- Background Few studies have examined survival in intensive care unit (ICU) patients after the restriction of life-sustaining treatment (LST). We aimed to analyse independent factors associated with hospital and 12-month survival rates in ICU patients after treatment restrictions. Methods This retrospective observational study examined all patients treated in adult ICUs from 1 January 2016 until 31 December 2016 included in the Finnish ICU Registry. Multivariable logistic regression analysis was performed to explain the effect on survival. Results Decisions to limit LST were made for 2444 patients (13.7%; 95% CI 13.2-14.2). ICU, hospital, and 12-month survival rates were 71% (95% CI 69-73), 49% (95% CI 47-51), and 24% (95% CI 22-26), respectively. In patients for whom life support was withheld, increased 12-month survival rates were associated with admission from the operating theatre (OR 1.9, 95% CI 1.1-3.4), good pre-hospital physical fitness (OR 4.7, 95% Cl 1.2-16.8) and being housed at home (OR 2.0, 95% Cl 1.4-2.8). Decreased survival rates were associated with admission from a hospital ward (OR 0.67, 95% Cl 0.5-0.9), higher comorbidity (OR 0.6, 95% Cl 0.4-0.9), cancer (OR 0.4, 95%CI 0.2-0.9), greater illness severity (SAPS II; OR 0.98, 95% Cl 0.98-0.99), and higher care intensity (TISS-76; OR 0.93, 95% Cl 0.92-0.95). Conclusion Survival among ICU patients with limited treatment was higher than expected. Advanced age was not associated with higher mortality, potentially because treatment restrictions may be set more easily for older patients.

- Background Few studies have examined the factors that predict the limitations of life-sustaining treatment (LST) to patients in intensive care units (ICUs). We aimed to identify variables associated with the decision of withholding of life support (WHLS) at admission, WHLS during ICU stay and the withdrawal of ongoing life support (WDLS). Methods This retrospective observational study comprised 17,772 adult ICU patients who were included in the nationwide Finnish ICU Registry in 2016. Factors associated with LST limitations were identified using hierarchical logistic regression. Results The decision of WHLS at admission was made for 822 (4.6%) patients, WHLS during ICU stay for 949 (5.3%) patients, and WDLS for 669 (3.8%) patients. Factors strongly predicting WHLS at admission included old age (adjusted odds ratio [OR] for patients aged 90 years or older in reference to those younger than 40 years was 95.6; 95% confidence interval [CI], 47.2-193.5), dependence on help for activities of daily living (OR, 3.55; 95% CI, 3.01-4.2), and metastatic cancer (OR, 4.34; 95% CI, 3.16-5.95). A high severity of illness predicted later decisions to limit LST. Diagnoses strongly associated with WHLS at admission were cardiac arrest, hepatic failure and chronic obstructive pulmonary disease. Later decisions were strongly associated with cardiac arrest, hepatic failure, non-traumatic intracranial hemorrhage, head trauma and stroke. Conclusion Early decisions to limit LST were typically associated with old age and chronic poor health whereas later decisions were related to the severity of illness. Limitations are common for certain diagnoses, particularly cardiac arrest and hepatic failure.

Tidskriftsartikel (refereegranskat)abstract
- Background We sought to provide a description of surge response strategies and characteristics, clinical management and outcomes of patients with severe COVID-19 in the intensive care unit (ICU) during the first wave of the pandemic in Denmark, Finland, Iceland, Norway and Sweden. Methods Representatives from the national ICU registries for each of the five countries provided clinical data and a description of the strategies to allocate ICU resources and increase the ICU capacity during the pandemic. All adult patients admitted to the ICU for COVID-19 disease during the first wave of COVID-19 were included. The clinical characteristics, ICU management and outcomes of individual countries were described with descriptive statistics. Results Most countries more than doubled their ICU capacity during the pandemic. For patients positive for SARS-CoV-2, the ratio of requiring ICU admission for COVID-19 varied substantially (1.6%-6.7%). Apart from age (proportion of patients aged 65 years or over between 29% and 62%), baseline characteristics, chronic comorbidity burden and acute presentations of COVID-19 disease were similar among the five countries. While utilization of invasive mechanical ventilation was high (59%-85%) in all countries, the proportion of patients receiving renal replacement therapy (7%-26%) and various experimental therapies for COVID-19 disease varied substantially (e.g. use of hydroxychloroquine 0%-85%). Crude ICU mortality ranged from 11% to 33%. Conclusion There was substantial variability in the critical care response in Nordic ICUs to the first wave of COVID-19 pandemic, including usage of experimental medications. While ICU mortality was low in all countries, the observed variability warrants further attention.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To determine the ability of serum glial fibrillary acidic protein (GFAp) and tau protein to predict neurological outcome after out-of-hospital cardiac arrest (OHCA). Methods: We measured plasma concentrations of GFAp and tau of patients included in the previously published COMACARE trial (NCT02698917) on intensive care unit admission and at 24, 48, and 72 h after OHCA, and compared them to neuron specific enolase (NSE). NSE concentrations were determined already during the original trial. We defined unfavourable outcome as a cerebral performance category (CPC) score of 3–5 six months after OHCA. We determined the prognostic accuracy of GFAp and tau using the receiver operating characteristic curve and area under the curve (AUROC). Results: Overall, 39/112 (35%) patients had unfavourable outcomes. Over time, both markers were evidently higher in the unfavourable outcome group (p < 0.001). At 48 h, the median (interquartile range) GFAp concentration was 1514 (886–4995) in the unfavourable versus 238 (135–463) pg/ml in the favourable outcome group (p < 0.001). The corresponding tau concentrations were 99.6 (14.5–352) and 3.0 (2.2–4.8) pg/ml (p < 0.001). AUROCs at 48 and 72 h were 0.91 (95% confidence interval 0.85–0.97) and 0.91 (0.85–0.96) for GFAp and 0.93 (0.86–0.99) and 0.95 (0.89–1.00) for tau. Corresponding AUROCs for NSE were 0.86 (0.79–0.94) and 0.90 (0.82–0.97). The difference between the prognostic accuracies of GFAp or tau and NSE were not statistically significant. Conclusions: At 48 and 72 h, serum both GFAp and tau demonstrated excellent accuracy in predicting outcomes after OHCA but were not superior to NSE. Clinical trial registration: NCT02698917 (https://www.clinicaltrials.gov/ct2/show/NCT02698917).

