The measure of impact: Proposal of quality metrics for solid organ transplant pharmacy practice.

As healthcare continues its transition toward value-based care, it is increasingly important for transplant pharmacists to demonstrate their impact on patient care, health-related outcomes, and healthcare costs. Evidence-based quality and performance metrics are recognized as crucial tools for measuring the value of service. Yet, there is a lack of well-developed and agreed-upon specific metrics for many clinical pharmacy specialties, including solid organ transplantation. To address this need, a panel of transplant pharmacy specialists conducted a detailed literature review and engaged in several panel discussions to identify quality metrics to be considered for assessing the value of clinical pharmacy services provided to solid organ transplant recipients and living donors. The proposed metrics are based on the Donabedian model and are categorized to coincide with the typical phases of transplant care. The measures focus on key issues that arise in transplant recipients related to medication therapy, including adverse drug events, nonadherence, and clinical outcomes attributable to medication therapy management. This article proposes a comprehensive set of measures, any number of which transplant pharmacists can adopt and measure over time to objectively gauge the value of services they are providing to transplant recipients, the transplant center, and the overall healthcare system.

A systematic review of opioid use and multimodal strategies in solid organ transplant recipients and living donors.

The opioid epidemic has impacted analgesia in the postoperative period for solid organ transplant (SOT) donors and recipients. However, optimal pain management and opioid stewardship strategies have not been identified across this unique population. The purpose of this systematic review was to evaluate the impact of perioperative opioid use and to describe multimodal analgesic strategies to reduce opiate use in SOT recipients and living donors. A systematic review was conducted. Electronic searches were performed in Medline, Embase, Google Scholar, and Web of Science through December 31, 2021. Title and abstracts were screened. Relevant articles underwent full-text review. Literature was separated into effects of opioid exposure on post-transplant outcomes, recipient pain management strategies, and living donor pain management strategies. Search yielded 25,190 records, and 63 were ultimately included. The impact of opioid use on post-transplant outcomes was assessed in 19 publications. The risk of graft loss in pretransplant opioid users was assessed in six reports and was found to be higher in the majority (66%) of publications. Opioid minimization strategies were reported in 20 studies in transplant recipients. Twenty-four studies evaluated pain management strategies in living donors. Both populations used a combination of multimodal strategies to minimize opioid use throughout the hospitalization and on discharge. Opioids are associated with select negative outcomes in post-transplant recipients. To minimize their use while also maintaining appropriate analgesia, multimodal pain regimens should be considered in SOT recipients and donors.

The expanded role of the transplant pharmacist: A 10-year follow-up.

The role of the transplant pharmacist is recognized by transplant programs, governmental groups, and professional organizations as an essential part of the transplant multidisciplinary team. This role has evolved drastically over the last decade with the advent of major advances in the science of transplantation and the growth of the field, which necessitate expanded pharmacy services to meet the needs of patients. Data now exist within all realms of the phases of care for a transplant recipient regarding the utility and benefit of a solid organ transplant (SOT) pharmacist. Furthermore, governing bodies now have the opportunity to use Board Certification in Solid Organ Transplant Pharmacotherapy as a mechanism to identify and recognize specialty knowledge and expertise within the field of SOT pharmacotherapy. The purpose of this paper is to provide an overarching review of the current and future state of SOT pharmacy while also identifying major changes to the profession, forthcoming challenges, and expected areas of growth.

Implementation and results of a standardized process for identifying ambulatory pharmacy clinical outcome measures.

PURPOSE: Given the variation in clinical practice, a clinician-centric, standardized process to implement and validate clinical pharmacy outcome measures was developed. SUMMARY: Four specialty clinics with embedded clinic-based pharmacists underwent an iterative process to define, refine, and implement the build of electronic health record functionality for outcome measure data collection and reporting. Starting with a list of identified measures, clinic workgroups met to discuss each measure and identify gaps in measure implementation. Information technology experts created electronic documentation forms with discrete data and reports based on criteria specified by the clinic workgroups. Of 32 outcome measures identified as priorities for demonstrating pharmacists' impact in previous research, 29 were implemented for routine monitoring through this project. Implementation strategies included identification through existing reporting, development of discrete documentation tools within the electronic health record, and development of new reporting tools from available discrete data fields. Time to implementation decreased from the first to the last pilot clinic implementation, as demonstrated through a 9-day reduction in electronic documentation form development and 31-day reduction in report development turnaround time. CONCLUSION: A standardized and reproducible process was developed for the implementation of clinical pharmacy outcomes measures for 4 specialty clinics. The process was successfully utilized to develop measurable outputs for a variety of oncology and nononcology specialty disease states based upon multidisciplinary stakeholder input.

