Evaluation of federated learning variations for COVID-19 diagnosis using chest radiographs from 42 US and European hospitals.
The goals of this study were to compare a single-site, COVID-19 computer diagnosis system that used the Federated Averaging (FedAvg) algorithm with 3-client Federated learning (FL) models, and to evaluate the performance of the four FL variations. Researchers leveraged a FL healthcare collaborative that included data from five US and European healthcare systems encompassing 42 hospitals. They concluded that FedAvg could significantly improve generalization of the model in comparison with other personalization FL algorithms--FedProx, FedBN, and FedAMP--but at the cost of poor internal validity.

The association of strained ICU capacity with hospital patient racial and ethnic composition and federal relief during the COVID-19 pandemic.
Investigators sought to identify the association between strained intensive care unit (ICU) capacity during the COVID-19 pandemic and hospital racial and ethnic patient composition, federal pandemic relief, and other hospital characteristics. They found that hospitals with large Black patient shares experienced greater strain during the pandemic. These hospitals received more federal relief; however, funding was not targeted overall toward hospitals with high ICU occupancy rates.

Responding to COVID-19 through interhospital resource coordination: a mixed-methods evaluation
Researchers sought to describe a novel hospital system approach to managing the COVID-19 pandemic, including multihospital coordination capability and transfer of COVID-19 patients to a single, dedicated hospital. They found that, with standardized communication, interhospital transfers were a safe and effective method of cohorting COVID-19 patients, were well-received by health care providers, and had the potential to improve care quality.

Hospital discharge during COVID-19: the role of social resources.
The purpose of this qualitative study was to examine the effect of the COVID-19 pandemic on the ability of patients to obtain and receive support post-discharge after medical or surgical hospital services. The researchers utilized the Individual and Family Self-Management Theory as a framework for semi-structured interviews conducted with 26 patients discharged from the hospital. The study found that the majority of participants described minimal impact on their ability to secure support, with the exception of one participant whose support changes radically affected her experience post-discharge. The researchers concluded that strong pre-existing social support networks were protective for patients returning home after hospitalization during the pandemic.

Comparison of outcomes and process of care for patients treated at hospitals dedicated for COVID-19 care vs other hospitals.
The purpose of this study was to analyze the mortality rate and complications associated with treatment at the COVID-19-dedicated hospitals. Findings showed that, in this cohort study, COVID-19-dedicated hospitals in Minnesota had multiple benefits, including providing high-volume repetitive treatment and isolating patients with the infection. This experience suggests improved in-hospital mortality for patients treated at dedicated hospitals.
