Clinical Investigations in Critical CareShock on Admission Day Is the Best Predictor of Prolonged Mechanical Ventilation in the ICU

Materials and Methods
This retrospective cohort study took place in an eight-bed, mixed medical-surgical ICU in a university-affiliated hospital in La Plata, Buenos Aires, Argentina. Patients were admitted to the hospital from November 1, 1999, to October 31, 2002, and received MV for > 12 h. Patients were included only if intubation was performed in our ICU or in the operative room within a few hours after ICU admission. All data on these patients were prospectively collected as part of our ICU database.

Results
During the 3 years of our study, 551 patients were admitted to the ICU. Their mean age was 41 ± 17 years (± SD); 53% were men. Mean APACHE II and SAPS II scores were 18 ± 9 and 32 ± 18, respectively. The expected mortality rates were 31% and 28%, respectively, and the observed mortality rate was 31%.
Of the entire cohort, 348 patients (63%) received MV, and 319 patients (58%) received MV for > 12 h. Median length of MV was 7 days (interquartile range [IQR], 2 to 19 days). One hundred thirty
Discussion
As critical care is acutely directed at reversing a life-threatening condition, mortality is considered to be the primary outcome measure. However, morbidity outcomes also are relevant to patients, their families, health-care providers, and society as a whole. Recently, the importance of patient-centered outcomes has been emphasized, and long-term outcomes are considered important measurements.1314 The duration of MV, which is an indicator of serious health complications and significantly
