Weekend versus weekday asthma-related emergency department utilization.
The objective of this study was to assess variation in pediatric asthma-related emergency department (ED) visits between weekends and weekdays. Data was taken from California 2016 Medicaid data and Vermont 2016 and Massachusetts 2015 all-payer claims sources for children and adolescents in stratified groups aged 3 to 21. The asthma-related ED visit rate was slightly lower on weekends. The authors concluded that their findings suggest the increase of access options during the weekend may not necessarily decrease asthma-related ED visits.

Follow-up after asthma emergency department visits and its relationship with subsequent asthma-related utilization.
Researchers sought to assess the association between follow-up after an asthma-related emergency department (ED) visit and the likelihood of subsequent asthma-related ED utilization. Using data from California Medicaid, Vermont, and Massachusetts all-payer claims databases, they found a protective association between outpatient 14-day follow-up and asthma-related ED revisits. They suggested that this may reflect improved asthma control as providers follow the NHLBI guideline stepwise approach.

Automated pulmonary embolism risk assessment using the Wells criteria: validation study.
The authors sought to create an automated process to calculate the Wells score for pulmonary embolism for emergency department patients, which might reduce unnecessary computed tomography pulmonary angiography (CTPA) testing. They designed the process using electronic health records data elements, including free-text fields, and calculated Wells scores for a sample of adult emergency department visits that resulted in a CTPA study for pulmonary embolism at two tertiary care hospitals in New York. After validation, the authors concluded that the development of the automated process to classify risk for pulmonary embolism in emergency department visits was successful.
