Stephen Teap, one of the patient representatives on the HSE's CervicalCheck steering committee, has said he is worried he is not being told the truth by the HSE, and wants to know why information is being withheld.
Speaking on RTÉ's This Week, Mr Teap outlined his concern that patient representatives were not informed about this latest communications failure relating to CervicalCheck.
On Thursday, RTÉ News revealed that around 800 women were not given the results of their smear tests because of a reported IT glitch.
Mr Teap said the HSE did not involve the patient representatives in these discussions, describing it as "unacceptable", adding that he now "has zero confidence."
"They are back to eroding of trust and massive steps backwards with this communications failure and secrecy"
Mr Teap said he never believed that the Department of Health only found out about the communications failure on Wednesday.
"It's now being reported they found out on 25 June. If that is true that means that when we sat on the steering committee on 26 June everyone around the table would have been fully aware of this issue but didn’t share it with the patient representatives or discuss it, which I find terribly concerning.
"These are the questions I need answered. Why was this not raised and why were we not included also?"
Two years ago this month, Mr Teap's wife Irene lost her battle with cervical cancer.
