Asymptomatic bacteriuria and urinary tract infection in older adults

Clin Geriatr Med. 2007 Aug;23(3):585-94, vii. doi: 10.1016/j.cger.2007.03.001.


Asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) are common in older community dwellers (ages 65 and older) and nursing home residents. The challenge involved in distinguishing ASB from UTI in this population results from other comorbid illnesses that may present with symptoms similar to UTI and from elderly adults who have cognitive impairment not being able to report their symptoms. This article reviews the most updated information on diagnosis, microbiology, management, and prevention of ASB and UTI as they pertain to older community dwellers and nursing home residents.
