This article examines how multiprofessional healthcare teams, working as a post-New Public Management (post-NPM) reform, respond to accountability pressure resulting from the implementation of NPM reforms. The team members use three strategies to respond to this pressure: responsibility avoiding that results in conflict; responsibility ignoring that results in parallel work and responsibility sharing that results in cooperation. Depending on how the professionals respond to different contextual factors, the choice of strategies can either foster or inhibit cooperation in multiprofessional teams. Achieving holistic patient care is threatened when accountability pressure increases for teams that have not yet developed their internal routines of cooperation.
