Harmonized Outcome Measures for Use in Non-Small Cell Lung Cancer Patient Registries and Clinical Practice.

BACKGROUND: Lung cancer is the leading cause of cancer-related death in the United States and globally, and many questions exist about treatment options. Harmonizing data across registries and other data collection efforts would yield a robust data infrastructure to help address many research questions. The purpose of this project was to develop a minimum set of patient and clinician relevant harmonized outcome measures that can be collected in non-small cell lung cancer (NSCLC) patient registries and clinical practice. METHODS: Seventeen lung cancer registries and related efforts were identified and invited to submit outcome measures. Representatives from medical specialty societies, government agencies, health systems, health information technology groups, patient advocacy organizations, and industry formed a stakeholder panel to categorize the measures and harmonize definitions using the Agency for Healthcare Research and Quality's supported Outcome Measures Framework (OMF). RESULTS: The panel reviewed 66 outcome measures and identified a minimum set of 8 broadly relevant measures in the OMF categories of patient survival, clinical response, events of interest, and resource utilization. The panel harmonized definitions for the 8 measures through in-person and virtual meetings. The panel did not reach consensus on 1 specific validated instrument for capturing patient-reported outcomes. The minimum set of harmonized outcome measures is broadly relevant to clinicians and patients and feasible to capture across NSCLC disease stages and treatment pathways. A pilot test of these measures would be useful to document the burden and value of the measures for research and in clinical practice. CONCLUSIONS: By collecting the harmonized measures consistently, registries and other data collection systems could contribute to the development research infrastructure and learning health systems to support new research and improve patient outcomes.

The Adult Cardiac Anesthesiology Section of STS Adult Cardiac Surgery Database: 2020 Update on Quality and Outcomes.

The Society of Cardiovascular Anesthesiologists, in partnership with The Society of Thoracic Surgeons, has developed the Adult Cardiac Anesthesiology Section of the Adult Cardiac Surgery Database. The goal of this landmark collaboration is to advance clinical care, quality, and knowledge, and to demonstrate the value of cardiac anesthesiology in the perioperative care of cardiac surgical patients. Participation in the Adult Cardiac Anesthesiology Section has been optional since its inception in 2014 but has progressively increased. Opportunities for further growth and improvement remain. In this first update report on quality and outcomes of the Adult Cardiac Anesthesiology Section, we present an overview of the clinically significant anesthesia and surgical variables submitted between 2015 and 2018. Our review provides a summary of quality measures and outcomes related to the current practice of cardiothoracic anesthesiology. We also emphasize the potential for addressing high-impact research questions as data accumulate, with the overall goal of elucidating the influence of cardiac anesthesiology contributions to patient outcomes within the framework of the cardiac surgical team.

Health care disparities among octogenarians and nonagenarians with stage III lung cancer.

BACKGROUND: To the authors' knowledge, the practice patterns for patients aged more than 80 years with stage III non-small cell lung cancer (NSCLC) is not well known. The purpose of the current study was to investigate factors predictive of and the impact on overall survival (OS) after concurrent chemoradiation (CRT) among patients aged ≥80 years with American Joint Committee on Cancer stage III NSCLC in the National Cancer Data Base (NCDB). METHODS: In the NCDB, patients aged ≥80 years who were diagnosed with stage III NSCLC from 2004 to 2013 with complete treatment records were identified. Multivariable logistic regression and Cox proportional hazard models were generated and propensity score-matched analysis was used. RESULTS: A total of 12,641 patients met the entry criteria: 6018 (47.6%) had stage IIIA disease and 6623 (52.4%) had stage IIIB disease. The median age at the time of diagnosis was 83.0 years (range, 80-91 years). A total of 7921 patients (62.7%) received no therapy. Black race (odds ratio [OR], 1.23; 95% confidence interval [95% CI], 1.06-1.43) and living in a lower educated census tract of residence (OR, 1.20; 95% CI, 1.03-1.40) were found to be associated with not receiving care, whereas treatment at an academic center (OR, 0.80; 95% CI, 0.70-0.92) was associated with receiving cancer-directed therapy. Receipt of no treatment (hazard ratio [HR], 2.69; 95% CI, 2.57-2.82) or definitive radiation alone (HR, 1.15; 95% CI, 1.07-1.24) compared with CRT was associated with worse OS. On propensity score matching, not receiving CRT was found to be associated with worse OS (HR, 1.58; 95% CI, 1.44-1.72). CONCLUSIONS: In this NCDB analysis, approximately 62.7% of patients aged ≥80 years with stage III NSCLC received no cancer-directed care. Black race and living in a lower educated census tract were associated with not receiving cancer-directed care. OS was found to be improved in patients receiving CRT.

