Ten days in and things to do

It's been a successful launch of the new version of the site.  We've had lots of sign-ups to the Premium version and that includes a number of institutions - so, so far so good.  Fortunately, we've had no ill-feeling expressed around the move to Freemium, I imagine most users understand the reasons.  We have had lots of feedback which has started a mini-development cycle.  So, things that we're planning on doing in the near future include:

  • Improved export meta-data. Currently we only include basic data such as title, publication and year.  We're now planning to extend that to include authors, volume, issue, page numbers and abstract.
  • OpenAthens.  We're still exploring this but it looks like it's a route that we need to go down.  The only hesitation is the cost!
  • Institutional pricing.  Even though we planned it and spoke to a number of people I think the way we've packaged institutional subscriptions is overly complex and off-putting.  So, we're working hard to simplify this and we aim to roll out a new approach in the very near future.
If there are any other improvements you'd like to see, feel free to email me: jon.brassey@tripdatabase.com

The first 24 hours

Its been 24 hours since the new, Freemium, version of Trip went live.  A few things I've learnt:

  • People have not been openly hostile about us moving to the new business model, I was expecting some abuse. I got some mild complaints from Twitter - but if that's the worst of it.
  • People seem happy to pay and we have a number of paying customers.  Before we went live I was trying to think what might be good, bad and terrible and couldn't actually come up with anything sensible.  However, the response so far has been encouraging.  But, I do need to stop checking the payments system every hour.
  • Institutional interest has exceeded expectations and it's been really interesting dealing with many of the queries.
  • Internet Explorer (version 8) is not liked by Stripe, our payment system.
  • The system to reset passwords was a bit naughty and refused to send out links to reset the passwords.  Fortunately, that is now fixed!
  • I'm beginning to better understand some of the background functionality that I'd been not really thinking about.
  • I really need to think about VAT when setting up a payments system.
I think the biggest realisation is that, to make this model work, will require significant hard work on my part!  Anyone out there with (a) good sales skills (b) spare time (c) will to work on payments by results??

The New Trip Database

The new version of the Trip Database is live and to help celebrate we've produced a beautiful infographic.

While to many the new site will not look massively different there have been some huge changes.  Perhaps the biggest has been the adoption of the Freemium business model.  What was previously freely available at Trip remains, largely, free but for those who want an enhanced service there is a Premium (paid for) service.  We have adopted this model based on the absolute need for financial security. 

So, what do those purchasing the Premium model get?

More content
  • Approximately an extra 100,000 systematic reviews (including systematic review type content such as HTAs), more than double available via the free Trip.
  • Millions of free full-text articles
  • Ongoing clinical trials database of over 175,000 clinical trials
  • Access to a large medical image database
  • Tens of thousands of clinical videos
More functionality
  • Export of records to reference management software
  • The ability to easily exclude certain content types (e.g. eTextbooks)
  • Trip educational credits
  • Article views, see which articles are most popular for your search
Other things

Another new feature is moving to a more secure site with a new password system (this is for both free and premium users).  This will require users to renew their login/password details but it's a one-off - so hopefully not too traumatic.

Finally, and mentioned above, is the new Trip Evidence Service. Run by experienced and skilled information experts the Trip Evidence Service can provide various services: formal literature searches, horizon scanning and evidence reviews. Given the varied staff skills the service can also offer bespoke information services.

So, why delay, click here to upgrade to the new Premium Trip today (click here).  NOTE: Institutional subscriptions are available,

Coming soon

We've moved in to the final stages of testing for the new site.  If you've not seen it already, we posted a 'taster' around ten days ago. Assuming the testing goes well, we aim to go live over the weekend of the 16/17th May.

As well as the upgrades we're moving to a new and more secure site.  The only thing you'll notice is the need to change your login and password.  This is a necessary 'discomfort' as the old system was very old and not particularly secure, so there was a pressing need to upgrade!



This is a really important milestone for Trip.  Assuming it goes well and a reasonable number of users (and organisations) sign-up to we will be financially stable - the first time in years.  It should give us a solid foundation to base on next tranche of improvements - based on the work highlighted in this blog post.

Dental evidence

As part of a wider piece of work I've been looking through the search logs and clickstream data associated with the dental specialty.  It's interesting, and the following information is based on the 1,100+ registered users on Trip who have ticked the clinical specialty of dentistry.

  • periodontitis
  • dentistry
  • orthodontics
  • dental caries

Evidence Live, systematic reviews and the US Air Force

I'm just back from the wonderful Evidence Live.  While I was away I saw this news story Is the West losing its edge on defence? and I was particularly drawn to the following passage:

The military have also contributed to their own misfortunes by conspiring with defence contractors to build ever more expensive weapons that can only be afforded in much smaller numbers than those they are supposed to replace.

Pierre Sprey, chief designer on the F-16 fighter noted the ruinous consequences of buying stealth aircraft at hundreds of millions of dollars a copy.

"It's a triumph of the black arts of selling an airplane that doesn't work," he said.


This fits in very nicely with my perspective on systematic review methods, and was one of the main threads in my presentation on the future of evidence synthesis.  The current methods of systematic review production are costing way too much for what they deliver.  If you consider that the majority of systematic reviews rely on published trials they are inherently unreliable.

In the EBM world we're buying F-16s...!

More to follow on this theme.

UPDATE: The wonderful Anne Marie Cunningham has pointed out (see comments) has pointed out that the consequence is of buying the really expensive stealth fighters (not F16s).  That's a consequence of rushing a blog post so soon after a vigorous conference!  The point remains - purchasing too expensive planes has caused massive problems.

A taste of things to come

It is hopefully self-explanatory...
