Answer

Because acute stroke patients are entering rehabilitation programs earlier than ever before, it is important to understand the impact of urinary tract infections on this specific population. Patients with a diagnosis of acute stroke are more than twice as likely to develop urinary tract infections as other hospitalized patients, regardless of the use of urinary catheters. [51]

Urinary tract infections in poststroke patients also independently predict poor outcomes, including death, prolonged hospitalization, and poorer neurological outcomes. [52] Acute stroke patients with hospital-acquired symptomatic urinary tract infections are less likely to be discharged home. [53] Additionally, acute stroke patients with symptomatic urinary tract infections are more likely to perform at a lower functional level while participating in an acute inpatient rehabilitation program.

A Cochrane summary completed in 2013 found some evidence, albeit limited, for the benefit of prophylactic antibiotics in nonsurgical patients who undergo bladder drainage. [54] More research is clearly needed to evaluate the potential benefit to stroke patients with urinary incontinence and/or neurogenic retention in the acute and postacute setting.
