Individual- and neighborhood-level characteristics of lung cancer screening participants undergoing telemedicine shared decision making.

BACKGROUND: Although lung cancer screening (LCS) for high-risk individuals reduces lung cancer mortality in clinical trial settings, many questions remain about how to implement high-quality LCS in real-world programs. With the increasing use of telemedicine in healthcare, studies examining this approach in the context of LCS are urgently needed. We aimed to identify sociodemographic and other factors associated with screening completion among individuals undergoing telemedicine Shared Decision Making (SDM) for LCS. METHODS: This retrospective study examined patients who completed Shared Decision Making (SDM) via telemedicine between May 4, 2020 - March 18, 2021 in a centralized LCS program. Individuals were categorized into Complete Screening vs. Incomplete Screening subgroups based on the status of subsequent LDCT completion. A multi-level, multivariate model was constructed to identify factors associated with incomplete screening. RESULTS: Among individuals undergoing telemedicine SDM during the study period, 20.6% did not complete a LDCT scan. Bivariate analysis demonstrated that Black/African-American race, Medicaid insurance status, and new patient type were associated with greater odds of incomplete screening. On multi-level, multivariate analysis, individuals who were new patients undergoing baseline LDCT or resided in a census tract with a high level of socioeconomic deprivation had significantly higher odds of incomplete screening. Individuals with a greater level of education experienced lower odds of incomplete screening. CONCLUSIONS: Among high-risk individuals undergoing telemedicine SDM for LCS, predictors of incomplete screening included low education, high neighborhood-level deprivation, and new patient type. Future research should focus on testing implementation strategies to improve LDCT completion rates while leveraging telemedicine for high-quality LCS.

Extracorporeal life support and cardiopulmonary bypass for central airway surgery: A systematic review.

BACKGROUND: Major airway surgery can pose a complex problem to perioperative central airway management. Adjuncts to advanced ventilation strategies have included cardiopulmonary bypass, veno-arterial, or veno-venous extracorporeal life support. We performed a systematic review to assess the existing evidence utilizing these strategies. METHODS: An electronic search was conducted to identify studies written in English reporting the use of extracorporeal life support (ECLS) during central airway surgery. Thirty-six articles consisting of 78 patients were selected and patient-level data were analyzed. RESULTS: Median patient age was 47 [IQR: 34-53] and 59.0% (46/78) were male. Indications for surgery included central airway or mediastinal cancer in 57.7% (45/78), lesion or injury in 15.4% (12/78), and stenosis in 12.8% (10/78). Support was initiated pre-operatively in 9.9% (7/71) and at the time of induction in 55.3% (42/76). It was most commonly used at the time of tracheal resection/repair [93.2% (68/73)], intubation of the tracheal stump [94.4% (68/72)], and re-anastomosis [94.2% (65/69)]; 13.7% (10/73) patients were supported post-operatively. The most commonly performed surgery was tracheal repair or resection in 70.3% (52/74). Median hospital stay was 12 [8, 25] days and in-hospital mortality was 7.9% (6/76). There was no significant difference in survival between the three groups (p = .54). CONCLUSIONS: Extracorporeal membrane oxygenation offers versatility in timing, surgical approach, and ECLS runtime that makes it a viable addition to the surgical armamentarium for treating complex central airway pathologies.

Transitioning a Surgery Practice to Telehealth During COVID-19.

: The spread of COVID-19 has challenged practices across the United States to dramatically change inpatient and outpatient practices to focus on containing spread of the virus and accommodate the anticipated increase in volume of acute illness. Despite this transition, practices will need to continue to accommodate evaluation of newly diagnosed malignancies, routine postoperative visits, and acute postoperative issues. Building on an existing telemedicine framework, we aim to describe rapid transition in our outpatient care to a telehealth model in a general thoracic surgery practice during COVID-19.

Black patients referred to a lung cancer screening program experience lower rates of screening and longer time to follow-up.

