Abstract
Background: Same-day discharge after mastectomy has been demonstrated to be safe in appropriately selected candidates. However, the association between same-day discharge after mastectomy and quality of life (QOL) is unclear. Patient-reported outcome (PRO) measures represent important indicators of QOL among patients undergoing treatment for breast cancer. In this study, we aimed to evaluate the effect of same-day discharge after mastectomy on PROs.
Methods: We performed a retrospective review of a prospectively collected, longitudinal PRO registry of female breast cancer patients treated at an academic breast center between June 2019 and June 2022. Patients were invited to complete the BREAST-Q module, a validated PRO questionnaire measuring QOL domains such as psychosocial wellbeing, physical wellbeing, satisfaction with their surgeon, and satisfaction with their medical team. Preoperative and 2-week postoperative questionnaire responses were analyzed in this study. Patients who had a mastectomy with or without reconstruction were included in this analysis. Those who underwent immediate reconstruction with autologous tissue were excluded as these operations are not conducive to same-day discharge. Patients were divided into two groups: the first was discharged on the date of surgery while the second was admitted to the hospital for a minimum of one night. Clinical and demographic factors were collected from a review of the electronic medical record. The primary endpoints were mean satisfaction scores as well as differences between postoperative and preoperative scores for the psychosocial and physical wellbeing domains. T-tests were used to evaluate differences between groups. A multiple regression model was fit to adjust for the effects of relevant clinical and demographic factors.
Results: A total of 104 patients within the registry underwent mastectomy during the study period and were offered questionnaires. Of these, 58 completed both the preoperative and 2-week postoperative questionnaire (56% response rate); 20 (34%) in the same-day discharge group and 38 (66%) in the inpatient admission group. The groups were similar in age, stage, American Society of Anesthesiologists’ classification group, body mass index, frequency of unplanned readmission or reoperation, and receipt of bilateral mastectomy, axillary lymph node dissection, post-mastectomy reconstruction, and neoadjuvant chemotherapy. Mean patient satisfaction scores and mean changes in psychosocial and physical wellbeing scores were similar between the groups 2 weeks after surgery (Table 1). After controlling for age, type of reconstructive operation, receipt of unplanned reoperation, and preoperative score, same-day discharge did not have a significant effect on satisfaction with the surgeon (Beta=-4.3, p=0.37), satisfaction with the medical team (Beta=0.2, p=0.97), physical wellbeing score (Beta=-0.1, p=0.99), or psychosocial wellbeing score (Beta=8.0, p=0.15).
Conclusions: Patients who are discharged from the hospital on the same day of a mastectomy display similar levels of satisfaction with their care team and similar short-term trends in physical and psychosocial wellbeing compared to those who are admitted to the hospital. While further data are being accrued, these early results suggest patients tolerate same-day discharge after mastectomy well.
