USA Today published an article today that tells a gruesome story. Most of us are washing our hands wrong. An internet is full of videos about proper hand washing techinque. So why are we still doing it wrong?
I filmed my 5-year-old daughter washing her hands and she does it pretty well for her age. Better than many adults. Take a look.
Hand washing in bullet points:
Wet your hands, close the tap
Apply enough soap
Rub your palms together to form foam
Spread the foam all over the hands and wrists – don’t forget the back of your hands, fingertips and thumbs
Keep rubbing for at least 20 seconds
Open the tap with your wrist or elbow (not your fingertips)
Rinse well with running water
Close the tap with your wrist, elbow or back of your hand. Or disposable towel if you are using them to dry your hands.
And remember, if you are in a public toilet, the door handle is the most contaminated surface there so try to open the door with something else than with your clean hands.
Like doctors and nurses in hospital, the dental professionals are more at risk of contracting viruses. Dental offices can also be a place where the viruses, such as corona can spread if the cross infection control is not up to the standards.
I have gathered the most important things here for dental professionals to check to make sure you are protecting yourself, the staff and the patients. I have not gone into things like instrument disinfection because that should be organised regardless the coronavirus. If in doubt, read this.
Use Soap
Something we should remember when using hand sanitiser is that it does not kill all the viruses like norovirus (the one causing the winter womiting disease). Therefore it is advisable (also advised by the World Health Organization, WHO) for all of us to wash hands 20 seconds with soap even though it is pain in the backside to wait for the hands to dry so that you can pull on the examination gloves. Remember to use disposable hand towels to dry your hands and close the tap either with your elbow or with the hand towel to prevent re-contamination of your hands from the tap.
Cover Up
In the normal situation where we treat healthy patients, a lower fluid resistance and filtration efficiency are acceptable (personally I use either ASTM Level 2 or Level 3 masks). But when we are at greater risk of treating a patient who might carry airborne diseases like coronavirus, TB and influenza, we should use masks that have the maximum filtration. These face masks you recognise from the markings FFP2.
It is even better if the face mask has a visor attached to the mask. But even if it has the visor, use also safety glasses/your normal glasses under the visor. If the face mask doesn’t have a visor, use safety glasses or separate visor – also on top of your normal glasses.
Now, I would use also disposable hats like they do when performing oral surgery because people (me too) have these mannerisms of touching our head, scratching our head etc. for example on a lunch break. And do we always notice we do that? If we don’t, then how do we know to wash our hands straight after before we take another bite from the sandwich.
Check Your Surface Disinfection Liquid
Today is the day to look deeper into the small print of your practice’s disinfection liquid. I did some research some time ago because I wanted to find out if the liquid we were using was killing everything it was meant to. I found out that not all of them kill for example norovirus. And if they don’t kill norovirus, I doubt that they kill coronavirus.
I cannot tell you which one to use, but the bottle should have all the information needed. If not, contact the supplier or the manufacturer. One thing I noticed when I did my research that the disinfection wipes and liquids for sensitive surfaces are the ones that do not kill viruses.
Wipe Wider
It is good idea to wipe the door and chair handles (the unit’s of course but also the regular chairs) with disinfection wipes. Also it is good idea to go through the other handles of the practice many times a day – even the ones outdoor.
Provide Hand Sanitiser for Patients
Place a bottle of hand sanitiser in the waiting room. I saw my physiotherapist yesterday and first thing I did was to wash my hands. Common people do not realise to do this so could you perhaps ask your patients to wash their hands (for 20 seconds) when they arrive to the surgery?
