Association of baseline muscle mass with functional outcomes in intensive care unit survivors: A single-center retrospective cohort study in Korea.

In critical care settings, ultrasound (US) of the quadriceps muscle and Bioelectrical Impedance Analysis (BIA) are noninvasive and widely available tools to evaluate muscle mass. We studied whether baseline muscle mass affects physical function in intensive care unit (ICU) survivors after discharge. This retrospective review of a prospective cohort enrolled 30 patients admitted to the medical ICU between April 2016 and June 2018. On ICU admission, quadriceps muscle thickness and skeletal muscle mass were measured using US and BIA, respectively. Muscle strength and physical function were measured using handgrip dynamometry, the 6-min walk test, and the Barthel index questionnaire survey during every clinic visit at 1, 3, 6, and 12 months after hospital discharge. Skeletal muscle mass at ICU admission was statistically correlated with the 6-min walk distance (6MWD) and Barthel index score. The segmental lean mass of the right arm was also positively correlated with handgrip muscle strength at 6 months after discharge. Likewise, the correlation between quadriceps muscle thickness at ICU admission and 6MWD at 6 months after discharge was positive and statistically significant. Multivariate regression analysis showed that skeletal muscle mass was associated with a reduced 6MWD, but the length of ICU stay was not. The segmental lean mass of the right arm also showed a significant association with handgrip strength after discharge. Low muscle mass on ICU admission is associated with reduced muscle strength, causing impaired physical function after hospital discharge in ICU survivors.

Evaluating physiological barriers to oral intake in hospitalized patients: A secondary analysis.

Oral intake in hospitalized patients is frequently below estimated targets. Multiple physiological symptoms are proposed to impact oral intake, yet many have not been quantified objectively. To describe the challenges of objectively measuring physiological nutrition-impacting symptoms in hospitalized patients. A secondary analysis of data from a single-center, descriptive cohort study of physiological nutrition-impacting symptoms in intensive care unit (ICU) survivors and general medical patients was conducted. Demographic and clinical characteristics were extracted for patients who completed the original study and collected retrospectively for those who were screened and recruited but did not complete the original study. Reasons for patient exclusion from the original study were quantified from the screening database. Descriptive data are reported as mean ± SD, median [interquartile range], or number (percentage). ICU survivors and general medical patients were screened for inclusion in the original study between March 1 and December 23, 2021. Of the 644 patients screened, 97% did not complete the study, with 93% excluded at screening. Of the 266 ICU survivors and 398 general medical patients screened, 89% and 95% were excluded, respectively. Major exclusion criteria included the inability to follow commands or give informed consent (n = 155, 25%), the inability to consume the easy-to-chew and thin-fluid buffet meal, and imminent discharge (both, n = 120, 19%). Understanding physiological factors that drive reduced oral intake in hospitalized patients is challenging. Exclusion criteria required to objectively quantify physiological nutrition-impacting symptoms significantly preclude participation and likely act as independent barriers to oral intake.

Long-term outcomes and associated factors among intensive care unit survivors in a low-income country: a multicenter prospective cohort study

ObjectivePost-ICU survivors face higher mortality and often require costly rehabilitation or palliative care, such as occupational therapy, physiotherapy and hospice. However, there is a lack of data quantifying the demand for these services, particularly in developing countries like Uganda. Therefore, this prospective cohort study aimed to investigate the 90-day mortality rate, functional status, and mortality risk factors among 121 ICU patients discharged from three tertiary hospital ICUs in Uganda by tracking their vital and physical functional status for three months with follow-ups on days 30, 60, and 90, and identifying risk factors through Cox regression.ResultsThe study revealed that 18 out of 121 ICU patients (14.88%, 95% CI: 9.52-22.51%) died within 90 days post-discharge, while 36.36% achieved normal physical functional status. Factors associated with higher 90-day mortality included raised intracranial pressure (HR 1.92, 95% CI: 1.76–2.79, p = 0.04), acute kidney injury (HR 4.13, 95% CI: 2.16–7.89, p < 0.01), and renal replacement therapy (HR 3.34, 95% CI: 2.21–5.06, p < 0.01). The high mortality rate and the fact that nearly two-thirds of patients did not attain normal functional status 90 days post discharge underscores the need for enhanced post-ICU rehabilitation services.

