Nighttime sleep and daytime sleepiness patterns among left ventricular assist device patients.

Despite the high prevalence of sleep disturbance in the heart failure population, information about its consequence on daytime function in patients with left-ventricular assist devices (LVADs) is limited. This study examined the nighttime and daytime sleep patterns and changes from pre-implant to 6 months post-implant. This study included 32 LVAD patients. Demographics, nighttime and daytime sleep variables were collected pre-implant and at 1, 3, and 6 months post-implant. Wrist actigraphy and self-report questionnaires measured objective and subjective sleep, respectively. Objective nighttime sleep data were sleep efficiency (SE), sleep latency (SL), total sleep time (TST), wake after sleep onset (WASO), and sleep fragmentation (SF). Objective daytime sleep data were nap times. Self-reported Subjective Sleep Quality Scale (SSQS) and Stanford Sleepiness Scale (SSS) were subjective measures. Increased SF and WASO scores and decreased TST and SE scores were found pre-LVAD implant, indicative of poor sleep quality. TST, SE, naptime and SSQS scores were higher at 3 and 6 months post-implant compared to baseline. Decreases in TST and SF scores were observed at 3 and 6 months post-implant along with increases in SSS scores. Increasing SSS scores and decreasing overall scores from pre- and up to 6 months post-implant suggest improvement in daytime function. This study provides information on sleep-daytime function in the LVAD patient population. Improvements in daytime sleepiness do not imply "good" sleep quality, consistent with the extant knowledge in LVAD literature. Future investigations should elucidate the mechanism by which sleep-daytime function influences quality of life.

A pilot clinical trial of a self-management intervention in patients with a left ventricular assist device.

Self-management is a health behavior known to predict treatment outcomes in patients with multiple co-morbidities and/or chronic conditions. However, the self-management process and outcomes in the left-ventricular assist device (LVAD) population are understudied. This pilot randomized control trial (RCT) evaluated the feasibility of a novel "smartphone app-directed and nurse-supported self-management intervention" in patients implanted with durable LVADs. Assessments included behavioral (self-efficacy and adherence), clinical (complications), and healthcare utilization (unplanned clinic, emergency room (ER) visits, and re-hospitalization) outcomes, completed at baseline (pre-hospital discharge) and months 1, 3, and 6 post-hospital discharge. Intervention patients (n = 14) had favorable patterns/trends of results across study outcomes than control patients (n = 16). Notably, intervention patients had much lower complications and healthcare utilization rates than controls. For example, intervention patients had 2 (14.3%) driveline infections in 6 months while control patients had 3 (19.0%). Additionally, at month 3, intervention patients had 0% ER visits versus 36% of control patients. At month 6, the mean cumulative number of re-hospitalizations for the control group was higher (0.9 ± 0.93) than intervention (0.3 ± 0.61) group. Despite the small sample size and limitations of feasibility/pilot studies, our outcomes data appeared to favor the novel intervention. Lessons learned from this study suggest the intervention should be implemented for 6 months post-hospital discharge. Further research is needed including large and rigorous multi-center RCTs to generate knowledge explaining the mechanism of the effect of self-management on LVAD treatment outcomes.

Sleep and self-care correlates before and after implantation of a left-ventricular assist device (LVAD).

The impact of sleep on LVAD patients' self-care behaviors is unknown. This study examined the patterns and changes of patients sleep quality (SQ), daytime sleepiness (DS), instrumental activities of daily living (IADL), and self-care capability (SCC) before and after LVAD. In addition, the relationships among these variables were explored. This observational study consisted of 38 subjects from two VAD Centers in Michigan. The subjects completed self-reported demographics and psychometrically sound SQ, DS, IADL, and SCC questionnaires before LVAD implant and at 1, 3, and 6 months after implant. Data were analyzed using descriptive statistics, linear mixed models, and partial least square models. Subjects (mean age, 56.3 ± 10.3 years) were predominantly white (63%), male (68%), married (60%), and living with caregivers (92%). Over 70% had axial flow LVADs implanted as bridge-to-transplant (55%). Subjects' SQ was poor throughout the study period, along with high normal-to-excessive levels of DS. Problems with IADL before implant were significantly reduced at 1 through 6 months after implant. SCC ranged from "good" to "excellent" before and after implant. Significant relationships between SQ and IADL (ß = 0.43, p < 0.01) and DS and SCC (ß = - 0.62, p < 0.01) were found. In conclusion, poor SQ and high degrees of DS were prevalent before and up to 6 months after LVAD implant. The data inferred that the improvement in IADL was associated with an improvement in SQ. Research is needed to clarify the negative impact of DS on SCC and explain the contributions of caregivers on patients' SCC over time.

