Preoperative depression is an independent risk factor for short-term morbidities in autologous and implant-based breast reconstruction.

[BACKGROUND] Depression is notably common among patients who have undergone mastectomy. Several post-mastectomy patients opt for elective breast reconstruction. However, evidence on the influence of preoperative depression on breast reconstruction outcomes remains limited. This study aimed to evaluate the effect of preoperative depression on the short-term outcomes of autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR) using a comprehensive national registry.

[METHODS] Patients who underwent ABR or IBR were identified from the national inpatient sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between the patients with and without depression, adjusted for demographics, primary payer status, hospital characteristics, and comorbidities.

[RESULTS] Among the 12,984 patients who underwent ABR, 1578 (12 %) had depression whereas 1980 (11 %) out of 17,963 patients who underwent IBR had depression. In ABR and IBR, preoperative depression was associated with higher superficial wound complications (ABR, aOR = 1.386, 95 % CI = 1.035-1.856, p = 0.03; IBR, aOR = 1.281, 95 % CI = 1.001-1.638, p = 0.04), hemorrhage/hematoma (ABR, aOR = 1.164, 95 % CI = 1.010-1.355, p = 0.04; IBR, aOR = 1.614, 95 % CI = 1.279-2.037, p < 0.01), and longer hospital length of stay (p < 0.01). In ABR, patients with depression had higher incidences of infection (aOR = 1.906, 95 % CI = 1.246-2.917, p < 0.01) and sepsis (aOR = 15.609, 95 % CI = 1.411-172.65, p = 0.03). In IBR, patients with depression had higher risks of capsular contracture (aOR = 1.477, 95 % CI = 1.105-1.976, p = 0.01) and seroma (aOR = 1.489, 95 % CI = 1.005-2.208, p = 0.04).

[CONCLUSION] Preoperative depression is independently associated with major morbidities after ABR and IBR. Preoperative screening for depression can be beneficial. Findings from this study can facilitate preoperative risk stratification and post-operative care for patients with depression.
