Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Intensive Care Units (ICU) stabilize and maintain vital functions in critically ill patients, optimizing their survival. However, patients with prolonged stays may develop Post-ICU syndrome , characterized by physical, cognitive and psychological dysfunctions. This syndrome considerably affects the quality of life of patients. The risk of post-ICU syndrome is associated with factors such as advanced age, delirium, prolonged sedation and mechanical ventilation.

The main objective of this study is to assess the temporal evolution of post-ICU syndrome in patients who required mechanical ventilation for more than 48 hours, analyzing its incidence, associated risk factors and the impact on their long-term quality of life.

This cross-sectional study evaluates the presence of post-ICU syndrome in 2025 in patients who have been admitted to the ICU during 2021 and 2024 who required invasive mechanical ventilation for more than 48 hours. Of this total, deceased persons, those who did not give their consent, and minors will not be included.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Advances in intensive care have improved short-term survival rates, but survivors of prolonged ICU stays may face medium- and long-term morbidities, influenced by both the critical illness and the ICU environment. This highlights the importance of a comprehensive approach to their care, focused on improving post-ICU quality of life.

Post-intensive care syndrome is defined as the appearance or worsening of physical, cognitive and/or mental health impairments in patients who survive a stay in an ICU. This syndrome usually manifests during the first 48 hours after admission or after discharge, persisting in the long term and negatively affecting quality of life and daily functionality. In the physical field, is characterized by acquired neuromuscular weakness that frequently limits the patient's autonomy. Regarding psychological dysfunction, disorders such as anxiety, depression and post-traumatic stress disorder are observed; in the neurocognitive field, dysfunctions in memory, attention and executive functions affect daily life. This syndrome considerably affects the quality of life of patients. The risk of post-ICU syndrome is associated with factors such as advanced age, delirium, prolonged sedation and mechanical ventilation.

The main objective of this study is to assess the temporal evolution of post-ICU syndrome in patients who required mechanical ventilation for more than 48 hours.

Specific objectives:

* To establish the incidence of PICUS in patients admitted to the ICU for respiratory failure between January 2021 and December 2024.
* To identify the risk factors associated with the development of post-ICU syndrome in these patients, considering both clinical and sociodemographic factors.
* To evaluate the impact of post-ICU syndrome on the quality of life of patients over time, studying the physical, cognitive and psychological consequences of the syndrome.
* To explore the impact on their families, analyzing the emotional impact and the quality of life of caregivers.

This is a cross-sectional study, in which no experimental intervention will be carried out on the patients.

The study population will be patients hospitalized in the Intensive Care Unit between January 2021 and December 2024 undergoing mechanical ventilation for more than 48 hours. Deceased persons, those who did not give their consent, and minors will not be included. The final sample size is expected to be representative for the purposes of the study.

Data collection will be carried out through interviews in 2025, which will allow obtaining detailed information on the current situation of these patients about the presence of symptoms as a consequence of their stay in the ICU more than two years ago.
