Outcome:
325 papers were found on Medline, of these one was a recent systematic review which included all those papers identified as answering the 3 part question, found also in Cochrane
Relevant Paper(s):
| Study Title | Patient Group | Study type (level of evidence) | Outcomes | Key results | Study Weaknesses |
|---|---|---|---|---|---|
| Short versus standard duration oral antibiotic therapy for acute urinary tract infection in children (Review) Michael M, Hodson EM, Craig JC, Martin S, Moyer VA 2003, Issue 1 UK | Children older than 3 months and younger than 18 years with culture proven UTI | Systematic review and meta-analysis | Difference in frequency of positive urine cultures between the short (2-4 days) and standard duration oral antibiotic therapy (7-14 days) for UTI in children at 0-10 days after treatment | 8 studies: RR 1.06; 95% CI 0.64 to 1.76 | The authors themselves mention limitations associated with the primary studies included in the review. These include: lack of relevant information with regards to critical care, no information about how long it took for symptoms to subside after starting the antibiotics, and if recurrance of UTI was associated with any clinical features. |
| Difference in frequency of positive urine cultures between the short (2-4 days) and standard duration oral antibiotic therapy (7-14 days) for UTI in children at 15 months after treatment | 10 studies: RR 0.95; 95% CI 0.70 to 1.29 | ||||
| Difference between short and standard duration therapy in the development of resistant organisms in UTI at the end of treatment | 1 study: RR 0.57, 95% CI 0.32 to 1.01 | ||||
| Difference between short and standard duration therapy in the development of resistant organisms in recurrent UTI | 3 studies: RR 0.39; 95 CI 0.12 to 1.29 |
Author Commentary:
This review addresses the three-part question directly and concludes that a short course of treatment is an effective choice in the treatment of childhood UTI.
Bottom Line:
A short 2-4 day course of antibiotics is a reasonable treatment option for UTI in children.
