Although widely feared by health care workers and the public, hospital-acquired COVID has never been a major factor in the pandemic, Dr. Schaffner said. “So why ask for something that’s actually not so critical? Let’s keep the emphasis on rapid, accurate reporting of people who are hospitalized because of this disease.”
Akin Demehin, senior director for quality and patient safety policy for the American Hospital Association, agreed that the rate of hospital-acquired COVID cases “has been very low throughout the pandemic.” That was one reason why CDC made this measure optional.
Dr. Eisenberg concurred with this view. “We worried about [hospital-acquired COVID] a lot, and then, because people were very careful, it wasn’t as much of a problem as we feared it would be.” But she added a note of caution: “Masking and other [preventive guidelines] are shifting in hospitals, so it will be interesting to see whether that affects things.”
CDC justifies its new policy
To put the hospital data reporting changes in context, it’s important to know that CDC will no longer directly track community levels of COVID and the percentage of tests that come back positive for COVID, which until now were used to measure transmission rates. (Laboratories no longer have to report these test data, whether they are in hospitals or in the community.) To track death rates, CDC will rely on the National Vital Statistics System, which is accurate but lags other kinds of surveillance by 2-3 weeks, according to the New York Times.
In a recent MMWR report, CDC defended its new COVID surveillance system, saying: “Weekly COVID-19 hospital admission levels and the percentage of all COVID-19–associated deaths will be primary surveillance indicators. Emergency department visits and percentage of positive SARS-CoV-2 laboratory test results will help detect early changes in trends. Genomic surveillance will continue to help identify and monitor SARS-CoV-2 variants.”
Clarifying the latter point, CDC said that national genomic surveillance, along with wastewater surveillance, will continue to be used to estimate COVID variant proportions. Dr. Eisenberg stressed the importance of genomic surveillance at the hundreds of sites that CDC now maintains across the country. But currently, many of these sites are only monitoring the level of COVID.
CDC also observed that COVID-19 hospital admission levels have been shown to be “concordant” with community levels of SARS-CoV-2 infection. Therefore, rates of COVID-associated admissions and the percentages of positive test results, COVID ED visits, and COVID deaths are “suitable and timely indicators of trends in COVID-19 activity and severity.”
Ready to shift to voluntary reporting?
In a news release, AHA praised the “streamlining” of CDC requirements for data reporting but said that it hoped that mandatory reporting would be phased out as soon as possible.
The association noted that this would require action by the Centers for Medicare & Medicaid Services. CMS now enforces the CDC requirements with a “condition of participation” (COP) provision, by which noncompliant hospitals could be excluded from Medicare. CMS has extended this COP to April 30, 2024, although it could choose to ask the Secretary of Health and Human Services to terminate it earlier.
If mandatory reporting were repealed, would most hospitals still report on the key COVID metrics? Mr. Demehin noted that before CMS implemented its COP, hospitals reported COVID data voluntarily, “and the participation rate was well over 90%. So setting up a mechanism similar to that is something we’ve encouraged CMS to consider.”
Dr. Eisenberg is skeptical. While bigger hospitals with more resources might continue reporting voluntarily, she said, safety-net hospitals in underserved areas might not, because they are especially short staffed. “Then you have disparities in which hospitals will report.”
