Brief Summary

Delirium is an acute confusional state that is experienced by many older adults who are admitted to hospital. To treat delirium the underlying cause needs to be identified promptly, but this is challenging. One of the potential causes of delirium is infection. Urine tests show that most patients experiencing delirium have bacteria in their urine, however, bacteria in the urine is common among older adults, and does not automatically indicate an infection is present. As a result it is difficult to know whether a lower urinary tract infection is present as individuals with delirium are frequently unable to report clinical signs of infection - symptoms of pain or discomfort with urination, having to urinate more frequently or pelvic discomfort. Very often, individuals with delirium are treated with antibiotics despite the fact that it is unknown whether antibiotics help to improve delirium in cases where bacteria in the urine is present. This proposed study is a randomized controlled trial that will examine if adults (age 60 or older) with delirium and suspected infection benefit from taking antibiotics.

Primary Outcome Measures
NameTimeMethod
Delirium at day 7 or at day of hospital discharge, whichever is earliestDelirium will be assessed at the first of day 7 or discharge

Delirium will be assessed using Confusion Assessment Method (CAM). CAM assesses 4 delirium features: \[1\] inattention, \[2\] acute and fluctuating level of consciousness, \[3\] disorganized thinking and \[4\] altered mental status. For a diagnosis of delirium by CAM, the patient must display feature \[1\] AND \[2\], AND EITHER \[3\] or \[4\].

Secondary Outcome Measures
NameTimeMethod
Length of hospitalizationUp to 30 days
Number of participants with bacteremia (bacteria isolated in blood culture)Up to 7 days
Number of participants who were transferred to Intensive Care Unit (ICU)Up to 7 days
Number of participants who had a fallUp to 7 days
Number of participants who received antipsychoticsUp to 7 days
Number of participants with C. difficile infectionBy 30 days

C. difficile will be defined as a combination of a positive microbiological test for C. difficile (if still hospitalized at the time of diagnosis), or self-reported diagnosis of C. difficile (provided the patient reported diarrhea and receipt of an antibiotic to treat C. difficile)

Number of participants who diedBy 365 days
Number of participants who were readmitted to hospitalBy 30 days
Number of participants who were physically restrainedUp to 7 days
Days of antibioticsUp to 7 days
