    Hi all

    Can I ask a question which may seem naive to those with a recent theatre background? When applying antiseptic solution as part of a surgical skin preparation prior to a procedure, is it best practice to apply two ‘coats’ of antiseptic solution, one immediately on top of the other, using different swabs?

    I can see not real benefit in doing this from an antiseptic action viewpoint (apart from mechanical friction) Can also not see this mentioned in a cursory review of any SSI prevention best practice guidelines.

    Any comments? Any references to get me up-to-date if I need to be updated?

    Thanks
    Michael

    Skin preparation research and product is rapidly evolving as is our understanding of it’s role and the additional benefit of daily CHG bathing. This topic was discussed and presented in great depth at APIC 2013 and on re-listening recently to recordings of APIC sessions I took home several messages including:

    1. AORN in their Standards use evidence to base preparation instructions;

    2. CDC is about to release a new SSI guideline which addresses this topic and much else

    3. Ultimately, clinicians need to follow manufacturers’ specific directions for their specific product

    In short I don’t think there is an evidence-based “one-stop” answer to your question.

    Interesting science published around this in the last 12 months in AJIC, ICHE and NEJM esp.

    Cheers

    Michael,

    Seems to add unnecessary expense to me.. even if the swabs are low cost.

    If skin prepping is done correctly the first time, I see no need to
    ‘double prep’, although I do know a clinician who does before placing a
    PICC.

    I do have a little literature (for VA), but it’s not as current as what
    you might be after.

    Dear Michael,

    There is not much literature or evidence available concerning this particular question, in terms of guiding you exactly how many coats or layers you should apply.

    However, some basic information can be derived from the physicochemical properties of antiseptics and of antiseptic action.

    Whether there are additional “coats” (in the sense of layers) on top of each other is of relatively little relevance.

    All microbial killing by disinfection and sterilisation (including antisepsis) is a time-dependent action. You can see that from “time-kill-curves” of microorganisms when exposed to these processes. Figures are, for example, in the Gardner & Peel textbook, which is an Australian reference. The time-dependent nature of microbial killing is the conceptual reason for having contact times with any antisepsis or disinfection process.

    Repeated applications of antiseptics for the purpose of skin antisepsis simply help to keep sufficient fresh antiseptic on the skin site in order for it to be antimicrobially effective for the duration of the contact time. It is a simple physical principle that if the site is not wet with the antiseptic (e.g. by evaporation), it cannot act.

    The Australian College of Surgeons (RACS) has an earlier guideline on infection prevention in surgery (not sure if this has been updated) that says “at least 2, but preferably 5 minutes” of contact time of the antiseptic for surgical skin prep.

    Clearly recognising that this is arbitrary, not guided by good evidence and up for debate, what I have recommended in the past is to have 3 repeated applications, providing an overall contact time, including evaporation at the end of the applications, of 5 minutes. The rationale for this recommendation is that this would be consistent with the RACS recommendation of 5 min (for major surgery you want to err on the side of greater caution) and consistent with the physicochemical properties.

    Best regards, Matthias.

    Michael,
    I believe that using the solution according to manufacturers instructions,
    and leaving the solution to ‘dry’ on the patient’s skin prior to incision
    will facilitate optimal ‘kill’ time and negate the need to a second ‘pass’
    with the solution.
    Best wishes

    Hi Michael,

    I currently don’t have access to the ACORN Standards to check what they
    are saying in the 2012 edition.

    However, as a trainee perioperative nurse, I was taught the principle was
    to prep from the proposed incision site to the edges of the operative
    field with one swab. This was then discarded as it was assumed to be
    heavily contaminated with skin organisms.

    A second swab was then used to apply the antiseptic to the area, once
    again starting at the proposed incision site and working outwards. This
    second pass was performed to ensure that the contact time of the
    antiseptic met manufacturer’s recommendations in addition to being thought
    to add to the antimicrobial activity against any organisms not contacted
    in the first episode of skin preparation.

