Segmentation of Both Diseased and Healthy Skin From Clinical Photographs in a Primary Care Setting.

This work presents the first segmentation study of both diseased and healthy skin in standard camera photographs from a clinical environment. Challenges arise from varied lighting conditions, skin types, backgrounds, and pathological states. For study, 400 clinical photographs (with skin segmentation masks) representing various pathological states of skin are retrospectively collected from a primary care network. 100 images are used for training and fine-tuning, and 300 are used for evaluation. This distribution between training and test partitions is chosen to reflect the difficulty in amassing large quantities of labeled data in this domain. A deep learning approach is used, and 3 public segmentation datasets of healthy skin are collected to study the potential benefits of pretraining. Two variants of U-Net are evaluated: U-Net and Dense Residual U-Net. We find that Dense Residual U-Nets have a 7.8% improvement in Jaccard, compared to classical U-Net architectures (0.55 vs. 0.51 Jaccard), for direct transfer, where fine-tuning data is not utilized. However, U-Net outperforms Dense Residual U-Net for both direct training (0.83 vs. 0.80) and fine-tuning (0.89 vs. 0.88). The stark performance improvement with fine-tuning compared to direct transfer and direct training emphasizes both the need for adequate representative data of diseased skin, and the utility of other publicly available data sources for this task.

Education for Professional Chaplains: Should Certification Competencies Shape Curriculum?

The growing importance of professional chaplains in patient-centered care has raised questions about education for professional chaplaincy. One recommendation is that the curricula of Clinical Pastoral Education (CPE) residency programs make use of the chaplaincy certification competencies. To determine the adoption of this recommendation, we surveyed CPE supervisors from 26 recently re-accredited, stipended CPE residency programs. We found the curricula of 38% of these programs had substantive engagement with the certification competencies, 38% only introduced students to the competences, and 23% of the programs made no mention of them. The majority of the supervisors (59%) felt engagement with the competencies should be required while 15% were opposed to such a requirement. Greater engagement with chaplaincy certification competencies is one of several approaches to improvements in chaplaincy education that should be considered to ensure that chaplains have the training needed to function effectively in a complex and changing healthcare environment.

Workings of the human spirit in palliative care situations: a consensus model from the Chaplaincy Research Consortium.

BACKGROUND: Chaplaincy is a relatively new discipline in medicine that provides for care of the human spirit in healthcare contexts for people of all worldviews. Studies indicate wide appreciation for its importance, yet empirical research is limited. Our purpose is to create a model of human spiritual processes and needs in palliative care situations so that researchers can locate their hypotheses in a common model which will evolve with relevant findings. METHODS: The Model Building Subgroup worked with the Chaplaincy Research Consortium as part of a larger Templeton Foundation funded project to enhance research in the area. It met with members for an hour on three successive occasions over three years and exchanged drafts for open comment between meetings. All members of the Subgroup agreed on the final draft. RESULTS: The model uses modestly adapted existing definitions and models. It describes the human experience of spirituality during serious illness in three renditions: visual, mathematical, and verbal so that researchers can use whichever is applicable. The visual rendition has four domains: spiritual, psychological, physical and social with process arrows and permeable boundaries between all areas. The mathematical rendition has the same four factors and is rendered as an integral equation, corresponding to an integrative function postulated for the human spirit. In both renditions, the model is notable in its allowance for direct spiritual experience and a domain or factor in its own right, not only experience that is created through the others. The model does not describe anything beyond the human experience. The verbal rendition builds on existing work to describe the processes of the human spirit, relating it to the four domains or factors. CONCLUSIONS: A consensus model of the human spirit to generate hypotheses and evolve based on data has been delineated. Implications of the model for how the human spirit functions and how the chaplain can care for the patient or family caregiver's spiritual coping and well-being are discussed. The next step is to generate researchable hypotheses, results of research from which will give insight into the human spirit and guidance to chaplains caring for it.

Transcending differences to study the transcendent: an exploratory study of researchers' and chaplains' reflections on interdisciplinary spiritual care research collaboration.

BACKGROUND: Despite recognition of the centrality of professional board-certified chaplains (BCC) in palliative care, the discipline has little research to guide its practices. To help address this limitation, HealthCare Chaplaincy Network funded six proposals in which BCCs worked collaboratively with established researchers. Recognizing the importance of interdisciplinary collaboration in the development of a new field, this paper reports on an exploratory study of project members' reflections over time on the benefits and challenges of conducting inter-disciplinary spiritual care research. METHODS: Data collection occurred in two stages. Stage 1 entailed two independent, self-reflective focus groups, organized by professional discipline, mid-way through the site projects. Stage 2 entailed end-of-project site reports and a conference questionnaire. RESULTS: Eighteen professionals participated in the group discussions. Stage 1: researchers perceived chaplains as eager workers passionately committed to their patients and to research, and identified challenges faced by chaplains in learning to conduct research. Chaplains perceived researchers as passionate about their work, were concerned research might uncover negative findings for their profession, and sensed they used a dissimilar paradigm from their research colleagues regarding the 'ways of relating' to knowledge and understanding. Stage 2: researchers and chaplains noted important changes they ascribed to the interdisciplinary collaboration that were classified into six domains of cultural and philosophical understanding: respect; learning; discovery; creativity; fruitful partnerships; and learning needs. CONCLUSIONS: Chaplains and researchers initially expressed divergent perspectives on the research collaborations. During the projects' lifespans, these differences were acknowledged and addressed. Mutual appreciation for each discipline's strengths and contributions to inter-professional dialogue emerged.

What do I do? Developing a taxonomy of chaplaincy activities and interventions for spiritual care in intensive care unit palliative care.

BACKGROUND: Chaplains are increasingly seen as key members of interdisciplinary palliative care teams, yet the specific interventions and hoped for outcomes of their work are poorly understood. This project served to develop a standard terminology inventory for the chaplaincy field, to be called the chaplaincy taxonomy. METHODS: The research team used a mixed methods approach to generate, evaluate and validate items for the taxonomy. We conducted a literature review, retrospective chart review, focus groups, self-observation, experience sampling, concept mapping, and reliability testing. Chaplaincy activities focused primarily on palliative care in an intensive care unit setting in order to capture a broad cross section of chaplaincy activities. RESULTS: Literature and chart review resulted in 438 taxonomy items for testing. Chaplain focus groups generated an additional 100 items and removed 421 items as duplications. Self-Observation, Experience Sampling and Concept Mapping provided validity that the taxonomy items were actual activities that chaplains perform in their spiritual care. Inter-rater reliability for chaplains to identify taxonomy items from vignettes was 0.903. CONCLUSIONS: The 100 item chaplaincy taxonomy provides a strong foundation for a normative inventory of chaplaincy activities and outcomes. A deliberative process is proposed to further expand and refine the taxonomy to create a standard terminological inventory for the field of chaplaincy. A standard terminology could improve the ways inter-disciplinary palliative care teams communicate about chaplaincy activities and outcomes.
