Responding to
COVID-19 Together

We are honored to have worked over the past decade with our country’s first responders, doctors, nurses, and healthcare administration and we have been amazed with their response and selflessness.

The situation is evolving quickly, and Arcadia is rapidly developing and deploying novel tools to support our delivery systems throughout the crisis. This site will be updated with our latest progress and success stories from the field.

Arcadia’s Long-COVID Research Initiative

As many as 1 in 10 people may have symptoms of COVID-19 for months after their initial infection. To address this public health crisis, Arcadia is contributing our research data asset (comprising aggregated, de-identified records for more than 155 million patients) and our data science expertise to the COVID Patient Recovery Alliance (PRA). The PRA is a multi-sector collaboration supporting the energy and innovation of government and private-sector leaders as they care for patients with long-term health consequences from COVID-19 infection.

Arcadia’s Evolving Population Health Response Kit

As we work together to flatten the curve in the spread of COVID-19, health systems are now using the new COVID-19-specific algorithms and workflows within Arcadia’s population-level platform. Arcadia is supporting the healthcare system in several ways, among them:

Patient Stratification

Population Stratification Algorithms

At the center of our population health strategy to support COVID-19 is a novel set of stratification models to identify patients of highest need and risk. These inform engagement efforts and the allocation of limited primary care and navigation services. Arcadia is rolling these out for all patients with any activity in the last 5 years. 

High-to-moderate risk of complications from COVID-19

  • High risk for COVID-19 complications with behavioral health complications
  • High risk for COVID-19 complications without behavioral health complications
  • Moderate risk for COVID-19 complications with behavioral health complications
  • Moderate risk for COVID-19 complications without behavioral health complications

Patients with chronic or current care needs

  • Physical Health Vulnerabilities
  • Mental Health Vulnerabilities

Patients that are symptomatic, or diagnosed with COVID-19

  • Symptomatic or Diagnosed and sent home
  • Discharged/Recovered

Patients that are healthy or otherwise historically unengaged

Cohorts were designed from factors that are believed to elevate a patient’s risk of having serious complications should they become infected with COVID-19. An additional behavioral health stratification was layered in as it can further complicate feelings to isolation and anxiety. Younger populations are generally at lower risk of serious illness or death from COVID-19, while over 50% of members age 80 or older have evidence of a condition that will increase their likelihood of serious complications as it relates to COVID-19. 

Outreach, Education, Symptom Checking and Triage

Arcadia has configured its Outreach and Engage products with content specific to education and triage of COVID-19. The interactive content, currently available in 9 languages, is delivered to patients directly on their mobile device without any pre-configured software. Acting as an extension of the care team, the content guides patients through access information for telehealth and hotlines, provides a personalized interactive COVID symptom checker, and allows health systems to securely capture information about patients’ symptoms and care needs.


As organizations quickly evolve to meet the demands and constraints of COVID-19, patients need consistent, trusted information about access to care and new or relevant services to help them cope with the crisis. 

  • Branded and tailored message gives patients a trusted local face.
  • Tailored list of resources available to the patient, including hotlines, mental health programs and e-visit capabilities.
  • Information about practice closures and alternative access points.
  • Direct link integration to patient portals for scheduling and telehealth.
  • Link to dynamic symptom check screener or other web tools from the provider. 

Symptom Check Screening tool

Give patients the most accurate, up-to-date information on COVID-19 symptoms and pair it with “escalation points” to urgent care, emergency room, telehealth visits and hotline numbers. 

  • Patients receive a dynamic mobile screening tool aligned with evolving CDC guidance. 
  • Patients attest to symptoms and describe recent travel or testing. 
  • Patients without known symptoms are re-assured and reminded to stay home and practice social distancing.
  • Patients with known symptoms are directed to the provider’s phone numbers or web portals to access care.

Patient Reported Outcomes

For symptomatic patients or those at higher risk, provide a regular electronic check-in on evolving symptoms, care needs and social factors.

  • Ongoing symptom surveillance lets the patient attest to the quality and severity of their symptoms and builds a longitudinal dataset.
  • Self-triage with dynamic reactions. If patient attests to major symptoms or care needs, dynamically respond and direct them to specific medical or social services.
  • We all have higher level of anxiety. Reassure the patient (when appropriate) that certain symptoms are not associated by the CDC to COVID-19.
  • Regular re-enforcement of clinical and mental health services and public health guidance.

Care Team Extension

Now, more than ever, care teams around the country need the support and extenders that population health programs can provide. Access to primary care is severely reduced due to office closures and patients’ fear of getting sick. The most vulnerable of our population risk falling through the cracks during this crisis.

Care management programs

Combining our enhanced stratification algorithms and our broad automated engagement platform, care teams can isolate and focus on complex co-morbid patients at the highest risk of falling through the cracks.

Our care management software has been enhanced to include support for COVID, as well as dozens of high risk medical and social factors.

An automation engine can “escalate” patients to a navigator phone call within minutes of a patient responding to a mobile screener.

Research and Analytics

You need access to good, fast, trusted data to effectively deploy resources to respond to the pandemic. Arcadia is surveilling systems and diagnostics from all your EHRs, HIEs, labs, claims systems and directly from patients.


Nightly extractions of patient charts including structured, pseudo-structured, and unstructured note data.


Real time alerts of admissions, discharges, and transfers from hospitals and HIEs.


Testing response made available to understand what is happening to patients with an integrated dataset. 

Patient Responses

Real time additions of data entered by patients via text message surveys or entered by care managers on the phone with a patient.  

Public/Private Partnerships

Arcadia has joined with other private sector organizations to form the COVID-19 Healthcare Coalition, a collaborative private-industry response to the novel coronavirus. Its mission is to save lives by providing real-time learning to preserve healthcare delivery capacity and protect U.S. populations. Each coalition partner is bringing its unique assets, sharing resources and plans, and working together to support those on the front lines in responding to COVID-19. Learn More

Arcadia is also part of the COVID-19 Research Database.
