Multicenter Study Clinical TrialDescription of various types of intensive and intermediate care units in France. French Multicentric Group of ICU Research.
The types of intensive care are multiple. The aim of this multicentric study was to describe activity of different ICUs using the same methods. 38 ICU were chosen by cooption, not randomization. Collected data concerned input (age, previous health status (HS), Simplified Acute Physiology Score or SAPS, Intensive Care Group (ICG), processes (TISS points), percentage of ventilated patients and pulmonary arterial lines and outcome (ICU death rate). ⋯ Surgical patients had better previous health status, were younger and scheduled for 40%. TISS points were higher, mainly by a higher rate of ventilated patients and patients with pulmonary artery lines on the first day. Specialized units characteristics depended mainly on the ICG.(ABSTRACT TRUNCATED AT 250 WORDS)

We monitored the response to intensive care of 480 patients by calculating the difference in their organ failure score on the day of admission and that on the day of discharge, and related the response to hospital outcome. The patients were classified into: A) those who benefited (33%), B) those who might have benefited (28%), C) those who would never or would no longer have benefited (18%) and D) those who did not require intensive care management (21%). ⋯ Group C patients used up 26.8% of the total intensive care unit bed days, while group D patients occupied 3.7%. We concluded that an acute terminal care unit to care for group C patients who have no hope of survival is more appropriate to the needs of our hospital than an intermediate care unit for overnight monitoring of uncomplicated postoperative and non-operative patients (group D).

Impedance cardiography has not achieved popularity in the Intensive Care Unit (ICU) to date probably because of the limitations in technique and interpretation associated with the altered physiology of critically ill patients, and also because of interference from other machinery in the ICU. The current climate of questioning the existing technology for bedside cardiovascular assessment however spurs the need to evaluate impedance cardiography as a noninvasive alternative. Validation in noncritically ill patients is good when compared to other technologies (e.g., thermodilution, Fick, dye dilution (r greater than 0.9)). ⋯ This is thought to be a measure of contractility that is independent of preload and afterload. The ultimate test in the ICU for impedance cardiography is whether clinical outcome of critically ill patients is altered by the use of this technology. Such outcome testing is essential before the true value of impedance cardiography in the management of critically ill patients can be determined.

This article details the development of an instrument designed to assess the impact of certain environmental stressors in the pediatric intensive care unit (ICU) on parents of hospitalized children. A theoretical framework based on stress theory and developed by the authors provided the framework for this project. This 62-item scale assessing seven dimensions of the PICU environment was developed in three stages. ⋯ In the third phase of the project, the revised instrument was administered to 510 parents while their children were in one of five pediatric ICUs. Factor analysis provided seven orthogonal, invariant factors. An alpha coefficient of .95 was obtained for the total instrument; subscale coefficients ranged from .72 to .99 providing support for internal consistency and construct validity.

Comparative Study
Outcome from intensive care. I. A 5-year study of 1308 patients: methodology and patient population.
During a 5-year period, from 1979 to 1983, demographic and disease-related data were collected prospectively on 1308 adult patients from 1555 admissions to a multidisciplinary intensive care unit (ICU) in a Danish university hospital. The patients were followed during the stay in ICU, the ensuing hospital stay, and up to 8 years after discharge from hospital. The male: female ratio was 1:1. ⋯ The APACHE- and TISS-systems were simultaneously applied to a representative sample of 216 consecutive admissions. The average APACHE score was 14.9 +/- 8.2 and the average TISS score 28.3 +/- 11.1 points. The ICU patients presented in this paper do not differ much from ICU patients in other outcome studies.
