Psychological Symptoms Among Surrogates of Critically Ill Patients During and Before the COVID-19 Pandemic

Understanding Intensive Care Unit Family Caregivers' Vulnerability to Post-Traumatic Stress Disorder: The Impact of Neurotic Personality Traits, Emotional Suppression, and Perceptions of Unexpected Death

Rationale: Family members of patients who die in an intensive care unit (ICU) are at heightened risk of post-traumatic stress disorder (PTSD) symptoms. Not all surrogates develop these symptoms and heterogeneity exists in PTSD symptom clusters. Objectives: The study tested a personality model of PTSD symptoms in bereaved family caregivers of ICU patients. It was hypothesized that family members endorsing higher levels of neurotic personality traits would report higher levels of PTSD symptom clusters and that these associations would be explained by tendencies to view the patient's death as unexpected and to cope by suppressing their emotions. Methods: Participants were family members of ICU patients at an urban, academic medical center who either died or were discharged to an inpatient hospice unit. Participants were contacted for participation at least six months after the patient's death. Participants completed measures of personality, emotion regulation, and PTSD symptoms. Data were analyzed using path analysis. Results: Approximately one-third (35%) of the sample of 162 caregivers endorsed at-risk levels of PTSD. Individuals reporting higher levels of neurotic personality traits reported more PTSD symptoms (r = 0.53, p < 0.001). Perceptions that the patient death was unexpected partially explained the association of neuroticism with the intrusive re-experiencing PTSD symptoms (B = 0.45, p = 0.031). In contrast, emotional suppression partially explained the association of neuroticism with avoidance (B = 0.70, p = 0.010) and hyperarousal symptom clusters (B = 0.37, p = 0.041). Conclusions: Family vulnerability to PTSD after an ICU death can be conceptualized based on neurotic personality traits. Tendencies to view the patient's death as unexpected may contribute to intrusive thoughts and memories of the ICU experience. Individuals may avoid reminders and remain at heightened levels of arousal when they suppress their emotional experiences. Key Message: Family members who experience the death of a loved one following ICU treatment are vulnerable to PTSD symptoms. These reactions to ICU-related losses may be shaped by family members' personalities, expectations, and emotion regulation styles. Understanding these characteristics could inform family screening and intervention efforts in the ICU.

The Stresses of Surrogate Decision-Making: Contributing Factors and Clinicians' Role in Mitigation

BACKGROUND

Surrogate Decision-Makers (surrogates) are frequently employed in decision-making for critically ill adults. There are insufficient data considering the surrogate experience, stress, and potential for mitigation.

METHODS

An anonymous online survey queried (1) medical situation (2) total stress (3) demographics (4) potential factors, including sources of information about patient wishes, external sources of support or competing stressors, and their interactions with the medical team through the experience.

RESULTS

108 respondents were included; 91 completed all items. Most respondents ranked their experience as a surrogate as one of the most stressful experiences of their lives; this was associated with whether it was an end-of-life decision (P = .003), Respondent Religion (P = .015), or religious or spiritual beliefs (P = .024), and having their own health problems (P = .008). On individual Likert responses, surrogates reported significant stress mitigation when they felt they had been helpful (P < .001), knew the patient's wishes (P = .0011), specifically discussed patient wishes (P < .001), or patient's wishes were documented (P < .001). Items about surrogate-team interaction also met significance, including the physician being communicative and available (P < .001), respectful (P = .007), honest (P < .001), and validating (P = .001).

CONCLUSIONS

Surrogate stress is an evolving area for research. Significant factors included relationship with the medical team, making this an important area for HPM to play a key role in mitigating surrogate stress.

EMPOWER: A Multi-Site Pilot Trial to Reduce Distress in Surrogate Decision-Makers in the ICU

CONTEXT

Efforts to reduce the psychological distress of surrogate decision-makers of critically ill patients have had limited success, and some have even exacerbated distress.

OBJECTIVES

The aim of this study was to determine the feasibility, acceptability, and preliminary efficacy of EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), an ultra-brief (∼2-hour), 6-module manualized psychological intervention for surrogates.

METHODS

Surrogates who reported significant anxiety and/or an emotionally close relationship with the patient (n=60) were randomized to receive EMPOWER or enhanced usual care (EUC) at one of three metropolitan hospitals. Participants completed evaluations of EMPOWER's acceptability and measures of psychological distress pre-intervention, immediately post-intervention, and at 1- and 3-month follow-up assessments.

