Almost 90% of COVID-19 admissions involve comorbidities



The hospitalization rate for COVID-19 is 4.6 per 100,000 population, and almost 90% of hospitalized patients have some type of underlying condition, according to the Centers for Disease Control and Prevention.

Underlying conditions among adults hospitalized with COVID-19

Data collected by the newly created COVID-19–Associated Hospitalization Surveillance Network (COVID-NET) put the exact prevalence of underlying conditions at 89.3% for patients hospitalized during March 1-30, 2020, Shikha Garg, MD, of the CDC’s COVID-NET team and associates wrote in the MMWR.

The hospitalization rate, based on COVID-NET data for March 1-28, increased with patient age. Those aged 65 years and older were admitted at a rate of 13.8 per 100,000, with 50- to 64-year-olds next at 7.4 per 100,000 and 18- to 49-year-olds at 2.5, they wrote.

The patients aged 65 years and older also were the most likely to have one or more underlying conditions, at 94.4%, compared with 86.4% of those aged 50-64 years and 85.4% of individuals who were aged 18-44 years, the investigators reported.

Hypertension was the most common comorbidity among the oldest patients, with a prevalence of 72.6%, followed by cardiovascular disease at 50.8% and obesity at 41%. In the two younger groups, obesity was the condition most often seen in COVID-19 patients, with prevalences of 49% in 50- to 64-year-olds and 59% in those aged 18-49, Dr. Garg and associates wrote.

“These findings underscore the importance of preventive measures (e.g., social distancing, respiratory hygiene, and wearing face coverings in public settings where social distancing measures are difficult to maintain) to protect older adults and persons with underlying medical conditions,” the investigators wrote.

COVID-NET surveillance includes laboratory-confirmed hospitalizations in 99 counties in 14 states: California, Colorado, Connecticut, Georgia, Iowa, Maryland, Michigan, Minnesota, New Mexico, New York, Ohio, Oregon, Tennessee, and Utah. Those counties represent about 10% of the U.S. population.
