[Towards congruence in nursing information provision in The Netherlands].

Few reliable data are available about nursing care in the Netherlands, whereas pressure from society to support the contributions of the discipline of nursing to health care delivery increases. This paper presents an information model to support analytical access to nursing labour and services. This model, the nursing information reference model (Dutch acronym 'VIRM') focuses on the structure to achieve congruence between data from the primary process of nursing care and data derived from that process for clinical practice, management, research, and policy purposes. The model is based on the 'collect-once/use-often' principle of data collection and management, which emphasizes single collection and registration through the patient record for multiple subsequent uses and purposes. In this paper core elements of the VIRM are being discussed. Determination of data from the primary process of nursing care to be provided for certain aims is currently being conducted by the Dutch Nursing Minimum Data Set (VMDNS) initiative. The article at issue should be understood as a starting point in the discussion about the development of a Nursing Minimum Data Set in the Netherlands.