    As Mathias rightly points out, achievement of the desired level of
    disinfection / skin antisepsis [as with sterilisation] is largely
    dependent on the initial number of organisms present. The more you start
    with the less likely you are to reduce their numbers sufficiently with
    just one application.

    Hi all

    Can I ask a question which may seem naive to those with a recent theatre background? When applying antiseptic solution as part of a surgical skin preparation prior to a procedure, is it best practice to apply two ‘coats’ of antiseptic solution, one immediately on top of the other, using different swabs?

    I can see not real benefit in doing this from an antiseptic action viewpoint (apart from mechanical friction) Can also not see this mentioned in a cursory review of any SSI prevention best practice guidelines.

    Any comments? Any references to get me up-to-date if I need to be updated?

    Michael and all

    In my research I am currently reviewing the draft US CDC Surgical Site Infection Guidelines which are due to be released in Nov 2013. They include comprehensive review of literature and rigorous grading of evidence for every recommendation. Guidance in this issue like many areas of infection prevention often becomes outdated due to new technologies and formulations. Misinterpretation, multi-resistant attitudes and holding onto sacred cows continue to plague effective clinical practice. The CDC draft statement regarding skin antisepsis suggests that multi applications may be one such sacred cow. The draft recommendation below is subject to normal HICPAC consultation processes.

    Always interesting to see how public policy evolves, usually much slower and less responsive than technology and adoption of trends and fads. All of this keeps our role exciting and very necessary.

    JUNE 2013 NEW

    8A. Require patients to shower or bathe (full body-including scalp) on at least the night before the operative day (Category IB)
    8A.1. No recommendation can be made regarding the safety and effectiveness of specific body cleansing products, the optimal timing or number of product applications. (No recommendation/unresolved issue)

    Thanks Cath, very interesting. But this appears to be about pre-op antiseptic body wash rather than pre-op skin antisepsis. Is there any proposed change to the HICPAC guidelines about skin antisepsis? Presume they will at least have a statement about following antiseptic manufacturer’s instructions for application?

    Cheers

    Michael and all

    In my research I am currently reviewing the draft US CDC Surgical Site Infection Guidelines which are due to be released in Nov 2013. They include comprehensive review of literature and rigorous grading of evidence for every recommendation. Guidance in this issue like many areas of infection prevention often becomes outdated due to new technologies and formulations. Misinterpretation, multi-resistant attitudes and holding onto sacred cows continue to plague effective clinical practice. The CDC draft statement regarding skin antisepsis suggests that multi applications may be one such sacred cow. The draft recommendation below is subject to normal HICPAC consultation processes.

    Always interesting to see how public policy evolves, usually much slower and less responsive than technology and adoption of trends and fads. All of this keeps our role exciting and very necessary.

    Hi all

    Can I ask a question which may seem naive to those with a recent theatre background? When applying antiseptic solution as part of a surgical skin preparation prior to a procedure, is it best practice to apply two ‘coats’ of antiseptic solution, one immediately on top of the other, using different swabs?

    I can see not real benefit in doing this from an antiseptic action viewpoint (apart from mechanical friction) Can also not see this mentioned in a cursory review of any SSI prevention best practice guidelines.

    Any comments? Any references to get me up-to-date if I need to be updated?

    Thanks
    Michael

    CDC does not typically drill down to the minutia level of applications. Under FDA and OSHA legislation I am sure that the assumptions rightly or wrongly are that manufacturers label as per their submission for registration and testing and that clinicians follow label instructions. Australia is no different.

    Below is an interesting point about intraoperative skin prep and solution of choice.

    There are also many in-press publications about CHG bathing pre-operatively as an additional measure.

    We have to remain on top of all this research and public policy and it’s very time consuming and not easy without formal training in reading and understanding scientific papers. Our lot in life I guess.

    JUNE 2013 UPDATED
    8B. Perform intraoperative skin preparation with an appropriate antiseptic agent. (Category IA)

    Thanks Cath, very interesting. But this appears to be about pre-op antiseptic body wash rather than pre-op skin antisepsis. Is there any proposed change to the HICPAC guidelines about skin antisepsis? Presume they will at least have a statement about following antiseptic manufacturer’s instructions for application?

