The authors noted that the report is intended to complement a meta-analysis conducted by the Task Force in 2015. The report is broken down into the following sections:
- Patient Selection
- Clinical Experience and Training
- Treatment Setting
- Medication Delivery
- Follow-up and Assessments
- Efficacy of Longer-Term Repeated Administration
- Safety Measures and Continuation of Treatment
- Future Directions
“The rapid onset of robust, transient antidepressant effects associated with ketamine infusions has generated much excitement and hope for patients with refractory mood disorders and the clinicians who treat them. However, it is necessary to recognize the major gaps that remain in our knowledge about the longer-term efficacy and safety of ketamine infusions,” the authors wrote. “Although economic factors make it unlikely that large-scale, pivotal phase 3 clinical trials of racemic ketamine will ever be completed, there are several studies with federal and private foundation funding aiming to address some of these issues.
“It is imperative that clinicians and patients continue to consider enrollment in these studies when contemplating ketamine treatment of a mood disorder. It is only through these standardized clinical trials that we will be able to collect the data necessary to answer some of the crucial questions pertaining to the efficacy and safety of the drug.”
The authors also pointed to the value that a registry of patients treated with ketamine could offer for the field.
“Ketamine provides new excitement for psychiatry and offers the hope of much-needed novel and perhaps more effective treatments,” Charles Zorumski M.D., and Charles Conway, M.D., of Washington University School of Medicine, wrote in an accompanying editorial. “The consensus statement by Sanacora and colleagues, however, provides a sobering cautionary guide, especially as we move toward attempting to sustain the gains achieved by acute doses of ketamine. This consensus statement will not be the final word on this topic, and similar considerations will be needed for other novel treatments.”
