serious adverse events associated with not processing urine culture

Rate of serious adverse events in patients without symptoms who did and did not have urine specimens processed

Rate of serious adverse events due to antibiotic therapy in patients who received antibiotics for asymptomatic bacteriuria

Proportion of patients with symptomatic urinary tract infection (UTI) who did not respond to initial empiric antibiotics

individual patient data will not be available to other researchers. This is a quality improvement study

Pre-treatment Urine culture will be done then all patients will receive empirical 3 gm oral phosphomycin fosfomycin will be taken by mouth on an empty stomach i.e. 2-3 hours after meals preferably in the evening before bed time after emptying the bladder.
The contents of 1 packet of Monuril will be dissolved in a glass of water or another non-alcoholic drink and drink immediately. Do not mix with hot water. Do not take fosfomycin in its dry form.
Response to treatment will be assessed by post-treatment urine culture.

Pre-treatment Urine culture and antimicrobial sensitivity testing will be done then all patients will receive oral culture specific antibiotic therapy in the form of five days regimen.
Response to treatment will be assessed by post-treatment urine culture.

Urinary Tract Infection

Single dose 3 gm oral fosfomycin will be taken by mouth on an empty stomach

phosphomycin

Culture-specific antibiotic treatment for 5 days

Culture specific antibiotic therapy

Mid-stream urine sample will be cultured and number of CFU per mL will be determined.

Pre-treatment Urine Culture

Susceptibility of urinary pathogens to various antimicrobials

Antimicrobial sensitivity testing

the Use of Fosfomycin as a Single Dose Oral Treatment of Asymptomatic Bacteriuria

Empirical Use of Fosfomycin as a Single Dose Oral Treatment of Asymptomatic Bacteriuria

Decline in colony forming unit (CFU)/mL or absence of bacterial growth after treatment

Either extending the course of treatment into 5 or 7 days regimen or changing the antibiotic in case of inadequate initial response.

Need for urine culture and sensitivity in fosfomycin group in case of inadequate response on empirical treatment.
