The possibility to translate into chart the results, immediately after obtaining the responses, transform, this evaluation in a diagnostic tool to use in routine clinical practice. The Knowledge Management Systems (KMS) applied in this context, let you create and store knowledge and guide the therapeutic decision. This article the routine QdVRS evaluation whit KMS. Describes the importance of a detailed analysis to identify requirements that lead to the development of an implementation model that enables to convert tacit knowledge into explicit knowledge, which it does not affect the normal functioning of health facilities and to promote the optimization of the QoL cancer patient.
