Cost effectiveness of commercial portable ex vivo lung perfusion at a low-volume US lung transplant center.

BACKGROUND: Portable ex vivo lung perfusion during lung transplantation is a resource-intensive technology. In light of its increasing use, we evaluated the cost-effectiveness of ex vivo lung perfusion at a low-volume lung transplant center in the USA. METHODS: Patients listed for lung transplantation (2015-2021) in the United Network for Organ Sharing database were included. Quality-of-life was approximated by Karnofsky Performance Status scores 1-year post-transplant. Total transplantation encounter and 1-year follow-up costs accrued by our academic center for patients listed from 2018 to 2021 were obtained. Cost-effectiveness was calculated by evaluating the number of patients attaining various Karnofsky scores relative to cost. RESULTS: Of the 13 930 adult patients who underwent lung transplant in the United Network for Organ Sharing database, 13 477 (96.7%) used static cold storage and 453 (3.3%) used ex vivo lung perfusion, compared to 30/58 (51.7%) and 28/58 (48.3%), respectively, at our center. Compared to static cold storage, median total costs at 1 year were higher for ex vivo lung perfusion ($918 000 vs. $516 000; p = 0.007) along with the cost of living 1 year with a Karnofsky functional status of 100 after transplant ($1 290 000 vs. $841 000). In simulated scenarios, each Karnofsky-adjusted life year gained by ex vivo lung perfusion was 1.00-1.72 times more expensive. CONCLUSIONS: Portable ex vivo lung perfusion is not currently cost-effective at a low-volume transplant centers in the USA, being 1.53 times more expensive per Karnofsky-adjusted life year. Improving donor lung and/or recipient biology during ex vivo lung perfusion may improve its utility for routine transplantation.

Implementing a Frailty-Specific Postoperative Order Set to Improve Postoperative Outcomes in Frail Adults After Elective Thoracic Surgery.

BACKGROUND: Frailty is independently associated with adverse patient outcomes after surgery. The current standards of postoperative care rarely consider frailty status. LOCAL PROBLEM: There was no standardized protocol to optimize specialized postoperative care for frail patients at an academic medical center. METHODS: A quasi-experimental pre-/postimplementation study design, using the Reach, Effectiveness, Adoption, Implementation, Maintenance implementation framework, was utilized. INTERVENTIONS: A frailty-specific postoperative order set (FPOS) was developed, including tailored nursing care, activity levels, and nutritional goals. RESULTS: There were significant improvements in nurse's self-reported familiarity with frailty ( P = .003) and FPOS awareness ( P < .001). The number of orders for delirium prevention, elimination, nutrition, sleep promotion, and sensory support increased ( P < .001). CONCLUSIONS: Implementing an FPOS showed improvements in nurse frailty knowledge, awareness, and order set utilization.

Donor leukocyte trafficking during human ex vivo lung perfusion.

BACKGROUND: Ex vivo lung perfusion (EVLP) is used to assess and preserve lungs prior to transplantation. However, its inherent immunomodulatory effects are not completely understood. We examine perfusate and tissue compartments to determine the change in immune cell composition in human lungs maintained on EVLP. METHODS: Six human lungs unsuitable for transplantation underwent EVLP. Tissue and perfusate samples were obtained during cold storage and at 1-, 3- and 6-h during perfusion. Flow cytometry, immunohistochemistry, and bead-based immunoassays were used to measure leukocyte composition and cytokines. Mean values between baseline and time points were compared by Student's t test. RESULTS: During the 1st hour of perfusion, perfusate neutrophils increased (+22.2 ± 13.5%, p < 0.05), monocytes decreased (-77.5 ± 8.6%, p < 0.01) and NK cells decreased (-61.5 ± 22.6%, p < 0.01) compared to cold storage. In contrast, tissue neutrophils decreased (-22.1 ± 12.2%, p < 0.05) with no change in monocytes and NK cells. By 6 h, perfusate neutrophils, NK cells, and tissue neutrophils were similar to baseline. Perfusate monocytes remained decreased, while tissue monocytes remained unchanged. There was no significant change in B cells or T cell subsets. Pro-inflammatory cytokines (IL-1b, G-CSF, IFN-gamma, CXCL2, CXCL1 granzyme A, and granzyme B) and lymphocyte activating cytokines (IL-2, IL-4, IL-6, IL-8) increased during perfusion. CONCLUSIONS: Early mobilization of innate immune cells occurs in both perfusate and tissue compartments during EVLP, with neutrophils and NK cells returning to baseline and monocytes remaining depleted after 6 h. The immunomodulatory effect of EVLP may provide a therapeutic window to decrease the immunogenicity of lungs prior to transplantation.

