Patterns of depressive symptoms in caregivers of mechanically ventilated critically ill adults from intensive care unit admission to 2 months postintensive care unit discharge: a pilot study

Association between family caregiver competence and dependency in patients discharged from the Intensive Care Unit

OBJECTIVE

To determine the association between the competence (knowledge, skill and preparation) of the family caregiver and the degree of dependency of patients discharged from Intensive Care Unit.

METHOD

A descriptive, cross-sectional study was carried out to characterize family caregivers and patients discharged from the ICU with moderate, severe or total dependence according to Barthel score. Competence was measured with the application of the CUIDAR instrument and caregiver performance (execution of activities in a specific situation) with an instrument that evaluated the performance of actions aimed at supplying basic needs of feeding, elimination, body hygiene, skin care, oxygen therapy and medication administration in a sample of 140 caregivers.

RESULTS

A positive association was found between patient functionality and caregiver performance (Spearman rho: 0.38; p < .001). In contrast, no significant correlation was observed between the self-perception of caregiver competence assessed with the CUIDAR instrument and the patient's functionality, measured by the Barthel scale (Spearman rho: 0.12; p = .16). The 69.3% of the participants had a medium or low competence, only (30.7%) were classified at a high level. The lowest scores were obtained in knowledge (62.9%), followed by uniqueness (32.9%).

CONCLUSION

There is a significant association between patient functionality and objectively assessed caregiver performance; thus, caregivers of more dependent patients have significant challenges to achieve adequate performance in their role.

Preliminary efficacy of the vidatalkTM communication application on family psychological symptoms in the intensive care unit: A pilot study

BACKGROUND

Family caregivers of ICU patients experience difficulty communicating with patients during mechanical ventilation. Little is known about patient-family communication in the ICU and the associated emotional distress.

OBJECTIVES

To examine the preliminary effects of the VidaTalk™ communication app on anxiety, depression, and PTSD-related symptoms among family caregivers.

METHODS

We conducted a prospective study using repeated measures to compare VidaTalk™ to an attention control condition. Twenty-eight family caregivers of nonvocal adult ICU patients participated in this study. The intervention group received VidaTalk™, whereas the attention control group received a standard tablet loaded with MyChart Bedside (EPIC) and game apps during the patient's mechanical ventilation treatment. Family caregiver anxiety and depression (Hospital Anxiety and Depression Scale) were measured at baseline, at extubation/ICU discharge, and 1-, 3-, and 6-months post-ICU discharge. PTSD-related symptoms (Impact of Event Scale-revised) were measured at 1-, 3-, and 6-months. T-tests were used for group comparisons for families' perceived communication difficulty, anxiety, and depression, and Mann-Whitney U tests were used for PTSD-related symptom comparisons.

RESULTS

No statistically significant difference was found between groups in changes in family psychological outcomes, the VidaTalk™ was associated with a small to medium improvement in anxiety symptoms (d = 0.43) at one month. The VidaTalk™ group had lower PTSD-related symptoms than the AC group with a medium effect size (ɳ2=0.07) at one month and a medium-to-large effect size (ɳ2=0.09) at three months.

CONCLUSIONS

The VidaTalk™ demonstrated potential as a family caregiving intervention that may be associated with reduced family psychological symptoms.

Associations between Post-Intensive Care Syndrome Domains in Cardiac Arrest Survivors and Their Families One Month Post-Event

Background: Post-intensive care syndrome (PICS) affects many critical care survivors and family members. Nevertheless, the relationship between PICS-relevant domains in cardiac arrest (CA) survivors and psychological distress in their family members (henceforth, PICS-F) remains underexplored. Methods: We enrolled consecutive CA patients admitted between 16 August 2021 and 28 June 2023 to an academic medical center, along with their close family members, in prospective studies. Survivors' PICS domains were: physical dependence (Physical Self-Maintenance Scale, PSMS), cognitive impairments (Modified Telephone Interview for Cognitive Status, TICS-M), and post-traumatic stress disorder (PTSS) symptoms (PTSD Checklist-PCL 5), as well as PICS-F (PCL-5 Total Score). Hierarchical multivariate linear regressions examined associations between PICS-F and survivors' PICS domains. Results: Of 74 dyads (n = 148), survivors had a mean (SD) age of 56 ± 16 years, with 61% being male and with a median hospital stay of 28 days. Family members (43% spouses) were slightly younger (52 ± 14 years), predominantly female (72%), and of minority race/ethnicity (62%). A high prevalence of PICS assessed 28.5 days (interquartile range 10-63) post-CA was observed in survivors (78% physical dependence, 54% cognitive impairment, 30% PTSS) and in family members (30% PTSS). Survivor PTSS was significantly associated with family member distress (β = 0.3, p = 0.02), independent of physical dependence (β = 0.0, p = 0.9), cognitive impairment (β = -0.1, p = 0.5), family member characteristics, and duration of hospitalization. Conclusions: Both CA survivors and their family members showed substantial evidence of likely PICS. Survivor PTSS is notably associated with family member distress, highlighting the need for dyadic interventions to enhance psychosocial outcomes.

Postintensive care syndrome family: A comprehensive review

Families of critically ill patients are predisposed to tremendous burdens when their relatives are admitted to the intensive care unit (ICU). Postintensive care syndrome family (PICS-F) can be described as a devastated life, encompassing psychological, physical, and socioeconomical burdens that begin with the emotional impact experienced by the family when the patient is admitted to the ICU. PICS-F was primarily proposed as a clinically significant psychological impairment, but it needs to be extended beyond the psychological impairment of the family to include physical and socioeconomical impairments in the future. The prevalence of physiological problems including depression, anxiety and post-traumatic syndrome is 20-40%, and that of non-physiological problems including fatigue is 15% at 6 months after the ICU stay. Assessment of PICS-F was frequently conducted at 3- or 6-month points, although the beginning of the evaluation was based on different assessment points among each of the studies. Families of ICU patients need to be given and understand accurate information, such as the patient's diagnosis, planned care, and prognosis. Prevention of PICS-F requires a continuous bundle of multifaceted and/or multidisciplinary interventions including providing a family information leaflet, ICU diary, communication facilitators, supportive grief care, and follow-up, for the patient and families from during the ICU stay to after discharge from the ICU. This is the first comprehensive review of PICS-F to address the concept, risk factors, assessment tools, prevalence, and management to prevent PICS-F to facilitate acute care physicians' understanding of PICS-F.

