The Respiratory Rate: A Neglected Triage Tool for Pre-hospital Identification of Trauma Patients.

BACKGROUND: Under-triaged trauma patients have worse clinical outcomes. We evaluated the capability of four pre-hospital variables to identify this population at the lowest level trauma activation (level 3). METHODS: A retrospective review of adult trauma activations from 2004 to 2014 was completed. Pre-hospital vital signs and Glasgow Coma Scale were converted to categorical variables. Patients were under-triaged based on meeting current level 1 or 2 criteria, or requiring a pre-defined critical intervention. Logistic regression was used to determine the association between the pre-hospital variables and under-triaged patients. Odds ratios and 95% confidence intervals were calculated for a comprehensive model, grouping all causes of under-triage as a single unit, and 16 individual models, one for each under-triage criterion. A new level 2 criterion was generated and internally validated. RESULTS: In total, 12,332 activations occurred during the study period. Four hundred and sixty-six (5.9%) patients were under-triaged. Compared to patients with a normal respiratory rate (RR), tachypneic patients were more likely to be under-triaged for any reason, OR 1.7 [1.3-2.1], p < 0.001. In the individual event analysis, tachypneic patients were more likely to have flail chest, OR 22 [2.9-168.3], p = 0.003; require a chest tube, OR 3 [1.8-4.9], p < 0.001; or require emergent intubation, OR 1.6 [1.1-2.8], p = 0.04, compared to patients with a normal RR. The data-driven triage modification was tachypnea with suspected thoracic injury which reduced the under-triage rate by 1.2%. CONCLUSION: Tachypnea with suspected thoracic injury is the strongest level 2 triage modification to reduce level 3 under-triage.

Assessment of three point-of-care platelet function assays in adult trauma patients.

BACKGROUND: Antiplatelet (AP) medication use is common among trauma patients and is associated with poor outcomes. Management options for platelet dysfunction in trauma patients are controversial, expensive, and potentially harmful. Although light transmission platelet aggregometry is considered the standard test to assess platelet function, it is cumbersome and not generally available. Currently, there are no widely accepted platelet function point-of-care tests for acute trauma. STUDY DESIGN: Prospective observational study from 2014 to 2015. Baseline Multiplate aggregometry aspirin area under the platelet aggregation curve (ASPI AUC), Thrombelastography Platelet Mapping percent inhibition of arachidonic acid (TEG-PM AA), and VerifyNow Aspirin Test (ARU) were compared for ability to detect any AP medication use (aspirin or clopidogrel), platelet dysfunction, and identify patients at risk for intracranial hemorrhage (ICH) progression by calculating the area under receiver operating characteristic curves (AUC), sensitivity, specificity, and positive and negative predictive values. Adenosine diphosphate assays were similarly evaluated. RESULTS: Sixty-four patients were enrolled, 25 were taking AP medications. AP patients were older (71.6 versus 35.0 y, P < 0.001) and received more platelet transfusions, but other baseline characteristics were similar. Median ASPI AUC (22.0 versus 53.5 P < 0.001) and VerifyNow ARU (503.5 versus 629.0, P < 0.001) were lower, whereas TEG-PM AA (51.8% versus 18.3%, P < 0.001) was higher in AP patients. Multiplate ASPI AUC, TEG-PM AA percent inhibition, and VerifyNow ARU could identify AP medication use (AUC: 0.90, 0.77, and 0.90, respectively). Adenosine diphosphate assays did not correlate with AP medication use in this population. TEG-PM AA percent inhibition and VerifyNow ARU correlated well with Multiplate ASPI AUC to identify platelet dysfunction (AUC: 0.78, 0.89, respectively). ICH occurred in 29 patients; 12 of which had progression of their injury. ASPI AUC (AUC: 0.50) and VerifyNow ARU (AUC: 0.59) did not correlate, and TEG-PM AA percent inhibition (AUC: 0.66) minimally correlated with progression. CONCLUSIONS: Multiplate, TEG-PM, and VerifyNow are useful point-of-care tests which identify AP medication use and platelet dysfunction in trauma patients. Initial TEG-PM AA percent inhibition may be associated with risk for ICH progression. However, additional large, prospective studies are needed.

