Well-being in informal caregivers of survivors of acute respiratory distress syndrome*

Caregiver burden and impact on COVID-19 patient participation and quality of life one year after ICU discharge - A prospective cohort study

OBJECTIVES

to investigate changes in caregiver strain, mental health complaints and QoL in caregivers of COVID-19 ICU survivors in the first year after discharge, and their associations with patients' participation and quality of life.

METHODS

Post-ICU COVID-19 survivors, needing inpatient rehabilitation and their informal caregivers were included. Caregiver self-administered questionnaires included quality of life, self-rated health, caregiver strain, anxiety and depression symptoms, post-traumatic stress and coping style. Patients' participation in society was assessed and quality of life.

RESULTS

67 patients (78% male) and 57 caregivers (23.6% male) were included. Three months post-ICU, caregivers experienced caregiver strain (32%), anxiety (41%), depressive symptoms (16%) and PTSD (24%). One year post-ICU, rates decreased, still being 11%, 26%, 10% and 5%, respectively. Caregiver anxiety symptoms and self-rated health at three months were associated with worse patient levels of participation and quality of life one year after ICU discharge (p < 0.05).

CONCLUSIONS

COVID-19 caregivers experience high levels of mental health complaints one year after a patient's ICU discharge. Furthermore, our results indicate that patient participation levels and quality of life one year after ICU discharge may be negatively associated by caregiver complaints.

PRACTICAL IMPLICATIONS

Counselling and routine assessment of emotional complaints and unmet needs of the informal caregiver should be incorporated and addressed in the rehabilitation treatment of (COVID-19) post-ICU patients.

Family burden after critical illness: the forgotten caregivers

OBJECTIVE

To determine the incidence of primary caregiver burden in a cohort of family members of critically ill patients admitted to ICU and to identify risk factors related to its development in both the patient and the family member.

DESIGN

Prospective observational cohort study was conducted for 24 months.

SETTING

Hospital Universitario Clínico San Cecilio, Granada.

PATIENTS

The sample was the primary caregivers of all patients with risk factors for development of PICS (Post-Intensive Care Syndrome).

INTERVENTIONS

The follow-up protocol consisted of evaluation 3 months after discharge from the ICU in a specific consultation.

MAIN VARIABLES OF INTEREST

The scales used in patients were Barthel, SF-12, HADS, Pfeiffer, IES-6 and in relatives the Apgar and Zarit.

RESULTS

A total of 93 patients and caregivers were included in the follow-up. 15 relatives did not complete the follow-up questionnaires and were excluded from the study. The incidence of PICS-F (Family Post Intensive Care Syndrome) defined by the presence of primary caregiver burden in our cohort of patients is 34.6% (n=27), 95% CI 25.0-45.7. The risk factors for the development of caregiver burden are the presence of physical impairment, anxiety or post-traumatic stress in the patient, with no relationship found with the characteristics studied in the family member.

CONCLUSIONS

One out of 3 relatives of patients with risk factors for the development of PICS presents at 3 months caregiver burden. This is related to factors dependent on the patient's state of health.

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.

Heart rate variability and subsequent psychological distress among family members of intensive care unit patients

Objective

To determine whether heart rate variability (HRV; a physiological measure of acute stress) is associated with persistent psychological distress among family members of adult intensive care unit (ICU) patients.

Methods

This prospective study investigated family members of patients admitted to a study ICU. Participants’ variability in heart rate tracings were measured by low frequency (LF)/high frequency (HF) ratio and detrended fluctuation analysis (DFA). Questionnaires were completed 3 months after enrollment to ascertain outcome rates of anxiety, depression, and post-traumatic stress disorder (PTSD).

Results

Ninety-nine participants were enrolled (median LF/HF ratio, 0.92 [interquartile range, 0.64–1.38]). Of 92 participants who completed the 3-month follow-up, 29 (32%) had persistent anxiety. Logistic regression showed that LF/HF ratio (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.43, 1.53) was not associated with 3-month outcomes. In an exploratory analysis, DFA α (OR 0.93, 95% CI 0.87, 0.99), α₁ (OR 0.97, 95% CI 0.94, 0.99), and α₂ (OR 0.94, 95% CI 0.88, 0.99) scaling components were associated with PTSD development.

Conclusion

Almost one-third of family members experienced anxiety at three months after enrollment. HRV, measured by LF/HF ratio, was not a predictor of psychologic distress, however, exploratory analyses indicated that DFA may be associated with PTSD outcomes.

Informal family caregiver experiences with publicly funded home care in Ontario

Publicly funded home care in Ontario, Canada, is a critical component of the health care system. Over the last few decades the sector has undergone numerous reforms impacting the funding and provision of services. In light of this, the purpose of this study was to examine the lived experiences of informal family caregivers who seek in-home publicly funded care for their relatives. In doing so, the goal was to understand the circumstances and challenges faced by these individuals in accessing care and obtaining respite from their duties. This knowledge is fundamental to the health care system which seeks to prevent institutionalization as well as to minimize health care costs associated with the physical and psychological outcomes of informal caregiving.

Systematic review of 29 self-report instruments for assessing quality of life in older adults receiving aged care services

BACKGROUND

Quality of life (QoL) outcomes are used to monitor quality of care for older adults accessing aged care services, yet it remains unclear which QoL instruments best meet older adults', providers' and policymakers' needs. This review aimed to (1) identify QoL instruments used in aged care and describe them in terms of QoL domains measured and logistical details; (2) summarise in which aged care settings the instruments have been used and (3) discuss factors to consider in deciding on the suitability of QoL instruments for use in aged care services.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, Cochrane Library and CINAHL from inception to 2021.

ELIGIBILITY CRITERIA

Instruments were included if they were designed for adults (>18 years), available in English, been applied in a peer-reviewed research study examining QoL outcomes in adults >65 years accessing aged care (including home/social care, residential/long-term care) and had reported psychometrics.

DATA EXTRACTION AND SYNTHESIS

Two researchers independently reviewed the measures and extracted the data. Data synthesis was performed via narrative review of eligible instruments.

