The National Healthcare Safety Network (NHSN) is the system through which
US healthcare facilities report infections and safety data — the source of the
national figures on bloodstream infections, surgical site infections, *C.
difficile* and the rest.

A surveillance system used by thousands of separate institutions only produces
comparable numbers if every institution changes what it does at the same
moment and in the same way. **The quarterly NHSN newsletter is how that
happens.**

What a quarter's edition contains

Across recent editions, the recurring sections are:

  • Analysis and protocol changes — the definitions and methods, which is
    the part that alters what a reported number means
  • Antibiotic Use and Resistance (AUR) Module updates and enhancements
  • Healthcare Personnel Safety Component highlights
  • Long-term Care Facility Component highlights
  • Dialysis Component updates, including quality improvement programme
    deadlines
  • Biovigilance / Hemovigilance reminders
  • Education and training information, and general NHSN news

Individual quarters carry specific consequences: one edition announced the
retirement of the CLIP Modules, another a **Q1 dialysis quality
improvement programme deadline**.

Why a newsletter rather than a manual

A protocol change published in a manual is authoritative and easy to miss. The
newsletter exists because the failure mode of a distributed surveillance
system is not disagreement but drift — facilities carrying on with last
year's definitions while the national analysis assumes this year's.

Every quarterly edition is, in effect, a synchronisation point for the data
that the national healthcare-associated infection reports are built from.

Facilities can subscribe by email to receive it.
