Abstract: Objective To systematically evaluate the status of dysphagia in patients with acute stroke. Methods PubMed, EMbase, Web of Science, The Cochrane Library, Chinese Biomedical Literature Database(CBM), VIP, CNKI, WanFang and other databases were used to search literatures on the detection rate of dysphagia in patients with acute stroke from the establishment of the database to November 5, 2021. Two nursing researchers independently screened the retrieved literatures according to the inclusion and exclusion criteria, extracted data, and evaluated the bias risk of the included literatures. Then Stata16 software was used for Meta analysis. Results A total of 29 articles were included, including 26799 subjects. The prevalence of dysphagia in acute stroke patients was 53%(95%CI:0.46-0.60). Subgroup analysis showed 20% of males(95%CI:0.17-0.22)and 20% of females(95%CI:0.17-0.24). The detection rates were 6%(95%CI:-0.03-0.15)in patients under 50 years old, 9%(95%CI:0.04-0.15)in patients 50 to 59 years old, 26%(95%CI:-0.04-0.56)in patients 60 to 69 years old, 29%(95%CI:0.03-0.54)in patients aged 70-79 years, and 39%(95%CI:-0.24-1.03)in patients aged 80 years or older. The prevalence of dysphagia in cerebral stem, cerebellum, cerebellum, brainstem + cerebellum and brainstem + hemisphere stroke patients was 39%, 13%, 21%, 33% and 90% respectively. The detection rates of swallowing disorders in patients with total anterior circulation infarction(TACI), partial anterior circulation infarction(PACI), posterior circulation infarction(POCI)and lacunar infarction(LACI)were 58%, 25%, 26% and 16% respectively. The prevalence of dysphagia in patients with cardiogenic stroke, large vessel occlusion, small vessel occlusion and atherosclerosis was 18%, 14%, 9% and 14% respectively. The prevalence of dysphagia in patients with hypercholesterolemia, hypertension, smoking, diabetes, atrial fibrillation and hyperlipidemia were 19%, 22%, 19%, 22%, 22% and 10% respectively. The prevalence of dysphagia in hypertension, diabetes, smoking and drinking was 28%, 27%, 38% and 16% respectively. Conclusion The rate of dysphagia in acute stroke patients is high. However, due to the limitations of the quality and quantity of the included literatures, the above conclusions still need to be verified by incorporating higher-quality literatures.
