title: [Invasive procedures in patients hospitalized in Spanish internal medicine departments].
abstract: OBJECTIVE
  Invasive procedures (IP) have become routine techniques that benefit an important number of patients on improving their quality of life or avoiding more aggressive treatments. We have conducted a study on the IPs performed in Spanish Internal Medicine (IM) Departments between 2005 and 2009.
  
  
  METHODS
  IP performed to patients admitted to Spanish Internal Medicine departments were analyzed based on the information obtained from the Minimum Basis Data Set (CMBD). IP was defined as the following: filter placement in the inferior vena cava, chest tube placement, biliary, esophageal and colon prosthesis placement, pleurodesis, nephrostomy, external biliary drain placement, gastrostomy tube placement, thoracocentesis and peritoneal catheter placement.
  
  
  RESULTS
  During the study period, a total of 75,853 invasive procedures on 70,239 admittances were performed in 2,766,673 patients (2.5%). IP subjects were younger (68.1 vs 71.4; P<.001), predominantly male (61.9 vs 53.2%; P<.001), with higher mortality (14.6 vs 9.9%; P<.001) and longer stay (18.4 vs 9.6 days; P<0.001). Cost of admittance was clearly higher than the rest of the patients (5,600€ vs 3,835€; P<.001).
  
  
  CONCLUSIONS
  IPs are performed on a low percentage of IM Department hospitalized patients. They are costly, entail high mortality and a longer stay period compared to the mean population admitted to IM. A considerable proportion of the patients receiving IP suffer from neoplastic diseases, frequently in advances stages, which justifies the high inhospital mortality of this population.
