ISPOR Europe 2018, which took place in Barcelona on the 10th-14th November, was an exceptional conference. It had a jam-packed programme on the latest developments and most pressing challenges in health technology assessment (HTA), economic evaluation and outcomes research. In two blog posts, I’ll tell you about the outstanding sessions and thought-provoking discussions in this always superb conference.
For me, proceedings started on Sunday, with the excellent short-course Adjusting for Time-Dependent Confounding and Treatment Switching Bias in Observational Studies and Clinical Trials: Purpose, Methods, Good Practices and Acceptance in HTA, by Uwe Siebert, Felicitas Kühne and Nick Latimer. Felicitas Kühne explained that causal inference methods aim to estimate the effect of a treatment, risk factor etc. on our outcome of interest, controlling for other exposures that may affect it and hence bias our estimate. Uwe Siebert and Nick Latimer provided a really useful overview of the methods to overcome this challenge in observational studies and RCTs with treatment switching. This was an absolutely brilliant course. Highly recommended to any health economist!
ISPOR conferences usually start early and finish late with loads of exceptional sessions. On Monday, I started the conference proper with the plenary Joint Assessment of Relative Effectiveness: “Trick or Treat” for Decision Makers in EU Member States, moderated by Finn Børlum Kristensen. There were presentations from representatives of payers, HTA agencies, EUnetHTA, pharmaceutical industry and patients. The prevailing mood seemed to be of cautious anticipation. Avoiding duplication of efforts in the clinical assessment was greatly welcomed, but there were some concerns voiced about the practicalities of implementation. The proposal was due to be discussed soon by the European Commission, so undoubtedly we can look forward to knowing more in the near future.
My next session was the fascinating panel on the perils and opportunities of advanced computing techniques with the tongue-in-cheek title Will machines soon make health economists obsolete?, by David Thompson, Bill Marder, Gerry Oster and Mike Drummond. Don’t panic yet as, despite the promises of artificial intelligence, I’d wager that our jobs are quite safe. For example, Gerry Oster predicted that demand for health economic models is actually likely to increase, as computers make our models quicker and cheaper to build. Mike Drummond finished with the sensible suggestion to simply keep calm and carry on modelling, as computing advances will liberate our time to explore other areas, such as the interface with decision-makers. This session left us all in a very positive mood as we headed for a well-earned lunch!

There were many interesting sessions in the afternoon. I chose to pop over to the ISPOR Medical Device and Diagnostic Special Interest Group Open Meeting, the ISPOR Portugal chapter meeting, along with taking in the podium presentations on conceptual papers. Many of the presentations will be made available in the ISPOR database, which I recommend exploring. I had a wonderful experience moderating the engaging podium session on cancer models, with outstanding presentations delivered by Hedwig Blommestein, Ash Bullement, and Isle van Oostrum.
The workshop Adjusting for post-randomisation confounding and switching in phase 3 and pragmatic trials to get the estimands right: needs, methods, sub-optimal use, and acceptance in HTA by Uwe Siebert, Felicitas Kühne, Nick Latimer and Amanda Adler is one worth highlighting. The panellists showed that some HTAs do not include any adjustments for treatment switching, whilst adjustments can sometimes be incorrectly applied. It reinforced the idea that we need to learn more about these methods, to be able to apply them in practice and critically appraise them.
Next up in #ISPORBarcelona: Adjusting for post-randomisation confounding and switching in trials in room 117 (P1). This is a super important topic and source of frequent discussions in NICE appraisals. Looking forward to hear the experts views 😀 pic.twitter.com/7Ps62LPxlA

The afternoon finished with the second session of the day on posters. Alessandro Grosso, Laura Bojke and I had a poster on the impact of structural uncertainty in the expected value of perfect information. Alessandro did an amazing job encapsulating the poster and presenting it live to camera, which you can watch here.
In tomorrow’s blog post, I’ll tell you about day 2 of ISPOR Europe 2018 in Barcelona. Tuesday was another big day, with loads of outstanding sessions on the key topics in HTA. It featured my very own workshop, with Rob Hettle, Gabriel Rogers and Mike Drummond on communicating cost-effectiveness analysis. I hope you will stay tuned for the ISPOR meeting round-up part 2!
