Time-Driven Activity-Based Costing in Interventional Oncology: Cost Measurement and Cost Variability for Hepatocellular Carcinoma Therapies

Purpose To use time-drive activity-based costing (TDABC) to characterize and compare costs of transarterial chemoembolization (TACE), transarterial radioembolization (TARE), and ablation. Methods This three-part study involved (1) prospective observation to record resources used during TACE, TARE, and ablation and statistical evaluation of interobserver and interprocedure variability; (2) Bland-Altman analysis of prospective measurements and...
