About this study
Intensive Care Units (ICU) are stressful places where life-and-death medical decisions are made and patients' surrogate decision-makers are exposed to potentially traumatic experiences. As the number of life-prolonging procedures administered to the patient rises, the patient's quality of life falls. Thus, interventions to improve the quality of life and care of ICU patients are needed.
EMPOWER is a cognitive-behavioral, acceptance-based intervention for patient surrogate decision-makers to reduce experiential avoidance of unpleasant thoughts and feelings related to thinking about patient death. By reducing surrogate's experiential avoidance, EMPOWER removes a barrier to advance care planning. EMPOWER aims to improve patient quality of life through enhancing value-directed end-of-life care while also empowering surrogates to cope with a loved one's potential impending death and adjust following the patient's ICU death or discharge. Specifically, investigators aim to:

- 1: Develop EMPOWER for surrogate decision-makers of critically ill patients who are at risk of becoming incapacitated or are currently unable to communicate in the ICU. Key informants, including bereaved ICU patient caregivers and clinicians, will be asked to evaluate the EMPOWER intervention manual to increase its potential tolerability, acceptability and efficacy.
- 2: Determine feasibility, tolerability, acceptability, and preliminary effects of EMPOWER on surrogate mental health.
- 3: Estimate the effects of EMPOWER on patient outcomes in the months following the ICU admission.
Hypothesis 1: Surrogate decision-makers who receive EMPOWER will have significantly lower levels of peritraumatic distress when compared to usual care condition at post intervention assessment (T2).
Hypothesis 2: Patients whose surrogates receive EMPOWER will have more value-concordant care, better quality of life, and better quality of death.
EMPOWER was first evaluated though a single site open trial (n=10). All 10 participants in the open trial phase received EMPOWER. Feedback from clinicians, bereaved stakeholders and results from the open trial were then used to refine the intervention and launch a multi-center randomized controlled trial to examine clinical superiority of EMPOWER to enhanced usual care. In order to adapt to restrictions in ICU visitation and meet the needs of family caregivers impacted by the COVID-19 pandemic, we then launched a second single arm open trial and paused recruitment for the RCT. All participants recruited during the open trial COVID-19 phase received EMPOWER. Beginning in August 2021, we resumed the RCT portion of the trial to meet the initial recruitment goals of the study (total n of RCT \& COVID-19 open trial=60).
Read the detailed description
Aggressive care in Intensive Care Units (ICUs) has been shown to impair the quality of life of patients with advanced cancer and to increase the risk of Posttraumatic Stress Disorder (PTSD) among the family and friends who serve as informal caregivers. Although ICU stays are established indicators of low quality end-of-life (EoL) cancer care, a large, growing number of cancer patients - over 1 in 4 -- are being admitted to the ICU in the last month of life. Even within the ICU, investigators find that as the number of life-prolonging procedures administered to the patient rises, the patient's quality of life falls. Thus, interventions to reduce the suffering and to improve the quality of life and care of ICU cancer patients are needed.
As described above, suffering is not confined to the patient. Informal caregivers of cancer patients in the ICU also suffer. In our "Severity of Suffering" (SoS) study, which examined dying cancer patients' quality of life in the ICU, nurses indicated that 53% of the patients' caregivers were acutely distressed. The nurses also reported that 43% of the patient's caregivers had unrealistic expectations for the patient's recovery and that 41% insisted that the patient receive futile, burdensome care (e.g., resuscitation). Over 85% of these patients were unable to communicate, which resulted in the need for grieving, potentially traumatized caregivers to serve as the patient's surrogate decision-maker and make life-and-death decisions for a critically ill, uncommunicative patient. Additionally, caregivers of patients who die in the ICU are also at elevated risk of posttraumatic stress disorder (PTSD) in the months that follow the potentially traumatic ICU "exposures". These findings indicate a compelling need to address the varying mental health needs of informal caregivers and surrogate decision-makers of patients in the ICU from admission to after discharge, as well as to provide them with resources to clarify and inform the decision-making process regarding care for patients who are unable to communicate.
