This project will evaluate the maturity of the currently drafted CDS Hooks hooks and ballot hooks based upon their maturity. CDS Hooks hooks follow the prescribed maturity model defined in the CDS Hooks specification: https://cds-hooks.hl7.org/1.0/#hook-maturity-model . The specific hooks under consideration include all currently published or proposed CDS Hooks (e.g. order-select, order-sign, encounter-start, encounter-discharge and appointment-book). Following ballot, if appropriate per HL7 feedback, the outcome of this PSS will be an updated publication of the hook definitions currently described here: https://cds-hooks.hl7.org/ Sponsoring WG: CDS Co-sponsors: none Interested: CQI
