RESUMO
BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a rescue procedure used for cardiac and pulmonary dysfunction. Patients on ECMO often require blood transfusions to maintain oxygen delivery and recover from bleeding complications. Goals of the current study were to determine transfusion requirements while on ECMO, and incidence and transfusion requirements for bleeding complications. METHODS: Packed red blood cell (PRBC) transfusions and bleeding complications were identified by retrospective chart review of patients on ECMO from 2010 to 2018 at our institution. Patients were categorized into those who did not bleed (group A) and those who bled (group B). Incidence, sites of bleed, and transfusion requirement for each bleeding were analyzed. RESULTS: Among 217 patients including veno-arterial (VA) (n = 148) and veno-venous (VV) (n = 69) ECMO, we identified 62 patients without bleeding complications (group A) and 155 patients with bleeding complications (group B). In group A, transfusion requirement was 0.6 PRBC/day for VA-ECMO (n = 42) and 0.2 PRBC/day for VV-ECMO (n = 20) (p = 0.0015). In group B, number of PRBC given per event per day for bleeding complications during ECMO was mediastinal/thoracic bleed (83 events, 4.7 PRBC/event/day), gastrointestinal bleed (59 events, 4.8 PRBC/event/day), cannulation site bleed (88 events, 3.6 PRBC/event/day), and nasopharyngeal bleed (103 events, 2.8 PRBC/event/day). Thirty-day hospital mortality rate was co-related to transfusion requirement (area under ROC curve: 0.70). CONCLUSION: Patients without clinical bleeding still required transfusion, with higher rates observed with VA- than VV-ECMO. Transfusion requirements dramatically increased when patients developed various bleeding complications and had a significant impact on 30-day mortality rate.

OBJECTIVE: Upper hemisternotomy (UHS) for supracoronary ascending aorta replacement (scAAR) with concomitant aortic valve replacement (AVR) results in less trauma and potentially faster convalescence compared with full sternotomy (FS). Direct head-to-head studies are lacking. We compared a group of UHS patients with a matched group of FS patients undergoing scAAR and AVR. METHODS: There were 198 patients who underwent scAAR and AVR procedures by a single surgeon between 1999 and 2020. After matching 6 preoperative characteristics, there were 50 UHS and 50 FS patients. Patients who required acute type A aortic dissection repair, reoperations, concomitant procedures, or hypothermic circulatory arrest were excluded. RESULTS: In the matched sample, the hospital mortality rate was 1% (1 of 100). The median cardiopulmonary bypass time was 150 (interquartile range [IQR], 131 to 172) min and 164.5 (IQR, 138 to 190) min, respectively, for the UHS and FS groups (P = 0.08). The median aortic cross-clamp time was 121 (IQR, 107 to 139) min during UHS and 131 (IQR, 115 to 159) min during FS (P = 0.05). The median ventilation time was 7 (IQR, 3 to 14) h versus 17 (IQR, 10 to 24) h, respectively, after UHS and FS (P = 0.005). The median hospital length of stay was 7 (IQR, 6 to 9) days after UHS and 8 (IQR, 7 to 11) days after FS (P = 0.05). CONCLUSIONS: The low morbidity and mortality support the wider use of UHS for scAAR and AVR in appropriately selected patients. Larger studies are needed to confirm these initial findings.

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.

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.
RESUMO
Robotic minimally invasive esophagectomy can be safely performed by adhering to key technical principles. Careful development of the gastric conduit with attention to blood supply and conduit orientation is critical. During thoracic dissection, capnothorax can distort the proximity of key mediastinal structures. In particular, care must be taken to avoid damage to the left mainstem bronchus during subcarinal nodal dissection. Robotic approach allows for an oncologically sound procedure and early mobilization of patients postoperatively, thus optimizing short and long-term outcomes.

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.

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.

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.

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.

