Methods: Through a literature search of the databases including RISS, Medline, and the Cumulative Index to Nursing and Allied Health Literature, a total of 41 studies published between January 2000 and June 2016 were identified. A comprehensive review was performed guided by a framework developed by the researchers. Results: Nine nonverbal pain measurement scales that were mentioned more than twice in the selected studies were identified. Facial expression, verbalization and vocalization, and body movements were categories presented in all of the scales. The Pain Assessment In Advanced Dementia Scale (PAINAD) was most frequently reported in studies and the Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) showed the highest internal consistency (Cronbach's =.73~.92) while the Doloplus-2 showed the highest inter-rater reliability (r=.77~.97) and the PAINAD and the highest concurrent validity (r=.65~.95). Conclusion: The PAINAD, PACSLAC, and Doloplus-2 are useful scales for use with elders. However, it is difficult to conclude which scale is the most appropriate because of insufficient evidence. More methodological studies are necessary to examine reliability, validity and clinical utility of the measures identified above. Key Words: Aged, Pain measurement, Review 서론 1. 연구의필요성 전세계적으로 65세이상노인인구가증가하고있어인구중 65세이상비율은 2015년 8.2% 에서 2060년 17.6% 로증가할전망이다. 더구나우리나라의고령화는급속도로진행되고있어, 2015년고령인구의비중은 13.1% 로 1960년에비해 4.5 배증가한수준이며, 2030년에는 24.3% 로 2060년에는 40.1% 로증가할것으로보고되고있다 [1]. 이렇게급속도로고령화사회에접어들고평균수명의증가에따라노년기의건강관리및삶의질에대한관심또한증가하고있다 [2]. 통증이란실제로일어나거나혹은아직은잠재적인조직손상과관련되어나타나는불쾌한감각적및정서적경험을말한다 [3]. 이러한통증은주관적이고개인적인것으로, 기억 감정 문화등에도연관되는복합적현상이다. 통증은급성통증과만성통증으로분류되며, 만성통증은 3개월이상지속되는통증을의미한다 [4]. 전체노인인구의약 89.2% 는한가지 주요어 : 노인, 통증사정도구, 문헌고찰 Corresponding author: Song, Jun-Ah College of Nursing, Korea University, 145 Anam-ro, Seongbuk-gu, Seoul 02841, Korea.