BACKGROUND: Racial disparities are well-documented in preventive cancer care, but they have not been fully explored in the context of lung cancer screening. We sought to explore racial differences in lung cancer screening outcomes within a lung cancer screening program (LCSP) at our urban academic medical center including differences in baseline low-dose computed tomography (LDCT) results, time to follow-up, adherence, as well as return to annual screening after additional imaging, loss to follow-up, and cancer diagnoses in patients with positive baseline scans. METHODS: A historical cohort study of patients referred to our LCSP was conducted to extract demographic and clinical characteristics, smoking history, and lung cancer screening outcomes. RESULTS: After referral to the LCSP, blacks had significantly lower odds of receiving LDCT compared to whites, even while controlling for individual lung cancer risk factors and neighborhood-level factors. Blacks also demonstrated a trend toward delayed follow-up, decreased adherence, and loss to follow-up across all Lung-RADS categories. CONCLUSIONS: Overall, lung cancer screening annual adherence rates were low, regardless of race, highlighting the need for increased patient education and outreach. Furthermore, the disparities in race we identified encourage further research with the purpose of creating culturally competent and inclusive LCSPs.

Surgical management of growing teratoma syndrome: robotic-assisted thoracoscopic resection of mediastinal teratoma.

BACKGROUND: Growing teratoma syndrome is a rare condition defined by the presence of enlarging metastatic lesions on serial imaging that arise after or during systemic chemotherapy for nonseminomatous germ cell tumors. Lesions commonly occur in the retroperitoneum, mediastinum, or lung and are notoriously unresponsive to conventional chemoradiotherapy. METHODS: In this study, we present a dynamic case of a 26-year-old male, who had undergone surgical resection and systemic bleomycin treatment for a metastatic nonseminomatous germ cell tumor, and later developed recurrent masses in his posterior mediastinum seen on surveillance imaging. Tumor markers remained normal. These lesions were resected via a right robot-assisted thoracoscopic approach with the da Vinci Xi®. RESULTS: The operation was completed successfully with an unremarkable postoperative hospital course. The robotic-assisted right thoracoscopic approach allowed for a minimally invasive dissection with good visualization and minimal morbidity when compared to previous cases of surgically resected mediastinal teratomas. Final pathology demonstrated mature teratomatous elements within a setting of inflammation and necrosis. CONCLUSIONS: Robot-assisted thoracoscopic management of metastatic mediastinal lesions in the setting of this rare condition is safe and feasible.

A standardized comparison of peri-operative complications after minimally invasive esophagectomy: Ivor Lewis versus McKeown.

BACKGROUND: While our institutional approach to esophageal resection for cancer has traditionally favored a minimally invasive (MI) 3-hole, McKeown esophagectomy (MIE 3-hole) during the last five years several factors has determined a shift in our practice with an increasing number of minimally invasive Ivor Lewis (MIE IL) resections being performed. We compared peri-operative outcomes of the two procedures, hypothesizing that MIE IL would be less morbid in the peri-operative setting compared to MIE 3-hole. METHODS: Our institution's IRB-approved esophageal database was queried to identify all patients who underwent totally MI esophagectomy (MIE IL vs. MIE 3-hole) from June 2011 to May 2016. Patient demographics, preoperative and peri-operative data, as well as post-operative complications were compared between the two groups. Post-operative complications were analyzed using the Clavien-Dindo classification system. RESULTS: There were 110 patients who underwent totally MI esophagectomy (MIE IL n = 49 [45%], MIE 3-hole n = 61 [55%]). The majority of patients were men (n = 91, 83%) with a median age of 62.5 (range 31-83). Preoperative risk stratifiers such as ECOG score, ASA, and Charlson Comorbidity Index were not significantly different between groups. Anastomotic leak rate was 2.0% in the MIE IL group compared to 6.6% in the MIE 3-hole group (p = 0.379). The rate of serious (Clavien-Dindo 3, 4, or 5) post-operative complications was significantly less in the MIE IL group (34.7 vs. 59.0%, p = 0.013). Serious pulmonary complications were not significantly different (16.3 vs. 26.2%, p = 0.251) between the two groups. CONCLUSIONS: In this cohort, totally MIE IL showed significantly less severe peri-operative morbidity than MIE 3-hole, but similar rates of serious pulmonary complications and anastomotic leaks. These findings confirm the safety of minimally invasive Ivor Lewis esophagectomies for esophageal cancer when oncologically and clinically appropriate. Minimally invasive McKeown esophagectomy remains a satisfactory and appropriate option when clinically indicated.