Higher versus lower blood pressure targets after cardiac arrest : Systematic review with individual patient data meta-analysis
- 2023

Forskningsöversikt (refereegranskat)abstract
- Purpose: Guidelines recommend targeting mean arterial pressure (MAP) > 65 mmHg in patients after cardiac arrest (CA). Recent trials have studied the effects of targeting a higher MAP as compared to a lower MAP after CA. We performed a systematic review and individual patient data meta-analysis to investigate the effects of higher versus lower MAP targets on patient outcome. Method: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, LILACS, BIOSIS, CINAHL, Scopus, the Web of Science Core Collection, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry, Google Scholar and the Turning Research into Practice database to identify trials randomizing patients to higher (≥71 mmHg) or lower (≤70 mmHg) MAP targets after CA and resuscitation. We used the Cochrane Risk of Bias tool, version 2 (RoB 2) to assess for risk of bias. The primary outcomes were 180-day all-cause mortality and poor neurologic recovery defined by a modified Rankin score of 4–6 or a cerebral performance category score of 3–5. Results: Four eligible clinical trials were identified, randomizing a total of 1,087 patients. All the included trials were assessed as having a low risk for bias. The risk ratio (RR) with 95% confidence interval for 180-day all-cause mortality for a higher versus a lower MAP target was 1.08 (0.92–1.26) and for poor neurologic recovery 1.01 (0.86–1.19). Trial sequential analysis showed that a 25% or higher treatment effect, i.e., RR < 0.75, can be excluded. No difference in serious adverse events was found between the higher and lower MAP groups. Conclusions: Targeting a higher MAP compared to a lower MAP is unlikely to reduce mortality or improve neurologic recovery after CA. Only a large treatment effect above 25% (RR < 0.75) could be excluded, and future studies are needed to investigate if relevant but lower treatment effect exists. Targeting a higher MAP was not associated with any increase in adverse effects.

- PURPOSEWe aimed to determine the incidence, risk factors and outcome of acute kidney injury (AKI) in Finnish ICUs.METHODSThis prospective, observational, multi-centre study comprised adult emergency admissions and elective patients whose stay exceeded 24 h during a 5-month period in 17 Finnish ICUs. We defined AKI first by the Acute Kidney Injury Network (AKIN) criteria supplemented with a baseline creatinine and second with the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. We screened the patients' AKI status and risk factors for up to 5 days.RESULTSWe included 2,901 patients. The incidence (95 % confidence interval) of AKI was 39.3 % (37.5-41.1 %). The incidence was 17.2 % (15.8-18.6 %) for stage 1, 8.0 % (7.0-9.0 %) for stage 2 and 14.1 % (12.8-15.4 %) for stage 3 AKI. Of the 2,901 patients 296 [10.2 % (9.1-11.3 %)] received renal replacement therapy. We received an identical classification with the new KDIGO criteria. The population-based incidence (95 % CI) of ICU-treated AKI was 746 (717-774) per million population per year (reference population: 3,671,143, i.e. 85 % of the Finnish adult population). In logistic regression, pre-ICU hypovolaemia, diuretics, colloids and chronic kidney disease were independent risk factors for AKI. Hospital mortality (95 % CI) for AKI patients was 25.6 % (23.0-28.2 %) and the 90-day mortality for AKI patients was 33.7 % (30.9-36.5 %). All AKIN stages were independently associated with 90-day mortality.CONCLUSIONSThe incidence of AKI in the critically ill in Finland was comparable to previous large multi-centre ICU studies. Hospital mortality (26 %) in AKI patients appeared comparable to or lower than in other studies.

