We had a lot of fun putting together this week’s list. Enjoy!
A Spreadsheet Way of Knowledge by Steven Levy. A few weeks ago we noted that it was the 35th anniversary of the digital spreadsheet. Steven Levy noticed too and dug up this piece he wrote for Harpers in 1984. If you read nothing else today, read this. First, because we should know where our tools come from, their history and inventors. And second, but not last nor least, because it has wonderful quotes like this:
“The spreadsheet is a tool, and it is also a world view — reality by the numbers.”
The Ethics of Experimenting on Yourself by Amy Dockser Markus. With new companies cropping up to help individuals collect and share their personal data there has been an increased interest in citizen science. A short piece here at the Wall Street Journal lays the groundwork for what may become a contentious debate between the old vanguards of the scientific institution and the companies and citizens pushing the envelope. (The article is behind a paywall, but we’ve archived it here.)
Better All The Time by James Surowiecki. I started reading this thinking it would be another good piece about the digitization of sport performance and training, and it was, but only partly. What begins with sports turns into a fascinating look at how we are succeeding, and in some cases failing, to improve.
Article 29 Data Protection Working Party: Opinion 8/2014 on the Recent Developments on the Internet of Things. Do not let the obscure boring title fool you, this is an important document, especially if you’re interested in personal data, data privacy, and data protection rights. Most interesting to me was the summary of six challenges facing IoT data privacy and protection. I’m also left wondering if other countries may follow the precedents possibly set by this EU Working Party.
30 Little-Known Features of the Health and Fitness Apps You Use Every Day by Ash Read / AddApp. Our friends at AddApp.io put together a great list of neat things you may or may not know you can do with various health and fitness apps.
Man Uses Twitter to Augment his Damaged Memory by John Paul Tiltow. Wonderful piece here about Thomas Dixon, who uses Twitter to help document his life after suffering a traumatic brain injury that severely diminished his episodic memory. What makes it more interesting is that it’s not just a journal, but also a source of inspiration for personal data analysis:
”Sometimes if I have like an hour, I’ll be like ‘How’s the last week been?’“ Dixon says. ”I’ll look at the past week and I’ll go, ‘Oh, okay. I really do want to get a run in.’ So I will use it to influence certain decisions.”
Patients and Data – Changing roles and relationships by David Gilbert and Mark Doughty. Another nice article about the ever-changing landscape that is the patient/provide/insurer ecosystem.
The Quantified Anatomy of a Paper by Mohammed AlQuaraishi. Mohammed is a Systems Biology Fellow at Harvard Medical School, and he’s an avid self-tracker. In this post he lays out what he’s learned through tracking the life of a successful project, a journal publication (read it here), and how he’s applying what he learned to another project.
Calories In, Calories Out by (author unknown). A fascinating post about modeling weight reduction over time and testing to see if said model actually matches up with recorded weight. Not all math and formulas here though,
“I learned several interesting things from this experiment. I learned that it is really hard to accurately measure calories consumed, even if you are trying. (Look at the box and think about this the next time you pour a bowl of cereal, for example.) I learned that a chicken thigh loses over 40% of its weight from grilling. And I learned that, somewhat sadly, mathematical curiosity can be an even greater motivation than self-interest in personal health.”
Fitness Tracker on a Cat – Java’s Story by Pearce H. Delphin. A delightful post here about tracking and learning about a cat’s behavior by making it wear at Fitbit. Who said QS has to be serious all the time?!
100 Days of Quantified Self by Matt Yancey. Matt downloaded his Fitbit Flex data using our data export how-to then set out analyzing and visualizing the data. Make sure to click through for the full visualization.
IAMI by Ligoranoreese. If you’re in San Francisco consider stoping by the Catherine Clark Gallery for this interesting exhibit. The duo, Ligoranoreese, created woven fiber optic artwork based on Fitbit data.

Anyone have a good way to aggregate and visualize data?