Safety and Efficacy of Early Post-Operative Intravenous Iron Replacement In Patients With HeartMate III Left Ventricular Assist Device.

BACKGROUND: While guidelines suggest intravenous (IV) iron to improve functional status and quality of life (QoL) in patients with NYHA class II-III heart failure (HF), continuous flow left ventricular assist device (CF-LVAD) recipients were not included in early IV iron studies. Our study compared outcomes between patients who did and did not receive IV iron during the index admission following Abbott HeartMate III™ (HM 3) CF-LVAD placement. METHODS: Thirty-three adult patients with a HM3 placed at our institution who received early post-operative IV iron (n = 20) or no IV iron replacement (n = 13) were compared. The co-primary outcomes were mean change in quality of life (by the Minnesota Living with Heart Failure Questionnaire [MLHFQ]) and 6-minute walk distance (6MWD) from baseline to first >90 day clinic follow-up. RESULTS: At first clinic follow-up there was no significant difference between the IV iron and no-IV iron groups in MLHFQ (-27 ± 38 vs -21 ± 41, P = .8822) or 6MWD (360 ± 740 vs 786 ± 722, P = .208). CONCLUSION: Patients receiving IV iron during index admission following HM3 implantation did not experience an improvement in quality of life or functional capacity when compared to those who did not receive IV iron.

Pharmacotherapy of chronic lung allograft dysfunction post lung transplantation.

BACKGROUND: Chronic lung allograft dysfunction (CLAD) remains the primary cause of death in lung transplant recipients (LTRs) despite improvements in immunosuppression management. Despite advances in knowledge regarding the pathogenesis of CLAD, treatments that are currently available are usuallyineffective and delay progression of disease at best.There are currently no evidence-based guidelines and minimal publications regarding the optimal treatment ofCLAD. OBJECTIVE: To complete a comprehensive review of the literature for the prevention and medical management of CLAD. METHODS: We identified the major domains of the medical management of CLAD and conducted a comprehensive search of PubMed and Embase databases to identify articles published from inception to December 2021 related to CLAD in LTRs. Studies published in English pertaining to the pharmacologic prevention and treatment of CLAD were included; highest priority was given to prospective, randomized, controlled trials if available. Prospective observational and retrospective controlled trials were prioritized next, followed by retrospective uncontrolled studies, case series, and finally case reports if the information was deemed to be pertinent. Reference lists of qualified publications were also reviewed to find any other publications of interest that were not found on initial search.In the absence of literature published in the aforementioned databases, additional articles were identified by reviewing abstracts presented at the International Society for Heart and Lung Transplantation and American Transplant Congress annual meetings between 2010-2021. CONCLUSION: CLAD should be identified as early as possible along with prompt intervention to optimize the possibility of stabilizing or improving lung function. More robust clinical data is needed to validate the use of all currently available and investigational treatment options for CLAD to identify the optimal pharmacotherapy management for this patient population.

Outcomes of Children with Fetal and Lactation Immunosuppression Exposure Born to Female Transplant Recipients.

Solid organ transplantation (SOT) is a lifesaving procedure for those with end-stage kidney, liver, heart, lung, and intestinal diseases, including females of childbearing age who wish to proceed with pregnancy following transplantation. While there is clear risk associated with use of mycophenolate during pregnancy, the risks associated with use of other immunosuppressant agents are less well understood, and the timing of use in pregnancy may be pertinent when considering the risk versus benefit for individual patients. In addition to overall fetal outcomes, including gestational age, birth weight, and mortality, this review summarizes published literature on additional complications that have been examined in association with maternal use during pregnancy and postpartum while breastfeeding. Compared with non-transplant pregnancies, pregnancies in transplant recipients are associated with lower birth weight and earlier gestational age. Effects associated with particular immunosuppressant agents in the infant include renal dysfunction from calcineurin inhibitors, myelosuppression from azathioprine, and decreased circulating immune cells with several agents. However, these effects are noted to primarily be transient, though the decrease in immune cells may predispose the infant to increased infectious complications in the first year of life. Utilizing relative infant dose estimations, nearly all commonly utilized immunosuppressants are likely safe during breastfeeding given the limited exposure to the infant.

Poor tolerability of cystic fibrosis transmembrane conductance regulator modulator therapy in lung transplant recipients.

Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) is a highly effective therapy for patients with cystic fibrosis (CF) with potential benefits in lung transplant recipients (LTRs) for extrapulmonary CF manifestations; however, tolerability and efficacy in this population are largely unknown. We report our experience with ELX/TEZ/IVA in LTRs for extrapulmonary complications of CF including tolerability, drug-drug interactions, and therapeutic benefit. All LTRs at a single center initiated on ELX/TEZ/IVA were reviewed. Adverse events and patient-reported outcomes attributed to ELX/TEZ/IVA were documented. Pulmonary function, tacrolimus requirements in mg/kg/dl, body mass index (BMI), and reason for initiation were assessed at the initiation of ELX/TEZ/IVA, and at 12 months post-initiation or at the time of discontinuation for those in whom therapy was discontinued. Thirteen LTRs were initiated on ELX/TEZ/IVA at a mean of 115 ± 92 months post-transplant. All were initiated on ELX/TEZ/IVA for sinus or sinus and gastrointestinal CF manifestations. Five (38.4%) patients discontinued therapy due to declining pulmonary function (2/5, 40%), mood disturbances (2/5, 40%), or lack of benefit (1/5, 20%). Of the eight patients who remain on ELX/TEZ/IVA, four reported adverse effects and three LTRs temporarily held therapy. Six (46.2%) LTRs reported improvement in sinus symptoms, while four (30.7%) reported improved gastrointestinal symptoms. Weight declined in the cohort overall. Tacrolimus dose requirements decreased following initiation of ELX/TEZ/IVA therapy, with a 50% decline in dose requirements observed. In our experience, ELX/TEZ/IVA in LTRs is poorly tolerated with modest perceived extrapulmonary benefit and a significant effect on tacrolimus dose requirements. More data are needed to determine the benefits of ELX/TEZ/IVA therapy in LTRs.

Assessment of the prevalence of burnout and well-being in solid organ transplant pharmacists.

BACKGROUND: Solid organ transplant (SOT) pharmacist burnout and well-being has not been described. METHODS: A survey of SOT pharmacists was distributed to transplant pharmacy organization listservs. Burnout was assessed with the full 22 item Maslach Burnout Inventory Human Services Survey for Medical Personnel (MBI-HSS-MP) and well-being was assessed with the Mayo Well-Being Index (WBI). Logistic multivariate regression was constructed to identify risk factors for a composite burnout assessment. RESULTS: In total, 230 responses were included (estimated response rate 36.2%). Survey participants were predominantly Caucasian (80.4%), female (79.1%), married/partnered (67.4%), and were within the first 5 years of practice (32.2%) as clinical pharmacist/specialists (87%). According to the MBI-HSS-MP, 63% met criteria for burnout. Comparing the groups with or without burnout, low quality of life (40.4% vs. 9.5%; P<.001), extreme fatigue (52.1% vs. 19%; P<.001), and likelihood of leaving the job for reasons other than retirement (38.5% vs. 10.7%; P<.001) were more common. The incidence of SOT pharmacists with WBI scores ≥ 5 (decreased well-being) was 26.5%. Among clinical pharmacists, risk factors for burnout included > 10 h per week of clinical duties outside of transplant (OR 2.669, P = .021) and extreme fatigue (OR 3.473, P<.001). CONCLUSIONS: Pharmacist burnout in SOT practice was similar to that reported in various pharmacy specialties (53-61%), which impacts clinical workforce retention and personal well-being.

The Clinical Conundrum of Cannabis: Current Practices and Recommendations for Transplant Clinicians: An Opinion of the Immunology/Transplantation PRN of the American College of Clinical Pharmacy.

Cannabis, or marijuana, comprises many compounds with varying effects. It has become a treatment option for chronic diseases and debilitating symptoms, and evidence suggests that it has immunomodulatory and antiinflammatory properties. Transplant centers are more frequently facing issues about cannabis, as indications and legalization expand. As of February 2020, 33 states and the District of Columbia have legalized medical cannabis, and 14 have legalized recreational cannabis. Moreover, 8 states have passed legislation prohibiting the denial of transplant listing solely based on cannabis use. Studies demonstrate the potential for significant pharmacokinetic and pharmacodynamic interactions between cannabis and immunosuppression. Additionally, safety concerns include increased risk of myocardial infarction, ischemic stroke, tachyarrhythmias, malignancy, neurocognitive deficits, psychosis, other neuropsychiatric disorders, cannabis use disorder, respiratory symptoms, and infection. A recent retrospective database study found a negative association between documented cannabis use disorder and graft survival, but little additional evidence exists evaluating this relationship. In the absence of robust clinical data, transplant centers need a clear, reasoned, and systematic approach to cannabis. The results of our national survey, unfortunately, found little consensus among institutions. As both recreational and medicinal cannabis become more ubiquitous nationwide, transplant centers will need to develop comprehensive policies to address its use.