RESULTS

292 articles reporting on 29 QoL instruments were included. Eight domains of QoL were addressed: physical health, mental health, emotional state, social connection, environment, autonomy and overall QoL. The period between 1990 and 2000 produced the greatest number of newly developed instruments. The EuroQoL-5 Dimensions (EQ-5D) and Short Form-series were used across multiple aged care contexts including home and residential care. More recent instruments (eg, ICEpop CAPability measure for Older people (ICECAP-O) and Adult Social Care Outcomes Toolkit (ASCOT)) tend to capture emotional sentiment towards personal circumstances and higher order care needs, in comparison with more established instruments (eg, EQ-5D) which are largely focused on health status.

CONCLUSIONS

A comprehensive list of QoL instruments and their characteristics is provided to inform instrument choice for use in research or for care quality assurance in aged care settings, depending on needs and interests of users.

Post Intensive Care Syndrome (PICS): an overview of the definition, etiology, risk factors, and possible counseling and treatment strategies

INTRODUCTION

Post-intensive care syndrome (PICS) has only recently been recognized as a new clinical entity in patients surviving their intensive care unit (ICU) stay due to critical illness. With increasing survival rates of ICU patients worldwide, there is a rising interest regarding post-ICU recovery.

AREAS COVERED

First, based on the current literature a definition is provided of PICS, including the domains of impairments that comprise PICS along with the etiology and risk factors. Second, preventive measures and possible treatment strategies integrated in the follow-up care are described. Third, the authors will discuss the current SARS-Cov-2 pandemic and the increased risk of PICS in these post-ICU patients and their families.

EXPERT OPINION

PICS is a relatively new entity, which not only encompasses various physical, cognitive, and psychological impairments but also impacts global health due to long-lasting detrimental socioeconomic burdens. Importantly, PICS also relates to caregivers of post-ICU patients. Strategies to reduce this burden will not only be needed within the ICU setting but will also have to take place in an interdisciplinary, multifaceted approach in primary care settings. Additionally, the SARS-Cov-2 pandemic has a high burden on post-ICU patients and their relatives.

Gender Differences in Longitudinal Associations Between Intimate Care, Resiliency, and Depression Among Informal Caregivers of Patients Surviving the Neuroscience Intensive Care Unit

BACKGROUND/OBJECTIVE

Informal caregivers (e.g., family and friends) are at risk for developing depression, which can be detrimental to both caregiver and patient functioning. Initial evidence suggests that resiliency may reduce the risk of depression. However, gender differences in associations between multiple psychosocial resiliency factors and depression have not been examined among neuroscience intensive care unit (neuro-ICU) caregivers. We explored interactions between caregiver gender and baseline resiliency factors on depression symptom severity at baseline through 3 and 6 months post-discharge.

METHODS

Caregivers (N = 96) of neuro-ICU patients able to provide informed consent to participate in research were enrolled as part of a prospective, longitudinal study in the neuro-ICU of a major academic medical center. Caregiver sociodemographics and resiliency factors (coping, mindfulness, self-efficacy, intimate care, and preparedness for caregiving) were assessed during the patient's hospitalization (i.e., baseline). Levels of depressive symptoms were measured using the Hospital Anxiety and Depression Scale at baseline, 3 months, and 6 months post-discharge.

RESULTS

Baseline depressive symptoms predicted depressive symptoms at both 3- and 6-month follow-ups, with no difference at any time point in rates of depression by gender. At baseline, greater levels of coping, mindfulness, and preparedness for caregiving were individually associated with lower levels of concurrent depression regardless of gender (ps < 0.006). The main effect of baseline coping remained significant at 3-month follow-up (p = 0.045). We observed a trend-level interaction between gender and baseline intimate care, such that among male caregivers only, high baseline intimate care was associated with lower depression at 3-month follow-up (p = 0.055). At 6-month follow-up, we observed a significant interaction between caregiver gender and baseline intimate care, such that male caregivers reporting high intimate care reported lower symptoms of depression than females reporting high intimate care (p = 0.037).

CONCLUSIONS

Results support implementation of psychosocial resiliency interventions for caregivers of patients admitted to the neuro-ICU early in the recovery process. Male caregivers may particularly benefit from strategies focused on increasing intimate care (e.g., physical and emotional affection with their loved one) and quality of the patient-caregiver dyadic relationship.

Usability and acceptability of a mobile application prototype for a combined behavioural activation and physical rehabilitation intervention in acute respiratory failure survivors

BACKGROUND

Acute respiratory failure survivors experience depression symptoms and new impairments in physical function. Behavioural activation, an evidence-based nonpharmacological treatment for depression, combined with physical rehabilitation, is a promising intervention. Notably, mHealth applications (Apps) are potentially effective methods of delivering home-based interventions.

OBJECTIVES

The objective of this study was to evaluate the usability and acceptability of a prototype App to deliver a combined, home-based behavioural activation and rehabilitation intervention to acute respiratory failure survivors.

METHODS

A prospective user-preference study was conducted with acute respiratory failure survivors and self-designated care partners. Survivors were adults with at least mild depression symptoms before hospital discharge who received mechanical ventilation in the intensive care unit for ≥24 h. Survivors and care partners reviewed the App during a single in-person home visit and completed the System Usability Scale (range: 0-100; score >73 considered "good") and a semistructured interview.

RESULTS

Ten patient/care partner dyads completed study. The median [interquartile range] patient age was 50 [40-64] years, and 50% were female. The median System Usability Scale scores among patients and care partners were 76 [68-83] and 88 [75-94], respectively. Qualitative feedback supported usability and acceptability of the App, with three themes reported: (1) stigma associated with depression, (2) App as a motivator for recovery, and (3) App providing multidisciplinary support for survivor and care partner.

CONCLUSIONS

A mobile App prototype designed to deliver a combined behavioural activation and rehabilitation intervention was usable and acceptable to survivors of acute respiratory failure and their care partners. Given the reported stigma associated with depression, the self-directed App may be particularly valuable for motivation and multidisciplinary support.

