    Hi All,

    There is still an ongoing debate whether we should use an alcohol swab before administering clexane, vaccines and insulin. Any ideas please?
    I know the latest practice in regards administering clexane is to “not swab”.

    I just want to advise my team from a infection control point of view with facts to stand on.

    Hi Franciska,

    The Australian Immunisation Handbook 9th states 1.4.4 page 43 “provided the skin is visibly clean” no swabbing is required. If need be using an alcohol wipe is to be used, allow drying time before administering vaccination.

    I am not aware of any other recommendations for skin preparation for IM / SC route.

    Hi Franciska
    The immunization guidleines reflect that swabbing of skin is not
    recommended for vaccines unless the injectable area is dirty – see link
    http://www.immunise.health.gov.au/internet/immunise/publishing.nsf/Conte
    nt/Handbook-home
    Section 1.4.4 – Provided the skin is visibly clean, there is no need to
    wipe it with an antiseptic (eg. alcohol wipe).3,4 If the immunisation
    service provider decides to clean the skin, or if the skin is visibly
    not clean, alcohol and other disinfecting agents must be allowed to dry
    before vaccine injection (otherwise there may be some increased
    injection pain).

    Hope that helps

    Dear Franciska,

    Not sure about clexane and insulin (s.c. injections), but I have looked in some detail into the current Australian recommendations concerning vaccinations. Most vaccinations are i.m. injections, which are biologically quite different from s.c. injections and also from venipuncture. The official recommendation by the Australian Immunisation Handbook is not to swab (so if you follow that, you are following official recommendations), and only to swab if the injection area is visibly dirty, but the problem is that these recommendation are severely misguided and intellectually flawed.

    (1) Much of it is based on a short 2001 article in the MJA, examining a few hundred s.c. injections and venipunctures, and concluding that swabbing for ANY type of injection is not necessary, including i.m. injections. There are two fatal flaws with this assumption. (a) The article did not examine even a single i.m. injection and made conclusions pertaining to these (which is inconsistent with the principles of evidence-based medicine, which the article purported to adhere to), and (b) the natural infection rate after i.m. injections is very low, estimated to be in the range of 1:5000 to 1:10000 or less (which is reassuring), but if you study a smaller population than is needed to capture the natural incidence of an event, then you cannot make conclusions that the intervention has no effect on the occurrence of the event.

    (2) The recommendation to swab only if visibly soiled is not justified either, because microorganisms are invisible, and implementing this as a cutoff between swabbing and non-swabbing is arbitrary without a scientific base or evidence base. Imagine you sit in front of a patient with a darker skin colour and want to give an injection. When would you be confident that the skin is NOT visibly dirty?

    In summary, if you don’t swab, you are consistent with the guidelines, but the guidelines are seriously flawed (at least you won’t be responsible then). It is certainly reassuring that the natural infection rate is very low, and statistically you are unlikely (but it is possible) to see any adverse event. It is clear that i.m. injections and other types of injections are biologically and clinically different and bear a different infection risk. Also, the deeper an injection is, the more complicated infections can get (examples on the complicated end are joint injections, corticosteroid injections, or more complicated injections).

    Best regards, Matthias.

    I completely agree with you Matthias.

    With injections into IV ports we are now encouraged to “scrub the hub” for
    30 seconds with either isopropyl alchol or alcoholic chlrohexidine etc!

    Yet for the skin, which is nice and warm and moist – capable of supporting
    much higher microbe counts than a dry cool rubber bung, we use
    nothing…bizarre!!!

    Behalf Of Matthias Maiwald (KKH)

    Dear Franciska,

    Not sure about clexane and insulin (s.c. injections), but I have looked
    in some detail into the current Australian recommendations concerning
    vaccinations. Most vaccinations are i.m. injections, which are
    biologically quite different from s.c. injections and also from
    venipuncture. The official recommendation by the Australian Immunisation
    Handbook is not to swab (so if you follow that, you are following
    official recommendations), and only to swab if the injection area is
    visibly dirty, but the problem is that these recommendation are severely
    misguided and intellectually flawed.

    (1) Much of it is based on a short 2001 article in the MJA, examining a
    few hundred s.c. injections and venipunctures, and concluding that
    swabbing for ANY type of injection is not necessary, including i.m.
    injections. There are two fatal flaws with this assumption. (a) The
    article did not examine even a single i.m. injection and made
    conclusions pertaining to these (which is inconsistent with the
    principles of evidence-based medicine, which the article purported to
    adhere to), and (b) the natural infection rate after i.m. injections is
    very low, estimated to be in the range of 1:5000 to 1:10000 or less
    (which is reassuring), but if you study a smaller population than is
    needed to capture the natural incidence of an event, then you cannot
    make conclusions that the intervention has no effect on the occurrence
    of the event.

    (2) The recommendation to swab only if visibly soiled is not justified
    either, because microorganisms are invisible, and implementing this as a
    cutoff between swabbing and non-swabbing is arbitrary without a
    scientific base or evidence base. Imagine you sit in front of a patient
    with a darker skin colour and want to give an injection. When would you
    be confident that the skin is NOT visibly dirty?

    In summary, if you don’t swab, you are consistent with the guidelines,
    but the guidelines are seriously flawed (at least you won’t be
    responsible then). It is certainly reassuring that the natural infection
    rate is very low, and statistically you are unlikely (but it is
    possible) to see any adverse event. It is clear that i.m. injections and
    other types of injections are biologically and clinically different and
    bear a different infection risk. Also, the deeper an injection is, the
    more complicated infections can get (examples on the complicated end are
    joint injections, corticosteroid injections, or more complicated
    injections).

    Best regards, Matthias.

    Behalf Of Franciska Ferreira

    Hi All,

    There is still an ongoing debate whether we should use an alcohol swab
    before administering clexane, vaccines and insulin. Any ideas please?

