우리나라는 세계적으로 유례를 찾아볼 수 없을 정도 로 빠른 속도로 노령화가 진행되고 있다. 65세 이상 노인인구는 2006년에 이미 9.5%로 고령화 사회에 이 르렀으며 2018년 14.3%, 2026년 20.8%로 초고령 사회에 도달할 것으로 전망된다(통계청, 2006). 노인인 구는 각종 만성질환에 이환되는 비율이 높으며 특히 호 흡기계 방어능력 저하로 폐렴 발생률이 증가한다. 지역 획득폐렴(community acquired pneumonia; CAP) 환자의 평균연령은 63.1~65.8세로(오흥국 등, 1997; Marrie & Wu, 2005) 중증폐렴 입원환자의 65%가 60세 이상 노인인 것으로 보고되었다.
This study was done to identify differences between aspiration pneumonia and community acquired pneumonia (CAP) according to demographic characteristics and medical outcomes for elderly patients. Method: From January 2004 to December 2007, data were collected from 105 patients (> 65 years old) with aspiration pneumonia and 311 with CAP. General characteristics, pneumonia severity of illness score (PSI score) and medical outcomes were obtained by reviewing the medical records of those patients. Data were analysed using SPSS window 12.0 version statistics package. Results: The aspiration pneumonia group was older (p<0.05), and more dependent in walking. The incidence of stroke, dementia, Parkinson's disease (p<0.001) and diabetes mellitus (p= 0.027) was higher in the aspiration pneumonia group than in the CAP group. PSI score (121.47 vs 90.65 points), length of hospital stay (17.77 vs 9.94 days) and mortality (17.1 vs 5.1%) were significantly higher in aspiration pneumonia group than in the CAP group. In logistic regression, the factors predicting aspiration pneumonia were Dementia (OR=44.37), Parkinson's disease (OR=18.63), stroke (OR=17.17), confusion (OR=8.62), hypoalbuminemia (OR=2.89). Conclusion: Aspiration pneumonia was more common in dependent malnourished elderly patients with neuro-degenerative diseases. Special attention has to be paid to these patients to decrease the incidence of aspiration pneumonia in the older population.
