Abstract
BACKGROUND Venous thromboembolism is a leading cause of morbidity and mortality postoperatively. The current venous thromboembolism risk assessment tools have not been validated in gynecologic patients. Most patients undergoing hysterectomy for benign indications will receive mechanical or pharmacologic prophylaxis based on preoperative risk assessment. However, current guidelines do not incorporate newer data that indicate additional risk of venous thromboembolism with prolonged surgery times or mode of hysterectomy. OBJECTIVE This study aimed to determine the effect of length of surgery, or operative time, on the risk of venous thromboembolism within 30 days after hysterectomy and determine whether differences in the effect of operative time exist across age, body mass index, and surgical approach. STUDY DESIGN We performed a secondary analysis of prospectively collected surgical quality improvement data using the American College of Surgeons National Surgical Quality Improvement Program database, which contains demographic and perioperative information and 30-day postoperative outcomes from >500 hospitals, and targeted data files including procedure-specific risk factors and outcomes for a subset of hospitals. We analyzed patients undergoing abdominal, vaginal, or laparoscopic hysterectomy for benign conditions from 2014 to 2017, identified by the Current Procedural Terminology codes. We excluded patients with cancer, patients whose surgery was not performed by a gynecologist, patients who were not in the targeted files, and patients with missing operative time or with an operative time of <30 minutes. Patients were compared with respect to the incidence of venous thromboembolism and operative time, stratified by age, body mass index, and surgical approach. Multivariable logistic regression was performed; operative time was treated as a continuous, linear variable. RESULTS A total of 70,606 patients were included. The 30-day venous thromboembolism incidence was 0.4% (n=259). Patients with venous thromboembolism were more likely to be obese, have inpatient procedures, and had, on average, greater uterine weight. Hysterectomy approach was vaginal in 11,641 patients, laparoscopic in 41,557 patients, and abdominal in 17,408 patients. After adjustment, for each 60-minute increase in operative time, there was a 35% increase in the odds of venous thromboembolism (adjusted odds ratio, 1.35; 95% confidence interval, 1.25-1.45). Stratified by surgical approach, the odds of venous thromboembolism per 60-minute increase in operative time was greatest among abdominal hysterectomy (adjusted odds ratio, 1.49; 95% confidence interval, 1.35-1.65) compared with laparoscopic hysterectomy (adjusted odds ratio, 1.20; 95% confidence interval, 1.05-1.38) and vaginal hysterectomy (adjusted odds ratio, 1.27; 95% confidence interval, 0.97-1.66) (P=.01). Increasing body mass index and increasing age did not modify the impact of operative time on venous thromboembolism incidence (P=.66 and P=.58, respectively). CONCLUSION Every 60-minute increase in operative time was independently associated with a 35% increased odds of venous thromboembolism within 30 days of hysterectomy, and this risk was cumulative. Minimally invasive hysterectomy had lower odds of venous thromboembolism than abdominal hysterectomy across all time points.

Abstract
INTRODUCTION Few studies have reported the long-term results of minimally invasive Heller myotomy (HM) for the treatment of achalasia. Herein, we detail our 17-year experience with HM for the treatment of achalasia from a tertiary referral center. METHODS All patients undergoing elective HM at our institution from 2000 to 2017 were identified within a prospective institutional database. These patients were sent mail and electronic surveys to capture their symptoms of dysphagia, chest pain, and regurgitation pre- and postoperatively and were asked to evaluate their postoperative gastrointestinal quality of life. Responses from adult patients who underwent minimally invasive Heller myotomy with partial posterior (i.e., Toupet) fundoplication (HM-TF) were analyzed. RESULTS 294 patients were eligible for study inclusion; 139 (47%) completed our survey. Median time from HM-TF to survey response was 5.6 years. A majority of patients reported improvement in their dysphagia (91%), chest pain (70%), and regurgitation (87%) symptoms. Patients who underwent HM-TF more than 5 years ago were most likely to report heartburn symptoms. One (1%) patient went on to require esophagectomy for ongoing dysphagia and one (1%) patient required revisional fundoplication for their heartburn symptoms. CONCLUSIONS Minimally invasive Heller myotomy and posterior partial fundoplication is a durable treatment for achalasia over the long term. Additional prospective and multi-institutional studies are needed to validate our results.