Objectives: Although sublobar resections have gained traction, wedge resections vary widely in quality. We seek to characterize the demographic and facility-level variables associated with high-quality wedge resections. Methods: The National Cancer Database was queried from 2010 to 2018. Patients with T1/T2 N0 M0 non-small cell lung cancer 2 cm or less who underwent wedge resection without neoadjuvant therapy were included. A wedge resection with no nodes sampled or with positive margins was categorized as a low-quality wedge. A wedge resection with 4 or more nodes sampled and negative margins was categorized as a high-quality wedge. Facility-specific variables were investigated via quartile analysis based on the overall volume and proportion of high-quality wedge or low-quality wedge resections performed. Results: A total of 21,742 patients met inclusion criteria, 6390 (29.4%) of whom received a high-quality wedge resection. Factors associated with high-quality wedge resection included treatment at an academic center (3005 [47.0%] vs low-quality wedge 6279 [40.9%]; P < .001). The 30- and 90-day survivals were similar, but patients who received a high-quality wedge resection had improved 5-year survival (4902 [76.7%] vs 10,548 [68.7%]; P < .001). Facilities in the top quartile by volume of high-quality wedge resections performed 69% (4409) of all high-quality wedge resections, and facilities in the top quartile for low-quality wedge resections performed 67.6% (10,378) of all low-quality wedge resections. A total of 113 facilities were in the top quartile by volume for both high-quality wedge and low-quality wedge resections. Conclusions: High-quality wedge resections are associated with improved 5-year survival when compared with low-quality wedge resections. By volume, high-quality wedge and low-quality wedge resections cluster to a minority of facilities, many of which overlap. There is discordance between best practice guidelines and current practice patterns that warrants additional study.
RESUMO
Jejunostomy tubes are frequently placed at time of esophagectomy. The purpose of this study is to evaluate cessation of routine j-tube placement on postoperative body mass index (BMI), return to the emergency room, and time until adjuvant therapy. We performed a retrospective review of an institutional database for consecutive patients undergoing minimally invasive Ivor Lewis Esophagectomy from 2014-2021 (after January 2019, routine j-tube placement was abandoned). Data was analyzed using Pearson's Chi-squared tests and Student's t test with 2-sided significance level of P < 0.05. In total,179 patients were included, 95 underwent j-tube placement and 84 did not. Cohorts had comparable baseline BMI's (no j-tube: 30.48 vs j-tube: 28.64, P = 0.06) and anastomotic leak rates (2.4% vs 4.2%, P = 0.5). Patients with no jejunostomy tubes were more likely to receive total parenteral nutrition (14.3% vs 5.3%, P < 0.05), but were no more likely to require total parenteral nutrition at discharge and had comparable durations of TPN requirement (7 days vs 12 days, P = 0.53). There was no difference in mean BMI reduction at 2 weeks (2.54 vs 2.09, P = 0.49) and 3-6 months postoperatively (6.11 vs 4.45 P = 0.15). There was no difference in return to the emergency room (8.3% vs 8.4%, P = 0.98) or readmissions (13.1% vs 11.6%, P = 0.76). There was a no difference in mean time to adjuvant therapy (83.5 days vs 72.6 days, P = 0.67). At esophagectomy centers with low anastomotic leak rates, cessation of routine j-tube placement at time of minimally esophagectomy can be undertaken without increasing risk of readmission, time until initiation of adjuvant therapy, or significantly impacting postoperative BMI loss.
RESUMO
BACKGROUND: Segmental resection continues to gain favor in the treatment of early-stage non-small cell lung cancer, but there is limited data on outcomes as related to facility volume. The purpose of this study is to better define the relationship between segmentectomy outcomes, survival, and facility volume. METHODS: A retrospective cohort analysis was completed using the National Cancer Database. Patients with stage I disease undergoing segmentectomy 2004 to 2015 were included. Facility volume was determined per year; facilities performing higher than the median number of segmental resections were deemed high-volume and retained that classification for the remainder of the study. Propensity-score matching was used to compare 5-year survival and outcomes. RESULTS: Six hundred eighty-one centers performing 2481 segmentectomies were included. High-volume centers had higher utilization of minimally invasive approaches and lower conversion rates. There was no difference in readmission or 30-day mortality, but 90-day mortality differed between groups (1.2% vs. 2.6%, P = .03). High-volume centers were more likely to sample lymph nodes (88.5% vs. 80.7%, P < .01), and patients were less likely to have positives margins (1.3% vs. 2.7%, P = .03). Patients were no more likely to be upstaged based on facility volume (4.6% vs. 3.3%, P = .21). Overall, 5-year survival was better for patients treated at high-volume centers in the full cohort (69.5% vs. 66.4%, P = .014) but in propensity score-matched analysis this survival difference became non-significant (68.0% vs. 67.9% (P = .172). CONCLUSION: Segmentectomy performed at high-volume centers is associated with more frequent use of minimally invasive approach, more frequent negative margins, and improved 90-day survival.

