AI Article Synopsis

  • The study examines the impact of a dedicated pleural clinic (PC) on patient outcomes related to indwelling pleural catheters (IPCs), which help manage recurrent pleural effusions.
  • Patients from a retrospective study (2015-2021) showed increases in IPC placements and significant reductions in hospital admissions and procedures when managed by the PC.
  • Results indicated that the PC led to better patient outcomes, including a decrease in thoracenteses and higher rates of pleurodesis following IPC removal.

Article Abstract

Background: Recurrent pleural effusions are a major cause of morbidity and frequently lead to hospitalization. Indwelling pleural catheters (IPCs) are tunneled catheters that allow ambulatory intermittent drainage of pleural fluid without repeated thoracentesis. Despite the efficacy and safety of IPCs, data supporting postplacement follow-up is limited and variable. Our study aims to characterize the impact of a dedicated pleural clinic (PC) on patient outcomes as they relate to IPCs.

Methods: Patients who underwent IPC placement between 2015 and 2021 were included in this retrospective study. Differences in outcomes were analyzed between patients with an IPC placed and managed by Interventional Pulmonology (IP) through the PC and those placed by non-IP services (non-PC providers) before and after the PC implementation.

Results: In total, 371 patients received IPCs. Since the implementation of the PC, there was an increase in ambulatory IPC placement (31/133 pre-PC vs. 96/238 post-PC; P =0.001). There were fewer admissions before IPC placement (18/103 vs. 43/133; P =0.01), and fewer thoracenteses per patient (2.7±2.5 in PC cohort vs. 4±5.1 in non-PC cohort; P <0.01). The frequency of pleurodesis was higher in the PC cohort (40/103 vs. 41/268; P <0.001). A Fine and Gray competing risks model indicated higher likelihood of pleurodesis in the PC cohort (adjusted subhazard ratio 3.8, 95% CI: 2.5-5.87).

Conclusion: Our experience suggests that the implementation of a dedicated PC can lead to improved patient outcomes including fewer procedures and admissions before IPC placement, and increased rates of pleurodesis with IPC removal.

The growing complexity of care and healthcare workforce shortages in the Netherlands necessitates exploring interprofessional collaboration (IPC). However, the predominant single-professional education may result in a professional identity (PI) among healthcare students, which may not support successful IPC. Internships in student-run interprofessional learning wards (SR-IPLW) could foster interprofessional identity (IPI) development.

Rapid Pleurodesis in Patients With Chronic Noninfectious Pleural Effusion: Twenty Years of Real-world Performance Data.

J Bronchology Interv Pulmonol

January 2025

Division of Thoracic Surgery and Interventional Pulmonology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA.

Background: Small cohort studies have shown rapid pleurodesis protocol's (RPP) effectiveness and capacity to expedite pleurodesis for malignant pleural effusion (MPE). This study intends to evaluate the effectiveness of the RPP in inducing pleurodesis in patients with pleural effusions from either malignant or benign etiologies.

Methods: In this single-center, retrospective cohort study spanning 2 decades, we assessed patients with recurrent symptomatic chronic noninfectious pleural effusion, both benign and malignant.

  • Iliac vein stenting is the main treatment for iliac vein compression syndrome, but complications like restenosis and thrombosis can occur, and the effects of lower limb movements on stent function are not well understood.
  • This study developed a patient-specific computational model to analyze how different lower extremity exercises affect blood flow dynamics in the treated vein after stenting.
  • Results showed that hip flexion can disrupt blood flow and increase thrombosis risk, while exercises like active ankle movements and pneumatic compression may help improve blood flow and reduce complications.

  • - The study assessed radiography students' training and understanding of infection prevention and control (IPC) protocols related to using contrast media injectors in computed tomography (CT) through an online survey conducted at two Australian universities.
  • - Results showed that while most students received adequate training, only 65% displayed strong IPC knowledge, with significant confusion about the necessity of hand hygiene and risks associated with CT contrast tubing.
  • - The findings indicate a need for improved collaboration between academic institutions and clinical training sites to enhance IPC education and integrate better practices into students' training programs.