Abstract
Surgical health services researchers are increasingly utilizing observational data to assess associations between treatments and outcomes, especially since some procedures are unable to be evaluated through randomized controlled trials. However, the results of many of these studies may be affected by the presence of immortal-time bias, which exists when treatment does not occur on Day 0 of the study. This bias can result in researchers overestimating a treatment benefit, or even observe a treatment benefit when none exists. In this paper, we describe what immortal-time bias is, the challenges it presents, and how to recognize and address it using the real-world example of surgical resection of the primary tumor for stage IV breast cancer throughout. In our example, we guide researchers and illustrate how the early studies, which did not account for immortal-time bias, suggested a protective benefit of surgery, and how these results were supplanted by more recent studies through identifying and addressing immortal-time bias in their design and analyses.

Abstract
Importance Private practice and academic surgery careers vary significantly in their daily routine, compensation schemes, and definition of productivity. Data are needed regarding the practice characteristics and job satisfaction of these career paths for surgeons and trainees to make informed career decisions and to identify modifiable factors that may be associated with the health of the surgical workforce. Objective To obtain and compare the differences in practice characteristics and career satisfaction measures between academic and private practice surgeons. Design, Setting, and Participants In this cross-sectional survey performed from June 4 to August 1, 2018, an online survey accommodating smartphone, tablet, and desktop formats was distributed by email to 25 748 surgeons who were actively practicing fellows of the American College of Surgeons; had completed a general surgery residency or categorical fellowship in plastic, cardiothoracic, or vascular surgery; and had an active email address on file. Main Outcomes and Measures Demographic, training, and current practice characteristics were obtained, and satisfaction measures were measured on a 5-point Likert scale and compared by surgeon type. Nonresponse weights adjusted for respondent sex, age, and presence of subspecialty training between respondents and the total surveyed American College of Surgeons population. Results There were 3807 responses (15% response rate) from surgeons: 1735 academic surgeons (1390 men [80%]; median age, 53 years [interquartile range (IQR), 44-61 years]) and 1464 private practice surgeons (1276 men [87%]; median age, 56 years [IQR, 48-62 years]); 589 surgeons who reported being neither an academic surgeon nor a private practice surgeon and 19 surgeons who did not respond to questions on their practice type were excluded. Academic surgeons reported working a median of 59 hours weekly (IQR, 38-65 hours) compared with 57 hours weekly (IQR, 45-65 hours) for private practice surgeons. Academic surgeons reported more weekly hours performing nonclinical work than did private practice surgeons (24 hours [IQR, 14-38 hours] vs 9 hours [IQR, 4-17 hours]; P < .001). Academic surgeons were more likely than private practice surgeons to be satisfied with their career as a surgeon (1448 of 1706 [85%] vs 1109 of 1420 [78%]; P < .001) and their financial compensation (997 of 1703 [59%] vs 546 of 1416 [39%]; P < .001). Academic surgeons were less likely than private practice surgeons to feel that competition with other surgeons is a threat to financial security (341 of 1705 [20%] vs 559 of 1422 [39%]; P < .001) and less likely to feel that malpractice experience has decreased job satisfaction (534 of 1703 [31%] vs 686 of 1413 [49%]; P < .001). Conclusions and Relevance This study suggests that, although overall surgeon satisfaction was high, academic surgeons reported higher career satisfaction on several measures when compared with private practice surgeons. Advocacy for private practice surgeons is important to encourage career longevity and sustain US surgeon workforce needs.

