Multicenter Study Clinical Trial
The SUPPORT prognostic model. Objective estimates of survival for seriously ill hospitalized adults. Study to understand prognoses and preferences for outcomes and risks of treatments.
To develop and validate a prognostic model that estimates survival over a 180-day period for seriously ill hospitalized adults (phase I of SUPPORT [Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments]) and to compare this model's predictions with those of an existing prognostic system and with physicians' independent estimates (SUPPORT phase II). ⋯ A limited amount of readily available clinical information can provide a foundation for long-term survival estimates that are as accurate as physicians' estimates. The best survival estimates combine an objective prognosis with a physician's clinical estimate.

Relationship between blood lactate concentrations and ionized calcium, glucose, and acid-base status in critically ill and noncritically ill patients.
To determine the relationships between circulating blood lactate concentrations and several biochemical variables including ionized calcium, glucose, pH, and acid-base status in critically ill and noncritically ill patients. ⋯ a) There is neither a statistically significant nor clinically relevant relationship between whole blood lactate concentrations and ionized calcium concentrations when studying patients with or without hyperlactatemia. b) Although there is a statistically significant correlation between circulating lactate concentrations and blood glucose concentrations, arterial pH or arterial base deficit, such associations do not appear to be clinically important.

A survey of interhospital transport of the critically ill child in the United Kingdom.
Nineteen paediatric intensive care units were surveyed by questionnaire to provide information on the number of interhospital transfers, the experience of personal accompanying the critically ill child and the equipment available to maintain intensive care during transfer. Replies were received from 17 units. ⋯ Most respondents believed that existing arrangements for transfer were unsatisfactory, but only four units said that transfer may be prevented or delayed by lack of facilities. We believe that any plan to centralize paediatric intensive care in the UK should also include the means by which to transfer the patient without increasing the risk to the patient.

Subjective psychological status of severely ill patients discharged from mechanical ventilation.
To evaluate psychological status in consecutive survivors of ICU who needed mechanical ventilation (MV). ⋯ These results showed that psychological status is poor in ventilated ICU patients, which should be considered in their care.

[Evaluation of the prognosis of critically ill surgical patients by APACHE II score system].
A prospective trial was conducted in 386 critically ill surgical patients, the APACHE II score was used to quantify the severity of illness and to judge the outcome. Admission APACHE II score of these patients averaged 15.6 +/- 5.4, the mortality rates rose from 1.9% to 100% when the APACHE II score increased from 0 to 38. The score was closely correlated with the subsequent risk of hospital death for these patients (r = 0.75 P < 0.001). Critically ill surgical patients would be well served by APACHE II for quality assurance or outcome.