Memory, cognition, and learning are of high interest here at QS Labs. Ever since Gary Wolf published his seminal piece on SuperMemo, and it’s founder Piotr Wozniak, in 2008, we’ve been delighted to see how people are using space repetition software. Our friend and colleague, Steven Jonas, has been using SuperMemo since he read Gary’s article and slowly transition to daily use in 2010. Steven has been quite active in sharing how he’s used it to track his different memorization and learning projects with his local Portland QS meeup group. At the 2014 Quantified Self Europe Conference, Steven introduced a new project he’s working on, memorizing his daybook – a daily log he keeps of interesting things that happened during the day. Watch his fascinating talk below to hear him explain how he’s attempting to recall every day of this life. If you’re interested in learning more about spaced repetition we suggest this excellent primer by Gary.
You can also download the slides here.
What did you do?
I used a spaced repetition system to help me remember when an entry in my daybook occurred.
How did you do it?
Using Supermemo, I created a flashcard each morning. On the question side, I typed what I did the previous day. On the answer side, I typed down the date. SuperMemo would then schedule the review of these cards. I also played around with adding pictures and short videos from that day to the card, as well.
What did you learn?
First, that this seems to work. I’ve built up a mental map of my experiences, unlike anything I’ve ever experienced. I also learned that I hardly ever remember the actual date for a card. Instead, it’s a logic puzzle, where I can recall certain details such as, “It was on a Saturday, and it was in October, the week before Halloween. And Halloween was on a Thursday that year.” From there, I can deduce the most likely day that it occurred. I’m also learning which details are most helpful for placing a memory. Experiences involving other people and different places are very memorable. Noting that I started doing something, like “I started tracking my weight”, are not memorable.
Today’s post comes to us from Steven Jonas who led the Spaced Repetition breakout session at the 2014 Quantified Self Europe Conference. Spaced repetition is a common topic in the Quantified Self community and we’ve seen great examples from Jeopardy champion Roger Craig and Steven. In this breakout session, conference attendees discussed reasons for using spaced repetition, past experiences, and potential pitfalls. You’re invited to read the description of the session and then join the discussion on the QS Forum.
By Steven Jonas
The Spaced Repetition breakout was a knowledge sharing session around the use of spaced repetition tools, such as SuperMemo, Anki, and Memrise. There were two major themes during the discussion: what can spaced repetition be used for, and what is the value of it?
Many people use Spaced Repetition to memorize vocabulary while learning a foreign language. But it has other uses also. Novel uses of spaced repetition include: remembering the faces of authors of books and articles and memorizing entries from one’s own datebook to construct a mental timeline . We explored other possible uses of this powerful tool, such as remembering facts about people, or using it to keep in mind projects that one would like to do.
Why memorize information when most facts are just a web search away? We discussed a few reasons to commit facts to memory. One is that most breakthroughs come from connecting ideas together. So, by retaining what one has already learned, it makes it easier to make connections with new ideas as they are encountered.
Also, spaced repetition can be used to change your overall relationship with a subject of knowledge. One person told of how he tried to multiple times to learn Spanish with poor results. His conclusion was that he just wasn’t good at learning languages. After using spaced repetition to build his vocabulary, he changed his self-assessment. It wasn’t that he was bad at languages, he just needed a better process. Or consider the experience of memorizing poetry. Holding a poem in memory changes one’s relationship to it. Adding a poem to one’s repertoire creates a sense of ownership over the poem.
We acknowledged in our discussion that spaced repetition practice is fragile, because for it to be most effective it must be done every day. A neglected spaced repetition system leads to an overwhelming number of cards to be reviewed, which can lead to abandoning the practice altogether. This is a problem that, so far, does not seem to have a good solution.
If you’re interested in keeping this conversation going about what should happen to our data after we’re gone you’re invited to join the discussion on the QS Forum.
Our QS Conferences are organized to maximize discovery and serendipity. The entire program results from us inviting attendees to present and participate. You’re never quite sure what you’ll get, but it’s hardly ever boring! I didn’t know what to expect when Caspar Addyman took the stage in Amsterdam to talk about “Tracking your brain on booze”, but he very quickly grabbed my attention. His talk reminded me that, as Malcolm Gladwell once reported, “How much people drink may matter less than how they drink it.”
