'Outdated' computer systemspublished at 16:04 Greenwich Mean Time 30 January 2019
Computer systems in the Welsh health service are "outdated" and failures are having a "negative impact" on patients, according to the report.
The inquiry questioned the "competence, capability and capacity" of the body that looks after IT, the NHS Wales Informatics Service (NWIS).
There were 21 systems outages in the first half of 2018, according to the public accounts committee.
"As we begin scrutinising one area, we find that other, equally serious questions arise elsewhere," the report said.
"As a consequence, we are anxious that our scrutiny has merely scratched the surface of NWIS' problems."