Robotic navigational bronchoscopy in a thoracic surgery practice: Leveraging technology in the management of pulmonary nodules.

Objectives: Robotic navigational bronchoscopy is increasingly used to improve diagnostic yield for pulmonary nodules compared with the 50% to 60% obtained by standard bronchoscopy; however, safety and efficacy data are limited to small series. The aim of this study was to evaluate diagnostic yield and clinical outcomes in a large multisurgeon single-center cohort. Methods: All patients who underwent robotic navigational bronchoscopy and biopsy from September 2020 to October 2022 were identified from a prospective institutional registry. The primary outcome was diagnostic yield. The secondary outcome was diagnostic yield for molecular testing. Results: A total of 503 nodules were biopsied during the study period. Median nodule size was 2.1 cm. Overall diagnostic yield was 87.9%. Factors associated with increased diagnostic yield were decreased time from date of planning computed tomography to procedure date (odds ratio, 0.98; 95% CI, 0.96-0.99; P = .04) and greater nodule size (odds ratio, 1.03; 95% CI, 1.01-1.07; P = .02) per 0.1-cm increment. Molecular analysis was sent in 101 patients and was sufficient in 90% of cases. Complications occurred in 22 (5%) patients, including 13 (3.1%) with pneumothoraxes (7 patients requiring a chest drain), and 5 (1.2%) patients had bleeding requiring intraprocedural bronchial intervention. A total of 41 patients were consented for biopsy and resection during a single anesthetic event. Four of these cases were stopped at robotic navigational bronchoscopy due to an alternative diagnosis. Mean length of stay was 3.4 ± 1.1 days. There were no major complications. Conclusions: This study suggests robotic navigational bronchoscopy has a high diagnostic yield and obtains adequate tissue for molecular analysis critical for selection of targeted therapies. With careful patient selection robotic navigational bronchoscopy can be combined with surgery to treat lung cancer as a single procedure with low complication rates.

Interviews During the Pandemic: A Thoracic Education Cooperative Group and Surgery Residents Project.

BACKGROUND: The 2020 interview cycle for cardiothoracic fellowships was affected by the coronavirus-19 pandemic. Many programs shifted from in-person to virtual interviews. We evaluated applicant perceptions of the various formats. METHODS: All 2019-2020 cardiothoracic fellowship applicants received an electronic survey after completion of the match process. The survey assessed number of in-person/virtual interviews completed, perception of efficacy, and likelihood of ranking a program based on format, and strengths/inadequacies of virtual interviews. RESULTS: Response rate was 36% (48 of 133). Seventy-three percent of respondents (35 of 48) interviewed with more than 10 programs. Fifty-two percent of respondents (25 of 48) were able to schedule additional interviews once virtual formats were available. A slight majority (56%, 27 of 48) ranked a program at which they had an in-person interview as their first choice. Interviewing at more than 10 programs was associated with an increased likelihood of successfully matching at a program (P = .02). Overwhelmingly, respondents favored an in-person component to the interview process (96%, 46 of 48). Few respondents (29%, 14 of 48) thought they could adequately evaluate a program virtually. The factors that had the highest percentages of adequate portrayal during virtual interviews were the didactic schedule/curriculum (81%, 39 of 48) and case number/autonomy (58%, 28 of 48). The factors with the lowest percentages were culture/personality (19%, 9 of 48) and city/lifestyle (15%, 7 of 48). CONCLUSIONS: Applicants strongly favored an in-person component to interviews, highlighting potential deficiencies in the virtual interview process. Programs should consider the addition of virtual tours of their hospitals, narrations from staff, and vignettes from current fellows about lifestyle and well-being.

Same session bilateral ureteroscopy is safe and efficacious.

