Predictors of Major Depressive Disorder following Intensive Care of Chronically Critically Ill Patients.

Objective Major depressive disorder (MDD) is a common condition following treatment in the Intensive Care Unit (ICU). Long-term data on MDD in chronically critically ill (CCI) patients are scarce. Hence, the primary aim of the present study was to investigate the frequency and predictors of MDD after intensive care of CCI patients. Materials and Methods In a prospective cohort study, patients with long-term mechanical ventilation requirements (n=131) were assessed with respect to a diagnosis of MDD, using the Structured Clinical Interview for DSM-IV, three and six months after the transfer from acute ICU to post-acute ICU. Sociodemographic, psychological, and clinical risk factors with p values ≤ 0.1 were identified in a univariate logistic regression analysis and entered in a multivariable logistic regression model. A mediator analysis was run using the bootstrapping method, testing the mediating effect of perceived helplessness during the ICU stay, between the recalled traumatic experience from the ICU and a post-ICU MDD. Results 17.6% (n=23) of the patients showed a full- or subsyndromal MDD. Perceived helplessness, recalled experiences of a traumatic event from the ICU, symptoms of acute stress disorder, and the diagnosis of posttraumatic stress disorder (PTSD) after ICU could be identified as significant predictors of MDD. In a mediator analysis, perceived helplessness could be proved as a mediator. Conclusions Every fifth CCI patient suffers from MDD up to six months after being discharged from ICU. Particularly, perceived helplessness during the ICU stay seems to mainly affect the long-term evolvement of MDD. CCI patients with symptoms of acute stress disorder/PTSD should also be screened for MDD.

Self-reported fatigue following intensive care of chronically critically ill patients: a prospective cohort study

BackgroundProtracted treatment on intensive care unit (ICU) sets the patients at increased risk for the development of chronic critical illness (CCI). Muscular and cardio-respiratory deconditioning are common long-term sequelae, going along with a state of chronic fatigue. At present, findings regarding the frequency, long-term course, and associated factors of self-reported fatigue following ICU treatment of CCI patients are lacking.MethodsCCI patients with the diagnosis of critical illness polyneuropathy/myopathy (CIP/CIM) were assessed at three time points. Four weeks following the discharge from ICU at acute care hospital (t1), eligibility for study participation was asserted. Self-reported fatigue was measured using the Multidimensional Fatigue Inventory (MFI-20) via telephone contact at 3 (t2, n = 113) and 6 months (t3, n = 91) following discharge from ICU at acute care hospital.ResultsAt both 3 and 6 months, nearly every second CCI patient showed clinically relevant fatigue symptoms (t2/t3: n = 53/n = 51, point prevalence rates: 46.9%/45.1%). While total fatigue scores remained stable in the whole sample, female patients showed a decrease from 3 to 6 months. The presence of a coronary heart disease, the perceived fear of dying at acute care ICU, a diagnosis of major depression, and the perceived social support were confirmed as significant correlates of fatigue at 3 months. At 6 months, male gender, the number of medical comorbidities, a diagnosis of major depression, and a prior history of anxiety disorder could be identified. A negative impact of fatigue on the perceived health-related quality of life could be ascertained.ConclusionsNearly every second CCI patient showed fatigue symptoms up to 6 months post-ICU. Patients at risk should be informed about fatigue, and appropriate treatment options should be offered to them.Trial registrationThe present study was registered retrospectively at the German Clinical Trials Register (date of registration: 13th of December 2011; registration number: DRKS00003386).