Night-time care routine interaction and sleep disruption in adult cardiac surgery.

AIMS AND OBJECTIVES: To explore the context and the influence of night-time care routine interactions (NCRIs) on night-time sleep effectiveness (NSE) and daytime sleepiness (DSS) of patients in the cardiac surgery critical-care and progressive-care units of a hospital. BACKGROUND: There exists a paucity of empirical data regarding the influence of NCRIs on sleep and associated outcomes in hospitalised adult cardiac surgery patients. METHODS: An exploratory repeated-measures research design was employed on the data provided by 38 elective cardiac surgery patients (mean age 60.0 ± 15.9 years). NCRI forms were completed by the bedside nurses and patients completed a 9-item Visual Analogue Sleep Scale (100-mm horizontal lines measuring NSE and DSS variables). All data were collected during postoperative nights/days (PON/POD) 1 through 5 and analysed with IBM SPSS software. RESULTS: Patient assessment, medication administration and laboratory/diagnostic procedures were the top three NCRIs reported between midnight and 6:00 a.m. During PON/POD 1 through 5, the respective mean NSE and DSS scores ranged from 52.9 ± 17.2 to 57.8 ± 13.5 and from 27.0 ± 22.6 to 45.6 ± 16.5. Repeated-measures ANOVA showed significant changes in DSS scores (p < .05). NSE and DSS were negatively correlated (r = -.44, p < .05), but changes in NSE scores were not significant (p > .05). Finally, of 8 NCRIs, only 1 (postoperative exercises) was significantly related to sleep variables (r > .40, p < .05). CONCLUSION AND RELEVANCE TO CLINICAL PRACTICE: Frequent NCRIs are a common occurrence in cardiac surgery units of a hospital. Further research is needed to make a definitive conclusion about the impact of NCRIs on sleep/sleep disruptions and daytime sleepiness in adult cardiac surgery. Worldwide, acute and critical-care nurses are well positioned to lead initiatives aimed at improving sleep and clinical outcomes in cardiac surgery.

An exploratory study of the patients' sleep patterns and inflammatory response following cardiopulmonary bypass (CPB).

AIMS AND OBJECTIVES: To describe sleep patterns and inflammatory response postCPB, determine sleep pattern changes and inflammatory response over time and explore relationships between sleep and biomarkers of stress and inflammation. BACKGROUND: Despite the numerous citations of the role of sleep in restoration and health maintenance, a paucity of research exists about this phenomenon in patients undergoing CPB. Specifically, there is no research that has explored correlations between sleep patterns and systemic inflammatory response in adult cardiac surgery patients. DESIGN: Exploratory, repeated-measures, correlational study. METHOD: Subjects were recruited from a Midwestern urban hospital. Of the 25 eligible subjects, 16 males and four females completed the study. Wrist actigraphy was used to measure sleep variables. Salivary cortisol and C-reactive protein (C-RP) levels were measured daily. Data were collected during postoperative nights/days 1 through 4 (T1-T4). RESULTS: Subjects' sleep onset latency (SOL) median scores (0 minute) were within normal range across time periods, whereas median scores for wake after sleep onset (WASO > 270 minutes), sleep fragmentation index (SFI >51%), total sleep time (<153 minutes) and sleep efficiency index (SEI <36%) fell outside the normal ranges. Changes in the median sleep scores over time, however, were not significant at p > 0·05. Median cortisol levels were within normal range (0·3-0·8 µg/dl) from T1-T4, but the C-RP level peaked at T2 (median = 2370 pg/ml). Strong correlations were found: (1) between SFI-cortisol (rs = 0·82), C-RP (rs = 0·65) - WBC (rs = 0·69); (2) between SEI-C-RP (rs = 0·58); (3) between WASO-WBC (rs = 0·48), WASO and cross-clamp time (rs = 0·50); and (4) between SOL-age (rs = -0·55) at p < 0·05. CONCLUSIONS: Subjects were severely sleep-deprived with inflammatory response exaggerations warranting further investigations using larger sample sizes. RELEVANCE TO CLINICAL PRACTICE: This study offers a foundation for developing a conceptual model explaining mechanisms of sleep disturbance and inflammatory response postCPB. This knowledge is crucial for testing sleep-promoting interventions to modulate inflammatory responses essential for preventing complications, and restoring health.