RESULTS

Delivery of EMPOWER appeared feasible, with 89% of participants completing all 6 modules, and acceptable, with high ratings of satisfaction (mean=4.5/5, SD = .90). Compared to EUC, intent-to-treat analyses showed EMPOWER was superior at reducing peritraumatic distress (Cohen's d = -0.21, small effect) immediately post-intervention and grief intensity (d = -0.70, medium-large effect), posttraumatic stress (d = -0.74, medium-large effect), experiential avoidance (d = -0.46, medium effect), and depression (d = -0.34, small effect) 3 months post-intervention. Surrogate satisfaction with overall critical care (d = 0.27, small effect) was higher among surrogates randomized to EMPOWER.

CONCLUSIONS

EMPOWER appeared feasible and acceptable, increased surrogates' satisfaction with critical care, and prevented escalation of posttraumatic stress, grief, and depression 3 months later.

Written Communication, Visitation Policies, and Awareness of Medical Issues Among Intensive Care Unit Families

BACKGROUND

Open intensive care unit (ICU) visitation policies facilitate communication between clinicians and patients' families. Restrictive visitation policies (eg, during a pandemic) may reduce families' comprehension of information.

OBJECTIVES

To determine whether written communication increased awareness of medical issues among ICU families and whether the effect size depended on the visitation policies in place when participants were enrolled.

METHODS

Families of ICU patients were randomly assigned to receive usual care with or without daily written patient care updates from June 2019 to January 2021. Participants were asked whether patients had experienced 6 ICU problems at up to 2 time points during the ICU stay. Responses were compared with the study investigators' consensus.

RESULTS

Of 219 participants, 131 (60%) were restricted from visiting. Participants in the written communication group were more likely than participants in the control group to correctly identify shock, renal failure, and weakness and were just as likely as participants in the control group to correctly identify respiratory failure, encephalopathy, and liver failure. Participants in the written communication group were more likely than participants in the control group to correctly identify the patient's ICU problems when all 6 were grouped as a composite outcome, with the adjusted odds ratio of correct identification tending to be higher among participants enrolled during restricted versus open visitation periods: 2.9 (95% CI, 1.9-4.2; P < .001) vs 1.8 (95% CI, 1.1-3.1; P = .02), P = .17 for difference.

CONCLUSIONS

Written communication helps families correctly identify ICU issues. The benefit may be enhanced when families cannot visit the hospital. ClinicalTrials.gov Identifier: NCT03969810.

Piloting Group-Based Behavioral Activation Therapy for Families of Deceased COVID-19 Patients

Surrogate decision-making is a stressful process for many family members of critically ill patients. The COVID-19 pandemic may have amplified the risk for anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms in ICU surrogates.

OBJECTIVES

This study piloted an online group-based behavioral intervention with family members of deceased COVID-19 patients. Participant engagement, perceptions, and responses related to the intervention were assessed.

DESIGN

A single-arm pilot study was conducted with bereaved families. Quantitative analysis of measures of anxiety, depression, and PTSD symptoms was conducted with mixed models. Qualitative data were analyzed to identify themes in surrogates' experiences with the intervention.

SETTING

Participants were recruited from ICUs at a tertiary academic medical center. Participants completed the intervention, measures, and interviews online.

SUBJECTS

Participants were family members of patients who died from COVID-19.

INTERVENTIONS

The intervention involved six online group-based behavioral activation sessions. Sessions covered topics pertinent to grieving and engagement in personally meaningful activities.

MEASUREMENTS AND MAIN RESULTS

Semi-structured interviews explored participants' experiences with the intervention. Surrogates also completed measures of anxiety, depression, and PTSD symptoms before and after the intervention. Nineteen of 26 participants (73.1%) completed the study. Thematic analysis suggested that surrogates found the group helpful for overcoming perceived isolation, receiving validation, and developing coping skills. Significant pre-to-post reductions were observed in symptoms of Hospital and Anxiety Disorder Scale (HADS) anxiety (pre-mean = 9.27, sd = 5.30 vs post-mean = 6.80, sd = 4.16; p = 0.0271), HADS depression (pre-mean =6 .65, sd = 4.58 vs post- mean = 4.89, sd = 3.40; p = 0.0436), and Impact of Events Scale-Revised PTSD (pre-mean = 36.86, sd = 16.97 vs post-mean = 24.14, sd = 13.49; p = 0.0008).

LIMITATIONS

This was a preliminary study based on qualitative and self-report measures. Future studies should include a control group.

CONCLUSIONS

Online group-based behavioral activation therapy appears to be a potentially useful intervention for family members of ICU patients who died from COVID-19.

Patients' and caregivers' experiences of hospitalization under COVID-19 visitation restrictions

BACKGROUND

During the COVID-19 pandemic, hospitals did not allow caregiver visitation. Little is known about how caregivers' absence affected patients' care.

OBJECTIVE

This study aimed to describe visitation restrictions' impact on patients and their caregivers experiences.

