Introduction. Nebulized devices are commonly used in the treatment of respiratory infection, and other respiratory diseases. It has been reported nosocomial infections in cystic fibrosis patients as a result of the use of contaminated devices. However, little is known about nosocomial infections secondary to aerosolized therapy in COPD patients admitted for acute exacerbation.
Methods. Thirty consecutive patients (13 males) were included. All of them received aerosolized medication.  Each patient used their own facemask and nebulizer cup, which were stored in the room after its use. Samples from nebulizer cups were obtained on days 0, 4 and 7. In addition, sputum samples were obtained on day 0 (prior to any nebulization) and on day 7, and cultivated in enriched media.
Results. Only nine nebulizer cups had positive microbiological cultures. Coagulase negative staphylococci (CoNS) were isolated in all cases. Sputum samples could be obtained in 27 patients. None grew CoNS after 7 days of aerosolized therapy. Gram-negative non-fermenting bacilli were isolated in three patients without concomitant grown in nebulizer cups.
Conclusions. We did not find any nosocomial infection related to aerosolize medications in COPD patients admitted for acute exacerbation.

Duration of antimicrobial therapy     

                        
JUAN PASQUAU, MAYRA MATESANZ              

The management of infectious diseases is always complex, not only because of its high incidence and mortality, but the difficulty of designing effective treatments that minimize the development of bacterial resistance in the clinical setting. One of the most important options is the reduction of exposure to antibiotic treatment, optimizing by desescalation and shortening the duration of therapy.

Objectives. Antibiotic treatment is vital in patients with severe sepsis/septic shock. The objectives were to assess the degree of concordance between antibiotic prescribed in emergencies and post requirements; to relate it to health outcomes (mortality) and to analyze the reasons for disagreement.
Material and methods. Retrospective descriptive study of antibiotic treatment prescribed in emergencies and the subsequent treatment in patients with criteria of severe sepsis/septic shock in 2013. We collected patient demographic characteristics, infectious focus, antibiotic prescribed from emergencies and subsequent changes. It was considered concordant if there were no changes, if there were changes, but the initial antibiotic was right and suspensions for end of treatment. Mortality and evolution were analyzed.
Results. Six hundred patients were included. A 60% experienced changes respect to the antibiotic treatment initiated in emergencies (87.6% justified), with a degree of overall antibiotic concordance of 47.5% The mortality rate at end-point was 9.83%, with no statistically significant relationship with the degree of concordance (OR=0.864 (0.503-1.484)/χ2=0.28; p=0.597). Reasons for change of antibiotic:  clinical outcome (17.96%), change of spectrum (35.03%), de-escalation (41.32%), sequential therapy (8.68%). An 11% required ICU admission. Clinical outcomes: resolution of the disease (79.2%), readmission after 30 days (7.7%) and transfer to health centers (4.5%). The median hospital stay was 7 days.
Conclusions. The degree of concordance antibiotic was quite high, and the mortality rate was lower than that described in the literature, without relating to the discordance. The presence of concordance was associated with fewer readmissions and ICU admissions. The main reasons for disagreement were inadequate spectrum selection and change after microbiological crops.
