Patient, Caregiver, and Clinician Perceptions of Ventricular Assist Device Self-care Education Inform the Development of a Simulation-based Mastery Learning Curriculum

[Healthcare quality and safety in left ventricular assist device therapy from the patient perspective: A qualitative study on relevant aspects of care]

INTRODUCTION

Implantation of a left ventricular assist device (LVAD) requires extensive aftercare. It is largely unclear how aftercare should be designed from the patients' perspective. Implications can be developed based on an examination of the healthcare context. Its main components are mapped on five tiers in the Human Factors of Home Health Care Model by Henriksen, Joseph, and Zayas-Caban (2009). Using this model, the present study explores the patient perspective on the context of healthcare after an LVAD implantation.

METHODS

We employed a qualitative cross-sectional study, in which LVAD patients participated in semi-structured interviews. The transcribed interviews were analyzed using content analysis. First, relevant meaning units were identified and deductively categorized into the model. Then, categories of care-related aspects were developed inductively within each of the model tiers.

RESULTS

We interviewed 18 patients aged 33 to 78 years who had been living with the LVAD between a few weeks and more than 10 years. Twenty-eight categories related to care aspects were developed within the model tiers: 3 categories on patient characteristics (e.g., self-management skills), 3 on caregiver characteristics (e.g., professionalism), 11 healthcare-related tasks and requirements (e.g., wound management), 8 on factors of the physical environment (e.g., controllability), medical devices and technologies (e.g., carrying systems for external components), and cultural, social and community environment (e.g., interaction with peers), as well as 3 on external environmental factors (e.g., healthcare infrastructure).

DISCUSSION

The present study represents the first investigation focusing on aspects of the healthcare context influencing healthcare quality and safety from the perspective of LVAD patients in Germany. LVAD aftercare covers a broad and complex range of tasks. For this, patients, caregivers and healthcare professionals need specific knowledge, which is lacking in various respects. In the first place, this is compensated by the patients' own initiative and the personal care provided by the VAD outpatient clinics.

CONCLUSION

Three key recommendations to optimize aftercare from the patient perspective are derived: Patients would benefit from a more flexible and decentralized aftercare concept, to which telemedicine could contribute. LVAD-specific expertise among general healthcare providers is perceived as insufficient by patients and could be strengthened through training and counseling services. The broad scope of tasks and the high level of responsibilities in LVAD aftercare pose challenges for patients and their families, which could be addressed through continuous information and training programs.

Communicating Diagnostic Uncertainty at Emergency Department Discharge: A Simulation-Based Mastery Learning Randomized Trial

PURPOSE

There are no standardized approaches for communicating with patients discharged from the emergency department with diagnostic uncertainty. This trial tested efficacy of the Uncertainty Communication Education Module, a simulation-based mastery learning curriculum designed to establish competency in communicating diagnostic uncertainty.

METHOD

Resident physicians at 2 sites participated in a 2-arm waitlist randomized controlled trial from September 2019 to June 2020. After baseline (T1) assessment of all participants via a standardized patient encounter using the Uncertainty Communication Checklist (UCC), immediate access physicians received training in the Uncertainty Communication Education Module, which included immediate feedback, online educational modules, a smartphone-based application, and telehealth deliberate practice with standardized patients. All physicians were retested 16-19 weeks later (T2) via in-person standardized patient encounters; delayed access physicians then received the intervention. A final test of all physicians occurred 11-15 weeks after T2 (T3). The primary outcome measured the percentage of physicians in the immediate versus delayed access groups meeting or exceeding the UCC minimum passing standard at T2.

RESULTS

Overall, 109 physicians were randomized, with mean age 29 years (range 25-46). The majority were male (n = 69, 63%), non-Hispanic/Latino (n = 99, 91%), and White (n = 78, 72%). At T2, when only immediate access participants had received the curriculum, immediate access physicians demonstrated increased mastery (n = 29, 52.7%) compared with delayed access physicians (n = 2, 3.7%, P < .001; estimated adjusted odds ratio of mastery for the immediate access participants, 31.1 [95% CI, 6.8-143.1]). There were no significant differences when adjusting for training site or stage of training.

CONCLUSIONS

The Uncertainty Communication Education Module significantly increased mastery in communicating diagnostic uncertainty at the first postintervention test among emergency physicians in standardized patient encounters. Further work should assess the impact of clinical implementation of these communication skills.

Ventricular Assist Device Self-care Education at Tertiary Care Medical Centers

Ventricular assist device (VAD) implantation requires patients and caregivers to attain self-care knowledge and skills before discharge from implant hospitalization. Inability to perform these skills can have devastating outcomes (i.e., death from pump malfunction, driveline site infections, and stroke). No standard-of-care guiding VAD self-care education exists. We sought to describe how select tertiary care VAD implant centers across the United States currently educate VAD patients and their caregivers. Using a multiple case studies design with a purposive sampling strategy, we conducted semistructured interviews of VAD coordinators responsible for VAD education at 18 centers. From audio recording of interviews, we used rapid qualitative analysis to organize and analyze the data. All centers spent significant time and effort educating patients and caregivers on VAD self-care. Although centers teach similar content, the rigor of assessments and follow-up education differed vastly. Only 3/18 (17%) centers performed competency-based assessments with a skills checklist and minimum passing standard assessing readiness to perform VAD self-care independently. Twelve of 18 (67%) centers provided formal follow-up education to address skills decay, yet wide variation existed in timing and content of education. Due to the diversity among centers regarding VAD self-care education, more prescriptive practice guidelines are needed.

Effect of Ventricular Assist Device Self-care Simulation-Based Mastery Learning on Driveline Exit Site Infections: A Pilot Study

BACKGROUND

Ventricular assist device simulation-based mastery learning (SBML) results in better patient and caregiver self-care skills compared with usual training.

OBJECTIVE

The aim of this study was to evaluate the effect of SBML on driveline exit site infections.

METHODS

We compared the probability of remaining infection free at 3 and 12 months between patients randomized to SBML or usual training.

RESULTS

The SBML-training group had no infections at 3 months and 2 infections at 12 months, yielding a Kaplan-Meier estimate of the probability of remaining infection free of 0.857 (95% confidence interval [CI], 0.692-1.00) at 12 months. The usual-training group had 6 infections at 3 months with no additional infections by 12 months. Kaplan-Meier estimates of remaining infection free at 3 and 12 months were 0.878 (95% CI, 0.758-1.00) and 0.748 (95% CI, 0.591-0.946), respectively. Time-to-infection distributions for SBML versus usual training showed a difference in 12-month infection rates of 0.109 (P = .07).

CONCLUSIONS

Ventricular assist device self-care SBML resulted in fewer 12-month infections.

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.
