Pandemic Influenza Triage Tools

Welcome to the Pandemic Influenza Triage Tools!

Use the tabs above or the buttons below to explore these triage tools. We hope you will find these tools useful when planning for or responding to an event.


The Pandemic Influenza Triage Tools are a toolkit for healthcare professionals and community healthcare leaders and decision makers to manage influenza-like illness (ILI) and medical surge during a pandemic. The toolkit consists of these tools:

Pandemic Influenza Triage Algorithm (PITA): A standardized tool for use by all community healthcare professionals for face-to-face encounters to triage ILI patients.

Community Healthcare Decision Making Tool (CHDMT): A tool for use by community healthcare leaders and decision makers to assess medical surge at the community level to mobilize necessary resources during an influenza pandemic, and assist in ensuring patients are directed to appropriate sites of care. The CHDMT consists of the following components:

  • Community Site-of-Care Tool: A tool to determine the appropriate site of care for ILI patients based on assigned PITA levels.
  • Community Healthcare Decision Pathway: Resource and medical surge assessment tool to assist in determining appropriate site of care in treating patients with assigned PITA levels.

These triage tools collectively provide a timely and accurate patient and resource assessment that will help reduce medical surge during an influenza pandemic.

The Healthcare Preparedness Activity (HPA) within CDC’s Division of State and Local Readiness (DSLR) works to improve the healthcare delivery system’s ability to respond to potential natural disasters and public health threats, such as pandemic influenza.