Fair and equitable subject selection in concurrent COVID-19 clinical trials.

Clinical trials emerged in rapid succession as the COVID-19 pandemic created an unprecedented need for life-saving therapies. Fair and equitable subject selection in clinical trials offering investigational therapies ought to be an urgent moral concern. Subject selection determines the distribution of risks and benefits, and impacts the applicability of the study results for the larger population. While Research Ethics Committees monitor fair subject selection within each trial, no standard oversight exists for subject selection across multiple trials for the same disease. Drawing on the experience of multiple clinical trials at a single academic medical centre in the USA, we posit that concurrent COVID-19 trials are liable to unfair and inequitable subject selection on account of scientific uncertainty, lack of transparency, scarcity and, lastly, structural barriers to equity compounded by implicit bias. To address the critical gap in the current literature and international regulation, we propose new ethical guidelines for research design and conduct that bolsters fair and equitable subject selection. Although the proposed guidelines are tailored to the research design and protocol of concurrent trials in the COVID-19 pandemic, they may have broader relevance to single COVID-19 trials.

Determinants of electrocardiographic abnormalities in patients with pectus excavatum.

BACKGROUND: Electrocardiographic abnormalities such as cardiac axis deviation, conduction abnormalities and ST-segment, and T &P wave abnormalities have been reported in patients with pectus excavatum. The precise determinants of these electrocardiographic abnormalities have however not been systematically evaluated. We therefore carried out this exploratory study to assess the electrocardiographic abnormalities and their determinants in children and young adults with pectus excavatum. METHODS: Patients aged between 6 and 22 years with unrepaired pectus excavatum were eligible for enrollment in this preliminary hypothesis generating study, if they were seen at University of Chicago Medical Center between Jan 1, 2017 to Nov 30, 2020, and underwent an electrocardiogram during comprehensive evaluation for pectus excavatum. Pertinent data was collected from the medical charts. Unadjusted and adjusted logistic regression models were used to determine the effect of variables including age, BMI, inspiratory Haller's index, gender, right ventricular geometric distortion and FEV1/FVC (% predicted) on odds of electrocardiographic abnormalities (primary outcome variable). P-values of <0.05 were considered significant. RESULTS: The study group (16.6 ± 2.9 years, 80% symptomatic) consisted of 28 patients [Caucasian, male (n = 24, 86% each)]. A high proportion (86%) of these patients had geometric distortion of the right ventricle on noninvasive imaging and these patients had a higher Haller's index (4.4 ± 0.95 vs 3.3 ± 0.2, p = 0.03). Approximately 60% of the patients had an abnormal electrocardiogram. Unadjusted and adjusted logistic regression models were utilized to study the determinants of these electrocardiographic abnormalities. Haller's index, BMI, age, gender, geometric distortion of the right ventricle and lung function parameters [FEV1/FEV (% predicted)] were not associated with increased odds of electrocardiographic abnormalities. CONCLUSIONS: Electrocardiographic abnormalities, particularly deviation of cardiac axis, are common in patients with pectus excavatum. In this exploratory hypothesis generating study, Haller's index and geometric distortion of the right ventricle were not associated with these abnormalities. However, systematic multicentric efforts are needed to better define electrocardiographic abnormalities in patients with pectus excavatum and elucidate their precise determinants.

Update on Lung Cancer Screening.

Over the past 10 years, there has been substantial progress in the study and implementation of lung cancer screening using low-dose computed tomography (LDCT). The National Lung Screening Trial, the recently reported NELSON (NEderlands-Leuvens Longkanker Screenings ONderzoek) trial, and other European trials provide strong evidence for the efficacy of LDCT to reduce lung cancer mortality. This has resulted in the United State's Preventative Task Force and numerous professional medical societies adopting lung cancer screening recommendations. Despite the general acceptance of the positive effect of screening, low adoption and implementation rates remain nationally. In this article, the authors discuss the evolution and current state of the evidence for LDCT screening for lung cancer. The authors will also review the associated risks, cost, and challenges of implementation of an LDCT screening program.

The Role of Surgery in Management of Locally Advanced Non-Small Cell Lung Cancer.

