Post Intensive Care Unit Syndrome

The overarching goal of the proposed study is to determine the trajectories of physical recovery and cellular markers involved with the underlying failure to recover muscle after critical illness, while exploring which characteristics are associated with sustained physical disability. This proposal will examine muscle pathophysiology carefully aligned with physical function outcomes in order to longitudinally assess the recovery, or failed recovery, of muscle function in participants after critical illness: 1. to examine the recovery of muscle and physical function in ICU survivors through longitudinal assessments 2. to investigate the underlying cellular markers and mechanisms of muscle recovery in ICU survivors 3. to determine which cellular markers contribute to physical disability in ICU survivors up to 1 year after hospital admission

The purpose of this study is to measure the feasibility, acceptability of virtual reality (VR) brain games and estimate their effect on memory, attention, and mood for ICU survivors. The VR program will be used at home through a headset and hand controls.

The goal of this clinical trial is to learn if daily oral supplementation with pasteurized Akkermansia muciniphila (PAM), an EFSA-approved food supplement, can support recovery in adults who have recently been treated in the ICU for sepsis. The main questions it aims to answer are: * Is PAM safe to take for 56 days after ICU discharge? * Does PAM increase the abundance of beneficial butyrate-producing bacteria in the gut? Researchers will compare PAM to a placebo (a capsule that looks the same but has no active ingredient) to see if PAM improves gut microbiota and immune recovery. Participants will: * Take PAM or placebo capsules once daily for 56 days * Provide stool and blood samples at baseline, day 28, and day 56 * Receive a follow-up phone call about their health 1 year after starting the study

BACKGROUND: ICU survivors may experience serious psychological, physical and cognitive impairments following ICU admission, collectively termed Post Intensive Care Syndrome (PICS). Persistent pain is an underrecognized component of PICS. Previous research has shown that persistent pain is a profound clinical challenge in ICU survivors, however, research demonstrates conflicting results. Furthermore, no studies have examined the prevalence of persistent pain in ICU survivors in a contemporary Danish ICU setting. OBJECTIVES: We aim to examine the clinical trajectory, risk factors, and pathophysiology of persistent pain in ICU survivors in Denmark. DESIGN AND SAMPLE SIZE: The study is designed as a multicenter, prospective, inception cohort study with clinical follow-up. Based on the pre-study sample size calculation, 800 patients will be included. Patients will be contacted by telephone 90 days and 180 days after ICU discharge, and a series of questionnaires regarding pain, sleep quality, affective state and quality of life will be completed. A subgroup of patients will undergo a detailed clinical examination including quantitative sensory testing between 180-365 days after ICU discharge. POPULATION: Patients will be recruited from 4 Danish ICU departments. Inclusion criteria include adult patients (18 years of age), acute admission to the ICU, and an ICU admission of a minimum of 48 hours. OUTCOMES: The primary outcome is the prevalence of pain assessed by the Brief Pain Inventory (BPI) at 90 and 180 days after ICU discharge. Secondary outcomes include additional detailed descriptions of pain and daily activity, sleep quality, affective state, quality of life, treatment- and patient-related risk factors, and biomarkers associated with development of persistent pain. Substudies: \- QST substudy: 80 participants (40 with pain and 40 without pain) recruited from the main cohort will undergo Quantative Somatosensory Testing (QST). The objectives are first, to delineate somatosensory profiles of ICU survivors with and without pain, and second, to examine the presence of neuropathic pain in ICU survivors.

Background: In the intensive care unit (ICU), delirium in patients and long-term mental health challenges in both patients and their family members are highly prevalent. To address these issues, patient- and family-centered care has been recommended to alleviate the burdens associated with critical illness and ICU admission. We have developed the patient- and FAMily-centered care in the adult ICU intervention (FAM-ICU intervention). This multi-component intervention comprises several concrete and manageable components and operationalizing patient- and family-centered care principles in clinical practice. In this protocol, we describe a study aiming to evaluate the feasibility and acceptability of the FAM-ICU intervention in the adult ICU setting, including the feasibility of collecting relevant patient- and family-member outcome data.

We plan to recruit 30 adult ICU patients and their close family members at Herlev University Hospital in Denmark. The pre-group (n = 15) will receive usual care and the post-group (n = 15) will receive the FAM-ICU intervention. The FAM-ICU intervention involves interdisciplinary training of the ICU team and a systematic approach to information sharing and consultations with the patients and their family. Feasibility outcomes will include recruitment and retention rates, intervention fidelity, and the feasibility of participant outcome data collection. Acceptability will be assessed through questionnaires and interviews with clinicians, patients, and family members. Data collection is scheduled to begin in January 2025. Discussion: This study will assess the feasibility and acceptability when implementing the FAM-ICU intervention and the feasibility of conducting a main trial to investigate its effectiveness on delirium in patients and the mental health of patients and family members. The data from the feasibility study will be used to guide sample size calculations, trial design, and final data collection methods for a subsequent stepped-wedge randomized controlled trial.
