The Human Tissue Authority Code of practice 3: Post-mortem examination outlines all the necessary guidance.
Consent is a process and must not be rushed. Assist parents in understanding the post-mortem consent form – no parent ever considers this may be a choice they will have to make. Ensure you are familiar with the form. In a consented post-mortem, parents’ permission needs to be given for any tissue or organs to be retained for any purpose.
When requesting a post-mortem examination, explain to parents that it will be carried out respectfully. Parents need to know it will not usually affect their child’s face, hands or feet.
If a coroner orders a post-mortem when a death is sudden and unexpected, or of unknown cause, this is a legal requirement and parents are not asked for permission. But they need every bit as much support and information as to why the procedure is required, the likely timescales involved, and how the findings may help them understand why their child died. If possible, give the name of the pathologist and explain where their child will be taken for the post-mortem examination. Parents are likely to want to know the timescales involved and may ask about the possibility of seeing their child afterwards.
If parents do agree for any tissue or organs to be retained, you should recognise that every donation is a gift.