PURPOSE: Bilateral ureteroscopy can be done in 1 sitting, obviating the need for multiple procedures. We analyzed our experience with same session bilateral ureteroscopy to determine its safety and efficacy. MATERIALS AND METHODS: In this retrospective study of a 9-year period at Emory University Hospital 1,575 consecutive ureteroscopic procedures were done, of which 95 (6.0%) were done as same session bilateral ureteroscopy, thus constituting our study cohort. Bilateral procedures were performed for urolithiasis in 71 cases, urothelial carcinoma in 9, ureteral stricture in 2 and another indication in 13. Patients were followed at least 1 month postoperatively to evaluate procedural success and assess perioperative complications. RESULTS: Mean age of the 44 male and 40 female patients was 49.8 years. Multiple procedures were done in 9 patients and same session bilateral ureteroscopy was done in 93 of 95 (98%). Intraoperative and postoperative (greater than 1 month) bilateral stone-free rates were 86% and 64%, respectively. The mean change in serum creatinine postoperatively was 0.02 mg/dl (range -0.9 to 1.3). No patient had acute postoperative azotemia. Postoperative complications in 9.7% of patients included pain necessitating an emergency room visit in 4, pyelonephritis/urinary tract infection in 2, and urinary retention, intractable stent pain leading to early removal and urosepsis/death in 1 each. CONCLUSIONS: Same session bilateral ureteroscopy is efficacious and safe to evaluate and treat upper tract pathology. While most complications are minor, they may be higher than that typically reported for unilateral ureteroscopic procedures.

The Thoracic Surgery Residents Association: Past contributions, current efforts, and future directions.

OBJECTIVE: The Thoracic Surgery Residents Association (TSRA) is a resident-led organization established in 1997 under the guidance of the Thoracic Surgery Directors Association to represent the interests and educational needs of cardiothoracic surgery residents. We aim to describe the past contributions, current efforts, and future directions of the TSRA within a conceptual framework of the TSRA mission. METHODS: Primary review of educational resources was performed to report goals and content of past contributions. TSRA Executive Committee input was used to describe current resources and activities, as well as the future goals of the TSRA. Podcast analytics were performed to report national and global usage. RESULTS: Since 2011, the TSRA has published 3 review textbooks, 5 reference guides, 3 test-preparation textbooks, 1 supplementary publication, and 1 multiple-choice question bank and mobile application, all written and developed by cardiothoracic surgery trainees. In total 108 podcasts have been recorded by mentored trainees, with more than 175,000 unique listens. Most recently, the TSRA has begun facilitating trainee submissions to Young Surgeon's Notes, fostered a trainee mentorship program, developed the monthly TSRA Newsletter, and established a wide-reaching presence on Facebook, Twitter, and Instagram to help disseminate educational resources and opportunities for trainees. CONCLUSIONS: The TSRA continues to be the leading cardiothoracic surgery resident organization in North America, providing educational resources and networking opportunities for all trainees. Future directions include development of an integrated disease-based resource and continued collaboration within and beyond our specialty to enhance the educational opportunities and career development of cardiothoracic trainees.

Comparative analysis of 1152 African-American and European-American men with prostate cancer identifies distinct genomic and immunological differences.

Racial disparities in prostate cancer have not been well characterized on a genomic level. Here we show the results of a multi-institutional retrospective analysis of 1,152 patients (596 African-American men (AAM) and 556 European-American men (EAM)) who underwent radical prostatectomy. Comparative analyses between the race groups were conducted at the clinical, genomic, pathway, molecular subtype, and prognostic levels. The EAM group had increased ERG (P < 0.001) and ETS (P = 0.02) expression, decreased SPINK1 expression (P < 0.001), and basal-like (P < 0.001) molecular subtypes. After adjusting for confounders, the AAM group was associated with higher expression of CRYBB2, GSTM3, and inflammation genes (IL33, IFNG, CCL4, CD3, ICOSLG), and lower expression of mismatch repair genes (MSH2, MSH6) (p < 0.001 for all). At the pathway level, the AAM group had higher expression of genes sets related to the immune response, apoptosis, hypoxia, and reactive oxygen species. EAM group was associated with higher levels of fatty acid metabolism, DNA repair, and WNT/beta-catenin signaling. Based on cell lines data, AAM were predicted to have higher potential response to DNA damage. In conclusion, biological characteristics of prostate tumor were substantially different in AAM when compared to EAM.

