About this study
Official title: Predictors of Length of Stay and Days Alive and at Home Within 30 Days (DAH30) After Elective Minimally Invasive Surgery in Older Adults: A Multicenter Retrospective Observational Study With International External Validation
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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Postoperative Day 0 through Postoperative Day 30
Secondary outcomes (4)
Length of Hospital Stay After Surgery
Length of hospital stay, defined as the number of days from the date of surgery to the date of discharge from the index hospitalization.
Measured: Perioperative period
All-Cause Hospital Readmission Within 30 Days After Surgery
Any unplanned hospital readmission for any cause occurring within 30 days after discharge from the index surgical hospitalization.
Measured: Postoperative Day 1 through Postoperative Day 30
Postoperative Complications Within 30 Days
Occurrence of postoperative complications within 30 days after surgery, classified according to the Clavien-Dindo grading system.
Measured: Postoperative Day 0 through Postoperative Day 30
Discharge Destination After Surgery
Discharge destination following index hospitalization, categorized as home, rehabilitation facility, skilled nursing facility, or other healthcare institution.
Measured: Perioperative period
