    Got my first letter yesterday! Loved it. I feel like I am a part of something great that is certainly just starting to materialize. Feeling a strange sensation of community around it all. Maybe you are on to something here! Who would have ever thought that people would truly print out words on paper just to have it sent through the mail to another person’s mailbox. Next thing you know, peoe will likely be growing their own food and walking or riding bikes everywhere. It’ll by no means do the job, damn progress.

    6 Ways for Radiologists to Use Social Media

    By Deborah Abrams Kaplan | July 12, 2012

    ——————————————————————————–

    Social media for physicians is not just for marketing your practice. And it’s not just for the young doctors. Yes, it takes time to learn, but it’s free — helping you stay abreast of the latest radiology news, and connecting you with a wide array of colleagues.

    But before jumping into the social media fray, take a step back and ask yourself what problems you’re trying to solve, said Lee Aase, director of the Mayo Clinic Center for Social Media. Then pick the right tools to help you solve that problem.

    “Nobody has time to waste on frivolity,” Aase said, “but the tools make it possible to connect with people of common interest all over the world.” Through its various social media accounts, the Mayo Clinic is connected with people from more than a hundred countries. “That’s pretty astonishing with no out-of-pocket expense. It’s just your time. You can build affinity groups and communities of interest in a way that 20 years ago wouldn’t be possible,” said Aase.

    Whether connecting with your own health care system, other radiologists or health care consumers, you can customize what you want to see and from whom, said Safwan Halabi, MD, a radiologist and director of imaging informatics at Henry Ford Health System. “That’s what social media does really well.”

    We reached out to a few health care pioneers using social media in innovative ways, taking the platforms beyond their use as a forum for sharing status updates and promoting their practices. In their own words, these experts detail how six social media programs can help you:

    Crowdsourcing

    Carl Miller, MD, radiologist at Johns Hopkins Medical Center:

    “We used it to select a new clinical system, a web-based image viewer. Ordering physicians can use this lightweight PACS to get access to images wherever they are, like on their iPad or through a web platform. We didn’t know how or where our physicians would use it. It’s a young technology, so we didn’t have an established knowledge base of vendors. We created a crowdsourcing platform to answer those questions and involve physicians in the selection process. Rather than (consulting) one or two peripherally involved physicians, with business people making the decision, we were able to involve over 300 clinicians throughout the enterprise — on all levels — in collecting needs and uses, and evaluating the three platforms we already vetted. They were able to vote, rate and evaluate through this platform. We got a robust, deep feedback of what they needed, what they liked and why. People were excited about it. When you have 300 physicians participate in a vendor selection, you end up with a mandate.”

    Twitter

    Lee Aase, director of the Mayo Clinic Center for Social Media:

    “A low effort, high potential impact way of staying up on the latest news is using Twitter. Set up an account and spend a lot of time just listening. Use it to find people who are tweeting about topics that are interesting to you. There are hash tags out there that relate to every topic under the sun, especially medical specialties or by medical interest. Find people who regularly tweet about those topics, and you’ll have a rich stream of people who do your research for you. They’re bird-dogging topics that would be interesting.”

    Carl Miller, MD, radiologist at Johns Hopkins Medical Center:

    “I learned about a new type of diabetes, LADA diabetes, an autoimmune type of diabetes. I don’t practice in diabetes care regularly, so I haven’t been reading literature about it. I learned about this new disease from a patient on Twitter. That’s the world we live in now. Patients are experts in disease; they have access to the same quality of information we do. Humans don’t have the capacity to know everything there is to know about everything. The days of memorizing it all are just gone. I was able to be educated on it through Twitter through a tweet chat.”

    Safwan Halabi MD, radiologist and director of imaging informatics at Henry Ford Health System:

    “From a research perspective, I find myself learning a lot from other colleagues at other institutions by following their tweets and retweeting.”

    Doximity

    Carl Miller, MD, radiologist at Johns Hopkins Medical Center:

    “This social media platform is for physicians specifically. It’s HIPAA compliant and has built-in features for physicians. Physicians are using that to communicate. It’s a physician-to-physician media platform from the same people who founded Epocrates.”

    Lee Aase ,director of the Mayo Clinic Center for Social Media:

    “Physicians have immense difficulty keeping up with all the journals. Through Doximity and Twitter you can find people who actually have read the article first and see something that’s of particular interest. You can follow people you trust, you can build on their efforts. They’re pointing out the things that would be worth your attention.”

    Yammer

    Lee Aase, director of the Mayo Clinic Center for Social Media:

    “One platform we’re using is Yammer, that’s a cross between Facebook and Twitter, for people who work for the same organization. You sign up using your work email address and only people with the same domain email address can be part of the network. Because of that, you’re in a secure place to have conversations and share information throughout your organization. It provides a record of what was discussed and decided, versus it being in everybody’s inboxes. Yammer, and there are other platforms like that, is free to try. If there’s longer term interest, you can get a premium version with more control over administrative rights.”

    LinkedIn

    Safwan Halabi MD, radiologist and director of imaging informatics at Henry Ford Health System:

    “When I first signed on to LinkedIn two to three years ago, I thought it wasn’t very helpful for medicine-related stuff. It was more for the business world. But I find that more and more people are finding me through LinkedIn. I’ve gotten requests for meetings or interviews. Though I’m not job searching, I can see that if people write recommendations for me, that would be helpful if I were looking for a new job. I share my tweets on LinkedIn rather than on Facebook, because people go there more for business.”

    Lee Aase, director of the Mayo Clinic Center for Social Media:

    “From a job search perspective, LinkedIn is really good because if you’re looking to interview for a position, you can see who is a connection who works there already, or a connection-of-a-connection who can do an introduction for you to find out what it’s like to work there.”

    YouTube

    Safwan Halabi MD, radiologist and director of imaging informatics at Henry Ford Health System:

    “I subscribe to the Henry Ford YouTube feed, and learn a lot about what’s happening [at Henry Ford]. It’s such a large system and there are so many silos in a health system. Our chief medical officer does a video series with employees in the hospital. I also learned about a neurologist at Henry Ford who set up a system where he e-rounds using the iPad, with a Skype conversation. Residents or the nurse can give the patient the iPad (when he’s working at a different hospital). He asks the things he’d ask if he were there in person. It’s a nice way to communicate with someone and not delay.

    “I’m doing a research study on clinical decision support. A great way, instead of email blasts, is to have a video of what the research study is about. It’s so easy to do. You do have to have the basic infrastructure of those who are savvy with it, a video team. But you could do the video on your phone too.”

    Lee Aase, director of the Mayo Clinic Center for Social Media:

    “Where our physicians have found it helpful is that you can go into depth in discussing and covering subjects that are not of broad interest. You can do a five minute video on a topic, and the goal isn’t to get millions of views, but to provide meaningful content to those who would be interested in it. Physicians are typically concerned about being taken out of context – you can provide all the context. You have the ability to have an extended two to three minute clip from the physician talking about why they did that study.”
