Information on waiting lists is collected centrally by means of a quarterly census which records how manypatients are waiting on the census date, but does not record information on additions to a waiting list between census dates.Figures for the deferred waiting list, by NHS board and NHS trust, for each census date since 30 June 1999 are available on the NHSScotland Acute Activity, Waiting Times and Waiting Lists website at http://www.show.scot.nhs.uk/isd/acute_activity/hb1.asp?
