Importance Head-to-head safety comparisons of the mRNA vaccines for SARS-CoV-2 are needed decision making; however, current evidence generalizes poorly to older adults, lacks sufficient adjustment, and inadequately captures events shortly after vaccination. Additionally, no studies date have explored potential variation in comparative vaccine across subgroups with frailty or an increased risk adverse events, information that would be useful tailoring clinical decisions. Objective To compare...

Older adults residing in long-term care facilities (LTCFs) are at a high risk of being infected with respiratory viruses, such as influenza and syncytial virus (RSV). Although these infections commonly have many cardiorespiratory sequelae, the national burden influenza- RSV-attributable events remains unknown for multimorbid vulnerable LTCF population. To estimate incidence hospitalizations that were attributable to RSV among residents quantify economic on US health system by estimating...

Abstract The coronavirus disease 2019 (COVID-19) pandemic has disproportionately impacted Black nursing home (NH) residents. Alzheimer’s Disease and Related Dementias (ADRD) may exacerbate disparities, however little empirical evidence exists on the degree to which race ADRD intersect impact COVID-19-related outcomes.

ABSTRACT Purpose Hip fractures in older adults cause severe pain that often necessitates opioid use. However, opioids may trigger falls result subsequent fractures. Studies examining the effects of on are limited by unmeasured confounding between opioid‐treated and untreated persons. To overcome this limitation, we used a self‐controlled case series (SCCS) design to investigate fracture risk during periods use after hip fracture. Methods The retrospective cohort included Medicare...