Late Type A Dissection After Transfemoral Aortic Valve Replacement.

An 87-year-old woman had residual moderate to severe aortic insufficiency following transcatheter aortic valve replacement. A year later, she developed extensive Stanford type A aortic dissection originating at the supra-annular aortic edge of the transcatheter aortic valve replacement nitinol frame. Dissection repair, frozen elephant trunk with exclusion of prior insufficiency while preserving the transcatheter aortic valve replacement valve was performed. (Level of Difficulty: Beginner.).

Dynamic hydrodistention of the ureteral orifice: a novel grading system with high interobserver concordance and correlation with vesicoureteral reflux grade.

PURPOSE: We evaluated the usefulness and interobserver concordance of a novel grading system for dynamic ureteral hydrodistention. MATERIALS AND METHODS: Between May 1, 2002 and July 1, 2008 the hydrodistention grade in 697 ureters was prospectively assigned and recorded, including H0-no hydrodistention, H1-ureteral orifice open but tunnel not evident, H2-tunnel seen only and H3-extravesical ureter visualized. Specifically 489 refluxing ureters (vesicoureteral reflux group) were compared to 100 normal control ureters (normal control group). Additionally, the posttreatment hydrodistention grade in 56 ureters in which surgery for reflux failed was compared to that in 52 ureters with successful surgery. Hydrodistention grades assigned to an additional 77 ureters by 3 blinded observers were compared to assess the interobserver concordance of this system. RESULTS: Vesicoureteral reflux and hydrodistention grades correlated significantly (p <0.001). Ureters with a higher reflux grade also showed a higher hydrodistention grade. The normal control group (mean +/- SEM hydrodistention grade 0.62 +/- 0.07) showed a statistically lower hydrodistention grade than the reflux groups (overall mean hydrodistention grade 2.26 +/- 0.01). Mean posttreatment hydrodistention grade in the failed reflux surgery group was statistically higher than that in the mean successful reflux surgery group (2.03 +/- 0.09 vs 1.33 +/- 0.08). By defining the degree of hydrodistention as normal (H0-H1) and abnormal (H2-H3) the concordance between observers was 95% and 96%. CONCLUSIONS: The dynamic hydrodistention classification is a reliable method of evaluating the presence or absence of vesicoureteral reflux as it correlates significantly with radiographic reflux grade. It has high interobserver concordance.

Consumption of alcohol leads to platelet inhibition in men.

INTRODUCTION: Alcohol consumption has been shown to alter coagulation. However, thromboelastography with platelet mapping (TEG PM) to evaluate platelet function has not been studied. METHODS: A prospective, non-randomized study of healthy volunteers was conducted. Baseline TEG PM were collected. Subjects consumed alcoholic or non-alcoholic beverages for 2 h. Repeat TEG PM was collected. RESULTS: Fifty-four volunteers entered either the experimental group (EG, 17 women and 16 men) or control group (CG, 11 women and 10 men). After 2 h of alcohol or non-alcoholic drink consumption the median breath alcohol level was 0.08 [IQR 0.05, 0.12] in the EG and 0.00 in the CG. After consumption of alcohol, male EG subjects demonstrated higher median Adenosine Diphosphate (ADP) inhibition of platelet function (15.7% [3.9, 39.3] vs 8.2% [0, 30.1), p = 0.035), but female subjects did not. There was no evidence of increased arachidonic acid (AA) platelet inhibition in the EG compared to CG. Clot strength (TEG maximum amplitude) was not different between groups. CONCLUSION: After consumption of alcohol, healthy male volunteers demonstrate ADP platelet inhibition by TEG PM.

Optimizing physician skill development for medical students: The four-part assessment.