Tidskriftsartikel (refereegranskat)abstract
- Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventions on outcomes for the future 2×2×2 factorial designed randomised clinical Sedation, TEmperature, and Pressure after Cardiac Arrest and REsuscitation (STEPCARE) trial in comatose patients after out-of-hospital cardiac arrest. Methods: By simulating a multisite trial with 50 sites and 3278 participants, and a presumed six-month all-cause mortality of 60% in the control population, we will investigate the validity of the trial results with different levels of interaction effects on the outcome. The primary simulation outcome of the study is the risks of type-1 and type-2 errors in the simulated scenarios, i.e. at what level of interaction is the desired alpha and beta level exceeded. When keeping the overall risk of type-1 errors ≤ 5% and the risk of type-2 errors ≤ 10%, we will quantify the maximum interaction effect we can accept if the planned sample size is increased by 5% to take into account possible interaction between the trial interventions. Secondly, we will assess how interaction effects influence the minimal detectable difference we may confirm or reject to take into account 5% (small interaction effect), 10% (moderate), or 15% (large) positive interactions in simulations with no ‘true’ intervention effect (type-1 errors) and small (5%), moderate (10%), or large negative interactions (15%) in simulations with ‘true’ intervention effects (type-2 errors). Moreover, we will investigate how much the sample size must be increased to account for a small, moderate, or large interaction effects. Discussion: This protocol for a simulation study will inform the design of a 2×2×2 factorial randomised clinical trial of how potential interactions between the assessed interventions might affect conclusions. Protocolising this simulation study is important to ensure valid and unbiased results.

Tidskriftsartikel (refereegranskat)abstract
- Background: Hypotension is common after cardiac arrest (CA), and current guidelines recommend using vasopressors to target mean arterial blood pressure (MAP) higher than 65 mmHg. Pilot trials have compared higher and lower MAP targets. We will review the evidence on whether higher MAP improves outcome after cardiac arrest. Methods: This systematic review and meta-analysis will be conducted based on a systematic search of relevant major medical databases from their inception onwards, including MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as clinical trial registries. We will identify randomised controlled trials published in the English language that compare targeting a MAP higher than 65–70 mmHg in CA patients using vasopressors, inotropes and intravenous fluids. The data extraction will be performed separately by two authors (a third author will be involved in case of disagreement), followed by a bias assessment with the Cochrane Risk of Bias tool using an eight-step procedure for assessing if thresholds for clinical significance are crossed. The outcomes will be all-cause mortality, functional long-term outcomes and serious adverse events. We will contact the authors of the identified trials to request individual anonymised patient data to enable individual patient data meta-analysis, aggregate data meta-analyses, trial sequential analyses and multivariable regression, controlling for baseline characteristics. The certainty of the evidence will be assessed by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. We will register this systematic review with Prospero and aim to redo it when larger trials are published in the near future. Conclusions: This protocol defines the performance of a systematic review on whether a higher MAP after cardiac arrest improves patient outcome. Repeating this systematic review including more data likely will allow for more certainty regarding the effect of the intervention and possible sub-groups differences.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The length of stay (LOS) in intensive care unit (ICU) nonsurvivors is not often reported, but represents an important indicator of the use of resources. LOS in ICU nonsurvivors may also be a marker of cultural and organizational differences between units. In this study based on the national intensive care registries in Finland, Sweden, and Norway, we aimed to report intensive care mortality and to document resource use as measured by LOS in ICU nonsurvivors. Methods: Registry data from 53,305 ICU patients in 2006 were merged into a single database. ICU nonsurvivors were analyzed with regard to LOS within subgroups by univariate and multivariate analysis (Cox proportional hazards regression). Results: Vital status at ICU discharge was available for 52,255 patients. Overall ICU mortality was 9.1%. Median LOS of the nonsurvivors was 1.3 days in Finland and Sweden, and 1.9 days in Norway. The shortest LOS of the nonsurvivors was found in patients older than 80 years, emergency medical admissions, and the patients with the highest severity of illness. Multivariate analysis confirmed the longer LOS in Norway when corrected for age group, admission category, sex, and type of hospital. LOS in nonsurvivors was found to be inversely related to the severity of illness, as measured by APACHE II and SAPS II. Conclusions: Despite cultural, religious, and educational similarities, significant variations occur in the LOS of ICU nonsurvivors among Finland, Norway, and Sweden. Overall, ICU mortality is low in the Scandinavian countries.
