Abstract

The purpose of this study is to explore the relationship between warfarin-related knowledge, self-efficacy, and medication adherence among patients who underwent heart valve replacement surgery. The patients who underwent heart valve surgery and warfarin therapy were included in this study. The data was collected by administering questionnaires, and the data was then analyzed using the SPSS WIN 22.0 program. There was a positive relationship between warfarin-related knowledge and the adherence to medication (r=.285, p=004). Medication adherence was also positively correlated with warfarin-related knowledge (r=.250, p=.046) and self-efficacy (r=.292, p=.019) for elderly patients under 70 years of age. Further, medication adherence of elderly patients over 70 years of age was correlated with only warfarin-related knowledge (r=.358, p=.032). The results of this study show that in order to improve medication adherence, elderly people should be provided with warfarin-related knowledge through individually tailored education and nursing interventions that strengthen self-efficacy, as well as the knowledge that is needed in the elderly group under 70 years old.

본 연구는 와파린 약물 관련 지식, 자기효능감, 약물복용이행도의 관계를 파악하여 와파린 약물복용이행도를 높일 수 있는 교육의 필요성을 강조하고 효율적인 맞춤형 간호중재 프로그램 개발에 도움이 되고자 시행하였다. 연구방법은 서술적 상관관계 연구로 2018년 2월 21일부터 9월 30일까지 20세 이상의 성인을 대상으로 심장판막 수술을 받고 와파린을 복용한지 6개월 이상 된 외래 통원치료 환자를 대상으로 이루어졌다. 연구결과 와파린 약물관련 지식과 약물복용이행도에서 유의한 상관관계(r=.285, p=.004)를 보였다. 70세 미만에서 약물복용이행도는 와파린 약물관련 지식(r=.250, p=.046)과 자기효능감(r=.292, p=.019)에서 각각 양의 상관관계를 보였고, 70세 이상에서 약물복용이행도는 와파린 약물관련 지식(r=.358, p=.032)과 유의한 양의 상관관계가 있었다. 또한 약물복용이행도의 차이에서 70세 미만(7.24±1.30)과 70세 이상(7.09±1.00)에서 연령과 상관없이 큰 차이가 없었는데, 이는 고령화에도 불구하고 약물복용이행이 비슷한 수준으로 잘 유지된 것으로 볼 수 있어 어떤 요소가 70세 이상의 고령 환자의 약물복용이행도를 높게 유지하는 지 후속연구가 필요하겠다. 따라서 약물복용이행도를 향상시키기 위해서는 간호 교육 측면으로 1:1개별 교육프로그램, 코칭 프로그램을 개발하고, 간호 연구 측면으로 각 분야의 다양한 전문가가 연계되어 와파린 복용 교육에 대한 연구가 필요하다. 또한 시각적 측면으로 약물 교육에 대한 멀티미디어 효과에 대한 연구를 제언한다.
