Predictors of outcomes of patients ≥ 80 years old admitted to intensive care units in Poland - a post-hoc analysis of the VIP2 prospective observational study.

INTRODUCTION: Elderly patients pose a significant challenge to intensive care unit (ICU) clinicians. In this study we attempted to characterise the population of patients over 80 years old admitted to ICUs in Poland and identify associations between clinical features and short-term outcomes. MATERIAL AND METHODS: The study is a post-hoc analysis of the Polish cohort of the VIP2 European prospective observational study enrolling patients > 80 years old admitted to ICUs over a 6-month period. Data including clinical features, clinical frailty scale (CFS), geriatric scales, interventions within the ICU, and outcomes (30-day and ICU mortality and length of stay) were gathered. Univariate analyses comparing frail (CFS > 4) to non-frail patients and survivors to non-survivors were performed. Multivariable models with CFS, activities of daily living score (ADL), and the cognitive decline questionnaire IQCODE as predictors and ICU or 30-day mortality as outcomes were formed. RESULTS: A total of 371 patients from 27 ICUs were enrolled. Frail patients had significantly higher ICU (58% vs. 44.45%, P = 0.03) and 30-day (65.61% vs. 54.14%, P = 0.01) mortality compared to non-frail counterparts. The survivors had significantly lower SOFA score, CFS, ADL, and IQCODE than non-survivors. In multivariable analysis CFS (OR 1.15, 95% CI: 1.00-1.34) and SOFA score (OR 1.29, 95% CI: 1.19-1.41) were identified as significant predictors for ICU mortality; however, CFS was not a predictor for 30-day mortality ( P = 0.07). No statistical significance was found for ADL, IQCODE, polypharmacy, or comorbidities. CONCLUSIONS: We found a positive correlation between CFS and ICU mortality, which might point to the value of assessing the score for every patient admitted to the ICU. The older Polish ICU patients were characterised by higher mortality compared to the other European countries.

Prevalence of life-sustaining treatment limitations in Polish very old intensive care patients (VIPs). A post-hoc analysis of two prospective observational studies.

PURPOSE: Several initiatives have recently focused on raising awareness about limitations of treatment in Poland. We aimed to assess if the propensity to limit LST among elderly patients in 2018-2019 increased compared to 2016-2017. METHODS: We analysed Polish cohorts from studies VIP1 (October 2016 - May 2017) and VIP2 (May 2018 - May 2019) that enrolled critical patients aged >80. We collected data on demographics, clinical features limitations of LST. Primary analysis assessed factors associated with prevalence of limitations of LST, A secondary analysis explored differences between patients with and without limitations of LST. RESULTS: 601 patients were enrolled. Prevalence of LST limitations was 16.1% in 2016-2017 and 20.5% in 2018-2019. No difference was found in univariate analysis (p = 0.22), multivariable model showed higher propensity towards limiting LST in the 2018-2019 cohort compared to 2016-2017 cohort (OR 1.07;95%CI, 1.01-1.14). There was higher mortality and a longer length of stay of patients with limitations of LST compared to the patients without limitations of LST. (11 vs. 6 days, p = 0.001). CONCLUSIONS: The clinicians in Poland have become more proactive in limiting LST in critically ill patients ≥80 years old over the studied period, however the prevalence of limitations of LST in Poland remains low.

Humulus lupus extract rich in xanthohumol improves the clinical course in critically ill COVID-19 patients.