Innate Immunity in the Persistent Inflammation, Immunosuppression, and Catabolism Syndrome and Its Implications for Therapy

Clinical and technological advances promoting early hemorrhage control and physiologic resuscitation as well as early diagnosis and optimal treatment of sepsis have significantly decreased in-hospital mortality for many critically ill patient populations. However, a substantial proportion of severe trauma and sepsis survivors will develop protracted organ dysfunction termed chronic critical illness (CCI), defined as ≥14 days requiring intensive care unit (ICU) resources with ongoing organ dysfunction. A subset of CCI patients will develop the persistent inflammation, immunosuppression, and catabolism syndrome (PICS), and these individuals are predisposed to a poor quality of life and indolent death. We propose that CCI and PICS after trauma or sepsis are the result of an inappropriate bone marrow response characterized by the generation of dysfunctional myeloid populations at the expense of lympho- and erythropoiesis. This review describes similarities among CCI/PICS phenotypes in sepsis, cancer, and aging and reviews the role of aberrant myelopoiesis in the pathophysiology of CCI and PICS. In addition, we characterize pathogen recognition, the interface between innate and adaptive immune systems, and therapeutic approaches including immune modulators, gut microbiota support, and nutritional and exercise therapy. Finally, we discuss the future of diagnostic and prognostic approaches guided by machine and deep-learning models trained and validated on big data to identify patients for whom these approaches will yield the greatest benefits. A deeper understanding of the pathophysiology of CCI and PICS and continued investigation into novel therapies harbor the potential to improve the current dismal long-term outcomes for critically ill post-injury and post-infection patients.

Activity and Circadian Rhythm of Sepsis Patients in the Intensive Care Unit.

Early mobilization of critically ill patients in the Intensive Care Unit (ICU) can prevent adverse outcomes such as delirium and post-discharge physical impairment. To date, no studies have characterized activity of sepsis patients in the ICU using granular actigraphy data. This study characterizes the activity of sepsis patients in the ICU to aid in future mobility interventions. We have compared the actigraphy features of 24 patients in four groups: Chronic Critical Illness (CCI) sepsis patients in the ICU, Rapid Recovery (RR) sepsis patients in the ICU, non-sepsis ICU patients (control-ICU), and healthy subjects. We used a total of 15 statistical and circadian rhythm features extracted from the patients' actigraphy data collected over a five-day period. Our results show that the four groups are significantly different in terms of activity features. In addition, we observed that the CCI and control-ICU patients show less regularity in their circadian rhythm compared to the RR patients. These results show the potential of using actigraphy data for guiding mobilization practices, classifying sepsis recovery subtype, as well as for tracking patients' recovery.

Fatigue in chronically critically ill patients following intensive care - reliability and validity of the multidimensional fatigue inventory (MFI-20)

BackgroundFatigue often occurs as long-term complication in chronically critically ill (CCI) patients after prolonged intensive care treatment. The Multidimensional Fatigue Inventory (MFI-20) has been established as valid instrument to measure fatigue in a wide range of medical illnesses. Regarding the measurement of fatigue in CCI patients, the psychometric properties of the MFI-20 have not been investigated so far. Thus, the present study examines reliability and validity of the MFI-20 in CCI patients.MethodsA convenience sample of n = 195 patients with Critical Illness Polyneuropathy (CIP) or Myopathy (CIM) were recruited via personal contact within four weeks (t1) following the transfer from acute care ICU to post-acute ICU at a large rehabilitation hospital. N = 113 (median age 61.1 yrs., 72.6% men) patients were again contacted via telephone three (t2) and six (t3) months following the transfer to post-acute ICU. The MFI-20, the Euro-Quality of Life (EQ-5D-3 L) and the Structured Clinical Interview for the Diagnostic and Statistical Manual of mental disorders DSM-IV (SCID-I) were applied within this prospective cohort study.ResultsThe internal consistency Cronbach’s α was adequate for the MFI-total and all but the subscale Reduced Motivation (RM) (range: .50–.91). Item-to-total correlations (range: .22–.80) indicated item redundancy for the subscale RM. Confirmatory Factor analyses (CFAs) revealed poor model fit for the original 5-factor model of the MFI-20 (t2/t3, Confirmatory Fit Index, CFI = .783/ .834; Tucker-Lewis Index, TLI = .751/ .809; Root Mean Square Error of Approximation, RMSEA = .112/ .103). Among the alternative models (1-, 2-, 3-factor models), the data best fit to a 3-factor solution summarizing the highly correlated factors General −/ Physical Fatigue/ Reduced Activity (GF/ PF/ RA) (t2/ t3, CFI = .878/ .896, TLI = .846/ .869, RMSEA = .089/ .085, 90% Confidence Interval .073–.104/ .066–.104). The MFI-total score significantly correlated with the health-related quality of life (range: −.65-(−).66) and the diagnosis of major depression (range: .27–.37).ConclusionsIn the present sample of CCI patients, a reliable and valid factor structure of the MFI-20 could not be ascertained. Especially the subscale RM should be revised. Since the factors GF, PF and RA cannot be separated from each other and the unclear factorial structure in the present sample of CCI patients, the MFI-20 is not recommended for use in this context.Trial registrationGerman Clinical Trials Registration DRKS00003386.

