The challenge

If you’re given an injection, in hospital, anywhere in the NHS, there’s a strong likelihood that the person injecting you will use the IMG – the Injectable Medicines Guide.

It’s how they know all the vital information about the drug they’re administering; from the best injection site to how much to give you, medicine interactions, and more. And it’s used millions of times a week.

With guidelines changing regularly – and with vital patient safety at stake – the IMG has to be easy to use, exceptionally clear, and simple yet secure to update. But how best to do this digitally?

The existing website was starting to show its age. So, it was time for the IMG to have a radical digital overhaul. Although it had been built and long-maintained by an in-house team, the decision was made to put it out to tender, via the government’s Digital Outcomes and Specialists framework.

The project journey

Having won the tender, our first job was to get ourselves to hospital and watch the IMG in action..

The question of useability is one we take very seriously. Many of our projects deal with secure data for time-poor users, often in fairly stressful environments and as part of specialist roles.

We knew that although some IMG users would be administering the same drug multiple times a day, and know it inside out, the system has to be robust enough for much less comfortable environments. It could be used by a nurse who’s never worked on that ward before, by a nurse who might be less technically adept than other colleagues, or by a tired nurse, working as part of a crash team, under pressure at 5am.

And when you take into account that, if the NHS trust has subscribed to the IMG, every ward from A&E to urology, and from obstetrics and gynaecology to geriatric will need access to it, it has to be clear and easy enough to use in the most varied and tricky of situations.

So we took to St James’ Hospital in Leeds for deep user research, watching and talking to the nurses who were actually using it. It was an eye-opener, showing us first-hand the difficulties they face, from department to department. Challenges that will be replicated and multiplied in NHS trusts all over the country.

That process meant we were not only able to pinpoint numerous additional improvements, but also take our direct findings back to NHS leaders and prove the validity of our recommendations, as witnessed on the frontline.

Once we’d refined and agreed our approach, we spent around a year building the system. Then it was time to migrate the information from the old website to our new, more modern and usable format. And add thoughtful, user-friendly touches, such as printable posters with QR codes, for medics to attach to the medicine cupboard, providing easy mobile access to the IMG exactly when and where it’s needed.

The impact

User acceptance testing is running like clockwork, with nurses responding very positively to the new, clear interface and easier access.

The IMG team is delighted with the improved editing process, with robust audit trails built in, to make sure the system is super secure.

With rollout happening imminently, everyone involved is confident that the new IMG is set to save the NHS vast amounts of time, while making nurses’ lives that little bit easier.

Bringing a fresh Perspective to essential pension industry data

Pendragon, a specialist provider of legal and regulatory information services to the UK pensions industry, is rightly proud of its flagship product, Perspective. But this indispensable electronic information service was showing its age – and resisting attempts to drag it up to date.

To hang on to its position, cloud-based convenience was a must. But two previous attempts to shift it from desktop to SaaS had failed for being too slow. How could we overcome the technical barriers to bring Perspective up to date without losing performance?