Surgical Apgar score (SAS) predicts perioperative morbidity, mortality, and length of stay in patients undergoing esophagectomy at a high-volume center.

BACKGROUND: Esophagectomy carries considerable morbidity. Many studies have evaluated factors to predict patients at risk. This study aimed to determine whether the surgical Apgar score (SAS) predicts complications and length of stay (LOS) for patients undergoing esophagectomy. STUDY DESIGN: We evaluated 212 patients undergoing esophagectomy. Postoperative complications were graded using the Clavien-Dindo scale and the SAS was determined. Association of SAS with incidence of complications was evaluated using the Cochran-Armitage trend test between grouped SAS scores (0-2, 3-4, 5-6, 7-8, 9-10) and each of the outcomes. Correlation of SAS with LOS was evaluated using competing risks proportional hazards regression. RESULTS: The average patient age was 63.5 years (range 31-86), and the average blood loss was 284 mL (range 50-4000). The median LOS was 10 days. There was a significant association between SAS and grade 2 or higher (P = 0.0002) and grade 3 or higher (P < 0.0001) complications. The perioperative mortality rate was 5.2% (n = 11) with lower SAS being associated with greater mortality. LOS was also associated with SAS (P < 0.0001). CONCLUSIONS: We demonstrate that SAS is a significant predictor of complications and LOS for patients undergoing esophagectomy. SAS should be used to identify lower risk patients to prioritize use of critical care beds and hospital resources.

Association between surgical quality and long-term survival in lung cancer.

OBJECTIVES: There are significant variations in both perioperative and long-term outcomes after lung cancer resection. While perioperative outcomes are often used as comparative measures of quality, they are unreliable, and their association with long-term outcomes remain unclear. In this context, we evaluated whether historical perioperative mortality after lung cancer resection is associated with 5-year survival. PATIENTS AND METHODS: The National Cancer Database (NCDB) was queried to identify patients diagnosed with non-small cell lung cancer (NSCLC) in 2010-2016 who underwent surgical resection (n = 234200). Hospital-level reliability-adjusted 90-day mortality rate quartiles for 2010-2013 was used as the independent variable to analyze 5-year survival for patients diagnosed in 2014-2016 (n = 85396). RESULTS: There were 85,396 patients in the 2014-2016 cohort across 1,086 hospitals. Overall observed 90-day mortality rate was 3.2% (SD 17.6%) with 2.6% (SD 16.0%) for the historically best performing quartile vs. 3.9% (SD 19.4%) for the worst performing quartile (p < 0.0001). Patients who underwent resection at hospitals with the best historical mortality rate had significantly better 5-year survival across all stages compared to those treated at hospitals in the worst performing quartile in multivariate Cox regression analysis (all stages - HR 1.21 [95% CI 1.15-1.26]; stage I - HR 1.19 [95% CI 1.12-1.25]; stage II - HR 1.20 [95% CI 1.09-1.32]; stage III - HR 1.36 [95% CI 1.20-1.54]) and Kaplan-Meier survival estimates (all stages - p < 0.0001, stage I - p < 0.0001; stage II - p = 0.0004; stage III - p < 0.0001). CONCLUSION: With expanded lung cancer screening criteria and likely increase in early-stage detection, profiling performance is paramount to ensuring mortality benefits. We found that episodes surrounding surgical resection may be used to profile long-term outcomes that likely reflect quality across a broader context of care. Evaluating lung cancer care quality using perioperative outcomes may be useful in profiling provider performance and guiding value-based payment policies.

