The purpose of this study was to classify, from collected home health care records data, nursing diagnoses according to the NANDA system and nursing interventions according to the NIC system, and to link nursing interventions to nursing diagnoses. For this study, 101 home health care records of clients seen between September, 1994 and November, 1996 at Yonsei Medical Center, Seoul, were analyzed. The results of this study are summarized as follows: 1. The most frequent nursing diagnoses were 'Risk for infection' and 'Altered nutrition : Less than body requirements', then 'Impaired skin integrity' and 'Ineffective airway clearance' in the Exchange patterns of NANDA nine human response patterns. 2. The most frequent nursing interventions were the interventions in the Physiological : Complex domain, there were 690(50.7%) interventions among a total 1347 interventions. This results corresponds to Yom, Young Hee(1995)'s research, both Korean and U.S. nurses used the interventions in the Physiological : Complex domain most often on a daily basis. And respiratory nursing interventions were most frequent because 32.7% of the subjects were respiratory patients. 3. The next step was to link the nursing interventions to nursing diagnoses. The most frequent nursing diagnosis was 'Risk for infection' and 19 interventions for 'Risk for infection' were used 267 times. Then 14 interventions for 'Impaired skin integrity' were used 258 times, 12 interventions for 'Ineffective airway clearance' were used 193 times, 12 interventions for 'Altered nutrition : Less than body requirements' were used 122 times, 10 interventions for 'Activity intolerance' were used 75 times, and 11 interventions for 'Knowledge deficit' were used 52 times. 4. The use of standardized classification in the areas of nursing diagnoses and nursing interventions facilitates clinical decision making and prompt nursing activity, and so enhances the effectiveness of nursing care.
