Medicines only work
when people
can take them.

Half of patients with chronic disease do not take their medicines as prescribed, and the burden falls hardest where research is thinnest. We train and fund researchers in low- and middle-income countries to find out why, and we publish what they learn openly so treatment works where it is needed most.

Non-adherence is one of the largest preventable problems in chronic disease

An estimated 125,000 deaths and $300 billion in avoidable healthcare costs occur annually in the United States alone because patients do not take their medications as prescribed.

Between 30% and 50% of patients with chronic conditions do not adhere to their prescribed regimens. Yet most programs treat every missed dose the same way, although the causes differ.

Knowing why a patient stops is what makes the right help possible. That evidence is scarcest in low- and middle-income countries, where chronic disease is rising fastest.

Intentional Non-Adherence (INA)
The patient chose not to

Driven by beliefs, distrust, perceived side effects, or calculated risk. Responds to motivational and behavioral intervention.

Unintentional Non-Adherence (UNA)
The patient wanted to

Caused by forgetfulness, complexity, access barriers, or system failures. Requires structural support and simplification.

MAP (Multidimensional Adherence Parameters) is the eight-item instrument TESSERA GRC is built around: a familiar 0 to 8 score plus an Architecture, Execution and Context profile. PEACS, a separate exploratory instrument, tracks longitudinal behavioral profiles.

Research capacity where the burden is highest.

We fund adherence research led by local investigators, publish what it finds openly, and work with communities to act on it. Three programs, one aim: evidence from the places that need it most, shared with everyone.

Program 01

TESSERA Research Grants

Full or partial funding for adherence studies led by graduate students and early-career researchers in low- and middle-income countries. Every grant includes full access to ATLAS for the study (donated in kind by Adherence Cartography), plus training and mentoring. Nothing to pay, ever.

How funding works →
Program 02

Open Normative Science

An open, citable reference for what adherence looks like by condition, country and population, so every study has a baseline to compare against. Every contributing site is credited. Volume 1 is in preparation.

About the publication →
Program 03

Community Programs

With local partners, we measure and improve adherence where care actually happens. Our first is ADHERE, a stroke-prevention adherence program in Ghana led by SASNET-Ghana with the Ministry of Health and Ghana Health Service, launching on World Stroke Day, October 29, 2026.

Research Funding

We fund studies, from data collection to publication.

Good adherence studies in low-resource settings usually stall on small, practical costs. TESSERA Research Grants fund those studies, in full or in part, and give every grantee full access to ATLAS so that local researchers can run their own studies and publish under their own names. Grants are funded by donations to the Foundation, and donors can also endow a named one-year fellowship that carries one researcher’s study from fieldwork to publication.

Who can apply

Graduate students and early-career researchers at institutions in low- and middle-income countries.

What grants cover

Full ATLAS access for the study, plus full or partial funding of study costs: fieldwork and data collection, participant travel, translation, ethics review fees and open-access publication.

How awards are made

The Foundation’s board reviews every application. Each award will be published on this site with the researcher, country and amount.

TESSERA

All three programs run through TESSERA, our research consortium. A tessera is a single tile in a mosaic: each researcher and site adds one, and together they form a picture of adherence no single study could show. Individual membership is free. See the mosaic →

An open, citable
global adherence norm.

The TESSERA Annual Normative Publication will be a peer-reviewed, open-access scientific reference that every researcher using MAP, PEACS, or MMAS-8 can cite. Published by the Scala Carta Foundation. Co-authored by consortium contributors. Freely available to all.

What the publication contains

Normative ranges your study can be measured against.

The TESSERA normative publication draws on the ATLAS Global Dataset, made available to the Foundation by Adherence Cartography for open science, together with data that sites contribute directly through the TESSERA template. It captures MAP Predictive Emergence (PE) scores and PEACS profiles across sites and countries. It answers the question every adherence researcher eventually asks: what is actually normal for this condition, in this region, in this population?

The TESSERA Normative Publication is designed to answer it at global scale, with every contributing site credited.

✓
Global MAP PE norms: Predictive Emergence score distributions (Architecture, Execution, Context) by condition, country, and demographic group
✓
PEACS phenotype prevalence: Optimal, Good, Moderate, Poor, and Critical tier rates per therapeutic area and OECD vs. LMIC classification
✓
INA vs. UNA rates: intentional vs. unintentional non-adherence stratified by condition, care setting, and region
✓
MMAS-8 reference distributions: full score distribution curves with percentile tables suitable for sample size calculations and benchmarking
✓
Open methodology: full instrument definitions, scoring formulas, data governance certification, and contributor attribution

How to earn co-authorship

Your data. Your name on the paper.

Every contributing site, whether its data comes through the ATLAS Global Dataset or the TESSERA template, has its investigators listed as consortium co-authors on the annual publication when they meet ICMJE authorship criteria, whatever their membership type. The minimum contribution threshold is 30 MAP assessments from a documented patient cohort.

Contribution requirements
▸ Minimum 30 MAP assessments in a single cohort, submitted via the TESSERA Normative Contribution Template
▸ Documented patient population (condition, age range, country, care setting)
▸ De-identified per TESSERA GRC data governance protocol
▸ ATLAS or paper-based MAP administration (TransPerfect certified translation required for non-English)
What contributors receive
✓ Named consortium co-authorship for contributors who meet ICMJE criteria, with DOI-linked attribution
✓ Acknowledgment in the publication for every other contributor
✓ TESSERA Normative Contributor credential badge on your member profile and CV
✓ Pre-publication access to normative tables for your own study benchmarking

🔎
A shared benchmark.

Most studies define their own baseline. TESSERA builds a shared one that any study can be compared against.

🌐
Multi-site, multi-country data.

Most normative references are single-site or single-country. TESSERA aggregates prospective clinical data from contributing sites in many countries, building toward a global adherence reference.

📝
Citable in grant applications.

A DOI-assigned, peer-reviewed normative reference can anchor the rationale section of any NIH, Wellcome, or Fogarty grant. Reviewers recognize a citable norm as scientific infrastructure.

Free for researchers.
Three steps.

Students, early-career and unfunded researchers apply once, at no cost. Researchers at institutions in low- and middle-income countries are considered for a TESSERA Research Grant in the same application.

1
Apply

Complete the application below: about ten minutes, with your institutional email and a short statement about your patients and your question.

3
Take part

Complete MAP certification, run your study, and contribute data to the normative publication. Co-authorship follows contribution, on the same terms for every member.

For universities, hospitals and health systems
