Meaningful Use of Meaningless data - Lesson from the Teachers in Atlanta.

People are shocked by the story that teachers who are supposed to be setting good examples for school kids were involved in cheating.  The teachers were erasing incorrect answers on students standardized tests and entering the correct answers.
From CBS evening news:
 " It was to show phony progress at often troubled schools, what the report calls "the pressure to meet targets in the data-driven environment." Educator Diane Ravitch, author of "The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education," blames it on a federal law that links funding with test performance.
"We have a terrible federal law called No Child Left Behind that says that all schools have to have 100 percent of their students proficient in reading in math by the year 2014 or their schools will be shut down," Ravitch said.
From CNN
"I think the overall conclusion was that testing and results and targets being reached became more important than actual learning for children," (Gov. Nathan) Deal said. 
So is anyone surprised that this would happen?  When a single number becomes more important that the process, in high stakes situations, people will do what it takes to improve that target number rather than improve the process that the number is supposed to measure.  

Why is this an important lesson for Medicine?
1.  We have for long struggled with the USMLE scores as being a single number that is used to measure the quality of a medical student.  This is what is used as one of the most important criterion for selection to residency training programs.  This is in spite of there being no good data that scoring high on the USMLE equates to potential to be a good doctor.  Recently there was a an article in the leading journal on medical education highlighting this problem.  The USMLE has 3 steps.  Students who score well on Step 1 will postpone taking step 2 till they have finished interviewing for residency programs - just in case they get a lower score on step 2 and jeopardize their chances!  Many medical schools give students dedicated time to prepare for the USMLE.  So students who have been getting a curriculum that medical educators believe is appropriate to make them good doctors for 2 years take a couple weeks off to read for a test!  USMLE is a test of medical knowledge and it also tests whether a student can apply this to the clinical environment.  But it cannot measure a lot of other important competencies like communication skills, professionalism, ability to be lifelong learners etc.

2.  The recent mandate for Meaningful Use (HITECH Act) of EHR data has the risk of falling into the same trap.  While well-intentioned, it has several measures of very important clinical processes.  If done right, these processes have the potential of improving healthcare.  The problem is that these measures are linked to incentive payments from the Center for Medicare and Medicaid Services which make them high stake for doctors working on razor thin margins.  Doctors who fail to use EHRs meaningfully with their Medicare patients are at risk of penalties. Let us take an example:
One of the 25 measures of meaningful use is to show that doctors are doing reconciliation of medications (checking what patients are taking and where there are discrepancies, updating the medical record or educating the patient appropriately).  One popular EHR system has a system for putting a check mark against each medication as you confirm it or to delete it if the patient is not taking it.  Doctors and nurses go over this exercise with the patients and it can be extremely time consuming.  One would assume that after you have gone through the entire list of medications, you should have complied with the meaningful use requirement.  Unfortunately, after doing all this, to record in the database that you reviewed the medications, you have to click a button that marks that you reviewed the medications.  As doctors get pressured to see more patients in less time, guess what is going to happen?  Yes, they may be tempted to click that button whether or not they went through the process of reconciling the medications.  This is an example of how poorly designed software will lead to physicians targeting a number (% of office visits where reconciliation occurred) rather than do what is a critical part of a visit - making sure the patient is taking the right medication.  
The teachers in Atlanta has taught us a valuable lesson.  Even people who are expected to set examples of high moral values, when forced to meet requirements that are measured by numbers without actually getting the support they need to do their job right, will take shortcuts to make the numbers look better.  In today's data-driven society, this is a valuable lesson.

Google+ Circles Simplified

While Google Hangout is a unequivocal home run, Google+ Circles have a lot of people (including myself) scratching their heads.

After 2 days of using Google+ in the limited testing phase, it seems that we need 2 sets of circles:

