Controlling antimicrobial use and decreasing microbiological laboratory tests for urinary tract infections in spinal-cord-injury patients with chronic indwelling catheters.

Purpose: The effect of replacing the indwelling catheter of patients suspected of having a urinary tract infection (UTI) before collecting a urine sample on the number of organisms isolated in cultures and on drug and microbiology laboratory costs was studied.

Methods: Data were collected for all patients hospitalized in two spinal cord injury (SCI) units between October 2001 and March 2002 who had an indwelling catheter or suprapubic catheter and were suspected of having a UTI. Urine samples were obtained through a port of the indwelling catheter in one SCI unit, while the indwelling catheter was replaced immediately before each urine sample was obtained in the second SCI unit.

Risk factors and mortality associated with Clostridium difficile-associated diarrhoea at a VA hospital.

The objective of this study was to evaluate the risk of certain patient co-morbidities and antibiotics in the development of Clostridium difficile-associated diarrhoea (CDAD). Hospitalized patients developing CDAD during a specified period were compared with a cohort of patients, matched by age, without a diagnosis of CDAD, who were hospitalized during the same time period. Data collection included demographics, hospital ward, co-morbid conditions, antibiotics received, and mortality.
