ABSTRACT
The Society of Thoracic Surgeons Workforce on Evidence-Based Surgery provides this document on management of pleural drains after pulmonary lobectomy. The goal of this consensus document is to provide guidance regarding pleural drains in 5 specific areas: (1) choice of drain, including size, type, and number; (2) management, including use of suction vs water seal and criteria for removal; (3) imaging recommendations, including the use of daily and postpull chest roentgenograms; (4) use of digital drainage systems; and (5) management of prolonged air leak. To formulate the consensus statements, a task force of 15 general thoracic surgeons was invited to review the existing literature on this topic. Consensus was obtained using a modified Delphi method consisting of 2 rounds of voting until 75% agreement on the statements was reached. A total of 13 consensus statements are provided to encourage standardization and stimulate additional research in this important area.
ABSTRACT
Cross-table ventilation during tracheal resection via posterolateral thoracotomy presents a technical challenge. With the ubiquity of venovenous extracorporeal membrane oxygenation (VV-ECMO), there is now a safe and feasible alternative for intraoperative respiratory support. Airway surgery on ECMO avoids prolonged periods of apnea or single lung ventilation, allowing patients with poor lung function to undergo surgery. Image-guided femoro-femoral cannulation using a low-dose heparin protocol minimizes the risk of bleeding while uncluttering the surgical field. By eliminating the need to constantly reposition the endotracheal tube, visualization is improved, and the rhythm of the case is maintained, which can shorten the anastomotic time. Here, we present a case where venovenous ECMO and total intravenous anesthesia were used to completely support a patient undergoing major tracheal surgery without the need for cross-table ventilation.
ABSTRACT
BACKGROUND: Esophagectomy is an important, but potentially morbid, operation used to treat benign and malignant conditions that may significantly impact patient quality of life (QOL). Patient-reported outcomes (PROs) are measures of QOL that come directly from patient self-report. This study characterizes patterns of change and recovery in PROs in the first year after esophagectomy. METHODS: Longitudinal QOL scores measuring physical function, pain, and dyspnea were obtained from esophagectomy patients during all clinic visits. PRO scores were obtained using the National Institutes of Health-sponsored Patient-Reported Outcomes Measurement Information System from April 2018 to February 2021. Mean PRO scores over 100 days after surgery were compared with baseline PRO scores using mixed-effects modeling with compound symmetry correlational structure. RESULTS: One hundred three patients with PRO results were identified. Reasons for esophagectomy were malignancy (87.4%), achalasia (5.8%), stricture (5.8%), and dysplasia (1.0%). When comparing mean PRO scores at visits ≤ 50 days after surgery with preoperative PRO scores, physical function scores declined by 27.3% (P < .001), whereas dyspnea severity and pain interference scores had increased by 24.5% (P < .001) and 17.1% (P < .001), respectively. Although recovery occurred over the course of the 100 days after surgery, mean physical function scores and dyspnea scores were still 12.7% (P = .02) and 26.4% (P = .001) worse, respectively, than mean preoperative levels. CONCLUSIONS: Despite declines in QOL scores immediately after esophagectomy, recovery back toward baseline was observed during the first 100 days. These findings are of considerable importance when counseling patients regarding esophagectomy, tracking recovery, and implementing quality improvement initiatives. Further long-term follow-up is needed to determine recovery beyond 100 days.

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.

BACKGROUND: Health care professionals (HCPs) performing tracheostomies in patients with COVID-19 may be at increased risk of infection. OBJECTIVE: To evaluate factors underlying HCPs' COVID-19 infection and determine whether tracheostomy providers report increased rates of infection. METHODS: An anonymous international survey examining factors associated with COVID-19 infection was made available November 2020 through July 2021 to HCPs at a convenience sample of hospitals, universities, and professional organizations. Infections reported were compared between HCPs involved in tracheostomy on patients with COVID-19 and HCPs who were not involved. RESULTS: Of the 361 respondents (from 33 countries), 50% (n = 179) had performed tracheostomies on patients with COVID-19. Performing tracheostomies on patients with COVID-19 was not associated with increased infection in either univariable (P = .06) or multivariable analysis (odds ratio, 1.48; 95% CI, 0.90-2.46; P = .13). Working in a low- or middle-income country (LMIC) was associated with increased infection in both univariable (P < .001) and multivariable analysis (odds ratio, 2.88; CI, 1.50-5.53; P = .001). CONCLUSIONS: Performing tracheostomy was not associated with COVID-19 infection, suggesting that tracheostomies can be safely performed in infected patients with appropriate precautions. However, HCPs in LMICs may face increased infection risk.

