Characteristics of ocular injuries associated with mortality in patients admitted with major trauma.

BACKGROUND: Few ocular trauma studies have addressed mortality outcomes. We sought to determine characteristics of mortality-related ocular trauma admissions and compared them with non-fatal injuries. METHODS: A retrospective study was conducted using de-identified data of patients admitted with major trauma from the National Trauma Data Bank (2008-2014). Patients with ocular injury were identified using ICD- 9CM codes. Demographics, intention and mechanism, types of ocular and head injuries, and injury severity were documented. Mortality was determined using post-admission disposition. Statistical analysis using student t-test, chi-square, and odds ratios (OR) calculations were performed with STATA-17 software. Significance was set at P < 0.05. RESULTS: Of 316,485 patients admitted with ocular trauma, 12,233 (3.86%) were mortality related. Expired patients were older than survivors: mean (SD) of 50.1(25.5) vs. 41.5(22.8) years. White (OR = 1.32; P < 0.001), ≥ 65years old (OR = 2.25; P < 0.001), and male (OR = 1.05; P = 0.029) patients were most likely to expire than their counterparts. Common mechanisms of injury in survivors were falls (25.3%), motor vehicle traffic-occupant, MVTO (21.8%) and struck by/against (18.1%) and for fatal injuries, falls (29.7%), MVTO (21.9%) and firearms (11.5%). Traumatic brain injury (TBI) was documented in 88.2% of mortality-related admissions. Very severe injury severity scores (ISS > 24) (OR = 19.19; P < 0.001) and severe Glasgow Coma Score (GCS < 8) (OR = 19.22; P < 0.001) were most associated with mortality than survival. Firearms were most associated with very severe ISS (OR = 3.73; P < 0.001), severe GCS (OR = 4.68; P < 0.001) and mortality (OR = 5.21; P < 0.001) than other mechanisms. Patients with cut/pierce injuries had the greatest odds of survival (OR = 13.48; P < 0.001). Optic nerve/visual pathways injuries (3.1%) had the highest association with very severe ISS (OR = 2.51; P < 0.001), severe GCS (OR = 3.64; P < 0.001) and mortality (OR = 2.58; P < 0.001) than other ocular injuries. Black patients with very severe ISS (OR = 32.14; P < 0.001) and severe GCS (OR = 31.89; P < 0.001) were more likely to expire than other race/ethnicities with similar injury severity. CONCLUSIONS: Mortality-related admissions were older, male, and mostly of White race than ocular trauma admissions of survivors. Firearms were the deadliest mechanism. TBI was commonly associated and patients with optic nerve/pathway injuries, very severe ISS and severe GCS had higher mortality rates. Characteristics and demographic variations identified in this study may be useful in developing focused measures aimed at preventing trauma-related deaths.

Characteristics and associations of ocular and non-ocular manifestations of shaken baby syndrome.

OBJECTIVES: Shaken baby syndrome (SBS), a subset of abusive head trauma, results from non-accidental, violent head shaking. Most survivors suffer permanent neurological sequelae. Accurate diagnosis is imperative and remains challenging. The purpose of this study is to describe ocular injuries and associated neurotrauma in suspected SBS. METHODS: We retrospectively surveyed the National Trauma Data Bank 2008-2014 for patients ≤ 3 years old admitted for suspected SBS. Statistical analysis was performed with SPSS software. Significance was set at p < 0.05. RESULTS: Three hundred forty-seven (13.9%) of 2495 patients who were ≤ 3 years old were admitted with abusive head trauma and ocular injuries which resulted from suspected SBS. Most were < 1 year old (87.9%) and male (54.2%). Common eye injuries were retinal hemorrhages (30.5%), eye/adnexa contusion (14.7%), and retinal edema (10.7%). Common neurotrauma were subdural (75.5%), subarachnoid (23.9%), and intracerebral hemorrhage (ICH) (10.4%). Mean (SD) Injury Severity Score was severe, 20.2 (8.2), and Glasgow Coma Score was moderate, 9.2 (12.8). The mortality rate was 16.7%. Retinal hemorrhages were not significantly associated with one type of neurotrauma over others. Ocular/adnexa contusion (OR 4.06; p < 0.001) and commotio retinae/Berlin's edema (OR 5.27; p < 0.001) had the greatest association with ICH than other neurotrauma. Optic neuropathy (OR 21.33; p < 0.001) and ICH (OR 3.34; p < 0.001) had the highest associated with mortality. CONCLUSIONS: Our study supports previous studies showing that retinal and subdural hemorrhages were the most common ocular injury and neurotrauma in SBS, respectively. However, we did not find a significant propensity for their concurrence. Commotio retinae/Berlin's edema was significantly associated with both intracerebral and subdural hemorrhages.

