  "validation_description": "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.

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.