Health problems among family caregivers of former intensive care unit (ICU) patients: an interview study

Background

Family caregivers of former intensive care unit (ICU) patients may suffer from physical and mental problems owing to ICU hospitalisation of their loved ones. These problems can have a major impact on their daily lives. Little is known about experienced consequences of ICU hospitalisation on caregivers in general practice.

Aim

To explore health problems in family caregivers of former ICU patients and the consequences in their daily lives.

Design & setting

Semi-structured interviews with family caregivers of former critically ill patients treated in a Dutch ICU.

Method

Purposively sampled relatives of former ICU patients were interviewed between April and May 2019. Interviews were conducted until data saturation was reached. Interviews were then thematically analysed.

Results

In total, 13 family caregivers were interviewed. The interviews took place 3 months to 3 years after ICU discharge. Expressed problems were categorised into six themes: (1) physical functioning (for example, tiredness, headache, and feeling sick more often); (2) mental health (for example, anxiety, more stress and difficulty in expressing emotions); (3) existential dimension and future (for example, uncertainty about the future); (4) quality of life (for example, losing freedom in life); (5) relationship and social participation (for example, experiencing a lack of understanding); and (6) daily functioning (for example, stopping working).

Conclusion

Caregivers experience several health problems, even years after their relative's ICU episode. Healthcare providers should be focused not only on former ICU patients’ health, but also on their caregivers’, and need to signal and identify caregivers' health problems earlier in order to give them the appropriate care and support they need.

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.

Impact of Patient and Family Involvement in Long-Term Outcomes

Surviving a critical illness can have long-term effects on both patients and families. These effects can be physical, emotional, cognitive, and social, and they affect both the patient and the family. Family members play a key role in helping their loved one recover, and this recovery process can take considerable time. Transferring out of an intensive care unit, and discharging home from a hospital, are important milestones, but they represent only the beginning of recovery and healing after a critical illness. Recognizing that these challenges exist both for patients and families is important to improve critical illness outcomes.

Novel Risk Factors for Posttraumatic Stress Disorder Symptoms in Family Members of Acute Respiratory Distress Syndrome Survivors

OBJECTIVES

Family members of ICU survivors report long-term psychologic symptoms of posttraumatic stress disorder. We describe patient- and family-member risk factors for posttraumatic stress disorder symptoms among family members of survivors of acute respiratory distress syndrome.

DESIGN

Prospective cohort study of family members of acute respiratory distress syndrome survivors.

SETTING

Single tertiary care center in Seattle, Washington.

SUBJECTS

From 2010 to 2015, we assembled an inception cohort of adult acute respiratory distress syndrome survivors who identified family members involved in ICU and post-ICU care. One-hundred sixty-two family members enrolled in the study, corresponding to 120 patients.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Family members were assessed for self-reported psychologic symptoms 6 months after patient discharge using the Posttraumatic Stress Disorder Checklist-Civilian Version, the Patient Health Questionnaire 9-item depression scale, and the Generalized Anxiety Disorder 7-item scale. The primary outcome was posttraumatic stress disorder symptoms, and secondary outcomes were symptoms of depression and anxiety. We used clustered multivariable logistic regression to identify patient- and family-member risk factors for psychologic symptoms. Posttraumatic stress disorder symptoms were present in 31% (95% CI, 24-39%) of family participants. Family member risk factors for posttraumatic stress disorder symptoms included preexisting mental health disorders (adjusted odds ratio, 3.22; 95% CI, 1.42-7.31), recent personal experience of serious physical illness (adjusted odds ratio, 3.07; 95% CI, 1.40-6.75), and female gender (adjusted odds ratio, 5.18; 95% CI, 1.74-15.4). Family members of previously healthy patients (Charlson index of zero) had higher frequency of posttraumatic stress disorder symptoms (adjusted odds ratio, 2.25; 95% CI, 1.06-4.77). Markers of patient illness severity were not associated with family posttraumatic stress disorder symptoms.

CONCLUSIONS

The prevalence of long-term posttraumatic stress disorder symptoms among family members of acute respiratory distress syndrome survivors is high. Family members with preexisting mental health disorders, recent experiences of serious physical illness, and family members of previously healthy patients are at increased risk for posttraumatic stress disorder symptoms.

Engaging Patients and Families to Help Research Inform and Advance Patient and Family-Centered Care in Critical Care Medicine

Intensive care unit (ICU) patient, and family member engagement is evolving in both critical care medicine practice and research. The results of two qualitative critical care research projects led by ICU survivors and family members show how patient-partner research training can inform the critical care community of meaningful priorities in the traumatic ICU context. The resulting creation of a prioritized list of critical care research topics builds further on the construct of patient-centered care.

Stressors and strains of next of kin of patients with ARDS in intensive care: A qualitative interview study using a stress-strain approach

OBJECTIVES

This study aims to explore and analyse the stressors and strains of next of kin of acute respiratory distress syndrome (ARDS) patients during their stay in the intensive care unit utilising the stressors and strain approach as a theoretical framework.

METHODS

Data collection was performed as semi-standardised qualitative interviews. 35 families of patients with ARDS were approached when visiting the intensive care unit. Participants were recruited until thematic saturation was reached; finally, 17 persons (age ranging from 26 to 71 years, nine women) took part. Systematic content analysis was conducted on the theoretical foundations of the stressors and strain approach.

FINDINGS

Numerous stressors were identified; they can be divided into three main categories: in relation to organising the visit, occurring during the visit and arising at home. These stressors were reported highly consistently throughout participants. However, the strains resulting from these stressors were varying in manifestation and level.

CONCLUSIONS

This study explores the manifold stressors and strains of next of kin of a critically ill patient. Some stressors are inherent to the life-threatening condition of a family member; others arise from the health care system and could be modified. The level of strain experienced depends on social support, individual coping skills and life circumstances.

