Development of nursing documentation system is the first step as a way to do nursing effectiveness research and proving effectiveness of nursing care on patient outcomes to the other health care professionals as well as the public.

To develop nursing documentation system using nursing process model, the system incorporated standardized nursing terminologies of North American Nursing Diagnosis Association(NANDA), Nursing Interventions Classification(NIC), and Nursing Outcomes Classification(NOC). The system was developed under the hospital information system by TCP/IP protocol and used Oracle as DBMS under the Windows 98 environment. Power Builder 5.0 was used as a program language.

First data model was created and served as the foundation for designing the user interface. And then the system was developed for collecting, storing, and retrieving nursing diagnoses, interventions, and outcomes and comparing the changes in patient outcomes before and after interventions performed.

By developing nursing information system that includes nursing care sensitive patient outcomes, nurses can involve nursing effectiveness research and know how to improve nursing care quality provided for patients by analyzing patient outcome data. Further evaluation of this system should be followed.
