Higher levels of circulating desphospho-uncarboxylated matrix Gla protein over time are associated with worse survival: the prospective Maastricht Intensive Care COVID cohort

BackgroundExtra-hepatic vitamin K-status, measured by dephosphorylated uncarboxylated matrix Gla protein (dp-ucMGP), maintains vascular health, with high levels reflecting poor vitamin K status. The occurrence of extra-hepatic vitamin K deficiency throughout the disease of COVID-19 and possible associations with pulmonary embolism (PE), and mortality in intensive care unit (ICU) patients has not been studied. The aim of this study was to investigated the association between dp-ucMGP, at endotracheal intubation (ETI) and both ICU and six months mortality. Furthermore, we studied the associations between serially measured dp-ucMGP and both PE and mortality.MethodsWe included 112 ICU patients with confirmed COVID-19. Over the course of 4 weeks after ETI, dp-ucMGP was measured serially. All patients underwent computed tomography pulmonary angiography (CTPA) to rule out PE. Results were adjusted for patient characteristics, disease severity scores, inflammation, renal function, history of coumarin use, and coronary artery calcification (CAC) scores.ResultsPer 100 pmol/L dp-ucMGP, at ETI, the odds ratio (OR) was 1.056 (95% CI: 0.977 to 1.141, p = 0.172) for ICU mortality and 1.059 (95% CI: 0.976 to 1.059, p = 0.170) for six months mortality. After adjustments for age, gender, and APACHE II score, the mean difference in plasma dp-ucMGP over time of ICU admission was 167 pmol/L (95% CI: 4 to 332, p = 0.047). After additional adjustments for c-reactive protein, creatinine, and history of coumarin use, the difference was 199 pmol/L (95% CI: 50 to 346, p = 0.010). After additional adjustment for CAC score the difference was 213 pmol/L (95% CI: 3 to 422, p = 0.051) higher in ICU non-survivors compared to the ICU survivors. The regression slope, indicating changes over time, did not differ. Moreover, dp-ucMGP was not associated with PE.ConclusionICU mortality in COVID-19 patients was associated with higher dp-ucMGP levels over 4 weeks, independent of age, gender, and APACHE II score, and not explained by inflammation, renal function, history of coumarin use, and CAC score. No association with PE was observed. At ETI, higher levels of dp-ucMGP were associated with higher OR for both ICU and six month mortality in crude and adjusted modes, although not statistically significantly.

Prediction of Long-Term Physical, Mental, and Cognitive Problems Following Critical Illness: Development and External Validation of the PROSPECT Prediction Model.

ICU survivors often suffer from long-lasting physical, mental, and cognitive health problems after hospital discharge. As several interventions that treat or prevent these problems already start during ICU stay, patients at high risk should be identified early. This study aimed to develop a model for early prediction of post-ICU health problems within 48 hours after ICU admission. Prospective cohort study in seven Dutch ICUs. ICU patients older than 16 years and admitted for greater than or equal to 12 hours between July 2016 and March 2020. None. Outcomes were physical problems (fatigue or ≥ 3 new physical symptoms), mental problems (anxiety, depression, or post-traumatic stress disorder), and cognitive impairment. Patient record data and questionnaire data were collected at ICU admission, and after 3 and 12 months, of 2,476 patients. Several models predicting physical, mental, or cognitive problems and a composite score at 3 and 12 months were developed using variables collected within 48 hours after ICU admission. Based on performance and clinical feasibility, a model, PROSPECT, predicting post-ICU health problems at 3 months was chosen, including the predictors of chronic obstructive pulmonary disease, admission type, expected length of ICU stay greater than or equal to 2 days, and preadmission anxiety and fatigue. Internal validation using bootstrapping on data of the largest hospital ( n = 1,244) yielded a C -statistic of 0.73 (95% CI, 0.70-0.76). External validation was performed on data ( n = 864) from the other six hospitals with a C -statistic of 0.77 (95% CI, 0.73-0.80). The developed and externally validated PROSPECT model can be used within 48 hours after ICU admission for identifying patients with an increased risk of post-ICU problems 3 months after ICU admission. Timely preventive interventions starting during ICU admission and follow-up care can prevent or mitigate post-ICU problems in these high-risk patients.

