Q. I have list of cholim whose names I insert in Shmone Esrei.. How often do I need to ask if the people should still be on the list? What if I can't contact the person who gave me the name? Are there any criteria for adding someone's name to the list?
I thank the Rabbi for his time.
A. Usually shuls that recite a Mi Sheberach for the ill, either during the Torah reading, or after saying a chapter of Tehilim after davening daily, have an established tradition of renewing the list of the ill on a weekly, by-weekly or even a monthly basis.
The people requesting the service, usually know when they need renew and reapply again
You may also tell the people that ask you to pray on their behalf, the period that b'n you are planning to daven for them.