Q: How do you describe Boozerlyzer? What is it?
Addyman: The Boozerlyzer is a drinks-tracking app for Android phones. It lets you count your drinks and their calories and tells you your current blood alcohol. Crucially, it also lets you record your mood and play a range of simple games that measure your coordination, reaction time, memory and judgment.
What Boozerlyzer explicitly does not do is tell people how much to drink. We think people would find it patronizing and off-putting. Rather we hope that it will help people get better insight into how drinking affects them.
In addition, if users agree, their data is sent to our servers to contribute to our research on how drink affects people. I’m a researcher with the Center for Brain and Cognitive Development, Birkbeck College, University of London, and this project was started as a way to collect data beyond the artificial setting of a laboratory.
Addyman: I originally had the idea back in 2003 while doing my undergraduate psychology degree. I was interested in how to study the affects of recreational drugs. The web technology of the time couldn’t be used when people were out at the pub or club so I didn’t pursue it.
In summer of 2010 I took part in a science & technology hack day in London and the idea occurred to me again, this time using smartphones. So I told a few friends about it. Mark Carrigan, a sociologist at Warwick University, opened my eyes to the more sociological types of data that we could gather. This broadened the aims from my initial very cognitive focus to think about the emotional and social experiences involved with drugs and alcohol. That was at the end of 2010. All that remained then was to invent the app. I’m not really a developer and have been working on this in my spare time so it has taken longer than I’d expected.
Q: What impact has it had? What have you heard from users?
Addyman: I have been using the app myself for 6 months now and the thing that has surprised me the most is how rapidly the drinks accumulate if I’m out with friends. A few drinks early in an evening, then a couple of glasses of wine with a meal and then more drinks all through the night. Over a particularly sociable weekend I find myself drinking a disturbing amount even though it doesn’t seem that way at the time.
We started our first public beta in December 2011 and have a hundred or so users. I still have to analyse the first batch of data and usage statistics. But, a first look at the data from December and January showed something surprising: the Christmas season seems to ratchet up drinking levels, normalising heavy drinking on into January. Unfortunately, I don’t think I’ve got enough data to tell if this is real trend.
In terms of direct feedback from users, generally, we’ve had positive reaction to the idea but there are plenty of things we can improve. One of the biggest problems with the enterprise is that our users forget to actually use the app when in the bar, or when they’ve stopped drinking. Also, people are willing to track their drinks and their mood as they go along, as that takes very little time. But at the moment the games take a little too long to play, and the game feedback is a bit too abstract. We aren’t yet giving estimates of drunkeness based on game performance. Here we are in a bit of Catch 22: more compelling feedback ought to be possible once we’ve got a reasonable base set of group data to run some regression analysis but without interesting feedback we have trouble getting people to play the game in the first place.
Q: What makes it different, sets it apart?
Addyman: One big difference between our app and many tools in the personal health world is that our focus is not on behavior change, but instead on data for scientific research and self-learning.
Also, this is an academic, non-commercial project. Our app will always be free. We will never collected any data that could directly identify you nor will we sell any of the data we collect. We believe in open systems, open data and open minds. The code we write is open sourced. The data we collect will be available to anyone that wants to study it.
Q: What are you doing next? How do you see Boozerlyzer evolving?
Addyman: The Boozerlyzer is our first app and there are still plenty of improvements to make to it. But, in addition, we want to broaden our scope and apply the same principle to recreational drugs and the effects of various medications.
As an example, I met Sara Riggare Sara Riggare from the Parkinson’s Movement at the Amsterdam QS conference. She pointed out that a version of Boozerlyzer could help Parkinson’s patients track their medication intake and quantify the effects of the medications on mood, coordination, memory, etc. We are starting a collaboration to redesign the app for this purpose.
