The COVID-19 pandemic threw the world into turmoil and exposed a cascade of vulnerabilities. One of the many lessons learned from this pandemic is that epidemiological principles must be applied to manage healthcare services and control disease in populations. Managerial Epidemiology: Cases and Concepts provides a comprehensive introduction to epidemiology and its use in healthcare management. Extensively revised, this edition demonstrates, through 64 real-world case studies and numerous examples, how the tools and principles of epidemiology can help managers make better-informed decisions. Updates include: two new chapters on population health and confounding, bias, and effect modification; new cases focused on relevant healthcare management issues, such as health risk factors and capitation rates; a completely rewritten chapter on epidemiology and financial management; heavily revised chapters on case-control studies, cohort studies, randomized clinical trials, infectious disease epidemiology, mortality and risk adjustment, and cost-effectiveness analysis; a sharper focus on healthcare-acquired infections; and greater emphasis on needs assessment and healthcare planning. The book's case studies are presented in three levels. In-chapter cases and answer guides form an integral component of the book's learning process. End-of-chapter cases provide additional exercises for practical application, with answers supplied at the back of the book so that students can self-quiz. In the book's final section, in-depth capstone cases offer an opportunity for reviewing and synthesizing material from specific chapters. Today more than ever, healthcare administrators must use the information provided by epidemiological methods to optimally manage interventions, treatments, and healthcare services that affect the health of populations.
