About this trial

This observational protocol is intended to provide long-term follow-up data on patients initiating or continuing treatment with either Spravato® or IV ketamine. This can provide us information on the patient acceptability and satisfaction, patterns of use, long-term effectiveness, and safety of the two approaches.

This 5-year, 6-site study will enroll 450 total patients. The sites will comprise 3 academic medical centers and 3 community psychiatric practices.
