Assessing how consumers interpret and act on results from at-home COVID-19 self-test kits: a randomized clinical trial.
The US Food and Drug Administration (FDA) authorized SARS-CoV-2 rapid at-home self-test kits for individuals with and without symptoms. How appropriately users interpret and act on the results of at-home COVID-19 self-tests is unknown. The objective of this study was to assess how users of at-home COVID-19 self-test kits interpreted and acted on results when given instructions authorized by the FDA, instructions based on decision science principles, or no instructions.

Collaborative case review: a systems-based approach to patient safety event investigation and analysis.
The objectives of this study were to assess a system-based approach to event investigation and analysis--collaborative case reviews (CCRs)--and to measure impact of clinical specialty on strength of action items prescribed. The institutional review board-approved study describes the program, including a percentage of CCR from an institutional Electronic Safety Reporting System. Findings showed that an integrated multispecialty CCR co-led by the radiology department and an institutional patient safety program was associated with a higher proportion of CCR, stronger action items, and higher action item completion rate versus other hospital departments.

Dementia diagnosis in the hospital and outcomes among patients with advanced dementia documented in the Minimum Data Set.
This retrospective cohort study examined the association between a dementia diagnosis listed on a hospital claim and patient outcomes among individuals with a Minimum Data Set (MDS) assessment. The cohort was comprised of hospitalized patients aged 66 years and older with advanced dementia noted on an MDS assessment completed within 120 days prior to their first hospitalization in 2017. Among 120,989 patients with advanced dementia and a nursing home stay, 90.6% had a dementia diagnosis on their hospital claims. Documentation of a dementia diagnosis was associated with lower use of intensive care unit or coronary care unit, use of invasive mechanical ventilation, and 30-day mortality. These patients also had a shorter hospital length of stay.

Diagnostic error in pediatrics: a narrative review.
This narrative review focuses on the relative paucity of large, high-quality studies of diagnostic errors and what is known at present about the incident and epidemiology as well as the established research for identifying, evaluating, and reducing diagnostic errors. The authors propose several key research questions aimed at addressing persistent gaps in the pediatric diagnostic error literature. The authors state that additional research is needed to better establish the epidemiology of diagnostic errors in pediatrics, including identifying high-risk clinical scenarios, patient populations, and groups of diagnoses.

Differentiating multisystem inflammatory syndrome in children: a single-centre retrospective cohort study.
This study’s objective was to identify clinical and laboratory findings that distinguished multisystem inflammatory syndrome in children (MIS-C) from febrile illnesses in which MIS-C was considered but ultimately excluded, and to examine the diseases that most often mimicked MIS-C in a tertiary medical center. All children who were hospitalized at the author’s center with fever were evaluated for MIS-C and were compared for clinical signs and symptoms, SARS-CoV-2 status, and laboratory studies between those with and without MIS-C. The authors identified 50 confirmed MIS-C cases (MIS-C(+)) and 68 children evaluated for, but ultimately not diagnosed with, MIS-C (MIS-C(-)). Symptoms of conjunctivitis, abdominal pain, fatigue, hypoxaemia, tachypnoea and hypotension at presentation were significantly more common among MIS-C(+) patients, with MIS-C(+) and MIS-C(-) patients having similar elevations in C-reactive protein (CRP), but were differentiated by thrombocytopenia, lymphopenia, and elevated ferritin, neutrophil/lymphocyte ratio, BNP and troponin. Children hospitalized with MIS-C were older, more likely to present with conjunctivitis, oral mucosa changes, abdominal pain and hypotension, and had higher neutrophil/lymphocyte ratios and lower platelet counts.

Physician specialties involved in thyroid cancer diagnosis and treatment: implications for improving health care disparities.
The authors sought to characterize providers involved in diagnosing and treating thyroid cancer. Patients with differentiated thyroid cancer from the Georgia and Los Angeles County Surveillance, Epidemiology and End Results registries were surveyed. The authors found that, among thyroid cancer patients, 40.6% reported being informed of their diagnosis by their surgeon, 37.9% by their endocrinologist, and 13.5% by their primary care physician (PCP). The researchers concluded that PCPs were involved in thyroid cancer diagnosis and treatment, and their involvement was greater among older patients and patients of minority race/ethnicity.

Comparing mammographic density assessed by digital breast tomosynthesis or digital mammography: the Breast Cancer Surveillance Consortium.
This study’s purpose was to assess the consistency of Breast Imaging Reporting and Data System (BI-RADS) breast density reporting comparing digital breast tomosynthesis (DBT) with digital mammography (DM) and to evaluate density as a breast cancer risk factor when assessed using DM versus DBT. A secondary analysis of data from the Breast Cancer Surveillance Consortium was used from 342,149 women aged 40-79 years who underwent at least two screening mammography examinations less than 36 months apart. There were no significant differences in breast density assessment in pairs consisting of one DM and one DBT examination (57,516 of 74,729 [77%]), two DM examinations (238,678 of 301,743 [79%]), and two DBT examinations (20,763 of 26,854). Results were similar when pair analysis was restricted to readings by the same radiologist. The breast cancer hazard ratios (HRs) for breast density were similar for DM and DBT. The HRs for density acquired using DM and DBT, respectively, were 0.55 and 0.37 for almost entirely fat, 1.47 and 1.36 for heterogeneously dense, and 1.72 and 2.05 for extremely dense breasts.

