Tri-Assess Wound Care EMR stacks up well versus Wound Expert

I have had the chance to work with my friend (and nationally recognized wound guru) Cathy Thomas Hess over the last few months. We have been developing the seventh edition to her TRi-Assess wound and hyperbaric management EMR.  I have had the opportunity (in my history as a wound care clinician) to have used several wound management EMRs (including Wound Expert).  The significant difference from those EMRs to TRi-assess 7.0 is  the comprehensive, yet  intuitive flow of TRi-assess 7.0.  Tri-Assess 7.0 will also be ready to be certified as a full ambulatory solution meeting meaningful use requirements in the second quarter of this year. This is apparently in line with other wound related electronic medical records such as wound expert (woundexpert) and intellicure. If you are looking for a wound EMR system such as intellicure or wound expert (woundexpert) take a look at www.woundcarestrategies.com . I think you will be pleased with what she has to offer.

Best Wishes,

Wound VAC Placement Tips

This is a list of wound VAC tricks that I have learned over the years. These tips will make your dressing change go faster with longer lasting results.

1. Cutting Foam – I typically use a number ten blade to cut the foam and drape. The drape can be a little tough to cut with a  blade so you may want to work with scissors.

2. Sizing the Foam – I size the wound with my gloved finger then bring it over to the foam. Cutting a mark in the foam for the horizontal line, then repeating the process for the vertical line. Always make the foam a little smaller (than the wound opening) to allow for contraction.

3. Corners or Bridging – Cutting the foam in half makes the foam more workable around corners or when bridging. This is best done with a 10 blade (as always watch your fingers).

4. Leaks – Check the connections (sometimes they crack). Listen for leaks with your stethoscope. Rub skin prep along the edges to paste down any open drape. Drape over any suspect areas.

5. Small Wounds - For smaller wounds surround the wound edges with a hydrocolloid (duoderm thin) or VAC drape to reduce the risk of foam suction trauma on normal tissue.

6. Difficult Contours – Stoma paste is useful for the filling in difficult contours or skin folds so the VAC drape can sit over a flatter surface, and maintain a seal. Make sure the stoma paste is dry before turning on the VAC or else it will suck the paste inward.

7. Protecting – Cover and protect weakened, irradiated or sutured blood vessels or organs with Silicone or other type of non-contact layer (Mepitel – Molnlycke or Conformant 2 Wound Veil – Smith & Nephew).

8. Pain Reduction- Mepitel and Wound Veil,  is also very useful for patients who have pain with VAC foam removal. If this is the case, place a narrow strip of the non contact sheet along the top line of wound tissue ( closest to the skin). This prevents the foam from getting caught in the most innervated tissue.

Instill 1% lidocaine into the tubing and foam 30 minutes prior to removal of the foam from the wound bed. Use adhesive remover to lift the drape to reduce tape burn. Give pain medication prior to removal of the foam dressing.

9. Large Wounds – Contract larger wounds by cutting the VAC foam smaller than the wound. Then, after securing the drape to one side of the wound edge, pull the drape over the VAC foam. At the same time push (with care) the undraped wound edge towards the wound bed and sponge. Finally, lay the drape down on the undraped side a few cm at a time while slowly moving the tension providing hand out from under the drape.

10. Rash - If the skin is reactive (rash) to the VAC drape use duoderm thin as the first layer. Make as small of a VAC drape foot print as possible (so that none of the drape adheres to the skin, only over the duoderm).

11. Small opening Large undermining -  This trick is called the “cinnamon bun”. First, cut a spiral in the foam. Then feed the spiraled foam into the wound opening, leaving a few inches on top to secure the dressing.

12. Legal - With a black sharpee write on the VAC drape how many pieces were used.

Multilayer Compression Tips (What to do under the wraps)

Here are pathways for treating and protecting skin and wounds under multilayer compression bandaging (Profore or dynaflex) for patients with venous hypertension: Please add to this list as you wish. This was last revised  06/25/2010.

Dry Skin

Dry flakey skin – Moisturizer or thicker moisturizer.

Dry denuded skin – Xeroform.

Dry lightly reddened skin – A moderate strength steroid  (Topicort), change underlying padding to pure cotton cast padding.

Dry itching burning skin – Viscopaste wrap as first layer.

Moist Skin

Moist denuded skin – wound veil (Smith and nephew) covered with alginate. I recommend the wound veil cover because it will prevent the alginate from binding with the denuded tissue.

Draining wound – alginate or a beveled foam dressing. Note that foams have a tendency to dig into the skin around the edges, so it is important cut and taper around the foam edges.

What antimicrobials can I place on the wound that will last seven days?

Moderate or High draining wounds – Consider Iodosorb or Acticoat 7  flex. Remember to put lots of protective cream (EPC) around the peri-wound. Consider changing the  compression wrap twice a week.