Initial evaluation of the Robert Wood Johnson Foundation Nurse Faculty Scholars program.

BACKGROUND: The Robert Wood Johnson Foundation Nurse Faculty Scholars (RWJF NFS) program was developed to enhance the career trajectory of young nursing faculty and to train the next generation of nurse scholars. Although there are publications that describe the RWJF NFS, no evaluative reports have been published. The purpose of this study was to evaluate the first three cohorts (n = 42 scholars) of the RWJF NFS program. METHODS: A descriptive research design was used. Data were derived from quarterly and annual reports, and a questionnaire (seven open-ended questions) was administered via Survey Monkey Inc. (Palo Alto, CA, USA). RESULTS: During their tenure, scholars had on average six to seven articles published, were teaching/mentoring at the graduate level (93%), and holding leadership positions at their academic institutions (100%). Eleven scholars (26%) achieved fellowship in the American Academy of Nursing, one of the highest nursing honors. The average ratings on a Likert scale of 1 (not at all supportive) to 10 (extremely supportive) of whether or not RWJF had helped scholars achieve their goals in teaching, service, research, and leadership were 7.7, 8.0, 9.4, and 9.5, respectively. The majority of scholars reported a positive, supportive relationship with their primary nursing and research mentors; although, several scholars noted challenges in connecting for meetings or telephone calls with their national nursing mentors. CONCLUSIONS: These initial results of the RWJF NFS program highlight the success of the program in meeting its overall goal-preparing the next generation of nursing academic scholars for leadership in the profession.

A preliminary investigation of symptom pattern and prevalence before and up to 6 months after implantation of a left ventricular assist device.

Despite increased use of left ventricular assist devices (LVAD) in patients with advanced or end-stage heart failure; little is known about the reoccurrence of common heart failure symptoms (e.g., fatigue) after LVAD implantation. The objective of this study was to investigate the prevalence and pattern of selected heart failure symptoms and identify changes in symptom patterns before and up to 6 months after LVAD implantation. We used self-report questionnaires to collect data from patients (n = 12) and measure symptoms at baseline, 1 and 2 weeks, and 1, 3, and 6 months after LVAD. We found that high levels of fatigue, anxiety, depression, and sleep disturbance were prevalent during these periods. However, we did not find any significant changes in symptom pattern over time. The preliminary findings set the starting point for large-scale studies fundamental to advances in symptom-management research in LVAD and for other patients living with artificial organs.

Practice pattern and professional issues of nurse practitioners in mechanical circulatory support programs in the United States: a survey report.

