Sepsis for paramedics: a case breakdown of the 'just a UTI' call that wasn't

Is there a call type that looks more routine than "elderly female, weak, possible UTI"? That routineness is the classic sepsis paramedic trap. The illness is time-sensitive, but the call rarely sounds urgent. This case breakdown is a composite, built for teaching rather than drawn from a single real patient, and it shows where the decision points sit.

#The call

A daughter calls because her 81-year-old mother "isn't herself." She has been off for a day: tired, eating less, a bit muddled. She had burning on urination earlier in the week and was waiting for a doctor's appointment.

On arrival she is sitting in her armchair, pleasant and slightly confused about the day. She says she feels "fine, just tired." Her skin is warm. The daughter says the confusion is new.

It would be easy to frame this as a low-acuity transport for a urinary infection. The crew does not.

#Decision point one: the sepsis paramedic question

Sepsis is a dysregulated response to infection that causes organ dysfunction. In practical field terms, that means two questions:

1. Is there a likely infection? Here, yes: recent urinary symptoms, warm skin.
2. Is there evidence the body is not coping? New confusion is organ dysfunction until proven otherwise.

Clues that should push a paramedic toward suspecting sepsis include:

• New or worsening confusion, especially in older adults
• Fast breathing, which is often the earliest and most overlooked sign
• Fast heart rate
• Low or falling blood pressure
• Mottled, cool or delayed-refill skin, or reduced urine output
• A temperature that is high, low or, importantly, normal; fever is not required

Older adults, people on immunosuppressants and people with chronic illness often present with blunted signs. A normal temperature does not lower your suspicion.

#Screening, pre-alert and fluids

Once sepsis is on the table, three decisions follow quickly.

#Decision point two: screen with your service's tool

The crew obtains a full set of vital signs. Her respiratory rate is elevated, her heart rate is up and her blood pressure is lower than her daughter says is normal for her. Her glucose is within normal limits.

Many Canadian services use a structured prehospital sepsis screen built around suspected infection plus abnormal vital signs or mental status, with some adding other measures if they are within scope. Whatever tool your service uses, the principles are the same:

• Apply it every time you suspect infection, not only when the patient looks unwell.
• Use the actual numbers. Count the respiratory rate for a full interval. Estimates tend to be normal.
• A negative screen is not a clean bill of health. If your gestalt says sick, document why and escalate anyway.
• Compare with baseline. "Normal for her" matters, so ask family or check records.

In this case the screen is positive.

#Decision point three: pre-alert and choose the pace

Sepsis care in hospital is time-dependent. Early recognition lets the emergency department prepare for cultures, blood work and antimicrobials without the delay of a standard triage queue.

A good sepsis pre-alert is short and specific:

• Age and suspected source
• Which screen criteria were met
• Mental status compared with baseline
• Most recent vital signs and the trend
• Any treatment given and the response

The crew pre-alerts, notes the time and moves with purpose. The scene time stays short because nothing on scene will fix the underlying problem.

#Decision point four: fluids per directive, with reassessment

Her blood pressure stays soft and her skin is cool at the extremities. The crew reviews the sepsis or hypotension medical directive for their service. Many directives allow fluid boluses for adult patients with signs of hypoperfusion, with specific indications, contraindications and reassessment requirements.

General principles that hold regardless of the exact directive:

• Check the contraindications. Heart failure, kidney disease and signs of fluid overload all change the picture.
• Reassess after each bolus. Lung sounds, work of breathing, mental status and blood pressure.
• Stop if harm appears. New crackles or increasing breathlessness mean it is time to stop and report.
• Do not let a line delay transport. Fluids can be started en route.

Doses and volumes come from your directives, not from this article.

#Documentation and handover

The crew's chart matters as much as the pre-alert. A receiving team reading it later should be able to see when infection was suspected, which screen criteria were met, what the baseline was according to family and how the patient responded to each intervention. Recording the daughter's description of the new confusion, in her words, gives the hospital a baseline it cannot measure for itself. Clear timing also lets your service review its own sepsis care later, which is how systems improve.

#What happened next

On arrival she is taken straight to a resuscitation bay because the team was expecting her. Her handover leads with the screen result, the new confusion and her response to fluids. The emergency department continues sepsis care from where the crew left off.

The crew's best decision was not a procedure. It was refusing to treat "just a UTI" as a low-acuity label.

#For training leads

Sepsis calls fail quietly, so training should target the quiet failures:

• Build mundane scenarios. Weakness, falls, "not herself." Make the sepsis cue subtle.
• Grade respiratory-rate counting. It is the vital sign most often estimated and most often missed.
• Practise the pre-alert. Have crews deliver it in a set format and time it.
• Include fluid-response reassessment. Add a patient who develops crackles so crews practise stopping.

Short, repeated scenarios, including decision-training on platforms like Imedica, help crews practise spotting a sepsis pattern hidden inside an ordinary-sounding call.

#The takeaway

Sepsis in the field is a pattern, not a single sign. Suspect infection, ask whether the body is coping, screen with your service's tool, pre-alert early, give fluids only as your directives allow and reassess. The call that sounds routine is often the one that needs you most.
