Abstract Rationale: Critical illness survivors often experience anxiety, depression, and post-traumatic stress disorder (PTSD) due to traumatic experiences, sedation, and delirium. Early interventions of psychological support may help mitigate mental health deficits post-ICU. Memory of the ICU stay may play a key role in addressing trauma and facilitating therapeutic engagement. Therefore, we sought to determine the relationship between ICU memory recollection, in-ICU delirium, and mental health outcomes at 1-month follow-up in a critical illness recovery center. Methods: We analyzed data collected at 1-month follow-up in a critical illness recovery center seeing adults who had ICU stays of >4 days with sepsis, respiratory failure, and/or delirium. Patients were asked, “Do you remember your experience in the ICU, and if so, can you describe your most impactful memories?” and we qualitatively coded responses for A) presence/absence of memories and B) type of memories described. We analyzed unadjusted associations between demographic, clinical, and mental health measures (anxiety, depression, and PTSD) and memory recollection using chi-square and Wilcoxon rank-sum tests. Results: Among 196 patients seen at 1-month follow-up, 96 (49%) reported memories of their ICU stay. Of these, 44 (46%) described support they received in the ICU (e.g., feeling “safe and watched” by ICU staff, spouse at bedside), 36 (38%) recalled delusions and/or hallucinations (e.g., being kidnapped), 35 (37%) remembered specific treatments (e.g., cardioversion), and 33 (34%) described symptoms (e.g., pain, constipation). Baseline characteristics and critical illness features are shown in the Table. Patients who reported no memories of their ICU stay were more frequently admitted with neurological diagnoses, whereas those who reported memories were more often admitted with trauma or burns (p<0.001). Those without memories had more delirium days than those reporting memories (p=0.02). Although PTSD and anxiety symptoms at 1-month follow-up were not associated with memories, patients who remembered their ICU stay had fewer depression symptoms (p=0.04). Conclusions: One month after their critical illness, half of survivors recalled their ICU experience, with memories ranging from supportive interactions to distressing experiences. In unadjusted analyses, memory recollection was associated with fewer depressive symptoms during follow-up, but a larger study is needed to determine whether this association persists after adjusting for potential confounders. Memories of the ICU may provide a therapeutic foundation for interventions targeting depression after critical illness, such as exposure therapy or ICU diaries, which may improve mental health outcomes in critical illness survivors.

OBJECTIVES: To engage critical care end-users (survivors and caregivers) to describe their emotions and experiences across their recovery trajectory, and elicit their ideas and solutions for health service improvements to improve the ICU recovery experience. DESIGN: End-user engagement as part of a qualitative design using the Framework Analysis method. SETTING: The Society of Critical Care Medicine’s THRIVE international collaborative sites (follow-up clinics and peer support groups). SUBJECTS: Patients and caregivers following critical illness and identified through the collaboratives. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Eighty-six interviews were conducted. The following themes were identified: 1) Emotions and experiences of patients—“Loss of former self; Experiences of disability and adaptation”; 2) Emotions and experiences of caregivers—“Emotional impacts, adopting new roles, and caregiver burden; Influence of gender roles; Adaptation, adjustment, recalibration”; and 3) Patient and caregiver-generated solutions to improve recovery across the arc of care—“Family-targeted education; Expectation management; Rehabilitation for patients and caregivers; Peer support groups; Reconnecting with ICU post-discharge; Access to community-based supports post-discharge; Psychological support; Education of issues of ICU survivorship for health professionals; Support across recovery trajectory.” Themes were mapped to a previously published recovery framework (Timing It Right) that captures patient and caregiver experiences and their support needs across the phases of care from the event/diagnosis to adaptation post-discharge home. CONCLUSIONS: Patients and caregivers reported a range of emotions and experiences across the recovery trajectory from ICU to home. Through end-user engagement strategies many potential solutions were identified that could be implemented by health services and tested to support the delivery of higher-quality care for ICU survivors and their caregivers that extend from tertiary to primary care settings.

Objectives Social determinants of health (SDoH) contribute to health outcomes. We identified SDoH that were modified by critical illness, and the effect of such modifications on recovery from critical illness. Design In-depth semistructured interviews following hospital discharge. Interview transcripts were mapped against a pre-existing social policy framework: money and work; skills and education; housing, transport and neighbourhoods; and family, friends and social connections. Setting 14 hospital sites in the USA, UK and Australia. Participants Patients and caregivers, who had been admitted to critical care from three continents. Results 86 interviews were analysed (66 patients and 20 caregivers). SDoH, both financial and non-financial in nature, could be negatively influenced by exposure to critical illness, with a direct impact on health-related outcomes at an individual level. Financial modifications included changes to employment status due to critical illness-related disability, alongside changes to income and insurance status. Negative health impacts included the inability to access essential healthcare and an increase in mental health problems. Conclusions Critical illness appears to modify SDoH for survivors and their family members, potentially impacting recovery and health. Our findings suggest that increased attention to issues such as one’s social network, economic security and access to healthcare is required following discharge from critical care.

