Flaxman (1954): How to keep up with medical literature
Editor’s note: In the 1950’s learning was easy. A pubmed search for ‘intensive care’ or ‘critical care’ for that year would return 1 article. Do the same literature search for 2015 and there are 24,000 citations. Let’s say only 1 % are relevant, you would still need to read 50 articles every single week to keep up to date! This blog has been cross posted, with permission from The Bottom Line (TBL), and provides some invaluable tips on how to readily and efficiently assimilate medical literature. Even better, the resources are either free or heavily discounted with ICS membership! He also selects some landmark ICM papers of 2016. What would be your favourites? Please do join the discussion. /Steve Mathieu.
Keeping up to date with medical literature
This blog is following a talk I gave at the Wessex Intensive Care Meeting on 16.06.2016. The first part is about how to keep up to date with the medical literature. The second part lists what I consider to be the top critical care trials of the last 6/7 months. In the presentation I talked about these in more detail, but as we are planning on covering some of these for The Bottom Line I don’t want to give the game away! The accompanying presentation slides can be found here.
There is a long time delay between the publication of new evidence and the use of this evidence in clinical practice. It has been reported that this knowledge translation takes an average of 17 years. This delay in knowledge translation leads to patients receiving less than optimal treatments, or even receiving treatments that result in harm. It also results in unnecessary expenditure for healthcare organisations.
To provide our patients with the very best care we need a system to be able to keep up with the important literature whilst discarding the vast majority that is either irrelevant or of poor quality. With the use of modern technology and social media this is now easier than ever. I’m going to tell you a little about the different systems that I have used to keep up to date. I’m sure you already use lots of these but hopefully there will be something new for at least some of you.
Best web sources
Key Message 1 is, if you haven’t signed up to the Critical Care Reviews Newsletter, then sign up today. Rob MacSweeney produces a weekly email alert of the latest critical care papers. As well as producing the weekly update, his website has links to top 100 trials, as well as the top papers for each system, such as respiratory, renal, nutrition, all focused on intensive care. It’s a fantastic resource that’s great for learning, teaching, journal clubs and expanded cases summaries.
The BMJ produce evidence updates with email updates of what they think the key trials are from over 120 journals. You sign up for your specialty and then decide how important a trial has to be rated by them for it to be included in your email alert. For critical care if you want everything you get told about 20 trials a month, where as if you just want the massive trials you get a handful a year. This is a free service and you don’t have to be a BMA member to sign up.
Intensive Care Monitor produces a bi-monthly summary and expert comment on the key literature. The advantage is that you get a focused critical appraisal of each paper. The disadvantage is that you have to pay, it costs £40/year for the online version. Although if you are a member of the Intensive Care Society you can get up to a 50% discount.
Social media and podcasts
I think most trainees and a number of consultants will now be on twitter. For those of you who aren’t then it can be uses as a great resource for signposting. You follow other people and get a feed of everything that that they post. If you choose wisely and follow key people and important medical journals then you can use this as a gateway to information. The advantage is that it is instantaneous. When a big trial is published you can find out very quickly as someone will have tweeted about it. The big disadvantage is that shouldn’t take anything that is posted on twitter at face value. It really should be used to signpost you to the information for you to review yourself rather than believing what someone has tweeted.
I’m sure lots of you already listen to medical podcasts on the way to work. The ones I have found particularly useful are Crit-IQ which does a monthly round up of the latest trials, The Intensive Care Network from Australia post a large number of podcasts from all their regional meetings, the ICS have posted all their presentations from their State of the Art meeting, as do the SMACC meetings. Scott Weingart has covered nearly 200 podcasts on lots of ED critical care topics. My favourite Emergency Medicine podcasts are St. Emlyn’s, The Skeptics Guide to EM, and R.E.B.E.L.EM.
All of the strategies used so far have been described as push techniques where journals and services push information at you telling you what to read or listen to. The next strategies can be described as pull techniques where you pull the information you want.
To try and pull information from lots of websites you can set up what is known as a RSS feed. Feedly is the app I have used for this. You can subscribe to websites such as The Bottom Line, Intensive Care Network as well as journals. Each time a new article is posted on the website or journal it will appear in your RSS feed. This way you get all the information in one place and do not have to go to each website each week, or read multiple emails from journals telling you about their latest trials.
Read by QxMd is an app that allows you to get feeds of the medical journals of your choosing. It has the advantage that it links in with your Athens account so that with a single click you get access to the full text articles that your library subscribes to.
Set up a search online
The final method is the one that I predominately use. PubMed allows you to set up searches with daily or weekly email alerts. In my search I include the important critical care journals, but I also have a few searches such as intensive care AND randomised trial or intensive care AND evidence based medicine. This means that if there is an important article in a journal that I do not subscribe to I still get alerted to it. The advantage is I get all the information I want in one daily email. I find I can read one email a day and a get to the bottom of it, where as with Feedly and QxMd I never used to swipe through all the journals I used to subscribe to. The disadvantage of PubMed searches is that it still takes time. There can also be information overload. Especially with journals such as NEJM there a lot of letters that get into PubMed that are not relevant to my practice, but its very easy to swipe past those. Overall I have found it the best way for me to keep up to date as it provides me with all the important articles, but its still just in one manageable email. The best place to read about how to set up your PubMed search is via Natalie May’s blog ‘Drinking from the Firehose – Keeping up with the literature‘
