Work out infection rate per 1000 days instantly with clear inputs, formula shown and shareable results.
Divides infections by device or patient days and multiplies by 1000, the standard device-associated infection rate used in surveillance reporting.
Device-associated rate
Rate per 1000 device days = infections / device days x 1000
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
It adjusts for exposure time, so units with longer device use are compared fairly.
Each calendar day on which a patient has the device in place, counted once per patient per day.