A prospective cohort study on cognitive and psychological outcomes in COVID-19 ICU survivors at 3 months of follow up.

The Outcomes - Short and Long term in ICU patient with COVID-19 "OUTSTRIP COVID-19" study was initiated to assess overall mortality, physical and psychiatric co-morbidities, reduction in lung function, and the ability to return to work post-ICU discharge with a follow-up period of 2 years in COVID-19 patients admitted to ICUs in Qatar. This paper focuses on the prevalence of cognitive impairment, depression, anxiety, and stress at baseline and 3 months after ICU discharge. This prospective cohort study included 100 ICU survivors reviewed at baseline within 7 weeks of ICU discharge, with a 3-month follow-up. Demographics, clinical characteristics, and relevant medical history were collected at baseline. Cognitive outcomes were assessed using the Montreal Cognitive Assessment-Basic (MoCA-B) tool, while psychological outcomes were evaluated using the Depression Anxiety and Stress Scale-21 (DASS-21). At baseline, 72% of ICU survivors exhibited mild cognitive impairment, which significantly improved to 56% at 3 months. However, severe cognitive impairment persisted in 20% of survivors at 3 months.For psychological outcomes, the mean depression score remained below 9 (5.64 ± 6.90) at both time points, with no significant change. At baseline, 25% of survivors had clinical depression, which reduced to 16% at 3 months.The mean anxiety score at baseline (9.35 ± 8.50) significantly decreased to 6.51 ± 7.74 (p = 0.002) at 3 months. Anxiety was not reported by 48% of survivors at baseline and this increased to 66% at 3 months. Severe to extremely severe anxiety decreased from 19% to 12% during the same period.The mean stress score at baseline (8.34 ± 8.07) did not significantly change at 3 months. At baseline, 18% experienced stress, which decreased to 12% at 3 months, with 5.3% facing severe to extremely severe stress. COVID-19 ICU survivors experience significant cognitive impairment, anxiety, and stress. While cognitive impairment and anxiety showed improvements at 3 months, depression and stress remained unchanged. These outcomes strongly emphasize the requirement for thorough post-ICU care and comprehensive mental health assistance for individuals recovering from COVID-19. Customized interventions and additional research endeavors are crucial to effectively manage the cognitive and psychological consequences faced by these patients. The exploration of telemonitoring and innovative approaches can offer avenues to enhance the overall quality of life for survivors. Further investigation should encompass extended timeframes to analyze prolonged effects and consider the broader socioeconomic impact.

Long term cognitive dysfunction among critical care survivors: associated factors and quality of life—a multicenter cohort study

ObjectivesTo identify the prevalence and associated factors of cognitive dysfunction, 1 year after ICU discharge, among adult patients, and it´s relation with quality of life.MethodsMulticenter, prospective cohort study including ICUs of 10 tertiary hospitals in Brazil, between May 2014 and December 2018. The patients included were 452 adult ICU survivors (median age 60; 47.6% women) with an ICU stay greater than 72 h.ResultsAt 12 months after ICU discharge, a Montreal Cognitive Assessment (tMOCA) telephone score of less than 12 was defined as cognitive dysfunction. At 12 months, of the 452 ICU survivors who completed the cognitive evaluation 216 (47.8%) had cognitive dysfunction.In multivariable analyses, the factors associated with long-term (1-year) cognitive dysfunction were older age (Prevalence Ratio–PR = 1.44, P < 0.001), absence of higher education (PR = 2.81, P = 0.005), higher comorbidities on admission (PR = 1.089; P = 0.004) and delirium (PR = 1.13, P < 0.001). Health-related Quality of life (HRQoL), assessed by the mental and physical dimensions of the SF-12v2, was significantly better in patients without cognitive dysfunction (Mental SF-12v2 Mean difference = 2.54; CI 95%, − 4.80/− 0.28; p = 0.028 and Physical SF-12v2 Mean difference = − 2.85; CI 95%, − 5.20/− 0.50; P = 0.018).ConclusionsDelirium was found to be the main modifiable predictor of long-term cognitive dysfunction in ICU survivors. Higher education consistently reduced the probability of having long-term cognitive dysfunction. Cognitive dysfunction significantly influenced patients’ quality of life, leading us to emphasize the importance of cognitive reserve for long-term prognosis after ICU discharge.

