Growing the next generation of trauma surgeon-scientists: Reflections on 20 years of research investment.

INTRODUCTION: The Eastern Association for the Surgery of Trauma mission includes fostering research and providing career development opportunities. Eastern Association for the Surgery of Trauma has awarded for 20 years a research scholarship to a promising young investigator. The research mentorship efforts were expanded 5 years ago with the INVEST-C Hack-a-thon. INVEST-C provides an intensive, short-term engagement to propel junior faculty toward establishing research independence. This study investigates the impact of these programs on academic productivity. METHODS: Pubmed records, National Institutes of Health (NIH) Reporter data, and SCOPUS h-index were acquired for all scholarship (SCH) awardees from 2002 to 2021 (n = 20) and all INVEST-C (INV) participants (2017-2020, n = 19). Current type of practice, total number of funding awards, and timing of first award were ascertained. INVEST-C participants were also surveyed on an annual basis to track their progress. Medians (interquartile range [IQR]) are reported and compared (analysis of variance). RESULTS: Median publications (PUBs) of SCH awardees were 56 (IQR, 33-88), h-index was 16 (IQR, 12-21), and 25% of awardees have ≥1 NIH grant since their SCH. Among the last 10 awardees with a minimum of 2 years from SCH, 40% have received an NIH award compared with a mean NIH funding rate of 18.5% over the same period. For those remaining in academics (90% SCH), PUBs were higher for those >5 years (66 [IQR, 51-115]) versus <5 years from their SCH (33 [22-59]; p = 0.05), but there was no difference in h-index (16 [IQR, 14-25] vs. 15 [9-19], p = NS). Comparing the most recent 5 years of SCH to INV group, there was no difference in academic productivity as measured by total PUBs (SCH, 33 [IQR, 22-59] vs. INV, 34 [IQR, 18-44]; p = 0.7) or h-index (INV, 9 [IQR, 5-14]; p = 0.1). However, no attendee held research funding before INV, but 31.6% (6 of 19 attendees) have subsequently acquired ≥1 funding award (11 non-NIH, 1 NIH) in the short interval since participation. CONCLUSION: Investments in research activities have translated to significant extramural funding. Those in the last 5 years have been particularly fruitful with INV participants already achieving equal median academic productivity to SCH recipients.

Loss of Community-Dwelling Status Among Survivors of High-Acuity Emergency General Surgery Disease.

OBJECTIVES: To examine loss of community-dwelling status 9 months after hospitalization for high-acuity emergency general surgery (HA-EGS) disease among older Americans. DESIGN: Retrospective analysis of claims data. SETTING: US communities with Medicare beneficiaries. PARTICIPANTS: Medicare beneficiaries age 65 years or older hospitalized urgently/emergently between January 1, 2015, and March 31, 2015, with a principal diagnosis representing potential life or organ threat (necrotizing soft tissue infections, hernias with gangrene, ischemic enteritis, perforated viscus, toxic colitis or gastroenteritis, peritonitis, intra-abdominal hemorrhage) and an operation of interest on hospital days 1 or 2 (N = 3319). MEASUREMENTS: Demographic characteristics (age, race, and sex), comorbidities, principal diagnosis, complications, and index hospitalization disposition (died; discharged to skilled nursing facility [SNF], long-term acute care [LTAC], rehabilitation, hospice, home (with or without services), or acute care hospital; other) were measured. Survivors of index hospitalization were followed until December 31, 2015, on mortality and community-dwelling status (SNF/LTAC vs not). Descriptive statistics, Kaplan-Meier plots, and χ2 tests were used to describe and compare the cohort based on disposition. A multivariable logistic regression model, adjusted for age, sex, comorbidities, complications, and discharge disposition, determined independent predictors of loss of community-dwelling status at 9 months. RESULTS: A total of 2922 (88%) survived index hospitalization. Likelihood of discharge to home decreased with increasing age, baseline comorbidities, and in-hospital complications. Overall, 418 (14.3%) HA-EGS survivors died during the follow-up period. Among those alive at 9 months, 10.3% were no longer community dwelling. Initial discharge disposition to any location other than home and three or more surgical complications during index hospitalization were independent predictors of residing in a SNF/LTAC 9 months after surviving HA-EGS. CONCLUSION: Older Americans, known to prioritize living in the community, will experience substantial loss of independence due to HA-EGS. Long-term expectations after surviving HA-EGS must be framed from the perspective of the outcomes that older patients value the most. Further research is needed to examine the quality-of-life burden of EGS survivorship prospectively. J Am Geriatr Soc 67:2289-2297, 2019.

