ABCDEF Bundle Compliance and ICU Outcomes in Latin America

20 августа 2026 г. обновлено: Jose J Zaragoza, MD MSc, Hospital H+ Queretaro

ABCDEF Bundle Compliance and Outcomes in Latin American Intensive Care Units: An International Multicenter Prospective Observational Study

The goal of this observational study is to evaluate the degree of compliance with the ABCDEF bundle and its relationship with clinical outcomes in adult patients (aged 18 and older) admitted to intensive care units (ICUs) in Latin America for at least 48 hours.

The main questions it aims to answer are: What is the prevalence, cumulative incidence, and duration of delirium in adult ICU patients in Latin America? Is higher compliance with the ABCDEF bundle (low [<33%], moderate [33%-66%], high [>66%]) independently associated with a lower prevalence, cumulative incidence, and duration of delirium? Does higher ABCDEF bundle compliance improve functional mobility at hospital discharge and long-term cognitive, psychological, and quality-of-life outcomes at 3 and 6 months post-discharge? Researchers will compare three groups based on their level of ABCDEF bundle compliance (low [<33%], moderate [33%-66%], and high [>66%]) to see if higher bundle adherence improves delirium and long-term post-ICU functional outcomes.

Participants will:

Receive standard ICU care without experimental intervention. Undergo daily assessments for delirium (using CAM-ICU) and physical mobility (using ICU Mobility Scale) during their ICU stay.

Complete telephone follow-up evaluations at 3 months post-discharge to assess cognitive function (BCAT-ICU/MoCA) and psychological symptoms (HADS, DSPS).

Complete follow-up evaluations at 6 months post-discharge to assess cognitive function (full MoCA), psychological symptoms (HADS, DSPS), and health-related quality of life (EQ-5D-5L).
