A multicentre, prospective observational study to develop and validate a predictive model for postoperative anxiety symptoms in elderly Chinese patients undergoing non-cardiac major surgery.
In 2015, the WHO introduced the concept of "healthy ageing" for global ageing, with a focus on the mental health of older people at its core. More than 20 million elderly patients undergo surgery each year in China, accounting for a quarter of the population who undergo surgery. Previous studies have found high risk of anxiety in older perioperative patients, especially for non-cardiac major surgery patients. Therefore, it is necessary to construct a predictive model of anxiety in elderly patients undergoing non-cardiac major surgery.

Anxiety
The GAD-7 is a seven-item questionnaire for screening on the presence of generalized anxiety disorder and assessing its severity. Items were scored on a four-point scale with total scores ranging from zero to twenty-one. Scores were defined as: ≥5 mild, ≥10 moderate, and ≥15 severe anxiety. The recommended screening cutoff was ≥10, corresponding with at least a moderate level of anxiety. Higher scores mean more anxiety.
Time frame: within 7 days after surgery
