WiFi in the world of Electronic Medical Record

Surgeons and other doctors need to know know a bit about computers.  That stems from the electronic medical record growth surrounding us.  I’d say that it’s an important part of a surgeon’s knowledge base to know a bit about wireless internet connections, and internet connections speeds, and internet connection security – starting with wireless connection security.

Today, I just wanted to explore my own WiFi connection on my laptop.  I was comforted to know that my home WiFi connection is WPA-2 encrypted.  I was able to find out how that was done.  But I also saw that most of the hotels that I have traveled to were not protected in this fashion.  To me this means that I should be cautious surfing at hotels.

I was also curious about my speed.  I looked up my WiFi card in my computer by looking up the details of my wireless network connection.  It seems that I have a Broadcom 4313 card which is able to acces 802.11 b/g/n which can run at a speed of 72 Mbps.  These were data spit out on my Windows 7 equipped laptop.  At this time, I still haven’t figured out which Hz the transmission is traveling.  I’ve heard that it could be 2mHz or 5mHz – I think.

I decided to do a speed test on my connection with Charter.  With my WiFi equipped Laptop, I got speeds of 19.34 Mbps download and 3.32 Mbps upload. (ping was 24 ms).

Testing several more times:

  • Down/Up
  • 18.76/3.31
  • 19.01/3.31
  • 19.51/3.28

I’ll hopefully get a chance to test out these other numbers in other situations.

I have another computer which I just purchased a brand new wifi adapter to plug into the usb port.  It is the Linksys N900 AE3000.  I think Linksys and Cisco are somehow together.  It has 802.11a, 802.11b, 802.11g, 802.11n, Simultaneous 2.4 GHz and 5 GHz, runs on USB2.

Here are the testing on that computer.  I know the times are related to my signal strength and router.  But regardless here are some results.  Ping 32ms, Download speed 29.41 Mbps, Upload speed of 2.23 Mbps.  But the speed is somewhat erratic on this machine because it is located next to a chimney probably.

  • 31ms/21.59 down/2.79 up
  • 29ms/11.92 down/2.4 up
  • 32ms/38.83 down/3.09 up
  • 33ms/2.46 down/2.48 up
  • 34ms/23.41 down/2.68 up

Day 1 Vegas Cosmetic Surgery 2013

First official day of the Vegas Cosmetic Surgery and Aesthetic Dermatology Conference 2013

I particularly got a lot great ideas and info regarding Botox and Fillers (Juvederm).  I was very interested in the way they treated complications.

I also attended sessions that talked about social media, habits of very successful cosmetic practices, blogging, reviews, thank you notes, patient surveys, and the usage of YouTube videos.  I hope to act on much of this.  It was almost info overload.  And this was only day 1.

Plastic Surgery Related Booths we visited

  • Operative headlamp company – about $800 for a head lamp.  3 hour-4 hour battery life. LED bulb!
  • Zein Obagi.  Looked at the differences between Zein Obagi and Obagi
  • Touch MD – incredible stuff indeed.  Touch MD is a technological way to visually share the plastic surgical consultation with the patient.  There’s a program component which resides on the computer and then there’s a “cloud” component where the data resides.  The data can be accessed from many other devices and webpages via secure methods.  This is a great addition to EMR.  And perhaps would be a great addition to our plastic surgical practice in Modesto, CA.  They said that currently they don’t have any doctors in Modesto, CA who have Touch MD.  It also has a back end for picture management.

We were originally going to see a show, but instead we talked with the guys at Touch MD.

TiZO3 and Lip Balm

We found an an amazing Sun Screen for the lips.  It is made by the Fallene company in their Solar Protection Formula line.  TIZO is among one of their products.  Dr. Tammy Wu said that she has been looking for a lip balm that is a physical / mineral based for awhile.  We just found the LipTect product at the Vegas Cosmetic Surgery conference.  Along with this, we also found the  TiZO3 sunscreen for the face.  It has Titanium, Iron, and Zinc.  It is Paraben, Oil, PABA and fragrance free.  It is also tinted and is a very water resistant formula.  We will have the LipTect (Lip balm) and TiZO3 sunscreen available for purchase at Surgical Artistry, Modesto, CA.  Dr. Calvin Lee (me) takes credit for introducing Dr. Tammy Wu to the booth, and Dr. Wu made the decision to make an opening order!  One more reason for this – it would be an great product to protect a lip augmentation investment.

PrognoCIS EMR scheduling time mismatch solved

PrognoCis EMR shows that patients are one hour behind in the scheduler!

In the past, all I had to do for a problem like this was to make sure the zoom was at 100% setting rather than anything else.  The zoom feature is in the lower right corner of Internet Explorer.  But now it was different.

Windows Updated and Killed PrognoCis

Today, I came to work and found that my EMR had all the wrong times.   Patients on the schedule were shown to come in 1 hour earlier than they were supposed to.  So I always felt that patients were one hour late.

What happened was that my Windows 7 operating system had installed an automatic update that turned my IE9 (Internet Explorer) to IE10.

I’ll present my solution and the more elegant PrognoCIS solution

I reverted IE10 back to IE9, and told windows not to do any more updates.  

Note: this might be a bit drastic and unsafe for security reasons – there are options to choose for manually installing and choosing which updates you’d want – that’s more of a practical solution – I just picked the NO UPDATES choice as a dramatic chance to AUTOMATICALLY INSTALL UPDATES.

This indeed fixed the scheduler mis-match of times.  And I think this will prevent new installations until I want them.

We work hard to keep PrognoCis the way we want to with all the custom settings typed in and also we also surf the internet with Chrome to avoid messing up Internet Explorer – it’s a shame for Windows to just come in and destroy all that for our PrognoCis settings.  So this method works for me.

How to Revert IE10 back to IE9

  1. Start -> type in the box: “view installed updates” -> enter ->, find Internet Microsoft Explorer 10 -> right click on it and select uninstall
  2. Reboot computer

How to remove automatic updates

  1. Start -> type in the box: “windows update” -> enter -> click “change settings” -> select “Never check for updates (not recommended) or whatever level you want.


If you want something more elegant, for example – to use IE10, try the below instructions which I haven’t tried:

I wrote to PrognoCIS and they suggested a BETTER SOLUTION rather than my workaround:

By the way, PrognoCIS EMR wrote me back within 1.5 hours – this is very impressive!  And they sent me a PDF file with detailed instructions on how to do the following.

Hello Calvin,

Thank you for contacting tech support.

Please pull up the PrognoCIS site then go to Tools > Compatibility view settings >click on “Add” or add “” > Check the check mark of “Display all website in compatibility view” > click on “ok” button. After that please login to PrognoCIS and check it.

Also please zoom size of internet explorer, it should be 100%.

Hope this helps. Please let us know if you  have any query.

Here’s a screenshot of what they sent me as directions for Compatibility View in IE10

Additional Commentary from Calvin Lee regarding the tech support message

I wanted to add to others that you might have to press “ALT” to get the “tool” menu item to come up in the Internet Explorer.
