Once your practice has enrolled, data will be automatically extracted from your practice’s EMR – approximately every 3-6 months – and the DPT will be updated accordingly. If there are any changes to the type of data collected or uses of data, all practices will be informed of the changes and we would ask for your renewed consent to participate. At any time, practices can choose to end their participation in the study. Individual patients at participating sites can also opt out of CPCSSN and no data will be collected on these individuals.
