A Prediction Model of Postoperative Anxiety Symptom in Elderly Patients Undergoing Major Noncardiac Surgery

October 13, 2024 updated by: Weidong Mi, Chinese PLA General Hospital

Identification and Validation of a Prediction Model of Postoperative Anxiety Symptom in Elderly Patients Undergoing Major Noncardiac Surgery: a Prospective Multicenter Cohort Study

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Elderly patients (aged ≥ 65 years) who completed the anxiety and depression assessment after the elective major noncardiac, non-neurosurgical surgery were included in this study.

Description

Inclusion Criteria:

  1. Elderly patients (age ≥ 65 years).
  2. Undergoing elective surgery with a planned overnight hospital stay following surgery.
  3. Major non-cardiac surgery, non-neurosurgical surgery.

Exclusion Criteria:

  1. History of previous severe mental illness or long-term use of psychotropic medications.
  2. Immediately admitted to ICU after surgery.
  3. Death within 7 days after surgery.
  4. Grade of surgery ≤ 2.
  5. Failure to complete the postoperative anxiety assessment.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Anxiety
Time Frame: within 7 days after surgery
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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
April 1, 2020

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
