Publications

SMTL manage a number of websites which publish articles, test reports and general information related to medical devices.

For more information, see the articles below.

SMTL had reported previously that high MVTR dressings, when tested using the ’fluid in contact’ method in EN 13726-1, Monograph 3.3 (Fluid handling capacity) and EN 13726-2 Mongraph 3.3 (MVTR of a wound dressing when in contact with liquid), caused doming of the dressing into the test chamber. It was suspected that this doming artificially increased the reported MVTR and FHC due to stretching of the dressing.

SMTL proposed that the inclusion of a small vent holes in the Paddington cups seemed sensible, as it may prevent the doming observed with high MVTR dressings.  SMTL and the SDMA  agreed that work should be undertaken to investigate this. A series of experiments were discussed and agreed between SMTL and SDMA members over the Winter 2012/Spring 2013, and a test programme
was run in 2013.

The report "MVTR Interlab Testing - SMTL/SDMA - 2013 - PID/4319" (PDF) reports the outcome of this work programme.

The work has now been accepted by CEN WG15 PGQ1 and a revision of EN 13726 is underway.

During the review of EN 13726, it was noted that sometimes the required specification of the gelatin was not
available, and the question arises as to the effect the bloom has on the results.

SMTL have undertaken 2 tests with the same product (from 2015)  but using two different bloom gelatins, and the analyses is available as a PDF report.  

 

At the CEN TC 205 WG15 meeting in London in June 2015, a discussion took place on whether the requirement to wait for 30 minutes before weighing test chambers from a 37C incubator was necessary.

SMTL undertook a series of experiments to investigate this, and the report is available as a PDF download.

 

SMTL's dressings datacards web site (http://www.dressings.org) is dedicated to providing a repository of independently authored datacards and test reports on surgical dressings and bandages.

The dressings datacards (http://www.dressings.org/dressings-datacards-by-alpha.html) are highly valued by nurses involved in woundcare, as they provide a rapid summary of indications, method of use, range of size available etc.

As you are probably aware, placement of a woundcare product onwww.dressings.org virtually guarantees a high Google ranking. By sponsoring a datacard, you are able to have a link placed on the manufacturers name and the dressing name to any specified site of your choice, which can drive additional traffic to your site and help your Google ranking.

To get your dressing added to www.dressings.org we need the following from you:

  • peer reviewed papers (where possible)
  • technical product information
  • product samples, including product in its original packing (2 samples is usually sufficient)
  • primary contact email address of the person who will agree the datacard

Each datacard is written by an experienced author in the field. The datacard will be sent to you for review before it goes live, but please note that the datacards are an independent publication of SMTL, and that the final decision on the content of the datacards is SMTL's.

The price for each datacard is as follows:

New datacards - £825

If you already have dressings datacards on www.dressings.org, you can have them amended to reflect current packaging, changes in indications etc.

Major Revisions - £550

Minor Revisions - £275

Please send the dressing information to:

Pete Phillips SMTL Princess of Wales Hospital Coity Road Bridgend CF31 1RQ United Kingdom

You can also email me the product information if it is available electronically.

I look forward to hearing from you,

Yours Sincerely Peter Phillips SMTL

If you commission testing at SMTL, you have the option of having your test report published in Medidex.

Medidex includes  scientific communications based upon data generated by the SMTL as part of its commercial testing activities. The documents may take one of two forms.

  1. The simplest is a copy of the original technical report which contains a brief description of the test methods used together with the test results. Competitor products used as a comparator may be suitably anonomised if thought necessary.
  2. The alternative presentation consists of the same test data together with some narrative that might discuss the clinical relevance of the results or provide some form of discussion or conclusions.

All these documents are included on the site at the specific request of the commissioning organisation but are only published if they meet certain strict criteria as identified below.

  • All test data must be generated by SMTL.
  • All the results generated during the course of the testing programme must be published.
  • Companies are not permitted to selectively exclude unfavourable results or findings from a report prior to publication.
  • Where narrative is included in a publication this will normally be produced by SMTL staff and associates, although the SMTL may, at their absolute discretion, choose to accept material written by external authors who are recognised for their expertise in their field

Furthermore SMTL will not knowingly publish incorrect or misleading data involving the use of inappropriate comparators which show the test material in an artificially good light. The SMTL also reserves the right to refuse to publish data that is known to be unrepresentative of the performance of a particular product.