Patient-centered Outcomes Research in Pulmonary, Critical Care, and Sleep Medicine. An Official American Thoracic Society Workshop Report

Patient-centered outcomes research (PCOR) represents a paradigm shift in research methods aimed to create the body of evidence that supports clinical practice and informs health care decisions. PCOR integrates patients and other key stakeholders including family members, policy makers, clinicians, and patient advocates and advocacy groups as research partners throughout all stages of the research process. The importance of PCOR has received increased recognition, yet there is little evidence available to help guide researchers interested in the design and conduct of PCOR. In May 2014, we convened a workshop to identify key issues related to designing, conducting, and disseminating findings from PCOR studies. Workshop participants included a diverse group of patients, patient advocates, clinicians (physicians, nurses, psychologists, and advanced practice providers), researchers, administrators, and funders within and beyond the pulmonary, critical care, and sleep medicine communities. Participants identified important issues and considerations to address when undertaking PCOR. In this report, we summarize the results of this workshop to inform members of the pulmonary, sleep, and critical care community interested in participating in PCOR. Key findings include the following: 1) requirements for research to be considered PCOR; 2) the potential significant impact of PCOR on patients, clinicians, and researchers; 3) guiding principles and practical strategies to form successful patient-centered research partnerships, conduct PCOR, and disseminate study results to a broad audience of stakeholders; 4) benefits and challenges of PCOR for researchers; and 5) resources available within the American Thoracic Society to help with the conduct of PCOR.

The Effectiveness of Psychoeducational and Financial Intervention to Support Caregivers of Individuals With Alzheimer's Disease in Poland

Background and Objectives

The goal of this study is to create data-driven guidelines and tools for caregivers and health care professionals that will enable caregivers to be prepared for future caregiving-related challenges and decrease their levels of stress.

Research Design and Methods

A total of 60 spousal caregivers of individuals with Alzheimer’s disease (AD) living in Poland were recruited for this study. The participants were assigned to two different groups. The intervention group was provided with a five-session training focused on teaching coping strategies for managing difficult behaviors and provided with a stipend for a period of 6 months (a financial aid program recently launched by the local agency). A control group was not provided with any of the interventions but asked to complete the questionnaires. The effectiveness of each intervention was assessed at a baseline and 6 months after baseline evaluation.

Results

Caregivers who received financial and educational training reported significantly decreased levels of depression and caregiver burden in comparison to the control group. The majority of caregivers emphasized that caregiving created financial problems and that their work has been underestimated by the government.

Discussion and Implications

This project addresses several issues of central importance to the success of building research foundation for the interventions. The results have the potential of generating more efficient and personalized interventions that address the needs of the caregiver as they occur, leading to increased knowledge of AD and decreased levels of depression and caregiver burden.

Impact of post-traumatic stress symptoms on the health-related quality of life in a cohort study with chronically critically ill patients and their partners: age matters

Background

Survivors of an acute critical illness with continuing organ dysfunction and uncontrolled inflammatory responses are prone to become chronically critically ill. As mental sequelae, a post-traumatic stress disorder and an associated decrease in the health-related quality of life (QoL) may occur, not only in the patients but also in their partners. Currently, research on long-term mental distress in chronically critically ill patient-partner dyads, using appropriate dyadic analysis strategies (patients and partners being measured and linked on the same variables) and controlling for contextual factors, is lacking.

Methods

The present study investigates the interdependence of post-traumatic stress symptoms (PTSS) and the health-related QoL in n = 70 dyads of chronically critically ill patients and their partners, using the Actor-Partner-Interdependence Model (APIM) under consideration of contextual factors (age, gender, length of partnership). The Post-traumatic Stress Scale (PTSS-10) and Euro-Quality of Life (EQ-5D-3L) were applied in both the patients and their partners, within up to 6 months after the transfer from acute care ICU to post-acute ICU.

Results

Clinically relevant post-traumatic stress symptoms were reported by 17.1% of the patients and 18.6% of the partners. Both the chronically critically ill patients and their partners with more severe post-traumatic stress symptoms also showed a decreased health-related QoL. The latter was more pronounced in male partners compared to female partners or female patients. In younger partners (≤ 57 years), higher values of post-traumatic stress symptoms were associated with a decreased QoL in the patients.

Conclusions

Mental health screening and psychotherapeutic treatment options should be offered to both the chronically critically ill patients and their partners. Future research is required to address the special needs of younger patient-partner dyads, following protracted ICU treatment.

Development of a Web-Based Peer Support Program for Family Caregivers of Ventilator-Assisted Individuals Living in the Community: Protocol for a Pilot Randomized Controlled Trial

Background

Across Europe, Canada, Australia, and the United States, the prevalence of home mechanical ventilation (HMV) prevalence is 6.6-12.9 per 100,000. At-home ventilator-assisted individuals (VAIs) are often vulnerable and highly comorbid, requiring complex care. In Canada, most VAI care is provided by family, leading to poor health-related quality of life and increased caregiver burden. No supportive interventions or peer support programs are tailored to VAI caregivers. Owing to the financial, geographic, and time limitations, Web-based support delivery may especially meet VAI family caregiver needs. We have developed a peer mentor training and Web-based peer support program for VAI caregivers including information-sharing, peer-to-peer communication, and peer mentorship.

Objective

Study Stage 1 aims to (1) evaluate the face and content validity of the peer mentor training program and (2) investigate participant satisfaction. Study Stage 2 aims to evaluate (1) the feasibility of participant recruitment and Web-based program delivery; (2) acceptability, usability, and satisfactoriness; (3) experiences of caregivers and peer mentors with the Web-based peer support program; and (4) effect of the Web-based peer support program on caregiver health outcomes.

