Therefore, this study intended to assess the knowledge and compliance of preventive behavior against respiratory tract infection among these workers. Methods: Data were collected from 202 workers in geriatric facilities via a questionnaire-based survey from July 19 to August 8, 2014. Data were analyzed using the SPSS 21.0 program. Results: Among the workers, 44.6% experienced respiratory tract infection in the last 1 year. The score for knowledge of respiratory tract infection prevention among the workers was 10.6 points out of 12. The average score for compliance of the preventive behavior against respiratory tract infection was 34.6 points out of 48. The correlation between preventive knowledge and compliance of the preventive behavior against respiratory tract infection was not verified (r=0.00, P=0.967). Conclusion: In this study, the level of knowledge of respiratory infection prevention among the workers in the elderly care facility was high. However, the level of compliance was not sufficiently high. In addition, no correlation was found between their preventive knowledge and compliance. Therefore, a preventive program that focuses on the compliance of respiratory infection prevention rather than on its knowledge needs to be developed.

62 김옥선 호흡기감염관리는중요한부분이라할수있다. 그러나일부연구에따르면호흡기감염관리수행수준은다른감염관리영역보다비교적낮았다 [8,9]. 노인요양기관에근무하는간호사의감염관리수행수준을조사한한연구에서는 8가지세부영역중호흡기감염관리부분은평균이하였고 [8], 노인요양기관간호사의병원감염관리이행도를조사한한연구에서는 6개의영역중호흡기감염관리가평균이하였다 [9]. 노인요양기관종사자는면역이취약한노인의간호나활동보조등을통해이들과접촉이많으며, 부적절한호흡기감염예방행위는질병을전파시킬수있으므로노인요양기관에근무하는종사자들의호흡기감염예방을위한노력은매우중요하다. 호흡기감염을예방하기위해서는예방법에대한올바른지식과이에따른예방법의이행이중요하다. 호흡기감염을포함한전반적인감염예방에대한지식과그이행정도에대한연구 [10-13] 는다수있으나상급종합병원이나종합병원에근무하는간호사를포함한일부의료종사자를대상으로한연구가대부분이며 [10-12], 노인요양기관종사자들을대상으로한연구로는감염관리에대한연구가주로수행되었고 [6,8,9,13,14], 국내노인요양기관종사자들의호흡기감염예방지식과이행수준에대한구체적인연구는수행된바없다. 이에노인요양기관에서의호흡기감염예방프로그램개발에근거가되는기초자료로서국내노인요양기관종사자들의호흡기감염예방지식과이행도실태조사가필요하다고판단되어본연구를수행하였다. Materials and Methods 1. 