A more thorough discussion of the costs and benefits of continued treatment could help doctors and families better judge whether the care would be helpful or futile, but Wenger said the parties involved are often reluctant to have that type of talk when a loved one lies dying.
"It means having a lot of hard conversations. It means talking about what the course of care should be if the surgery doesn't work or if the patient doesn't get better," he said.
"It's much easier to focus on the positive only," he added. "If those conversations don't happen, it's the family left to decide what to do, never having had the opportunity to talk with the patient about it."
