Healthcare–associated Infection (HAI) and Present on Admission Infection (POA) Worksheet Generator

Welcome to the NHSN Healthcare–associated Infection (HAI) and Present on Admission Infection (POA) Worksheet Generator Version 1.0. The Generator operates based upon the currently posted guidance found in the Patient Safety Component Manual, Chapter 2, Identifying Healthcare-associated Infections (HAIs) in NHSN [PDF – 1M].

The Worksheet Generator is a web-based tool that is designed to identify the:

• 7-day Infection Window Period
• Date of Event and POA or HAI determination
• 14-day Repeat Infection Timeframe (RIT)
• Secondary Bloodstream Infection Attribution Period (if applicable)

This Worksheet Generator does not determine that all NHSN infection criteria have been met. It is incumbent upon the user to determine that the infection criterion was met as reflected in the dates and information supplied.

Please note that the Worksheet Generator will not ask you to enter any patient identifiers. The Worksheet Generator does not store any data that you enter, and it will not report any data that you enter or any determinations to the NHSN. You will not be able to export data entered into the Worksheet Generator but you will be able to print the worksheet.

Use the VAE calculator and MDRO & CDI LabID Event calculator when conducting VAE or MDRO/LabID event surveillance. Also note, the Worksheet Generator is not for use when conducting SSI surveillance or when making determinations for meeting the ENDO definition.