Minimally Invasive and Open Approaches to Mediastinal Nodal Assessment.

There is no consensus on mediastinal lymph node dissection versus sampling for early-stage lung cancer. There are also mixed data on the ability to remove an adequate number of lymph nodes by a minimally invasive approach. In this review, we discuss the difference between dissection and sampling, what circumstances dictate the use of one or the other during an anatomic pulmonary resection for lung cancer, and when it is appropriate to use minimally invasive versus open approaches in the assessment of mediastinal nodes.

Concurrent chemoradiotherapy with or without surgery for patients with resectable esophageal cancer: An analysis of the National Cancer Data Base.

BACKGROUND: Patients with resectable esophageal cancer (rEC) are managed with either concurrent chemoradiotherapy followed by surgery (CRSx) or concurrent chemoradiotherapy alone (cCR). To the authors' knowledge, there is insufficient evidence comparing the overall survival of patients treated with these 2 options. METHODS: The National Cancer Data Base was queried for rEC cases diagnosed from 2003 through 2011. Patients with previous cancers, cervical rEC, clinical stage T1N0 disease, or metastasis were excluded. cCR was defined as radiotherapy administered within 30 days of chemotherapy. CRSx was defined as cCR followed by esophagectomy within 90 days. Overall survival was compared using Kaplan-Meier methods, propensity score matching, and extended Cox proportional hazards models. RESULTS: Of the 11,122 eligible patients, 8091 (72.7%) received cCR and 3031 (27.3%) received CRSx. The odds of receiving CRSx were higher among patients with American Joint Committee on Cancer stage II disease (vs stage III), adenocarcinoma (vs squamous cell carcinoma), lesions of the lower one-third of the esophagus, private insurance, and those living >25 miles from the treating facility or in areas with a higher median income or a greater percentage of high school-educated residents. Patients aged >70 years, female patients, African-American patients, those with ≥2 comorbidities, or those treated at community programs were more likely to receive cCR. After propensity score matching, the median and 10-year survival rates were found to be significantly better with CRSx (32.5 months [95% confidence interval (95% CI), 29.6-34.8 months] and 23.8% months [95% CI, 20.0-27.9 months], respectively) compared with cCR (14.2 months [95% CI, 13.4-15.5 months] and 6.1% months [95% CI, 3.9-9.0 months], respectively). CONCLUSIONS: Data from the National Cancer Data Base support the inclusion of surgery after concurrent chemoradiotherapy for patients with locally advanced rEC.

Next-generation sequencing and clinical outcomes of patients with lung adenocarcinoma treated with stereotactic body radiotherapy.