DESIGN

We used a sequential explanatory mixed-methods study design. First, we randomly selected 200 adult patients with cancer or heart failure hospitalized before (n = 100) and during visitor restrictions (n = 100) and abstracted data from the electronic medical record on communication between medical teams and caregivers and the topics discussed. Results from the quantitative analysis guided our thematic analysis of semi-structured interviews conducted with a subsample of patients hospitalized during visitor restrictions and their caregivers to understand the impact of visitor restrictions on their experiences.

RESULTS

Compared to prerestrictions, caregivers under visitation restrictions communicated less frequently with the medical team (29% vs. 37% of hospitalized days; p = .04), fewer received discharge counseling (37% vs. 52%; p = .04), and disproportionately more had no contact with the medical team (36% vs. 17%; p < .01). Video conferencing was documented for caregivers of only five patients. Qualitative analysis revealed that both caregivers and patients experienced emotional distress, increased conflict, and decreased perception of quality of care because of visitation restrictions.

CONCLUSIONS

Hospital visitor restrictions significantly reduced caregivers' communication with patients' medical team, causing caregivers and patients emotional distress. Protocols that facilitate communication between caregivers and care teams may benefit caregivers who cannot be physically present at care facilities, including distance caregivers.

Stress-Related Disorders of Family Members of Patients Admitted to the Intensive Care Unit With COVID-19

IMPORTANCE

The psychological symptoms associated with having a family member admitted to the intensive care unit (ICU) during the COVID-19 pandemic are not well defined.

OBJECTIVE

To examine the prevalence of symptoms of stress-related disorders, primarily posttraumatic stress disorder (PTSD), in family members of patients admitted to the ICU with COVID-19 approximately 90 days after admission.

DESIGN, SETTING, AND PARTICIPANTS

This prospective, multisite, mixed-methods observational cohort study assessed 330 family members of patients admitted to the ICU (except in New York City, which had a random sample of 25% of all admitted patients per month) between February 1 and July 31, 2020, at 8 academic-affiliated and 4 community-based hospitals in 5 US states.

EXPOSURE

Having a family member in the ICU with COVID-19.

MAIN OUTCOMES AND MEASURES

Symptoms of PTSD at 3 months, as defined by a score of 10 or higher on the Impact of Events Scale 6 (IES-6).

RESULTS

A total of 330 participants (mean [SD] age, 51.2 [15.1] years; 228 [69.1%] women; 150 [52.8%] White; 92 [29.8%] Hispanic) were surveyed at the 3-month time point. Most individuals were the patients' child (129 [40.6%]) or spouse or partner (81 [25.5%]). The mean (SD) IES-6 score at 3 months was 11.9 (6.1), with 201 of 316 respondents (63.6%) having scores of 10 or higher, indicating significant symptoms of PTSD. Female participants had an adjusted mean IES-6 score of 2.6 points higher (95% CI, 1.4-3.8; P < .001) than male participants, whereas Hispanic participants scored a mean of 2.7 points higher compared with non-Hispanic participants (95% CI, 1.0-4.3; P = .002). Those with graduate school experience had an adjusted mean score of 3.3 points lower (95% CI, 1.5-5.1; P < .001) compared with those with up to a high school degree or equivalent. Qualitative analyses found no substantive differences in the emotional or communication-related experiences between those with high vs low PTSD scores, but those with higher scores exhibited more distrust of practitioners.

CONCLUSIONS AND RELEVANCE

In this cohort study, symptoms of PTSD among family members of ICU patients with COVID-19 were high. Hispanic ethnicity and female gender were associated with higher symptoms. Those with higher scores reported more distrust of practitioners.

Daily Written Care Summaries for Families of Critically Ill Patients: A Randomized Controlled Trial

OBJECTIVES

To determine the effect of daily written updates on the satisfaction and psychologic symptoms of families of ICU patients.

DESIGN

Randomized controlled trial.

SETTING

Single, urban academic medical center.

SUBJECTS

Surrogates of nondecisional, critically ill adults with high risk of mortality (n = 252) enrolled from June 2019 to January 2021.

INTERVENTIONS

Usual communication with the medical team with or without written communication detailing the suspected cause and management approach of each ICU problem, updated each day.

MEASUREMENTS AND MAIN RESULTS

Participants completed surveys at three time points during the ICU stay: enrollment (n = 252), 1 week (n = 229), and 2 weeks (n = 109) after enrollment. Satisfaction with care was measured using the Critical Care Family Needs Inventory (CCFNI). The presence of anxiety, depression, and acute stress were assessed using the Hospital Anxiety and Depression Scale (HADS) and Impact of Events Scale Revised (IES-R). CCFNI, HADS, and IES-R scores were similar among participants assigned to the intervention group and control group upon enrollment and during the first week after enrollment (p > 0.05). From enrollment to the second week after enrollment, there was an improvement in CCFNI and HADS scores among participants assigned to the intervention group versus the control group. At week 2, CCFNI scores were significantly lower among participants in the intervention group versus the control group, indicating greater satisfaction with care: 15.1 (95% CI, 14.2-16.0) versus 16.4, (95% CI, 15.5-17.3); p = 0.04. In addition, 2 weeks after enrollment, the odds of symptoms of anxiety, depression, and acute stress among participants assigned to the intervention versus control group were 0.16 (95% CI, 0.03-0.82; p = 0.03); 0.15 (95% CI, 0.01-1.87; p = 0.14); and 0.27 (95% CI, 0.06-1.27; p = 0.10), respectively.

