Safety and Outcomes of Outpatient Pleural Drainage in Symptomatic Postoperative Cardiac Surgery Patients.

BACKGROUND: Symptomatic pleural effusions and anticoagulant/antiplatelet medication use in postoperative cardiac surgery are common. Guidelines and recommendations are currently mixed regarding medication management related to invasive procedure performance. We aimed to describe the outcomes of postoperative cardiac surgery patients referred for outpatient, symptomatic pleural effusion management. METHODS: A retrospective study of post-cardiac surgery patients undergoing outpatient thoracentesis from 2016 to 2021 was performed. Demographics, operative details, pleural disease characteristics, outcomes, and complications were collected. Odds ratios with confidence intervals were estimated and adjusted by multivariate logistic regression to investigate the association with multiple thoracenteses. RESULTS: A total of 110 patients underwent 332 thoracenteses. The median age was 68 years and most common operation was coronary artery bypass. Anticoagulation or antiplatelet use was identified in 97%. Thirteen complications were identified, with all major complications (n=3) related to bleeding. The amount of fluid present at the time of initial thoracentesis (>1500 milliliters) was associated with increased odds ratio of subsequent multiple thoracentesis (Unadjusted odds ratio, 6.75 (CI - 1.43 to 31.9). No other variables had a significant association with the need for multiple procedures. CONCLUSION: Within a postoperative cardiac surgery population presenting with symptomatic pleural disease, we observed that thoracentesis performed on antiplatelet and/or anticoagulant medication is relatively safe. We also identified that many patients can be managed as outpatients and that most pleural effusions remain self-limited. The presence of larger amounts of pleural fluid at initial thoracentesis may be associated with increased odds for additional drainage.

Muscle mass cross-sectional area is associated with survival outcomes in malignant pleural disease related to lung cancer.

INTRODUCTION: Malignant pleural effusions are common in advanced malignancy and associated with overall poor survival. The presence of sarcopenia (decreased muscle mass) is associated with poor outcomes in numerous disease states, however, its relationship to malignant pleural disease has not been defined. We sought to understand if there was an association between decreased survival and decreased muscle mass in patients with malignant pleural effusion. METHODS: Patients with malignant pleural disease undergoing indwelling tunneled pleural catheter placement were retrospectively reviewed. Computed tomography was reviewed and cross-sectional area of pectoralis and paraspinous muscle areas were calculated. Overall survival and associations with muscle mass were calculated. RESULTS: A total of 309 patients were available for analysis, with a median age of 67 years and the majority female (58%). The median survival was 129 days from initial pleural drainage to death. Regression analysis and Kaplan-Meier survival analysis did not reveal an association with survival and muscle mass for the entire population. However, Kaplan-Meier survival analysis of the lung cancer subgroup revealed the presence of decreased muscle mass and decreased survival time. CONCLUSION: The presence of decreased muscle mass within a lung cancer population that has malignant pleural effusions are associated with decreased survival. However, the presence of decreased muscle mass within a heterogenous population of malignant pleural disease was not associated with decreased overall survival time. Further study of the role that sarcopenia may play in malignant pleural disease is warranted.

Utilization of palliative care resource remains low, consuming potentially avoidable hospital admissions in stage IV non-small cell lung cancer: a community-based retrospective review.

PURPOSE: Early referral of patients with stage IV non-small cell lung cancer (NSCLC) to outpatient palliative care has been shown to increase survival and reduce unnecessary healthcare resource utilization. We aimed to determine outpatient palliative care referral rate and subsequent resource utilization in patients with stage IV NSCLC in a multistate, community-based hospital network and identify rates and reasons for admissions within a local healthcare system of Washington State. METHODS: A retrospective chart review of a multistate hospital network and a local healthcare system. Patients were identified using ICD billing codes. In the multistate network, 2844 patients diagnosed with stage IV NSCLC between January 1, 2013, and March 1, 2018, were reviewed. In the state healthcare system, 283 patients between August 2014 and June 2017 were reviewed. RESULTS: Referral for outpatient palliative care was low: 8% (217/2844) in the multistate network and 11% (32/283) in the local healthcare system. Early outpatient palliative care (6%, 10/156) was associated with a lower proportion of patients admitted into the intensive care unit in the last 30 days of life compared to no outpatient palliative care (15%, 399/2627; p = 0.003). Outpatient palliative care referral was associated with improved overall survival in Kaplan Meier survival analysis. Within the local system, 51% (104/204) of admissions could have been managed in outpatient setting, and of the patients admitted in the last 30 days of life, 59% (87/147) experienced in-hospital deaths. CONCLUSION: We identified underutilization of outpatient palliative care services within stage IV NSCLC patients. Many patients with NSCLC experience hospitalization the last month of life and in-hospital death.

Comparing Initial Surgery versus Fibrinolytics for Pleural Space Infections: A Retrospective Multicenter Cohort Study.

Rationale: When drainage of complicated pleural space infections alone fails, there exists two strategies in surgery and dual agent-intrapleural fibrinolytic therapy; however, studies comparing these two management strategies are limited. Objectives: To determine the outcomes of surgery versus fibrinolytic therapy as the primary management for complicated pleural space infections (CPSI). Methods: A retrospective review of adults with a CPSI managed with surgery or fibrinolytics between 1/2015 and 3/2018 within a multicenter, multistate hospital system was performed. Fibrinolytics was defined as any dose of dual-agent fibrinolytic therapy and standard fibrinolytics as 5-6 doses twice daily. Treatment failure was defined as persistent infection with a pleural collection requiring intervention. Crossover was defined by any fibrinolytics after surgery or surgery after fibrinolytics. Logistic regression with inverse probability of treatment weighting (IPTW) were employed to account for selection bias effect of management strategies in treatment failure and crossover. Results: We identified 566 patients. Surgery was the initial strategy in 55% (311/566). The surgery group had less additional treatments (surgery: 10% [32/311] versus fibrinolytics: 39% [100/255], P < 0.001), treatment failures (surgery: 7% [22/311] versus fibrinolytics: 29% [74/255], P < 0.001), and crossovers (surgery: 6% [20/311] versus fibrinolytics: 19% [49/255], P < 0.001). Logistic regression analysis with IPTW demonstrated a lower odds of treatment failure with surgery compared with any fibrinolytics (odds ratio [OR], 0.20; 95% confidence interval [CI], 0.10-0.30; P < 0.001); and compared with standard fibrinolytics (OR, 0.20; 95% CI, 0.11-0.35; P < 0.001). Conclusions: Although there is a lack of consensus as to the optimal management strategy for patients with a CPSI, in surgical candidates, operative management may offer more benefits and could be considered early in the management course. However, our study is retrospective and nonrandomized; thus, prospective trials are needed to explore this further.
