Background and objectiveThe prevalence of falls among older adults living in the community is ~30% each year. The impacts of falls are not only confined to the individual but also affect families and the community. Injury from a fall also imposes a heavy financial burden on patients and their families. Currently, there are different reports on the risk factors for falls among older adults in the community. A retrospective analysis was used in this study to identify risk factors for falls in community-dwelling older adults. This research aimed to collect published studies to find risk factors for falls in community-dwelling older adults.MethodsWe searched for literature from the founding of PubMed, EMBASE, the Cochrane Library, the Web of Science, the China National Knowledge Infrastructure (CNKI), the China Science and Technology Periodicals Database (VIP), and the Wanfang database until September 2022. The studies were selected using inclusion and exclusion criteria. We collected information from relevant studies to compare the impact of potential risk factors such as age, female gender, fear of falling, history of falls, unclear vision, depression, and balance disorder on falls among community-dwelling older adults.ResultsA total of 31 studies were included with 70,868 community seniors. A significant risk factor for falls in the community of older adults was dementia (2.01, 95% CI: 1.41–2.86), age (1.15, 95% CI: 1.09–1.22), female gender (1.52, 95% CI: 1.27–1.81), fear of falling (2.82, 95% CI: 1.68–4.74), history of falls (3.22, 95% CI: 1.98–5.23), vision unclear (1.56, 95% CI: 1.29–1.89), depression (1.23, 95% CI: 1.10–1.37), and balance disorder (3.00, 95% CI: 2.05–4.39).ConclusionThis study provides preliminary evidence that falls among community-dwelling older adults are associated with factors such as age, female gender, fear of falling, history of falls, unclear vision, depression, and balance disorders. The results of this research may help improve clinician awareness, risk stratification, and fall prevention among community-dwelling older adults.Systematic review registrationidentifier INPLASY2022120080.

Background: Catheter-Related Bloodstream Infection (CRBSI) is a common and life-threatening complication of hemodialysis, with high morbidity and mortality. This meta-analysis was performed to analyze the risk factors of CRBSI in patients undergoing hemodialysis. Methods: The search process included the electronic databases of CNKI, WANGFANG, PubMed, EMBASE, the Cochrane Library, and Web of Science from inception to July 2021. The quality assessment of the included studies was conducted according to the Newcastle-Ottawa Scale (NOS). The Odds ratios (ORs) with corresponding 95% confidence intervals (95%CIs) were calculated to assess the strength of the association of risk factors with CRBSI using RevMan 5.4 software in the current study. Results: A total of 23 pieces of literature were included in this study, counting a total of 10335 patients, including 1165 patients with CRBSI and 9170 patients without CRBSI. Meta analysis results showed that puncture times [OR=3.22, 95% CI (2.42, 4.27)], femoral vein catheterization (OR=1.69, 95%CI 1.38-2.08, P＜0.00001), catheter indwelling time (OR = 2.22, 95% CI 1.62-3.04, P < 0.0001), age (OR =1.69, 95%CI 1.49-1.91, P < 0.0001), diabetes mellitus (OR=1.92, 95%CI 1.71-2.15, P< 0.00001), dialysis time (OR = 2.89, 95%CI 1.82-4.59, P <0.0001), duration of hospitalization (OR =2.49, 95%CI 1.47-4.23,P =0.0006) and hypoproteinemia (OR =3.19, 95%CI 2.08-4.89, P＜0.0001) were risk factors for CRBSI.Conclusions: Catheter retention time, age, femoral vein catheterization, diabetes, hospitalization time and hypoproteinemia were risk factors for CRBSI in hemodialysis patients.

Background: Post-extubation dysphagia is high in critically ill patients and is not easily recognized. This study aimed to identify risk factors for acquired swallowing disorders in the intensive care unit (ICU). Methods:We have retrieved all relevant research published before August 2022 from PubMed, Embase, Web of Science, and the Cochrane Library electronic databases. The studies were selected using inclusion and exclusion criteria. Two reviewers screened studies, extracted data, and independently evaluated the risk of bias. The quality of the study was assessed with the Newcastle-Ottawa Scale, and a meta-analysis was carried out with Cochrane Collaboration's Revman 5.3 software.Results: A total of 15 studies were included. Age (odds ratio [OR] = 1.04), tracheal intubation time (OR = 1.61), APACHE II (OR = 1.04), and tracheostomy (OR = 3.75) were significant risk factors that contributed to post-extubation dysphagia in ICU. Conclusion:This study provides preliminary evidence that post-extraction dysphagia in ICU is associated with factors such as age, tracheal intubation time, APACHE II, and tracheostomy. The results of this research may improve clinician awareness, risk stratification, and prevention of post-extraction dysphagia in the ICU.