Gunshot Injuries to the Extremity: Is Immediate General Surgery Presence Needed?

Gunshot wounds (GSW) are becoming increasingly prevalent in urban settings. GSW to the trunk mandate full trauma activation and immediate surgeon response because of the high likelihood of operative intervention. Extremity GSW proximal to the knee/elbow also require full trauma activation based on American College of Surgeons Committee on trauma standards. However, whether isolated extremity GSW require frequent operative intervention is unclear. We evaluated GSW at our Level I trauma center from January 2012 to December 2016. Demographic data and injury patterns were abstracted from the trauma registry and charts. The number of GSW increased yearly but the age, gender, Injury Severity Score and injury pattern did not change (P = ns, not shown). There were 504 GSW that included an extremity and 194 (38%) involved multiple body regions. There were 310 GSW (62%) isolated to an extremity and 176 were proximal to the elbow/knee. If proximal GSW had an Emergency Department systolic blood pressure <90 mm Hg, 53 per cent underwent vascular repair, 12 per cent had soft tissue repair, and 29 per cent required no operation. If proximal GSW had an Emergency Department blood pressure >90 mm Hg, 57 per cent underwent orthopedic repair, 22 per cent required no surgery, and only 13 per cent required vascular repair (P < 0.01). In the absence of other criteria for full trauma activation such as shock, the need for the immediate presence of a general surgeon to perform emergency surgery for a GSW isolated to the extremity is low.

Organ donation as an outcome of traumatic cardiopulmonary arrest: A cost evaluation.

BACKGROUND: Survival after traumatic cardiopulmonary arrest (TCPA) is rare and requires significant resource expenditure. Organ donation as an outcome of TCPA resuscitation has not yet been included in a cost analysis. The aims of this study were to identify variables associated with survival and organ donation after TCPA, and to estimate the cost of achieving these outcomes. We hypothesized that the inclusion of organ donation as a potential outcome would make TCPA resuscitation more cost-effective. METHODS: Adult patients who required resuscitation for TCPA at a level I trauma center were retrospectively reviewed over 36 months. Data were obtained from medical records, hospital accounting records, and the local organ procurement agency. Outcomes included survival to discharge, neurologic function, and organ donor eligibility. An individual-level state-transition cost-effectiveness model was used to evaluate the cost of TCPA resuscitation with and without organ donation included as an outcome. Incremental cost-effectiveness ratio was calculated to determine additional cost per life saved when organ donation is included. RESULTS: Over the study period, 8,932 subjects were evaluated. Traumatic cardiopulmonary arrest occurred in 237 patients (3%). The mortality rate was 97%. Variables associated with survival included emergency department disposition to the operating room (p < 0.01) and reactive pupils (p < 0.001). Of seven survivors, four were discharged neurologically intact. Of the patients with TCPA, 5% were eligible for organ donation with a procurement rate of 2%. Organ donor eligibility was associated with arrest after arrival to the emergency department (p < 0.01) and transfusion of fresh frozen plasma (p = 0.01). The cost of TCPA resuscitation per survivor was $1.8 million; cost per survivor or life saved by donation was $538,000. The incremental cost-effectiveness ratio was $76,816 per additional life saved including donation as an outcome. CONCLUSION: The decision to pursue resuscitation should continue to be based on the presence of signs of life, especially pupil reactivity and duration of arrest. If the primary objective is survival, organ procurement will be maximized without conflict of interest. Early fresh frozen plasma transfusion may increase successful organ donation. The financial burden of TCPA resuscitation can be mitigated by expanding end points to include organ donation. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level III; cost analysis, level V.