Benchmarking clinical outcomes and the immunocatabolic phenotype of chronic critical illness after sepsis in surgical intensive care unit patients.

A growing number of patients survive sepsis but remain chronically critically ill. We sought to define clinical outcomes and incidence of chronic critical illness (CCI) after sepsis and to determine whether selected biomarkers of inflammation, immunosuppression, and catabolism differ between these patients and those that rapidly recover (RAP). This 3-year prospective observational cohort study (NCT02276417) evaluated 145 surgical intensive care unit patients with sepsis for the development of CCI (≥14 days of intensive care unit resource utilization with persistent organ dysfunction). Patient clinical demographics, outcomes, and serial serum/urine samples were collected for plasma protein and urinary metabolite analyses. Of 145 sepsis patients enrolled, 19 (13%) died during their hospitalization and 71 (49%) developed CCI. The CCI patients were significantly older (mean, 63 ± 15 vs. 58 ± 13 years, p = 0.006) and more likely to be discharged to long-term acute care facilities (32% vs. 3%, p < 0.0001), whereas those with RAP were more often discharged to home or a rehabilitation facility. Six-month mortality was significantly higher in CCI as compared with RAP cohort (37% vs. 2%; p < 0.01). Multivariate logistic regression modeling revealed delayed onset sepsis (>48 hours after admission; odds ratio [OR], 10.93; 95% confidence interval [CI], 4.15-28.82]), interfacility transfer (OR, 3.58; 95% CI, 1.43-8.96), vasopressor-dependent septic shock (OR, 3.75; 95% CI, 1.47-9.54), and Sequential Organ Failure Assessment score of 5 or greater at 72 hours (OR, 5.03; 95% CI, 2.00-12.62) as independent risk factors for the development of CCI. The CCI patients also demonstrated greater elevations in inflammatory cytokines (IL-6, IL-8, IL-10), and biomarker profiles are consistent with persistent immunosuppression (absolute lymphocyte count and soluble programmed death ligand 1) and catabolism (plasma insulin-like growth factor binding protein 3 and urinary 3-methylhistidine excretion). The development of CCI has become the predominant clinical trajectory in critically ill surgical patients with sepsis. These patients exhibit biomarker profiles consistent with an immunocatabolic phenotype of persistent inflammation, immunosuppression, and catabolism. Prognostic, level II.

The Epidemiology of Chronic Critical Illness After Severe Traumatic Injury at Two Level-One Trauma Centers.

