Highly acclaimed in its first three editions, McWhinney's Textbook of Family Medicine is one of the seminal texts in the field. While many family medicine texts simply cover the disorders a practitioner might see in clinical practice, McWhinney's defines the principles and practices of family medicine as a separate and distinct field of practice. The fourth edition presents six new clinical chapters of common problems in family medicine: respiratory illness, musculoskeletal pain, depression, diabetes, obesity and multimorbidity. This new edition also provides information on stewardship of resources, patient information and data, delivery of care in the home, and consultation and referral. The volume also covers continuing advances in the research base of family medicine. Readers will come away with a deeper appreciation for the role of the generalist in healthcare.