Abstract
OBJECTIVE In 2008, integrated thoracic residency programs (IP) for cardiothoracic (CT) training were created in response to a decline in CT trainees. However, few studies have reported on trends in the CT training pathway since the inception of IPs. This manuscript examines the current trends related to the overall number of surgical trainees entering CT surgery training following the introduction of IPs into the National Resident Match Program (NRMP). DESIGN Main and specialty match data were gathered from NRMP annual reports between 2008 and 2018. Descriptive statistics were used to analyze program size, applications, and filled and unfilled positions for IPs and traditional CT residency programs. Pearson's correlation coefficient was used to determine associations between program variables. SETTING NRMP main and specialty match in 2008 to 2018. PARTICIPANTS Participants of the NRMP main and specialty match in 2008 to 2018. RESULTS IPs increased from 2 programs offering 3 positions in 2008 to 28 programs offering 36 positions in 2018. However, during the same time period, the number of available traditional CT residency positions have decreased by 29% (130 to 92). As the number of IPs increased, there was a significant decrease in the number of traditional CT residency positions (ρ = -0.95, p < 0.001). Although, the overall number of CT residency programs (traditional and IP) remained largely unchanged, the proportion of filled CT residency positions increased from 67.7% in 2008 up to 97.7% in 2018. CONCLUSION The IP training format has shown success in increasing the number of trainees entering into CT training programs. Consideration should be given to increasing the number of IP positions or increase interest in CT among general surgery residents to increase the number of CT surgery trainees with the goal of increasing the size of the future CT workforce.

Abstract
Importance Although fluoroquinolones are commonly prescribed antibiotics in the US, recent international studies have shown an increased risk of aortic aneurysm and dissection after fluoroquinolone use, leading to US Food and Drug Administration warnings limiting use for high-risk patients. It is unclear whether these data are true for the US population and who is truly high risk. Objective To assess aortic aneurysm and dissection risks in a heterogeneous US population after fluoroquinolone use. Design, Setting, and Participants Prescription fills for fluoroquinolones or a comparator antibiotic from 2005 to 2017 among commercially insured individuals aged 18 to 64 years were identified in this retrospective analysis of MarketScan health insurance claims. This cohort study included 27 827 254 US adults (47 596 545 antibiotic episodes), aged 18 to 64 years, with no known previous aortic aneurysm or dissection, no recent antibiotic exposure, and no recent hospitalization. Exposures Outpatient fill of an oral fluoroquinolone or comparator antibiotic (amoxicillin-clavulanate, azithromycin, cephalexin, clindamycin, and sulfamethoxazole-trimethoprim). Main Outcomes and Measures The 90-day incidence of aortic aneurysm and dissection. Inverse probability of treatment weighting in Cox regression was used to estimate the association between fluoroquinolone fill and 90-day aneurysm incidence. Interaction terms were used to assess the association of known risk factors (ie, sex, age, and comorbidities) with aneurysm after fluoroquinolone use. Data analysis was performed March 2019 to May 2020. Results Of 47 596 545 prescription fills, 9 053 961 (19%) were fluoroquinolones and 38 542 584 (81%) were comparator antibiotics. The median (interquartile range) age of adults with fluoroquinolone fills was 47 (36-57) years vs 43 (31-54) years with comparator antibiotic fills. Women comprised 61.3% of fluoroquinolone fills and 59.5% of comparator antibiotic fills. Before weighting, the 90-day incidence of newly diagnosed aneurysm was 7.5 cases per 10 000 fills (6752 of 9 053 961) after fluoroquinolones compared with 4.6 cases per 10 000 fills (17 627 of 38 542 584) after comparator antibiotics. After weighting for demographic characteristics and comorbidities, fluoroquinolone fills were associated with increased incidence of aneurysm formation (hazard ratio [HR], 1.20; 95% CI, 1.17-1.24). More specifically, compared with comparator antibiotics, fluoroquinolone fills were associated with increased 90-day incidence of abdominal aortic aneurysm (HR, 1.31; 95% CI, 1.25-1.37), iliac artery aneurysm (HR, 1.60; 95% CI, 1.33-1.91), and other abdominal aneurysm (HR, 1.58; 95% CI, 1.39-1.79), and adults were more likely to undergo aneurysm repair (HR, 1.88; 95% CI, 1.44-2.46). When stratified by age, all adults 35 years or older appeared at increased risk (18-34 years: HR, 0.99 [95% CI, 0.83-1.18]; 35-49 years: HR, 1.18 [95% CI, 1.09-1.28]; 50-64 years: HR, 1.24 [95% CI, 1.19-1.28]; P = .04). Conclusions and Relevance This study found that fluoroquinolones were associated with increased incidence of aortic aneurysm formation in US adults. This association was consistent across adults aged 35 years or older, sex, and comorbidities, suggesting fluoroquinolone use should be pursued with caution in all adults, not just in high-risk individuals.

