STUDY OBJECTIVE: Obese patients seem to have worse outcomes and more complications during intensive care unit (ICU) stay. This study describes the clinical course, complications and prognostic factors of obese patients admitted to an intensive care unit compared to a control group of nonobese patients. DESIGN: Retrospective observational study. SETTING: A 10-bed adult intensive care unit in a university-affiliated hospital. METHODS: All patients admitted to the intensive care unit over 52 months (April 01/2005 to November 30/2008) were included. Obese patients were defined as those with a body mass index (BMI) ≥ 30 Kg/M2. Demographic and intensive care unit related data were also collected. An clinical and demographical matching group of eutrophic patients selected from the data base as comparator for mortality and morbidity outcomes. The Mann-Whitney test was used for numeric data comparisons and the Chi Square test for categorical data comparisons. RESULTS: Two hundred nineteen patients were included. The obese group (n=73) was compared to the eutrophic group (n= 146). Most of this group BMI ranged between 30 - 35 Kg/M2. Only ten patients had body mass index ≥40 Kg/M2. Significant differences between the obese and eutrophic groups were observed in median APACHE II score (16 versus 12, respectively; p<0.05) and median intensive care unit length of stay (7 versus 5 days respectively; p<0,05). No significant differences were seen regarding risk of death, mortality rate, mechanical ventilation needs, days free of mechanical ventilation and tracheostomy rates. The observed mortality was higher than the APACHE II-predicted for both groups, but the larger differences were seen for morbid obese patients (BMI ≥40 Kg/M2). CONCLUSIONS: Obesity did not increase the mortality rate, but improved intensive care unit length of stay. The current prognostic scoring systems do not include BMI, possibly underestimating the risk of death, and other quality of care indexes in obese patients. New studies could be useful to clarify how body mass index impacts the mortality rate.

BACKGROUND AND OBJECTIVES: Searching the literature, we found no studies which correlate the NAS (Nursing Activities Score), who determines the real time of nursing evaluation and patient care, with mortality for prognostic index. The objectives this study were to know the values of the NAS score at ours service, try to find correlations between this values and the APACHE II index and to analyze the mortality rates with NAS scores. METHODS: This is a prospective ICU inpatient study from July to November/2005. Our data's of the APACHE II score were recorded from the QuaTI system study. Qui-square test or equivalent was done to compare the proportions. For the analyses we utilized the EPI-INFO-6 software. RESULTS: The sample was 148 patients, mean age of 55.5 years with 59.4% males. The mean hospitalization time were 9.1 days, mortality rate of 29.7%, mean NAS score of 51.5% and mean APACHE II score of 13.4. There were a positive correlation ship between NAS and APACHE II index (R = 0.82). Selecting only the patients with NAS more than 51 we found that 41 in 83 died and 42 in 83 survived. Those whose NAS were under 51, only 3 in 65 died and 62 in 65 survived (p < 0.005), identifying an statistically significant group. CONCLUSIONS: In this study the mean value of NAS were 51.5%. There were good correlation with the APACHE II index and we shown that the mortality rate was high in the higher NAS values.

BACKGROUND AND OBJECTIVES: To assess the incidence of tracheostomy in patients submitted to mechanic ventilation (MV); to compare the length of stay (LOS), duration of MV, APACHE II and mortality among patients submitted to tracheostomy, according to the moment of its application (early or late). METHODS: A retrospective observation study type cohort was done from April thru October 2005 including 190 patients at the adult intensive care unit (ICU) of Hospital Estadual do Grajaú. RESULTS: Among the 190 patients, 32 (16.84%) were submitted to tracheostomy with a longer LOS (30.16 days) as compared to those that were not (p < 0.001). The mean time of the tracheostomy procedure was 13.5 days from the starting of the MV. It is known that there still is no guidance for defining an ideal period for the operation. On this study, the prevalence of early tracheostomy (<13 days) was 46.87% (n = 15) and the late tracheostomy (> 13 days) was 53.13% (n = 17). In a meaningful way, the patients with early tracheostomy obtained APACHE II superior to those with late tracheostomy (18.2 versus 13.47), however there was no difference regarding the mortality rate. There was no difference regarding the time of ICU LOS (28.9 versus 31.28 days) and the MV time (29.73 versus 32.23 days) for both groups. CONCLUSIONS: The incidence of tracheostomy was high, being associated to a smaller ICU mortality but with a longer LOS and more complications. There was no significant difference regarding the destination of the patients when submitted to early or late tracheostomy.
