KRI 3-Day Intensive Training Course for Clinicians

Yale-National Institute of Mental Health "Standard"

Ketamine Infusion for Mood Disorders  

Ketamine Infusion Therapy for Mood Disorders is the only coordinated and comprehensive training program in the use of ketamine-based therapy for clinicians and other practitioners in North America. The program is rigorous and meets or exceeds the American Psychiatric Association consensus recommendation for ketamine therapy and the American Society of Anesthesiology guidelines for monitoring and airway management requirements.

The Ketamine Infusion Therapy for Clinicians program is comprehensive. Its teaching content is not restricted to theory or academic interest but is grounded in almost 35 years of active clinical ketamine infusion practice. We are dedicated to ensuring that every practitioner who successfully completes our training is competent in this new discipline and able to incorporate it into practice.

Our training course specifically trains clinicians to safely and effectively administer the standard ketamine infusion protocol developed at Yale in 1994-2000 and is currently used by the National Institute of Mental Health and other major institutions around the world.

We believe that there is a tremendous need for qualified, medical professionals trained to provide patient-centered, safe, effective ketamine therapy for mood disorders. Our intensive program provides clinicians with the necessary skills, understanding, and knowledge essential to administer a superior and optimized ketamine infusion to their patients in an office or outpatient setting. The program covers all aspects of ketamine therapy that have practical clinical applications today and for the future.

Yale-NIMH Standard Ketamine Infusion for Mood Disorders

Our Program Graduates have met the necessary training requirements to:

— Understand the rationale for using ketamine infusion therapy for mood disorders and the mechanism of action of ketamine as an antidepressant.

Gerald W. Grass, MD - Course Founder and Director

Gerald W. Grass, MD, began utilizing ketamine in the treatment of chronic pain and depression in 1998 and has since pioneered the development of the RESTORE Infusion and has established Ketamine Infusion Training Program, the first international training program for physicians to alleviate treatment-resistant mood disorders and intractable chronic pain rapidly.

Dr. Grass has more direct-patient clinical experience providing ketamine infusion therapy than any other physician in the United States.  His work treating injured soldiers returning from Iraq and Afghanistan with complex pain, depression, and PTSD issues led to the development of the RESTORE infusion. He has presented his breakthrough accomplishments in regional and national meetings and conferences and to other physicians and governmental organizations, including the Veterans Administration and the Department of Defense.

Dr. Grass developed the RESTORE Infusions over 20 years as an improvement of the regular ketamine infusion.  The ultimate goal was to make ketamine-based infusion therapy as effective and long-lasting as possible. Today, the RESTORE infusion is regarded as a "gold standard" in ketamine-based treatment.

In addition, to developing RESTORE, Dr. Grass is a widely published author and lecturer who has numerous academic publications, including peer-reviewed articles, educational presentations, abstracts, and book chapters. He has taught at some of the most prestigious academic and research institutions in the country, including Yale School of Medicine and the NYU-Mount Sinai Medical Center.

Dr. Grass has more direct-patient clinical experience providing ketamine infusion therapy than any other physician in the United States.  He is sought out by major medical centers, research institutions, and other physicians for his expertise and experience in the area of ketamine therapy.

We bring together a multidisciplinary international collaboration in the field of ketamine-based therapy, bringing together scientists, clinicians, healthcare providers, and policy makers to stimulate and support the study of ketamine and to translate that knowledge into improved relief worldwide.

The Ketamine Research Institute was founded to continually improve and perfect ketamine treatment for an expanding range of chronic illnesses. After devoting almost 2 decades to the clinical use, research and development of this innovative therapy. We are a very specialized center devoted exclusively to ketamine treatment, clinical research, education and training physicians worldwide in the use of ketamine. We have developed the first and most comprehensive educational training program for physicians in the use of ketamine-based therapy.  More than that, we have established an international multidisciplinary collaboration initiative with centers in Australia and Europe to share knowledge and expertise with physicians on the cutting-edge of ketamine therapy.

Additionally, to ensure that all of our certified ketamine centers provide treatment in the most effective way and in a safe manner, the Ketamine Research Institute, in collaboration with our partners, has and developed the first International Standards for Ketamine Infusion Centers.  Our goal is to ensure that you have the best possible opportunity to improve with ketamine infusion therapy.
