AI Article Synopsis
- Patients with critical illnesses often face longer stays in the ICU, resulting in slower recovery and increased long-term health risks, particularly in older or frail individuals.
- This study analyzed data from over 37,000 ICU patients to compare outcomes between those with short (<14 days) and prolonged (≥14 days) ICU stays, identifying key risk factors for sustained critical illness.
- Results showed that patients with prolonged stays were generally younger but more severely ill, facing higher mortality rates in the ICU, hospital, and long-term, emphasizing the need for improved care planning based on these findings.
Article Abstract
Background: Patients with critical illness often survive the intensive care unit (ICU) at a cost of prolonged length of stay (LOS) and slow recovery. This chronic critically ill disease may lead to long-term poor outcomes, especially in older or frail patients.
Objectives: The main goal of this study was to address the characteristics and outcomes of patients with prolonged ICU LOS. Mainly, short- and long-term admissions were compared to identify risk factors for persistent critical illness and to characterise the impact on ICU, hospital, and long-term mortality.
Methods: Subanalysis of a retrospective, multicentric, observational study addressing the 2-year outcome of patients admitted to Portuguese ICUs (the Cimba study). Patients were segregated according to an ICU LOS of ≥14 days.
Results: Data from 37 118 patients were analysed, featuring a median ICU LOS of 4 days (percentile: 25-75 2-9), and a mortality of 16.1% in the ICU, 24.0% in the hospital, and 38.7% after 2 years. A total of 5334 patients (14.4%) had an ICU LOS of ≥14 days (corresponding to 48.9% of all ICU patients/days). Patients with prolonged LOS were more often younger (52.8% vs 46.4%, were ≤65 years of age , p < 0.001), although more severe (Simplified Acute Physiology Score II: 49.1 ± 16.9 vs 41.8 ± 19.5, p < 0.001), and had higher ICU and hospital mortality (18.3% vs 15.7%, and 31.2 vs 22.8%, respectively). Prolonged ICU LOS was linked to an increased risk of dying during the 2-year follow-up (adjusted Cox proportional hazard: 1.65, p < 0.001).
Conclusion: Prolonged LOS is associated with a long-term impact on patient prognosis. More careful planning of care should incorporate these data.

Background And Objectives: This study aimed to investigate the respiratory quotient (RQ) levels and its trend in the early postoperative period of patients with heart disease. Additionally, we explored factors influencing RQ and evaluated the predictive capabilities of RQ and lactic acid for various outcomes.
Methods And Study Design: In this prospective observational study, participants included were heart disease patients aged 18-80 years who underwent elective open-heart surgery and were subsequently admitted to the cardiothoracic surgery ICU post-operation.

Introduction: Critically ill patients and their families benefit from spiritual care. There is limited evidence on how spiritual care is delivered in intensive care units (ICUs).
Aim: The objective of this review was to determine how nurses include spiritual care for patients and families in ICUs.
Study of Children Aged Under 2 Years Admitted With RSV at Four Australian Hospitals [2021-2022].

Aims: Primary aim was to review severe acute respiratory infections (SARI) hospitalisations caused by respiratory syncytial virus (RSV) in children aged < 2 years in paediatric hospitals in Australia. Secondary aims included RSV subtyping, assessing RSV seasonality and contributing to the World Health Organisation's RSV surveillance programme.
Methods: We prospectively reviewed the medical records of children (< 2 years of age) with a confirmed SARI who were admitted to one of four major Australian paediatric hospitals and had a respiratory sample analysed by Polymerase Chain Reaction (PCR).

Introduction: Weight is vital for tracking fluid status and nutrition and assuring patients have accurate dosing weights in the pediatric intensive care unit (PICU). Challenges in acquiring weights in critically ill patients include clinical instability, limited equipment, and lack of appropriate orders in the electronic medical record (EMR).
Methods: We implemented interventions that targeted EMR weight orders and actual collection of weights in the 42-bed PICU of a children's hospital.

Background: Family caregivers of patients with severe acute brain injury (SABI) are at risk for clinically significant chronic emotional distress, including depression, anxiety, and posttraumatic stress. Existing psychosocial interventions for caregivers of intensive care unit (ICU) patients are not tailored to the unique needs of caregivers of patients with SABI, do not demonstrate long-term efficacy, and may increase caregiver burden. In this study, we explored the needs and preferences for psychosocial services among SABI caregivers to inform the development and adaptation of interventions to reduce their emotional distress during and after their relative's ICU admission.
