  • Background: Limited studies have been performed to assess readmission following hospitalization for community-acquired pneumonia (CAP) in an Asian population. We evaluated the rates, reasons, and risk factors for 30-day readmission following hospitalization for CAP in the general adult population of Korea. Methods: We performed a retrospective observational study of 1,021 patients with CAP hospitalized at Yeungnam University from March 2012 to February 2014. The primary end point was all-cause hospital readmission within 30 days following discharge after the initial hospitalization. Hospital readmission was classified as pneumonia-related or pneumonia-unrelated readmission. Results: During the study period, 862 patients who survived to hospital discharge were eligible for inclusion and among them 72 (8.4%) were rehospitalized within 30 days. In the multivariable analysis, pneumonia-related readmission was associated with para/hemiplegia, malignancy, pneumonia severity index class ≥4 and clinical instability ≥1 at hospital discharge. Comorbidities such as chronic lung disease and chronic kidney disease, treatment failure, and decompensation of comorbidities were associated with the pneumonia-unrelated 30-day readmission rate. Conclusion: Rehospitalizations within 30 days following discharge were frequent among patients with CAP. The risk factors for pneumonia-related and -unrelated readmission were different. Aspiration prevention, discharge at the optimal time, and close monitoring of comorbidities may reduce the frequency of readmission among patients with CAP.

  • Pneumonia is the cause of significant morbidity and mortality, despite advances in diagnosis and antibacterial treatment. Pneumonia is often misdiagnosed and mistreated up until recently. Recent classification of pneumonia consists of community-acquired pneumonia, health care-associated pneumonia, hospital-acquired pneumonia, and ventilator-associated pneumonia. The etiology, risk factors, and treatment are different among them. This article briefly introduces new concepts and ideas in biomarkers, diagnosis, treatment, prognosis, and prevention of pneumonia during the past 2 years. One of the most frequent subjects of recent papers was those about pandemic H1N1 in 2009.

  • Community acquired pneumonia(CAP) is the most prevalent disease among pneumonia patients and progressed to severe pneumonia. A retrospective study was performed to evaluate antibiotic regimens according to guidelines of Infectious Disease Society of America. From January to October 2005, chart review of 50 patients with CAP was peformed in terms of microbiology and laboratory data of each regimen. Temperature, WBC count, ALT, AST and alkaline phosphatase of each patient were examined for liver toxicity. In three patients received levofloxacin appeared to have normalized temperature and improved cough. The patients who received cefmetazole -aminoglycoside appeared to have worsen LFT(Liver function test). Many patients in flomoxef-aminoglycoside group received mechanical ventilation because of the basis diseases like tuberculosis, diabetes mellitus and hypertension. In conclusion, antibiotic therapy for the treatment of CAP should be selected according to tolerance, bacteria and severity of disease.

  • The emergence of antibiotic-resistant pathogens is a Serious clinical problem in the treatment of infectious diseases that increase mortality, morbidity, hospitalization length, and the cost of healthcare. In particular, $Streptococcus$ $pneumoniae$ is a major etiologic pathogen of pneumonia, sinusitis, otitis media, and meningitis. As the definition of penicillin resistance to $S.$ $pneumoniae$ was recently changed, macrolide-resistant $S.$ $pneumoniae$ is a major resistant pathogen in the community. Infections caused by antibiotic-resistant strains are associated with incorrect use of antibiotics and critical clinical outcomes. For the appropriate use of antibiotics to treat infections, physicians always should have up-to-date information on the current epidemiologic status of antibiotic resistance for common pathogens and their susceptibility to antimicrobials. Appropriate selection of antimicrobials, strict control of infection, vaccination, and development of a feasible national policy of infection control are important strategies for the control of antimicrobial resistance. This review article focuses on the current status of antibiotic-resistant $S.$ $pneumoniae$ in community-acquired pneumonia in Korea.

  • Background: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a severe and life-threatening disease in patients with community-onset (CO) pneumonia. However, the current guidelines lack specificity for a screening test for MRSA infection. Methods: This study was retrospectively conducted in elderly patients aged ${\geq}65years$, who had contracted CO-pneumonia during hospitalization at the Jeju National University Hospital, between January 2012 and December 2014. We analyzed the risk factors of MRSA in these patients and developed a scoring system to predict MRSA infection. Results: A total of 762 patients were enrolled in this study, including 19 (2.4%) with MRSA infection. Healthcare-associated pneumonia (HCAP) showed more frequent MRSA infection compared to community-acquired pneumonia (4.4% vs. 1.5%, respectively; p=0.016). In a multivariate logistic regression analysis, admissions during the influenza season (odds ratio [OR], 2.896; 95% confidence interval [CI], 1.022-8.202; p=0.045), chronic kidney disease (OR, 3.555; 95% CI, 1.157-10.926; p=0.027), and intensive care unit admission (OR, 3.385; 95% CI, 1.035-11.075; p=0.044) were identified as predictive factors for MRSA infection. However, the presence of HCAP was not significantly associated with MRSA infection (OR, 1.991; 95% CI, 0.720-5.505; p=0.185). The scoring system consisted of three variables based on the multivariate analysis, and showed moderately accurate diagnostic prediction (area under curve, 0.790; 95% CI, 0.680-0.899; p<0.001). Conclusion: MRSA infection would be considered in elderly CO-pneumonia patients, with three risk factors identified herein. When managing elderly patients with pneumonia, clinicians might keep in mind that these risk factors are associated with MRSA infection, which may help in selecting appropriate antibiotics.