Changes in quality of life 1 year after intensive care: a multicenter prospective cohort of ICU survivors

BackgroundWith survival rates of critical illness increasing, quality of life measures are becoming an important outcome of ICU treatment. Therefore, to study the impact of critical illness on quality of life, we explored quality of life before and 1 year after ICU admission in different subgroups of ICU survivors.MethodsData from an ongoing prospective multicenter cohort study, the MONITOR-IC, were used. Patients admitted to the ICU in one of eleven participating hospitals between July 2016 and June 2021 were included. Outcome was defined as change in quality of life, measured using the EuroQol five-dimensional (EQ-5D-5L) questionnaire, and calculated by subtracting the EQ-5D-5L score 1 day before hospital admission from the EQ-5D-5L score 1 year post-ICU. Based on the minimal clinically important difference, a change in quality of life was defined as a change in EQ-5D-5L score of ≥ 0.08. Subgroups of patients were based on admission diagnosis.ResultsA total of 3913 (50.6%) included patients completed both baseline and follow-up questionnaires. 1 year post-ICU, patients admitted after a cerebrovascular accident, intracerebral hemorrhage, or (neuro)trauma, on average experienced a significant decrease in quality of life. Conversely, 11 other subgroups of ICU survivors reported improvements in quality of life. The largest average increase in quality of life was seen in patients admitted due to respiratory disease (mean 0.17, SD 0.38), whereas the largest average decrease was observed in trauma patients (mean -0.13, SD 0.28). However, in each of the studied 22 subgroups there were survivors who reported a significant increase in QoL and survivors who reported a significant decrease in QoL.Conclusions This large prospective multicenter cohort study demonstrated the diversity in long-term quality of life between, and even within, subgroups of ICU survivors. These findings emphasize the need for personalized information and post-ICU care.Trial registration: The MONITOR-IC study was registered at ClinicalTrials.gov: NCT03246334 on August 2nd 2017.

Risks of developing major psychiatric disorders among child and adolescent intensive care unit survivors

BackgroundThe mental health of child and adolescent intensive care unit (ICU) survivors is increasingly being researched. However, the literature on how various types of critical illness influence specific psychiatric disorders remains limited. MethodsThis study analyzed the data of 8704 child and adolescent ICU survivors and 87,040 age-, sex-, family income–, and residence-matched controls who were followed from enrollment to the end of 2013; the data covered the period from 1996 to 2013 and were extracted from a nationwide data set. The primary outcomes were the risks of five major psychiatric disorders (MPDs), namely schizophrenia, bipolar disorder (BD), major depressive disorder (MDD), obsessive compulsive disorder (OCD), and posttraumatic stress disorder (PTSD). ResultsRelative to the controls, the child and adolescent ICU survivors (mean age = 10.33 years) exhibited higher risks of developing five MPDs. The associated hazard ratios (HRs) and confidence intervals (CIs) are as follows: PTSD, HR = 4.67, 95 % CI = 2.42–9.01; schizophrenia, HR = 3.19, 95 % CI = 2.27–4.47; BD, HR = 2.02, 95 % CI = 1.33–3.05; OCD, HR = 1.96, 95 % CI = 1.21–3.16; and MDD, HR = 1.68, 95 % CI = 1.44–1.95. The risks of developing MPDs varied across multiple types of critical illness related to ICU admission. ConclusionsThe risks of MPDs were significantly higher among the child and adolescent ICU survivors than among the controls. The development of appropriate MPD prevention strategies should be emphasized for this vulnerable population.