BACKGROUND: Genetic aberrations are well characterized in lung adenocarcinomas (LACs) and clinical outcomes have been influenced by targeted therapies in the advanced setting. Stereotactic body radiotherapy (SBRT) is the standard-of-care therapy for patients with nonoperable, early-stage LAC, but to the authors' knowledge, no information is available regarding the impact of genomic changes in these patients. The current study sought to determine the frequency and clinical impact of genetic aberrations in this population. METHODS: Under an Institutional Review Board-approved protocol, the records of 242 consecutive patients with early-stage lung cancers were reviewed; inclusion criteria included LAC histology with an adequate tumor sample for the successful use of next-generation sequencing and fluorescence in situ hybridization testing. Univariate analysis was performed to identify factors associated with clinical outcomes. RESULTS: LAC samples from 98 of the 242 patients were reviewed (40.5%), of whom 45 patients (46.0%) had genetic testing. The following mutations were noted: KRAS in 20.0% of samples, BRAF in 2.2% of samples, SMAD family member 4 (SMAD4) in 4.4% of samples, epidermal growth factor receptor (EGFR) in 15.6% of samples, STK1 in 2.2% of samples, tumor protein 53 (TP53) in 15.6% of samples, and phosphatase and tensin homolog (PTEN) in 2.2% of samples. The following gene rearrangements were observed: anaplastic lymphoma kinase (ALK) in 8.9% of samples, RET in 2.2% of samples, and MET amplification in 17.8% of samples. The median total delivered SBRT dose was 50 grays (range, 48-60 grays) over a median of 5 fractions (range, 3-8 fractions). The KRAS mutation was associated with worse local control (odds ratio [OR], 3.64; P<.05). MET amplification was associated with worse regional (OR, 4.64; P<.05) and distant (OR, 3.73; P<.05) disease control. CONCLUSIONS: To the authors' knowledge, the current series is the first to quantify genetic mutations and their association with clinical outcomes in patients with early-stage LAC treated with SBRT. KRAS mutations were associated with worse local control and MET amplification was associated with worse regional and distant disease control, findings that need to be validated in a prospective setting.

Stereotactic body radiation therapy versus no treatment for early stage non-small cell lung cancer in medically inoperable elderly patients: A National Cancer Data Base analysis.

BACKGROUND: Stereotactic body radiation therapy (SBRT) has demonstrated high rates of local control with low morbidity and has now emerged as the standard of care for medically inoperable, early stage non-small cell lung cancer (NSCLC). However, the impact of lung SBRT on survival in the elderly population is less clear given competing comorbid conditions. An analysis of the National Cancer Data Base (NCDB) was undertaken to determine whether definitive SBRT improves survival relative to observation alone patients ages 70 years and older. METHODS: The NCDB, a retrospective national database that captures approximately 70% of all patients treated for cancer, was queried for patients aged 70 years or older with early stage (T1-T3N0M0) NSCLC from 2003 to 2006. Overall survival was compared between patients who received stereotactic body radiotherapy alone and those who received no treatment. An extended Cox proportional hazards model was applied to estimate the treatment effect of SBRT. RESULTS: In total, 3147 patients met the selection criteria for this analysis. SBRT was delivered to 258 patients (8.2%), and 2889 patients (91.8%) received no treatment. There was no significant difference in the distribution of Charlson/Deyo comorbidity index scores between the 2 groups (P = .076). Multivariable analysis revealed improved overall survival with SBRT compared with observation for the entire cohort (hazard ratio, 0.64; P < .001). CONCLUSIONS: SBRT is associated with improved survival in elderly patients with early stage NSCLC who have concurrent comorbid conditions compared with observation alone. The current data support the use of SBRT for the treatment of elderly patients with early stage NSCLC who have limiting comorbid conditions.

Transthoracic versus transhiatal resection for esophageal adenocarcinoma of the lower esophagus: A value-based comparison.

BACKGROUND AND OBJECTIVE: Our objective was to compare clinical outcomes, costs, and resource use based on operative approach, transthoracic (TT) or transhiatal (TH), for resection of esophageal cancer. METHODS: This cohort analysis utilized the Surveillance, Epidemiology, and End Results--Medicare linked data from 2002 to 2009. Only adenocarcinomas of the lower esophagus were examined to minimize confounding. Medicare data was used to determine episode of care costs and resource use. Propensity score matching was used to control for identified confounders. Kaplan-Meier method and Cox-proportional hazard modeling were used to compare long-term survival. RESULTS: 537 TT and 405 TH resections were identified. TT and TH esophagectomy had similar complication rates (46.7% vs. 50.8%), operative mortality (7.9% vs 7.1%), and 90 days readmission rates (30.5% vs. 32.5%). However, TH was associated with shorter length of stay (11.5 vs. 13.0 days, P = 0.006) and nearly $1,000 lower cost of initial hospitalization (P = 0.03). No difference in 5-year survival was identified (33.5% vs. 36%, P = 0.75). CONCLUSIONS: TH esophagectomy was associated with lower costs and shorter length of stay in an elderly Medicare population, with similar clinical outcomes to TT. The TH approach to esophagectomy for distal esophageal adenocarcinoma may, therefore, provide greater value (quality/cost).