To determine the incidence and risk factors of chronic critical illness after severe blunt trauma. Prospective observational cohort study (NCT01810328). Two level-one trauma centers in the United States. One hundred thirty-five adult blunt trauma patients with hemorrhagic shock who survived beyond 48 hours after injury. None. Chronic critical illness was defined as an ICU stay lasting 14 days or more with evidence of persistent organ dysfunction. Three subjects (2%) died within the first 7 days, 107 (79%) exhibited rapid recovery and 25 (19%) progressed to chronic critical illness. Patients who developed chronic critical illness were older (55 vs 44-year-old; p = 0.01), had more severe shock (base deficit, -9.2 vs -5.5; p = 0.005), greater organ failure severity (Denver multiple organ failure score, 3.5 ± 2.4 vs 0.8 ± 1.1; p < 0.0001) and developed more infectious complications (84% vs 35%; p < 0.0001). Chronic critical illness patients were more likely to be discharged to a long-term care setting (56% vs 34%; p = 0.008) than to a rehabilitation facility/home. At 4 months, chronic critical illness patients had higher mortality (16.0% vs 1.9%; p < 0.05), with survivors scoring lower in general health measures (p < 0.005). Multivariate analysis revealed age greater than or equal to 55 years, systolic hypotension less than or equal to 70 mm Hg, transfusion greater than or equal to 5 units packed red blood cells within 24 hours, and Denver multiple organ failure score at 72 hours as independent predictors of chronic critical illness (area under the receiver operating curve, 0.87; 95% CI, 0.75-0.95). Although early mortality is low after severe trauma, chronic critical illness is a common trajectory in survivors and is associated with poor long-term outcomes. Advancing age, shock severity, and persistent organ dysfunction are predictive of chronic critical illness. Early identification may facilitate targeted interventions to change the trajectory of this morbid phenotype.

"Stuck in the ICU": Caring for Children With Chronic Critical Illness.

Neonatal ICUs and PICUs increasingly admit patients with chronic critical illness: children whose medical complexity leads to recurrent and prolonged ICU hospitalizations. We interviewed participants who routinely care for children with chronic critical illness to describe their experiences with ICU care for pediatric chronic critical illness. Semi-structured interviews. Interviews were transcribed and analyzed for themes. Stakeholders came from five regions (Seattle, WA; Houston, TX; Jackson, MS; Baltimore, MD; and Philadelphia, PA). Fifty-one stakeholders including: 1) interdisciplinary providers (inpatient, outpatient, home care, foster care) with extensive chronic critical illness experience; or 2) parents of children with chronic critical illness. Telephone or in-person interviews. Stakeholders identified several key issues and several themes emerged after qualitative analysis. Issues around chronic critical illness patient factors noted that patients are often relocated to the ICU because of their medical needs. During extended ICU stays, these children require longitudinal relationships and developmental stimulation that outstrip ICU capabilities. Family factors can affect care as prolonged ICU experience leads some to disengage from decision-making. Clinician factors noted that parents of children with chronic critical illness are often experts about their child's disease, shifting the typical ICU clinician-parent relationship. Comprehensive care for children with chronic critical illness can become secondary to needs of acutely ill patients. Lastly, with regard to system factors, stakeholders agreed that achieving consistent ICU care goals is difficult for chronic critical illness patients. ICU care is poorly adapted to pediatric chronic critical illness. Patient, family, clinician, and system factors highlight opportunities for targeted interventions toward improvement in care.

Conversations About Goals and Values Are Feasible and Acceptable in Long-Term Acute Care Hospitals: A Pilot Study.

The chronically critically ill have survived acute critical illness but require prolonged mechanical ventilation. These patients are frequently transferred from acute care to long-term acute care hospitals (LTACHs) for prolonged recovery, yet many suffer setbacks requiring readmission to acute care. The patient's relatively improved condition while at the LTACH might be an opportunity for communication regarding care goals; however, there have been no prior studies of the feasibility of such conversations in the LTACH. To determine the feasibility, acceptability, and potential usefulness of conversations about serious illness with chronic critical illness patients or their surrogate decision makers after LTACH admission. We adapted an existing conversation guide for use in chronically critically ill (defined by tracheotomy for prolonged ventilation) LTACH patients or their surrogates to explore views about quality of life, understanding of medical conditions, expectations, and planning for setbacks. These conversations were conducted by one interviewer and summarized for the patients' clinicians. We surveyed patients, surrogates, and clinicians to assess acceptability. A total of 70 subjects were approached and 50 (71%) were enrolled, including 30 patients and 20 surrogates. The median duration of the conversation was 14 minutes 45 seconds [IQR 12:46, 19]. The presence of ongoing mechanical ventilation did not lead to longer conversations; in fact, conversations with patients were shorter than those with surrogates. The majority of subjects (81%) described the conversation as worthwhile. The majority of clinicians (73%) reported that the conversation offered a new and significant understanding of the patient's preferences if a setback were to occur. Conversations about serious illness care goals can be accomplished in a relatively short period of time, are acceptable to chronically critically ill patients and their surrogate decision makers in the LTACH, and are perceived as worthwhile by patients, surrogates, and clinicians.

