US Acute Care Solutions and the University of Pennsylvania Work Together to Prevent Stroke Misdiagnosis

Press Release
Jan 7, 2025
CANTON, Ohio, January 7, 2025 — US Acute Care Solutions (USACS) is proud to announce a collaboration with the University of Pennsylvania Health System (Penn Medicine) to incorporate the USACS “dizziNIHSS” initiative at Penn Medicine’s three Philadelphia emergency departments, the Hospital of the University of Pennsylvania, Pennsylvania Hospital, and Penn Presbyterian Medical Center.
Designed to enhance diagnosis of posterior strokes, this innovative approach reminds clinicians to perform the NIH Stroke Scale (NIHSS), test of skew, and gait evaluation for any patient presenting with dizziness, vertigo, or imbalance. The new collaboration aims to transform stroke diagnosis and care, ultimately leading to better patient outcomes and population health.
The Stakes: Posterior Strokes and Catastrophic Outcomes
Posterior strokes are missed in as many as two-thirds of cases because many do not present with commonly recognized stroke symptoms like weakness, numbness, or speech difficulties. Instead, posterior strokes can be misdiagnosed as vertigo caused by inner ear dysfunction, fainting episodes, or even psychiatric diseases. The adage, “time is brain,” means that not identifying and treating strokes early can lead to catastrophic outcomes for patients. The dizziNIHSS approach prioritizes the NIHSS as a key diagnostic tool to identify strokes that are most commonly missed.
Why the NIHSS?
- NIHSS is superior to CT and MRI for detecting early strokes.
- The assessment can be performed immediately on any patient, by any clinician, at any facility, regardless of local resource constraints, and takes only a few minutes.
- NIHSS is efficient and free, providing essential value to patients while optimizing clinical operations and resources.
Data-Driven Results
The implementation of the dizziNIHSS initiative, combined with comprehensive training and ongoing feedback for clinicians, has increased use of the NIHSS for atypical neurological symptoms at USACS-staffed emergency departments, from 17% to 73%. Patients cared for by USACS clinicians have up to a four times greater chance of receiving timely and accurate stroke diagnoses.
“The dizziNIHSS initiative here at USACS is a prime example of fulfilling our mission to care for patients,” said Dr. Amer Aldeen, Chief Medical Officer of USACS, who coined the label, “dizziNIHSS,” and co-developed the initiative with Dr. John Bedolla, USACS National Director of Risk Science. “Our national physician-owned practice serving hundreds of community emergency departments collaborating with a powerhouse academic institution of Penn Medicine’s caliber is exactly the kind of innovation we need to drive healthcare forward.”
"We are excited to collaborate with USACS in using the dizziNIHSS method, reinforcing our commitment to early and accurate diagnosis of all strokes, anterior and posterior," said Dr. Benjamin Sun, Professor and Chair of Emergency Medicine at the University of Pennsylvania Perelman School of Medicine.
"The dizziNIHSS initiative aligns with our efforts to enhance patient safety and ensure that critical assessments are never overlooked," stated Dr. Jenice Baker, Chair of Emergency Medicine at Pennsylvania Hospital.
"Partnering with Penn Medicine to implement this evidence-based, cost-effective, and operationally efficient approach demonstrates our shared dedication to improving outcomes and reducing the risk for missed strokes," added Dr. Bedolla.
