Management of malignant pleural effusion by an indwelling pleural catheter: A cost-efficiency analysis

Abstract

Background: For patients that are expected to survive for longer, the risk of complications combined with the need for more vacuum drainage bottles have become barriers to the placement of indwelling pleural catheter (IPC), since these could increase costs. Objetives: The objective of the current article is to determine the cost and efficiency of treating malignant pleural effusion (MPE) with IPC in Spanish hospitals. Methods: We compared the cost associated with the use of IPC per outpatient and per inpatient. We analyzed the number of consultations, length of hospital stay, and outcome of the procedure. Results: Fifty-five patients were recruited. Spontaneous pleurodesis was achieved in 34.4% of the cases. Post-catheterization complications were observed in 7.2%. Supplementary procedures were unnecessary and 87.7% of the patients reported improved dyspnea. In 64.9% of the cases, the IPCs were inserted during hospitalization with a median hospitalization time of 4 days (1-7.5). There were differences in the number of visits with more consultations being observed in the outpatient group. There was no difference in the number of vacuum drainage bottles used. The complications supposed a cost increase of €1045.6 per outpatient and €432.54 per inpatient. The overall average cost of treatment per outpatient was €3310.2 and €5450.3 per inpatient. Conclusions: The treatment with IPC was effective, safe, without need of any more procedures and led to improved dyspnea in more than 85% of the patients. The cost is lower in the outpatient group, although complications represent an increased cost in both groups.