Access to Guideline Concordant Care for Node-Positive Non-Small Cell Lung Cancer in the United States.

BACKGROUND: This study sought to determine whether seeking care at multiple Commission on Cancer (CoC) hospitals is associated with different rates of receiving guideline-concordant care (GCC) among patients with non-small cell lung cancer (NSCLC). METHODS: The National Cancer Database was queried for the years 2004 to 2018 for patients with margin-negative pT1 to pT3 N1 to N2 M0 noncarcinoid NSCLC without neoadjuvant therapy. GCC was defined as chemotherapy for pN1 disease and as chemotherapy with or without radiation for pN2 disease. Patients who received care at >1 facility were examined separately. Factors previously associated with barriers to care were compared between groups. Kaplan-Meier analysis with log-rank tests analyzed 5-year overall survival (OS). Propensity score matching was performed to compare the effect sizes of race, insurance status, and income. RESULTS: In total 44,531 patients met inclusion criteria, 11,980 (26.9%) of whom sought care at >1 CoC institution. Among patients with pN1 disease, 5565 (76.7%) received GCC if they visited >1 facility vs 13,995 (68.5%) patients who sought care at 1 facility (P < .001). For patients with pN2 disease, 3991 (84.4%) received GCC if they visited >1 facility vs9369 (77.4%) patients receiving care at 1 facility (P < .001). Visiting >1 facility was associated with higher OS at 5 years (4784 [54.35%] vs 10,215 [45.62%]; P < .001). CONCLUSIONS: Visiting >1 CoC institution is associated with higher rates of GCC for individuals with pN1 to pN2 lung cancer. Patients who received care at >1 facility had higher OS at 5 years. Further study is warranted to identify factors associated with the ability of patients to seek care at multiple facilities.

Wedge Resection Outcomes: A Comparison of Video-Assisted and Robot-Assisted Wedge Resections.

BACKGROUND: Quality of oncologic resection for early-stage non-small cell lung cancer (NSCLC) may differ by surgical approach. Minimally invasive surgery has become the standard for surgical treatment of NSCLC. Our study compares quality of wedge resection by video-assisted thoracoscopic surgery (VATS) vs robotic video-assisted thoracoscopic surgery (RVATS). We hypothesized that RVATS would result in higher quality resections and improved patient outcomes. METHODS: A retrospective cohort analysis was completed using the National Cancer Database for patients with clinical stage 1 NSCLC with tumor size ≤2 cm who underwent a minimally invasive surgery wedge resection from 2010 to 2019. Wedge resections approached with RVATS were compared with VATS. A 1:1 propensity score matched analysis was performed. RESULTS: The cohort included 16,559 patients; 80.4% (13,406) received VATS and 18.9% (3153) received RVATS. Compared with RVATS, a VATS approach was associated with a lower likelihood of lymph nodes being examined (59.0% vs 75.2%; P < .001), fewer nodes dissected (median, 4 vs 5; P < .001), and less adjuvant systemic therapy administered (1.3% vs 2.2%; P < .001). Propensity score matching resulted in 2590 balanced pairs. Statistical significance was maintained for likelihood of lymph nodes examined, number of nodes dissected, and adjuvant systemic therapy administered. There was no significant difference in nodal upstaging after propensity score matching (3.7% vs 4.3%; P = .37). CONCLUSIONS: Compared with the VATS approach, wedge resections by RVATS for early-stage NSCLC were more likely to be associated with increased lymph nodes resected. These data may support increased use of RVATS for wedge resections.

Factors Associated With Margin Positivity After Lung Resection Surgery.