BACKGROUND: Medical student performance has been poorly correlated with residency performance and warrants further investigation. We propose a novel surgical assessment tool to determine correlations with clinical aptitude. METHODS: Retrospective review of medical student assessments from 2013 to 2015. Faculty rating of student performance was evaluated by: 1) case presentation, 2) problem definition, 3) question response and 4) use of literature and correlated to final exam assessment. A Likert scale interrater reliability was evaluated. RESULTS: Sixty student presentations were scored (4.8 assessors/presentation). A student's case presentation, problem definition, and question response was correlated with performance (r = 0.49 to 0.61, p ≤ 0.003). Moderate correlations for either question response or use of literature was demonstrated (0.3 and 0.26, p < 0.05). CONCLUSION: Our four-part assessment tool identified correlations with course and examination grades for medical students. As surgical education evolves, validated performance and reliable testing measures are required.

The evolution of care improves outcome in blunt thoracic aortic injury: A Western Trauma Association multicenter study.

BACKGROUND: The management of blunt thoracic aortic injury (BTAI) has evolved radically in the last decade with changes in the processes of care and the introduction of thoracic endovascular aortic repair (TEVAR). These changes have wrought improved outcome, but the direct effect of TEVAR on outcome remains in question as previous studies have lacked vigorous risk adjustment and long-term follow-up. To address these knowledge gaps, we compared the outcomes of TEVAR, open surgical repair, and nonoperative management for BTAI. METHODS: Eight verified trauma centers recruited from the Western Trauma Association Multicenter Study Group retrospectively studied all patients with BTAI admitted between January 1, 2006, and June 30, 2016. Data included demographics, comorbidities, admitting physiology, injury severity, in-hospital care, and outcome. RESULTS: We studied 316 patients with BTAI; 57 (18.0%) were in extremis and died before treatment. Of the 259 treated surgically, TEVAR was performed in 176 (68.0%), open in 28 (10.8%), hybrid in 4 (1.5%), and nonoperative in 51 (19.7%). Thoracic endovascular aortic repair and open repair groups had similar Injury Severity Scale score, chest Abbreviated Injury Scale score, Trauma and Injury Severity Score, and probability of survival, but differed in median age (open: 28 [interquartile range {IQR}, 19-51]; TEVAR: 46 [IQR, 28-60]; p < 0.007), zone of aortic injury (p < 0.001), and grade of aortic injury (open: 6 [IQR, 4-6]; TEVAR: 2 [IQR, 2-4]; p < 0.001). The overall in-hospital mortality was 6.6% (TEVAR: 5.7%, open: 10.7%, nonoperative: 3.9%; p = 0.535). Of the 240 patients who survived to discharge, two died (one at 9 months and one at 8 years); both were managed with TEVAR, but the deaths were unrelated to the aortic procedure. Stent graft surveillance computed tomography scans were not obtained in 37.6%. CONCLUSIONS: The mortality of BTAI continues to decrease. Thoracic endovascular aortic repair, when anatomically suitable, should be the treatment of choice. Open repair remains necessary for more proximal injuries. Process improvement in computed tomography imaging in follow-up of TEVAR is warranted. LEVEL OF EVIDENCE: Therapeutic/care management, level III.

Damage control laparotomy utilization rates are highly variable among Level I trauma centers: Pragmatic, Randomized Optimal Platelet and Plasma Ratios findings.