Timing of tracheostomy in patients with COVID-19 has attracted substantial attention. Initial guidelines recommended delaying or avoiding tracheostomy due to the potential for particle aerosolization and theoretical risk to providers. However, early tracheostomy could improve patient outcomes and alleviate resource shortages. This study compares outcomes in a diverse population of hospitalized COVID-19 patients who underwent tracheostomy either "early" (within 14 d of intubation) or "late" (more than 14 d after intubation). DESIGN: International multi-institute retrospective cohort study. SETTING: Thirteen hospitals in Bolivia, Brazil, Spain, and the United States. PATIENTS: Hospitalized patients with COVID-19 undergoing early or late tracheostomy between March 1, 2020, and March 31, 2021. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: A total of 549 patients from 13 hospitals in four countries were included in the final analysis. Multivariable regression analysis showed that early tracheostomy was associated with a 12-day decrease in time on mechanical ventilation (95% CI, -16 to -8; p < 0.001). Further, ICU and hospital lengths of stay in patients undergoing early tracheostomy were 15 days (95% CI, -23 to -9 d; p < 0.001) and 22 days (95% CI, -31 to -12 d) shorter, respectively. In contrast, early tracheostomy patients experienced lower risk-adjusted survival at 30-day post-admission (hazard ratio, 3.0; 95% CI, 1.8-5.2). Differences in 90-day post-admission survival were not identified. CONCLUSIONS: COVID-19 patients undergoing tracheostomy within 14 days of intubation have reduced ventilator dependence as well as reduced lengths of stay. However, early tracheostomy patients experienced lower 30-day survival. Future efforts should identify patients most likely to benefit from early tracheostomy while accounting for location-specific capacity.
ABSTRACT
BACKGROUND: Patients undergoing surgery for early stage non-small cell lung cancer (NSCLC) may be at high risk for postoperative mortality. Access to stereotactic body radiation therapy (SBRT) may facilitate more appropriate patient selection for surgery. RESEARCH QUESTION: Is postoperative mortality associated with early stage NSCLC lower at facilities with higher use of SBRT? STUDY DESIGN AND METHODS: Patients with early stage NSCLC reported to the National Cancer Database between 2004 and 2015 were included. Use of SBRT was defined by each facility's SBRT experience (in years) and SBRT to surgery volume ratios. Multivariate logistic regression was used to test for the associations between SBRT use and postoperative mortality. RESULTS: The study cohort consisted of 202,542 patients who underwent surgical resection of cT1-T2N0M0 NSCLC tumors. The 90-day postoperative mortality rate declined during the study period from 4.6% to 2.6% (P < .001), the proportion of facilities that used SBRT increased from 4.6% to 77.5% (P < .001), and the proportion of patients treated with SBRT increased from 0.7% to 15.4% (P < .001). On multivariate analysis, lower 90-day postoperative mortality rates were observed at facilities with > 6 years of SBRT experience (OR, 0.84; 95% CI, 0.76-0.94; P = .003) and SBRT to surgery volume ratios of more than 17% (OR, 0.85; 95% CI, 0.79-0.92; P < .001). Ninety-day mortality also was associated with surgical volume, region, year, age, sex, and race, among other covariates. Interaction testing between these covariates showed negative results. INTERPRETATION: Patients who underwent resection for early stage NSCLC at facilities with higher SBRT use showed lower rates of postoperative mortality. These findings suggest that the availability and use of SBRT may improve the selection of patients for surgery who are predicted to be at high risk of postoperative mortality.

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.

