Panel 1
Mrs Campbell, 86, has delirium. An earlier urine culture grows bacteria.
Daughter: Does that mean this is a urine infection?
Panel 2
Assessment finds no urinary symptoms, fever or circulatory instability.
Doctor Ali: The culture does not establish a urinary infection by itself.
Panel 3
The doctor examines her and looks for other causes.
Nurse Brown: She has been drinking very little and has painful arthritis.
Panel 4
Dehydration and pain are treated. Her medicines are reviewed.
Doctor Ali: We will check how she responds to this care.
Panel 5
Antibiotics are not started for the culture result alone.
Doctor Ali: We are monitoring her closely for signs of infection.
Panel 6
That evening she remains confused, though more comfortable.
Mrs Campbell: Am I staying here tonight?
Panel 7
Staff repeat observations and assess new symptoms.
Nurse Brown: Please tell us about any new pain or feeling unwell.
Panel 8
The plan includes prompt reassessment if her condition worsens.
Doctor Ali: New infection signs would change our assessment and treatment.
Panel 9
Next morning she drinks more. Delirium assessment and care continue.
Daughter: She follows me better, but still loses track.
Commentary
Finding bacteria in urine does not by itself confirm a symptomatic urinary infection. In a clinically stable older person without urinary symptoms or signs of systemic infection, assess other possible causes of delirium and observe carefully.
