  3. bIncludes ‘New’ and ‘Unplanned Return’ attendances only at A&E, excludes those who are ‘Recall’ or ‘Planned Return’. For Scotland based on A&E sites which returned episode-level information for at least one of the following: ICD10 Diagnosis code (R098/R068/R062/R060/R05X/R05/J46X/J46/J459/J458/J451/J450/J45/R688/R69X/R69/Z825/J21/J210/J211/J218/J219/R06/R09/R092) OR Diagnosis free-text extracted from “Wheez”/“Asthma”/“Ashtma”/“low” AND “sats”(“chest” AND “tight”) AND (“SOB” OR (“short” AND “breath”)). However, most Health Boards use a pick list/disease code from ICD-10 codes, these are usually mapped from diagnosis text where a pick list has been used. NHS Tayside and NHS Orkney only submit high-level diagnosis codes (comprises about 6 % of total attendance), thus have been excluded here. Thus, figures presented here will be an underestimate of the true number of attendances to A&E for Scotland
  4. cICD-10 codes J45/J46 as primary reason for care. For Wales, the first non-R or Z code in day-cases were also used additionally. R codes refer to “symptoms” and Z codes to “factors influencing health status and contact with health services”
