Asymptomatic Bacteriuria in Adults, Screening, 2019

* Indicates an old grade definition


Recommendations: Screening for Asymptomatic Bacteriuria in Adults

  • Asymptomatic Bacteriuria in Adults, Screening --Pregnant Persons
    Grade: B
    Specific Recommendations:

    The USPSTF recommends screening for asymptomatic bacteriuria using urine culture in pregnant persons.

    Frequency of Service:

    In general, screening is performed once at the first prenatal visit per clinical guidelines. However, there is little evidence on the optimal timing and frequency of screening for asymptomatic bacteriuria in pregnancy.2  . Screen pregnant persons for asymptomatic bacteriuria using a midstream, clean-catch urine culture at the first prenatal visit or at 12 to 16 weeks of gestation, whichever is earlier. A urine culture showing >100,000 CFU/mL of a single uropathogen or >10,000 CFU/mL if the pathogen is group B streptococcus indicates treatment.

    Risk Factor Information:

    This recommendation applies to adults 18 years and older and pregnant persons of any age without signs and symptoms of a urinary tract infection. It does not apply to persons who have chronic medical or urinary tract conditions, such as end-stage renal disease; have indwelling urinary catheters, urinary stents, or spinal cord injuries; are hospitalized; reside in an institution (eg, a nursing home); or who are transplant recipients.

     

    The risk of developing asymptomatic bacteriuria varies by age, sex, and pregnancy status.6 Because of the location and length of the female urethra, women are predisposed to infections of the urinary tract, including asymptomatic bacteriuria.5 Physiologic changes in both pregnant and older women increase the risk of asymptomatic bacteriuria and a urinary tract infection.71112 In general, men are at low risk of developing asymptomatic bacteriuria, although rates increase with older age.12 Persons with diabetes are also at increased risk of developing asymptomatic bacteriuria.46

  • Asymptomatic Bacteriuria in Adults, Screening -- Nonpregnant Adults
    Grade: D
    Specific Recommendations:

    The USPSTF recommends against screening for asymptomatic bacteriuria in nonpregnant adults.
