Project ECHO (Extension for Community Healthcare Outcomes) is a telementoring program that trains primary care providers to treat complex conditions they’d normally refer to a specialist. Rather than connecting patients directly to specialists through telemedicine, ECHO connects doctors, nurses, and other frontline providers to specialist knowledge so they can deliver that care themselves, right in their own communities. The program launched in 2003 at the University of New Mexico and now operates across more than 200 countries, with 2,813 active programs as of 2024.
How ECHO Started
Sanjeev Arora, a gastroenterologist at the University of New Mexico, created Project ECHO to solve a problem he saw firsthand: patients with hepatitis C in rural New Mexico couldn’t access the specialized treatment they needed. In remote towns and sparsely populated counties, disease management specialists were scarce and the latest treatments were out of reach for most low-income patients. Most rural doctors didn’t want to treat hepatitis C because they simply didn’t have the expertise.
Arora’s insight was that instead of trying to bring every patient to a specialist, he could bring specialist knowledge to the providers already embedded in those communities. He built a training model where rural clinicians could learn from hepatitis C experts through regular video sessions, gradually developing enough skill and confidence to manage the disease on their own. That original hepatitis C program became the template for what ECHO is today.
How the Model Works
ECHO uses what’s called a “hub and spoke” structure. The hub is a team of specialists at an academic medical center or other expert institution. The spokes are the frontline providers out in the field: family doctors, nurse practitioners, community health workers, and others who participate from their own clinics.
During a typical ECHO session, participants join a video call where they present real, anonymized patient cases to the specialist team and to each other. The group discusses the case, offers recommendations, and works through clinical challenges together. This isn’t a one-way lecture. ECHO describes its philosophy as “all teach, all learn,” meaning the rural provider who sees dozens of patients with a given condition often has practical insights the specialist doesn’t.
Sessions run on a recurring schedule, often weekly, creating an ongoing learning community rather than a one-off training. Providers who attend earn continuing medical education (CME) credits, with one session equaling one credit. These credits are available to physicians, nurses, nurse practitioners, physician assistants, physical therapists, psychologists, and occupational therapists, among others. Most programs encourage participants to attend at least 70% of sessions in a given series.
How ECHO Differs From Telemedicine
The distinction matters. Telemedicine connects a patient directly to a remote clinician through a screen. ECHO connects a clinician to other clinicians for training and mentorship. The patient never appears in an ECHO session. Instead, their provider learns how to manage their condition and then delivers that care locally. Over time, this builds permanent capacity in underserved areas rather than creating dependence on a distant specialist for each individual visit. It also removes the need for patients to travel long distances, which is especially significant in rural and low-income communities where transportation is a barrier to care.
Conditions It Covers
What started with hepatitis C has expanded dramatically. The ECHO model now addresses more than 100 complex conditions, including diabetes, chronic pain, addiction, HIV, cancer prevention, rheumatologic diseases, mental and behavioral health, hospice care, and complex multisystem disease. Major cancer centers like MD Anderson have adopted ECHO for oncology training, and programs exist for nearly every chronic disease category where specialist access is limited.
Evidence of Impact
ECHO’s strongest evidence comes from measurable changes in how providers practice and how patients fare afterward.
Diabetes
Nearly 900 patients of ECHO-trained providers reduced their A1c levels (a key marker of long-term blood sugar control) by an average of 1.2%. That number matters more than it might sound: every 1% reduction in A1c lowers the risk of complications affecting the kidneys, eyes, and nerves by 37%.
Opioid Prescribing
The opioid crisis is where ECHO’s impact has been most striking. Before the program launched its addiction psychiatry track, New Mexico had only 14 physicians per million residents certified to prescribe buprenorphine, a key medication for opioid use disorder. After the program, the state experienced a 100-fold increase in certified prescribers and rose to fourth in the nation. Providers who went through ECHO training reduced opioid prescriptions to their patients by 87%, compared to a 49% national reduction over the same period. Compared directly to non-ECHO providers, ECHO participants prescribed 33% lower average opioid doses and their patients were 14% less likely to receive unsafe doses.
A hospital-based ECHO program focused on screening for opioid use disorder saw screenings jump from 438 to over 3,400 between its first and second year. The number of patients started on treatment for opioid addiction increased more than fivefold. Among those screened, 42% began treatment and 26% were discharged with a coordinated care plan.
Nursing Home Care
A study of 11 nursing homes in Maine and Massachusetts found that ECHO-trained facilities were 75% less likely to physically restrain elderly patients experiencing psychotic episodes and 17% less likely to prescribe antipsychotic medications, both considered improvements in care quality.
Cancer Screening
In cancer-focused ECHO programs, 60% of participants reported improved ability to conduct appropriate screenings and referrals, and 88% reported better overall patient care. In one follow-up program, trained nurses performed over 3,100 cervical cancer screenings and identified 61 presumptive positive cases, offering free treatment for each.
HIV and Professional Isolation
HIV-focused ECHO programs increased clinical knowledge by 18 to 23% across participants. Perhaps just as important for retention in underserved areas, 66% of participants said they felt less professionally isolated and 30% reported greater professional satisfaction.
How ECHO Programs Are Funded
Sustainability is one of the practical questions anyone looking to start or join an ECHO program will encounter. There’s no single funding model. Instead, states and health systems have developed several approaches, many rooted in Medicaid financing.
In New Mexico, the state requires all four of its Medicaid managed care organizations to contract with the ECHO Institute and includes the funding in their per-member-per-month capitation rates. Oregon has taken a voluntary approach, with health plans contracting with coordinated care organizations to support a statewide ECHO network. California’s Medicaid plans have partnered with the UC Davis ECHO hub specifically for chronic pain management. Colorado ran a state-funded chronic pain pilot from 2015 to 2017 using the ECHO model as a disease management program.
Beyond Medicaid, accountable care organizations can fund ECHO internally through shared savings. Some states allow primary care providers who develop expertise through ECHO to count as specialty care within a health plan’s network, helping plans meet network adequacy requirements. Others offer higher care coordination payments to providers who participate, or frame ECHO as a cost-effective alternative to referring patients out for specialty services.
Global Scale
As of 2024, Project ECHO operates 2,813 programs with participants in 202 countries and territories. India alone hosts more than 400 ECHO hubs and partnerships in every state. The model has proven adaptable partly because it’s technology-light: all you need is a reliable video connection, a willing specialist team, and frontline providers who show up consistently. The infrastructure requirements are minimal compared to building new clinics or recruiting specialists to underserved areas, which is why the model has scaled so rapidly in low- and middle-income countries where specialist shortages are even more severe than in rural America.
