I didn't realize that I had to manually page through the slides at the top to understand the product. I scrolled down and had no idea what the product was. Might want to put that first instead of hidden on slide 4.

I still haven't figured it out (partially for lack of trying, I'll admit). Kind of reminds me of Donald Norman's criticism of doors that require a user manual, even if it's only one word.

Earlier quoted context omitted.

Can you provide references? That may be true of your basic drugstore Purell, which just contains ethyl alcohol. But the literature does indicate that hospital-grade hand sanitizers (a blend of alcohols, and/or a non-alcohol equivalent) are far superior and immediately effective against most organisms. See for example, http://cmr.asm.org/content/17/4/863.short

Hand washing should be done with runnin water and soap when possible. If you don't hav running water and soap you cannise handgels, but they don't kill everything. Alcoholgels don't kill c.diff. Alcohol gels only work on hands that are clean. You need to be careful with the soap you chose because hands can be "too clean" - some soaps are harsh on the skin and cause conditions suitable for bugs. http://www.nhs.uk/Cond…

Yeah this is correct for Noroviruses as well - good old soap and water is the most effective against Norovirus, more so than alcohol and disinfectant gels.

My wife works as a paediatric doctor in the NHS, and has told me that the regular use of alcohol gels leaves a slimy residue after 2 or 3 uses, prompting her to properly wash her hands (as well as wearing new gloves for every patient, obviously).

The handles on inward opening doors are a vector for bacteria because there is no way of physically interacting with them without using your hands and touching the same place as everyone else. This product does not solve this problem, but instead tries to insert itself into the users' task flow at precisely the time when their goals are focused elsewhere (on opening the door).

I agree wholeheartedly.

> This is a rude interruption and will likely annoy rather than encourage more sanitization. In the video (0:59), a woman sanitizes her hands then must immediately compromise them again to actually open the door.

The idea is that you open the door with one hand and dispense sanitizer into your other hand simultaneously and then sanitize the other hand after passing through.

I've seen things along this line in restaurants before:

Slightly related: I wish door handles, taps, bathroom flushes, up/down lift buttons etc. are mostly foot operated everywhere. There's really not much advantage of interacting with all these knobs with your hands.

I'm having a hard time remembering what it was but around this time last year I saw someone demonstrating a sort of gel like cover (similar to this http://www.amazon.com/Cyber-Clean-25055-Office-Pop-up/dp/B00...) at a startup weekend.

The idea was to cover door handles with it in hospitals etc and had received positive feedback from quite a few local hospitals if I'm remembering correctly. I'm not sure what happened to that project though. I like that solution much better than this though.

I also think that these kind of gels give a false sense of security, I have anywhere up to four different carers coming through this house on any given day using the stuff. And they do something that might be slightly medical in nature, then it's a quick squirt of the gel and hey presto no more tiny stinky biting things! But that is absolutely NOT how they work, these gels are generally designed to be used AFTER wash…

See for example, http://cmr.asm.org/content/17/4/863.short

No problem, from the CDC[0] report entitled "Guideline for Hand Hygiene in Health-Care Settings"[1] From that reference it says, we have:

"Alcohols are not appropriate for use when hands are visibly dirty or contaminated with proteinaceous materials." "Alcohols are rapidly germicidal when applied to the skin, but they have no appreciable persistent (i.e., residual) activity." "Despite its effectiveness against these organisms, alcohols have very poor activity against bacterial spores, protozoan oocysts, and certain nonenveloped (nonlipophilic) viruses. Similarly, certain accepted methods for evaluating waterless antiseptic agents for use as antiseptic hand rubs require that 3 mL of alcohol be rubbed into the hands for 30 seconds, followed by a repeat application for the same duration. This type of protocol also does not reflect actual usage patterns among HCWs."

The alcohol gels are good, but I think they're not a cureall was my point.

Just from - terrible - experience, C. Diff is one bug which is certainly not sanitized by any sort of alcohol-based sanitizer. Spreading C. Diff throughout a hospital population (even one floor) is pretty devastating and dangerous.

Is there any empirical research showing that placing sanitizer in door handles (as opposed to next to the door, or in the hallway, or wherever- - most hospitals have sanitizer everywhere) has an increase in use - especially for caregivers?

Unsure. In the hospitals I've worked at, there are sanitizing stations mounted either directly outside of any n-set of rooms (in ER's, they're mounted outside every room). It's habit for any health personnel to sanitize on the way in, rub a bit, wash hands at sink, and sanitize on the way out. In some cases (should theoretically be all...but hey, we're lazy) we wash on the way out as well.

>but I think they're not a cureall was my point.

I honestly don't know a single nurse / medical staff or even IT person in a hospital or university that thinks they are, though. You might not be giving people enough credit. Anecdotal, yes, but I've never seen people think of them as a "cureall" or even as a replacement of washing hands. It is always in addition or inbetween things where you can't get to a handwashing immediately (e.g., candidates shaking hands)shrug
