratio for death after the top 25 general surgery procedures was 2.9 (interquartile range: 2.2-3.8) among patients with HM. In adjusted analyses, odds of mortality among patients with HM undergoing surgery were increased by concomitant acute abdominal pain diagnosis (odds ratio [OR] = 2.6; P < 0.0001), coagulopathy (OR = 2.0; P < 0.0001), aplastic anemia (OR = 1.7; P < 0.0001), peripheral vascular disease (OR = 1.4; P = 0.001), and weight loss (OR = 1.3; P < 0.0001). CONCLUSIONS: Although uncommon, surgery on patients with HM is associated with mortality rates nearly five times higher than the general surgical population. Patients with HM requiring surgical intervention may be at particularly high odds of death and postoperative complications.

Hospital Readmission After Climbing-Related Injury in the United States.

INTRODUCTION: Rock climbing and mountaineering may result in injury requiring hospital admission. Readmission frequency after climbing-related injury is unknown. The aim of this study was to assess readmission frequency, morbidity, and mortality after admission for climbing-related injury. METHODS: We performed a retrospective analysis of the 2012 to 2014 national readmission database, a nationally representative sample of all hospitalized patients. Rock climbing, mountain climbing, and wall climbing injuries were identified using International Classification of Diseases-Ninth Revision-Clinical Modification codes (E004.0). Outcomes evaluated included readmission frequency, morbidity, mortality, inpatient admission, and costs. Adjusted analyses accounting for survey methodology were performed. Data are presented as mean±SD. RESULTS: A weighted-estimate 1324 inpatient admissions were associated with a climbing-related injury. Most patients were aged 18 to 44 y (64%), and 68% (n=896) were male. Isolated extremity injures were more common than other injuries (49%, n=645). Sixty-five percent (n=856) underwent a major operative procedure. Less than 1% of all climbing-related visits resulted in death. Within 6 mo of the index hospitalization, 2% (n=23) of the patients had at least 1 readmission, with a time to readmission of 9.9±6.6 (95% CI 4.5-15.4) d. Only female sex was associated with increased odds of readmission (odds ratio=5.5; 95% CI 1.5-20.1; P=0.01). CONCLUSIONS: There is a very low frequency of readmissions after being admitted to the hospital for climbing-related injury. A considerable opportunity to describe the long-term burden of climbing-related injury exists, and further research should be done to assess injury burden treated in the outpatient setting.

Implementation Challenges Using a Novel Method for Collecting Patient-Reported Outcomes After Injury.

BACKGROUND: Monitoring longitudinal patient-reported outcomes after injury is important for comprehensive trauma care. Current methodologies are resource-intensive and struggle to engage patients. MATERIALS AND METHODS: Patients ≥18 y old admitted to the trauma service were prospectively enrolled. The following inclusion criteria were used: emergency operation, ICU length of stay ≥2 midnights, or hospital length of stay ≥4 d. Validated and customized questionnaires were administered using a novel internet-based survey platform. Three-month follow-up surveys were administered. Contextual field notes regarding barriers to enrollment/completion of surveys and challenges faced by participants were recorded. RESULTS: Forty-seven patients were eligible; 26 of 47 (55%) enrolled and 19 of 26 (73%) completed initial surveys. The final sample included 14 (74%) men and 5 (26%) women. Primary barriers to enrollment included technological constraints and declined participation. Contextual field notes revealed three major issues: competing hospital tasks, problems with technology, and poor engagement. The average survey completion time was 43 ± 27 min-21% found this too long. Seventy-four percent reported the system "easy to use" and 95% reported they would "very likely" or "definitely" respond to future surveys. However, 10 of 26 (38%) patients completed 3-mo follow-up. CONCLUSIONS: Despite a well-rated internet-based survey platform, study participation remained challenging. Lack of email access and technological issues decreased enrollment and the busy hospitalization posed barriers to completion. Despite a thoughtful operational design and implementation plan, the trauma population presented a challenging group to engage. Next steps will focus on optimizing engagement, broadening access to survey reminders, and enhancing integration into clinical workflows.
