Data for"Association Between Preoperative Sleep Disorders and Chronic Postoperative Pain in Hysterectomy Patients: A Prospective Cohort Study"

This dataset contains individual-level data from a prospective cohort study investigating the association between preoperative sleep disorders and chronic postsurgical pain. A total of 275 patients were stratified into two groups based on preoperative sleep quality scores: a no sleep disorders group （n=145）and a sleep disorders group（n=130）, with subsequent follow-up evaluations conducted to assess pain outcomes.

This dataset originates from a prospective cohort study that enrolled 275 women aged 18 to 65 years, scheduled for elective hysterectomy at a single center, in accordance with predefined inclusion and exclusion criteria. Data1 includes preoperative information such as baseline characteristics (sex, age, body mass index, underlying diseases, and surgical history), pain intensity (Numeric Rating Scale, NRS) and sleep quality (Pittsburgh Sleep Quality Index, PSQI), as well as postoperative acute pain scores, chronic pain assessments, and analgesic usage. Data2 contains detailed PSQI component scores related to sleep quality. Data3 comprises perioperative hemodynamic measurements of the patients.

All data have been fully de-identified: only study identification numbers and group labels are provided, with no personal identifiers such as names, dates of birth, or contact information included. All variables, units, and coding schemes are clearly annotated to facilitate data reuse and replication of analyses reported in the associated publication.