Delayed Graft Function in Kidney Retransplantation: United Network for Organ Sharing Data With Linked Primary and Retransplant.

INTRODUCTION: There are several articles exploring the risk factors for primary delayed graft function (DGF). However, current literature does not include many resources on the risk factors for DGF when it is a recipient's second kidney transplant or look at short-term graft and patient survival of DGF retransplants. METHODS: United Network for Organ Sharing data from January 2008 to June 2021 were analyzed. Pancreas transplants, multi-organ transplants, and lost to follow-up transplants were excluded. Second transplant patients with DGF were identified. Multivariate logistic regression models based on the primary and second transplant characteristics were created. Survival analysis was performed with Kaplan-Meier methodology and assessed with log-rank test. RESULTS: A total of 2964 second kidney transplants were identified. Rate of DGF in the second transplant was 28.4% (843/2964) and 49.2% of them had a prior DGF in their first transplant (P < 0.001). Multivariate analysis confirmed that occurrence of DGF (odds ratio [OR] 1.5, P < 0.001) and graft loss due to acute rejection (OR 1.2, P < 0.005) in the primary transplant were predictors of reappearing DGF in the second transplant. Dialysis at transplant was the greatest risk factor from the second transplant (OR 3.539, P < 0.001). There was a decreased graft survival after 12 mo (77% versus 49% with log t-test <0.001) in the second transplant. However, DGF was not significantly associated with patient survival. CONCLUSIONS: This study shows the interaction between primary and second transplant in developing DGF. Survival analysis shows lower graft survival for retransplants in the case of DGF. This study opens the possibility of identifying additional risk factors for patients undergoing retransplant surgeries.

Suicide amongst transplant recipients: Trends and unique risk factors.

INTRODUCTION: There are higher rates of depression and suicidal ideation among those with chronic diseases, including end-stage renal disease, diabetes mellitus and liver disease. Suicide is the tenth leading cause of death worldwide and is more prevalent among transplant recipients. Although transplantation has the potential to improve quality of life, many transplant recipients commit suicide each year. The extent to which sex, race, age, type of insurance coverage, time on waitlist, comorbidities, immunosuppressive regimen and graft loss contribute to suicide risk in this population remains understudied. METHODS: We queried UNOS data collected between 1990 and 2019 to determine what risk factors contribute to suicide in the transplant population. Suicide mortality rate was calculated by determining the fraction of organ recipients who died by suicide since 1990 and was expressed as deaths per 100 000. Two groups (suicide and all other cause mortality) were compared via univariate and multivariate statistical analysis. Time to graft loss was estimated using a Kaplan Meier Product Limit method. A propensity score analysis was performed to match patients who committed suicide to those who did not, allowing us to balance the relatively small sample of size of the suicide cohort with the larger all other cause mortality group to minimize the effect of confounding variables. We estimated years of organ life lost using the restricted mean. Statistical significance was defined by p < .05. RESULTS: The data included 135 432 transplant deaths in total; the majority were kidney recipients-82 305 (61%). We determined suicide rates of .28%, .31%, and .44% for kidney, liver and pancreas, respectively, with an overall rate of .3%. Across all three organs the most significant risk factor was male sex. Non-Hispanic whites were also at elevated risk (OR = 2.16, p < .003). In the liver and kidney transplant groups, the odds of committing suicide were reduced by 4% with advancing age. The odds of taking one's own life was inversely related to BMI in the kidney and pancreas groups. We observed a doubling of suicide rates from .3% in 2014 to .6% in 2018. There were no other statistically significant correlations. CONCLUSION: Suicide is more prevalent among transplant recipients than in the general population. White males in particular are most at risk. The highest rate of suicide was in pancreas recipients. Advancing age and increasing BMI conferred some protective effect. There were no significant associations between suicide incidence and glucocorticoid use, type of insurance coverage, time on waitlist or graft loss. The phenomenon has become more prevalent in recent years.

Hospital Performance for Gastrointestinal Bleeding Mortality, Length of Stay, and Complication Rates in the USA.

