If an elderly person is lost, the caregiver is busy searching for him/her and has to call the police for help, so he/she must feel worried and anxious. It is recommended that caregivers should prepare a tracing leaflet for elders who are at risk of getting lost, including full and half body photos, physical characteristics, medical history, clothing at the time of loss, daily routine, emergency contact information, etc., so that the leaflet can be handed over to the police for follow up in the event of loss, which will help to speed up the process of tracing the elders.