CONTEXT: Few data-based reports about the role and work environment of advanced practice nurses, specifically nurse practitioners in mechanical circulatory support programs, have been published. OBJECTIVE: To describe the practice pattern and professional issues confronted by nurse practitioners in the rapidly evolving and expanding mechanical circulatory support programs in the United States. DESIGN: A descriptive research design was employed using the data from the 2010 mechanical circulatory support nurses survey. Quantitative and qualitative data that pertained to the demographic and practice profiles as well as barriers and overall issues faced by the nurse practitioners in their clinical practice were analyzed. PARTICIPANTS: Nonrandom sample of 48 nurse practitioners from 95 mechanical circulatory support programs nationwide. RESULTS: The practice pattern of nurse practitioners in mechanical circulatory support programs is similar to the practice pattern reported for nurse practitioners in acute and critical care settings. However, only 44% and 10% of nurse practitioners in mechanical circulatory support programs are authorized to admit and transfer patients into and out of the hospital, respectively. High workload, lack of institutional support, knowledge deficit, role ambiguity, lack of professional recognition, and burnout were the common issues faced by the participants in their clinical practice. CONCLUSION: The results provide preliminary evidence on the practice pattern, restrictions, and work environment issues that may threaten the viability of an mechanical circulatory support program in which nurse practitioners play a crucial role. Implications for clinical practice, research, and policy development are discussed.

Proposed Mechanism of Adherence in Caregivers Providing Care to Adults Living with a Left Ventricular Assist Device.

Introduction: The left ventricular assist device (VAD) is commonly used as the bridge-to-transplantation therapy for heart failure patients who are on waitlist of heart transplant. The caregivers' adherence to the homecare regimen plays a vital role in patient outcomes. There is little evidence about the factors related to the caregiver adherence. The purpose of this study was to determine the factors influencing adherence in caring for patients living with a left ventricular device. Methods: The data were collected from 4 online caregiver support groups. Multiple linear regression models were used to determine associations between key variables. The structure equation modeling was used to identify the mediators of caregiver adherence. Results: A total of 96 participants' data entered the final analysis. The average age of the participants was 49.8 (SD = 12.88) years, majority were white (84%), female (80%), and married (81%). Caregiver self-efficacy was positively related to their adherence (r = 0.460, P < 0.001). Caregiver knowledge did not mediate the effect of training on self-efficacy. Caregiver self-efficacy did not mediate the effect of knowledge on adherence. There was no interaction between practice hours and knowledge on adherence. Discussion: The findings suggest significant association between caregiver self-efficacy and adherence to left ventricular assist home-care regimens. Additional research is needed to identify factors influencing caregiver adherence, leading to the development of evidence-based practice guidelines and to improve the outcomes in advanced heart failure patients living with left VAD.

From insiders' perspectives: adjusting to caregiving for patients with left ventricular assist devices.

CONTEXT: Caregivers for patients with a long-term implantable left ventricular assist device have a very important role in helping patients maintain their health and well-being and attain an improved quality of life. Although the caregiving tasks, burdens, and challenges of family caregivers have been described in the literature, we know little about how caregivers adjust to or accommodate the new role in their lives. OBJECTIVE: To explore and describe the lifestyle adjustments of caregivers for adults living with a left ventricular assist device as a bridge to heart transplant or destination therapy. DESIGN: A hermeneutic phenomenology was used as a guide for interviews and analysis of the data. PARTICIPANTS: A purposive convenience sample of 5 women, aged 39 to 71 years, who had served as caregivers of a left ventricular assist device patient for at least 3 months. SETTING: Recruitment and data collection (interviews) were conducted in an outpatient clinic for the mechanical circulatory support program of a large academic medical center in the Midwest. RESULTS: Three main themes (caregiving: a "24/7" responsibility, coping strategies, and satisfaction) and 13 subthemes emerged from the data. CONCLUSIONS: Lifestyle adjustments with caregiving may become easier over time, and with effective use of coping strategies, caregivers accept their new caregiving role as part of life.

Sleep and daytime sleepiness of patients with left ventricular assist devices: a longitudinal pilot study.

