HDAS has built up a large amount of saved data, which has a potential impact on performance. Please review your saved search strategies and saved results and delete any that you don’t need any more, or export those that you do. You can export saved results in a variety of formats to save outside HDAS. From 1st August, NICE Evidence Services will automatically delete any saved results that are more than 2 years old.
