Objectives: The Abbot ID NOW COVID-19 assay and Quidel Sofia 2 SARS Antigen FIA are point-of-care assays that offer rapid testing for severe acute respiratory syndrome coronavirus 2 viral RNA and nucleocapsid protein, respectively. Given the utility of these devices in the field, we investigated the feasibility and safety of using the ID NOW and Sofia assays in the public health response to the coronavirus disease 2019 pandemic and in future public health emergencies.
Methods: A combination of utilization and contamination testing in addition to a review of instrument workflows was conducted.
Results: Utilization testing demonstrated that both tests are intuitive, associated with high user test success (85%) in our study, and could be implemented by staff after minimal training. Contamination tests revealed potential biosafety concerns due to the open design of the ID NOW instrument and the transfer mechanisms with the Sofia. When comparing the workflow of the ID NOW and the Sofia, we found that the ID NOW was more user-friendly and that the transfer technology reduces the chance of contamination.
Conclusions: The ID NOW, Sofia, and other emerging point-of-care tests should be used only after careful consideration of testing workflow, biosafety risk mitigations, and appropriate staff training.

Background: There are gaps in our understanding of the clinical characteristics and disease burden of the respiratory syncytial virus (RSV) among community-dwelling adults. This is in part due to a lack of routine testing at the point of care. More data would enhance our assessment of the need for an RSV vaccination program for adults in the United Kingdom.

Importance: The Walter Index is a widely used prognostic tool for assessing 12-month mortality risk among hospitalized older adults. Developed in the US in 2001, its accuracy in contemporary non-US contexts is unclear.
Objective: To evaluate the external validity of the Walter Index in predicting posthospitalization mortality risk in Brazilian older adult inpatients.
Background: Women veterans represent a growing number of veterans with limb loss who receive Veterans Health Administration treatment. This study surveyed a large sample of veterans about their satisfaction with prosthetic-related care and sought to understand how women veterans with limb loss rate their satisfaction with prostheses and care.
Methods: We conducted a cross-sectional, mixed-mode survey of 46,614 veterans with major upper or lower limb amputation or partial foot amputation to assess amputation type, prosthesis use intensity, satisfaction with prostheses and services, and quality of life.

Background And Objectives: Healthcare-associated infections (HAI) are a leading contributor to morbidity and mortality in hospitalised neonates. Diagnosing neonatal HAI is challenging owing to non-specific symptoms and lack of definitive diagnostic markers, contributing to high rates of inappropriate antibiotic use. This study evaluated the theoretical impact of implementing a bedside tool for decision-making on antibiotic length of therapy (LOT).

The early diagnosis of a disease relies on the reliable identification and quantitation of multiple core biomarkers in real-time point-of-care (POC) testing. To date, most of the multiplex photoelectrochemical (PEC) assays are inaccessible to home healthcare due to cumbersome steps, long testing time, and limited detection efficiency. The rapid and fast-response generation of independent photocurrent for multiple targets is still a great challenge.