OBJECTIVE: Octogenarians comprise an increasing proportion of patients presenting with non-small-cell lung cancer (NSCLC). This study examines postoperative morbidity and mortality, and long-term survival in octogenarians undergoing thoracoscopic anatomic lung resection for NSCLC, compared with younger cohorts. METHODS: We conducted a retrospective review of our institutional Society of Thoracic Surgeons General Thoracic Surgery Database of all patients ≥60 years old undergoing elective lobectomy or segmentectomy for pathologic stage I, II, and IIIA NSCLC between 2009 and 2018. Results were compared between octogenarians (n = 71) to 2 younger cohorts of 60- to 69-year-olds (n = 359) and 70- to 79-year-olds (n = 308). Long-term survival among octogenarians was graphically summarized using the Kaplan-Meier method. Cox regression analysis was used to identify preoperative risk factors for mortality. RESULTS: A greater proportion of octogenarians required intensive care unit admission and discharge to extended-care facilities; however, postoperative length of stay was similar between groups. Among postoperative complications, arrhythmia and renal failure were more likely in the older cohort. Compared to the youngest cohort, in-hospital and 30-day mortality were highest among octogenarians. Overall survival among octogenarians at 1, 3, and 5 years was 87.3%, 61.8%, and 50.5%, respectively. On multivariable Cox regression analysis of baseline demographic variables, presence of stroke (hazard ratio [HR] = 28.5, 95% confidence interval [CI]: 6.1 to 132.7, P < 0.001) and coronary artery disease (HR = 2.5, 95% CI: 1.2 to 5.3, P = 0.02) were significant predictors of overall mortality among octogenarians. CONCLUSIONS: Thoracoscopic resection can be performed with favorable early postoperative outcomes among octogenarians. Long-term survival, although comparable to their healthy peers, is worse than those of younger cohorts. Further study into preoperative risk stratification and alternative therapies among octogenarians is needed.

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⯠valueâ¯=â¯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 (Pâ¯=â¯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.

BACKGROUND: Socioeconomic factors play key roles in surgical outcomes. Socioeconomic data within The Society of Thoracic Surgeons (STS) General Thoracic Surgery Database (GTSD) are limited. Therefore, we utilized community size as a surrogate to understand socioeconomic differences in lung cancer resection outcomes. METHODS: We retrospectively reviewed all lung cancer resections from January 2012 to January 2017 in the STS GTSD. This captured 68,722 patients from 286 centers nationwide. We then linked patient zip codes with 2013 Rural-Urban Continuum Codes to understand the association between community size and postoperative outcomes. Demographic and clinical variables were evaluated for relationships with 30-day mortality, major morbidity, and readmission. RESULTS: Zip codes were included in 47.2% of patients. Zip-coded patients were older, were more comorbid, had less advanced disease, and were more commonly treated with minimally invasive approaches than were those without zip code classification. For geocoded patients, multivariable analyses demonstrated that sex, insurance payor, and hospital region were associated with all 3 major endpoints. Community size, based on Rural-Urban Continuum Codes coding, was not associated with any primary endpoint. Invasive mediastinal staging was related to morbidity, greater pathological stage predicted mortality, and worsened clinical stage was associated with readmission. More invasive surgery and greater extent of lung resection were associated with all primary endpoints. CONCLUSIONS: Incomplete data capture can promote selection bias within the STS GTSD and skew outcomes reporting. Moreover, community size is an insufficient surrogate, compared with sex, insurance payor, hospital region, for understanding socioeconomic differences in lung cancer resection outcomes.