Benefits of personal music listening for family caregivers of critically ill patients during the post-COVID era

Objective

This descriptive study surveyed family caregivers of patients in intensive care units (ICUs) during the COVID-19 pandemic to examine the impact of musical listening on their psychological well-being.

Method

The data collected in this study compared with collected from similar research conducted before the COVID-19 pandemic in 2017. The previous study had 195 participants, and the current study had 92. To measure the participants' psychological well-being, the Korean version of the Center for Epidemiologic Studies Depression Scale and the World Health Organization Quality of Life Scale were administered. An investigator-constructed questionnaire was also used to collect information related to participants' engagement in music activities including music listening in their everyday lives and their perceptions of music's benefits.

Results

A two-way ANOVA showed significant effects for time (e.g., before vs. during COVID-19) and involvement in personal music listening (yes vs. no) on current emotional state, with family caregivers reporting significantly greater negative emotions during COVID-19 than before and personal music listening having a positive effect on perceived emotions. For quality of life there was no significant time effect, while the listening effect was statistically significant, indicating a significantly higher quality of life in the group who engaged in music listening in their everyday lives compared to the group who did not. There were no significant time or listening effects for perceived level of depression.

Conclusion

Given the COVID-19 situation and the need to transition to a post-pandemic era, this study suggests that music listening can be an effective option for family caregivers to implement as a resource for attenuating emotional distress and enhancing self-care.

Identification of risk factors for post-intensive care syndrome in family members (PICS-F) among adult patients: a systematic review

INTRODUCTION

Relatives of critically ill patients who either die or survive the intensive care unit (ICU) may develop substantial mental health problems that are collectively defined as post-intensive care syndrome in family (PICS-F).

MATERIAL AND METHODS

By using a systematised search strategy we included studies that focused on PICS-F in relatives of adult ICU patients and reported the risk factors associated with its development. The search was conducted within PubMed, Embase, SCOPUS, clinicaltrials.gov, and Cochrane Library on the 23 August 2022. PRISMA 2020 guidelines were implemented for appropriate reporting. The objective was to document all possible risk factors associated with the development of PICS-F.

RESULTS

We included 51 papers covering 9302 relatives. The frequency of PICS-F varied between 2.5 and 69%. We identified 51 different risk factors of PICS-F, among which we distinguished patient-related ( n = 16), relative-related ( n = 27), and medical staff-related ( n = 8) risk factors. Among 21 studies of the highest quality, we identified the 33 variables associated with the development of PICS-F, of which younger age of a patient, death of a patient, depression in relatives during the ICU stay, history of mental disorders in relatives, being a female relative, being a spouse, and having low satisfaction with communication and care in the ICU were the most commonly reported risk factors.

CONCLUSIONS

PICS-F is a highly frequent phenomenon that can be exacerbated by several risk factors. Special attention should be paid to relatives of younger patients with worse prognosis and with the following relative-related risk factors: female sex, being a spouse, and history of mental health disorders. Finally, the medical staff play a role in preventing the PICS-F development, not only by maintenance of proper communication, but also by early identification of relatives prone to PICS-F.

Psychological Attachment Orientation and Long-Term Posttraumatic Stress Symptoms Among Family Members of ICU Patients

To determine the degree to which an ICU patient’s family member having an “anxious” psychologic attachment orientation is a risk factor for developing long-term posttraumatic stress disorder (PTSD) symptoms following patient ICU discharge or death.

What the American Journal of Critical Care Junior Peer Reviewers Were Reading During the First Year of the Program: Caring for Patients With COVID-19

The Junior Peer Reviewer program of the American Journal of Critical Care provides mentorship in the peer review process to novice reviewers. The program includes discussion sessions in which participants review articles published in other journals to practice and improve their critical appraisal skills. The articles reviewed during the first year of the program focused on caring for patients with COVID-19. The global pandemic has placed a heavy burden on nursing practice. Prone positioning of patients with acute respiratory failure is likely to improve their outcomes. Hospitals caring for patients needing prolonged ventilation should use evidence-based, standardized care practices to reduce mortality. The burden on uncompensated caregivers of COVID-19 survivors is also high, and such caregivers are likely to require assistance with their efforts. Reviewing these articles was helpful for building the peer review skills of program participants and identifying actionable research to improve the lives of critically ill patients.

A multicentre evaluation exploring the impact of an integrated health and social care intervention for the caregivers of ICU survivors

Background

Caregivers and family members of Intensive Care Unit (ICU) survivors can face emotional problems following patient discharge from hospital. We aimed to evaluate the impact of a multi-centre integrated health and social care intervention, on caregiver and family member outcomes.

Methods

This study evaluated the impact of the Intensive Care Syndrome: Promoting Independence and Return to Employment (InS:PIRE) programme across 9 sites in Scotland. InS:PIRE is an integrated health and social care intervention. We compared caregivers who attended this programme with a contemporary control group of ICU caregivers (usual care cohort), who did not attend.

Results

The primary outcome was anxiety measured via the Hospital Anxiety and Depression Scale at 12 months post-hospital discharge. Secondary outcome measures included depression, carer strain and clinical insomnia. A total of 170 caregivers had data available at 12 months for inclusion in this study; 81 caregivers attended the InS:PIRE intervention and completed outcome measures at 12 months post-hospital discharge. In the usual care cohort of caregivers, 89 completed measures. The two cohorts had similar baseline demographics. After adjustment, those caregivers who attended InS:PIRE demonstrated a significant improvement in symptoms of anxiety (OR: 0.42, 95% CI: 0.20–0.89, p = 0.02), carer strain (OR: 0.39; 95% CI: 0.16–0.98 p = 0.04) and clinical insomnia (OR: 0.40; 95% CI: 0.17–0.77 p < 0.001). There was no significant difference in symptoms of depression at 12 months.

Conclusions

This multicentre evaluation has shown that caregivers who attended an integrated health and social care intervention reported improved emotional health and less symptoms of insomnia, 12 months after the delivery of the intervention.