연구설계본연구는노인요양기관종사자들의호흡기감염예방지식과이행수준을파악하고, 관계를규명하기위한서술적조사연구이다. 2. 연구대상경기도와전라도에소재한노인요양기관 4곳에근무하는종사자들과노인간호사회보수교육에참여한노인요양기관종사자를대상으로하 였다. 연구대상자수는 G*power program version 3.1.3 (Franz Faul, University Kiel, Germany) 을사용하여상관관계분석에필요한최소표본수를구하였다. 중간수준의효과크기인 0.3, 유의수준 0.05, 검정력 0.95로양측검정할때최소 134명의표본이필요하였다. 이에기초하여무응답자를고려하여 250명에게설문지를배부하였고, 연구참여에동의하고모든항목에응답한 202명의자료를분석에이용하였다. 3. 연구도구본연구의도구는구조화된자가보고식설문지를이용하였다. 설문지는대상자의일반적특성과호흡기감염예방관련특성, 호흡기감염예방지식, 호흡기감염예방이행에대한내용으로구성하였다. 1) 일반적특성및호흡기감염예방관련특성문헌고찰을기초로일반적특성과호흡기감염예방관련특성에대한 12문항을연구자가개발하였다. 일반적특성은대상자의인구학적특성과노인요양기관의특성에대한문항으로성별, 연령, 학력, 직종, 노인요양기관근무경력, 근무하는기관의병상수와소재지를포함한 8문항으로구성하였다. 호흡기감염예방관련특성은호흡기감염예방교육경험, 기침예절에대해알고있는지, 최근 1년이내에호흡기감염경험, 전년도인플루엔자유행기간동안인플루엔자예방접종을했는지를포함한 4문항으로구성하였다. 2) 호흡기감염예방지식호흡기감염예방지식은 Yoon & Kim이개발한임신부의호흡기감염예방지식측정도구를연구자에게수정사용동의를받은후노인요양기관종사자에게적절하게수정하여사용하였다 [15]. Yoon & Kim의도구 15문항중 3문항을삭제하고 12문항으로수정하였다. 수정한도구는감염관리전문간호사자격증을소지하고 10년이상의감염관리경험이있는간호학과교수 4인과감염관리전문간호사 1인에게내용타당도검증을받아표현이모호한문장을수정하였으며, 12 문항모두내용타당도지수 (content validity index) 가 80% 이상이었다. 호흡기감염예방지식측정

Armonk, NY, USA) 를이용하여분석하였다. 대상자의일반적특성, 호흡기감염예방지식과이행정도는빈도, 백분율, 평균과표준편차를산출하였다. 대상자의특성에따른호흡기감염예방지식과이행정도는 t-test, oneway ANOVA 로분석하였으며, one-way ANOVA 로분석후유의한변수는 Scheffe test로사후검증을하였다. 지식과이행도간의상관관계분석은 Pearson's correlation coefficient를이용하였다. Results 1. 대상자들의특성대상자들의연령은평균 43.56세였고, 86.0% 가전문대학이상의학력이었다. 직종별로는간호사가 64.2% 로가장많았고, 기타직종으로간호조무사, 요양보호사, 간병인, 사회복지사등이있었으며, 노인요양기관근무경력은평균 5.85년이었다. 대상자들이근무하는노인요양기관의소재지는경기도가 61.2% 로가장많았고, 침상수는평균 264.37개였다. 53.0% 가호흡기감염예방교육을받은경험이있었으며, 78.2% 는전년도인플루엔자유행기간동안인플루엔자예방접종을했고, 44.6% 는최근 1년이내호흡기감염경험이있었다 (Table 1).

Discussion 호흡기감염은크고작은유행이가끔씩발생하기때문에조사시기에따라감염발생빈도에상당한차이를보일수있다 [16,17]. 본연구에서노인요양기관종사자의최근 1년간호흡기감염률이 44.6% 인결과에기초해볼때상당수의종사자들이호흡기감염을경험하고있음을알수있으며, 이들이면역이저하된노인에게감염을전파시킬수있음을감안할때감염전파예방을위한노력이더욱필요하다. 호흡기감염의전파를예방하기위해서는올바른감염예방법에대해알고있어야한다. 본연구에참여한노인요양기관종사자들의호흡기감염예방지식점수는과거연구에서의지식점수보다높았다 [15,18-20]. 