XXXX in a respiratory intensive care unit.

@entity1 @entity794 @entity281 @entity325 @entity580 @entity204 @entity130
A total of 250 consecutive admissions to an open-plan respiratory ICU were analyzed prospectively to identify the incidence of secondary hospital-acquired @entity281 and possible predisposing factors. Despite preventative measures and a restricted antibiotic policy, 23.6% of @entity1 developed secondary @entity281 . @entity1 admitted after multiple @entity130 were the only diagnostic category of @entity1 who showed a significantly increased incidence of secondary @entity281 . The length of hospitalization and number of @entity1 who had intubations or tracheostomies was higher in the group with @entity325 ; the causal relationship was difficult to establish. @entity1 who were not intubated or tracheostomized did not develop @entity325 . Prior administration of antibiotics did not appear to influence the incidence of @entity325 . There was a significant increase in secondary @entity281 in @entity1 with a higher therapeutic intervention scoring system score. The predominant pathogens cultured were highly resistant Gram-negative organisms, particularly Acinetobacter sp. and Pseudomonas sp. @entity794 was the most common Gram-positive pathogen. The ICU course was probably prolonged by the complication of @entity580 , which may have contributed to the @entity204 .
