Caregiver subjective and physiological markers of stress and patient heart failure severity in family care dyads.

Greater family caregiver exposure to uncontrolled patient symptoms is predictive of greater caregiver psychological and physiological stress in dementia and other chronic illnesses, but these phenomena have not been well-studied in heart failure (HF) - a disease with high symptom burden. The purpose of this study was to test the hypothesis that worse patient functional status (as reflected by increasing HF symptoms) would be associated with elevated psychological and physiological stress for the caregiver. This was a secondary analysis of data from 125 HF caregivers in the Caregiver Opportunities for Optimizing Lifestyle (COOL) study. Psychological stress was measured on four dimensions: care-related strain/burden (Oberst Caregiving Burden Scale), depression (Center for Epidemiological Studies Depression Scale), anxiety (State-Trait Anxiety Index), and general stress (Perceived Stress Scale). Physiological stress was measured by markers of HPA axis function (elevated cortisol awakening response [CAR]), endothelial dysfunction (increased PAI-1), and inflammation (increased IL-6, hsCRP). HF patient functional status was quantified by caregiver assessment of New York Heart Association (NYHA) Class. Generalized linear models were used to test associations between patient NYHA Class and stress (one model per indicator). NYHA Class (ordinal) was backwards difference coded in each model to examine caregiver stress in relation to increasing levels of HF severity. Caregivers were mostly female and in their mid-fifties, with a slight majority of the sample being African American and the patient's spouse. Overall, patient functional status was associated with greater caregiver psychological and physiological stress. In terms of psychological stress, higher NYHA Class was significantly associated with greater caregiver anxiety and general stress, but not with caregiver burden or depression. In terms of physiological stress, higher NYHA Class was associated with elevated markers in all models (elevated CAR and higher IL-6, hsCRP, and PAI-1). Across models, most associations between NYHA Class and stress were present at relatively early stages of functional limitation (i.e. Class II), while others emerged when functional limitations became more severe. To inform timing and mechanisms for much-needed caregiver interventions, research is needed to determine which aspects of HF symptomatology are most stressful for caregivers across the HF trajectory.

A picture is worth a thousand words: exploring the roles of caregivers and the home environment of ventricular assist device patients.

AIMS: Caregivers of persons living with ventricular assist devices (VADs) are integrally involved in both medical and non-medical care. We sought to understand tasks caregivers perform after surgical recovery, ways the home is adapted for those tasks, and presence of home safety hazards. METHODS AND RESULTS: We conducted semi-structured interviews with persons living with a VAD and their caregivers. Pictures were taken of areas in the home where: (i) caregiving activities occurred, (ii) VAD or medical supplies were kept, and (iii) home adaptations were made for VAD care. Pictures were described in written detail and analysed. A qualitative descriptive approach was used for analysis. The sample consisted of 10 dyads, with mostly spousal relationships (60%) between male patients (60%) and female caregivers (80%). Three themes were identified: (i) Evolution of Caregiving and Support: Patients gain independence, but caregivers are still needed, (ii) Adapting the Home Environment: Changes are focused on functional needs, and (iii) Hidden Dangers: Illumination of safety concerns by photographs. Assistance with bathing, driveline care, and medication management were common caregiving tasks. Most home adaptations occurred in the bathroom and bedroom including sleeping recliners, shower chairs, removable shower heads, and hanging hooks to hold VAD equipment. Safety hazards included minimal space for safe ambulation, infection risk, and home-made adaptations to the environment. CONCLUSIONS: These findings describe key home caregiving tasks, home adaptations, and safety concerns that require further education and support. Utilizing pictures may be a feasible method for assessing VAD teaching, caregiving needs, and identifying potential risks.

"Talking Around It": A Qualitative Study Exploring Dyadic Congruence in Managing the Uncertainty of Living With a Ventricular Assist Device.

BACKGROUND: Vital components of communicating goals of care and preferences include eliciting the patient and caregiver's definition of quality of life, understanding meaningful activities and relationships, and exploring wishes for care at the end of life. Although current literature suggests framing conversations regarding end of life through the lens of meaning and quality of life, there is limited literature exploring dyadic congruence surrounding these important constructs among patients with ventricular assist devices (VADs) and their caregivers. OBJECTIVES: The purpose of this study was to explore congruence of VAD patient and caregiver perspectives regarding end of life, definitions of quality of life, and meaning in life while managing the uncertainty of living with a VAD. METHODS: We used thematic analysis to analyze semistructured qualitative interviews of 10 patient-caregiver dyads 3 to 12 months after VAD implantation. RESULTS: Three major themes were identified: (1) differing trajectories of uncertainty and worry, (2) a spectrum of end-of-life perspectives, and (3) enjoying everyday moments and independence. Overall, patients and caregivers had differing perspectives regarding uncertainty and end of life. Within-dyad congruence was most evident as dyads discussed definitions of meaning or quality of life. CONCLUSIONS: Dyadic perspectives on end of life, meaning in life, and quality of life can inform how palliative care and VAD teams approach conversations about planning for the end of life. Findings from this study can inform future shared decision-making interventions for patients living with VADs and their caregivers.

What matters when doctors die: A qualitative study of family perspectives.

BACKGROUND: The challenges of supporting the end-of-life preferences of patients and their families have often been attributed to poor understanding of the patient's condition. Understanding how physicians, as patients, communicate their end-of-life care preferences to their families may inform shared decision making at end of life. OBJECTIVES: The purpose of this study was to understand what matters to families of physicians when decision making with and for a physician who is approaching the end of life. DESIGN: Cross-sectional qualitative design. PARTICIPANTS: We conducted interviews with family members of deceased physicians. APPROACH: We analyzed the data using the constant comparison method to identify themes. KEY RESULTS: Family members (N = 26) rarely were unclear about the treatment preferences of physicians who died. Three overarching themes emerged about what matters most to physicians' families: (1) honoring preferences for the context of end-of-life care; (2) supporting the patient's control and dignity in care; and, (3) developing a shared understanding of preferences. Families struggled to make decisions and provide the care needed by the physicians at the end of life, often encountering significant challenges from the healthcare system. CONCLUSIONS: Even when disease and prognosis are well understood as in this group of physicians, families still experienced difficulties in end-of-life decision making. These findings highlight the need to specifically address preferences for caregiver, care setting and symptom management in shared end-of-life decision making conversations with patients and families.

Actor feedback and rigorous monitoring: Essential quality assurance tools for testing behavioral interventions with simulation.

INTRODUCTION: Simulation is a powerful tool for training and evaluating clinicians. However, few studies have examined the consistency of actor performances during simulation based medical education (SBME). The Simulated Communication with ICU Proxies trial (ClinicalTrials.gov NCT02721810) used simulation to evaluate the effect of a behavioral intervention on physician communication. The purpose of this secondary analysis of data generated by the quality assurance team during the trial was to assess how quality assurance monitoring procedures impacted rates of actor errors during simulations. METHODS: The trial used rigorous quality assurance to train actors, evaluate performances, and ensure the intervention was delivered within a standardized environment. The quality assurance team evaluated video recordings and documented errors. Actors received both timely, formative feedback and participated in group feedback sessions. RESULTS: Error rates varied significantly across three actors (H(2) = 8.22, p = 0.02). In adjusted analyses, there was a decrease in the incidence of actor error over time, and errors decreased sharply after the first group feedback session (Incidence Rate Ratio = 0.25, 95% confidence interval 0.14-0.42). CONCLUSIONS: Rigorous quality assurance procedures may help ensure consistent actor performances during SBME.