OPINION STATEMENT: Patients with locally advanced non-small cell lung cancer (NSCLC) are treated for cure, but treatment decisions are not straightforward. Chemotherapy is essential due to the high risk of systemic relapse, but local therapy is also required for cure. In the small subset of stage III patients with N0 or N1 disease, surgery is typically the initial therapy and extended resections are frequent. The majority of IIIA patients present with N2 disease and treatment paradigms for these patients are controversial, particularly concerning the role of resection. Surgery has a limited role in bulky IIIA, IIIB, and IIIC disease, which is typically treated with combined systemic therapy and radiation. The authors believe that in resectable IIIA disease, the addition of surgery to multimodality treatment appears to improve local control and overall survival. Induction therapy is essential, and the use of chemotherapy alone or chemoradiotherapy remains an area of debate. Pneumonectomy should be used with caution in IIIA disease, as numerous prospective trials have noted excessive perioperative mortality. The introduction of immunotherapies in this stage may quickly transform treatment decisions.

Evaluation of the airway microbiome in nontuberculous mycobacteria disease.

Aspiration is associated with nontuberculous mycobacterial (NTM) pulmonary disease and airway dysbiosis is associated with increased inflammation. We examined whether NTM disease was associated with a distinct airway microbiota and immune profile.297 oral wash and induced sputum samples were collected from 106 participants with respiratory symptoms and imaging abnormalities compatible with NTM. Lower airway samples were obtained in 20 participants undergoing bronchoscopy. 16S rRNA gene and nested mycobacteriome sequencing approaches characterised microbiota composition. In addition, inflammatory profiles of lower airway samples were examined.The prevalence of NTM+ cultures was 58%. Few changes were noted in microbiota characteristics or composition in oral wash and sputum samples among groups. Among NTM+ samples, 27% of the lower airway samples were enriched with Mycobacterium A mycobacteriome approach identified Mycobacterium in a greater percentage of samples, including some nonpathogenic strains. In NTM+ lower airway samples, taxa identified as oral commensals were associated with increased inflammatory biomarkers.The 16S rRNA gene sequencing approach is not sensitive in identifying NTM among airway samples that are culture-positive. However, associations between lower airway inflammation and microbiota signatures suggest a potential role for these microbes in the inflammatory process in NTM disease.

Surgical Treatment of Early l Stage Lung Cancer: What has Changed and What will Change in the Future.

Recent advances in the surgical treatment of early stage non-small cell lung cancer (NSCLC) have focused heavily on making procedures less invasive, less radical, and better tolerated. Advances in accuracy and increased utilization of cross-sectional imaging allows for diagnosis of smaller and more indolent tumors and preinvasive lesions. Similar to advanced disease, early-stage treatment is now being tailored to individual patients and their tumors. Sublobar resections are gaining acceptance as an oncologically equivalent approach to lobectomy in well-selected stage I patients. Minimally invasive approaches either by video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracic surgery are becoming the procedures of choice for anatomic NSCLC resections and provide decreased perioperative complications and increased tolerability, especially in the elderly and medically high-risk patients. Reports of even less invasive techniques including uniportal VATS and nonintubated lobar resections are now appearing in the literature.

Fibulin-3 as a blood and effusion biomarker for pleural mesothelioma.