Impact of Protein Intake after Intensive Care Unit on Discharge Destination for Critically Ill Patients: A Single-Center Prospective Observational Study

Introduction: Although nutritional therapy may be able to enable intensive care unit (ICU) survivors to return home instead of being discharged to a rehabilitation facility, post-ICU discharge nutritional therapy lacks investigation. This study evaluated the impact of nutritional therapy after ICU on discharge destination in critically ill patients. Methods: We enrolled consecutive adult patients who spent >72 h in the ICU from December 2020 to March 2023. The primary outcome was discharge destination. Energy and protein intake during the ICU stay and on days 7 and 14 after ICU discharge were evaluated. The target protein intake during the intensive treatment and general ward phases were 0.8 and 1.0 g/kg/day, respectively. Patients were categorized into home discharge (group A) and rehabilitation transfer (group B) groups. Factors affecting the discharge destination were evaluated using logistic regression analysis. Results: Of the 183 patients included, 134 belonged to group A and 49 to group B. In group A, more patients reached the protein intake target than in group B. Logistic regression analysis identified achieving the protein intake target as an independent predictor of home discharge. Conclusion: Further studies are required to confirm the relationship between nutritional therapy during general ward and patient outcomes.

Physical function measures in ICU survivors, where to now? A scoping review

Background. Growing evidence is describing the long-term morbidity experienced by critical illness survivors, a major contributing factor being impaired physical function. Consensus is yet to be reached on which physical function measures should be included in this population. This review aimed to describe physical functioning measurement instruments used in longitudinal studies of critical illness survivors, based on the International Classification of Function (ICF). Methods. An electronic database search of EbscoHost, Web of Science and Scopus was conducted from inception to November 2023. Two reviewers independently applied the inclusion and exclusion criteria to titles, abstracts and full text-studies. Extracted data included year of publication; country; participant age; follow-up timeframes and physical measurement instruments used. Instruments were classified according to ICF domains. Results. Eighty studies published between 1995 and November 2023 were included. Forty-four different outcome measures were identified. Most studies (68) included multiple followed-up points and were completed within a year, and few studies (12) follow-up beyond a year. Based on the ICF, 11 (25%) instruments measured impairments and 33 (75%) activity limitations. Muscle power functions were the most frequently measured impairment (65%), utilising manual muscle testing (37.3%). The six-minute walk test (6MWT) was the most frequently used instrument in the activity/participation domain (31.6%). Only one instrument addressed all five the physical activity/participation domains, while the majority focused on mobility domain. Conclusions. Multiple tools are used to report on physical deficits experienced by ICU survivors, either measuring impairments or activity/ participation limitations. Most studies report on physical function within the first year of survival. The heterogeneity and inconsistency over time of instruments used prevents synthesis of data to determine intervention efficacy. The validity, predictive value and sensitivity of the reported measures within ICU survivors needs to be established, only then can intervention studies be designed to measure effectiveness.

Association between protein intake and functional capacity in critically ill patients: A retrospective cohort study.

Intensive care unit (ICU) protein benchmarks are based on mortality and morbidity; whether these targets also support functional recovery is unknown. We assessed whether different protein doses influenced patients' functional capacity, measured by the Chelsea Physical Assessment score (CPAx). Single-center retrospective cohort study on ICU survivors with length of stay ≥7 days admitted between October 2014 and September 2020. Eligible patients were divided according to protein intake (g/kg/day): low (<0.8), medium (0.8-1.19), high (1.2-1.5), and very high (>1.5). Protein dose effect on CPAx was assessed at ICU discharge with analysis of covariance adjusting for age, illness severity, hospital length of stay before ICU admission, time to start nutrition support, and mechanical ventilation duration. We also investigated effect modification by energy intake and nutrition status. Enrolled patients (n = 531) were similar for age, nutrition status, and illness severity across groups. CPAxs were nonlinearly associated with protein doses and similar among low, medium, and very high groups. The CPAx for the high group was statistically different (P = 0.014), indicating that the data of three groups could be pooled. Mean CPAx difference remained statistically significant after adjusting for confounding variables (3.9 ± 1.8, P = 0.029 in the four-group model, and 2.7 ± 0.9, P = 0.003 in the pooled two-group model). Energy intake was equivalent between groups and did not modify CPAx. The high group had superior CPAx in both well-nourished and malnourished patients, indicating nutrition status was not an effect modifier. Protein dose 1.2-1.5 g/kg/day was associated with superior functional capacity at ICU discharge compared with other doses. Neither energy intake nor nutrition status modified functional capacity across groups; therefore, the results appear to be influenced by 1.2-1.5 g/kg/day.

