Changes in FOIS scores and caregiver guilt were assessed using the Wilcoxon signed rank test and McNemar test, respectively. The impact of oral intake changes on caregiving motivation was assessed using the Fisher exact test.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Between August 2019 and January 2021, 55 of 100 targeted caregivers responded (median age=64.5 years). A significant difference in FOIS scores was found (median rehabilitation duration=9.7 months). Despite 25 pneumonia cases, 65% of the caregivers continued to encourage oral intake. Guilt decreased from 48% during peak dysphagia to 22% at survey time (odds ratio=0.2, 95% CI=0.04–0.70; <i>P</i> &lt; 0.01). No association was found between caregiving motivation and improved oral intake.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Severe dysphagia impacted caregiver well-being, indicating preferences for patients' oral intake. To support caregivers, healthcare professionals should explore and integrate new multidisciplinary approaches into dysphagia rehabilitation strategies.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16668,"journal":{"name":"Journal of Parenteral and Enteral Nutrition","volume":"48 7","pages":"818-826"},"PeriodicalIF":3.2,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142017838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
