BACKGROUND
Urinary tract infections (UTIs) in nursing homes are common, costly, and
morbid.
PURPOSE
Systematic literature review of strategies to reduce UTIs in nursing home
residents
DATA SOURCES
Ovid MEDLINE, Cochrane Library, CINAHL, Web of Science and Embase through June
22, 2015.
STUDY SELECTION
Interventional studies with a comparison group reporting at least one outcome
for: catheter-associated UTI (CAUTI), UTIs not identified as catheter-associated,
bacteriuria, or urinary catheter use.
DATA EXTRACTION
Two authors abstracted study design, participant and intervention details,
outcomes, and quality measures.
DATA SYNTHESIS
Of 5,794 records retrieved, 20 records describing 19 interventions were
included: 8 randomized controlled trials, 10 pre-post non-randomized interventions, and
1 non-randomized intervention with concurrent controls. Quality (range 8-25, median 15)
and outcome definitions varied greatly. Thirteen studies employed strategies to reduce
catheter use or improve catheter care; nine studies employed general infection
prevention strategies (e.g., improving hand hygiene, surveillance, contact precautions,
reducing antibiotics). The nineteen studies reported 12 UTI outcomes, 9 CAUTI outcomes,
4 bacteriuria outcomes, and 5 catheter use outcomes. Five studies showed CAUTI reduction
(1 significantly); nine studies showed UTI reduction (none significantly); 2 studies
showed bacteriuria reduction (none significantly). Four studies showed reduced catheter
use (1 significantly).
LIMITATIONS
Studies were often underpowered to assess statistical significance; none were
pooled given variety of interventions and outcomes.
CONCLUSIONS
Several practices, often implemented in bundles, appear to reduce UTI or CAUTI
in nursing home residents such as improving hand hygiene, reducing and improving
catheter use, managing incontinence without catheters, and enhanced barrier
precautions.