Effectiveness of a novel bubble CPAP system for neonatal respiratory support at a referral hospital in the Philippines.

To examine the impact of introducing and implementing the Vayu bubble continuous positive airway pressure (bCPAP) system on neonatal survival and neonatal respiratory outcomes in a neonatal intensive care unit (NICU) in the Philippines. We compared clinical outcomes of 1,024 neonates before to 979 neonates after introduction of Vayu bCPAP systems into a NICU. The primary outcome was survival to discharge. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were calculated. Analyses were undertaken separately for the entire NICU population and for neonates who received any form of respiratory support. The introduction of the Vayu bCPAP system was associated with (1) significant reductions in intubation (aOR: 0.75; 95% CI: 0.58-0.96) and in the use of nasal intermittent positive-pressure ventilation (NIPPV) (aOR: 0.69; 95% CI: 0.50-0.96) among the entire NICU population and (2) a significant increase in survival to discharge (aOR: 1.53; 95% CI: 1.09-2.17) and significant reductions in intubation (aOR: 0.52; 95% CI: 0.38-0.71), surfactant administration (aOR: 0.60; 95% CI: 0.40-0.89), NIPPV use (aOR: 0.52; 95% CI: 0.36-0.76), and a composite neonatal adverse outcome (aOR: 0.60; 95% CI: 0.42-0.84) among neonates who received any form of respiratory support. The use of the Vayu bCPAP system in a NICU in the Philippines resulted in significant improvement in neonatal respiratory outcomes.

Psychological symptoms and health-related quality of life in intubated and non-intubated intensive care survivors: A multicentre, prospective observational cohort study

ObjectiveTo compare long-term psychological symptoms and health-related quality of life (HRQOL) in intubated versus non-intubated ICU survivors. DesignProspective, multicentre observational cohort study. SettingFour tertiary medical-surgical ICUs in Australia. ParticipantsIntubated and non-intubated adult ICU survivors. Main outcome measuresPrimary outcomes: clinically significant psychological symptoms at 3- and 12-month follow-up using Post-Traumatic Stress Syndrome-14 for post-traumatic stress disorder; Depression, Anxiety Stress Scales-21 for depression, anxiety, and stress. Secondary outcomes: HRQOL, using EuroQol-5D-5L questionnaire. ResultsOf the 133 ICU survivors, 54/116 (47 %) had at least one clinically significant psychological symptom (i.e., post-traumatic stress disorder, anxiety, depression, stress) at follow-up. Clinically significant scores for psychological symptoms were observed in 26 (39 %) versus 16 (32 %) at 3-months [odds ratio 1.4, 95 % confidence interval (0.66–3.13), p = 0.38]; 23 (37 %) versus 10 (31 %) at 12-months [odds ratio 1.3, 95 % confidence interval (0.53–3.31), p = 0.57] of intubated versus non-intubated survivors, respectively. Usual activities and mobility were the most commonly affected HRQOL dimension, with >30 % at 3 versus months and >20 % at 12-months of overall survivors reporting ≥ moderate problems. There was no difference between the groups in any of the EQ5D dimensions. ConclusionsNearly one-in-two (47 %) of the intubated and non-intubated ICU survivors reported clinically significant psychological symptoms at 3 and 12-month follow-ups. Overall, more than 30 % at 3-months and over 20 % at 12-months of the survivors in both groups had moderate or worse problems with their usual activities and mobility. The presence of psychological symptoms and HRQOL impairments was similar between the groups.