BACKGROUND: The systemic inflammatory response following severe COVID-19 is associated with poor outcomes. Several anti-inflammatory medications have been studied in COVID-19 patients. Xanthohumol (Xn), a natural extract from hop cones, possesses strong anti-inflammatory and antioxidative properties. The aim of this study was to analyze the effect of Xn on the inflammatory response and the clinical outcome of COVID-19 patients. METHODS: Adult patients treated for acute respiratory failure (PaO2/FiO2 less than 150) were studied. Patients were randomized into two groups: Xn - patients receiving adjuvant treatment with Xn at a daily dose of 4.5 mg/kg body weight for 7 days, and C - controls. Observations were performed at four time points: immediately after admission to the ICU and on the 3rd, 5th, and 7th days of treatment. The inflammatory response was assessed based on the plasma IL-6 concentration, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP) and D-dimer levels. The mortality rate was determined 28 days after admission to the ICU. RESULTS: Seventy-two patients were eligible for the study, and 50 were included in the final analysis. The mortality rate was significantly lower and the clinical course was shorter in the Xn group than in the control group (20% vs. 48%, p < 0.05, and 9 ± 3 days vs. 22 ± 8 days, p < 0.001). Treatment with Xn decreased the plasma IL-6 concentration (p < 0.01), D-dimer levels (p < 0.05) and NLR (p < 0.01) more significantly than standard treatment alone. CONCLUSION: Adjuvant therapy with Xn appears to be a promising anti-inflammatory treatment in COVID-19 patients.

Implementation of Computed Tomography Angiography (CTA) and Computed Tomography Perfusion (CTP) in Polish Guidelines for Determination of Cerebral Circulatory Arrest (CCA) during Brain Death/Death by Neurological Criteria (BD/DNC) Diagnosis Procedure.

BACKGROUND: Brain death/death by neurologic criteria (BD/DNC) guidelines are routinely analyzed, compared and updated in the majority of countries and are later implemented as national criteria. At the same time, extensive works have been conducted in order to unify clinical procedures and to validate and implement new technologies into a panel of ancillary tests. Recently evaluated computed tomography angiography and computed tomography perfusion (CTA/CTP) seem to be superior to traditionally used digital subtraction angiography (DSA), transcranial Doppler (TCD) and cerebral perfusion scintigraphy for diagnosis of cerebral circulatory arrest (CCA). In this narrative review, we would like to demonstrate scientific evidence supporting the implementation of CTA/CTP in Polish guidelines for BD/DNC diagnosis. Research and implementation process: In the first of our base studies concerning the potential usefulness of CTA/CTP for the confirmation of CCA during BD/DNC diagnosis procedures, we showed a sensitivity of 96.3% of CTA in a group of 82 patients. CTA was validated against DSA in this report. In the second study, CTA showed a sensitivity of 86% and CTP showed a sensitivity of 100% in a group of 50 patients. In this study, CTA and CTP were validated against clinical diagnosis of BD/DNC supported by TCD. Additionally, we propose our CCA criteria for CTP test, which are based on ascertainment of cerebral blood flow (CBF) < 10 mL/100 g/min and cerebral blood volume < 1 mL/100 g in regions of interest (ROIs) localized in all brain regions. Based on our research results, CTA/CTP methods were implemented in Polish BD/DNC criteria. To our knowledge, CTP was implemented for the first time in national guidelines. CONCLUSIONS: CTA and CTP-derived CTA might be in future the tests of choice for CCA diagnosis, proper and/or Doppler pretest might significantly increase sensitivity of CTA in CCA diagnosis procedures. Whole brain CTP might be decisive in some cases of inconclusive CTA. Implementation of CTA/CTP in the Polish BD/DNC diagnosis guidelines does not show any major obstacles. We believe that in next edition of "The World Brain Death Project" CTA and CTP will be recommended as ancillary tests of choice for CCA confirmation during BD/DNC diagnosis procedures.

An evaluation of the usefulness of extracorporeal liver support techniques in patients with severe liver dysfunction.

