Women with acute uncomplicated urine infection are usually treated with antibiotics. One trial has demonstrated that delayed antibiotic treatment offered without symptom relief results in a modest reduction in antibiotic use. There is some evidence that ibuprofen provides symptom relief and reduces antibiotic use. Uva-ursi, a herbal product, has a traditional use for urinary infection symptom relief. We set out to test: in adult women with suspected UTI who accept the delayed prescription strategy: Do NSAIDs or uva-ursi (a herbal product) provide relief from urinary symptoms and reduce antibiotic use.
Adult women with suspected urinary tract infection presenting to primary care will be randomised using a factorial trial design in which patients will be randomised to one of two interventions as below:
Group 1 – Uva-ursi + advice to take ibuprofen
Group 2 – Placebo + advice to take ibuprofen
Group 3 – Uva-ursi + no advice to take ibuprofen
Group 4 – Placebo + no advice to take ibuprofen
Patients and physicians will be blinded to the randomised group for the herb.
The main outcome is symptom severity at days 2–4 recorded in a validated, self-report diary used in previous studies.
Secondary outcomes include antibiotic use and symptom duration.
In total the trial will require 328 patients in order to achieve at least 90% power for the primary endpoint and 80% for the secondary endpoint.
In accordance with CONSORT guidelines all comparative analyses will be conducted on an intention-to-treat basis using SPSS or similar package.
The outcomes from this trial have the potential to modify the current approach to the management of acute urinary symptoms with less dependence on the use of antibiotics.