Effects of education, income and employment on ICU and post-ICU survival - A nationwide Swedish cohort study of individual-level data with 1-year follow up

PurposeThe aim of this study was to examine relationships between education, income, and employment (socioeconomic status, SES) and intensive care unit (ICU) survival and survival 1 year after discharge from ICU (Post-ICU survival). MethodsIndividual data from ICU patients were linked to register data of education level, disposable income, employment status, civil status, foreign background, comorbidities, and vital status. Associations between SES, ICU survival and 1-year post-ICU survival was analysed using Cox's regression. ResultsWe included 58,279 adults (59% men, median length of stay in ICU 4.0 days, median SAPS3 score 61). Survival rates at discharge from ICU and one year after discharge were 88% and 63%, respectively. Risk of ICU death (Hazard ratios, HR) was significantly higher in unemployed and retired compared to patients who worked prior to admission (1.20; 95% CI: 1.10–1.30 and 1.15; (1.07–1.24), respectively. There was no consistent association between education, income and ICU death. Risk of post-ICU death decreased with greater income and was roughly 16% lower in the highest compared to lowest income quintile (HR 0.84; 0.79–0.88). Higher education levels appeared to be associated with reduced risk of death during the first year after ICU discharge. ConclusionsSignificant relationships between low SES in the critically ill and increased risk of death indicate that it is important to identify and support patients with low SES to improve survival after intensive care. Studies of survival after critical illness need to account for participants SES.

Hyperglycemia and glucose variability are associated with worse survival in mechanically ventilated COVID-19 patients: the prospective Maastricht Intensive Care Covid Cohort

BackgroundData on hyperglycemia and glucose variability in relation to diabetes mellitus, either known or unknown in ICU-setting in COVID-19, are scarce. We prospectively studied daily glucose variables and mortality in strata of diabetes mellitus and glycosylated hemoglobin among mechanically ventilated COVID-19 patients.MethodsWe used linear-mixed effect models in mechanically ventilated COVID-19 patients to investigate mean and maximum difference in glucose concentration per day over time. We compared ICU survivors and non-survivors and tested for effect-modification by pandemic wave 1 and 2, diabetes mellitus, and admission HbA1c.ResultsAmong 232 mechanically ventilated COVID-19 patients, 21.1% had known diabetes mellitus, whereas 16.9% in wave 2 had unknown diabetes mellitus. Non-survivors had higher mean glucose concentrations (ß 0.62 mmol/l; 95%CI 0.20–1.06; ß 11.2 mg/dl; 95% CI 3.6–19.1; P = 0.004) and higher maximum differences in glucose concentrations per day (ß 0.85 mmol/l; 95%CI 0.37–1.33; ß 15.3; 95%CI 6.7–23.9; P = 0.001). Effect modification by wave, history of diabetes mellitus and admission HbA1c in associations between glucose and survival was not present. Effect of higher mean glucose concentrations was modified by pandemic wave (wave 1 (ß 0.74; 95% CI 0.24–1.23 mmol/l) ; (ß 13.3; 95%CI 4.3–22.1 mg/dl)) vs. (wave 2 (ß 0.37 (95%CI 0.25–0.98) mmol/l) (ß 6.7 (95% ci 4.5–17.6) mg/dl)).ConclusionsHyperglycemia and glucose variability are associated with mortality in mechanically ventilated COVID-19 patients irrespective of the presence of diabetes mellitus.

Functional independence, frailty and perceived quality of life in patients who developed delirium during ICU stay: a prospective cohort study

BackgroundSurvivors of critical illness are frequently left with a long-lasting disability. We hypothesised that patients who developed delirium during ICU stay, compared with patients who did not, would have worse health-related quality of life following a critical illness.MethodsProspective longitudinal observational and analytical study assessing functional independence, frailty and perceived quality of life measured with the Barthel Index, the Clinical Frailty Scale, and the SF-36, comparing patients who developed delirium during ICU stay and patients who did not. The questionnaires were used at different times during the follow-up (upon ICU admission, at ICU discharge, at hospital discharge and 2 years after hospital discharge).ResultsIn a cohort of 1462 patients, we matched 93 patients who developed delirium (delirium group) with 93 patients who did not develop delirium (no-delirium group). Of 156 completed questionnaires (84.7%), we observed that (a) in each of the two groups of patients, the scores related to functional independence (Barthel Index) and frailty (Clinical Frailty Scale) tended to improve over time (p < 0.001), being consistently less favourable in the delirium group compared to the no-delirium group (p < 0.001); (b) the patients who developed delirium also presented lower scores on the SF-36 scale, these differences being statistically significant, and therefore evidencing a worse quality of life, with impact on both the psychological and social spheres (p < 0.001).ConclusionsPatients who developed delirium had significantly lower scores 2 years after hospital discharge on the three used questionnaires, displaying a clear negative impact on the physical, psychological, and social dimensions. The study's results reinforce the need to support and strengthen the care of ICU survivors.

