Abstract [en]

Background and aims: Bacterial resistance to antibiotics hasemerged as an important factor influencing patient mortalityand morbidity. The overall purpose of this project is to exam-ine the impact of bacterial resistance on resource use andoutcome in the critically ill. The aims of the current report isto demonstrate that linkage of local microbiology databasesand the Swedish Intensive Care Registry (SIR) was possibleand to provide a preliminary analysis of data from a sub-group of ICU patients (chronic obstructive pulmonary dis-ease, COPD).

Methods: Admissions due to an acute exacerbation of COPDwere matched with bacteriology samples obtained 14 daysbefore ICU admission, during ICU stay and 14 days after dis-charge from ICU by linking six local microbiology databaseswith patient data in SIR. Linkage was by the patient’s uniquepersonal number and ICU admission and discharge days.

Results: We found 195 patients with median APACHE II prob-ability 0.22 (iqr 0.12–0.37), median length of stay (LOS) 46 (iqr 21–125) hours and 79% 30 day survival. Cultures from 2 weeks before (n=128), during ICU-stay (n=750) and from14 days after ICU discharge (n=228) were identified. During ICU stay airways (n=261), blood or intravascular devices (n=246) and other sites (n=243) were cultured. The totalnumber of airway cultures per patient increased linearly withlength of stay (P<0.01,r2= 0.61). Gram-negative bacteria were most common in positive airway cultures (41%) followedby Candida spp (22%), while positive blood cultures were pre-dominantly Gram-positive (71%). 30-day-mortality was 10/53 with positive and 10/29 with negative airway cultures(P=0.23).

Conclusion: Linkage of local microbiology databases and theSwedish Intensive Care Registry is possible and can generate information that may be used to examine relationships between bacterial resistance and outcomes in the critically illpatient.
