Wilson exposes Deprox fraud!

Deprox Hygiene Solutions

In a letter published today in the Journal of Hospital Infection, Professor Peter Wilson and colleagues report on their retesting of the Deprox (Hygiene Solutions Ltd) HPV decontamination system. The retesting was in response to concerns widely raised that the earlier tests of the system, which purported to give a log 6 efficacy, were the result of the manufacturer misrepresenting the concentration and/or constituents of the Deproxin solution.

In brief, the retest reveals the following:

  • The efficacy of the system, when using the correct 5% H2O2 solution, is around log 4 – similar to other, much less expensive fogging systems on the market. Hygiene Solutions Ltd will now be taxed to explain why on the initial test by Prof. Wilson, a log 6 efficacy was found. This 100 fold drop in efficacy comes between the first test series, in which the solution concentration was not checked, and the second series in which the concentration was independently measured. It seems highly likely that in the initial test series, the Deprox was running on a 30% H2O2 solution, rather than a 5% H2O2 solution as claimed.
  • The aerial H2O2 concentration on re-entering the room at the end of the cycle was 3.3ppm which is in excess of both short term and long term H2O2 exposure health limits. This is in spite of a hasty retrofit of catalysts to the whole Deprox fleet, and the manufacturer’s claim that their system monitored the H2O2 levels, and would only allow re-entry when the level was below the 1ppm safety standard.
  • Deproxin is confirmed to contain 10-20ppm silver nitrate, and this is indeed deposited on surfaces in the room, and may well be a contributor to the efficacy achieved. Hygiene Solutions informed the HSE over a year ago that Deproxin does not contain silver nitrate. This has now been exposed as untrue – and raises the question as to whether it is currently legal to sell or use the Deprox system.
  • Poor efficacy results for two more sheltered locations is attributed to homogeneous vapour distribution, due to inadequate circulation of the vapour. This raises serious doubts as to Hygiene Solutions’ claims that the Deprox will decontaminate “inside small crevices and complex equipment”

It is very much to the credit of Professor Wilson and colleagues that they have thoroughly retested the system in response to widespread concerns. It is sad that commercial interests would abuse the trust and confidence of highly qualified academics in this way by misrepresenting the basic test parameters.

For those without access to the Journal of Hospital Infection, I have reproduced the letter below:

Sir,

In response to the letter from Dr Singh commenting on our paper.[1], [2]

The objective of our study was to evaluate the reductions in environmental contamination during in-use operation of two commercially-available hydrogen peroxide whole-room disinfection systems.2 Both manufacturers agreed test parameters prior to the trial to ensure methodology followed manufacturer instructions. Our findings suggested similar efficacy of the two systems against both surface contamination and biological indicators of common pathogens. Inocula used on the indicators far exceeded the likely levels seen in the environment.

Additional studies were performed as part of the original work using the same methodology with four strains each of MRSA, Klebsiella pneumoniae, Clostridium difficile spores and Acinetobacter baumannii. Three HPV decontamination cycles were evaluated for each system. Of 305/320 samples, >4-log10 reduction was achieved.

Aerial concentrations of hydrogen peroxide and relative humidity were monitored continuously during a further 6 cycles of both systems using a sensor (C-16 Portasens II Gas Detector; Analytical Technology Inc., Collegeville, PA, USA). In addition, horizontal surfaces in the near-patient vicinity were swabbed and analysed to detect fallout of silver and nitrate at the end of HPV decontamination cycles (n=3). Surfaces were swabbed and analysed for silver by titration (Silver Test Kit, DTK Water, Wellingborough, UK) and nitrate using Quantofix semi-quantitative test strips (Macherey-Nagel, Düren, Germany).

For the Deprox (Hygiene Solutions, King’s Lynn, UK) system, peak aerial values of 29-46 ppm hydrogen peroxide were achieved with similar bacteriological efficacy as other cycles. The mean level at the end of the cycles was 3.3ppm for 41.8% (30.8-58.1%) mean relative humidity at start of cycles. Silver and nitrate were detected on surfaces at 1.5-2.5mg/m2 following cycles with the Deprox system.

For the Bioquell Q10 system with the R10 aeration unit (Bioquell, Andover, UK), the peak aerial levels of hydrogen peroxide were 450-640ppm. The mean level at the end of the cycles was 0.0ppm with starting mean relative humidity 42.5% (34.5-49.7%). No silver or nitrate was detected on surfaces following cycles with the Bioquell Q10 system.

