When my Mother was dying of cancer, she was in several hospitals and finally in a hospice.
We would ask how her day was and who had visited her, and she would reply: “My day was not good and no one visited me”. We knew this was not true, so we decided to place a diary by her bed, with a large label, asking visitors to put their name, date of visit, how she was doing, what they talked about etc.
When we visited, we were able to see at a glance who an when she had visitors and how she looked to them. That allowed us to have a ore meaningful conversation with her and the doctors were able to gain a greater insight into her wellbeing through the visitor notes.
When my Mother passed away, we left a legacy to the hospitals, of diaries for all patient families to use.
