Don’t recommend antimicrobials to treat bacteriuria in older adults unless specific urinary tract symptoms are present.

Signs and symptoms suggestive of urinary tract infection (UTI) are increased frequency, urgency, pain or burning on urination, supra-pubic pain, flank pain and fever. Dark, cloudy and/or foul-smelling urine may not be suggestive of UTI but rather of inadequate fluid intake. Cohort studies have found no adverse outcomes associated with asymptomatic bacteriuria for older adults. Not only does antimicrobial treatment for such bacteriuria in older adults show no benefits, it increases adverse antimicrobial effects. Consensus criteria have been developed for the specific clinical symptoms that (when associated with bacteriuria) define UTI. Exceptions to these criteria include recommended screening for and treatment of asymptomatic bacteriuria before urologic procedures where mucosal bleeding is anticipated. If a nurse caring for a patient feels that medication is not the appropriate intervention, the nurse has a responsibility to discuss these concerns with the prescribers.