“Stuck in the ICU”: Caring for Children with Chronic Critical Illness (S749)

•Describe family factors which contribute to recurrent and prolonged ICU hospitalizations for children with chronic critical illnesses.•Describe clinician factors which contribute to recurrent and prolonged ICU hospitalizations for children with chronic critical illness. Neonatal and pediatric intensive care units (ICU’s) increasingly admit patients with chronic critical illness (CCI)-children whose medical complexity leads to recurrent and prolonged ICU hospitalizations. Describe clinician and family experiences with ICU care for pediatric CCI. Semi-structured interviews with: 1) interdisciplinary providers (inpatient; outpatient; home care; foster care) with extensive CCI experience, or 2) parents of children with CCI. Stakeholders came from 5 regions (Seattle, WA, Houston, TX, Jackson, MS, Baltimore, MD, and Philadelphia, PA). 51 stakeholders identified these ICU challenges for pediatric CCI:•Patient factors Children with CCI are often “stuck” in the ICU because they need therapies (e.g., ventilators) that hospitals centralize to one unit. During extended ICU stays, these children require longitudinal relationships and developmental stimulation that often outstrip ICU staff capabilities. Daily management for pediatric CCI is often dictated by ICU routines; lack of individualized approaches can undermine well-being.•Family factors These families are perceived as particularly vulnerable due to chronic social, emotional, logistical and financial strains. The prolonged ICU experience leads some to disengage from their child and from decision-making.•Clinician factors Clinicians note that parents of children with CCI are often experts about their child’s disease, shifting the typical ICU clinician-parent relationship. Clinicians admit that comprehensive care for children with CCI can become secondary to needs of acutely ill patients. For clinicians, pediatric CCI care is professionally and personally taxing and stretches typical “ICU mentality.”•System factors Stakeholders agree that achieving consistent ICU care goals is difficult for CCI patients. Challenges include rotating ICU staff, an ICU bias toward more interventions, and variability within values-based decision-making. ICU care is poorly adapted to pediatric CCI.

Predictors of posttraumatic stress and quality of life in family members of chronically critically ill patients after intensive care.

Background Prolonged mechanical ventilation for acute medical conditions increases the risk of chronic critical illness (CCI). Close family members are confronted with the life-threatening condition of the CCI patients and are prone to develop posttraumatic stress disorder affecting their health-related quality of life (HRQL). Main aim of the present study was to investigate patient- and family-related risk factors for posttraumatic stress and decreased HRQL in family members of CCI patients.MethodsIn a cross-sectional design nested within a prospective longitudinal cohort study, posttraumatic stress symptoms and quality of life were assessed in family members of CCI patients (n = 83, aged between 18 and 72 years) up to 6 months after transfer from ICU at acute care hospital to post-acute rehabilitation. Patients admitted a large rehabilitation hospital for ventilator weaning. The Posttraumatic Stress Scale-10 and the Euro-Quality of life-5D-3L were applied in both patients and their family members via telephone interview.ResultsA significant proportion of CCI patients and their family members (14.5 and 15.7 %, respectively) showed clinically relevant scores of posttraumatic stress. Both CCI patients and family members reported poorer HRQL than a normative sample. Factors independently associated with posttraumatic stress in family members were the time following ICU discharge (β = .256, 95 % confidence interval .053–.470) and the patients’ diagnosis of PTSD (β = .264, 95 % confidence interval .045–.453). Perceived satisfaction with the relationship turned out to be a protective factor for posttraumatic stress in family members of CCI patients (β = −.231, 95 % confidence interval −.423 to −.015). Regarding HRQL in family members, patients’ acute posttraumatic stress at ICU (β = −.290, 95 % confidence interval −.360 to −.088) and their own posttraumatic stress 3 to 6 months post-transfer (β = −.622, 95 % confidence interval −.640 to −.358) turned out to be significant predictors.ConclusionsPosttraumatic stress and HRQL should be routinely assessed in family members of CCI patients at regular intervals starting early at ICU. Preventive family-centered interventions are needed to improve posttraumatic stress and HRQL in both patients and their family members.Electronic supplementary materialThe online version of this article (doi:10.1186/s13613-016-0174-0) contains supplementary material, which is available to authorized users.

