An operational framework to study diagnostic errors in emergency departments: findings from a consensus panel.
The purpose of this study was to create an operational definition and framework to study diagnostic error in the emergency department setting. A multidisciplinary panel defined diagnostic errors, modified the National Academies of Sciences, Engineering, and Medicine's diagnostic process framework, and underscored the importance of outcome feedback to emergency department providers to promote learning and improvement related to diagnosis.

Use of patient complaints to identify diagnosis-related safety concerns: a mixed-method evaluation.
This retrospective cohort study evaluated the use of patient complaint data to identify patient safety concerns related to diagnosis as an initial step to using this information to facilitate learning and improvement. Patient complaints submitted to the Geisinger healthcare system were reviewed with 2 cohorts from August to December 2017 (cohort 1) and January to June 2018 (cohort 2). The authors selected complaints more likely to be associated with diagnostic concerns in Geisinger’s existing complaint taxonomy. In cohort 1, 1865 complaint summaries were reviewed and 177 (9.5%) were identified as concerning. The review identified 39 diagnostic errors. In cohort 2, 2423 patient complaints were reviewed and 310 (12.8%) concerning reports were identified. A 10% sample contained give diagnostic errors. Most errors were categorized as “Clinical Care” issues.

Validation of an electronic trigger to measure missed diagnosis of stroke in emergency departments.
Diagnostic errors are major contributors to preventable patient harm. In this study, the investigators validated the use of an electronic health record (EHR)-based trigger (e-trigger) to measure missed opportunities in stroke diagnosis in emergency departments (EDs). The investigators concluded that a symptom-disease pair-based e-trigger identified missed diagnoses of stroke with a modest positive predictive value, underscoring the need for chart review validation procedures to identify diagnostic errors in large data sets.

Identifying trigger concepts to screen emergency department visits for diagnostic errors.
The diagnostic process is a vital component of safe and effective emergency department (ED) care. There are no standardized methods for identifying or reliably monitoring diagnostic errors in the ED, impeding efforts to enhance diagnostic safety. In this study, the investigators sought to identify trigger concepts to screen ED records for diagnostic errors and describe how they can be used as a measurement strategy to identify and reduce preventable diagnostic harm.

Analyzing diagnostic errors in the acute setting: a process-driven approach.
In this study the authors describe an approach for analyzing failures in diagnostic processes in a small, enriched cohort of general medicine patients who expired during hospitalization and experienced medical error. Their objective was to delineate a systematic strategy for identifying frequent and significant failures in the diagnostic process to inform strategies for preventing adverse events due to diagnostic error.

Diagnostic errors in pediatric critical care: a systematic review.
This study is a systematic review on the prevalence, impact, and contributing factors related to diagnostic errors in the PICU. A database search was done for literature up through December 2019. Using specific criteria, 396 abstracts were screened, and 17 studies were included. Fifteen of 17 studies had an observational research design. Autopsy studies showed a 10-23% rate of missed major diagnosis with 5-16% of the errors having a potential adverse impact on survival and would have changed care management. Retrospective record review studies reported varying rates of diagnostic error from 8% in a general PICU population to 12% among unexpected critical admissions. About a quarter of those patients were discussed at PICU morbidity and mortality conferences. Most misdiagnosed conditions were cardiovascular, infectious, congenital, or neurologic. System, cognitive, and both system and cognitive factors were associated with diagnostic error but there is limited information on the impact of misdiagnosis.

Applying machine learning across sites: external validation of a surgical site infection detection algorithm.
Surgical complications have tremendous consequences and costs. Complication detection is important for quality improvement, but traditional manual chart review is burdensome. Automated mechanisms are needed to make this more efficient. The purpose of the study was to understand the generalizability of a machine learning algorithm between sites; automated surgical site infection (SSI) detection algorithms developed at one center were tested at another distinct center.

Development of a rubric for assessing delayed diagnosis of appendicitis, diabetic ketoacidosis and sepsis.
This study’s objective was to create a guide for objectively grading the likelihood of delayed diagnosis of appendicitis, new-onset diabetic ketoacidosis (DKA), and sepsis. Case vignettes were constructed for each condition and then presented to expert Delphi panels for review. In each vignette, the patient had a previous emergency department visit within 7 days of the delayed diagnosis. The panels graded the likelihood of a delayed diagnosis on a five-point scale. Consensus was achieved within three Delphi rounds for all appendicitis and sepsis vignettes, and 77% of DKA vignettes. The authors created a case review guide from the consensus scores that will aid researchers and quality improvement specialists in objective case review to determine if delayed diagnosis had occurred for those three conditions.

Increasing physician reporting of diagnostic learning opportunities.
This study investigated methods to improve physician reporting of diagnostic errors at the pediatric division of a hospital. In that pediatric hospital medicine (PHM) division only 1 diagnostic-related safety event was reported in the preceding 4 years. The authors aimed to improve attending physician reporting of suspected diagnostic errors from 0 to 2 per 100 PHM patient admissions within 6 months. The improvement team used the Model for Improvement and used the term diagnostic learning opportunity (DLO) with clinicians as opposed to diagnostic error to lessen the stigma. They developed an electronic reporting form and encouraged its use through reminders, scheduled reflection time, and monthly progress reports. Over the course of 13 weeks, there was an increase from 0 to 1.6 per patient admission reports files. Most events (66%) were true diagnostic errors.

Testing strategies and predictors for evaluating immediate and delayed reactions to cephalosporins.
Although 1% to 2% of the general population carries a cephalosporin allergy label (CAL), there is a lack of validated testing strategies and predictors of true allergy. The objective of this study was to identify cross-reactivity patterns and predictors of skin test positive (STP) in geographically disparate patients with a CAL. The investigators found that cephalosporin cross-reactivity was based on shared R1 groupings. Increasing time since the original reaction and the presence of a PAL with unknown cephalosporin tolerance predicted a lower likelihood of cephalosporin STP.
