title: [Multiple nosocomial infections in a university hospital].
abstract: BACKGROUND
  Multiple hospital-acquired infections (MHAI) have not been properly evaluated, and therefore data on their leading epidemiological features are lacking. In the present study, MHAI in a university hospital were evaluated during a 5 year period.
  
  
  METHODS
  Data were obtained from the institution program of hospital acquired infection surveillance, which is based on the daily review of microbiological reports with subsequent confirmation of the data in the service where the patient is admitted.
  
  
  RESULTS
  The number of detected MHAI was 1,202 in 522 infected patients, corresponding to 10.3% of the overall number of patients with hospital-acquired infections (HAI). By age groups, the patients over 60 years were the most affected (62.7%), whereas the less affected were those below 40 years (13.6%). By hospital areas, the surgical area had the highest incidence (55.3%) and the gynecological area had the lowest incidence (2.4%). Double infections were the most common ones in all services, with 79.1% of the overall number. The service with the greatest number of patients with MHAI was Surgery (37.9%). Urinary tract infections were the most common type.
  
  
  CONCLUSIONS
  The results show that male surgical patients over 60 years of age were the group at highest risk of MHAI.