Methods

Study Stage 1: We will train 7 caregivers to act as peer mentors for the Web-based peer support program trial; they will complete questionnaires rating the utility of individual training sessions and the training program overall. Study Stage 2: We will recruit 30 caregiver peers for a pilot randomized controlled trial of the 12-week Web-based peer support program using a waitlist control; the program includes private chat, a public discussion forum, and weekly moderated chats. Caregiver peers will be randomized to the intervention or waitlist control group using a 1:1 ratio using Randomize.net. Both groups will complete pre- and postintervention health outcome questionnaires (ie, caregiving impact, mastery, coping, personal gain, positive affect, and depression). Caregiver peers in the intervention arm will only complete a program evaluation and will be invited to participate in an interview to provide insight into their experience. Peer mentors will be invited to participate in a Web-based focus group to provide insight into their experience as mentors. We will judge the feasibility per the number of recruitment and program delivery goals met, use analysis of covariance to compare health outcomes between intervention and control groups, and analyze qualitative data thematically.

Results

Peer mentor training was completed with 5 caregivers in July 2018. To date, 2 caregivers have beta-tested the website, and the Web-based peer support program trial will commence in September 2018. Results are expected by early 2019.

Conclusions

This study will result in the production and initial evaluation of a rigorously developed, evidence- and stakeholder-informed Web-based peer training and peer support program for caregivers of VAIs residing at home.

Quality of life in family caregivers of patients in the intensive care unit: A longitudinal study

BACKGROUND

Family caregivers of patients in the intensive care unit (ICU) experience impairments in the quality of life. Previous studies report that psychological quality of life improves over time, but there has been limited longitudinal research, and measurement points have differed. Factors such as age, gender, and posttraumatic stress symptoms have been found to be associated with the quality of life, but level of hope and its associations with the quality of life have not been investigated.

OBJECTIVES

The objective of this study was (1) to evaluate changes in the quality of life in family caregivers during the first year after a patient's admission to the ICU and (2) to identify associations between patients' and family caregivers' background characteristics, posttraumatic stress symptoms, hope, and quality of life.

METHODS

A longitudinal study design with five measurement points was used. Family caregivers completed study questionnaires at enrolment into the study and at 1, 3, 6, and 12 months after the patient's admission to the ICU. The quality of life was measured with the 12-Item Short Form Health Survey.

RESULTS

Family caregivers (N = 211) reported improved psychological quality of life during the first year after the patient's admission to the ICU, but it was still lower than the psychological quality of life reported in norm-based data. Being on sick leave, consulting healthcare professionals (e.g., general practitioner), and increased level of posttraumatic stress symptoms were significantly associated with psychological quality of life, whereas hope was not. Reported physical quality of life was comparable to norm-based data.

CONCLUSION

Family caregivers of patients in the ICU reported impairments in quality of life during the first year after the patient's admission to the ICU. Being on sick leave, consulting healthcare professionals, and reduced posttraumatic stress symptoms may improve mental quality of life.

Health care utilization and the cost of posttraumatic acute respiratory distress syndrome care

BACKGROUND

Posttraumatic acute respiratory distress syndrome (ARDS) is associated with prolonged mechanical ventilation and longer hospitalizations. The relationship between posttraumatic ARDS severity and financial burden has not been previously studied. We hypothesized that increasing ARDS severity is associated with incrementally higher health care costs.

METHODS

Adults arriving as the highest level of trauma activation were enrolled in an ongoing prospective cohort study. Patients who survived 6 hours or longer are included in the analysis. Blinded review of chest radiographs was performed by two independent physicians for any intubated patient with PaO2:FIO2 ratio of 300 mmHg or lower during the first 8 days of admission. The severity of ARDS was classified by the Berlin criteria. Hospital charge data were used to perform standard costing analysis.

RESULTS

Acute respiratory distress syndrome occurred in 13% (203 of 1,586). The distribution of disease severity was 33% mild, 42% moderate, and 25% severe. Patients with ARDS were older (41 years vs. 35 years, p < 0.01), had higher median Injury Severity Score (30 vs. 10, p < 0.01), more chest injury (Abbreviated Injury Scale score, ≥ 3: 51% vs. 21%, p < 0.01), and blunt mechanisms (85% vs. 53%, p < 0.01). By ARDS severity, there was no significant difference in age, mechanism, or rate of traumatic brain injury. Increasing ARDS severity was associated with higher Injury Severity Score and higher mortality rates. Standardized total hospital charges were fourfold higher for patients who developed ARDS compared with those who did not develop ARDS (US $434,000 vs. US $96,000; p < 0.01). Furthermore, the daily hospital charges significantly increased across categories of worsening ARDS severity (mild, US $20,451; moderate, US $23,994; severe, US $33,316; p < 0.01).

CONCLUSION

The development of posttraumatic ARDS is associated with higher health care costs. Among trauma patients who develop ARDS, total hospital charges per day increase with worsening severity of disease. Prevention, early recognition, and treatment of ARDS after trauma are potentially important objectives for efforts to control health care costs in this population.

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.

Resiliency is independently associated with greater quality of life among informal caregivers to neuroscience intensive care unit patients

OBJECTIVE

Every year, millions of Americans become informal caregivers to loved ones admitted to Neuroscience Intensive Care Units (Neuro-ICU), and face challenges to Quality of Life (QoL). This study sought to identify associations between resiliency, distress, and caregiver QoL at time of Neuro-ICU admission.

METHODS

Informal caregivers (N = 79, M_age = 53, 64% female) of Neuro-ICU patients were recruited and completed self-report questionnaires during the hospitalization. We used hierarchical regression to test relative contributions of caregiver mindfulness, perceived coping abilities, and preparedness for caregiving to caregiver QoL, above-and-beyond non-modifiable patient and caregiver factors (e.g., gender) and caregiver psychological distress (i.e., anxiety, depression, history of mental health conditions).

RESULTS

Preparedness for caregiving was uniquely and positively associated with Physical Health QoL (sr² = 0.07, p = 0.001), Social QoL (sr² = 0.05, p = 0.021), and Environmental QoL (sr2 = 0.14, p < 0.001), even after accounting for psychological distress. Mindfulness was uniquely and positively associated with Physical Health QoL (sr² = 0.12, p < 0.001) and Psychological QoL (sr² = 0.07, p = 0.004), above-and-beyond variance accounted for by psychological distress.

