Trends in health care use and spending for young children with neurologic impairment.
This retrospective study examined trends in health care use and spending for young children with neurologic impairment (NI) during their first 5 years of life. This study of 13,947 children with NI used data in the multistate IBM Medicaid MarketScan Database from 2009 to 2017. Inpatient service use decreased from 66.8% during the first year down to 5.8% during the fifth year. Emergency department (ED) use decreased more gradually from 67.8% during the first year to 44.4% during the fifth year. Per-member-per-year spending decreased from $83,352 during the first year down to $1944 in the fifth year.

Investigation of bias in an epilepsy machine learning algorithm trained on physician notes.
Racial disparities in the utilization of epilepsy surgery are well documented, but it is unknown whether a natural language processing (NLP) algorithm trained on physician notes would produce biased recommendations for epilepsy presurgical evaluations. To assess this, an NLP algorithm was trained to identify potential surgical candidates using 1097 notes from 175 epilepsy patients with a history of resective epilepsy surgery and 268 patients who achieved seizure freedom without surgery (total N = 443 patients).

High-intensity telemedicine reduces emergency department use by older adults with dementia in senior living communities.
Individuals with dementia have high rates of emergency department (ED) use for acute illnesses. In this study, the investigators evaluated the effect of a high-intensity telemedicine program that delivered care for acute illnesses on ED use rates for individuals with dementia residing in senior living communities (SLCs; independent and assisted living).

Longitudinal pattern of pain medication utilization in peripheral neuropathy patients.
The authors of this article investigated the pattern and utilization of neuropathic pain medications in peripheral neuropathy patients. They found that opioid initiation and transition to chronic opioid therapy were frequent in the studied population despite few patients receiving more than one guideline-recommended medication. They concluded that efforts are needed to decrease opioid utilization and to increase guideline-recommended medication use in order to improve current neuropathic pain treatment.

Claims data analyses unable to properly characterize the value of neurologists in epilepsy care.
The authors sought to determine the association of a neurologist visit with health care use and cost outcomes for patients with incident epilepsy using health care claims data for individuals insured by United Healthcare from 2001 to 2016. They found that patients with epilepsy who visited a neurologist had greater subsequent health care use, medical costs, and care escalation than controls. They conclude that their comparison using administrative claims was plausibly confounded by case disease severity, as suggested by higher non-epilepsy care costs, and that linking patient-centered outcomes to claims data may provide the clinical resolution to assess care value within a heterogeneous population.

Long-term reduction of health care costs and utilization after epilepsy surgery.
This study assessed long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. It found that the mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses.

Headaches and neuroimaging: high utilization and costs despite guidelines.
Little is known about recent headache neuroimaging utilization, associated expenditures, and temporal trends. Looking at 51.1 million outpatient headache visits over 4 years, this study found that neuroimaging is ordered during 12% of these visits, costs $1 billion annually, and is increasing over time.
