prying eyes and nosey fingers with a few

computer screen or gain access to the EMR

Setting up a screen lock (Super + L)
On a Windows workstation hold down the
Windows Key (Super Key) and touch the L key at
the same time. Be sure not to let go of the Super
key before you touch L – otherwise you will log
yourself out instead of locking the screen
PS: This will only work if you've already set up a
password

On an Ubuntu workstation the default hotkey
shortcut for the screen lock is:
CTRL + Alt + L
You can customize this
by going to your top panel and opening:

First make sure the Lock Screen icon is the leftmost of your Apple-provided
menubar icons. Hold down the Command key and drag the lock icon to the
left edge of your existing icons, then drop the icon. This step is necessary to
make this trick work.
Now open System Preferences, and click on the Keyboard & Mouse pane.
Click the Keyboard Shortcuts tab, and then click the plus sign to add a
shortcut.
Leave the pop-up menu set to All Applications, enter Lock Screen for the
Menu Title, and then define a keyboard shortcut to use:

File “Shredding”:
Did you know that deleting a file in Win/Mac/Linux leaves traces of it behind on your hard-drive?
The "delete" operation in Windows and other operating systems only removes bits of
information from files so they just appear deleted in OS. They are actually till there, on your
hard-drive, but they have just been dis-associated from the file table. It is easy to retrieve those
files using widely available specialized file recovery software.
You do not want to leave traces of sensitive identifiable patient information lying around on your
network workstation hard drives!
The one and only place where patient files should permanently reside is on your secure and
fully backed up OSCAR EMR server.
In order to remove, or “shred” files permanently from all your office workstation computers you
have to use a program that is capable of rewriting the files with random series of binary data
multiple times. This process is often called shredding. That way, the actual content of the file
has been overwritten and the possibilities to recover such a shredded file are mostly theoretical.

File “Shredding”:
For Windows and Ubuntu
a good Open Source file shredding program is:
BleachBit

Keeping your Workstations Safe
With a few simple steps you can protect your patients' privacy in the
medical office.
It is also important to rotate passwords regularly. Use strong passwords:
ie 6 to 8 characters, mix of cases, mix of alpha, numbers and special
characters, eg: @bcD!234
Be sure to maintain good security habits in the office. Never leave an
unattended workstation unprotected.
