Randomized Controlled Trial Clinical Trial
Association of mortality with age of blood transfused in septic ICU patients.
To determine, retrospectively, the age of packed red blood cell (PRBC) units transfused to patients admitted to the ICU with the diagnosis of severe sepsis and to correlate this variable with outcome. ⋯ This is the first study to report a correlation of mortality with the age of PRBC transfused. The cause of this association is unclear. If this association is confirmed by a prospective randomised trial it would have major implications for the use of PRBC in severe sepsis.

Treatment of cancer has contributed to a growing number of immunocompromised patients with life-threatening nosocomial infections (NI). High mortality with considerable cost is observed when they are admitted to the intensive care unit (ICU). Few studies on infection control and surveillance have been undertaken in this population group. ⋯ The high rates reported in this study may reflect a combination of several factors related to the underlying illness, neutrophil count, and exposure to invasive procedures. The adjusted infection rates described here provide specific surveillance data for further interhospital comparisons and also to assess the influence of invasive medical interventions, allowing the implementation of preventable measures to control infections.

Comparative StudyImpact of different customization strategies in the performance of a general severity score.
To compare the impact of two different customization strategies in the performance of the admission Mortality Probability Model II (MPM II0) using formal statistical assessment. ⋯ In this ICU patient database, second-level customization was more effective than first-level customization in improving the overall goodness-of-fit of MPM II0 and should probably be chosen as the preferential strategy to improve the fit of a model when the sample size is large enough. However, second level customization had only a slight impact on discrimination. Its effects on the uniformity of fit are insufficient to overcome the problems that can arise when the model is applied in populations in which the case-mix is distinct from the population where it was originally developed.

This descriptive correlation study evaluated the pain intensity, pain distress and morphine consumption in patients recovering from coronary artery bypass grafting (CABG) surgery in an Australian intensive care unit (ICU) and compared patients' pain intensity ratings with ratings of the nursing staff. Forty-three patients and their attending nurses rated patients' pain intensity and pain distress levels at 8-hourly intervals throughout their stay in ICU. A maximum of five assessments was obtained in the first 48 post-operative hours from patients and their nurses. ⋯ Significant differences occurred between patients' and nurses' average pain intensity scores at each time point and, except for worst pain intensity measures at the first assessment, nurses consistently underestimated patients' pain. These results indicate that patients in ICU following CABG can experience considerable pain, which is not always relieved. The application of regular systematic pain assessment and improved communication, together with the administration of adequate pain relief are necessary if nurses are to manage patients' pain effectively.
