Where a wildcard is displayed, the Read Code is filled to 5 characters with ‘%’ When implementing a search for the Read Code, only the non full-stop values should be used in the search, For example, a displayed Read Code of c1...% should be implemented as a search for c1%, i.e. should find c1 and any of its children. Where a of read codes are displayed, the Read Code is filled to 5 characters with range full-stops. When implementing the search, only the non full-stop values should be used in the search, For example, a displayed Read Code range of G342. G3z.. should find – all codes between G342 and G3z (including any children where applicable). Note: ranges only apply to Read V2 and not to CTV3 codes. Clinical data extraction criteria These are the data items to be exported from the clinical system for subsequent processing. The information provided to enable the initial export is as follows: Column Content Field Number Identifier of extract columns Name of data item. Each name will have a suffix, e.g.: _DAT for dates Field Name _COD for clinical codes _VAL for values _AGE for patient age If the field relies upon code clusters, the cluster reference IDs Code cluster are specified in the cluster’ column (see for more ‘Code information). The qualifying criteria specifies any limits applied to the field. Typically these relate to dates and refer to the or ‘EARLIEST’ occurrence of an event; however the qualifying ‘LATEST’ criteria may also relate to values associated with the data Qualifying criteria being extracted for the chosen field. The statement is used to select every occurrence of “ALL” codes or dates. It selects an array of instances, of which there may be more than one for each patient. The description gives a textual explanation of ‘non-technical’ what is required to be returned for the field. Non-technical descriptions are provided as supplementary Description information to assist non-technical readers (e.g. GP practice staff, area teams, etc.) to interpret the logic.