Mental health symptoms in family members of COVID-19 ICU survivors 3 and 12 months after ICU admission: a multicentre prospective cohort study

Purpose

Long-term mental outcomes in family members of coronavirus disease 2019 (COVID-19) intensive care unit (ICU) survivors are unknown. Therefore, we assessed the prevalence of mental health symptoms, including associated risk factors, and quality of life (QoL) in family members of COVID-19 ICU survivors 3 and 12 months post-ICU.

Methods

A prospective multicentre cohort study in ICUs of ten Dutch hospitals, including adult family members of COVID-19 ICU survivors admitted between March 1, and July 1, 2020. Symptom prevalence rates of anxiety, depression (Hospital Anxiety and Depression Scale) and Post-Traumatic Stress Disorder (Impact of Event Scale-6), and QoL (Short Form-12) before ICU admission (baseline), and after 3 and 12 months were measured. Additionally, associations between family and patient characteristics and mental health symptoms were calculated.

Results

A total of 166 out of 197 (84.3%) included family members completed the 12-month follow-up of whom 46.1% and 38.3% had mental health symptoms 3 and 12 months post-ICU, respectively; both higher compared to baseline (22.4%) (p < 0.001). The mental component summary score of the SF-12 was lower at 12-month follow-up compared with baseline [mean difference mental component score: − 5.5 (95% confidence interval (CI) − 7.4 to − 3.6)]. Furthermore, 27.9% experienced work-related problems. Symptoms of anxiety (odds ratio (OR) 9.23; 95% CI 2.296–37.24; p = 0.002) and depression (OR 5.96; 95% CI 1.29–27.42; p = 0.02) prior to ICU admission were identified as risk factors for mental health symptoms after 12 months.

Conclusion

A considerable proportion of family members of COVID-19 survivors reported mental health symptoms 3 and 12 months after ICU admission, disrupting QoL and creating work-related problems.

Caregiver burden and emotional wellbeing in informal caregivers to ICU survivors-A prospective cohort study

BACKGROUND

Informal caregivers to intensive care unit (ICU) survivors may develop post-intensive care syndrome family (PICS-F), including depression, anxiety and post-traumatic stress (PTS). Our primary aim was to investigate associations between caregiver burden in informal caregivers cohabiting with ICU survivors and patients' physical and psychological outcomes.

METHODS

A prospective, multicentre cohort study in four ICUs in Sweden. Adults cohabiting with ICU patients included in a previous study were eligible for inclusion. Three months post-ICU, informal caregivers received questionnaires assessing caregiver burden, health-related quality of life (HRQL) and symptoms of depression, anxiety and PTS. In parallel, patients reported their three-month physical and psychological status via validated questionnaires. The primary outcome of this study was to compare caregiver burden in informal caregivers to patients with and without adverse physical and psychological outcomes 3 months post-ICU. Secondary outcomes were correlations between caregiver burden and informal caregivers' mental HRQL.

RESULTS

Among 62 included informal caregivers, 55 (89%) responded to the follow-up questionnaires. Caregiver burden was higher among informal caregivers to patients with an adverse outcome, compared to informal caregivers to patients without an adverse outcome, caregiver burden scale score mean (±standard deviation) 52 (11) and 41 (13) respectively (p = 0.003). There was strong negative correlation between caregiver burden and informal caregivers' mental HRQL (r_s -0.74, p < 0.001).

CONCLUSION

Informal caregivers to ICU survivors with adverse physical or psychological outcome experience a higher caregiver burden. A higher caregiver burden correlates with worse caregiver mental HRQL. ICU follow-up programs should consider screening and follow-up of informal caregivers for mental health problems.

Psychological Symptoms in Relatives of Critically Ill Patients: A Longitudinal Cohort Study

OBJECTIVES

To explore the psychologic impact of an ICU stay on relatives and to determine patient and relative factors, including their pre-ICU mental health status, associated with psychologic symptoms 3 months after ICU admission.

DESIGN

A prospective, exploratory, longitudinal cohort study.

SETTING

A 12-bed ICU in a Dutch tertiary teaching hospital.

PATIENTS

The relatives of ICU patients admitted between March 2018 and December 2019.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Relatives completed the Hospital Anxiety and Depression Scale shortly after patients' ICU admission referring to the week before ICU admission and 3 months later, together with the Impact of Event Scale-Revised, assessing posttraumatic stress. A total of 387 were eligible of which 78 (20%) responded. Almost a quarter reported an increase of anxiety (23.1%) and depression (24.4%) between baseline and 3 months follow-up. One in six (17.9%) reported posttraumatic stress. Anxiety, depression, and posttraumatic stress at 3 months follow-up were significantly associated with preexisting anxiety and depression. Patients' factor associated with depression 3 months follow-up in relatives was length of ICU stay (odds ratio, 1.09; 95% CI, 1.02-1.16).

CONCLUSIONS

Relatives with preexisting psychologic symptoms before ICU admission are at risk to develop anxiety, depression, or posttraumatic stress shortly after ICU discharge of the patient. Screening and identification in an early stage enables early interventions to prevent relatives from worsening mental health during and after ICU admission.

A Whirlpool of Stress in Families of Intensive Care Unit Patients: A Qualitative Multicenter Study

BACKGROUND

Family members of patients admitted to the intensive care unit must tolerate high levels of stress, making them emotionally and physically vulnerable. However, little is known about the kinds of stress family members may experience.

OBJECTIVE

To explore perceived stress in the families of patients admitted to the intensive care unit.

METHODS

This qualitative content analysis study involved 23 family members of patients admitted to intensive care units. Participants were drawn from family members of patients hospitalized in intensive care units of 3 public and 2 private hospitals. Data were collected through semistructured interviews.

RESULTS

Three themes emerged from the data: "distrust," "repeated stress exposure," and "a whirlpool of persistent negative emotional-physical state." The first theme had 2 categories: "fearful mindset" and "negative beliefs about professional caregivers." The second theme also had 2 categories: "fear of the future" and "sustained accumulation of tensions." The third theme had 3 categories: "impaired mental health," "impaired physical health," and "impaired family function."

