A High-Fidelity, Tissue-Based Simulation for Cardiac Transplantation.

Several operations in cardiothoracic surgery have been accurately modeled with tissue-based simulations. These have been shown to be beneficial in the training of residents. Cardiac transplantation has not been simulated. We describe a high-fidelity, tissue-based simulation that can be used to teach trainees to perform a cardiac transplant. We modified the existing Ramphal Cardiac Surgery Simulator to accommodate cardiac transplantation. An attending cardiac surgeon successfully performed the simulated transplant, demonstrating each of the component tasks of the operation. We believe our simulation will enhance the training of cardiothoracic surgery residents.

Stakeholder perspectives of the clinical utility of pharmacogenomic testing in solid organ transplantation.

Aims: To assess stakeholder perspectives regarding the clinical utility of pharmacogenomic (PGx) testing following kidney, liver, and heart transplantation. Methods: We conducted individual semi-structured interviews and focus groups with kidney, liver, and heart transplantation patients and providers. We analyzed the qualitative data to identify salient themes. Results: The study enrolled 36 patients and 24 providers. Patients lacked an understanding about PGx, but expressed interest in PGx testing. Providers expressed willingness to use PGx testing, but reported barriers to implementation, such as lack of knowledge, lack of evidence demonstrating clinical utility, and patient healthcare burden. Conclusion: Patient and provider educational efforts, including foundational knowledge, clinical evidence, and applications to patient care beyond just immunosuppression, may be useful to facilitate the use of PGx testing in transplant medicine.

Optimizing Surgical Skills in Cardiac Surgery Residents with Cardiac Transplant in the High-Fidelity Porcine Model.

OBJECTIVES: Simulation is a pivotal tool within cardiac surgery to facilitate learner growth and skill acquisition. There are many methods of simulation and it is possible to develop and implement new curricula incorporating these modalities. The objective of this paper is to describe the feasibility of a high-fidelity cardiac transplant simulation curriculum for surgical residents. METHODS: Our simulation setting was the Animal Resource Center at the University of Calgary. It was set up with 4 separate operating rooms, 2 for donor heart retrievals and 2 for heart implantations. This was done to allow 2 learners to participate with each animal, replicating the true intraoperative environment. Our teaching sessions were facilitated by 2 surgeons experienced in cardiac transplantation. In addition, we had support staff including multiple perfusionists, nurses, and anesthesia technologists. RESULTS: The curriculum was evaluated from many perspectives in real time throughout the simulation as well as afterward in posttest qualitative interviews with all participants. The residents readily identified the acquisition of and increased proficiency in specifically targeted surgical skills. In addition, the residents were able to practice communication, collaboration, and management. Furthermore, the simulation session and our debriefings contributed significantly to fostering a team approach. CONCLUSIONS: The pig is an excellent preclinical model for acquiring and developing the skills necessary for human cardiac transplantation. The residents partaking in the curriculum were satisfied with the learning they received and saw value in the swine transplant curriculum. The overall curriculum was cost-effective, due to the low overall operating costs associated with it.

'Making the Invisible Visible': an audience response to an art installation representing the complexity of congenital heart disease and heart transplantation.

The arts can aid the exploration of individual and collective illness narratives, with empowering effects on both patients and caregivers. The artist, partly acting as conduit, can translate and re-present illness experiences into artwork. But how are these translated experiences received by the viewer-and specifically, how does an audience respond to an art installation themed around paediatric heart transplantation and congenital heart disease? The installation, created by British artist Sofie Layton and titled Making the Invisible Visible, was presented at an arts-and-health event. The piece comprised three-dimensional printed medical models of hearts with different congenital defects displayed under bell jars on a stainless steel table reminiscent of the surgical theatre, surrounded by hospital screens. The installation included a soundscape, where the voice of a mother recounting the journey of her son going through heart transplantation was interwoven with the voice of the artist reading medical terminology. A two-part survey was administered to capture viewers' expectations and their response to the piece. Participants (n=125) expected to acquire new knowledge around heart disease, get a glimpse of patients' experiences and be surprised by the work, while after viewing the piece they mostly felt empathy, surprise, emotion and, for some, a degree of anxiety. Viewers found the installation more effective in communicating the experience of heart transplantation than in depicting the complexity of cardiovascular anatomy (p<0.001, z=7.56). Finally, analysis of open-ended feedback highlighted the intimacy of the installation and the privilege viewers felt in sharing a story, particularly in relation to the soundscape, where the connection to the narrative in the piece was reportedly strengthened by the use of sound. In conclusion, an immersive installation including accurate medical details and real stories narrated by patients can lead to an empathic response and an appreciation of the value of illness narratives.

Recommendations from the Association for European Paediatric and Congenital Cardiology for clinical training in paediatric heart failure and transplantation.

