Should Alcohol-Based Handrub Use Be Customized to

Health-care Workers’ Hand Size?



• Objective: To evaluate the association between the volume of ABHR

taken by HCWs performing hand hygiene and the reduction of the

bacterial load in their hands, depending on their hands size.

• Design/setting: experimental, microbiological laboratory;

• Participants: 15 healthy HCWs with different hand sizes;

• Study protocol (EN 1500 standard):

Measurement of all health-care workers’ hand sizes;

Hand contamination with E. coli ATCC 10536;

Application of isopropanol 60%, from 0mL to 3mL, following the WHO

standard technique;

Fingertips culture.

Infect. Control Hosp. Epidemiol. 2016;37(2):219–221

• There is a direct association between the volume of alcohol-based

handrub taken by healthcare workers performing hand hygiene and the

reduction of the concentration of bacteria in their hands.

• The healthcare workers’ hand size significantly affects that

association.

• These results suggest the need of customizing the volume of alcohol-

based handrub used for hand hygiene, according to the size of the

healthcare workers' hands, for ensure appropriate hand antisepsis and

patient safety.


Should Alcohol-Based Handrub Use Be

Customized to Health-care Workers’ Hand Size?

Revisiting the WHO “How to handrub” standard

technique

ECCMID 2016, Amsterdam, submitted.

WHO fingertips first technique

WHO “How to handrub”:

standard technique x fingertips first

• Objective: To evaluate whether modifying the sequence of the WHO “How to

handrub” standard technique to clean the fingertips first would lead to a

greater bacterial load reduction in hands;





Application of 3mL of isopropanol 60%, for 30 seconds, on a random order,

once using the WHO standard technique and once using the WHO fingertips-

first technique;

Fingertips culture.

In conclusion, WHO fingertips-first technique proved to be significantly more

efficient in cleaning hands than the WHO standard technique.



What about the duration of handrubbing?

Duration of handrubbing


• Objective: To evaluate the association between the duration of handrubbing by

HCWs and the reduction of the bacterial load in their hands;





Application of 3mL of isopropanol 60% following the WHO standard

technique, each one with a different duration of handrubbing, from 10 to 60

seconds;

Fingertips culture.

But after all, what is the minimum bacterial reduction to be

accomplished with the hand hygiene procedure to avoid

bacterial transmission?

The transmission study

Presented as an oral session in the ASM - Microbe 2016


• Objective: To evaluate what is the minimum bacterial load in hands to efficiently

accomplish cross transmission skin-to-skin;


• Participants: 6 healthy HCWs with different hand sizes (2 in each category of

small, medium and large);

• Study protocol:

Hand contamination with E. coli ATCC 10536, in growing concentrations;

Hand holding with another HCW whose hands are clean, for 1 minute;

Fingertips culture of both.



• The idea was to evaluate what was the minimum bacterial load in

hands to accomplish cross-transmission skin-to-skin (1 log10);

• Then to compare that number with the average contamination

burden on HCWs hands in clinical practice (± 1-3 log10);

• Then, realize what is the minimum bacterial reduction (2 log10) to be

accomplished with the hand hygiene procedure to avoid bacterial

transmission (“microbiological concept of safe hands”).

• Then, suggest the revision of the norms EN 1500 and ASTM E2755-10.


Impact of using a device providing individual feedback on health-care

workers hand hygiene behavior: a cluster-randomized clinical trial

On going study, funded by the Swiss National Research Foundation

It could be you in this bed...

...so, give the patients the same care you would like to have, perform hand hygiene before touching them!

Em síntese...

• A higienização das mãos ainda é a medida mais simples, segura e efetiva para

a prevenção de todas as infecções hospitalares;

• Enquanto a adesão à higienização das mãos têm aumentado, a qualidade do

gesto ainda têm muito a melhorar;

• Para uma adequada descontaminação de suas mãos:

Use 2-4 mL de solução alcóolica de acordo com o tamanho da sua mão

Friccione todas as partes de suas mãos, mas, sobretudo, não se esqueça das

pontas dos dedos

Friccione suas mãos por pelo menos 15 segundos

Em cada um dos 5 momentos, como você gostaria que fosse feito com você!

Proteja seus pacientes como a quem você quer bem... Use álcool gel antes de tocá-los!
