Article Synopsis
  • Benzodiazepines are often prescribed to older patients after an acute ischemic stroke, despite guidelines advising against this for those aged 65 and over.
  • An analysis of Medicare claims from 2013 to 2021 showed that 4.9% of stroke survivors started benzodiazepine treatment, with higher initiation rates among females and in the southeastern US.
  • Although there was a slight decline in new prescriptions over the years, many patients received overly long prescriptions, indicating a need for better prescribing policies.

Background And Objectives: Visibility of sexual and gender minority (SGM) people has been steadily increasing over the recent years; however, little is known about the distinct seizure and mental health characteristics among SGM people with epilepsy. In this study, we describe these characteristics among SGM subgroups.

Methods: Data on demographics, seizure metrics, mental health, and quality of life were collected using patient-reported questionnaires gathered at first epilepsy clinic visits as part of routine clinical care from January 2019 to September 2023 at Massachusetts General Hospital.

Rationale: Despite guideline warnings, older acute ischemic stroke (AIS) survivors still receive benzodiazepines (BZD) for agitation, insomnia, and anxiety despite being linked to severe adverse effects, such as excessive somnolence and respiratory depression. Due to polypharmacy, drug metabolism, comorbidities, and complications during the sub-acute post-stroke period, older adults are more susceptible to these adverse effects. We examined the impact of receiving BZDs within 30 days post-discharge on survival among older Medicare beneficiaries after an AIS.

Fall-related injuries (FRIs) are a major cause of hospitalizations among older patients, but identifying them in unstructured clinical notes poses challenges for large-scale research. In this study, we developed and evaluated Natural Language Processing (NLP) models to address this issue. We utilized all available clinical notes from the Mass General Brigham for 2,100 older adults, identifying 154,949 paragraphs of interest through automatic scanning for FRI-related keywords.

Background And Objectives: Older adults receive benzodiazepines for agitation, anxiety, and insomnia after acute ischemic stroke (AIS). No trials have been conducted to determine if benzodiazepine use affects poststroke mortality in the elderly.

Methods: We examined the association between initiating benzodiazepines within 1 week after AIS and 30-day mortality.

Background: Older adults occasionally receive seizure prophylaxis in an acute ischemic stroke (AIS) setting, despite safety concerns. There are no trial data available about the net impact of early seizure prophylaxis on post-AIS survival.

Methods: Using a stroke registry (American Heart Association's Get With The Guidelines) individually linked to electronic health records, we examined the effect of initiating seizure prophylaxis (ie, epilepsy-specific antiseizure drugs) within 7 days of an AIS admission versus not initiating in patients ≥65 years admitted for a new, nonsevere AIS (National Institutes of Health Stroke Severity score ≤20) between 2014 and 2021 with no recorded use of epilepsy-specific antiseizure drugs in the previous 3 months.

Background: Each year, thousands of older adults develop delirium, a serious, preventable condition. At present, there is no well-validated method to identify patients with delirium when using Medicare claims data or other large datasets. We developed and assessed the performance of classification algorithms based on longitudinal Medicare administrative data that included International Classification of Diseases, 10th Edition diagnostic codes.

Article Synopsis
  • The Epilepsy Learning Healthcare System (ELHS) was established in 2018 to improve outcomes for epilepsy patients, but data fragmentation posed challenges for effective reporting and participation.
  • Researchers aimed to implement an open-source Data Integration (DI) method to connect clinical data from electronic health records (EHR) to the national ELHS registry.
  • The feasibility study collected data from 1806 epilepsy patients, focusing on key metrics like seizure type and frequency, and successfully automated the data extraction and preprocessing, making it readily accessible for ongoing quality improvement efforts.

Routine outpatient epilepsy care has shifted from in-person to telemedicine visits in response to safety concerns posed by the coronavirus disease 2019 (COVID-19) pandemic. But whether telemedicine can support and maintain standardized documentation of high-quality epilepsy care remains unknown. In response, the authors conducted a quality improvement study at a level 4 epilepsy center between January 20, 2019, and May 31, 2020.

Objective: To describe the organization of the Epilepsy Learning Healthcare System (ELHS), a network that aims to improve care outcomes for people with epilepsy (PWE).

Materials And Methods: Patients and family partners, providers, researchers, epidemiologists, and other leaders collaborated to recruit epilepsy centers and community services organizations into a novel learning network. A multidisciplinary Coordinating Committee developed ELHS governance and organizational structure, including four key planning Cores (Community, Clinical, Quality Improvement, and Data).

This report is the outcome of the meeting "Environmental and Human Health Consequences of Arsenic" held at the MDI Biological Laboratory in Salisbury Cove, Maine, August 13-15, 2014. Human exposure to arsenic represents a significant health problem worldwide that requires immediate attention according to the World Health Organization (WHO). One billion people are exposed to arsenic in food, and more than 200 million people ingest arsenic via drinking water at concentrations greater than international standards.