BACKGROUND: Damage control laparotomy (DCL) is intended to limit deleterious effects from trauma-induced coagulopathy. DCL has been associated with mortality reduction, but may increase complications including sepsis, abscess, respiratory failure, hernia, and gastrointestinal fistula. We hypothesized that (1) DCL incidence would vary between institutions; (2) mortality rates would vary with DCL rates; (3) standard DCL criteria of pH, international normalized ratio, temperature and major intra-abdominal vascular injury would not adequately capture all patients. METHODS: Trauma patients at 12 Level 1 North American trauma centers were randomized based on transfusion ratios as described in the Pragmatic, Randomized Optimal Platelet and Plasma Ratios trial. We analyzed outcomes after emergent laparotomy using a mixed-effects logistic model comparing DCL versus definitive surgical management with random effect for study site. Primary outcomes were 24-hour and 30-day mortality. RESULTS: Three hundred twenty-nine patients underwent emergent laparotomy: 213 (65%) DCL and 116 (35%) definitive surgical management. DCL rates varied between institutions (33-83%), (p = 0.002). Median Injury Severity Score (ISS) was higher in the DCL group, 29 (interquartile range, 13-34) versus 21 (interquartile range, 22-41) (p < 0.001). Twenty-four-hour mortality was 19% with DCL versus 4% (p < 0.001); 30-day mortality was 28% with DCL versus 19% (p < 0.001). In a mixed-effects model, ISS and major intra-abdominal vascular injury were correlates of DCL (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.02-1.07 and OR, 2.7; 95% CI, 1.4-5.2). DCL was not associated with 30-day mortality (OR, 2.33; 95% CI, 0.97-5.60). Correlates included ISS (OR, 1.06; 95% CI, 1.02-1.09), PRBCs in 24 hours (OR, 1.10; 95% CI, 1.03-1.18), and age (OR, 1.04; 95% CI, 1.01-1.06). No significant mortality difference was detected between institutions (p = 0.63). Sepsis and VAP occurred more frequently with DCL (p < 0.05). Eighty percent (135/213) of DCL patients met standard criteria. CONCLUSION: Although DCL utilization varied significantly between institutions, there was no significant mortality difference between centers. This finding suggests tempering DCL use may not decrease mortality, but could decrease related complications. LEVEL OF EVIDENCE: Therapeutic study, level III.

Plasma Transfusion: History, Current Realities, and Novel Improvements.

Traumatic hemorrhage is the leading cause of preventable death after trauma. Early transfusion of plasma and balanced transfusion have been shown to optimize survival, mitigate the acute coagulopathy of trauma, and restore the endothelial glycocalyx. There are a myriad of plasma formulations available worldwide, including fresh frozen plasma, thawed plasma, liquid plasma, plasma frozen within 24 h, and lyophilized plasma (LP). Significant equipoise exists in the literature regarding the optimal plasma formulation. LP is a freeze-dried formulation that was originally developed in the 1930s and used by the American and British military in World War II. It was subsequently discontinued due to risk of disease transmission from pooled donors. Recently, there has been a significant amount of research focusing on optimizing reconstitution of LP. Findings show that sterile water buffered with ascorbic acid results in decreased blood loss with suppression of systemic inflammation. We are now beginning to realize the creation of a plasma-derived formulation that rapidly produces the associated benefits without logistical or safety constraints. This review will highlight the history of plasma, detail the various types of plasma formulations currently available, their pathophysiological effects, impacts of storage on coagulation factors in vitro and in vivo, novel concepts, and future directions.

A statewide teleradiology system reduces radiation exposure and charges in transferred trauma patients.

BACKGROUND: Trauma transfer patients routinely undergo repeat imaging because of inefficiencies within the radiology system. In 2009, the virtual private network (VPN) telemedicine system was adopted throughout Oregon allowing virtual image transfer between hospitals. The startup cost was a nominal $3,000 per hospital. METHODS: A retrospective review from 2007 to 2012 included 400 randomly selected adult trauma transfer patients based on a power analysis (200 pre/200 post). The primary outcome evaluated was reduction in repeat computed tomography (CT) scans. Secondary outcomes included cost savings, emergency department (ED) length of stay (LOS), and spared radiation. All data were analyzed using Mann-Whitney U and chi-square tests. P less than .05 indicated significance. Spared radiation was calculated as a weighted average per body region, and savings was calculated using charges obtained from Oregon Health and Science University radiology current procedural terminology codes. RESULTS: Four-hundred patients were included. Injury Severity Score, age, ED and overall LOS, mortality, trauma type, and gender were not statistically different between groups. The percentage of patients with repeat CT scans decreased after VPN implementation: CT abdomen (13.2% vs 2.8%, P < .01) and cervical spine (34.4% vs 18.2%, P < .01). Post-VPN, the total charges saved in 2012 for trauma transfer patients was $333,500, whereas the average radiation dose spared per person was 1.8 mSV. Length of stay in the ED for patients with Injury Severity Score less than 15 transferring to the ICU was decreased (P < .05). CONCLUSIONS: Implementation of a statewide teleradiology network resulted in fewer total repeat CT scans, significant savings, decrease in radiation exposure, and decreased LOS in the ED for patients with less complex injuries. The potential for health care savings by widespread adoption of a VPN is significant.

