Over 7,000 people have complained about inaccurate medical records on the Mor Prom app, prompting the Public Health Ministry to pledge legal action against anyone deliberately entering false data.
The ministry also vowed to ensure affected people do not lose healthcare, insurance or other benefits because of erroneous records.
Public Health Minister Pattana Promphat said on Tuesday that any incorrect information would be corrected after verification, adding that authorities could determine whether patients had actually received treatment before records were used to confirm entitlements.
He stressed that Mor Prom merely displays information submitted by healthcare providers and was not the source of the errors.
Deputy Permanent Secretary Dr Sophon Iamsirithavorn said the ministry had received about 13,000 complaints through online and paper channels. After duplicate submissions were removed, nearly 7,000 complainants were confirmed.
Cases have been forwarded to provincial authorities and healthcare facilities for investigation, with an update expected on Friday.
Permanent Secretary Dr Somruek Chuengsamarn said preliminary findings suggested most cases stemmed from misunderstanding by staff entering data, combined with heavy key performance indicator requirements.
Suspected cases of deliberate misconduct remain limited and are being investigated with the National Health Security Office. Anyone found guilty will face legal action, he said.
Mr Pattana said the ministry would continue returning health information through the app while correcting inaccuracies and retaining original data in the back-end system for audit and verification purposes.