Abstract
BACKGROUND Fatigue after thyroidectomy is common, but there is a paucity of data regarding its prevalence and duration. We hypothesized that total thyroidectomy (TT) patients would have more long-term fatigue than thyroid lobectomy (TL) patients. METHODS Statewide survey of thyroidectomy patients (2004-2017) was carried out. RESULTS 281 patients completed the survey. 216 respondents (77%) had TT and 65 (23%) had TL. Within one year of surgery, 172 (61%) respondents recalled being troubled by new fatigue all, most, or some of the time. Total thyroidectomy patients were more likely to report new fatigue (69% vs. 44%, aOR 2.72, 95% CI 1.44 to 5.18). Of patients (n = 172) reporting new fatigue, 67 (39%) reported at least moderate improvement. Nineteen (28%) saw improvement within 1 year, 35 (52%) saw improvement in 1-2 years, and 11 (16%) saw improvement after 2 years. CONCLUSION Long-term fatigue after TT can be debilitating, long-lasting, and less prevalent after TL.

Abstract
As transcatheter aortic valve implantation (TAVI) continues its rapid growth as a treatment approach for aortic stenosis, costs associated with TAVI, and its burden to healthcare systems will assume greater importance. Patients undergoing TAVI between January 2012 and November 2017 in the Nationwide Readmission Database were identified. Trends in cause-specific readmissions were assessed using Poisson regression. Thirty-day TAVI cost burden (cost of index TAVI hospitalization plus total 30-day readmissions cost) was adjusted to 2017 U.S. dollars and trended over year from 2012 to 2017. Overall, 47,255 TAVI were included and 30-day readmissions declined from 20% to 12% (p <0.0001). Most common causes of readmission (heart failure, infection/sepsis, gastrointestinal causes, and respiratory) declined as well, except arrhythmia/heart block which increased (1.0% to 1.4%, p <0.0001). Cost of TAVI hospitalization ($52,024 to $44,110, p <0.0001) and 30-day cost burden ($54,122 to $45,252, p <0.0001) declined. Whereas costs of an average readmission did not change ($9,734 to $10,068, p = 0.06), cost burden of readmissions (per every TAVI performed) declined ($4,061 to $1,883, p <0.0001), including reductions in each of the top 5 causes except arrhythmia/heart block ($171 to $263, p = 0.04). Index TAVI hospitalizations complicated by acute kidney injury, length of stay ≥5 days, low hospital procedural volume, and skilled nursing facility discharge were associated with increased odds of 30-day readmissions. In conclusion, the costs of index hospitalizations and 30-day cost burden for TAVI in the U.S. significantly declined from 2012 to 2017. However, readmissions due to arrhythmia/heart block and their associated costs increased. Continued strategies to prevent readmissions, especially those for conduction disturbances, are crucial in the efforts to optimize outcomes and costs with the ongoing expansion of TAVI.

