RESUMO
BACKGROUND: This study examined the effects of an enhanced recovery program on inpatient opioid requirements and hospital length of stay (LOS) for mastectomy patients undergoing immediate reconstruction. METHODS: An enhanced recovery program for patients undergoing mastectomy with immediate tissue expander (TE) or implant reconstruction was evaluated by comparing a contemporary cohort of 611 patients in 2016-2018 with a historical cohort of 188 patients in 2010. Opioid use and LOS were compared over time and stratified by laterality, mastectomy type, axillary procedure, and reconstruction. Associations were assessed by uni- and multivariate analyses. RESULTS: In 2010, 95.2% of patients required intravenous (IV) opioids, with a last dose 15.5 h after completion of surgery, compared with 68.7% of patients in 2016-2018, with a last dose 1.8 h after surgery (p < 0.001). Patients prescribed gabapentin postoperatively were less likely to require inpatient IV or oral opioids (p < 0.001). The mean LOS decreased from 37 h in 2010 to 27.5 h in 2016-2018 without an increase in the readmission rate (6.9% vs. 4.1%; p = 0.112). Patients were more likely to stay more than one night if they were older (p = 0.012), had undergone bilateral mastectomies (p < 0.001) or TE reconstruction (p = 0.012), and had surgery in 2010 compared with 2016-2018 (p < 0.001). Even after adjustment for LOS, IV opioid use remained significantly associated with year of surgery (p < 0.001). CONCLUSIONS: Compared with 2010, patients undergoing mastectomy with TE or implant reconstruction in 2016-2018 required less inpatient opioids and had decreased LOS. The authors attribute this to an enhanced recovery program focused on preoperative counseling, non-opioid analgesics, and improved surgical efficiencies.