Advanced medical and surgical treatment of heart failure and management of patients following heart transplantation is an emerging area. Treatment options at various levels are becoming available in an increasing number of countries. This rapidly evolving field involves a complex multi-disciplinary approach with a number of complementary medical and surgical strategies, including pharmacotherapy, structural cardiac interventions, electrophysiological optimisation, mechanical circulatory support, and heart transplantation. Furthermore, the importance of psycho-social support and care of patients and their families cannot be overstated. The aforementioned challenges and dynamics of new developments require guidance for core and advanced medical training in heart failure and transplantation. The Association for European Paediatric and Congenital Cardiology working group "pulmonary hypertension, heart failure and transplantation" has produced this document as an expert consensus statement; however, all recommendations must be considered and applied in the context of the local and national infrastructure and legal regulations.

Surgical Thoracic Transplant Training: Super Fellowship-Is It Super?

OBJECTIVE: The quality of training provided to thoracic transplant fellows is a critical step in the care of complex patients undergoing transplant. The training varies since it is not an accreditation council for graduate medical education accredited fellowship. METHOD: A total of 104 heart or lung transplant program directors throughout the United States were sent a survey of 24 questions focusing on key aspects of training, fellowship training content and thoracic transplant job satisfaction. Out of the 104 programs surveyed 45 surveys (43%) were returned. RESULTS: In total, 26 programs offering a transplant fellowship were included in the survey. Among these programs 69% currently have fellows of which 56% are American Board of Thoracic Surgery board eligible. According to the United Network for Organ Sharing (UNOS) requirements, 46% of the programs do not meet the requirements to be qualified as a primary heart transplant surgeon. A total of 23% of lung transplant programs also perform less than the UNOS minimum requirements. Only 24% have extra-surgical curriculum. Out of the participating programs, only 38% of fellows secured a job in a hospital setting for performing transplants. An astounding 77% of replies site an unpredictable work schedule as the main reason that makes thoracic transplant a less than favorable profession among new graduates. Long hours were also a complaint of 69% of graduates who agreed that their personal life is affected by excessive work hours. CONCLUSION: Annually, almost half of all thoracic transplant programs perform fewer than the UNOS requirements to be a primary thoracic surgeon. This results in a majority of transplant fellows not finding a suitable transplant career. The current and future needs for highly qualified thoracic transplant surgeons will not be met through our existing training mechanisms.

The effectiveness of interventions in managing treatment adherence in adult heart transplant patients: a systematic review.

BACKGROUND: Over the past 20 years, solid organ transplantation has evolved from experimental treatments to an effective alternative for the treatment of various diseases, including heart failure. Treatment non-adherence is a limiting factor for the success of heart transplants. A systematic review of the evidence is needed to examine the effectiveness of interventions for managing adherence to treatment in heart transplant patients. OBJECTIVE: The primary objective of this systematic review was to synthesize the best available evidence regarding interventions for managing adherence to pharmacological and non-pharmacological treatments in heart/heart-lung transplant patients. INCLUSION CRITERIA: This review considered primary studies that included patients 18 years old or older, who had undergone heart or heart-lung transplantation (regardless of gender, ethnicity, comorbidities or whether they had received other treatments or not) who were receiving pharmacological and non-pharmacological treatments.This review considered studies that evaluated the effectiveness of interventions in managing adherence to pharmacological or non-pharmacological treatments among adult heart/heart-lung transplant patients. Primary studies comparing standard care with any type of intervention to maintain treatment adherence were considered.This review considered any experimental study design including randomized controlled trials; other research designs, such as non-randomized controlled trials and before and after studies, were also considered for inclusion.The primary outcome considered was patient adherence to pharmacological or non-pharmacological treatments by means of objective or self-report assessment. SEARCH STRATEGY: Published and unpublished studies in English, Portuguese and Spanish were searched in electronic databases. Searches were completed in January 2014. METHODOLOGICAL QUALITY: Two independent reviewers, using the standardized critical appraisal instruments from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument, assessed methodological quality. DATA EXTRACTION: Data were extracted using the standardized data extraction tool from Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. DATA SYNTHESIS: Statistical pooling was not possible due to substantial heterogeneity of the studies; therefore data were presented as a narrative summary. RESULTS: Three quasi-experimental studies were included in this review. One study found that a dose reduction of immunosuppressive medications from a twice-daily to a once-daily regimen had a positive impact on treatment adherence; one found no significant difference in treatment adherence between patients who received educational intervention conducted in a teaching laboratory and those who received standard care; the third one also reported no significant difference in outcomes between a multifaceted intervention consisting of internet-based interactive workshops and standard care. CONCLUSIONS: The current best evidence to guide decisions regarding interventions to manage treatment adherence in heart transplant patients is limited. There is weak evidence that psycho-educational interventions (other than the standard care) has a positive impact on adherence and that decreasing the complexity of the treatment regimen by reducing the daily dose of the immunosuppressant drug improves adherence in heart transplant patients.

Achieving Accreditation Council for Graduate Medical Education duty hours compliance within advanced surgical training: a simulation-based feasibility assessment.