2 이경미 송준아 이상의만성질환을앓고있는것으로조사되었는데 [5], 노인들이가지고있는만성질환과노화로인한신체변화로노인의 89% 정도가통증을경험하는것으로보고되고있다. 지역사회거주노인들의 35~45% 가일상적인통증을겪고있으며, 노인요양시설거주노인의 45~85% 가만성통증을겪는것으로나타났다 [6]. 노인의만성통증은우울, 불안, 낙상, 영양불균형, 인지능력저하, 수면부족, 일상생활과사회적활동능력저하, 의료비증가, 삶의질감소등을유발한다 [6]. 이렇게노인의만성통증은신체적인문제뿐아니라심리적, 사회적인기능장애를초래하므로지속적이고체계적인만성통증관리의필요성이부각되고있다 [7]. 정확한통증사정은통증을체계적으로관리하고치료하기위해필수적이다. 하지만대부분의노인이만성통증을겪고있음에도노인의통증사정은어려운부분이다 [8]. 노인의정확한통증사정을가로막는문제는노인환자측면, 의료진측면, 구조적측면에서존재한다 [9]. 노인환자의측면에서가장큰문제는인지장애이며, 이외에도성인을위한통증사정도구사용의어려움이보고되었다. 의료진의문제는노인의통증을정상적인노화과정또는망상이나치매로만간주하는것이며, 또한, 구조적인문제로노인의적절한통증사정및조절에대한논의가제대로이루어지지않는것으로제시되었다. 이러한다양한문제로인한부정확한통증사정은결과적으로노인이겪고있는만성통증에대한적절한처치가이루어지지않게한다 [6]. 따라서간호사는노인의통증을정확하게사정하고이를적절하게관리하여노인의삶의질을높이도록도와주어야한다 [10]. 통증은주관적이고개인적인것으로, 기억 감정 문화등에도연관되는복합적현상이다 [11]. 따라서대상자의통증에 대한자가보고가통증사정에가장정확하고중요한자료이다 [8,11]. 일반적인성인대상자에게사용하는자가보고식통증사정도구로는숫자척도도구 (Numeric Rating Scale, NRS), 언어적서술형척도 (Verbal Descriptive Scale, VDS), 얼굴표정척도 (Face Pain Scale, FPS) 등이있다. 하지만이러한자가보고식통증사정도구들은노인에게적용하는데에많은어려움이있는데, 이는인지능력의저하, 의사소통의어려움등을가진노인에게정확한통증을언어로전달하는것은어렵기때문이다 [12]. 그런이유로인지능력의저하로인해통증사정도구에대한이해도가낮아지고의사소통이불가능한노인에게자가보고식통증사정도구는신뢰도가떨어져사용이추천되지않고있다 [13]. 이러한문제를해결하기위해 1990년대중반이후부터세계적으로다양한비언어적통증사정도구가개발되어왔다. 비언어적통증사정도구는행동변화의관찰을기본으로하고있다. 이러한행동과기능의변화를관찰하는것은수면, 식욕, 신체활동, 얼굴표정및몸짓언어등을포함한다 [14]. 미국노인병학회에서는비언어적통증사정시얼굴표정, 구두 / 발성, 신체움직임, 상호작용변화, 일상생활패턴변화, 정신상태변화의 6가지행동지표영역 (Table 1) 을포함할것을권유하고있다 [15]. 이중구두 / 발성은통증이있음을언어로적절하게표현하기보다는통증과관련된행동의일부로한숨쉬기, 신음소리내기, 거친숨소리, 단순하고반복적인중얼거림, 누군가를지속적으로부르기, 욕하기등의의미없는음성 ( 예 : 등 ) 을내는경우를의미하는것으로언어적표현이제한된노인환자에서주의깊게관찰해야할통증관련행동으로제시되어있다. 심각한인지장애를겪고있는노인환자에게는비언어적통증사정도구를통한통증사정이효과적인것으로나 Table 1.

9 노인을위한비언어적통증사정도구에관한문헌고찰 Seniors with Limited Ability to Communicate (PACSLAC) 가 10편 (24.3%) 언급되었다. 그외에도 Doloplus-2 (6편, 14.6 %), Abbey (4편, 9.7%), The Checklist of Nonverbal Pain Indicators (CNPI)(4편, 9.7%), The Non-Communicative Patient's Pain Assessment Instrument (NOPPAIN)(3편, 7.3%), Mobilization-Observation-Behavior-Intensity-Dementia Pain Scale (MOBID-2)(3편. 7.3%), Pain Assessment in Dementing Elderly (PADE)(2편, 4.8%), Certified Nurse Assistant Pain Assessment Tool (CPAT)(2편, 4.8%) 의도구들이연구되었다. 분석된비언어적통증사정도구들의항목수는 5개부터 60 개까지다양하였으며, 이중 PACSLAC가 60개로가장많은항목수를가진도구로나타났다. 미국노인병학회에서권고하는 6가지행동지표영역을포함하는지여부와관련하여서는비언어적통증사정도구들이최소 3가지영역은모두포함하였으며, 가장많은영역을포함하는도구는 PACSLAC와 Abbey로상기 6가지영역을모두포함하는것으로나타났다. 