Randomized Controlled Trial Multicenter Study Clinical Trial
Pediatric mortality probability estimated from pre-ICU severity of illness.
The Pediatric Risk of Mortality (PRISM) score is a measure of illness severity based on abnormalities observed in the bedside examination and laboratory assessment. PRISM scores obtained after pediatric intensive care unit (PICU) admission predict mortality probability, but no previous efforts to evaluate mortality risk before PICU admission have been reported. Our study was performed on patients admitted to PICUs at four pediatric tertiary care centers to derive a quantitative estimate of hospital mortality probability as a function of PRISM scores obtained at referring hospitals before PICU transfer. Performance of the model was tested by evaluating accuracy of mortality predictions obtained from pre-ICU PRISM scores in a separate validation set of patients. ⋯ The pre-ICU PRISM score as a measure of illness severity provides an estimate of hospital mortality probability. Further investigation is required to determine the use of pre-ICU mortality estimates in making clinical decisions.

Randomized Controlled Trial Clinical TrialRandomized, controlled trial of selective digestive decontamination in 600 mechanically ventilated patients in a multidisciplinary intensive care unit.
To evaluate the efficacy of two regimens of selective decontamination of the digestive tract in mechanically ventilated patients. ⋯ In cases of high colonization and infection rates at the time of ICU admission, the preventive benefit of selective decontamination is highly debatable. Emergence of multiple antibiotic-resistant microorganisms creates a clinical problem and a definite change in the ecology of environmental, colonizing, and infecting bacteria. The selection of multiple antibiotic-resistant Gram-positive cocci is particularly hazardous. No beneficial effect on survival is observed. Moreover, selective decontamination adds substantially to the cost of ICU care.

Randomized Controlled Trial Clinical TrialProlonged sedation of critically ill patients with midazolam or propofol: impact on weaning and costs.
To compare the effectiveness of sedation, the time required for weaning, and the costs of prolonged sedation of critically ill mechanically ventilated patients with midazolam and propofol. ⋯ In our population of critically ill patients sedated with midazolam or propofol over prolonged periods, midazolam and propofol were equally effective as sedative agents. However, despite remarkable differences in the cost of sedation with these two agents, the economic profile is more favorable for propofol than for midazolam due to a shorter weaning time associated with propofol administration.

Randomized Controlled Trial Comparative Study Clinical Trial
A controlled trial of nurse practitioners in neonatal intensive care.
To compare a clinical nurse specialist/neonatal practitioner (CNS/NP) team with a pediatric resident team in the delivery of neonatal intensive care. ⋯ CNS/NP and resident teams are similar with respect to all tested measures of performance. These results support the use of CNS/NPs as an alternative to pediatric residents in delivering care to critically ill neonates.

Randomized Controlled Trial Multicenter Study Clinical Trial
[Nosocomial infections intensive care units. A nation-wide prevalence study].
In a large, multicenter survey in 1994, the prevalence of nosocomial infections in German hospitals was examined, predominant pathogens were identified, and possible risk factors evaluated. In this paper the results from the intensive care units (ICUs) are presented. ⋯ Nosocomial infections are seen far more often in ICUs than on normal wards due to the immuno-suppressed state of many ICU patients and the continuous use of invasive diagnostic and therapeutic procedures. Most of these infections are of endogenous origin. Other prevalence surveys have shown results comparable to ours. Daily changing of ventilation tubes is no longer necessary, but is still routine in many hospitals. Infusion sets were also changed more often than required. The use of selective decontamination of the digestive tract for the prevention of pneumonia is still controversial; in our study it was practised in only 1.5% of the cases. The most commonly used drugs for the prevention of stress ulcers were H2-receptor blocking agents, although it has been shown that sucralfate is the better choice, as it can help prevent nosocomial pneumonia. Routine microbiological surveillance of tracheal aspirates and urine was done in 25.9% and 24.6% of the ICUs. No study so far has shown that routine cultures of tracheal secretions and urine have a preventive effect regarding infection.