CONCLUSIONS

Mindfulness and preparedness for caregiving emerged as consistent, unique resiliency factors associated with greater caregiver QoL across QoL dimensions. Results highlight the importance of resiliency factors in QoL among Neuro-ICU caregivers and the need for early interventions to support resiliency.

Family-centered outcomes during and after critical illness: current outcomes and opportunities for future investigation

PURPOSE OF REVIEW

Family-centered outcomes during and after critical illness assess issues that are most important to family members. An understanding of family-centered outcomes is necessary to support the provision of family-centered care and to foster development of interventions to improve care and communication in the ICU.

RECENT FINDINGS

Current family-centered outcomes in critical care include satisfaction with care, including end-of-life care, symptoms of psychological distress, and health-related quality of life. Novel measures include assessments of decisional conflict, decision regret, therapeutic alliance, and caregiver burden, as well as positive adaptations and resilience.

SUMMARY

Critical illness places a significant burden on family members. A wide variety of family-centered outcomes are available to guide improvements in care and communication. Future research should focus on developing sensitive and responsive measures that capture key elements of the family member experience during and after critical illness.

Fifty Years of Research in ARDS. Long-Term Follow-up after Acute Respiratory Distress Syndrome. Insights for Managing Medical Complexity after Critical Illness

Critical illness is not a discrete disease state or syndrome. It is the culmination of a multiplicity of heterogeneous disease states and their varied health trajectories leading to extreme illness that requires advanced life support in a distinct geographic location in the hospital. It is a marker of newly acquired or worsened medical complexity and multimorbidities. Fifty years ago, distinguished critical care colleagues identified a syndrome of severe lung injury that united a group of patients with disparate admitting diagnoses. Acute respiratory distress syndrome continues to represent an important, incremental insult and risk modifier of acute and longer-term outcome, but it does not solely define our patients or their outcomes in isolation. Over the next 50 years, our research and clinical agenda needs to sharpen our lens on the fundamental importance of our patients' pre-critical illness health status, their intrinsic susceptibilities to tissue injury, and their innate and varied resiliencies. We need to take responsibility for the contribution that we make to morbidity through our practice in the intensive care unit each day. Engagement in frank and transparent communication with our patients and their caregivers about the very real and morbid consequences of being this sick is essential. We must enforce explicit consent about the morbidity of innovative, experimental, or high-risk medical and surgical procedures and ensure that our ongoing level of treatment aligns with patients' and caregivers' goals and values. Interprofessional and multidisciplinary collaboration is crucial to modify existing complex care pathways for our patients and their families to foster optimal rehabilitation and reintegration into the workplace and community.

A qualitative study of factors that influence active family involvement with patient care in the ICU: Survey of critical care nurses

OBJECTIVE

Family caregiver involvement may improve patient and family outcomes in the intensive care unit. This study describes critical care nurses' approaches to involving family caregivers in direct patient care.

RESEARCH METHODOLOGY & DESIGN

This is a qualitative content analysis of text captured through an electronic survey.

SETTING

A convenience sample of 374 critical care nurses in the United States who were subscribers to one of the American Association of Critical Care Nurses social media sites or electronic newsletters.

MAIN OUTCOME MEASURE

Critical care nurses' responses to five open-ended questions about their approaches to family involvement in direct patient care.

FINDINGS

Nurse, patient and family caregiver factors intersected in the context of the professional practice environment and the available resources for family care. Two main themes were identified: "Involving family caregivers in patient care in the intensive care unit requires careful ssessment" and "There are barriers and facilitators to caregiver involvement in patient care in the intensive care unit."

CONCLUSION

Patient care demands, the professional practice environment and a lack of resources for families hindered nursing family caregiver involvement. Greater attention to these barriers as they relate to family caregiver involvement and clinical outcomes should be a priority in future research.

A longitudinal view of factors that influence the emotional well-being of family caregivers to individuals with heart failure

OBJECTIVES

Caring for community-residing patients with heart failure can affect caregivers' emotional wellbeing. However, few studies have examined caregivers' well-being longitudinally, or identified factors associated with positive and negative outcomes. The objective of this longitudinal cohort study was to examine changes in caregivers' well-being over time, and to identify patient and caregiver factors associated with positive and negative outcomes.

METHOD

Fifty caregiver/heart failure patient dyads were recruited from an acute care facility and followed in the community. All participants completed surveys at hospital admission and 3, 6 and 12 months later. Caregivers completed assessments of depression symptoms and positive affect and standardized measures to capture assistance provided, mastery, personal gain, social support, participation restriction, and patients' behavioral and psychological symptoms. From patients, we collected demographic characteristics and health-related quality of life. Individual Growth Curve modelling was used to analyze the data.

RESULTS

Caregivers' negative and positive emotions remained stable over time. Depression symptoms were associated with higher participation restriction in caregivers. Positive affect was associated with more personal gain and more social support. Patients' health-related quality of life and their behavioral and psychological symptoms were not significantly associated with caregivers' emotional outcomes.

CONCLUSION

Interventions should be offered based on caregivers' needs rather than patients' health outcomes, and should focus on fostering caregivers' feelings of personal gain, assisting them with securing social support, and engaging in valued activities.

Meeting the needs of critical care patients after discharge home: a qualitative exploratory study of patient perspectives

BACKGROUND

With improved survival rates in critical care, increasing focus is being placed on survivorship and how best to support patients in returning to their former activity. Little is known about what support patients themselves view as important, and this has implications for the efficacy and acceptability of services provided.

OBJECTIVES

To describe former critical care patients' perspectives on the support needed to optimize recovery.

STUDY DESIGN

This is a qualitative exploratory study of the experiences of support received by critical care survivors.

RESEARCH METHODOLOGY

Semi-structured interviews were undertaken with 12 critical care survivors recruited from a charity and a patient and public involvement group. The interviews were analysed using thematic analysis to describe patterns in the participants' experiences.

