The number of hip and knee replacement discharges (complications during the surgical admission, readmissions into the same hospital, readmissions into different hospitals) with postoperative deep vein thrombosis.

Discharges (NUM1 + NUM2 + NUM3) among cases defined in the denominator with ICD code for deep vein thrombosis in a secondary diagnosis field during the surgical admission (see ICD codes and in any diagnosis field during readmissions within 30 days of the surgery. If the date of surgery is not available, then 30 days from the admission date for the first surgical admission. • NUM1: complications during the surgical admissions • NUM2: readmissions into the same hospital • NUM3: readmissions into different hospitals

Hip and knee replacement discharges, meeting the inclusion and exclusion rules with an ICD code for an operating room procedure.

• Obstetric hospitalisations - Cases assigned to an obstetric DRG, e.g. from MDC 14 or specified pregnancy, childbirth, and puerperium codes in any field. • IVC - cases from the numerator and denominator where a procedure for interruption of vena cava or insertion of inferior vena cava filter occurs before or on the same day as the first / main operating room procedure (hip/knee replacement and all surgical discharges). • PE - if a patient has both PE and DVT, such case is assigned to PE. • From NUM1 only: - PDX - cases with principal diagnosis or secondary diagnosis present on admission (if known) of deep vein thrombosis during the surgical admission (NUM1). - LOS - surgical admissions (NUM1) with length of stay less than 2 days. • NUM 2 and NUM3 - READM - readmissions more than 30 days after the operation date from the numerator (matched record is not considered readmission as cases are considered to be at risk within 30 days).
