This innovative textbook teaches the basics of drug information, literature evaluation, and biostatistics, and relates these topics to evidence-based pharmaceutical care. Readers will learn what to look for in studies, how to critique them, and how to apply them in clinical pharmacy practice. A major focus is critical appraisal of evidence derived from different types of studies—cases, cohorts, surveys, randomized controlled clinical trials, pharmacoeconomic studies, and systematic reviews. Concluding chapters discuss clinical decision-making using evidence from studies.