Meanwhile, my own motivation for starting this project was always to be able to do better research into recreational drugs. This has never been a more pressing concern, and I am hoping that a drugs tracker app can help. Obviously, this is fraught with legal and ethical difficulties so we are having to tread carefully. See here and here for more background on this.
Q: Anything else you’d like to say?
Addyman: We have already benefited greatly from our contact with QS community. The conference was a great inspiration and I wish could get to more of the lively London meet ups. If anyone out there would like to get involved with our project, we’d love to hear from you. Any advice or experience you could lend us would be greatly appreciated. Our project is both open source and open science. We believe in the power of collaboration and so would love to hear from anyone with similar projects in mind.
This is the 12th post in the “Toolmaker Talks” series. The QS blog features intrepid self-quantifiers and their stories: what did they do? how did they do it? and what have they learned? In Toolmaker Talks we hear from QS enablers, those observing this QS activity and developing self-quantifying tools: what needs have they observed? what tools have they developed in response? and what have they learned from users’ experiences? If you are a “toolmaker” and want to participate in this series, contact Rajiv Mehta at firstname.lastname@example.org.
This is the eight post in the “Toolmaker Talks” series. The QS blog features intrepid self-quantifiers and their stories: what did they do? how did they do it? and what have they learned? In Toolmaker Talks we hear from QS enablers, those observing this QS activity and developing self-quantifying tools: what needs have they observed? what tools have they developed in response? and what have they learned from users’ experiences?
For me, some of the most interesting QS talks have been by those creatively repurposing existing sensor technologies for novel self-tracking applications — such as Mikolaj Habryn’s Noisebridge, at an early QS meetup, and Hind Hobeika’s ButterflEye goggles, at the QS Amsterdam conference. It’s fascinating to hear what the inventors are thinking long before their product is in the market. Here, Eric Gradman, master hardware hacker, tells how he is applying his skills to a focused life-logging application.
Q: How do you describe Facelogger? What is it?
Gradman: The Facelogger is a passive lifelogger that helps me remember every person I meet by creating flashcards of their face, name, where we met, and our conversation. Facelogger consists of an always-on videocamera necklace, a software suite to process the video, and a smartphone interface for reviewing the flashcards.
The camera is a commercially available Looxcie camera, which was modified with a prism so it hangs around the neck. This camera continuously captures activity, and has a button that allows you to save the preceding 30 seconds of footage (footage that’s not saved is automatically discarded). When I meet someone for the first time and they introduce themselves, I press the button. The camera preserves the previous 30 seconds of footage which hopefully includes a good video frame of the person, their name, and what they said about themselves.
When I next plug the camera into the computer, all the captured video clips are automatically uploaded to a server, and sent to Amazon Mechanical Turk. There, human beings identify the most representative faces from the video, determine their names, and even transcribe the conversation.
Facelogger gathers all the information and creates a Facecard, which can be reviewed later on a smartphone. A Facecard is like a flashcard, but it shows someone’s smiling face, their name, a map of where you met, a link to the video of the conversation, and often even a transcript of the introduction. I can search the text of the Facecards, sort them chronologically, or by geographic proximity.
Q: What’s the back story? What led to it?
Gradman: Like any self-respecting geek, I’ve always tried to stay a technological step ahead of my peers and a technological leap ahead of my parents. But when I discovered that my parents use the same model smartphone I do, I realized I was beginning to lose my edge. To me, the next frontier for personal electronics is wearable technology, and the natural application is self quantification.
But what to quantify? As a hardware hacker and artist, my first foray into QS wearable technology was definitely more for entertainment purposes. Called the Narcisystem, it was a biosensor suit featuring sensors for pulse, heading, EEG, pedometry, and breath alcohol level. I used the output of these sensors to drive the lights, sounds, and ambiance at a party venue. Fun, but not really a form of human augmentation.