Routine Implementation of Patient-Reported Outcomes Assessment Into Thoracic Surgery Practice.

BACKGROUND: Patient-reported outcomes (PROs) assessment is a necessary component of surgical outcome assessment and patient care. This study examined the success of routine PROs assessment in an academic-based thoracic surgery practice. METHODS: PROs, measuring pain intensity, physical function, and dyspnea, were routinely obtained using the National Institutes of Health-sponsored Patient-Reported Outcomes Measurement Information System (PROMIS) on all thoracic surgery patients beginning in April 2018 through January 2021. Questionnaires were administered electronically through a web-based platform at home or during the office visit. Completion rates and barriers were measured. RESULTS: A total of 9725 thoracic surgery office visits occurred during this time frame. PROs data were obtained in 6899 visits from a total of 3551 patients. The mean number of questions answered per survey was 22.4 ± 2.2. Overall questionnaire completion rate was 65.7%. A significant decline in survey completion was noted in April 2020, after which adjustments were made to allow for questionnaire completion through a mobile health platform. Overall monthly questionnaire completion rates ranged from 20% (April 2020) to 90% (October 2018). Mean T scores were dyspnea, 41.6 ± 12.3; physical function, 42.7 ± 10.5; and pain intensity, 52.8 ± 10.3. CONCLUSIONS: PROs can be assessed effectively in a thoracic surgery clinic setting, with minimal disruption of clinical activities. Future efforts should focus on facilitating PROs collection from disadvantaged patient populations and scaling implementation across programs.

Drivers of Cost Associated With Minimally Invasive Esophagectomy.

BACKGROUND: In this era of value-based healthcare, costs must be measured alongside patient outcomes to prioritize quality improvement and inform performance-based reimbursement strategies. We sought to identify drivers of costs for patients undergoing minimally invasive esophagectomy for esophageal cancer. METHODS: Patients who underwent minimally invasive esophagectomy for esophageal cancer from December 2008 to March 2020 were included. Our institutional Society of Thoracic Surgeons database was merged with financial data to determine inpatient direct accounting costs in 2020 US dollars for total, operative (surgery and anesthesia), and postoperative (intensive care, floor, radiology, laboratory, etc) services. A supervised machine learning quantitative method, the lasso estimator with 10-fold cross-validation, was applied to identify predictors of costs. RESULTS: In the study cohort (n = 240) most had ≥cT2 pathology (82%), adenocarcinoma histology (90%), and received neoadjuvant therapy (78%). Mean length of stay was 8.00 days (SD, 4.13) with 45% inpatient morbidity rate and no deaths. The largest proportions of cost were from the operating room (30%), inpatient floor (30%), and postanesthesia care/intensive care units (20%). Preoperative predictors of operative costs were age (-5.18% per decade [95% confidence interval {CI}, -9.95 to -0.27], P = .039), body mass index ≥ 30 (+12.9% [95% CI, 0.00-27.5], P = .050), forced expiratory volume in 1 second (-3.24% per 10% forced expiratory volume in 1 second [95% CI, -5.80 to -0.61], P = .017), and year of surgery (+2.55% [95% CI, 0.97-4.15], P = .002). Predictors of postoperative costs were postoperative renal failure (+91.6% [95% CI, 9.93-233.8], P = .022), respiratory failure (+414.6% [95% CI, 158.7-923.6], P < .001), pneumonia (+136.1% [95% CI, 71.1-225.8], P < .001), and reoperation (+60.5% [95% CI, 21.5-111.9], P = .001). CONCLUSIONS: Costs associated with minimally invasive esophagectomy are driven by preoperative risk factors and postoperative outcomes. These data enable surgeons and policymakers to reduce cost variation, improve quality through standardization, and ultimately provide greater value to patients.