CONTEXT: No empirical longitudinal data on sleep and daytime sleepiness patterns in patients with an implantable left ventricular assist device (LVAD) exist. OBJECTIVE: (1) To describe the sleep patterns (sleep onset latency, sleep efficiency, sleep fragmentation index, total sleep time, and wake after sleep onset), sleep quality, and daytime sleepiness variables and (2) to determine the change in the pattern of these variables before and up to 6 months after LVAD implantation. DESIGN: A longitudinal descriptive repeated-measures design was used. Patients wore wrist actigraphs (AW64 Actiwatch), which objectively measured sleep, for 3 consecutive days and nights before LVAD implant and at the first and second week and first, third, and sixth month after implantation. During these periods, patients also completed questionnaires on sleep quality and daytime sleepiness. Patients-Twelve of 15 patients completed the 6-month data. Data were analyzed by using descriptive statistics and repeated-measures analysis of variance. RESULTS: We found long sleep onset latencies and low sleep efficiency across time periods. High sleep fragmentation index was noted at baseline and 1 week after LVAD. Short total sleep times, long wake-after-sleep-onset durations, and poor sleep quality were evident at baseline and persisted up to 6 months after LVAD implantation. Low alertness level, a manifestation of sleepiness, was common during late morning to early evening hours. However, only sleep efficiency and wake after sleep onset showed significant changes in pattern (P < .05). CONCLUSION: Sleep disturbance and daytime sleepiness may be prevalent before and up to 6 months after LVAD implantation, warranting further investigation.

Patient-Reported Issues Following Left Ventricular Assist Device Implantation Hospitalization.

The purpose of this study was to explore the information reported by patients via a smartphone application (VAD Care App) used for left ventricular assist device (LVAD) self-care monitoring and reporting post hospital discharge. Specific aims were to examine the type and frequency of issues reported by patients through the app during months 1, 3, and 6 postdischarge. An exploratory-descriptive research design was used with 17 patients (12 males and 5 females) with durable LVADs, mean age of 48.6 ± 16 years. Data generated by the patients' daily smartphone app usage more than 6 months were extracted from the server. Data were coded and clustered according to issues reported by patients via the app and analyzed with descriptive statistics. Three clusters of issues were found: physiologic, behavioral (self-care), and signs and symptoms. LVAD flows and pulsatility indices, hypertension, driveline care, and heart failure symptoms were worse at month 1, and then appeared to improve at months 3-6. However, abnormal levels of the international normalization ratio were common at all assessment points. Further research is needed to understand the mechanism of the reported issues on treatment outcomes, then develop and test interventions to inform evidence-based practice and clinical guidelines for smartphone apps used in LVAD self-care monitoring.

Burnout and Quality of Work Life Among Nurse Practitioners in Ventricular Assist Device Programs in the United States.

BACKGROUND: A mixed-method study of role stress and work intensity among nurse practitioners (NPs) in mechanical circulatory support (MCS) programs in the United States reported a qualitative data related to burnout. We empirically investigated this phenomenon by pursuing the following specific aims: (1) describe levels of personal burnout (PB), work-related (WB) burnout, and client-related burnout (CB) and quality of work life (QOWL) among MCS-NPs; (2) determine the relationship between burnout and QOWL variables; and (3) identify which type of burnout is a predictor of QOWL. METHODS: We employed an exploratory correlational research design. Demographics, work characteristics, and psychometrically robust measures of burnout and QOWL were completed by 47 MCS-NPs from various regions of the United States. Data were analyzed with descriptive and inferential statistics. RESULTS: Higher levels of burnout (PB, WB, and CB) were associated with lower levels of QOWL (r = -.52 to -.64, P < .001). Of the 3 types of burnout, WB burnout showed a significant predictor of QOWL (R2 = .44, P < .01). Multiple regression models showed that a 1 point increase in mean score of WB would decrease a mean QOWL score by 0.64 after controlling the effect of PB and CB. Some dimensions of QOWL were associated with work/hospital characteristics (r > -.30, P values <.05). CONCLUSION: Work-related burnout is negatively associated with low QOWL among NPs. Hospital/work environment was contributing factors to high burnout and low QOWL. Further research is needed to confirm the findings including the effect of burnout and QOWL on patient and ventricular assist device program outcomes.

Nurses' Competence Caring for Hospitalized Patients With Ventricular Assist Devices.

