Safety of robotic-assisted gynecologic surgery and early hospital discharge in elderly patients

BACKGROUND: A minimally invasive surgical approach has proven to decrease peri-and postoperative complications and shorten duration of hospital stay; however, there are limited data evaluating the safety of robotic-assisted surgery and early hospital discharge in the elderly population. Because age is a well-known, independent risk factor for perioperative morbidity and gynecologists treat many elderly patients, this is an important area of study. OBJECTIVE: The objective of the study was to evaluate discharge timing and surgical outcomes in elderly compared with younger patients undergoing robotic-assisted gynecologic surgery. STUDY DESIGN: This was a retrospective cohort study of all patients who underwent robotic-assisted gynecologic surgery at a high-volume, single institution from January 2013 through May 2016. Demographic information, discharge timing, and peri-and postoperative outcomes were compared for patients <65 years with those >= 65 years using univariate and multivariate analyses. RESULTS: There were 2757 patients included, with 2521 <65 years and 236 >= 65 years. Median age of the younger group was 42 years, while the median age of the elderly group was 69 years. Elderly patients had a higher body mass index (kilograms per square meter) (28 vs 26, P <. 001) and higher American Society of Anesthesia classification (P < .001). Elderly were more likely to have malignancy as the indication for surgery (68% vs 11%, P<.001) and to undergo hysterectomy (81% vs 38%, P<.001) or surgery with lymph node dissection (44.5% vs 7.1%, P < .001). Elderly patients had a higher incidence of intraoperative complications (9% vs 4.6%, P = .002) and longer median hospital stay (17 vs 7 hours, P <.001) compared with younger patients. Same-day discharge was more common in younger patients (76% vs 45%, P < .001), and elderly patients were more likely to have admissions lasting >23 hours (13% vs 3%, P < .001) on univariate and multivariate analysis. Analysis of postoperative outcomes included 2023 patients with available postoperative data (80% of total population) (1794 < 65 years, 229 >= 65 years). There were no differences between elderly and younger patients in overall postoperative complications, reoperations, intensive care unit admissions, emergency room visits, or hospital readmission within 6 weeks of surgery. CONCLUSION: Despite having more preoperative risk factors and more surgically complex procedures, elderly patients undergoing robotic-assisted gynecologic surgery had similar postoperative complication rates, and almost half of elderly patients were safely discharged the day of surgery. Our data suggest that robotic-assisted gynecologic surgery and early hospital discharge are safe in elderly patients.