BACKGROUND: Hospitals are held accountable for quality metrics, through public reporting programs and by payers. However, little is known about hospital performance in GIB nationally. METHODS: A retrospective longitudinal analysis utilizing Vizient's database was performed to identify GIB hospitalizations across 349 hospitals from 2016 to 2018. The primary outcome was risk-adjusted mortality; secondary outcomes included risk-adjusted length of stay and complication rate. Trends in performance were characterized using quintiles, with analysis of concordance within hospitals and across hospitals over time. Pearson's correlation coefficients were performed to assess the relationship among metrics. RESULTS: 28.1% of hospitals had a steadily improving risk-adjusted mortality index from 2016 to 2018, while 15.5% were steadily worsening in mortality. For LOS, 25.2% of hospitals were improving, while 22.4% deteriorated. For complication rate, 22.9% of hospitals steadily improved, while 19.2% of hospitals deteriorated. Although many hospitals improved substantially in one outcome, they did not necessarily improve in all outcomes. Of the 98 hospitals that steadily improved in mortality from 2016 to 2018, only 8 out of 98 steadily improved in all three outcomes (8.3%). Across all 3 years, mortality was weakly correlated with LOS (r = 0.22, p < 0.001), but not with the rate of complications (r = 0.08, p = 0.12). CONCLUSION: Hospital performance metrics for GIB, such as mortality, length of stay, and complication rate, are weakly correlated and thus likely measure different aspects of care. While many hospitals improved over time, few hospitals improved in all three metrics. Additionally, many hospitals are deteriorating over time, and further research is needed to determine which care processes are associated with better outcomes.

The Role of Telemedicine in Surgical Specialties During the COVID-19 Pandemic: A Scoping Review.

BACKGROUND: The objective of this study was to evaluate the current body of evidence on the use of telemedicine in surgical subspecialties during the COVID-19 pandemic. METHODS: This was a scoping review conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). MEDLINE via Ovid, PubMed, and EMBASE were systematically searched for any reports discussing telemedicine use in surgery and surgical specialties during the first period (February 2020-August 8, 2020) and second 6-month period (August 9-March 4, 2021) of the COVID-19 pandemic. RESULTS: Of 466 articles screened through full text, 277 articles were included for possible qualitative and/or quantitative data synthesis. The majority of publications in the first 6 months were in orthopedic surgery, followed by general surgery and neurosurgery, whereas in the second 6 months of COVID-19 pandemic, urology and neurosurgery were the most productive, followed by transplant and plastic surgery. Most publications in the first 6 months were opinion papers (80%), which decreased to 33% in the second 6 months. The role of telemedicine in different aspects of surgical care and surgical education was summarized stratifying by specialty. CONCLUSION: Telemedicine has increased access to care of surgical patients during the COVID-19 pandemic, but whether this practice will continue post-pandemic remains unknown.

Cabo Verde Telemedicine Program: An Update Report and Analysis of 2,442 Teleconsultations.

Introduction: The Cabo Verde Telemedicine program (CVTP) was established by the International Virtual e-Hospital Foundation using the Initiate-Build-Operate-Transfer strategy to improve access to specialty care for the population in the archipelago of Cabo Verde in 2012. Since its inception, the CVTP has proven a great success story of telemedicine in Africa. Our first report on the initial results of a nationwide CVTP was published in 2014. The aim of this article is to analyze the follow-up data and analyze the activity of CVTP. Methods: All telemedicine consultations of the CVTP from 2014 to 2018 were analyzed. Patient demographics, clinical discipline, and transfer status were analyzed. Categorical variables were compared with a chi-squared test. Results: There were 2,442 telemedicine consultations in 24 clinical programs performed during the study period. The most common clinical disciplines with >100 consultations were neurology, cardiology, orthopedic surgery, general surgery, endocrinology, otolaryngology, urology, and dermatology. Overall, the transfer rate was 34.3%. Conclusion: The nationwide CVTP continues to increase access to specialized care, prevent unnecessary and costly transfers, and has become a great success story of telemedicine in Africa. Moreover, this program should serve as a model for establishing island-nations telemedicine programs worldwide.

Telemedicine Consultation as an Indicator of Local Telemedicine Champions' Contributions, Health Care System Needs or Both: Tales from Two Continents.

