1. Aseptic Technique

• Principles were developed to reduce the risk of
  wound contamination.

8
Defining the Risk of SSI

• Risk of SSI Dose of Bacterial
• Contamination X Virulence
• Resistance of Host (patient)
• Berry Kohns, Operating Room Technique, 11th
  ed., p. 254

9
Causes of Wound Contamination

• Exogenous sources
• Cleanliness of environment, lack of proper
  airflow, shedding by the Surgical Team
• Endogenous sources
• Patients own skin/hair
• Infection at a remote site

10
The Number One Source

• People Shedding
• 4000-10,000 particles per minute
• (Berry Kohns, Operating Room Technique, 11th
  ed., p. 252)
• Carried by wind currents to the sterile field
  which results in wound contamination.
• Patient
• Surgical Team
• Ancillary Personnel
• Sales Reps
• Students
• Passersby

11
Shedding

• Carried by Wind Currents (TRAFFIC)
• Traffic Patterns
• Amount of Traffic
• Sherertz, et al. Cloud HCWs. Emerging Infect
  Dis. 20017(2) 241-44.
• Edmiston, et al. Airborne Particulates in the OR
  Environment. AORN 1999 69(6) 1169-1183.

12
2. Traffic Control

• Essential personnel only
• One foot (min) perimeter around sterile field
• Sterile fields should be a destination, not a
  thoroughfare
• Limit students and observers
• The right of the student to learn vs. the right
  of the patient to receive safe patient care
• Utilize alternative methods of communication

14
Containment is the key

• 1. Patient
• Pre-op Showers
• Hat and clean gown/linen for patient
• 2. Surgical Team
• Hand Hygiene
• Nocardia farcinica (Wenger, et al. J Infect Dis.
  Nov 1998)
• Proper aseptic technique
• Properly worn hats, masks, clean OR scrubs,
  jackets, minimal jewelry (AORN scrub attire)

15
Ban Skull Caps

• Dineen, P, Drusin, L. Epidemics of Postoperative
  Wound Infections Associated with Hair Carriers.
  Lancet 1973 (Nov) 1157-59.

16
Lack of Containment

• BAD

• VERY BAD

17
Standards of Excellence

• PETA APPROVED

• GOLD STANDARD

18
Environment

• Room Requirements
• Ventilation System (15/hr 3 fresh)
• Positive pressure
• Temperature (68-73 F)
• Humidity (30-60)
• Room Cleaning
• Between cases
• Terminal cleaning
• Types of construction materials
• Clutter
• AORN, Recommended Practices for Perioperative
  Nursing Safe Environment of Care. (2008 ed., p
  357)

19
Surgical Conscience

• Requires strict adherence to the principles of
  aseptic technique by all team members for every
  patient on every case.
• ORs that value these principles create a patient
  centered culture.
• Girard, NJ. Surgical Conscience Still
  Pertinent. AORN (2007)86 (1) 13-14.

20
3. Sterilization

• Proper management of Sterile Processing
  Departments
• Proper sterilization techniques

21
Partnering with Sterile Processing

• SPD processes can have an impact on SSIs
• Association for the Advancement of Medical
  Instrumentation (AAMI) guidelines
• Staff should
• Obtain certification
• Assess all sterilizers daily
• The Joint Commission will be focusing on this
  area.

22
Flash Sterilization

• Utilized for
• Dropped instruments
• Poorly designed work processes
• Lack of instrumentation
• Surgeon scheduling
• Results in contamination due to
• Poor cleaning due to lack of time
• Methods of delivery to the sterile field
• Closed containers are best practice
• TJC will be looking for them
• Carlo, A. The New Era of Flash Sterilization.
  AORN 2007 86(1) p 58-70.

23
Flash Data

• Calculation of flash events rate x
  100 of cases/month

24
4. Antibiotic Prophylaxis

• SCIP Measures
• INF 1,2,3
• Goal gt90
• Best Practice- Anesthesiologists
• Proper dosage for obese population (BMIgt30)
• Dont forget redosing q 3 hours

25
5. Hair Removal

• SCIP INF 6 Surgery patients with appropriate
  hair removal.
• Minimize as much as possible
• Clippers only
• Not in the OR!

26
6. Skin Antisepsis

• The attributes of an appropriate surgical skin
  antiseptic require
• The ability to significantly reduce
  microorganisms (2 log, 3 log)
• Provide broad spectrum activity
• Be fast acting
• Have a persistent effect
• All products with FDA approval meet this criteria
• AORN, Recommended Practices for Perioperative
  Nursing Skin Antisepsis. (2008 ed., pp537-555)

27
Other Skin Antisepsis Considerations

• Procedure
• Prep area
• Application Methodology
• Scrubbing vs. Painting
• Length of the procedure
• Challenges to the prep area
• -blood, saline, friction
• Patient Safety

28
Critical Thinking

• Ultimately, the OR nurse decides at the point of
  care by assessing the patient to insure that the
  skin antisepsis planned for will be appropriate
  for that patient based on allergy status, body
  site, and skin integrity.

29
Current Recommendations

• CDC SSI guideline states to use an appropriate
  antiseptic
• SHEA Compendium - Optimal preparation and
  disinfection of the operative site
• AORN compares products but does not provide
  specific product recommendations

30
Current Research

• Limited research is available that compares
  commonly used skin antiseptic agents with SSI
  outcomes
• The majority of the literature compares microbial
  counts
• The U of VA study compares SSI outcomes

31
Preoperative skin preparation on postoperative
wound infection a prospective study of three
skin preparation protocols

• Compared 3 methods
• Iodophor Scrub/ETOH/Paint vs. ChloraPrep vs.
  Duraprep
• Sample size 3209 patients
• Conclusions
• A statistical difference with a
• lower SSI trend using iodine based products.
• Swenson, et al. Infect Control Hosp Epidemiol
  2009 30964-971

32
Product Application

• Prewash prior to application
• Follow manufacturers directions
• Utilize proper aseptic technique during
  application gloves to contain shedding

33
7. Dressings

• Optimal dressings are
• Permeable to gas exchange
• Impermeable to microbes/contamination
• Create a moist healing environment (37C)

34
Dressings

• Stay in place
• Good adherence properties
• Change on day 2-3 unless drainage, dirty, or
  damaged
• Use proper aseptic technique when applying the
  dressings before the drapes are removed
• Partner with Wound Care Specialists
• Sussman, C, Bates-Jensen, B. Wound Care A
  Collaborative Practice Manual for Health
  Professionals 2006 (Chap11)

35
The New Basics

• Glycemic Control
• Nasal Decolonization

36
Glycemic Control

• 30-35 of cardiac patients are diabetics
• SCIP INF 4 Cardiac surgery patients with
  controlled 6 a.m. postoperative serum glucose.
• The OR cannot be a black hole

37
S. aureus Nasal Carriage

• Between 25-30 of all patients are colonized
• Another 60 carry it intermittently
• 85 of S. aureus infections were endogenous in
  SSI study populations
• Nasal decolonization should be considered due to
  the risk of S. aureus SSIs
• Van Rijen, et al. Intranasal Mupirocin for
  reduction of S. aureus in surgical patients with
  nasal carriage. J Anti Chemotherapy 2008
  61254-261.

  Postoperative Staphylococcus Aureus Infections.

• Standardize
• Use forms to quantify when possible
• Simplify- pick one thing to get started

44
Process Improvements