CONCLUSIONS

Written communication improved satisfaction and the emotional well-being of families of critically ill patients, supporting its use as a supplement to traditional communication approaches.

Challenges faced by families of critically ill patients during the first wave of the COVID-19 pandemic

OBJECTIVE

To understand how surrogates of critically ill patients adjusted to challenges that resulted from the COVID-19 pandemic.

METHODS

Participants (N = 62) were surrogates of critically ill adults with COVID-19 in the ICU at an urban, academic medical center from March to June 2020. Participants were recruited using convenience sampling and took part in one-time qualitative individual interviews via telephone. Qualitative data were analyzed using thematic content analysis.

RESULTS

Qualitative analyses yielded four types of challenges: Communication with the medical team, communication among family members, understanding and tracking medical information, and distress related to visitor restrictions. To adjust to challenges related to communication, participants developed routines for receiving updates from the medical team and providing updates to other family members. To adjust to the challenge related to comprehension, participants sought information from external sources such as family members in healthcare fields. To adjust to the challenge related to visitation, participants found some comfort in video calls with the patient.

CONCLUSIONS

Surrogates of critically ill patients with COVID-19 faced multiple types of challenges yet adjusted to those challenges.

PRACTICAL IMPLICATIONS

Future research should focus on ways to support the wellbeing of surrogates during times of restricted hospital visitation. Clinical trial registered at ClinicalTrials.gov (NCT03969810).

Family Presence for Critically Ill Patients During a Pandemic

Family engagement is a key component of high-quality critical care, with known benefits for patients, care teams, and family members themselves. The COVID-19 pandemic led to rapid enactment of prohibitions or restrictions on visitation that now persist, particularly for patients with COVID-19. Reevaluation of these policies in response to advances in knowledge and resources since the early pandemic is critical because COVID-19 will continue to be a public health threat for months to years, and future pandemics are likely. This article reviews rationales and evidence for restricting or permitting family members' physical presence and provides broad guidance for health care systems to develop and implement policies that maximize benefit and minimize risk of family visitation during COVID-19 and future similar public health crises.

Development and preliminary evaluation of EMPOWER for surrogate decision-makers of critically ill patients

OBJECTIVE

The objectives of this study were to develop and refine EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), a brief manualized cognitive-behavioral, acceptance-based intervention for surrogate decision-makers of critically ill patients and to evaluate its preliminary feasibility, acceptability, and promise in improving surrogates' mental health and patient outcomes.

METHOD

Part 1 involved obtaining qualitative stakeholder feedback from 5 bereaved surrogates and 10 critical care and mental health clinicians. Stakeholders were provided with the manual and prompted for feedback on its content, format, and language. Feedback was organized and incorporated into the manual, which was then re-circulated until consensus. In Part 2, surrogates of critically ill patients admitted to an intensive care unit (ICU) reporting moderate anxiety or close attachment were enrolled in an open trial of EMPOWER. Surrogates completed six, 15-20 min modules, totaling 1.5-2 h. Surrogates were administered measures of peritraumatic distress, experiential avoidance, prolonged grief, distress tolerance, anxiety, and depression at pre-intervention, post-intervention, and at 1-month and 3-month follow-up assessments.

RESULTS

Part 1 resulted in changes to the EMPOWER manual, including reducing jargon, improving navigability, making EMPOWER applicable for a range of illness scenarios, rearranging the modules, and adding further instructions and psychoeducation. Part 2 findings suggested that EMPOWER is feasible, with 100% of participants completing all modules. The acceptability of EMPOWER appeared strong, with high ratings of effectiveness and helpfulness (M = 8/10). Results showed immediate post-intervention improvements in anxiety (d = -0.41), peritraumatic distress (d = -0.24), and experiential avoidance (d = -0.23). At the 3-month follow-up assessments, surrogates exhibited improvements in prolonged grief symptoms (d = -0.94), depression (d = -0.23), anxiety (d = -0.29), and experiential avoidance (d = -0.30).

SIGNIFICANCE OF RESULTS

Preliminary data suggest that EMPOWER is feasible, acceptable, and associated with notable improvements in psychological symptoms among surrogates. Future research should examine EMPOWER with a larger sample in a randomized controlled trial.