Plasma ADRD Biomarkers are Altered in COVID‐19 ICU Survivors

AbstractBackgroundLong Covid, which features cognitive symptoms in some people, affects an estimated 23.3 million Americans. Older adult survivors of COVID‐19‐associated critical illness are more likely to experience the cognitive symptoms of Long Covid, including deficits in attention, memory, and executive functioning. We sought to evaluate Alzheimer’s disease and related dementia (ADRD) plasma biomarkers in pilot study of older ICU survivors of COVID‐19‐related critical illness and non‐COVID critical illness.Method17 ICU survivors (13 COVID‐19, 4 non‐COVID) underwent clinical and cognitive testing, a blood sample, and a structural MRI approximately 2 months after ICU discharge. Plasma from the blood sample was extracted, and SIMOA assays were used to measure Aβ42, Aβ40, glial fibrillar acidic protein (GFAP), neurofilament light chain (NfL), and phosphorylated tau (pTau181). Structural MRI scans were processed using Freesurfer version 6 to measure brain atrophy (mean global cortical thickness). Plasma analyte values over three standard deviations outside the mean of the whole group were excluded (1 NfL and 1 pTau). Two‐sample t‐tests were used to compare plasma analytes between ICU groups. Pearson or Spearman correlation models were used to evaluate the relationship of target analytes with brain volumes. Covariates were tested but did not change the results.ResultSignificantly lower Aβ42/40 ratio and Aβ42 levels were observed in COVID‐19 ICU survivors relative to non‐COVID ICU survivors (Figure 1). Across all participants Aβ42/40 ratio was not associated with mean global cortical thickness, while NfL and GFAP levels were negatively associated with cortical thickness (Figure 2). However, when limited to only the COVID‐19 ICU survivors, a more ADRD‐like pattern was observed, with a trend for a positive association of Aβ42/40 ratio with cortical thickness and negative association of GFAP and NfL with cortical thickness (Figure 3).ConclusionCognitive impairment in COVID‐19 critical illness may be related to ADRD pathophysiology. Future studies in larger samples of COVID‐19 ICU survivors, as well as those with Long Covid symptoms with a history of mild to moderate COVID‐19 infection are needed to better understand these relationships.

Impact of acute kidney injury on major adverse cardiovascular events in intensive care survivors

BackgroundAcute kidney injury commonly occurs in patients admitted to ICU. After acute kidney injury, kidney function may not completely recover leading to increased risk of future cardiovascular events. We sought to ascertain the rates of cardiovascular events in ICU survivors and if these rates were affected by the presence of acute kidney injury whilst in ICU. MethodsThis retrospective observational cohort study utilised routinely collected data to identify patients who had survived an admission to one of two ICUs between July 2015 and June 2018. Baseline serum creatinine and subsequent values were used to identify acute kidney injury. Major adverse cardiovascular events described were myocardial injury, coronary artery intervention, or radiological evidence of stroke. ResultsOf the 3994 ICU survivors, major adverse cardiovascular events were identified in 385 patients (9.6%; 95% confidence interval [CI] 8.8–10.6%). Presence of acute kidney injury whilst in ICU was significantly associated with future major adverse cardiovascular events (hazard ratio=1.38; 95% CI 1.12–1.70; P-value=0.003) and future biochemical myocardial injury (hazard ratio=1.48; 95% CI 1.16–1.89; P-value=0.001). Acute kidney injury did not have a statistically significant association with future coronary artery interventions or future cerebrovascular events. ConclusionsOne in 10 ICU survivors experiences a major adverse cardiovascular event after discharge. Acute kidney injury whilst in ICU was associated with an increased risk of major adverse cardiovascular events and specifically myocardial injury. Further research is warranted on whether ICU survivors with acute kidney injury merit enhanced strategies for cardiovascular protection.