One-year outcomes in COVID-19 and non-COVID-19 intensive care unit survivors

PurposeTo determine differences in one-year multi-domain health outcomes in COVID-19 and non-COVID-19 intensive care unit (ICU) survivors. Materials and methodsAdult ICU survivors treated for COVID-19 were compared to a control group consisting of survivors admitted for respiratory distress due to other causes, i.e. non-COVID-19 ARDS or pneumonia. Occurrence of physical (frailty, fatigue, physical symptoms), mental (anxiety, depression, post-traumatic stress) and cognitive symptoms, and quality of life (QoL) scores were measured, using validated questionnaires, before and one year after ICU treatment. ResultsIn total, 506 COVID-19 survivors could be compared to 228 non-COVID-19 survivors. At one-year follow-up, COVID-19 ICU survivors had less physical (76.2% vs. 86.9%, p = 0.001) and mental symptoms (32.0% vs. 47.1%, p < 0.001) than the control group. Cognitive symptoms were comparable (22.5% vs. 17.2%, p = 0.12). However, compared to pre-ICU health symptoms and scores, COVID-19 survivors experienced an increase in symptom occurrence rates in all domains and a decrease in QoL, whereas the control group only experienced an increase in mental and cognitive symptoms, with a similar QoL at one-year follow-up. ConclusionsCOVID-19 ICU survivors experience equal or less health problems but a greater decline in QoL one year after ICU admission compared to non-COVID-19 ARDS or pneumonia survivors.

Impact of Muscle Changes Assessed by Ultrasonography on Muscle Strength and Functioning after ICU Discharge: A Systematic Review with Meta-Analysis.

Ultrasonography has been used to identify structural, quantitative, and qualitative muscle changes. These changes have been assessed in different muscles during ICU stays; however, it is unclear if it can predict functioning after ICU discharge. To analyze the relationship between muscle changes assessed by ultrasonography and the strength and functioning of ICU survivors. A systematic review with a meta-analysis was performed according to the MOOSE guidelines and registered in PROSPERO. Searches of the following databases were performed by two of the authors: PubMed, Cinahl, Embase, Scopus, LILACS, Web of Science, and Science Direct. Qualitative analysis was performed using NOS and AHRQ scales. Meta-analysis was performed using the "R", "metafor" package. Heterogeneity was assessed by I2 and Cochran's Q test. Meta-regression analyses were performed to verify the moderators, and funnel plots and Egger's regression intercept test were used to analyze the publication bias. Sixteen articles were included in the qualitative assessment, and nine were used in the quantitative assessment. There is evidence of correlations between MT and muscle strength (r = 0.20 [0.11; 0.27]; p < 0.0001), and MT (r = 0.35 [0.19; 0.49]; p < 0.0001), CSA (r = 0.30 [0.10; 0.47]; p = 0.0038), EI (r = -0.29 [-0.53; -0.01]; p = 0.043) and mobility. In the subgroup analyses, some evidence of a correlation between specific muscles and strength and mobility were found. There is evidence for the correlation between muscle characteristics assessed by US and functioning outcomes.

Hematological Markers as Predictors of ICU Admission in COVID-19 Patients: A Case-Control Study From a Tertiary Hospital.

