What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07532122). This is a study registration, not published results. Lead sponsor: Chinese PLA General Hospital. Recruitment status: COMPLETED. Study type: OBSERVATIONAL. Enrollment: 7568 participants (ACTUAL). Conditions: Depression, Anxiety. Primary outcome measures: Depression , within 7 days after surgery; Anxiety , within 7 days after surgery. Brief summary: The goal of this observational study is to learn about the prevalence of postoperative anxiety and depression symptoms and identify the related risk factors in elderly patients aged 65 and older who undergo non-cardiac surgery in China. The main questions it aims to answer are: What is the prevalence rate of postoperative anxiety symptoms in elderly Chinese patients after non-cardiac surgery? What is the prevalence rate of postoperative depression symptoms in elderly Chinese patients after non-cardiac surgery? What are the risk and protective factors linked to postoperative anxiety and depression symptoms in this patient population? Participants will undergo routine non-cardiac surgery as part of their standard medical care, and researchers will collect relevant clinical data and assess their anxiety and depression symptoms using standardized screening scales after surgery.
