Randomized Controlled Trial Clinical Trial Retracted Publication
Does the type of volume therapy influence endothelial-related coagulation in the critically ill?
The endothelium plays an important role in the regulation of haemostasis by producing substances such as thrombomodulin (TM). The influence of long-term volume replacement with different types of fluid on the TM-protein C-protein S system was investigated in a prospective, randomized study. Thirty trauma patients and 30 patients suffering from sepsis after major surgery received either 10% low-molecular weight (LMW) hydroxyethylstarch solution (HES-trauma, n = 15; HES-sepsis, n = 15) or 20% human albumin (HA-trauma, n = 15; HA-sepsis, n = 15) for 5 days to maintain central venous pressure (CVP) between 12 and 16 mm Hg. ⋯ TAT (indicating intravascular coagulation) did not differ between the two fluid groups. We conclude that in trauma patients, the type of volume therapy had no influence on the TM-protein C-protein S system. In sepsis patients, volume therapy with HES was beneficial, whereas infusion of HA had no substantial positive effect on endothelial-associated coagulation.

Randomized Controlled Trial Multicenter Study Clinical Trial Controlled Clinical Trial
A controlled trial to improve care for seriously ill hospitalized patients. The study to understand prognoses and preferences for outcomes and risks of treatments (SUPPORT). The SUPPORT Principal Investigators.
To improve end-of-life decision making and reduce the frequency of a mechanically supported, painful, and prolonged process of dying. ⋯ The phase I observation of SUPPORT confirmed substantial shortcomings in care for seriously ill hospitalized adults. The phase II intervention failed to improve care or patient outcomes. Enhancing opportunities for more patient-physician communication, although advocated as the major method for improving patient outcomes, may be inadequate to change established practices. To improve the experience of seriously ill and dying patients, greater individual and societal commitment and more proactive and forceful measured may be needed.

Randomized Controlled Trial Comparative Study Clinical Trial
The cost-effectiveness of a special care unit to care for the chronically critically ill.
To assess the relative value of healthcare programs, technologic innovations, and clinical decisions, policymakers are searching for ways to evaluate cost-effectiveness. What constitutes cost-effectiveness and how should it be measured? The authors discuss ways in which the cost-effectiveness of clinical programs can be measured and describes various methods of assessing both costs and effectiveness. Comparison of the cost-effectiveness of a nurse managed special care unit with that of traditional intensive care units illustrates some of these methods.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient outcomes for the chronically critically ill: special care unit versus intensive care unit.
The purpose of this study was to compare the effects of a low-technology environment of care and a nurse case management case delivery system (special care unit, SCU) with the traditional high-technology environment (ICU) and primary nursing care delivery system on the patient outcomes of length of stay, mortality, readmission, complications, satisfaction, and cost. A sample of 220 chronically critically ill patients were randomly assigned to either the SCU (n = 145) or the ICU (n = 75). Few significant differences were found between the two groups in length of stay, mortality, or complications. ⋯ The average total cost of delivering care was $5,000 less per patient in the SCU than in the traditional ICU. In addition, the cost to produce a survivor was $19,000 less in the SCU. Results from this 4-year clinical trial demonstrate that nurse case managers in a SCU setting can produce patient outcomes equal to or better than those in the traditional ICU care environment for long-term critically ill patients.

Randomized Controlled Trial Multicenter Study Clinical Trial
A trial of goal-oriented hemodynamic therapy in critically ill patients. SvO2 Collaborative Group.
Hemodynamic therapy to raise the cardiac index and oxygen delivery to supranormal may improve outcomes in critically ill patients. We studied whether increasing the cardiac index to a supranormal level (cardiac-index group) or increasing mixed venous oxygen saturation to a normal level (oxygen-saturation group) would decrease morbidity and mortality among critically ill patients, as compared with a control group in which the target was a normal cardiac index. ⋯ Hemodynamic therapy aimed at achieving supranormal values for the cardiac index or normal values for mixed venous oxygen saturation does not reduce morbidity or mortality among critically ill patients.
