Abstract

BACKGROUND:

Escherichia coli bacteraemia rates in the UK have risen; rates are highest among older adults. Previous urinary tract infections (UTIs) and catheterization are risk factors.

AIM:

To examine effectiveness of behavioural interventions to reduce E. coli bacteraemia and/or symptomatic UTIs for older adults.

METHODS:

Sixteen databases, grey literature, and reference lists were searched. Titles and/or abstracts were scanned and selected papers were read fully to confirm suitability. Quality was assessed using Critical Appraisal Skills Programme guidelines and Scottish Intercollegiate Guidelines Network grading.

FINDINGS:

Twenty-one studies were reviewed, and all lacked methodological quality. Six multi-faceted hospital interventions including education, with audit and feedback or reminders reduced UTIs but only three supplied statements of significance. One study reported decreasing catheter-associated UTI (CAUTI) by 88% (F (1,20) = 7.25). Another study reported reductions in CAUTI from 11.17 to 10.53 during Phase I and by 0.39 during Phase II (χ2 = 254). A third study reported fewer UTIs per patient week (risk ratio = 0.39). Two hospital studies of online training and catheter insertion and care simulations decreased CAUTIs from 33 to 14 and from 10.40 to 0. Increasing nursing staff, community continence nurses, and catheter removal reminder stickers reduced infection. There were no studies examining prevention of E. coli bacteraemias.

CONCLUSION:

The heterogeneity of studies means that one effective intervention cannot be recommended. We suggest that feedback should be considered because it facilitated reductions in UTI when used alone or in multi-faceted interventions including education, audit or catheter removal protocols. Multi-faceted education is likely to be effective. Catheter removal protocols, increased staffing, and patient education require further evaluation.