INTRODUCTION: The mortality rate in patients with severe liver dysfunction with no option of transplantation is unacceptably high. The main aim of this study was to evaluate the usefulness of applying extracorporeal liver support (ECLS) techniques in this group of patients. MATERIAL AND METHODS: Data from hospital admissions of 101 patients with severe liver dysfunction who were admitted to the department of Anaesthesiology and intensive therapy between 2006 and 2015 were retrospectively analysed. The study group was divided into two subgroups. Standard Medical therapy (SMT) was a subgroup of patients receiving standard Medical therapy, and SMT + ECLS was a subgroup containing patients receiving standard medical therapy complemented by at least one extracorporeal liver support procedure. RESULTS: Significantly lower intensive care unit (ICU) mortality and 30-day mortality rates were found in the SMT + ECLS subgroup (p = 0.0138 and p = 0.0238 respectively). No difference in 3-month mortality was identified between the two groups. In a multivariate model, independent risk factors for ICU mortality proved to be the SOFA score and prothrombin time. The highest discriminatory power for ICU mortality was demonstrated for the SOFA score, followed by APACHE II, SAPS II, MELD UNOS and GCS scores. For 30-day mortality, however, the best discriminatory power was shown for the SAPS II score, followed by SOFA, APACHE II, MELD UNOS and GCS scores. CONCLUSIONS: Further studies are needed to assess the contribution of non-biological extracorporeal liver support procedures to a decrease in mortality rates in the population of patients with severe liver dysfunction.

Frailty is associated with an increased mortality among patients ≥ 80 years old treated in Polish ICUs

BACKGROUND: The increasing population of very old intensive care patients (VIPs) is a major challenge currently faced by clinicians and policymakers. Reliable indicators of VIPs' prognosis and purposefulness of their admission to the intensive care unit (ICU) are urgently needed. METHODS: This is a report from the Polish sample of the VIP1 multicentre cohort study (NCT03134807). Patients ≥ 80 years of age admitted to the ICU were included in the study. Information on the type and reason for admission, demographics, utilisation of ICU procedures, ICU length of stay, organ dysfunction and the decision to apply end-of-life care was collected. The primary objective was to investigate the impact of frailty syndrome on ICU and 30-day survival of VIPs. Frailty was assessed with the Clinical Frailty Scale (≥ 5 points on a scale of 1-9). RESULTS: We enrolled 272 participants with a median age of 84 (81-87) years. Frailty was diagnosed in 170 (62.5%) patients. The ICU and 30-day survival rates were equal to 54.6% and 47.3% respectively. Three variables were found to significantly increase the odds of death in the ICU in a multiple logistic regression model: SOFA score (OR = 1.16; 95%CI 1.16-1.24), acute mode of admission (OR = 5.1; 95%CI 1.67-15.57) and frailty (OR = 2.25; 95%CI 1.26-4.01). CONCLUSION: Measuring frailty in critically ill older adults can facilitate making more informed clinical decisions and help avoid futile interventions.

An Evaluation of the Usefulness of Extracorporeal Liver Support Techniques in Patients Hospitalized in the ICU for Severe Liver Dysfunction Secondary to Alcoholic Liver Disease.

BACKGROUND: The mortality rate in patients with severe liver dysfunction secondary to alcoholic liver disease (ALD) who do not respond to the standard treatment is exceptionally high. OBJECTIVES: The main aim of this study was to evaluate the usefulness of applying extracorporeal liver support techniques to treat this group of patients. PATIENTS AND METHODS: The data from 23 hospital admissions of 21 patients with ALD who were admitted to the department of anesthesiology and intensive therapy (A&IT) at the Dr Wl. Bieganski Regional Specialist Hospital in Lódz between March 2013 and July 2015 were retrospectively analyzed. RESULTS: A total of 111 liver dialysis procedures were performed during the 23 hospitalizations, including 13 dialyses using fractionated plasma separation and adsorption (FPSA) with the Prometheus® system, and 98 procedures using the single pass albumin dialysis (SPAD) system. Upon admission to the intensive care unit (ICU), the median (interquartile range [IQR]) Glasgow coma scale (GCS), sequential organ failure assessment (SOFA), acute physiology and chronic health evaluation (APACHE) II, and simplified acute physiology score (SAPS) II scores were 15 (14 - 15), 9 (7 - 13), 17 (14 - 24), and 32 (22 - 50), respectively. The ICU, 30-day, and three-month mortality rates were 43.48%, 39.13%, and 73.91%, respectively. As determined by the receiver operative characteristic (ROC) analysis for single-factor models, the significant predictors of death in the ICU included the patients' SOFA, APACHE II, SAPS II, and model of end-stage liver disease modified by the united network for organ sharing (MELD UNOS Modification) scores; the duration of stay (in days) in the A&IT Department; and bile acid, creatinine and albumin levels upon ICU admission. The ROC analysis indicated the significant discriminating power of the SOFA, APACHE II, SAPS II, and MELD UNOS modification scores on the three-month mortality rate. CONCLUSIONS: The application of extracorporeal liver support techniques in patients with severe liver dysfunction secondary to ALD appears justified in the subset of patients with MELD UNOS Modification scores of 18 - 30.

