Make a wish is fantastic and most nurses can put the family in touch with them, i know specialist oncology at UHCW do this! They act as an advocate for the patient and families needs and tailor the support they need to suit each family. Even if this is outside of your knowledge or accessibility as a nurse, the specialists in paliative care, childrens care or oncology will have the means to do so, so often just the referral to the wider MDT is needed.
