Sensitivity of the dipstick in detecting bacteremic urinary tract infections in elderly hospitalized patients.

ABSTRACT:

Background

The sensitivity of the dipstick in elderly patients with a suspected urinary tract infection (UTI) is unclear because of the inclusion of patients with urine contamination or asymptomatic bacteriuria in previous studies.

Methods

We selected consecutive patients aged 65 years or older hospitalized in internal medicine departments with bacteremic UTI (same organism in blood and urine cultures) minimizing misclassifications. The false positive rate was determined in consecutive patients with negative culture results. A positive dipstick was a test result with a trace leukocyte esterase and/or nitrite positivity. Bacteriuria was the growth of at least 105 colony-forming units per milliliter of urine.

Results

Of 20,555 consecutive patients, 228 had a bacteremic
