The number of discharges (complications during the surgical admission, readmissions into the same hospital, readmissions into different hospitals) in which a surgical item or device fragment was retained during the procedure.

Discharges (NUM1 + NUM2 + NUM3) among cases defined in the denominator with ICD code for foreign body left in during procedure in a secondary diagnosis field during the surgical admission (see ICD codes). • NUM1: complications during the surgical admissions • NUM2: readmissions into the same hospital • NUM3: readmissions into different hospitals

All patients aged 15 and older with any surgical and medical discharges (including PDX and short LOS).

From NUM1 only: • PDX - with ICD- code for foreign body left in during procedure in a) the principal diagnosis field or b) secondary diagnosis present on admission (if known). • LOS - with a length of stay less than 24 hours where patient is discharged alive (in those countries where a timestamp of admission or discharge is not available, cases with a length of stay of 0 days shall be excluded). From NUM2 and NUM3: • Admission occurs more than 30 days after a previous one (matched record is not readmission)
