Perioperative Mortality

An interesting report on perioperative mortality in NZ. It’s great that we have such transparency of data.

The mortality rates within 30 days of an operation are:

  • Coronary artery bypass graft 2.47%
  • Percutaneous transluminal coronary angioplasty 1.66%
  • Hip arthroplasty 1.58%
  • Cholecystectomy 0.37%
  • Knee arthroplasty 0.17%
  • General anaesthesia 0.12%
  • Bariatric surgery 0.07%

There is a huge difference based on you ASA score. The ASA scores are:

  1. Healthy person 0.05%
  2. Mild systemic disease 0.05%
  3. Severe systemic disease
  4. Severe systemic disease that is a constant threat to life 16.9%
  5. A moribund person not expected to survive without the operation 52.8%
  6. A brain-dead person
