Page Background


An ongoing research project addresses people in

hospitals responsible for services on built environments. The aim of

this project is to systematically uncover the present situation of


prevention in water systems in selected health care (HC)

organisations in different countries. The project contributes to

working out a

reference system

guiding people responsible to

identify, understand and properly take action for prevention.


The stakeholder theory provides a suitable theoretical

framework to analyse the relation between policy issues, responsibil-

ities and activities of people participating in processes serving water

systems to contribute to prevention and hygiene. The theoretical drive

of this research is inductive, based on a qualitative approach of data

collection, divided into two consecutive phases.


Preliminary results exemplarily present the organisational

structure, legislative frames regarding water safety and


prevention, types water systems and related services and processes,

seen from the FM/FS perspective with a technical focus.

Discussion and/or Conclusion(s):

Each hospital representing a case

study will work out further endeavour on managing risks properly

according to organisation

s specific necessities.

Hand-held device decontamination within healthcare

College London Hospitals


The use of mobile phones and tablet computers has

become widespread in the clinical environment. These hand-held

devices may be contaminated with microorganisms and become a

potential reservoir for cross-transmission of pathogens between

healthcare workers and patients.


To determine the efficacy of the Codonics


UV-C disinfection technology to decontaminate hand-held

mobile devices used in a hospital setting.



was introduced on two wards. Tablets were not

disinfected on the control ward. After 2 months of use a cross-over was

performed with a washout of one week.

Surface sampling using blood contact plates (25 cm


) were taken from

the tablet screen before and after disinfection and also from the tablet

case (pre-disinfection only).


The median aerobic colony counts (ACC) on tablets sampled

on test and control wards was 8 [interquartile range (IQR) 4

14] cfu/

25 cm


and 12.5 (IQR 5

30.5) cfu/25 cm


respectively (n = 102).

After UV disinfection the contamination reduced to 0 cfu/25 cm



80% of tablets, median ACC was 0 (IQR 0

0) cfu/25 cm



The median ACC on cases sampled on test and control wards was

37.5 [IQR 21.3

59] cfu/25 cm


and 78.5 (IQR 38.3

146) cfu/25 cm



Discussion and/or Conclusion(s):


effectively reduced

contamination on tablets used in healthcare environment, but not

all protective cases could be decontaminated by this method.

There is no generally accepted guidance how to reduce contamination

on mobile devices in healthcare settings hence there is an obvious

demand for novel approaches to ensure patient-safety and minimize

risks posed by contaminated computers and mobile phones in clinical

Hand scanners

are they a risk?

Many hospital staff are obliged to use hand scanners to

monitor their entry and exit into the workplace. We hypothesized that

such scanners may provide an additional reservoir of pathogenic and

antibiotic-resistant bacteria that may predispose to cross contamin-

ation between staff.


A microbiological evaluation was conducted to

assess hand scanner contamination, with door handles commonly

used by staff sampled for comparison.


The study had two stages:

Stage 1

Six of the most commonly used scanners situated at the

entrances to our hospital and door handles/push plates of the main

male and female changing rooms were swabbed twice a day for 8 days.

Stage 2

four hand scanners and four changing room door handles

nearer clinical areas were swabbed twice a day for 8 days.

A total of 160 samples were taken and the samples cultured for

Staphylococcus aureus

(MSSA and MRSA),

C. difficile

and faecal

organisms (Enterobacteriaceae and enterococci).


Target bacteria were recovered from 13.8% of samples and

included MRSA (


= 1), MSSA (


= 18) and faecal bacteria (


= 3).

Discussion and/or Conclusion(s):

Staphylococcus aureus

were recov-

ered from hand scanners and door handles that are commonly used by

staff despite the fact that hand scanners are cleaned twice a day. There

was no statistical difference in the results from hand scanners versus

frequently used staff door handles. Effective hand hygiene practices to

prevent contamination of hand scanners needs to be re-enforced to

minimize the risk of spread of pathogenic and antibiotic-resistant

MRSA and ultrasound

How does Isle of Man compare?

Nobles Hospital


With radiology playing an increasing role in diagnosis,

Ultrasound (US) offers a relatively safe, radiation free method of

diagnosing multiple conditions. It also poses a higher risk of pathogen

transfer between patients, through the ultrasound equipment.


To assess for

Staphylococcus aureus

and methi-

cillin resistant

Staphylococcus aureus

found on US machines in Nobles

Hospital, Isle of Man.


We identified a total of 8 machines in the hospital. One in

each of the emergency department, intensive care unit, coronary care

unit, acute medical assessment unit and the gynecology department,

with a further three in the radiology department. With swabs obtained

from the microbiology department, we swabbed each machine in at

least 7 different key areas looking for

Staphylococcus aureus


methicillin resistant

Staphylococcus aureus

. These included the key-

boards, control buttons, US machine screens, US probes, gel bottles

and gel bottle holders. All samples were collected on the same



Of the 50+ samples obtained and analysed, none grew either

of the tested organisms.

Discussion and/or Conclusion(s):

The results from this study are

overwhelmingly positive indicating health care workers at Nobles

Hospital are prudent with infection control procedures. This can only

be beneficial for patient care. This is in contrast to studies undertaken

in both the UK and France, though these studies were over a longer

time period. We plan to repeat pan cultures over a longer period to

better understand the proficiency of infection control procedures in

Nobles hospital, however these results are encouraging.
