Psychological Attachment Orientations of Surrogate Decision-Makers and Goals-of-Care Decisions for Brain Injury Patients in ICUs.

ABSTRACT: To determine whether ICU surrogates with "insecure" psychologic attachment orientations are more prone to requesting tracheostomy and gastrostomy (i.e., life-sustaining therapy) for severe acute brain injury patients with poor prognosis compared to surrogates with "secure" orientations.

Design

Cross-sectional survey from November 2017 to August 2018.

Setting

Single neuroscience ICU at an academic medical center.

Subjects

Consecutive sample of surrogates of patients admitted to the ICU with a minimum length of stay of 24 hours.

Interventions

None.

Measurements and main results

We identified surrogates' psychologic attachment orientation via a standard tool, the Relationship Questionnaire, and collected other surrogate and patient demographics. We also presented surrogates with a hypothetical scenario of an intubated severe acute brain injury patient with poor prognosis and asked each surrogate whether he or she would request life-sustaining therapy or comfort measures only. Fisher exact test was used to compare frequency of life-sustaining therapy selection between secure and insecure surrogates. Additionally, we conducted univariate and multivariate analyses to determine other independent predictors of life-sustaining therapy selection. Two-hundred seventy-five of 713 (38.6%) eligible respondents participated; 153 (55.6%) surrogates were secure, and 122 (44.4%) insecure. There was no significant difference in the proportion of secure respondents selecting life-sustaining therapy compared to insecure (18.3% vs 20.5%; p = 0.38). Although still nonsignificant, the observed difference was slightly greater for those with a specific "anxious" insecure subtype versus "nonanxious" (18.2% vs 23.0%; p = 0.41). Overall, a higher proportion of respondents selecting life-sustaining therapy (vs comfort measures only) reported feeling uncertain or very uncertain about the hypothetical decision (45.3% vs 9.5%; p < 0.001). In a multivariate model, nonwhite race and high religiosity were significant predictors of life-sustaining therapy selection.

Conclusions

Although surrogate attachment orientation is not predictive of life-sustaining therapy selection, nonwhite race and high religiosity are. Future interventions designed to support severe acute brain injury surrogates could focus on surrogates prone to selecting life-sustaining therapy with high degrees of uncertainty.

Project description:IntroductionAlthough shortcomings in clinician-family communication and decision making for incapacitated, critically ill patients are common, there are few rigorously tested interventions to improve outcomes. In this manuscript, we present our methodology for the Pairing Re-engineered Intensive Care Unit Teams with Nurse-Driven Emotional support and Relationship Building (PARTNER 2) trial, and discuss design challenges and their resolution.Methods and analysisThis is a pragmatic, stepped-wedge, cluster randomised controlled trial comparing the PARTNER 2 intervention to usual care among 690 incapacitated, critically ill patients and their surrogates in five ICUs in Pennsylvania. Eligible subjects will include critically ill patients at high risk of death and/or severe long-term functional impairment, their main surrogate decision-maker and their clinicians. The PARTNER intervention is delivered by the interprofessional ICU team and overseen by 4-6 nurses from each ICU. It involves: (1) advanced communication skills training for nurses to deliver support to surrogates throughout the ICU stay; (2) deploying a structured family support pathway; (3) enacting strategies to foster collaboration between ICU and palliative care services and (4) providing intensive implementation support to each ICU to incorporate the family support pathway into clinicians' workflow. The primary outcome is surrogates' ratings of the quality of communication during the ICU stay as assessed by telephone at 6-month follow-up. Prespecified secondary outcomes include surrogates' scores on the Hospital Anxiety and Depression Scale, the Impact of Event Scale, the modified Patient Perception of Patient Centredness scale, the Decision Regret Scale, nurses' scores on the Maslach Burnout Inventory, and length of stay during and costs of the index hospitalisation.We also discuss key methodological challenges, including determining the optimal level of randomisation, using existing staff to deploy the intervention and maximising long-term follow-up of participants.Ethics and disseminationWe obtained ethics approval through the University of Pittsburgh, Human Research Protection Office. The findings will be published in peer-reviewed journals.Trial registration numberNCT02445937.

Project description:IntroductionShared decision making is endorsed by guidelines for both acute kidney injury and critical care medicine. However, there is still a huge need for effective interventions, especially those focusing on decisions about renal replacement therapy for intensive care unit (ICU) patients with acute kidney injury. The decision aids provide evidence-based support for shared decision making, to achieve better decisions through enhanced knowledge of treatment options and treatment aligns with patients' preferences and values. Therefore, our objectives are to develop and evaluate a decision aid systematically and rigorously for family surrogate decision makers of ICU patients with acute kidney injury who need renal replacement therapy.Methods and analysisWe will use a systematic development process that focuses on user-centred design to develop and evaluate the decision aid in three phases: (1) development of a draft prototype for the decision aid based on extensive literature reviews, interviews with key stakeholders and evidence synthesis; (2) alpha testing ('near live' usability) the decision aid during simulated clinical encounters to test its comprehensibility, acceptability and usability and (3) beta testing ('live' usability) to examine the aid's clinical feasibility. User testing will be conducted using mixed-methods approach to support iterative revision of the decision aid. The IPDASi (V.4.0) will be used for following qualitative assessment. All interviews will be analysed by Colaizzi's seven-step approach to qualitative analysis. The coding scheme will use to analyse user interactions. Questionnaire surveys will be analysed using paired sample t-tests when related to the before-and-after survey, otherwise using one-sample t-test.Ethics and disseminationEthical approval for this research was obtained from the Ethics Committee of the First Affiliated Hospital of Army Medical University, PLA (Ref: KY2020104). All participants will sign a formal informed consent form. The findings will be published in peer-reviewed journals and reported in appropriate meetings.Trial registration numberChiCTR2000031613.

Project description:ObjectivesOptimistic expectations about prognosis by surrogate decision-makers in ICUs are common, but there are few data about the causes and clinical consequences. Our objective was to determine the causes of optimistic expectations about prognosis among surrogates and whether it is associated with more use of life support at the end of life.DesignProspective, multicenter cohort study from 2009 to 2012.SettingTwelve ICUs from multiple regions of the United States.SubjectsThe surrogates and physicians of 275 incapacitated ICU patients at high risk of death.InterventionsNone.Measurements and main resultsSurrogates and physicians completed a validated instrument assessing their prognostic expectations for hospital survival. We determined the proportion of surrogates with optimistic expectations, defined as a prognostic estimate that was at least 20% more optimistic than the physician's, then determined how frequently this arose from surrogates miscomprehending the physicians' prognosis versus holding more hopeful beliefs compared with the physician. We used multivariable regression to examine whether optimistic expectations were associated with length of stay, stratified by survival status, and time to withdrawal of life support among nonsurvivors. Overall, 45% of surrogates (95% CI, 38-51%) held optimistic expectations about prognosis, which arose from a combination of misunderstanding the physician's prognostic expectations and from holding more hopeful beliefs compared with the physician. Optimistic expectations by surrogates were associated with significantly longer duration of ICU treatment among nonsurvivors before death (β coefficient = 0.44; 95% CI, 0.05-0.83; p = 0.027), corresponding to a 56% longer ICU stay. This difference was associated with a significantly longer time to withdrawal of life support among dying patients whose surrogates had optimistic prognostic expectations compared with those who did not (β coefficient = 0.61; 95% CI, 0.16-1.07; p = 0.009).ConclusionsThe prevalent optimism about prognosis among surrogates in ICUs arises both from surrogates' miscomprehension of physicians' prognostications and from surrogates holding more hopeful beliefs. This optimism is associated with longer duration of life support at the end of life.
