Efficient measurement of multiple ventricular assist device patient-reported outcomes: Creation of a 20-item profile from the MCS A-QOL study.

BACKGROUND: Patient-reported outcome (PRO) measures of distinct concepts are often put together into patient profile assessments. When brief, profile assessments can decrease respondent burden and increase measure completion rates. In this report, we describe the creation of 5 self-reported 4-item short forms and the Mechanical Circulatory Support: Measures of Adjustment and Quality of Life (MCS A-QOL) 20-item profile to assess PROs specific to adjustment and health-related quality of life (HRQOL) among patients who undergo left ventricular assist device (LVAD) implantation. METHODS: Using a cross-sectional sample of patients (n = 620) who underwent LVAD implantation at 12 U.S. sites or participated in the MyLVAD.com support group, we created 5 4-item short forms: Satisfaction with Treatment, ventricular assist device (VAD) Team Communication, Being Bothered by VAD Self-care and Limitations, Self-efficacy Regarding VAD self-care, and Stigma, which we combined into a 20-item profile. Analyses included intercorrelations among measures, Cronbach's alpha (i.e., internal consistency reliability)/score-level-specific reliability, and construct validity. RESULTS: The 620 patients were mean age = 57 years, 78% male, 70% White, and 56% on destination therapy LVADs. Intercorrelations among the 5 4-item measures were low to moderate (≤0.50), indicating they are associated yet largely distinct, and correlations with calibrated measures and 6-item short forms were ≥0.76, indicating their ability to reflect full-item bank scores. Internal consistency reliability for the 5 4-item short forms ranged from acceptable (≥0.70) to good (≥0.80). Construct validity was demonstrated for these measures. CONCLUSIONS: Our 5 4-item short forms are reliable and valid and may be used individually or together as a 20-item profile to assess adjustment and HRQOL in patients who undergo LVAD implantation.

Increasing heart transplant donor pool by liberalization of size matching.

BACKGROUND: The heart transplant (HT) guidelines recommendation to match recipient and donors within 30% of body weight lacks a strong evidence base and is not well established in patients bridged to transplant with left ventricular assist devices (LVAD). In light of the scarcity of donor hearts, we investigated the effect of size mismatch on hemodynamics, one-year survival and length of stay (LOS) following HT. METHODS: Single-center retrospective analysis of consecutive HT patients from April 2007 to September 2017. Recipients were divided into 3 cohorts based on donor-to-recipient weight ratio (DRWR): (1) undersized (<0.7), (2) size-matched, (0.7-1.3); (3) oversized (>1.3). RESULTS: 288 consecutive patients were identified (mean age 53 ± 11 years; 76% male), 46 were undersized (0.61 ± 0.05), 210 size-matched (0.94 ± 0.16), and 32 oversized (1.65 ± 0.38). There was no significant difference in donor left ventricular end diastolic diameter (LVEDD) between the 3 groups (p = 0.11). The donor/recipient (D/R) predicted heart mass (PHM) was lowest in the undersized group (0.92 ± 0.13). There were no significant differences in 1-year survival in the overall and LVAD cohort (p = 0.65 and 0.59, respectively). Neither donor LVEDD nor D/R PHM differed among survivors or non-survivors. LOS was longer in the undersized group than the size-matched cohort (p = 0.004). The undersized group had hearts with the highest filling pressures and lowest cardiac index at 1 week among the remaining groups (p = 0.009, 0.017, and p = 0.05, respectively). There were no clinically significant differences in hemodynamics at 1 or 6 months. CONCLUSIONS: HT undersizing affects hemodynamics early but not later in the course and does not impact 1-year survival. The liberalization of size matching may increase the HT donor pool significantly.

Increase in short-term risk of rejection in heart transplant patients receiving granulocyte colony-stimulating factor.

BACKGROUND: Neutropenia is a significant adverse event after heart transplantation (HT) and increases infection risk. Granulocyte colony-stimulating factor (G-CSF) is commonly used in patients with neutropenia. In this work, we assessed the adverse effects of G-CSF treatment in the setting of a university hospital. METHODS: Data on HT patients from January 2008 to July 2016 were reviewed. Patients who received G-CSF were identified and compared with patients without a history of therapy. Baseline characteristics, rejection episodes, and outcomes were collected. Data were analyzed by incidence rates, time to rejection and survival were analyzed using Kaplan-Meier curves, and odds ratios were generated using logistic regression analysis. RESULTS: Two hundred twenty-two HT patients were studied and 40 (18%) received G-CSF for a total of 85 total neutropenic events (0.79 event/patient year). There were no differences in baseline characteristics between the groups. In the 3 months after G-CSF, the incidence rate of rejection was 0.067 event/month. In all other time periods considered free of G-CSF effect, the incidence rate was 0.011 event/month. This rate was similar to the overall incidence rate in the non-GCSF group, which was 0.010 event/month. There was a significant difference between the incidence rates in the G-CSF group at 0 to 3 months after G-CSF administration and the non-GCSF group (p = 0.04), but not for the other time periods (p = 0.5). Freedom from rejection in the 3 months after G-CSF administration was 87.5% compared with 97.5% in the non-GCSF group (p = 0.006). CONCLUSIONS: G-CSF administration was found to be associated with significant short-term risk of rejection. This suggests the need for increased surveillance during this time period.

