Chronic Pain and Postoperative Delirium in Geriatric Orthopedic Surgery

200 elderly patients undergoing elective orthopedic surgery were enrolled in a prospective cohort study. The dataset captures preoperative chronic pain status, pain intensity via VAS scores, and postoperative delirium assessments within 7 days using the 3D-CAM tool. It was created by Qianyu Yang to analyze the association between chronic pain and delirium risk.

Use Cases

• Analyze the association between preoperative chronic pain status and postoperative delirium incidence in 200 elderly patients.
• Model the relationship between VAS pain intensity scores and postoperative delirium risk using logistic regression.
• Investigate demographic and perioperative baseline factors as potential confounders in the chronic pain-delirium association.
• Perform subgroup analysis on the 117 chronic pain patients to identify specific risk factors for delirium.

Strengths

• Data from a clearly defined prospective cohort of 200 patients.
• Includes specific clinical metrics: VAS pain scores and 3D-CAM delirium assessments.
• Study results, including odds ratios (e.g., adjusted OR=2.488), are directly reported.

Limitations

• Small sample size of 200 patients limits statistical power for complex subgroup analyses.
• Data is contained in a DOCX file, requiring extraction for computational analysis.
• Geographic and institutional specifics are unknown, limiting generalizability.