COVID-19 illness severity ranges from mild- to life-threatening cases necessitating critical care. Rapid prediction of disease severity and the need for critical care support in COVID-19 patients remain essential, not only for current management but also for preparedness in future pandemics. This study aimed to assess hematological parameters as predictors of intensive care unit (ICU) admission and survival in COVID-19 patients, providing insights applicable to a broad range of infectious diseases. A case-control study was conducted at Hospital Raja Perempuan Zainab II, a tertiary referral hospital in Kelantan, Malaysia, from March 2020 to August 2021. Demographics, clinical, and laboratory data were retrieved from patients' medical records. Statistical analyses, including the Chi-square (χ2) test, independent t-tests, and simple and multiple logistic regressions, were used to analyze the data. A receiver operating characteristic (ROC) curve analysis was conducted to assess the accuracy of the predictors. The median age was 51 years, with females comprising 56.7% (n=148) and males 43.3% (n=113). A total of 88.5% of patients were admitted to non-ICU wards, with a mortality rate of 5.7%. Significant differences were observed in the distribution of hematological parameters between ICU-admitted and non-admitted patients. Neutrophil (OR: 23.96, 95% CI: 7.296-78.675) and white blood cell (WBC) count (OR: 36.677, 95% CI: 2.086-644.889) were the most significant predictors for ICU admission and survival, respectively. WBC and neutrophil counts exhibited high predictive value for ICU admission, while WBC, neutrophil, lymphocyte, and immature granulocyte (IG) counts were significant predictors of survival status among COVID-19 patients. These findings underscore the continued relevance of hematological markers in managing severe respiratory infections and improving critical care triage, with implications for current and future healthcare challenges.

Antidepressant drug use after intensive care: a nationwide cohort study

Modern intensive care has improved survival rates, but emerging evidence suggests a high prevalence of post-intensive care unit (ICU) health problems, including post-traumatic stress disorder, depression and anxiety. These symptoms may have a detrimental effect on quality of life and increase mortality. The primary objective of this study is to examine the extent of initiation of antidepressant medication among ICU survivors and identify the factors associated with its usage. The secondary objective is to investigate whether the use of these medications is linked to an increased mortality. The nationwide study cohort included 125,130 ICU survivors admitted between 2010 and 2017. Within the first 3 months after ICU discharge, 7% of patients initiated antidepressant medication, by 1 year 15.5% had started medication. We found no tendency to a decrease during the 2-year follow-up period. Factors associated with antidepressant use included middle age, female sex, psychiatric and somatic comorbid conditions, substance dependence, higher illness severity, and longer ICU stay. Antidepressant users had a higher mortality rate, and deaths due to external causes and suicide were more frequent in this group. This study emphasizes the importance of detecting and addressing depression in ICU survivors to improve their quality of life and reduce mortality rates.

Post-intensive care syndrome screening: a French multicentre survey

BackgroundPost-intensive care syndrome (PICS), defined as physical, cognitive, and mental-health symptoms persisting long after intensive-care-unit (ICU) discharge, is increasingly recognised as a healthcare priority. Data on screening for PICS are sparse. Our objective here was to describe post-ICU screening in France, with special attention to visit availability and evaluations done during visits.MethodsWe conducted an online multicentre survey by emailing an anonymous 43-item questionnaire to French ICUs. For each ICU, a single survey was sent to either the head or the intensivist in charge of follow-up visits.ResultsOf 252 ICUs invited to participate, 161 (63.9%) returned the completed survey. Among them, 46 (28.6%) offered follow-up visits. Usually, a single visit led by an intensivist was scheduled 3 to 6 months after ICU discharge. Approximately 50 patients/year/ICU, that is, about 5% of admitted patients, attended post-ICU visits. The main criteria used to select patients for follow-up were ICU stay and/or invasive mechanical ventilation duration longer than 48 h, cardiac arrest, septic shock, and acute respiratory distress syndrome. Among ICUs offering visits, 80% used validated instruments to screen for PICS. Of the 115 ICUs not offering follow-up, 50 (43.5%) indicated an intention to start follow-up within the next year. The main barriers to offering follow-up were lack of available staff and equipment or not viewing PICS screening as a priority. Half the ICUs offering visits worked with an established network of post-ICU care professionals, and another 17% were setting up such a network. Obstacles to network creation were lack of interest among healthcare professionals and lack of specific training in PICS.ConclusionOnly a small minority of ICU survivors received follow-up designed to detect PICS. Less than a third of ICUs offered follow-up visits but nearly another third planned to set up such visits within the next year. Recommendations issued by French health authorities in 2023 can be expected to improve the availability and standardisation of post-ICU follow-up.

Onset of Prolonged High-Potency Benzodiazepine Use Among ICU Survivors: A Nationwide Cohort Study.