Abstract
BACKGROUND The burden of amyloidosis among hospitalized patients is increasing over time. However, amyloidosis remains an underdiagnosed cause of heart failure (HF) hospitalization among older adults. OBJECTIVES We investigated the prevalence and prognostic implications of amyloidosis among patients hospitalized with HF. METHODS All hospitalizations for primary diagnosis of HF between January 1, 2010, and August 31, 2015, identified in the Nationwide Readmissions Database were categorized into those with and without a secondary diagnosis of amyloidosis. HF hospitalizations with amyloidosis were then matched in a 3:1 fashion to HF hospitalizations without amyloidosis using the year of admission, discharge quarter, age, sex, and Charlson comorbidity index. Primary outcomes were inpatient mortality and 30-day readmission. Multivariable logistic regression was used to estimate the association between HF with amyloidosis and clinical outcomes. RESULTS Of 1,593,360 HF hospitalizations that met inclusion criteria, 2,846 (0.18%) had HF with a secondary diagnosis of amyloidosis and were matched to 8,515 hospitalizations for HF without amyloidosis. Hospitalizations for HF with amyloidosis were associated with higher prevalence of kidney disease (56% vs. 45%), malignancy (20% vs. 4%), and higher inpatient mortality (6% vs. 3%) as compared with HF without amyloidosis. In adjusted analyses, HF with amyloidosis was associated with higher odds of in-hospital mortality (odds ratio: 1.46; 95% confidence interval [CI]: 1.17 to 1.82), 30-day readmission (odds ratio: 1.17; 95% CI: 1.05 to 1.31), and longer mean length of stay (least-squares mean difference: 1.46; 95% CI: 1.12 to 1.80). CONCLUSIONS In patients hospitalized with decompensated HF, presence of amyloidosis was associated with higher risk of inpatient mortality and 30-day readmission.

Abstract
BACKGROUND Inflammatory breast cancer (IBC) has historically been characterized by high rates of recurrence and poor survival; however, there have been significant improvements in systemic therapy. We sought to investigate modern treatment of IBC and define the yield and prognostic significance of axillary lymph nodes after neoadjuvant chemotherapy (NAC). METHODS Women with clinical stage T4d, N0-N3, M0 IBC from 2012 to 2016 in the National Cancer Database were included. Kaplan-Meier survival curves and Cox regression were used to assess mortality by receptor subtype and nodal status. RESULTS We identified 5265 patients; 37% hormone receptor (HR) +/HER2 - , 19% HR +/HER2 + , 18% HR -/HER2 + , and 26% triple-negative, and 5-year overall survival was 51.6%. Only 34% were treated according to guidelines with NAC, modified radical mastectomy, and adjuvant radiation. Pathologically positive lymph nodes (ypN +) after NAC varied by subtype and clinical nodal status (cN) ranging from 82% in cN + HR +/HER2 - patients to 19% in cN0 HR -/HER2 + patients. ypN + strongly correlated with survival in all subtypes with the most pronounced impact in HR +/HER2 + patients, with 90% 5-year overall survival in ypN0 versus 66% for ypN + (HR 4.29, 95% CI 1.58-11.70, p = 0.03). CONCLUSIONS Five-year survival in M0 IBC is 51.6%. Positive nodes after NAC varied by subtype and clinical N status but is sufficiently high and provided meaningful prognostication in all subtypes to support continued routine pathologic assessment. Future study is warranted to identify reliable, less morbid, methods of staging the axilla in IBC patients appropriate for deescalation of axillary surgery.

