Defining Frailty in Research Abstracts: A Systematic Review and Recommendations for Standardization.

ABSTRACT: Multiple definitions of frailty are used. We sought to quantify the frequency that frailty is insufficiently defined in published abstracts. We conducted a systematic review of MEDLINE/PubMed for English abstracts of original research investigating frailty as an exposure or outcome in humans from 2015-2017. A complete definition of frailty included: 1) a named measure of frailty, including "frailty" alone, 2) details on variables included (e.g. grip strength), 3) number of variables included (e.g. 33-item frailty index), and 4) details on cutoffs or levels of frailty unless a definition was used continuously. Our search yielded 1,110 titles; 490 abstracts met review criteria, 348 abstracts had any definition of frailty and were included. Majority reported a single measure of frailty (n=313