To address these needs, we have developed and will refine and evaluate EMPOWER, a mental health intervention for surrogate decision-makers of ICU patients who are at risk of becoming incapacitated or are currently unable to make medical decisions. Delivered by a trained mental health professional in the ICU setting, EMPOWER is a cognitive-behavioral, acceptance-based intervention designed to reduce "experiential avoidance" of unpleasant thoughts and feelings related to thinking about the patient's death and to provide active strategies for coping with peritraumatic distress and anticipatory grief. Additionally, by reducing surrogates' experiential avoidance, EMPOWER removes a barrier to advanced care planning and promotes the receipt of EoL care consistent with patient values. In this way, EMPOWER aims to facilitate EoL care that enhances patient quality of life while also empowering surrogates to cope with a loved one's potential impending death and adjust following the patient's ICU death or discharge.
This study is designed to obtain information on its feasibility, tolerability, acceptability, and preliminary effect size estimates to inform the planning of a larger, efficacy randomized controlled trial (RCT). In order to develop the RCT, the first 10 surrogate decision-makers were enrolled in an open trial to receive EMPOWER. In addition, during the manual refinement phase, up to 15 stakeholders (bereaved caregivers of ICU patients) were interviewed after reviewing the EMPOWER intervention manual. We then began a pilot RCT, randomizing surrogate decision-makers to receive either EMPOWER or enhanced usual care using a block-randomization strategy to determine condition assignment. In light of restrictions on recruitment and increased needs of surrogates during the COVID-19 pandemic, we paused the RCT portion of this trial and we recruited for a second open trial only administering EMPOWER. 60 surrogate-patient dyads were enrolled between the RCT and COVID-19 open trial. In August 2021, we resumed the RCT trial of the study. We resumed in person recruitment and randomization of participants to EMPOWER or EUC. Including the first open trial, we will enroll a total of 70 surrogate decision-makers of 70 current patients from the intensive care units at New York Presbyterian-Weill Cornell, New York Presbyterian-Queens, and Memorial Sloan Kettering Cancer Center. Research staff will regularly contact ICU physicians in person or by email and/or screen patient charts to identify eligible candidates based on the inclusion criteria.
Surrogates will be consented and screened. Those who score above 5 on either item measuring anxiety in the McGill Quality of Life Scale, or with a summed score of at least 8 on the first two items of the Partner Dependency Scale (PDS) will be randomized to receive EMPOWER or usual care in the RCT, or solely assigned to receive the intervention in the pilot trials. Surrogates will be assessed pre-intervention/baseline (Time point 1, T1), post-intervention (within a week of the surrogate's completion of the baseline assessment) (Time point 2, T2), 1-month post-T2 (Time point 3, T3), and 3-months post-T2(Time point 4, T4). Surrogates will be assigned to either control (usual care) or intervention group using block randomization in the RCT, and solely to EMPOWER in open trials.
EMPOWER is based on well-established cognitive-behavioral techniques that aim to promote the expression and understanding of a person's emotional reactions. The EMPOWER interventionist will be compassionate and attempt to teach subjects tools for remaining present-focused, validate participants' experience, explore participants' loved ones' and participants' own wishes, values and decision challenges, increase subjects acceptance and sense of permission to experience challenging emotions, and prepare participants for future distressing situations. Enhanced usual care will consist of a surrogate's interactions with social support services in the ICU as documented in the patient's medical chart, referrals for current site-specific resources for informal caregivers, and a packet providing general information and tips on serving as an informal caregiver.
HLM modeling will determine differences between surrogates and patients assigned to EMPOWER vs. enhanced usual care. The primary outcome is post-intervention (T2) differences on a measure of peritraumatic distress. Secondary outcomes are differences on measures of prolonged grief disorder, PTSD and experiential avoidance at one-month (T3) and three-month (T4) follow up from T2. Exploratory outcomes for surrogates are differences in reported symptoms of anxiety, depression, and decision regret at one-month (T3) and three-month (T4) follow up from T2. Exploratory outcomes for patients are differences in surrogate-reported quality of life, quality of death, and value concordant care. HLM models will include covariates, either as fixed-effect or time-varying, if those variables are found to be significantly statistically associated with both intervention assignment and the outcome examined.
