Role of Nursing Home Quality on COVID-19 Cases and Deaths: Evidence from Florida Nursing Homes.

The Coronavirus disease 2019 (COVID-19) disproportionately affects nursing home residents, resulting in an elevated risk for COVID-19 morbidity and mortality for this frail population. It is critical to understand whether nursing home quality is related to COVID-19 cases and deaths. Using publicly available data obtained from Centers for Medicare & Medicaid Services COVID-19 Nursing Home Dataset, Nursing Home Compare and Long-Term Care Focus, this study compares key nursing home characteristics, infection prevention and control deficiencies, and five-star ratings among Florida nursing homes with and without resident COVID-19 cases and deaths. The study further examines the association between facility and resident characteristics, quality indicators, and COVID-19 cases and deaths. Findings from our study indicate that through late October 2020, over 90% of Florida nursing homes have at least one resident case and 65% have at least one resident death. The likelihood of having COVID-19 cases is more related to ownership status, facility size and average occupancy rate, rather than quality indicators. Associations between infection prevention and control deficiencies, overall quality ratings, and presence of COVID-19 resident deaths varied across different phases of the pandemic (e.g., overall five-star rating was found related to the odds of having resident deaths after, but not during, the surging stage). Training, uptake, and adherence to infection control procedures are needed to better protect the vulnerable nursing home resident population.

Time Distributions of Common Respiratory Pathogens Under the Spread of SARS-CoV-2 Among Children in Xiamen, China.

Objectives: The aim of this study was to observe the effect of COVID-19 prevention and control measures on the transmission of common respiratory viruses in a pediatric population. Methods: This was a retrospective observational study. The study population was selected from children with respiratory diseases who attended Xiamen Children's Hospital from January 1, 2018 to January 31, 2021. All children were screened for influenza virus, parainfluenza virus, respiratory syncytial virus (RSV), adenovirus, and Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The changes in respiratory virus detection rates before and after the SARS-CoV-2 intervention were analyzed using an interrupted time-series model. Polynomial curve fitting was also used to predict future short-term trends in respiratory virus detection. Results: A total of 56,859 children were seen at Xiamen Children's Hospital from January 1, 2018 to Jan 31, 2021, of which 32,120 were tested for respiratory viruses via pharyngeal swabs. The overall positive detection rates of the four respiratory viral infections decreased significantly (P = 0.0017) after the implementation of the quarantine and school suspension measures in January 2020. Among them, the detection rate of RSV decreased most significantly (P = 0.008), and although there was no statistically significant difference in the detection rates of the influenza virus, parainfluenza virus, and adenovirus, a downward trend in the graph was observed. The positive detection rates of RSV in the 0-1-, 1-3-, and 3-7-year-old groups all decreased significantly (P = 0.035, 0.016, and 0.038, respectively). The change in the positive detection rate of RSV was relatively stable in the 7-18-year-old group. A total of 10,496 samples were tested for SARS-CoV-2, and no positive cases were reported. Conclusions: The combination of preventive and control measures for COVID-19 reduced the detection rate of four common respiratory viruses, with the greatest impact on RSV. If prevention and control measures continue to be maintained, the overall detection rate or absolute number of detections for the four respiratory viruses will remain low in the short term. However, this trend is likely to vary with the changes in measures.