BACKGROUND: Certain operative cases occur unpredictably and/or have long operative times, creating a conflict between Accreditation Council for Graduate Medical Education (ACGME) rules and adequate training experience. METHODS: A ProModel-based simulation was developed based on historical data. Probabilistic distributions of operative time calculated and combined with an ACGME compliant call schedule. RESULTS: For the advanced surgical cases modeled (cardiothoracic transplants), 80-hour violations were 6.07% and the minimum number of days off was violated 22.50%. There was a 36% chance of failure to fulfill any (either heart or lung) minimum case requirement despite adequate volume. CONCLUSIONS: The variable nature of emergency cases inevitably leads to work hour violations under ACGME regulations. Unpredictable cases mandate higher operative volume to ensure achievement of adequate caseloads. Publically available simulation technology provides a valuable avenue to identify adequacy of case volumes for trainees in both the elective and emergency setting.

Estimating minimum program volume needed to train surgeons: when 4 × 15 really equals 90.

INTRODUCTION: Work-hour restrictions have decreased flexibility in scheduling and reduced exposure to certain operative cases. These restrictions may affect a resident's ability to meet certification requirements, particularly for rare, unscheduled cases (e.g., cardiothoracic transplants). We developed a computer-based simulation model using variables such as case volume and program size to demonstrate the influence of these factors on the likelihood of certifying a set of residents on rare cases. METHODS: We built a simulator to predict the probability of attaining certification for surgical residents, using cardiothoracic transplants as a test case. Inputs to the model included operating times, call schedules, and procurement travel times, as well as information on the distribution of times between transplants. RESULTS: We simulated 100 years of schedules using our current system parameters of an average of 33 heart and 31 lung transplants per year, and assuming an Accreditation Council for Graduate Medical Education-compliant daily-rotating call schedule. Despite having enough transplants to certify all residents for lungs if all opportunities were distributed equally among residents, the certification rate achieved when constrained by arrival time (and call schedules) and work restrictions was only 55%. Our calculations show that meeting minimum transplant-certification requirements for all residents would require at least 1.5 times the expected number of annual transplants. CONCLUSIONS: Our model enables analysis of a given program's ability to certify its residents based on program size and volume. These results could be used to design alternative scheduling paradigms to improve certification rates, without requiring reductions in certification requirements or program size.

Setting the stage for development of a program for adolescent heart transplant recipients to transition to adult providers: An integrative review of the literature.

PURPOSE: This integrative review of the literature was undertaken to determine if there was a body of knowledge to support a transition program in an adolescent heart transplant population. CONCLUSIONS: No studies were found involving a heart transplant transition program for adolescents. A literature review for transition in other chronic illness areas was undertaken. Youth with chronic illness are inadequately prepared to transfer to adult providers. Transition programs should be developed. These programs should be tailored to suit individual needs. They should teach disease knowledge and encourage participation in self-management skills. Participation in a transition program improved patients' quality of life and improved their knowledge about their disease. PRACTICE IMPLICATIONS: Nurses are in a unique position with chronically ill adolescents to promote positive behaviors at every interaction. Encouraging self-management behaviors will support these youth as they prepare to become adults.

Murine heterotopic heart transplant technique.

It is now over forty years since this technique was first reported by Corry, Wynn and Russell. Although it took some years for other labs to become proficient in and utilize this technique, it is now widely used by many laboratories around the world. A significant refinement to the original technique was developed and reported in 2001 by Niimi. Described here are the techniques that have evolved over more than a decade in the hands of three surgeons (Plenter, Grazia, Pietra) in our center. These techniques are now being passed on to a younger generation of surgeons and researchers. Based largely on the Niimi experience, the procedures used have evolved in the fine details - details which we will endeavor to relate here in such a way that others may be able to use this very useful model. Like Niimi, we have found that a video aid to learning is a priceless resource for the beginner.

Recently accepted for the waiting list for heart or lung transplantation - patients' experiences of information and support.

The aim of the study was to describe the patients' experiences of the information and support they received after being placed on the waiting list for a heart or lung transplant. The design was qualitative, and the critical incident technique was used. Incidents were collected via interviews with 21 patients. A total of 357 important events, both positive and negative, were identified and divided into two main groups: Body and mind and Information and support. The following subgroups emerged: chronic illness affects the patients, attitudes towards the future, impact of information, support from public organizations, and support from the private sphere. The patients showed knowledge of and involvement in the upcoming transplantation, which indicates that healthcare professionals managed to convey information and support effectively. By identifying the importance of factors such as body and mind and information and support for patients recently accepted for heart or lung transplantation, healthcare professionals are able to make specific improvements in the information and support that they provide. An important implication is to enhance the knowledge regarding transplant patients in other institutions and improve cooperation. Specific support programs to assist patients who have dependent children should be developed. Society needs to become more enlightened about organ donation and transplantation patients.
