AbstractAbstract PDF
The Acute Physiology and Chronic Health Evaluation (APACHE) II model has been widely used in Korea. However, there have been few studies on the APACHE IV model in Korean intensive care units (ICUs). The aim of this study was to compare the ability of APACHE IV and APACHE II in predicting hospital mortality, and to investigate the ability of APACHE IV as a critical care triage criterion. Methods: The study was designed as a prospective cohort study. Measurements of discrimination and calibration were performed using the area under the receiver operating characteristic curve (AUROC) and the Hosmer-Lemeshow goodness-of-fit test respectively. We also calculated the standardized mortality ratio (SMR). Results: The APACHE IV score, the Charlson Comorbidity index (CCI) score, acute respiratory distress syndrome, and unplanned ICU admissions were independently associated with hospital mortality. The calibration, discrimination, and SMR of APACHE IV were good (H = 7.67, P = 0.465; C = 3.42, P = 0.905; AUROC = 0.759; SMR = 1.00). However, the explanatory power of an APACHE IV score >93 alone on hospital mortality was low at 44.1%. The explanatory power was increased to 53.8% when the hospital mortality was predicted using a model that considers APACHE IV >93 scores, medical admission, and risk factors for CCI >3 coincidentally. However, the discriminative ability of the prediction model was unsatisfactory (C index <0.70). Conclusions: The APACHE IV presented good discrimination, calibration, and SMR for hospital mortality.

AbstractAbstract PDF
There has been little data reporting the usefulness of intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter. The objective of this study is to clarify the usefulness and safety of these methods in comparison with radiologist-performed procedures.
Data of patients with pleural effusion treated with US-guided pigtail catheter drainage were analyzed. All procedures were performed from September 2012 to September. 2013 by a well-trained intensivist or radiologist.
Pleural effusion was drained in 25 patients in 33 sessions. A radiologist performed 21 sessions, and an intensivist performed 12 sessions. Procedures during mechanical ventilation were performed in 15 (71.4%) patients by a radiologist and in 10 (83.3%) by an intensivist (p = 0.678). The success rate was not significantly different in radiologist- and intensivist-performed procedures, 95.2% (20/21) and 83.3% (10/12), respectively (p = 0.538). The average duration for procedures (including in-hospital transfer) was longer in radiologist-performed cases (p = 0.001). Although the results are limited because of the small population size, aggravation of oxygenation, CO2 retention, and decrease of mean arterial blood pressure were not statistically different in the groups. Pigtail-associated complications including hemothorax, pneumothorax, hepatic perforation, empyema, kink in the catheter, and subcutaneous hematoma were not found.
Intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter is useful and safe and may be recommended in some patients in an intensive care unit.