CONCLUSIONS

The findings of this study may help critical care nurses better understand the nature and sources of family stresses during a patient's intensive care unit stay. Supervisory nurses should alert their staff to these issues so that family care programs can address them, thereby reducing family members' risk of posttraumatic stress disorder and post-intensive care syndrome-family.

Advocating for a Loved One in the Setting of Uncertainty: A Mixed-Methods Study Among Caregivers of Sepsis Survivors at the Point of a Sepsis Readmission

BACKGROUND

The trajectory of recovery after sepsis varies. Survivors may have considerable ongoing limitations, requiring a caregiver for a prolonged period.

OBJECTIVES

To learn about experiences, quality of life, coping, resilience, and social support of caregiver caring for survivors of sepsis.

METHODS

We conducted a convergent mixed-methods study, recruiting informal caregivers of patients who had survived sepsis in the past year and were readmitted to the intensive care unit with sepsis. Individual face-to-face, semistructured interviews and validated surveys on quality of life, coping, caregiver burden, resilience, and social support were administered to caregivers. Interview transcripts were analyzed using content analysis. Surveys were scored and summarized using descriptive statistics.

RESULTS

Caregivers were primarily middle-aged, White, and female. Half were spouses of their care recipient. Caregivers reported some deficits in mobility, pain, and anxiety/depression. Coping styles varied, with engaged coping being more prevalent. Most caregivers reported mild to moderate burden, all reported either normal or high resilience levels, and types of social support were similar. However, interviews and survey findings were not always consistent. Major themes that emerged from the analysis included (1) advocating for and protecting their loved one, (2) coping with caregiving, (3) uncertain future, (4) rewards of caregiving, and (5) need to optimize communication with family.

DISCUSSION

Caregivers of sepsis survivors are protective of their care recipient and use a variety of strategies to advocate for their loved one and to cope with the uncertainty involved in a new intensive care unit admission. More advocacy and support are needed for this population.

Theorising survivorship after intensive care: A systematic review of patient and family experiences

AIMS AND OBJECTIVE

This systematic literature review explores and maps what we know about survivorship to understand how survivorship can be theoretically defined.

BACKGROUND

Survivorship of critical illness has been identified as a challenge for the 21st Century. Whilst the use of the term 'survivorship' is now common in critical care, it has been borrowed from the cancer literature where the discourse on what survivorship means in a cancer context is ongoing and remains largely descriptive. In the absence of a theoretical understanding, the term 'survivorship' is often used in critical illness in a generic way, limiting our understanding of what survivorship is. The current COVID-19 pandemic adds to an urgency of understanding what intensive care unit (ICU) survivorship might mean, given the emerging long-term consequences of this patient cohort. We set out to explore how survivorship after critical illness is being conceptualised and what the implications might be for clinical practice and research.

DESIGN

Integrated systematic literature review. The review protocol was registered with PROSPERO International Prospective Register of Systematic Reviews. PRISMA guidelines were followed and a PRISMA checklist for reporting systematic reviews completed.

RESULTS

The three main themes around which the reviewed studies were organised are: (a) healthcare system; (b) ICU survivors' families; and (c) ICU survivor's identity. These three themes feed into an overarching core theme of 'ICU Survivorship Experiences'. These themes map our current knowledge of what happens when a patient survives a critical illness and where we are in understanding ICU survivorship.

CONCLUSION

We mapped in this systematic review the different pieces of the jigsaw that emerge following critical illness to understand and see the bigger picture of what happens after patients survive critical illness. It is evident that existing research has mapped these connections, but what we have not managed to do yet is defining what survivorship is theoretically. We offer a preliminary definition of survivorship as a process but are aware that this definition needs to be developed further with patients and families.

Positive Appraisal of Caregiving for Intensive Care Unit Survivors: A Qualitative Secondary Analysis

BACKGROUND

More than half of intensive care unit survivors require assistance from family caregivers after discharge. Caregiving is associated with negative consequences including poor health-related quality of life, psychosocial distress, and burden. Little is known about how family caregivers find satisfaction and meaning in their experience.

OBJECTIVES

To explore positive descriptions of the experiences of family caregivers of critically ill patients and to describe factors that family caregivers view as important to a positive caregiving experience from hospitalization to 4 months after discharge.

METHODS

Qualitative secondary analysis was performed on data from semistructured interviews conducted as part of a longitudinal study that examined physical and psychological responses to stress in a convenience sample of family caregivers of adult intensive care unit patients who underwent prolonged mechanical ventilation (≥ 4 days). Interviews were conducted at 4 time points: during the hospitalization and within 2 weeks, 2 months, and 4 months after discharge.

RESULTS

Participants (n = 41) reported factors that helped them positively appraise their caregiving experience in 113 interviews conducted face to face or via telephone. During patients' hospitalization, caregivers described changes in their role, with their primary responsibility being to advocate for the patient. They described how this experience fulfilled their identity and strengthened their relationship with the patient. Most family caregivers mentioned the importance of social support and prayer.

CONCLUSIONS

Family caregivers of intensive care unit patients can identify positive aspects of caregiving during the experience. Interventions to reframe the caregiving experience in a positive light are warranted.

Depression and Change in Caregiver Burden Among Family Members of Intensive Care Unit Survivors

BACKGROUND

Family members of patients in intensive care units may experience psychological distress and substantial caregiver burden.

OBJECTIVE

To evaluate whether change in caregiver burden from intensive care unit admission to 3-month follow-up is associated with caregiver depression at 3 months.

METHODS

Caregiver burden was assessed at enrollment and 3 months later, and caregiver depression was assessed at 3 months. Depression was measured with the Hospital Anxiety and Depression Score. The primary analysis was the association between depression at 3 months and change in caregiver burden, controlling for a history of caregiver depression.

RESULTS

One hundred one participants were enrolled; 65 participants had a surviving loved one and completed 3-month follow-up. At 3-month follow-up, 12% of participants met criteria for depression. Increased caregiver burden over time was significantly associated with depression at follow-up (Fisher exact test, P = .004), although this association was not significant after controlling for self-reported history of depression at baseline (Cochran-Mantel-Haenszel test, P = .23).