INTRODUCTION: The purpose of this study is to utilize a representative national sample to investigate the factors associated with margin positivity after attempted surgical resection. Given the changes in surgical approaches to lung cancer for the last 10 years, margin positivity and outcomes between robotic, video assisted thoracoscopic surgery (VATS) and open surgical resections may vary. METHODS: This retrospective cohort study utilized the National Cancer Database. Patients with non-small-cell lung cancer, 18 or older and who had a surgical lung resection between 2010 and 2019 were included. Demographic data, along with patient-level clinical variables were extracted. Patient-level outcome variables including 30-day, 90-day mortality and readmission rates were analyzed. Univariable and multivariable logistic regression was utilized to assess factors associated with margin positivity. RESULTS: A total of 226,884 patients were identified. Of the total cohort, 9229 had positive margins (4.2%). Patients with positive margins had statistically significant increased 30-day, 90-day mortality, as well as increased readmission rate. Older age, male sex, patients undergoing an open resection, patients who underwent a wedge resection, higher clinical stage, larger tumor size, squamous and adenosquamous histologies, and higher Charlson-Deyo Comorbidity Index were all associated with having a positive margin after resection. CONCLUSION: In conclusion, there was no difference in margin positivity when comparing robotic and VATS resection, however, open resection had increased rates of margin positivity. Increasing tumor size, clinical stage, squamous and adenosquamous histologies, male sex, and patients undergoing a wedge resection were all associated with increased rates of margin positivity.

Association Between Utilization of Services and Perioperative Outcomes for Lung Cancer Resection.

INTRODUCTION: Lung cancer resection has largely focused on perioperative outcomes (eg, mortality) to benchmark performance. While variations in perioperative outcomes and in utilization of services (eg, ambulatory procedures, hospitalization) have been independently demonstrated, there has been limited evaluation of associations between these outcomes. We evaluated the association between perioperative outcomes and utilization of services to evaluate provider performance across a broader context of care. PATIENTS AND METHODS: This was a retrospective cohort study of patients undergoing lung cancer resection in 2017 to 2019. We utilized hierarchical logistic regression models to determine risk- and reliability-adjusted mortality and risk-adjusted utilization of services, at the hospital-level. We then evaluated utilization of services across quartiles of perioperative mortality. RESULTS: A total of 15,168 patients across 297 hospitals underwent lung cancer resection. Mean risk- and reliability-adjusted 90-day mortality varied between 1.58% (95% CI, 1.54%-1.62%) and 2.74% (95% CI, 2.59%-2.90%) across quartiles. Risk-adjusted utilization of all ambulatory procedures was highest in the best performing (lowest mortality) quartile at 37.7% (95% CI, 33.6%-41.8%). Additionally, risk-adjusted inpatient utilization prior to and after surgery was lowest in the best performing quartile at 15% (95% CI, 13.7%-16.3%) and 19.3% (95% CI, 17.5%-21.0%), respectively. CONCLUSIONS: Hospitals with the lowest perioperative mortality demonstrated trends towards using more outpatient resources prior to surgery, but fewer inpatient services surrounding lung cancer resection. This correlation highlights the importance of incorporating utilization of services in addition to other metrics to profile the efficiency and effectiveness of centers performing lung cancer resection across a broader spectrum of care.

Surgical Outcomes in the National Lung Screening Trial Compared With Contemporary Practice.