  1. Circles to filter the feed (flood) of posts in Google Stream- this is mostly a convenience issue.  Depending on your mood and available time you can decide to see few, some, more or all the posts in your stream.  My guess is that I will create circles for this somewhat like this:
    1. Priority (Not sure of this yet) 
    2. Educational and Engaging, 2-way conversations - folks that I tend to learn from or interact online in a meaningful manner.
    3. One way but informative - folks that generally provide useful information in posts but we don't usually have conversations.
    4. Casual  
  2. Circles to share information with. - This is mostly targeting and privacy issue.  You want to post information that is meaningful to the viewer and you want to decrease the chances of it ending up with inappropriate audiences.  The privacy is not water-tight and thus with very sensitive information, you want to avoid posting online - use some other medium.  Some examples of using circles for this purpose are, sharing the place and time of an event with local friends, or wedding photographs with family, making colleagues aware of a journal article published by one of the doctors, reminding members of a professional organization to vote on a political issue etc.
    Why should we bother to do this?  Why not just post publicly and leave the filtering to the reader?  If you think about how the clinical decision support system became almost completely impotent due to alert fatigue, we would not ask this question.  As the amount of data in people's information (Google) Stream becomes overwhelming, it will be critical to do our part in reducing the noise:signal ratio.  It is just part of being good digital citizens.  
A point to note.
All your circle names appear on the left side of the Stream.  Right now Google does not allow rearranging these.  You can be creative by adding a Digit in front of the names you want to show up at the top.  Thus  "1 Engaging&Entertaining will appear near the top after the 4 default Google circles (Family, Acquaintances, Following and Friends).  You can of course rename these or delete these default circles and then they go away or get arranged in alphabetical order.

Google+ Early Impressions - Lots to Like - A Few Things to Tweak.

July 4th long weekend with a long list of to dos and fabulous sports on tap (Wimbledon, Womens' Soccer and India-WI test match) dissolved into a Google+ tire kicking session.  It all started when I woke up Saturday AM with an invitation from Pauline Sweetman via Anne Marie Cunningham.

The past 1 and 1/2 days I have been trying to understand the new Social side of Google keeping the education perspectives in mind.  A lot has been written about Google+ already.  So lets take a look at some of the key features of Google+ and what they are missing.


  1. The Stream - this is a very Facebook like UI.  The best part of this the ability to filter this stream by specific users.  You do this by creating circles of users and this list is visible on the left side of the page.  The other nice feature is that posts can be quite long allowing for a true conversation like experience.  The comments are not threaded so you cannot reply to a specific persons comment.  The last comment appears at the bottom of the conversation.  The conversation is protected from external viewers - it shows up only on the stream of people in the circle selected by the original poster.  There are several nuances and exceptions to this but as long as the folks in the circle adhere to certain rules, this conversation will be "private".  You can disable re-sharing of the posts but at the time of this writing, Google+ allows you to grab a link to a post and pasting this in a browser allows one to view the post even without logging into Google+!. Will this level of privacy be sufficient to overcome educators' and parents' resistance to getting school kids on Google+?
  2. Circles - Uniquely Google+ designed visual approach to organizing your contacts.  As long as the folks in the circle don't break the trust, the content of the conversations, photos etc will stay in the circle.  I think this set the bar very high for adopting Google+ to share any kind of sensitive information in a circle.  This is still much better than FB but users will probably leave all their sensitive information shareable only with immediate family or very close friends.  
  3. Hangout - This is probably the biggest home run of Google+.  The ability to do up to 10 user video conference at the drop of a hat is awesome.  You can "hangout" with your circle and any circle member who is around can drop in for a chat.  The other evening I joined Anne Marie's hangout session and we had the most interesting and educational conversation for over 90 min.  I know because Hangout asks you at 90 minutes if you are still there!  You can imagine using this with students and other learners.  Since Hangouts are not stored, the privacy is even better protected.  You can see a webcam feed of every one in the session.  The only part missing is a white board sharing feature which will be coming soon I guess (hope).
  4. Sparks - Users can select or create a feed of regularly updated data in their area of interest.  As they read this, they can share with their Google+ Stream.  Unfortunately it does not support Google Reader and it does not support RSS feeds.  I hope this gets fixed quickly.  Most users will want to decide what goes into their feeds rather than let Google+ decide this in the background.  I like to go through my stream of information from Journals, Blogs etc on Google Reader.  I like to tag, share with notes, and send to Facebook or Twitter.  Right now there is no way to do this with Google+.  The shared articles show up on Buzz but that is buried 3 clicks down from the Google Stream.  
Conclusions:  So there you are.  There are many good things about Google+.  Google has hundreds of millions of people who use its products on a daily basis.  It has had the opportunity to study other social networking apps and seen what the deficits are.  It has so many different apps like the Google Calendar, Google Groups, Google Reader and Blogger that are hugely successful.  Google must have a strategy of pulling these together seamlessly into Google+.  If not it will be a case of unfulfilled potential.  

A lot of information here may become irrelevant very quickly as Google+ gets feedback and makes changes based on its limited roll out and beta testing.  I hope it does.