BACKGROUND: Nursing care is an essential component of the delivery of high-quality patient care for advanced heart failure patients with ventricular assist devices (VADs). However, there is little information about how VAD patient care competence is formed, and there are no empirical data regarding the bed nurses' competence. OBJECTIVES: The aim of this study was to explain how nurses perceived their competence related to VAD technology and how they utilized resources to equip themselves for the management of patients with implantable VADs. METHODS: An exploratory correlational research design was used in this study. Online surveys including demographic and work characteristics questionnaires as well as VAD Innovation in Nursing Appraisal Scale (knowledge, adoption, and communication) were completed by 237 critical-care unit and progressive care unit (PCU) nurses. RESULTS: Ventricular assist device knowledge, adoption, and communication of innovation mean scores were 3.9 ± 0.6, 3.9 ± 0.8, and 3.7 ± 0.9, respectively, indicating moderate/high levels. Critical-care unit nurses reported higher levels of knowledge (3.7 vs 3.6) and adoption (4.0 vs 3.8; P < .05) of innovation than did the PCU nurses, with no differences in communication. Compared with PCU nurses, critical-care unit nurses were more likely to seek VAD competence-related information using mass media. Innovation and adoption were associated with years of nursing experience and some hospital characteristics. CONCLUSION: Critical-care unit nurses have higher self-reported VAD care competence than PCU nurses. Further research is needed to confirm the findings and link nurse competence with VAD patient outcomes.

Development of an Instrument for Measuring Self-Care Behaviors After Left Ventricular Assist Device Implantation.

BACKGROUND: Successful long-term left ventricular assist device (LVAD) therapy necessitates a high degree of self-care. We aimed to develop an instrument that measures self-care behaviors in adult patients living with an LVAD. METHODS: We used the method to develop patient-reported outcomes recommended by the US Food and Drug Administration. Prior to developing the instrument, a literature review was conducted to generate items using the middle-range theory of self-care of chronic illness as a guiding framework. A 2-round Delphi method, involving 17 clinicians with expertise in heart failure and assist devices from the Netherlands, Israel, United States, Canada, and Japan, was used to generate and select items. In the first Delphi survey, the levels of importance, relevance, and clarity of items in the instrument were evaluated. The second Delphi survey was performed to gain consensus on the final selection of items. We also examined face validity. RESULTS: A preliminary 37-item version of the Self-Care Behavior Scale was produced. The first panel judged 33 items as important and relevant, taking out 4 items due to vague wording and duplication and adding in 4 items. In the final 33-item version, 19 items address self-care maintenance behaviors, 10 items address self-care monitoring behaviors, and 4 items address self-care management behaviors. Patients (N = 25) did not have any difficulties understanding items and report any missing items. CONCLUSION: The 33-item Self-Care Behavior Scale for patients with heart failure having an LVAD has been developed and is ready for further psychometric testing.

Ready, Set, Go: How Patients and Caregivers Are Prepared for Self-Management of an Implantable Ventricular Assist Device.

Since the first use of an implantable ventricular assist device (VAD) nearly 3 decades ago, many VAD Centers in the United States expect patients and caregivers to manage the device and related care following hospital discharge. Despite this customary practice and the rapid advancements in VAD technology, no research data about the patient and caregiver preparations exist for self-management of VAD. This study explored the process of preparing patients and caregivers for VAD care before hospital discharge along with their perceived experiences of the discharge process. Using an exploratory research design, we collected the data with self-administered demographics and VAD Hospital Discharge Survey questionnaires. We analyzed the data provided by 102 patients and 116 caregivers from different regions in the United States. Patients' mean age was 51.4 ± 13.8 years; they were predominantly White (78%); male (66%); and duration of device between 2 and 74 months. Caregivers were predominantly White (80%); female (81%); and had a mean of age 48.9 ± 12.7 years. Participants reported that their VAD care preparations, a crucial component of hospital discharge, were extensive and intensive processes comprising education, training, competency validation, and provision of resources for VAD self-management in home settings. Participants were satisfied with the process and felt prepared for discharge. Further research is needed to rectify the study limitations, advance the science of VAD self-management, and develop evidenced-based VAD self-management guidelines that are aimed at optimizing longevity of the VAD, patients' health, and quality of life.