CONCLUSIONS

Family members are increasingly recognized as a vulnerable population susceptible to negative psychological outcomes after a loved one's admission to the intensive care unit. In this small sample, no significant association was found between change in caregiver burden and depression at 3 months after controlling for baseline depression.

Psychological Sequelae in Family Caregivers of Critically III Intensive Care Unit Patients. A Systematic Review

Rationale: Family members of critically ill patients hospitalized in the intensive care unit (ICU) often become caregivers, and they are at risk to develop adverse psychological outcomes. There is a need to understand the psychological impact of critical illness on family caregivers. Objectives: The aim of this systematic review is to document the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) in family caregivers of critically ill patients and identify potential risk factors for psychological outcomes to inform clinical and future research recommendations. Methods: A literature search for psychological outcomes for family caregivers of critically ill patients was conducted. A total of 1,148 studies from PsycINFO, CINAHL, Web of Science, SCOPUS, and Medline were identified. Results: Forty studies met inclusion criteria and were included in the review. The prevalence of psychological outcomes in family caregivers ranged from 4% to 94% for depression, 2% to 80% for anxiety, and 3% to 62% for PTSD. Caregiver depression, anxiety, and PTSD decreased in most studies that assessed longitudinal outcomes. Common risk factors identified for adverse psychological outcomes included younger caregiver age, caregiver relationship to the patient, lower socioeconomic status, and female sex. Conclusions: The prevalence of depression, anxiety, and PTSD varies greatly across studies of family caregivers of critically ill patients. This finding highlights the need for more systematic investigations of psychological outcomes and the implementation of clinical interventions to prevent or reduce depression, anxiety, and PTSD in family caregivers of critically ill patients.

Outcomes and experiences of relatives of patients discharged home after critical illness: a systematic integrative review

BACKGROUND

Patients discharged from intensive care may experience psychological and physical deficits resulting in a long and complex rehabilitation upon discharge. Relatives are also vulnerable to psychological pathologies and diminished health-related quality of life following the patients' critical illness. Relatives often provide care during the patients' rehabilitation, which may influence their health.

AIM

To report the outcomes and experiences of relatives of patients discharged home after critical illness.

DESIGN

Systematic integrative review.

METHODS

Electronic databases Cumulative Index of Nursing and Allied Health Literature, PubMed, Embase®, and PsychINFO® were searched using keywords, synonyms, and medical subject headings. Reference lists of articles and critical care journals were manually searched. Studies eligible for inclusion reported primary research and were published in English between 2007 and 2017. Studies were appraised using the Critical Appraisal Skills Programme checklists. Data were extracted and then analysed according to framework.

FINDINGS

Twenty-five studies were included: 19 quantitative, 4 qualitative, and 1 mixed method study. Three themes were identified: health and well-being, employment and lifestyle, and caregiving role. Health and well-being reports the incidence and significance of psychological morbidity such as post-traumatic stress disorder, anxiety, and depression. Employment and lifestyle describes the impact of caregiving on the relative's ability to work and engage in usual social activities. The final theme describes and discusses the caregiving role in terms of activities of daily living, knowledge and skills, and adaption to the role.

CONCLUSIONS

There is a significant and meaningful impact on outcomes and experiences of relatives of patients discharged home after critical illness. Relatives' caregiving is embedded within the context of their psychological morbidity and social adjustment.

RELEVANCE TO PRACTICE

If informal care giving is to be sustainable, there is a need to design effective strategies of supporting families through all stages of the critical illness trajectory.

Home discharge following critical illness: A qualitative analysis of family caregiver experience

BACKGROUND

Few studies have longitudinally explored the experience and needs of family caregivers of ICU survivors after patients' home discharge.

METHODS

Qualitative content analysis of interviews drawn from a parent study that followed family caregivers of adults ICU survivors for 4 months post-ICU discharge.

RESULTS

Family caregivers (n = 20, all white, 80% woman) viewed home discharge as positive progress, but reported having insufficient time to transition from family visitor to the active caregiver role. Caregivers expressed feelings of relief during the steady recovery of family members' physical and cognitive function. However, the slow pace of improvement conflicted with their expectations. Even after patients achieved independent physical function, emotional needs persisted and these issues contributed to caregivers' anxiety, worry, and view that recovery was incomplete.

CONCLUSION

Family caregivers of ICU survivors need information and skills to help managing patients' care needs, pacing expectations with actual patients' progress, and caregivers' health needs.

Multiple Symptoms in Family Caregivers of Intensive Care Unit Patients

CONTEXT

Intensive care unit (ICU) patients experience physical and psychological challenges related to ICU admission in the acute and recovery phases after a critical illness. Involvement of family caregivers (FCs) is essential in the patients' struggle to survive critical illness. FCs report a high symptom burden related to ICU admission. Previous research has investigated mainly single symptoms. Little is known about multiple symptom burden related to FC experiences in an ICU.

OBJECTIVE

This study aimed: 1) to describe the occurrence, severity, and distress related to multiple symptoms in FCs of ICU patients, and 2) to identify associations between the background characteristics and symptom burden of FCs.

METHODS

This cross-sectional study investigated multiple symptoms in adult FCs of ICU patients. FCs completed a self-report symptom assessment questionnaire within 2 weeks after the patient's admission to the ICU.

RESULTS

FCs (N=211) experienced a median of 9 (range 0-24) symptoms, among which, worrying (91%) was the most occurring. Severity and distress varied between symptoms. Younger age, being a spouse of an ICU patient, and having more comorbidities were significantly associated with the number of symptoms.

CONCLUSIONS

FCs of ICU patients experience multiple symptoms, among which, psychological symptoms are most occurring. Age, relationship to the patient, and comorbidities were significantly associated with the number of symptoms reported by FCs. Comprehensive symptom assessment may identify FCs who are at risk of developing a high symptom burden when the patient is admitted to the ICU.

Addressing spirituality during critical illness: A review of current literature

OBJECTIVES

The purpose of this review is to provide an overview of research on spirituality and religiosity in the intensive care setting that has been published since the 2004-2005 American College of Critical Care Medicine (ACCM) Clinical Practice Guidelines for the Support of Family in the Patient-Centered Intensive Care Unit with an emphasis on its application beyond palliative and end-of-life care.

