Case Management in Prevention of 30-Day Readmission in Post-Coronary Artery Bypass Graft Surgery.

PURPOSE OF STUDY: Thirty-day readmission is associated with increased morbidity and mortality among postoperative coronary artery bypass graft (CABG) surgery patients. Interventions such as case management and follow-up care may reduce 30-day readmission. The purpose of this article is to report a study on modifiable factors that may have significant implications for case management in the prevention of readmission after CABG surgery. PRIMARY PRACTICE SETTINGS: The study population included all the adult patients who underwent first-time CABG surgery from January 1, 2013, to January 1, 2016, from a Mid-South hospital. METHODOLOGY AND SAMPLE: A retrospective case-control study was employed to examine 1,712 patients who underwent CABG surgery. RESULTS: The results revealed that patients readmitted within 30 days had a significantly shorter length of stay (LOS) (6 days vs. 10 days; p < .0001), more days in intensive care unit (6 days vs. 4 days; p = .0391), and significantly higher diabetes/renal (4% vs. 1%), infection (17% vs. 2%), and respiratory-related diagnoses (10% vs. 1%; p < .0001). IMPLICATIONS FOR CASE MANAGEMENT PRACTICE: Among these factors, hospital LOS is a major factor that can be addressed through case management in addition to other modifiable risk factors. Understanding modifiable factors associated with higher readmission risk is crucial for effective intervention and case management planning.

Prospective Comparative Effectiveness Trial of Multidisciplinary Lung Cancer Care Within a Community-Based Health Care System.

PURPOSE: Multidisciplinary lung cancer care is assumed to improve care delivery by increasing transparency, objectivity, and shared decision making; however, there is a lack of high-level evidence demonstrating its benefits, especially in community-based health care systems. We used implementation and team science principles to establish a colocated multidisciplinary lung cancer clinic in a large community-based health care system and evaluated patient experience and outcomes within and outside this clinic. METHODS: We conducted a prospective frequency-matched comparative effectiveness study (ClinicalTrials.gov identifier: NCT02123797) evaluating the thoroughness of lung cancer staging, receipt of stage-appropriate treatment, and survival between patients receiving care in the multidisciplinary clinic and those receiving usual serial care. Target enrollment was 150 patients on the multidisciplinary arm and 300 on the serial care arm. We frequency-matched patients by clinical stage, performance status, insurance type, race, and age. RESULTS: A total of 526 patients were enrolled: 178 on the multidisciplinary arm and 348 on the serial care arm. After adjusting for other factors, multidisciplinary patients had significantly higher odds (odds ratio [OR]: 2.3 [95% CI, 1.5 to 3.4]) of trimodality staging compared with serial care. Patients on the multidisciplinary arm also had higher odds of receiving invasive stage confirmation (OR: 2.0 [95% CI, 1.4 to 3.1]) and mediastinal stage confirmation (OR: 1.9 [95% CI, 1.3 to 2.8]). Additionally, patients receiving multidisciplinary care were significantly more likely to receive stage-appropriate treatment (OR: 1.8 [95% CI, 1.1 to 3.0]). We found no significant difference in overall or progression-free survival between study arms. CONCLUSION: The multidisciplinary clinic delivered significant improvements in evidence-based quality care on multiple levels. Even in the absence of a demonstrable survival benefit, these findings provide a strong rationale for recommending this model of care.

Lung Cancer Diagnosed Through Screening, Lung Nodule, and Neither Program: A Prospective Observational Study of the Detecting Early Lung Cancer (DELUGE) in the Mississippi Delta Cohort.

