NCT07377812

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Days Alive and at Home Within 30 Days After Surgery (DAH30)

    Days Alive and at Home within 30 days after surgery (DAH30), defined as the total number of days during the first 30 days following the index surgical procedure that the patient is alive and not admitted to an acute care hospital.

    Postoperative Day 0 through Postoperative Day 30

Secondary Outcomes (4)

  • Length of Hospital Stay After Surgery

    Perioperative period

  • All-Cause Hospital Readmission Within 30 Days After Surgery

    Postoperative Day 1 through Postoperative Day 30

  • Postoperative Complications Within 30 Days

    Postoperative Day 0 through Postoperative Day 30

  • Discharge Destination After Surgery

    Perioperative period