Assessment of health-related quality of life and its determinants among COVID-19 intensive care unit survivors.

Health-related quality of life (HRQoL) is a multidimensional concept encompassing the physical, functional, emotional, and social/family well-being of an individual. Recent reports suggest that Covid-19 may lead to poorer HRQoL of the patients infected both in the short and long term. The present study aimed to assess the health-related quality of life and their determinants among COVID-19 intensive care unit (ICU) survivors. In the study, 107 COVID-19 (RTPCR positive) patients admitted to the (ICU) of a tertiary care centre from August 2021-January 2022 were taken from the hospital records. Line listing of all the patients was done, and the study population was selected using the lottery method under a simple random sampling method. The study population was contacted by telephone and requested their willingness to participate in the study. EQ-5D-5L was used to assess quality of life, which is a standard instrument to assess HRQoL (developed by the EuroQol group in 2011). The EQ-5D-5L essentially consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ-VAS). Data entry was done using Microsoft excel 2019 version and data analysis using MedCalc version 20.015. The mean EQ-5D-5L utility score was 0.51 ± 0.43. The mean EQ-VAS score was 68.97 ± 22.27. A significant association between co-morbidities and EQ-5D-5L utility score where those with co-morbidities had a lesser EQ-5D-5L score compared to those without co-morbidities. The mean duration of ICU stay in days was 12.29 ± 12.17. A significant negative correlation between the duration of ICU stay and EQ-5D-5L. (r = -0.26, P = 0.0006*). COVID-19 patients with comorbidities had a significantly poor quality of life. These findings may help healthcare professionals and decision-makers to better understand the consequences of COVID-19 on the HRQoL.

Protein and energy intake in intensive care unit survivors during the first year of recovery: A descriptive cohort study.

Many intensive care unit (ICU) survivors suffer long-term health issues that affect their quality of life. Nutrition inadequacy can limit their rehabilitation potential. This study investigates nutrition intake and support during ICU admission and recovery. In this prospective cohort study, 81 adult ICU patients with stays ≥48 h were included. Data on dietary intake, feeding strategies, baseline and ICU characteristics, and 1-year outcomes (physical health and readmission rates) were collected. The number of patients achieving 1.2 gram per kilogram per day of protein and 25 kilocalories per kilogram per day at 3 months, 6 months, and 12 months after ICU admission was recorded. The impact of dietary supplementation during the year was assessed. Baseline characteristics, intake barriers, and rehabilitation's influence on nutrition intake at 12 months were evaluated, along with the effect of inadequate intake on outcomes. After 12 months, only 10% of 60 patients achieved 1.2 g/kg/day protein intake, whereas 28% reached the advised 25 kcal/kg/day energy target. Supplementary feeding significantly increased protein intake at 3, 6, and 12 months (P = 0.003, P = 0.012, and P = 0.033, respectively) and energy intake at 3 months (P = 0.003). A positive relation was found between female sex and energy intake at 12 months after ICU admission (β = 4.145; P = 0.043) and taste issues were independently associated with higher protein intake (β = 0.363; P = 0.036). However, achieving upper-quartile protein or energy intake did not translate into improved physical health outcomes. Continuous and improved nutrition care is urgently needed to support patients in reaching nutrition adequacy.