PURPOSE: Lung cancer screening saves lives, but implementation is challenging. We evaluated two approaches to early lung cancer detection-low-dose computed tomography screening (LDCT) and program-based management of incidentally detected lung nodules. METHODS: A prospective observational study enrolled patients in the early detection programs. For context, we compared them with patients managed in a Multidisciplinary Care Program. We compared clinical stage distribution, surgical resection rates, 3- and 5-year survival rates, and eligibility for LDCT screening of patients diagnosed with lung cancer. RESULTS: From 2015 to May 2021, 22,886 patients were enrolled: 5,659 in LDCT, 15,461 in Lung Nodule, and 1,766 in Multidisciplinary Care. Of 150, 698, and 1,010 patients diagnosed with lung cancer in the respective programs, 61%, 60%, and 44% were diagnosed at clinical stage I or II, whereas 19%, 20%, and 29% were stage IV (P = .0005); 47%, 42%, and 32% had curative-intent surgery (P < .0001); aggregate 3-year overall survival rates were 80% (95% CI, 73 to 88) versus 64% (60 to 68) versus 49% (46 to 53); 5-year overall survival rates were 76% (67 to 87) versus 60% (56 to 65) versus 44% (40 to 48), respectively. Only 46% of 1,858 patients with lung cancer would have been deemed eligible for LDCT by US Preventive Services Task Force (USPSTF) 2013 criteria, and 54% by 2021 criteria. Even if all eligible patients by USPSTF 2021 criteria had been enrolled into LDCT, the Nodule Program would have detected 20% of the stage I-II lung cancer in the entire cohort. CONCLUSION: LDCT and Lung Nodule Programs are complementary, expanding access to early lung cancer detection and curative treatment to different-risk populations. Implementing Lung Nodule Programs may alleviate emerging disparities in access to early lung cancer detection.

The Relative Survival Impact of Guideline-Concordant Clinical Staging and Stage-Appropriate Treatment of Potentially Curable Non-Small Cell Lung Cancer.

BACKGROUND: Lung cancer management guidelines strive to improve outcomes. Theoretically, thorough staging promotes optimal treatment selection. We examined the association between guideline-concordant invasive mediastinal nodal staging, guideline-concordant treatment, and non-small cell lung cancer survival. RESEARCH QUESTION: What is the current practice of invasive mediastinal nodal staging for patients with lung cancer in a structured multidisciplinary care environment? Is guideline-concordant staging associated with guideline-concordant treatment? How do they relate to survival? STUDY DESIGN AND METHODS: We evaluated patients with nonmetastatic non-small cell lung cancer diagnosed from 2014 through 2019 in the Multidisciplinary Thoracic Oncology Program of the Baptist Cancer Center, Memphis, Tennessee. We examined patterns of mediastinal nodal staging and stage-stratified treatment, grouping patients into cohorts with guideline-concordant staging alone, guideline-concordant treatment alone, both, or neither. We evaluated overall survival with Kaplan-Meier curves and Cox proportional hazards models. RESULTS: Of 882 patients, 456 (52%) received any invasive mediastinal staging. Seventy-four percent received guideline-concordant staging; guideline-discordant staging decreased from 34% in 2014 to 18% in 2019 (P < .0001). Recipients of guideline-concordant staging were more likely to receive guideline-concordant treatment (83% vs 66%; P < .0001). Sixty-one percent received both guideline-concordant invasive mediastinal staging and guideline-concordant treatment; 13% received guideline-concordant staging alone; 17% received guideline-concordant treatment alone; and 9% received neither. Survival was greatest in patients who received both (adjusted hazard ratio [aHR], 0.41; 95% CI, 0.26-0.63), followed by those who received guideline-concordant treatment alone (aHR, 0.60; 95% CI, 0.36-0.99), and those who received guideline-concordant staging alone (aHR, 0.64; 95% CI, 0.37-1.09) compared with neither (P < .0001, log-rank test). INTERPRETATION: Levels of guideline-concordant staging were high, were rising, and were associated with guideline-concordant treatment selection in this multidisciplinary care cohort. Guideline-concordant staging and guideline-concordant treatment were complementary in their association with improved survival, supporting the connection between these two processes and lung cancer outcomes.

Impact of a Lymph Node Specimen Collection Kit on the Distribution and Survival Implications of the Proposed Revised Lung Cancer Residual Disease Classification: A Propensity-Matched Analysis.

