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.

Modeling the impact of delaying the diagnosis of non-small cell lung cancer during COVID-19
The novel coronavirus (COVID-19) pandemic has led surgical societies to recommend delaying diagnosis and treatment of suspected lung cancer for lesions less than 2 cm. The COVID-19 infection rate at which immediate operative risk exceeds benefit is unknown. Delaying diagnosis can lead to disease progression, but the impact of this delay on mortality is unknown. In this study, the investigators sought to model immediate versus delayed surgical resection in a suspicious lung nodule less than 2 cm.

Risk factors for suboptimal bowel preparation for colonoscopy in pediatric patients.
Suboptimal bowel cleansing is common in children and can impact diagnostic and therapeutic outcomes. In this retrospective study, the investigators aimed to identify risk factors for suboptimal bowel preparation for colonoscopy in pediatric patients. The investigators concluded that Medicaid status and English as a second language were risk factors. They highlighted distinct associations from those reported in the adult literature including failure to thrive and younger age.

Height of fever and invasive bacterial infection.
This study evaluated the association of higher fevers with invasive bacterial infection (IBI) among febrile infants ≤60 days of age. Maximum temperatures of febrile infants with IBI were compared to infants without IBI. The median temperature was higher for infants with IBI (38.8°C) compared to those without IBI (38.4°C). Temperatures ranges of 39°C-39.4°C and 39.5°C-39.9°C were associated with a higher likelihood of IBI, although 30.4% of febrile infants with IBI had maximum temperatures <38.5°C.

Monitoring diagnostic safety risks in emergency departments: protocol for a machine learning study.
This study’s objective will be to identify variables associated with diagnostic errors in emergency departments using large-scale EHR data and machine learning techniques. It will use trigger algorithms with electronic health record (EHR) data repositories to generate a large data set of records that are labeled trigger-positive or trigger-negative, depending on if they meet certain criteria. This study will be conducted by 2 academic medical centers with affiliated community hospitals.

A machine learning model for identifying patients at risk for wild-type transthyretin amyloid cardiomyopathy.
Transthyretin amyloid cardiomyopathy, an often-unrecognized cause of heart failure, is now treatable with a transthyretin stabilizer. It is therefore important to identify at-risk patients who can undergo targeted testing for earlier diagnosis and treatment, prior to the development of irreversible heart failure. In this study, the investigators showed that a random forest machine learning model could identify potential wild-type transthyretin amyloid cardiomyopathy using medical claims data.

Incidence, duration and risk factors associated with delayed and missed diagnostic opportunities related to tuberculosis: a population-based longitudinal study.
Missed opportunities to diagnose tuberculosis are costly to patients and society. In this retrospective cohort study, the investigators (1) estimated the frequency and duration of diagnostic delays among patients with active pulmonary tuberculosis and (2) determined the risk factors for experiencing a diagnostic delay. The investigators found that many patients with tuberculosis experience multiple missed diagnostic opportunities prior to diagnosis.

Using voluntary reports from physicians to learn from diagnostic errors in emergency medicine.
The researchers analysed incidents reported by ED physicians to determine disease conditions, contributory factors and patient harm associated with ED-related diagnostic errors. Among the 209 incidents, they identified 214 diagnostic errors associated with 65 unique diseases/conditions. Most diagnostic errors in ED appeared to relate to common disease conditions.

Colorectal cancer outcomes and treatment patterns in patients too young for average-risk screening.
The researchers investigated the national treatment patterns and outcomes of patients younger than 50 with colorectal cancer (CRC). They found that patients with CRC diagnosed at age <50 years are more likely to present with advanced-stage disease. However, they receive more aggressive therapy and achieve longer disease-specific survival, despite the greater percentage of patients with advanced-stage disease.
