What is Harrison’s Self-Assessment and Board Review, 20th Edition?
Harrison’s Self-Assessment and Board Review, 20th Edition, is an internal medicine question-and-answer review book containing more than 1,000 clinical questions with detailed explanations. Designed for students, house staff, and practitioners, it covers the major areas of internal medicine and supports board, shelf, and Step exam preparation.
Introduction
For learners of internal medicine, mastering a large body of clinical knowledge requires more than reading long chapters. Active recall, clinical problem-solving, and repeated exposure to patient-based questions are essential parts of effective study. Harrison’s Self-Assessment and Board Review, 20th Edition, is designed around this question-and-answer approach.
The book is a companion to the 20th edition of Harrison’s Principles of Internal Medicine and presents more than 1,000 questions with comprehensive explanations. Its questions are frequently structured as realistic clinical scenarios and may incorporate radiographic or pathologic images.
The stated purpose is to support students, house staff, and practicing clinicians through active learning and discussion.
The scope is broad because the book addresses the major areas of internal medicine rather than concentrating on a single subspecialty.
Its sections range from cardinal manifestations of disease and oncology to infectious diseases, cardiovascular medicine, respiratory and critical care disorders, renal disease, gastrointestinal disorders, rheumatology and immunology, endocrinology and metabolism, and neurology.
This makes the book particularly relevant to medical students, interns, residents, young physicians, and other healthcare professionals seeking a structured way to test and reinforce their internal medicine knowledge.

WHAT THIS BOOK COVERS
1. Cardinal Manifestations of Disease
The opening section focuses on the clinical manifestations that physicians encounter across multiple diseases and specialties. The questions address subjects such as prevention, screening, evidence-based medicine, pain, palliative care, headache, back pain, fever, syncope, dizziness, and other common clinical problems.
This organization is valuable because it encourages the learner to approach medicine from the patient's presenting problem rather than simply from a disease name. The early questions, for example, explore preventive strategies, screening principles, health-system errors, decision-making capacity, palliative care, pain management, and common clinical presentations.
The answer explanations then expand on the reasoning behind the selected answer. In one example involving dysphagia, the explanation distinguishes oral or pharyngeal dysphagia from esophageal dysphagia and discusses appropriate diagnostic approaches.
2. Oncology and Hematology
The oncology and hematology section forms one of the major specialty areas in the book. Its placement early in the volume reflects the broad internal medicine scope of the review.
The book's approach is not simply to list diseases. Questions are framed around clinical presentations and require readers to interpret information, establish differentials, and identify appropriate diagnostic or therapeutic concepts.
3. Infectious Diseases
The infectious diseases section covers a wide range of bacterial, viral, fungal, and other infectious conditions.
Examples include meningitis, endocarditis, Bartonella infection, gastrointestinal infections, respiratory viruses, HIV-related conditions, and vaccine-preventable infections. The questions frequently combine epidemiology, clinical presentation, diagnostic testing, microbiology, and treatment considerations.
The answer section can provide considerably more context than the question itself. For example, explanations discuss diagnostic reasoning and the clinical interpretation of tests such as the H. pylori urea breath test.
4. Cardiovascular Disorders
Cardiovascular medicine is covered in a dedicated section. The material includes clinical scenarios involving arrhythmias, syncope, coronary disease, and other cardiovascular problems.
The question format is especially useful for cardiovascular medicine because many conditions require interpretation of clinical findings, electrocardiographic patterns, imaging, and management choices. Examples in the book include questions involving atrial flutter, pre-excitation, ventricular arrhythmias, and cardiac arrest rhythms.
5. Respiratory System and Critical Care Illness
Respiratory medicine and critical care are combined in their own major section. The book uses clinical scenarios to test recognition, diagnosis, and management of pulmonary and critical illness presentations.
6. Kidney and Urinary Tract Disorders
The renal section addresses disorders of the kidney and urinary tract, maintaining the same board-style question-and-explanation format used throughout the volume.
7. Gastrointestinal Disorders
Gastroenterology is another major section. The questions address gastrointestinal presentations and related diagnostic and therapeutic issues.
The explanations demonstrate the book's emphasis on reasoning. For example, a discussion of dysphagia distinguishes the appropriate investigation according to whether the suspected problem is oropharyngeal or esophageal.
8. Rheumatology and Immunology
The rheumatology and immunology section includes clinical manifestations, diagnostic reasoning, autoimmune disease, inflammatory disorders, and related therapeutic concepts. The book also uses pathology and clinical images where appropriate; an example includes multiple clinical and microscopic images related to inflammatory myopathy.
9. Endocrinology and Metabolism
Endocrinology and metabolism occupy a dedicated section. Topics include diabetes, metabolic disorders, endocrine tumors, mineral and bone disorders, and other endocrine problems.
The questions are designed to test recognition of clinical patterns as well as underlying physiology and treatment principles. For example, the endocrine questions include scenarios involving pheochromocytoma and its diagnostic and management considerations.
10. Neurologic Disorders
Neurology is the final major section listed in the table of contents. It completes the book's broad coverage of internal medicine specialties.