Background: Telemedicine systems increase access to care, particularly in remote and developing countries. Nationwide telemedicine programs in Cabo Verde and Albania have been built by the International Virtual e-Hospital Foundation (IVeH) and based on the effective Initiate-Build-Operate-Transfer (IBOT) strategy. The aim of this study was to compare the clinical results between the two programs and examine the relationship between the clinical teleconsultations as an indicator of health care system needs and the contribution of local telemedicine champions. Methods: Data were prospectively collected between 2014 and 2018 from Albania and Cabo Verde. Telemedicine champions were defined as programs, physicians, or hospitals who have contributed at least 100 telemedicine consultations during the study periods. Chi-squared test was utilized to analyze the data. Results: There were 2,442 teleconsultations in Cabo Verde and 2,724 teleconsultations in Albania during the study periods. Using the 100-consultation benchmark as the indicator of telemedicine champion, we identified radiology (n = 1,061), neurotrauma (n = 742), and general neurology or stroke (n = 489) as champion clinical disciplines in Albania. With the same method of 100 consultations, we identified eight champion clinical disciplines in Cabo Verde, including neurology (n = 720), cardiology (n = 313), orthopedics (n = 190), surgery (143), endocrinology (141), otolaryngology (n = 139), urology (n = 139), and dermatology (126). The patient transfer/nontransfer ratio was 0.5 in Cabo Verde and 0.3 in Albania (p < 0.001). Three hospitals in Albania and eight community hospitals/health care centers in Cabo Verde requested the majority of teleconsultations. Two main hospitals in Cabo Verde and Albania responded to the consultations. Conclusion: The successful implementation of a telemedicine program depends on many factors. However, physician champions, who eventually create clinical discipline champions, and represent the hospital champions, are the backbone of the sustainability and progress of any telemedicine program. The number of consultations reflects the lack of local specialty expertise to provide health care service and thus can be used for future planning and investment.

Kidney and pancreas transplant recipients undergoing cholecystectomy experience superior outcomes in transplant centers.

BACKGROUND: This retrospective analysis aims to identify differences in surgical outcomes between pancreas and/or kidney transplant recipients and the general population undergoing cholecystectomy. METHODS: Multivariate logistic regression and linear regression tests computed odds ratios (OR) and coefficients of the linear regression by analyzing weighted data from the NIS database between 2005 and 2014 to identify differences in mortality, morbidity, length of stay (LOS) and costs amongst KTx, PTx, PKTx, and non-Tx undergoing cholecystectomy in all centers and transplant centers. RESULTS: Overall 6007 KTx, 164 PTx, 535 PKTx, and 4,207,241 non-Tx met the inclusion criteria. Mortality from cholecystectomy was 1.0%. Transplant recipients did not experience a significant increase in mortality. However KTx and PTx suffered increased morbidity risks (KTx OR1.244 p < 0.01; PTx OR2.165 p < 0.01) compared to non-Tx. However transplant recipients did not incur an increased morbidity risk in transplant centers. CONCLUSION: Transplant recipients undergoing cholecystectomy should be counseled about their increased complication risks. Surgeons should consider transferring KTx and PTx to transplant centers for their cholecystectomy procedure to mitigate these risks.

A propensity-matched analysis of contemporary outcomes of blunt popliteal artery injury.

OBJECTIVE: Traumatic popliteal artery injury is associated with an increased propensity for limb loss, morbidity, and mortality above an already elevated baseline risk to life and limb. Previous studies of outcomes in this patient group have been limited by selection bias. This study analyzed outcomes after blunt popliteal artery injury using propensity matching to reduce confounding variables associated with multiple mechanisms of traumatic vascular injury and to identify factors associated with amputation. METHODS: A retrospective review was conducted of prospectively collected data from the National Trauma Data Bank. Patients were identified using International Classification of Diseases, Ninth Revision codes related to patterns of blunt injury associated with popliteal arterial injury or intervention. Using Trauma Quality Improvement Program variables as a reference, specific characteristics were collected. Variables found significant on univariate analysis were used to generate propensity-matched amputation and nonamputation cohorts. Multivariate logistic regression was used to assess for risk factors associated with amputation and inpatient mortality. RESULTS: In total, 3029 patients with blunt popliteal artery injury were identified; 628 (20.7%) underwent amputation. Patients who underwent amputation presented with more frequent hypotension (systolic blood pressure of 0-99 mm Hg, 22.7% vs 12.8%; P < .001) and tachycardia (heart rate >120 beats/min, 28.5% vs 14.5%; P < .001). Limb loss was also associated with concurrent popliteal vein injury (18.3% vs 8.7%; P < .001) and tibial nerve injury (5.3% vs 1.3%; P < .001) as well as with elevated Injury Severity Score (median, 13 vs 9; P < .001) and lower extremity Abbreviated Injury Scale score (3 vs 2; P < .001). Subsequently, 794 patients were divided into equal number propensity-matched amputation and nonamputation cohorts. Regression analysis revealed that patients with diabetes mellitus (odds ratio [OR], 1.763; P = .049), popliteal vein injury (OR, 1.657; P = .012), or tibial nerve injury (OR, 3.537; P = .007) were more likely to undergo amputation. Further regression analysis with patients matched for Injury Severity Score revealed that age ≥86 years (OR, 38.092; P = .009), patellar fracture (OR, 3.445; P = .036), and elevated Abbreviated Injury Scale score (OR, 1.101; P < .001) were associated with higher risk of inpatient death. CONCLUSIONS: Trauma patients who sustain blunt popliteal artery injury are at an increased risk of amputation. Propensity-matched analysis revealed that concurrent popliteal vein and tibial nerve injury but not severity of tissue injury predicted limb loss.