Following a review of the open trial pilot data and stakeholder feedback to evaluate our intervention targets, assessments and the primary outcome in the RCT were revised to target the effects of the EMPOWER intervention on peri (rather than post) traumatic stress.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EMPOWERBehavioural
EMPOWER is a manualized treatment delivered based in cognitive behavioral and acceptance and commitment therapies delivered by a trained mental health professional that utilizes breathing and grounding exercises, mindfulness meditation, psychoeducation, imaginal dialogue with the patient, and coping rehearsal techniques.
The total amount of time EMPOWER intervention is about 90 minutes, about 15 minutes each module. It can either be administered in one session or many sessions to accommodate the dynamic nature of ICU, and has two booster follow-up calls (roughly 45 minutes each) in the month following initial treatment.
Enhanced Usual CareOther
Enhanced usual care consists of standard ICU psychosocial support for caregivers like social work, chaplaincy, or palliative care team visits as charted in the patient's medical record. Participants assigned to EUC will also receive a general information guide for caregivers as well as a site-specific list of caregiver resources.
| Study group | Role | What they receive |
|---|---|---|
| Randomized controlled trial EMPOWER arm | Experimental | The EMPOWER arm includes six 15 minute modules delivered in a 1-on-1 format with the same interventionist, and 2 boosters (approximately 45 minutes each) conducted by phone.
Subjects who meet eligibility criteria will receive up to 4 sequential assessments before and after the EMPOWER intervention within 3 months conducted in person and by phone. Receives: Behavioral: EMPOWER |
| Randomized controlled trial Enhanced usual care arm | Placebo comparator | The usual care arm indicates regular ICU support for informal caregivers (i.e. social work, chaplaincy) as recorded in the patient's medical record, a general information packet for informal caregivers, and a site-specific resource list.
Subjects who meet eligibility criteria will receive up to 4 sequential assessments before and after the usual care within 3 months conducted in person and by phone. Receives: Other: Enhanced Usual Care |
| Open trial COVID-19 phase arm | Experimental | The COVID-19 open trial phase arm did not include randomization or control arm. All participants received the EMPOWER intervention. Assessments will occur pre-intervention, immediately post-intervention, and then 1-month and 3-months from post-intervention assessment. Receives: Behavioral: EMPOWER |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Peritraumatic Distress Inventory
Symptoms of peritraumatic distress, as measured by the Peritraumatic Distress Inventory (adapted to fit the ICU experience), will be compared between groups at post-intervention assessment (T2). The PDI consists of 13 likert-style items and total score can range from 0 to 52. Higher total scores represent greater symptom burden. Lower scores represent better outcomes.
Measured: At baseline (T1) and in the week following the intervention (T2)
Secondary outcomes (3)
Change in Anticipatory Grief
Anticipatory grief for patients who are not deceased, as measured by the Prolonged Grief-12, will be compared between groups at baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4)..The PG-12 consists of 12 items and total score can range from 0 to 57. Higher total scores represent greater symptom burden. Lower scores represent better outcomes.
Measured: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).
Change in Experiential Avoidance
Symptoms of experiential avoidance, as measured by the Brief Experiential Avoidance Questionnaire, will be compared between groups at baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4). The BEAQ consists of 15 items and total score can range from 15 to 90. Higher total scores represent greater symptom burden. Lower scores represent better outcomes.
Measured: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).
Change in Post-Traumatic Stress Disorder
Symptoms of post-traumatic stress disorder, as measured by the Impact of Events Scale-Revised, will be compared between groups at baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4). The IES-R consists of 22 items and total score can range from 0 to 88. Higher total scores represent greater symptom burden. Lower scores represent better outcomes.
Measured: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Intensive Care Units (ICU) are stressful places where life-and-death medical decisions are made and patients' surrogate decision-makers are exposed to potentially traumatic experiences. As the number of life-prolonging procedures administered to the patient rises, the patient's quality of life falls. Thus, interventions to improve the quality of life and care of ICU patients are needed.
EMPOWER is a cognitive-behavioral, acceptance-based intervention for patient surrogate decision-makers to reduce experiential avoidance of unpleasant thoughts and feelings related to thinking about patient death. By reducing surrogate's experiential avoidance, EMPOWER removes a barrier to advance care planning. EMPOWER aims to improve patient quality of life through enhancing value-directed end-of-life care while also empowering surrogates to cope with a loved one's potential impending death and adjust following the patient's ICU death or discharge. Specifically, investigators aim to:
- 1: Develop EMPOWER for surrogate decision-makers of critically ill patients who are at risk of becoming incapacitated or are currently unable to communicate in the ICU. Key informants, including bereaved ICU patient caregivers and clinicians, will be asked to evaluate the EMPOWER intervention manual to increase its potential tolerability, acceptability and efficacy.
