The purpose of this study was to identify nursing importance and the performance of nursing interventions linked to five nursing diagnoses and find out core nursing interventions to each of the five nursing diagnosis. The five nursing diagnoses were Pain, Diarrhea, Constipation, Hyperthermia, and Infection: Risk for.

Data was collected from nurses working in four different hospitals. Data were analyzed using mean, SD, and paired t-test to compare difference between importance and performance of each intervention.

In general interventions related to medication, such as Medication Administration: IV, Medication Administration: IM, Medication Administration: Oral, Medication Management were all considered highly important and performed very often regardless of nursing diagnoses. And the level of importance was higher than the performance in most of all the interventions linked to five nursing diagnoses. Only two interventions, Medication Administration and Intravenous (IV) insertion had higher level of performance than importance in the diagnoses of Pain and Diarrhea respectively.

Using the above findings, we now know which intervention should be performed more frequently to solve nursing problems and which interventions are more critically important to nursing diagnosis. This information can be very helpful for developing nursing information system.
