Patient-Based Costing in Belgian Hospitals: Building ABC and TDABC from MZG/RHM and FINHOSTA - To Be
Introduction Patient-based costing seeks to measure the cost of care at the level of the individual patient rather than by broad departmental or specialty averages. In methodological terms, activity-based costing (ABC) assigns costs to activities and then to cost objects through cost drivers, whereas time-driven activity-based costing (TDABC) simplifies this logic by combining two core parameters: the cost of supplying resource capacity and the time required to perform the activities in the care process. In healthcare, TDABC has become especially relevant because it is explicitly tied to process mapping and the measurement of real care delivery across pathways. For Belgian hospitals, the policy relevance of patient-level costing is unusually high. Belgium still allocates a major part of hospital financing through an APR-DRG/SOI-based budget allocation whose weights are based on average length of stay (LOS) rather than cost weights. The Belgian Health Care Knowledge Centre (KCE) has...
