Fluid management is a critical component in the treatment of patients suffering with major burns. Clinicians must carefully balance judicious resuscitation with the risks of over- or under-resuscitation. We aimed to identify factors associated with survival in burns patients and determine the importance of resuscitation practices.

Unlabelled: Immunosuppression, characterised by impaired immune function, significantly influences infection risk and ICU admissions in critically ill patients. This manuscript highlights the need for grading criteria to assess pre-existing immunosuppression, considering factors like underlying diseases, immunosuppressive therapies, and clinical outcomes variability. We propose a grading system categorising immunosuppression as mild, moderate, or severe.

Background: Platelet transfusions are frequent in the Intensive Care Unit (ICU), either as prophylaxis against bleeding complications or as treatment for bleeding. The European Society of Intensive Care Medicine guidelines for ICU patients generally recommend not using prophylactic platelet transfusions unless the platelet count falls below 10 × 10 cells/L in non-bleeding patients and make no recommendation for platelet transfusion threshold in non-massively bleeding patients with thrombocytopenia. Therefore, the decision to transfuse platelets is often left to clinical assessment by the treating physician.

Background: Patients admitted to intensive care units (ICUs) frequently develop acute kidney injury (AKI). There is limited research comparing outcomes between oliguric and non-oliguric AKI in this population. This study aimed to investigate the short- and long-term outcomes in oliguric and non-oliguric AKI in intensive care patients; the specific outcomes assessed were mortality and major adverse kidney events.

Bayesian analysis is being used with increasing frequency in critical care research and brings advantages and disadvantages compared to traditional Frequentist techniques. This study overviews this methodology and explains the terminology encountered when appraising this literature. Setting different priors can impact the interpretation of new results, and we describe an approach to understanding this.

Background: Platelet transfusions are frequently used in the Intensive Care Unit (ICU) as prophylaxis against bleeding complications. Several guidelines exist on when to administer platelet transfusions in the ICU, but studies indicate that these guidelines are not necessarily followed. The aim of this qualitative study was to understand how experienced ICU physicians make decisions on prescribing prophylactic platelet transfusions and to gain insight into their general concerns and views on blood product transfusions.

Background: Acute kidney injury (AKI) within the intensive care unit (ICU) is common but evidence is limited on longer-term renal outcomes. We aimed to model the trend of kidney function in ICU survivors using estimated glomerular filtration rate (eGFR), comparing those with and without AKI, and investigate potential risk factors associated with eGFR decline.

Methods: This observational cohort study included all patients aged 16 or older admitted to two general adult ICUs in Scotland between 1st July 2015 and 30th June 2018 who survived to 30 days following hospital discharge.

Objective: To determine whether admission to critical care is associated with subsequent disease progression in patients with non-metastatic solid tumors.

Methods: This observational cohort study of UK Biobank participants identified those diagnosed with solid tumors and survived hospitalization. Two cohorts were identified based on critical care admission and new metastatic disease as reported at UK Biobank follow-up visits, or primary or secondary care records were compared.

The European Society of Intensive Care Medicine (ESICM) has developed evidence-based recommendations and expert opinions about end-of-life (EoL) and palliative care for critically ill adults to optimize patient-centered care, improving outcomes of relatives, and supporting intensive care unit (ICU) staff in delivering compassionate and effective EoL and palliative care. An international multi-disciplinary panel of clinical experts, a methodologist, and representatives of patients and families examined key domains, including variability across countries, decision-making, palliative-care integration, communication, family-centered care, and conflict management. Eight evidence-based recommendations (6 of low level of evidence and 2 of high level of evidence) and 19 expert opinions were presented.

Article Synopsis
  • Platelet transfusions are commonly administered in ICUs for patients with low platelet counts (thrombocytopenia), but the specific practices and their outcomes are not well-documented.
  • In a study of 504 ICU patients across Europe and the U.S., 20.8% received platelet transfusions, primarily using pooled products, with varying practices in dosage and volume across different countries.
  • The research found that while platelet transfusions are frequent, they provide limited increases in platelet counts, indicating potential inconsistencies in their effectiveness and administration practices.

Background: Studies suggest increased occurrence of cancer in persons who have experienced a burn injury with hospital admission.

Objective: To determine the incidence of cancer among those hospitalised for burn injuries in Scotland compared with a similar group without a history of burn injury hospitalisation.

Method: A retrospective cohort design was used to compare cancer (ICD10 C00-97, excluding C44) incidence in two groups: 6805 burn injury patients discharged from Scottish hospitals between 2009 and 2019, and 25,946 subjects from the general population who were matched to burn patients by sex, year of birth, and degree of social deprivation.

Article Synopsis
  • Acute kidney injury (AKI) is common in ICU patients and can lead to long-term cardiovascular risks after hospital discharge.
  • A study involving 3994 ICU survivors found that 9.6% experienced major adverse cardiovascular events, with AKI significantly increasing the risk of these events and specifically myocardial injury.
  • The findings suggest that ICU patients with AKI may benefit from better cardiovascular protection strategies, highlighting the need for additional research on this population.

Article Synopsis
  • Thrombocytopenia, defined as a low platelet count, is a frequent issue in ICU patients and is linked to poorer health outcomes, including higher mortality rates.
  • A study involving 1166 ICU patients across 52 ICUs in 10 countries found that 43.2% had thrombocytopenia, with nearly one-quarter presenting with it upon admission.
  • Thrombocytopenia at ICU admission was statistically associated with increased 90-day mortality, and while 22.6% of those affected received platelet transfusions, the majority were given as a precautionary measure.
