Arcadia analysis of COVID-19 hospitalized patient data shows higher post-discharge mortality rate compared to non-COVID patients

  • 15.1% of COVID-19 patients die within the 90-day window after discharge, including 20.6% of patients classified as very high risk.
  • More patients died of COVID-19 within 30 days of discharge than medical admissions or patients with sepsis in all risk bands.
  • Patients discharged for COVID-19 are 2.4 times more likely to die within the 30-day post-discharge window than those discharged from medical admission. They are 1.6 times more likely to die than a patient discharged for sepsis.

Arcadia compared post-hospital outcomes for COVID-19 with post-hospital outcomes for sepsis, as both categories represent life-threatening infections. The diagnostic category of sepsis generally reflects serious bacterial infections, but viral infections, including COVID-19, can also present life-threatening challenges.

“These data remind us of just how devastating COVID-19 can be in the body, both immediately and over the long term,” said Rich ParkerMD, Chief Medical Officer at Arcadia. “It’s important for people to understand that even if you get out of the hospital, the journey is still long. How many COVID patients will get back to functional status, walk, talk, work, eat, compared to bed with a We have to making sure our high-risk patients understand how important it is to get vaccinated and to receive a booster – the best way to avoid hospitalization.

of Arcadia mission is to provide the web of data and insights our customers need to uncover and meet the needs of patient populations to improve care and outcomes,” said Jacob Hochbergexecutive director of customer knowledge at Arcadia. “The HIPAA-compliant, HITRUST-CSF and NCQA-certified Arcadia Analytics platform continuously aggregates and maintains up-to-date population health data assets so our customers have actionable insights. We have a Huge empathy for all the organizations we work with who are in the trenches fighting COVID, and we’re constantly working to support them with data and workflow capabilities.”

Long-COVID: when symptoms last for weeks or months
Many hospitalized patients will have a long road to recovery after discharge, but many more COVID-19 patients will be dealing with long COVID, where COVID symptoms can linger for weeks or months with painful consequences for patients and their families.

Arcadia recently published a white paper titled “What’s Driving Long COVID? Understanding Complex Interactions with Real-World Data.” Common symptoms of long COVID include fatigue, cough, shortness of breath, muscle and joint pain, chest pain, loss of taste and smell, difficulty thinking or concentrating (“brain fog”) , depression, anxiety and abnormal sleep patterns. These symptoms can occur even in people who had mild symptoms of COVID-19.

As many as one in 10 people may show symptoms of COVID-19 for weeks or months after their initial infections, resulting in a staggering total number of long-lasting COVID-19 cases that continues to rise. A new to study speak University of Michigan estimates that 43% of people worldwide – or more than 100 million people – who have been infected with COVID-19 “have experienced persistent health problems or are still reporting problems”.

About Analysis
Data for this analysis was collected from 3,836 patient records in calendar year 2020 from Arcadia Data Research (, Burlington, MA), a standardized and anonymized clinical and operational dataset containing more than 150 million patient records comprised of data from electronic health record (EHR) systems, practice management systems, claims data, and patient records. health care payer eligibility, care management and clinical assessment data, and other third-party sources.

To account for variation in population acuity, an analysis was performed on four distinct risk bands based on the CMS Hierarchical Condition Category (HCC) risk model:

Risk group 1 (6% of admissions): HCC risk score Risk group 2 (20% of admissions): HCC risk score between 1 and 2
Risk group 3 (22% of admissions): HCC risk score between 2 and 3
Risk group 4 (52% of admissions): HCC risk score >= 4

Cause of death was not available for use in this analysis. Patients with COVID-19 can be discharged and die for unrelated reasons.
