Elevance Health Public Policy Institute’s study on Long COVID published in JAMA Health Forum Study
Study Found Long COVID Associated With Increased Risk for Adverse Cardiovascular, Pulmonary Conditions and Mortality
For the study -- the largest national study of commercially insured individuals with long COVID that includes 12 months of follow up -- researchers examined utilization claims data for 13,435 US adults with long COVID and 26,870 US adults with no signs of COVID-19 for at least 18 months. After controlling for risk factors present pre-COVID-19, the researchers found that individuals diagnosed with long COVID, known in the medical literature as post-COVID-19 condition (PCC), were more likely to seek care for the following adverse outcomes:
- Cardiovascular events: The group with long COVID was 2.35 times more likely to experience cardiac arrhythmias, 2.17 times more likely to experience ischemic stroke, 1.97 times more likely to experience heart failure, and 1.78 times more likely to experience coronary artery disease than the group without long COVID.
- Pulmonary events: The group with long COVID was 3.64 times more likely to experience pulmonary embolism, 1.95 times more likely to experience moderate or severe asthma, and 1.94 times more likely to experience chronic obstructive pulmonary disease.
- Mortality: During follow-up period, the group with long COVID experienced increased mortality, with 2.8% of individuals with long COVID dying versus 1.2% of those without long COVID.
The researchers note that while risks were heightened for individuals who experienced a more severe episode of COVID-19 (i.e., requiring hospitalization), most individuals (72.5%) in the group with long COVID did not experience hospitalization during the acute phase of COVID. They add that many of the resulting conditions could have lasting effects on quality of life.
In addition, researchers emphasize that, compared with previous research efforts, this study revealed substantially higher mortality rates for individuals following COVID. They attribute this finding to the ability to evaluate data – including full mortality information – comprehensively across all care settings.
“We know from published literature that long COVID can result in fatigue, headache and attention disorder,” said
“While we have made impressive strides in our ability to prevent and treat COVID-19, this study points to the need for care management programs like those developed by
