Care of People with Diabetes A Manual for Healthcare Practice

Now in its fifth edition, Care of People with Diabetes is a comprehensive clinical manual for nurses, healthcare professionals and students alike, providing an extensive summary of the most up-to-date knowledge in a rapidly developing field, as well as the role of education and self-care in achieving desirable outcomes. Covering both the theory and evidence-based practice of diabetes care, this authoritative volume integrates traditional thinking and innovative concepts to challenge readers to ‘think outside the box’ when rendering care.

• New and updated content on the pathophysiology of diabetes and the implications for management, how to apply guideline recommendations in practice, and contemporary evidence for best practice diabetes care
• Highlights personalised care and shared, evidence-based decision-making, emphasising the need for effective communication to reduce judgmental language and the negative effect it has on wellbeing and outcomes
• Written by internationally recognised experts in diabetes care, research and education
• Includes a range of learning features, such as practice questions, key learning points, diagrams, and further reading suggestions

Care of People with Diabetes is an essential companion to clinical practice for both trainee and experienced nurses and healthcare professionals, particularly those in acute care settings, and students undertaking diabetes courses or preparing for qualification exams.