Diagnosis documentation of critically ill children at admission to a PICU.
This study’s objective was to describe how pediatric critical care clinicians document patients' diagnoses at PICU admission. PICU admission notes for 96 unique patients were reviewed. Findings showed that most PICU admission notes documented a rationale for the primary diagnosis and expressed diagnostic uncertainty. Clinicians varied widely in how they organized diagnostic information, used contextual details to clarify the diagnosis, and expressed uncertainty. Recommendations included future work to determine how diagnosis narratives affect clinical decision-making, patient care, and outcomes.

Home blood pressure monitoring for hypertension diagnosis by current recommendations: a long way to go.
This analysis examined how historical use of home blood pressure monitoring (HBPM) aligns with current out-of-office BP monitoring recommendations for hypertensive US adults without a previous hypertension diagnosis and how HBPM use varies by patient characteristics. A cohort of 7185 adults aged 20 years or older without a diagnosis of hypertension or antihypertensive medication use and a high office BP (≥130/80 mm Hg) who participated in the National Health and Nutrition Examination Survey (NHANES) 2009 to 2014 cycle were included. Participants who answered as having self-initiated or physician recommended HBPM were categorized as having used or having been told to use HBPM. The authors estimate that 31.4 million US adults did not have diagnosed hypertension, were not taking antihypertensive medications, and had an office BP ≥130/80 mm Hg. Out of that population, 95.3% would have met criteria to undergo out-of-office BP monitoring by the American College of Cardiology/American Heart Association (ACC/AHA) guidelines. Only 3.6% (1.1 million) were told to use HBPM, and 15.7% had used HPBM. There were no differences in use by race/ethnicity, sex, health insurance status, or source of routine healthcare. The authors suggest the use of a telemonitoring system to improve ease of HBPM.

Physician risk perception and testing behaviors for children with fever.
This study sought to determine whether physician risk perception was associated with the decision to obtain blood or imaging tests among children who present to the emergency department with fever. A retrospective, cross-section study was conducted at the Boston Children’s Hospital emergency department. Children aged 6 months to 18 years who presented with a fever from May 2014 to April 2019 were included. The authors assessed risk perception using 3 scales: the Risk Tolerance Scale (RTS), Stress from Uncertainty Scale (SUS), and Malpractice Fear Scale (MFS). Across 55 pediatric emergency physicians, there was no association found between risk perception and blood/imaging testing in febrile children for any of those scales.

Usability barriers and facilitators of a human factors engineering-based clinical decision support technology for diagnosing pulmonary embolism.
The authors sought to identify and describe the usability barriers and facilitators of a human factors engineering (HFE)-based clinical decision support (CDS) prior to implementation in the emergency department. Through debrief interviews, they identified 271 occurrences of usability barriers and facilitators of the HFE-based CDS. They concluded that the systematic use of HFE principles in the design of CDS improves the usability of these technologies and recommended workflow integration in order to reduce usability barriers.

Endometrial sampling for preoperative diagnosis of uterine leiomyosarcoma.
This retrospective cohort study examined the effectiveness of endometrial sampling for preoperative detection of uterine leiomyosarcoma in women undergoing hysterectomy, identified factors associated with missed diagnosis, and compared the outcomes of patients who had a preoperative diagnosis with those patients who had a missed diagnosis. A total of 79 patients with uterine leiomyosarcoma were included in the study. Of those patients, 46 (58.2%) were diagnosed preoperatively and 33 postoperatively. The groups were similar in age, race/ethnicity, bleeding symptoms, and comorbidities. Women who had endometrial sampling performed with hysteroscopy had a higher likelihood of preoperative diagnosis. Patients with localized stage (vs distant stage) or tumor size >11 cm were less likely to be diagnosed preoperatively.

Plasma β-Hydroxybutyrate for the diagnosis of diabetic ketoacidosis in the emergency department.
Diabetic ketoacidosis (DKA) is a common emergency department presentation of both new-onset and established diabetes mellitus (DM). β-Hydroxybutyrate (BOHB) provides a direct measure of the pathophysiologic derangement in DKA as compared with the nonspecific measurements of blood pH and bicarbonate. The objective of this study was to characterize the relationship between BOHB and DKA. The investigators concluded that β-Hydroxybutyrate accurately predicted DKA in children and adolescents. More importantly, because plasma BOHB is the ideal biochemical marker of DKA, BOHB may provide a more optimal definition of DKA for management decisions and treatment targets.

