As a clinical negligence solicitor, I hear this from my client's all the time!
Many of my clients have suffered Post Traumatic Stress Disorder (PTSD) as a result of the negligent events. They suffer nightmares and flashbacks of the events and the thought of returning to the “scene of the crime” is overwhelming. The sights, sounds and smells of a hospital can bring back horrific memories.
Frequently they will avoid interaction with medical professionals wherever possible. They will also worry about family and friends coming into contact with medical professionals and what could go wrong.
Even those who do not suffer PTSD will often take significant steps to avoid coming into contact with medical professionals.
I would support anything which offers traumatised patients an opportunity to reduce the likelihood of suffering further trauma when seeking medical assistance.
