title: Factors associated with increased mortality and prolonged length of stay in an adult intensive care unit.
abstract: OBJECTIVE
  The intensive care unit is synonymous of high severity, and its mortality rates are between 5.4 and 33%. With the development of new technologies, a patient can be maintained for long time in the unit, causing high costs, psychological and moral for all involved. This study aimed to evaluate the risk factors for mortality and prolonged length of stay in an adult intensive care unit.
  
  
  METHODS
  The study included all patients consecutively admitted to the adult medical/surgical intensive care unit of Hospital das Clínicas da Universidade Estadual de Campinas, for six months. We collected data such as sex, age, diagnosis, personal history, APACHE II score, days of invasive mechanical ventilation orotracheal reintubation, tracheostomy, days of hospitalization in the intensive care unit and discharge or death in the intensive care unit.
  
  
  RESULTS
  Were included in the study 401 patients; 59.6% men and 40.4% women, age 53.8±18.0. The mean intensive care unit stay was 8.2±10.8 days, with a mortality rate of 13.5%. Significant data for mortality and prolonged length of stay in intensive care unit (p <0.0001), were: APACHE II>11, OT-Re and tracheostomy.
  
  
  CONCLUSIONS
  The mortality and prolonged length of stay in intensive care unit intensive care unit as risk factors were: APACHE>11, orotracheal reintubation and tracheostomy.