분석된도구들은모두얼굴표정, 구두 / 발성, 신체움직임의세영역을포함하고있었다. 분석대상문헌들은대부분도구들의신뢰도와타당도를검증하여제시하고있다. 41편의연구에서 11편을제외한연구에서신뢰도와타당도를제시하였다. 신뢰도는내적일관성, 평가자간신뢰도, 평가자내신뢰도가검증되었으며, 타당도는동시타당도와변별타당도로검증되었다. 각연구에서검증된모든신뢰도와타당도는최솟값과최댓값의범위로제시하였다. 총 9개의도구들의내적일관성신뢰도는.06부터.97, 평가자간신뢰도는.25~.97로다양하게나타났다. 동시타당도는.22부터.95로나타났다. 각도구의내적일관성신뢰도는 PACSLAC (.73~.92), PAINAD (.55~.90) 순으로높게나타났으며, 평가자간신뢰도는 Doloplus-2 (.77~.97), PACSLAC (.63~.96) 순으로높게나타났다. 동시타당도의경우 PAINAD (.65~.95) 와 CNPI (.33~.95) 가높은것으로나타났다. 문헌들에서는각도구들의유용성및제한점을제시하고있었다. 도구를이용하여통증을측정하는데걸리는시간은 5 분에서 10분으로나타났으며, Abbey와 CPAT가 1분으로가장적은시간이걸렸다. 반면에 PADE는 10분으로가장많은시간이걸리는것으로나타났다. 특히, MOBID-2와 PADE는점수를측정하는과정이복잡하고어려워훈련이필요한것으로보고되었다. 측정된점수에대한해석은 Abbey, CNPI, CPAT만이가진것으로나타났으며, Doloplus-2의경우는통 증여부를판별하는 Cut-off score만을가지고있었다. 도구들은대부분간호사를위해개발된것이었으며, NOPPAIN과 CPAT의경우간호조무사를위해개발된도구였다. 총 9개의비언어적통증사정도구중문헌에서의언급횟수, 신뢰도및타당도, 유용성및제한점을조합해보면, PAINAD, PACSLAC, Doloplus-2의세도구가전세계적으로연구가많이진행되며유용한것으로확인되었다. 논의 본연구는 2000년부터최근까지노인을대상으로한비언어적통증사정도구에대한선행연구를고찰하고, 연구들에서언급되어진비언어적통증사정도구의특성에대해분석하였다. 본분석을통하여최근까지의노인을위한비언어적통증사정도구에대한전세계적연구동향을파악할수있었으며, 향후노인대상자의비언어적통증사정을위해진행되어야할연구를위한기초자료를제공하고자하였다. 본연구의분석대상문헌 41편중 2006년부터 2010년사이에발표된연구가 23편 (56%) 으로절반을차지하였다. 이것은 2000년대초반에는도구의개발이시작되는시기라많은연구가진행되지않았으나, 여러도구들이개발된 2006년부터후속연구가진행된것을알수있었다. 이것은 2000년대에노인을위한비언어적통증사정도구들이개발되었음에도실무에서의사용은많이이루어지지않아다양한후속연구가진행되고있는것으로보인다 [6]. 전세계적으로노인인구의증가와더불어통증관리에대한관심이늘어나고있어, 이러한비언어적통증사정도구에대한요구는지속적으로증가할것으로보인다 [19]. 하지만전세계적으로꾸준히연구가이루어지는것에비해국내에서이루어진연구는단 1편에불과해국내에서의추가적연구가필요하다는것을보여준다. 총 9개의비언어적통증사정도구들을비교 분석한결과문헌에가장많이언급된도구는 PAINAD, PACSLAC, Doloplus-2의순이었으며, 내적일관성신뢰도는 PACSLAC, PAINAD 순으로높게나타났으며, 평가자간신뢰도는 Doloplus-2, PACSLAC 순으로높았다. 이것으로현재까지많은연구가진행되고사용이유용한도구는 PAINAD, PACSLAC, Doloplus-2로볼수있었으며, 이것은다수의선행연구 [14,18, 20-23] 의결과와일부일치하였다. PAINAD는여러연구에서임상적으로유용하며, 신뢰도와타당도가높게나타났다 [18,21]. PAINAD는 5가지항목 ( 호흡, 부정적음성화, 얼굴표정, 몸짓언어, 달램 ) 을각각 0,1,2 Vol. 18 No. 3,

