PURPOSE: To identify perceived importance and performance frequency of nursing interventions with nursing activities of 5 nursing interventions from the physiological domains of NIC used in the home health care nursing. METHOD: Five nursing interventions in the physiological domain of NIC were selected based on the previous finding. Data were collected from 85 nurses working in 54 home health care centers between August and October, 2004 using mailing survey(return rates : 41.5%). The questionnaire consisted of 96 nursing activities in 5 interventions with definitions, asking perceived importance and performance frequency of them. RESULT: Skin surveillance was perceived as the most important(3.52+/-0.36) intervention and also performed most frequently(4.43+/-0.45). All the nursing activities in skin surveillance appeared to be used frequently, which was rated over 4 out of 5 point Likert, while only 4 nursing activities in exercise therapy: joint mobility did. Correlations between perceived importance and performance frequency of 5 interventions were all significant (r=0.591-0.718, p=0.000). CONCLUSION: Identifying the use of particular interventions and nursing activities will help nurses simplify documentations and to deliver better care to the patients in home health care nursing.