MATERIALS AND METHODS

ACCM 2004-2005 guidelines emphasized the importance of spiritual and religious support in the form of four specific recommendations: [1] assessment and incorporation of spiritual needs in ICU care plan; [2] spiritual care training for doctors and nurses; [3] physician review of interdisciplinary spiritual need assessments; and [4] honoring the requests of patients to pray with them. We reviewed 26 studies published from 2006 to 2016 and identified whether studies strengthened the grade of these recommendations. We further categorized findings of these studies to understand the roles of spirituality and religiosity in surrogate perceptions and decision-making and patient and family experience.

CONCLUSIONS

Spiritual care has an essential role in the treatment of critically ill patients and families. Current literature offers few insights to support clinicians in navigating this often-challenging aspect of patient care and more research is needed.

Evaluation of a strategy for enrolling the families of critically ill patients in research using limited human resources

RATIONALE

Clinical trials of interventions aimed at the families of intensive care unit (ICU) patients have proliferated but recruitment for these trials can be challenging.

OBJECTIVES

To evaluate a strategy for recruiting families of patients currently being treated in an ICU using limited human resources and time-varying daily screening over 7 consecutive days.

METHODS

We screened the Johns Hopkins Hospital medical ICU census 7 days per week to identify eligible family members. We then made daily, in-person attempts to enroll eligible families during a time-varying 2-hour enrollment period until families declined participation, consented, or were no longer eligible.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the proportion of eligible patients for whom ≥1 family member was enrolled. Secondary outcomes included enrollment of legal healthcare proxies, the consent rate among families approached for enrollment, and success rates for recruiting at different times during the day and week. Among 284 eligible patients, 108 (38%, 95% CI 32%-44%) had ≥1 family member enrolled, and 75 (26%, 95% CI 21%-32%) had their legal healthcare proxy enrolled. Among 117 family members asked to participate, 108 (92%, 95% CI 86%-96%) were enrolled. Patients with versus without an enrolled proxy were more likely to be white (44% vs. 30%, P = .02), live in a zip code with a median income of ≥$100,000 (15% vs. 5%, P = .01), be mechanically ventilated (63% vs. 47%, P = .01), die in the ICU (19% vs. 9%, P = .03), and to have longer ICU stays (median 5.0 vs. 1.8 days, P<.001). Day of the week and time of day were not associated with family presence in the ICU or consent rate.

CONCLUSIONS

Family members were recruited for more than one third of eligible patients, and >90% of approached consented to participate. There are important demographic differences between patients with vs without an enrolled family member.

Psychological and Physical Health in Family Caregivers of Intensive Care Unit Survivors: Current Knowledge and Future Research Strategies

PURPOSE

This article provides an overview of current knowledge on the impact of caregiving on the psychological and physical health of family caregivers of intensive care unit (ICU) survivors and suggestions for future research.

METHODS

Review of selected papers published in English between January 2000 and October 2015 reporting psychological and physical health outcomes in family caregivers of ICU survivors.

RESULTS

In family caregivers of ICU survivors followed up to five years after patients' discharge from an ICU, psychological symptoms, manifested as depression, anxiety and post-traumatic stress disorder, were highly prevalent. Poor self-care, sleep disturbances and fatigue were identified as common physical health problems in family caregivers. Studies to date are mainly descriptive; few interventions have targeted family caregivers. Further, studies that elicit unique needs of families from diverse cultures are lacking.

CONCLUSION

Studies to date have described the impact of caregiving on the psychological and physical health in family caregivers of ICU survivors. Few studies have tested interventions to support unique needs in this population. Therefore, evidence for best strategies is lacking. Future research is needed to identify ICU caregivers at greatest risk for distress, time points to target interventions with maximal efficacy, needs of those from diverse cultures and test interventions to mitigate family caregivers' burden.

The impact of the patient post-intensive care syndrome components upon caregiver burden

OBJECTIVE

To evaluate patient post-intensive care syndrome (PICS-P) and caregiver burden 3 months after discharge from the Intensive Care Unit (ICU) and determine the impact of different components of PICS-P upon caregiver burden.

DESIGN

A prospective observational study was conducted over 26 months (January 2013-February 2015).

SETTING

Medical-surgical ICU and follow-up consultation in Portugal.

PATIENTS OR PARTICIPANTS

Patients discharged after a minimum of 2 days in the ICU. Caregiver inclusion criteria: not paid, written and spoken Portuguese, and agreement to participate in the study.

MAIN VARIABLES OF INTEREST

In ICU: Patient gender, age, severity of illness (SAPS II) and length of ICU stay. At 3 months caregiver burden, physical (reduced mobility, weakness acquired in the ICU) and psychological components of PICS (anxiety, depression, post-traumatic stress disorder).

RESULTS

A total of 168 caregivers completed the survey (response rate of 69%). A low degree of overburden was reported by 34.5% of caregivers, while 15.5% showed moderate to high levels of overburden. Patient anxiety and depression 3 months after ICU discharge significantly influenced the presence of caregiver burden (p=0.030 vs p=0.008). When physical components of PICS-P were evaluated, no influence on caregiver burden was observed. Patient demographics, severity of illness and length of stay also failed to influence caregiver burden.

CONCLUSIONS

The presence of psychological components of PICS-P 3 months after ICU seems to have a negative impact upon caregiver burden. On the other hand, physical problems showed no important impact upon caregiver overburden.

One-Year Outcomes in Caregivers of Critically Ill Patients

BACKGROUND

Few resources are available to support caregivers of patients who have survived critical illness; consequently, the caregivers' own health may suffer. We studied caregiver and patient characteristics to determine which characteristics were associated with caregivers' health outcomes during the first year after patient discharge from an intensive care unit (ICU).

METHODS

We prospectively enrolled 280 caregivers of patients who had received 7 or more days of mechanical ventilation in an ICU. Using hospital data and self-administered questionnaires, we collected information on caregiver and patient characteristics, including caregiver depressive symptoms, psychological well-being, health-related quality of life, sense of control over life, and effect of providing care on other activities. Assessments occurred 7 days and 3, 6, and 12 months after ICU discharge.

