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

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.

Long-Term Psychological Distress Among Surrogate Decision Makers for Mexican American and Non-Hispanic White Patients With Severe Stroke

BACKGROUND AND OBJECTIVES

During acute hospitalizations, physicians often focus on the stroke patient and not family who may be traumatized by this sudden change to their loved one. We investigated long-term psychological distress among family surrogate decision makers for Mexican American (MA) and non-Hispanic White (NHW) severe stroke patients. Previous work in other diseases suggested worse psychological outcomes in MA than NHW caregivers.

METHODS

This was a population-based, prospective cohort study in Nueces County, TX. Stroke patient participants and their surrogate decision makers were enrolled soon after any stroke between April, 2016, and October, 2020, if surrogates had made decisions about life-sustaining treatments. Surrogates completed validated measures of posttraumatic stress, National Stressful Events Survey for Posttraumatic Stress Disorder Short Scale; anxiety, Generalized Anxiety Disorder-7; and depression, Patient Health Questionnaire-8 at discharge, 3, 6, and 12 months. Ethnic differences were assessed with multilevel linear mixed models, sequentially adjusted for prespecified patient and surrogate demographic, socioeconomic, and clinical covariates.

RESULTS

There were 301 family surrogates for 241 severe stroke patients. The mean follow-up was 315 days. High scores on measures of psychological distress ranged between 17% and 28% of surrogates. One or more high levels of the psychological outcomes were found in 17%-43% of surrogates; 2 or more were found in 12%-27%; and all 3 were found in 5%-16% of surrogates. All psychological outcomes were worse among MAs on unadjusted analyses. In fully adjusted models, posttraumatic stress remained worse among MAs (0.36, 95% CI 0.17-0.56); ethnic differences were attenuated and no longer significant in the final model for anxiety (0.59, 95% CI -0.55 to 1.74) and depression (0.97, 95% CI -0.25 to 2.19). The trajectory for depression did differ by ethnicity (interaction p = 0.03), with depression score improving more rapidly over time among NHWs than MAs. Advance care plans did not seem to confound any ethnic differences.

DISCUSSION

Psychological distress is common among family surrogate decision makers in the year after stroke and may be worse among MAs. Efforts are needed to support family members of all ethnic groups after severe stroke.

Decision Self-Efficacy and Decisional Conflict on Reintubation among Surrogates of Ventilated Patients Undergoing Planned Extubation

PURPOSE

Although the medical decision-making process can be overwhelming for some surrogates, there is a lack of understanding regarding their experiences. The objectives of this study were to examine the decision self-efficacy and decisional conflict experienced by surrogates in intensive care units (ICUs) when faced with the decision of whether to reintubate patients with respiratory failure after a planned extubation. In addition, predictors and mediators influencing these decision-making processes were identified.

METHODS

This study utilized a cross-sectional design to investigate the decision-making processes of 174 surrogates who were faced with the decision of whether to reintubate patients with respiratory failure after a planned extubation in the internal ICU of a medical center between August 2021 and February 2022. Structured questionnaires were administered to collect data on the surrogates' background information, decision self-efficacy, decisional conflict, and positive and negative affect. The patients' background information was also collected. Univariate and multivariate analyses were performed to model the data.

RESULTS

The mean decision self-efficacy score of the surrogates was 82.41 points, and 20.7% surrogates had decisional conflict scores exceeding 37.5 points, suggesting that they faced challenges in the decision-making process. Surrogates' employment status and negative affect significantly predicted their decision self-efficacy. In addition, patients' activities of daily living prior to hospitalization and the decision self-efficacy of the surrogate significantly predicted surrogate decisional conflict. The impact of surrogates' negative affect on decisional conflict was fully mediated by decision self-efficacy.

CONCLUSIONS

Surrogate decision self-efficacy mediates the relationship between negative affect and decisional conflict. Providing clinical care interventions that focus on enhancing surrogate self-efficacy and reducing negative affect can help alleviate decisional conflict in this population.

Associations between Latino ethnicity and the use of emotional support and completion of advance directives

OBJECTIVES

Latino patients have been shown to engage in advance care planning (ACP) at much lower rates than non-Latino White patients. Coping strategies, such as the use of emotional support, may differentially relate to engagement in ACP among Latino and non-Latino patients. The present study sought to examine the moderating effect of ethnicity on the relationship between the use of emotional support as a coping strategy and completion of advance directives.

METHODS

The present study employed a weighted sample (Nw = 185) of Latino and non-Latino White patient participants in Coping with Cancer III, an National Institutes of Health-sponsored, multisite, longitudinal, observational cohort study of patients with advanced cancer and their informal caregivers and oncology providers designed to evaluate Latino/non-Latino disparities in ACP and end-of-life cancer care. Main and interaction effects of Latino ethnicity and use of emotional support on patient use of advance directives were estimated as odds ratios.

