  • ERAS protocols are associated with decreased postoperative stays, reduced opioid use, lower rates of postoperative nausea and vomiting, and lower overall costs to institutions and healthcare systems
  • The aim of this study was to evaluate the impact of an ERAS approach on mastectomy with implant-based subpectoral reconstruction (IBR) with respect to procedure cost and 30-day complication rates for both ambulatory surgery patients and patients hospitalized overnight


Study Type: Retrospective chart review analysis

Subjects: Patients over age 18 undergoing nipple-sparing mastectomy or skinsparing mastectomy with subpectoral IBR at a single institution.

Study Cohorts:

● ERAS: same-day surgery at an ambulatory surgical center

● Overnight hospital admission control group

● Surgeries performed by 2 breast surgeons and 3 plastic surgeons

Analysis Plan:

● ERAS compared to control group, divided by surgical modality (nipple sparing vs. non-nipple sparing mastectomy)

● Demographics, comorbidities, 30-day complications, and cost analyses were examined.

● Direct costs were defined as patient-specific costs, such as pharmacy costs, and radiology charges. Indirect costs included a facility-derived multiplier added to the encounter to cover fixed expenses such as salaried labor, and building overhead.


● There were no significant differences in 30-day complication rates between patients whose mastectomy with reconstruction procedure was at an ambulatory surgical center (utilizing our ERAS protocol) and patients whose operation was at a hospital facility with a planned overnight admission.

● Social factors were the main determinant for identifying those patients who could be safely discharged from an ambulatory setting from those requiring a planned admission.

● On average, a 30% cost saving can be expected with the application of ERAS principles and a same-day surgery approach.