IMPORTANCE: The International Association for the Study of Lung Cancer (IASLC) has proposed a revision of the residual disease (R-factor) classification, to R0, 'R-uncertain', R1 and R2. We previously demonstrated longer survival after surgical resection with a lymph node specimen collection kit, and now evaluate R-factor redistribution as the mechanism of its survival benefit. OBJECTIVE: We retrospectively evaluated surgical resections for lung cancer in the population-based observational 'Mid-South Quality of Surgical Resection' cohort from 2009-2019, including a full-cohort and propensity-score matched analysis. RESULTS: Of 3,505 resections, 34% were R0, 60% R-uncertain, and 6% R1 or R2. The R0 percentage increased from 9% in 2009 to 56% in 2019 (p < 0.0001). Kit cases were 66% R0 and 29% R-uncertain, compared to 14% R0 and 79% R-uncertain in non-kit cases (p < 0.0001). Compared with non-kit resections, kit resections had 12.3 times the adjusted odds of R0 versus R-uncertainty.Of 2,100 R-uncertain resections, kit cases had lower percentages of non-examination of lymph nodes, 1% vs. 14% (p < 0.0001) and non-examination of mediastinal lymph nodes, 8% vs. 35% (p < 0.0001). With the kit, more R-uncertain cases had examination of stations 7 (43% vs. 22%, p < 0.0001) and 10 (67% vs. 45%, p < 0.0001).The adjusted hazard ratio (aHR) for kit cases versus non-kit cases was 0.75 (confidence interval [CI]: 0.66-0.85, p < 0.0001). In 2,100 subjects with R-uncertain resections, kit cases had an aHR of 0.79 versus non-kit cases ([CI: 0.64-0.99], p=0.0384); however, in the 1,199 R0 resections the survival difference was not significant (aHR: 0.85[0.68-1.07], p = 0.17). CONCLUSIONS AND RELEVANCE: A lymph node kit increased overall survival by increasing R0, reducing the probability of R-uncertain resections, and diminishing extreme R-uncertainty.

Interest in Cessation Treatment Among People Who Smoke in a Community-Based Multidisciplinary Thoracic Oncology Program.

INTRODUCTION: To evaluate the need for tobacco cessation services within a multidisciplinary clinic (MDC), we surveyed patients on their smoking status, interest in quitting, and willingness to participate in a clinic-based cessation program. We further evaluated the association between interest in cessation or willingness to participate in a cessation program and overall survival (OS). METHODS: From 2014 to 2019, all new patients with lung cancer in the MDC at Baptist Cancer Center (Memphis, TN) were administered a social history questionnaire to evaluate their demographic characteristics, smoking status, tobacco dependence, interest in quitting, and willingness to participate in a cessation program. We used chi-square tests and logistic regression to compare characteristics of those who would participate to those who would not or were unsure and Kaplan-Meier curves and Cox regression to evaluate the association between cessation interest or willingness to quit and OS. RESULTS: Of 641 total respondents, the average age was 69 years (range: 32-95), 47% were men, 64% white, 34% black, and 17% college graduates. A total of 90% had ever smoked: 34% currently and 25% quit within the past year. Among the current smokers, 60% were very interested in quitting and 37% would participate in a cessation program. Willingness to participate in a cessation program was associated with greater interest in quitting (p < 0.0001), better OS (p = 0.02), and reduced hazard of death (hazard ratio = 0.52, 95% confidence interval: 0.30-0.88), but no other characteristics. CONCLUSIONS: Patients with lung cancer in an MDC expressed considerable interest in tobacco cessation services; patients willing to participate in a clinic-based cessation program had improved survival.

Survival Impact of an Enhanced Multidisciplinary Thoracic Oncology Conference in a Regional Community Health Care System.

INTRODUCTION: We compared NSCLC treatment and survival within and outside a multidisciplinary model of care from a large community health care system. METHODS: We implemented a rigorously benchmarked "enhanced" Multidisciplinary Thoracic Oncology Conference (eMTOC) and used Tumor Registry data (2011-2017) to evaluate guideline-concordant care. Because eMTOC was located in metropolitan Memphis, we separated non-MTOC patient by metropolitan and regional location. We categorized National Comprehensive Cancer Network guideline-concordant treatment as "preferred," or "appropriate" (allowable under certain circumstances). We compared demographic and clinical characteristics across cohorts using chi-square tests and survival using Cox regression, adjusted for multiple testing. We also performed propensity-matched and adjusted survival analyses. RESULTS: Of 6259 patients, 14% were in eMTOC, 55% metropolitan non-MTOC, and 31% regional non-MTOC cohorts. eMTOC had the highest rates of African Americans (34% versus 28% versus 22%), stages I to IIIB (63 versus 40 versus 50), urban residents (81 versus 78 versus 20), stage-preferred treatment (66 versus 57 versus 48), guideline-concordant treatment (78 versus 70 versus 63), and lowest percentage of nontreatment (6 versus 21 versus 28); all p values were less than 0.001. Compared with eMTOC, hazard for death was higher in metropolitan (1.5, 95% confidence interval: 1.4-1.7) and regional (1.7, 1.5-1.9) non-MTOC; hazards were higher in regional non-MTOC versus metropolitan (1.1, 1.0-1.2); all p values were less than 0.05 after adjustment. Results were generally similar after propensity analysis with and without adjusting for guideline-concordant treatment. CONCLUSIONS: Multidisciplinary NSCLC care planning was associated with significantly higher rates of guideline-concordant care and survival, providing evidence for rigorous implementation of this model of care.

