INTRODUCTION  Enhanced Recovery After Surgery (ERAS) protocols have decreased postoperative opioid consumption and hospital length of stay in deep inferior epigastric perforator (DIEP) flap breast reconstruction. We aim to evaluate whether there needs to be further adjustments to best improve outcomes specifically in patients with a preexisting psychiatric condition. METHODS  A retrospective review was performed of all patients that underwent DIEP flap breast reconstruction between October 2018 and September 2020. This includes all patients with the most recent ERAS protocol implementation of intraoperative transverse abdominal plane blocks with liposomal bupivacaine. We looked at patients with a psychiatric diagnosis at the time of surgery. Specifically, forms of depression and anxiety were the psychiatric diagnoses for these patients. We divided these patients into three groups: those with no diagnoses, those with a single diagnosis, and those with both diagnoses. Primary outcomes observed were postoperative opioid consumption and length of stay. A one-way analysis of variance determined whether there was a difference between the three groups and a Tukey post hoc analysis made pairwise comparisons. A p-value of < 0.05 was significant. RESULTS  A total of 176 patients were analyzed in this study: 59 (33.5%) of our study population had a diagnosis of either depression, anxiety, or both. Postoperative opioid consumption was higher in patients with a psychiatric diagnosis compared with those without (123.8 to 91.5; p < 0.0005). A multiple regression model consisting of operating time, hospital length of stay, whether the patient has a psychiatric diagnosis, and history of chemotherapy statistically significantly predicted opioid consumption (p < 0.0005). CONCLUSION  With similar hospital length of stay postoperatively, it is notable that patients with a psychiatric diagnosis had significantly higher amounts of postoperative opioid consumption. This study highlights the need to further improve multidisciplinary integrated care for patients with psychiatric comorbidities to improve pain management postoperatively.
