Table 3. Distribution, initiation of treatment and in-hospital mortality of patients colonized or infected with carbapenem-resistant MDR-GNB.

Sample category	Likelyhood for infection	n of pts (% total)	treated for infection, n of pts (%)	in-hospital mortality (%)
blood cultures	very high	11 (9,2%)	10 (90,9%)	81,8%
intraoperative swabs, tissue biopsies	high	7 (5,9%)	5 (71,4%)	71,4%
respiratory samples (TS, BAL, and sputum)	equivocal	58 (48,7%)	28 (48,3%)	27,6%
superficial swabs (wound swabs, ulcus swabs)	low	9 (7,6%)	0 (0,0%)	0,0%
routine screening swabs (nasal, rectal)	very low	34 (28,6%)	7 (20,6%)	29,4%

Patients were stratified by the sample category from which carbapenem-resistant MDR-GNB were obtained. Patients in whom MDR-GNB were isolated from more than one specimen were counted once in the category with the highest likelihood for infection. Abbreviations: n of pts, number of patients; TS, tracheal secretion; BAL, bronchoalveolar lavage
