Priority Use Cases

The four highest mean scores were immunocompromised adults, children with fever without a focus and amber or red flag signs, febrile infants aged 1-3 months, and febrile neutropenic children. In adult use cases, immunocompromised adults and adults with fever without a focus ranked similarly and significantly higher than other adult use cases. In paediatric use cases, fever without a focus, febrile infants aged 1-3 months, and febrile neutropenia ranked similarly and higher than other paediatric use cases. All 19 proposed use cases were considered at least moderately important, though some were clearly prioritised. Unwell older neonates aged 3-28 days ranked slightly above neonates under 3 days old, but this difference was not statistically significant. The highest-priority use cases involved vulnerable patients and clinically uncertain presentations.
