However, family caregivers burden has not been well recognized. The objectives of this study were to evaluate the level of caregivers burden and to explore the related factors based on family, patient, and social support factors. Methods: A face-to-face interview with 86 family caregivers who had been taking care of COPD patients was conducted. The participants answered a self-administered questionnaire. The questionnaire included the level of family caregivers burden, health status and the relationship within the family, functional limitation of patients perceived by family caregivers and the social support. Results: The level of caregivers burden among participants was considerably high. Risk factors for caregivers burden included low educational level of family caregivers, low family income, hours of caregiving, and functional limitation of the patients. Protective factors for caregivers burden were good relationship within the family and support from other family members or friends. Conclusion: It is proved that family caregivers are facing significant burden in taking care of COPD patients. To reduce family caregivers burden, it is necessary to address socioeconomic status of the family and to provide various community resources including financial support and nursing services.

COPD 의중증도가심해짐에따라독립적인생활에심각한영향을주기때문에 3,4 환자가일상생활을유지하기위해서는가족의돌봄이필수적이다. 따라서 COPD 는환자와상호관계에있는가족구성원에게도영향을미치게된다. COPD 환자를돌보는가족은환자에대한장기적인돌봄요구로인해신체적, 경제적, 사회적, 정서적인 434

Study model. 어려움, 즉보호부담을경험할것으로예상된다. 실제 COPD 환자가족들은 % 가우울증상을경험하는것으로알려져있고 5,6, Bergs 7 는 COPD 환자의아내를 숨겨진환자 (hidden patient) 라고명명하면서아내는기존역할에서환자돌봄역할이추가되면서우울, 분노, 만성피로, 에너지감소, 경제적스트레스를경험한다고보고하였다. 이러한가족의신체적, 정신적상태는다시환자의치료와재활에영향을미치기때문에가족의총체적인보호부담을살펴보는것은매우중요하다. 치매, 뇌졸중, 정신분열증등과같은만성병환자의보호부담은주로가족의인구사회학적및돌봄의특성, 환자의건강상태, 사회적지지와관련이있다 8. 돌봄시간, 환자의신체적의존성, 가족의부정적건강상태, 경제적어려움등의요인은보호부담을높이며사회적지지, 원만한가족관계등은보호부담을낮추는것으로알려져있다 하지만 COPD 환자가족들에대해서는보호부담을실증적으로분석한연구가드물며, 국내에서는전무한상황이다. COPD 환자가족들의보호부담의정도와가족보호부담과관련된요인들은무엇인지에대한분석은 COPD 환자가족의보호부담감소뿐만아니라환자의통합적치료전략을세우는데기초자료를제공할수있을것이다. 이에본연구에서는 COPD 환자가족들의보호부담수준을알아보고, 보호부담과가족요인, 환자요인, 사회적지지요인사이의관련성을살펴보고자하였다 (Figure 1). 대상및방법 1. 연구대상본연구는 2006년 10월 1일부터 2007년 6월 30일까지 경기지역소재 1개대학병원호흡기-알레르기내과에서입원혹은외래치료를받고있는 COPD 환자의가족보호자 86명을대상으로이루어졌다. 2. 연구방법 COPD 환자의진료를담당한의사의의뢰에의해사회복지사가 COPD 환자의가족보호자를 1 : 1면담형식으로설문조사를진행하였다. COPD의정의는 Global Initiative for Chronic Obstructive Lung Disease (GOLD) 진료지침에의한기준을적용하였다. 설문지구성은다음과같은측정도구로구성되었으며설문조사는약 30분씩소요되었다. 1) 가족보호부담가족보호부담은 CBI (Caregiver Burden Inventory) 12 와 BI (Burden Interview) 13 척도를수정, 번역한 36문항으로측정하였고각문항은 5점척도로구성되었다. 18개문항은주관적보호부담이고, 18개문항은객관적보호부담을측정하기위한문항이다. 주관적보호부담은환자를돌보는과정에서가족들이느끼는감정, 태도, 정서등을말하며, 객관적보호부담은도움을주는다른가족의수, 돌봄에소요되는시간, 돌봄활동등과같은시간적, 신체적제약등을말한다. 점수범위는 0 144점으로, 0 36점은경한부담, 점은중간부담, 점은심한부담, 점은매우심한부담을나타낸다. 2) 가족의건강상태가족의건강상태평가는 Cornell Medical Index 14 를수정, 번역한 69개문항으로측정하였다. 이척도에는감각기계, 호흡기계, 소화기계, 근골격계, 신경계와비뇨기계관련증상에대한문항들이포함되며, 점수범위는

COPD 에서도심리사회경제적자원이취약한저소득층은더욱더많은어려움을경험하며이는높은보호부담으로작용했을것으로보인다. 돌봄특성에서는주보호자이고하루중환자를돌보는시간이긴가족일수록보호부담이큰것으로나타났다. 이런결과는보호부담감이큰 COPD 환자의가족집단이통계적으로유의하게환자를더장시간돌보는것으로보 439

