A new health service body is being launched which aims to act as a champion of the public and patients.
The new body will not deal with individual patient grievances
The Scottish Health Council replaces a network of 15 local health councils which were scrapped earlier this year.
The new organisation promises to have a weightier role in ensuring proper consultation with the public.
However, some health campaigners believe the council is not truly independent and will not take patient views into account.
Margaret Hinds, vice-chairwoman of the Scottish Health Campaigns Network Margaret Hinds, said she was sceptical about whether it could be successful.
She said: "As far as we can understand, the remit is nothing to do with patients and with the people.
"It is to do with looking at health boards and how they consult. How can this new health council look at the situation, look at all the health boards around the country without input from patients and without input from the population affected?
"An independent body ought to have been set up, they should be seen as totally independent and I don't think they are."
The council, which began work on 1 April but is officially launched on Tuesday by Deputy Health Minister Rhona Brankin, will not deal with individual patient grievances.
Advice to ministers
Instead, it will focus on ensuring that the public and patients can make their views known to health boards and that those boards take those views into account.
The council will also advise ministers on whether health boards have properly consulted the public on major changes to services.
If not, it can ask boards to carry out the consultation again.
The council will have a national office in Glasgow and a local office in each health board area, each with its own advisory council of up to 15 volunteers.
The council's chairman, Brian Beacom, has insisted that the body is independent and its members have been independently appointed.
He added: "The establishment of the health council is good news for patients and all those who want to see a health service in Scotland that truly listens to and learns from patients' views.
"Health services that listen and pay close attention to the people they serve deliver better care, and the Scottish Health Council will be monitoring health boards closely to ensure that this happens."
Ms Brankin said the body could play a key part in delivering a more patient-focused NHS at local level.
"From today, we will have a new process to deliver an NHS which actively seeks the views of patients and uses them to drive forward quality improvement," she said.
