The pandemic of COVID-19 is growing, and a shortage of masks and respirators has been reported globally. Policies of health organizations for healthcare workers are inconsistent, with a change in policy in the US for universal face mask use. The aim of this study was to review the evidence around the efficacy of masks and respirators for healthcare workers, sick patients and the general public. ⋯ The study suggests that community mask use by well people could be beneficial, particularly for COVID-19, where transmission may be pre-symptomatic. The studies of masks as source control also suggest a benefit, and may be important during the COVID-19 pandemic in universal community face mask use as well as in health care settings. Trials in healthcare workers support the use of respirators continuously during a shift. This may prevent health worker infections and deaths from COVID-19, as aerosolisation in the hospital setting has been documented.

The concept of prefrailty lacks clarity. Often, prefrailty is defined in relation to frailty and less often as a distinct concept. Theoretical evidence for prefrailty is minimal unlike frailty, which has been examined for decades although consensus about how to measure frailty has not been achieved. ⋯ As a result of conducting this concept analysis, we found that prefrailty was defined as a clinically silent process that predisposes individuals to frailty. Prefrailty, as a concept, was derived from the Fried's operational definition for frailty. Attributes, antecedents, consequences, and related terms will help clinicians consider how prefrailty presents in older adults separate from frailty. Further research is needed to build upon our understanding from this concept analysis. Tweetable Abstract: Prefrailty is unclear as a concept - Research on sociodemographic characteristics of older adults living with frailty will help clarify.
