An older people scheme, which gave practices £50 every time a patient signed up, has seen increased numbers of people dying in the place of their choice.
Ipswich and East Suffolk clinical commissioning group (CCG) had faced criticism for the plan.
Critics claimed the project was a money-saving scheme, to free up hospital beds as patients could opt to die at home.
But the plans are to give patients a dignified death, the CCG has said.
Now 52% of patients are dying in the place of their choice, thanks to the end-of-life plan.
Annette Villis from St Elizabeth Hospice was working with the CCG to roll out the plan.
She said around 6,000 patients in Suffolk had chosen to use it.
“The hospice has helped initiate the system with its patients here and those we care for at home and we are now seeing patients coming into our services with them,” she said.
The end-of-plans started in east Suffolk in 2011 before being rolled out to Ipswich practices during 2012.
