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.

Abstract Rationale: ICU nurses can experience high levels of burnout and job dissatisfaction due to stressors associated with high-stakes patient care, uncertain outcomes, and constant exposure to death. Witnessing patient recovery and/or disability status in the weeks or months after hospital discharge through reconnection with survivors of critical illness and their families may offer emotional and professional benefits to ICU nurses. However, the impact of connecting with patients’ post-ICU outcomes on nursing clinical practice and job satisfaction has not been well explored. This study aimed to investigate pragmatic perspectives from ICU nurses related to their insights on long-term patient outcomes after critical illness with a goal of identifying key mechanisms that may be associated with impacts on clinical practice and job satisfaction. Methods: A web-based investigator-designed survey was distributed to ICU nurses with endorsement from the American Association of Critical-Care Nurses for completion via their website and annual conference. Survey items included quantitative and open-ended prompts to examine the impact of reconnecting with ICU survivors on clinical practice and job satisfaction. Thematic analysis was performed on free-text responses. Results: Fifty-four ICU nurses (76% female) participated in the survey (June 2023-May 2024), with a median age of 41 years and a median of 7 years of critical care experience. Among them, 89% reported that reconnecting with survivors positively impacted their job satisfaction, and 78% felt that reconnecting influenced their clinical practice. Thematic analysis revealed three themes: Empathy and Human Connection – Nurses felt validated and fulfilled knowing their care positively impacted patients’ lives, reinforcing the meaning of their work. These interactions fostered greater empathy, reminding nurses of the real-life impact of their care.Validation of Effort and Accomplishment – Nurses reported a stronger sense of accomplishment seeing the positive outcomes of their work. Reconnecting with survivors reaffirmed the importance of their roles, strengthening nurses’ sense of purpose and commitment.Positive Emotional Impact and Job Satisfaction – Interactions with survivors provided emotional uplift, enhancing job satisfaction and reminding nurses of the rewarding aspects of their roles. Gratitude and progress from survivors motivated nurses, helping them manage the emotional challenges of ICU work. Conclusion: Reconnecting with ICU survivors and their families may have positive impacts on job satisfaction and clinical practice by providing emotional rewards, reinforcing nurses’ professional purpose, and validating their contributions to patient recovery. Embedding structured, low-cost re-engagement activities with critical illness survivors could offer valuable benefits to the ICU nurse workforce.

AbstractBACKGROUNDDelirium, a common syndrome with heterogeneous etiologies and clinical presentations, is associated with poor long‐term outcomes. Recording and analyzing all delirium equally could be hindering the field's understanding of pathophysiology and identification of targeted treatments. Current delirium subtyping methods reflect clinically evident features but likely do not account for underlying biology.METHODSThe Delirium Subtyping Initiative (DSI) held three sessions with an international panel of 25 experts.RESULTSMeeting participants suggest further characterization of delirium features to complement the existing Diagnostic and Statistical Manual of Mental Disorders Fifth Edition Text Revision diagnostic criteria. These should span the range of delirium‐spectrum syndromes and be measured consistently across studies. Clinical features should be recorded in conjunction with biospecimen collection, where feasible, in a standardized way, to determine temporal associations of biology coincident with clinical fluctuations.DISCUSSIONThe DSI made recommendations spanning the breadth of delirium research including clinical features, study planning, data collection, and data analysis for characterization of candidate delirium subtypes.Highlights Delirium features must be clearly defined, standardized, and operationalized. Large datasets incorporating both clinical and biomarker variables should be analyzed together. Delirium screening should incorporate communication and reasoning.