본연구대상자들의지식점수가높은것은 2009년신종인플루엔자유행이후다양한대중매체를이용하여호흡기감염예방에대한정보를국가가제공하였기때문에조사대상자들이호흡기감염예방에대해일정수준알고있었으리라판단된다. 신종인플루엔자유행이후에시행된임신부들의호흡기감염예방지식 [15] 보다도본연구대상자들의지식점수가높은것은조사대상이일반인이아니라간호사를포함한노인요양기관종사자들이었으므로면허증이나자격증취득을위한교육과정이나보수교육등을통해일정수준지식을갖추었기때문으로판단된다. 이전연구에서감염예방이행도는 62.1-91.3% 수준으로연구마다차이가있으며 [10-13,15], 본연구에서의호흡기감염예방이행도는선행연구에서보고된감염예방이행수준범위안에속하였다. 그러나본연구대상자들이감염에취약

호흡기감염예방지식과이행도 67 한노인이고이들과접촉이많은업무특성을감안할때감염예방이행수준을좀더높이기위한노력이필요하다. 특히세부항목중손위생과예방접종은이행수준이높은데비해격리주의와건강관리부분은낮았으므로격리주의와건강관리부분의이행수준을높이기위한노력이필요하다. 본연구에서전년도인플루엔자예방접종여부에따른호흡기감염예방지식수준에는차이가없었으나감염예방행위이행수준은차이가있었다. 이는호흡기감염예방행위인인플루엔자예방접종에영향을미치는요인으로지식은유의하지않았으나전년도예방접종이유의한요인이었던연구결과와도유사하다 [21,22]. 그러므로호흡기감염예방이행증진프로그램을개발할때는행위의습관화를유도할수있는전략이효과적일것으로보인다. 교육은지식과이행을증진시키기위해가장흔히사용되는전략으로교육을통해지식을함양하며, 긍정적인행동의변화를유도할수있다 [23]. 그러나본연구에서는호흡기감염예방교육을받은경우가그렇지않은경우보다감염예방이행수준은높았으나지식수준은차이가없었다. 교육여부에따른지식수준에차이가없었던것은 2009년신종인플루엔자가유행할때정부차원에서라디오등다양한대중매체를이용하여호흡기감염예방법에대한교육을시행하였으며 [24], 신종인플루엔자유행이지나간이후에도호흡기감염예방에대한정보를제공하고있다. 비록본연구대상자들이교육에참여하지는않았으나 90.6% 가기침예절에대해알고있는것으로추측해보면, 대상자들이호흡기감염예방교육을받지않았다고했으나기침예절에대해알고있는것은대중매체를통한호흡기감염예방홍보의주요내용중에하나로기침예절에대한교육과홍보가이루어졌으므로이를통해정보를습득하는것으로판단된다. 호흡기감염예방지식과이행간에상관관계를분석한결과지식과이행간에는상관관계가없었다. 이는연구에참여한대상자들의지식수준이상당히높았으며, 높은지식수준은변별력있는변수로서의역할을하지못함으로인해지식과이행간에상 관관계가없었을것으로판단된다. 그러므로노인요양기관종사자들의건강증진과이들로인한감염의전파를예방하기위해호흡기감염예방프로그램을계획할때는호흡기감염예방이행수준을증진시키기위해지식수준을높이려는방법은효과가낮을것으로생각되며, 본연구에서이행수준이모두낮았던직종을중심으로이행수준을높이는데목적을둔프로그램이필요하다. Summary 배경 : 노인요양기관종사자들은면역이저하된노인들에게호흡기감염을전파할수있으므로이들의호흡기감염예방은중요하다. 이에노인요양기관에서의호흡기감염예방프로그램개발에근거가되는기초자료로서노인요양기관종사자들의호흡기감염예방에대한지식과이행도를파악하기위하여시행되었다. 방법 : 2014년 7월 19일부터 8월 8일까지설문지를이용하여노인요양기관에근무하는 202명의종사자들에게서자료를수집하였다. 수집한자료는 SPSS 21.0 Program을이용하여분석하였다. 결과 : 노인요양기관에근무하는조사대상자의 44.6% 가최근 1년이내에호흡기감염을경험하였다. 조사대상자들의호흡기감염예방지식은 12점만점중 10.6점이었으며, 감염예방이행점수는 48점만점중 34.6점이었다. 호흡기감염예방지식과이행간에는상관관계가확인되지않았다 (r=0.00, P=0.967). 결론 : 본연구에서노인요양기관에근무하는종사자들의호흡기감염예방지식수준은높았으나이행은높은수준이아니었고, 지식과이행간에상관관계가없었다. 그러므로지식수준을높이기보다다양한호흡기감염예방이행수준을높이는데초점을둔프로그램개발을고려해야할것이다.