RESULTS

The caregivers' mean age was 53 years, 70% were women, and 61% were caring for a spouse. A large percentage of caregivers (67% initially and 43% at 1 year) reported high levels of depressive symptoms. Depressive symptoms decreased at least partially with time in 84% of the caregivers but did not in 16%. Variables that were significantly associated with worse mental health outcomes in caregivers were younger age, greater effect of patient care on other activities, less social support, less sense of control over life, and less personal growth. No patient variables were consistently associated with caregiver outcomes over time.

CONCLUSIONS

In this study, most caregivers of critically ill patients reported high levels of depressive symptoms, which commonly persisted up to 1 year and did not decrease in some caregivers. (Funded by the Canadian Institutes of Health Research and others; ClinicalTrials.gov number, NCT00896220.).

Reported burden on informal caregivers of ICU survivors: a literature review

BACKGROUND

Critical illness and the problems faced after ICU discharge do not only affect the patient, it also negatively impacts patients' informal caregivers. There is no review which summarizes all types of burden reported in informal caregivers of ICU survivors. It is important that the burdens these informal caregivers suffer are systematically assessed so the caregivers can receive the professional care they need. We aimed to provide a complete overview of the types of burdens reported in informal caregivers of adult ICU survivors, to make recommendations on which burdens should be assessed in this population, and which tools should be used to assess them.

METHOD

We performed a systematic search in PubMed and CINAHL from database inception until June 2014. All articles reporting on burdens in informal caregivers of adult ICU survivors were included. Two independent reviewers used a standardized form to extract characteristics of informal caregivers, types of burdens and instruments used to assess these burdens. The quality of the included studies was assessed using the Newcastle-Ottawa and the PEDro scales.

RESULTS

The search yielded 2704 articles, of which we included 28 in our review. The most commonly reported outcomes were psychosocial burden. Six months after ICU discharge, the prevalence of anxiety was between 15% and 24%, depression between 4.7% and 36.4% and post-traumatic stress disorder (PTSD) between 35% and 57.1%. Loss of employment, financial burden, lifestyle interference and low health-related quality of life (HRQoL) were also frequently reported. The most commonly used tools were the Hospital Anxiety and Depression Scale (HADS), Centre for Epidemiological Studies-Depression questionnaire, and Impact of Event Scale (IES). The quality of observational studies was low and of randomized studies moderate to fair.

CONCLUSIONS

Informal caregivers of ICU survivors suffer a substantial variety of burdens. Although the quality of the included studies was poor, there is evidence that burden in the psychosocial field is most prevalent. We suggest screening informal caregivers of ICU survivors for anxiety, depression, PTSD, and HRQoL using respectively the HADS, IES and Short Form 36 and recommend a follow-up period of at least 6 months.

Depressive symptoms and anxiety in intensive care unit (ICU) survivors after ICU discharge

BACKGROUND

The association between intensive care unit (ICU) survivors' psychological sequelae, individual care needs, and discharge disposition has not been evaluated.

OBJECTIVE

To describe depressive symptoms and anxiety in ICU survivors and explore these symptoms based on individual care needs and discharge disposition for 4 months post-ICU discharge.

METHODS

We analyzed data from 39 ICU survivors who self-reported measures of depressive symptoms (Center for Epidemiologic Studies-Depression 10 items [CESD-10]) and anxiety (Shortened Profile of Mood States-Anxiety subscale [POMS-A]).

RESULTS

A majority of patients reported CESD-10 scores above the cut off (≥ 8) indicating risk for clinical depression. POMS-A scores were highest within 2 weeks post-ICU discharge and decreased subsequently. Data trends suggest worse depressive symptoms and anxiety when patients had moderate to high care needs and/or were unable to return home.

CONCLUSION

ICU survivors who need caregiver assistance and extended institutional care reported trends of worse depressive symptoms and anxiety.

Short-Term Trajectories of Depressive Symptoms in Stroke Survivors and Their Family Caregivers

GOAL

We utilize group-based trajectory modeling (GBTM) to delineate depressive symptom trajectories among stroke survivor-caregiver dyads, to identify predictors of the delineated trajectories, and to assess the influence of time-varying covariates (stroke survivor depressive symptoms and functional disability, caregiver depressive symptoms, and foreign domestic worker [FDW] assistance) on the level of the depressive symptom trajectories.

METHODS

Data on 172 stroke survivor-caregiver dyads in Singapore, for whom depressive symptoms were assessed thrice (baseline/3 months/6 months), were utilized. GBTM was applied to delineate depressive symptom trajectories, and to identify their predictors and time-varying covariates.

FINDINGS

Three stroke survivor depressive symptom trajectories (low and decreasing [47.6%], low and increasing [43.1%], and high and increasing [9.3%]) and 2 caregiver depressive symptom trajectories (low and stable [71.5%] and high and decreasing [28.5%]) were delineated. Caregivers with chronic diseases were more likely (odds ratio [95% confidence interval]: 8.09[2.04-32.07]) and those caring for older stroke survivors (0.94[0.90-0.98]) were less likely to follow the high and decreasing than the low and stable depressive symptom trajectory. An increase in stroke survivor functional disability and caregiver depressive symptoms led to a rise (~worsening) in stroke survivor depressive symptom trajectories. Whereas an increase in stroke survivor depressive symptoms led to a rise in caregiver depressive symptom trajectories, FDW assistance led to a decline (~improvement).

CONCLUSION

Care professionals should be mindful of heterogeneity in depressive symptom patterns over time among stroke survivor-caregiver dyads. Reciprocal association of depressive symptoms in the stroke survivor-caregiver dyad suggests that addressing mood problems in 1 member may benefit the other member, and calls for dyadic mental health interventions.

Psychosocial outcomes in informal caregivers of the critically ill: a systematic review

OBJECTIVE

The objective of the review was to evaluate and synthesize the prevalence, risk factors, and trajectory of psychosocial morbidity in informal caregivers of critical care survivors.

DATA SOURCES

A systematic search of MEDLINE, PsychInfo, PubMed, CINAHL, Cochrane Library, Scopus, PILOTS, EMBASE, and Physiotherapy Evidence Database was undertaken between January and February 2014.

STUDY SELECTION

Citations were screened independently by two reviewers for studies that investigated psychosocial outcomes (depression, anxiety, stress, posttraumatic stress disorder, burden, activity restriction, and health-related quality of life) for informal caregivers of critical care survivors (mechanically ventilated for 48 hr or more).

