For HEDIS 2021, HEDIS measure data will be collected in the new format through the updated IDSS system. With this new format, the data elements under the measures will be more relational, modular, reusable and meaningfully named and structured. Measures with different stratifications will have data points gathered in groups such as age, gender and socio-economic status.