The dressing has a foul smell after a few days

Consider a carbon dressing over the primary antimicrobial, debride, treat infection if present, change the dressing more often.

Still Edematous

Swollen moist red skin with new breakdown (even with 30-40mmHg compression) – Typical with fluid over load patients including renal disease. Treat the  etiology.

Swollen extremity with reddened skin and new onset calf pain – Rule out DVT.

Edematous knee to thigh after compression – Rule out Lymphedema and consider Edema Wear or Tubigrip from the bottom of the knee (just below the top of the initial compression device) to the top of the thigh. Consider placing a strip of foam dressing just under and over the top of the multilayer compression device if the top of the compression dressing is cutting into the skin (because of the edema).

Swollen Forefoot after Compression – Typically this is a result of the compression dressing being pushed up by mechanical means (related to poor fitting shoes or human intervention). Recommend the patient wear shoes with larger toe space such as Crocs or a surgical shoe. Consider placing an extra turn of the wrap or a 4×4 of plain foam over the  swollen area. Also place a thick barrier cream such as EPC cream over the forefoot to provide some tact in the area.

Swollen Toes after Compression – Consider gently wrapping the toes by first separating each toe with a foam dressing to prevent toe to toe pressure. Then place extra padding over the toes before you finish wrapping the toes with Coban. The elastic layer shouldn’t be placed over the toes along with the Coban,  as this my apply to much pressure.

Infection

Swollen red skin with open wound and new onset fever or pus – Rule out infection, culture wound, antibiotics.

Inflammation

Bright reddened skin   (Inflammatory with no signs of infection) – Topicort topical, medrol dose pack, Could also be related to allergy such as sulfa, bacitracin, or latex. Note that redness from a topical sulfa allergy can clear up in a matter of minutes once removed.

Recurrent reddened skin with an open non-healing wound  – Consider differential diagnosis including autoimmune or another micro-occlusive disorder. Micro-occlusive disorders are covered in the Scottsdale Wound Management Guide (which can be purchased at swmghandbook.com). – Topicort to the wound bed and Prednisone oral weening over 6 weeks.

Dermatology

Reddened vessels around hair follicles – Rule out  folliculitus

Smaller reddened vessels (in groups or singular) – Consider treatment as fungal infection. Anti-fungal ointment for small area fungal breakouts.

Itchy rash over the majority of lower extremity below and maybe just above the knee to the thigh  (If using latex compression  wraps) , also possible systemic effects including puffy face, etc… – Rule out latex allergy, Consider Medrol dose pack, Benadryl, and Profore LF (Latex Free)

Shriveled skin – This is a common situation which happens during the first few weeks of compression therapy. The skin typically tightens on its own.

Adherent dry or dead tissue build up – Lotions (without alcohol)  and /or mist therapy to loosen. Once loose use a pick-up to remove.

Pain

Vague recurrent pain with application of compression dressing – To much tension, consider less compression to the extremity. Including placing Tubigrip instead of Coban on the final layer. Insure that ABI indicates no arterial component.

Recurrent pain over bone with the application of compression dressing – Assess the skin for areas of bruising or open skin. Cover the area with a hydrocolloid.

Recurrent pain over small protruding bone with the application of compression dressing – Cut out foam around the prominence with the idea of offloading the small protruding bones from the pressure of the wrap.

Recurrent pain over prominent shin bone with the application of compression dressing – Build up an offloading  layer of cast padding to the shins sides, then place extra cast padding over the shin down to the anterior ankle .

Pain related to wrap cutting in to skin of fluted lower extremity.  Note that fluted refers to a thick upper calf and a narrow distal third of the lower extremity – Assess for rolled undulating skin with straight indentations or openings into the skin that match up with the wrap. Place extra cotton layers around the lower third of the dressing to build the area up. This protects the skin and helps prevent the wrap from sliding down.

Swollen extremity with reddened skin and new onset calf pain – Rule out DVT

Pain with removal of dressing – Consider using Xeroform,  Adaptic, Mepetel or Comfort 2 Wound Veil.  Saturate the dressing with saline to facilitate removal of dry drainage from viable tissue.

No Improvement in Wound Size:

Consider a vascular consultation starting with a Venous Doppler R/O incompetent perforators.

Consider if wound stalling is related to chronicity or infection. Treat with collagen and /or with seven day anti-microbal dressing.

Consider secondary etiologies such as lymphedema, hypercoagulable states, autoimmune disorders, malignancy, etc…

Unable to convert patient to stockings (without increased swelling and or reopening of wounds)

Consider a vascular consultation starting with a Venous Doppler R/O incompetent perforators.

Try different compression stocking companies including more expensive brands that may have true and appropriate compression(yes there is a difference in quality between brands).

Poor health precludes vascular intervention – Palliative care (keep the patient in multilayer compression).
