title: [Analysis of factors conditioning admission at the critical care unit of surgical patients. Prospective study of 764 patients operated for 1 year at a university and reference hospital].
abstract: OBJECTIVE
  Assess what factors determine the income of surgical patients in critical care unit after surgery.
  
  
  METHODS
  It included a survey of the 10% of all patients operated by the services of General Surgery, Thoracic Surgery, Maxillofacial Surgery, Vascular Surgery, Urology and Otolaryngology during 2012. We performed a prospective, observational study. Pre-, intra-, and post-operative variables were analyzed. Comparisons were made between patients operated under elective and emergency surgery, and between patients admitted in critical care and admitted directly in the ward, using χ(2) of Pearson correlation with a confidence interval of 95%.
  
  
  RESULTS
  Seven hundred and sixty-four patients were included into the study, 304 were admitted in critical care after surgery and 460 were admitted in the ward. The medical history showed a statistically significant association with intensive care unit admission, well as the fact of being labeled with a high risk for the risk scales. Complexity and duration of the surgery showed a statistically significant association with intensive care unit admission, as well as the fact of present intra-operative complications. Emergency surgery was not significantly associated with intensive care unit admission of surgical patients, although these patients had significantly higher numbers of intra- and post-operative complications, and more exitus than those undergoing elective surgery.
  
  
  CONCLUSIONS
  A greater incidence of intensive care unit admission of patients undergoing emergency surgery should significantly reduce morbimortality rate. The existence of specific protocols for intensive care unit admission for urgent surgery, and greater availability of beds could be useful in this regard.