BACKGROUND: The National Lung Screening Trial (NLST) established a role for lung cancer screening. Mortality benefits with screening are predicated on successful treatment with low surgical mortality. Given variations observed in perioperative outcomes after lung cancer resection, it remains unknown whether benefits observed in the NLST are generalizable to a broader population. We sought to determine whether NLST perioperative outcomes are reflective of contemporary practice in a national cohort. METHODS: We identified patients diagnosed with non-small cell lung cancer who underwent lung resection in the 2014 to 2015 National Cancer Database (NCDB) and the NLST. We compared demographic and cancer characteristics in both datasets. We used hierarchical logistic regression to compare 30-day and 90-day postoperative mortality across facilities in both datasets. RESULTS: In all, 65054 patients in NCDB and 1003 patients in the NLST treated across 1119 NCDB hospitals and 33 NLST hospitals were included. After risk and reliability adjustment, mean 30-day and 90-day mortality were significantly higher among NCDB hospitals (mean 30-day, 2.2 [95% confidence interval (CI), 2.2 to 2.2] vs 1.8 [95% CI, 1.8 to 1.8], P < .001; mean 90-day, 4.2 [95% CI, 4.2 to 4.3] vs 2.9 [95% CI, 2.9 to 2.9], P < .001). Variation in risk- and reliability-adjusted 30-day mortality (95% CI, 1.1% to 4.9%) and 90-day mortality (95% CI, 2.6% to 9.7%) was observed among NCDB hospitals. Adjusted mortality was similar among NLST facilities (30 days, 1.8% to 1.8%; 90 days, 2.9% to 2.9%). CONCLUSIONS: Risk- and reliability-adjusted postoperative mortality varies widely in a national cohort compared with outcomes observed in the NLST. Efforts to minimize this variation are needed to ensure that benefits of lung cancer screening are fully realized in the United States.

Impact of stereotactic body radiation therapy volume on surgical patient selection, short-term survival, and long-term survival in early-stage non-small cell lung cancer.

OBJECTIVES: Stereotactic body radiation therapy (SBRT) is increasingly used to treat non-small cell lung cancer. The purpose of this study is to analyze relationships between facility SBRT utilization and surgical patient selection and survival after surgery. METHODS: Data on patients with TI/T2N0M0 lesions and treatment facility characteristics were abstracted from the National Cancer Database, 2008 to 2017. Facilities were stratified using an SBRT/surgery ratio previously associated with short-term survival benefit for patients treated surgically, and by a previously identified surgical volume threshold. Multiple regression analyses, Cox proportional-hazard regressions, and Kaplan-Meier log rank test were employed. RESULTS: In total, 182,610 patients were included. Proportion of high SBRT:surgery ratio (≥17%) facilities increased from 118 (11.5%) to 558 (48.4%) over the study period. Patients undergoing surgery at high-SBRT facilities had comparable comorbidity scores and tumor sizes to those at low-SBRT facilities, and nonclinically significant differences in age, race, and insurance status. Among low-volume surgical facilities, treatment at a high SBRT-using facility was associated with decreased 30-day mortality (1.8% vs 1.4%, P < .001) and 90-day mortality (3.3% vs 2.6%, P < .001). At high-volume surgical facilities, no difference was observed. At 5 years, a survival advantage was identified for patients undergoing resection at facilities with high surgical volumes (hazard ratio, 0.91; confidence interval, 0.90-0.93 P < .001) but not at high SBRT-utilizing facilities. CONCLUSIONS: Differences in short-term survival following resection at facilities with high-SBRT utilization may be attributable to low surgical volume facilities. Patients treated at high volume surgical facilities do not demonstrate differences in short-term or long-term survival based on facility SBRT utilization.

Intraoperative Versus Preoperative Diagnosis of Lung Cancer: Differences in Treatments and Patient Outcomes.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is frequently diagnosed during surgical resection. It remains unclear if lack of preoperative tissue diagnosis influences likelihood of receipt of guideline-concordant care or postoperative outcomes. METHODS: A retrospective cohort analysis was completed utilizing the National Cancer Database for patients undergoing lung resection with clinical stage 1 NSCLC from 2004 to 2018. Diagnosis during resection was defined as zero days between diagnosis and definitive lung resection. Patients receiving neoadjuvant therapy were excluded. Subgroup analyses were completed by resection type, including wedge resection. RESULTS: The cohort included 91,328 patients, 33,517 diagnosed during definitive resection and 57,811 diagnosed preoperatively. For patients diagnosed preoperatively, median time from diagnosis to surgery was 42 days (interquartile range 28-63 days). Patients diagnosed intraoperatively had smaller median tumor size (1.7 cm vs. 2.5 cm, P < .01) and were more likely to undergo wedge resection (10,668 [31.8%] vs. 7,617 [13.2%], P < .01). Intraoperative diagnosis resulted in lower likelihood of nodal sampling (27,356 [81.9%] vs. 53,183 [92.4%], P < .01) and nodal upstaging (2,482 [9.7%] vs. 7701 [15.5%], P < .01). Amongst patients with intraoperative diagnoses, those treated via wedge resection were less likely to undergo lymph node sampling (5,515 [52.0%] vs. 5,606 [61.1%], P < .01). Amongst patients with positive lymph nodes, patients diagnosed intraoperatively were less likely to receive adjuvant therapy (1,677 [5.0%] vs. 5,669 [9.8%], P < .01). CONCLUSIONS: Preoperative tissue diagnosis of NSCLC is associated with more frequent lymph node harvest, increased rates of upstaging and receipt of adjuvant therapy. Preoperative workup may contribute to increased rates of guideline-concordant lung cancer care.