Abstract
Few studies examine outcomes by surgical approach in non-small-cell lung cancer (NSCLC) with N2 disease. We examined time trends in surgical approach and outcomes among patients undergoing minimally invasive (MIS, robotic and video-assisted thoracoscopic surgery [VATS]) vs open lobectomy in this patient population. We performed a retrospective analysis of patients from the National Cancer Database diagnosed with clinical Stage IIIA-N2 NSCLC from 2010 to 2016. We examined the yearly proportion of MIS vs open resections. Multivariable regression was used to assess the association of surgical approach with length of stay, unplanned readmissions, 30-day and 90-day mortality. Multivariable Cox proportional hazards modeling was used to assess the association of surgical approach with 5-year overall mortality. We identified 5741 patients who underwent lobectomy for Stage IIIA-N2 NSCLC (459 robotic, 1403 VATS, 3879 open). From 2010 to 2016, the proportion of minimally invasive procedures increased from 20% to 45%. MIS patients, on average, stayed 1 day less in the hospital (95% confidence interval [CI] 0.7, 1.5) and had lower odds of 90-day (odds ratio [OR] 0.74; 95% CI 0.54, 0.99) and 5-year mortality (OR 0.82; 95% CI 0.75, 0.91), compared to open resections. There was no difference in odds of readmission by surgical approach (OR 0.97; 95% CI 0.71, 1.33). Among MIS procedures, robotic resections had lower odds of 90-day mortality (OR 0.42; 95% CI 0.18, 0.97) than VATS. Among patients undergoing lobectomy for locally advanced N2 NSCLC robotic and VATS techniques appear safe and effective compared to open surgery and may offer short- and long-term advantages.

Ann Surg Oncol 2020; 27:4853-4860. [PMID: 32918178 DOI: 10.1245/s10434-020-08945-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 07/14/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Elderly women (≥ 70 years old) form a significant proportion of patients affected by breast cancer (BC); however, the treatment decisions for this patient population are complicated, owing to the presence of comorbidities, limited life expectancy, reduced tolerability of therapy, and limited enrollment in clinical trials. A growing body of evidence suggests equivalent outcomes in elderly patients with hormone receptor-positive early-stage breast cancer receiving primary endocrine therapy only or surgery with subsequent endocrine therapy. Whether these results are reproduced in the larger BC population outside of a clinical trial currently remains unclear. PATIENTS AND METHODS Women ≥ 70 years old diagnosed with early-stage invasive breast cancer between January 2008 and December 2013 with tumor size T1 or T2, minimal nodal involvement (N0 and N1), and estrogen and/or progesterone receptor positivity who started endocrine therapy within a year of diagnosis were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked datasets. Endocrine therapy was identified using outpatient prescription fills for anastrozole, exemestane, fulvestrant, letrozole, raloxifene, tamoxifen, and toremifene; the first fill date was used as the treatment initiation date. Surgical intervention included either breast-conserving surgery or mastectomy. Women who received chemotherapy were excluded. Trends in the use of primary endocrine therapy only were assessed using Poisson regression. Multivariable Cox proportional hazard regression was used to estimate the association between undergoing surgery within a year of diagnosis and 5-year all-cause mortality, after adjusting for patient demographics, comorbidities, and clinical cancer characteristics. Similar methods were used to assess 5-year cancer-specific mortality, where noncancer mortality was treated as a competing risk. RESULTS Overall, 8784 women were included in the analysis: 8006 (91%) received surgery with endocrine therapy and 778 (9%) received primary endocrine therapy alone. The proportion of women not receiving surgery remained consistent between 2008 and 2013 (p = 0.10). The 5-year mortality was 11% (n = 619), and 19% of all deaths were due to cancer causes (n = 117). After adjustment, 5-year mortality was lower among women undergoing surgery (HR 0.59, 95% CI 0.47-0.74, p < 0.0001). Similar results were found when looking at 5-year cancer-specific mortality (HR 0.52, 95% CI 0.30-0.90, p < 0.0001). CONCLUSIONS Elderly breast cancer patients with early-stage hormone-receptor-positive disease receiving primary surgical intervention plus endocrine therapy may have significantly improved survival than those receiving primary endocrine therapy alone. This study suggests the importance of surgical intervention for elderly breast cancer patients and warrants further investigation and comprehensive geriatric assessment to identify subsets of elderly breast cancer patients who may benefit significantly from surgical intervention.