BACKGROUND: New biomarkers are needed to detect pleural mesothelioma at an earlier stage and to individualize treatment strategies. We investigated whether fibulin-3 in plasma and pleural effusions could meet sensitivity and specificity criteria for a robust biomarker. METHODS: We measured fibulin-3 levels in plasma (from 92 patients with mesothelioma, 136 asbestos-exposed persons without cancer, 93 patients with effusions not due to mesothelioma, and 43 healthy controls), effusions (from 74 patients with mesothelioma, 39 with benign effusions, and 54 with malignant effusions not due to mesothelioma), or both. A blinded validation was subsequently performed. Tumor tissue was examined for fibulin-3 by immunohistochemical analysis, and levels of fibulin-3 in plasma and effusions were measured with an enzyme-linked immunosorbent assay. RESULTS: Plasma fibulin-3 levels did not vary according to age, sex, duration of asbestos exposure, or degree of radiographic changes and were significantly higher in patients with pleural mesothelioma (105±7 ng per milliliter in the Detroit cohort and 113±8 ng per milliliter in the New York cohort) than in asbestos-exposed persons without mesothelioma (14±1 ng per milliliter and 24±1 ng per milliliter, respectively; P<0.001). Effusion fibulin-3 levels were significantly higher in patients with pleural mesothelioma (694±37 ng per milliliter in the Detroit cohort and 636±92 ng per milliliter in the New York cohort) than in patients with effusions not due to mesothelioma (212±25 and 151±23 ng per milliliter, respectively; P<0.001). Fibulin-3 preferentially stained tumor cells in 26 of 26 samples. In an overall comparison of patients with and those without mesothelioma, the receiver-operating-characteristic curve for plasma fibulin-3 levels had a sensitivity of 96.7% and a specificity of 95.5% at a cutoff value of 52.8 ng of fibulin-3 per milliliter. In a comparison of patients with early-stage mesothelioma with asbestos-exposed persons, the sensitivity was 100% and the specificity was 94.1% at a cutoff value of 46.0 ng of fibulin-3 per milliliter. Blinded validation revealed an area under the curve of 0.87 for plasma specimens from 96 asbestos-exposed persons as compared with 48 patients with mesothelioma. CONCLUSIONS: Plasma fibulin-3 levels can distinguish healthy persons with exposure to asbestos from patients with mesothelioma. In conjunction with effusion fibulin-3 levels, plasma fibulin-3 levels can further differentiate mesothelioma effusions from other malignant and benign effusions.

Real-World Neoadjuvant Treatment Patterns and Outcomes in Resected Non-Small-Cell Lung Cancer.

BACKGROUND: Novel neoadjuvant chemoimmunotherapy treatments are being investigated for locally advanced non-small-cell lung cancer (NSCLC), but real-world outcomes for neoadjuvant treatments are poorly understood. This study examined neoadjuvant treatment patterns, real-world event-free survival (rwEFS) and overall survival (OS) in patients with resected, stage II-III NSCLC in the United States (US). METHODS: This retrospective study identified patients in the SEER-Medicare database (2007-2019) with newly diagnosed stage II, IIIA, and IIIB (N2) NSCLC (AJCC 8th edition) treated with neoadjuvant chemo/chemoradiotherapy and resection (index date: neoadjuvant therapy initiation). Neoadjuvant treatment regimens were described. rwEFS (time from index to first recurrence or death, whichever occurred first) and OS (time from index to death) were summarized by Kaplan-Meier analysis for overall population, by disease stage at diagnosis, and by neoadjuvant treatment modality. RESULTS: 221 patients (stage II, N=70; stage III, N=151) met eligibility criteria. The median follow-up from index was 32.7 months. All patients received neoadjuvant chemotherapy (51%) or chemoradiotherapy (49%) prior to surgery; 97% of patients received platinum-based regimens, among which carboplatin+paclitaxel was the most frequent (45%). In all patients, median rwEFS was 17.6 months and 5-year rwEFS was 20.9%; median OS was 48.5 months and 5-year OS was 44.9%. 71% of patients had disease recurrence during follow-up; among them, 28% developed locoregional recurrence as the first recurrence event. CONCLUSIONS: Patients with resected, stage II-III NSCLC who received neoadjuvant chemo/chemoradiotherapy have high rates of disease recurrence and poor survival outcomes, highlighting need for more effective treatments to improve survival rates.

Pack-Year Smoking History: An Inadequate and Biased Measure to Determine Lung Cancer Screening Eligibility.

PURPOSE: Pack-year smoking history is an imperfect and biased measure of cumulative tobacco exposure. The use of pack-year smoking history to determine lung cancer screening eligibility in the current US Preventive Services Task Force (USPSTF) guideline may unintentionally exclude many high-risk individuals, especially those from racial and ethnic minority groups. It is unclear whether using a smoking duration cutoff instead of a smoking pack-year cutoff would improve the selection of individuals for screening. METHODS: We analyzed 49,703 individuals with a smoking history from the Southern Community Cohort Study (SCCS) and 22,126 individuals with a smoking history from the Black Women's Health Study (BWHS) to assess eligibility for screening under the USPSTF guideline versus a proposed guideline that replaces the ≥20-pack-year criterion with a ≥20-year smoking duration criterion. RESULTS: Under the USPSTF guideline, only 57.6% of Black patients with lung cancer in the SCCS would have qualified for screening, whereas a significantly higher percentage of White patients with lung cancer (74.0%) would have qualified (P < .001). Under the proposed guideline, the percentage of Black and White patients with lung cancer who would have qualified for screening increased to 85.3% and 82.0%, respectively, eradicating the disparity in screening eligibility between the groups. In the BWHS, using a 20-year smoking duration cutoff instead of a 20-pack-year cutoff increased the percentage of Black women with lung cancer who would have qualified for screening from 42.5% to 63.8%. CONCLUSION: Use of a 20-year smoking duration cutoff instead of a 20-pack-year cutoff greatly increases the proportion of patients with lung cancer who would qualify for screening and eliminates the racial disparity in screening eligibility between Black versus White individuals; smoking duration has the added benefit of being easier to calculate and being a more precise assessment of smoking exposure compared with pack-year smoking history.