Joblessness, decreased income, and disability in intensive care unit survivors of nontraumatic intracranial hemorrhage in South Korea

ObjectivesTo examine the proportions of unemployment, decreased household income, and newly acquired disability, and their impact on long-term mortality after intensive care unit (ICU) admission due to nontraumatic intracranial hemorrhage (IH). Materials and methodsThis nationwide population-based retrospective cohort study enrolled adult patients admitted to the ICU because of nontraumatic IH between 2010 and 2018 in South Korea. Patients who were alive ≥365 days after ICU admission were defined as nontraumatic IH survivors. ResultsIn total, 104,086 nontraumatic IH survivors were included in the final analysis. Among them, 7,225 (6.9 %) experienced job loss, 25,709 (24.7 %) experienced decreased household income, and 20,938 (20.1 %) had newly acquired disabilities, of whom 14,188 (13.6 %) had newly acquired brain disabilities. Male sex, increased duration of intensive care unit stay, comorbid status, hospital admission through the emergency room, nontraumatic intracerebral hemorrhage, receipt of surgery, mechanical ventilatory support, and increased total cost of hospitalization were associated with job loss, decreased household income, and newly acquired disabilities. However, these changes were not significantly associated with 2-year all-cause mortality (adjusted hazard ratio: 1.00, 95 % confidence interval: 0.95, 1.06; P = 0.997). ConclusionsMany nontraumatic IH survivors experienced unemployment, decreased household income, and newly acquired disability one year after ICU admission in South Korea. Some factors were potential risk factors for these changes, but the changes were not associated with 2-year all-cause mortality.

Blood-brain barrier breakdown in COVID-19 ICU survivors: an MRI pilot study.

Coronavirus disease 2019 (COVID-19) results in severe inflammation at the acute stage. Chronic neuroinflammation and abnormal immunological response have been suggested to be the contributors to neuro-long-COVID, but direct evidence has been scarce. This study aims to determine the integrity of the blood-brain barrier (BBB) in COVID-19 intensive care unit (ICU) survivors using a novel MRI technique. COVID-19 ICU survivors (n=7) and age and sex-matched control participants (n=17) were recruited from June 2021 to March 2023. None of the control participants were hospitalized due to COVID-19 infection. The COVID-19 ICU survivors were studied at 98.6 ± 14.9 days after their discharge from ICU. A non-invasive MRI technique was used to assess the BBB permeability to water molecules, in terms of permeability surface area-product (PS) in the units of mL/100 g/min. PS was significantly higher in COVID-19 ICU survivors (p=0.038) when compared to the controls, with values of 153.1 ± 20.9 mL/100 g/min and 132.5 ± 20.7 mL/100 g/min, respectively. In contrast, there were no significant differences in whole-brain cerebral blood flow (p=0.649) or brain volume (p=0.471) between the groups. There is preliminary evidence of a chronic BBB breakdown in COVID-19 survivors who had a severe acute infection, suggesting a plausible contributor to neurological long-COVID symptoms.

Novel risk score of mortality prediction for critical cardiogenic shock patients

Abstract Background Patients with critical cardiogenic shock have a high mortality rate. However, evidence for a specific scoring system for mortality prediction is obscure. Purpose This study aimed to identify independent predictors to build a reliable scoring system for survival prediction and risk identification in patients with cardiogenic shock. Methods This study enrolled critically ill patients with cardiogenic shock in the intensive care unit (ICU) between January 1, 2010, and December 31, 2021. A total of 1,607 patients were enrolled in this study. A novel scoring system for cardiogenic shock mortality prediction, the Kaohsiung Veterans General Hospital Cardiogenic Shock (KVHCS) score,was developed based on independent predictors. Further validation was performed using the Acute Physiology and Chronic Health Evaluation (APACHE) II score. Results The mean age of the patients was 67.6 ± 14 years, with male predominance (76%). Patients in the death subgroup were older (72.4 ± 12.8 vs. 66 ± 14 years, P &amp;lt; 0.001), had higher APACHE II (24.1 ± 9.9 vs. 14.6 ± 8.6, P &amp;lt; 0.001) scores, and had more comorbidities. A five-strata KVHCS score was constructed. Compared to the predictive ability of the APACHE II score (AUC = 0.75, P &amp;lt; 0.001) on ICU mortality, the KVHCS score (AUC = 0.87, P &amp;lt; 0.001) had a more powerful performance. It was also more reliable at predicting 30-day mortality (AUC = 0.81 vs. 0.73). Coronary artery disease (CAD) had the greatest contribution to mortality, whereas diabetes mellitus (DM) was a positive predictor of ICU discharge survival but had a negative impact on long-term outcomes. Conclusions For critical cardiogenic shock patients in the ICU, CAD was the most important factor negatively affecting ICU survival, whereas DM patients had better survival at ICU discharge but worse long-term outcome. The novel KVHCS score had better risk level prediction for mortality in cardiogenic shock patients than the traditional APACHE II score.Figure 3

