PALLARES, Christian José  and  MARTINEZ, Ernesto. Implementation of a regulated antibiotic use program in two medical-surgical intensive units care in a third level mayor teaching hospital in Colombia. Infect. [online]. 2012, vol.16, n.4, pp.192-198. ISSN 0123-9392.

Objective: To determine the impact of a Program of Regulated Use of Antibiotics in adherence, antibiotic use and bacterial resistance in two medical-surgical Intensive Units Care (ICU´s) in a third level mayor teaching hospital in Colombia. Materials and Methods: Prospective observational study of intervention that examines two time periods in two ICU: pre-intervention (august/2008 to February/2009) and post-intervention (march to September/2009). The study was carried out in the Hospital Universitario del Valle Evaristo García E.S.E. (H.U.V). We evaluated adherence to the antibiotic therapy guidelines established by Hospital Epidemiology, antibiotic use measured by Defined Daily Doses and monthly incidence of infection by ESBL producer E.coli and K.pneumoniae, P.aeruginosa fluoroquinolone and four generation cephalosporin resistant, oxacilin resistant S.aureus and multidrug resistant A.baumannii. Results: The adherence to the antibiotic guidelines of antibiotic use was greater to 80% for the both ICU during the intervention period. Antibiotic use was significantly reduced for meropenem (ICU1 p=0,009/ICU2 p=0,000), vancomycin (ICU1-ICU2 p=0,018), ceftriaxone (ICU1 p=0,015/ICU2 p=0,018), ciprofloxacin (ICU1 p=0,027/ICU2 p=0,018), and increased the used of piperacilin/tazobactam (ICU2 p=0,017), and cefepime (ICU1 p=0,028/ICU2 p=0,004). The incidences of infection by ESBL producer E.coli and K.pneumoniae (ICU1 83%/ ICU2 78%), ciprofloxacin resistant and four generation cephalosporin resistant P.aeruginosa (ICU1 87%/ ICU2 82%) and (ICU1 83%/ICU2 76%) ware also reduced. Conclusions: The implementation of a Program of Regulated Use of Antibiotics reduces antibiotics use and resistant micro-organism specific infection rate in the Hospital Universitario del Valle´s ICU.
