Lung volume reduction surgery: a micro-costing analysis from a national tertiary referral centre

Abstract

Abstract OBJECTIVES Lung volume reduction surgery (LVRS) is a clinically effective palliation procedure for patients with chronic obstructive pulmonary disease. LVRS has recently been commissioned by the NHS England. In this study, a costing model was developed to analyse cost and resource implications of different LVRS procedures. METHODS Three pathways were defined by their surgical procedures: bronchoscopic endobronchial valve insertion (EBV-LVRS), video-assisted thoracic surgery LVRS and robotic-assisted thoracic surgery LVRS. The costing model considered use of hospital resources from the LVRS decision until 90 days after hospital admission. The model was calibrated with data obtained from an observational study, electronic health records and expert opinion. Unit costs were obtained from the hospital finance department and reported in 2021 Euros. RESULTS Video-assisted thoracic surgery LVRS was associated with the lowest cost at €12 896 per patient. This compares to the costs of EBV-LVRS at €15 598 per patient and €13 305 per patient for robotic-assisted thoracic surgery LVRS. A large component of EBV-LVRS costs were accrued secondary to complications, including revision EBV-LVRS. CONCLUSIONS This study presents a comprehensive model framework for the analysis of hospital-related resource use and costs for the 3 surgical modalities. In the future, service commissioning agencies, hospital management and clinicians can use this framework to determine their modifiable resource use (composition of surgical teams, use of staff and consumables, planned length of stay and revision rates for EBV-LVRS) and to assess the potential cost implications of changes in these parameters.
