“Can hospice patients have surgery?”

This is quite a complex issue. Surgery in any field boils down to risk to benefit ratio. It’s important to understand that hospice and DNR (Do not resuscitate) status does not mean do not treat. Hospice is all about preserving the quality of life of a patient as they take their final steps from life to death. If there is something in particular that is making him miserable or uncomfortable and it is straightforward, I suspect that surgical intervention is an option as long as the risk benefit ratio is in his favor. This is a very tricky topic, especially for surgeons because outsiders looking in may not understand the thought of going to surgery with somebody who might be terminal. With that being said, your family and those that are acting in the best interest of your grandfather as well as your grandfather Should have a say in what is done. Praying for peace for both your family as well as your grandfather.

It depends on the condition of their hospice. Sometimes one must come off hospice for treatment. Sometimes that treatment is within bounds of the hospice arrangement

Depends on the surgery, some surgeries are palliative in nature. Would really depend on the surgery and the individual/family goals of care.

It depends on why they are in hospice & what there current condition is.

Absolutely! You need to understand the scope of the treatment of a patient in hospice: toward making the patient more comfortable, getting rid of the pain if possible, etc. it would be unreasonable though to operate on a non-blocking colon cancer or do a colonoscopy in a patient that is not expected to survive more than six months as a hospice patient is. However if the tumor is obstructing, a colostomy to relieve the patient is more than indicated. I would not put a feeding tube in a hospice patient.

It is exceedingly rare that a hospice patient would require a surgical procedure (DNR would have to be reversed, etc.)

Impossible to really weigh in on this without knowing the details here

Yes.

If the goal of surgery is to improve his quality of life, then surgery on hospice is a possibility.