Instruments to assess post-intensive care syndrome assessment: a scoping review and modified Delphi method study

BackgroundThe assessment of post-intensive care syndrome (PICS) is challenging due to the numerous types of instruments. We herein attempted to identify and propose recommendations for instruments to assess PICS in intensive care unit (ICU) survivors.MethodsWe conducted a scoping review to identify PICS follow-up studies at and after hospital discharge between 2014 and 2022. Assessment instruments used more than two times were included in the modified Delphi consensus process. A modified Delphi meeting was conducted three times by the PICS committee of the Japanese Society of Intensive Care Medicine, and each score was rated as not important (score: 1–3), important, but not critical (4–6), and critical (7–9). We included instruments with ≥ 70% of respondents rating critical and ≤ 15% of respondents rating not important.ResultsIn total, 6972 records were identified in this scoping review, and 754 studies were included in the analysis. After data extraction, 107 PICS assessment instruments were identified. The modified Delphi meeting reached 20 PICS assessment instrument recommendations: (1) in the physical domain: the 6-min walk test, MRC score, and grip strength, (2) in cognition: MoCA, MMSE, and SMQ, (3) in mental health: HADS, IES-R, and PHQ-9, (4) in the activities of daily living: the Barthel Index, IADL, and FIM, (5) in quality of life: SF-36, SF-12, EQ-5D-5L, 3L, and VAS (6), in sleep and pain: PSQI and Brief Pain Inventory, respectively, and (7) in the PICS-family domain: SF-36, HADS, and IES-R.ConclusionBased on a scoping review and the modified Delphi method, 20 PICS assessment instruments are recommended to assess physical, cognitive, mental health, activities of daily living, quality of life, sleep, and pain in ICU survivors and their families.

Abstract 18115: A Multidisciplinary Approach to Critical Cardiac Illness Survivorship: Cardiac Intensive Care Unit Recovery Clinic

Introduction: Cardiac intensive care unit (CICU) survivors have a high burden of morbidity and debility. Patients discharged from the CICU with a diagnosis of cardiogenic or septic shock, coma after cardiac arrest, or receive mechanical ventilation or mechanical circulatory support are referred by the CICU team to the Cardiac Intensive Care Unit Recovery Clinic (CICURC), a multidisciplinary clinic aimed at identifying barriers to return to function and optimizing medical and rehabilitation therapies. Aims: To define the cardiac profile and symptom burden of CICURC patients and compare outcomes to those referred but never attended. Methods: The medical records of sequential patients referred to the CICURC at our institution were retrospectively reviewed for clinical and outcome variables. Surveys were used to assess for cognitive, physical, or mental health impairment, findings of post-intensive care syndrome (PICS). Chi-squared test was performed to compare outcomes between groups. Results: From CICURC opening July 1, 2022, through May 27, 2023, 27 patients were referred, of whom 15 (56%) were seen in CICURC. The median age of patients seen in clinic was 61 years (IQR 47-74), 14 (93%) were male, 11 (73%) had an out-of-hospital cardiac arrest, 9 (60%) recovered from cardiogenic shock, of whom 5 (33%) were on mechanical circulatory support, and 12 received mechanical ventilation (80%). The median EF was 40% (IQR 25-50). From surveys, 5 patients screened positive for PICS (33%) and 6 were at risk for malnutrition (43%). Compared to those who did not attend clinic, only 1 (7%) CICURC attendee was readmitted within 30 days (vs. 3 [25%], p=0.18) and later died (vs. 4 [40%], p=0.04). Conclusions: CICU survivors have a high burden of disability after discharge. Multidisciplinary clinics focused on CICU recovery may reduce 30-day readmissions and mortality. Further research is needed on diagnosing PICS and therapies for recovery from critical cardiac illness.

