Eisie Truter delivered the presentation at the 2014 Operating Theatre Management Conference.

Focusing on strategies for implementing the National Safety and Quality Health Service Standards and the importance of communication to improve patient safety and clinical practice, the 2014 Operating Theatre Management Conference brought together operating room management and perioperative professionals to review current initiatives across the country.

Eisie Truter - Waiariki Institute of Technology - Infection Control in the OR: Just How Important Is It?

  1. 1. Infection Control in the OR: Just how important is it? Elsie Truter Waiariki Institute of Technology Rotorua New Zealand
  2. 2. Challenges in the OR Preventing Surgical Site Infections against a backdrop of; Changes to perioperative nursing practice and surgical techniques New equipment – is it safe to use? How do we sterilise or disinfect? New infectious diseases Antibiotic Resistance Staff compliance with Infection Prevention and Control practice
  3. 3. Government Initiatives • Health Quality and Safety Commission New Zealand • Current Infection Prevention and Control Foci; • Hand Hygiene • CLAB prevention • Surgical Site Infection • To come – Antibiotic Stewardship
  4. 4. Government Initiatives • Australian Commission on Safety and Quality in Health Care • Australian College of Operating Room Nurses (ACORN) 2014-2015 Standards for Perioperative Nursing • The common emphasis (from an IPC perspective) is the reduction of Health Care Acquired Infections
  5. 5. This presentation • Will look at; • Antibiotic resistance • Pre surgical skin preparation – showering with or using Chlorhexidine impregnated cloths. • The behaviour of the multidisciplinary team in the OR
  6. 6. A (very) Brief History
  7. 7. Van Leeuwenhoek 1673
  8. 8. Semmelweis 1847
  9. 9. Louis Pasteur Lister
  10. 10. Anaesthesia 1847 Sir James Simpson
  11. 11. Surgical site infections
  12. 12. Bacterial resistance
  13. 13. Antibiotic overuse Estimated Annual Human Antibiotic Use (USA) Site Amount Correct use Hospital 190 million defined 25 - 55(%) daily doses/year Community 140 million courses/year 20- 50(%)
  14. 14. Complacency with aseptic technique infection
  15. 15. Global microbial resistance (WHO Global Report 2014) • Prevention of the spread and control of Multi drug – resistant organisms (MDRO’s) at a critical level. • Availability of antibiotics to treat these infections extremely limited • Worldwide the most common MDRO’s are;
  16. 16. MDRO’s • MRSA - Methicillin resistant Staphylococcus aureus • ( prevalence 10% in Auckland NZ) • VRE – Vancomycin resistant Enterococci ( rare in NZ) • ESBL- Extended Spectrum b lactamase Gram –ve organisms ( increasing in NZ 157/100000) • CRE – Carbapenem resistant Enterobacteriaceae • MRAB - multi resistant Acinetobacter baumannii
  17. 17. MDRO’s • Understanding the current resistance pattern influences both prophylactic and therapeutic a antibiotic use
  18. 18. Antibiotic Stewardship in the OR • Key to reducing MRDO’s and Healthcare associated infections • Therapeutic antibiotics- give narrow spectrum for the shortest period of time, for 24hrs after incision only. Cardiac surgery for 48 hrs only. • Prophylactic antibiotics – within 1hr prior to skin incision. Superior efficacy between 0-30 min prior • ( Anderson, et.al., 2014)
  19. 19. • Exception: • Vancomycin and fluroquinolones must be administered 2 hrs before incision
  20. 20. Antibiotic stewardship in the OR • ACORN - IPC Standard 11 - recommends; 2g Cephazolin for all patients up to 80kg • 3g for pts over 120kg. Paediatric dose 30 mg/kg • Experts believe prophylactic antibiotics should be administered prior to tourniquet inflation. • Redose prophylactic antibiotics for long procedures or excessive blood loss ( Anderson, et.al., 2014)
  21. 21. Antimicrobial-Resistant Pathogen Antimicrobial Resistance Antimicrobial Use Infection Prevent Transmission Prevent Infection Optimize Use Effective Diagnosis & Treatment Susceptible Pathogen Antimicrobial Resistance: Key Prevention Strategies
  22. 22. Preventing Infection CDC estimates that 5% of all patients acquire an infection leading to 100.000 deaths per annum (CDC, 2010) Where do these pathogenic microbes come from? Most come from endogenous microbes – skin, intestines
  23. 23. Within hours of admission the room will reflect the patient’s microbiome . These microbes will move to adjacent patients and rooms. Visitors add to this mix. (Arnold,2014)
  24. 24. Preventing Infection • Patients become colonised with hospital microbes within hours – they could be resistant strains. • These can lead to infection once natural defence barriers have been broken
  25. 25. Entry Points
  26. 26. ______________________________________________________________________ Clinical infections Colonised patients
  27. 27. Preventing Infection: Minimising skin flora • Using Chlorhexidine Gluconate (CHG)2-4% wipes or showering with CHG has been shown to reduce surgical site infections from 3.19% - 1.59% ( Eiselt,2009) • Considered an adjunct risk reduction strategy to pre-operative skin prep with Chlorhexidine and alcohol or povidone-iodine and alcohol • Broad spectrum (Gram –ve and Gram +ve bacteria) killing effect
  28. 28. Preventing infection Minimising skin flora • Higher concentrations of Chlorhexidine gluconate are rapidly bactericidal • Does not denature in the presence of serum and blood and has a longer residual effect • BUT cannot be used on periorbital sites – eyes and ears. Use of Povidone-iodine recommended • Patient compliance difficult to assess.

Those n.d were given a count of 5 for analysis • Postwash values for ‘three washes’ is after one wash. Mean counts remained below 10 after all three washes.
  30. 30. Chlorhexidine Gluconate 4% pre-op washes. 2 cohorts 10/arm
  31. 31. Preventing Infection: Pre-screening • May be logistically complicated and is expensive • Decide between vertical or horizontal surveillance • Consensus seems to be that riskier patients with complex surgery and co morbidities should be screened. • Each institution to set realistic policies • ( Making Health Care Safer ll , 2013)
  32. 32. HAIs are SSI ( previously called SWI)Exogenous Sources of Infection
  33. 33. To mask or not to mask?
  34. 34. ACORN Infection Prevention Standard Statement 6 • Wear a mask; • where a sterile field is being prepared or used • to protect the health care worker against blood and body fluid spatters • To decrease the dispersals of microbial droplets from nose and mouth
  35. 35. ACORN Perioperative Attire • Shall replace all outer garments and shall be worn correctly at all times when entering the operating suite • Do not wear perioperative attire outside the healthcare facility
  36. 36. ACORN Infection Prevention Standard Statement 4 • The multi disciplinarary team shall comply with infection control parameters related to the environmental boundaries of the perioperative setting i.e. zone conformity
  37. 37. Other Exogenous Sources • Environment - air changes, temperature and humidity • Inadequately cleaned environment
  38. 38. In conclusion: Infection prevention in the OR is paramount • This presentation has highlighted a few important infection prevention methods in the OR 1. Antibiotic stewardship 2. The use of preoperative showering to decrease skin colonisation 3. The behaviour of the multidisciplinary team in the OR
