Exploring cost changes with time-driven activity-based costing after service delivery redesign in Dutch maternity care

Résumé fourni par la source

The implementation of Value-Based Healthcare (VBHC) has spread across international healthcare systems, aiming to improve decision-making by combining information about patient outcomes and costs of care. Time-Driven Activity-Based Costing (TDABC) is introduced as a pragmatic yet accurate method to calculate costs of care pathways. It is often applied to demonstrate value-improving opportunities, such as interventions aimed at service delivery redesign. It is imperative for healthcare managers to know whether these interventions yield the expected outcome of improving patient value, for which TDABC is also suitable. However, its application becomes more complex and labour intensive if the intervention extends beyond activity-level changes in existing care pathways, to the implementation of entirely new care pathways. The complexity arises from the potential influence of such interventions on the costs of related care pathways. To fully comprehend the impact of such interventions on organizational costs, it is important to include these factors in the cost calculation. Given the substantial effort required for this analysis, this may explain the limited number of prior TDABC studies with similar objectives. This methodological development paper addresses this gap by offering a pragmatic enrichment of the TDABC methodology. This enrichment is twofold. First, it provides guidance on calculating a change in costs without the need for a total cost calculation. Second, to secure granularity, a more detailed level of cost-allocation is proposed. The aim is to encourage further application of TDABC to conduct financial evaluations of promising interventions in the domain of VBHC and service delivery redesign.