Damage-control resuscitation and emergency laparotomy: Findings from the PROPPR study.

BACKGROUND: The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial has demonstrated that damage-control resuscitation, a massive transfusion strategy targeting a balanced delivery of plasma-platelet-red blood cell in a ratio of 1:1:1, results in improved survival at 3 hours and a reduction in deaths caused by exsanguination in the first 24 hours compared with a 1:1:2 ratio. In light of these findings, we hypothesized that patients receiving 1:1:1 ratio would have improved survival after emergency laparotomy. METHODS: Severely injured patients predicted to receive a massive transfusion admitted to 12 Level I North American trauma centers were randomized to 1:1:1 versus 1:1:2 as described in the PROPPR trial. From these patients, the subset that underwent an emergency laparotomy, defined previously in the literature as laparotomy within 90 minutes of arrival, were identified. We compared rates and timing of emergency laparotomy as well as postsurgical survival at 24 hours and 30 days. RESULTS: Of the 680 enrolled patients, 613 underwent a surgical procedure, 397 underwent a laparotomy, and 346 underwent an emergency laparotomy. The percentages of patients undergoing emergency laparotomy were 51.5% (174 of 338) and 50.3% (172 of 342) for 1:1:1 and 1:1:2, respectively (p = 0.20). Median time to laparotomy was 28 minutes in both treatment groups. Among patients undergoing an emergency laparotomy, the proportions of patients surviving to 24 hours and 30 days were similar between treatment arms; 24-hour survival was 86.8% (151 of 174) for 1:1:1 and 83.1% (143 of 172) for 1:1:2 (p = 0.29), and 30-day survival was 79.3% (138 of 174) for 1:1:1 and 75.0% (129 of 172) for 1:1:2 (p = 0.30). CONCLUSION: We found no evidence that resuscitation strategy affects whether a patient requires an emergency laparotomy, time to laparotomy, or subsequent survival. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Recipient graft failure or death impact on living kidney donor quality of life based on the living organ donor network database.

BACKGROUND AND PURPOSE: There is a paucity of prospective long-term data on living kidney donor (LKD) quality of life (QoL). The Living Organ Donor Network (LODN) database follows donors longitudinally and cross-references with United Network for Organ Sharing (UNOS) data to assess factors that affect donor QoL. PATIENTS AND METHODS: The Short Form (SF)-36 was sent to donors at 6 months and yearly thereafter. Recipient outcomes were determined from the UNOS database. Of 2219 donors, 1030 returned ≥ 1 QoL survey in the first year. Seven-hundred and thirty-one donors returned at least two surveys with 51 associated with a nonfunctioning graft and 38 with recipient death. RESULTS: Initial QoL scores were not different between donors whose recipients were alive with graft function, and those whose recipients died (88.9 vs 89.2, P = 0.87). For donors whose recipient died, QoL in the year after recipient death averaged 6 points lower than the initial QoL (88.9 vs 82.9, P = 0.01). Thirty-one donors returned surveys an average of 4.1 years after their recipient's death. Final QoL score increased by 2.5 points, no longer significantly lower than the initial QoL (85.4 vs 88.9, P = 0.16). Thirty-eight donors returned surveys in the year after their recipient's graft failure and their QoL decreased by 5.6 points on average (86.9 vs 81.2, P = 0.07). Twenty-eight of these donors returned future surveys and final QoL was unchanged (81.2 vs 81.2, P = 0.99). CONCLUSIONS: Donor QoL declines after recipient death but recovers with time. Graft failure resulted in decreased QoL without recovery. The LODN database identifies factors affecting LKD QoL and provides a model for a national registry.