- 2: Determine feasibility, tolerability, acceptability, and preliminary effects of EMPOWER on surrogate mental health.
- 3: Estimate the effects of EMPOWER on patient outcomes in the months following the ICU admission.
Hypothesis 1: Surrogate decision-makers who receive EMPOWER will have significantly lower levels of peritraumatic distress when compared to usual care condition at post intervention assessment (T2).
Hypothesis 2: Patients whose surrogates receive EMPOWER will have more value-concordant care, better quality of life, and better quality of death.
EMPOWER was first evaluated though a single site open trial (n=10). All 10 participants in the open trial phase received EMPOWER. Feedback from clinicians, bereaved stakeholders and results from the open trial were then used to refine the intervention and launch a multi-center randomized controlled trial to examine clinical superiority of EMPOWER to enhanced usual care. In order to adapt to restrictions in ICU visitation and meet the needs of family caregivers impacted by the COVID-19 pandemic, we then launched a second single arm open trial and paused recruitment for the RCT. All participants recruited during the open trial COVID-19 phase received EMPOWER. Beginning in August 2021, we resumed the RCT portion of the trial to meet the initial recruitment goals of the study (total n of RCT \& COVID-19 open trial=60).

Over 85% of these patients were unable to communicate, which resulted in the need for grieving, potentially traumatized caregivers to serve as the patient's surrogate decision-maker and make life-and-death decisions for a critically ill, uncommunicative patient. Additionally, caregivers of patients who die in the ICU are also at elevated risk of posttraumatic stress disorder (PTSD) in the months that follow the potentially traumatic ICU "exposures". These findings indicate a compelling need to address the varying mental health needs of informal caregivers and surrogate decision-makers of patients in the ICU from admission to after discharge, as well as to provide them with resources to clarify and inform the decision-making process regarding care for patients who are unable to communicate.
To address these needs, we have developed and will refine and evaluate EMPOWER, a mental health intervention for surrogate decision-makers of ICU patients who are at risk of becoming incapacitated or are currently unable to make medical decisions. Delivered by a trained mental health professional in the ICU setting, EMPOWER is a cognitive-behavioral, acceptance-based intervention designed to reduce "experiential avoidance" of unpleasant thoughts and feelings related to thinking about the patient's death and to provide active strategies for coping with peritraumatic distress and anticipatory grief. Additionally, by reducing surrogates' experiential avoidance, EMPOWER removes a barrier to advanced care planning and promotes the receipt of EoL care consistent with patient values. In this way, EMPOWER aims to facilitate EoL care that enhances patient quality of life while also empowering surrogates to cope with a loved one's potential impending death and adjust following the patient's ICU death or discharge.
This study is designed to obtain information on its feasibility, tolerability, acceptability, and preliminary effect size estimates to inform the planning of a larger, efficacy randomized controlled trial (RCT). In order to develop the RCT, the first 10 surrogate decision-makers were enrolled in an open trial to receive EMPOWER. In addition, during the manual refinement phase, up to 15 stakeholders (bereaved caregivers of ICU patients) were interviewed after reviewing the EMPOWER intervention manual. We then began a pilot RCT, randomizing surrogate decision-makers to receive either EMPOWER or enhanced usual care using a block-randomization strategy to determine condition assignment. In light of restrictions on recruitment and increased needs of surrogates during the COVID-19 pandemic, we paused the RCT portion of this trial and we recruited for a second open trial only administering EMPOWER. 60 surrogate-patient dyads were enrolled between the RCT and COVID-19 open trial. In August 2021, we resumed the RCT trial of the study. We resumed in person recruitment and randomization of participants to EMPOWER or EUC. Including the first open trial, we will enroll a total of 70 surrogate decision-makers of 70 current patients from the intensive care units at New York Presbyterian-Weill Cornell, New York Presbyterian-Queens, and Memorial Sloan Kettering Cancer Center. Research staff will regularly contact ICU physicians in person or by email and/or screen patient charts to identify eligible candidates based on the inclusion criteria.
