This new edition focuses on bias in health care and provides a variety of case examples related to the timely topics of unconscious bias and microaggressions encountered by patients, students, attending and resident physicians, nurses, staff, and advanced practice providers in various healthcare settings. The proliferation of literature on unconscious bias and microaggressions has raised public awareness around these concerns. This case compendium discusses strategies and addresses professional responses to bias in health care and extends beyond the individual patient and healthcare provider into the communities where biased assumptions and attitudes exist. Recognizing that ethnic minorities, the elderly, the poor, and persons with Medicaid coverage utilize the emergency department at higher rates than the general population, this compendium also builds upon the case studies from the first edition to cover a broader array of underserved minority groups.