Who Should Read This Book?
Medical Students
Medical students can use the book to transform passive reading into active recall. The clinical vignette format also provides practice in applying foundational knowledge to patient presentations.
Residents and House Staff
Residents are among the explicitly identified target readers. The broad internal medicine coverage makes the book suitable for structured revision across multiple organ systems while reinforcing clinical reasoning. The preface specifically describes the book as intended for students, house staff, and practitioners.
Specialists
Internal medicine specialists and subspecialty trainees may find the question format useful for identifying gaps in knowledge outside their primary area of practice. However, the book should be viewed as a review resource rather than a substitute for detailed specialty references.
Nurses
The book can provide useful exposure to internal medicine concepts for nurses seeking to strengthen their understanding of disease processes and clinical presentations. Nevertheless, it is principally structured around physician-oriented internal medicine assessment.
Pharmacists
Pharmacists working with medical teams may benefit from the clinical context surrounding therapeutics, diagnosis, and disease mechanisms. The extent of usefulness will depend on the reader's specific educational objectives.
Researchers and Medical Educators
Researchers and educators may find the clinical question-and-answer format useful for teaching, discussion, and identifying areas where learners need additional study. The preface specifically notes that the questions and answers are conducive to collaboration and discussion with colleagues.
Exam Candidates
This is one of the clearest use cases identified by the book itself. Its stated applications include board, shelf, and step examinations, along with repeated self-directed learning.
Why This Book is Useful
Clinical Relevance
The strongest feature of the book is its emphasis on clinical scenarios rather than isolated facts. Questions commonly begin with a patient presentation and ask the reader to determine the diagnosis, next step, mechanism, risk factor, investigation, or treatment.
That format mirrors the type of reasoning required when applying medical knowledge to real patients.
Evidence-Based Content
Evidence-based medicine itself is represented among the topics tested in the book. The first section includes questions on evidence-based medicine, screening, prevention, and clinical decision-making.
The book also emphasizes that medical knowledge changes. Its notice advises readers to confirm medical information with other sources, particularly for drug information and recommendations that may change over time.
Practical Application
The question-and-answer structure allows readers to immediately test whether they can apply a concept. Instead of simply recognizing a definition, the learner must process the information presented in a clinical vignette.
Board Examination Preparation
The book explicitly describes itself as a board and shelf examination preparation resource, and its promotional material states that its content is consistent with the internal medicine board examination blueprint.
Learning Efficiency
The format supports short, repeatable study sessions. Learners can work through a group of questions, review the explanations, identify weak areas, and return to those topics later.
The preface also describes additional delivery formats, including an adaptive-learning app intended to help users focus on areas of greatest need, along with eBook and AccessMedicine availability at the time of publication.
Table of Contents Overview
The book is divided into 10 major sections:
- Cardinal Manifestations of Disease — Questions and Answers
- Oncology and Hematology — Questions and Answers
- Infectious Diseases — Questions and Answers
- Disorders of the Cardiovascular System — Questions and Answers
- Disorders of the Respiratory System and Critical Care Illness — Questions and Answers
- Disorders of the Kidney and Urinary Tract — Questions and Answers
- Disorders of the Gastrointestinal System — Questions and Answers

Each section follows the central question-and-answer philosophy of the book, allowing learners to work through questions before consulting the explanatory material.
Strengths of The Book
The principal academic strength of Harrison’s Self-Assessment and Board Review 20th Edition is the combination of breadth and active learning.
First, the book covers essentially the full spectrum of internal medicine represented by its 10 major sections.
Second, the questions are not limited to simple factual recall. Clinical vignettes, radiographs, pathology images, and other visual material require learners to interpret information in context.
Third, the explanations are an important component of the educational design. The book specifically emphasizes explanations of both correct and incorrect choices, making the questions useful for learning rather than simply scoring.
Fourth, the fifth-edition preface reports that more than 60% of questions were replaced from the previous edition. This means the 20th-edition review is not simply a superficial revision of the earlier question bank.
Finally, the book's connection to Harrison’s Principles of Internal Medicine gives readers a clear framework for expanding their study when an explanation requires greater depth.
Limitations
The book's principal limitation is also inherent in its purpose: it is a self-assessment and review resource rather than a comprehensive replacement for a major internal medicine textbook.
The book provides explanations, but readers who need extensive background discussion may need to consult the associated Harrison’s Principles of Internal Medicine or other detailed references.
Another consideration is that medical knowledge changes. The book itself explicitly cautions readers that medicine is continually evolving and recommends confirming information with other references, particularly medication information and recommendations that may change after publication.
Comparison With Similar Books
The book occupies a particular niche among internal medicine study resources. Its defining characteristic is its integration with the 20th edition of Harrison’s Principles of Internal Medicine and its emphasis on clinical question-and-answer learning.
Compared with a conventional comprehensive textbook, it is more focused on active recall and self-assessment. Compared with a narrowly focused question bank, it offers unusually broad internal medicine coverage across multiple major specialties.