Impact of Chest Wall Resection on Mortality After Lung Resection for Non-Small Cell Lung Cancer.

BACKGROUND: Lung cancer invading the chest wall is treated with concomitant en bloc lung and chest wall resection (CWR). It is unclear how CWR affects postoperative outcomes of lung resection. We hypothesized that CWR would be associated with increased risk of adverse outcomes after lung cancer resection. METHODS: We performed a retrospective analysis of The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database from 2016-2019. Patients with superior sulcus tumors were excluded. Patient demographic and operative outcomes were compared between those with and without CWR. Chest wall resection was added to existing STS lung risk models to determine the association with a composite adverse outcome, which included major morbidity and death. RESULTS: Among 41 310 lung resections, 306 (0.74%) occurred with concomitant CWR. Differences between those with and without CWR included demographic and comorbidities. Patients undergoing CWR were more likely to have the composite adverse outcome (64 of 306 [20.9%] vs 3128 of 41 004 [7.6%] for non-CWR resections, P < .001). Mortality was also increased among the CWR cohort (2.9% vs 1.1%, P = .003). CWR was associated with an increased risk of adverse composite outcome among all lung resection patients in a multivariable model (odds ratio 1.74, P = .0003) and the lobectomy subgroup (odds ratio 2.35, P < .0001). Among institutions with ≥10 lung resections, 49.1% performed lung resections with CWR. CONCLUSIONS: Concomitant CWR adds risk of adverse outcomes after lung cancer resection. As a subset of intuitions perform CWR, quality assessments should control for CWR. This variable will be incorporated into the STS lung cancer and lobectomy quality composite measures.

Current Penetration, Completeness, and Representativeness of The Society of Thoracic Surgeons Adult Cardiac Surgery Database.

BACKGROUND: The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) is the largest cardiac surgical database in the world. Linked data from STS ACSD and the Centers for Medicare and Medicaid Services (CMS) database were used to determine contemporary completeness, penetration, and representativeness of STS ACSD. METHODS: Variables common to both STS and CMS databases were used to link STS procedures to CMS data for all CMS coronary artery bypass grafting surgery (CABG) discharges between 2000 and 2018, inclusive. For each CMS CABG hospitalization, it was determined whether a matching STS record existed. RESULTS: Center-level penetration (number of CMS sites with at least 1 matched STS participant divided by total number of CMS CABG sites) increased from 45% in 2000 to 95% in 2018. In 2018, 949 of 1004 CMS CABG sites (95%) were linked to an STS site. Patient-level penetration (number of CMS CABG hospitalizations at STS sites divided by total number of CMS CABG hospitalizations) increased from 51% in 2000 to 97% in 2018. In 2018, 68,584 of 70,818 CMS CABG hospitalizations (97%) occurred at an STS site. Completeness of case inclusion at STS sites (number of CMS CABG cases at STS sites linked to STS records divided by total number of CMS CABG cases at STS sites) increased from 88% in 2000 to 98% in 2018. In 2018, 66,673 of 68,108 CMS CABG hospitalizations at STS sites (98%) were linked to an STS record. CONCLUSIONS: Linkage of the STS and CMS databases demonstrates high and increasing penetration and completeness of STS ACSD. STS ACSD now includes 97% of CABG in the United States.

Preoperative Lung Function Is Associated With Patient-Reported Outcomes After Lung Cancer Surgery.

