Critical stroke patients are characterized by high severity of illness, elevated resource consumption, and poor outcomes that are mainly influenced by severity and age. Glasgow Coma Score-measured neurological severity is the main determinant of future functional capacity, which is greater at 1 year.

TCT detects more chest injuries in trauma patients than does CXR and induces therapy changes in a considerable number of patients. However, this does not translate into an improvement in clinical outcomes.

The 6-yr mortality of patients with chronic obstructive pulmonary disease requiring ICU admission is high. Mortality is mainly influenced by pre-ICU admission QOL. At 6 yrs, at least 15% are alive; survivors have a worse QOL compared with pre-ICU admission, although three quarters of them are self-sufficient.

This study analyzed the effect of both positive end-expiratory pressure (PEEP) and reduction in tidal volume (VT) on extravascular lung water (EVLW) in a permeability model of pulmonary edema. Immediately after producing a pulmonary edema with oleic acid, 21 pigs were randomized into three groups. Group I (n = 8): PEEP of 0 cm H2O (ZEEP), VT of 12 ml/kg; Group II (n = 6): PEEP of 10 cm H2O, VT of 12 ml/kg; Group III (n = 7): PEEP of 10 cm H2O, VT of 6 ml/kg. EVLW was measured by the double indicator method (DI) at baseline (time 0) and after 30, 60, 120, 180, and 240 min and by the gravimetric method (G) at 240 min. Both methods correlated excellently (r = 0.94, p < 0.0001). EVLW-DI was significantly less with PEEP application (Group II versus Group I) at 180 min and thereafter. Likewise, EVLW-DI was less throughout the experimental period with reduced VT once PEEP was applied (Group III versus Group II). EVLW-G was less in Group II than in Group I at 16.3 +/- 2.7 and 23.2 +/- 4.2 ml/kg, respectively (p < 0.0001), and less in Group III than in Group II at 10.7 +/- 0.9 and 16.3 +/- 2.7 ml/kg (p < 0.0001). We conclude that early application of 10 cm H2O of PEEP reduces EVLW in permeability pulmonary edema. The lowering of VT reduced EVLW even further.

In Spain, the quality of life of critically ill patients before their ICU admission is good, and only a small proportion of patients have a low quality of life before admission. Previous quality of life is related to hospital mortality rate but contributes very little to the discriminatory ability of the APACHE III prediction model and has little influence on ICU resource utilization as measured by length of stay and therapeutic activity.

There is a strong correlation between TISS 28 and TISS 76 scores in the PAEEC database and TISS 28 works correctly in our setting.

We have customized the APACHE III mortality prediction system for the Spanish population. This adapted model has demonstrated the requisite validation, calibration, and discrimination for its use among Spanish critical care patients.
