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.

[Acute poisonings with carbon monoxide among the patients hospitalized in the Toxicology Unit during the period of 2006-2010]. / Zatrucia tlenkiem wegla w materiale Oddzialu Toksykologii Instytutu Medycyny Pracy w Lodzi w latach 2006-2010.

Acute poisonings with carbon monoxide pose real challenge in the clinical toxicology. Its importance is determined both by high frequency of immediate life threatening conditions and by the risk of complications leading to permanent organs damage. The main objective of this study is an identification of prognostic factors on the base of analysis the cohort of patients hospitalized due to intoxication with these agents in the Toxicology Unit during the period 2006-2010. During the search process 571 patients hospitalized due to carbon monoxide poisoning during the period 2006-2010 were identified within total number of 21 400 subjects hospitalized during studied period. Therefore intoxications with carbon monoxide accounted for 2.66% of total admissions to the unit. The main sources of exposure were faulty gas heaters. Patients condition on admission varied, with most cases described as the moderate and severe state. At the moment of admission to hospital, the most frequently noted pathologies were: vertigo, headeache and complains from the respiratory tract. The most commonly encountered complication were labyrinths' injuries, neurological abnormalities and pneumonia. Mean concentration of COHb measured on admission in this group was in the blood 21.50 +/- 10.96%. Poor prognosis may be associated with such clinical features on admission, as: respiratory and circulatory disturbances, cerebral sequelae and reported sequelae from labyrinths. Such parameters as: COHb level, lactate and troponine concentrations and BE values measured on admission should be considered as the prognostic factors, determining the course of the disease and the outcomes of treatment.

[Suicidal intoxication with digoxin--still actual problem in clinical toxicology--case report]. / Samobójcze zatrucie digoksyna--nadal aktualny problem toksykologii klinicznej --opis przypadku.

We present case a male patient who attempted suicide by ingestion of 90 tablets of digoxin in total dose of 22.5 mg. A measured peak level of digoxin was 6,75 ng/ml. Temporary invasive cardiac pacing with single chamber ventricular pacer was performed for treatment of the life-threatening rhythm and conduction disturbances that revealed within few hours after admission. According to the authors, presented method of therapy should always be taken into consideration in case development of cardiovascular disturbances in acute poisoning with digoxin.

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.

[Is it possible to predict the success of pharmacological closure of persistent ductus arteriosus in prematurely born neonates?]. / Czy mozna przewidziec skutecznosc farmakoterapii przetrwalego przewodu tetniczego u przedwczesnie urodzonych noworodków?

BACKGROUND: Haemodynamically significant persistent ductus arteriosus (PDA) with left-to-right shunting causes overload of the pulmonary circulation and results in prolonged mechanical ventilation and oxygen dependence. Among other options, pharmacological closure using cyclooxygenase inhibitors remains popular among neonatologists. The purpose of the study was to assess the importance of factors affecting the outcome of the aforementioned strategy. METHODS: Charts of neonates with respiratory failure treated with indomethacin for PDA were retrospectively analyzed. Patients with other heart abnormalities and those with delayed PDA therapy were excluded. RESULTS: 83 patients met the inclusion criteria. The median birth weight was 1000 g (interquartile range--IQR 800-1320), and gestational age was 27 weeks (IQR 26-30). The overall success rate of primary treatment with indomethacin was 57%. Surgical PDA ligation was performed in 32%. Factors which contributed significantly (p < 0.05) to the failure of indomethacin treatment were: each 10 mL kg(-1) of intravenous fluid administration that exceeded the total amount of 100 mL kg(-1) 24h(-1), odds ratio (OR) 1.12; a PDA diameter/body mass index (OR 1.93); and gestational age (OR 0.78). In a multivariate model, the following factors were found significant: gestational age OR 0.76 (95% confidence interval 0.61-0.95) and i.v. fluid excess OR 1.14 (95% CI 1.02-1.27). In patients with primary treatment failure a higher incidence of bronchopulmonary dysplasia (BPD) (67% vs. 36% p = 0.006), and combined BPD or death (72% vs 42.5% p = 0.01) were noted. CONCLUSIONS: Prediction of successful treatment with indomethacin is possible on the basis of gestational age and daily fluid intake. These factors should be considered when considering the risk/benefit of indomethacin therapy.

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.

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.
