RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
