What we aim to solve

SOURCE: Self-reported by organization

Lyme disease is the most common vector-borne disease in the United States with an incidence of over 476,000 cases a year [1]. When treated early and adequately, most patients are restored to health. Even so, treatment failure rates remain unacceptably high, ranging between 10-35% [2]. In addition, many patients are not diagnosed early and experience higher treatment failure rates. Unfortunately, we know very little about how to treat late Lyme disease—no studies have been done, and short term protocols often prove inadequate. When treatments fail, patients may develop persisting debilitating symptoms, a condition commonly referred to as persistent or chronic Lyme disease. The state of the science today does not permit us to adequately characterize persistent Lyme disease, identify the factors that increase the risk of developing it, or determine the optimal treatment approach for different patients using individualized care. Patients with chronic Lyme disease are denied access to th

What are the organization's current programs, how do they measure success, and who do the programs serve?


The problem is chronic Lyme disease

Many patients with Lyme disease remain ill after a short term course of antibiotics and have a quality of life that is equal to that of patients with congestive heart failure. Debate exists about whether these persistent symptoms are caused by on-going infection or an inflammatory response. Treatment is controversial because:
* There is no current Lyme disease test that can determine whether a patient has active infection,
* Insurers are reluctant to cover unproven treatments,
* A major medical society denies the existence of persistent Lyme disease and the need to provide treatment, and
* Physicians who treat Lyme disease are targeted by medical boards.

Why this is important?

Patients with chronic Lyme disease are denied access to the diagnosis, treatment, and insurance coverage they need to become well. Patients are denied treatment options on the basis that evidence of treatment effectiveness has not been demonstrated. However, no research into treatment options for chronic Lyme patients is being conducted. Unless clinically relevant data is developed, patients with chronic Lyme disease will continue to abandoned by the medical system and will not get the care they need to get well.

How we can address this problem?

To solve these issues, we need clinically relevant data. However, Lyme disease is a research disadvantaged disease. Neither the government nor pharmaceutical companies have demonstrated an interest in researching treatments that might restore or improve the quality of life for patients with chronic Lyme disease. The last NIH funded treatment trials was funded over 20 years ago. The three funded before that yielded conflicting results, were too small (just 37 to 129 enrolled) to permit subgroup analysis, and excluded too many patients (over 85% of those who applied) to apply to most patients seen in clinical practice.
In 2015, launched MyLymeData to accelerate the pace of research for Lyme disease by generating data and knowledge that leads to actionable insights. The goal is to develop the evidence base required to change health care policy in Lyme disease, increase access to care, and improve the standard of care for treatment.

Charting impact

Four powerful questions that require reflection about what really matters - results.

Founded in 1989, the mission of is to harness the power of tens of thousands of patients to improve patient care and to accelerate the pace of Lyme disease research. We do this through large-scale science-based advocacy, communications, and patient-driven big data research. is powered by patients. We believe there is strength in numbers. We represent hundreds of thousands of patients and provide them with the tools essential to empowerment. Educated and informed patients are the key to improving health care outcomes. We provide patients with the information that empowers them to make sure that they receive the care they need.
True power comes from having informed patients involved in all levels of decision making—from education, to legislation, and even science. Together we amplify the patient voice to drive health care policy change.
Through the MyLymeData patient registry, we develop the data necessary to better characterize persistent Lyme disease and to evaluate patient outcomes based on the real world care they receive from their clinicians. To receive the care they need to get well, patients must:
• Receive care that is patient-centered and improves their health,
• Know that there are divergent diagnostic and treatment approaches used by different clinicians,
• Have access to providers that can provide quality medical care,
• Be given the information necessary to make informed choices about diagnosis and treatment (including the risks and benefits of different treatment options), and
• Be afforded the opportunity to make informed treatment choices in consultation with their clinicians based on their individual circumstances and treatment preferences (e.g. shared medical decision-making).
To achieve healthcare policy change through advocacy, patients should be involved at all levels of healthcare policy decision making. This includes having a seat at every forum that discusses Lyme disease (nothing about us without us). Beyond this, patient representation must be authentic, meaningful, and accountable to the community. To influence health care policy reform, patients need the healthcare data essential to better characterize Lyme disease (particularly persistent Lyme disease) and the effectiveness of treatment options and their associated side effects.
Accelerating research that is patient-driven requires that:
• Research be based on clinically relevant research populations and use interventions and research outcomes that patients regard as important,
• Patient-generated data be pooled in a patient registry to better characterize the disease, analyze the risks and benefits of available treatment options, and identify how different subgroups of patients respond to treatment,
• Patients assist researcher recruitment efforts for clinical trials,
• Patient organizations collaborate with other organizations to build out a robust research engine that may include biorepositories, clinicians, industry, and researchers

Our strategies for making this happen include:
• developing and sustaining an extensive and robust communications network for patients and clinicians,
• providing comprehensive and trustworthy information to patients that they need to become diagnosed and treated,
• mobilizing tens of thousands of patients in advocacy and patient-driven research,
• advocating for healthcare policy change that will eliminate access to care barriers that patients face, increase research funding, and promote the use of shared medical decision making, and
• accelerating the pace of research through our patient registry and research platform, MyLymeData.

Communications: is the largest and most trusted Lyme disease patient communications network in the nation, drawing millions of visitors to its website annually. Our reach to patients is unparalleled, with widely distributed website content, blogs, social and print media, including our digital publication, The Lyme Times.
New patients rely on us to provide information to get promptly diagnosed, tested, and treated. Patients with chronic Lyme disease rely on us for timely, accurate news and commentary through our website, blogs, newsletters, and our online support and discussion forum: U.S. National Lyme Group. provides patients with the tools to get promptly diagnosed and treated. Our Symptom Checklist helps patients determine whether they have been exposed to Lyme disease and assess whether they should see a healthcare practitioner. Millions of people have used the symptom checklist to help obtain an earlier diagnosis. Our physician referral program gives patients information about local physicians who treat Lyme disease.
Advocacy: Our advocacy efforts benefit from the thousands of patients who lend their voices to promote change. Over 14,000 patients answered our call to contact legislators to pass the 21st Century Cures Act that created the Tick-Borne Disease Working Group, where patients for the first time have a seat at the table and discussions that would have occurred behind closed doors are now public.
Representatives from have served on Working Group subcommittees since its inception, drafting portions of the report that goes to Congress, testifying at their hearings, nominating patient representatives who are qualified to serve on the Work Group, and informing the patient community regarding the deliberations and resulting outcomes from this group.
Research: Patients are the most underutilized resource in medical research. MyLymeData is a patient-led research registry that uses innovative technology that by-passes traditional research bottlenecks. It allows patients to pool their data to accelerate research using real world evidence.
The registry uses one of the highest quality and most secure registry platforms – the same one that serves National Institutes of Health patient registries.
MyLymeData seeks to:
• generate actionable data and a knowledge base to improve care and promote policy reform,
• build the Lyme community research capacity,
• foster research partnerships and collaborations with researchers, clinicians, and blood/tissue biobanks,
• identify treatment response subgroups and determine the factors that make patients well, and
• facilitate traditional research by helping researchers develop hypotheses, determine outcomes that matter to patients, and recruit patients for clinical trials.
We have enrolled over 14,000 participants, collected over 5 million data points, published five peer-reviewed studies, and seven white papers and scientific posters. MyLymeData has been hig