Abstract
BACKGROUND Merkel cell carcinoma (MCC) is a rare and aggressive form of skin cancer. It is an immunogenic tumor as evident by its association with Polyomavirus, immunotherapy response, and increased prevalence in the immunosuppressed population. OBJECTIVE We sought to evaluate the impact of known clinicopathological determinants and immunosuppression on the risk of recurrence and mortality of MCC patients. METHODS A retrospective, observational cohort study of patients diagnosed and/or treated with MCC at two tertiary academic institutions. We compared clinicopathological determinants, treatment modalities, and immunosuppression status on clinical outcomes of recurrence, disease-specific survival, and overall survival. RESULTS We evaluated 90 patients within our study and 34% had a cancer recurrence during follow-up. Patients with recurrence were significantly more likely to be immunosuppressed (32% vs 5%; P = .001). Estimated 5-year recurrence was 43%, and immunosuppressed patients were significantly more likely to recur (Hazard ratio [HR] 3.67 [1.80-7.51]; P < .0001). Immunosuppressed patients had significantly elevated cancer-specific mortality (HR 6.11[1.61-23.26]; P = .008). LIMITATIONS Retrospective review with a prolonged observation period and changing treatment modalities. CONCLUSION Immunocompromised patients had a threefold increased incidence of 5-year mortality and over twofold increased incidence of any recurrence as non-immunocompromised patients. Patients' immunosuppressive status should be considered when making decisions regarding treatment, surveillance, and prognostication.

Abstract
Alcohol and illicit drug use are common among burn-injured patients. Urine toxicology and alcohol screens are a part of our admission order sets and automatically ordered for all adult patients. Our objective was to determine the impact of bias in screening compliance and compare those results to patients who test positive. All adult patients admitted between January 1st, 2014 and December 31st, 2018 were eligible for inclusion. Multivariable logistic regression was used to identify potential predictors for compliance in obtaining samples for screens, and patient characteristics associated with testing positive. Four thousand nine hundred ninety-eight patients were included in the study. The biggest predictors for compliance in obtaining samples for screens were inhalation injury, intensive care unit stay, length of stay, burn size, and current smoking status. No differences in compliance with screens were seen across age, race, or ethnicity. Current smokers and patients with a history of major psychiatric illness were more likely to test positive for alcohol and illicit drugs. Non-Hispanic Black patients were more likely to test positive for illicit drugs. Male sex and pre-existing psychiatric conditions were significant predictors for compliance for alcohol screens, and, positive tests. Implicit bias based on age, race, or ethnicity played no predictive role in compliance for either screen, however, non-Hispanic Blacks were more likely to test positive for illicit drugs. More studies are needed to understand the effect of selection bias related to sample collection, and the significance of positive test results.

Abstract
BACKGROUND Hypertension (HTN) is a treatable and preventable risk factor for cardiovascular disease that is often overlooked in young adults. As a result, young patients with HTN may enter the health care system as a trauma without a preexisting diagnosis. The potential impact of HTN (diagnosed and undiagnosed) on trauma outcomes is not known. MATERIALS AND METHODS Patients aged 18-39 y from the 2013-2017 North Carolina Trauma Registry were included. Patients were stratified as having no HTN, previously diagnosed HTN (PD-HTN), or newly diagnosed HTN (ND-HTN) during a trauma admission. Multivariable logistic and linear regression compared inpatient outcomes between patients with and without HTN, as well as ND-HTN and PD-HTN. RESULTS Six percent of trauma patients were diagnosed with HTN (n = 1906; 14% ND-HTN). Those with HTN were more likely to have an inpatient complication (odds ratio [OR]: 1.65, 95% confidence interval [CI]: 1.32-2.07) and intensive care unit stay (OR: 1.28, 95% CI: 1.12-1.46) compared with patients without HTN. Compared with PD-HTN, those with ND-HTN were more likely to present with extreme injury. In addition, patients with ND-HTN had higher odds of inpatient complications (OR: 1.95, 95% CI: 1.18-3.22) and 30-d readmission (OR: 2.00, 95% CI: 0.95-4.20) after accounting for demographics and injury severity. CONCLUSIONS More than 10% of young adult trauma patients with HTN are not diagnosed before admission. HTN appears to have a detrimental impact on patient outcomes, with newly diagnosed patients having the worst outcomes. Trauma may serve as an opportunity for the diagnosis and treatment of HTN in young adults. Future studies should assess the impact of intervention on trauma outcomes.

