Approach to fever by age and immune status — OSCE

Station brief (candidate)

• Explain why age drives the work-up threshold in febrile infants.
• Outline the assessment: threat gate first, then age-banded risk stratification.
• State which investigations a 5-week-old fever without source requires and why.
• Agree a plan that respects parental concern and gives a specific safety-net.
• Avoid reassuring on temperature alone or promising discharge before assessment. ^{[1] [2] [6]}
