The incidence of PI in the study group (4.62%) was lower than that of the control group (22.03%), and the area of PI in the study group was smaller than that of the control group (all P<0.05). Compared to the control group, the scores of self-rating anxiety scale and self-rating depression scale in the study group were substantially lower (all P<0.05). The study group had lower total incidence of complications (3.08% vs. 20.34%) and higher total satisfaction (95.38% vs. 79.66%) than the control group (all P<0.05).</p><p><strong>Conclusion: </strong>Graded nursing based on the risk early warning concept is highly effective in managing long-term bedridden patients. It reduces the occurrence of PI and complications, shortens the turnover interval time and the time to first out-of-bed activity, improves activities of daily living and motor function as well as quality of life, relieves negative emotions, and improves patient satisfaction.</p>","PeriodicalId":7731,"journal":{"name":"American journal of translational research","volume":"16 10","pages":"5454-5465"},"PeriodicalIF":1.7,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11558442/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142612079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
