본 연구는 의사결정나무분석법을 이용하여 유두혼란 방지로모유량의 분비를 증가시키고 궁극적으로 모유수유를 증진시킬수 있는 대체수유에 대하여 간호사들을 대상으로 대체수유교육요구의 예측모형을 구축한 것이다. 의사결정나무분석법은 그결과가 나무구조에 의해 모형이 표현되기 때문에 분석의 정확도 보다는 분석과정의 설명이 필요한 경우에 더 유용하며 특히어떤 예측변수가 목표변수를 설명하는데 더 중요한지를 쉽게파악할 수 있다. 본 연구 결과 대상자의 81.1%가 대체수유교육을 요구하였고,대체수유교육요구에 가장 유의한 예측변수는 대체수유교육에대한 지불의도였다. 대체수유교육에 대해 지불의도가 있는 집단의 95.2%가 대체수유교육을 요구하였고, 지불의도가 없는집단에서는 대체수유에 대해 모른다고 답한 대상자의 88.7%가대체수유교육을 요구하였으며, 대체수유에 대해 알고 있다고대답한 집단 중에서는 34.5세 이하 집단의 76.8%가 대체수유교육을 요구하는 것으로 나타났다. 대체수유에 대해 알고 있으면서 나이가 많은 집단에서는 공식적인 대체수유교육을 받은경험이 있는 집단의 88.9%가 대체수유교육을 교유하였고, 대체수유교육을 받은 경험이 없는 집단의 73.3%는 교육을 요구하지 않았다. 이러한 결과를 볼 때 대체수유에 대해 모른다고 대답한 간호사들을 중심으로 대체수유교육이 실시되어야 하겠으나, 대체수유교육을 받았다고 하더라도 최신의 정보와 함께 정확한 대체수유교육이 필요함을 알 수 있다. 대체수유교육비를 지불할의도가 있는 간호사의 대부분이 대체수유교육을 적극적으로 요구하였으나 그렇지 않은 간호사가 전체의 76.0%이기 때문에보수교육 등을 통하여 대체수유교육을 시행하는 것이 필요하겠다. 마지막으로 대체수유로 인해 신생아에게 발생하는 건강문제 등과 관련하여 논란의 여지가 있으니 이를 명확하게 규명하고 대체수유의 효과를 검증할 수 있는 연구를 제언하며, 무엇보다 대체수유에 대한 과학적인 원리와 정확한 수행방법을 간호사들에게 교육하고 대체수유 수행을 위한 간호 인력의 확보를 제언하는 바이다.
Abstract
Purpose: One of the main reasons why mothers quit breast feeding is that the volume of breast milk is inadequate due to insufficiency in suckling. We believe suckling experience may be a factor affecting nipple confusion. So an alternative feeding method, namely cup, spoon, finger, or nasogastric tube feeding may be needed to prevent nipple confusion. The purpose of this study was to construct a predictive model for demand for alternative feeding education by nurses. Methods: A descriptive design with structured self-report questionnaires was used for this study. Data from 175 nurses working in hospitals in Busan were collected between April 1 and 15, 2009. Data were analyzed by decision tree method, one of the data mining techniques using SAS 9.1 and Enterprise Miner 4.3 program. Results: Of the nurses, 81.1% demanded alternative feeding education and 5 factors showed that most of them expressed intention to pay, desire to know about alternative feeding, age, and learning experience. From these results, the derived model is considered appropriative for explaining and predicting demand for alternative feeding education. Conclusion: This confirms that knowledge and compliance in alternative breast feeding for newborn babies should be correct and any inaccuracies or insufficient information should be supplemented.