The aqueous concentration of hydrogen peroxide in a Hygiene Solutions cartridge (Deprox) tested on one occasion at the point of insertion into the machine was 5%. Nitrate was detected in the aqueous solution at 10-25mg/L. The aqueous hydrogen peroxide concentration in the Bioquell Q10 cartridge (Bioquell HPV-AQ) was 35% and no silver or nitrate was detected.

Dr Singh suggests C. difficile spores (but not the other organisms) persisted underneath the bed and on the window frame after decontamination using the Deprox system. The persistence of spores may have been minimised during the Bioquell Q10 cycles by the inclusion of an oscillating fan to facilitate aerial distribution and aid breakdown of hydrogen peroxide vapour.

As Dr Singh suggests, settling of active silver onto biological indicator coupons during a cycle of aerial HPV decontamination may have contributed to the bactericidal/sporicidal activity of the Deprox system. However further studies would be required to elucidate its role.

Profiteers playing with fire..

Deprox PBCC

(OK, it’s off topic, but this is another deeply disturbing example of profits being put ahead of safety, and commercial exploitation of weak or inadequate government  regulation)

Dr Ecosse

Fairview Architectural, a Unispec brand whose UK distributor is Valcan Ltd, posted a news item bragging that they secured the contract to replace the burnt out polyethylene core cladding responsible for a terrifying 2014 tower fire in the Lacrosse Apartments in Melbourne, Australia.

Incredibly, in spite of this first hand experience of the danger of polyethylene cored panels, the same company supplied their polyethylene core Vitrabond panels to the Evenlode and Windrush residential tower blocks in Oxford UK, through its UK office, Valcan Ltd. – and bragged about that too!

According to a recent article in The Telegraph, the polyethylene core burns like petrol:

Now, according to the Oxford News;

“FEAR and bewilderment has gripped families in Blackbird Leys following the revelation that the estate’s two towers are covered in cladding deemed a fire risk.
On Monday it emerged that samples sent by Oxford City Council to the Building Research Establishment had failed fire safety tests and will now be replaced.
It follows more than 12 months of refurbishment work on Windrush and Evenlode Towers as part on an ongoing £20m project to improve Oxford’s tower blocks, in which the cladding itself had cost £1.4m to install.”

However every cloud (of smoke) has a silver lining. Architectural cladding manufacturers have never had such a profitable year in prospect! Tens of millions of pounds worth of polyethylene core facades will have to be ripped off and replaced by fire resistant versions across the UK – BY THE SAME COMPANIES THAT SUPPLIED THE SUBSTANDARD MATERIAL IN THE FIRST PLACE.
Let’s hope that Oxford City Council ensures that the supplier responsible for this expensive disaster doesn’t get to profit from it for a second time.

 

“They deserve answers” – Theresa May.

“We have evidence that warnings were ignored and that these products continued to be used despite the warnings and that following the infections…[there was] a cover-up,”  – Andy Evans, chairman of campaign group Tainted Blood

Speaking to the BBC, Mrs May said: “They deserve answers, and the inquiry that I have announced today will give them those answers, so they will know why this happened, how it happened”

These quotations from today’s news refer not to the Deprox, but to the tragic suffering and loss of life from infected blood administered by the NHS in the 70s and 80s. At last, there is to be an inquiry, and the victims’ relatives will know how and why 2,400 NHS patients died.

Meanwhile a disturbingly similar tragedy is unfolding right here and now – and again the NHS turns a blind eye for fear of negligence lawsuits, and the corrupt medical suppliers hastily reap the profits before the mounting evidence of fraud and corruption forces them back to the dark places that spawned them.

The victims – the frail elderly, the cancer patients, the cystic fibrosis sufferers, have no idea that the C. difficile or MRSA infections they have suffered from were preventable. They are assured that the hospital rooms and equipment have been sterilised by the best technology available – the Deprox – which according to the Hygiene Solutions Ltd. website, “…achieves a log 6 reduction of even the most virulent of organisms.”

The truth is in stark contrast to this glib fabrication; – leaked emails and the testimony of former Hygiene Solutions employees prove that the Deprox units are turned up to their maximum output of  RH30 when tested, but in everyday use are turned down to output levels of RH 5 to RH 15 – with directly proportional reductions in H2O2 concentration and germicidal efficacy.

