Emotional distress in neuro-ICU survivor-caregiver dyads: The recovering together randomized clinical trial

How and when post intensive care syndrome-family is measured: A scoping review

OBJECTIVES

Family members of Intensive Care Unit (ICU) patients can experience mental health difficulties. These are collectively described as Post Intensive Care Syndrome-Family (PICS-F). There are no standardised outcome measures to benchmark the impact of PICS-F. This scoping review aimed to map and characterise interventions, outcomes, and outcome instruments related to PICS-F.

METHODS

Eight databases were searched in June 2023: Pubmed, CINAHL, Ovid Medline, EMBASE, PsycInfo, AMED, Emcare and Cochrane. The grey literature was also searched. Studies published after 2012 related to PICS-F were included. Search strategy included: (Population) family members of adult ICU patients, (Concept) PICS-F, (Context) ICU settings. Frequency analysis of outcomes was performed, and instruments were mapped to describe the characteristics.

RESULTS

Of the identified 4848 records, 46 papers representing 44 unique studies met the inclusion criteria and were retained for analysis. In total, 8008 family members were represented across 15 countries in four continents worldwide. The number of studies reporting PICS-F interventions increased rapidly over the past 12 years and were performed in ICUs treating mixed conditions. Studies were randomised control trials (n = 33), before-and-after design (n = 6) and non-randomised trials (n = 5). A total of 18 outcome instruments were used measuring predominantly anxiety, with complicated grief measured only once. The identified instruments were mostly validated for clinical and disease specific populations but not validated among relatives of ICU patients.

CONCLUSION

There is a plethora of instruments measuring PICS-F outcomes. No core outcome set is currently available for PICS-F. To reduce heterogeneity of how PICS-F is measured, a core outcome set with validated measurements is recommended to allow benchmarking and to document the impact of PICS-F interventions.

IMPLICATIONS FOR CLINICAL PRACTICE

Recognising PICS-F symptoms and understanding how to assess them could help clinicians to develop interventions to improve family outcomes. Validated instruments are needed to evaluate these interventions.

Survivorship After Neurocritical Care: A Scoping Review of Outcomes Beyond Physical Status

Following intensive care unit hospitalization, survivors of acute neurological injury often experience debilitating short-term and long-term impairments. Although the physical/motor impairments experienced by survivors of acute neurological injury have been described extensively, fewer studies have examined cognitive, mental health, health-related quality of life (HRQoL), and employment outcomes. This scoping review describes the publication landscape beyond physical and/or motor sequelae in neurocritical care survivors. Databases were searched for terms related to critical illness, intensive care, and outcomes from January 1970 to March 2022. English-language studies of critically ill adults with a primary neurological diagnosis were included if they reported on at least one outcome of interest: cognition, mental health, HRQoL or employment. Data extraction was performed in duplicate for prespecified variables related to study outcomes. Of 16,036 abstracts screened, 74 citations were identified for inclusion. The studies encompassed seven worldwide regions and eight neurocritical diagnosis categories. Publications reporting outcomes of interest increased from 3 before the year 2000 to 71 after. Follow-up time points included ≤ 1 (n = 15 [20%] citations), 3 (n = 28 [38%]), 6 (n = 28 [38%]), and 12 (n = 21 [28%]) months and 1 to 5 (n = 19 [26%]) and > 5 years (n = 8 [11%]), with 28 (38%) citations evaluating outcomes at multiple time points. Sixty-six assessment tools were used to evaluate the four outcomes of interest: 22 evaluating HRQoL (56 [76%] citations), 21 evaluating cognition (20 [27%] citations), 21 evaluating mental health (18 [24%] citations), and 2 evaluating employment (9 [12%] citations). This scoping review aimed to better understand the literature landscape regarding nonphysical outcomes in survivors of neurocritical care. Although a rising number of publications highlight growing awareness, future efforts are needed to improve study consistency and comparability and characterize outcomes in a disease-specific manner, including outlining of a minimum core outcomes set and associated assessment tools.

Depression Negatively Impacts Dyadic Quality of Life Following Neuro-ICU Admission: A Prospective Study of Cognitively Intact Patients and Caregivers

BACKGROUND

Admission to a neurological intensive care unit (Neuro-ICU) can increase risk for depressive and anxiety symptoms for both patients and caregivers. To better understand the long-term mental health impact of a Neuro-ICU admission, we examined the dyadic interdependence between depression and anxiety at Neuro-ICU admission with 3-month quality of life (QoL) for patients and caregivers in a longitudinal, observational cohort study.