Patient-centered care is a growing focus of research and modern surgical practice. To this end, there has been an ever-increasing utilization of patient reported outcomes (PRO) and health-related quality of life metrics (HR-QOL) in thoracic surgery research. Here we describe reasons and methods for integration of PRO measurement into routine thoracic surgical practice, commonly utilized PRO measurement instruments, and several examples of successful integration.
ABSTRACT
OBJECTIVE: To assess feasibility of modified protocol during percutaneous tracheostomy in coronavirus disease 2019 pandemic era. DESIGN: A retrospective review of cohort who underwent percutaneous tracheostomy with modified protocol. SETTINGS: Medical, surgical, and neurologic ICUs. SUBJECTS: Patients admitted in medical, surgical, and neurologic units with prolonged need of mechanical ventilation or inability to liberate from the ventilator. INTERVENTIONS: A detailed protocol was written. Steps were defined to be performed before apnea and during apnea. A feasibility study of 28 patients was conducted. The key aerosol-generating portions of the procedure were performed with the ventilator switched to standby mode with the patient apneic. MEASUREMENTS AND MAIN RESULTS: Data including patient demographics, primary diagnosis, age, body mass index, and duration of apnea time during the tracheostomy were collected. Average ventilator standby time (apnea) during the procedure was 238 seconds (3.96 min) with range 149 seconds (2.48 min) to 340 seconds (5.66 min). Single-use (disposable) bronchoscopes (Ambu A/S [Ballerup, Denmark] or Glidescope [Verathon, Inc., Bothell, WA]) were used during all procedures except in nine. No desaturation events occurred during any procedure. CONCLUSIONS: Percutaneous tracheostomy performed with apnea protocol may help minimize aerosolization, reducing risk of exposure of coronavirus disease 2019 to staff. It can be safely performed with portable bronchoscopes to limit staff and minimize the surfaces requiring disinfection post procedure.
ABSTRACT
Quality-focused, cost-effective, patient-centered care is at the forefront of current healthcare reform. Recent data show that enhanced recovery after surgery (ERAS) results in improved surgical outcomes and decreased hospital costs. As a result, ERAS has been widely accepted among multiple surgical subspecialties as a modality for increasing the value of healthcare delivered to our patients. While this objective data is convincing for practitioners and administrators alike, how ERAS directly impacts the patient experience is unclear. Patient reported outcomes (PRO) are starting to drive patterns of healthcare delivery and influence surgical decision-making. In order to improve surgical outcomes and deliver patient-centered care, it is imperative that clinicians start reviewing objective metrics contained within morbidity and mortality data alongside subjective data regarding patients' experience. This article reviews the current data surrounding both ERAS and PROs within thoracic surgery and investigates how the two concepts are ultimately related.
ABSTRACT
Historically, surgical outcomes research has focused on objective endpoints that are straightforward to measure and interpret using patient medical records, institutional databases, and national registries. In recent years, such data have been used to drive quality improvement, influence healthcare reform, and impact reimbursement of healthcare spending. In order to continue improving outcomes and deliver high-quality patient-centered care, it is imperative that clinicians review not only objective morbidity and mortality data, but also subjective data regarding patients' experience. Patient-reported outcomes (PRO) are starting to drive patterns of healthcare delivery and influence surgical decision-making. The current article reviews the historical background of PRO, tools for integrating it into surgical outcomes research, current data reported within the literature, and future implications within thoracic surgery.

BACKGROUND: Current studies in cardiothoracic clinical research frequently fail to use end points that are most meaningful to patients, including measures associated with quality of life. Patient-reported outcomes (PROs) represent an underused but important component of high-quality patient-centered care. Our objective was to highlight important principles of PRO measurement, describe current use in cardiothoracic operations, and discuss the potential for and challenges associated with integration of PROs into large clinical databases. METHODS: We performed a literature review by using the PubMed/EMBASE databases. Clinical articles that focused on the use of PROs in cardiothoracic surgical outcomes measurement or clinical research were included in this review. RESULTS: PROs measure the outcomes that matter most to patients and facilitate the delivery of patient-centered care. When effectively used, PRO measures have provided detailed and nuanced quality-of-life data for comparative effectiveness research. However, further steps are needed to better integrate PROs into routine clinical care. CONCLUSIONS: Incorporation of PROs into routine clinical practice is essential for delivering high-quality patient-centered care. Future integration of PROs into prospectively collected registries and databases, including that The Society of Thoracic Surgeons National Database, has the potential to enrich comparative effectiveness research in cardiothoracic surgery.

BACKGROUND: Postoperative complications result in significantly increased health care expenditures. The objective of this study was to examine 90-day excess costs associated with inpatient complications after esophagectomy and their predictive factors, by using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. METHODS: The study examined patients older than 65 years of age with a diagnosis from 2002 to 2009 and who were undergoing esophagectomy for cancer in the SEER-Medicare database. Quantile regression models were fit at 5% intervals for excess 90-day cost associated with perioperative complications while controlling for baseline characteristics. Excess cost was defined as the difference in total cost for patients with versus without the complication. Analyses were stratified by patients' characteristics to identify factors predictive of excess cost. RESULTS: A total of 1,462 patients were identified in the cohort; 51% had at least one complication. Significant excess cost was associated with pulmonary and mechanical wound complications across all quantiles (p < 0.05). Infectious (0.35 to 0.75 quantiles), intraoperative (0.05 to 0.85 quantiles), and systemic (0.30 to 0.85 quantiles) complications were associated with higher costs. Further, excess costs were significantly elevated in the higher quantiles. At the 0.50 quantile (median) of total cost distribution, excess cost in patients with any complication were significantly higher in patients with the following characteristics: transthoracic esophagectomy, emergency esophagectomy, Charlson Comorbidity Index >0, living in a nonmetropolitan area or poorer community, or treated in larger hospitals; no such difference was identified in patients without complications. CONCLUSIONS: Complications after esophagectomy result in significant excess 90-day cost. Efforts at cost reduction and quality improvement will need to focus on reducing complications, in particular pulmonary and infectious, as well as risk factors for higher complication costs.

