A health board was warned about ventilation issues years before they delayed the opening of new hospital buildings, an NHS review has revealed.
Last month it was announced problems with ventilation systems were among issues contributing to delays at two Aberdeen hospital buildings.
But a review shows “multiple concerns” about the issue were raised in 2020 and “do not appear to have been addressed”.
NHS Grampian said it was addressing the points raised by the review.
The health board added that many of the issues raised by NHS Scotland were due to changes in guidance and processes in the wake of problems with new hospitals in Glasgow and Edinburgh.
The Baird Family Hospital and Anchor Centre were both meant to open in 2020 but a series of delays mean the overall project cost is now £261m – £98m more than the original estimate.
A review of the Anchor Centre project, which will provide services for haematology and oncology patients, was completed by NHS Scotland in March as part of work to ensure infection prevention and control are a key consideration in building new hospitals across the country.
The review found the project had three “significant” issues to address, including ventilation and drainage, and 15 more issues categorised as “major”.
The report, released to BBC Scotland under freedom of information laws, shows that a previous NHS review produced in September, 2020 “identified multiple concerns in relation to the development of the ventilation strategy that, from the evidence presented, do not appear to have been addressed”.