Opinions on the prevention and treatment of chronic critical illness

Chronic critical illness (CCI) is an inevitable result of overpopulation and aging, as well as the development of medicine. The number of CCI patients will constantly increase and become an unaffordable economic burden for families, societies and countries. CCI could be prevented by multiple measures. Firstly, doctors must know about the pathophysiology and etiology of the disease. When providing organ function support for CCI patient, we have to know and treat the cause of the disease as early as possible. Secondly, we need to precisely monitor the insults caused by the disease and/or improper host response to the disease, evaluate the organ reserve function, and predict the outcomes and life quality after discharging from hospital. In addition, it is necessary to strengthen the humanity training of health care workers, publicize the correct thanatopsis in the whole society that every life is "born to die", and define the core role of medicine as "to comfort always".

Persistent inflammation immunosuppression catabolism syndrome: a special type of chronic critical illness

After the concept of "chronic critical illness (CCI)" was proposed, the new concept persistent inflammation immunosuppression catabolism syndrome (PICS) is present recently. Patients with PICS are manifested by fast decreasing body weight, poor nutritional status, long-term immunosuppression and repeated nosocomial infections. These patients are faced with great challenges of persistent inflammation, acquired immunosuppression and high catabolism, which finally results in repeated nosocomial infections, prolonged hospital stay and increased mortality. At present, main problems of PICS diagnosis standard include varying length of ICU stay, difference in normal C reactive protein value, poor value of nutrition indexes, absence of clinical verification. Though associated pathophysiology mechanism is not clear, PICS is preventable and magageable with certain therapy, including early comprehensive prevention and treatment focused on infection control for CCI patients to stop the progression of PICS, application of immune modulator to improve immune function and prognosis of patients, and reasonable nutritional support and treatment. Besides, through the analysis of the association between PICS and CCI, authors draw a conclusion that PICS is a new phenotype of CCI, and immune paralysis is its main feature.

How Long Does (S)He Have? Retrospective Analysis of Outcomes After Palliative Extubation in Elderly, Chronically Critically Ill Patients.

For chronically critically ill elderly patients on mechanical ventilation, prognosis for significant recovery may be minimal. These individuals, or their surrogates, may decide for "palliative extubation." A common prognostic question arises: "How long does she/he have?" This study describes demographics, mortality, time to death, and factors associated with death after palliative extubation. Retrospective 3-year study in community hospital with ethnically diverse elderly population. Chronically critically ill patients followed from palliative extubation to death or survival to discharge. Mortality/survival following palliative extubation, time to death or discharge, factors associated with death. Hundred and forty-eight subjects underwent palliative extubation. Mean age: 78 years, 60% female, ethnically diverse with 46% white, and 54% others. Top diagnostic categories: sepsis (47%) and respiratory failure (22%). After extubation, 114 patients (77%) died in hospital and 34 (23%) were discharged. Of those who died, median time to death 8.9 hours (range, 4 min to 7 d). Mortality proportion was 56% at 24 hours and increased with time. Factors associated with early death: Systolic blood pressure less than 90 (p = 0.002) and Charlson Comorbidity Index that is above 6 or 0 (p = 0.002). Palliative extubation at end of life was an option selected by an ethnically diverse elderly population. Approximately three-fourths of subjects died in hospital, and one-fourth was discharged alive. Over 50% who died did so within 24 hours, making this useful information for counseling and anticipatory planning. Subjects with systolic blood pressure less than 90 and Charlson Comorbidity Index that is very low or very high had higher mortality.

