ObjectiveTo systematically review the associations of cognitive frailty with mortality and hospitalization in the elderly. MethodsThe VIP, PubMed, CNKI, WanFang Data, CBM, Embase, Cochrane Library and Web of Science databases were electronically searched to collect cohort studies on the association of cognitive frailty with mortality or hospitalization in the elderly from inception to May, 2023. Two reviewers independently screened the literature, extracted data and assessed risk of bias of the included studies. Meta-analysis was performed by R 4.2.2 software. ResultsA total of 19 cohort studies involving 63 624 elderly were included. The results of meta-analysis showed that compared with healthy elder, the elder with cognitive frailty had a higher mortality (OR=2.75, 95%CI 2.10 to 3.59, P<0.01) and hospitalization (OR=1.67, 95%CI 1.40 to 2.00, P<0.01). Subgroup analysis showed that cognitive frailty was related to the risk of death in different status of frailty and cognitive function, different assessment tools, different countries of development, different follow-up time and research sites. At the same time, different status of frailty and cognitive function and different levels of development of countries were related to the risk of hospitalization. ConclusionCurrent evidence shows that cognitive frailty can increase the risk of hospitalization and mortality in the elderly. It is suggested that early screening and intervention of cognitive frailty should be carried out to effectively reduce the risk of adverse consequences, so as to achieve healthy aging.
ObjectivesTo investigate the citation status of systematic reviews (SRs)/meta-analyses in clinical practice guidelines and consensuses of traditional Chinese medicine (TCM).MethodsWe electronically searched PubMed, CBM, WanFang Data and CNKI databases to collect TCM guidelines and consensus from January 1st, 2009 to December 31st, 2018. Two reviewers independently screened literature and extracted data. Citation analysis method was used to analyze the citation status of SRs/meta-analysis in TCM guidelines and consensuses.ResultsA total of 142 TCM guidelines and consensuses were included, of which 39 (26.5%) failed to provide relevant citations. Of the 103 (72.5%) TCM guidelines and consensuses providing citations, 48 (34.3%) cited SRs/meta-analyses, and 43 cited outdated SRs/ meta-analyses. Four TCM guidelines and consensuses cited Cochrane reviews. In terms of citations, the average citations of guidelines and consensuses were 35.1 and 42.2, respectively; and the average SRs/meta-analyses citations of guidelines and consensuses were 3.8 and 5.5, respectively.ConclusionsTCM guidelines and consensuses citation report rates and the proportion of citation SRs/meta-analyses still require increase. TCM guidelines developers should strengthen the role and significance of SRs, especially Cochrane reviews, in supporting recommendations.
