The third edition of this important book continues to provide advanced practice nurses (APNs) with a framework for measuring the outcomes of their work. Regardless of the APN’s specialty, understanding the literature about APN outcomes and how to assess those outcomes is an essential skill. The first 5 chapters of this book reflect on measuring outcomes, analyzing economic outcomes, selecting outcome measures, the challenges of designing and implementing outcome assessments, and identifying specific instruments and measures for outcome assessment. The next 6 chapters offer outcome assessments and measures for various specialty types such as cardiovascular nursing, clinical nurse specialists, nurse anesthesia, and doctor of nursing practice. The final chapter offers an approach to furthering research on APN outcomes. Each chapter in the book begins with objectives and discussion questions and ends with references, additional reading suggestions, and resources.
