Description
Public Health Scotland (PHS) and NHS boards work closely to ensure that published waiting times information accurately reflects locally held data.
During 2013 and 2014, all NHS boards gradually moved to a new Treatment Time Guarantee (TTG) compliant extract.
This change, compounded by a limited time period to test new extracts with redeveloped PHS national data mart, led to new data quality issues that were subject to further investigation.
