Health search is everywhere• Last night, in J.K. Rowling’s The

Casual Vacancy, I read…– “She navigated away from the

Parish Council message board and dropped into her favorite medical website, where she painstakingly entered the words "brain" and "death" in the search box.The suggestions were endless. Shirley scrolled through the possibilities…”

“Democratization of location”

?

Before looking at mobile health search, need to ask if people use mobile devices

• 321.7M wireless subscribers in US at end of 2011– Penetration of 101%

• Smartphones now outnumber feature phones for the first time in the US

• 1 in 8 internet page views are on smartphone or tablet, doubling in just a year– Comscore 9/12

• Almost impossible to focus only on laptops and desktops when considering health information seeking

Not only are mobile devices used but they may eradicate the “digital divide”

• Smartphone ownership in US– 49% of Hispanics– 47% of African Americans– 42% of whites– Pew Internet & American Life Project 9/12

Some people are only using mobile devices

• 34% of US household are wireless only– Stephen J. Blumberg, Julian V. Luke, Wireless

Substitution: Early release of estimates from the National Health Interview Survey, July-December 2011, National Center for Health Statistics, 2012, http://www.cdc.gov/nchs/data/nhsr/nhsr061.pdf

• But one device or many?

Some people are using lots of mobile devices

• 40% of US households have 3 or more mobile devices in addition to their PCs & TVs

• Differences in – Where mobile phones and tablets are used– Frequency of use

What do mobile devices provide health seekers?

• Immediacy and access• Affinity• Multiple methods of input/output• Context

Immediacy and access

• 85% of respondents had cell phones– 53% of these, or 45% of US adults, had smartphones– Cell phone owners

• 31% look for health or medical information• 11% have health apps• 9% receive text updates or alerts from doctor or pharmacist

– Pew 9/12 via Susannah Fox• Mobile devices may be used immediately after leaving

doctor’s office, especially with a new diagnosis or prescription– Impact on health literacy especially recall and retention– Impact on patient-physician communication

• Could patients listen or ask questions differently due to reliance on search?

More lovable when they’re cute and little

Affinity

• People relate to computers differently than people– What about smartphones? Tablets?

• Mobile users have an ongoing intimate and personalized relationship with their “digital appendage” or “cognitive prosthetic device”

• Do people seek information differently?– Searches on mobile devices tend to be about private/sensitive

conditions: sexually transmitted diseases, mental health• How is use changing?

Number of search results viewed on smartphone versus computer

What do mobile devices provide health seekers?

• Immediacy and access• Affinity• Multiple methods of input/output• Context

Context• People are exposed to a wealth of contextual

information: what they see, hear, feel, remember– How do people act on it using their mobile device?

• Multiple devices monitor and record contextual information, including sensors and GPS– How do weather, location, time of day, blood

pressure, etc. impact personalization and tailoring?• Big data and predictive analytics

Sometimes asking questions leads to more questions: fighting the Hydra

Some of my questions…

• Do people conduct health searches differently– On smartphones or tablets?– In mobile browsers or mobile websites or app stores or apps?– Using text or voice?– Based on location?

• Are people more or less easily able to locate “helpful” information?

• Are there different indicators of quality or reliability?• How can mobile health search better help people to seek

information and achieve their health goals?

Near future

• Design for mobile first instead of retrofitting health websites into mobile format

• Make smarter smartphones and better integrate sensor data

• Learn from strategies used by well-funded retail– Use of big data and predictive analytics to provide

accurate and timely health information

Future• From digital appendages to… Google glasses• The ultimate in seamless mobile health search?• Stay in touch
