结局指标
主要结局
Patient-reported physical well-being and breast symptoms
时间窗: 12 Months
Patient-reported physical well-being and breast symptoms will be evaluated using the Breast Quality of Life Physical Well-Being and Breast Symptoms scales. Values are scores from 0 to 100, with higher scores indicating better satisfaction or quality of life for patients undergoing breast surgery, such as those with breast cancer. These scores are derived from patient-reported outcome measures across different domains like satisfaction with breasts, psychosocial well-being, physical well-being (chest and abdomen), and sexual well-being.
Brief Pain Inventory (BPI) Scoring
时间窗: 12 Months
The BPI is a self-report questionnaire that assesses pain intensity and interference. It consists of two parts: Pain Severity: Measures the intensity of pain using a 0-10 scale, where 0 is "no pain" and 10 is "worst possible pain." Pain Interference: Measures how much pain interferes with daily activities using a 0-10 scale for seven items (e.g., general activity, mood, sleep). Calculation of Scores: Pain Severity Score: Add up the scores for the four pain severity questions (worst pain, least pain, average pain, current pain) and divide by 4. Pain Interference Score: Add up the scores for the seven pain interference questions and divide by 7. Interpretation: Pain Severity: 0-3: Mild pain 4-6: Moderate pain 7-10: Severe pain Pain Interference: Higher scores indicate greater interference with daily activities.
