Resumen:
Objective: Using a hydrogel plug decreases the number of cases of pneumothorax and reduces the need for pleural drainage tubes in CT-guided lung biopsies. We aimed to analyze the costeffectiveness of using hydrogel plugs.
Material and methods: We analyzed 171 lung biopsies divided into three groups: Group 1 (n= 22): fine-needle aspiration cytology (FNAC) without hydrogel plugs; Group 2 (n=89): FNAC with hydrogel plugs; and Group 3 (n=60): FNAC plus core-needle biopsy (CNB) with hydrogel plugs. We calculated the total costs (direct and indirect) in the three groups. We analyzed the percentage of correct diagnoses, the average and incremental rations, and the most costeffective option.
Results: Total costs: Group 1= 1,261.28 + 52.65 = (sic)1,313.93; Group 2 =1,201.36+ 67.25 = (sic) 1,268.61; Group 3=1,220.22 + 47.20 = (sic) 1,267.42. Percentage of correct diagnoses: Group 1 = 77.3%, Group 2 = 85.4%, and Group 3 = 95% (p = 0.04). Average cost-effectiveness ratio: Group 1 = 16.99; Group 2 =14.85; and Group 3 = 13.34.
Conclusions: Group 3 was the best option, with the lowest average cost-effectiveness ratio; therefore, the most cost-effective approach is to do FNAC and CNB using a dehydrated hydrogel plug at the end of the procedure. (C) 2019 SERAM. Published by Elsevier Espana, S.L.U. All rights reserved.
