Here’s a breakdown of the provided text, focusing on the key findings and implications of the studies discussed:
Overall Goal: The text discusses how telestroke networks aim to improve stroke care, notably for those in underserved or remote areas, and examines whether these networks effectively address disparities based on race, sex, and socioeconomic status.
What is Telestroke?
Telestroke aims to improve care for stroke patients who live far from “complete stroke centers.”
Complete stroke centers offer a full spectrum of neuroendovascular care, including thrombectomy.
Thrombectomy is a minimally invasive procedure to reopen blocked brain arteries, crucial for treating ischemic strokes. Telestroke allows patients in rural areas to receive virtual diagnoses and treatment processing at hospitals closer to them, extending the reach of specialized neurointerventional care.
This can help address geographic and racial disparities by bringing services closer to historically underserved communities.
Key Findings from the Studies:
Study 1: Sex Differences in acute Ischemic Stroke Outcomes in a Telestroke Network
Focus: Examined 7,947 patients with ischemic stroke in a telestroke network. Thrombectomy: Men and women were equally likely to receive thrombectomy.
TPA Administration: A slightly lower percentage of women (13%) received tissue plasminogen activator (TPA) compared to men (15%).TPA is a medication to break blood clots.
Hospital Stay & NIH Scores: Men and women spent similar times in the hospital and had comparable National Institutes of Health (NIH) stroke scale scores upon discharge.
Implication: While thrombectomy access was equitable, there was a slight difference in TPA administration by sex.
Study 2: ethnic Disparities in stroke Outcomes Attenuated by the Effectiveness of a Telestroke Network
Focus: Examined 2,952 white patients and 1,122 black patients with suspected ischemic stroke receiving telestroke care.
Acute Care: Telestroke networks appear to help reduce racial disparities in acute stroke care, specifically in TPA administration and mechanical thrombectomy. Immediate care was equitable between racial groups.
Post-AVC Rehabilitation: However, post-stroke rehabilitation outcomes differed between racial groups.
Implication: Telestroke is effective in improving acute care equity but doesn’t fully address long-term disparities in rehabilitation. Further research is needed on long-term disparities and rehabilitation access. Addressing socioeconomic barriers and improving post-AVC care access are crucial for true equity.
Study 3: The Effects of Neighborhood Disadvantage on stroke Network and Neurological Outcomes After Mechanical Thrombectomy
Focus: Examined patients who received thrombectomies at a large hospital, analyzing how socioeconomic status (SES) affected their treatment pathway and outcomes. Patient Pathways:
Ground Sorting: Half of the patients were assessed by EMS at the scene and immediately transported to a full stroke center for thrombectomy.
Transfer: The other half were sent to the nearest hospital and then transferred to a full stroke center.
Socioeconomic Status (SES) Measurement: Used the Area deprivation Index (ADI) to categorize SES.
Key Finding:
Patients of all SES levels who received immediate transport to the correct hospital (ground sorting) had better outcomes after thrombectomy then those who were transferred.
For patients who had to be transferred, those from more disadvantaged neighborhoods experienced longer waits for thrombectomy and had poorer health outcomes after the stroke.
Implication: The initial pathway of care (direct transport vs. transfer) significantly impacts outcomes, and socioeconomic disadvantage exacerbates negative outcomes for those who require transfers due to longer wait times.
Quote from Basel Musmar,MD:
“it is very encouraging to see that racial and sex arrangements can be perhaps mixed by p” (The quote is cut off,but the sentiment is positive regarding telestroke’s potential to mitigate racial and sex disparities).
In Summary:
The text highlights the promise of telestroke in improving stroke care access and equity. While telestroke appears to be effective in reducing acute disparities based on race and sex, it doesn’t fully solve long-term rehabilitation disparities. moreover,socioeconomic factors,particularly neighborhood disadvantage,can still lead to meaningful differences in treatment pathways and outcomes,especially when patients require transfers for specialized care. The research emphasizes the ongoing need to address socioeconomic barriers and improve post-stroke rehabilitation access to achieve truly equitable stroke care.
