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.

The purpose of this study was to develop and to apply the NANDA, NOC, and NIC (NNN) linkages into a computerized nursing process program using the classification systems of nursing diagnoses, nursing outcomes and nursing interventions.

The program was developed with planning, analysis, design and performance stages. The program was applied to 117 patients who were admitted to orthopedic surgery nursing units from January to February, 2004.

Thirty-five of fifty-three nursing diagnoses were identified. Five nursing diagnoses in order of frequency were: Acute pain (28.4%), Impaired physical mobility (15.6%), Impaired walking (8.7%), Chronic pain (5.5%) and Risk for disuse syndrome (5.0%). The nursing outcomes of the 'Acute pain' nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management (95.2%), Comfort level (35.5%) and Pain level (17.7%). The nursing interventions of the ‘Acute pain’ nursing diagnosis tended to have higher frequencies (cumulative) in order of Pain management (71.0%), Splinting (24.2%) and Analgesic administration (17.7%). In comparison of outcome indicator scores between before and after the intervention according to the 61 nursing outcomes, the mean scores of 52 outcome indicators after the intervention were significantly higher than before the intervention.

It is expected that this program will help nurses perform their nursing processes more efficiently.
