Background:
Autologous free tissue transfer is a common method of breast reconstruction in the United States, but it involves many care teams and can incur a large cost on an institution. The consistency and efficiency of performing these procedures can be improved with a method called the 4 disciplines of execution (4DX).
Methods:
Patients that underwent autologous breast reconstruction between 2015 and 2020 were included. Midway through the collection period, several preoperative and intraoperative interventions were implemented using the 4DX. Then, 2 cohorts of patients were analyzed for differences in operative times, length of stay (LOS), and major complications.
Results:
Thirty-two total patients were included. The median operative time before interventions were implemented was 828 minutes, and the median operative time after interventions was 619 minutes (P < 0.05). The median LOS in days before interventions was 5 days, and the median LOS after interventions was 3 days (P < 0.05). There were no statistically significant differences in complications before or after the interventions.
Conclusions:
The 4DX successfully improved consistency and efficiency in the process of performing autologous breast reconstruction at our institution, as evidenced by a faster median operative time and shorter patient LOS in the hospital.