Background: There is limited data on the adult repair of pectus excavatum (PE). Existing literature is largely limited to single institution experiences and suggests that adults undergoing modified Nuss repair may have worse outcomes than pediatric and adolescent patients. Using a representative national database, this analysis is the first to describe trends in demographics, outcomes, charges, and facility volume for adults undergoing modified Nuss procedure. Methods: Because of a coding change associated with ICD-10, a retrospective cohort analysis using the National Inpatient Sample (NIS) for patients 12 or older undergoing modified Nuss repair between 2016-2018 was possible. Pearson's χ2 and Student's t-tests were utilized to compare patient, clinical, and hospital characteristics. Complications were sub-classified into major and minor categories. Facilities performing greater than the mean number of operations were categorized as high-volume. Results: Of 360 patients, 79.2% were male. There was near gender parity for patients over 30 undergoing repair (55.2% male, 44.8% female). In all age cohorts, patients were predominantly Caucasian. Rates of any postoperative complication differed by age (12-17 years: 30.6%; 18-29 years: 45.2%; 30+ years: 62.1%; P<0.01); older patients had higher rates of all but two subclasses of complication. Age over 30 was associated with higher charges (12-17 years: $57,312; 18-29 years: $57,001; 30+ years: $67,014; P<0.01). High-volume centers operate on older patients, had shorter lengths of stay, and comparable charges to low-volume centers. Conclusions: Women comprise nearly half of patients undergoing modified Nuss repair after 30 years of age. There are significant differences in complication rates and charges when comparing patients by age. Patients undergoing repair at high-volume facilities benefitted from shorter lengths of stay.
RESUMO
PURPOSE: There remain profound race-related disparities in the treatment of non-small cell lung cancer (NSCLC). Deferral of operative management for early-stage disease is recognized as driver of this disparity. Black race has been associated with higher rates of surgical deferral. It remains unclear how race impacts likelihood of receiving radiation therapy after declining surgical management of NSCLC. PATIENTS AND METHODS: A retrospective cohort analysis was completed using data from the National Cancer Database (NCBD) for patients 18 and over with stage I NSCLC offered surgical resection from 2004 to 2015 (N = 89,462). Multivariable logistic regression identified predictors of surgical deferral and predictors for deferral of radiation after deferral of surgery. Kaplan-Meier survival analysis with log-rank tests and multivariable Cox proportional hazards regressions were performed. RESULTS: 87,293 (97.6%) patients underwent surgery, 2169 (2.4%) deferred. Patients who deferred had 2.1 times higher hazard ratio for mortality, (HR = 2.08, [1.97, 2.29], P < .001). Of those that deferred, 1250 (57.6%) received postdeferral radiation. Compared to White patients, Black patients had OR of 1.82 for deferring both surgery and radiation (aOR: 1.82, [1.31, 2.53], P < .001) and Asian and Pacific Island (API) patients had an OR of 2.67 (aOR: 2.67, [1.27, 4.64], P = .008). Other predictors of deferral of therapy included: Medicare or lack of insurance, and treatment at nonacademic medical centers. CONCLUSION: Insurance status and Black race, and API race are associated with deferring surgical therapy and radiation therapy for NSCLC. These findings are consistent with the large body of work showing worse outcomes for treatment of NSCLC in minority patients.

Blockchain technology and cryptocurrencies could remake global health financing and usher in an era global health equity and universal health coverage. We outline and provide examples for at least four important ways in which this potential disruption of traditional global health funding mechanisms could occur: universal access to financing through direct transactions without third parties; novel new multilateral financing mechanisms; increased security and reduced fraud and corruption; and the opportunity for open markets for healthcare data that drive discovery and innovation. We see these issues as a paramount to the delivery of healthcare worldwide and relevant for payers and providers of healthcare at state, national and global levels; for government and non-governmental organisations; and for global aid organisations, including the WHO, International Monetary Fund and World Bank Group.
