Hodges' model: the Sustainable Development Goals and public health - universal health coverage demands a universal framework.

Background to issue: Future sustainable healthcare delivery and systems need reflective practitioners and critical thinkers to engage the public to achieve health policy aims and objectives. Therefore, this descriptive review introduces a generic conceptual framework, adopting a specific theme to illustrate and demonstrate a model of care or any other context. Whatever the purpose, context or philosophical stance in healthcare and health literacy, there is no standardised generic conceptual framework to structure reflection and critical thinking. This work presents a pragmatic solution focused on the one-to-one relationship of learner-mentor, patient-clinician, public health professional-public and groups. Methods: The method is constructivist, an educational exercise, practical and the target group can be defined/viewed as student, teacher, patient, carer or member of the public in a health promotion campaign, for example. The building blocks are health and care concepts that arise clinically in practice, or for a student writing an assignment. As will be explained, concepts (including the Sustainable Development Goals) are assigned by the subject(s)-in this instance the authors-to a domain of knowledge. Results: As two-by-two tables, the results represent the structure of the conceptual framework, framing the content in a series of four knowledge (care) domains. The contents, ultimately the Sustainable Development Goals, may then be linked and relationships discussed. Results are produced gradually, building a cognitive or mind-map. The results, it must be stressed, are therefore qualitative. Conclusion: Drawing on educational theory and practice, the results are explored and justified using the theme of nutrition, and the often stated desirability in education of reflective practice and critical thinking abilities. Providing a series of cross-disciplinary, the reader will gain insight into the potential of Hodges' model to facilitate integrated, person-centred and care that improves parity of esteem, supporting students and qualified personnel in their learning careers.