Predictive value of the APACHE II, SAPS II, SOFA and GCS scoring systems in patients with severe purulent bacterial meningitis.

BACKGROUND: Scoring systems in critical care patients are essential for predicting of the patient outcome and evaluating the therapy. In this study, we determined the value of the Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II), Sequential Organ Failure Assessment (SOFA) and Glasgow Coma Scale (GCS) scoring systems in the prediction of mortality in adult patients admitted to the intensive care unit (ICU) with severe purulent bacterial meningitis. METHODS: We retrospectively analysed data from 98 adult patients with severe purulent bacterial meningitis who were admitted to the single ICU between March 2006 and September 2015. RESULTS: Univariate logistic regression identified the following risk factors of death in patients with severe purulent bacterial meningitis: APACHE II, SAPS II, SOFA, and GCS scores, and the lengths of ICU stay and hospital stay. The independent risk factors of patient death in multivariate analysis were the SAPS II score, the length of ICU stay and the length of hospital stay. In the prediction of mortality according to the area under the curve, the SAPS II score had the highest accuracy followed by the APACHE II, GCS and SOFA scores. CONCLUSIONS: For the prediction of mortality in a patient with severe purulent bacterial meningitis, SAPS II had the highest accuracy.

Reasons for hospitalisation of HIV-infected patients in ICUs - a single-centre observational study.

BACKGROUND: There are no Polish data regarding the reasons for and incidence of ICU hospitalisations of HIV-infected patients. The aim of the study was to determine the reasons for and incidence of hospitalisations of HIV-infected patients in the Department of Anaesthesiology and Intensive Therapy of the Dr W. Bieganski Regional Specialist Hospital in Lódz in the years 2010-2014. METHODS: Preliminary research enabled to identify all the patients with laboratory-confirmed HIV, including those hospitalised in the ICU. Patients` medical records were analysed. Analysis involved epidemiological data, underlying diagnosis, coexisting diseases and conditions, as well as biochemical, hematologic, virusologic, bacteriologic, mycologic and immunologic tests. RESULTS: In the years 2010-2014, new HIV infections were diagnosed in 224 individuals; 8 of them required ICU hospitalization (10 hospitalisations) - 5 men (62.5%) and 3 women (37.5%). The age of patients ranged from 24 to 46 years. All the patients were diagnosed with AIDS. Three of them died. The patients with HIV constituted 1.30% of all patients hospitalised in the ICU over the period of 5 years. CONCLUSIONS: Low number of HIV-infected patients hospitalised in the ICU in the years 2010-2014 was associated with low HIV incidence rates in the Lódz province and generally available modern antiretroviral therapy rather than restrictive admission policy. Reasons for admission as well as coexisting diseases and conditions, including opportunistic infections, of patients hospitalised in the ICU in 2010-2014 are similar to those in West European countries and the United Stated.

Hepatic encephalopathy in the course of alcoholic liver disease--treatment options in the intensive care unit.

Hepatic encephalopathy occurs as a complication of alcoholic liver disease may require methods of dialysis available in intensive care units. There is described the case of a 27-year-old patient with jaundice and hepatic encephalopathy with long history of alcohol dependence and substance abuse. The patient was successfully treated using liver dialysis method (Prometheus® system). Basing on this case it is possible to conclude that use of dialysis liver with Prometheus® may be beneficial in patients with severe course of alcoholic liver disease.

