Abstract
Objective To screen the prevalence of preoperative cognitive impairment in elderly patients scheduled for elective surgery and to analyze its influencing factors,so as to provide a basis for enhancing perioperative risk management.Methods A cross-sectional survey was conducted using convenience sampling.Elderly patients awaiting elective surgery between July 2023 and June 2024 at a tertiary hospital in Chongqing were enrolled.Data were collected using a self-designed general information question-naire,the Mini-Mental State Examination(MMSE),and eight other standardized scales.Primary assessment indicators included cog-nitive function,activities of daily living(Barthel Index),frailty,nutritional status,swallowing function,anxiety,depression,and pain.Secondary indicators encompassed basic demographics,social support,comorbidities,and medication use.Data were analyzed u-sing multivariate ordinal logistic regression.Results A total of 567 elderly patients were included,with a mean age of(71.81±6.34)years.The overall prevalence of preoperative cognitive impairment was 48.85%,comprising 184 cases(32.45%)of mild cognitive impairment and 93 cases(16.40%)of moderate to severe impairment.Multivariate ordinal logistic regression analysis i-dentified that older age,frailty,and depression were independent risk factors positively associated with the severity of cognitive im-pairment(P<0.05,OR>1).Conversely,self-care ability,nutritional status,and duration of education were independent protective factors,negatively associated with impairment severity(P<0.05,OR<1).Conclusion Preoperative cognitive impairment is highly prevalent and multifactorial among elderly elective surgery patients.It is recommended to integrate routine cognitive screening into perioperative management protocols to facilitate early identification and intervention.关键词