Balloon Pumps Inserted via the Subclavian Artery: Bridging the Way to Heart Transplant.

Intra-aortic balloon pumps have traditionally been inserted via the femoral artery, limiting patients' activity and exposing patients to complications of immobility. For patients awaiting cardiac transplant, these complications may threaten a successful outcome, or at the least, complicate recuperation after transplant. A novel approach to insertion of balloon pumps via the subclavian artery is presented here, including routine nursing care, complications and related nursing actions, and experience with and advantages of this method. A team approach to care of these patients, including rehabilitation and exercise protocols, is recommended.

Interdisciplinary Pain Education: Moving From Discipline-Specific to Collaborative Practice.

BACKGROUND: Pain is a common symptom reported by hospitalized patients with cancer. Cancer pain management requires an interdisciplinary approach for quality patient care. Although the literature suggests that most cancer pain can be managed with available treatments, many patients continue to experience pain even with opioid prescriptions. Implementation of evidence-based guidelines, such as the National Comprehensive Cancer Network's guidelines for adult cancer pain, promotes collaboration across disciplines and enhances patient care. OBJECTIVES: This article reports the development, implementation, and evaluation of an interdisciplinary pain education program, Oncology Provider Pain Training (OPPT), to improve clinician knowledge and promote collaborative practice. METHODS: The Kirkpatrick Model was used to design the OPPT program. A multifaceted training approach was used to accommodate the various needs of potential participants. Interdisciplinary educational sessions were held during a one-month period. Knowledge gained, learner reaction, and satisfaction were evaluated using predetermined benchmarks one month following program completion. FINDINGS: Satisfaction benchmarks for content, teaching materials, and presenter were met. Although the knowledge gained benchmark was not met, substantial progress toward achievement was made. Additional modifications include increasing discipline-specific content and focus on pain pathophysiology and addressing time constraints. Inconsistent technology adoption across disciplines may have a negative effect on interdisciplinary educational efforts.

Adult cardiothoracic transplant nursing: an ISHLT consensus document on the current adult nursing practice in heart and lung transplantation.

BACKGROUND: The role of nurses in cardiothoracic transplantation has evolved over the last 25 years. Transplant nurses work in a variety of roles in collaboration with multidisciplinary teams to manage complex pre- and post-transplantation issues. There is lack of clarity and consistency regarding required qualifications to practice transplant nursing, delineation of roles and adequate levels of staffing. METHODS: A consensus conference with workgroup sessions, consisting of 77 nurse participants with clinical experience in cardiothoracic transplantation, was arranged. This was followed by subsequent discussion with the ISHLT Nursing, Health Science and Allied Health Council. Evidence and expert opinions regarding key issues were reviewed. A modified nominal group technique was used to reach consensus. RESULTS: Consensus reached included: (1) a minimum of 2 years nursing experience is required for transplant coordinators, nurse managers or advanced practice nurses; (2) a baccalaureate in nursing is the minimum education level required for a transplant coordinator; (3) transplant coordinator-specific certification is recommended; (4) nurse practitioners, clinical nurse specialists and nurse managers should hold at least a master's degree; and (5) strategies to retain transplant nurses include engaging donor call teams, mentoring programs, having flexible hours and offering career advancement support. Future research should focus on the relationships between staffing levels, nurse education and patient outcomes. CONCLUSIONS: Delineation of roles and guidelines for education, certification, licensure and staffing levels of transplant nurses are needed to support all nurses working at the fullest extent of their education and licensure. This consensus document provides such recommendations and draws attention to areas for future research.

Isolated heart transplantation for familial transthyretin (TTR) V122I cardiac amyloidosis.

Transthyretin (TTR) cardiac amyloidosis is characterized by deposition of either mutant or wild type TTR amyloid protein in the myocardium ultimately leading to progressive cardiomyopathy and heart failure. The most common TTR gene mutation that leads to TTR cardiac amyloidosis is the valine-to-isoleucine substitution at position 122 (V122I or Ile122). Currently, the only definitive treatment suggested for mutant TTR cardiac amyloidosis is the combined or sequential liver-heart transplantation in eligible patients, since liver is the source of TTR production. Here, we report a case of heterozygous Val122L mutated TTR-related cardiac amyloidosis treated with isolated heart transplantation with no recurrence of amyloid in the cardiac allograft and no systemic abnormalities 5 years after heart transplantation.
