PURPOSE: The purpose of this study was to identify nursing interventions performed by public health nurses in health centers. METHOD: Data was collected by the taxonomy of Nursing Intervention Classification (NIC 3rd: 486 nursing interventions) from 131 public health nurses in health centers and analyzed using descriptive statistics. RESULT: As its result, more than 50% of public health nurses performed 137 nursing interventions at least monthly. The most frequently used intervention class was 'activity and exercise management', followed by 'physical comfort promotion', 'community health promotion', 'life span care', 'coping assistance', 'Self care facilitation', 'information management', 'nutrition support', 'community risk management' and 'patient education'. One hundred twenty nursing interventions were rarely performed by 90% or more of the nurses. Most of them were the physical complex domain. CONCLUSION: In conclusion, 137 interventions were performed by public health nurses at least monthly. NIC is helpful to build a standardized language for public health nursing.
