Patient Navigation Program

Undiagnosed and ultra-rare patients and families are paired with a navigator who can support them with managing medical care, accessing social services, applying to diagnostic programs, connecting to research opportunities, matching with therapeutic options, and building community. Navigators also facilitate consolidation of clinical, fundraising, community building, and symptom assessment strategies across undiagnosed and rare disease patient communities. Patients can receive this service at any point in their journey from symptom onset to diagnosis and beyond.

Charting impact

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

The UDNF aims to foster collaboration among patients, clinicians, and scientists to enhance the quality of life of undiagnosed and ultra-rare disease patients. We do this by mitigating barriers to equity and access in healthcare; setting standards for patient management; and bridging diagnosis and therapeutics as well as research and clinical care in undiagnosed patients and patients with ultra-rare diseases.

Led by and for patients and their families, the UDNF will become the central resource for the undiagnosed community. From when a patient first experiences unexplained symptoms to their 10-year anniversary of effective treatment, the UDNF will provide the resources, community, and research they need to live their best lives. No patient or family will have to traverse the unknown alone.

We envision a learning healthcare system where researchers, clinicians, and patients work together to advance individual and community well being. By leveraging advancements in science, technology, and service delivery, we aim to continuously improve health quality and efficiency for undiagnosed patients.

Growth & Sustainability:
1. Grow into a sustainable, high-impact nonprofit organization that collaborates with a network of clinical sites and research cores.

Community Outreach strategies:
1. Build a community by and for all patients with undiagnosed and ultra-rare diseases and their families.
2. Serve as the leading resource for trustworthy information about undiagnosed and ultra-rare diseases and services.
3. Ensure underrepresented patients have equitable access to diagnosis, therapeutics, research, and support.

Patient & Family Navigation strategies:
1. Improve medical management, care coordination, access to social services, community support, and mental health services for undiagnosed and ultra-rare patients and their families.
2. Improve the patient and family experience of the diagnostic process and transition to therapeutics, regardless of when or whether a diagnosis is achieved.
3. Use consolidated tools and strategies across undiagnosed and ultra-rare disease communities.

Patient-Centered Research & Clinical Care strategies:
1. Make the diagnosis of ultra-rare diseases more accessible, equitable, accurate, and efficient.
2. Advance diagnosis and knowledge of ultra-rare diseases.

Balance sheet

Fiscal Year: Nov 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