Trends in Accuracy and Comprehensiveness of Pathology Reports for Resected NSCLC in a High Mortality Area of the United States.

INTRODUCTION: Complete and accurate pathology reports are vital to postoperative prognostication and management. We evaluated the impact of three interventions across a diverse group of hospitals on pathology reports of postresection NSCLC. METHODS: We evaluated pathology reports for patients who underwent curative-intent surgical resection for NSCLC, at 11 institutions within four contiguous Dartmouth Hospital Referral Regions in Arkansas, Mississippi, and Tennessee from 2004 to 2020, for completeness and accuracy, before and after the following three quality improvement interventions: education (feedback to heighten awareness); synoptic reporting; and a lymph node specimen collection kit. We compared the proportion of pathology reports with the six most important items for postoperative management (specimen type, tumor size, histologic type, pathologic [p] T-category, pN-category, margin status) across the following six patient cohorts: preintervention control, postintervention with four different combinations of interventions, and a contemporaneous nonintervention external control. RESULTS: In the postintervention era, the odds of reporting all key items were eight times higher than those in the preintervention era (OR = 8.3, 95 % confidence interval [CI]: 6.7-10.2, p < 0.0001). There were sixfold and eightfold increases in the odds of accurate pT- and pN-category reporting in the postintervention era compared with the preintervention era (pT OR = 5.7, 95 % CI: 4.7-6.9; pN OR = 8.0, 95 % CI: 6.5-10.0, both p < 0.0001). Within the intervention groups, the odds of reporting all six key items, accurate pT category, and accurate pN-category were highest in patients who received all three interventions. CONCLUSIONS: Gaps in the quality of NSCLC pathologic reportage can be identified, quantified, and corrected by rationally designed interventions.

Outcomes After Use of a Lymph Node Collection Kit for Lung Cancer Surgery: A Pragmatic, Population-Based, Multi-Institutional, Staggered Implementation Study.

INTRODUCTION: Suboptimal pathologic nodal staging prevails after curative-intent resection of lung cancer. We evaluated the impact of a lymph node specimen collection kit on lung cancer surgery outcomes in a prospective, population-based, staggered implementation study. METHODS: From January 1, 2014, to August 28, 2018, we implemented the kit in three homogeneous institutional cohorts involving 11 eligible hospitals from four contiguous hospital referral regions. Our primary outcome was pathologic nodal staging quality, defined by the following evidence-based measures: the number of lymph nodes or stations examined, proportions with poor-quality markers such as nonexamination of lymph nodes, and aggregate quality benchmarks including the National Comprehensive Cancer Network criteria. Additional outcomes included perioperative complications, health care utilization, and overall survival. RESULTS: Of 1492 participants, 56% had resection with the kit and 44% without. Pathologic nodal staging quality was significantly higher in the kit cases: 0.2% of kit cases versus 9.8% of nonkit cases had no lymph nodes examined; 3.2% versus 25.3% had no mediastinal lymph nodes; 75% versus 26% attained the National Comprehensive Cancer Network criteria (p < 0.0001 for all comparisons). Kit cases revealed no difference in perioperative complications or health care utilization except for significantly shorter duration of surgery, lower proportions with atelectasis, and slightly higher use of blood transfusion. Resection with the kit was associated with a lower hazard of death (crude, 0.78 [95% confidence interval: 0.61-0.99]; adjusted 0.85 [0.71-1.02]). CONCLUSIONS: Lung cancer surgery with a lymph node collection kit significantly improved pathologic nodal staging quality, with a trend toward survival improvement, without excessive perioperative morbidity or mortality.