The Relationship of Anxiety, Depression, and Quality of Life in Adults With Left Ventricular Assist Devices.

Psychological distress, including anxiety and depression, is commonly reported by patients with implantable left ventricular assist devices (LVADs). Still, the influence of anxiety and depression on global quality of life (QOL) is unknown. Moreover, the empirical data of LVAD patients' QOL is limited to 24 months. This study examined the differences in anxiety, depression, and QOL based on 3 LVAD implant duration groups (≤12, 13-24, and ≥25 months). We also examined the influence of anxiety and depression on QOL. An observational cross-sectional study design was employed using self-administered demographics, anxiety, depression, and global QOL questionnaires. A total of 100 patients (mean age 52 ± 13.3 years) across the United States completed the study. In the 3 implant duration groups, we found no significant differences in anxiety and depression, but the global QOL scores of patients with LVADs ≥ 13 months were significantly worse than those of patients with LVADs ≤ 12 months. Also, the correlations between QOL and either anxiety or depression were significant: Pearson's r ranged from -0.44 to -0.65 with all p values <0.0001. Compared with anxiety, depression is a stronger predictor of QOL. Our data showed that when depression is increased by 1 unit, the average QOL decreased by 0.76 units, assuming anxiety is held constant. This study uncovered relationships among anxiety, depression, and QOL in patients with long-term LVADs. Longitudinal research is needed to confirm our findings and explore factors that may contribute to worse QOL, particularly, those patients supported with LVADs beyond 13 months.

Ventricular Assist Device Self-Management Issues: The Patient and Caregiver Perspectives.

Despite technological advancements, ventricular assist device (VAD) self-management (SM) remains complex. Using a descriptive mixed-method research, we examined the VAD care issues reported by nondyadic sample of 102 patients and 116 caregivers in the United States. Participants (mean age, 50.0 ± 13.1 years) were predominantly white (80%), female (59%), and married (77%). Quantitative and qualitative data revealed the patients/caregivers' need for competency assessment and reassessment of VAD care after discharge. Competent home-care registered nurses (RNs) and on-going communications with VAD care team are needed in support for VAD SM.

Development and Feasibility of Self-Management Application in Left-Ventricular Assist Devices.

Despite major advancements in mechanical circulatory support, the self-management (SM) for patients with a left-ventricular assist device (LVAD) remains complex and challenging for patients and their caregivers. We have developed a mobile phone application (VAD Care App) to organize and simplify the LVAD SM process. This article describes the development and feasibility study of the app as an SM tool for LVAD patients and caregivers requiring support from ventricular assist device (VAD) coordinators. The specific aim was to evaluate the app's acceptability and usability and the users' competency. App features included an automated alert, data collection/reporting, and dynamic real-time interaction systems embedded in the LVAD SM process. Beta-testing of the prototype was completed by five adults. For the feasibility study, we employed a mixed-method descriptive research design involving nine patients and nine caregivers from two VAD centers in the Midwest. We asked them to use the app daily for more than 30 days and complete an app Evaluation Questionnaire and an interview. The questionnaire uses a five-point rating scale (1 = strongly disagree to 5 = strongly agree) evaluating usability, acceptability, and competency domains. Data generated from the questionnaires and interviews were analyzed with descriptive statistics and content analytic procedures. A total of 16 users (eight patients [all male] and eight caregivers [seven female]) aged 22 to 68 years completed the 30 day study. Median acceptability, usability, and competency scores were 4.6, 4.5, and 4.7, respectively. Based on the data, it is feasible for patients and caregivers to use an app as an LVAD SM tool warranting further research.

Low health literacy: Implications for managing cardiac patients in practice.

There are limited data on racial and ethnic disparities related to quality of life (QoL) and health literacy in adults with multiple cardiac conditions. This article evaluates the relationship between health literacy and QoL among patients with cardiac conditions in a multiethnic community in New York City.
