We help clinicians and health systems deliver timely, safe, evidence-based care—through consultation, education, and hands-on implementation support, so people get the right care from their own providers.
Building a network of clinicians and health systems to expand access to evidence-based TRS treatment
TRS ACCESS supports clinicians and health systems caring for people with treatment-resistant schizophrenia (TRS). ACCESS reflects how we work through Advocacy, Clinical Consultation, Education, and Support Services.
We help health systems and providers expand safe, effective use of clozapine—the only FDA-approved medication for TRS—and long-acting injectable antipsychotics.

TRS is common, but clozapine remains rarely used.
Across 50 studies, the estimated prevalence of TRS was 36.7%.
Schizophrenia Research, 2023Based on health records from 11 U.S. health systems.
Journal of Clinical Psychiatry, 2024Use was below 0.10% of the total population, while an estimated 0.20% may be eligible for clozapine.

A lighthouse is a beacon of hope in a sea of uncertainty.
Clozapine is proven to be the most effective treatment for TRS, but many people never receive it. The TRS ACCESS Network exists to close this gap by supporting earlier, safer, and more consistent use of clozapine and other best-practice interventions.
We partner with clinicians, clinics, and health systems to:
Abigail Donovan, MD explains the importance improving health outcomes
Measuring and improving outcomes for people with TRS can transform lives and healthcare delivery. Our focus on outcome-based care helps ensure that every intervention leads to meaningful improvements in well-being and recovery.
