A takeover of two Greek diagnostic networks has exposed 3,184 imaging reports left in a digital queue, including 67 marked urgent, without a recorded alert to the doctors who requested the scans. The findings, from a review ordered after the deal closed in July, raise questions about how the company managed high-priority results across its clinics.
The Health Services Inspectorate said its review covered records from 2023 to 2026 at 23 centres run by Orvantis Clinics, which took control of Kallisto Scan Network in a €126 million (about $146 million) transaction. Of the reports in the queue, 417 had remained there for more than 30 days, the regulator said.
Audit tracks the hidden queue
The inspectorate’s 9 September notice says its auditors compared reporting-system logs with delivery records and found no documented acknowledgement for 67 results classified as urgent. It has not said that the reports were missed by patients or that the delays caused harm. The agency has ordered Orvantis to contact affected patients and doctors and submit a full account by 30 October.
Liliána Szabó, a retired school administrator in Patras, said she waited 23 days for a report after a routine scan in May. It appeared in the clinic’s patient portal, she said, but her family doctor received no alert; she called the clinic after asking when the result would arrive. “I thought the report had gone straight to the doctor,” Szabó said.
Mustafa Ram, a health-data specialist who reviewed the inspectorate’s published figures, said a portal entry was not a substitute for the direct notification required under the clinics’ urgent-result procedure. “The key issue is not whether a file existed, but whether the person expected to act on it knew it was there,” he said.
Orvantis said the queue formed during the transfer of records between two different reporting systems and that patients could access their results through secure portals. Spokesperson Leonard Vasile said the company had found no evidence that a patient was harmed, and that its clinical teams had reviewed all 67 urgent cases. The company said it was working through the wider backlog and would meet the inspectorate’s deadline.
Who controlled urgent results
The takeover brought the two networks under one management team, but their clinics had used separate software and different routines for notifying doctors. The regulator’s notice says a shared system was introduced after the sale; during the transition, some reports were filed under a status labelled “awaiting acknowledgement”. The company has not explained how long managers knew that the queue was growing.
The inspectorate is examining whether staff had a clear route to escalate urgent cases and whether local clinic managers could see the full queue. A second audit will check a sample of reports against call records and patient files. Orvantis said it had added a daily review of urgent results and was retraining staff at all 23 centres.
The case has drawn attention to a practical risk in consolidating private diagnostic services: reports can be available online yet still fail to reach the clinician meant to follow up. The inspectorate says it will publish its final findings after the October deadline. It can require corrective measures, but has not announced a penalty.