American Radium Society Appropriate Use Criteria for Unresectable Locally Advanced Non-Small Cell Lung Cancer.

Importance: The treatment of locally advanced non-small cell lung cancer (LA-NSCLC) has been informed by more than 5 decades of clinical trials and other relevant literature. However, controversies remain regarding the application of various radiation and systemic therapies in commonly encountered clinical scenarios. Objective: To develop case-referenced consensus and evidence-based guidelines to inform clinical practice in unresectable LA-NSCLC. Evidence Review: The American Radium Society (ARS) Appropriate Use Criteria (AUC) Thoracic Committee guideline is an evidence-based consensus document assessing various clinical scenarios associated with LA-NSCLC. A systematic review of the literature with evidence ratings was conducted to inform the appropriateness of treatment recommendations by the ARS AUC Thoracic Committee for the management of unresectable LA-NSCLC. Findings: Treatment appropriateness of a variety of LA-NSCLC scenarios was assessed by a consensus-based modified Delphi approach using a range of 3 points to 9 points to denote consensus agreement. Committee recommendations were vetted by the ARS AUC Executive Committee and a 2-week public comment period before official approval and adoption. Standard of care management of good prognosis LA-NSCLC consists of combined concurrent radical (60-70 Gy) platinum-based chemoradiation followed by consolidation durvalumab immunotherapy (for patients without progression). Planning and delivery of locally advanced lung cancer radiotherapy usually should be performed using intensity-modulated radiotherapy techniques. A variety of palliative and radical fractionation schedules are available to treat patients with poor performance and/or pulmonary status. The salvage therapy for a local recurrence after successful primary management is complex and likely requires both multidisciplinary input and shared decision-making with the patient. Conclusions and Relevance: Evidence-based guidance on the management of various unresectable LA-NSCLC scenarios is provided by the ARS AUC to optimize multidisciplinary patient care for this challenging patient population.

American Radium Society™ Appropriate Use Criteria on Cardiac Toxicity Prevention and Management After Thoracic Radiotherapy.

PURPOSE: The multidisciplinary American Radium Society (ARS) Thoracic Committee was assigned to create Appropriate Use Criteria (AUC) on cardiac toxicity prevention and management for patients undergoing radiotherapy. METHODS AND MATERIALS: A systematic review of the current literature was conducted. Case variants of patients with thoracic malignancies undergoing radiation were created based on presence or absence cardiovascular risk factors and treatment-related risks assessed by dose exposure to the heart/cardiac substructures. Modified Delphi methodology was used by to evaluate the variants and procedures, with ≤3 rating points from median defining agreement/consensus. RESULTS: 6 variants were evaluated. The panel felt patients with cardiac comorbidities at high risk for radiation-related cardiac toxicity should undergo a prescreening cardiac focused history and physical (H&P) exam, electrocardiogram (EKG), cardiac imaging including an echocardiogram, and referral to a cardiologist/cardio-oncologist. Recommendations for those without cardiac comorbidities at low risk for cardiac toxicity were to undergo a baseline history and physical examination only. Conversely, those without cardiac comorbidities but at high risk for radiation-related cardiac toxicity were recommended to undergo a prescreening EKG, in addition to a H&P exam. For patients with cardiac comorbidities at low risk for cardiac toxicity, the panel felt prescreening and post-screening tests may be appropriate. CONCLUSIONS: The ARS Thoracic AUC panel has developed multidisciplinary consensus guidelines for cardiac toxicity prevention, surveillance, and management after thoracic radiotherapy based on cardiac comorbidities at presentation and risk of radiation-related cardiac toxicity.