METHOD

We assessed depressive and anxiety symptoms (Hospital Anxiety and Depression Scale; HADS) reported by neurologically intact patients (n = 72) and their caregivers (n = 72) within 2 weeks of Neuro-ICU admission (baseline) and 3-months post-discharge (follow-up). We examined the longitudinal association between dyadic depression and anxiety at Neuro-ICU admission and 3-month QoL (World Health Organization; QOL-BREF) across four domains (Physical, Psychological, Social relationships, and Environmental QoL) in separate actor-partner interdependence models (APIM) for patients and caregivers.

RESULTS

In the overall models, patients' own baseline depression levels were negatively associated with their own 3-month QoL in all domains (β =  - 0.53 to - 0.64, p < 0.001), and for caregivers, only in the psychological (β =  - 0.73, p < .001) and social relationships (β =  - 0.56, p < .001) domains. No actor effects were found for one's own baseline anxiety impacting one's own 3-month QoL. Partner effects for one's own depression were significant for caregivers on patients' 3-month psychological (β =  - 0.26, p < .02) and environmental (β =  - 0.29, p < .03) QoL, as well as for patients on caregiver's 3-month psychological QoL (β = 0.25, p < .02). No partner effects were significant in association with baseline anxiety and 3-month QoL in both patients and caregivers.

CONCLUSION

Neuro-ICU patients' and caregivers' baseline depression has significant negative impacts on their own long-term QoL. Caregivers demonstrate significant negative impacts on patient long-term QoL in domains related to emotional distress and caregiver burden. Early identification of mental health symptoms, especially depression, during Neuro-ICU admission may provide an intervention opportunity to improve QoL post-discharge for both dyad members.

Applying dyadic digital psychological interventions for reducing caregiver burden in the illness context: a systematic review and a meta-analysis protocol

INTRODUCTION

Providing informal care to one's romantic partner who is ill may become a highly distressing and demanding task. Based on the innovative dyadic coping model, several support interventions have been developed to alleviate informal caregivers' burden, including both caregivers' and care receivers' needs. Considering the unique challenges characterising the caregiving phenomenon, such as geographical barriers and time restrictions, digital solutions should be considered. However, there is a lack of research examining the effectiveness of dyadic digital solutions. Thus, this review aims to examine the existing literature on the efficacy of dyadic digital psychological interventions designed for caregivers and their care-receivers couples within the illness context.

METHODS AND ANALYSIS

Randomised controlled trials targeting caregivers' burden among dyads of informal caregivers and care receivers will be identified via an electronic search of the following databases: PubMed, Embase, the Cochrane Library, Cinhal, Scopus, PsycINFO, MEDLINE and supplemented by hand searching of previous systematic reviews. The search will be undertaken following the PICO (population, intervention, comparison and outcome) elements. If possible, a meta-analysis will be conducted to examine: (1) the effectiveness of dyadic digital psychological interventions for reducing caregivers' burden (primary outcome) among caregivers who are in a romantic relationship with the care receivers; (2) the effectiveness of dyadic digital psychological interventions on secondary outcomes such as anxiety, depression, stress, quality of life, well-being and self-efficacy among caregivers and care receivers; and (3) moderating effects of clinical and methodological factors on caregivers' burden. Prior to inclusion in the review, retrieved papers will be critically appraised by two independent reviewers. The Cochrane Risk of Bias tool will assess the risk of bias for randomised controlled trials.

ETHICS AND DISSEMINATION

Ethical approval is not required as no primary data will be collected. Findings will be disseminated through peer-reviewed publications, presentations at academic conferences and lay summaries for various stakeholders.

The Recovering Together Initiative: Integrating Psychosocial Care into ICUs

More than 5 million patients are admitted to ICUs each year in the United States alone. ICUs are stressful environments given the patients' medical severity, family emotional experience, and staff burnout. However, psychosocial services are rarely offered and sustained in these settings. Multidisciplinary partnerships and innovative frameworks and services are needed to successfully integrate psychosocial care into these complex settings. To address this need, Massachusetts General Hospital developed the Recovering Together (RT) Initiative (2015-present) in its Neurosciences ICUs (Neuro-ICU). The hospital's aims were threefold: (1) to build a multidisciplinary collaboration to develop and sustain integrative care; (2) to implement a clinical, research, and training (CRT) framework to support patients, families, and staff; and (3) to develop an innovative, tailored evidence-based intervention for patient-caregiver dyads in the Neuro-ICU. The authors detail the process of developing the RT Initiative for the Neuro-ICU, including initial collaborations, psychosocial care implementation, and intervention development. This real-world approach to integrating psychosocial care in this setting was successful because of a strong multidisciplinary partnership, a feasible CRT framework, and funding to support the research and infrastructure. Physical proximity, consistent interactions and communication, mutual trust, and shared leadership priorities helped facilitate this integrated care approach. The findings provide practical guidance on how to integrate psychosocial care into medical settings. The authors hope that this approach is of value to clinicians, researchers, and health care systems working to develop and sustain integrated care models across complex medical settings.

