This pilot randomized controlled trial found that DKA treatment protocols using different rates of fluid infusion were not associated with differences in MRI measures of sub-clinical cerebral edema. JC attendees agreed that while the results were thought provoking, this study was not sufficiently powered (n=18) to be considered practice changing.

Epi Lesson – Blinding of Treatment Allocation


Open label trials may be promoted as pragmatic trials but a lack of blinding to treatment allocation is a fundamental threat to internal validity. Blinding reduces ascertainment bias (the likelihood of differential assessment of outcome). It is not always possible to undertake blinding in a RCT. But a critical reader will ask whether it was possible to blind outcome assessors. Doing so mitigates some of the bias introduced by open label trials.