Predictors of Posttraumatic Stress and Quality of Life in Family Members of Chronically Critically ill Patients After Intensive Care

Prolonged mechanical ventilation for acute medical conditions increases the risk of chronic critical illness (CCI). Close family members are confronted with the life-threatening condition of the CCI patients and are prone to develop posttraumatic stress disorder affecting their health-related quality of life (HRQL). Main aim of the present study was to investigate patient- and family-related risk factors for posttraumatic stress and decreased HRQL in family members of CCI patients. In a cross-sectional design nested within a prospective longitudinal cohort study, posttraumatic stress symptoms and quality of life were assessed in family members of CCI patients (n = 83, aged between 18 and 72 years) up to 6 months after transfer from ICU at acute care hospital to post-acute rehabilitation. Patients admitted a large rehabilitation hospital for ventilator weaning. The Posttraumatic Stress Scale-10 and the Euro-Quality of life-5D-3L were applied in both patients and their family members via telephone interview. A significant proportion of CCI patients and their family members (14.5 and 15.7 %, respectively) showed clinically relevant scores of posttraumatic stress. Both CCI patients and family members reported poorer HRQL than a normative sample. Factors independently associated with posttraumatic stress in family members were the time following ICU discharge (β = .256, 95 % confidence interval .053–.470) and the patients’ diagnosis of PTSD (β = .264, 95 % confidence interval .045–.453). Perceived satisfaction with the relationship turned out to be a protective factor for posttraumatic stress in family members of CCI patients (β = −.231, 95 % confidence interval −.423 to −.015). Regarding HRQL in family members, patients’ acute posttraumatic stress at ICU (β = −.290, 95 % confidence interval −.360 to −.088) and their own posttraumatic stress 3 to 6 months post-transfer (β = −.622, 95 % confidence interval −.640 to −.358) turned out to be significant predictors. Posttraumatic stress and HRQL should be routinely assessed in family members of CCI patients at regular intervals starting early at ICU. Preventive family-centered interventions are needed to improve posttraumatic stress and HRQL in both patients and their family members.

Mortality in chronically critically ill patients: Expanding the use of the ProVent score

PurposeThe purpose of the study is to look at the performance of the Prognosis for Prolonged Ventilation (ProVent) score with a short-term outcome as well as when used earlier during the course of prolonged mechanical ventilation (MV). Materials and methodsThis retrospective study was performed in a tertiary public hospital from August 2011 to August 2012. All patients admitted to the intensive care unit (ICU) during this period were included in the study. Chronically critically ill (CCI) patients were defined as those with 21 days of MV. In a subsequent analysis, we considered CCI patients to be those with 14 days of MV. The data were collected in 2 ways: review of a prospectively elaborated database and review of electronic records. ResultsDuring the study period, 1360 patients were admitted to the ICU. Of these, 152 patients (11.2%) were considered CCI. Patients with high ProVent score presented higher ICU mortality. Mortality ranged from 25.0% for patients with a score of 0 to 84.0% for patients with a score of greater than or equal to 4. The analysis of the ProVent score performed earlier during the evolution (14 days of MV) was similar. ConclusionsThe ProVent score can be used for short-term prognosis (mortality in the ICU) and earlier in the evaluation of CCI patients.

Association of Glycemic Control Parameters with Clinical Outcomes in Chronic Critical Illness