The International Association for the Study of Lung Cancer Global Survey on Molecular Testing in Lung Cancer.

INTRODUCTION: Access to targeted therapies for lung cancer depends on the accurate identification of patients' biomarkers through molecular testing. The International Association for the Study of Lung Cancer (IASLC) conducted an international survey to evaluate perceptions on current practice and barriers to implementation of molecular testing. METHODS: We distributed the survey to IASLC members and other health care professionals around the world. The survey included a seven-question introduction for all respondents, who then answered according to one of three tracks: (1) requesting tests and treating patients, (2) performing and interpreting assays, or (3) tissue acquisition. Barriers to implementing molecular testing were provided in free-response fields. The chi-square test was used for regional comparisons. RESULTS: A total of 2537 respondents from 102 countries participated. Most respondents who test and treat patients believe that less than 50% of patients with lung cancer in their country receive molecular testing, but reported higher rates within their own practice. Although many results varied by region, the five most frequent barriers cited in all regions were cost, quality and standards, access, awareness, and turnaround time. Many respondents expressed dissatisfaction with the current state of molecular testing for lung cancer, including 41% of those performing and interpreting assays. Issues identified included trouble understanding results (37%) and the quality of the samples (23% reported >10% rejection rate). Despite concerns regarding the quality of testing, 47% in the performing and interpreting track stated there is no policy or strategy to improve quality in their country. In addition, 33% of respondents who request tests and treat patients were unaware of the most recent College of American Pathologists, IASLC, and Association for Molecular Pathology guidelines for molecular testing. CONCLUSIONS: Adoption of molecular testing for lung cancer is relatively low across the world. Barriers include cost, access, quality, turnaround time, and lack of awareness.

Outcomes of Capecitabine and Temozolomide (CAPTEM) in Advanced Neuroendocrine Neoplasms (NENs).

Capecitabine and temozolomide (CAPTEM) have shown promising results in the treatment of neuroendocrine neoplasms (NEN). The aim of this study was to evaluate the outcome and role for CAPTEM in malignant neuroendocrine neoplasms. Data were obtained from NEN patients who received at least one cycle of CAPTEM between November 2010 and June 2018. The average number of cycles was 9.5. For analysis, 116 patients were included, of which 105 patients (91%) underwent prior treatment. Median progression free survival (PFS) and overall survival (OS) were 13 and 38 months, respectively. Overall response rate (ORR) was 21%. Disease control rate (DCR) was 73% in all patients. PFS, median OS, ORR, and DCR for pancreatic NENs (pNEN) vs. non-pNEN was 29 vs. 11 months, 35 vs. 38 months, 38% vs. 9%, and 77% vs. 71%, respectively. Patients with pNEN had a 50% lower hazard of disease progression compared to those with non-pNEN (adjusted Hazard Ratio: 0.498, p = 0.0100). A significant difference in PFS was found between Ki-67 < 3%, Ki-67 3-20%, Ki-67 > 20-54%, and Ki-67 ≥ 55% (29 vs. 12 vs. 7 vs. 5 months; p = 0.0287). Adverse events occurred in 74 patients (64%). Our results indicate that CAPTEM is associated with encouraging PFS, OS, and ORR data in patients with NENs.

A meta-analysis of toxicities related to hydroxycarbamide dosing strategies.

Due to fear of short-term toxicities, there is nonconsensus of hydroxycarbamide dosing strategy (escalated vs fixed-dosing methods), which contributes to its suboptimal use. We performed a meta-analysis to summarize the incidence rates of toxicities associated with both dosing methods. Summarized incidence rates could not be statistically compared between dosing methods due to sparse data. Summarized neutropenia and thrombocytopenia incidence rates were slightly higher when using escalated dosing than with fixed. Summarized reticulocytopenia was comparable. Summarized hepatic and renal toxicities' incidence rates were slightly higher when using fixed doses than with escalated. We recommend diligent and transparent reporting of toxicities.
