To investigate the association between the New Early Warning Score (NEWS) and 28-day mortality in patients with severe fever with thrombocytopenia syndrome (SFTS).
A cross-sectional derivation and validation study.
A total of 382 SFTS patients were included in retrospective and prospective studies. The primary outcome was short-term (28-day) mortality. Cox regression, receiver operating characteristic (ROC), and Kaplan–Meier analysis were utilised in the retrospective study to assess the association between NEWS and mortality. The prospective study assessed the applicability of the NEWS.
This study was reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.
Among 219 SFTS patients in the retrospective study, 27 (12.3%) died within 28 days. NEWS was significantly higher in non-survivors than in survivors (4.00 [1.00, 5.00] vs. 1.00 [1.00, 2.00]). The ROC curve for MEWS predicting 28-day mortality showed an area under the curve (AUC) of 0.757 (95% confidence interval: 0.65–0.87), with a cut-off of 3.5 (sensitivity: 90.6%; specificity: 55.6%). SFTS patients were stratified into low (NEWS < 4), medium (NEWS 4–6), and high (NEWS > 6) risk groups. Kaplan–Meier analysis showed significantly lower survival rates in medium and high risk groups compared to the low risk group. The prospective study included 63 SFTS patients, of whom 11 (17.5%) died. 28-day mortality significantly increased across NEWS categories: [low risk (4/50, 8.0%), medium risk (4/8, 50.0%), high risk (3/5, 60.0%)].
NEWS was a quicker, simpler, and valuable parameter to identify SFTS patients at risk of 28-day mortality.
An elevated NEWS at admission is associated with a higher risk of poor short-term prognosis in SFTS patients. Incorporating NEWS into emergency nursing practice may aid in the early identification of SFTS patients at risk of adverse prognosis.
Emergency nurses performed the NEWS for the SFTS patients at admission.
To comprehensively synthesise existing evidence from systematic reviews regarding the effects of exercise interventions on physical, psychological and social outcomes in frail older adults to provide reference for clinical practice.
Frailty is highly prevalent in older adults and associated with increased adverse health outcomes. Some systematic reviews have assessed the effectiveness of exercise interventions in frail older adults with varied inclusion criteria, methodology quality, types of exercise and outcome measures.
An overview of systematic reviews reported following the PRISMA checklist.
PubMed, Embase, CINAHL, Web of Science and Cochrane database were searched from inception until June 2023 to identify relevant systematic reviews with or without meta-analysis of randomised controlled trails. Two reviewers independently selected articles, extracted data, assessed quality and summarised findings.
A total of 17 systematic reviews were included, with methodology quality varying from moderate to critically low. The most frequent types of exercise were multicomponent exercise and resistance-based exercise in community and long-term care facilities, respectively. Exercise interventions had positive effects on most physical outcomes and depression, but inconsistent effects on cognitive function and quality of life. The quality of the evidence for most outcomes was low and very low.
This overview highlights the importance of exercise interventions to improve physical, psychological and social aspects in frail older adults and provides evidence on characteristics of exercise interventions for frailty in various settings.
Multicomponent exercise and resistance-based exercise should be recommended for frail older adults. There is a need of more well-designed research with large sample size and validated definition of frailty. Long-term effects, adherence during and after exercise interventions, adverse events and cost-effectiveness should be emphasised in future studies.
The overview protocol was registered on the International Prospective Register of Systematic reviews (CRD 42021281327).
No patient or public contribution.
The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were applied to report the results.
