The 10 year follow-up results of the TOPKAT trial of total (TKR) vs partial (PKR) knee replacement are out! Similar clinical outcomes, but PKR more cost effective.

Beginning Nov 1924, studies on the effect of lighting on worker productivity were performed at the Western Electric Hawthorn Plant. These were the basis for the concept of the Hawthorne Effect 1/2

The work provides accessible definitions of the core elements of an estimand which will help aid understanding and should ease the use of the estimand framework across the range of stakeholders 8/8

A new paper by @suziecro.bsky.social and colleagues will help in this regard. Working with public partners, they developed a practical tool to explain the attributes of an estimand in an accessible manner 7/8

However, the technical language around estimands makes it hard to discuss the concept with patients and public (and indeed with many researchers and clinicians). 6/8

Kahan et al provide a useful introduction to the estimand approach and to the different terms/approaches used: 5/8

We may want to know how effective the treatment was in all patients allocated to it (this is called a “treatment policy” estimand strategy); or only in those patients who received it as planned (called a “principal stratum” approach) or some other variation. 4/8

“Intercurrent events” are post-randomisation events (eg discontinuation of treatment or treatment switching) and the estimand describes precisely how these events will be handled in the analysis. 3/8

An #estimand is effectively a more precise specification of the research question(s) and how the treatment effect is to be estimated (hence estimand). It also specifically describes how so called “intercurrent events” will be handled in the analysis. 2/8

The term #estimand is now part of the technical language of trials - but it remains a concept that many find hard to understand. Recent work has aimed to make the term more accessible to researchers, patients & public 1/8

In the EVERDAC trial involving patients with shock, results for death at day 28 indicated that management without early arterial catheter insertion was noninferior to early catheter insertion. Full trial results and Research Summary: nej.md/3LmOO0D

The world’s largest and longest clinical trial in critical care, SuDDICU found a significant reduction in hospital-acquired infection in critically ill patients on mechanical ventilation, when given antibiotics preventatively before a new infection can develop.