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.

Patient and clinician experiences of uncertainty in the diagnostic process: current understanding and future directions,.
The purpose of this study was to provide a comprehensive overview of the current literature on diagnosis-related uncertainty in patients and clinicians. The researchers describe 1) where patients and clinicians encounter uncertainty within the diagnostic process, 2) how uncertainty affects the diagnostic process, 3) origins of uncertainty related to probability/risk, ambiguity, or complexity, and 4) strategies for managing uncertainty. The study found that every step in the diagnostic process involves uncertainty. The researchers’ recommendations of strategies for general management included: acknowledging uncertainty, obtaining more information from patients, creating diagnostic safety nets such as educating patients about observing red flags, utilizing worst/ best case scenario planning, and communicating diagnostic uncertainty to patients, families, and colleagues. The study also delineated possible strategies specific to various aspects of diagnostic uncertainty.

Systems engineering analysis of diagnostic referral closed-loop processes.
This systems engineering (SE) analysis of diagnostic referral closed-loop processes examines process logic, variation, reliability, and failures for completing diagnostic referrals originating in two primary care practices serving different demographics, using dermatology as an illustrating use case. Research has shown that there is a 65-73% failure rate in completing diagnostic referrals, which is a significant patient safety problem. An interdisciplinary team collaborated to understand processes of initiating and completing diagnostic referrals. Cross-functional process maps were developed through iterative group interviews with an urban community-based health center and a teaching practice within a large academic medical center. Results were used to conduct an engineering process analysis, assess variation between and within practices, and identify common failure modes and potential solutions.

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.

Changes in the agreement between the Minimum Data Set and hospital Medicare claims measures of dementia.
The objective of this study was to examine the agreement between a clinical Minimum Data Set measure of dementia and a diagnosis of dementia documented on a hospital claim across three points in time. A second objective was to examine the extent to which the agreement varied by age, sex, and race/ethnicity. Findings showed that hospital claims for patients aged 66–75 were less likely to be accurate than those for other age groups and suggests that physicians do not always look for signs of dementia in younger adults. Additionally, Asian patients were less likely to have a diagnosis of dementia documented during hospitalization, which could be related to language barriers between patients and clinicians.

Incidence, duration, and risk factors associated with missed opportunities to diagnose herpes simplex encephalitis: a population-based longitudinal study.
This retrospective cohort study determined the frequency and duration of diagnostic delays for herpes simplex encephalitis (HSE) that are associated with increased morbidity and mortality. Data from the IBM Marketscan Databases from 2001-2017 was used. The authors estimated the number of visits with HSE-related symptoms before diagnosis that would be expected to occur in the absence of delays and compared this estimate to the observed pattern of visits. Then a simulation-based approach was used to compute the number of visits representing a delay. They identified 2667 patients diagnosed with HSE and estimated 45.9% of patients experienced at least 1 missed opportunity, with 21.9% of patients having delays lasting >7 days. Risk factors for delays included being seen only in the emergency department, age 65 or older, or a history of sinusitis or schizophrenia.

Racial and ethnic disparities in the delayed diagnosis of appendicitis among children.
The objective of this 3-year multicenter retrospective cohort study of children was to determine if there are race/ethnicity differences in rates of appendiceal perforation, delayed diagnosis of appendicitis, and diagnostic imaging during prior visit(s). Delayed diagnosis was defined as having at least one emergency department (ED) visit within 7 days preceding the appendicitis diagnosis. Out of 7,298 patients diagnosed with appendicitis and documented race/ethnicity, 2,567 had appendiceal perforation. Non-Hispanic (NH) Black children had a higher likelihood of perforation (36.5% versus 34.9%) then non-Hispanic whites. They also were over twice as likely to have delayed diagnosis (4.7% versus 2.0%). Eighty-nine patients (43.2%) patients with delayed diagnosis had abdominal imaging during the prior visits. However, NH-Black children were less likely to have any imaging (28.2% versus 46.2%) or definitive imaging (10.3% versus 35.9%).

What happens after a positive primary care autism screen among historically underserved families? Predictors of evaluation and autism diagnosis.
This study examined predictors of receiving a recommended diagnostic evaluation after a recommended primary care-administered autism screen, and of those who screen positive, who is most likely to be diagnosed with autism. Participants were 309 predominantly low-income, racial/ethnic minority parents and their child aged 15-27 months who screened positive with the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F). Significant predictors of diagnostic evaluation included older parental age, being non-Hispanic and the child having private insurance, lower child communication functioning, or receiving Early Intervention services. Significant predictors of an autism diagnosis included being male, having lower child communication functioning, screening directly in the parent’s preferred language, White/non-Hispanic parent, and no parent history of mood disorder.