Together from the start: A transdiagnostic framework for early dyadic interventions for neurodegenerative diseases

BACKGROUND

Neurodegenerative diseases (NDDs) are increasingly prevalent and radically alter the lives of individuals and their informal care partners (together called a dyad). As symptoms progress, dyads are at risk for elevated emotional distress and declines in relationship functioning and quality of life. Psychosocial interventions delivered to dyads early after diagnosis have successfully prevented chronic emotional distress across several chronic illnesses including cancer and acute brain injury. Dyads with NDD could benefit from such interventions, however, they are limited. Because NDDs have symptom profiles that are distinct from other chronic illnesses, they require a unique framework and interventions. Given the limited dyadic interventions and unified symptoms across NDDs, a transdiagnostic framework may help to enhance scalability and efficiency. To address this problem, we developed a transdiagnostic framework that cuts across NDD physical and emotional diagnoses to inform cost-effective and sustainable NDD dyadic interventions.

METHODS

To develop this framework, we conducted: (1) a narrative review on dyadic adjustment and existent dyadic interventions for those with NDDs, and (2) integrated findings to develop our NDD transdiagnostic framework for dyadic interventions early after diagnosis.

RESULTS

Findings revealed no existent dyadic interventions for NDDs delivered shortly after diagnosis. Among available interventions, all were delivered later in disease progression, thereby focusing on dyadic challenges at more advanced stages. In addition, although research emphasized the influence of individual, dyadic, and contextual factors on dyads' early adjustment to NDDs, no conceptual model has been developed. Informed by theory and current research, we introduce an NDD transdiagnostic framework for couples' early biopsychosocial adjustment. This framework includes NDD specific: contextual factors, illness-related factors, individual and dyadic stressors, adaptive coping strategies, and dyads' resources.

CONCLUSIONS

Our NDD transdiagnostic framework can be used to inform early dyadic psychosocial interventions that cut across all NDDs. This approach has important implications for implementation and scalability.

Can a Dyadic Resiliency Program Improve Quality of Life in Cognitively Intact Dyads of Neuro-ICU Survivors and Informal Caregivers? Results from a Pilot RCT

BACKGROUND

Neuro-ICU hospitalization for an acute neurological illness is often traumatic and associated with heightened emotional distress and reduced quality of life (QoL) for both survivors and their informal caregivers (i.e., family and friends providing unpaid care). In a pilot study, we previously showed that a dyadic (survivor and caregiver together) resiliency intervention (Recovering Together [RT]) was feasible and associated with sustained improvement in emotional distress when compared with an attention placebo educational control. Here we report on changes in secondary outcomes assessing QoL.

METHODS

Survivors (n = 58) and informal caregivers (n = 58) completed assessments at bedside and were randomly assigned to participate together as a dyad in the RT or control intervention (both 6 weeks, two in-person sessions at bedside and four sessions via live video post discharge). We measured QoL domain scores (physical health, psychological, social relations, and environmental), general QoL, and QoL satisfaction using the World Health Organization Quality of Life Abbreviated Instrument at baseline, post treatment, and 3 months' follow-up. We conducted mixed model analyses of variance with linear contrasts to estimate (1) within-group changes in QoL from baseline to post treatment and from post treatment to 3 months' follow-up and (2) between-group differences in changes in QoL from baseline to post treatment and from post treatment to 3 months' follow-up.

RESULTS

We found significant within-group improvements from baseline to post treatment among RT survivors for physical health QoL (mean difference 1.73; 95% confidence interval [CI] 0.39-3.06; p = 0.012), environmental QoL (mean difference 1.29; 95% CI 0.21-2.36; p = 0.020), general QoL (mean difference 0.55; 95% CI 0.13-0.973; p = 0.011), and QoL satisfaction (mean difference 0.87; 95% CI 0.36-1.37; p = 0.001), and those improvements sustained through the 3-month follow-up. We found no significant between-group improvements for survivors or caregivers from baseline to post treatment or from post treatment to 3 months' follow-up for any QoL variables (i.e., domains, general QoL, and QoL satisfaction together).

CONCLUSIONS

In this pilot study, we found improved QoL among survivors, but not in caregivers, who received RT and improvements sustained over time. These RT-related improvements were not significantly greater than those observed in the control. Results support a fully powered randomized controlled trial to allow for a definitive evaluation of RT-related effects among dyads of survivors of acute brain injury and their caregivers.