BACKGROUND: Patient quality of life (QOL) is a critical outcomes measure in lung cancer surgery. Patient-reported outcomes (PROs) provide valuable insight into the patient experience and allow measurement of preoperative and postoperative QOL. Our objective was to determine which clinical factors predict differences in QOL, as measured by patient-reported physical function and pain intensity among patients undergoing minimally invasive lung cancer surgery. METHODS: PRO surveys assessing physical function and pain intensity were conducted using instruments from the National Institutes of Health Patient-Reported Outcomes Measurement Information System. PRO surveys were administered to patients undergoing minimally invasive lung cancer resections at preoperative, 1-month, and 6-month postoperative time points, in an academic institution. Linear mixed-effects regression models were constructed to assess the association between clinical variables on PRO scores over time. RESULTS: A total of 123 patients underwent a thoracoscopic lung resection for cancer. Mean age of the cohort was 67 ± 9.6 years, 43% were male, and 80% were White. When comparing clinical variables with PRO scores after surgery, lower diffusing capacity of the lungs for carbon monoxide (Dlco) was associated with significantly worse physical function (P < .01) and greater pain intensity scores (P < .01) at 6 months, with no differences identified at 1 month. No other studied clinical factor was associated with significant differences in PRO scores. CONCLUSIONS: Low preoperative Dlco was associated with significant decreases in PRO after minimally invasive lung cancer surgery. Dlco may be of utility in identifying patients who experience greater decline in QOL after surgery and for guiding surgical decision making.

STS Adult Cardiac Surgery Database: 2021 Update on Outcomes, Quality, and Research.

The Society of Thoracic Surgeons Adult Cardiac Surgery Database is the most mature and comprehensive cardiac surgery database. It has been the foundation for quality measurement and improvement activities in cardiac surgery, facilitated the generation of accurate risk adjusted performance benchmarks and serves as a platform for novel research. Recent enhancements have added to the database's functionality, ease of use, and value to multiple stakeholders. This report is the sixth in a series of annual reports that provide updated volumes, outcomes, database-related developments, quality improvement initiatives, and research summaries using the Adult Cardiac Surgery Database in the past year.

Initial and Longitudinal Cost of Surgical Resection for Lung Cancer.

BACKGROUND: The longitudinal cost of treating patients with non-small cell lung cancer (NSCLC) undergoing surgical resection has not been evaluated. We describe initial and 4-year resource use and cost for NSCLC patients aged 65 years of age or greater who were treated surgically between 2008 and 2013. METHODS: Using clinical data for NSCLC resections from The Society of Thoracic Surgeons General Thoracic Surgery Database linked to Medicare claims, resource use and cost of preoperative staging, surgery, and subsequent care through 4 years were examined ($2017). Cost of hospital-based care was estimated using cost-to-charge ratios; professional services and care in other settings were valued using reimbursements. Inverse probability weighting was used to account for administrative censoring. Outcomes were stratified by pathologic stage and by surgical approach for stage I lobectomy patients. RESULTS: Resection hospitalizations averaged 6 days and cost $31,900. In the first 90 days, costs increased with stage ($12,430 for stage I to $26,350 for stage IV). Costs then declined toward quarterly means more similar among stages. Cumulative costs ranged from $131,032 (stage I) to $205,368 (stage IV). In the stage I lobectomy cohort, patients selected for minimally invasive procedures had lower 4-year costs than did thoracotomy patients ($120,346 versus $136,250). CONCLUSIONS: The 4-year cost of surgical resection for NSCLC was substantial and increased with pathologic stage. Among stage I lobectomy patients, those selected for minimally invasive surgery had lower costs, particularly through 90 days. Potential avenues for improving the value of surgical resection include judicious use of postoperative intensive care and earlier detection and treatment of disease.

Association Between Patient Physical Function and Length of Stay After Thoracoscopic Lung Cancer Surgery.

