Abstract

OBJECTIVE:

To test whether active management of urinary tract infections (UTI) in young children by general practitioners can reduce kidney scarring rates.

DESIGN:

A comparison of two audits in Newcastle, of children aged <8 years, presenting with UTIs ; a retrospective audit of conventional management during 1992-1995 (1990s) versus a prospective audit of direct access management during 2004-2011 (2000s).

MAIN OUTCOME MEASURES:

Kidney scarring rates, and their relationship with time-to-treat.

RESULTS:

Children with a first UTI in the 2000s compared to those in the 1990s, were referred younger, were half as likely to have a renal scar (girls OR 0.47, 95% CI 0.29 to 0.76; boys 0.35, 0.16 to 0.81), and were about 12 times more likely to have vesicoureteric reflux without scarring (girls 11.9, 4.3 to 33.5; boys 14.4, 4.3 to 47.6). In the 2000s, general practitioners treated about half the children at first consultation. Children who were treated within 3 days of their symptoms starting were one-third as likely to scar as those whose symptoms lasted longer (0.33, 0.12 to 0.72).

INTERPRETATION:

Most kidney defects seen in children after UTIs, are acquired scars, and in Newcastle, active management in primary care has halved this rate.