Rationale of statin therapy in septic patients.

Statins are well-established and effective drugs in the treatment of hyperlipidemias. However the effects of statins extend beyond lipid-lowering. The pleiotropic effects of statins have been shown to modify inflammatory cell signaling of the immune response to infection. Statins have emerged as potential immunomodulatory and antioxidant agents that might impact on sepsis outcomes. It was postulated that statins may be candidates for the treatment of sepsis. Recent animal and human data suggest that statin therapy might be beneficial in patients before the onset of sepsis or in its initial period, but should be used with care when patients are diagnosed with severe sepsis or septic shock. Some analyses also provide evidence for statins as an adjuvant therapy in sepsis. Because of the divergent results of studies, the potential benefit needs to be validated in randomized, controlled trials. In this review, we describe current evidence on the use of statins in the prevention and treatment of sepsis.

Adult intensive therapy services contracted by the National Health Fund in 2012.

BACKGROUND: Limited financial resources of the National Health Fund (NHF) affect the extent of funding allocated for intensive therapy services. The objective of the study was to analyse the levels of funding the departments of anaesthesiology and intensive therapy are provided with by NHF regional branches in 2012. METHODS: Websites of NHF regional branches were surveyed to obtain the data about the therapeutic entities containing departments of anaesthesiology and intensive therapy, whose services were contracted by NHF in 2012. The contract value, number of contracted points and price of a point were determined for each department. Moreover, based on preliminary survey of the National Official Register of Economic Entities (REGON), the number of intensive therapy beds in the departments in question was calculated. RESULTS: The highest expenditure on adult intensive therapy per one citizen was found in the West Pomeranian, Podlasie and Lesser Poland provinces whereas the lowest one in Swietokrzyskie, Pomeranian and Lublin provinces. CONCLUSION: Funds allocated by NHF for services of departments of anaesthesiology and intensive therapy are insufficient.

Paediatric intensive therapy services contracted by the National Health Fund in 2012.

BACKGROUND: Departments of paediatric anaesthesiology and intensive therapy are relevant elements of the healthcare system in Poland. The aim of the present study was to analyse the level of funding of departments of paediatric anaesthesiology and intensive therapy provided by regional branches of the National Health Fund (NHF) in 2012. METHODS: The survey of websites of regional branches of NHF provided data about therapeutic entities with departments of paediatric anaesthesiology and intensive therapy, whose services were contracted by NHF in 2012. The contract value for 2012, number of contracted points and price of a point were defined for each department. Moreover, using the Register of Therapeutic Entities, the number of intensive therapy beds in the departments of paediatric anaesthesiology and intensive therapy in these entities was determined. RESULTS: The highest expenditure for intensive therapy of children and teenagers under 17 years of age per one citizen was found in the Silesian, Opole and Lodz provinces; the lowest expenditure was observed in the Lubusz (no contracted departments), Swietokrzyskie and Podkarpacie provinces. CONCLUSION: The level of funding of departments of paediatric anaesthesiology and intensive therapy provided by NHF appears to be sufficient; however, the staff and equipment potential of many such departments is not fully exploited.

Risk management in intensive therapy units - the method of determination of black spots.

BACKGROUND: Patients hospitalised in intensive care units are more likely to suffer an adverse event than those treated in other hospital wards. The aim of this study was to assess the usefulness of identifying the events (the so-called 'black spots') that constitute a significant threat to life and health of patients and/or financing of the hospital. METHODS: We retrospectively analysed 30 medical records and other documents relating to the stay of patients hospitalised in the Department of Anaesthesiology and Intensive Care at the Regional Hospital in Swidnica in 2010. To determine the 'black spots', the authors used their own methods. RESULTS: We identified 31 adverse events (12 types of events) that occurred during the provision of healthcare in the intensive care unit. Six black spots were determined based on the model adopted in the study. CONCLUSIONS: Identifying black spots can help to substantially reduce morbidity and mortality in hospitalised patients. It also allows optimisation of therapeutic entities, particularly in intensive care units.