Patient-reported outcomes (PRO) are an ideal method for measuring patient functional status. We sought to evaluate whether preoperative PRO were associated with resource utilization. We hypothesize that higher preoperative physical function PRO scores, measured via the NIH-sponsored Patient Reported Outcome Measurement Information System (PROMIS), are associated with shorter length of stay (LOS). Preoperative physical function scores were obtained using NIH PROMIS in a prospective observational study of patients undergoing minimally invasive surgery for lung cancer. Poisson regression models were constructed to estimate the association between the length of stay and PROMIS physical function T-score, adjusting for extent of resection, age, gender, and race. Due to the significant interaction between postoperative complications and physical function T-score, the relationship between physical function and LOS was described separately for each complication status. A total of 123 patients were included; 88 lobectomy, 35 sublobar resections. Mean age was 67 years, 35% were male, 65% were Caucasian. Among patients who had a postoperative complication, a lower preoperative physical function T-score was associated with progressively increasing LOS (P  value = 0.006). In particular, LOS decreased by 18% for every 10-point increase in physical function T-score. Among patients without complications, T-score was not associated with LOS (P = 0.86). Preoperative physical function measured via PRO identifies patients who are at risk for longer LOS following thoracoscopic lung cancer surgery. In addition to its utility for preoperative counseling and planning, these data may be useful in identifying patients who may benefit from risk-reduction measures.

The Society of Thoracic Surgeons Intermacs 2020 Annual Report.

The Society of Thoracic Surgeons (STS)-Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) 2020 Annual Report reviews outcomes on 25,551 patients undergoing primary isolated continuous-flow left ventricular assist device (LVAD) implantation between 2010 and 2019. In 2019, 3198 primary LVADs were implanted, which is the highest annual volume in Intermacs history. Compared with the previous era (2010-2014), patients who received an LVAD in the most recent era (2015-2019) were more likely to be African American (26.8% vs 22.9%, P < .0001) and more likely to be bridged to durable LVAD with temporary mechanical support devices (36.8% vs 26.0%, P < .0001). In 2019, 50% of patients were INTERMACS Profile 1 or 2 before durable LVAD, and 73% received an LVAD as destination therapy. Magnetic levitation technology has become the predominant design, accounting for 77% of devices in 2019. The 1- and 2-year survival in the most recent era has improved compared with 2010 to 2014 (82.3% and 73.1% vs 80.5% and 69.1%, respectively; P < .0001). Major bleeding and infection continue to be the leading adverse events. Incident stroke has declined in the current era to 12.7% at 1 year. STS-Intermacs research publications are highlighted, and the new quality initiatives are introduced.

Costs Associated With Lobectomy for Lung Cancer: An Analysis Merging STS and Medicare Data.

BACKGROUND: Costs related to care of patients who undergo lobectomy for lung cancer may vary depending on patient, disease, and treating facility characteristics. We aimed to identify underlying case mix factors that contribute to variability of 90-day costs of lobectomy for early-stage lung cancer. METHODS: The Society of Thoracic Surgeons General Thoracic Surgery Database was queried for lobectomy for clinical stage I lung cancer (2008-2013). Demographics, clinical outcomes, and 90-day episode-of-care costs across all care settings were analyzed for patients successfully linked to Medicare data. Hospital costs were estimated from charges using cost-to-charge ratios. Comprehensive regression models were created to identify impact of preoperative patient factors and hospital characteristics on costs, and to delineate additive costs due to perioperative outcomes and complications. RESULTS: The mean 90-day cost for lobectomy was $45,080 ± $38,239. Variables associated with significant additive costs were age greater than or equal to 75 years, American Society of Anesthesiologists classification III or IV, forced expiratory volume in 1 second less than 80% predicted, body mass index less than 18.5 or greater than 35, current or past smoker, cerebrovascular disease, chronic kidney disease, impaired functional status, open thoracotomy, prolonged operative time, government hospitals, metropolitan setting, and geographic location. Patients with 1 or more postoperative complication resulted in an overall mean added cost of $27,259. Added costs increased with the number of complications; isolated recurrent laryngeal nerve paresis ($3,911) and respiratory failure ($35,011) were associated with the least and most additive cost, respectively. CONCLUSIONS: Lobectomy is associated with substantial variability of episode-of-care costs. Variability is driven by patient demographic and clinical factors, hospital characteristics, and the occurrence and severity of complications.
