A small study at just one urban emergency room — showed that it over diagnosed women with urinary tract infections (UTIs) — by roughly two fold — and significantly underdiagnosed sexually transmitted infections (STIs) in the same patients — by about 37 percent — The failure to bacteriologically culture urine apparently contributed to these mistakes Comments Off on A small study at just one urban emergency room — showed that it over diagnosed women with urinary tract infections (UTIs) — by roughly two fold — and significantly underdiagnosed sexually transmitted infections (STIs) in the same patients — by about 37 percent — The failure to bacteriologically culture urine apparently contributed to these mistakes
