This 3rd edition of Evaluation Methods in Biomedical and Health Informatics has been extensively revised and expanded. It builds on a solid foundation of evaluation theory to explain methods and techniques within health informatics, using many examples, real-world case studies and numerous self-tests with answers. Expanded to 20 rather than 12 chapters, new chapters have been added on qualitative methods, ethics, mixed methods, evidence-based informatics and how to conduct evaluation studies using routine, real-world data.  Designed as a practical guide for masters and PhD students, informatics researchers and seasoned professionals seeking a comprehensive resource, this book describes health and biomedical information resource evaluation in a practical stepwise manner. Critiques and discussion of actual evaluation studies help to build the reader s knowledge of the judicious application of the techniques described.
