Wearable Device Tracked Recovery From Autologous Breast Reconstructive Surgery

Primary Objectives: The primary objective of \[SH1.1\]\[PH1.2\]this study is to determine the time until return to baseline physical activity following DIEP flap breast reconstruction, as measured by the participant's average daily preoperative step count using the Fitbit Inspire 3 wearable device. Return to baseline is defined as a 7-day rolling average of daily steps reaching at least 95 percent of the patient's preoperative baseline step average. This objective seeks to establish an objective, quantifiable recovery metric that can serve as a benchmark for postoperative functional recovery in autologous breast reconstruction. Secondary Objectives: * Assessing the feasibility and adherence of continuous wearable data collection before and after DIEP flap surgery, including wear time and data completeness. * Evaluating perioperative trends in heart rate and sleep parameters, and their relationship to overall recovery patterns. * Exploring associations between wearable-derived recovery metrics (e.g., activity and sleep) and short-term clinical outcomes such as wound complications, seroma, hematoma, DVT/VTE, readmission, and length of stay. * Comparing wearable activity tracker data with patient-reported activity levels to evaluate agreement between objective and subjective recovery measures. * Characterizing baseline lifestyle factors - specifically music listening time, active music engagement, and live concert attendance (Gold-MSI Active Engagement subscale) - and exploring their associations with time to return-to-baseline activity, perioperative sleep parameters, and patient-reported outcomes.