I have terrible trouble remembering the names and faces of people I meet. Its hard to say which is worse: my face-blindness or my memory for names. I’ll meet someone, shake their hand, and we’ll introduce ourselves. Moments later I realize with panic that I’ve already forgotten their name! And hours later, if they’ve changed clothes, altered their hair, or removed their glasses, I’ll blithely reintroduce myself like we’ve never met. At least I’m not shy!
I’ve always wanted to offload the mental burden of remembering people. When I was in school and I needed to remember something I used flashcards. Why couldn’t that technique work for people too?
Q: What impact has it had? What reactions have you had?
Gradman: Because the Facelogger is a first-stage prototype I am its only user. Has it helped me remember people I meet? You bet it has. I’m amazed by the quality of the Facecards and by how effective they are at jogging my memory. I get the general sense that reviewing Facecards a day or two after meeting someone gives me an opportunity to properly commit someone’s name and face to memory at my own pace … something I simply cannot do “on the fly” as we meet.
There’s another purely psychological effect: because I’m confident that my technology is taking care of remembering for me, I can relax into the conversation. I was never shy about saying “hi” to people before, but I did experience stress over the fact that I immediately forgot their name and face. Now with that interaction captured and searchable, I’m not bothered at all.
I’m sensitive to the ethical concerns with capturing someone on video without their consent. When asked what I’m wearing around my neck—and as you might expect, that happens a lot—I never lie. I explain that I’m wearing a video camera to help me remember people I meet. Invariably, I’m asked “is it recording me now?” I’ve been asked to turn it off, and I always comply. But a surprising number of people tell me they want their own Facelogger. It turns out there’s demand for a device to help remember people’s faces and names!
Some have questioned the legality of wearing a video camera. But there are already cameras trained on us wherever we go. You can buy a video camera hidden in a pen, or a pair of sunglasses. Will our social mores (or our laws) surrounding cameras trail so far behind the technology?
Very few have actually questioned the morality of wearing a video camera. In the age of pervasive social networking we’re living highly examined lives. For anyone with a camera on their mobile phone, its not such a stretch to imagine wearing the camera around their neck.
Also, I’m careful to remove the Facelogger when I’m not likely to meet new people:at home, in a business meeting, etc. I do this because the purpose of this device is not to have a record of every conversation I have.
Q: What makes it different, sets it apart?
Gradman: Life-logging is always something that fascinated me, but I felt that an ever growing cache of unsearchable video of my life would just be a huge burden. Facelogger is an experiment in constrained lifelogging. By only capturing moments that share a particular characteristic and have common features Facelogger allows for a well-defined process of data extraction and collation that address a specific shortcoming.
Gordon Bell, the pioneer of life-logging described his always-on MyLifeBits image recorder as “write-once, read-never.” For me, the decline in storage costs is not sufficient reason to record my entire life on video. Huge amounts of unprocessed video is just video I’ll have to review someday! That’s why I find it so easy to resist the temptation to press the “capture button” more often. Unless I have automatic tools to convert video into a compact searchable representation—in this case, a Facecard representing a person I’ve met—the video just isn’t worth saving.
There are other tools out there designed to help remember names and faces. Evernote recently released Hello, a mobile app to record people. What distinguishes Facelogger is it’s passive form of information capture.
Q: What are you doing next? How do you see Facelogger evolving?
Gradman: Currently, a Facecard only expresses information captured in the 30-second clip. But APIs for face identification are getting really good. Soon the Facelogger will dig through my social network, and connect a Facecard to the social profile of the person it represents.
Next I will passively capture my meals, and use Mechanical Turk to help catalog my meals.
Face logging and food logging are only two well-defined applications of life-logging. I intend to identify others, and make them available as software for anyone wearing a compatible life-logging rig.
Q: Anything else you’d like to say?
Gradman: Face-blindness and poor memory for names are widespread problems! I designed the Facelogger with my own shortcomings in mind, but I’m now examining how I can make these tools more widely available, perhaps as a subscription service.

