Diagnostic error may result in serious harm for more than 500,000 patients and contribute to an estimated 10% of all patient deaths. Understanding diagnostic accuracy is crucial for improving patient outcomes and ensuring effective healthcare delivery. IHQSE Faculty, Drs. Michelle Knees and Katie Raffel, along with colleagues from the University of Colorado Division of Hospital Medicine, recently published an AHRQ Issue Brief aimed at furthering efforts to enhance diagnostic accuracy. The brief reviews a substantial body of literature on the impact of cognitive load on diagnostic accuracy, identifies areas for future research, and provides recommendations for integrating existing knowledge into current practice.

The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is used to compare performance on patient experience metrics across hospitals, but its impact on patient outcomes as well as its utility as an incentive metric for providers remains unclear. In this article for the Hospitalist, members of the Society of Hospital Medicine Performance Reporting and Measurement Committee, including IHQSE faculty member Anunta Virapongse, MD, MPH discuss the pros and cons of using HCAHPS as a metric for measuring performance in hospitalist programs.

IHQSE faculty member, Dr. Katie Raffel, along with Dr. Katie Brooks and the UPSIDE research team, recently published findings from a multicenter retrospective cohort study evaluating the association between use of stigmatizing language and diagnostic error. The prevalence of stigmatizing language was higher among patients with diagnostic errors than those without. Use of this language was associated with delays in care at presentation and errors in communication with patients and caregivers. This raises the question of whether stigmatizing language may be indicative of clinician biases that interfere with data gathering, communication, and clinical reasoning.

Diagnostic errors (DE) are a critical but understudied cause of preventable patient harm. While much work has focused on examining the incidence and factors contributing to DEs in ambulatory and emergency room settings, fewer studies have examined the incidence of DEs in hospitals or how they contribute to adverse events during the hospital encounter. IHQSE Faculty, Dr. Katie Raffel, along with other experts on diagnostic error, led an AHRQ-funded study at 31 US hospitals aimed at defining the prevalence and underlying causes of DEs in patients who die in the hospital or are transferred to the ICU after the first 48 hours.
