Doctors attending the funerals of their patients: Good idea or bad?

Although in many cases it seems like the health care trends are leaning towards less personalized care, some doctors are trying to go in the other direction instead -- by attending the funerals of their patients. Although it can be a slightly controversial idea (especially if the family wasn't necessarily satisfied with the care), in many cases having the doctor at the funeral can be a positive experience for both sides. The doctor can get a completed picture of the client and have the opportunity to support the family, and the family can build a stronger relationship with the doctor and feel affirmed.

Do you think it's a good idea? Should all doctors try to to make themselves available and open to this idea?
