An observational study in Early Mobilization and Postoperative Care, sponsored by Ankara Training and Research Hospital. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-14.
Sponsored by Ankara Training and Research Hospital · Observational
This prospective observational cohort study aims to evaluate early mobilization in adult postoperative patients admitted to the intensive care unit (ICU) and to investigate its association with short-term clinical outcomes. Early meaningful mobilization is defined as achieving at least sitting at the edge of the bed (mobilization level ≥4) within the first 24 hours after ICU admission. Patients will be classified according to whether early meaningful mobilization is achieved. The primary objective is to evaluate the association between early meaningful mobilization and prolonged ICU stay. Secondary outcomes include mechanical ventilation requirement and duration, hospital length of stay, need for reintubation, development of delirium, complications occurring during mobilization, and ICU mortality.
This is a prospective observational cohort study involving adult postoperative patients admitted to the intensive care unit (ICU). The study aims to systematically evaluate early mobilization practices and investigate the association between early mobilization and short-term clinical outcomes in postoperative ICU patients.
Mobilization performed within the first 24 hours after ICU admission will be evaluated according to predefined standardized criteria. Mobilization levels will be recorded using a scale ranging from passive movements to independent mobilization. Early meaningful mobilization is defined as achieving at least sitting at the edge of the bed (mobilization level ≥4) within the first 24 hours after ICU admission. Patients will be classified according to whether early meaningful mobilization is achieved.
The primary objective is to evaluate the association between early meaningful mobilization and prolonged ICU stay. Secondary objectives include evaluating its association with the requirement for and duration of mechanical ventilation, hospital length of stay, need for reintubation, development of delirium, complications occurring during mobilization, ICU mortality, and other early clinical outcomes.
Clinical factors potentially associated with the feasibility of early mobilization will also be evaluated. These include age, comorbidities, preoperative functional capacity, type and duration of surgery, APACHE II and SOFA scores at ICU admission, requirement for mechanical ventilation, vasopressor support, and sedation level. In patients who are not mobilized early, potential barriers to mobilization, including hemodynamic instability, respiratory insufficiency, deep sedation, pain, surgical restrictions, and organizational factors, will be recorded.
Patients will be followed throughout their ICU and hospital stay, and relevant clinical outcomes will be recorded. Demographic characteristics, surgical data, clinical parameters at ICU admission, mobilization status, and clinical outcomes will be collected using a standardized data collection form. All collected data will be anonymized for analysis.
No additional intervention or diagnostic test will be performed as part of the study. All study data will be obtained during routine clinical follow-up, directly from included patients, nursing observation forms, and electronic hospital records.
Ankara Training and Research Hospital is the lead sponsor of 48 studies on the registry; 8 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Adult postoperative patients admitted to the intensive care unit of Ankara Training and Research Hospital who meet the predefined eligibility criteria will constitute the study population. Participants will be prospectively evaluated for early mobilization during their ICU stay and followed for the clinical outcomes specified in the study protocol.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Postoperative ICU patients who achieve a mobilization level of ≥4 within the first 24 hours after ICU admission.
Postoperative ICU patients who do not achieve a mobilization level of ≥4 within the first 24 hours after ICU admission.
Prolonged Intensive Care Unit Stay
Prolonged ICU stay will be evaluated according to the duration of ICU hospitalization and compared between patients who achieve early meaningful mobilization and those who do not. Early meaningful mobilization is defined as achieving a mobilization level of ≥4 within the first 24 hours after ICU admission.