Exposure to critical illness and intensive care may lead to long-term psychologic and physical impairments. To what extent ICU survivors become prolonged users of benzodiazepines after exposure to critical care is not fully explored. This study aimed to describe the extent of onset of prolonged high-potency benzodiazepine use among ICU survivors not using these drugs before admission, identify factors associated with this use, and analyze whether such usage is associated with increased mortality. Retrospective cohort study. Sweden, including all registered ICU admissions between 2010 and 2017. ICU patients surviving for at least 3 months, not using high-potency benzodiazepine before admission, were eligible for inclusion. Admission to intensive care. A total of 237,904 patients were screened and 137,647 were included. Of these 5338 (3.9%) became prolonged users of high-potency benzodiazepines after ICU discharge. A peak in high-potency benzodiazepine prescriptions was observed during the first 3 months, followed by sustained usage throughout the follow-up period of 18 months. Prolonged usage was associated with older age, female sex, and a history of both somatic and psychiatric comorbidities, including substance abuse. Additionally, a longer ICU stay, a high estimated mortality rate, and prior consumption of low-potency benzodiazepines were associated with prolonged use. The risk of death between 6 and 18 months post-ICU admission was significantly higher among high-potency benzodiazepine users, with an adjusted hazard ratio of 1.8 (95% CI, 1.7-2.0; p < 0.001). No differences were noted in causes of death between users and nonusers. Despite the lack of evidence supporting long-term treatment, prolonged usage of high-potency benzodiazepines 18 months following ICU care was notable and associated with an increased risk of death. Considering the substantial number of ICU admissions, prevention of benzodiazepine misuse may improve long-term outcomes following critical care.

Symptoms of anxiety, depression, and post-traumatic stress disorder 6 weeks and 6 months after ICU: Six out of 10 survivors affected.

Mental health conditions such as depression, anxiety and post-traumatic stress disorder (PTSD) are being increasingly recognised as common adverse outcomes for critical illness survivors. These conditions can have lasting consequences on their wellbeing, ability to return to their pre-illness level of functioning and health-related quality of life. There is a paucity of South African data in terms of the psychological aspects of the post-intensive care unit (ICU) syndrome. To identify and characterise patients who suffered from significant symptoms of mental health disease and poor mental health- related quality of life after ICU admission and who may benefit from appropriate referral, further investigation and medical intervention. Critically ill patients in a multidisciplinary tertiary ICU were prospectively enrolled upon ICU discharge. Survivors were screened for anxiety, depression and post-traumatic stress syndrome at 6 weeks and 6 months after hospital discharge. The Hospital Anxiety and Depression Score (HADS) and the Impact Of Events Scale - Revised (IES-R) were used as screening tools. The mental component summary score (MCS) of the RAND short form-36 was used to determine the effect of psychological symptoms on health-related quality of life (HRQOL). The median age of the 107 ICU survivors was 42 years, and half of them were admitted for complications of COVID-19. Six out of every 10 ICU survivors experienced significant symptoms of anxiety, depression and/or PTSD at follow-up. At the 6-month study visit, 4 out of every 10 patients were experiencing significant psychological symptoms. Those affected had a significantly lower mental HRQOL when compared with those who were unaffected. More than half of those affected had co-occurrence of psychological symptoms. Significant symptoms of anxiety were common, with 5 out of every 10 participants experiencing significant symptoms at either, or both, of the study visits. More than 3 out of 10 of affected patients' symptoms only occurred after the 6-week visit. Associations for significant psychological symptoms comprised female sex, younger age, a diagnosis of trauma and frightening memories of the ICU admission. The burden of mental health disease in ICU survivors is substantial, affecting their HRQOL. Six out of 10 patients experienced symptoms of anxiety, depression and PTSD, and more than half of those affected experienced co-occurrence of the conditions. A third of those affected developed these symptoms only beyond 6 weeks after hospital discharge. A potentially modifiable association with psychological symptoms was frightening memories of the ICU stay.