FINDINGS

Four themes of support were described: effective management of transfer anxiety, tailored information provision, timely access to services and a supportive social network.

CONCLUSION

Survivors of critical care should be equipped with information about their critical care stay, ongoing health issues and recovery and should be provided with holistic care at home. Critical care follow up was an effective way of meeting many of these needs, but this needs to be flexible to be useful to attendees. Peer support groups (face-to-face and online) provided information, reassurance, a social network and an avenue for those who had longer-lasting problems than current services provide for.

RELEVANCE TO CLINICAL PRACTICE

Whilst there are commonalities in the problems faced by critical care survivors, recovery is highly individualized, and current support services do not have sufficient flexibility to cater for this. This study shows that many survivors experience after-effects of critical care that outlast the support they are given. These longer-term survivors are often excluded from research studies because of fears of recall bias, resulting in poor understanding of their experiences.

Caring for the Caregiver: Identifying the Needs of Those Called to Care Through Partnerships with Congregations

As the older adult population continues to grow, the prevalence of chronic diseases is also increasing, leading to the need for novel ways of managing this large population of patients. One solution is to focus on informal caregivers. These informal caregivers already make a substantial contribution to our nation's healthcare finances and patient health outcomes. Caregivers also derive benefits from caring for their family member or friend; however, it is not uncommon for these individuals to experience negative health consequences, or what is often called "burden of care." Those called to care are not without their own burdens, and they must frequently make significant lifestyle adjustments that impact their own health. Therefore, for caregivers to be effective, caring for the caregivers must be a focus of medicine in the twenty-first century.

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.

Effects of Resourcefulness on Sleep Disturbances, Anxiety, and Depressive symptoms in Family Members of Intensive Care Unit Patients

The study aimed to investigate the relationships among psychological distresses, resourcefulness, sleep disturbances, anxiety and depressive symptoms in family members of intensive care unit (ICU) patients. A cross-sectional, descriptive correlational design was employed. Using structural equation modeling (SEM) approach, relationships among factors, mediators, and outcomes were analyzed. The SEM explained 59% of the variances in depressive symptoms and 36% in anxiety. Family members with greater learned resourcefulness had fewer sleep disturbances, depressive and anxiety symptoms. Nursing professionals need to detect psychiatric disease of family members and must be especially vigilant with people who have low resourcefulness and sleep disturbances.

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.).

Recovery and outcomes after the acute respiratory distress syndrome (ARDS) in patients and their family caregivers

Outcomes after acute respiratory distress syndrome (ARDS) are similar to those of other survivors of critical illness and largely affect the nerve, muscle, and central nervous system but also include a constellation of varied physical devastations ranging from contractures and frozen joints to tooth loss and cosmesis. Compromised quality of life is related to a spectrum of impairment of physical, social, emotional, and neurocognitive function and to a much lesser extent discrete pulmonary disability. Intensive care unit-acquired weakness (ICUAW) is ubiquitous and includes contributions from both critical illness polyneuropathy and myopathy, and recovery from these lesions may be incomplete at 5 years after ICU discharge. Cognitive impairment in ARDS survivors ranges from 70 to 100 % at hospital discharge, 46 to 80 % at 1 year, and 20 % at 5 years, and mood disorders including depression and post-traumatic stress disorder (PTSD) are also sustained and prevalent. Robust multidisciplinary and longitudinal interventions that improve these outcomes are still uncertain and data in our literature are conflicting. Studies are needed in family members of ARDS survivors to better understand long-term outcomes of the post-ICU family syndrome and to evaluate how it affects patient recovery.

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.

A feasibility and pilot randomized controlled trial of the “Timing it Right Stroke Family Support Program”

Objective:

Examine feasibility of conducting a randomized controlled trial of the Timing it Right Stroke Family Support Program (TIRSFSP) and collect pilot data.

Design:

Multi-site mixed method randomized controlled trial.

Setting:

Acute and community care in three Canadian cities.

Subjects:

Caregivers were family members or friends providing care to individuals who experienced their first stroke.

Intervention:

The TIRSFSP offered in two formats, self-directed by the caregiver or stroke support person-directed over time, were compared to standard care.

Main measures:

Caregivers completed baseline and follow-up measures 1, 3 and 6 months post-stroke including Centre for Epidemiological Studies Depression, Positive Affect, Social Support, and Mastery Scales. We completed in-depth qualitative interviews with caregivers and maintained intervention records describing support provided to each caregiver.

Results:

Thirty-one caregivers received standard care ( n=10), self-directed ( n=10), or stroke support person-directed ( n=11) interventions. We retained 77% of the sample through 6-months. Key areas of support derived from intervention records ( n=11) related to caregiver wellbeing, caregiving strategies, patient wellbeing, community re-integration, and service delivery. Compared to standard care, caregivers receiving the stroke support person-directed intervention reported improvements in perceived support (estimate 3.1, P=.04) and mastery (estimate .35, P=.06). Qualitative caregiver interviews ( n=19) reflected the complex interaction between caregiver needs, preferences and available options when reporting on level of satisfaction.

Conclusions:

Preliminary findings suggest the research design is feasible, caregivers’ needs are complex, and the support intervention may enhance caregivers’ perceived support and mastery. The intervention will be tested further in a large scale trial.

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.

Impact of children's feeding/swallowing problems: validation of a new caregiver instrument

The impact of caring for children with deglutition disorders is poorly understood and tools to measure the unique concerns of these caregivers are lacking. The aims of this investigation were to develop and validate The Feeding/Swallowing Impact Survey (FS-IS) as an instrument designed to measure and improve understanding of caregiver issues. Demographic, economic, and dysphagic data were provided by the primary caregivers of 164 children (median age: 14 months, male: 78, female: 86) presenting for initial outpatient feeding/swallowing evaluations. Caregivers completed the PEDS-QL™ Family Impact Module (PEDS-QL™ FIM) and the FS-IS. A principal component analysis was conducted on the FS-IS to identify appropriate subscales. Concurrent validity was assessed by examining correlations between the FS-IS and PEDS-QL™ FIM. Caring for children with feeding/swallowing problems adversely impacted the Health-Related Quality of Life (HRQoL) of their caregivers. The FS-IS had a strong 3-factor solution to indicate 3 subscales: Daily Activities, Worry, and Feeding Difficulties. All three subscales and total score of the FS-IS correlated with PEDS-QL™ FIM. The FS-IS was validated as an instrument that may help clinicians detect specific factors that influence caregiver HRQoL, identify caregivers who might benefit from additional support, and ultimately improve the care of their children with feeding/swallowing disorders.