    Hi Cath, hi Michael,

    I agree with Michael — not that Cath was fundamentally different on that issue — that (a) classical skin antisepsis before surgical incision (‘surgical skin prep’) and (b) antiseptic body washing or showering in the preoprerative phase (that includes preoperative antiseptic body wiping with cloths) are two fundamentally different processes, both biologically and clinically.

    Classical skin antisepsis is extremely well supported by evidence plus carries a clear scientific rationale:
    (1) Historically, skin antisepsis before iatrogenic skin breaks has been used since the 1890s (e.g. a paper by Harrington & Walker 1903 stated it was in widespread use).
    (2) There is a clear biological and microbiological theoretical framework supporting it, i.e. there is biological plausibility. This includes the fact that well-conducted skin antisepsis reduces microbe counts on skin by anywhere between 2 log and 4 log (a factor of 100-10,000) and that microorganisms from patients’ skin are known to cause surgical site infections.
    (3) That based on microbiological testing — both in reagent tubes and on real skin — antiseptics can be categorised (that includes regulatory purposes by product approval agencies) into stronger and weaker ones, and some that pass standards and others that don’t.
    (4) That outcomes from clinical trials, including very well conducted (i.e. high-level evidence) randomised clinical trials by and large reflect the outcomes from microbiological testing.
    So, we have various angles of strong support here.

    Preoperative antiseptic body washing is much less supported overall. This is also reflected by the statement in the draft text passage that Cath sent, saying that although showering or bathing should be done (note, no antiseptic stated here), it says “No recommendation can be made regarding the safety and effectiveness of specific body cleansing products, the optimal timing or number of product applications.” That means the draft does not necessarily imply that this should be done with antiseptics. The use of antiseptics for that purpose follows a reasonably good rationale and has biological plausibility, but support from high-quality randomised clinical trials is currently lacking. The latter also became clear in a recently-updated Cochrane review by Webster & Osborne (authors from QLD) in 2012. Microbiologically, antiseptic body washing achieves far lesser microbial reduction on skin than classical skin antisepsis. There are several other non-randomised (e.g. observational) clinical studies showing a benefit from antiseptic washing, and they should definitely not be discounted. These are still providing valuable evidence. But the evidence from the latter type of studies is not quite as clear-cut as one would wish, just as an example, by coincidence there were two almost back-to-back recently-appeared (but in different journals) papers, one by Kapadia et al. 2013, the other by Farber et al. 2013. One was antiseptic-industry-supported, the other not. The industry-supported paper showed a benefit, the other not. Just a few interesting observations here . . .

    Best regards, Matthias.

    Hi Cath, hi Michael,

    I agree with Michael — not that Cath was fundamentally different on that issue — that (a) classical skin antisepsis before surgical incision (‘surgical skin prep’) and (b) antiseptic body washing or showering in the preoprerative phase (that includes preoperative antiseptic body wiping with cloths) are two fundamentally different processes, both biologically and clinically.

    Classical skin antisepsis is extremely well supported by evidence plus carries a clear scientific rationale:
    (1) Historically, skin antisepsis before iatrogenic skin breaks has been used since the 1890s (e.g. a paper by Harrington & Walker 1903 stated it was in widespread use).
    (2) There is a clear biological and microbiological theoretical framework supporting it, i.e. there is biological plausibility. This includes the fact that well-conducted skin antisepsis reduces microbe counts on skin by anywhere between 2 log and 4 log (a factor of 100-10,000) and that microorganisms from patients’ skin are known to cause surgical site infections.
    (3) That based on microbiological testing — both in reagent tubes and on real skin — antiseptics can be categorised (that includes regulatory purposes by product approval agencies) into stronger and weaker ones, and some that pass standards and others that don’t.
    (4) That outcomes from clinical trials, including very well conducted (i.e. high-level evidence) randomised clinical trials by and large reflect the outcomes from microbiological testing.
    So, we have various angles of strong support here.

