We recently received a query from a reader of our article , about the ICD-10-based definitions used to define the "chronic obstructive pulmonary disease / asthma" group of index admissions. Prompted by the query, we detected an error in the way the definition of this group, as well as the "acute coronary syndrome" group are described in the printed version of our article, which we wish to correct.
The printed version of the article describes chronic obstructive pulmonary disease / asthma as composed of ICD-10 codes J44.0-45.9. This should have read: J40.0-J46 (i.e. diagnostic codes relating to Chronic Obstructive Pulmonary Disease, chronic bronchitis, emphysema and asthma), as well as J12.0-J18 (i.e. diagnostic codes relating to pneumonia). We have included asthma and pneumonia in the definition of this group because, based on experience, we felt that in adults over 50 who are admitted to hospital a primary diagnosis of either asthma or pneumonia is very likely to either represent miscoding of COPD for (asthma or pneumonia), and/or an exacerbation episode of underlying Chronic Obstructive Pulmonary Disease. We include the exact composition of this group, by diagnostic code in Table 1.
Similarly, in the printed version of the article the group of "acute coronary syndrome" is defined as I20.0 and I21.0-9. This should have read: I20.0-9 (i.e. angina), I21.0-9 (acute MI) and R07.0-9 (i.e. "non-specific pain in throat or chest"). Again we have decided to include non-specific chest pain along with angina and MI, due to potential for miscoding and/or true co-morbidity (of non-specific chest pain with acute ischaemic heart disease presentations). The exact composition of codes used for the "acute coronary syndrome" group is included in Table 2.
