Funktionel kapacitet og dage i live ude af hospitalet efter 30 dage

2. november 2026 opdateret af: Muserref Beril Dincer, Istanbul University

Evaluering af dage i live og ude af hospitalet efter 30 dage hos patienter med dårlig eller god funktionsevne, der gennemgår gastrointestinal kirurgi

This prospective observational study aims to compare days alive and out of hospital at 30 days (DAOH-30) in patients with poor or good functional capacity undergoing gastrointestinal surgeries. The investigators are testing the hypothesis that patients with good functional capacity will have longer days alive and out of hospital than those with poor.

Detaljeret beskrivelse

Days Alive and Out of Hospital (DAOH) is a composite patient-centered outcome that integrates three critical clinical outcomes: death, hospital length of stay, and hospital readmission. It is associated with patient comorbidities, surgical complexity, and postoperative complications.

Evaluation of functional capacity before noncardiac surgery is recommended to identify the perioperative risks. Duke Activity Status Index (DASI) is one of the tools for determining functional capacity; the scores are between 0 and 58,2, and high scores are related to improved capacity. A DASI score of 34 and below was found to be a risk for moderate to severe complications and new disability.

The primary aim is to compare days alive and out of the hospital at 30 days in patients ≤ 34 and above 34 DASI scores. The secondary aims are to evaluate intensive care unit (ICU) need and duration, length of hospital stay, rehospitalization, postoperative complications, morbidity, and mortality in patients with DASI scores ≤ 34 and above 34. Days alive and out of hospital at 90 days will be compared in both groups as a secondary outcome. The investigators will also analyze the possible perioperative factors affecting the days alive and out of the hospital outcome.

Before the operation, the patients will answer the DASI questionnaire in the waiting area of the operating theatres. The patients will be divided into two groups according to the DASI score (Poor functional capacity: ≤ 34 points, good functional capacity: above 34 points).

Patient and surgical characteristics (comorbidities, American Society of Anesthesiologists physical status classification, laboratory values before the operation, frailty index value, American College of Surgeons Risk Calculator outcomes, surgery type, length of operation, intraoperative complications), ICU need and duration will be recorded. Postoperative complications ( cardiovascular, pulmonary, renal, neurologic, surgical, infectious, and wound ), the Postoperative Morbidity Survey (POMS) related morbidity and mortality on the 30th day will be investigated. Length of hospital stay starting with index surgery, rehospitalization and duration of further stays will be recorded. Days Alive and Out of Hospital at 30 days (DAOH-30) will be calculated using mortality, hospital length of stay, and readmissions between the date of the index surgery and the 30th postoperative day. 90th-day mortality and Days Alive and Out of Hospital at 90 days (DAOH-90) will also be investigated.

Kohorter og interventioner

Gruppe / kohorte
Intervention / Behandling
Group DASI ≤ 34

Patients with Duke Activity Status Index (DASI) scores are ≤ 34 before the surgery.

All patients will answer the DASI questionnaire before surgery. According to their scores, they will be divided into two groups. A score of 34 and below will be considered poor, and above 34 will be considered to have good functional capacity.

Group DASI > 34

Patients with Duke Activity Status Index (DASI) scores are > 34 before the surgery.

All patients will answer the DASI questionnaire before surgery. According to their scores, they will be divided into two groups. A score of 34 and below will be considered poor, and above 34 will be considered to have good functional capacity.
