RESUMEN
BACKGROUND: Following critical illness, family members are often required to adopt caregiving responsibilities. Anxiety and depression are common long term problems for both patients and caregivers. However, at present, it is not known how the trajectories of these symptoms compare between patients and caregivers. OBJECTIVES: The aim of this study was to investigate and compare the trajectories of anxiety and depression in patients and caregivers in the first year following critical illness. METHODS: This study analyses data from a prospective multicentre cohort study of patients and caregivers who underwent a complex recovery intervention following critical illness. Paired patients and caregivers were recruited. The Hospital Anxiety and Depression Scale was used to evaluate symptoms of anxiety and depression at three timepoints: baseline; 3 months; and 12 months in both patient and caregivers. A linear mixed-effects regression model was used to evaluate the trajectories of these symptoms over the first year following critical illness. RESULTS: 115 paired patients and caregivers, who received the complex recovery intervention, were recruited. There was no significant difference in the relative trajectory of depressive symptoms between patients and caregivers in the first 12 months following critical illness (p = 0.08). There was, however, a significant difference in the trajectory of anxiety symptoms between patients and caregivers during this time period (p = 0.04), with caregivers seeing reduced resolution of symptoms in comparison to patients. CONCLUSIONS: Following critical illness, symptoms of anxiety and depression are common in both patients and caregivers. The trajectory of symptoms of depression was similar between caregivers and patients; however, there was a significantly different recovery trajectory in symptoms of anxiety. Further research is required to understand the recovery pathway of caregivers in order to design effective interventions.
RESUMEN
Background: Sepsis is one of the most common reasons for ICU admission and a leading cause of mortality worldwide. More than one-half of survivors experience significant physical, psychological, or cognitive impairments, often termed post-intensive care syndrome (PICS). Sepsis is recognized increasingly as being associated with a risk of adverse cardiovascular events that is comparable with other major cardiovascular risk factors. It is plausible that sepsis survivors may be at risk of unidentified cardiovascular disease, and this may play a role in functional impairments seen after ICU discharge. Research Question: What is the prevalence of myocardial dysfunction after an ICU admission with sepsis and to what extent might it be associated with physical impairments in PICS? Study Design and Methods: Characterisation of Cardiovascular Function in ICU Survivors of Sepsis (CONDUCT-ICU) is a prospective, multicenter, pilot study characterizing cardiovascular function and functional impairments in survivors of sepsis taking place in the west of Scotland. Survivors of sepsis will be recruited at ICU discharge and followed up 6 to 10 weeks after hospital discharge. Biomarkers of myocardial injury or dysfunction (high sensitivity troponin and N-terminal pro B-type natriuretic peptide) and systemic inflammation (C-reactive protein, IL-1ß, IL-6, IL-10, and tumor necrosis factor alpha) will be measured in 69 patients at recruitment and at follow-up. In addition, a cardiovascular magnetic resonance substudy will be performed at follow-up in 35 patients. We will explore associations between cardiovascular magenetic resonance indexes of cardiac function, biomarkers of cardiac dysfunction and inflammation, and patient-reported outcome measures. Interpretation: CONDUCT-ICU will provide data regarding the cause and prevalence of cardiac dysfunction in survivors of sepsis and will explore associations with functional impairment. It will provide feasibility data and operational learning for larger studies investigating mechanisms of functional impairment after ICU admission and the association between sepsis and adverse cardiovascular events.

RESUMEN
PURPOSE: Survivors of critical illness frequently experience long-term symptoms including physical symptoms such as pain and emotional symptoms such as anxiety and depression. These symptoms frequently co-exist, however, at present there is limited understanding of these relationships. The aim of this study was to quantify the relationship between pain, anxiety and depression across the recovery trajectory. METHODS: This study is a secondary analysis of data from a multi-centre, prospective, cohort study which followed-up patients recovering from critical illness. Data was available at multiple time points and for 3 distinct cohorts. Structural equation modelling was used to investigate the relationship between outcome measures of pain, anxiety and depression. RESULTS: Data from 414 patients was analysed. Pain was significantly associated with both anxiety and depression in all cohorts and at all time points sampled. Path coefficients for the covariances between pain and depression ranged between 0.39 and 0.72 (p < 0.01). Path coefficients for the covariances between pain and anxiety ranged between 0.39 and 0.65 (p < 0.01). CONCLUSIONS: Pain, anxiety and depression are highly correlated in survivors of critical illness. Pharmacological treatments for pain management may be ineffective alone and further research is required to assess interventions targeting these symptoms in combination.

INTRODUCTION: Pain is a common and debilitating symptom in survivors of critical illness. The 'Core Outcome Set for Survivors of Acute Respiratory Failure' proposes that the pain and discomfort question of the EuroQol 5 Dimension 5 Level (EQ-5D-5L) could be used to assess pain in this group, however, it was recognised that further research is required to evaluate how this single question compares to other more detailed pain tools. This study aims to evaluate the relationship between the pain and discomfort question of the EQ-5D-5L and the Brief Pain Inventory (BPI) in survivors of critical illness. METHODS: This study retrospectively analysed paired EQ-5D-5L and BPI data extracted from a prospective, multicentre study evaluating the impact of a critical care recovery programme. 172 patients who received a complex recovery intervention and 108 patients who did not receive this intervention were included. Data were available for the intervention cohort at multiple time points, namely, baseline, 3 months and 12 months. While, data were available for the usual care cohort at a single time point (12 months). We assessed the correlation between the pain and discomfort question of the EQ-5D-5L and two separate components of the BPI: severity of pain and pain interference. RESULTS: Correlation coefficients comparing the pain and discomfort question of the EQ-5D-5L and the BPI pain severity score ranged between 0.73 (95% CI 0.63 to 0.80) and 0.80 (95% CI 0.72 to 0.86). Correlation coefficients comparing the pain and discomfort question of the EQ-5D-5L and the BPI pain interference score ranged between 0.71 (95% CI 0.62 to 0.79) and 0.83 (95% CI 0.76 to 0.88) across the various time points. CONCLUSIONS: The pain and discomfort question of the EQ-5D-5L correlates moderately well with a more detailed pain tool and may help to streamline assessments in survivorship studies. More in-depth tools may be of use where pain is the primary study outcome or a patient-reported concern.