Increased Access to Care through Telemedicine in Albania: An Analysis of 2,724 Patients.

Introduction: The Integrated Telemedicine and e-Health program (ITeHP) of Albania, built by the International Virtual e-Hospital Foundation (IVeH), has improved access to high-quality health care, particularly in high demanding specialty disciplines. We aimed to test the hypothesis that the majority of patients in remote and regional hospitals can be managed using telemedicine and will prevent unnecessary transfers. Methods: A retrospective analysis of prospectively collected data of patients seen between January 2014 and September 2018 was conducted. Patient demographics, type of teleconsultation modality used, and patient disposition were analyzed. The comparison of continuous data was performed with t-test or Mann-Whitney test. The categorical data were tested with chi-squared test and analysis of variance. Results: There were 2,842 patients seen in all the clinical disciplines during the study period. We excluded tele-autism and incomplete data. There were 2,724 records eligible for study. The most frequent consulting clinical programs (82.9%) were teleradiology (39.0%), teleneurotrauma (27.2%), and teletestroke (16.7%). The majority of patients (77.9%) were kept at regional centers and did not require transfer (p < 0.001) to a tertiary center. Of those transferred, 70.3% were male (p < 0.001), of which 81.6% were for transferred due to neurotrauma. Conclusion: The telemedicine program in Albania has improved access to specialized care in a number of specialty clinical disciplines, particularly in potentially life-threatening and time-sensitive conditions such as neurotrauma. Almost 80% of patients did not require transfer to tertiary centers and were kept for further treatment at the regional centers.

A comparison of pediatric ocular injuries based on intention in patients admitted with trauma.

PURPOSE: Pediatric ocular trauma is a major source of morbidity and blindness and the number of epidemiological studies is incommensurate with its significance. We sought to determine differences in epidemiologic patterns of pediatric ocular injuries based on intention. METHODS: A retrospective review of the National Trauma Data Bank (2008-2014) was performed and patients < 21 years old, admitted with trauma and ocular injury, were identified using ICD-9CM codes. Demographic data, types of injury and external circumstances including intention were tabulated and analyzed with students' t and chi-squared tests and logistic regression. Statistical significance was set at p < 0.05. RESULTS: Fifty-eight thousand seven hundred sixty-five pediatric patients were admitted for trauma and ocular injuries. The mean(SD) age was 11.9(6.9) years. Most patients were male (68.7%) and White (59.1%). Unintentional injuries (76.3%) were mostly associated with falls (OR = 13.4, p < 0.001), assault (16.3%) with firearms (OR = 9.15, p < 0.001) and self-inflicted trauma (0.7%) also with firearms (OR = 44.66, p < 0.001). There was increasing mean(SD) age from unintentional, 12.9(6.6) years and assault 12.3(8.1) years to self-inflicted trauma, 17(3.4) years. The 0-3 year age group had highest odds of open adnexa wounds (OR = 30.45, p < 0.001) from unintentional trauma, and traumatic brain injury (TBI) (OR = 5.77, p < 0.001) and mortality (OR = 8.52, p < 0.001) from assault. The oldest 19-21 year group, had highest odds visual pathway injuries (OR = 8.34, p < 0.001) and TBI (OR = 1.54, p = 0.048) from self-inflicted trauma and mortality (OR = 2.08, p < 0.001) from unintentional trauma. CONCLUSION: Sight-threatening injuries were mostly associated with unintentional trauma in the youngest group and self-inflicted trauma in the oldest group. Patterns emerged of associations between demographic groups, mechanisms, types of injury and associated TBI with intention of trauma.

Prognostic indicators for early mortality after tracheostomy in the intensive care unit.

