The whistle-blower at the centre of an abuse investigation at a care home near Bristol is setting up a website to help people in a similar position.
Undercover research by the BBC Panorama programme revealed cruel treatment of patients at Winterbourne View hospital.
A former senior nurse at the home, Terry Bryan, earlier reported incidents to managers and the Care Quality Commission but said nothing was done.
He said he now wanted to help people like him to "be believed".
"They need to know that the [whistle-blowing] process is going to work in their favour," he said.
"I need to say to people, 'you can come through the other end'.Procedure reviewed
"If there's anything I can do that would help other people blow the whistle in their area, then I will do it."
He said he was in the process of setting up a resource website for would-be informants seeking advice.
Since the programme was screened, four people have been arrested and released on police bail.
The hospital's owners, Castlebeck, have apologised and suspended 13 employees.
The company has launched an internal investigation into their whistle-blower procedures and are reviewing the records of all 580 patients in its 56 facilities.
The vulnerable patients filmed by Panorama have been moved to safety.
The Care Quality Commission has also apologised for not acting on Mr Bryan's report.