Pharmacotherapy for durable left ventricular assist devices.

Left ventricular assist devices (LVADs) have revolutionized the care of patients with advanced heart failure, yet still require concomitant medications in order to achieve the best possible clinical outcomes. Since the outset of routine placement of durable, continuous-flow LVADs, much of the medication management of these patients to date has been based on International Society of Heart and Lung Transplantation (ISHLT) guidance, most recently published in 2013. Since 2013, numerous multidisciplinary pharmacotherapy publications have increased the LVAD community's understanding of best practices with respect to medications. We identified the major domains of LVAD medication management and conducted a comprehensive search of US National Library of Medicine MEDLINE® database using keywords chosen to identify medication-related publications of significance dated 2013 or later. Trials pertaining to the HeartMate II™ and the HeartMate™ 3 LVADs (Abbott, Chicago, IL) and the HeartWare™ HVAD™ System (Medtronic, Minneapolis, MN) were chosen for inclusion. Highest priority for inclusion was given to prospective, randomized, controlled studies. Absent these, controlled trials (retrospective or prospective observational) were given next-highest consideration, followed by retrospective uncontrolled studies, and finally case series. Reference lists of qualified publications were reviewed to find any other publications of interest that were not discovered on initial search. Case reports were generally excluded, except where the insight gained was deemed to be uniquely pertinent. This document serves to provide a comprehensive review of the current understanding of optimal medication management in patients with durable, continuous-flow LVADs.

The Effect of Tacrolimus Trough Variability on Kidney Transplant Outcomes.

PURPOSE: Variability in tacrolimus levels has been associated with increased rejection, graft loss, and de novo donor-specific antibody (dnDSA) development in kidney transplant recipients (KTRs); however, limited data on alemtuzumab induction or infection exist. We sought to determine the impact of tacrolimus variability in KTRs on dnDSAs, graft outcomes, and infections 3 years posttransplant after alemtuzumab induction. METHODS: Adult KTRs from January 1, 2013, to December 31, 2017, receiving alemtuzumab and tacrolimus-based immunosuppression at a single center were included. Tacrolimus variability was calculated using coefficient of variability (CV), and high CV was defined as ≥30%. Graft and infectious outcomes were assessed between high and low CV groups. RESULTS: Two hundred fourteen KTRs were included. The median tacrolimus CV from 0 to 3 months and from 3 to 12 months was 28.1% and 25.8%, respectively. Recipients with high CV had decreased glomerular filtration rate at 3 and 12 months (67.7 ± 35.48 vs 80.7 ± 29.3, P = .01 and 70.9 ± 35.4 vs 83.3 ± 30.2, P = .015). High CV was also associated with increased cytomegalovirus viremia and disease (19.6% vs 9.3%, P = .046 and 6.4% vs 17.9%, P = .015). No difference in biopsy-proven acute rejection, survival, or dnDSA development at 3 years was observed. CONCLUSIONS: High tacrolimus variability was associated with significantly reduced graft function and increased cytomegalovirus viremia and disease but not biopsy-proven acute rejection, survival, or dnDSA development.

Report from the 2018 consensus conference on immunomodulating agents in thoracic transplantation: Access, formulations, generics, therapeutic drug monitoring, and special populations.

In 2009, the International Society for Heart and Lung Transplantation recognized the importance and challenges surrounding generic drug immunosuppression. As experience with generics has expanded and comfort has increased, substantial issues have arisen since that time with other aspects of immunomodulation that have not been addressed, such as access to medicines, alternative immunosuppression formulations, additional generics, implications on therapeutic drug monitoring, and implications for special populations such as pediatrics and older adults. The aim of this consensus document is to address critically each of these concerns, expand on the challenges and barriers, and provide therapeutic considerations for practitioners who manage patients who need to undergo or have undergone cardiothoracic transplantation.

The 2018 ISHLT/APM/AST/ICCAC/STSW Recommendations for the Psychosocial Evaluation of Adult Cardiothoracic Transplant Candidates and Candidates for Long-term Mechanical Circulatory Support.

