Safety of Same-Day Discharge Versus Hospital Admission in Minimally Invasive Myomectomy

Study Objective To compare postoperative complication rates between same-day discharge patients and patients admitted to hospital after minimally invasive myomectomy, stratified by patient demographics and perioperative variables including myoma burden. Design Retrospective cohort study. Setting Hospitals participating in the National Surgical Quality Improvement Program database from January 2015 to December 2019. Patients Female patients aged ≥18 years undergoing minimally invasive myomectomy. Interventions Patients were categorized into either the same-day discharge or admitted patient cohort. Univariate comparisons of demographics, perioperative variables, and 30-day postoperative complications were performed. Multivariate logistic regression was used to 1) identify demographic and perioperative factors associated with admission, and 2) compare postoperative complication rates of same-day discharge patients with those of admitted patients while adjusting for demographic and perioperative factors. Measurements and Main Results Eight thousand one hundred patients were recruited during the study period. The overall rate of same-day discharge was 57.2% in 2015 and 65.0% in 2019. The same-day discharge rate was 64.6% for patients with a smaller myoma burden (1–4 fibroids and ≤250 grams, Current Procedural Terminology 58545) and 56.8% for larger myoma burden (≥5 fibroids or >250 grams, Current Procedural Terminology 58546). Age, race, American Society of Anesthesiologists classification III or IV, preoperative hematocrit <36%, hypertension, diabetes, bleeding disorder, and increasing operative time were associated with admission to hospital. After adjusting for these variables, composite postoperative complication rates were similar between admitted patients and patients who were discharged the same day regardless of myoma burden (adjusted OR [aOR], 0.66; 95% confidence interval [CI] 0.18–2.47 for low myoma burden and aOR, 0.91; 95% CI 0.18–4.63 for high myoma burden). Admitted patients with both low (aOR, 9.1; 95% CI 2.27–37.04) and high (aOR, 8.24; 95% CI 1.59–42.49) myoma burdens were significantly more likely to receive a blood transfusion compared to same-day discharge patients. Conclusion Same-day discharge after minimally invasive myomectomy, regardless of myoma burden, is associated with low complication rates. Our findings may aid in shared decision making on discharge planning.