10 이경미 송준아 점을매겨통증점수를내는도구이다. PAINAD는사용이간단하여 2시간정도의훈련만이필요하며, 점수측정에 5분내외로걸리는것으로나타났다 [18]. 본연구에서분석한결과가장많은문헌에언급되었으며, 높은신뢰도와타당도를보여줬다. 하지만점수측정시통증이없는것을의미하는 0 점으로나타나는경우가많았으며, 점수에대한자세한해석이없어추가적인연구가필요하다 [14,18]. 또한통증이있다고판단하고중재를할수있는 cut-off score가없는것이아쉬우며 [18] 추가적인연구가진행되어야할필요가있겠다. PACSLAC는여전히개발단계에있음에도다양한연구에서실무유용성이높은것으로밝혀졌다. 특히 PACSLAC는미세한행동변화를발견하는부분에서가장정확한것으로나타났다 [24]. PACSLAC는네가지영역총 60개의문항으로이루어져있다. 얼굴표정 (13문항), 활동 / 신체움직임 (20문항), 사회성 / 인격 / 기분 (12문항), 생리적변화 / 식욕과수면변화 / 음성표현 (15문항) 으로구성되어있다. 항목이많지만측정이간단하여 5분정도로소요되며, 실제임상에서사용한연구에서도높은신뢰도를보였다 [13,25]. 또한기존형태의축소판인 PACSLAC-II도개발되었으며원본과동질성이입증되고통증과관련이없는항목들이삭제되어사용이더용이해졌다 [26]. 하지만 PACSLAC의점수가증가하는것이통증의증가를의미하지만, 점수에대한보다정확한해석이없어이부분에대한추가적인연구가필요하다 [14]. 또한 PAINAD와마찬가지로 cut-off score가없는것이제한점이며 [18] 추가적인연구가필요한것으로사료된다. Doloplus-2 역시신뢰도와타당도및임상적유용성이모두높은것으로보고되었다 [14,23]. Doloplus-2는통증을유발할수있는 10가지상황을관찰하고통증점수를내는것으로신체적반응, 정신운동성반응, 정신사회적반응의세가지영역으로분류된다. 각항목들을 0점에서 3점까지점수를매기는것이며, cut-off score는 5점으로그이상부터통증이있다고판단하였다. 하지만이 cut-off score와관련된정확한근거가부족하며, 점수에대한자세한해석이없어이부분에대한추가적인연구가필요한것으로제시되었다 [14]. 또한도구의세가지영역중정신사회적반응은판단하기어려운부분으로재평가가필요하다 [23]. 하지만많은연구가진행되고도구가개발되고있음에도불구하고여전히특정한도구가가장유용하다고할수있는확실한증거가부족하며 [27], 그어떤도구도가장좋은기준이된다고주장하기어렵다 [23]. 본연구에서 PAINAD, PACSLAC, Doloplus-2를유용한도구라고결론을내렸지만, 이것이모든 국가와모든대상자에게적절한것은아니다. 통증은개인적이며문화적인요소에도영향을받는부분이기때문에각나라에알맞은통증사정도구도다를수있다. 통증사정도구의선택은임상적환경, 통증사정과정, 사용자등을모두고려해서결정해야한다 [24]. PAINAD는간단하게측정이가능하고통증과관련된행동에초점을맞추기때문에즉각적인중재가필요한임상적환경에서적용이용이하다 [21]. PASCLAC는포괄적인행동을관찰하는도구로써지속적으로통증을관찰하는환경에서적합하며, 통증에대해기준으로삼거나월별또는분기별로측정시에사용하는것이좋다 [21]. Doloplus-2는대상자의특성에대해잘알고있어야사용이가능하므로노인요양시설또는요양병원과같은환경에서적용이용이하다 [28]. 하지만이에대한근거를제시하는후속연구들이더필요할것으로사료된다. 결론 본연구는 2000년부터 2016년까지노인을대상으로한비언어적통증사정도구에대한선행연구들을분석하여연구동향을파악하고향후노인을위한비언어적통증사정도구에대한연구및임상활용에대한기초자료를제공하고자실시되었다. 본연구를통해, 2006년이후노인을위한비언어적통증사정도구와관련된연구가많이진행된것을알수있었으며요구도의증가에따라지속적인연구가필요한것으로확인되었다. 또한노인의통증관리에대한관심이증가함에도불구하고국내에서이루어진연구는단 1편에불과하여, 국내에서노인의비언어적통증사정도구에관련된연구는미흡한실정이었다. 국외의다양한연구결과를토대로국내에서도우리나라노인의특성및임상현장의특성을반영하여적용이용이할수있도록많은후속연구가진행되어야할필요가있겠다. 특히, 본연구에서비언어적통증사정도구를분석한결과 PAINAD, PACSLAC, Doloplus-2가현시점에서유용한도구로판단되어지지만, 여전히확실한증거가부족하며어떤도구가가장적절한지에대한결론을내리기어렵다. 따라서향후우리나라노인을대상으로이세가지도구에대한번안, 신뢰도및타당도평가, 및임상유용성등에대한연구가우선시되어야할것으로사료된다. 본연구는국내 외노인을위한비언어적통증사정도구를종합적으로고찰함에있어다음의제한점이있으며, 이는본논문의결과를해석할때고려되어야할것이다. 첫째, 검색어 156 Journal of Korean Gerontological Nursing