BACKGROUND: Tracheostomy is indicated for patients requiring prolonged mechanical ventilation. The aim of this study is to identify prognostic indicators for early mortality after tracheostomy to potentially avoid futility in the intensive care unit. METHODS: Patients who underwent tracheostomy and died within 30 d of admission (futile group) were compared with patients who underwent tracheostomy and survived more than 30 d after admission (nonfutile group). Categorical data were analyzed using chi-square and Fisher's exact tests. Continuous variables were analyzed using T-tests and Mann-Whitney U tests. Prognostic factors were evaluated with univariable and multivariable logistic regression analyses. RESULTS: Overall, 88.3% of patients underwent nonfutile tracheostomy, while 11.7% underwent futile tracheostomy. Serum albumin level (1.5 g/dL versus 1.9 g/dL, P = 0.040) and mechanical ventilation duration before procedure (10 versus 12 d, P = 0.029) were significantly less in the futile group. Hypoalbuminemia (<2 g/dL) and preoperative mechanical ventilation ≤10 d were also predictive of futile tracheostomy in multivariable analysis. CONCLUSIONS: Hypoalbuminemia may serve as a prognostic indicator and risk factor for early mortality after tracheostomy. In patients with hypoalbuminemia, treatment of underlying disease processes and trending serum albumin level recovery in response to treatment may provide some insight to clinicians with regard to timing of tracheostomy. Better prognostic tools are still needed for critically ill patients to avoid futility in the intensive care unit. In this cohort, 88.3% of patients undergoing tracheostomy survived past 30 d.

Eastern Association for the Surgery of Trauma (EAST) vs Western Trauma Association (WTA): How a Level 1 Trauma Center Splits the Difference in Resuscitative Thoracotomy.

Background Resuscitative thoracotomy (RT) is performed in severe trauma cases as a final lifesaving effort. Prominent, yet differing, practice management guidelines exist from Eastern Association for the Surgery of Trauma (EAST) and Western Trauma Association (WTA). This study evaluates all RTs performed from 2012 to 2019 at an urban Level 1 trauma center for management guideline indication and subsequent outcomes. Methods Our trauma registry was queried to identify RT cases from 2012 to 2019. Data was collected on patient demographics, prehospital presentation, cardiopulmonary resuscitation (CPR) requirements, and resuscitation provided. Survival to the operating room, intensive care unit, and overall were recorded. Information was compared with regard to EAST and WTA criteria. Results Eighty-seven patients who underwent RTs were included. WTA guidelines were met in 78/87 (89.7%) of cases, comparatively EAST guidelines were met in every case. Within the EAST criteria, conditional and strong recommendations were met in 70/87 (80.4%) and 17/87 (19.5%) of cases, respectively. In nine cases (10.3%) indications were discordant, each meeting conditional indication by EAST and no indication by WTA. All patients that survived to the operating room (OR), ICU admission, and overall met EAST criteria. Conclusion All RTs performed at our Level 1 trauma center met indications provided by EAST criteria. WTA guidelines were not applicable in nine salvaging encounters due to the protracted duration of CPR before proceeding to RT. Furthermore, more patients that survived to OR and ICU admission met EAST guidelines suggesting an improved potential for patient survivability. As increased data is derived, management guidelines will likely be re-established for optimized patient outcomes.

Immediate postoperative sonography of renal transplants: vascular findings and outcomes.

OBJECTIVE: The purpose of this study was to determine the frequency and types of significant vascular findings on bedside sonography immediately after renal transplantation and which abnormalities would suggest a benefit from early surgical revision. MATERIALS AND METHODS: Five hundred seventy-five renal transplant sonograms obtained within 4 hours of surgery were retrospectively reviewed for major vascular abnormalities: lack of renal artery (RA) or renal vein (RV) flow, elevated peak systolic velocity (PSV)>300 cm/s, parvus tardus waveforms, and markedly decreased or no color parenchymal flow. Clinical outcomes of abnormal cases were reviewed, including reoperations and percutaneous interventions. RESULTS: Thirty-two (5.6%) patients underwent repeat surgery within the first week, 16 for nonvascular causes. Forty-seven (8.2%) patients had positive sonography findings. In 16 patients, sonography impacted the decision for reoperation, with 14 confirmed vascular diagnoses: compartment syndrome (n=7), RV thrombosis (n=3), RA thrombosis (n=1), RA and RV thromboses (n=2), and vascular steal (n=1). All were salvaged except the three RV thromboses. Two patients had no vascular abnormality at surgery. All 16 had markedly decreased color flow and varying abnormalities of PSV and waveforms. Outcomes of the remaining 31 cases were infarct (n=1), renal or iliac artery stenoses eventually requiring stents (n=4), and normalized (n=26). These 26 had elevated PSV with normal or near-normal color flow. Unpaired Student t tests showed no significant difference in PSV between patients requiring surgery or stents and those who normalized (p=0.34). CONCLUSION: Immediate postoperative sonography has a spectrum of vascular findings, of which markedly decreased color flow is most likely to benefit from immediate reoperation.

Disparities Associated with Discharge Patterns in Firearm-Associated Ocular Trauma.

