Piloting the Use of Patient-Specific Cardiac Models as a Novel Tool to Facilitate Communication During Cinical Consultations.

This pilot study aimed to assess the impact of using patient-specific three-dimensional (3D) models of congenital heart disease (CHD) during consultations with adolescent patients. Adolescent CHD patients (n = 20, age 15-18 years, 15 male) were asked to complete two questionnaires during a cardiology transition clinic at a specialist centre. The first questionnaire was completed just before routine consultation with the cardiologist, the second just after the consultation. During the consultation, each patient was presented with a 3D full heart model realised from their medical imaging data. The model was used by the cardiologist to point to main features of the CHD. Outcome measures included rating of health status, confidence in explaining their condition to others, name and features of their CHD (as a surrogate for CHD knowledge), impact of CHD on their lifestyle, satisfaction with previous/current visits, positive/negative features of the 3D model, and open-ended feedback. Significant improvements were registered in confidence in explaining their condition to others (p = 0.008), knowledge of CHD (p < 0.001) and patients' satisfaction (p = 0.005). Descriptions of CHD and impact on lifestyle were more eloquent after seeing a 3D model. The majority of participants reported that models helped their understanding and improved their visit, with a non-negligible 30% of participants indicating that the model made them feel more anxious about their condition. Content analysis of open-ended feedback revealed an overall positive attitude of the participants toward 3D models. Clinical translation of 3D models of CHD for communication purposes warrants further exploration in larger studies.

Use of 3D models of congenital heart disease as an education tool for cardiac nurses.

BACKGROUND: Nurse education and training are key to providing congenital heart disease (CHD) patients with consistent high standards of care as well as enabling career progression. One approach for improving educational experience is the use of 3D patient-specific models. OBJECTIVES: To gather pilot data to assess the feasibility of using 3D models of CHD during a training course for cardiac nurses; to evaluate the potential of 3D models in this context, from the nurses' perspective; and to identify possible improvements to optimise their use for teaching. DESIGN: A cross-sectional survey. SETTING: A national training week for cardiac nurses. PARTICIPANTS: One hundred cardiac nurses (of which 65 pediatric and 35 adult). METHODS: Nurses were shown nine CHD models within the context of a specialized course, following a lecture on the process of making the models themselves, starting from medical imaging. Participants were asked about their general learning experience, if models were more/less informative than diagrams/drawings and lesion-specific/generic models, and their overall reaction to the models. Possible differences between adult and pediatric nurses were investigated. Written feedback was subjected to content analysis and quantitative data were analyzed using nonparametric statistics. RESULTS: Generally models were well liked and nurses considered them more informative than diagrams. Nurses found that 3D models helped in the appreciation of overall anatomy (86%), spatial orientation (70%), and anatomical complexity after treatment (66%). There was no statistically significant difference between adult and pediatric nurses' responses. Thematic analysis highlighted the need for further explanation, use of labels and use of colors to highlight the lesion of interest amongst improvements for optimizing 3D models for teaching/training purposes. CONCLUSION: 3D patient-specific models are useful tools for training adult and pediatric cardiac nurses and are particularly helpful for understanding CHD anatomy after repair.

Fortune favours the brave: composite first-person narrative of adolescents with congenital heart disease.

BACKGROUND: An interdisciplinary framework including a narrative element could allow addressing lack of awareness or excessive anxieties and teasing out divergences between patients' health status and their expectations. This could be particularly relevant for adolescents with congenital heart disease (CHD). OBJECTIVE: To develop a collective narrative ensuing from a creative activity involving adolescents with CHD, in order to explore their health perceptions and expectations. DESIGN: Artist-led workshop process supported by a multidisciplinary team. SETTING AND PARTICIPANTS: Young people with CHD (n=5, age 17-18 years, two men) were involved in the creative process, which encouraged them, over two sessions, to elaborate imagery relating to their uniqueness as individuals and their hearts. On top of creative activities (including self-portraits, embossing, body mapping and creative writing), participants were also shown their hearts in the form of cardiovascular MRIs and three-dimensional (3D) models manufactured by means of 3D printing. METHODS: A composite first-person narrative approach was adopted to handle the emerged phenomenological descriptions and creative outputs, in order to shape a unified story. RESULTS: The composite first-person narrative highlighted themes central to the patients, including their interpretation of medical references, their resilience and their awareness of anatomical complexity. DISCUSSION AND CONCLUSIONS: Exploring the narrative of adolescents with CHD can offer unique insight into the way they view their hearts at a crucial stage of their care. An artist-led creative workshop supported by a multidisciplinary team can be a valuable approach to collect such narratives from patients and begin exploring them.

3D-manufactured patient-specific models of congenital heart defects for communication in clinical practice: feasibility and acceptability.

OBJECTIVES: To assess the communication potential of three-dimensional (3D) patient-specific models of congenital heart defects and their acceptability in clinical practice for cardiology consultations. DESIGN: This was a questionnaire-based study in which participants were randomised into two groups: the 'model group' received a 3D model of the cardiac lesion(s) being discussed during their appointment, while the 'control group' had a routine visit. SETTING: Outpatient clinic, cardiology follow-up visits. PARTICIPANTS: 103 parents of children with congenital heart disease were recruited (parental age: 43±8 years; patient age: 12±6 years). In order to have a 3D model made, patients needed to have a recent cardiac MRI examination; this was the crucial inclusion criterion. INTERVENTIONS: Questionnaires were administered to the participants before and after the visits and an additional questionnaire was administered to the attending cardiologist. MAIN OUTCOME MEASURES: Rating (1-10) for the liking of the 3D model, its usefulness and the clarity of the explanation received were recorded, as well as rating (1-10) of the parental understanding and their engagement according to the cardiologist. Furthermore, parental knowledge was assessed by asking them to mark diagrams, tick keywords and provide free text answers. The duration of consultations was recorded and parent feedback collected. RESULTS: Parents and cardiologists both found the models to be very useful and helpful in engaging the parents in discussing congenital heart defects. Parental knowledge was not associated with their level of education (p=0.2) and did not improve following their visit. Consultations involving 3D models lasted on average 5 min longer (p=0.02). CONCLUSIONS: Patient-specific models can enhance engagement with parents and improve communication between cardiologists and parents, potentially impacting on parent and patient psychological adjustment following treatment. However, in the short-term, parental understanding of their child's condition did not improve.

Involving patients, families and medical staff in the evaluation of 3D printing models of congenital heart disease.

OBJECTIVE: To develop a participatory approach in the evaluation of 3D printed patient-specific models of congenital heart disease (CHD) with different stakeholders who would potentially benefit from the technology (patients, parents, clinicians and nurses). METHODS: Workshops, focus groups and teaching sessions were organised, targeting different stakeholders. Sessions involved displaying and discussing different 3D models of CHD. Model evaluation involved response counts from questionnaires and thematic analysis of audio-recorded discussions and written feedback. RESULTS: Stakeholders' responses indicated the scope and potential for clinical translation of 3D models. As tangible, three-dimensional artefacts, these can have a role in communicative processes. Their patient-specific quality is also important in relation to individual characteristics of CHD. Patients indicated that 3D models can help them visualise 'what's going on inside'. Parents agreed that models can spark curiosity in young people. Clinicians indicated that teaching might be the most relevant application. Nurses agreed that 3D models improved their learning experience during a CHD course. CONCLUSION: Engagement of different stakeholders to evaluate 3D printing technology for CHD identified the potential of the models for improving patient­ doctor communication, patient empowerment and training. PRACTICE IMPLICATIONS: A participatory approach could benefit the clinical evaluation and translation of 3D printing technology.
