Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Despite success at relieving dyspnea, there are problems with the long-term placement of TPC's. One risk is infection which is estimated at 5%. Furthermore, each drainage kit costs approximately $100 and is often paid out-of-pocket by patients. Over time, this may create a substantial cost burden. Finally, most patients who undergo TPC placement require home drainage by visiting nurses. This is a significant resource utilization and it often requires interruption of a patient's home routines via the visitation requirements.
Occasionally, the effusion no longer reaccumulates following TPC placement. In malignant effusions, this pleurodesis (see below) occurs up to 50% of the time in malignant effusions. When pleurodesis occurs, the TPC may be removed by a simple office procedure.
Pleurodesis, or the act of inducing scarring and obliteration of the potential space between the visceral and parietal pleura where pleural effusions develop, is a different mechanism of providing relief of dyspnea. In the USA in particular, the most common agent used for pleurodesis (talc) is associated with complications such as respiratory failure and adult respiratory distress syndrome (ARDS), a life-threatening condition. Talc is also very expensive.
Povidone-Iodine, an agent used for pleurodesis in many other countries, has been shown to be highly efficacious when given via other modalities. Studies report a pleurodesis rate of 90+% with Povidone-Iodine. It also has a favorable safety record and is inexpensive.
Given all of these factors, the investigators propose a prospective study using Povidone-Iodine at the time of TPC placement to promote pleurodesis. The investigators hypothesize that pleurodesis will occur quickly and frequently, thus enabling removal of the TPC, thereby saving cost, risks of infection, all while improving patients quality of life.
The investigators plan on doing this by enrolling patients prospectively who are to undergo TPC placement as part of their standard care. These patients would be prospectively enrolled and randomized to receive either usual care (no pleurodesis) or the investigational medication (povidone-iodine) intrapleurally at time of procedure. The investigators would subdivide groups prospectively between patients who have malignant pleural effusions and those who have benign (non-malignant) pleural effusions.
Following TPC placement and medication administration (if necessary), nursing and investigative physicians would then immediately follow them in the recovery area (to monitor for any negative immediate outcomes such as hypertension, hypotension, reactions, or significant pain) and in clinic as per their usual care (starting 1-2 weeks after discharge and as long as necessary). The investigators would monitor them for the outcomes as noted elsewhere.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Malignant Effusion - Usual Care
Patients who had a pleural effusion secondary to a malignant etiology and subsequently underwent tunneled pleural catheter (TPC) placement and had usual care during and afterwards. Usual care is the TPC only with no intrapleural medications. They would have nursing care in the recovery area afterwards and home nursing three times weekly.
No interventions assigned to this group
Malignant Effusion with Pleurodesis
Patients who had a pleural effusion secondary to a malignant etiology and subsequently underwent tunneled pleural catheter (TPC) placement and had intrapleural Povidone-Iodine administered at time of placement (100mL of 2% solution). They would have nursing care in the recovery area afterwards and home nursing three times weekly.
Povidone-Iodine
Intrapleural administration of Povidone-Iodine
Benign Effusion - Usual Care
Patients who had a pleural effusion secondary to a benign etiology and subsequently underwent tunneled pleural catheter (TPC) placement and had usual care during and afterwards. Usual care is the TPC only with no intrapleural medications. They would have nursing care in the recovery area afterwards and home nursing three times weekly.
No interventions assigned to this group
Benign Effusion with Pleurodesis
Patients who had a pleural effusion secondary to a benign etiology and subsequently underwent tunneled pleural catheter (TPC) placement and had intrapleural Povidone-Iodine administered at time of placement (100mL of 2% solution). They would have nursing care in the recovery area afterwards and home nursing three times weekly.