    I know the latest practice in regards administering clexane is to “not
    swab”.

    I just want to advise my team from a infection control point of view
    with facts to stand on.

    Kind Regards

    Actually, although this is strictly unproven (only anecdotal), direct access to a blood vessel and then removing the needle, such as in venipuncture or i.v. injection, presumably has a lower risk of infection than injecting into tissue, because in tissue it takes a while for defense cells to reach it. What makes vascular catheters and i.v. cannulas (that stay in) more problematic than clean, one-off access into blood vessels is that you have (a) hardware that stays in place, and (b) a continuing skin breach over several days, from which the organisms can enter.

    From the 1999 CDC surgical site infection guideline, the conceptual framework for the risk of surgical site infections is:

    Dose of bacterial contamination x virulence
    ——————————————————- risk of surgical site infection
    resistance of the host patient

    (Hope the display of the equation comes across OK).

    This would similarly apply to injections, although all the parameters involved are different from those in surgery.

    If you look at a recent article from MJA:

    http://www.ncbi.nlm.nih.gov/pubmed/23496408

    even though the inoculum in the injection and the virulence was probably very (!) low, there were two factors that decreased the host resistance, (a) prosthetic joint (hardware) in place, and (b) a large volume (8 mL) of injected fluid, which makes drainage of the fluid from the injected site difficult, and therefore a very small inoculum can cause an infection.

    in fact, I have quite a nice bruise the size of a 5c piece after my flu needle, which bears out my theory that supposed IM injections can be exposed directly to the bloodstream quite nicely! (although I would rather they didn’t)

    Hi Claire

    I, too, agree with Matthias, but I do not think your comparison with IV access is correct. Giving a sub-cut or IM injection has a much lesser risk of infective complications than any direct access to the blood stream (such as IV access or phlebotomy, for example). In my own practice I currently still use alcohol swabs prior to IM vaccination as it is quick, cheap and not worth the potential infective risk (which is yet to be well quantified as pointed out by Matthias).

    If patients are self-injecting (either sub-cut or IM), then the risk from auto-inoculation with their own flora may be even lower (viz self-catheterisation guidelines), so I would have no issues with teaching patients not to swab their own skin prior to a simple injection (as long as they were not directly injecting into a vein or device, though). The evidence supporting this is also pretty scant, though.

    Cheers

    I completely agree with you Matthias.

    With injections into IV ports we are now encouraged to “scrub the hub” for 30 seconds with either isopropyl alchol or alcoholic chlrohexidine etc!

    Yet for the skin, which is nice and warm and moist – capable of supporting much higher microbe counts than a dry cool rubber bung, we use nothing…bizarre!!!

In my own practice I currently still use alcohol swabs prior to IM vaccination as it is quick, cheap and not worth the potential infective risk (which is yet to be well quantified as pointed out by Matthias).

    If patients are self-injecting (either sub-cut or IM), then the risk from auto-inoculation with their own flora may be even lower (viz self-catheterisation guidelines), so I would have no issues with teaching patients not to swab their own skin prior to a simple injection (as long as they were not directly injecting into a vein or device, though). The evidence supporting this is also pretty scant, though.

    Cheers

    I completely agree with you Matthias.

    With injections into IV ports we are now encouraged to “scrub the hub” for 30 seconds with either isopropyl alchol or alcoholic chlrohexidine etc!

    Yet for the skin, which is nice and warm and moist – capable of supporting much higher microbe counts than a dry cool rubber bung, we use nothing…bizarre!!!

    Dear Franciska,

    Not sure about clexane and insulin (s.c. injections), but I have looked in some detail into the current Australian recommendations concerning vaccinations. Most vaccinations are i.m. injections, which are biologically quite different from s.c. injections and also from venipuncture. The official recommendation by the Australian Immunisation Handbook is not to swab (so if you follow that, you are following official recommendations), and only to swab if the injection area is visibly dirty, but the problem is that these recommendation are severely misguided and intellectually flawed.

    (1) Much of it is based on a short 2001 article in the MJA, examining a few hundred s.c. injections and venipunctures, and concluding that swabbing for ANY type of injection is not necessary, including i.m. injections. There are two fatal flaws with this assumption. (a) The article did not examine even a single i.m. injection and made conclusions pertaining to these (which is inconsistent with the principles of evidence-based medicine, which the article purported to adhere to), and (b) the natural infection rate after i.m. injections is very low, estimated to be in the range of 1:5000 to 1:10000 or less (which is reassuring), but if you study a smaller population than is needed to capture the natural incidence of an event, then you cannot make conclusions that the intervention has no effect on the occurrence of the event.

    (2) The recommendation to swab only if visibly soiled is not justified either, because microorganisms are invisible, and implementing this as a cutoff between swabbing and non-swabbing is arbitrary without a scientific base or evidence base. Imagine you sit in front of a patient with a darker skin colour and want to give an injection. When would you be confident that the skin is NOT visibly dirty?

    In summary, if you don’t swab, you are consistent with the guidelines, but the guidelines are seriously flawed (at least you won’t be responsible then). It is certainly reassuring that the natural infection rate is very low, and statistically you are unlikely (but it is possible) to see any adverse event. It is clear that i.m. injections and other types of injections are biologically and clinically different and bear a different infection risk. Also, the deeper an injection is, the more complicated infections can get (examples on the complicated end are joint injections, corticosteroid injections, or more complicated injections).

    Best regards, Matthias.

    Hi All,

    There is still an ongoing debate whether we should use an alcohol swab before administering clexane, vaccines and insulin. Any ideas please?

    I know the latest practice in regards administering clexane is to not swab.

    I just want to advise my team from a infection control point of view with facts to stand on.

    Kind Regards
