National Patterns of Hospital Admission Versus Home Recovery Following Mastectomy for Breast Cancer.

Abstract

Background: We examined national patterns of care and perioperative outcomes for women after mastectomy, comparing home recovery (HR) with hospital admission.

Patients and methods: Using Martketscan data (2017-2019), women ≥ 18 years old who underwent mastectomy ± reconstruction were identified and classified as either home recovery (same calendar day discharge) or hospital admission (stays > 1 calendar day). Comorbidities and receipt of chemo/immunotherapy 6 months prior to surgery and post-surgical 30-day complications were measured. Logistic regression calculated the odds of any complication by encounter type, adjusting for age, accompanying lymph node (LN) procedure, reconstruction, neoadjuvant chemo- and/or immunotherapy, and select comorbidities.

Results: Of 11,789 mastectomy encounters (N = 11,659 women), 4751 (40%) cases utilized HR while 7038 (60%) had hospital admission. HR patients were older (53.6 years old vs. 51.8 years old) with lower rates of reconstruction (60.2 vs. 74.5%, p < 0.001). Rates of neoadjuvant chemotherapy (19.6 vs. 20.9%, p = 0.099) and immunotherapy (3.6 vs. 3.9%, p = 0.445) were similar between groups. Complication rates were lower among HR patients with fewer postoperative hematomas (0.6 vs. 1.3%, p < 0.001) and decreased wound complications (8.5 vs. 9.8%, p = 0.019). In a multivariable analysis, the odds of any complication were approximately 20% lower for HR patients compared with admission patients (aOR 0.81, 95% CI 0.72-0.91, p < 0.001). Unplanned emergency room visits were similar between groups (6.7 vs. 7.2%, p = 0.374); yet fewer hospital re-admissions (2.5 vs. 3.5%, p = 0.003) occurred in women recovering at home.

Conclusion: HR is a safe option compared with in-hospital admission for clinically appropriate women after mastectomy as they are less likely to experience postoperative complications, emergency department (ED) visits, or hospitalization.
