This out of hospital, French randomized controlled trial found that when family members were given the option of viewing ongoing resuscitation they had less PTSD at 90 days with an adjusted OR of 1.7 (95%CI 1.2 to 2.5) than those with usual care. JC attendees appreciated the overall design and execution of this challenging study and felt that this supported current standard of care to have family members present during ongoing resuscitative efforts.

Validation of Measurement Tools
When investigators state they used a validated tool, this means that the tool has been evaluated to determine whether it accurately measures what it aims to measure. Two important components of validity include face validity (experts endorse that the tool is logically designed to measure a given construct) and content validity (the tool comprehensively includes all possible dimensions of a given construct). These are distinct from reliability which indicates that the tool consistently measures a given construct (usually by more than one user e.g. inter-rater reliability)