OBJECTIVES: Investigate the challenges experienced by survivors of critical illness and their caregivers across the transitions of care from intensive care to community, and the potential problem-solving strategies used to navigate these challenges. DESIGN: Qualitative design—data generation via interviews and data analysis via the framework analysis method. SETTING: Patients and caregivers from three continents, identified through the Society of Critical Care Medicine’s THRIVE international collaborative sites (follow-up clinics and peer support groups). SUBJECTS: Patients and caregivers following critical illness. INTERVENTIONS: Nil MEASUREMENTS AND MAIN RESULTS: From 86 interviews (66 patients, 20 caregivers), we identified the following major themes: 1) Challenges for patients—interacting with the health system and gaps in care; managing others’ expectations of illness and recovery. 2) Challenges for caregivers—health system shortfalls and inadequate communication; lack of support for caregivers. 3) Patient and caregiver-driven problem solving across the transitions of care—personal attributes, resources, and initiative; receiving support and helping others; and acceptance. CONCLUSIONS: Survivors and caregivers experienced a range of challenges across the transitions of care. There were distinct and contrasting themes related to the caregiver experience. Survivors and caregivers used comparable problem-solving strategies to navigate the challenges encountered across the transitions of care.

Background After critical illness, patients are often left with impairments in physical, social, emotional, and cognitive functioning. Peer support interventions have been implemented internationally to ameliorate these issues. Objective To explore what patients believed to be the key mechanisms of effectiveness of peer support programs implemented during critical care recovery. Methods In a secondary analysis of an international qualitative data set, 66 telephone interviews with patients were undertaken across 14 sites in Australia, the United Kingdom, and the United States to understand the effect of peer support during recovery from critical illness. Prevalent themes were documented with framework analysis. Results Most patients who had been involved in peer support programs reported benefit. Patients described 3 primary mechanisms: (1) sharing experiences, (2) care debriefing, and (3) altruism. Conclusion Peer support is a relatively simple intervention that could be implemented to support patients during recovery from critical illness. However, more research is required into how these programs can be implemented in a safe and sustainable way in clinical practice.

Background: After critical illness, new or worsening impairments in physical, cognitive, and/or mental health function are common among patients who have survived. Who should be screened for long-term impairments, what tools to use, and when remain unclear. Objectives: Provide pragmatic recommendations to clinicians caring for adult survivors of critical illness related to screening for postdischarge impairments. Participants: Thirty-one international experts in risk-stratification and assessment of survivors of critical illness, including practitioners involved in the Society of Critical Care Medicine’s Thrive Post-ICU Collaboratives, survivors of critical illness, and clinical researchers. Design: Society of Critical Care Medicine consensus conference on post-intensive care syndrome prediction and assessment, held in Dallas, in May 2019. A systematic search of PubMed and the Cochrane Library was conducted in 2018 and updated in 2019 to complete an original systematic review and to identify pre-existing systematic reviews. Meeting Outcomes: We concluded that existing tools are insufficient to reliably predict post-intensive care syndrome. We identified factors before (e.g., frailty, preexisting functional impairments), during (e.g., duration of delirium, sepsis, acute respiratory distress syndrome), and after (e.g., early symptoms of anxiety, depression, or post-traumatic stress disorder) critical illness that can be used to identify patients at high-risk for cognitive, mental health, and physical impairments after critical illness in whom screening is recommended. We recommend serial assessments, beginning within 2–4 weeks of hospital discharge, using the following screening tools: Montreal Cognitive Assessment test; Hospital Anxiety and Depression Scale; Impact of Event Scale-Revised (post-traumatic stress disorder); 6-minute walk; and/or the EuroQol-5D-5L, a health-related quality of life measure (physical function). Conclusions: Beginning with an assessment of a patient’s pre-ICU functional abilities at ICU admission, clinicians have a care coordination strategy to identify and manage impairments across the continuum. As hospital discharge approaches, clinicians should use brief, standardized assessments and compare these results to patient’s pre-ICU functional abilities (“functional reconciliation”). We recommend serial assessments for post-intensive care syndrome-related problems continue within 2–4 weeks of hospital discharge, be prioritized among high-risk patients, using the identified screening tools to prompt referrals for services and/or more detailed assessments.

Objectives: To understand from the perspective of patients who did, and did not attend ICU recovery programs, what were the most important components of successful programs and how should they be organized. Design: International, qualitative study. Setting: Fourteen hospitals in the United States, United Kingdom, and Australia. Patients: We conducted 66 semi-structured interviews with a diverse group of patients, 52 of whom had used an ICU recovery program and 14 whom had not. Interventions: None. Measurements and Main Results: Using content analysis, prevalent themes were documented to understand what improved their outcomes. Contrasting quotes from patients who had not received certain aspects of care were used to identify perceived differential effectiveness. Successful ICU recovery programs had five key components: 1) Continuity of care; 2) Improving symptom status; 3) Normalization and expectation management; 4) Internal and external validation of progress; and 5) Reducing feelings of guilt and helplessness. The delivery of care which achieved these goals was facilitated by early involvement (even before hospital discharge), direct involvement of ICU staff, and a focus on integration across traditional disease, symptom, and social welfare needs. Conclusions: In this multicenter study, conducted across three continents, patients identified specific and reproducible modes of benefit derived from ICU recovery programs, which could be the target of future intervention refinement.
