Same-day Hospital Discharge After Minimally Invasive Hysterectomy in a Gynecologic Oncology Practice: Feasibility, Safety, Predictors of Admission, and Adverse Outcomes

Study Objectives: (1) Determine the feasibility and safety of same-day hospital discharge (SDHD) after minimally invasive hysterectomy (MIH) in a gynecologic oncology practice and (2) detail predictors of immediate postoperative hospital admission and multiple 30-day adverse outcomes.

Design: Retrospective cohort study.

Setting: University of Pittsburgh Medical Center Magee-Womens Hospital.

Patients: MIH by a gynecologic oncologist between January 2017 and July 2019.

Interventions: Clinicopathologic, operative, and medical characteristics, as well as 30-day postoperative complications, emergency department (ED) encounters, and hospital readmissions were extracted. Admitted and SDHD patients were compared using descriptive, chi-square, Fisher's exact, t test, and logistic regression analyses. Univariate and multivariable analyses (MVA) revealed predictors of postoperative hospital admission, 30-day readmission, and a 30-day composite adverse event variable (all-reported postoperative complications, ED encounter, and/or readmission).

Measurements And Main Results: A total of 1124 patients were identified, of which 77.3% had cancer or precancer; 775 patients (69.0%) underwent SDHD. On MVA, predictors of postoperative admission included older age, distance from hospital, longer procedure length, operative complications, start time after 2 PM, radical hysterectomy, minilaparotomy, adhesiolysis, cardiac disease, cerebrovascular disease, venous thromboembolism, diabetes, and neurologic disorders (p <.05). Moreover, 30-day adverse outcomes were rare (complication 8.7% National Surgical Quality Improvement Program/11.9% all-reported; ED encounter 5.0%; readmission 3.6%). SDHD patients had fewer all-reported complications (10.3% vs 15.5%, p = .01), no difference in ED encounters (4.6% vs 5.7%, p = .44), and fewer observed readmissions (2.8% vs 5.2%, p = .05). Predictors of readmission were identified on univariate; MVA was not feasible given the low number of events. Longer procedure length and cardiac and obstructive pulmonary disease were predictors of the composite adverse event variable (p <.05).

Conclusion: SDHD is feasible and safe after MIH within a representative gynecologic oncology practice. Clinicopathologic, medical, and surgical predictors of multiple adverse outcomes were comprehensively described. By identifying patients at high risk of postoperative adverse events, we can direct SDHD selection in the absence of standardized institutional and/or national consensus guidelines and identify patients for prehabilitation and increased perioperative support.