Cognitive Impairment, Physical Impairment, and Psychological Symptoms in Intensive Care Unit Survivors.

Post-intensive care syndrome (PICS) affects 25% to 50% of adults who survive an intensive care unit (ICU) stay. Although the compounding of PICS impairments (cognitive, physical, and psychological) could intensify the syndrome, research on relationships among impairments is limited, particularly in patients with delirium. To examine associations among PICS impairments and examine delirium status and its relationship to PICS impairments at ICU discharge and 1 month later. A descriptive, correlational study of adults who survived an ICU stay. Participants completed measures for depression, anxiety, posttraumatic stress, physical function, functional status, and cognition at ICU discharge and 1 month later. Relationships among PICS impairments were examined with Spearman correlations; differences in impairments by delirium status were assessed with t tests. Of 50 enrolled participants, 46 were screened for PICS impairment at ICU discharge and 35 were screened 1 month later. Cognitive impairment was the most common impairment at both time points. A positive correlation was found between cognition and functional status at ICU discharge (ρ = 0.50, P = .001) and 1 month later (ρ = 0.54, P = .001). Cognition and physical functioning were positively correlated 1 month after discharge (ρ = 0.46, P = .006). The group with delirium had significantly lower functional status scores than the group without delirium at ICU discharge (P = .04). The findings suggest a moderate correlation between cognitive and physical impairments. This relationship should be explored further; ICU survivors with undiagnosed cognitive impairment may have delayed physical recovery and greater risk for injury.

Post Intensive Care Syndrome in Swiss Paediatric survivors and their Families (PICSS-PF): a national, multicentre, longitudinal study protocol

IntroductionPaediatric intensive care units (PICUs) survivors and their families often experience widespread morbidity and psychosocial consequences after discharge, known as post-intensive care syndrome in paediatrics (PICS-p). In Switzerland, more than...

Estimated glomerular filtration rate among intensive care unit survivors: From the removal of race coefficient to cystatin C-based equations

PurposeBlack race coefficient used in serum creatinine (sCr)-based estimated glomerular filtration rate (eGFR) calculation may perpetuate racial disparities. Among intensive care unit (ICU) survivors, sCr overestimates kidney function due to sarcopenia. Cystatin C (cysC) is a race- and muscle mass-independent eGFR marker. We investigated the impact of removing the race coefficient from sCr-based eGFR and compared cysC- and sCr-based eGFR in ICU survivors. Materials and methodsAmong 30,920 patients from 2 institutions in the Bronx and Boston, eGFR was calculated at hospital discharge using sCr-based equations with and without race coefficient (eGFRsCr2009 and eGFRsCr2021). In a subset with available cysC between ICU admission and 1-year follow-up, sCr- and cysC-based estimates were compared. ResultseGFRsCr2021 was higher than eGFRsCr2009 by a median of 4 ml/min/1.73 m2 among non-Black patients and lower by a median of 8 ml/min/1.73 m2 among Black patients. Removing race coefficient reclassified 12.9% of non-Black subjects and 16.1% of Black subjects to better and worse eGFR category, respectively, and differentially impacted the prevalence of kidney dysfunction between the institutions due to differences in racial composition. Among 51 patients with available cysC (108 measurements), cysC-based estimates were lower than sCr-based estimates (median difference 9 to 16 ml/min/1.73 m2), resulting in reclassification to worse eGFR category in 34% to 53.5% of measurements. ConclusionsAmong ICU survivors, removal of race coefficient leads to lower eGFR in Black patients and may contribute to overestimation of kidney function in non-Black patients. While cysC is rarely used, estimates based on this marker are significantly lower than those based on sCr.
