Analysis of micro-costing through the Time-Driven Activity-Based Costing (TDABC) method in viscosupplementation procedures in different application regimens

Objective: To evaluate the micro-costing of viscosupplementation procedures compared to different infiltration regimens. Methods: This study compared, through the Time-Driven Activity-Based Costing method, the micro-costing of these different application regimens using national cost averages as a basis for calculation in a medium-sized outpatient service. Results: The results demonstrated that the difference in costs with the single application is 31.47% less for three and 119.13% for five applications. Conclusions: No study showed a superiority of the five-application regimen over the three-application regimen, which leads one to believe that there is no justification for this procedure from an economic or quality-of-life point of view.