What Makes Family Caregivers Happy During the First 2 Years Post Stroke?

Background and Purpose—

This study aimed to identify aspects of the caregiving situation contributing to family caregivers’ psychological well-being.

Methods—

Longitudinal cohort study with structured quantitative interviews 1, 3, 6, and 12 months post stroke. A subset of participants also completed surveys 18 and 24 months post stroke. Participants included individuals hospitalized for their first stroke and their family caregivers. Psychological well-being was assessed by the Positive Affect Scale.

Results—

A total of 399 stroke survivor, caregiver dyads completed the 1-year follow-up and 80 dyads completed the second year of follow-up. Using mixed effects modeling for longitudinal data, caregivers reported more psychological well-being when they provided more assistance to stroke survivors who had fewer symptoms of depression, better cognitive functioning, and who had more severe strokes. In addition, caregivers who maintained participation in valued activities had more mastery, gained personally providing care, were in better physical health, were older, and were from Quebec reported more psychological well-being. Caregivers followed for a second year post stroke reported better psychological well-being when caring for stroke survivors with fewer symptoms of depression and more severe strokes and when the caregivers had a greater sense of mastery and gained more personally providing care.

Conclusions—

Our findings contribute to the caregiver intervention development literature by identifying aspects of the caregiving situation that are associated with positive outcomes. Incorporating specific aspects, for example, strategies to enhance caregiver mastery into programs and services offered to caregivers may enhance their positive experiences with providing care and ultimately enhance the sustainability of the caregiving situation.

Randomized clinical trial of the Timing it Right Stroke Family Support Program: research protocol

BACKGROUND

Family caregivers provide invaluable support to stroke survivors during their recovery, rehabilitation, and community re-integration. Unfortunately, it is not standard clinical practice to prepare and support caregivers in this role and, as a result, many experience stress and poor health that can compromise stroke survivor recovery and threaten the sustainability of keeping the stroke survivor at home. We developed the Timing it Right Stroke Family Support Program (TIRSFSP) to guide the timing of delivering specific types of education and support to meet caregivers' evolving needs. The objective of this multi-site randomized controlled trial is to determine if delivering the TIRSFSP across the stroke care continuum improves caregivers' sense of being supported and emotional well-being.

METHODS/DESIGN

Our multi-site single-blinded randomized controlled trial will recruit 300 family caregivers of stroke survivors from urban and rural acute care hospitals. After completing a baseline assessment, participants will be randomly allocated to one of three groups: 1) TIRSFSP guided by a stroke support person (health care professional with stroke care experience), delivered in-person during acute care and by telephone for approximately the first six to 12 months post-stroke, 2) caregiver self-directed TIRSFSP with an initial introduction to the program by a stroke support person, or 3) standard care receiving the educational resource "Let's Talk about Stroke" prepared by the Heart and Stroke Foundation. Participants will complete three follow-up quantitative assessments 3, 6, and 12-months post-stroke. These include assessments of depression, social support, psychological well-being, stroke knowledge, mastery (sense of control over life), caregiving assistance provided, caregiving impact on everyday life, and indicators of stroke severity and disability. Qualitative methods will also be used to obtain information about caregivers' experiences with the education and support received and the impact on caregivers' perception of being supported and emotional well-being.

DISCUSSION

This research will determine if the TIRSFSP benefits family caregivers by improving their perception of being supported and emotional well-being. If proven effective, it could be recommended as a model of stroke family education and support that meets the Canadian Stroke Best Practice Guideline recommendation for providing timely education and support to families through transitions.

Rehabilitation activities, out-patient visits and employment in patients and partners the first year after ICU: a descriptive study

OBJECTIVES

To describe the influence of critical illness on patients and their partners in relation to rehabilitation, healthcare consumption and employment during the first year after Intensive Care Unit discharge.

DESIGN

Longitudinal, observational and descriptive.

SETTING

Five Danish Intensive Care Units.

METHODS

Data were collected from hospital charts, population registers and interviews with 18 patients and their partners at 3 and 12 months after intensive care discharge. Descriptive statistical analysis was performed.

RESULTS

Post-discharge inpatient rehabilitation was median (range) 52 (15-174) days (n=10). Community-based training was 12 (3-34) weeks (n=15). Neuropsychological rehabilitation following brain damage was 13-20 weeks (n=3). Number of out-patient visits 1 year before and 1 year after were mean 3 versus 8, and General Practitioner visits were 12 versus 18. Three patients resumed work at pre-hospitalisation employment rates after 12 months. After the patients' stay in intensive care, partners' mean full-time sick leave was 17 (range 0-124) days and 21 (range 0-106) days part time. Partners often had long commutes.

CONCLUSION

Most patients had comprehensive recovery needs requiring months of rehabilitation. Some partners needed extensive sick leave. The study reveals the human cost of critical illness and intensive care for patients and partners in the Danish welfare system.

Sepsis after Scotland: enough with the averages, show us the effect modifiers

Cuthbertson and colleagues demonstrate that survivors of severe sepsis face, in general continued ongoing high mortality and quite poor quality of life. This cohort caps the initial, problem-definition stage on long-term outcomes after critical illness. Having compellingly demonstrated the opportunities for improvements in outcomes, epidemiologic and behavioral research must now to turn to understanding the mechanisms by which these outcomes can be improved. Such fundamental research will provide the evidence base to drive informed and successful interventional trials.