Video-assisted thoracoscopy as an important tool for trauma surgeons: a systematic review.

PURPOSE: Trauma patients frequently have serious chest injuries. Retained hemothoraces and persistent pneumothoraces are among the most frequent complications of chest injuries which may lead to major, long-term morbidity and mortality if these complications are not recognized and treated appropriately. Video-assisted thoracoscopy (VATS) is a well-established technique in surgical practice. The usefulness of VATS for treatment of complications after chest trauma has been demonstrated by several authors. However, there is an ongoing debate about the optimal timing of VATS. METHODS: A computerized search was conducted which yielded 450 studies reporting on the use of VATS for thoracic trauma. Eighteen of these studies were deemed relevant for this review. The quality of these studies was assessed using a check-list and the PRISMA guidelines. Outcome parameters were successful evacuation of the retained hemothorax or treatment of other complications as well as reduction of empyema rate, length of hospital stay, and hospital costs. RESULTS: There was only one randomized trial and two prospective studies. Most studies report case series of institutional experiences. VATS was found to be very successful in evacuation of retained hemothoraces and seems to reduce the empyema rate subsequently. Furthermore, the length of hospital stay and costs can be drastically reduced with the early use of VATS. CONCLUSION: Early VATS is an effective treatment for retained hemothoraces or other complications of chest trauma. We propose a clinical pathway, in which VATS is used as an early intervention in order to prevent serious complications such as empyemas or trapped lung.

Acute appendicitis--not just for the young.

BACKGROUND: The incidence of appendicitis is highest in young patients, but the number of elderly patients with appendicitis appears to be increasing. The authors evaluated a statewide experience to assess the effect of age on resource utilization and outcomes for this common disease. METHODS: All discharges from Kentucky hospitals for appendicitis were identified. Patients from rehabilitation hospitals, those with inflammatory bowel disease, and those undergoing incidental appendectomy were excluded. RESULTS: Young (aged ≤ 29 years) and middle-aged (aged 30-64 years) patients each constituted 45% of all patients with appendicitis. Length of stay, hospital charges, and frequency of complicated appendicitis all increased with age. Although elderly patients (aged ≥ 80 years) underwent laparoscopic appendectomy as frequently (60%) as younger patients, they were more likely to undergo complicated open procedures. CONCLUSIONS: Older patients represent a substantial population of patients with appendicitis, with more complicated operative procedures, increased lengths of stay, and increased resource utilization.

Incremental increases in organ retrieval after protocol driven change in an organ procurement organization: a 15-year assessment.

The need for transplantable organs exceeds the available supply. Organ procurement organizations (OPOs) have undergone both voluntary and mandated changes to optimize available organs. The data from a single statewide OPO was reviewed from 1993 to 2008 and tracked with implementation of new protocols. During the study, 5548 organs were recovered with 4875 transplanted from 1441 donors (3.38 organs transplanted/donor (OTPD)). The conversion rate (CR) for consent rose from 42 to 72 per cent whereas the average age of donors increased from 33 to 45 years. After implementation of a family support liaison program, a higher performing hospital in the OPO realized an increase in CR from 57 to 97 per cent over 8 years. Implementation of an intensivist program improved OTPD. The number of standard criteria donors and extended criteria donors (ECD) increased. The increase in standard criteria donors yielded a large number of thoracic organs. ECD increased as did the organ discard rate from 8 to 16 per cent. Increases in organ retrieval were noted after incremental changes in OPO protocol. Family support and intensivist programs enhanced CR and OTPD. Increases in the number of ECD were noted with increasing age after the introduction of the intensivist program and an increase in transplant center use of these organs.