7 JH Kim et al: Burden of caregiver for COPD 고한기존의연구 6 결과와일치한다. 간병을교대할수있는가족의유무는환자를돌보는시간을줄여주고심리적불안감을감소시킬수있다는점에서주관적및객관적보호부담에서모두중요한변수로보고된바있다 9. 그러나본연구에서는환자돌봄을교대할다른가족유무에따른보호부담은통계적인차이가없는것으로나타났는데, 이는간병을교대할가족이있다고하더라도교대가족의역할이미미한경우객관적및주관적으로크게도움이되지않는다고인식하였다고해석해볼수있다. 이에향후연구에서는간병을교대할가족이있는경우그가족구성원의환자돌봄시간이나역할정도를분석할필요가있겠다. 또한가족의건강상태가나쁘고가족관계가좋지않을수록보호부담이증가되었다. 가족의건강상태가보호부담과관계된중요한변수로작용한다는점은가족또한신체적질병이있거나피로, 수면부족등으로건강상태가불편한경우높은보호부담을인지한다고한기존의연구들을 9,18,22 통해서도확인할수있다. 또한가족관계가긍정적일수록가족의보호부담이낮게나타났는데, 긍정적가족관계는가족의응집력이높고의사소통을활발히하며갈등이낮은것을의미한다. 이는좋은가족관계의부재가보호부담으로연결된다는 Bulger 등 23 의보고와일치되며만성정신질환가족연구들 11,24 에서긍정적가족기능이환자와가족의삶의질을높인다는결과들과도연관된다. 환자요인에서는환자의일상생활기능제한정도가가족의객관적및주관적보호부담모두와관련이있는것으로나타났다. 이결과는보호부담척도를개발한 Zarit 등 25 이보호자의부담은환자장애의심각성과매우강하게연관되어있다고한보고와일치한다. COPD 중증도는가족의보호부담과관련이없는것으로나타났는데, Takata 등 6 도 COPD 환자의 FEV 1 수치와가족의보호부담간에통계적으로유의한관련성이없다고밝혀 COPD 환자질환의심각성을나타내는지표인 COPD 중증도나 FEV 1 수치가가족들의환자보호부담과는직결되지않음을알수있다. 그러나본연구및 Takata 등 6 의연구모두 100명미만의소규모표본연구로보다결과를일반화할수있는대규모무작위표본연구를통한후속검증이필요하겠다. 사회적지지요인에서는가족과친구의지지만이전체보호부담및주관적보호부담과유의한음의상관이있었고, 의료진의지지는보호부담모두와유의한상관관계가없었다. 사회적지지는 Lazarus 와 Folkman 26 의스트레스및대처모델에따라환자의간병과같은스트레스상황에 대한대처자원으로지속적으로검증되어왔다. 본연구결과도이러한사회적지지의긍정적역할을일부지지하였으나, 의료진의지지는가족의보호부담과관련성이없다고나타난점이특이할만하다. 의료진의지지는보호부담과음의상관관계가있다는연구 8,9 와관계가없다고한연구 18 가혼재해있다. 또한보호부담이높은가족이의료진의지지에대한요구가높아보호부담이낮은가족보다실제의료진의지지를더많이받았다는보고들도 6,27 있어, 향후의료진의지지와보호부담간에는단순상관관계보다는보호부담이발생한후에도의료진의지지가보호부담을낮추는지에대한조절및완화효과에대한검증이필요하겠다. 본연구는 COPD 환자가족에대한국내의실증적연구가전무한상태에서가족의보호부담수준과그관련요인을탐색한점에서의미가있는연구이지만몇가지제한점을가진다. 먼저, 본연구는 COPD 환자가족대상다른연구들 5,6 보다는표본수가많은편이나소규모표본연구로전체 COPD 환자가족의특성을충분히반영하였다고보기어렵다. 향후에는가능한대규모표본연구결과들이축적되어야겠다. 또한, 향후연구에서는환자요인에서환자의유병기간및다양한질병의중증도측정들을포함한분석을실시하여환자요인과보호부담간의관련성을추가적으로살펴볼필요가있다. 세번째로본연구에서는국내첫연구로 COPD 가족의보호부담관련요인들을중심으로살펴보았는데, 후속연구에서는관련요인들간의상대적영향력을검증하거나선후영향관계를밝혀가족의보호부담감소를위한보다구체적인전략을세워나가야할것이다. 결론적으로 COPD 환자가족은중간정도의보호부담을느끼고있었으며이러한보호부담은가족의교육수준, 직업유무, 소득수준, 주보호자여부, 돌봄시간, 건강상태, 가족관계, 환자의일상생활기능제한정도, 가족및친구의지지와관련이있었다. COPD 환자보호자의보호부담감소를위해서는팀협력을통한환자가족의사회경제적상태, 가족관계, 돌봄특성, 사회적지지에대한사정및평가가필요하다. 스트레스감소및가족관계향상을위한상담과가족및친구등비공식적지지체계의활성화프로그램이주관적보호부담을낮출수있는방안이될수있을것으로생각되며객관적보호부담을낮추기위해서는환자의치료비지원및환자의제한된일상생활기능을원조할수있는지역사회자원과의연결이필요할것이다. 440
