Pediatric UTI Controversies20 December, 2012 by: colinparker
So, you thought it was straightforward: suspect UTI, diagnose UTI, treat UTI…
And let someone else worry about the follow-up.
Unfortunately, we work in a fragmented system, where we need to kick-start the correct follow-up for our patients, who may otherwise miss out if we don’t get them on the right track before they leave the Emergency Department.
We used to be paranoid about investigating Urinary Tract Infection in children. Some of us still are, some of us are less worried, while some of us have not yet realised that kids are different, and are unaware that the Pediatricians out there have been aggressively investigating UTIs in kids for decades. Maybe we can stop trying to educate and inform these laggards now?
Although the evidence is far from complete, the landscape of pediatric UTI is definitely changing, and the discussion is driving a less aggressive approach to investigating and following up UTI in children. But are we swinging too far in the other direction?
Join us on a tour of the literature, and decide for yourself…
UTI Controversies PEMcast – Outline
[cp] Hello, disclaimer, introduction
Common clinical problem, significant consequences if missed – some debate about this more recently.
Not clear what pre-requisites are for renal scarring – whether genetic predisposition, related to timing of infection and treatment, severity of infection.
Not clear whether renal scarring is preventable by a strategy of aggressive treatment and investigation.
Both the treatments and investigations come with associated risks, discomfort, and costs.
[AH] Controversies include:
- When to treat with IV ABs
- How long to treat
- When to give prophylactic antimicrobials
- Utility of proof-of-cure urine test
- Who to investigate
- How to investigate
- Treatment of VUR
…because of a relative lack of RCT evidence.
[cp] Ideally we need to balance risks and costs of any tests/interventions against the likelihood of benefit to the patient, aiming to achieve ‘greatest good for the greatest number’ with our resources (or: spend more money to prevent any adverse outcomes).
We will not be able to definitively answer these questions, but aim to give a representative cross-section of opinion and a small amount of science to inform the debate…
