Kaiser Permanente Researcher Profiles


 
Mai N. Nguyen-Huynh, MD MAS, is a board certified vascular neurologist. She is a research scientist at the Kaiser Permanente Northern California Division of Research. She is also the Director of Kaiser Primary Stroke Centers in the Diablo Service Area, and an assistant professor of neurology at the University of California San Francisco. Her research interests include stroke and transient ischemic attack epidemiology with a focus on acute management and outcomes of transient ischemic attack, large artery atherosclerotic disease and racial-ethnic variation in stroke risks and outcomes.

How Fast is Fast Enough? Assessing Door-to-Needle Times and Outcomes of Stroke Patients Receiving Acute Thrombolysis Therapy Under the Kaiser Permanente Northern California Stroke EXPRESS Program

With stroke treatment, there is a general belief that "time is brain." However, there has been no published data examining specifically the association between door-to-needle times for acute treatment with intravenous alteplase in stroke patients and 90-day outcomes. In 2016, the Kaiser Permanente Northern California Stroke EXPRESS program rolled out at all 21 primary stroke centers with significant improvement in door-to-needle times. This study has two major aims: 1) to determine if there is an association between door-to-needle times and mortality at discharge and at 90-day post-treatment in patients who receive acute thrombolysis treatment with intravenous alteplase at Kaiser Permanente Northern California, and 2) to determine if there is an association between door-to-needle times and 90-day favorable functional outcome (defined as mRS 0-2) in patients who receive acute thrombolysis treatment with intravenous alteplase at Kaiser Permanente Northern California.

Predicting Readmission After Stroke Study (PRESS)

Hospital readmissions are a tremendous burden on patients, their families, and the health care system. In 2008, the Centers for Medicare and Medicaid Services began publicly reporting hospital-level, risk-standardized, 30-day readmission and mortality rates for acute myocardial infarction and heart failure. Stroke survivors also have high risk of new illness, worsened known diseases, functional decline, and a high death rate. Readmission rates of 20 to 27 percent within one year have been reported. A systematic review of predictors of hospital readmission after stroke yielded no risk-standardized models for comparing hospital readmission performance or predicting readmission risk after stroke. This project aims to create a risk-adjusted predictive model for re-hospitalization after ischemic stroke using retrospectively and prospectively collected patient-level and hospital-level data, and to validate the model retrospectively and prospectively.

A Randomized, Double-Blind, Multinational Study to Prevent Major Vascular Events with Ticagrelor Compared to Aspirin in Patients with Acute Ischemic Stroke

The primary objective of the trial is to compare the effect of 90-day treatment with ticagrelor (180 mg [two 90 mg tablets] loading dose on Day 1 followed by 90 mg twice daily maintenance dose for the remainder of the study) vs acetylsalicylic acid (ASA)-aspirin (300 mg [three 100 mg tablets] loading dose on Day 1 followed by 100 mg once daily maintenance dose for the remainder of the study) for the prevention of major vascular events (composite of stroke, myocardial infarction, and death) in patients with acute ischemic stroke or transient ischemic attack.

Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial (CREST-2)

Carotid revascularization for primary prevention of stroke (CREST-2) is two independent multi-center, randomized controlled trials of carotid revascularization and intensive medical management versus medical management alone in patients with asymptomatic high-grade carotid stenosis. One trial will randomize patients in a 1-to-1 ratio to endarterectomy versus no endarterectomy, and another will randomize patients in a 1-to-1 ratio to carotid stenting with embolic protection versus no stenting. Medical management will be uniform for all randomized treatment groups and will be centrally directed. The purpose of this trial is to determine the best way to prevent strokes in people who have a high amount of blockage of their carotid artery but no stroke symptoms related to that blockage.

NINDS Stroke Trials Network Northern California Regional Coordinating Stroke Center

The primary goal of the NINDS Stroke Trials Network is to maximize efficiencies to develop, promote and conduct high-quality, multi-site clinical trials focused on key interventions in stroke prevention, treatment, and recovery with the objective to have a balanced portfolio between all three approaches. The aims of the Northern California Regional Coordinating Stroke Center are to: 1) Become a resource to any network PI to plan, initiate and complete a clinical trial in the neurosciences. This will be a joint effort between UCSF and selected medical centers within Kaiser Permanente; and 2) Provide training opportunities to medical students, residents, fellows and faculty within the network to plan and conduct clinical trials.
