Summary

This retrospective observational study aims to evaluate short-term postoperative outcomes in older adults undergoing elective minimally invasive surgery. The primary focus is on patient-centered recovery measures, including length of hospital stay and the number of days patients are alive and at home within 30 days after surgery. Using routinely collected clinical data, the study will assess demographic, clinical, and perioperative factors associated with delayed discharge and reduced time spent at home after surgery. Understanding these factors may help clinicians and healthcare systems better plan postoperative care and optimize recovery pathways for older surgical patients.

Detailed description

This is a multicenter, retrospective, observational cohort study designed to identify predictors of short-term postoperative outcomes in older adults undergoing elective minimally invasive surgical procedures. The study includes patients aged 70 years and older who underwent elective laparoscopic or minimally invasive abdominal surgery. All data are derived exclusively from routinely collected medical records generated during standard clinical care. No study-related interventions, changes in clinical management, or additional patient contacts are performed. The primary outcomes of interest are length of hospital stay and days alive and at home within 30 days after surgery (HOME-30 / DAH30). Secondary analyses explore the association of demographic characteristics, comorbidities, perioperative factors, and discharge timing with these outcomes. The study aims to improve understanding of non-medical contributors to prolonged hospitalization in older surgical patients and to support the development of patient-centered outcome measures applicable across different healthcare systems.
