  • Validation of Read Codes for the Identification of Asthma in CPRDNissen et al. validated a set of Read codes for the identification of asthma in CPRD in 2017. Use of specific asthma codes alone for identification of asthma patients had a positive predictive value (PPV) of 86.4 (77.4 to 95.4). The algorithm with the highest PPV included a non-specific asthma code, evidence of reversibility testing, and prescription of medication (PPV = 90.7 (82.8 to 98.7)).nanF. Nissen, Morales, D. R., Mullerova, H., Smeeth, L., Douglas, I. J., and Quint, J.

They found that high PPV were possible using a variaty of methods; however, there was high heterogeneity in the methods used.nanF. Nissen, Quint, J.

Implementation

These codes will capture asthma ever, not just current asthma. These codes are not intended to be mandatory, but are to be used as a starting point for the identification of asthma in routine EHR. Each study may differ in the sensitivity and specificity of the coding required.

For those interested in further discrimination of asthma phenotypes, we refer you to Nissen et al. 2019.
