Guidance Total number of records submitted via the web tool (ie Stroke / All records (of any diagnosis) for patients who arrived at hospital TIA / Other) between 1 October 2012 and 31 December 2013 which were locked on the SINAP web tool by 21 January 2013. Number of stroke records submitted via the web tool As above, except that stroke was the diagnosis (as opposed to TIA/Other). Total number of records after cleaning (ie duplicate removals) Records assumed to be duplicates are those that have all of the following fields identical: hospital, date of patient arrival at hospital, gender, age and diagnosis. This may mean that some records that were not real duplicates are removed, but this is proportionally only a small number of those removed, whereas the vast majority will be duplicates. This has been identified as the most appropriate method for removing duplicate records. Percentage of records submitted included after cleaning The percentage represents the proportion of records included in the quarter 7 report after the data cleaning process, this is listed below as total records and stroke records.
