Researchers investigated the frequency of hospital-onset COVID-19 cases and the hospital characteristics related to hospital-onset infections by SARS-CoV-2 in US.
By Pooja Toshniwal PahariaAug 30 2023Reviewed by Sophia Coveney In a recent study published in JAMA Network Open, researchers investigated the frequency of hospital-onset coronavirus disease 2019 cases and the hospital characteristics related to hospital-onset infections by severe acute respiratory syndrome coronavirus 2 in the United States .
About the study In the present study, researchers described monthly nosocomial COVID-19 incidence rates during the pandemic and evaluated associations between nosocomial COVID-19 incidence and different COVID-19 periods, SARS-CoV-2 testing practices, causative SARS-CoV-2 strain, and various hospital-level variables.
Related StoriesThe study exposure was individuals discharged within the included month of hospitalization. The team calculated hospital months based on the monthly admission COVID-19 testing rates. The rates of post-admission SARS-CoV-2 testing were determined based on the number of COVID-19 tests per 1,000 patient days.
Among the hospitals, most were situated in the southern parts of the US , predominantly non-teaching , and in the urban regions . COVID-19 waves before Delta strain emergence contributed to 49% of the hospital months. Post-admission rates of SARS-CoV-2 testing and COVID-19 incidence in the community rose with admission SARS-CoV-2 testing rates.

Researchers find key for transforming cancer cells to muscle in rhabdomyosarcomaFor six years, Professor Christopher Vakoc's lab at Cold Spring Harbor Laboratory has been on a mission to transform sarcoma cells into regularly functioning tissue cells. Sarcomas are cancers that form in connective tissues such as muscle. Treatment often involves chemotherapy, surgery, and radiation—procedures that are especially tough on kids. If doctors could transform cancer cells into healthy cells, it would offer patients a whole new treatment option—one that could spare them and their families a great deal of pain and suffering.

Researchers study barriers and facilitators to accessing health care in rural MissouriRural Missourians often face more disparities in health outcomes than their urban and suburban counterparts, in part from challenges accessing health care—a problem amplified in recent years by a growing physician shortage. But a new study at the University of Missouri found that health and health care organizations are increasingly offering basic social services, such as transportation, housing, food, and mental health support, as they recognize these services contribute to a person's overall health.

Researchers develop a novel algorithm for mitigating COVID-19 spread in shipsThe COVID-19 pandemic has drastically affected human lives and the global economy. In particular, cruise ship companies around the world are among the worst hit industries, with ships becoming a hotbed of viral infection owing to their confined environment. With the economy slowly recovering in the post COVID-19 period, ship companies hope to return to normal operations by adopting a sustainable management model that prioritizes the health of ship passengers.
