Summary

Sleep quality is a key physiological factor influencing immune function, inflammatory response, and pain perception. This prospective observational study aims to evaluate whether preoperative sleep quality predicts postoperative inflammation, pain severity, and analgesic consumption in patients undergoing elective breast cancer surgery.

Preoperative sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI). Systemic inflammatory response will be evaluated using the Systemic Immune-Inflammation Index (SII), calculated from routine hematological parameters. Postoperative pain will be assessed using the Visual Analog Scale (VAS), and analgesic consumption will be recorded within the first 24 hours.

The study aims to determine whether poor sleep quality is associated with increased inflammatory response, higher pain scores, and greater analgesic requirement.

Preoperative Sleep Quality Assessment (PSQI)

Preoperative sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), a validated self-reported questionnaire evaluating sleep quality over the previous month. Based on PSQI scores, patients will be categorized into two cohorts: good sleep quality (PSQI ≤ 5) and poor sleep quality (PSQI \> 5). No intervention or modification to standard clinical care will be applied. All perioperative management will be conducted according to routine institutional protocols. This study is purely observational, and the PSQI assessment is used solely for grouping and analytical purposes.