Chronic critical illness (CCI) is a term used to designate patients requiring prolonged mechanical ventilation and tracheostomy with associated poor outcomes. The present study assessed the impact of glycemic parameters on outcomes in a CCI population. A retrospective case series was performed including 148 patients in The Mount Sinai Hospital Respiratory Care Unit (2009-2010). Utilizing a semi-parametric mixture model, trajectories for the daily mean blood glucose (BG), BG range, and hypoglycemia rate over time identified low- (n = 87) and high-risk (n = 61) hyperglycemia groups and low- (n = 90) and high-risk (n = 58) hypoglycemia groups. The cohort was also classified into diabetes (DM, n = 48), stress hyperglycemia (SH, n = 85), and normal glucose (n = 15) groups. Hospital- (28% vs. 13%, P = .0199) and 1-year mortality (66% vs. 46%, P = .0185) rates were significantly greater in the high- versus low-risk hyperglycemia groups, respectively. The hypoglycemia rate (<70 mg/dL) was lower among ventilator-liberated patients compared to those who failed to liberate (0.092 vs. 0.130, P<.0001). In the SH group, both hospital mortality (high-risk hyperglycemia 48% and low-risk hyperglycemia 15%, P = .0013) and 1-year mortality (high-risk 74% and low-risk 50%, P = .0482) remained significantly different, while no significant difference in the diabetes group was observed. There were lower hypoglycemia rates with SH compared to diabetes (<70 mg/dL: 0.086 vs. 0.182, P<.0001; <40 mg/dL: 0.012 vs. 0.022, P = .0118, respectively). Tighter glycemic control was associated with improved outcomes in CCI patients with SH but not in CCI patients with diabetes. Confirmation of these findings may lead to stratified glycemic control protocols in CCI patients based on the presence or absence of diabetes.

Chronic Critical Illness: The Growing Challenge to Health Care

The chronically critically ill (CCI) comprise a rapidly growing population of patients who have survived acute critical illness, only to be left with ongoing organ dysfunctions requiring high levels of specialized care for months or years. In many ways, CCI is an "iatrogenic" process, reflecting the ability of modern life support technologies to keep patients alive for prolonged periods of time despite ongoing life threatening illness. Venues of care for the CCI patient include acute care hospitals (both ICU and step-down facilities), specialized long term acute care hospitals, and, less commonly, skilled nursing facilities, or even the home. Importantly, CCI patients transition among these venues frequently, reflecting the nature of CCI to be punctuated with episodes of acute critical illness. Management of the CCI population requires a special combination of intensive care and rehabilitative skills.

Current Venues of Care and Related Costs for the Chronically Critically Ill

The chronically critically ill (CCI) patient population is characterized by a prolonged need for high cost medical interventions, a high 1-year mortality rate, and a very high demand for post acute care services. The best characterized CCI patient population is patients on prolonged mechanical ventilation (PMV). This review will focus on the current knowledge of costs and care venues for the care of this patient population. The PMV population suffers from a prolonged length of acute care hospital stay, median hospital costs 3-4 times the cost of short-term ventilator patients, frequent care venue changes during the course of illness, a small likelihood of discharge to the home environment, yet a hospital mortality that does not differ significantly from the short-term ventilated patient group. The PMV population is projected to double in size by the year 2020. Given the dramatic comparative acute care cost burden of PMV patients, the societal implications for managing both the care burden and the costs of care are staggering. Strategies to improve the efficiency in healthcare for this patient population will be essential. Limitations to the existing care models in the United States will be identified with a focus on our current research deficiencies, which limit healthcare providers and administrators in providing patient focused care for this patient population.

Brain Dysfunction in Patients with Chronic Critical Illness

Critically ill patients frequently experience acute brain dysfunction in the form of coma or delirium, both of which are common during acute and chronic critical illness (CCI). These manifestations of brain dysfunction are associated with numerous adverse outcomes during acute critical illness, including prolonged hospitalization, increased healthcare costs, and increased mortality. The prognosis of CCI patients with coma or delirium has not yet been thoroughly studied, but preliminary studies suggest this population is at high risk for detrimental outcomes associated with acute brain dysfunction. Additionally, a high percentage of patients who survive acute or CCI suffer from long-term brain dysfunction, which manifests primarily as memory deficits and executive dysfunction and is predicted by brain dysfunction in the ICU. Interventions directed at reducing the burden of brain dysfunction during critical illness have shown promise in studies of patients with acute critical illness, but these therapies have yet to be studied during CCI. Thus, multicenter randomized trials are needed to determine which interventions are most effective for such patients. Until these data are available, management strategies that have been proven beneficial during acute critical illness-such as reduction of sedative exposure, especially to benzodiazepines, and early use of physical and occupational therapy-should be employed during the treatment of patients with CCI.
