Towards the minimally disrupted quantified self

One of the emerging movements in healthcare is the quantified self movements. Led by a bunch of tech-savvy self-confessed geeks the quantified self movement is all about collecting personal data and using it to inform life decisions, health care decisions and behaviour change to improve overall well-being. These life-loggers are measuring their habits, food intake, activity levels, mood, heart-rate, blood pressure, blood sugar and a host of other person-reported outcomes and physiological measures and charting them on paper or in spread sheets. Whilst this seems like a small sub-culture most people with smart phones have downloaded at least one health related app that can be used for life-logging. Persistent use is not always durable and perhaps it is because life-logging, like much other healthcare activity is burdensome. You have to spend a lot of time entering data yourself. Well maybe this is all starting to change and being a quantified self is becoming less burdensome.

Victor Montori has been advocating for minimally disruptive medicine, the aim being to reduce the overall burden of healthcare (not just the burden of disease) for patients, particularly those with chronic medical conditions like diabetes. Many chronic medical conditions actually already require individuals to include some form of life-logging as part of their healthcare routines e.g. recording blood sugar levels or blood pressure.

Smartphones and other smartphone facilitated devices are starting to enable data collection in a minimally disruptive way. For example accelerator and GPS-enabled smartphones, or smartphones linked wirelessly to other small devices like a Fitbit or a Nike Fuelband, can track exercise and other activity levels. Calorie consumption can be inferred and flights of stair counter. The same phone or added devices can be used to measure sleep patterns. Increasingly attachments to the phones can measure various physiological parameters in a non-invasive way. Apart from the occasional re-charge (they aren’t solar or movement powered yet) they are pretty much plug & play, set & forget. All you need to do is make an effort to check out the data in the form of customised reports and decide how you will act on them.

To take it a step further companies such as Soma Analytics have apps that move beyond you recording your mood directly to actually inferring your mood by analyzing your voice patterns during phone conversations. This in turn allows a calculation of your stress levels and can give you feedback and advice about stress management.

Another variation is to use the phone using the GPS tracking facility to record activity levels as a marker of a patients’ “social pulse”. For example, if an older person changes their activity patterns based on monitoring of the phone movements then this might be a sign of decline in functional status. Deborah Speaking at @TEDMED Deborah Estrin has referred to this as our “small data” and is encouraging processes to obtain this data from telecommunications providers.

All of this data can be used for personal use but uploaded to the cloud and given the right permission your medical practitioner could access the data remotely and in return provide analysis, interpretation and clinical advice on the basis of your data. Automated alerts flowing to healthcare provider or patients could be a form of minimally present telemetry.

Looking at these existing and emerging technologies one can see that having a data-driven life doesn’t need to be a full-time job even if you are collecting data 24/7/365. Even the activities which might require an effort at data entry, like recording diet or medication use, might become more automated through image recognition software or barcode/QR-code scanning. This could be continuous and uninterrupted for individuals using google glass. I think we can call this the minimally disrupted quantified self.

Things they didn’t teach in medical school: Part 22 Project Management #TEDMED

Something not taught in medical school is project management. Although at medical school you might undertake assignments and similar activities, unless you are allocated a research project it is unlikely you will have any formal instruction in project management. I, in fact, don’t consider myself to be especially good at hands-on project management and work better as a collaborator on projects rather than running them directly. Project management is related to time management. You an think of time management as about managing your time to do projects and visa versa project management is a about completing tasks on time.

It is important first of all to recognise a project when it is either handed to you or you come up with the idea.

For me the simplest definition of a project is any activity that can be broken down into smaller tasks to produce an outcome which is more than the sum of the individual parts. Using this definition a project may be small e.g. preparing the meeting roster for a year or large e.g. designing a new medical school curriculum.

There are some tips for managing a project:
– really identify what the purpose and aim of the project is and visualise how the finished project will look – what are the deliverables
– estimate the resources you will need and the time you will need
– identify who is critical to your project – for example, if you need statistics advice for a research project get it early
– break the project down into the smallest tasks possible and work out what in what order they should be completed (and which tasks depend on another tasks being completed – a dependency)
– identify what will stop the project from being finished
– based on the above decide if your project is feasible or not
– identify stakeholders and collaborators
– once the project has started have a regular review process to check progress

Last night at the opening session of TEDMED 2013 Professor Rafael Yuste spoke about the relationship between pursuing big science and his passion for mountaineering. He broke them both down to 3 steps: assemble the team, map the course and keep the summit in sight. The scientific summit he plans to climb is the Brain Activity Map now known as the Brain Inititiative which was announced by Barack Obama 2 weeks ago. This is the moon project or human genome project of the decade. You can see him talk @TEDMED