RESULTS

Use of emotional support was associated with dramatically lower do-not-resuscitate (DNR) order completion to a greater extent among Latino as compared to non-Latino patients (interaction AOR = 0.33, p = 0.005). Interaction effects were not statistically significant for living will or health-care proxy form completion.

SIGNIFICANCE OF RESULTS

Use of emotional support is associated with lower odds of completing DNRs among Latino than among non-Latino patients. Seeking and/or receiving emotional support may deter Latino patients from completing DNR orders. Research is needed to address both emotional needs and practicalities to ensure high quality end-of-life care among Latino patients with cancer.

A Mixed-Methods Feasibility Study: Eliciting ICU Experiences and Measuring Outcomes of Family Caregivers of Patients Who Have Undergone Hematopoietic Stem Cell Transplantation

The impact of an intensive care unit (ICU) admission on family caregivers of patients who have undergone hematopoietic stem cell transplantation (HSCT) has not been well described. Aims of this study were to determine the feasibility of conducting research with family caregivers of HSCT patients during an ICU admission and generate preliminary data about their experiences and engagement in care. Using a mixed-methods, repeated measures design, we collected data from family caregivers after 48 hr in the ICU (T1) and at 48 hr after transferring out of ICU (T2). Enrolling HSCT caregivers in research while in the ICU was feasible (10/13 consented; 9/10 completed data collection at T1); however, data collection at T2 was not possible for most caregivers. Caregiver distress levels were high, and engagement in care was moderate. The three themes that emerged from interviews (n = 5) highlighted that although HSCT family caregivers faced many challenges and received limited support during their ICU experience, they were able to access their own personal resources and demonstrated resilience.

Associations of surrogates' death-preparedness states with decisional conflict and heightened decisional regret over cancer patients' last 6 months of life

OBJECTIVE

Preparing family surrogates for patient death and end-of-life (EOL) decision making may reduce surrogate decisional conflict and regret. Preparedness for patient death involves cognitive and emotional preparedness. We assessed the associations of surrogates' death-preparedness states (that integrate both cognitive and emotional preparedness for patient death) with surrogates' decisional conflict and regret.

METHODS

Associations of 173 surrogates' death-preparedness states (no, cognitive-only, emotional-only, and sufficient preparedness states) with decisional conflict (measured by the Decision Conflict Scale) and heightened decisional regret (Decision Regret Scale scores >25) were evaluated using hierarchical linear modeling and hierarchical generalized linear modeling, respectively, during a longitudinal observational study at a medical center over cancer patients' last 6 months.

RESULTS

Surrogates reported high decisional conflict (mean [standard deviation] = 41.48 [6.05]), and 52.7% of assessments exceeded the threshold for heightened decisional regret. Surrogates in the cognitive-only preparedness state reported a significantly higher level of decisional conflict (β = 3.010 [95% CI = 1.124, 4.896]) than those in the sufficient preparedness state. Surrogates in the no (adjusted odds ratio [AOR] [95% CI] = 0.293 [0.113, 0.733]) and emotional-only (AOR [95% CI] = 0.359 [0.149, 0.866]) preparedness states were less likely to suffer heightened decisional regret than those in the sufficient preparedness state.

CONCLUSIONS

Surrogates' decisional conflict and heightened decisional regret are associated with their death-preparedness states. Improving emotional preparedness for the patient's death among surrogates in the cognitive-only preparedness state and meeting the specific needs of those in the no, emotional-only, and sufficient preparedness states are actionable high-quality EOL-care interventions that may lessen decisional conflict and decisional regret.

Quality indicators of palliative care for cardiovascular intensive care

Healthcare providers working for cardiovascular intensive care often face challenges and they play an essential role in palliative care and end-of-life care because of the high mortality rates in the cardiac intensive care unit. Unfortunately, there are several barriers to integrating palliative care, cardiovascular care, and intensive care. The main reasons are as follows: cardiovascular disease-specific trajectories differ from cancer, there is uncertainty associated with treatments and diagnoses, aggressive treatments are necessary for symptom relief, and there is ethical dilemma regarding withholding and withdrawal of life-sustaining therapy. Quality indicators that can iterate the minimum requirements of each medical discipline could be used to overcome these barriers and effectively practice palliative care in cardiovascular intensive care. Unfortunately, there are no specific quality indicators for palliative care in cardiovascular intensive care. A few indicators and their domains are useful for understanding current palliative care in cardiovascular intensive care. Among them, several domains, such as symptom palliation, patient- and family-centered decision-making, continuity of care, and support for health care providers that are particularly important in cardiovascular intensive care.

Historically, the motivation for using quality indicators is to summarize mechanisms for external accountability and verification, and formative mechanisms for quality improvement. Practically, when using quality indicators, it is necessary to check structural indicators in each healthcare service line, screen palliative care at the first visit, and integrate palliative care teams with other professionals. Finally, we would like to state that quality indicators in cardiovascular intensive care could be useful as an educational tool for practicing palliative care, understanding the minimum requirements, and as a basic structure for future discussions.