Abstract
BACKGROUND In women with clinically node-negative breast cancer, sentinel lymph node biopsy is the first step in axillary staging. A randomized trial published in 2013 concluded that patients with sentinel lymph node micrometastases (N1mi) do not benefit from axillary lymph node dissection (ALND). We hypothesized that disparities exist in management of the axilla in node-negative patients. METHODS We included women aged >40 years with nonmetastatic, clinically node-negative breast cancer from 2014 to 2016 in the National Cancer Database. Women treated neoadjuvantly, with large tumors (cT4), or no tumor (cT0) were excluded. Multivariable logistic regression identified patient and facility characteristics associated with undergoing ALND as first axillary surgery and completion ALND in the setting of N1mi disease. RESULTS Of 273,951 patients, 22,898 (8%) underwent ALND first. These patients were more likely to be Hispanic (OR: 1.21, 95% CI: 1.10, 1.32), have Medicare (OR: 1.13, 95% CI: 1.03, 1.24), be uninsured (OR: 1.28, 95% CI: 1.08, 1.53), have lower educational attainment (OR: 1.24, 95% CI: 1.17, 1.32), be treated at a community hospital (OR: 1.62, 95% CI: 1.52, 1.74), or reside in the South (OR: 1.19, 95% CI: 1.12, 1.26). In the sentinel lymph node biopsy first group, 8,882 (4%) were classified as N1mi and 1,872 (21%) underwent subsequent ALND. These patients were more likely to be Hispanic (OR: 1.70, 95% CI: 1.19, 2.42) and have the lowest income (OR: 1.62, 95% CI: 1.15, 2.27). CONCLUSION Disparities persist in implementation of evidence-based management of the axilla in women with clinically node-negative breast cancer.

Abstract
574 Background: Omission of axillary surgery is appropriate in some patients with clinically node-negative (cN0), HR+ ESBC; however, there are no pre-operative tools to predict pathologic node positivity (pN+) in these women. We propose a clinically validated predictive model to inform treatment decisions regarding axillary evaluation. Methods: We constructed a cohort of adult women with ESBC (clinical T1/T2, N0, M0) diagnosed 2012-2016, who underwent lumpectomy or mastectomy and lymph node surgery without neoadjuvant therapy using the National Cancer Database breast cancer dataset. The dataset was non-randomly split into training (2012-2015) and testing (2016) for development and validation. Stepwise logistic regression was used to identify predictors of pathologic node positivity (pN0 vs pN+) in the training dataset. Potential predictors included: age, race, ethnicity, comorbidity score, histologic type, clinical T, ER positivity, PR positivity, HER2 positivity, and grade. Predictor variables required a bivariate p-value <0.30 to be entered into model, and an adjusted p-value <0.35 to stay in model. A partial score method was used to develop a lymph node prediction score (LNPS) by assigning a weighted value to each strong predictor variable (OR >1.5) and adding together the values for each included variable. LNPS was treated as a linear variable for prediction in validation dataset. Results: 423,068 women were included (2012-2015: 334,778; 2016: 88,290). Pathologic node positivity was 17% in 2012-2015 and 2016. All variables were included in the final stepwise model. Strong predictors were age, histologic type, clinical T, and grade. Scores ranged from 0-11. In the validation dataset, predicted pN+ by LNPS was very similar to actual pN+ (Table). A 1-point increase in LNPS was associated with a 3.3% increase in absolute risk of pN+. Conclusions: A novel lymph node prediction score can be used in HR+ cT1-T2 cN0 breast cancers to estimate the probability of pN+ and guide decisions regarding axillary surgical evaluation.
