Abstract
This commentary discusses the study by Stadhouders et al, which analyzes budget reallocations among Dutch healthcare providers as a result of one form of active purchasing. The study assumes that healthcare purchasers aim to shift substantial funds from inefficient to efficient providers, yet finds little evidence of such shifts. This commentary explains more explicitly why substantial volume shifts are not and should not be a major factor in the Dutch context, citing factors such as the scarcity of underperforming providers, strong regional dependencies, data quality limitations, and patient reluctance to change provider. More promising avenues for active purchasing include fostering active collaboration and improving contractual arrangements.
