Surgical Site Infection Improvement Programme: National Orthopaedic Surgery Report July–September 2016

3 Apr 2017 | Infection Prevention & Control

This report presents the results of the SSII Programme for the period 1 July to 30 September 2016. It also provides cumulative data from 1 March 2013 to 30 September 2016.

Please contact us if you would like to see reports prior to 2016–17.

During this surveillance period:

  • district health boards (DHBs) performed 2537 hip and knee arthroplasty procedures, compared with 2733 in April to June 2016
  • there were 30 surgical site infections (SSIs) in this quarter, a rate of 1.2 percent. Most of the SSIs, 21 (70 percent), were deep/organ space. Nine SSIs (30 percent) were superficial
  • DHB performance against the prophylaxis timing quality and safety marker (QSM) for primary procedures was 98 percent. The target is 100 percent. Eight DHBs achieved 100 percent compliance and 18 DHBs recorded greater than 95 percent. Five DHBs had one or more procedures where timing was not recorded. Fewer than one percent of cases had antibiotic prophylaxis given either early or late
  • DHB performance with the dose QSM was 96 percent. The target is 95 percent. Seventeen DHBs now comply with the dose QSM. The most common reason for missing the QSM is the use of 1 g doses of cefazolin, which were used most often at Taranaki DHB. Of the 33 patients who received 1 g of cefazolin, six (18 percent) were under-dosed as they weighed more than 80 kg
  • prophylaxis was stopped within 24 hours in 99 percent of primary procedures. Twelve DHBs stopped prophylaxis within 24 hours for all primary procedures. Canterbury DHB and Waitemata DHB gave more than 43 patients prophylaxis for longer than 24 hours for all procedures. Continuing antibiotic prophylaxis until drains or catheters are removed is of no known benefit to patients and can promote antibacterial resistance. There has been considerable improvement in prophylaxis practice since the start of the SSII Programme, when only 61 percent had prophylaxis stopped in under 24 hours
  • seven DHBs met both QSMs: Capital & Coast, Hawke’s Bay, Lakes, Nelson Marlborough, South Canterbury, Wairarapa and Whanganui. Congratulations to these DHBs.
