Highlights
- •Stroke severity plays a large role in developing urinary tract infections.
- •Urinary tract infections after stroke may prolong length of stay and increase costs.
- •Post-stroke urinary tract infection does not significantly impact long term outcome.
Abstract
Background
Urinary tract infection (UTI) is one of the most common infections seen in patients
hospitalized for acute stroke, resulting in greater utilization of hospital resources
in addition to patient discomfort. Although post-stroke infections (PSIs) are commonly
referenced for interference with stroke recovery as well as associations with worse
clinical outcome, factors associated specifically with UTI after stroke remain unclear.
Aim
To provide a comprehensive narrative synthesis covering literature published with
results specific to the topic of UTI in stroke patients.
Methods
Literature review was performed searching the keywords “stroke” and “urinary tract
infection” in Pubmed. All manuscripts published in English were appraised for information
relevant to UTI in stroke patients. Applicable content was obtained, synthesized,
and summarized.
Results
Post-stroke UTI is found to be associated with prolongation of hospital length of
stay (LOS), discharge to a Care Home, and increased medical care costs. This process
possibly reflects the consequences of greater stroke severity and clinical courses
requiring urinary catheterization in hospitalized patients. However, UTI does not
share an independent association with long-term clinical outcomes including morbidities
and mortality.
Conclusions
A narrative review was performed, including the following topics: classifications
and epidemiology, pathogenesis, clinical features, and future directions. The heterogeneous
nature of reports on UTI in stroke patients remains as a major limitation in literature.
