Geriatric assessment for older adults admitted to the emergency department: A systematic review and meta-analysis

Older adults are the most frequent users of emergency services. Comprehensive geriatric assessment (CGA) can help identify high-risk older adults at an early stage. We conducted a systematic review and meta-analysis to identify and evaluate CGA tools used in the emergency department (ED), analyze their predictive validity for adverse outcomes and recommend tools for this particular situation. We systematically searched Medline, Web of Science and CENTRAL for eligible articles published in peer-reviewed journals that observed patients ≥65 years admitted to the ED, used at least one assessment tool and reported adverse outcomes of interest. We performed a descriptive analysis and a bivariate meta-analysis of the diagnostic accuracy and predictive validity of the assessment tools for the chosen adverse outcomes. 28 eligible studies were included. The pooled sensitivity (95% CI) of the assessment tools for predicting mortality within short (28–90 days) and long (180–365 days) periods after the first ED visit was 0.77 (0.61–0.89) and 0.79 (0.46–0.96), respectively, with specificity (95% CI) values of 0.45 (0.32–0.59) and 0.37 (0.14–0.65). These findings indicate that the tools used in the included studies had modest predictive accuracy for mortality and were more appropriate for identifying individuals at high risk of readmission in the short term than in the long term. Early use of assessment tools in the ED might improve clinical decision making and reduce negative outcomes for older adults. •The obsolescence of the population requires changes in medical care, especially in the emergency department (ED)•CGA may help to identify high-risk older adults (OA) at an early stage in order to treat them with geriatric therapy promptly•For the different domains of CGA there is a great variety of assessment tools•We evaluated the predictive validity for adverse outcomes and try to recommend assessment tools for OAs admitted to ED
