When Guideline-Concordant Standardized Care Results in Healthcare Disparities.

AbstractClinical red blood cell transfusion guidelines have been widely adopted in clinical practice, resulting in standardized transfusion practices in hospitalized patients with anemia. Standardization of transfusion practice has been welcomed by clinicians and health systems as a mechanism for reducing unnecessary, harmful, and costly practice variation that results in healthcare disparities. However, overzealously applied guidelines can have deleterious consequences for individual patients, ultimately resulting in and/or exacerbating healthcare disparities, rather than resolving them. This article provides empirical examples of the adverse consequences from the well-meaning attempt to standardize transfusion practice based on clinical practice guidelines and discusses the ethical implications of standardized transfusion practice.
