Dad's death helps national expert evaluate end-of-life care

Since 1991, end-of-life care has seen significant improvements in palliative care and hospice availability. Timothy Quill's father's death provided a unique opportunity to illustrate the good and bad in end-of-life care, highlighting the need for consistent availability of care options.

Questions raised on DNR orders and shorter hospital stays

A Northwestern University study found that death rate after hospital discharge increased up to 72 percent for patients with DNR orders. Despite this, the researchers suggest that shorter lengths of stay can be achieved without compromising patient health through improvements in therapies and end-of-life care.
