Brief Summary

The aim of this retrospective observational single-center cohort study is to investigate the factors associated with palliative care (PC) referral, examine intensive care unit (ICU) involvement before, during, or after the referral, and evaluate patient outcomes such as mortality, hospital and ICU length of stay, discharge destination, functional status, symptom management, and the content of PC consultation reports.

Outcome Measures

Primary Outcomes (20)

• Patient demographics

  Demographic information (e.g. age, sex) is collected.

  2019-2024

• Acute prehospital management data

  Data from acute prehospital management, as documented in emergency medical services (EMS) treatment protocols, is collected. The collected data elements are aggregated to describe the overall EMS response.

  2019-2024

• Duration of intensive care unit stay

  The length of intensive care unit (ICU) stay is recorded.

  2019-2024

• Duration of hospital stay

  The length of the total hospital stay is recorded.

  2019-2024

• Discharge destination

  The destination at discharge is recorded.

  2019-2024

• Date of palliative care consult

  The specific date of palliative care consult is documented.

  2019-2024

• Reason for palliative care consult

  The documented reason for palliative care consult is analyzed.

  2019-2024

• Place of palliative care consult

  The specific place of palliative care consult is documented.

  2019-2024

• Number of visits by the palliative care team

  The number of visits by the palliative care team is analyzed.

  2019-2024

• Additional features of the palliative care consult

  Assessment of additional features related to the palliative care consult (changes in management, referral for psychiatric or psychological evaluation, treatment recommendations, etc.) documented in the medical records or consult report. These features are aggregated to characterize the scope, complexity, and potential impact of the palliative care consultation on the patient's overall treatment and care trajectory.

  2019-2024

• Comprehensive assessment of the neurological status based on validated clinical assessment

  Neurological status during ICU stay is assessed using available data in the patient register from validated neurological assessments. These may include the Richmond Agitation-Sedation Scale (RASS), Sedation-Agitation Scale (SAS), Glasgow Coma Scale (GCS), Intensive Care Delirium Screening Checklist (ICDSC), or Status Epilepticus Severity Score (STESS). The specific tool used, as well as the scale of the score and meaning behind the score, depends on routine clinical practice and available documentation in the register. If multiple scores are available for a patient, they will be aggregated to provide a comprehensive assessment of neurological status. This outcome will be reported as a descriptive summary, synthesizing findings across tools, rather than as a single quantitative score.

  2019-2024

• Comprehensive assessment of critical illness severity based on standardized scoring systems

  Disease severity during ICU stay is assessed using standardized scoring systems, including the Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II (SAPS II), and Sequential Organ Failure Assessment (SOFA), depending on data availability in the patient register. The specific scoring system applied, as well as the scale and interpretation of the score, varies based on routine clinical practice and available documentation. Where multiple severity scores are available, they will be synthesized to provide a descriptive summary of overall illness severity rather than a single quantitative score.

  2019-2024

• Charlson Comorbidity Index

  The Charlson Comorbidity Index (CCI) is calculated based on pre-existing comorbidities and additional diagnoses. The CCI predicts the ten-year mortality for a patient who may have a range of comorbid conditions. It assigns weighted scores (from 0 to maximal 6) to 17 comorbid conditions (e.g., heart disease, diabetes, cancer), resulting in a total score ranging from 0 to 33, if the patient had the most severe form of each of the 17 conditions.

  2019-2024

• Laboratory parameters

  Routine laboratory value for e.g. C-Reactive Protein (CRP), albumin, Lactate Dehydrogenase (LDH), Creatine Kinase (CK), procalcitonin, white blood cell levels, creatinine, liver enzymes, blood gas analyses, metabolic data, etc. is collected. The specific parameters recorded may vary depending on the laboratory assessments documented in the patient register. All values will be reported using their respective units of measurement.These parameters are aggregated to support an overall clinical interpretation rather than a single numerical value. This approach reflects standard clinical practice, where multiple lab values are considered together to assess a patient's condition.

  2019-2024

• Complications associated with palliative Care consult

  The complications occurring during or after the palliative care consultation are recorded, including inadequate symptom control, dissatisfaction expressed by the patient or relatives, cardiac arrest, unplanned emergency transfers to the ICU, and poor functional outcomes.

  2019-2024

• Glasgow Outcome Score

  The Glasgow Outcome Score (GOS) is calculated based on the assessment of key clinical outcomes such as inhospital mortality, survival, survival with neurofunctional alteration, return to premorbid neurological function, and hospital readmission to determine the patient outcome. The GOS ranges from 1 (death) to 5 (good recovery).

  2019-2024

• Therapeutic intervention

  The therapeutic intervention is documented, including information on duration, dosage and number of treatment medication, number of neuroleptic, sedative and analgesic drugs, invasive procedures, such as intubation, mechanical, ventilation, vasopressors, installation of central lines, nutrition, etc.

  2019-2024

• Vital signs

  Vital signs are analyzed based on the data available in the patient register. These may include blood pressure, heart rate, respiratory rate, oxygen saturation, body temperature, level of consciousness, etc. The specific parameters recorded depend on the clinical documentation available. All values will be reported using their respective units of measurement. These values are aggregated to support an overall clinical assessment rather than a single numerical score. This reflects standard practice, where multiple vital signs are interpreted together to evaluate a patient's condition.

  2019-2024

• Fluid balance data

  Fluid balance data, including the administration of fluids such as blood products, crystalloids, and enteral/parenteral nutrition, are documented. These components are aggregated to represent overall fluid input for each patient.

  2019-2024

• Assessment of diagnostic procedure

  The diagnostic procedures performed during intensive care-whether invasive (e.g., lumbar puncture, central line placement) or non-invasive (e.g., radiologic imaging, ultrasound)-are systematically documented. Additionally, if physical restraints are used to ensure patient safety or procedural success, their usage are also recorded.