Hospital Utilization of Stereotactic Body Radiation Therapy and Rates of Surgical Refusal.

BACKGROUND: Increasingly, stereotactic body radiation therapy (SBRT) is used for patients unfit for or unwilling to undergo operation for early-stage non-small cell lung cancer. It remains unclear how SBRT utilization has influenced patient refusal of surgical resection. METHODS: A retrospective cohort analysis was completed using the National Cancer Database for patients with T1/T2 N0 M0 lesions from 2008 to 2017. Facilities were categorized into tertiles by SBRT/surgery ratio for each year of analysis. Propensity score matching was used to compare rates of surgical refusal and rates of postrefusal receipt of SBRT. Multivariable regression analysis was performed to evaluate effect size. RESULTS: The study included 129 901 patients; 63 048 were treated at low-tertile SBRT/surgery facilities, 41 674 at middle-tertile SBRT/surgery facilities, and 25 179 at high-tertile SBRT/surgery facilities. Patients refusing surgery at high SBRT/surgery facilities had fewer comorbid conditions and smaller tumors. Rates of SBRT after surgical refusal differed (low SBRT/surgery facilities, 17.2%; high SBRT/surgery facilities, 55.9%; P < .001). In a matched cohort of 76 636, surgical refusal differed (low SBRT/surgery facilities, 4.2%; high SBRT/surgery facilities, 6.0%; P < .001). On multivariable regression, treatment at a top-tertile SBRT/surgery facility was the largest risk factor for surgical refusal (odds ratio, 3.82 [3.53-4.13]; P < .001) and was most strongly associated with postrefusal receipt of SBRT (odds ratio, 6.11 [5.09-7.34]; P < .001). CONCLUSIONS: Patients treated at high SBRT-using facilities are more likely to refuse surgical resection and more likely to receive radiation therapy after surgical refusal. Further analysis is needed to better understand patient refusal of surgery in the setting of early-stage non-small cell lung cancer.

Defining risk factors for mortality after emergent hiatal hernia repair in the era of minimally invasive surgery.

BACKGROUND: Risk factors for mortality following emergent hiatal hernia (HH) repair in the era of minimally invasive surgery remain poorly defined. METHODS: Data was obtained from the National Inpatient Sample (NIS), National Readmissions Database, and National Emergency Department Sample for patients undergoing HH repair between 2010 and 2018. Univariate and multivariate logistic regression analyses reported with odds ratio (OR) and 95% confidence intervals (CI) were performed to identify factors associated mortality. RESULTS: Via the NIS, mortality rate was 2.2% (147 patients). Via the NEDS, the mortality rate was 3.6% (303 patients). On multivariate analysis, predictors of mortality included age (OR 1.05, CI: 1.04,1.07), male sex (OR 1.49, CI: 1.06,2.11), frailty (OR 2.49, CI: 1.65,3.75), open repair (OR 3.59, CI: 2.50,5.17), and congestive heart failure (OR 2.71, CI: 1.81,4.06). CONCLUSIONS: There are multiple risk factors for mortality after hiatal hernia repair. There is merit to a laparoscopic approach even in emergent settings.
