TESSERA GRC is the world's first clinician-led adherence science consortium. We fund scholarships, govern research standards, connect investigators across 60+ countries, and build the evidence infrastructure that makes precision adherence science possible everywhere — not just where funding flows.
An estimated 125,000 deaths and $300 billion in avoidable healthcare costs occur annually in the United States alone — not from treatment failure, but from patients not taking their medications as prescribed.
Between 30% and 50% of patients with chronic conditions do not adhere to their prescribed regimens. Yet most interventions treat all non-adherence the same — a critical error with measurable consequences.
Scala Carta Foundation exists to change that by funding and disseminating the research infrastructure that makes precise, behavioral phenotyping of non-adherence possible at scale.
Driven by beliefs, distrust, perceived side effects, or calculated risk. Requires motivational and behavioral intervention, not reminders.
Caused by forgetfulness, complexity, access barriers, or system failures. Requires structural support and simplification.
MAP (Multidimensional Adherence Parameters) is the validated instrument that distinguishes INA from UNA, generating PEACS phenotypes that drive targeted intervention. Developed by Philip Morisky, MAP is the scientific core of TESSERA GRC.
Scala Carta Foundation funds researchers, stewards global data standards, and connects clinicians and scientists across 62+ countries. TESSERA GRC (Global Research Consortium) is the program through which this work is organized. ATLAS is the data collection platform members use at their tier.
Full TESSERA membership fee waivers for graduate students and researchers at institutions in World Bank-classified low- and middle-income countries. No external funding required. No cost, no barrier.
A data-exchange pathway for researchers whose institutions restrict external platform subscriptions. Submit standardized aggregate MAP data and receive full instrument access, a formal letter of permission, and TESSERA authorship credit.
A live collaboration board for the global adherence community. Post active studies, call for international co-investigators, announce grant opportunities, and discover matching cohorts across 40+ countries. Research Affiliate tier and above can post.
Formal partnership agreements with universities, health ministries, pharmacy networks, clinical research organizations, and pharmaceutical manufacturers. TESSERA partnerships establish data-sharing frameworks, co-publication terms, and advisory governance roles.
TESSERA governs the world's only multi-site, multi-country MAP normative dataset. Members contribute aggregate data; TESSERA publishes validated phenotype benchmarks under open-access terms that any researcher can cite, replicate, or build on.
TESSERA GRC establishes the governance, risk, and compliance framework for how MAP data is held, attributed, and shared across jurisdictions including the EU (GDPR), UAE (PDPL), and US (HIPAA). Institutions joining TESSERA inherit this framework — they do not have to build it themselves.
A no-login, browser-based kiosk tool for pharmacies, mobile outreach programs, and telehealth services to administer MAP assessments outside of clinical settings. Available to Institutional Partner members and above. Assessments contribute to the global adherence dataset under TESSERA data governance.
Every TESSERA member receives a formal credential tied to their tier and active membership. These credentials appear in publications, thesis acknowledgments, grant applications, and researcher CVs — and are verifiable against the TESSERA member registry.
The inaugural TESSERA Summit will convene member institutions, researchers, and industry partners for the first global conference dedicated exclusively to behavioral adherence phenotyping science. One agenda. One network. Every major contributor to this field in the same room.
TESSERA membership includes access to the ATLAS platform at every tier. Members who want standalone platform access without consortium membership can get a workspace key at atlas.adherence.cc.
The global burden of medication non-adherence falls disproportionately on low- and middle-income countries, where chronic disease rates are rising fastest and research infrastructure is thinnest. TESSERA GRC was designed with this asymmetry in mind.
Through our LMIC Grant Pathway and Research Contribution License (RCL), researchers at qualifying institutions can access full TESSERA membership, including MAP instrument access and co-authorship on normative studies, at no cost.
Donor support is what makes this possible. Every contribution to Scala Carta Foundation directly funds the participation of a researcher who would otherwise be excluded from the global evidence network.
Full TESSERA membership fee waiver for researchers at institutions in World Bank-classified low- and middle-income countries.
Researchers anywhere may contribute normative MAP data in exchange for full consortium membership, including institutional access to MAP scoring and co-authorship eligibility.
Every tier grants consortium standing, data governance coverage, and a TESSERA credential. The tier you choose reflects the scope of your engagement — from a single researcher earning their first publication credit, to a health system contributing to global normative science, to an industry partner accessing population-level real-world adherence data. All tiers include ATLAS platform access for data collection.
Post active studies, call for international co-investigators, and discover matching cohorts across 40+ countries. Research Affiliate tier and above can post; all tiers can browse and respond to open calls.