Ernesto Ramirez strikes again! His recent talk at QS San Diego called Quantified Self on a Budget is one of our most viewed videos. We were lucky enough to have Ernesto come up to San Francisco to share his thoughts on how self-tracking can enhance your memories and help you reflect on your life. He is currently using two tools: 4squareand7yearsago to tell him every morning where he checked in a year ago, and Lifelapse to take pictures every 30 seconds as he goes about his day. Ernesto has started a Visualized Self experiment, creating a History of Ernesto. It’s almost as though self-tracking is a sort of neural prosthesis enhancing our humanity. (Filmed at the Bay Area QS Show&Tell Meetup #19 at Singularity University.)
Calling all beta testers!
Kresten Bjerg, at the Institut for Psykologi at the University of Copenhagen, is working on an open source electronic diary app that uses pictograms or “syntactic glyphs” as part of the thought-recording process. He is looking for people to help test the diary and possibly build on it. Please write directly to Kresten if you are interested in checking it out.
Here are some of the pictograms he has built into the diary:
Mark Carranza has been keeping a list of his ideas since 1984. His list has more
than a million entries, with more than 7 million connections between
entries. Although the media window above appears to contain a video of Mark’s talk at QS #3, Mark preferred that MX not be shown yet, so what you see on screen during the sound recording of talk are the faces of some
of us in group, listening with interest. But even without being able to
see the tool in action, Mark’s description is wonderful. Some
highlights: Mark describes his personal workshop as “The institute for
the prevention of design.” His program is DOS software, last updated in 1992. MX
stands for memory experiment, but if you say these letters again and
again you will notice another allusion. Any element in a list of thoughts can be associated with any other element. “I use it as a thought tool,” Mark says.
At last Monday’s meeting, Mark gave us a quick update on the MX project. Since Esther Dyson was sitting nearby, he went back into his notes and in an instant could recount every time he had heard Esther talk, and what she had talked about. From the look on her face, it seemed that Esther’s memories were being activated by this exercise, too.
Below are Mark’s complete notes from the meeting. I am using them to construct my own account of what happened, and finding them marvelously helpful. The key, for me, in appreciating this experiment, is to understand that these notes are memory aids. They are not meant to stand alone as a story about what happened. Rather, their magic lies in stimulating a chain of associations that bring the older train of thought to mind, updating it in the process. This is working for me after a week has passed, and it seems to work for Mark after years have passed. If you were at the most recent Show&Tell, go ahead and review Mark’s notes and see if they work for you.

These are the notes I took at the 8th Quantified Self Meetup, Monday
night, September 14, 2009. I wrote them paper at the meetup, then
entered them into my e-memory system MX a day or two after. I hope
sharing them helps people re-encounter, re-think, at least some of the
great ideas shared there.
For those interested, Gordon Bell and Jim Gemmel will be presenting
their new book ‘Total Recall: How the E-Memory Revolution Will Change
Everything’ at PARC Forum in Palo Alto, next Thursday, September 24,
2006 from 4 to 5pm. Details at: http://www.parc.com/event/948/

each individual list here, 75% to 87% are new entries, thoughts never

Each entry on a list is itself a list, a link to the list of which
it is the title. It’s trememdously important that every connection is
a cross-link. For example, #31 on the first list is shown as a list,
on which the first list is #3. I’ve also included from the first list,
lists there numbered: 32, 33, 34, 37, 38, 39. These are all the talks

Please forgive the software not being ready to release where these lists are active. Thanks!
Deep mysteries of human nature will be exposed by self-tracking, aspects of our behavior so disconcerting and bizarre that they will lead us to question whether we understand ourselves at all. I know this is true because such disconcerting results are already being produced at a rapid pace by experimental psychologists, and self-tracking brings the methods of experimental psychology into our daily lives; if, that is, we think we can stand to learn the lessons they teach.
Watch this video published from a story in New Scientist by Lars Hall and Petter Johansson.
