PMID 35085507WHAT IT FOUND
Community spread of influenza A(H3N2), influenza B, and RSV is linked to higher rates of heart and lung rehospitalizations for nursing home residents.
Clinicians should intensify infection control and monitoring during these specific viral seasons.
Key findings
01Cardiorespiratory readmission rates increased by approximately 1% for every 5% increase in circulating influenza A(H3N2), influenza B, and RSV.
02When respiratory viruses were in season, cardiorespiratory rehospitalization rates increased by approximately 6% for influenza A(H3N2), 3% for influenza B, and 5% for RSV.
03RSV was associated with increased rehospitalization rates for heart failure and COPD, while influenza A(H3N2) was associated with increased rates for asthma and COPD.

What it does not show
Viral activity data were only available at the regional level, so the study could not determine which individual residents were infected or account for facility-specific outbreaks. The analysis did not adjust for influenza vaccination status, individual comorbidities, or other co-circulating pathogens. The study period (2012-2015) may not reflect current viral patterns or post-pandemic infection control practices.
Declared interests
The study was supported by non-U.S. government and NIH extramural research grants. No specific commercial conflicts of interest were declared in the provided text.
The easy way to misread this
Do not assume this study proves that infection control interventions will reduce rehospitalizations. It is an observational study linking community viral levels to admission rates; it does not test the effectiveness of specific nursing interventions.