OBJECTIVE: To report the first analysis of long-term outcomes using near-infrared (NIR) image-guided sentinel lymph node (SLN) mapping in non-small cell lung cancer (NSCLC). METHODS: Retrospective analysis of patients with NSCLC enrolled in 2 prospective phase 1 NIR-guided SLN mapping trials, including an indocyanine green (ICG) dose-escalation trial, was performed. All patients underwent NIR imaging for SLN identification followed by multistation mediastinal lymph node sampling (MLNS) and pathologic assessment. Disease-free (DFS) and overall survival (OS) were compared between patients with NIR+ SLN (SLN group) and those without (non-SLN group). RESULTS: SLN detection, recurrence, DFS, and OS were assessed in 42 patients with NSCLC who underwent intraoperative peritumoral ICG injection, NIR imaging, and MLNS. NIR+ SLNs were identified in 23 patients (SLN group), whereas SLNs were not identified in 19 patients enrolled before ICG dose and camera optimization (non-SLN group). Median follow-up was 44.5 months. Pathology from NIR+ SLNs was concordant with overall nodal status in all 23 patients. Sixteen patients with SLN were deemed pN0 and no recurrences were, whereas 4 of 15 pN0 non-SLN patients developed nodal or distant recurrent disease. Comparing SLN versus non-SLN pN0 patients, the probability of 5-year OS is 100% versus 70.0% (P = .062) and 5-year DFS is statistically significantly improved at 100% versus 66.1% (P = .036), respectively. Among the 11 pN+ patients, 7 were in the SLN group, with >40% showing metastases in the SLN alone. CONCLUSIONS: Patients with pN0 SLNs showed favorable disease-free and overall survival. This preliminary review of NIR SLN mapping in NSCLC suggests that pN0 SLNs may better represent true N0 status. A larger clinical trial is planned to validate these findings.

BACKGROUND: We previously reported that early stage lung cancer patients who are considered high risk for surgery can undergo resection with favorable perioperative results and long-term mortality. To further elucidate the role of surgical resection in this patient cohort, this study evaluated the length of stay and total hospitalization cost among patients classified as standard or high risk with early stage lung cancer who underwent pulmonary resection. METHODS: A total of 490 patients from our institutional Society of Thoracic Surgeons data from 2009 to 2013 underwent resection for clinical stage I lung cancer. High-risk patients were identified by American College of Surgeons Oncology Group z4032-z4099 criteria. Demographics, length of stay, and hospitalization cost between high-risk and standard-risk patients undergoing lobectomy and sublobar resection were compared. Univariate analysis was performed using the chi-square test or Fisher's exact test. Multivariate analysis was performed using a linear regressions model. RESULTS: A total of 180 (37%) of patients were classified as high risk. These patients were older (70 years of age vs. 65 years of age; p < 0.0001), had worse forced expiratory volume in 1 second (57% vs. 85%; p < 0.0001), and had worse diffusion capacity of carbon dioxide (47% vs. 77%; p < 0.0001). The baseline cost and length of stay was represented by a thoracoscopic wedge resection in a standard-risk patient. A larger extent of resection, thoracotomy, or high-risk classification increased the cost and length of stay. CONCLUSIONS: Our previous study showed that good clinical outcomes after surgery for early stage lung cancer can be achieved in patients classified as high risk. In this study, although surgery in high-risk patients led to slightly increased costs, these costs seemed negligible when viewed along with the patients' excellent short-term and long-term results. This study suggests that surgical resection on high-risk patients with early stage lung cancer is associated with acceptable hospital lengths of stay and overall cost when compared with standard-risk patients.
