Riya reached a diagnosis but missed safety-critical signal — the errors below trace back to unpinned red flags and context.

Why these went wrong

Each error traced back to the pin decisions that caused it

Safety

Omitted Acute coronary syndrome — a can't-miss diagnosis

BecauseNever pinned “Heart Rate” and “Systolic Blood Pressure”, so nothing prompted the dangerous-alternative sweep for this presentation.

Heart Rate· Safety red flagSystolic Blood Pressure· Context factor

Treat Acute coronary syndrome as a must-exclude for this presentation — pin the context that makes it possible, then rule it in or out explicitly.

Safety

Omitted Aortic dissection — a can't-miss diagnosis

BecauseNever pinned “Heart Rate” and “Systolic Blood Pressure”, so nothing prompted the dangerous-alternative sweep for this presentation.

Treat Aortic dissection as a must-exclude for this presentation — pin the context that makes it possible, then rule it in or out explicitly.

Safety

Advanced to the workup with red flags unflagged

BecauseDid not pin “Heart Rate” and “Respiratory Rate” as safety red flags before ordering, so stabilisation was not prioritised over diagnosis.

Flag the red flags first and stabilise before pursuing the diagnostic workup.

Diagnosis

Ranked Community-acquired pneumonia above Pulmonary embolism

BecauseNever pinned “Systolic Blood Pressure” and “Clear chest on auscultation” — so the pre-test probability for Pulmonary embolism stayed low and a mimic outranked it.

Pin the discriminating findings before committing the differential — they raise the pre-test probability that puts Pulmonary embolism on top.
