This is a methodological study and technological production that aims to describe the development of a computerized system of nursing care quality indicators for the Intensive Care Unit. The study population consisted of a systems analyst and fifteen critical care nurses. For the development of the system we adopted some of the best practices of the Unified Process methodology using the Unified Modeling Language and the programming language Java Enterprise Edition 7. The system consists of an access menu with the following functions: Home (presents general information), New Record (records the indicator), Record (record search), Census (add information and indicators of the patient), Report (generates report of the indicators) and Annex (accesses the Braden Scale). This information system allows for measurement of the quality of nursing care and to evaluate patient safety in intensive care unit by monitoring quality indicators in nursing.
