KOURY, Joana Corrêa de A.; LACERDA, Heloísa Ramos and BARROS NETO, Alberto José de. Risk factors associated to mortality on septic patients in an intensive care unit of a general private hospital from Pernambuco. Rev. bras. ter. intensiva [online]. 2007, vol.19, n.1, pp.23-30.

BACKGROUND AND OBJECTIVES: Verify the association between clinical, epidemiological and laboratorial characteristics with mortality of septic patient in an Intensive Care Unit (ICU) from Pernambuco, northeast of Brazil, to improve the attention for patients with sepse which are in risk of developing organ dysfunction. METHODS: Case-control study, without intervention, that included adults' patients admitted in ICU with sepsis or that developed it during ICU stay. RESULTS: It was included 199 patients. After logistic regression, the length of hospital stay more than 72 hours before admission in ICU, evidence of associated co-morbidities, more than three organ failures, and lactate more than 4 mmol/L were associated with mortality. The SOFA score with more than 12 points was associated with precocity mortality (< 72hours). CONCLUSIONS: The septic patients admitted ICU with less than 72h of hospital stay have a better prognosis, and those with a great number of organ failure, and co-morbidities have a superior mortality rate. Between laboratory results, only the high concentration of lactate is associated with mortality.