[I]n an early study we showed our volunteers pairs of
pictures of faces and asked them to choose the most attractive. In some
trials, immediately after they made their choice, we asked people to
explain the reasons behind their choices.
to them, we sometimes used a double-card magic trick to covertly
exchange one face for the other so they ended up with the face they did
not choose. Common sense dictates that all of us would notice such a
big change in the outcome of a choice. But the result showed that in 75
per cent of the trials our participants were blind to the mismatch,
even offering “reasons” for their “choice”.
This is troubling enough, but there’s more. When people are fooled into thinking they made a different choice than the one they actually made, and then articulate their “reasons” for this supposed choice, they then may actually change their future preferences to conform to their confabulated preference.
Importantly, the effects of choice blindness go beyond snap judgments.
Depending on what our volunteers say in response to the mismatched
outcomes of choices (whether they give short or long explanations, give
numerical rating or labeling, and so on) we found this interaction
could change their future preferences to the extent that they come to
prefer the previously rejected alternative. This gives us a rare
glimpse into the complicated dynamics of self-feedback (“I chose this,
I publicly said so, therefore I must like it”), which we suspect lies
behind the formation of many everyday preferences.
Lars Hall and Petter Johansson lead the Choice Blindness Laboratory at Lund University, Sweden. At the end of their New Scientist piece, they suggest that learning about this experiment should make people better at understanding their own choices.
In everyday decision-making we do see ourselves as connoisseurs of our
selves, but like the wine buff or art critic, we often overstate what
we know. The good news is that this form of decision snobbery should
not be too difficult to treat. Indeed, after reading this article you
might already be cured.
Unfortunately, this is not convincing. It is common for biases persist even when we are warned about them. I suspect we are in no position to stand guard over our judgments without the help of machines to keep us steady. Assuming, that is, that deliberative consistency is a value we care to protect.
In a hospital or a doctor’s office, you are usually asked what medications you have taken recently. Under conditions of distraction, I’m sometimes uncertain if I’ve given a correct answer. I think to myself: “okay, if I’m a professional question-asker, and I’m doubting my memory in this situation, how often are incorrect responses given by people who have more prescriptions and less practice?
We now know the answer.
A study by Dr. Stephen Persell at Northwestern University looked at 119 low income patients, average age 55, under treatment for high blood pressure. Nearly fifty percent were unable to name a single medication listed on their chart. The paper will be published in the November issue of the Journal of General Internal Medicine. (Press announcement here.)
Obviously, there should be a machine to remember this for us. But this is more easily said than done. Even when drugs are administered in a hospital setting, errors are common.
The solution hospitals many beginning to use is to track all drug dispensing with bar codes. It’s a complicated, expensive method, but a paper published in the Archive of Internal Medicine last April reported that the money saved through reduction in “adverse drug events” from implementing bar codes would recoup the investment within one year.
The question now: how can quality-of-care innovations like pharmacy bar codes give us better ability to know and control our own medical information?
Why not give patients a small booklet, similar to the booklet the Savings & Loan banks gave to depositors. Thought these booklets were cheap to produce, their design and the way they were used suggested they were valuable. Customers would hand their booklet to the teller, who would fill in the deposit or withdrawal amount and the new balance.
I’m not suggesting that prescription records be kept only in little paper booklets. No – the booklet would be a patient interface to the electronic prescription records that doctors, hospitals, and pharmacies are beginning to put into a standard electronic form. At the end of a visit to the doctor, we hand our booklet to the receptionist. The receptionist prints out sticky labels and presses them into the booklet – one label per prescription, one page per visit. The label would show the drug name, dosage, and bar code. We could take this booklet with us to the pharmacy. If a generic was substituted, the pharmacist could print out a label and add it to the page.
This is not as elaborate as it sounds. The booklet would sit on top of bar code technology that is already being installed. It is just a matter of giving the information to the patient in a handy form: portable, well-organized, and standard. It would work for people of all ages and temperaments, not just for those who like to track their medications online. Because the prescription book is just an interface, it doesn’t matter too much if it gets lost. A new one can be easily made. But it would also function in situations where the online information was not available – for instance, a patient could read it to a nurse over the phone.
This may be wrong and I’d be happy to hear about why.
