Study summary

Survivors of critical illness frequently develop persistent cognitive and emotional impairments, known as post-intensive care syndrome (PICS), which substantially impact quality of life and long-term recovery. While prior research has mainly focused on identifying risk factors, the mechanisms underlying resilience to these sequelae remain poorly understood. Emerging evidence suggests that biological factors, including inflammatory responses and genetic vulnerability, together with cognitive reserve, may play a key role in shaping recovery trajectories.

The aim of this multicenter, prospective observational study is to investigate how cognitive reserve, inflammatory phenotype, and genetic profiles interact to influence cognitive and emotional recovery after critical illness. Adult patients will be recruited at Intensive Care Unit (ICU) admission across two centers in Spain. Clinical and sociodemographic data will be collected during the ICU stay, and biological samples obtained early after admission will undergo transcriptomic and genetic analyses. Cognitive and emotional outcomes will be assessed at hospital discharge and at 3 and 12 months post-discharge using standardised neuropsychological and telemedicine-based evaluations.

By integrating clinical, biological, and cognitive data, this study seeks to identify recovery phenotypes and resilience mechanisms in PICS. The results may contribute to improved risk stratification, inform personalized interventions, and support the development of future strategies aimed at reducing the long-term burden of critical illness.

Study population

Critically ill patients admitted to the medical / post-surgical ICU of the Parc Tauli Hospital (Sabadell, Spain), and to the Hospital Universitario Central de Asturias.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Exclusion criteria

Exclusion Criteria:

  • Non-authorisation by the patient and/or relatives for inclusion in the study
  • Patients admitted to a neurocritical ICU
  • History of severe neurological disease (including dementia or focal brain injury with functional and cognitive impairment) prior to ICU admission
  • History of severe psychiatric disorders (schizophrenia, bipolar disorder, major depressive disorder)
  • Intellectual disability (IQ \<80) or other neurodevelopmental disorders, such as autism spectrum disorder
  • Patients who develop secondary complications (e.g., infections, stroke, traumatic brain injury, or other non-transient acquired brain injury) after ICU discharge that may compromise the results of emotional and neuropsychological evaluations during the recovery phase
  • Moderate to severe cognitive impairment (Short-IQCODE >57) preventing independent participation in telemedicine or face-to-face follow-up
  • Readmission to the ICU within 12 months after ICU discharge
  • Language barrier (non-Spanish- and/or non-Catalan-speaking patients)
  • Patients with a \<1 year or not eligible for active treatment measures
Terms in these criteria, in plain language(2)

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.

Informed consent

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
