Area of Science:

  • Medical research
  • Health economics
  • Infectious disease

Background:

  • Poststernotomy mediastinitis (PSM) is a serious complication following cardiac surgery.
  • Staphylococcus aureus is a common pathogen causing PSM.

Purpose of the Study:

  • To quantify the additional hospital costs associated with Staphylococcus aureus poststernotomy mediastinitis (PSM).

Main Methods:

  • Retrospective case-control study matching nine S. aureus PSM cases with nine controls.
  • Data on length and cost of hospital stay were extracted from a clinical costing system.

Main Results:

  • S. aureus PSM cases had a significantly longer hospital stay (42.6 days vs. 10.4 days).
  • The mean excess cost per patient due to S. aureus PSM was NZ$45,677.

Conclusions:

  • Deep surgical site infections like S. aureus PSM impose significant financial burdens.
  • Strategies to prevent S. aureus PSM can yield considerable cost savings.
