Introduction: Surgical site infections (SSI) are related to a surgical procedure and
affect the surgical wound or deeper tissues. In orthopaedic and trauma surgery there
is a great variability of procedures with influence in each evolution. The aim of this
study is to fix SSI incidence in relation of surgical procedure.MethodsThis report
contains data of 19.948 procedures collected from 1996 to 2008 at a Specialist
Orthopaedic Hospital. The SSI surveillance is focused on categories of surgical
procedure (Hip arthroplasty, Knee arthroplasty, Spine surgery and Hip fracture) with
each category containing a defined set of similar procedures. A basic of demographic
data and details about operation itself are collected for each procedure. Patients are
followed up throughout their hospital stay and after hospital discharge. We present
the incidence of SSI by risk group and surgical procedure. SSI are categorized in
type, moment of diagnosis, micro-organisms reported. Results: Rates of SSI are
highest in hip hemiarthroplasty after fracture and in hip and knee revision
procedures. Rates of SSI increase with the number of risk factors present in the
patient, especially after fracture procedures. The most common infecting microorganism
was coagulase-negative staphylococcus, followed by Staphylococcus
aureus, enterococci and streptococci. 38% of the infections arise after one year of
surveillance. Conclusions: Our results confirm difference in rates of SSI depending of
surgical procedure in orthopaedic and trauma surgery. We believe that our decision
to monitor infection with a long term follow up it’s the better way to avoid underreporting
of infection.