    Preoperative antiseptic body washing is much less supported overall. This is also reflected by the statement in the draft text passage that Cath sent, saying that although showering or bathing should be done (note, no antiseptic stated here), it says “No recommendation can be made regarding the safety and effectiveness of specific body cleansing products, the optimal timing or number of product applications.” That means the draft does not necessarily imply that this should be done with antiseptics. The use of antiseptics for that purpose follows a reasonably good rationale and has biological plausibility, but support from high-quality randomised clinical trials is currently lacking. The latter also became clear in a recently-updated Cochrane review by Webster & Osborne (authors from QLD) in 2012. Microbiologically, antiseptic body washing achieves far lesser microbial reduction on skin than classical skin antisepsis. There are several other non-randomised (e.g. observational) clinical studies showing a benefit from antiseptic washing, and they should definitely not be discounted. These are still providing valuable evidence. But the evidence from the latter type of studies is not quite as clear-cut as one would wish, just as an example, by coincidence there were two almost back-to-back recently-appeared (but in different journals) papers, one by Kapadia et al. 2013, the other by Farber et al. 2013. One was antiseptic-industry-supported, the other not. The industry-supported paper showed a benefit, the other not. Just a few interesting observations here . . .

    Best regards, Matthias.

    CDC does not typically drill down to the minutia level of applications. Under FDA and OSHA legislation I am sure that the assumptions rightly or wrongly are that manufacturers label as per their submission for registration and testing and that clinicians follow label instructions. Australia is no different.

    Below is an interesting point about intraoperative skin prep and solution of choice.

    There are also many in-press publications about CHG bathing pre-operatively as an additional measure.

    We have to remain on top of all this research and public policy and it’s very time consuming and not easy without formal training in reading and understanding scientific papers. Our lot in life I guess.

    8B. Perform intraoperative skin preparation with an appropriate antiseptic agent. (Category IA)
    8B.1.a. Use chlorhexidine gluconate-alcohol in preference of aqueous iodophor skin preparation, unless contraindicated. (Category IA)
    8B.1.b. No recommendation can be made regarding the safety and effectiveness of chlorhexidine gluconate-alcohol as compared to iodophor-alcohol skin preparation.(No recommendation/unresolved issue)

    Cheers

    Thanks Cath, very interesting. But this appears to be about pre-op antiseptic body wash rather than pre-op skin antisepsis. Is there any proposed change to the HICPAC guidelines about skin antisepsis? Presume they will at least have a statement about following antiseptic manufacturer’s instructions for application?

    Cheers

    Michael and all

    In my research I am currently reviewing the draft US CDC Surgical Site Infection Guidelines which are due to be released in Nov 2013. They include comprehensive review of literature and rigorous grading of evidence for every recommendation. Guidance in this issue like many areas of infection prevention often becomes outdated due to new technologies and formulations. Misinterpretation, multi-resistant attitudes and holding onto sacred cows continue to plague effective clinical practice. The CDC draft statement regarding skin antisepsis suggests that multi applications may be one such sacred cow. The draft recommendation below is subject to normal HICPAC consultation processes.

    Always interesting to see how public policy evolves, usually much slower and less responsive than technology and adoption of trends and fads. All of this keeps our role exciting and very necessary.

    JUNE 2013 NEW

    8A. Require patients to shower or bathe (full body-including scalp) on at least the night before the operative day (Category IB)
    8A.1. No recommendation can be made regarding the safety and effectiveness of specific body cleansing products, the optimal timing or number of product applications. (No recommendation/unresolved issue)

    Hi all

    Can I ask a question which may seem naive to those with a recent theatre background? When applying antiseptic solution as part of a surgical skin preparation prior to a procedure, is it best practice to apply two ‘coats’ of antiseptic solution, one immediately on top of the other, using different swabs?

    I can see not real benefit in doing this from an antiseptic action viewpoint (apart from mechanical friction) Can also not see this mentioned in a cursory review of any SSI prevention best practice guidelines.

    Any comments? Any references to get me up-to-date if I need to be updated?

    Thanks
    Michael
