Northern Ontario Research Initiative Enhances Dizziness Care

A new research initiative in Northern Ontario aims to significantly improve emergency care for patients experiencing dizziness. Funded by a generous investment of $757,350 from the Canada Institutes of Health Research, the collaboration between Health Sciences North and NOSM University focuses on refining a clinical tool intended to enhance patient outcomes for this common yet complex complaint.

The study will validate the Sudbury Vertigo Risk Score, a structured assessment designed to help physicians determine a patient’s immediate risk when they present with dizziness in emergency settings. This tool aims to streamline decision-making processes and improve care for patients in urgent situations.

Addressing a Common Emergency Department Challenge

Dizziness is a frequent yet diagnostically challenging issue in emergency departments. According to Dr. Robert Ohle, the study’s lead, this symptom complicates assessments for emergency medicine physicians. He noted, “Dizziness is a really common complaint in the emergency department and it’s tough for emergency medicine physicians because we don’t have great guidance on deciding which patients are suffering from a serious diagnosis and who is safe to be discharged home.”

The research seeks to provide essential guidance by rigorously testing the new risk evaluation scale, ensuring it effectively aids emergency physicians in identifying high-risk patients. Additionally, this initiative will enhance the education of NOSM University students about this prevalent emergency department presentation.

Direct Benefits for Northern and Rural Patients

The partnership between Health Sciences North and NOSM University reflects a commitment to addressing healthcare disparities in Northern Ontario. Dr. Michael Green, president of NOSM University, emphasized the value of integrating research, teaching, and clinical practice. “When research, teaching, and clinical practice come together, patients – especially those in rural and northern communities – see the direct benefit,” he stated.

Given the geographic isolation of many Northern Ontario residents, accurate assessments are particularly urgent. “Northern Ontario patients often have to travel long distances to see specialists,” Dr. Ohle explained. “It’s crucial for us to accurately identify who needs to make that trip to see a neurologist or who requires advanced imaging.”

The research aims to distinguish between benign dizziness and symptoms indicative of serious conditions, such as strokes. Dr. Ravinder-Jeet Singh, a stroke neurologist, highlighted the stakes involved. “One of the serious causes of dizziness is stroke, and this study is designed to validate a clinical risk score to help identify who might be experiencing a stroke versus another cause of dizziness,” he said. “If validated, it could significantly impact how we assess and manage dizziness patients, especially in smaller rural sites that lack access to medical imaging.”

Fostering innovation and improving system efficiency are core objectives of this project. Dr. Green noted that the initiative exemplifies the innovative work between NOSM University and Health Sciences North, reinforcing the medical university’s critical role in the region’s healthcare ecosystem.

Once validated, the Sudbury Vertigo Risk Score is expected to yield systemic benefits, including reduced unnecessary hospital transfers, shorter emergency department wait times, and keeping low-risk patients closer to home. This initiative ensures that those identified as high-risk receive the urgent, specialized care they require promptly.

With the potential to transform emergency care for dizziness, this collaborative effort underscores the importance of research in improving healthcare delivery across Northern Ontario.