Factors affecting perceived caregiver burden: caregivers of trauma patients discharged from the intensive care unit

Background Caregivers to intensive care unit survivors are vulnerable to caregiver burden, which has been demonstrated to have consequences to patients’ and caregivers’ mental and physical health. Potentially modifiable factors should be explored so that interventions may be developed. Methods Ninety-one anticipated caregivers were prospectively assessed both at a southwestern trauma intensive care unit during their patient’s admission and at home via remote interview 3 months after intensive care unit admission. Caregiver depression, posttraumatic stress symptoms, experiences, and perceived burden were assessed. Results At follow up, there was a significant negative correlation between caregiver burden and understanding of their patient’s condition (P < 0.001) and intensive care unit events (P = 0.008). Caregivers with lower understanding of their patient’s injury/illness had significantly greater depressive symptoms (P = 0.04). Conclusions Education and knowledge of intensive care unit events regarding their patient may influence perceived burden among caregivers. Interventions to orient caregivers to intensive care unit events are suggested to reduce caregiver and healthcare system burden.

Marked hyperferritinemia in critically ill cancer patients.

To investigate characteristics and outcomes of critically ill cancer patients with marked hyperferritinemia. A single-center retrospective analysis comprising cancer patients with a ferritin level >10.000 μg/L treated in the intensive care unit (ICU) between 2012 and 2022 was conducted. A total of 117 patients were included in the analysis. The median age was 59 years (range: 15-86 years). Females accounted for 48% of cases. 90% of patients had a hematologic malignancy. The median maximum ferritin level was 27.349 μg/L (range: 10.300-426.073 μg/L). The diagnostic criteria of septic shock were fulfilled in 51% of cases; 31% of patients had hemophagocytic lymphohistiocytosis (HLH) according to the HLH-2004 criteria. Mechanical ventilation, renal replacement therapy and the use of vasopressors were necessary in 59%, 35% and 70% of cases, respectively. The ICU, hospital, 90-day and 1-year survival rates were 33.3%, 23.1%, 23.7% and 11.7%. Patients with septic shock had a worse survival than those without septic shock (p = .001); the survival of patients who fulfilled the HLH-2004 criteria did not differ from those who did not (p = .88). Critically ill cancer patients with marked hyperferritinemia have poor outcomes. The present data may help to make informed decisions for this patient group.

Microbiological risk factors, ICU survival, and 1-year survival in hematological patients with pneumonia requiring invasive mechanical ventilation

PurposeTo identify pathogenic microorganisms and microbiological risk factors causing high morbidity and mortality in immunocompromised patients requiring invasive mechanical ventilation due to pneumonia.MethodsA retrospective single-center study was performed at the intensive care unit (ICU) of the Department of Internal Medicine at Heidelberg University Hospital (Germany) including 246 consecutive patients with hematological malignancies requiring invasive mechanical ventilation due to pneumonia from 08/2004 to 07/2016. Microbiological and radiological data were collected and statistically analyzed for risk factors for ICU and 1-year mortality.ResultsICU and 1-year mortality were 63.0% (155/246) and 81.0% (196/242), respectively. Pneumonia causing pathogens were identified in 143 (58.1%) patients, multimicrobial infections were present in 51 (20.7%) patients. Fungal, bacterial and viral pathogens were detected in 89 (36.2%), 55 (22.4%) and 41 (16.7%) patients, respectively. Human herpesviruses were concomitantly reactivated in 85 (34.6%) patients. As significant microbiological risk factors for ICU mortality probable invasive Aspergillus disease with positive serum-Galactomannan (odds ratio 3.1 (1.2-8.0), p = 0.021,) and pulmonary Cytomegalovirus reactivation at intubation (odds ratio 5.3 (1.1–26.8), p = 0.043,) were identified. 1-year mortality was not significantly associated with type of infection. Of interest, 19 patients had infections with various respiratory viruses and Aspergillus spp. superinfections and experienced high ICU and 1-year mortality of 78.9% (15/19) and 89.5% (17/19), respectively.ConclusionsPatients with hematological malignancies requiring invasive mechanical ventilation due to pneumonia showed high ICU and 1-year mortality. Pulmonary Aspergillosis and pulmonary reactivation of Cytomegalovirus at intubation were significantly associated with negative outcome.