Importance: Firearm injuries are associated with devastating visual outcomes. Several studies have demonstrated disparities in trauma care and discharge to rehabilitation and other advanced care facilities (ACFs) due to race and ethnicity and insurance status. The identification of possible disparities in disposition of patients admitted with firearms-associated ocular injuries (FAOIs) is a crucial step in moving toward health equity. Objective: To describe disposition patterns following admission for FAOI trauma. Design, Setting, and Participants: This retrospective analysis of National Trauma Data Bank (NTDB) from 2008 through 2014 used hospitalized trauma cases from over 900 US facilities detailed in the NTDB. Participants included patients admitted with ocular injuries. Statistical analysis was conducted between April 16, 2017, and December 15, 2021. Exposure: Firearm injuries. Main Outcomes and Measures: Patients admitted with FAOIs were identified using International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes and E-codes. Demographic data, location, injury type and severity, and insurance status were documented. The primary outcome was the odds of discharge to ACFs. Results: A total of 8715 of 235 254 firearms injuries involved the eye (3.7%). Of the 8715 included patients, 7469 were male (85.7%), 3050 were African American (35.0%), and 4065 White (46.6%), with a mean (SD) age of 33.8 (16.9) years. Common payments were government insurance (31.5%), self-paid insurance (29.4%), and commercial insurance plans (22.8%). Frequent dispositions were home (48.8%) and ACF (20.5%). Multivariate analysis demonstrated that the following factors were associated with the highest odds of discharge to an ACF: hospital stays 6 days or longer (odds ratio [OR], 3.05; 95% CI, 2.56-3.63; P < .001), age 65 years or older (OR, 2.94; 95% CI, 1.94-4.48; P < .001), associated traumatic brain injury (OR, 2.32; 95% CI, 1.94-2.78; P < .001), severe traumatic brain injury (OR, 2.10; 95% CI, 1.79-2.46; P < .001), and very severe Injury Severity Score (OR, 2.22; 95% CI, 1.88-2.62; P < .001). White race (OR, 2.00; 95% CI, 1.71-2.33; P < .001) was associated with higher odds than Medicare insurance (OR, 1.64; 95% CI, 1.16-2.31; P = .01). Conclusions and Relevance: These findings suggest that older, more severely injured, Medicare-insured, or White patients have higher odds of ACF placement than younger, less severely injured, otherwise insured, and Black and Hispanic patients. This study is limited by its retrospective nature and the study team was unable to explore the basis for these disposition differences. Nevertheless, this work highlights that disparities may exist in disposition after FAOIs that may limit the rehabilitation potential of specific populations.

Improved Medication Adherence with the Use of Extended-Release Tacrolimus in Liver Transplant Recipients: A Pilot Randomized Controlled Trial.

Background: Nonadherence to immunosuppression in liver transplant recipients (LTRs) leads to deterioration in health outcomes. Once-dailyextended-release tacrolimus (TAC-ER) may improve adherence when compared to twice-dailyimmediate-release tacrolimus (TAC-IR). Methods: We conducted a randomized controlled study to evaluate medication adherence, clinical efficacy, and safety of TAC-ER in stable LTR. All patients >18 years who underwent liver transplantation before 6 months were eligible. Patients were randomized 1 : 1 to continued TAC-IR or conversion to TAC-ER. The primary outcome was change in medication adherence from baseline to 9 months, assessed using BAASIS. Secondary outcomes were tacrolimus trough levels, safety, and quality of life. Results: Thirty-one patients were consented and randomized to either of the two groups: conversion to TAC-ER (n = 15) or continued TAC-IR (n = 16). Six patients in the TAC-ER group withdrew after randomization due to apprehension about switching medication (n = 2), unwillingness to travel (n = 2), and increased liver tests after conversion (n = 2, both were acute rejections despite therapeutic tacrolimus levels and were considered unrelated to TAC-ER). We compared the results of nine patients in the TAC-ER group that completed the study with those of sixteen in the TAC-IR group. At baseline, there was no difference in tacrolimus trough levels between groups. Improved adherence was observed in the TAC-ER group as 100% of patients reported at least one period of full adherence during the study period (100% vs. 62.6%, p = 0.035). Tacrolimus trough levels and liver tests were comparable between groups throughout the study. There were no differences in eGFR, HbA1c, or QoL between the groups. Conclusion: TAC-ER improved medication adherence while maintaining comparable trough levels, liver function, and QoL as TAC-IR in LTR.

Laparoscopic Cholecystectomy in the Time of Coronavirus: A Level-1 Trauma Center's Experience.

