## TL;DR

A cancer patient with a fever or severe sickness during treatment should be seen quickly by a team that knows chemotherapy, not wait hours in a general emergency room.

## Summary

Cancer patients present to emergency departments frequently during treatment and are often admitted when same-day specialist assessment would have avoided it. Acute oncology services and dedicated assessment units (established across the UK and in some US centres) provide a direct line, rapid triage, and protocolised management for neutropenic fever, dehydration, and immune-related toxicity. The proposal is to make such a unit a required component of every treating centre.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: Centres with an acute oncology assessment unit will reduce emergency-department attendances by treated patients by at least 30% and reduce admissions for low-risk febrile neutropenia by half.
- Rationale: Direct access to specialist assessment avoids the delays and defaults of general emergency medicine, where admission is the safe reflex for unfamiliar toxicities.
- Proposed test: A before-and-after evaluation with emergency attendances, admissions, length of stay, and time-to-antibiotic for febrile neutropenia as endpoints.
- Maturity: being-tested-at-scale
- Actor: clinic
