A prospective multicenter observational study was performed to investigate the epidemiology and outcomes of community-acquired severe sepsis and septic shock. Subjects included 1,192 adult patients admitted to the 22 participating intensive care units (ICUs) of 12 university hospitals in the Korean Sepsis Registry System from April, 2005 through February, 2009. Male accounted for 656 (55%) patients. Mean age was 65.0 +/- 14.2 yr. Septic shock developed in 740 (62.1%) patients. Bacteremia was present in 422 (35.4%) patients. The 28-day and in-hospital mortality rates were 23.0% and 28.0%, respectively. Men were more likely to have comorbid illnesses and acute organ dysfunctions, and had higher mortality and clinical severity compared to women. While respiratory sources of sepsis were common in men, urinary sources were predominant in women. In the multivariate logistic regression analysis, cancer (odds ratio 1.89; 95% confidence interval 1.13-3.17), urinary tract infection (0.25; 0.13-0.46), APACHE II score (1.05; 1.02-1.09), SOFA score on day 1 (1.13; 1.06-1.21) and metabolic dysfunction (2.24, 1.45-3.45) were independent clinical factors for gender-related in-hospital mortality. This study provided epidemiological and clinical characteristics of community-acquired severe sepsis and septic shock in ICUs in Korea, and demonstrated the impact of clinical factors on gender difference in mortality.

Knowledge of clinical demographics and outcomes of mechanically ventilated patients is important but there are few prospectively collected data in Korea. The objective of the present study was to describe the current status of mechanically ventilated patients in Korea as of 2010. We analyzed the data of Korean patients (275 patients in 12 Korean intensive care units [ICU]) participating in a multinational prospective cohort study on mechanical ventilation. The most common indication for mechanical ventilation was pneumonia (23%). Pressure-limited ventilation modes were preferred over volume-cycled ventilation modes. Non-invasive positive pressure ventilation was used in only seven (2%) patients as the initial ventilatory support. Median duration of mechanical ventilation was 7 days and ICU mortality was 36%. The multiple logistic regression model revealed that the Simplified Acute Physiology Score II (SAPS II) score at ICU admission (odds ratio [OR], 1.034; 95% confidence interval [CI], 1.001-1.036; P=0.033), peak pressure (OR, 1.054; 95% CI, 1.016-1.095; P=0.006), and the number of failed organs (OR, 2.132; 95% CI, 1.634-2.781; P<0.001) were independently associated with ICU mortality. This study provides a snapshot of current practice of mechanical ventilation in Korea.

PURPOSE: With a dramatic improvement in the survival rate of the very low-birth-weight (VLBW) infants, systemic fungal infections, especially candida sepsis, appear to represent an increasing problem among high risk neonatal patients. So, we evaluated epidemiological and clinical features of candidal sepsis in VLBW infants. METHODS: Among the VLBW infants who were admitted to NICU of the Dongsan Medical Center, Keimyung University between January 1996 and December 1999. Patients with candidal sepsis, which was proven by cultures, were evaluated for prediposing factors, clinical manifestations, and treatment and sequelae. RESULTS: 1) A total of 22 infants, representing 9.6% of the total admissions of infants with birth weight < 1,500 gram were diagnosed with candidal sepsis during hospitelizations. The mean gestational age was 29.5 weeks (27-36.3 weeks) and the mean birth weight was 1,260 gram (860-1,480 g). 2) The predisposing factors were long-term use of antibiotics, prolonged parenteral hyperalimentation with lipid, indwelling catheter, steroid treatment and mechanical ventilation. 3) The mean age of onset infection was 48 days. The most common presenting clinical manifestations were temperature instability (46.2%), apnea and/or bradycardia (42.3%), feeding intolerance (42.3%), and decreased activity (38.5%). The most common hematologic change was thrombocytopenia (53.9%). 4) The most frequent organism was Candida albicans (65.4%), following by species were C. tropicalis (11.5%), C. lusitaniae (7.7%) and C. parasilosis (7.7%). 5) After treatment of intravenous amphotericin B with or without diflucan, the mortality rate was 13.6% and significant complications were not noted. CONCLUSION: We reviewed the clinical spectrum of candidal sepsis in the VLBW infants in NICU, and concluded that early diagnosis and treatment may be important in improving the mortality and morbidity of VLBWI with candidal sepsis.
