Therapy vs no therapy for bacteriuria in elderly ambulatory nonhospitalized women.
This prospective randomized study was undertaken to determine the efficacy of antimicrobial therapy compared with no therapy for bacteriuria in elderly ambulatory nonhospitalized women. Sixty-one women (mean age, 85.8 years) with bacteriuria were in the no therapy control group and 63 women (mean age, 85.8 years) with bacteriuria were in the therapy group; none had symptoms of urinary tract infection. One short course of antimicrobial therapy achieved a cure rate of 68.3% (43 of 63 women cured) two weeks after treatment. During the six-month follow-up period, ten (16.4%) of 61 women in the no therapy group and five (7.9%) of 63 women in the therapy group developed symptomatic urinary tract infection. At the time of six-month follow-up, 19 (34.5%) of 55 women in the no therapy group and 35 (63.6%) of 55 women in the therapy group did not have bacteriuria. We conclude that for asymptomatic bacteriuria in elderly ambulatory nonhospitalized women, short-course antimicrobial therapy is effective at two-week follow-up and that antimicrobial therapy can eliminate bacteriuria in most of these women for at least a six-month period.