INTRODUCTION: Laparoscopic cholecystectomy (LC), one of the most common surgical procedures performed in the U.S., offers a window into the effects of the COVID-19 pandemic on routine surgical care. The purpose of our study was to analyze the effects of the COVID-19 pandemic at a Level-1 trauma center on the performance rate of non-elective LC over time. METHODS: A retrospective chart review from July 2019 to December 2020 identified all non-elective LC cases performed at a level-1 trauma center. Patients were categorized into 4 temporal phases along the course of the pandemic based on statewide incidence data on COVID-19: pre-pandemic, peak 1, recovery, and peak 2. We compared the phases based on demographic information and outcomes. RESULTS: In total, 176 patients were reviewed. The performance rate in cases/day varied as follows: pre-pandemic .61, 1st peak .34, recovery .44, and 2nd peak .53. The complication rate was highest in the 2nd peak (16%) (P < .05). Compared to the pre-pandemic period, the intra-pandemic period had a higher incidence of complicated gallbladder disease (P < .05). In the non-elderly subgroup, complicated gallbladder disease was significantly more prevalent in the intra-pandemic period compared to the pre-pandemic period (25% vs 10%, P < .05). CONCLUSIONS: Our data suggests a learning curve throughout the course of the pandemic, reflecting a stepwise increase in the performance rate of LC. The higher incidence of complicated gallbladder disease in the intra-pandemic period may imply patient hesitancy to seek routine surgical care, especially among younger patients.

Combination of Lactate and Base Deficit Levels at Admission to Predict Mortality in Blunt Trauma Patients.

INTRODUCTION: Elevated lactate levels are associated with increased mortality in both trauma and non-trauma patients. The relation between base deficit (BD) and mortality is less clear. Traumatologists debate the utility of elevated lactate (EL) versus BD in predicting mortality. We hypothesized that EL (2mmol/L to 5mmol/L) and BD (≤-2mmol/L) in combination could predict mortality in blunt trauma patients.  Methods: This is a retrospective analysis of the trauma registry from 2012 to 2021 at a level 1 trauma center. Blunt trauma patients with admission lactate and BD values were included in the analysis. Exclusion criteria were age <18, penetrating trauma, unknown mortality, and unknown lactate or BD. Logistics regression of the total 5153 charts showed 93% of the patients presented with lactate levels <5mmol/L, therefore patients with lactate >5mmol/L were excluded as outliers. The primary outcome was mortality. RESULTS: A total of 4794 patients (151 non-survivors) were included in the analysis. Non-survivors had higher rates of EL + BD (35.8% vs. 14.4%, p <0.001). When comparing survivors and non-survivors, EL + BD (OR 5.69), age >65 (5.17), injury severity score (ISS) >25 (8.87), Glasgow coma scale <8 (8.51), systolic blood pressure (SBP) <90 (4.2), and ICU admission (2.61) were significant predictors of mortality. Other than GCS <8 and ISS >25, EL + BD had the highest odds of predicting mortality. CONCLUSION: Elevated lactate + BD on admission in combination represents a 5.6-fold increase in mortality in blunt trauma patients and can be used to predict a patient's outcome on admission. This combination variable provides an additional early data point to identify patients at elevated risk of mortality at the moment of admission.

Ethnic and Racial Diversity Among Surgeon and Non-Surgeon Deans of Allopathic Medical Schools.

INTRODUCTION: Previous publications have assessed the diversity among medical students, residents, faculty, and department leaders in surgery and medicine overall. We aim to evaluate the diversity among medical school deans in the United States. We quantify and compare the representation of women and underrepresented minority surgeon and non-surgeons. METHODS: 151 allopathic medical schools were included. Data regarding demographics, education, training, and previous leadership position were collected from institutional websites, online resources, and July 2021 Association of American Medical Colleges Council of Deans. Demographics for surgeon and non-surgeon were compared using chi square and logistic regression with 5% significance interval. RESULTS: 21.9% (n = 33) of all medical school deans were surgeons. 21.2% (n = 7) were women, which was not significantly different from non-surgeons (22%, P = .92). All the women surgeons were non-Hispanic white, similar to all deans (P = .83). 78.8% (n = 26) of all surgeon deans were non-Hispanic White compared to 84.7% (n = 100) overall (P = .28). There were 13 Black deans, four of whom were surgeons, and only one Hispanic dean, who was not a surgeon. Surgeons were more likely to be fellows of their professional society (P = .012). CONCLUSION: The demographic diversity of surgeon and non-surgeon US medical school deans is not significantly different. The deficiencies in leadership diversity in medicine persists among medical school deans. There remains substantial room to improve the representation of women and underrepresented minorities as deans.