Surrogates will be consented and screened. Those who score above 5 on either item measuring anxiety in the McGill Quality of Life Scale, or with a summed score of at least 8 on the first two items of the Partner Dependency Scale (PDS) will be randomized to receive EMPOWER or usual care in the RCT, or solely assigned to receive the intervention in the pilot trials. Surrogates will be assessed pre-intervention/baseline (Time point 1, T1), post-intervention (within a week of the surrogate's completion of the baseline assessment) (Time point 2, T2), 1-month post-T2 (Time point 3, T3), and 3-months post-T2(Time point 4, T4). Surrogates will be assigned to either control (usual care) or intervention group using block randomization in the RCT, and solely to EMPOWER in open trials.
EMPOWER is based on well-established cognitive-behavioral techniques that aim to promote the expression and understanding of a person's emotional reactions. The EMPOWER interventionist will be compassionate and attempt to teach subjects tools for remaining present-focused, validate participants' experience, explore participants' loved ones' and participants' own wishes, values and decision challenges, increase subjects acceptance and sense of permission to experience challenging emotions, and prepare participants for future distressing situations. Enhanced usual care will consist of a surrogate's interactions with social support services in the ICU as documented in the patient's medical chart, referrals for current site-specific resources for informal caregivers, and a packet providing general information and tips on serving as an informal caregiver.
HLM modeling will determine differences between surrogates and patients assigned to EMPOWER vs. enhanced usual care. The primary outcome is post-intervention (T2) differences on a measure of peritraumatic distress. Secondary outcomes are differences on measures of prolonged grief disorder, PTSD and experiential avoidance at one-month (T3) and three-month (T4) follow up from T2. Exploratory outcomes for surrogates are differences in reported symptoms of anxiety, depression, and decision regret at one-month (T3) and three-month (T4) follow up from T2. Exploratory outcomes for patients are differences in surrogate-reported quality of life, quality of death, and value concordant care. HLM models will include covariates, either as fixed-effect or time-varying, if those variables are found to be significantly statistically associated with both intervention assignment and the outcome examined.
Following a review of the open trial pilot data and stakeholder feedback to evaluate our intervention targets, assessments and the primary outcome in the RCT were revised to target the effects of the EMPOWER intervention on peri (rather than post) traumatic stress.

Interventions
| Intervention | Type | Arms |
|---|---|---|
| EMPOWEREMPOWER is a manualized treatment delivered based in cognitive behavioral and acceptance and commitment therapies delivered by a trained mental health professional that utilizes breathing and grounding exercises, mindfulness meditation, psychoeducation, imaginal dialogue with the patient, and coping rehearsal techniques. The total amount of time EMPOWER intervention is about 90 minutes, about 15 minutes each module. It can either be administered in one session or many sessions to accommodate the dynamic nature of ICU, and has two booster follow-up calls (roughly 45 minutes each) in the month following initial treatment. | Behavioural | Open trial COVID-19 phase arm, Randomized controlled trial EMPOWER arm |
| Enhanced Usual CareEnhanced usual care consists of standard ICU psychosocial support for caregivers like social work, chaplaincy, or palliative care team visits as charted in the patient's medical record. Participants assigned to EUC will also receive a general information guide for caregivers as well as a site-specific list of caregiver resources. | Other | Randomized controlled trial Enhanced usual care arm |
Primary outcome
Change in Peritraumatic Distress Inventory
Time frame: At baseline (T1) and in the week following the intervention (T2)
Symptoms of peritraumatic distress, as measured by the Peritraumatic Distress Inventory (adapted to fit the ICU experience), will be compared between groups at post-intervention assessment (T2). The PDI consists of 13 likert-style items and total score can range from 0 to 52. Higher total scores represent greater symptom burden. Lower scores represent better outcomes.
3 secondary outcomes
Change in Anticipatory Grief
Time frame: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).
Change in Experiential Avoidance
Time frame: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).
Change in Post-Traumatic Stress Disorder
Time frame: At baseline (T1) and in the week following the intervention (T2), one month and three months from baseline (T3 and T4).