Appropriate Use Criteria (AUC) for Non-Small Cell Lung Cancer in a Central/Ultra-Central Location: Executive Summary of the American Radium Society's Systematic Review and Guidelines.

INTRODUCTION: Definitive radiation therapy is considered standard therapy for medically inoperable early-stage NSCLC. Nevertheless, for patients with tumors located near structures such as the proximal tracheobronchial tree, esophagus, heart, spinal cord, and brachial plexus, the optimal management regimen is controversial. The objective was to develop expert multidisciplinary consensus guidelines on managing medically inoperable NSCLC located in a central or ultracentral location relative to critical organs at risk. METHODS: Case variants regarding centrally and ultracentrally located lung tumors were developed by the 15-member multidisciplinary American Radium Society (ARS) Thoracic Appropriate Use Criteria (AUC) expert panel. A comprehensive review of the English medical literature was performed from January 1 1946 to December 31 2023 to inform consensus guidelines. Modified Delphi methods were used by the panel to evaluate the variants and procedures, with at least three rating points from median defining agreement/consensus. The guideline was then approved by the ARS Executive Committee and released for public comment per established ARS procedures. RESULTS: The Thoracic ARS AUC Panel identified 90 relevant references and obtained consensus in all variants. Radiotherapy alone was considered appropriate, with additional immunotherapy to be considered primarily in the clinical trial setting. Hypofractionated radiotherapy in eight to 18 fractions was considered appropriate for ultracentral lesions near the proximal tracheobronchial tree, upper trachea, and esophagus. For other ultracentral lesions near the heart, great vessels, brachial plexus, and spine, or for non-ultracentral but still central lesions, five-fraction stereotactic body radiation therapy was also considered an appropriate option. Intensity-modulated radiotherapy was considered appropriate and three-dimensional-conformal radiotherapy inappropriate for all variants. Other treatment planning techniques to decrease the risk of overdosing critical organs at risk were also considered. CONCLUSIONS: The ARS Thoracic AUC panel has developed multidisciplinary consensus guidelines for various presentations of stage I NSCLC in a central or ultracentral location.

Current Management of Stage IIIA (N2) Non-Small-Cell Lung Cancer: Role of Perioperative Immunotherapy, and Tyrosine Kinase Inhibitors.

There have been numerous recent advances in the treatmetn of stage IIIA non-small cell lung cancer. The most significant involve the addition of targeted therapies adn immune checkpoint inhibitors into perioperative care. These exciting advances are improving survival in this challenging patient population, but some-decade old controveries around the definition of resectability, prognositic importance of tumor response to induction therapy, and the role of pneumonectomy persist.

Restructuring lung cancer care to accelerate diagnosis and treatment in patients vulnerable to healthcare disparities using an innovative care model.

The diagnosis and treatment of lung cancer is challenged by complex diagnostic pathways and fragmented care that can lead to disparities for vulnerable patients. Our model involved a multi-institutional, multidisciplinary conference to address the complexity of lung cancer care in vulnerable patient populations. The conference was conducted using a process adapted from the problem-solving method entitled FastTrack, pioneered by General Electric. Conference attendees established critical social determinants of health specific to lung cancer and designed a practical care model to accelerate diagnosis and treatment in this population. The resulting care delivery model, the Lung Cancer Strategist Program (LCSP), was led by a lung cancer trained advanced practice provider (APP) to expedite diagnosis, surgical and oncologic consultation, and treatment of a suspicious lung nodule. We compared the timeliness of care, care efficiency, and oncologic outcomes in 100 LCSP patients and 100 routine referral patients at the same thoracic surgery clinic. Patient triage through our integrated care model transitioned initial referral evaluation to a lung cancer trained APP to coordinate multidisciplinary patient-centered care that was highly individualized and significantly reduced the time to diagnosis and treatment among vulnerable patients at high-risk for treatment delay due to healthcare disparities.•To develop the Lung Cancer Strategist Program care model, we used a three-step (Design, Meeting, and Culmination), team-based, problem-solving process entitled FastTrack.•An advantage of FastTrack is its ability to overcome barriers embedded within hierarchal and institutional social systems, empowering those closest to the relevant issue to propose and enact meaningful change.•Under this framework, we engaged a diverse field of experts to assess systemic barriers in lung cancer care and design an innovative care pathway to improve the timeliness and efficiency of lung cancer care in patients at risk for healthcare disparities.
