“We know that an enormous percentage of chronic mental illnesses begins in adolescence and early adulthood. There is some evidence that psychosis itself is toxic to the brain and there is a very robust association between the duration of untreated psychosis and outcomes,” says Dr. Dixon, who is Director of the Division of Behavioral Health Services and Policy Research within the Department of Psychiatry at Columbia and Director of the Center for Practice Innovations at the New York State Psychiatric Institute.
In this role, Dr. Dixon oversees activities for the New York State Office of Mental Health in implementing evidence-based practices for persons diagnosed with serious mental illness. She is also leading the innovative program, OnTrackNY, a statewide initiative designed to improve outcomes and reduce disability for the population of individuals experiencing their first episode of psychosis. Dr. Dixon is supported in these efforts by Co-Directors Ilana Nossel, MD, Medical Director of OnTrackNY, and Iruma Bello, PhD, Clinical Training Director of OnTrackNY. Through this program, young people with early psychosis receive help from Coordinated Specialty Care teams that work with them to achieve their goals for school, work, and relationships.
Statewide programs are coordinated by OnTrack Central at the Center for Practice Innovations and regional field offices of the Office of Mental Health. OnTrack Central also provides training and technical assistance to program teams based on OnTrackNY’s model of Coordinated Specialty Care.
Dr. Dixon’s dedication for improving the lives of young people with debilitating mental illness stems from personal experience – her brother has schizophrenia. He began showing signs of psychosis while they were both in medical school and was unable to graduate. She believes that if her brother had had access to an early intervention program when he was first getting sick, life might have been very different for him.
“We are very tuned in to shortening the pathway to diagnosis and decreasing the duration of untreated psychosis,” says Dr. Dixon. “We don’t want teenagers hearing voices or having paranoid delusions while trying to manage high school with no one understanding their behavior or intervening to help. The OnTrackNY program is quite different from traditional schizophrenia treatment models, which have historically focused resources on patients who already have chronic and severe disabilities.”
To address this compelling need for early intervention, Dr. Dixon initiated a study to assess outcomes of adolescents and young adults who are enrolled in OnTrackNY’s Coordinated Specialty Care program. Data is also being aggregated with similar programs across the country through the Early Psychosis Intervention Network (EPINET) data repository. The intervention study was borne out of the Recovery After an Initial Schizophrenia Episode (RAISE) grant from the National Institute of Mental Health that was awarded to the Columbia Department of Psychiatry.

- A significant decline in inpatient visits from the pre-OnTrackNY enrollment period to the predischarge period
- No significant change in inpatient visits in the first 6 months after discharge
- Inpatient visits remained significantly lower than before OnTrackNY enrollment
- Similar patterns were observed for inpatient days and ER use
The study, which is the first of its kind in the country to examine post-intervention outcomes of participants in Coordinated Specialty Care programs, found a significant decline in inpatient hospital visits from the pre-OnTrackNY enrollment period to the predischarge period.
In an earlier study, Dr. Dixon and her colleagues in the Department of Psychiatry at NewYork-Presbyterian/
Clinicians provided data at baseline and quarterly up to one year related to symptoms, occupational functioning, social functioning, education and employment status, and psychiatric hospitalization rate. Results, which were published in the August 1, 2018, issue of Psychiatric Services, were encouraging:
- Education and employment rates increased from 40 percent to 80 percent by six months
- Hospitalization rates decreased from 70 percent to 10 percent by three months
- Improvement in scores on the Global Assessment of Functioning continued for 12 months
The study further indicated that demographics and baseline education predicted education and employment outcomes. With this in mind, the authors recommended that Coordinated Specialty Care teams should strive, in particular, to support the occupational goals of individuals at increased risk of not engaging in work or school, including male participants and participants from racial and ethnic minority groups.
These studies and others associated with OnTrackNY’s Coordinated Specialty Care program provide clear evidence to support its multidisciplinary approach. Under Dr. Dixon’s leadership, OnTrackNY has expanded to 22 sites in New York State. With the recognition of the importance of reducing the duration of untreated psychosis, similar Coordinated Specialty Care programs have been expanding across the country, increasing from 12 sites in 2008 to 340 sites in 2020. Long-term follow-up studies are underway to understand whether the benefits of OnTrackNY extend beyond the two years that most young adults are enrolled.

“We are in a new phase in the world of schizophrenia care,” says Dr. Dixon. “When I was trained, it was an illness that in some ways patients were sentenced to a lifetime of disability. Because of developments in science, advocacy, policy, and the participation of individuals with lived experience, we are now living in a time of hope.”