  • Mycoplasma pneumoniae(M. pneumoniae) is a primary pathogene of the respiratory tract in children. Most studies of such pneumonia involve a group of admitted patients in hospital, usually with major medical illness. We retrospectively studied the epidemiologic and clinical feature of 105 patients with serologically proven M. pneumoigic pneumonia treated at Gwang-Yang Hospital during a epidemic period of Jun. 1993 to Dec. 1993. All cases of pneumonia developed in this period were also reviewed and compared with serologically proven group. The results were as follows. 1. There were 63 males and 42 females, and the male /female ratio was 1.5 : 1. 2. More than half(57%) of cases belonged to 5-9 years of age group, and mean age was 6.5 years old. 3. Mean age was steadily decreased as prevalence of mycoplasmal pneumonia had been subsided. 4. The date of index case was June 26th, and that of median case was 3 months after the index case. 5. A major determinant of the outbreak seemed to be the population density rather than the population size. 6. Recurrence and serious complication were not observed in this period. 7. All cases of pneumonia developed in this period might be attributed to M. pnemoniae. These epidemiologic and clinical characteristics would contribute to the prevention and diagnosis of mycoplasmal pneumonia.

  • Background: Thus far, research studies on community-acquired pneumonia (CAP) have focused on its clinical severity. Recently, it has been determined that procalcitonin (PCT) level is correlated with severity of CAP. A retrospective study conducted at our hospital used risk predictability and PCT to determine whether or no PCT is useful in assessing the severity of CAP. Methods: This study covered 92 CAP cases that were admitted to the respiratory department at Changwon Fatima Hospital between July 1, 2008 and June 30, 2009. All enrolled subjects were measured for infection markers and risk predictability. Results: Based on hospital admission data, enrolled subjects had Pneumonia Severity Index (PSI) scores serving as risk predictors showed that both PCT and white blood cell (WBC) were statistically significant as infection markers (p=0.001, 0.037). Thus, this study used ROC curves in PSI for data analysis. As a result, it was determined that the area under curve (AUC) of PCT and WBC was 0.694 and 0.593 respectively, indicating that PCT has a higher test value for WBC, when PCT was higher than 0.745 ng/mL. In addition, it was found that PCT levels higher than 0.745 ng/mL had higher PSI scores than the group with PCT lower than 0.745 ng/mL (p=0.032). Conclusion: In order to predict risk of pneumonia cases admitted due to symptoms of CAP, it is important to consider PCT as well as PSI, and follow-up monitoring of PCT cases.

  • 본 연구의 목적은 지역사회획득 폐렴 입원 환자의 재원일수의 변이를 분석하기 위해 중증도 모형을 개발하였다. 2004~2006년 퇴원손상환자 조사자료 중 지역사회획득 폐렴환자 5,353건을 연구대상으로 하였으며, 재원일수의 차이분석은 t검정, 분산분석을 실시하였고, 중증도 보정 재원일수 예측 모형은 데이터마이닝 기법을 이용하였다. 여자에 비해 남자, 연령이 많을수록, 의료급여, 응급실 경유 환자의 재원일수가 긴 반면, 병원사망 여부에 따라서는 유의한 차이가 없었다. 개발된 의사결정나무 모형을 이용하여 예측 재원일수를 산출하고 표준화한 값을 비교한 결과 타지역 진료여부에 따라서 재원일수의 차이는 없는 반면, 보험유형과 지역별로 재원일수의 변이가 존재하는 것으로 나타났다. 환자 특성과 중증도를 통제하고 나타난 재원일수의 변이는 공급자 요인으로 설명될 수 있는데, 진료행태나 의료자원에 대한 후속 연구가 필요한 것으로 보인다. 본 연구는 행정 데이터를 이용하여 중증도 모형을 개발하고 변이를 확인하였다는 점에서 활용의 효용성을 높이는 데 기여할 것으로 사료된다.

  • The successful treatment of community-acquired pneumonia requires appropriate, empirical antimicrobial therapy. The etiology and antimicrobial susceptibility of major pneumonia pathogens can differ by country. Therefore, the ideal treatment guidelines for community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia for immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.