The psychosocial evaluation is well-recognized as an important component of the multifaceted assessment process to determine candidacy for heart transplantation, lung transplantation, and long-term mechanical circulatory support (MCS). However, there is no consensus-based set of recommendations for either the full range of psychosocial domains to be assessed during the evaluation, or the set of processes and procedures to be used to conduct the evaluation, report its findings, and monitor patients' receipt of and response to interventions for any problems identified. This document provides recommendations on both evaluation content and process. It represents a collaborative effort of the International Society for Heart and Lung Transplantation (ISHLT) and the Academy of Psychosomatic Medicine, American Society of Transplantation, International Consortium of Circulatory Assist Clinicians, and Society for Transplant Social Workers. The Nursing, Health Science and Allied Health Council of the ISHLT organized a Writing Committee composed of international experts representing the ISHLT and the collaborating societies. This Committee synthesized expert opinion and conducted a comprehensive literature review to support the psychosocial evaluation content and process recommendations that were developed. The recommendations are intended to dovetail with current ISHLT guidelines and consensus statements for the selection of candidates for cardiothoracic transplantation and MCS implantation. Moreover, the recommendations are designed to promote consistency across programs in the performance of the psychosocial evaluation by proposing a core set of content domains and processes that can be expanded as needed to meet programs' unique needs and goals.

The Role of mTOR Inhibitors in the Management of Viral Infections: A Review of Current Literature.

Viruses are the leading cause of infections after solid organ transplant. The antiviral properties of mammalian target of rapamycin inhibitors (mTORis) have been ascribed to a variety of mechanisms and historical data have supported their use over other immunosuppressants for a myriad of viruses. Herein, we summarize the most current data to highlight the role of mTORis in the management of viral infections after solid organ transplant. The mTORis play a clear role in the management of cytomegalovirus, and have data supporting their potential use for BK virus and human herpesvirus 8-related Kaposi sarcoma. No data definitively supports mTORis for use in Epstein-Barr virus-mediated posttransplant lymphoproliferative disorder or hepatitis C virus viral replication. Although theoretically an advantageous therapy for hepatitis C virus-related liver allograft fibrosis and human immunodeficiency virus, mTORi use specifically for these indications is less attractive with modern treatments currently available. Data surrounding mTORi efficacy in preventing rejection, and their toxicity profile must be balanced with their potential antiviral effects in combination with patient-specific factors.

Pharmacologic Considerations for Solid Organ Transplant Recipients Who Become Pregnant.

Females of childbearing age represent a large population of solid organ transplant recipients. With fertility commonly restored after transplantation, the possibility of pregnancy becomes a reality for many patients. Since the first published report of a successful pregnancy after solid organ transplantation in 1963, the number of pregnancies reported for female organ recipients has continued to increase. Despite this, information on the management of immunosuppression during pregnancy is limited, and a summary of these data is lacking in the literature. In addition to the many pharmacotherapeutic challenges in this unique patient population, physiologic changes in the peripartum period significantly affect the pharmacokinetics and pharmacodynamics of commonly used immunosuppressive agents. These changes, as well as the adverse effects and safety concerns of medications, must all be taken in to consideration to optimize outcomes for both mother and baby. In this review, we provide clinicians caring for female solid organ transplant recipients who wish to become pregnant or who are currently pregnant with a comprehensive review of maternal and fetal risks of pregnancy after transplantation. In addition, pharmacokinetic and pharmacodynamic changes of pregnancy will be discussed, and a summary of data regarding optimal immunosuppression management during pregnancy will be presented.

Device-Related Thrombosis in Continuous-Flow Left Ventricular Assist Device Support.

Advanced heart failure therapy has been revolutionized with the advent of continuous-flow ventricular assist devices (CF-LVADs) which have improved both survival and quality of life. Despite this, support with CF-LVADs is frequently complicated, with 70% of recipients experiencing a major complication in the first year of durable support. The most concerning of these complications to emerge is device-related thrombosis, which is associated with increased morbidity and mortality. Pathophysiology and diagnosis are multifaceted and complex, with pump-specific and patient-specific factors to be considered. Incidence estimates are evolving with increases seen in the past 2 years compared with earlier implant data. Evidence for treatment is limited to case series and reports, which are subject to significant publication bias. Finally, appropriate primary and secondary prophylaxis is imprecise with multiple antiplatelet and antithrombotic strategies described. This review seeks to summarize the current literature surrounding the pathophysiology, diagnosis, and management of thrombosis in CF-LVAD recipients.