To compound this error, a recent letter published in the Journal of Hospital Infection revealed that most of the tested efficacy of the Deprox process could be attributed to the exceptionally high silver nitrate content of the Deproxin solution – an illegal additive which Hygiene Solutions now claims to have removed.

What residual efficacy remains absent this powerful cytotoxin remains untested and unproven.

The shocking and highly persuasive statistics from the UCLH hospitals, showing a substantial upwards step change in C. difficile rates corresponding exactly with the years of Deprox use, cannot be denied. These are public data sets, and the 75 or so extra infections over this period demand explanation.

We need an inquiry in to the Deprox scandal NOW, while lives can still be saved – not in 30 years time.

Fentiman backs off…

fentiman churchill

At the Regina Court this morning, F. William Johnson, QC., BA., LL.B., B.C.L. (OXON) representing Specialist Hygiene Solutions Ltd, preempted the proceedings by requesting an adjournment as instructed by his client.

I have no doubt whatever that the unprecedented response to yesterday’s deproxfraud.info post is the reason for this abrupt about-turn.

By the end of the day, that one article had received a staggering 595 hits, and this in spite of the USA being otherwise occupied. The top 5 countries of origin are listed below:

A heartfelt thank you to everyone who visited the site, and especially to those who spread the word via social media to achieve this resounding endorsement of the battle against corrupt medical equipment manufacturers.

UPDATE: INTENSE INTEREST IN DEPROX CASE

Since the news of Fentiman’s intended legal action was published, late on July 3rd, the blog posts have received an unprecedented 1349 views, 373 of which were from Australia and New Zealand. At the time of writing, 10.22am July 6th, today’s views are already at 190 and rising fast!

Fentiman seeks court order to gag Deprox whistleblower

regina_courthouse

Regina Courthouse

On Wednesday 5th July 2017, Hygiene Solutions Ltd. will attempt to register a gagging order against Richard Marsh, a former Deprox engineer, in an attempt to close down the highly embarrassing deproxfraud.info website.

The hearing will be before The Honourable Mr. Justice B.A. Barrington-Foote, who had already rejected a previous submission from Fentiman on the same lines. The case is at 9.00am, at the Regina Court of the Queen’s  Bench, 2425 Victoria Avenue, Regina, SK  S4P 4W6, Phone: (306) 787-5377.

The hearing is open to the public, and the documents filed in connection with the case may be examined and copied at the Registrar’s desk in the Courthouse.

It is of note that after 9 months and (as of this afternoon) 35,634 views of deproxfraud.info, Hygiene Solutions has finally attempted this legal action by way of an obscure legal instrument called a “Tomlin Order”.  If the shocking allegations made by deproxfraud.info are false, as Fentiman and Co. maintain, why wouldn’t they have sued for libel and defamation in September when the website was first published?

While the application is expected to fail, deproxfraud.info will continue publication regardless of the outcome.

UPDATE: RECORD DAILY HITS ON COURT CASE BLOG POST

This post has broken the record for daily hits. Since publication yesterday afternoon, this post has received 553 hits and still rising fast. The daily total is expected to top 600.

Deprox Cowboys!

Cowboys Deprox

Incredibly, so-called “Hygiene Solutions Ltd” whose Deprox and Ultra-V machines are wheeled in to intensive care units and operating theatres on a daily basis, operates from the back of a dirty farming and livestock supplies warehouse, belonging to D&H Animal Husbandry. Here the Deprox units of their “On-call decontamination service” are stored between call-outs alongside pails of cattle feed and assorted agricultural and veterinary detritus.aisle-g-1

Here is another view of the real Hygiene Solutions.  I have added some notes for the non-technical reader.aisle-g-2

  1. Deprox machines
  2. RangerLick Cattle Plus Mineral Buckets
  3. Deprox vent cap accessory
  4. Deprox vent cap accessory telescopic poles
  5. Stepladders for short Deprox operators
  6. Mix of crumpled polythene, brown paper and sticky tape
  7. Pallets of Deproxin.

The covert camera video below gives a good idea of the grubby reality behind Hygiene Solutions polished sales presentations:

These less than ideal surroundings are fertilised by a regular stream of D&H customers, arriving “fresh” from their chicken sheds, stables, pig barns and cow pastures, who trek malodorously  through “Hygiene Solutions Ltd” to the trade counter at the back of the barn.Deprox shit.PNG

Do you really want your ICU cleaned by cowboys?
