Previously developed quality indicators (QIs) for the intensive care did not give clues for quality improvement. We will improve this by developing new QIs that are actionable, reliable, valid and easy to register. Using a modified RAND technique we developed in three rounds new QIs for blood use at Dutch intensive care units (ICUs). The final set of QIs will be part of the National Intensive Care Evaluation quality registry and evaluated in a randomized controlled trial. In addition, a web-based feedback tool containing strategies for quality improvement will be developed. With the results of this project we hope to improve and maintain good quality of care at the Dutch ICUs .