DATA EXTRACTION

Data on study outcomes were extracted into a standardized form and quality assessed by two independent reviewers using the Newcastle-Ottawa Scale, the Physiotherapy Evidence Database, and the National Health and Medical Research Council Hierarchy of Evidence guide. Preferred Reporting Items for Systematic Reviews guidelines were followed.

DATA SYNTHESIS

Fourteen studies of 1,491 caregivers were included. Depressive symptoms were the most commonly reported outcome with a prevalence of 75.5% during critical care and 22.8-29% at 1-year follow-up. Risk factors for depressive symptoms in caregivers included female gender and younger age. The greatest period of risk for all outcomes was during the patient's critical care admission although psychological symptoms improved over time. The overall quality of the studies was low.

CONCLUSIONS

Depressive symptoms were the most prevalent in informal caregivers of survivors of intensive care who were ventilated for more than 48 hours and persist at 1 year with a prevalence of 22.8-29.0%, which is comparable with caregivers of patients with dementia. Screening for caregiver risks could be performed during the ICU admission where intervention can be implemented and then evaluated. Further high-quality studies are needed to quantify anxiety, stress, caregiver burden, and posttraumatic stress disorder outcomes in informal caregivers of long-stay patients surviving ICU.

Recognizing, naming, and measuring a family intensive care unit syndrome

Most major decisions in the intensive care unit (ICU) regarding goals of care are shared by clinicians and someone other than the patient. Multicenter clinical trials focusing on improved communication between clinicians and these surrogate decision makers have not reported consistently improved outcomes. We suggest that acquired maladaptive reasoning may contribute importantly to failure of the intervention strategies tested to date. Surrogate decision makers often suffer significant psychological morbidity in the form of stress, anxiety, depression, and post-traumatic stress disorder. Family members in the ICU also suffer cognitive blunting and sleep deprivation. Their decision-making abilities are eroded by anticipatory grief and cognitive biases, while personal and family conflicts further impact their decision making. We propose recognizing a family ICU syndrome to describe the morbidity and associated decision-making impairment experienced by many family members of patients with acute critical illness (in the ICU) and chronic critical illness (in the long-term, acute care hospital). Research rigorously using models of compromised decision making may help elucidate both mechanisms of impairment and targets for intervention. Better quantifying compromised decision making and its relationship to poor outcomes will allow us to formulate and advance useful techniques. The use of decision aids and improving ICU design may provide benefit now and in the near future. In measuring interventions targeting cognitive barriers, clinically significant outcomes, such as time to decision, should be considered. Statistical approaches, such as survival models and rank statistic testing, will increase our power to detect differences in our interventions.

Fatigue in family caregivers of adult intensive care unit survivors

CONTEXT

Family caregivers are a vital resource in the recovery of intensive care unit (ICU) survivors. Of concern, the stress associated with this role can negatively affect caregiver health. Fatigue, an important health indicator, has been identified as a predictor of various illnesses, greater use of health services, and early mortality. Examining the impact of fatigue on caregivers' physical health can assist in identifying critical time points and potential targets for intervention.

OBJECTIVES

To describe self-reported fatigue in caregivers of ICU survivors from patients' ICU admission to ≤ 2 weeks, two- and four-months post-ICU discharge.

METHODS

Patient-caregiver pairs were enrolled from a medical ICU. Caregiver fatigue was measured using the Short-Form 36 Health Survey Vitality subscale (SF-36 Vitality). Caregiver psychobehavioral stress responses included depressive symptoms, burden, health risk behaviors, and sleep quality. Patient data included self-reported physical symptoms and disposition (home vs. institution).

RESULTS

Forty-seven patient-caregiver pairs were initially enrolled. Clinically significant fatigue (SF-36 Vitality ≤ 45) was reported by 43%-53% of caregivers across the time points, and these caregivers reported worse scores in measures of depressive symptoms, burden, health risk behaviors and sleep quality, and patients' symptom burden. In 26 caregivers with data for all time points (55% of the total sample), SF-36 Vitality scores showed trends of improvement when the patient returned home and greater impairment when institutionalization continued.

CONCLUSION

In caregivers of ICU survivors, fatigue is common and potentially linked with poor psychobehavioral responses. Worsening fatigue was associated with greater symptom distress and long-term patient institutionalization.

Advance directives lessen the decisional burden of surrogate decision-making for the chronically critically ill

AIMS AND OBJECTIVES

To identify the relationships between advance directive status, demographic characteristics and decisional burden (role stress and depressive symptoms) of surrogate decision-makers (SDMs) of patients with chronic critical illness.

BACKGROUND

Although the prevalence of advance directives among Americans has increased, SDMs are ultimately responsible for complex medical decisions of the chronically critically ill patient. Decisional burden has lasting psychological effects on SDMs. There is insufficient evidence on the influence of advance directives on the decisional burden of surrogate decision-makers of patients with chronic critical illness.

DESIGN

The study was a secondary data analysis of cross-sectional data. Data were obtained from 489 surrogate decision-makers of chronically critically ill patients at two academic medical centres in Northeast Ohio, United States, between September 2005-May 2008.

METHODS

Data were collected using demographic forms and questionnaires. A single-item measure of role stress and the Center for Epidemiological Studies Depression (CESD) scale were used to capture the SDM's decisional burden. Descriptive statistics, t-tests, chi-square and path analyses were performed.

RESULTS

Surrogate decision-makers who were nonwhite, with low socioeconomic status and low education level were less likely to have advance directive documentation for their chronically critically ill patient. The presence of an advance directive mitigates the decisional burden by directly reducing the SDM's role stress and indirectly lessening the severity of depressive symptoms.

CONCLUSIONS

Most SDMs of chronically critically ill patients will not have the benefit of knowing the patient's preferences for life-sustaining therapies and consequently be at risk of increased decisional burden.

RELEVANCE TO CLINICAL PRACTICE

Study results are clinically useful for patient education on the influence of advance directives. Patients may be informed that SDMs without advance directives are at risk of increased decisional burden and will require decisional support to facilitate patient-centred decision-making.
