AI Article Synopsis
- The study aimed to analyze whether health information exchange (HIE) among hospitals leads to reduced visits to emergency departments (EDs) for patients with multiple encounters.
- Researchers combined Medicare claims data and hospital participation information to classify patient encounters and assess outcomes like repeat imaging and hospital admissions.
- While patients returning to the same hospital showed lower utilization rates, HIE did not consistently correlate with reduced repeat imaging; it did reduce hospital admissions after treat-and-release visits but increased admissions after discharges.
Article Abstract
Objective: To use more precise measures of which hospitals are electronically connected to determine whether health information exchange (HIE) is associated with lower emergency department (ED)-related utilization.
Materials And Methods: We combined 2018 Medicare fee-for-service claims to identify beneficiaries with 2 ED encounters within 30 days, and Definitive Healthcare and AHA IT Supplement data to identify hospital participation in HIE networks (HIOs and EHR vendor networks). We determined whether the 2 encounters for the same beneficiary occurred at: the same organization, different organizations connected by HIE, or different organizations not connected by HIE. Outcomes were: (1) whether any repeat imaging occurred during the second ED visit; (2) for beneficiaries with a treat-and-release ED visit followed by a second ED visit, whether they were admitted to the hospital after the second visit; (3) for beneficiaries discharged from the hospital followed by an ED visit, whether they were admitted to the hospital.
Results: In adjusted mixed effects models, for all outcomes, beneficiaries returning to the same organization had significantly lower utilization compared to those going to different organizations. Comparing only those going to different organizations, HIE was not associated with lower levels of repeat imaging. HIE was associated with lower likelihood of hospital admission following a treat-and-release ED visit (1.83 percentage points [-3.44 to -0.21]) but higher likelihood of admission following hospital discharge (2.78 percentage points [0.48-5.08]).
Discussion: Lower utilization for beneficiaries returning to the same organization could reflect better access to information or other factors such as aligned incentives.
Conclusion: HIE is not consistently associated with utilization outcomes reflecting more coordinated care in the ED setting.

Background: Hypoxic-ischemic encephalopathy (HIE) is still associated with death and sequelae including cerebral palsy and intellectual disability despite induced hypothermia. Biomarkers, as early predictive indicators of adverse outcomes, are lacking.
Aims: To investigate whether post-rewarming cerebrospinal fluid (CSF)-neuro-specific enolase (NSE) levels after hypothermia are associated with neurodevelopmental outcomes at age six years, alone or when combined with amplitude-integrated electroencephalography (aEEG) and brain magnetic resonance imaging (MRI), as neuroimaging and neurophysiological indicators, respectively.

Background: Vasoactive inotrope score, renal score, fibrosis-5 index, and lactate-albumin ratio have not been investigated before in determining multiple organ dysfunctions accompanying infants with hypoxic-ischemic encephalopathy (HIE) in neonatal intensive care units (NICUs). The aim of this study was to determine whether multiple organ dysfunctions that may accompany HIE in infants are correlated with vasoactive inotrope score (VIS), renal score (RS), fibrosis-5 index (FIB-5), and lactate-albumin ratio (LAR), and whether these parameters can predict morbidity and mortality.
Methods: This is a retrospective study, and 106 newborns diagnosed with HIE and treated with hypothermia were included in the study.

Background: Neonatal hypoxic-ischemic encephalopathy (HIE) has a high incidence and mortality rate, representing a significant patient burden. Therefore, treatment strategies that work synergistically with hypothermic therapies are urgently required. Punicalagin (PUN) is a natural and safe polyphenol with anti-inflammatory functions whose excellent water solubility and safety make it an advantageous perinatal medication.

Introduction: This study aimed to investigate the associations among seizures, clinical characteristics, and brain injury on Magnetic Resonance Imaging (MRI) in infants with Hypoxic Ischemic Encephalopathy (HIE), and to determine whether these findings can predict unfavorable neurodevelopmental outcomes.
Method: Clinical and electrographic seizures were assessed by amplitude-integrated electroencephalogram, and the extent of brain injury was evaluated by using MRI. At 12‒24 months of age, developmental impairment or death was assessed.
